     For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in  FIG. 1 . However, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
     The reference numeral  1  ( FIG. 1 ) generally designates a table assembly of the present invention that includes a frame  2  which supports two or more elongate worksurfaces  3 ,  4  on opposite sides of the table  1 . Although the illustrated example includes two worksurfaces  3 ,  4 , it is noted that certain aspects of the present invention may also be utilized with a single worksurface. Each worksurface  3 ,  4  is of sufficient length to form multiple workstations arranged in a side-by-side relationship, which can be accessed anywhere along the outer edges of worksurfaces  3 ,  4 . The worksurfaces  3 ,  4  can be unitary members or sectioned members as needed. The table assembly may also include wire management panels that are configured to be supported near the interior edges of the worksurfaces  3 ,  4  at a centrally disposed elongate open window  5  defined by the frame  2 . The wire management panels, or troughs, are used to route cable, data, power and the like to the different workstations along the length of the table  1 . Preferably, the wire management panels  7  are constructed of a metal such as steel, however, other materials may also be utilized, such as other metals, wood, fabrics and knits, and the like, or some combination thereof. 
     The illustrated frame  2  ( FIG. 2 ) includes a support arrangement including a pair of end leg assemblies  6 ,  8 , and a center leg assembly  10 . It is contemplated that the frame  2  may include any plurality of leg assemblies as needed to support the table  1 . The end leg assemblies  6 ,  8  are interconnected at opposite ends of first and second sets  12 ,  14  of parallel, elongate hollow beams  16 ,  17 ,  18 ,  19 , wherein the beams  16 ,  17  define the first set of beams  12 , and the beams  18 ,  19  define the second set of the beams  14 . Multiple sets of beams  12 ,  14  and leg assemblies may be used to provide a table with an extended length. The beams  16 - 19  of the first and second sets of beams  12 ,  14  are spaced laterally apart a predetermined distance and are generally parallel with one another along the length of the table  1  to define the elongate open window  5  in conjunction with the end leg assemblies  6 ,  8 . As shown in  FIG. 2 , the beam  16  and the beam  18  are interconnected and linearly aligned. Similarly, the beam  17  and the beam  19  are interconnected and linearly aligned. Innermost ends  16   a - 19   a  of the beams  16 - 19 , respectively, are coupled to the center leg assembly  10 , as further described below. Outermost ends  16   b - 19   b  of the beams  16 - 19 , respectively, are coupled to one of the associated end leg assemblies  6 ,  8 , as further described below. A plurality of cantilevered support brackets  15  are coupled to the frame  2  along outer surfaces of the beams  16 - 19 , and the worksurfaces  3 ,  4  ( FIG. 1 ). End brackets  15   a  are similar to the top support brackets  15 , and are coupled to the end leg assemblies  6 ,  8  for further supporting the worksurfaces  3 ,  4 . The end leg assemblies  6 ,  8  are substantially identical in configuration to one another, and will be described below with reference to end leg assembly  6  shown in  FIG. 3 . 
     The end leg assembly  6  ( FIG. 3 ) includes a pair of opposed first and second legs  20 ,  22 . In the illustrated example, the first and second legs  20 ,  22  comprise cast aluminum members having adjustable lower ends  20   b ,  22   b , respectively, although other materials such as wood, plastics and the like may be utilized. The lower ends  20   b ,  22   b  are adapted for abutting support on an associated floor surface. The first and second legs  20 ,  22  further include upper ends  20   a ,  22   a , connected to opposing end support brackets  24 ,  26  via mechanical fasteners such as screws or bolts (not shown). A horizontal leg beam  30  extends between the pair of first and second legs  20 ,  22  and includes opposite ends  32 ,  34  thereof connected with the end support brackets  24 ,  26  by additional mechanical fasteners. As further shown in  FIG. 3 , the end supports  15   a  are coupled to the end support brackets  24 ,  26 , and extend outwardly from the first and second legs  20 ,  22  for supporting a worksurface as noted above. In  FIG. 3 , a pair of bracket covers  24   a ,  26   a  are shown exploded away from the end support brackets  24 ,  26 , and are used to cover the support brackets  24 ,  26  in assembly. Each end leg assembly  6 ,  8  has a generally inverted U-shaped side elevational configuration, and is sufficiently rigid to support the worksurfaces  3 ,  4  ( FIG. 1 ), as well as any objects placed thereon. 
