DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The table frame 2 shown in Figure 1 has two dual leg support brackets 4 positioned at apposite ends of the center support beam 8. The dual leg support brackets 4 are preferably made of a cast metal and have a center recess for receiving the full depth of the center beam 8.
The center recess is open at one end a.nd closed at the opposite end. Removable corner legs 6 are mechanically attached to the dual leg support brackets 4. The dual leg support brackets 4 and the center beam 8 include a series of ports for mechanically fastening of a work surface to the table frame. Preferably, the work surface is attached either side of the beam 8 using ports 9 and at the corners of the diagonally extending support arms 104 using raised securing ports 110. The table frame 2 is reinforced or stiffened by the work surface.
In Figure 2, the table frame 2 of Figure 1 is shown with a right angle extension which is supported at the free end thereof by a cabinet 42 shown in dotted lines. The cabinet has on its upper surface a beam to cabinet connector 40. This connector includes a center recess for receiving the beam 8 which is mechanically fastened to the other center beam 8 by means of a right angle beam connector 20. This connector is mechanically fastened to the center beams 8 and if desired, the center beam 8 forming part of the extension to the right can also be mechanically fastened to each of the work surfaces.
The cabinet connector 40 includes two outwardly extending flanges for engaging and supporting a work surface. Preferably these flanges are at the same height as the center support beam and are mechanically connected to the work surface.
Figure 3 shows details of a preferred form of the center beam 8 which is manufactured as an extruded beam 8a. This beam includes a center cavity 60 running the length of the beam. The beam of Figure 3 is shown with the top surface down. As can be seen, the top section 62 includes outwardly extending securing flanges 64 either side of the beam section. Sidewalls 66 are generally perpendicular to the top section and these sidewalls are joined by the softly curved bottom surface 68. Each end of the beam 8a includes a series of end securing ports 70 provided in the sidewalls 66 and an aligned bottom securing port 72 and top securing port 74. The top section 62 includes a bolt slot 76 extending in the length of the beam. Preferably at the center of the beam, or at positions intermediate the length of the beam, the outwardly extending securing flanges 64 include securing ports 80. These are used for mechanically attaching the beam to the lower surface of the work surface. The work surface is preferably secured at least adjacent the mid point in the length of the beam and either side of the beam.
Each end of the extruded beam has a series of securing ports 70, 72 and 74 for completing the mechanical attachment to a leg support bracket. The extruded beam has excellent structural characteristics with respect to deflection. These structural characteristics are improved by attaching of the beam to the work surface to define a composite structure.
Additional details of the dual leg support bracket 4 are shown in Figure 5. This bracket is preferably a casting and has an extended center recess 90 for capturing and securing one end of the center beam 8a.
wH-11 aso-1cA
The bracket behind the recess 90 includes load transmitted area 103 which connects the diagonally extending support arms 104. As shown in Figure 1, area 103 includes a downwardly extending curved flange 107 to provide additional torsional rigidity of the leg support bracket.
One end of the center recess 90 is closed with the opposite end open for receiving the beam. The end of the beam 8a is fully received within the dual leg support bracket 40 such that the top of the beam is generally flush with the top of the outwardly and diagonally extending support arms 104. The center recess 90 has a curved bottom surface 92 corresponding to the bottom surface of beam 8a and has sidewalls 94 again which are positioned for snug engagement with the sidewalls 66 of the beam 8a. The securing flanges 64 are supported by the horizontal flanges 96 arid the outside of the securing flanges are in abutment with the upwardly extending stub flanges 98. Thus the center recess 90 is designed to be in contact with the exterior surfaces of the beam 8a. A
mechanical attachment of the beam 8a to the dual leg support bracket is accomplished using the securing ports 100 in the sidewalls 94 which align with one pair of the end securing ports 70. Typically a mechanical fastener is inserted through the combined structure for securement to the exterior of the dual leg support bracket or separate fasteners either side can be used.
The beam 8a is also connected using the bolt slot 76 and the securing port 77. The extended recess 90 provides good separation of the securing ports 100 and the securing port 102 in the dual leg support bracket 4.
These strong mechanical connections in combination with the high separation distance and the preferred structure of the bracket as a casting, provides a strong mechanical connection and excellent durability of the resulting table frame. Outwardly extending suppc>rt arms 104 include raised securing ports 110 which engage the lower surface of the table. These support arms also include securing ports 112 for mechanical connection to the legs 6.
Figure 5 shows a bolt connector 79 passing through the extruded beam 8a and through the securing port 102 in the dual leg support bracket 4. As can be seen, the head of the mechanical fastener is received within the bolt slot 76 and the top section 62 of the extruded beam 8a is flushed with the upper surface 105 of the dual leg support bracket 4.
Figure 6 shows a single leg corner bracket 140.
