Abstract
A table construction includes a base having a pair of legs secured together by a transverse beam, and a tabletop pivoted to a top of the legs for movement between a horizontal use position and a vertical storage position. A pair of support arms are pivoted to the top of the legs for selectively holding the tabletop in the horizontal use position. The support arms are spring-biased and pivoted at an angle so that they counterbalance a weight of the tabletop during its pivotal movement. Ganging connectors on opposite ends of the tabletop automatically interconnect adjacent tables upon pushing adjacent tables together. The legs each include first and second castings that bolt together and that are arranged to matably nest when tables are moved together for storage. A utility raceway structure attached to the base includes a frame that defines upper and lower chambers and further includes upper and lower lockable doors providing separate access to the upper and lower chambers, respectively. A utility outlet is releasably attached to the frame, and includes a face accessible in the first chamber and includes a utility supply connector accessible from below the upper transverse beam. A utility supply conduit is positioned in the second chamber and operably connected to the utility supply connector.
Description




BACKGROUND OF THE INVENTION




The present invention relates to work tables configured to support utilities, configured to gang together during use, and configured to permit dense storage.




Tables are commonly used in work, home, community, and educational environments to provide flat worksurfaces that can be flexibly used to support group activities. It is known to provide portable tables that can be arranged and rearranged for changing needs, and it is known to provide electrified tables that support electronic equipment, such as computers, communication equipment, and/or food heaters. However, improvements are desired to make tables even more adapted for flexible and ergonomic use and to facilitate their rearrangeability and reconfigurability, while maintaining a clean appearance. For example, it is important that utilities be supported and also that utilities be easily added, deleted, changed and/or accessed. At the same time, it is preferable to provide some level of security for the utility supply and/or the utility ports and connections. Further, the tables must preferably provide a clean and uncluttered look, even when a computer with multiple power and communication lines is connected. In addition to being useful, it is desirable to construct the tables to permit dense storage when not in use, and to construct the tables for ganging in secure but easily releasable arrangements.




Accordingly, a table is desired solving the aforementioned problems and offering the aforementioned advantages.




SUMMARY OF THE PRESENT INVENTION




In one aspect of the present invention, a table construction includes a base, a tabletop pivoted to the base for movement about a first axis between a horizontal use position and an angled storage position, and at least one support arm pivoted to the base. The support arm is movable about a second axis between a tabletop-braced position where the tabletop is held in the horizontal use position and a released position where the tabletop is released for movement to the storage position. The at least one arm is biased and pivoted to slidably engage the tabletop and counterbalance a weight of the tabletop as the tabletop is pivoted between the use and storage positions.




In another aspect of the present invention, a table construction includes a base, and a tabletop pivoted to the base for movement about a first axis between a horizontal use position and an angled storage position. The base includes a pair of legs connected by a transverse beam. The pair of legs each include first and second leg members having joint sections that matingly engage and are secured together. The first leg member has a forward extension and the second leg member has a rearward extension, with the forward extension being inboard of the rearward extension so that, when the tabletop is in the storage position, the forward extension of the table construction is adapted to extend inboard of and adjacent a rearward extension of a similar table construction when nested thereagainst.




In yet another aspect of the present invention, a table construction includes first and second tables each having a base and a tabletop supported on the associated base. The first table includes a male connector at a first end and the second table includes a female connector at a second end configured to releasably engage the male connector. The female connector defines a funnel-shaped chute with angled sidewalls shaped to receive the male connector and shaped to automatically align the first and second tables in a ganged arrangement when the first and second tables are moved together.




In another aspect of the present invention, a table construction includes first and second tables each having a base with legs and a tabletop supported on the associated base. The first table includes a male connector at a first end and the second table includes a female connector at a second end configured to releasably engage the male connector. The male connector defines a nose surface shaped to matably engage the female connector to automatically align the first and second tables in a predetermined ganged arrangement as the first and second tables are moved together. The male connector is pivotally movable about a horizontal axis between a horizontal engagement position where the male connector extends from an associated one of the legs and a lowered storage position where the male connector is positioned adjacent the associated one leg.




