CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of Provisional Application Ser. No. 60/088,070, filed on Jun. 5, 1998. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a frame-based workspace definition system and, more specifically, to a frame-based workspace definition system comprising a framework defined by interconnected frames with attached tiles and accessories, such as worksurfaces, overhead bins, pedestals and shelves, mounted on vertical hanging intelligence. In another aspect, the invention relates to a series of interconnected frames which have tiles detachably mounted thereto whereby the frames and tiles cooperate to define an interior set of raceways which cooperate between the interconnected frames to define an interconnected chamber throughout the system for the passage of electrical and data conduit therein. 
     2. Description of the Related Art 
     Workspace definition systems for open room areas, such as office space, have a matrix of interconnected frames which have tiles mounted thereto. The frames often can accommodate electrical and data conduit therein so that several ports or sockets are defined within the framework for the interconnection with office components, such as computers, typewriters, dictation equipment, etc. Often these types of data and sockets and even the electrical data conduit can be provided directly within partition tiles mounted on the framework. 
     It has been found that the routing of electrical data conduit throughout these types of prior art office space partition systems can be difficult. Further, if the data and electrical connectors or sockets are provided in the tiles, these tiles must often be replaced or rewired with a new connector if the data and electrical needs of the office space partition system change over time. These types of rewiring of electrical and data conduit and the inability of prior art systems to easily accommodate new electrical and data systems have increased the time, expense and frustration with these systems. 
     SUMMARY OF THE INVENTION 
     The invention relates to an improved workspace management system for dividing a space into separate work areas comprising a rigid structural framework formed of rigid rectangular frames rigidly joined together at the edges thereof to form at least one work area. Each of the frames have outer faces on opposite sides thereof and openings on the opposite sides of the frames and a plurality of interchangeable tiles, with each of the tiles having a connector cooperating with the openings on the frames for removably mounting said tiles to the frames for ease of placement on and removal from the frames. The tiles are mounted to the outer faces of the frames to substantially cover both sides of the frames from a bottom portion thereof to a top thereof in juxtaposed parallel relationship. 
     In one improved embodiment, the invention relates to at least one of the frames comprising at least one load rail mounted horizontally between a pair of vertical rails and U shaped in cross section, the upper ends of the legs of the U shape having a reinforcing lip thereon. A pair of the tiles are mounted to the frames form a horizontal access slot therebetween. The horizontal access slot between the pair of the tiles is positioned in register with the upper ends of the legs of the U shaped load rail. The reinforcing lip can comprise an inwardly rolled portion forming a hook. The component can have a bracket mounted to the load rail and supported by the at least one frame. The bracket can be slidably mounted to the load rail. 
     Electrical power blocks can be mounted within the load rail inwardly of the component bracket whereby the bracket can slide along the rail. The bracket can be slidably mounted to the rail. The load rail can have at least one internal rib on bottom surface. The bracket on the component can seat behind the internal rib. The component can be any office furniture component such as a work surface or a cabinet. The component can have a first width, the frame has a second width and the first width can be different than the second width. The bracket can comprise a first portion adapted to mount to the load rail and having one of a flange and a slot and a second portion mounted to the component and having the other of a flange and a slot, wherein the flange is adapted to be removably mounted within the slot to removably mount the component to the first portion of the bracket. The U shape in the load bar can form a horizontal recess and the vertical rails can have an opening in register with the horizontal recess for routing conduit throughout the framework. 
     In another embodiment, each of the frames can further comprise a pair of opposed vertical rails having edge faces thereon. The edge faces can be interconnected with the outer faces of the vertical rails by ramped portions which are at an acute angle with respect to the edge faces and the outer faces. A series of aligned vertical slots can be provided in the ramped portions. The tiles can extend horizontally at least as far as the vertical slots to block light from passing directly from one side of the frame to the other side of the frame through the aligned vertical slots. 
     The edge face on each vertical rail can have a projection and a recess both extending along the vertical length of the rail in laterally spaced juxtaposed relationship to one another whereby the projection on one end face is received within the recess on an adjacent end face when a pair frames are placed into edge abutment with one another to prevent light from passing between the abutting end faces. 
     The frame can have a threaded opening in a lower portion thereof and the frame can further comprise at least one floor-engaging glide having a threaded shaft which is threadably received in the threaded opening in the frame. The threaded shaft can have a hexagonal head on an upper portion thereof whereby the at least one glide can be adjusted relative to the frame lower portion by a conventional socket tool when the frames are assembled. The frames are rigidly joined together by bolts which extend through abutting edge faces of the frame. 
     In an additional embodiment, the invention relates to one of the edge faces of the rigid rectangular frames further comprising a threaded aperture and another of the edge faces of the rigid rectangular frames has an aperture in registry with the threaded aperture of adjacent rigid rectangular frames and threaded bolts extending through the apertures of the another edge faces and threadably received in the threaded apertures in the one edge faces of adjacent rigid rectangular frames to rigidly join the rigid rectangular frames together. 
     The threaded aperture can comprise an integral threaded sleeve having a thickness greater than the thickness of the one edge face. The integral threaded sleeve can comprise a flow drilled extruded length of material formed inwardly from the one edge face. 
     In a further embodiment, the invention relates to the upper rail upper portion having a reinforcing lip thereon adapted to support at least one modular component. The component can have a bracket mounted to the reinforcing lip of the upper rail. The reinforcing lip can comprise an inwardly rolled portion forming a hook. The upper rail can have at least one internal rib on bottom surface. The bracket on the component can seat behind the internal rib. 
     The at least one modular component can be a cabinet. The at least one modular component can comprise a frame mounted generally perpendicular to the upper rail intermediate the ends thereof. A bracket can be rigidly mounted to the perpendicular frame and can have a flange mounted over the reinforcing lip of the upper rail. The component can have a first width, the frame can have second width and the first width can be different than second width. 
     The vertical rails can have an opening in register with the channel in the upper rail for routing the electrical/data cables throughout the framework. The rigid framework can comprise a first rigid frame positioned with respect to a second rigid frame in a generally perpendicular relationship intermediate the edge faces thereof and a first bracket can be rigidly mounted to the first frame and have a flange mounted to an upper portion of the second frame. A second bracket can be rigidly mounted to a lower portion of the first frame and have a flange mounted to a lower portion of the second frame. 
     In yet an additional embodiment, at least one bracket can be mounted to a portion of an edge face of a taller frame above a shorter frame. A cover can form an open-sided channel with end portions mounted to a bracket, thereby leaving the channel open for routing electrical/data cables therethrough. The end portions can also include a projection mounted to the bracket. The bracket can have outwardly extending support flanges and the cover can have inwardly directed ends which are snap-fit behind the support flanges. 
     In a further embodiment, a spacer can comprise at least one bracket having a generally vertical portion mounted to edge faces of adjacent frames and a generally horizontal portion having at least one of a slot and a projection. A cover can have the other of the slot and the projection in register with the one of the slot and the projection on the spacer, whereby the cover is removably mounted to the spacer to conceal the area between the adjacent frames. 
     The generally horizontal portion of the spacer can have a central opening adapted to receive electrical/data cables therethrough. The cover can have a central opening in register with the spacer central opening for routing of electrical/data cables therethrough. The cover can have inwardly-directed flanges thereon which are received behind edges of the generally horizontal portion of the spacer. The frame can have alignment openings and mounting apertures on the edge faces, the spacer can have alignment tabs which extend into openings in frame. At least two adjacent frames can be joined at 90, 135 or 180 degree angles with respect to one another. Further, three adjacent frames can be joined at a 90 degree angle therebetween. The spacer can have a threaded nut mounted thereto and the spacer can be secured to the edge faces of adjacent frame by a threaded fastener which extends through the edge face of the frame and is threaded onto the nut. 
     In another embodiment, the frame can have a bump rail extending outwardly from a lower portion thereof to a greater extent than the plurality of interchangeable tiles to protect lower edges of the tiles from damage by occupants of the system or the operation of floor cleaning devices. The bump rail can have at least one opening adapted to receive electrical/data cables routed into the system from a floor surface. The bump rail can have at least one elongated recess in which a lower edge of one of the plurality of interchangeable tiles is received. 
     In an additional embodiment, each of the main frames can further comprise a pair of opposed vertical rails having an opening at each upper end thereof, and an inverted U-shaped extension frame having a pair of depending legs, each leg having a cross-sectional shape congruent with the cross-sectional shape of the opening on the vertical rail upper ends. The extension frame can thereby increase the overall height of the main frame when the legs are mounted within the openings. 
     The depending legs of the extension frame can be bolted to the vertical rails. The depending legs of the extension frame can be of a sufficient length to prevent the extension frame from rocking with respect to the main frame. The depending legs of the extension frame can be U-shaped in cross section. 
     In yet a further embodiment, the invention relates to a filler frame having a horizontal dimension less than a given distance, and an adjustable rod mounted to the filler frame and to a filler bracket to secure the filler frame to the filler bracket. The adjustable rod can be rigidly secured at one end to the filler bracket and rigidly secured in an adjusted position to the filler frame. 