The bracket includes a first beam receiving recess 142 and a second beam receiving recess 144 positioned perpendicular to the first recess. The single support arm 146 extends diagonally away from the junction of these recesses. Each of the recesses 142 and 144 receive the end of the support beam 8a in a manner similar to that described in Figure 4 and 5. The inserted beams can be cut to form a miter joint or other joint at the junction of the two recesses. A series of ports 158 can engage the ends of the beams. The fir;~t recess 142 has securing ports 154 in the sidewalls of the recess adjacent the free edge of the bracket. A similar set of securing ports 142 are associated with the second recess 144. Each of the securing recesses 142 and 144 are extended in length to provide good separation between the securing ports 158 and the securing ports 154 or 152.
This separation distance will vary in accordance with the strength of the corner bracket 140 and the strength of the center supports beams 8a. It is preferred that this distance be at least 9 inches.
It can be seen in Figure 6 that the outwardly extending support arm 146 includes a raised boss area 150 for securing of the work surface to the leg. In _ g _ addition, the support arm includes a port 151 for securing of the leg 160 to the single leg corner bracket 140.
Figure 7 shows a die cast support bracket 170 for joining a first beam 172 intermediate its length to support beam 174 extending in a generally perpendicular manner to the longitudinal axis of the beam 172. This support bracket 170 includes the same center recess and sidewalls and support flanges for receiving a beam. As can be seen from the drawings, this bracket need not have the outwardly extending stub flanges. The support bracket 170 is mechanically fastened by means of fasteners 176 and 178 spaced either side of the bracket and secured to the beam 172. The perpendicularly extending support beam 174 is fastened by the same triangular layout of fasteners. In this case, the layout is defined by fastener 180 in engagement with the bottom surface of the beam 174 adjacent the end thereof and fasteners 182 on either side of the beam engaging the sidewalk .
An alternate beam connector is shown in Figure 8.
In this case, the right angle connector 190 is fabricated from sheet metal and has securing flanges 192 and 194 at one end of the bracket for engagement with the center support beam 196. The bracket 190 is provided with the center recess for receiving the beam 198. To provide additional stiffness, gusset flanges 200 and 202 are provided either side of the center recess of the bracket 190. These flanges are preferably welded to the flanges 194 and 192 and the sidewalls of the connector 190.
Figure 9 shows the manufacture of an alternate center support beam 210. The support beam is made of a composite structure comprising of the "U" shaped channel with outwardly extending flanges generally shown as 212 which is closed by a top member 214 which passes over top of the outwardly extending flanges and is bent over on the underside surface thereof. This composite structure is secured by a series of staple stitches 216 are provided along the length of the beam, preferably approximately every 12 inches. Each of the components of the composite beam 210 can be made from a suitable thickness of steel sheet. It is preferred that these components be made from 16 gauge steel sheet. This provides sufficient structural integrity for most applications. Obviously, the thickness of the material can be varied according to the particular application.
The mechanical securing ports can be appropriately reinforced for their intended function.
Figure 10 shows yet a further alternate structure where the composite structure is secured on the outwardly extending flanges by means of a roll formed gas seal edge 220.
Figure 11 is an exploded perspective view showing the attachment of extruded leg members &a to a dual leg support bracket 4. As can be seen, the extruded legs are of a triangular shape and a securing connector 7 is inserted into the leg by means of a press fit. This connector 7 includes a hole at the base thereof which receives the bolt fastener 9. The base of the extruded leg can be provided with a foot plug 11 having an adjustable leveller 13. The leg support brackets preferably include a downwardly extending projection for a press fit within an extruded leg. This serves to locate and support the leg. In addition, there is at least one downwardly extending flange which overlaps with the outside of the leg to provide additional strength.
If desired, this downwardly extending flange can be welded to the leg.
Figure 12 is a partial exploded perspective view showing the dual leg support brackets 4 receiving a center beam 8 and the various fastening components used 3 to secure the beam to the leg support brackets. As shown, three fasteners are used to secure the beam to each corner leg support bracket 4.
Figure 13 shows the assembled table frame 2 and a series of fasteners for securing of the work surface 5 to the table support frame 2.
Figure 14 is an exploded perspective view showing the attachment of the extruded leg 6a to the single leg corner bracket 140. The single support arm 146 includes a downwardly extending flange 147 for engaging one side of the extruded leg 6a.
Figure 15 Shows an example of a table frame comprising four single leg corner brackets 140 used with a series of connecting beams for supporting of the work surface 5.
Figure 16 shows a further variation where a table frame 2 has been formed by means of two dual leg support brackets 4 at one end of the table and a pair of single leg corner brackets 140 at the other end of the table connected by a beam 8. Two work surfaces 5a and 5b are attached to the table frame 2. A slight gap can be provided between these two work surfaces for receiving a small screen member which would extend upwardly between the two work surfaces 5a and 5b.