In another aspect of the present invention, a table construction includes a base and a tabletop supported on the base. The base includes a pair of legs connected by a transverse beam. A utility module is attached to the base. The utility module defines upper and lower chambers and includes upper and lower doors providing separate access to the upper and lower chambers, respectively.




In another aspect of the present invention, a table construction includes a base, a tabletop attached to the base, and a utility module attached to the base. The utility module includes a frame with upper and lower transverse beams defining a chamber therebetween. A utility outlet is attached to the upper beam, the utility outlet including a face accessible from above the upper transverse beam that is adapted for releasable connection to a utility-using device and including a utility supply connector accessible from below the upper transverse beam. A utility supply conduit is positioned in the chamber and operably connected to the utility supply connector.




In another aspect of the present invention, a table construction includes a base, a tabletop for movement about a first axis between a horizontal use position and an angled storage position, and a utility module supported by the base. The utility module has a utility outlet that is covered and difficult to access when the tabletop is in the horizontal use position, but that is uncovered and readily accessible when the tabletop is in the angled storage position.




In another aspect of the present invention, a table construction includes first and second tables each having a base and a tabletop pivotally supported on the base for movement between a horizontal use position and an angled storage position. The first and second tables include mating ganging connectors configured to releasably engage and hold the first and second tables together in a fixed interconnected arrangement. The first and second tables when in the fixed interconnected arrangement have abutting edges. At least one of the abutting edges has a resilient edge material that compresses to tension the gaining connectors and also to prevent light leaks between the abutting edges when the tabletops are both in the horizontal use position, but further that flexes to allow the tabletops to be individually pivoted from the horizontal use position without adversely damaging and abrading either one of the abutting edges.




In another aspect of the present invention, a portable table includes a base, a tabletop pivoted to the base for movement between a use position and an angled storage position, and a ganging connector on one of the base and the tabletop. The ganging connector is adapted to engage a mating ganging connector on another table to hold the portable table in a ganged arrangement. A utility module is attached to one of the base and the tabletop and is adapted to supply utilities to utility-using devices on the tabletop.




In another aspect of the present invention, a table construction includes a base having first and second legs that are spaced apart. The first and second legs each include a top section with a top pivot mount being located at a first side of the top section and a fixed support being located at a second side of the top section opposite the first side. A tabletop includes a middle portion and front and rear portions. The tabletop is pivoted to the top pivot mounts on the first and second legs at locations in the middle portion of the tabletop so that a weight of the front portion counterbalances a weight of the rear portion as the tabletop is pivoted. The fixed support is positioned to engage and support the tabletop when the tabletop is pivoted to a horizontal use position.




These and other aspects, advantages, and objects will be further understood and appreciated by those skilled in the art upon a close reading of the present specification, claims and appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT




A table construction


40


(

FIG. 1

) is adapted for utilities, for ganging, and for nested storage. The table construction


40


includes a base


41


having a pair of legs


42


and


43


secured together by a transverse beam


44


and by a tabletop


45


pivoted to a top of the legs


42


and


43


. The tabletop


45


is pivoted for movement about an axis


46


between a horizontal use position (

FIGS. 4 and 6

, solid lines) and a vertical storage position (

FIGS. 4 and 6

, dashed lines). A pair of support arms


47


and


48


(

FIGS. 2 and 4

) are pivoted to the top of the


42


and


43


legs for selectively holding the tabletop


45


in the horizontal use position. The support arms


47


and


48


are spring-biased by springs


49


(

FIG. 37

) pivoted for movement about an angled axis


50


(

FIGS. 10-11

) at an angle from a plumb vertical direction


50


′ so that they counterbalance a weight of the tabletop


45


during its pivotal movement.




The legs


42


and


43


(

FIGS. 4-6

) are substantially mirror images of each other and each include first and second castings


53


and


54


that are attached together by bolts


55


and


56


(FIG.