     In another embodiment, each of the edge faces of the rigid rectangular frames can have a projection and a recess, both extending along a vertical length of the rigid rectangular frames in juxtaposed relationship to one another whereby the projection on one end face is received within the recess on an adjacent end face when a pair of the rigid rectangular frames are placed into abutment with one another to prevent light from passing between the abutting end faces.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIG. 1 shows a frame-based workspace definition system  10  supported on a floor surface  12  of an open workspace, such as that typically found in an office environment. The workspace definition system  10  comprises a series of interconnected frames  14  which subdivide the workspace into smaller areas, often referred to as partitions. It will be understood that the workspace definition system  10  can also be provided to define open floor plans as opposed to the partitioned environment which is well known in the art. 
     Each of the frames  14  supports one or more tiles  16  to create walls within the workspace as defined by the interconnected frames  14 . The frames and tiles  14  and  16  can be of various sizes to define walls which extend floor-to-ceiling height or some intermediate height between the floor  12  and the ceiling (not shown). Further, frames  14  and tiles  16  of varying heights can be intercombined to define wall heights which vary depending upon the functionality and office aesthetics desired by the combination. A single tile  16  is typically mounted to either side of a frame  14 , however, multiple tiles  16  can also be hung on a single side of a particular frame  14  or in combination with other accessories, such as overhead bins  18 , shelves  20 , and pedestals or file cabinets  22 . One or more smaller tiles  16  can be provided on one or both sides of a particular frame  14  to cover the area of one side of the frame  14  not occupied by another hanging component, such as the bin  18 , shelf  20  or file cabinet  22 . Thus, a smooth aesthetic appearance of the workspace definition system  10  is maintained. 
     FIG. 1 also shows several worksurfaces  24  supported on the frames  14  preferably at a comfortable working height for an occupant of the workspace definition system  10 . The worksurfaces  24 , as will be described further below, can be mounted in cantilever fashion to interconnected frame  14  and can also be supported at an opposite end by one or more legs  26  as shown in FIG.  1 . 
     The layout shown in FIG. 1, for the workspace definition system  10 , should not be construed as limiting, but rather, any number of combinations of interconnected frames  14  having tiles  16  and components  18 - 24  mounted thereon can be achieved in any arrangement desired for a particular aesthetic appearance and functionality of the workspace in which the system  10  is located. 
     FIG. 1 also shows several covers mounted around exposed peripheral edges of the framework defined by the interconnected frames  14 . For example, top caps  28  are mounted along upper edges of the frames  14 , corner caps  30  are mounted to an upper surface between two or more interconnected frames  14  to conceal an upper surface of the joint therebetween, end covers  32  are mounted along exposed vertical edges of the workspace definition system IO, and corner covers  31  are mounted to an upper surface of one frame  14  and along exposed vertical edges of the workspace definition system  10 . Corner covers  31  provide for a continuous, uniform appearance when two or more adjacent frames  14  have different vertical heights. 
     FIG. 1 also shows an electrical raceway cover  34  mounted adjacent to a worksurface  24  provided with a socket opening  36  whereby the raceway cover  34  is either detachable from the frame  14  or movable between an open and a closed position. The raceway cover  34  is shown in the closed position in FIG.  1 . When detached or moved to the open position, the interior of the frame  14  can be accessed such as for routing electrical and data conduit and adding, removing, or splicing other connections therewith. 
     FIG. 2 shows the workspace definition system  10  of FIG. 1 with the tiles  16  removed to show the interior of the interconnected frames  14 . The components  18 - 24  are shown mounted to the frames  14 . Top caps  28 , corner caps  30 , corner covers  31 , end covers  32 , and raceway covers  34  are shown exploded from the frames  14  to reveal each frame  14  comprising interconnected vertical rails  50  with generally horizontal top, intermediate and foot rails  52 ,  54 , and  56 , respectively. 
     Each of the rails  52 ,  54  and  56  preferably has a U-shaped cross section so as to define an internal chamber or raceway for accommodating electrical and data conduit  40  as shown in FIG.  2 . The electrical and data conduit  40  can be routed within the top, intermediate and foot rails  52 ,  54  and  56 , through the vertical rails  50 , in between adjacent frames  14  and through any open space of a frame  14  so that the operable interconnection of office equipment components, such as computers, printers, fax machines, telephones, typewriters, etc., can be easily accomplished by merely removing one or more of the tiles  16 , and covers  28 - 34  routing the conduit  40  throughout the interconnected frames  14  and replacing the tiles  16 , covers and caps  28 - 34  as needed. 
     FIG. 3 shows a top schematic view of the workspace definition system  10  of FIGS. 1-2 showing that several components can be easily interconnected to the frames  14  with a minimum amount of hardware required. For example, several brackets  42  are shown mounted to particular frames  14 , and preferably the vertical rails  50  thereof, in cantilever fashion. In addition, the brackets  42  are also mounted to a particular component, such as a worksurface  24 , to support the component upon the interconnected frames  14 . Further, the overhead bins  18 , shelves  20  and file cabinets  22  are shown mounted to the interconnected frames  14  in similar fashion. Thus, it will be readily apparent from an examination of the workspace definition system  10  that the selection, arrangement and configuration of the frames  14  and their associated components can be easily designed and re-designed with a minimum of effort. 
     FIG. 4 is an exploded perspective view showing, among other things, a single frame  14  and an associated top cap  28 . As previously described, the frame has a top rail  52 , intermediate rail  54  and foot rail  56  extending in generally horizontal fashion between a pair of vertical rails  50  so that the frame  14  has a generally rectangular configuration. The frame  14  is shown as also having a bump rail  58  mounted to the base of a pair of vertical rails  50 , and a foot rail  56  to provide stability to the frame  14  and allow the frame  14  to have a free standing capacity on the floor surface  12 . 
     The vertical rail  50  of the frame  14  is shown in greater detail in FIGS. 5-8, respectively. The cross section of the vertical rail  50  is shown in FIG.  5  and comprises a leading face  60 , a trailing face  62  located oppositely therefrom and first and second side faces  64  and  66 , respectively, extending between the leading and trailing faces  60  and  62  along opposite ends thereof. Although the vertical rail  50  can be made as a solid member having apertures located at selected areas therein, the vertical rail  50  is preferably formed as a hollow member whereby the faces  60 - 66  form the periphery of the vertical rail  50 . A chamber  68  is formed within the interior of the vertical rail  50  and allows for routing of electrical and data conduit  40  therethrough. A similar chamber is formed within the interior of the top rail  52 , intermediate rail  54 , and front rail  56  which also allows for routing of electrical and/or data conduit  40  therethrough. 
     FIG. 6 shows a side elevational view of the first side face  64  of the vertical rail  50 . It will be understood that the second side face  66  of the vertical rail  50  is a mirror image thereof and will be referred to with common reference numerals. The first side face  64  comprises an elongated tile  70  provided with a ramped portion  72  with a U-shaped groove  74  located therebetween. The ramped portion  72  extends between the U-shaped groove  74  and the leading face  60  of the vertical rail  50 . Several vertically-aligned slots  76 , often referred to as “vertical hanging intelligence,” extend the length of the ramped portion  72  and are provided for receiving mating hooks on components  18 - 24  and brackets  42  as will be further described so that these components can be mounted as shown in FIGS. 1-3. The elongated tile  70  includes alternating first and second apertures  78  and  80  which extend in an alternating pattern along the length of the elongated tile  70 . 
     The leading face  60  is shown in FIG.  5  and in greater detail in FIG.  7 . The leading face  60  comprises an elongated tile  82  having an upper U-shaped aperture  84  and several elliptical apertures  86 . A pair of mounting apertures  88  are interspersed between each of the elliptical apertures  86  on the length of the elongated tile  82 . As can be seen in FIG. 7, the slots  76  on the ramped portion  72  of the first and second side faces  64  and  66  are visible in FIG. 7 adjacent to each edge of the elongated tile  82  of the leading face  60 . The leading face  60  is the portion of the vertical rail  50  which faces an adjacent leading face  60  of a vertical rail  50  of an adjacent frame  14  so that apertures  84 - 88  are generally horizontally aligned when a pair of leading faces  60  are so positioned. Thus, data conduit located in one frame  14  can extend through one or more of the apertures  84 - 88  into the adjacent frame  14 . 
     The trailing face  62  of the vertical rail  50  is shown in FIG.  5  and in greater detail in FIG.  8 . The trailing face  62  comprises an elongated stile  90  with elliptical apertures  92  aligned with the mounting apertures  88  on the leading face  60 . Mounting apertures  88  comprise a flow drill aperture  89  and an opposed attachment aperture  91 . A tool, such as a ratchet or wrench can be inserted within the elliptical apertures  92  to tighten a fastener (not shown) provided within one of the mounting apertures  88  to interconnect a pair of adjacent frames  14 . It will be understood that each of the apertures on the trailing face  62  can readily accommodate electrical and/or data conduit  40 . 
     Alternatively, as can be seen in FIG. SA the vertical rail  50  can be configured with a leading face  60  having a flow drill aperture  89 , and a trailing face  62  having a clearance aperture  92 . With such a configuration, a pair of vertical rails  50  can abut together along each of their respective leading faces  60 . Although not shown, it is likewise contemplated that the flow drill aperture  89  can be associated with the trailing face  62 , and the clearance aperture  92  can be associated with the leading face  60 . The only limitation with regard to the flow and clearance apertures  89  and  92 , respectively, is that together they must cooperate to, in turn, provide a configuration such that a pair of vertical rails  50  are adjoined in a substantially flush manner. 
