Title: Wall panel with off-module components

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application No. 60/201,473, filed May 3, 2000, which application is hereby incorporated herein by reference. 
    
    
     BACKGROUND 
     The present invention relates generally to a wall panel system, and in particular, to a wall panel comprising an off-module component disposed thereon. 
     Panel systems are commonly used to divide large, open office space into separate workspaces. For example, Herman Miller, Inc., the assignee of the present application, manufacturers and sells at least two such work space management systems: the ACTION OFFICE® system and the ETHOSPACE® system. Typically, workspace management systems are comprised of a series of wall panels arranged in various configurations. For example, wall panels can be connected in series in an end-to-end configuration, or they can be arranged around and connected to a corner post in a two-way, three-way or four-way configuration. 
     Typically, office system components, such as return panels, overhead cabinets, work surfaces, shelving and the like, are supported at the junction of adjoining wall panels, whether by way of direct connection to the ends of one or more of the adjoining wall panels, or by way of connection to a corner post or other connector positioned therebetween. As such, the position of the components is predetermined, based upon the modular length of the wall panels incorporated into the system. 
     However, wall panels also can be configured to support various office system components “off-module,” meaning that the various office system components, e.g., return panels and the like, can be connected to the wall panel at various points along the length of the wall panel between the ends thereof. Typically, however, such wall panels include elaborate, complex infrastructures that can be expensive to manufacture. In addition, such wall panels typically have points of attachment vertically fixed along the height of the panel, thereby limiting vertical reconfigurability of the components. Moreover, such systems typically require at least two points of attachment to prevent the inadvertent dislodgment of the components from the wall panel. 
     SUMMARY 
     Briefly stated, one aspect of the invention is directed to an improved wall panel assembly comprising first and second upwardly extending, curvilinear walls, which are spaced apart to form an upwardly opening channel. A support member includes a downwardly extending, curvilinear insert portion, which is dimensioned to be received in the channel. The insert portion is inserted into the channel, and a component is attached to the support member. In a preferred embodiment, a rail member defines the channel and is attached to a wall panel frame. The rail is preferably removably attached to the wall on one or both sides thereof. 
     In one embodiment of the invention, the only connection between the component and the wall panel is the interface between the insert portion of the support member and the channel. In one preferred embodiment, the insert portion and the channel include opposing channels that form a passage therebetween. A pin can be inserted in the passageway so as to prevent dislodgment of the insert portion from the channel. 
     In another aspect of the invention, the wall panel comprises a downwardly extending wall having a bottom edge and an upwardly extending wall having a top edge. The downwardly extending wall is disposed above the upwardly extending wall, with the bottom and top edges respectively of the downwardly and upwardly extending walls spaced apart to form an opening therebetween. A second support member includes an insert portion that abuttingly engages at least one of the downwardly and upwardly extending walls. The component is attached to the first support member engaging the channel, and is further attached to the second support member. In a preferred embodiment, a connector tile comprises the downwardly and upwardly extending walls and is attached to a wall panel frame. 
     In yet another aspect of the invention, the wall panel assembly comprises an elongated, horizontally oriented channel. A support member engages the channel, and can be moved to any position along the length of the channel. 
     In yet another aspect, the support member comprises a rotatable cam member that is rotatable between an engaged position and a disengaged position. The cam member is inserted into an opening in the component when in the disengaged position and is thereafter rotated to the engaged position so as to engage the component. 
     In yet another aspect of the invention, a method for reconfiguring a wall panel with an off-module component is provided. The method includes providing a panel having a first and second side and attaching a rail member to the first side of the wall panel. The rail member comprises a curved, upwardly opening channel. The method further includes providing a support member having a downwardly extending, curved insert portion. The insert portion is inserted into the channel and a component is supported on the support member. 
     In another aspect, the method further comprises disconnecting the support member by removing the insert portion from the channel and detaching the rail from the wall panel. 