The modified dual leg support bracket 304 shown in Figure 17 has been reinforced on the bottom surface thereof to provide more effective transfer of forces from the beam to the legs. A Series of diagonally extending stiffening flanges 320 reinforce each of the outwardly extending support arms 310 by defining a series of alternating triangular cells 322 across the width of the arm. Each of the outwardly extending arms 310 joins with a central part of the dual leg support bracket where a beam will be secured within the recess 350 using the securement ports 346 and 348.
The dual leg support bracket has been reinforced by shallow ribs 347 forming an "X" type configuration on the lower surface of the central recess 350. The dual leg support bracket behind the central recess is reinforced by triangular reinforcing cells 330, 332 and 334. These are partially defined by the reinforcing webs 336 and 338. These cells essentially extend to the top surface of the bracket and are closed by the top surface.
This serves to stiffen the dual leg support bracket in a central region thereof which would otherwise tend to deflect due to the central recess 350.
The extruded leg 6 is mechanically attached at the edge of one of the support arms 310 by means of a bolt fastener 309 which passes through the stud 311 and into engagement with the press insert 307. The press insert 307 has three outwardly extending legs with the free edge of each leg having teeth 308 thereon. The press insert is force fitted into the longitudinally extending cavity of the leg 6 and the teeth 308 bite into the leg and lock the insert against withdrawal. A central, port is provided which engages the bolt fastener 309. The downwardly extending stud 311 is cast as part of the bracket and has a series of small ribs 321 on the sides of the stud. The leg 6 is forced onto the stud and the ribs provide a snug or interference fit with the leg. It can also be seen that the support arm 310 inwardly of the stud 311, has downwardly extending bracing flanges 317 and 319 which will engage one of the walls of the legs 6 and further improve the mechanical connection of the leg to the support bracket. The support bracket has a "U"
shaped slot 315 to simplify insertion of the leg on the stud 311. This "U" shaped slot also allows welding of the leg to the support bracket to further strengthen the connection if so desired.
The modified dual leg support bracket of Figure 17 effectively transfers the various forces exerted on the table to each of the legs and reduces any flexing of the support bracket due to the uneven pressure on the respective legs. These properties are further improved when the work surface is secured to the leg brace as previously described.
The dotted lines 323 show the approximate extent that the stud 311 is inserted into the leg 6.
The support bracket is further strengthened by the casting of the flanges 358 and 360 either side of the center recess 350 which merge with the support arms 310.
The support arms 310 have a generally smooth transition shown as 364 between the walls forming the central recess 2o and the support arms.
The table frame support system 400 of Figure 18 has a series of intermediate support brackets 402 secured to two central support beams 404. Intermediate support brackets 402 are typically required for extended lengths of the central beam 404 and assist in transferring loads applied to the work surface to the beam. Each support bracket is preferably secured to the work surface at four points and thus the strength of the work surface further reinforces the table frame system. Each of the support brackets has a downwardly extending flange 406 with a pair of securing ports 408. Bolts or other fasteners pass through the ports 408 and through similar ports in a support bracket to the opposite side of the beam. This serves to connect the two brackets together and to provide strong attachment of the brackets to the beam.
The support brackets 402 as shown in Figures 18 and 19 can be made from a stamping with the downwardly extending flange 406 joined in the center thereof by means of a weld 410. The support bracket 402 has a top surface 412 with securing ports 414 for engaging the work surface and triangular side flanges 416. These flanges 416 cooperate with the downwardly extending flange 406 to stiffen the bracket. The bracket is easily manufactured and significantly improves the structure of the system when the distance between support legs is high.
Figure 21 shows a "T" leg table frame system 500 which is often used for a stand alone table or desk. The table frame includes "T" legs 502 at opposite ends of the central support beam 506. Each of the "T" legs includes an upper bracket 508, mechanically connected to the leg extrusion 510 which in turn is mechanically connected to the leg support foot 512.
The upper bracket 508 and its connection to the leg extrusion 510 are partially shown in Figure 22. The leg extrusion 510 is mechanically secured to the upper bracket 508 by fastener 516 as well as fasteners 518 and 520 which engage the leg within the connecting ports 522 and 524 of the leg extrusion 510.
The upper leg support bracket 508 has two outwardly extending arms 530 and 532 having securing ports 534 and 536 for engaging the work surface. The bottom surfaces of the arms are visible in Figure 22 with each arm having a gentle curve thereacross. Each arm is recessed on the top surface as shown in Figure 23. This bracket also includes a downwardly extending stiffening flange 540. The bracket has a central recess 542 for receiving the central beam and includes the stiffening flanges 544 and 546 either side of the recess.