     FIG. 9 shows an assembled frame  14  with the top, intermediate, and foot rails  52 ,  54 , and  56  interconnected between a pair of vertical rails  50 . As further shown in FIG. 9, the slots  76  on the ramped portion  72  of the first and second side faces  64  and  66  of each vertical rail are visible from the front elevational view shown in FIG.  9 . The first and second apertures  78  and  80  are provided along the vertical height of the vertical rail  50  of the frame  14 . 
     Each of the top, intermediate and foot rails  52 ,  54 , and  56  have an elongated wall  94  provided with a U-shaped cross section as shown in FIG.  9 A. The elongated wall  94  preferably defines an interior chamber  96  which serves as a raceway for receiving electrical and data conduit  40  therein. A bottom portion  98  of the wall  94  has a pair of elongated, longitudinal ribs  99  thereon which provide reinforcement to the rails  52 ,  54  and  56 . 
     As further shown in FIG. 9, the top, intermediate and foot rails  52 ,  54  and  56  can also be provided with first and second apertures  78  and  80 , respectively, spaced along the width of the U-shaped elongated wall  94  of each member and configured similarly to those on the vertical rails  50 . As shown in FIG. 9, preferably a pair of first apertures  78  are located adjacent each end of the members  52 ,  54  and  56  as well as at a central portion thereof. A pair of second apertures  80  are preferably located on either side adjacent to the first aperture  78  located at a central portion of each rail  52 ,  54  and  56 . These apertures  78  and  80  can be used for hanging tile  16  or, if configured properly, components  18 - 24  intermediate the ends of a particular frame  14  where space requirements of either a tile  16  or components  18 - 24  so dictate. 
     Each of the top, intermediate and foot rails  52 ,  54  and  56  can be provided with inwardly-extending hooks  112  extending into the interior chamber  96  of the elongated wall  94 . Further, a floor portion  98  of the elongated wall  94  can have a pair of spaced upstanding ribs  99  provided for structural reinforcement of the wall  94  as well as several spaced openings  118  therein. Ribs  99  can also be used for off-module hanging of components  18 - 24 . 
     The top, intermediate and foot rails  52 ,  54  and  56  can be welded at either end between a pair of vertical rails  50  having their trailing face  62  facing toward one another so that the vertical rails  50  and top, intermediate and foot rails  52 ,  54  and  56  form an integrally welded structure. Alternatively, the rails  52 ,  54  and  56  can be removably mounted between a pair of aligned vertical rails  50  by a clip  100  as shown in FIGS. 10-11. The clip preferably comprises a plate  102  having a depending flange  104  provided with a laterally-extending connector  106  at a terminal end thereof. The connector  106  is provided with a pair of spaced-mounting apertures  108  adapted to receive a threaded fastener therein. An upper end of the plate  102  is also provided with a pair of spaced-mounting apertures  108  as well. The clip  100  is also provided with a pair of forwardly-extending arms  110 . 
     The clip  100  is preferably mounted to a mounting aperture  93  within the elongated tile  90  of the trailing face  62  so that the arms  110  extend toward the opposing vertical rail  50  of the frame  14 . The rail  52 ,  54  and  56  is mounted on the arms  110  so that the hooks  112  engage over the arms  110  to provide a secure support for mounting the rail  52 ,  54  and  56  between the vertical rails  50 . 
     FIG. 12 shows an exploded perspective view of a stacker frame assembly  120  mounted atop a frame  14  comprising the rails  52 ,  54  and  56  as previously described. The stacker frame assembly  120  is used to increase the height of a standard frame  14  when a framework of increased height is desired. The stacker frame assembly  120  comprises a pair of vertical rails  122  supporting a top rail  124  therebetween at an upper end thereof. Each of the vertical rails  122  are provided with a reduced-diameter depending flange  126  which is preferably shaped to correspond with the interior of a vertical rail  50  as shown in greater detail in FIG.  5 . 
     The vertical and top rails  122  and  124  of the stacker frame assembly  120  are preferably configured with all of the apertures and other discontinuities described with respect to the vertical rails  50  and top rail  52  of a frame  14 . Further, the reduced-diameter flanges  126  which depend from each of the vertical rails  122  are also provided with the corresponding apertures and discontinuities of the vertical rail  50  of a frame  14  to align with those apertures and discontinuities of the vertical rails  50  when axially inserted therein. 
     A stacker frame assembly  120  is mounted atop a frame  14  by inserting the reduced-diameter flanges  126  on each vertical rail  122  within an aperture  128  located atop each vertical rail  50  of the frame  14 . The reduced-diameter flange  126  is thereby received within the aperture and extends into the interior chamber  68  of the vertical rail  50  and can be secured thereto by fasteners  130 . Alternatively, the stacker frame assembly  120  can be welded atop the frame  14  in a known fashion if the stacker frame assembly  120  is to be permanently mounted thereon. 
     The top cap  28  is shown in FIGS. 1-4 and in greater detail by the cross section of FIG.  13 . The top cap  28  comprises an elongated member  132  having a smooth arcuate upper surface  134  and a stepped lower surface  136 . The lower surface  136  comprises a first step  138  located adjacent each distal end  140  thereof and a second step  144  located slightly lower and inwardly than the first step  138 . Each second step  144  terminates in a depending leg  146 . 
     In the cross section shown in FIG. 13, the top cap  28  is shown mounted atop the upper ends of a pair of vertical rails  50  along a top rail  52 . The upper ends of the vertical rail  50  and top rail  52  are preferably located adjacent to the second step  144  while a tile  16  mounted to either side of the frame  14  preferably has an upper edge located directly adjacent the first step  138 . The distal ends  140  preferably align with exterior surfaces of the tile  16 . The arcuate upper surface  134  extends between the distal ends  140  of the top cap  28  to provide a smooth outer appearance to the workspace definition system  10 . 
     A top cap clip  148  is shown in FIG.  13  and in greater detail in FIG.  14 . The top cap clip  148  comprises a plate  150  having upwardly-extending claw  152  and a downwardly-extending arcuate arm spring  154 . The claw  152  preferably has a pair of outer tines  156 , each provided with an inwardly-extending angular flange  158  and a center tine  160  which is preferably bent inwardly at  162  to form a C-shaped cross section. The arm spring  154  preferably comprises an elongated member having an inwardly-curved portion  164  which has an inherent resiliency. 
     The top cap clip  148  is preferably mounted to each depending leg  146  into the claw  152  so that the outer tines  156  abut one side of the leg  146  and the center tine  160  is located on the opposite side thereof. The resilience of the tines  156  and  160  cause the leg  146  to be securely gripped therebetween. A top cap clip  148  is preferably mounted in a spaced relationship along the length of a top cap  28  to both of the depending legs  146  so that the curved portions  164  of the arm spring  154  on opposite legs  146  of the top cap  28  extend outwardly therefrom. 
     The top cap  28  is mounted atop a frame  14  by urging the top cap  28  with attached clips  148  downwardly onto an upper surface of the vertical rails  50  and top rail  52  so that the arm spring  154  on each leg  146  is compressed inwardly. As the top cap  28  is urged further downwardly onto the frame  14 , the curved portion  164  bears against the interior surface of the elongated wall  94  of the top rail  52  until the curved portion  164  lodges beneath the hooks  112  at the upper edge of the elongated wall  94 . The curved portion  164  of the arm spring  154  of the top cap clip  148  is received therebeneath to retain the top cap  28  atop the frame  14 . 
     A support clip  166  for providing reinforcement to the top cap  28  shown in FIGS. 1-4 and FIG. 13 atop the frame  14  is shown in FIG.  15 . The support clip  166  comprises a plate  168  having a pair of depending ends  170  and a lateral edge  172  provided with a spring clip  174 . The spring clip  174  comprises a depending wall  176  interconnected to an upwardly-standing wall  178  by a resilient bight  180 . An upper end of the upwardly-extending wall  178  can be provided with an angular flange  182  to provide a bearing surface  184  within a gap  186  located between the walls  176  and  178 . 
     The support clip  166  is provided for the purpose of supporting the top cap  28  from collapsing along the length thereof at points in lieu of or in addition to the top cap clip  148 . A depending leg  146  of the top cap  28  can be inserted within the gap  186  between the walls  176  and  178  so that the bearing surface  184  is held against the leg  146  by the resilience of the bight  180 . The plate  168  with depending walls  170  can thereby be inserted over a portion of a top rail  52 , such as over upper portions of the elongated wall  94  thereof to support the top cap  28  atop the frame  14  and provide further support and structural integrity thereto. 
     The bump rail  58  is shown in FIG.  4  and in greater detail in FIG.  16  and comprises an elongated member  188  having several elongated spaced apertures  190  therein for accommodating the passage of wires from a sub-floor surface. Each longitudinal edge of the bump rail  58  is provided with a depending wall  192  which terminates in a laterally-extending wall  194 . Each of the walls  194  terminates in a reversibly-curled foot  196 . A glide  200  supports the bump rail  58  above the floor so that the bump rail  58  can be adjustably supported relative to the floor  12  so that the frame  14  can be supported at a predetermined height. Although not shown, a base tile trim cover can be applied to the bump rail  58  to, in turn, protect the lower portion of tile  16  from personnel and/or vacuum cleaners inadvertently contacting such tile. 