     The center leg assembly  10  ( FIGS. 4A-4D ) is shown having a pair of opposed first and second legs  42 ,  44 . The first and second legs  42 ,  44 , like first and second legs  20 ,  22  described above, are contemplated to be cast aluminum members, however, other suitable materials may be utilized. The first and second legs  42 ,  44  each include upper ends  42   a ,  44   a , which are respectively connected to beam connecting bracket assemblies  50 ,  52  by fasteners  54 , and adjustable lower ends  42   b ,  44   b , respectively, which are adapted for abutting support from an associated floor surface. 
     The beam connecting bracket assemblies  50 ,  52  define linear beam interconnecting bracket assemblies, as further described below. A substantially horizontal trough support bracket  56  couples to and extends between the first and second legs  42 ,  44  and includes opposite end plates  58 ,  60 . The end plates  58 ,  60  are operably coupled to the beam connecting bracket assemblies  50 ,  52  at connecting locations X, which may include welded connections between the component parts. As shown in  FIGS. 4A-4D , the center leg assembly  10  has a generally inverted U-shaped side elevational configuration similar to the end leg assemblies  6  and  8  ( FIG. 2 ) described above, thereby giving the table  1  an overall uniform appearance. 
     With specific reference to  FIG. 4B , the beam connecting bracket assembly  52  is shown in an exploded view and is considered to be a complimentary mirror image of the beam connecting bracket assembly  50  described above. Thus, for description purposes, the beam connecting bracket assembly  52  will be described in detail below with the beam connecting bracket assembly  50  having corresponding component parts. The beam connecting bracket assembly  52  is shown having a connecting plate  62  separated into first and second sides  64 ,  66  by a vertical slot  68 . The first side  64  includes upper and lower connecting flanges  70 ,  72  having a wedged slot  74  disposed therebetween. The second side  66  includes upper and lower connecting flanges  76 ,  78  with a wedged slot  80  disposed therebetween. As shown in  FIG. 4B , the upper and lower connecting flanges  76 ,  78  of the second side  66  of the connecting plate  62  are longer than the upper and lower connecting flanges  70 ,  72  of the first side  64  of the connecting plate  62 . In assembly, the upper and lower connecting flanges  70 ,  72  are configured to be received in interior compartments of an associated beam, such as the beam  17  shown in  FIG. 2 . The upper and lower connecting flanges  76 ,  78  are configured to be received in interior compartments of an associated beam, such as the beam  19  shown in  FIG. 5 . In this way, the beam  17  is connected to the beam  19  by the connecting plate  62  in a serially aligned linear manner at the innermost ends  17   a ,  19   a  of the beams  17 ,  19 , respectively, as shown in  FIG. 2 . After the upper and lower connecting flanges  70 ,  72  of the first side  64  of the connecting plate  62  are received in interior compartments of a corresponding beam, a plurality of fasteners  82   a - 82   c  are mounted to mounting bosses disposed in the interior of the corresponding beam, as further described below with reference to  FIG. 5 . The connecting plate  62  is further coupled to other components of the beam connecting bracket assembly  52 , in assembly, as well as the trough support bracket  56 . Specifically, fastener  82   a  passes through a mounting aperture  84  disposed through the end plate  60  of the trough support bracket  56 . The fasteners  82   b ,  82   c  pass through mounting apertures  86 ,  88  disposed in a two-part bracket member  90  of the bracket assembly  52 . A bracket cover  92  covers the beam connecting bracket assembly  52  in assembly to provide a finished appearance for the center leg assembly  10 . The beam connecting bracket assembly  52  further includes lower plates  94 ,  96  having mounting apertures disposed there through for connecting the beam connecting bracket assembly  52  to the upper end  44   a  of the leg  44  using the fasteners  54 . 
