  • 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.
  • 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.
  • 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.
  • a table construction in one aspect of the present invention, 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.
  • a table construction in another aspect of the present invention, 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.
  • a table construction in yet another aspect of the present invention, 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.
  • a table construction in another aspect of the present invention, 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 predeteraiined 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.
  • a table construction in another aspect of the present invention, 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.
  • a table construction in another aspect of the present invention, 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 uti ity supply connector.
  • a table construction in another aspect of the present invention, 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.
  • 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.
  • a portable table in another aspect of the present invention, 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 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.

  • 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 38A. The sliding motion of the support arms 47 and 48 cause the support arms 47 and

  • 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.
  • 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.
  • 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.

  • the female ganging connector 52 (Figs. 23, 28-29, 31) includes a bell-shaped or
  • 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.
  • 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.
  • 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.
  • the male ganging connector 51 includes a tapered and rounded outer nose on its hand 116.
  • the nose is wedge-shaped 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.
  • 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.
  • 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.
  • 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.
  • 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 (Fig. 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.
  • 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).
  • 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).
  • 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
  • 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.
  • 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 132 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.

Abstract

Cette invention concerne une table (Fig. 1) comprenant un socle (41) constitué d'une paire de pieds (42, 43) reliés l'un à l'autre par une traverse (44), et un plateau (45) monté pivotant au haut des pieds (42, 43) et pouvant se déplacer entre une position horizontale de travail et une position verticale de rangement. Une paire de bras (47, 48), montés pivotant au sommet des pieds (42, 43), assurent le maintien du plateau de table (45) en position horizontale de travail. Ces bras (47, 48), qui sont sous charge de ressort, ont un angle de pivotement qui permet de contrebalancer l'effet d'un poids s'exerçant sur le plateau (45) pendant le pivotement. Des attaches (51, 53) situées sur les extrémités opposés du plateau (45) permettent de relier automatiquement des tables adjacentes lorsqu'on les pousse les unes contre les autres. Les pieds (42, 43) comportent chacun des premières et secondes pièces moulées qui se vissent les unes aux autres et qui sont prévues pour s'emboîter les unes dans les autre lorsque les tables sont réunies en vue de leur rangement.