21


). The castings


53


and


54


include laterally extending feet that are arranged in inboard and outboard positions to mateably nest when tables


40


are moved together for storage (FIGS.


7


-


8


). The legs


42


and


43


are configured to nest into the legs of an adjacent similar table


40


, such that the table constructions


40


are storable in a dense nested arrangement that saves at least about 50% of occupied space.




The table


40


includes mating ganging connectors


51


and


52


(

FIGS. 24-25

) attached to legs


42


and


43


on opposite ends of the tabletop


45


. The ganging connectors


51


and


52


are configured to automatically align and interconnect adjacent tables


40


upon pushing the adjacent tables together (FIGS.


1


and


40


).




A utility module


60


(

FIGS. 41 and 42

) (sometimes also referred to herein as a “utility raceway structure”) is attached to the base


41


and includes a frame


61


that defines upper and lower chambers


62


and


63


and further includes front and rear lower doors


64


and front and rear upper doors


65


providing separate access to the upper and lower chambers


62


and


63


, respectively. Notably, it is contemplated that one or both of the doors can be locked to provide limited access to one or both of the chambers


62


and


63


. A utility outlet


66


is releasably attached to the frame


61


, and includes a face


67


accessible from above in the upper chamber


62


and includes a utility supply connector


68


(such as electrical terminals) accessible from only the lower chamber


63


. Utility supply conduit


69


is positioned in the lower chamber


63


and is operably connected to the utility supply connector


68


.




More specifically in regard to the legs, the legs


42


and


43


are substantially mirror images of each other. Accordingly, only leg


42


is described hereafter to reduce redundant discussion except where discussion of leg


43


is also required. A person of ordinary skill will understand the structure of the leg


43


from the discussion of leg


42


. Leg


42


is made of two castings bolted together (See FIGS.


20


-


21


), one being a larger casting


53


(

FIGS. 10-12

) and the other being a smaller casting


54


(See FIGS.


13


-


15


). Leg


43


is also made of two castings, with the smaller casting


54


being a mirror image of the casting


54


, but the larger casting


53


being the same as for leg


42


, as discussed below. The casting


53


(

FIGS. 10-12

) is L-shaped and includes an elongated vertically-extending section


70


and an elongated horizontally extending forward section


71


. The sections


70


and


71


have an I-beam-like cross-sectional shape, but it is noted that the center flange and the edge webs of the


1


-beam-like shape are generously radiused where they join together for aesthetics. Thus, a contoured recess


70


′ and


71


′ are formed along sides of the casting


53


. The end of the forward section


71


includes an aesthetically contoured bulbous end


72


and a “down” boss


73


for receiving an up stud on a castor


74


. Preferably, the castor


74


includes a foot-operated brake that can be easily set to hold the table


40


in a selected position.




A joint is formed at the juncture of sections


70


and


71


(FIG.


10


), and includes a raised ridge


75


forming a socket with two attachment depressions


76


and


77


therein. A second attachment section


78


is integrally formed on a bottom portion of the vertically extending section


70


at a location opposite the forwardly extending section


71


and slightly thereabove in a piggyback fashion. This location provides a good and stable support for the transverse beam


44


on the legs


42


and


43


. The attachment section


78


includes a rectangular perimeter rib


79


forming a depression shaped to mateably receive an end of rectangular tubular transverse beam


44


. A pair of holes


80


are formed in the attachment section


78


. A reinforcement plug bracket


81


(

FIG. 21

) configured to fit into an end of the transverse beam


44


includes a pair of matching threaded holes


82


(or nuts welded in alignment with the holes). The plug bracket


81


is telescoped into an end of the transverse beam


44


and welded, screwed or otherwise secured in place. A pair of bolts


83


are extended through a stiff plate washer


84


through holes


80


and threadably into the holes


82


to secure the plug bracket


81


and beam


44


to the leg


42


. Notably, the large casting


53


is relatively flat and lies in a single plane, which simplifies its casting and secondary machining and finishing.