     As shown in greater detail in FIG. 4, the bump rail  58  is mounted to a lower surface of the frame  14  by several fasteners  198 . Further, a pair of glides  200 , which generally comprise a threaded shaft  202  and a conical foot  204  can also be mounted within apertures in the bump rail  58  and engaged within the frame  14 , such as in the foot rail  56  or within an aperture (not shown) within a lower surface of each of the vertical rails  50  of a frame  14 . 
     FIG. 17 shows a fragmentary perspective view of a first embodiment of a connector  210  used for interconnecting two or more adjacent frames  14  in a particular configuration, such as at a 90°, 135° or 180° angular relationships with respect to an adjacent frame  14 . The connector  210  comprises a plate  212  provided with a central aperture  214 . Several upstanding flanges  216  are provided around the periphery of the plate  212  at a desired angular spacing. It will be understood that a leading face  60  of a frame  14  can be mounted to each of the upstanding flanges  216  so that, depending upon the angular spacing of the flanges  216  around the plate  212 , two or more frames  14  can be supported at a desired angular spacing. 
     Each of the upstanding flanges  216  comprises a plate  218  which has an upper edge  220  provided with a central indentation  222  therein. A lower edge  224  of the central indentation  222  has a radially-extending hook  226  which, as shown best in FIG. 17A, extends upwardly and radially outwardly from each flange  216 . 
     Each upstanding flange  216  is also provided with a hexagonal aperture  228  which receives a threaded sleeve  230  therein. The threaded sleeve  230  is provided with a pair of annular flanges  232  located on either side of a hexagonal surface  234  on the sleeve  230  adapted to be inserted within the hexagonal aperture  228  so that the annular flanges  232  abut both sides of the flange  216  around the hexagonal surface  234 . Thus, the engagement of the hexagonal surface  234  within the hexagonal aperture  228  prevents the threaded sleeve from being rotated within the hexagonal aperture  228  while the abutment of the annular flanges  232  on either side of the flange  216  prevents the sleeve  230  from being axially removed from the aperture  228 . 
     As best shown in FIGS. 17 and 17A, the connector  210  is mounted to two or more adjacent frames  14  by aligning the threaded sleeve  230  on each flange  216  with one of the mounting apertures  88  thereon so that the hook  226  passes into one mounting aperture  88  (i.e., flow aperture  89 ) and the threaded sleeve is aligned with another mounting aperture  88  (i.e., opposed attachment aperture  91 ). 
     The hook  226  is used to align the connector  210  with the mounting aperture  88  on the frame  14  to ease interconnection of the connector  210  with the frame  14 . Once the threaded sleeve  230  is aligned with the mounting aperture  88  and the hook  226  is passed within an adjacent mounting aperture  88 , a fastener  236  is passed through the mounting aperture  88  into the threaded sleeve  230  and tightened as needed. Fasteners  236  can be mounted within all of the threaded sleeves  230  on each of the flanges  216  to interconnect as many frames to the connector  210  as desired. A tool (not shown), such as a wrench, ratchet or powered driver, can be passed through elliptical apertures  92  on the trailing face  62  of a vertical rail  50  so that a head portion  238  on the fastener  236  can be engaged with the tool and the fastener rotated easily and quickly. 
     As can be seen in FIG. 17, the first embodiment of the connector  210  is shown interconnecting three frames  14  at 90° angles with respect to one another. As shown in FIG. 18, a second embodiment of the connector  210  is shown which is adapted to interconnect a pair of frames  14  at 90° angles with respect to one another. A phantom outline portion of FIG. 18 shows a third embodiment of the connector  210 , when combined with the solid line portion of FIG. 18, provides a connector  210  adapted to interconnect four frames  14  at 90° angle with respect to one another. FIG. 19 shows a cross-sectional view of the connector showing the mounting of the sleeve  230  on the flange  216  in greater detail for such a 90° angle connector  210 . FIG. 20 shows a fourth embodiment of the connector  210  adapted to interconnect a pair of frames  14  at a 135° angle with respect to one another. It will be further understood that other embodiments of the connector  210  can be provided for interconnecting frames  14  at 90°, 135° and 180° angles with respect to one another. Further, other embodiments of the connector  210  can easily be contemplated for interconnecting two, three, four and even more frames  14  without departing from the scope of this invention. 
     FIG. 21 shows the end cover  32  for concealing a vertical joint between two or more adjacent frames  14  interconnected by one or more connectors  210 . The end cover  32  comprises an elongated cover  250  provided with several mounting trusses  252  at spaced vertical intervals along the length of the cover  250 . The cover  250  generally comprises an extruded member having a desired aesthetically-pleasing outer surface and is adapted to interfit between a vertical joint between two or more adjacent frames  14  to obstruct the interior of the joint between two or more adjacent frames  14  from view. The trusses  252  are mounted to the cover  250  in a conventional manner, such as by welding, fasteners, or the detachable engagement of a flange  254  on the cover  250  with a mating flange  256  on the truss  252  as generally shown in FIG. 21. A tab  253  is provided proximate the bottom portion of the end cover  32 , which can engage and, in turn, secure the end cover  32 , or any other structure therebelow. 
     FIGS. 22-24A show various embodiments of the cover  250  and truss  252  which are adapted to interfit with various embodiments of the connector  210  as shown in FIGS. 17-20. Each of the trusses  252  comprise a plate  258  having a central recess  260  preferably adapted to be aligned with the central aperture  214  on a connector  210 . A pair of flanges  262  are located on either side of the recess  260  and are adapted to be received by the connector  210  to mount the truss  252  thereto. 
     Three embodiments of the truss  252  and associated cover  250  are shown in FIGS. 22-24. It will be understood that each of the components  256 - 262  of the truss  252  are referred to with common reference numerals in the embodiments shown in FIGS. 22-24. FIG. 22 shows a truss  252  configured for mounting to a connector  210  for concealing a 180° joint or the three-way joint shown in FIGS. 17 and 17A. FIG. 23 shows an embodiment of a truss  252  configured to conceal the vertical portion of a joint between a pair of frames mounted by connectors  210  at a 90° angle with respect to one another. FIG. 24 shows an embodiment of the truss  252  configured to conceal the vertical portion of a joint between a pair of frames  14  mounted by connectors  210  at a 135° angle with respect one another. 
     The truss  252  can be mounted to a corresponding connector  210  between two or more interconnected frames  14 . In particular, the flanges  262  of the trusses  252  can fixedly engage the plates  212  of the connectors  210 . 
     As shown in FIGS. 21-24A, the cover  250  can be configured as needed to completely conceal the joint between two or more interconnected frames  14 . In any configuration, the cover  250  can preferably be provided with a pair of out-turned edges  268  which are adapted to directly abut the leading face  60  of a vertical rail  50  of an adjacent frame  14  so that the joint between two or more interconnected frames  14  is completely concealed. 
     As can be seen in FIGS. 1-2 a change of height corner cover  31  can be used when two or more adjacent frames  14  and associated tiles  16  have different heights. 
     The change of height of corner cover  31  allows electrical and/or data conduit  40  to be routed into and through such areas in a protected, yet non-restrictive, manner. Additionally, the change of height corner cover  31  can perform an aesthetic function inasmuch as it provides for a continuous, uniform cover surface for the frames  14 . FIG. 24A is a top plan view of the change of height corner cover  31  of FIGS. 1-2. In particular, FIG. 24A shows that the substantially rectangular chamber region  33  can readily accommodate electrical and/or data conduit  40 . 
     FIGS. 25-26 show an enlarged example of the corner cap  30  illustrated in FIGS. 1-3. The corner cap  30  has an upper surface  270  provided with a smooth aesthetically-pleasing surface which has peripheral edges  272  having depending portions which are adapted to directly abut an adjacent top cap  28  or an upper edge of an adjacent end cover  32  to provide a smooth transition between these components and conceal an upper surface of a joint between two or more interconnected frames  14 . An underside  274  of the corner cap  30  is provided with depending flanges  276  which depend downwardly from the underside  274  to further extend beyond the peripheral edges  272  thereof. The depending flanges  276  cooperate to define an alignment structure for mounting the corner cap  30  upon the upper edge of a joint between interconnected frames  14 . 
     The corner cap  30  is generally placed onto the upper surface of the joint between interconnected frames  14  after the frames  14  have been mounted together by connectors  210 . The corner cap  30  is placed downwardly onto the upper surface of the joint so that the depending flanges  276  thereof abut the upper surfaces of the interconnected frames  14 . For example, the upper surfaces of the frame  14  can be engaged within a small recess  178  adjacent the depending flanges  276  so that the corner cap  30  securely rests thereon. The corner cap  30  can be placed atop a corner cover  31  and secured thereto by fixedly engaging the flanges  276  of the corner cap  30  with the apertures  264  of the corner cover  31 . 
     FIG. 27 shows a front elevational view of a wall starter rail  290  comprising an elongated panel tile  292  provided with several spaced sets of mounting apertures  294  and an elongated vertical groove  296 . The mounting apertures  294  are preferably configured to align with the mounting apertures  88  provided along the leading face  60  of the vertical rail  50  of the frame  14 . 
