SHEET 1 UF 2 II l2 3| {Ill IIIII INVENTOR JACK L. BEAVERS ATTORNEYS FREE-STANDING PANEL SYSTEM This invention relates to novel constructional apparatus suitable for partitioning room areas and supporting selected articles of furniture.

The present practice of partitioning rooms into separate areas is to use relatively permanent walls which are secured in place to the floors, walls and ceilings in such a way that any variation in room size and arrangement requires a major repair. This practice does not lend itself to a great deal of versatility and it usually requires considerable time together with skilled and trained personnel to make the needed changes and variations in the partitioning and rearranging of an office area. Another disadvantage of the present practices is there is little utilization of the partitioning walls to support the furniture in the room.

Accordingly, it is an object of this invention to provide a novel panel apparatus whereby interchangeable panels of selected sizes, construction and materials are supported in a desired structural configuration to meet the immediate room partitioning needs.

Yet another object of this invention is to provide a novel and improved panel assembly including interchangeable panels, panel connectors, and end posts capable of partitioning room areas and supporting selected articles of furniture such as desk tops, table tops, shelves, cabinets and the like in a convenient and efficient manner.

A further object of this invention is to provide a panel assembly which is vertically adjustable to make it level on existing support surfaces.

Still a further object of this invention is to provide a novel panel system whereby several standard panel sizes, shapes, colors, construction and materials may be readily interchanged and releasably but positively locked together in free-standing relation to accommodate changing room requirements without attachment to the floor, walls or ceiling of the room.

Yet a further object of this invention is to provide a novel panel system in which the elements are readily assembled and disassembled and has a substantial degree of rigidity and durability once assembled.

In accordance with the present invention there are provided flat panels of selected sizes, shapes and construction having grooves in their outer peripheral edges with adjacent edges of the panels being connected together by top and bottom junction plates. Each plate is elongated with slots at opposite ends which are releasably engageable with locking pins in the top and bottom grooves of the panels. A spline with angularly disposed legs releasably inserts into adjacent vertical grooves to cooperate with the junction plates in maintaining a predetermined alignment between the panels and has a column of vertically spaced slots which receive male connector projections on support brackets to support shelves, table tops, desk tops, drawers and like articles of furniture. An upright end post assembly provides added support for the free ends of connected panels. Level adjustors on the bottom junction plates and on the support bracket provide for a fully level assembly.

Other objects, advantages and capabilities of the present invention will become more apparent as the description proceeds taken in conjunction with the accompanying drawings, in which:

FIG. 2 is an exploded perspective view of a right angle corner assembly;

FIG. 3 is a sectional view taken along lines 33 of FIG. 2;

FIG. 4 is a sectional view through the cornerjunction with the spline in place in the vertical grooves;

FIG. 5 is a cross-sectional view of several shapes of junction plates;

FIG. 6 is a perspective view of an end support post for a panel assembly;

FIG. 7 is an enlarged fragmentary perspective view showing the coupling between the top plate and the upright standard of FIG. 6; I

FIG. 8 is a fragmentary side elevation view of an alternative form of support bracket;

FIG. 9 is a sectional view taken along lines 99 of FIG. 8; and

FIG. 10 is a sectional view taken along lines 10l0 of FIG. 8.

Referring now to the drawings, in FIG. 1 there is shown a self-supporting room partitioning assembly generally designated by numeral 11 which comprises individual panels 12 disposed upright and connected in a closely spaced, edge-to-edge relationship in a manner to be described so as to make up a desired wall configuration without requiring support from adjacent permanent walls or ceilings. This panel assembly supports a desk top 16, drawers 17 below the desk top, a cabinet 18 above the desk top, together with a filing bin 19 on a panel adjacent the desk top. It is understood that the assembled unit shown in FIG. 1 is an example of only one possible configuration and that the present invention affords a wide variety of partitioning configurations, a number of sizes and many furniture variations to meet the particular needs of a room area. The panels 12 are furnished in several standard sizes and may be of numerous materials such as natural woods and plastic laminates to give esthetic variety, and the office fumiture may include desks, filing bins, drawers, shelves, valances, sliding doors and the like.

With reference now to FIGS. 2 and 4, a corner assembly of panels 12' and 12" is shown in more detail. Panels 12' and 12" each have generally flat outer edges and each panel has grooves 23 in the vertical edges, a groove 24 in the top edge, and a groove 25 in the bottom edge. Each of these grooves is centered in the panel and the top and bottom grooves are preferably slightly wider and deeper than the vertical grooves. Each of panels 12' and 12" shown in FIG. 2 comprises an inner core 12a made preferably of flakeboard, an end facing plate 12b and an outer finished sheet or layer which may be carpeting represented at on panel 12' or a plastic or wood layer 12d as represented on panel 12" to provide the desired effect on the outer surface of the panel. A corner trim member 12e is provided at each corner along the vertical edge for the carpet layer 12c, while the wood or plastic laminate layers 12d either may extend the full length of the panel and overlap the facing plate 1212 or may be provided with a corner trim 122 as shown in FIGS. 2 and 4.