The top section


85


of the larger casting


53


(

FIG. 10

) includes a horizontally extending flat top surface


85


′. A pivot hole


86


for pivotally supporting the tabletop


45


is formed in one end of the top section


85


and a stop


87


is formed on top of the other end. For example, the stop


87


might be a resilient rubber pad. The tabletop


45


is pivoted to the pivot hole


86


at a location slightly offset from a longitudinal centerline of the tabletop, such that the tabletop


45


tends to fall toward its vertical storage position by gravity. When in the horizontal use position, the tabletop


45


engages the stop


87


, which stabilizes the tabletop


45


in the use position in a first direction. The tabletop


45


is further held in the horizontal use position by the cantilevered support arms


47


and


48


, as discussed below.




Pivot mounts


88


(

FIGS. 10 and 11

) for support arms


47


(and


48


) are formed in the top section of the larger casting


53


on an inboard side. The pivot mounts


88


(

FIG. 11A

) each comprise a top and bottom flange


89


and


90


that combine with bearing caps


89


′ and


90


′ to form holes defining the axis of rotation


50


for the associated support arm


47


(or


48


). The support arm


47


(

FIG. 36

) includes a pivot pin


94


that extends into rotational engagement with the holes in flanges


89


and


90


to define the axis


50


. The axis


50


(

FIGS. 10 and 11

, and also

FIGS. 2 and 5

) extends at an angle of about 5 to 15 degrees from a plumbed vertical direction


50


′ (

FIG. 11

) when viewed from a front, and at an angle of about


5


to


15


degrees from a plumbed vertical direction


50


′ when viewed from a side (FIG.


10


). A coil spring


93


(

FIG. 36

) wraps around a lower part of the pivot pin


94


of the support arm


47


(and


48


). The spring


93


includes a first end that engages a pin stop


92


on the support arm


47


, and includes a second end that engages the large casting


53


. Preferably, the spring


93


biases the support arm


47


(and


48


) outwardly to about


45


degrees, which is significantly short of a fully extended position. A weight of the tabletop


45


will push the support arm


47


(and


48


) from this “45 degree” position to the retracted position. Thus, the tabletop will not be held in an unsecure position with the support arms


47


(and


48


) partially extended. The arrangement requires that an operator manually move the support arms


47


(and


48


) to the fully extended position where they extend 90 degrees as shown in

FIGS. 1-2

and


38


.




The support arm


47


(and


48


)(

FIG. 36

) is elongated, and includes a perpendicular latching pin


163


that engages the underside of the tabletop


45


. A latch


163


for releasably engaging the pin


163


(

FIG. 38A

) includes a plate


164


screwed to the underside of the tabletop


45


. The plate


164


includes slots


165


on each side that form a track, and a groove


165


′ (

FIG. 34

) is cut into the tabletop


45


under the slots


165


. A latch body


166


includes follower flanges


167


that slide along the slots


165


and hook under the plate


164


. A spring


168


(

FIG. 38A

) biases the latch body


166


toward a semi-secure latched position


170


. A front edge of the latch body


166


defines an angled surface


171


and a catch pocket


172


. The latch body


166


is movable between a released position


173


, the semi-secure latched position


170


, and a detent-secure latched position


174


. As the latch body


166


is moved to the secure latched position, the latch body


166


wedges under the tabletop


45


to prevent the tabletop


45


from pivoting or “teetering” at the pivot hole


86


. It is contemplated that friction will hold the latch body


166


. Alternatively, a detent finger


175


on latch body


166


is configured to resiliently engage a depression along the slots


165


, and engages the depression when in the detent-locked position


174


for increased security.