     The wall starter rail  290  is provided for mounting a frame  14  to an existing wall of the workspace so that the workspace definition system  10  can extend to, and be mounted with, the existing wall. Once the wall starter rail is mounted to an existing wall, the frame  14  can be placed adjacent the wall starter rail  290  and mounted thereto by passing fasteners into the aligned mounting apertures  88  and  294  in the frame  14  and wall starter rail  290 , respectively. The vertical groove  296  is provided so that a joint cover, such as end cover  32  or a vertical edge of a tile  16 , can fit therein so that a smooth transition between the existing wall, the wall starter rail  290 , and the frame  14  is provided in an aesthetically-pleasing manner. 
     FIG. 28 shows an exploded perspective view of a tile  16  provided with several first clips  300  and several second clips  302  mounted to a rear surface  304  of the tile  16  by fasteners  306 . The first clips  300  are preferably provided on the tile  16  to align with the first apertures  78  on the vertical rails  50  and top, intermediate, and foot rails  52 - 56  while the second clips  302  are provided to preferably align with the second apertures  80  on the vertical rails  50  and top, intermediate, and foot rails  52 ,  54  and  56 . As many of the first and second clips  300  and  302  can be provided to securely support the tile  16  on the frame  14  with the engagement of the first and second clips  300  and  302  within corresponding first and second apertures  78  and  80 , respectively, on a frame  14 . 
     A cross-sectional view of the first clip  300  is shown in FIG. 29 mounted to the rear surface  304  of the tile  16  by the fasteners  306 . The first clip  300  comprises a plate  308  provided with a pair of spaced apertures  310  for receiving the fasteners  306 . 
     An upper edge  312  of the plate  308  is provided with a laterally extending step  314 , which terminates in an upwardly extending flange  316 . An upper portion of the flange  316  is provided with an angularly extending flange  318 , which terminates in a curled edge  320 . A lower edge  322  of the plate  308  is provided with a laterally extending step  324 , which terminates in a depending wall  326 . 
     FIG. 30 shows a cross-sectional view of the second clip  302  mounted to the rear surface  304  of the tile  16  by the fasteners  306 . The second clip  302  comprises a plate  328  provided with a pair of spaced apertures  330  for receiving the fasteners  306 . A lower edge  332  of the plate  328  terminates in a laterally extending step  334  which, in turn, terminates in a downwardly and angularly extending flange  336 . The flange  336  terminates in a reversely curled edge  338 . 
     A tile  16  can be mounted to a frame  14  by angularly tilting the tile  16  so that the first clips  300  thereon are placed forwardly toward, and aligned with, the first apertures  78  on a frame  14 . The curled edge  320  on the first clips  300  are inserted within the aligned first aperture  78  as shown in FIG.  28 A. The tile  16  is then urged angularly upwardly so that first clip  300  is urged therein. 
     As shown in FIG. 28B, the second clip  302  is brought toward the aligned second aperture  80  in the frame  14  with the first clip  300  inserted within the first aperture  78  as shown by the arrow marked “A”. The tile  16  is then urged downwardly, as shown by the arrow marked “B” in FIG. 28B, to bring the tile  16  to the rest position as shown in FIG.  28 C. 
     Once the tile  16  is so mounted, the upwardly extending flange  316 , as offset from the rear surface  304  of the tile  16  by the step  314 , is retained behind the leading face  60  of the vertical rail  50 . In addition, the depending wall  326 , as offset from the rear surface  304  of the tile  16  by the step  324 , is also retained therebehind. The second clip  302  has the angularly-extending flange  336  retained behind the leading face  60  of the vertical rail  50  as offset from the rear surface  304  of the tile  16  by the step  334 . 
     The upwardly extending flange  316  abuts against a rear surface of the leading face  60  of the vertical rail  50  to hold the upper portion of the tile  16  against the frame  14  as shown in FIG.  28 C. Further, the angular configuration of the flange  336  on the second clip  302  acts as a “cam” surface to prevent a lower edge  340  of the second aperture  80  from sliding with respect to the step  334 . Thus, the lower portion of the tile  316  is also tightly retained against the frame  14  because the lower edge  340  of the second aperture  80  is not allowed to slide rearwardly with respect to the frame  14 . Thus, the first and second clips  300  and  302  provide a secure mounting of the tile  16  with respect to the frame  14  without requiring the use of conventional threaded fasteners between the tile  16  and frame  14 . Thus, the tile  16  can be easily removed by reversing the steps shown in FIGS. 28A-28C to expose the interior of the frame  14  for accessing the electrical and data conduit  40  routed therein. 
     FIGS. 28D-I show the installation of a glass tile assembly for integration with the workspace definition system  10  in accordance with the present invention. FIG. 28D shows an exploded perspective view of a glass tile assembly  600  comprising a pair of vertical rails  50  having trailing faces  60 , glass tile bottom rail  602 , glass material  604 , vertical molding strips  606 , horizontal molding strips  608 , side brackets  610 , and frames  612 . The vertical rails  50  extend generally parallel to each other, and the glass tile bottom rail  602  is secured between the vertical rails  50  in a generally perpendicular orientation. Both the vertical and horizontal molding strips  606  and  608 , respectively, are secured to the glass material  604  upon complete fabrication. As will be discussed in greater detail below, the side brackets  610  are secured to a pair of vertical rails by fasteners  130 . While the window has been disclosed as fabricated from glass material, it is likewise contemplated that any one of a number of polymeric resins including, but by no means limited to, acrylic resins are suitable for use. 
     FIG. 28E shows the interconnection of a glass tile bottom rail  602  between a pair of vertical rails  50  in the frame of FIG. 28D, which is adapted to receive a bottom portion of a glass panel therein. As further shown in FIG. 28E, upon assembly, the glass tile bottom rail  602  is secured to the trailing face  601  of each vertical rail  50  by fasteners  130 . The glass tile bottom rail  602  has a channel  614  for controllably receiving the lower portion of the glass material  604 . 
     FIG. 28F shows the mounting of a plurality of brackets  610  to the trailing face  601  of pair of vertical rails  50  of FIGS. 28D-28E, for receiving the vertical molding  606  of the glass material  604 . Upon further assembly, the side brackets  610  are secured by fasteners  130  to one side of each of the vertical frames  50 . 
     FIG. 28G shows the angular insertion of the glass material  604  with associated vertical and horizontal moldings  606  and  608 , respectively, into the channel  614  of the glass tile bottom rail  602 . Once the glass material  604  is inserted into the glass tile bottom rail  602 , the glass material  604  is rotated towards the vertical rail  50  until it contacts the plurality of previously secured side brackets  610 . 
     As can be seen in FIG. 28H, once the glass material  604  is positioned so that it contacts the plurality of side brackets  610  on one side of each of the vertical rails  50 , a plurality of side brackets  610  are secured by fasteners  130  on the other lateral surface of the vertical frames  50  to, in turn, secure the glass material  604  between the vertical frames  50 . 
     FIG. 28I is an exploded perspective view showing the mounting of a pair of frames  612  to both sides glass tile assembly to, in turn, complete the assembly of the window tile. Although not shown, it will be understood that a conventional top cap  28  can be mounted atop the glass tile assembly  600  for aesthetic purposes. Furthermore, inasmuch as the glass tile assembly utilizes vertical rails  50  as previously discussed herein, the glass tile assembly can readily accommodate electrical and/or data conduit  40 . Moreover, it will be further understood that a passthrough-tile assembly can be readily achieved by removing the glass material  604  from the assembly. Such a pass-through-tile assembly can be convenient for various tasks such as passing mail, and/or increasing airflow throughout the entire workspace system  10 . 
     FIGS. 31-32 show various configurations for the tile  16 . For example, in FIG. 31, the tile comprises a core  350  made from a suitable material, such as fiberglass, having a molded overlay  352  thereon which defines an inwardly-extending groove  354  on the rear surface  304  of the tile  16 . The core  350  and overlay  352  can be wrapped with various materials, such as a fiberglass layer  356  and an outer fabric covering  358 . An edge covering  364  can be wrapped around lateral edges of the tile  16 , within the inwardly-extending groove  354  and rearwardly to the rear surface  304  so that its peripheral edge  360  is retained within a groove  362  on the rear surface  304 . 
     The fabric covering  358  can then be wrapped around the edge covering  364  so that a peripheral edge  366  of the fabric covering  358  is disposed within the inwardly-extending groove  354  as defined by the portion of the edge covering  364  disposed therein. A spline  368  can then be disposed within the groove  354  to retain the fabric covering  358  between the spline  360  and the portion of the edge covering  364  disposed within the inwardly-extending groove  354 . 
     By these steps, the fabric covering  358  can thereby be tautly retained over a forward surface  370  of the tile  16  to prevent wrinkling or loosening of the fabric covering. Further, the removal of the spline  368  allows the fabric covering  358  to be easily removed to change the type and/or color of fabric covering  358  on a particular tile  16  so that the style or appearance of the tile  16  can be easily changed without requiring the purchase and installation of a new tile  16 . 
     FIG. 32 shows an alternative embodiment of the tile  16  comprising a core  372 , such as particleboard, with a foil scrim layer  374  wrapped therearound intermediate an outer fabric covering  376 . The fabric covering  376  of the tile  16  shown in FIG. 32 is wrapped around to the rear surface  304  of the tile  16  and mounted thereto, such as by stapling or an adhesive. 