     The connecting plate  62  ( FIGS. 4B and 4C ) is configured to mount to the trough support bracket  56  at the end plate  60  by the end plate  60  being received in the slot  68  of the connecting plate  62 . The connecting plate  62  is then secured thereto by welds at weld location X. The weld locations X are best shown in  FIG. 48  with reference to beam connecting bracket assembly  50 . With specific reference to  FIG. 4C , the trough support bracket  56  is shown coupled to the beam connecting bracket assemblies  50 ,  52 , and a two-part trough support bracket cover  98  is shown exploded away from the trough support bracket  56 . The configuration of the connection between the trough support bracket  56  and the beam connecting bracket assemblies  50 ,  52  is best shown in  FIG. 4D  with the trough support bracket  56  shown with end plates  58 ,  60  shown in phantom. 
     Referring now to  FIG. 5 , the longitudinally extending beams  16 - 19  ( FIG. 2 ) have a substantially identical, hollow construction, and are preferably extruded from aluminum or other like material. In  FIG. 5 , relative to  FIG. 2 , the beam  17  has been removed, and the center leg assembly  10  has also been removed to reveal a gap G where the center leg assembly  10  is located within the overall assembly ( FIG. 2 ). As shown in  FIG. 5 , with specific reference to the beam  19 , each longitudinal beam  16 - 19  includes interior and exterior sidewalls  100 ,  102 , an inclined top wall  104 , and a bottom wall  106  to define an interior space  108 . A pair of elongate grooves  110 ,  112  are formed along the intersections of the top wall  104  and the bottom wall  106  with the exterior sidewall  102 , and serve to detachably support the plurality of cantilevered top support brackets  15  ( FIG. 2 ) along the outer edges of the beams  16 - 19 . An interior groove  114  is provided along each of the interior faces of the beams  16 - 19  extending inwardly from the interior sidewall  100  and serves to detachably support wire management troughs  7  in the elongate window  5 . Further, a channel  115  and an adjacent connecting flange  115   a  are formed on the inclined top wall  104  near the interior sidewall  100  for connecting to worksurface connecting brackets and the like. 
     The interior space  108  ( FIG. 5 ) of the beam  19  includes upper and lower compartments  116 ,  118  located adjacent to the interior sidewall  100  and an open slot  119  disposed on an underside of the inclined top wall  104 . The upper and lower compartments  116 ,  118  are configured to receive the upper and lower connecting flanges  70 ,  72  or the upper and lower connecting flanges  76 ,  78  of the connecting plate  62  of a corresponding linear beam interconnecting bracket assembly  50 ,  52 , depending on the orientation of the table  1  ( FIG. 1 ). The interior  108  of the beam  19  further includes mounting bosses  120   a ,  120   b ,  120   c  which are accessible from the innermost end  19   a  of the beam  19 . As noted above, the beam  17  has been removed from  FIG. 5 , however, it is to be understood that the beam  17  also includes interior compartments similar to the upper and lower compartments  116 ,  118  and the mounting bosses  120   a - 120   c  shown with reference to the beam  19 . The mounting bosses  120   a - 120   c  are configured to align with the fasteners  82   a - 82   c  ( FIG. 4B ) for mounting a beam to an associated beam connecting bracket assembly, such as the beam connecting assemblies  50 ,  52 . The mounting bosses  120   a - 120   c  are shown accessible at the innermost end  19   a  of the beam  19 , but are also contemplated to be accessible at the outermost end  19   b  of the beam  19 . In this way, the mounting bosses  120   a - 120   c  can be used to mount an end leg assembly, such as the end leg assembly  6  shown in  FIG. 5 , to the beams  18 ,  19 . Thus, the center leg assembly  10  provides a connecting support member to connect the first and second sets of parallel beams  12 ,  14  in a linearly aligned manner by connecting the beam  16  to the beam  18 , and further connecting the beam  17  to the beam  19  at the innermost faces ( 16   a - 19   a ) thereof, as shown in  FIG. 2 . 