When the support arm


47


is moved toward the latch body


166


, the latching pin


163


engages the angled surface


171


and drives the latch body toward the released position


173


. When the support arm


47


moves to its fully extended position, the latching pin


163


is aligned with the catch pocket


172


, such that the spring


168


pushes the latch body


166


to the semi-secure latched position


173


. In turn, the latching pin


163


slides along catch pocket


172


to a location near a bottom of the catch pocket


172


. A user grasps a handle portion


177


of the latch body


166


to pull the latch body


166


to the more secure, detent-locked position


174


. Notably, the combination of the spring-biased movement of the support arms


47


and


48


caused by the angle of the axis


50


, the rotation of the tabletop


45


about horizontal axis


46


, and the weigh distribution of the tabletop


45


relative to the axis


46


, causes the support arms


47


and


48


to counterbalance and support a weight of the tabletop


45


as the tabletop


45


moves from its horizontal use position to its vertical storage position. Specifically, the support arms


47


and


48


move along an arc (see

FIG. 6

) and slidably engage an undersurface of the tabletop


45


as shown by the phantom lines


95


in

FIGS. 6

,


38


and


38


A. The sliding motion of the support arms


47


and


48


cause the support arms


47


and


48


to move with increased leverage for added stability as the tabletop


45


reaches a horizontal position and as the support arms


47


and


48


near a fully extended position for holding the tabletop


45


in its horizontal use position.




The smaller casting


54


(

FIGS. 13-14

) includes an elongated angled section


101


and an elongated down section


102


integrally formed on a bottom of the angled section


101


. The smaller casting


54


includes an upper end with a horizontally extending protrusion


103


shaped to mateably engage the raised ridge


75


forming the socket on the large casting


53


(FIG.


21


), and further includes two protrusions


104


and


105


that matingly engage the two attachment depressions


76


and


77


in the raised ridge


75


(FIG.


10


). A mounting plate washer


84


′ (

FIG. 21

) abuts a side of the large casting


53


opposite the ridge


75


. Bolts


55


and


56


extend through holes in the plate washer


84


′, through aligned holes in the large casting


53


, and threadably into the protrusions


104


and


105


in the smaller casting


54


to secure the castings


53


and


54


together.




An anti-scratch molded protector


108


(

FIGS. 16-19

and


21


) is attached to the underside of the smaller casting


54


(

FIG. 13

) with screws


109


. A second anti-scratch molded protector


110


(

FIG. 21

) is attached to a bottom surface of the large casting under the joindure of sections


70


and


71


. These two anti-scratch protectors


108


and


110


slidably engage mating portions of the castings


53


and


54


and protect the castings


53


and


54


from being scratched when two tables


40


are nested together. (See

FIG. 8.

)




As shown in

FIGS. 4

,


7


, and


8


, two tables


40


can be nested together by pivoting their respective tabletops


45


to a vertical storage position, and then by moving the tables


45


laterally together. The angled sections


101


of the small castings


54


combine to form a shape like a funnel (see

FIG. 7

) such that they direct the tables


40


together into an aligned and mating nested engagement. It is noted that the nesting feature allows the tables


40


to be stored in a reduced space that takes up about 50% or less storage area. This density of storage for the table


40


is unusual and is surprisingly and unexpectedly high for a table having the utility support and ganging capability of the present table. Specifically, the tables


40


can be nested together with each table


40


taking up only about an additional 12 inches. This is true, even though the tabletop


45


is about 30 inches to 36 inches wide, and the legs


42


(and


43


) span close to that same distance.




A first mount (

FIG. 22

) is formed on one of the large castings


53


for supporting the male ganging connector


51


, and a second mount is formed on the other of the large castings


53


for supporting the latch lever of the female ganging connector


52


, as discussed below. The first mount includes a pair of flanges


111


on an outboard side of the top of the large casting


53


. The flanges


111


each form a half circle bearing surface


112


. Bearing caps


113


are screw-attached to an inboard side of the large casting


53


. The bearing caps


113


include a half circle bearing surface that mates with the bearing surfaces


112


on the flanges


111


to form a pivot. The male connector


51


includes a body


114


with a pivot pin


115


extended through the body


114


, and a “lollipop” shaped hand


116


with a depression


116


′ therein. The pivot pin


115


pivotally engages the bearing surfaces


112


so that the pivot pin


115


is rotatably movable about a horizontal axis between a horizontal extended use position and a folded vertical storage position. A spring-biased ball


117


engages depressions


118


in the body


114


to hold the male ganging connector


51


in a selected position. In the storage position, the male ganging connector


51


is adjacent the vertical section


70


of the large casting


53


at a location where users will not accidentally bump into it.