     Alternatively, a tile  16  can be provided with a core material which has a vinyl coating adhesively mounted thereto or any other suitable covering known in the art to provide a desirable outer appearance to the tile  16 . 
     In yet another embodiment an acoustical tile can replace the conventional tile  16  as described herein. As shown in FIG. 32A an acoustical tile  680  includes a fiberglass member  682  which is attached to a rear face  684  of the tile with a polyvinyl side extending from the exterior which overlaps within the inside of a surrounding frame. A light block  686  can extend from a lower edge of the acoustical tile  680  so that when adjacent panels are mounted in a vertical relationship, light is prevented from extending between a seam (not shown) of the tiles due to the light block emanating over the seam between the tiles. Alternatively, a tackable tile having a particulate core, which allows the tile to receive thumb tacks, push pins, etc., can be used instead of the tile  16 . 
     Other types of forward surfaces  370  can be provided to the tile  16  as needed, such as a wipe-away marker board surface, a window, such as glass or an empty “passage” frame, a molded fiberglass tile, a vinyl-covered tile, and other acoustical tiles as typically used with tiles of these types. 
     FIGS. 33A-33C show the mounting of the raceway cover  34  within a gap between several tiles  16  mounted to a framework comprising several interconnected frames  14 . As described above, the raceway cover  34  generally comprises an elongated member having an opening  36  therein so that, when the raceway cover  34  is mounted to a frame  14 , the opening  36  can be aligned with an electrical or data socket (not shown) mounted to the frame  14  for interconnection with components, such as a computer, printer, fax machine, telephone, etc. 
     The raceway cover  34  preferably has a pair of rearwardly-extending upper and lower edges  380  and  382 , respectively, which are adapted to be mounted flush with adjacent edges of tile  16  and/or office components  18 - 24  to provide a smooth outer appearance to the workspace definition system  10 . Each of the upper and lower edges  380  and  382  can be provided with a detent  384  thereon which is adapted to receive a raceway cover bracket  386 . The raceway cover bracket  386  is adapted to engage the detents  384  at the upper and lower edges  380  and  382  of the raceway cover  34  and, in turn, be mounted within the first and second apertures  78  and  80  on a pair of vertical rails  50  of a frame  14 . 
     The raceway cover bracket  386  comprises an elongated member  388  having a rearward surface provided with first and second mounting flanges  390  and  392  and a forward surface provided with third and fourth mounting flanges  394  and  396 . The first and third mounting flanges  390  and  394  are preferably located adjacent an upper edge of the elongated member  388  and the second and fourth mounting flanges  392  and  396  are preferably located adjacent a lower edge of the elongated member  388 . The second mounting flange  392  is preferably located upwardly from the fourth mounting flange  396 . 
     The first mounting flange  390  comprises a pair of opposed L-shaped members  398  and  399 . The L-shaped member  398  faces upwardly and has an upper edge  400  provided an upwardly- and angularly-extending flange  402 . The angularly-extending flange  402  preferably extends beyond the upper edge of the elongated member  388  and the L-shaped member  398  and angularly-extending flange  402  cooperate to define a gap  404  with the upper portion of the elongated member  388 . 
     The second mounting flange  392  comprises an inverted L-shaped member  406  which extends rearwardly and downwardly with respect to the elongated member  388 . 
     The third and fourth mounting flanges  394  and  396  are identical members but disposed in an opposing relationship so that the fourth mounting flange  396  is a mirror image of the third mounting flange  394 . Thus, common reference numerals are described with respect to each. The third and fourth mounting flanges  394  and  396  comprises a laterally-extending plate  408  which has a detent  410  on an outer distal edge  412  thereof. The detent  410  extends upwardly from the third mounting flange  394  and extends downwardly from the fourth mounting flange  396  as shown FIG.  33 A. 
     A pair of brackets  386  can be mounted to a pair of vertical rails  50  in a frame  14  as best shown in FIG.  33 B. The bracket  386  is brought toward a first and a second aperture  78  and  80  in the vertical rail  50  in an angular position so that the first mounting flange  390  is tilted toward the first aperture  78  in the vertical rail  50 . The angularly-extending flange  402  is inserted within the first aperture  78  so that an upper edge of the first aperture  78  travels within the gap  404  between the first mounting flange  390  and the elongated member  388  of the bracket  386 . When the first mounting flange  390  has been inserted a sufficient extent within the first aperture  78 , the second mounting flange  392  is pivoted toward the second aperture  80  so that the second mounting flange  392  passes within the second aperture  80  until the bracket  386  is retained in a generally vertical position. 
     As best shown in FIG. 33C, the bracket  386  is then urged downwardly so that the L-shaped member  399  of the first mounting flange  390  engages over a corner edge of the first aperture  78  and the second mounting flange  394  engages over a lower edge of the second aperture  80 . The L-shaped member  398  of the first mounting flange  390  is retained against the rearward surface of the leading face  60  of the vertical rail  50  so that the bracket  386  is prevented from moving laterally with respect to the vertical rail  50 . Another bracket  386  can be mounted on an opposite side of the frame  14  to a pair of first and second apertures  78  and  80  as well. 
     The raceway cover  34  can then be snap-mounted to the pair of brackets  386  located on either side of the frame  14  by urging the detent  384  on the upper and lower edges  380  and  382  over the detents  410  on the third and fourth mounting flanges  394  and  396  so that the detent  384  is frictionally engaged behind the detent  410 . Preferably, the opening  36  in the raceway cover  34  is aligned with a data or electrical socket (not shown) in a circuit provided by the data and electrical conduit  40  running throughout the workspace definition system IO so that an occupant of the workspace definition system  10  can easily interconnect various office components to the electrical and data conduit  40 . 
     FIG. 33D shows an alternative embodiment of the raceway cover  34  and bracket  386  whereby the bracket  386  includes a hinged portion  414  which pivotally mounts to a socket  416  on the raceway cover  34  so that, when the bracket  386  is mounted to a pair of vertical rails  50  of a frame  14 , the interior of the frame  14  can be accessed by pivoting the raceway cover  34  to an open position. 
     FIG. 33E shows an alternative embodiment of the raceway cover  34  provided with a pair of upper and lower vertical brackets  700  and  702 , respectively, for receiving communication socket hardware and a slidable receptacle cover  704  disposed within longitudinal channels  706  on the raceway cover  34  which is adapted to be secured to a frame  14  (shown in dashed lines) of the workspace definition system  10  by the bracket shown in FIGS. 33A-33D. The brackets in accordance with FIG. 33E mount the access panel  34  for slidable movement between an opened and closed position, whereby in the open position, electrical and data conduit  40  passing within the framework, such as within one of the horizontal rails  52 ,  54  and  56 , can be accessed. 
     FIG. 33F shows an additional alternative embodiment of the raceway cover  34  of FIG. 33E wherein hinge brackets  708  pivotally mount the raceway cover  34  for movement between an open and a closed position and horizontal electrical brackets  710  receiving electrical and data communications hardware. Brackets  708  and  710  can be secured to their respective rails by fasteners  130 . 
     FIG. 34 shows a worksurface  24  in cross section. The worksurface  24  is provided with a peripheral groove  420  which extends inwardly from a vertical edge  422  of the worksurface  24 . The peripheral groove and vertical edge  420  and  422  cooperate to define a receiving surface for an edge molding  424 . The worksurface  24 , having upper and lower surfaces  426  and  428 , respectively, cooperates with an exterior surface  430  of the edge molding  424  to define a “soft” or contoured vertical sidewall to the worksurface  24 . 
     This contoured edge serves both to increase the aesthetics of the worksurface  24  as well as provide a function, if made from a soft or resilient material, of preventing an occupant of the workspace definition system  10  from injury while sitting adjacent a worksurface  24 . This safety feature is provided because any sharp corners, such as those shown at  432  inbetween the upper surface  426  and vertical edge  422  and the lower surface  428  and the vertical edge  422 , are given a smooth transition between the upper surface  426  and the lower surface  428 , thus concealing the corners  432 . 
     The molded edge  424  is shown in FIG. 35 removed from the worksurface  24  comprising a convex upper surface  434  which arcs downwardly and terminates in a concave lower surface  436  defining the exterior surface  424  thereof. A rearward surface  438  of the edge molding  424  is provided with a rearwardly-extending flange  440 . The flange  440  preferably comprises an elongated member  442  provided with several reversely-angled resilient detents  444  which terminate in a conical surface  446  thereon. 
     The edge molding  424  is mounted to the receiving surface of the worksurface  24  defined by the peripheral groove  420  and vertical edge  422  by inserting the flange  440  on the rearward surface  338  of the edge molding  424  within the peripheral groove  420  until the rearward surface  438  of the edge molding  424  abuts the vertical edge  424  of the worksurface  24 . As the flange  440  is inserted within the peripheral groove  420 , the detents  444  on the flange  440  frictionally engage surfaces defining the peripheral groove  420 . The reverse angle of the detents  440  allow the flange  440  of the edge molding  424  to be inserted into the peripheral groove  420  with ease, however, if the edge molding  424  is attempted to be pulled out of the peripheral groove  420 , the detents  444  flex against the movement of the flange  440  out of the peripheral groove  420  making the removal of the edge molding  424  from its engagement with the worksurface  24  difficult. 