     The present invention provides significant advantages over other wall panel assemblies. For example, the interface between the insert portion of the support member and the curved channel of the wall panel can help prevent the support member from being inadvertently dislodged from the wall panel, especially when configured with an antidislodgment pin. As such, various components, such as an overhead cabinet, can be connected to the wall panel at a single location, without the need for additional anti-dislodgment clips and the like. 
     At the same time, the component can be further connected to a second support member engaged with a pair of walls forming an opening therebetween. The support members can be easily moved to any position along the length of the wall panel to provide off-module support for various office system or work station components. 
     In addition, the rail member, which is preferably removably attached to a frame of the wall panel, can be easily attached to the frame as needed to support various off-module components. At the same time, the rail member can be easily removed if no components are to be attached off-module. As such, the user can use the rail member as needed, thereby reducing the inventory of parts and the overall expense of the system. 
     Likewise, the connector tile, which also is preferably removeable, can be easily attached or removed as needed. In addition, both the rail member and connector tile can be attached to the wall panel at any vertical location, thereby providing a variety of vertical support positions for the various office system components. 
    
    
     The present invention, together with further objects and advantages, will be best understood by reference to the following detailed description taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS 
     Referring to the drawings, FIG. 18 shows a wall panel frame  100 . The frame  100  comprises a pair of vertical frame members  102  and an upper and lower horizontal frame member  104 . The horizontal frame members  104  abut the vertical frame members  102  and are preferably affixed thereto at the corners of the panel by welding. It should be understood that the frame members could also be affixed by way of fasteners, adhesives and the like. The vertical frame members  102  have a slightly larger width than the horizontal frame members  104 , and further include an outwardly facing channel  105  formed along the length thereof on each end of the wall panel. The vertical frame members have a plurality of openings  103 , or slots, formed along their respective lengths at the opposite ends of the panel. The openings  103  are shaped and oriented to engage brackets, which support various work station components. As shown in FIGS. 3,  9 ,  18  and  27 , the vertical frame members  102  further include a plurality of vertically disposed alternating rectangular openings  118  and tapered keyhole slots  120 , which are positioned on the frame members inboard of the openings  103 . The vertical frame members  102  further include a plurality of circular fastener openings  122  vertically disposed therealong. 
     As best shown in FIGS. 9,  19 ,  20  and  27  cover tiles  114  span between and are removeably attached to the vertical frame members  102  with hooks  118  and spring clips  116  that engage the frame members at openings  118 ,  120 . The cover tiles  114  do not span the entire length of the wall panel, but fall short to expose the openings  103  on the vertical frame members such that various components can be engaged thereon. The cover tiles  114  can be covered with a covering such as a fabric, can comprise a tackable surface, or can be made of metal, wood, plastic, glass or any other suitable material. The cover tiles  114  further preferably include a trim portion  115  extending from the bottom of the cover tile, which spans the gap between the bottom of the cover tile and the top of the next lower tile. The trim portion is preferably vinyl. 
     Alternatively, a rail tile can be removeably attached to the frame in place of the cover tile. The rail tile includes a plurality of horizontally oriented channels disposed one above the other. Various office system components, such as paper trays and the like, include a hook member that is engaged with at least one of the channels on the rail tile. The back of the member abuttingly engages the outermost face of the rail tile for stability. 
     As shown in FIG. 18, the wall panel further includes a top cap  124  that is snap fitted to the upper horizontal frame member with a pair of clips. A pair of base covers  126  are connected to opposite sides of a lower portion of the frame. A pair of support feet  128  engage the floor and support the frame thereabove. 
     Serially-adjacent wall panels are connected one to the other with a draw tube assembly  106  shown in FIG.  18 . In particular, the draw tube  106  is disposed in the space formed by the channels  105  of abutting, adjacent vertical frame members  102 . A draw block  108  extends into one of a series of openings  130  formed in the base of channel  105  and engage draw surfaces formed on a plate installed on top of the vertical frame members. A draw bolt  110  engages the draw block and draws the adjacent panels together. Wall panels connected at 90 degrees in two-way, three-way and four-way configurations further incorporate a corner post disposed between the various wall panel configurations. The wall panel frame, connector system and tiles are further shown and described in U.S. Pat. Nos. 4,571,907, 4,876,835 and 4,618,192, all of which are hereby incorporated herein by reference. 