The female ganging connector


52


(

FIGS. 23

,


28


-


29


,


31


) includes a bell-shaped or “chute” -defining ring member


120


that defines a funnel inlet


120


′. The ring member


120


attaches to an outboard side of the top of the large casting


53


. Notably, the flanges


111


are on an inboard side of the large casting


53


when the large casting


53


is used on the other leg


43


. The present table construction allows the same large casting


53


to be used on both legs


52


and


53


. The latching lever


121


(

FIG. 23

) includes a body having a pivot pin


122


transversely through its mid section, a hooked end


123


and a finger trigger portion


124


at its other end. With the pivot pin


122


engaged in the bearing surfaces


112


of the flanges


111


, the hooked end


123


extends to a central location in the funnel inlet


120


′ of the ring member


120


. A spring


125


engages an inboard side of the large casting


53


and engages a stud


126


on the lever


121


, such that the lever


121


is biased to a latched position. The finger trigger portion


124


includes a curved top surface that is C-shaped, and that it looks like a trigger such that it has a comfortable feel to a person operating the latching lever


121


. The trigger portion


124


is visible when the tabletop


45


is in its vertical storage position, and further is located near the ganging connectors


51


and


52


, such that it is easy to find and intuitive to operate, and so that it is readily accessible at all times.




As shown in

FIG. 31

, the latch lever


121


is movable between a normal at-rest position (where it engages a male ganging connector


51


) and a raised released position (shown in phantom lines) where a male ganging connector


51


, if present, is released. Notably, the male ganging connector


51


includes a tapered and rounded outer nose on its hand


116


. The nose is wedgeshaped and has a rounded nose surface configured to engage the hooked end


123


and automatically move the latching lever


121


to its released position when two tables


40


are moved together. Once fully together, the hooked end


123


snaps into secure engagement by action of the spring


125


to hold the two tables


40


together in a ganged arrangement. The hooked end


123


mateably engages and hooks into the depression


116


′ in the hand


116


such that the ganged connection closely and accurately defines the close spacing of the two tabletops


45


of the two ganged tables


40


. The funnel inlet


120


′ of the female ganging connector


52


and the rounded nose of the male ganging connector


51


both include angled side surfaces that abut to cause the two tables


40


to automatically align as the tables


40


are pushed together.




It is important when two tables


40


are ganged together that the tabletops


45


be tight together so that they can be moved as a unit or “train”. It is also preferable that there not be any light leak between the tabletops


45


. A tight fit helps assure an attractive ganged connection, and further helps prevent items from falling between tabletops


45


of two ganged tables


40


. Nonetheless, normal manufacturing variations can make it difficult to hold tight tolerances. A resilient edging


126


(

FIG. 39

) solves this problem by including a bulbous hollow portion


127


made of rubber, elastomer, or the like, and a “carrot” or barbed retention leg


128


made of stiffer or higher durometer material. The tabletop


45


includes an outer edge with a groove


129


cut therein. The retention leg


128


friction fits into the groove


129


to retain the edging


126


to the tabletop


45


. If necessary, corner pieces can be added of high durometer material to further assure that two tables, when ganged together, maintain alignment even when a user grasps an end of one table


45


as a way of manipulating a ganged arrangement of two or three tables


45


. Also, one or both of the front and rear edges of the tables


45


can be made of higher durometer material, if desired. The ganging connectors


51


and


52


engage such that the hollow portions


127


on each ganged tabletop


45


engage, causing the hollow portions


127


to compress slightly. Thus, the ganged connection of tables


40


does not have any light leak between tabletops


45


. The hollow portion


127


includes a flat top section that extends flush with a top surface of the tabletops


45


, and further includes a vertical side surface


130


. The vertical side surface


130


of ganged tables is slidable relative to the vertical side surface


130


of a mating ganged tabletop


45


. This permits the tabletops


45


of ganged interconnected tables


40


to be individually pivoted between use and storage positions, even while the tables


40


are interconnected. (See

FIG. 40.