     As noted above, the legs  20 ,  22  and  42 ,  44  are similar in construction and the specific configuration of the legs will now be described with reference to  FIGS. 6A-6C . Referring now to  FIG. 6A , a leg assembly  150  is shown having a main body portion  152  with upper and lower ends  154 ,  156 . The upper end  154  includes a connecting surface  158  having a plurality of mounting apertures  160 ,  162  disposed thereon. The connecting surface  158  and mounting apertures  160 ,  162  are used to couple the leg assembly  150  to an associated mounting bracket of the table frame  2  ( FIG. 2 ). A base member  159  is coupled to the lower end  156  and is adjustable with respect to the body portion  152 , as further described below. A cover member  164  is shown coupled to the body portion  152  of the leg assembly  150 , wherein the cover member  164  is a removable cover member configured to close off a wireway or raceway  166  disposed centrally and extending longitudinally along the body portion  152  of the leg assembly  150 . The raceway  166 , best shown in  FIG. 6B , is essentially defined by a hollow interior of the body portion  152  and is used to route wires, cables, data and power connections through the leg assembly  150 . Upper and lower access apertures  170 ,  172  are defined between the end of the cover member  164  and the edges of the raceway  166 . The upper and lower access apertures  170 ,  172  provide near tabletop access and near floor level access to the raceway  166 , respectively, for wires and cables routed through the raceway  166 . As shown in  FIG. 6A , the lower access aperture  172  is generally defined by a relief portion disposed in the cover member  164  and a relief portion disposed on the body portion  152  of the leg assembly  150 . 
     Referring now to  FIG. 6B , the cover member  164  has been removed to fully reveal the raceway  166  which is generally defined by an inner surface  152 A of the body portion  152 . Disposed within the raceway  166 , a number of spaced-apart wire retainer assemblies  174 A- 174 C are mounted to the inner surface  152 A of the body portion  152  of the leg assembly  150 . In use, the wire retainer assemblies  174 A- 174 C are configured to retain wires and cables routed through the raceway  166 . With specific reference to  FIG. 6C , the wire retainer assembly  174 B is shown as a representative image of the wire retainer assemblies  174 A- 174 C shown in  FIG. 6B . The wire retainer assembly  174 B is mounted via a fastener, such as a screw  176 , to a mounting location or boss  178 B disposed on the inner surface  152 A of the body portion  152  of the leg assembly  150 . Each wire retainer assembly  174 A- 174 C includes a retainer bracket  180  pivotably coupled to an end of the boss  178 B by the screw  176 , such that the retainer bracket  180  is pivotable in direction  182  between an open position O ( FIG. 6C ) and a closed position C ( FIG. 6D ). A stop tab  181  is configured to abut an inner wall of the raceway  166  to prevent over-rotation of the retainer bracket  180  from the open position O to the closed position C. In the illustrated example, the retainer bracket  180  includes a mounting boss  184  disposed on a central portion thereof. In assembly, the mounting bosses  184  of the retainer brackets  180  align with mounting apertures  168 A- 168 C disposed on the cover member  164  for coupling the cover member  164  to the leg assembly  150  at the locations of the wire retainer assemblies  174 A- 174 C via fasteners  186 . Preferably, the wire retainer assemblies comprise a molded plastic, however, other suitable materials including wood may also be utilized. The configuration of the wire retainer assemblies allows an installer or user to secure wires within the raceway before installing the cover member and similarly to keep wires secured within the raceway after removing the cover members, improving the efficiency of installation and ease of wire management during use. The number of wire retainer assemblies may vary in some embodiments depending on the length of the leg, the types of wires likely to be secured within the raceway, and/or other constraints. 