     FIG. 36 shows an alternative embodiment of the edge molding  448  provided with a flange  450  extending from a rearward surface  452  of the edge molding  448 . The flange  450  is preferably configured similarly to the flange  440  shown with respect to the first embodiment of the edge molding  424  of FIGS. 34-35. The edge molding  448  is mounted within a peripheral groove  420  of a worksurface  24  in the same manner and differs only in shape from the embodiment shown in FIGS. 34-35. The edge molding  448  is defined by a generally flat cross section which has rounded upper and lower edges  454  and  456  as shown in FIG.  36 . 
     FIGS. 37-39 show various embodiments of brackets  42  used to mount a worksurface  24  to a frame  14 . FIG. 37 shows a bracket  42  comprising a triangular body  460  having an upper leg and a vertical leg  462  and  464 , respectively, preferably disposed at right angles with respect to one another and a hypotenuse leg  466  extending between the distal ends thereof. The upper leg  462  and hypotenuse leg  466  are preferably provided with laterally-extending plates  468  provided for the purpose of increasing the structural integrity of the triangular body  460  and, in the case of the upper leg  462 , providing a mounting aperture  470  for receiving a fastener which extends through the mounting aperture  470  and into a worksurface  24 . Alternatively, an underside of a worksurface  24  can be provided with a depending flange sized to pass within the mounting aperture  470  when the worksurface  24  is placed thereon. 
     The vertical leg  464  is preferably provided with several angled hooks  472 , often referred to as vertical hanging intelligence, which are adapted to be received within the slots  76  the ramped portion  72  of a vertical rail  50  of a frame  14 . When the hooks  472  are mounted within the slots  72  of a vertical rail  50 , the triangular body  460  of the bracket  42  preferably extends in cantilever fashion from the vertical rail  50  of the frame  14  so that the upper leg  462  is positioned to receive a worksurface  24 . 
     FIG. 38 shows a second embodiment of the bracket  42  shown comprising an L-shaped body  474  adapted to wrap around a vertical edge of a tile  16 . The body  474  has a rearward edge  476  provided with several slots  478  configured in the same angled configuration as the hooks  472  of the embodiment of the bracket  42  shown in FIG.  37 . An upper edge  480  of the L-shaped body  474  is provided with a forwardly-extending plate  482 . 
     The plate  482  preferably extends in cantilever fashion from the upper edge  480  of the L-shaped body  474  and is provided with several mounting apertures  484 . As shown in FIG. 38, the mounting apertures  484  are adapted to receive fasteners  486  which extend through the apertures  484  into the worksurface  24  to securely mount the plate  482  to the underside of the worksurface  24 . The hooks  478  on the L-shaped body  474  are inserted within the slots  76  on a vertical rail  50  as described with the previous embodiments of the bracket  42  shown in FIG.  37 . 
     The advantage of the embodiment of the bracket  42  shown in FIG. 38 is that the L-shaped body  474  can rest directly upon a corner edge of the tile  16  whereby the mounting of a worksurface  24  (or any other office component) can be accomplished with a minimum of exposure of the bracket  42  to an occupant of the workspace definition system  10 . Rather, the L-shaped body  474  can be inserted through a seam between adjacent tiles  16  mounted to a frame  14  to engage the hooks  478  within the slots  76  on a corresponding vertical rail  50 . 
     A third embodiment of the bracket  42  is shown in FIG. 39 comprising a first portion  490  and a second portion  492  whereby the second portion  492  is adapted to be detachably mounted to the first portion  490  to allow the second portion  490  to be removed from engagement therewith. 
     The first portion  490  of the third embodiment of the bracket  42  comprises a plate  494  provided with a pair of raised channels  496  therein. The channels  496  are preferably oriented in a vertical direction and are adapted to receive a mating bracket of the second portion  492 . Each of the channels  496  defines a slot  498  which terminates at a lower end thereof in a stop  500  which delimits a lower limit of travel of the second portion  492  within each channel  496 . 
     The second portion  492  of the third embodiment of the bracket  42  shown in FIG. 39 comprises a plate  502  provided with several apertures  504  therein which are adapted to receive fasteners  506  for mounting the second portion  492  to the underside of a worksurface  24  as shown in FIG. 39. A rearward edge  508  of the plate  502  is provided with a pair of depending flanges  510  preferably aligned with the channels  496  on the first portion  490  of the bracket  42 . A depending central flange  512  is located between the depending flanges  510  and is preferably forwardly offset from a vertical plane of the depending flanges  510 . The central flange  512  is provided to abut the plate  494  of the first portion  490  of the bracket  42  to provide a more secure mounting of the second portion  492  to the first portion  490 . 
     The second portion  492  of the bracket  42 , when mounted to a worksurface  24  by the fasteners  506 , can be detachably mounted within the channels  496  of the first portion  490  by sliding the depending flanges  510  within the slots  498  within each channel  496  so that the offset central flange  512  abuts the plate  494  and prevents rotation of the second portion  492  with respect to the first portion  490  and also prevents bending of the flanges  510  and  512  as well. 
     The first portion  490  of the bracket  42  shown in FIG. 39 can be mounted to the frame  14  of the workspace definition system IO in several ways. Preferably, an upper edge  514  of the first portion  490  of the bracket  42  is provided with a hook  516  which is adapted to be passed over an upper edge of a tile  16  and engaged over an upper edge of a top, intermediate or foot rail  52 ,  54 , and  56 . Thus, as shown in FIG. 39, the first portion  490  can be removably mounted to the frame  14  between a pair of adjacent tiles  16  and the second portion  492  can be mounted to the first portion  490  to support a worksurface  24  in cantilever fashion with respect to a particular frame  14  within the workspace definition system  10 . 
     In any event, with respect to the bracket  42  shown in FIGS. 37-39, a worksurface  24  can have a distal end supported by a leg  26  as shown in FIGS. 1-2 to prevent undue strain or torsion imparted to the brackets  42 . However, it has been found that any of the brackets  42  shown in FIGS. 37-39 are adequate to support a worksurface  24  under normal use conditions of the workspace definition system  10 . 
     Referring back to FIGS. 1-3, the workspace definition system  10  can be laid out in any desired manner to further subdivide an open workspace area. It should be understood that the arrangement shown in FIGS. 1-3 is by example only and any particular configuration of the workspace definition system  10  shown in the drawings should not be construed as limiting. Rather, it is a feature of this invention that the workspace definition system  10  can be constructed and rearranged easily with a minimum of effort. 
     Further, as best shown in FIG. 2, electrical and data conduit  40  can be routed throughout the workspace definition system  10  such as by laying the electrical and data conduit  40  within the top, intermediate and foot rails  52 ,  54 , and  56 , respectively. Further, the electrical and data conduit  40  can be routed between various vertical levels of the interconnected frames  14  by passing the electrical data conduit  40  through the central apertures in the connectors  210  and trusses  252  as described above to further aid the routed of electrical and data conduit throughout the workspace definition system  10 . In addition, the vertical rails  50  of the frames  14  have several apertures therein for routing the electrical and data conduit laterally between interconnected frames  14 . Moreover, electrical and/or data conduit  40  can be accommodated in the open space of the frame  14  and can be routed using virtually any vector. 
     Various embodiments of the tile  16  can be easily mounted to the frames  14  interconnected by the connectors  210  to create a subdivided workspace as shown in FIG.  1 . The mounting of the tile  16  is affected by the first and second clips  300  and  302  as described above and as shown in FIGS. 28A-28C. 
     As best shown in FIG. 2, the interconnected frames  14  often have gaps between front and rear surfaces of a frame  14  and between adjacent tiles  14 . An upper surface of a frame  14  can be enclosed by a top cap  28  as described above while an upper surface of a joint between interconnected frames  14  can be enclosed by a corner cap  30  as previously described. Vertical gaps of a frame  14  can be enclosed by an end cap  32 . Office components, such as overhead bins  18 , shelves  20 , pedestals or file cabinets  22  and worksurfaces  24 , can be hung from the frame  14  to further increase the utility of the workspace definition system  10 . 
     For areas frequently accessed by the occupants of the workspace definition system  10  to access the electrical and data conduit  40  routed throughout the system  10 , removable or pivotal raceway covers  34  can be mounted on brackets  386  and be provided with openings  36  which communicate with electrical or data sockets (not shown) operably interconnected with the electrical and data conduit  40  routed throughout the system  10 . 
     It is readily apparent from a review of the specification and examination of the drawings that the workspace definition system  10  provides easy access to electrical and data conduit routed throughout the system  10  combined with easy reconfiguration and rearrangement of the layout of the system  10  with a minimum of cost and effort. 