As shown in Figure 23, the arms 530 and 532 of the upper bracket 508 are aligned and effectively joined by the central webbed portion 550. The back wall 552 of the recess 542 cooperates with the triangular cells 554, 556 and 558 to stiffen the upper bracket 508 and provide high strength of the connection of the beam to the bracket.
This is further reinforced by the downwardly extending flange 540 which is below the recess and at one end thereof. Each of the arms 530 and 532 are recessed and reinforced by a series of diagonally extending web members 562. These cooperated with the sides of the arms to form triangular cells. The upper bracket 508 is preferably a cast unit.
The table frame 600 of Figure 24, is shown with an electrical raceway 602 provided at one edge of the table system. A flexible electrical conduit 604 provides power from the floor level to the bottom of the raceway. Tt should be noted that the raceway 602 in this case is basically an open trough for laying of electrical wires therein. Basically, this is part of a wire management system where excess electrical cords on the work surface can be stored in this electrical raceway. The raceway can also include various power outlet bars.
Figure 25 is a partial sectional view showing the relationship of the work surface 606, the raceway 602, the screen 608 and the mounting bracket 610. The mounting bracket is connected to the lower surface of the work surface 606 and provides support for the race 602 as well as the screen 608.
The bracket 610 as shown in Figure 26, has a work surface engaging arm 612, a vertical arm 614 for engaging the screen 608 and a lower arm 616 for supporting the raceway 602. The work surface engaging arm 612 has outwardly extending projections 618 with work surface securing ports 620 for positively securing the bracket to the work surface. The vertical arm 614 includes two ports for mechanically fastening with securing ports provided in the office screen 608. The lower arm 616 has securing ports 624 for cooperating with the bolt type fasteners 626. These are preferably stove bolt type heads which engage and are held against rotation slots in the raceway 602. The race 602 has a slot cut out 630 for allowing the vertical arm 614 to pass therethrough and generally be positioned within the perimeter of the raceway.
With the bracket shown in Figure 26, the screen can be positioned slightly beyond the edge of the work surface 606 forming a gap 632 at the edge of the work surface 606 as shown in Figure 25. This gap allows plugs and cords from equipment on the work surface 606 to be stored in the raceway 602. Electrical connection to a power bar or other connections preferably occurs in the raceway and thus, this type of equipment is also off the work surface. The bracket 610 is easily made as a single casting.
The bracket 610 can be used in a number of ways for supporting the raceway 602 and for supporting screens 608. Figure 27 shows one table frame arrangement where two work surfaces 640 and 542 are positioned back to back. A traverse central beam 644 is positioned below these work surfaces and forms an obstruction for securement of the screen. The screen 608 if of a depth to engage the bracket 610 cannot pass through the beam 644. To solve this particular problem, a screen support spacer 650 is positioned between the brackets 610 and is mechanically secured to each of the brackets by two fasteners 652 and 654.
The screen support spacer 650 includes an upwardly extending support rod 656 which is receivable within the support recess 658 disposed in the interior of the screen 608. A series of these screen support spacers are positioned along the length of the table between the brackets 610 to positively support the screen 608 between the work surfaces 640 and 642 and above any intermediary extending central beams such as beams 644.
Figure 29 shows a corner of a table with a snap-on cover member 660 secured to the exposed face of the raceway 602. Additional details are shown in Figure 30.
In this case, the bracket 610 is reversed such that the back of the raceway 602 is secured to the vertical arm 614 at a position spaced inwardly of the edge of the table. The cover 660 finishes the edge shown as 603 in Figure 30 and this cover is snapped over the edge 603.
The raceway 602 is mechanically secured to the bracket by means of fasteners 664. The raceway 602 has slot openings 668 for receiving these fasteners. The fasteners 664 can be partially released to allow the raceway 602 to be pulled outwardly to provide better access to the raceway at the exposed edge of the table.
As can be appreciated from a review of Figures 25 through 30, the brackets 610 can be used in a number of different ways for supporting of electrical raceways beneath a work surface and for supporting screens at any of a number of positions relative to the work surface.
For example, the screen 608 could be secured such that the upper edge of the screen is generally adjacent the top edge of the work surface and this would provide a modesty screen for the table. The screen can be secured at a mid position as generally shown in Figure 26 or can be secured in an upper position where the bottom edge of the screen is generally flush with the lower arm 616. In addition, the bracket can be used for supporting of a screen at a position essentially above the bracket by means of the spacer 650.
As with the table system, the bracket arrangement of Figures 25 through 30 allows a host of different arrangements to be carried out while using only a few parts and allowing variations of the connection of the components. This provides many advantages for the manufacturer, the installer and the end user as the parts are not dedicated to a single arrangement but can be used to achieve different arrangements. This is particularly valuable when the purchaser is considering the long term life of the product where the office layout can change several times to meeting changing needs in the work space.