     Now referring to FIGS. 1-3, a rail member  2  includes an upper portion  3  and a lower portion  5 . The upper portion  3  includes an upwardly opening channel  8  formed by a first and second upwardly extending walls  6 ,  7 . The upstanding walls  6 ,  7  of the rail member are curvilinear, and preferably arcuate, such that the channel  8  has a curved interior space formed between an inner concave surface  9  of the first wail and the inner convex surface  11  of the second wall. In an alternative embodiment, shown in FIG. 22, the first wall  6  has a return portion  300  of flange that extends laterally inward to close the gap between the wall and the top cap of the wall panel. The lower portion  5  of the rail member includes a vertically extending wall  50 , with a plurality of horizontally extending recesses  52 , one being formed as a groove, that are recessed laterally inward from the outermost surface of the vertical wall. A plurality of ribs  54  extend laterally from the wall opposite the recesses  52  so as to provide the rail member with increased strength. At the same time, a plurality of laterally extending openings  302  are centered in the recesses and communicate with a channel  304  formed by the ribs. 
     The ends of the rail  2  are attached to one side of the vertical frame members  102  making up the inner panel frame  100  with a plurality of fasteners, such that the channel  8  runs horizontally along a top edge of the wall panel. In this way, the rail member  2  can be removeably attached to the frame and can be removed or installed as needed. As shown in FIG. 3, The fastener heads  56  are received in the recessed grooves such that they do not interfere with any support components or the like which abut the outermost surface of the vertical wall. It should be understood that the rail member could also be attached to the horizontal frame member with fasteners, and that the rail member could be attached to any of the frame members with clips and the like. Alternatively, the rail member could be fixedly attached to the frame by welding and the like. 
     The upwardly opening channel  8  of the rail member runs substantially along the entire length of the wall panel, but terminates short of the ends of the frame so as to leave exposed the slots  103  formed in the vertical frame member  102 . The inner, first wall  6  of the channel is longer than and has a greater upward extent than the outer, second wall  7 . The channel  8  curves away from the frame as it extends upwardly. The concave interior surface  9  of the inner wall, faces outwardly from the panel frame, while the convex interior surface  11  of the outer wall faces inwardly toward the panel frame. The rail member is preferably metal and is preferably formed as an extrusion, although it should be understood that other materials and methods of forming would also work. 
     A cover tile  4 , shown in FIGS. 1,  3  and  4 , is positioned over the rail member  2  and is removeably attached to the vertical frame members with hooks and clips which are inserted in a pair of mounting flanges  60 , as explained above. The cover tile has side portions  58  or webs that extend between the mounting flanges  60  and a flat outer face  62  of the cover tiles. Each side portion  58  has a cut-out  12  along a top portion thereof. As shown in FIGS. 1 and 3, the cut-out  12  is dimensioned to allow access to the ends of the channel  8  once the cover tile  4  is mounted to the frame such that various support members can be slid from one panel to the next, when serially aligned. The cut-out can be formed in a variety of different shapes. For example, the cut-out  12  is shown in FIG. 3 as being substantially rectangular, with the corners thereof being curved. Alternatively, as shown in FIG. 21, the corners of the side portions  58  can simply be cut at a diagonal to form a triangular shaped cut-out  312 . Also in the embodiment of FIG. 21, a pair of hat-sections  314  are attached, preferably by welding, to the backside of the cover tile  4  to provide it with additional strength and rigidity. 
     When mounted to the frame, the cover tile  4  covers the lower portion  5  of the rail member, as shown in FIGS. 1,  3  and  5 , and further covers substantially the entirety of the outer wall  7  such that only a lip  62  thereof is visible to the user. If the rail member is not needed for off-module support, it can be removed after the cover tile  4  is removed. A cover tile  114 , with its closed upper end and sides, can then be removably attached in place of the cover tile  4 . 