     FIG. 40 shows an exploded perspective view of a filler panel assembly  522  having a top rail  52 , intermediate rail  54  and foot rail  56  extending in generally horizontal fashion between a pair of substantially vertical rails  50  so that the frame  14  has a generally rectangular configuration. The frame  14  is shown as also having a bump rail  58  with a ground engaging glide  200 , mounted to the base of a pair of vertical rails  50 , and a foot rail  56  to provide stability to the frame  14  and to support the frame  14  in a free-standing capacity on the floor surface  12 . The filler panel assembly  522  further includes a plurality of threaded rods  518  which extend generally parallel to the top rail  52 , the intermediate rail  54 , and the bottom rail  56 . The threaded rods  518  are secured, on one end, to a filler bump rail  520  by threaded apertures  524 . The filler bump rail  520  can be secured to a vertical surface by any one of a number of conventional fasteners  530 . A pair of base tile trim pieces  532  can be slidably secured to the distal edges of the filler bump rail  520 . It will be understood that the threaded rods  518  can be secured to any vertical surface having compatible threaded apertures to be secured thereto. The threaded rods  518  are also secured to the leading face  60  of one of the vertical rails  50 . Specifically, a portion of the threaded rods  518  extend through either one of the two mounting apertures  88 , which are fixed in position by a plurality of washers  526  and at least two nuts  528 . The distance between the vertical rail  50  and the filler bump rail  520  can be adjusted simply by rotating the nuts which secure the threaded rod  518  to the vertical rail  50 . Once the appropriate distance between the filler bump rail  520  and the vertical rail  50  is established, the tiles  16  can be cut down the a conforming width and secured onto the frame  14  in any one of a number of conventional manners specified here within. After the desired width has been achieved, a top cap  28  can be secured atop the top rail for aesthetic purposes. 
     FIG. 41 shows an exploded perspective view of a stackable filler panel assembly  534  mounted atop a frame  14  comprising rails  50 - 56  as previously described in FIG. 40 herein. The stackable filler panel assembly  534  is used to increase the height of a frame  14  of a filler panel assembly  522  when a framework of increased height is desired. The stackable filler panel assembly  522  comprises a pair of vertical rails  122  supporting a top rail  124  there between at an upper end thereof. Each of the vertical rails  122  are provided with a reduced diameter depending flange  126  which is preferably shaped to correspond with the interior of a vertical rail  50  as shown in FIG.  40 . The stackable filler panel assembly  534  further includes a plurality of threaded rods  518  which extend generally parallel to the top rail  52 , the intermediate rail  54 , and the bottom rail  56 . The threaded rods  518  are secured, on one end, to a filler bump rail stacker  536  by threaded apertures  524 . The filler bump rail stacker  536  can be secured to a vertical surface by any one of a number of conventional fasteners  530 . It will be understood that the threaded rod  518  can be secured to any vertical surface having compatible threaded apertures to be secured thereto. The threaded rods  518  are also secured by one of the vertical rails  126 . Specifically, a portion of the threaded rods  518  extend through either one of the two mounting apertures  88 , which arc fixed in position by a plurality of washers  526  and at least two nuts  528 . The distance between the vertical rail  122  and the filler bump rail  520  can be adjusted simply by rotating the nuts which secure the threaded rod  518  to the vertical rail  122 . Once the appropriate distance between the filler bump rail stacker  536  and the vertical rail  122  is established, the tiles  16  can be cut down the a conforming width and secured onto the frame  14  in any one of a number of conventional manners specified herewithin. After the desired width has been achieved, a top cap  28  can be secured on top of the top rail  124  for aesthetic purposes. 
     FIGS. 42A-H show how two frames  14  of the workspace definition system  10  can be interconnected in a perpendicular fashion intermediate the ends of each of the frames  14 . In particular, FIG. 42A shows the bump rail  58  of FIG. 16 with the addition of a bottom bracket  620  thereon for the interconnection of one frame intermediate the ends of an adjacent frame in a perpendicular fashion. A portion of the bottom bracket  620  is received in a bump rail aperture  636  of the bump rail  58 . The bottom bracket  620  is then secured to the bump rail  58  by fasteners  130 . 
     FIG. 42B shows the upper corner portion of a vertical rail  50  of a frame  14  highlighting the attachment of an upper bracket  622  thereto for completing the mid-panel installation of one frame to another. In particular, a threaded stud  626  of the upper bracket  622  is received by one of the mounting apertures  88  of the vertical rail  50 . The mounting apertures include a flow drill aperture  89  and a clearance aperture  91 . Subsequently, a nut  630  engages the threaded stud  626  to, in turn, secure the upper bracket  622  to the vertical rail  50  of the frame  14 . 
     FIG. 42C shows the placement of one frame  14  having the upper bracket  622  of FIG. 42B adjacent and perpendicular to another frame. In particular, the frame  14  without the upper bracket  622  is moved towards the frame  14  with the upper bracket  622 , so that the upper bracket  622  engages the frame rail groove  638  of the frame  14  without the upper bracket  622 . FIG. 42D shows a lower portion of the frame  14  highlighting the alignment and placement of the frame of FIG. 42C adjacent and perpendicular to another frame. 
     FIG. 42E is a fragmentary perspective view showing the mounting of a lower portion of the frame  14  intermediate the ends of an adjacent frame  14 . Once the bump rail  58  of the frame  14  with the bottom bracket  620  is operatively aligned and contacts the vertical rail  50  of the frame  14  without the bottom bracket  620 , both frames  14  are secured by a fastener is  130  through a first aperture  632  (shown in FIG. 42H) of the bottom bracket  620 . 
     FIG. 42F shows the completed mounting of an upper bracket of FIG. 42B over an upper portion of a vertical rail  50  of an adjacent frame  14 . After both frames  14  are operatively aligned, as shown in FIG. 42B, the upper bracket  622  is secured to the frame  14  using a pair of fasteners  130  which extend through a pair of apertures  634  (not shown). 
     FIG. 42G show the upper bracket  622  of FIGS. 42B,  42 C and  42 F highlighting the engagement portions for one frame and an adjacent frame in greater detail, including primary and secondary flanges  640  and  642 , respectively. FIG. 42H shows the bottom bracket  620  of FIGS. 42A,  42 D and  42 E highlighting the interconnecting portions for the adjacent frames in greater detail, as well as first and second apertures  632  and  634 , respectively. 
     FIG. 43A shows an upper, terminal portion of a frame  14  provided with a starter rail  650  adapted to interface with the vertical rail  652  and, in turn, with the frame of another workspace definition system, such as those commercially available from Trendway Corporation, and which comprise a series of frames interconnected in a manner similar to that described herein. To secure a frame  14  of the present invention to a prior art frame, a connector  210  (as shown in FIG. 17) can be used to secure the vertical rail  50  to a starter rail  650  at a complementary angle. The starter rail  650  can be then aligned with the vertical rail  652  of the prior art system as shown in FIG.  431 B. Once both the starter rail  650  and the prior art vertical rail  652  are aligned, a living hinge  658  is slidably mounted to channels  654  and  656 , respectively. FIG. 43C is provided merely for illustrative purposes and shows an enlarged cross-sectional view of the starter rail  650  of FIGS. 43A-43B for providing a secure mounting between the frame of the workspace definition system described herein and the prior art workspace definition system. 
     FIGS. 44A-E show an intermediate (non-terminal) interconnection of a frame  14  in accordance with the present invention to the terminal end of a prior art frame. In particular, FIG. 44A shows a top bracket  670  which is sliding mounted onto the upper portion of a vertical rail  652  and, in turn, a frame of a prior art workspace definition system. FIG. 44B shows the top bracket  670  mounted to the vertical rail  652  of the prior art workspace definition system perpendicular and adjacent to the frame  14  of the workspace definition system of the invention described herein. As can be seen in FIG. 44C, once top bracket  670  is mounted on the top rail  52  of the present invention, the bracket  670  is secured thereto by a pair of fasteners  130 . After the top bracket is secured, a bottom bracket  672 , which is mounted to the bump rail  58 , is placed adjacent to a glide  674  of the prior art frame . As shown in FIG. 44E, the bottom bracket  672  is then received over the glide  674  of the prior art workspace definition system and secured thereto by a pair of fasteners  130 . 
     When electrical and/or data conduit  40  is received from an elevated resource, such as a ceiling, a power pole can be integrated into the workspace definition system for both safety and aesthetic purposes. As shown in FIG. 45A, a power pole  800  can extend between a ceiling surface  801  and a top rail  52  of the workspace definition system  10  described herein and interconnected thereto by a short bracket  802  and a long bracket  804 . As shown in FIG. 45B a two-piece trim cover  806  can be used to conceal the interface between the power pole  800  of FIG.  45 A and the ceiling surface  801 . The two-piece cover  806  includes an aperture region  812  for accommodating electrical and/or data conduit  40 . The two-piece cover  806  has a pair of tabs  810  that are lockably received in a pair of slots  808 . 
     FIG. 45C shows the power pole  800  of FIG. 45A comprising a C-shaped channel and a snap-fit cover  816  for mounting thereto and also showing an interconnection of the short and long brackets  802  and  804  respectively, which are secured by fasteners  130  to a lower portion thereof. 
     FIG. 45D shows a top cap  814  (similar to that in FIG. 13) provided with a recessed region  817 , which is adapted to accommodate a lower portion of the power pole  800  of FIGS. 45A-45C to conceal the interface between the power pole  800  and the frame  14  of the workspace definition system  10 . 
     While particular embodiments of the invention have been shown, it will be understood, of course, that the invention is not limited thereto since modifications may be made by those skilled in the art, particularly in light of the foregoing teachings. Reasonable variation and modification are possible within the scope of the foregoing disclosure of the invention without departing from the spirit of the invention.
