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.
It will be readily apparent to those skilled in the art that modifications and changes can be made from the disclosed preferred embodiment without departing from a scope of the present invention. Such modifications and variations are to be considered as included in the present invention, unless the claims by their language expressly require otherwise.