     Referring to FIGS. 5-7 and  14 , a vertically extending, upper support member  14  includes an insert portion  18 , preferably configured as a curved hook shaped to be received in the channel, and a vertical extending connector portion  64 . The insert portion  18  is formed by folding a metal flange back on itself to increase the rigidity and strength thereof. The insert portion  18  preferably has a radius of curvature of about 1.25 inches. The insert portion  18  is inserted into the channel  8 , such that the base portion  66  of the connector portion abuts the surface of the outer tile face. The interface between the curved insert portion  18  and the curved channel  8  prevents unintended dislodgment of the support member and of any components supported thereon. 
     The connector portion  64  of the support member includes a web  68  extending laterally from the base portion  66  and a plurality of flanges  70  extending from the web to form a series of channels along the length of the connector portion. The connector portion channel is attached to an end of a work station component, such as an overhead storage cabinet. For example, as shown in the alternative embodiment of FIGS. 31-33, an end wall  316  of an overhead end panel  318  is received in the channel and is secured to the flange with a snap-fit configuration. Alternatively, fasteners and the like can be used to secure the connector portion to the end panel. A pair of openings  328  are formed in the base portion  66  and are positioned to secure a pair of cross-braces  320  that extend from one connector member to another, as shown in FIG.  36 . The end panels  318  further support a shelf  322 . If desired, a flipper door assembly (not shown) can be installed so as to form an overhead cabinet with the end panels and shelf. In an alternative embodiment, the end panels can be configured with a standard bracket that engages the slots in the vertical frame member. 
     In an alternative embodiment, shown in FIGS. 5,  6  and  16 , an upper support member  80  is configured to engage a return panel  20 . In this embodiment, the support member includes an insert member  82 , best shown in FIG. 28, having a curved flange  84  dimensioned to be received in the channel  8  and a horizontally extending mounting flange  86  having a pair of holes. An L-shaped connector member  88  includes a horizontal mounting flange  90  that is attached to the mounting flange  86  of the insert member with fasteners, or by welding and the like. A vertically extending connector flange  92  includes an alignment block  94  mounted thereon. The block  94  is dimensioned to be received in the channel  116  formed in the vertical frame member along the end of the return panel, and further to extend into an opening formed in the end of the vertical frame member in the base of the channel. 
     A cam member  96  is rotatably mounted to the block  94  about a horizontal axis of rotation, and includes a pair of shoulders  97  at opposite corners of the cam member. A pair of stop members  98  extends laterally from the block  94  and is positioned to engage the shoulders  97  of the cam member  96  when it is rotated to a disengaged position. The support member, with the cam member, is attached to work station component to the wall panel. For example the cam member  96  can be positioned to be aligned with and extend into the opening  130  formed in the end of a vertical frame member of a return panel as shown in FIG.  5 . The return panel has the same construction as the wall panel. 
     Once the cam member  96  is disposed through the opening, the installer rotates the cam member  96  from a vertically oriented disengaged position to a horizontally oriented engaged position, as explained in more detail below. A backside of the cam member  96  engages the inner surface of the vertical frame when the cam member is in the engaged position so as to releasably secure the return panel, or other work station component, to the support member. 
     In an alternative embodiment, shown in FIG. 33, the insert member  82  is attached beneath a flange  324  extending laterally from the top of the base portion  66  of the connector  326 . The flange  324  is formed by folding the flange back on itself. The flange  324  of the connector member is attached to the flange  86  with a pair of fasteners. Preferably, the connector is first attached to the end panel  318 , or other component, and is thereafter moved into position over the insert member  82  and attached thereto with the fasteners. 
     In yet another alternative embodiment, best shown in FIGS. 36 and 37, the insert member  82  further includes a groove or channel  500  formed along its length at the corner at the junction between the flanges  84  and the flange  86 . The rail member includes a groove or channel  502  formed along the length of the wall  6 . As shown in FIG. 37, the groove on the insert member mates with the opposite facing groove on the wall so as to form a cylindrical passageway  506 . An anti-dislodgement pin  504  is inserted into the passageway  506  so as to prevent the insert member  82  from being vertically displaced, or removed from the rail member channel  8 . It should be understood that the pin  504  does not prevent the support member, and the insert member in particular, from being moved horizontally along the length of the channel  8 , if desired. It also should be understood that any of the above-described insert members and insert portions, along with the rail members, can be configured with grooves to form a passageway shaped to receive a pin when mated. Although the passageway has been shown as cylindrical, it should be understood that other shapes, including a rectangular cross-sectional opening, would also work. 