With the present design, a small number of components are necessary for allowing a large variety of layouts to be possible.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The table frame 2 shown in Figure 1 has two dual leg support brackets 4 positioned at apposite ends of the center support beam 8. The dual leg support brackets 4 are preferably made of a cast metal and have a center recess for receiving the full depth of the center beam 8.
The center recess is open at one end a.nd closed at the opposite end. Removable corner legs 6 are mechanically attached to the dual leg support brackets 4. The dual leg support brackets 4 and the center beam 8 include a series of ports for mechanically fastening of a work surface to the table frame. Preferably, the work surface is attached either side of the beam 8 using ports 9 and at the corners of the diagonally extending support arms 104 using raised securing ports 110. The table frame 2 is reinforced or stiffened by the work surface.
In Figure 2, the table frame 2 of Figure 1 is shown with a right angle extension which is supported at the free end thereof by a cabinet 42 shown in dotted lines. The cabinet has on its upper surface a beam to cabinet connector 40. This connector includes a center recess for receiving the beam 8 which is mechanically fastened to the other center beam 8 by means of a right angle beam connector 20. This connector is mechanically fastened to the center beams 8 and if desired, the center beam 8 forming part of the extension to the right can also be mechanically fastened to each of the work surfaces.
The cabinet connector 40 includes two outwardly extending flanges for engaging and supporting a work surface. Preferably these flanges are at the same height as the center support beam and are mechanically connected to the work surface.
Figure 3 shows details of a preferred form of the center beam 8 which is manufactured as an extruded beam 8a. This beam includes a center cavity 60 running the length of the beam. The beam of Figure 3 is shown with the top surface down. As can be seen, the top section 62 includes outwardly extending securing flanges 64 either side of the beam section. Sidewalls 66 are generally perpendicular to the top section and these sidewalls are joined by the softly curved bottom surface 68. Each end of the beam 8a includes a series of end securing ports 70 provided in the sidewalls 66 and an aligned bottom securing port 72 and top securing port 74. The top section 62 includes a bolt slot 76 extending in the length of the beam. Preferably at the center of the beam, or at positions intermediate the length of the beam, the outwardly extending securing flanges 64 include securing ports 80. These are used for mechanically attaching the beam to the lower surface of the work surface. The work surface is preferably secured at least adjacent the mid point in the length of the beam and either side of the beam.
Each end of the extruded beam has a series of securing ports 70, 72 and 74 for completing the mechanical attachment to a leg support bracket. The extruded beam has excellent structural characteristics with respect to deflection. These structural characteristics are improved by attaching of the beam to the work surface to define a composite structure.
Additional details of the dual leg support bracket 4 are shown in Figure 5. This bracket is preferably a casting and has an extended center recess 90 for capturing and securing one end of the center beam 8a.
wH-11 aso-1cA
The bracket behind the recess 90 includes load transmitted area 103 which connects the diagonally extending support arms 104. As shown in Figure 1, area 103 includes a downwardly extending curved flange 107 to provide additional torsional rigidity of the leg support bracket.
One end of the center recess 90 is closed with the opposite end open for receiving the beam. The end of the beam 8a is fully received within the dual leg support bracket 40 such that the top of the beam is generally flush with the top of the outwardly and diagonally extending support arms 104. The center recess 90 has a curved bottom surface 92 corresponding to the bottom surface of beam 8a and has sidewalls 94 again which are positioned for snug engagement with the sidewalls 66 of the beam 8a. The securing flanges 64 are supported by the horizontal flanges 96 arid the outside of the securing flanges are in abutment with the upwardly extending stub flanges 98. Thus the center recess 90 is designed to be in contact with the exterior surfaces of the beam 8a. A
mechanical attachment of the beam 8a to the dual leg support bracket is accomplished using the securing ports 100 in the sidewalls 94 which align with one pair of the end securing ports 70. Typically a mechanical fastener is inserted through the combined structure for securement to the exterior of the dual leg support bracket or separate fasteners either side can be used.
The beam 8a is also connected using the bolt slot 76 and the securing port 77. The extended recess 90 provides good separation of the securing ports 100 and the securing port 102 in the dual leg support bracket 4.
These strong mechanical connections in combination with the high separation distance and the preferred structure of the bracket as a casting, provides a strong mechanical connection and excellent durability of the resulting table frame. Outwardly extending suppc>rt arms 104 include raised securing ports 110 which engage the lower surface of the table. These support arms also include securing ports 112 for mechanical connection to the legs 6.
Figure 5 shows a bolt connector 79 passing through the extruded beam 8a and through the securing port 102 in the dual leg support bracket 4. As can be seen, the head of the mechanical fastener is received within the bolt slot 76 and the top section 62 of the extruded beam 8a is flushed with the upper surface 105 of the dual leg support bracket 4.
Figure 6 shows a single leg corner bracket 140.