A top junction plate 31 and a bottom junction plate 32 releasably insert into the top and bottom edge grooves 24 and 25, respectively. The top junction plate 31 has a pair of elongated flat arms 31a and 31b disposed at right angles to one another which extend a substantial distance inwardly of the vertical edge of the panel to give substantial support for the assembly. Each top junction plate arm has a slot 33 opening in its bottom edge and adjacent its free end which slides over a vertically disposed male locking element 34 in the form of a cylindrical dowel pin centered in the groove in the top of the panel. This locking element 34 is wider than the top groove 24 to extend into its sides and penetrates to a substantial depth into the panel and is firmly held in the panel and this slot and pin locking arrangement facilitates the positioning of the top junction plate in the proper place on the panel and also serves to positively lock the panels together in a closely spaced edgeto-edge relation to one another. Similarly, the bottom junction plate 32 has elongated

flat arms

32a and 32b,

each having a locking slot 36 opening through the top edge adjacent its free end which fits into a locking dowel pin (not shown) centered in the bottom groove. Further, each bottom junction plate arm has an adjustable leveler 41 comprising an internally threaded sleeve 42 secured to the sides of the plate arm 32 as, for example, by welding along the upper edges, a threaded stem 43 threaded into the sleeve with a flat foot 44 forming a surface-engaging base. The stem 43 threads up and down in internal threads in the sleeve to adjust the effective length of the leveler. The foot 44 may be made of rubber, nylon or the like. This leveling adjustment structure serves to level the corners of an assembly and compensate for any irregularities in the surface on which the panels are supported.

A spline 46 having a right-angle cross section with

flat legs

46a and 46b disposed at right angles to one another is releasably inserted into the adjacent vertical grooves 23 in the panels. Spline 46 extends substantially the lengthwise extend of the vertical edges of the panels and terminates at the inner extremity of the top and bottom grooves 24 and 25. The vertical grooves and spline connector legs are sized so that the spline connector will readily slip into the groove and the depth of the vertical groove is selected in relation to the length of the spline legs so as to dispose the vertical edges of the panels in a closely spaced edge-to-edge relation, as best seen in FIG. 4. A plurality of vertical spaced slots 47 are provided in each of the legs of the spline between the corner formed by the legs and the terminal edges of the legs and these slots are in communication with the space between the connected panels so they will slidably receive the male connector ends of support brackets described hereinafter.

The top and bottom junction plates for a selected panel assembly joint have the same angular shape and a system of assembled panels will include junction plates having several cross-sectional shapes, as is illustrated in FIG. 1. Typical cross-sectional shapes for the junction plates, in addition to the right-angle shape shown in FIG. 4, are illustrated in more detail in FIG. and may include a straight shape 50 for connection with the end of a panel, a straight shape 51 for connection between panels, an acute inner angle shape 52, together with multiple leg configurations including a T-shape 53, Y-

shape 54, X-shape 55. Typical angles for the acute' angle of 105, 120, l35or 165. The spline shapes will have angles corresponding to those of the junction plates for the same junction and for each angular shape the spline slots 47 are disposed centrally in each leg for the right-angle shape.

For the support of articles of furniture from the upstanding panels 12 there is provided one or more support brackets 61 shown in FIG. 2. The support bracket has a right angle cross section with a top horizontal support leg 61a and a vertical leg 61b. The vertical leg 61b is generally L-shaped and supports inwardly extending, vertically spaced, slotted male connector projections 65 sized and spaced to insert into the slots 47. Connector projections 65 are flat-sided and have a reduced end portion 66 provided with an undercut slot 67 so that the reduced end portions will insert through the slot 47 and hook against the sides of the spline legs to provide a cantilever-type support surface area along the top leg 610. It is apparent that support brackets 61 may be positioned at various elevations adjacent the connected panels between the vertical edges of the panels to provide one or more laterally spaced, removable supports along the wall assembly for supporting a desired article of furniture.

For the support of a free end of the connected panels there is provided an end post assembly 71 including a base formed of a laterally extending flat base plate 72 together with a bottom end junction plate 50a disposed at right angles to the base plate to form a T-shaped base configuration. A vertical standard 75 extends upwardly from the center of the base plate to cover the free vertical edge of the connected panels, as best seen in FIG. 1. The bottom end plate 50a has a leveler device 41 for leveling adjustment at the end of the standing panel. A straight slotted end plate connector 50b is mounted on a tubular cap 76 having a pair of

dependent prongs

77 and 78. These prongs are sized and spaced to releasably insert into an upper open end of standard 75 so that the top end plate connector may be releasably inserted into place once the bottom junction plate 50a is in position.

An alternative form of support bracket shown in FIGS. 8, 9 and 10 provides for the level adjustment of the supported article of furniture. This adjustable support bracket 80 has an independent, movable support member 81 of right-angle cross section with a top leg 81a and a vertical leg 81b. This movable support member is vertically adjustably mounted on an L-- shaped stationary flange 82 which carries the vertically spaced slotted male connector projections 83 along its inner edge to insert into the spline slots 47 and further has a straight connector projection 84 at its lower end for added support. The adjustment for the support member 81 is provided by means ofa pivot member 85 between leg 81b and support 82 at the inner end of the support member together with a pair of spaced elongated slots 86 in the vertical leg 81);, one at a position intermediate its ends and the other adjacent its outer end together with a threaded bolt 87 welded to the flange and extending through the slot 86 so as to permit the support member to pivot up and down relative to the stationary support 82 and be held at a selected angle by a nut 88 threaded on the bolt.

Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example and that changes in details of structure may be made without departing from the spirit thereof.