     In yet another embodiment of the support member, shown in FIGS. 5 and 15, the connector member and block member are elongated to form a change-of-height (COH) connector  16 , which extends down to and accommodates a shorter return wall panel being attached to a taller base wall panel. Other than their length or size, the components for the COH support member are of the same type of construction as the support member  80 , and the same reference numbers are therefore used to identify like components. 
     In yet another embodiment of the support member, shown in FIG. 25, the connector member  350  is elongated and includes three support platforms  352  spaced longitudinally along the length of the connector member and attached thereto with fasteners, such as rivets, or by welding and the like. Each support platform  352  includes a support surface  354  having an opening  356  formed therein that is aligned with an opening formed in the connector member. Each support platform further includes a pair of stop members  358  extending laterally from opposite diagonal corners thereof. The connector member further includes raised portions  360 , or stiffening ribs formed therein for added rigidity and strength. Each raised portion has an opening  362  formed therein. The opening  362  is shaped to receive a tab member that extends from the vertical frame member along the end of the wall panel. In this way, the tab member does not interfere with the installation of the connector member on the return panel as the rib portion is received in the outwardly facing channel  105  formed along the length of the vertical frame member  102 . Although the connector member is shown in FIG. 25 with three support platforms, it should be understood that it could also be configured with any other number of such platforms as desired. 
     In one preferred embodiment, a cam member  96  is rotatably mounted to each support platform as needed to secure the connector member to a return panel or other component. For example, the cam member can be secured to one of the three support platforms as needed to accommodate return panels of various heights. Or, a plurality of cam members can be used to secure a single component. Preferably, the cam member  96  is mounted with a fastener, such as a screw, that extends from the back side of the connector member through web  92 , through the opening  356  and threadably engages the cam member  96 . 
     During installation, the installer can slide the support member  14 ,  80 ,  16  to any position along the length of the rail member  2 , thereby providing the user with infinite off-module adjustment capability for the various office system, or work station components. It should be understood that the term “component” means any office system item that is attached to or supported on a wall panel, including for example, but not limited to, return panels, overhead storage units, shelving, worksurface members, various support brackets and various tools, including for example paper trays and the like. 
     Referring to FIG. 5, the portions of the channel  8  remaining open between the various support members  14 ,  16 ,  80  that are inserted therein can be covered with a channel cover member  22 , best shown in FIGS. 5 and 8. The cover member includes a curved insert portion  24  that is shaped to be received in the channel, and a horizontal and vertical flange  26 ,  28 . The vertical flange  28  forms a channel  29  with the insert portion  24  that is shaped to receive the upper edge  62  of the outer wall  7 . The bottom edge  27  of the vertical flange is disposed adjacent the top edge of the cover tile  4  so as to provide a pleasing aesthetic appearance. The horizontal flange  26  extends inwardly to abut an upper portion of the inner wall. The cover member  22  can be made of plastic, wood or metal, and is preferably formed as an extrusion. 
     In a preferred sequence of installation, best illustrated in FIGS. 26 and 27, the connector member  350 ,  80  is first attached to the return panel, or other component. In particular, the cam members  96  are first loosened so as to be spaced from the connector member or support platform by unscrewing the fastener threadably engaged with the cam member as it engages the stop members. The connector member is then positioned at the end of the return panel such that the cam member extends through the opening  130 . The fastener is then tightened so as to both rotate the cam member  96  and also to draw it towards the connector member wherein the frame member  102  is clamped between the cam member  96  and the connector member. The cam member  96  engages the inner walls of the frame member to prevent the cam member from spinning inside the frame member and thereby allow it to be drawn towards the connector member. This operation is repeated for each cam member along the length of the connector member. It should be understood that only one cam member is required to secure the connector to the component. 