The bracket includes a first beam receiving recess 142 and a second beam receiving recess 144 positioned perpendicular to the first recess. The single support arm 146 extends diagonally away from the junction of these recesses. Each of the recesses 142 and 144 receive the end of the support beam 8a in a manner similar to that described in Figure 4 and 5. The inserted beams can be cut to form a miter joint or other joint at the junction of the two recesses. A series of ports 158 can engage the ends of the beams. The fir;~t recess 142 has securing ports 154 in the sidewalls of the recess adjacent the free edge of the bracket. A similar set of securing ports 142 are associated with the second recess 144. Each of the securing recesses 142 and 144 are extended in length to provide good separation between the securing ports 158 and the securing ports 154 or 152.
This separation distance will vary in accordance with the strength of the corner bracket 140 and the strength of the center supports beams 8a. It is preferred that this distance be at least 9 inches.
It can be seen in Figure 6 that the outwardly extending support arm 146 includes a raised boss area 150 for securing of the work surface to the leg. In _ g _ addition, the support arm includes a port 151 for securing of the leg 160 to the single leg corner bracket 140.
Figure 7 shows a die cast support bracket 170 for joining a first beam 172 intermediate its length to support beam 174 extending in a generally perpendicular manner to the longitudinal axis of the beam 172. This support bracket 170 includes the same center recess and sidewalls and support flanges for receiving a beam. As can be seen from the drawings, this bracket need not have the outwardly extending stub flanges. The support bracket 170 is mechanically fastened by means of fasteners 176 and 178 spaced either side of the bracket and secured to the beam 172. The perpendicularly extending support beam 174 is fastened by the same triangular layout of fasteners. In this case, the layout is defined by fastener 180 in engagement with the bottom surface of the beam 174 adjacent the end thereof and fasteners 182 on either side of the beam engaging the sidewalk .
An alternate beam connector is shown in Figure 8.
In this case, the right angle connector 190 is fabricated from sheet metal and has securing flanges 192 and 194 at one end of the bracket for engagement with the center support beam 196. The bracket 190 is provided with the center recess for receiving the beam 198. To provide additional stiffness, gusset flanges 200 and 202 are provided either side of the center recess of the bracket 190. These flanges are preferably welded to the flanges 194 and 192 and the sidewalls of the connector 190.
Figure 9 shows the manufacture of an alternate center support beam 210. The support beam is made of a composite structure comprising of the "U" shaped channel with outwardly extending flanges generally shown as 212 which is closed by a top member 214 which passes over top of the outwardly extending flanges and is bent over on the underside surface thereof. This composite structure is secured by a series of staple stitches 216 are provided along the length of the beam, preferably approximately every 12 inches. Each of the components of the composite beam 210 can be made from a suitable thickness of steel sheet. It is preferred that these components be made from 16 gauge steel sheet. This provides sufficient structural integrity for most applications. Obviously, the thickness of the material can be varied according to the particular application.
The mechanical securing ports can be appropriately reinforced for their intended function.
Figure 10 shows yet a further alternate structure where the composite structure is secured on the outwardly extending flanges by means of a roll formed gas seal edge 220.
Figure 11 is an exploded perspective view showing the attachment of extruded leg members &a to a dual leg support bracket 4. As can be seen, the extruded legs are of a triangular shape and a securing connector 7 is inserted into the leg by means of a press fit. This connector 7 includes a hole at the base thereof which receives the bolt fastener 9. The base of the extruded leg can be provided with a foot plug 11 having an adjustable leveller 13. The leg support brackets preferably include a downwardly extending projection for a press fit within an extruded leg. This serves to locate and support the leg. In addition, there is at least one downwardly extending flange which overlaps with the outside of the leg to provide additional strength.
If desired, this downwardly extending flange can be welded to the leg.
Figure 12 is a partial exploded perspective view showing the dual leg support brackets 4 receiving a center beam 8 and the various fastening components used 3 to secure the beam to the leg support brackets. As shown, three fasteners are used to secure the beam to each corner leg support bracket 4.
Figure 13 shows the assembled table frame 2 and a series of fasteners for securing of the work surface 5 to the table support frame 2.
Figure 14 is an exploded perspective view showing the attachment of the extruded leg 6a to the single leg corner bracket 140. The single support arm 146 includes a downwardly extending flange 147 for engaging one side of the extruded leg 6a.
Figure 15 Shows an example of a table frame comprising four single leg corner brackets 140 used with a series of connecting beams for supporting of the work surface 5.
Figure 16 shows a further variation where a table frame 2 has been formed by means of two dual leg support brackets 4 at one end of the table and a pair of single leg corner brackets 140 at the other end of the table connected by a beam 8. Two work surfaces 5a and 5b are attached to the table frame 2. A slight gap can be provided between these two work surfaces for receiving a small screen member which would extend upwardly between the two work surfaces 5a and 5b.