     Referring to  FIG. 6E , the base member  159  of the leg assembly  150  is shown exploded away from the body portion  152 . An exploded adjustment mechanism  190  ( FIG. 7A ) is shown near the lower end  156  of the leg assembly  150 . In assembly, the adjustment mechanism  190  is positioned between and couples the base member  159  to the body portion  152  of the leg assembly  150 . In use, the adjustment mechanism  190  adjusts the base member  159  of the leg assembly  150  relative to the body portion  152  of the leg assembly  150 . The adjustment mechanism  190  allows for the overall leg assembly  150  to be adjusted for uneven surfaces, or other like conditions which may prevent a table frame from providing a level worksurface. In the illustrated example, the adjustment mechanism  190  includes a threaded shaft  191  and a pair of collar members, including a first collar member  192  and a second collar member  193 . Specifically, the lower end  156  of the body portion  152  (a portion of which is shown in  FIGS. 6E and 6F ) includes an end wall  194  having a centrally located threaded aperture  195  that threadably receives the threaded shaft  191  therein. Alternatively, the threaded shaft  191  may be fixedly received within the aperture  197  such that the shaft  191  does not rotate with respect to the body portion  152 . The base member  159  includes a centrally located boss  196  having a threaded aperture  197  that receives an opposite end of the threaded shaft  191  therein, such that rotating the base member  159  with respect to the body portion  150  either moves the base member  159  closer to or away from the body portion  150 , thereby shortening or extending an overall length of the leg assembly  150  as described below. 
     The first collar member  192  includes a circumferentially-extending lip  198  extending about a cylindrical wall  199  and a pair of mounting legs  200  extending opposite the lip  198  Each leg  200  includes a mounting aperture  201  that receives a mounting screw (not shown) therein, which is ultimately threadably received into one of a pair of corresponding mounting apertures  202  located within the end wall  194  of the lower end  156  of the body portion  152 , thereby securing the first collar member  192  to the lower end  156 . As best illustrated in  FIGS. 7A and 7B , the second collar member  193  includes a circumferentially-extending lip  202  ending about an end of a cylindrical wall  203  that is received into an interior  204  of the base member  159  and which telescopingly receives the cylindrical wall  199  of the first collar member  192  therein. 
     Further, either of the collar members  192 ,  193  may include a position indication line  220  positioned along the length thereof so as to provide a visual indication of the overall travel and position of the adjustment mechanism  190 , thereby preventing an operator from accidentally completely removing the base member  159  from threaded engagement with the shaft  191 . Similarly, the distal ends of either one or both of the collar members  192 ,  193  may be utilized in a similar manner by indicating to the operator that an extreme range of adjustment or travel of the adjustment mechanism  193  has been reached. It is also noted that the collar members  192 ,  193  can be provided in a variety of colors to either match or compliment colors selected for the remaining parts of the leg assembly  150  and/or worksurfaces  3 ,  4 . As further shown in  FIGS. 6E, 7A, 7B  a fastener  205  is received through an aperture  206  of the base member  159  and couples a foot member or plug  207  to the lower end of the base member  159 , such that the base member  159  and the foot member  207  cooperate to form a base member assembly  211 . The foot member  207  may be provided in a variety of configurations and in a variety of materials so as to provide a gripping support with an associated floor surface, a sliding support with the floor surface, a wear resistant surface, and the like. It is noted that the configuration of the foot member  207  and the base member  159  allow for easy replacement of the foot member  207  should the foot member  207  become worn, damaged or discolored. 
     With further reference to  FIG. 6A , the base member  159  is shown in a raised position R relative to the body portion  152  of the leg assembly  150 , thereby resulting in the shortest overall length of the leg assembly  150  and lowest elevation of a corresponding portion of a support worksurface. Referring now to  FIG. 8 , the base member  159  is shown in a lowered position L relative to the body portion  152  of the leg assembly  150 , thereby resulting in an increase to the overall length of the leg assembly  150  and a raising of a corresponding portion of a support worksurface. The adjustment mechanism  190  is used to move the base member  159  between the raised and lowered positions R, L by rotating the base member  159  in a direction as indicated by arrow  212 . In this way, the base member  159  can be quickly adjusted in a direction indicated by arrow  214  between the raised and lowered positions R, L, or any position therebetween, by a user without the need for outside adjusting tools in an office environment or other like setting. Further, the collar members  192 ,  193  telescope with respect to one another, thereby aesthetically filling the gap created between the end wall  194  of the body portion  150  and the base member  159 . A user may adjust various legs to positions at or between R, L to ensure a work surface is level or at a desired incline.