     Once the connector member is securely attached to the return panel, or other component, the return panel is positioned adjacent the wall panel such that flange  90  is disposed above the flange  86  of the insert member  82 , which is positioned at a desired position along the length of the rail member and engaged therewith as described above, and preferably with an anti-dislodgment pin. The connector member is then secured to the insert member to complete the installation. 
     In another aspect of the off-module components, best shown in FIGS. 9,  11  and  17 , a connector tile  30  is attached to the panel frame. The connector tile  30  is preferably the same size as the cover tile  114 . In this way, the wall panel can be reconfigured for off-module support by removing one or more cover tiles  114 , and removably attaching in their place one or more connector tiles  30 . Preferably, the connector tile  30  is removeably attached to the vertical frame members  102  with a plurality of fasteners, such as screws. Alternatively, the connector tile can be fixedly attached to the frame with clips and hooks, or by welding or the like. It should be understood that the rail member and one or more connector tiles can be attached to one or both sides of the frame as needed for off-module attachment. 
     The connector tile  30  includes a plurality of horizontal T-shaped members  32  extending laterally from an outer side wall  38 . The connector tile further includes an inner side wall  39  laterally spaced from said outer wall and connected thereto with spaced webs  37  to form a plurality of box-beams. The T-shaped members  32  each include a base wall  140 , a wall  142  extending upwardly from the base wall and terminating in a top edge  146  and a wall  144  extending downwardly from the base wall and terminating in a bottom edge  148 . The top edge  146  of the upwardly extending wall  142  of a lower T-shaped member and the bottom edge  148  of the downwardly extending wall  144  of an upper T-shaped member are spaced apart to form an opening  150  therebetween. The walls  140 ,  142 ,  144 ,  38  form T-shaped channels  34  therebetween. An upper and lower L-shaped member  152 ,  154  run along the top and bottom of the tile and include a downwardly and upwardly extending wall  156 ,  158  respectively. In a preferred embodiment, shown in FIG. 23, the end portions of the downwardly extending walls are cut away so as to provide additional access to the channels. 
     The connector tile  30  is preferably made of metal and is formed by extrusion. In the embodiment shown in FIG. 17, two pairs of horizontally elongated flanges  160  extend from the inner wall  39  of the connector tile. Each pair includes an upper and lower flange angled toward each other. The flanges are configured to capture a piece of angle iron that provides increased strength and rigidity to the connector tile. 
     A lower support member  162  includes a T-shaped support block  36 , or insert member, best shown in FIG. 10, and a connector bracket  40 , best shown in FIGS. 12 and 13. The support block  36  has a middle portion  164  and a pair of wing portions  166  or insert portions, extending therefrom to form a cross-section shaped to mate with the channel  34  formed on the connector tile. Preferably, the wing portions  166  have an outermost surface  168  that is curved or angled to engage the correspondingly shaped walls  142 ,  144  on the connector tile  30 . The support block  36  is slid into the T-shaped channel, with an upper wing portion  166  of the support block engaging the downwardly extending wall  144  of an upper T-shaped member  32  and with a lower wing portion  166  of the block engaging an upwardly extending wall  142  of a lower T-shaped member  32 . The middle portion  164  of the support block extends through the opening  150  formed between the two walls  142 ,  144  and has a plurality of threaded holes  176 . 
     In an alternative embodiment of the support block, shown in FIG. 29, the corners  163  of the support block are curved so as to facilitate the insertion of the block in to the channel  34 . 
     If the support block  36  is inserted into the uppermost or lowermost T-shaped channel  34 , the upper or lower wing portion, respectively, of the support block will engage one of the walls  156 ,  158  of the upper or lower L-shaped member  152 ,  154 . The support block is preferably made of metal. The support blocks, which must be slid into the channels  34  from the end of the connector tile, cannot be laterally removed from the connector tile and act as an anti-dislodgment member once they are connected to a work station component. 
