referring now to fig1 the cabinet stand assembly which is the subject of the present invention is shown comprised of four panels 12 interengaged to form an assembly base 10 . a top closure member 14 is shown in outline form . in addition , a drop - in shelf 15 which is optional is shown within the assembly base . a plurality of holes 16 are provided along the vertical edges of each panel to support conventional hanger clips for drop - in shelving . the four panels are interengaged in overlapping configuration at each corner wherein the engaging edge portion of a panel is placed against the inside surface of an adjacent panel with the opposing edge portion forming part of the exterior surface of the assembly base 10 . the four lap joints 18 are identical in the assembly base structure . in fig2 the assembly base 10 is shown in exploded form with the placement of the releasable catches on each panel being identical . in particular , panel 12 has two releasable fasteners 20 affixed to one engaging edge and positioned equidistance from the panels horizontal center line . another pair of releasable fasteners is affixed to the large area interior surface of panel 20 &# 39 ; proximate to the opposing edge also equidistant from the horizontal center line . the placement of the releasable fasteners enables the panel configuration for the cabinet assembly base 10 to be formed using the corner lap joints as shown in fig1 . as a result , each panel 12 is made with the same height and width dimensions and is therefore interchangeable with other panels . during the assembly of the base 10 , the workman need not classify the different panels prior to assembly . installation of the fasteners of one panel into the receiving fasteners of an adjacent panel is the same for each of the four panels 12 . consequently , it is unlikely that any errors will occur during assembly and the possibility of having to disassemble a partially completed assembly is remote . the interior surface of the panel 12 is shown in fig4 wherein a pair of releasable fasteners 20 are affixed to the left hand engaging edge of the interior surface . as shown , optional holes 16 for receiving hanger clips to support drop - in shelving are placed in parallel alignment near the opposing edge portions of the panel . the use of shelves is optional and requires the use of a panel 24 having a central opening 25 therein as shown in fig3 . a door can be mounted in the panel by use of recessed hinges which are shown in outline form . the assembly of the present invention is further simplified for the workforce since the square cross sectional area accommodates a top closure member as shown in fig5 and 6 . the closure member 14 is provided with alignment guides 22 on its underside and the closure member may be placed on the base 10 without regard to orientation since the cross sectional area of the base is square . a typical square drop - in shelf 15 is shown in fig7 . the panels used to form the cabinet assembly are preferably constructed as shown in the cross sectional view of fig8 . the central portion of panel 12 is formed of an expanded foamed plastic core 30 which is bounded on either side by rigid plastic layer 32 . the panels are framed with wood around the perimeter of the foamed plastic core . the wood from provides a solid substrate for the attachment of the fasteners . a plastic protective layer 32 is preferably adhered to the outer surface of the members of the panel and is also used to cover the exposed edges of the panel as shown . by utilizing the foam core , the panels and the assembled cabinet base are relatively light as compared to the weight of conventional solid plywood or hardboard panels used in knock - down display furnishings . an embedded releasable fastener is shown in fig9 affixed to a slot formed in the edge portion of panel 12 . the fastener 20 is held in position in the slot by screws 21 which extend into the panel frame . the fastener includes a central portion which extends outwardly from the slot and has spaced raised portions thereon . a similar slot 23 is formed in the adjacent panel and includes a like fastener . these commercial fasteners releasably engage one another by inserting the central portions in the slots while the panels are slightly vertically misaligned . when moved into alignment , the raised portions are located adjacent to each other and firm engagement takes place . while the recessed mechanical fasteners are shown in fig9 the use of a combination of tapered pegs and holes can be utilized as well . for example , in fig1 , panel 12 contains a dowel 41 and the adjacent panel includes a receiving hole 40 . when inserted , frictional engagement between peg and hole secures the adjacent panels in alignment one to the other . it is to be noted that a variety of commercial fasteners can be utilized as long as they do not prevent the overlapping panels from resting adjacent to each other when assembled . an assembled cabinet base is provided with a top closure member , normally square in form which can be utilized with like assemblies to form a display array as shown in fig1 wherein the top closure members 42 and 43 abut each other . each of the top closure members can be provided with hook and loop type fasteners such as 3m dualock on its vertical edges so that the interengagement of adjacent top members ensures that alignment can be maintained during use . a corner top member 45 with a curved outer edge is shown supported by a pedestal 40 . the corner member enables a safe display area to be provided without having any sharp angles at the exposed corner of the work surface . as shown , the change in direction enables additional assemblies to be attached by moving top member 44 into engagement with the exposed vertical edge of the corner member . the use of the foam core and frame in combination with the rigid plastic exterior layers provides light weight cabinet base assemblies characterized by four lap joints at the corners which can be moved readily into position to form a variety of display structures . the disassembly or take - down of display furnishings utilizing one or more of the novel cabinet base assemblies is relatively simple and can be handled by one workman . the disassembled parts need not be classified as to different sized panels since all are of the same dimensions in the preferred embodiment shown in the drawings . the shape of the embodiment shown is square in cross - sectional area and other shapes using the lap joint construction can be formed by utilizing pairs of opposing panels having different widths . while the above description has referred to preferred embodiments of the invention , it is to be noted that many modifications and variations may be made therein without departing from the scope of the invention as claimed .
a modular furniture assembly of the knock - down type wherein four identical side panels are interengaged at corner lap joints to facilitate set tip and take - down . each panel has fasteners located on one edge and on the interior surface panel proximate to the opposing edge . the resultant structure is square in cross section . a square closure member forms the top surface .