The modified dual leg support bracket 304 shown in Figure 17 has been reinforced on the bottom surface thereof to provide more effective transfer of forces from the beam to the legs. A Series of diagonally extending stiffening flanges 320 reinforce each of the outwardly extending support arms 310 by defining a series of alternating triangular cells 322 across the width of the arm. Each of the outwardly extending arms 310 joins with a central part of the dual leg support bracket where a beam will be secured within the recess 350 using the securement ports 346 and 348.
The dual leg support bracket has been reinforced by shallow ribs 347 forming an "X" type configuration on the lower surface of the central recess 350. The dual leg support bracket behind the central recess is reinforced by triangular reinforcing cells 330, 332 and 334. These are partially defined by the reinforcing webs 336 and 338. These cells essentially extend to the top surface of the bracket and are closed by the top surface.
This serves to stiffen the dual leg support bracket in a central region thereof which would otherwise tend to deflect due to the central recess 350.
The extruded leg 6 is mechanically attached at the edge of one of the support arms 310 by means of a bolt fastener 309 which passes through the stud 311 and into engagement with the press insert 307. The press insert 307 has three outwardly extending legs with the free edge of each leg having teeth 308 thereon. The press insert is force fitted into the longitudinally extending cavity of the leg 6 and the teeth 308 bite into the leg and lock the insert against withdrawal. A central, port is provided which engages the bolt fastener 309. The downwardly extending stud 311 is cast as part of the bracket and has a series of small ribs 321 on the sides of the stud. The leg 6 is forced onto the stud and the ribs provide a snug or interference fit with the leg. It can also be seen that the support arm 310 inwardly of the stud 311, has downwardly extending bracing flanges 317 and 319 which will engage one of the walls of the legs 6 and further improve the mechanical connection of the leg to the support bracket. The support bracket has a "U"
shaped slot 315 to simplify insertion of the leg on the stud 311. This "U" shaped slot also allows welding of the leg to the support bracket to further strengthen the connection if so desired.
The modified dual leg support bracket of Figure 17 effectively transfers the various forces exerted on the table to each of the legs and reduces any flexing of the support bracket due to the uneven pressure on the respective legs. These properties are further improved when the work surface is secured to the leg brace as previously described.
The dotted lines 323 show the approximate extent that the stud 311 is inserted into the leg 6.
The support bracket is further strengthened by the casting of the flanges 358 and 360 either side of the center recess 350 which merge with the support arms 310.
The support arms 310 have a generally smooth transition shown as 364 between the walls forming the central recess 2o and the support arms.
The table frame support system 400 of Figure 18 has a series of intermediate support brackets 402 secured to two central support beams 404. Intermediate support brackets 402 are typically required for extended lengths of the central beam 404 and assist in transferring loads applied to the work surface to the beam. Each support bracket is preferably secured to the work surface at four points and thus the strength of the work surface further reinforces the table frame system. Each of the support brackets has a downwardly extending flange 406 with a pair of securing ports 408. Bolts or other fasteners pass through the ports 408 and through similar ports in a support bracket to the opposite side of the beam. This serves to connect the two brackets together and to provide strong attachment of the brackets to the beam.
The support brackets 402 as shown in Figures 18 and 19 can be made from a stamping with the downwardly extending flange 406 joined in the center thereof by means of a weld 410. The support bracket 402 has a top surface 412 with securing ports 414 for engaging the work surface and triangular side flanges 416. These flanges 416 cooperate with the downwardly extending flange 406 to stiffen the bracket. The bracket is easily manufactured and significantly improves the structure of the system when the distance between support legs is high.
Figure 21 shows a "T" leg table frame system 500 which is often used for a stand alone table or desk. The table frame includes "T" legs 502 at opposite ends of the central support beam 506. Each of the "T" legs includes an upper bracket 508, mechanically connected to the leg extrusion 510 which in turn is mechanically connected to the leg support foot 512.
The upper bracket 508 and its connection to the leg extrusion 510 are partially shown in Figure 22. The leg extrusion 510 is mechanically secured to the upper bracket 508 by fastener 516 as well as fasteners 518 and 520 which engage the leg within the connecting ports 522 and 524 of the leg extrusion 510.
The upper leg support bracket 508 has two outwardly extending arms 530 and 532 having securing ports 534 and 536 for engaging the work surface. The bottom surfaces of the arms are visible in Figure 22 with each arm having a gentle curve thereacross. Each arm is recessed on the top surface as shown in Figure 23. This bracket also includes a downwardly extending stiffening flange 540. The bracket has a central recess 542 for receiving the central beam and includes the stiffening flanges 544 and 546 either side of the recess.