     Referring to FIG. 12, the connector bracket  40  includes a T-shaped plate member  170  having an alignment block  94  attached thereto, or formed therein by stamping or the like. A cam member  96  is rotatably attached to the alignment block  94  and a pair of stop members  98  extend laterally from the block  94  to stop the rotation of the cam member  96  at a disengaged position. An upper portion  172  of the plate member includes a plurality of horizontally spaced fastener holes  174  spaced to mate with the holes  176  disposed in the support block. A plurality of fasteners is installed to attach the connector member to the support block. 
     Referring to FIG. 13, an alternative embodiment of the plate member  178  includes a plurality of horizontally spaced and vertically spaced openings  182  formed in an upper portion  180  that are positioned to be aligned with the openings  176  in a pair of support blocks inserted in a connector tile and positioned one over the other. This double attachment provides additional strength and security. 
     In yet another alternative embodiment of the connector bracket, best shown in FIGS. 24,  26  and  27 , the connector bracket  600  is preferably T-shaped, and has a longitudinally extending hat section  602  that is shaped to be received in the end of the return panel. A pair of wing portions  604  each have a curved portion  606 , which form recesses that are shaped to mate with the outermost surface of the T-shaped members  32  of the connector tile. The curved portions also provide additional strength for the bracket. The wing portions  604  each include a pair of holes  608  for receiving a fastener or the like. 
     The bracket  600  is preferably made as a stamping. A pair of stop members  610  extend laterally from a lower portion of the hat section. A cam member  96  is rotatably mounted to the connector bracket with a fastener that extends through the hat section and threadably engages the cam member. The stop members  610  engage the cam member when it is in the disengaged position so as to allow it to be loosened. 
     Once installed, the lower support member  162  can be positioned to engage an office system component, such as the return panel shown in FIG.  9 . The return panel can be attached to both the rail member and the connector tile using the cam members  96  of the upper and lower support members respectively, as shown for example in FIGS. 26 and 27. Again, the lower support member  162 , and the support block in particular, along with any components attached thereto, can be slid in the channels  34  of the connector tile along the length thereof to provide infinite off-module support locations for the components. Preferably, the connector bracket  600  is first attached to the return panel, or other component, as explained above. The return panel is then placed adjacent the wall panel. The wing portions  604  extend laterally from each side of the return panel frame such that the holes  608  therein can be accessed by the installer. Fasteners are then installed to secure the connector bracket  600  to the support block  36  to complete the installation. 
     Alternatively, as shown in FIGS. 11 and 30, the support member can be comprised solely of the support block  36 , one or more of which can be positioned in the channels  34  and of the connector tile and can be fastened to a work station component such as the work-surface support bracket  38  shown in FIGS. 11 and 30. In particular, one support bracket  188  is engaged in the slots of the vertical frame member, while the other support bracket  38  are bolted directly to one or more vertically disposed support blocks  36  inserted into the channels  34  of the connector tile  30 , without the need for the connector bracket. Alternatively, the support brackets can be configured with hook members that engage one or more of the walls of the connector tile, or they may be provided with integrally formed blocks that can be inserted into the channels. 
     Finally, as best shown in FIG. 35, a work surface support  620  also can be connected off-module. In the assembly, a connector bracket  622  is configured as a channel  624  having a base web  626  and opposite mounting flanges  628 ,  630 . A first flange  628  is connected to one or more support blocks  36  engaged with a connector tile  30 , and preferably two support blocks positioned adjacent the top of the connector bracket  622 , as explained above. The opposite second flange  630  is connected to the end of the work surface support panel  632 , preferably with a plurality of fasteners  634 . It should be understood by one of skill in the art that the connector bracket could be formed integrally as part of the support panel, or that the support panel could comprise a mounting flange having openings aligned with various support blocks. The support panel further comprises a bottom portion  640  and a leg  642  that supports the outboard end of the panel. 
     Although the present invention has been described with reference to preferred embodiments, those skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention. As such, it is intended that the foregoing detailed description be regarded as illustrative rather than limiting and that it is the appended claims, including all equivalents thereof, which are intended to define the scope of the invention.