) For example, this can facilitate connecting utilities of an electronic device on a given table to utilities in the adjacent table. Also, it facilitates working on ganged tables generally.




The frame


61


of utility module


60


(

FIGS. 41-42

) is shaped like a ladder, and includes a top extruded horizontal frame member


134


, a bottom horizontal frame member


135


, and several vertical frame members


136


. End frame members


133


are attached to each end of the frame


61


. The top frame member


134


(

FIG. 45

) includes a center web


137


, and front and rear lips


138


. Openings are formed in the center web


137


(

FIG. 41

) and U-shaped attachment brackets


139


are attached under the openings. It is contemplated that the openings can be cut in the center web


137


, or scored therein, such that they can be punched out in the field. The openings are sized and shaped to permit utility outlets, such as duplexes


140


, simplexes, and communication outlets


141


, to be snapped into the openings, with faces of the utility outlets being accessible from above the top frame member


134


(see FIG.


45


). Utility source cabling


69


is routed into the U-shaped attachment brackets


139


and is connected to utility source connectors, such as wire terminals, on a bottom of the utility outlets. Holders


143


on the vertical frame members


136


engage and hold the utility source cabling


142


. A resilient panel


144


(

FIG. 44

) attached to end frame members


133


have slits


145


and


146


and openings


147


and


148


that allow the utility source cabling


69


to be routed through the frame end members


133


and out of the utility module


60


for connection to a utility source (not specifically shown). Notably, the utility source cabling


69


can be permanently attached to the table


45


, and it is contemplated that they can have a length chosen to electrically connect to an electrical connector of an adjacent ganged table


45


. Specifically, with two tables


45


ganged together, the cabling


69


would be slipped through slot


145


(or


146


, see

FIG. 44

) and into apertures


147


(or


148


). The cabling


69


would then be connected to a left side of one of the electrical components


139


,


140


or


141


in the ganged table, to create a series electrical connection. It is contemplated that cabling


69


can also be extended into the utility module


60


from a front or rear of the table, or vertically up into the utility module


60


by incorporating openings in the front, rear or bottom of the utility module


60


.




A hinge bracket


150


(

FIG. 45

) is attached to the bottom horizontal frame member


135


and provides two flexible continuous hinge members


151


. Lower doors


64


each include a bottom edge


154


attached to the associated hinge member


151


, and include an upper edge lip


155


configured to releasably frictionally engage the lip


138


. A key lock


156


(

FIG. 42

) (or non-keyed twist lock) with a locking finger adapted to engage a flange on the frame


61


can be attached to the lower door


152


if added security is desired to prevent unauthorized access to the cavity defined between the horizontal frame members


134


and


135


where the utility source cabling


142


is located. The front and rear lower doors


64


are similar in construction and operation. A catch or hook-and-loop material can be used to hold the door


64


closed.




A second hinge


158


(

FIG. 45

) is attached to a top edge of each lower door


64


, and an upper door


65


is pivoted to the second hinge


158


. Each upper door


65


includes an upper flange


159


that extends inwardly and that frictionally engages either a top part of the large casting


53


or an inboard surface of the end frame members


133


. A key lock


160


(

FIG. 42

) can be provided on the upper door


64


if added security or added holding strength is needed. However, it is noted that, when the tabletop


45


is pivoted to its vertical storage position, a gap


161


(

FIG. 45

) is provided between the upper flanges


159


. such that the utility outlets are accessible and exposed for easy access. The frame


61


is attached to the base


41


(

FIG. 41

) by brackets


162


and end frame members


133


, each of which are screw-attached or otherwise secured together. A detent or hook-and-loop material can be used to hold the door closed.