As shown in Figure 23, the arms 530 and 532 of the upper bracket 508 are aligned and effectively joined by the central webbed portion 550. The back wall 552 of the recess 542 cooperates with the triangular cells 554, 556 and 558 to stiffen the upper bracket 508 and provide high strength of the connection of the beam to the bracket.
This is further reinforced by the downwardly extending flange 540 which is below the recess and at one end thereof. Each of the arms 530 and 532 are recessed and reinforced by a series of diagonally extending web members 562. These cooperated with the sides of the arms to form triangular cells. The upper bracket 508 is preferably a cast unit.
The table frame 600 of Figure 24, is shown with an electrical raceway 602 provided at one edge of the table system. A flexible electrical conduit 604 provides power from the floor level to the bottom of the raceway. Tt should be noted that the raceway 602 in this case is basically an open trough for laying of electrical wires therein. Basically, this is part of a wire management system where excess electrical cords on the work surface can be stored in this electrical raceway. The raceway can also include various power outlet bars.
Figure 25 is a partial sectional view showing the relationship of the work surface 606, the raceway 602, the screen 608 and the mounting bracket 610. The mounting bracket is connected to the lower surface of the work surface 606 and provides support for the race 602 as well as the screen 608.
The bracket 610 as shown in Figure 26, has a work surface engaging arm 612, a vertical arm 614 for engaging the screen 608 and a lower arm 616 for supporting the raceway 602. The work surface engaging arm 612 has outwardly extending projections 618 with work surface securing ports 620 for positively securing the bracket to the work surface. The vertical arm 614 includes two ports for mechanically fastening with securing ports provided in the office screen 608. The lower arm 616 has securing ports 624 for cooperating with the bolt type fasteners 626. These are preferably stove bolt type heads which engage and are held against rotation slots in the raceway 602. The race 602 has a slot cut out 630 for allowing the vertical arm 614 to pass therethrough and generally be positioned within the perimeter of the raceway.
With the bracket shown in Figure 26, the screen can be positioned slightly beyond the edge of the work surface 606 forming a gap 632 at the edge of the work surface 606 as shown in Figure 25. This gap allows plugs and cords from equipment on the work surface 606 to be stored in the raceway 602. Electrical connection to a power bar or other connections preferably occurs in the raceway and thus, this type of equipment is also off the work surface. The bracket 610 is easily made as a single casting.
The bracket 610 can be used in a number of ways for supporting the raceway 602 and for supporting screens 608. Figure 27 shows one table frame arrangement where two work surfaces 640 and 542 are positioned back to back. A traverse central beam 644 is positioned below these work surfaces and forms an obstruction for securement of the screen. The screen 608 if of a depth to engage the bracket 610 cannot pass through the beam 644. To solve this particular problem, a screen support spacer 650 is positioned between the brackets 610 and is mechanically secured to each of the brackets by two fasteners 652 and 654.
The screen support spacer 650 includes an upwardly extending support rod 656 which is receivable within the support recess 658 disposed in the interior of the screen 608. A series of these screen support spacers are positioned along the length of the table between the brackets 610 to positively support the screen 608 between the work surfaces 640 and 642 and above any intermediary extending central beams such as beams 644.
Figure 29 shows a corner of a table with a snap-on cover member 660 secured to the exposed face of the raceway 602. Additional details are shown in Figure 30.
In this case, the bracket 610 is reversed such that the back of the raceway 602 is secured to the vertical arm 614 at a position spaced inwardly of the edge of the table. The cover 660 finishes the edge shown as 603 in Figure 30 and this cover is snapped over the edge 603.
The raceway 602 is mechanically secured to the bracket by means of fasteners 664. The raceway 602 has slot openings 668 for receiving these fasteners. The fasteners 664 can be partially released to allow the raceway 602 to be pulled outwardly to provide better access to the raceway at the exposed edge of the table.
As can be appreciated from a review of Figures 25 through 30, the brackets 610 can be used in a number of different ways for supporting of electrical raceways beneath a work surface and for supporting screens at any of a number of positions relative to the work surface.
For example, the screen 608 could be secured such that the upper edge of the screen is generally adjacent the top edge of the work surface and this would provide a modesty screen for the table. The screen can be secured at a mid position as generally shown in Figure 26 or can be secured in an upper position where the bottom edge of the screen is generally flush with the lower arm 616. In addition, the bracket can be used for supporting of a screen at a position essentially above the bracket by means of the spacer 650.
As with the table system, the bracket arrangement of Figures 25 through 30 allows a host of different arrangements to be carried out while using only a few parts and allowing variations of the connection of the components. This provides many advantages for the manufacturer, the installer and the end user as the parts are not dedicated to a single arrangement but can be used to achieve different arrangements. This is particularly valuable when the purchaser is considering the long term life of the product where the office layout can change several times to meeting changing needs in the work space.
With the present design, a small number of components are necessary for allowing a large variety of layouts to be possible.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
