DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 2. Each of doors 12 and 13 are slidingly guided by a pair of spaced lower guide members 20 which extend into respective guideways 21 and 22 of lower track 23, track 23 being installed in doorway l5 by-spaced fasteners 24 along its length and being parallel to the upper track 17 which is similarly affixed in doorway 15 by spaced fasteners 25. A common type fascia plate 26 is connected by double-sided tape 27 or the like directly or adjacent to track 17 to outwardly cover or conceal the upper track 17 and the upwardly extending suspension members 28 and 28' which are suitably and rotatably connected at their upper end portions 29 and 30 to respective wheels 16, suspension members 28 and 28' hereinafter being more fully described.

Each of the doors 12 and 13 are substantially identical and further description of door 12 will sufiice to particularly describe the invention. Door 12 includes a panel frame as- 'sembly, generally indicated by reference numeral 30', and a panel 31 of any suitable material, such as plywood, paneling, plastic or the like. The frame assembly 30 includes a pair of generally horizontal and identical rails 32 and 33 and a pair of generally vertical and identical stiles 34 and 35, stile 34 being beneath stile 35 of door 13, and four unitary comer connectors, including corner connectors '37 and 38, disposed in each comer and connecting one stile and one rail together, as hereinafter more fully disclosed. Each of the rails 32 and 33 includes a channel 40 opening and facing inwardly with respect to the panel 31 and receiving respective horizontal edge portions 41 and 42 of panel 31 thereinto as depicted in FIG. 2. Each of the stiles 34 and 35 includes a channel 43 opening and facing inwardly with respect to the panel 31 and receiving respective vertical edge portion, including edge portion 44, of panel 31 thereinto as shown in FIG. 3.

Stiles 34 and 35 each includes another channel 46 opening and facing inwardly with respect to panel 31 and in the same general direction as channel 43, channel 46 having a rear side wall 47 extending horizontally and a lip 48 extending toward the other channel 43 and generally parallel with the channel bottom wall 49. A generally upright portion 50 of comer connector 37 is disposed in and conforms generally to the space defined by and internally of channel 46. Means are associated between upright portion and channel 46 to afiix the connector 37 thereto and is seen to herein specifically include a comer connector shoulder 51 engaging channel lip shoulder 52 which is formed by a cutout 53 in lip 48 as shown in FIG. 2, but substantially as more clearly shown in FIG. 7, hereinafter more fully described in connection with lower connector 38. With the shoulder 51 and 52 in engagement the upper surface 55 of laterally extending portion 56 of comer connector 37 is generally flush with the upper extent of rail 32 as shown in FIG. 2. Rail 32 includes an opening 58, as clearly seen in FIG. 4, spaced from the end portion 59 and through which another upright portion 60 extends, portion 60 being spaced from portion 50 and extends generally in the same direction as portion 50. Opening 58 is generally rectangular and the upper portion 62 of upright corner portion 60 is generally rectangular and substantially fits within opening 58. Means are associated between upright portion 60 and rail 32 to affix the connector 37 thereto and is seen to herein specifically include a comer connector shoulder 64 engaging beneath a shoulder 65 defining opening 58 in rail 32 whereby comer and rail are selflocked without other separate components.

Means are attached to corner connector 37 for adjusting the vertical extension and retraction of the suspension member 28 and is specifically shown as comprising an elongated screw 67 rotatably connected to upright portion 60, portion 60 including an elongated passageway 68 into which the lower portion 69 of elongated suspension member 28 extends. Lower portion 69 comprises a plurality of spaced, semicircular threaded portions 70, 71, and 72, as seen in FIG. 5, into which screw 67 is threaded. Housing upright portion 60 includes a pair of slits 74 and 75 therethrough which communicate with passageway 68 and vertical opening 76 also communicates with passageway 68. The screw 67 includes an enlarged head 77, a shank portion 78 journaled in opening 76, and an enlarged shoulder portion 79, shoulder portion 79 (with shank) and head portion 77 being larger in cross section than opening 76. The screw 67 is assembled in the housing upright portion 60 by passing the threaded portion 80 through opening 76 until the tapered conical portion 81 engages within opening 76; further forcing of the screw head 77 upwardly causes the resiliently expandable upright housing portion 60, particularly as provided by slits 74 and 75, to temporarily deform outwardly sufficiently to pass shoulder 79, whereupon shank portion 78 becomes seated within opening 76 and housing portion 60 returns to its non-deformed condition. Upon rotation in one direction of screw head 77, the suspension member 28 will be adjusted upwardly to broken line position 82 and will be retracted downwardly upon rotation of screw 67 in the opposite direction. To inhibit rotation of member 28, means are provided in the form of a pair of ribs 84 and 85 extending outwardly from the cylindrical lower portion 69, as seen from examination of FIGS. 3, 4 and 5, ribs 84 and 85 being stepped as shown in FIG. 4. Ribs 84 and 85 are disposed in respective guideways 86 and 87 to prevent any excessive rotation, there being some small play between the parts in a common manner.

While corner connector 37 is shown at the upper left hand comer of door 12, the identical corner connector may be employed at the upper right hand comer in which event shoulder 51' would engage a similar shoulder 52 of the corresponding lip of stile 35. In that event a similar suspension member 28 would also be used except such suspension member will be turned 180 so that the wheels 16 will be in alignment when disposed in guideway 19.

The lower corner connector 38 is identical to upper corner connector 37, comer connector 38 being shown in FIGS. 2, 6, 7 and 8. Guide member 20 is disposed within passageway 68 of corner connector 38 and is freely movable upwardly and downwardly therein. Elongated ribs 90 and 91 are positioned within guideways 86 and 87, as seen in FIG. 3, to prevent rotation of guide member 20 within housing upper portion 60, previously described as lower portion 60 of connector 37.

At the lower end portion 94 of guide member 20 is an integral tongue 95 terminating in a laterally extending foot 96 which prevents inadvertent removal of the guide member 20 from track 22, track 22 including a slot 97 along its length with the lateral distance thereof being less than the distance between the extremity of foot 96 and the rearward surfaces 98 of depending tongues 99 and 100, as clearly shown in FIG. 2 and 7, tongues 99 and 100 being spaced on either side of tongue 95 to provide proper and smooth operation of the guide member within track 22. Track 22 includes a shoulder 101 defining track slot 97 adapted to be engaged by foot 96 to prevent inadvertent dislodgement of tongues 95, 99 and 100 from within track 22. Middle tongue rearward surface 102 is spaced forwardly of surfaces 99 and 100 of respective tongues 98 and the forward surfaces 103 of tongues 99 and 100 are spaced rearwardly from forward surface 104 of middle tongue 95 such that the forward surface 104 and rearward surfaces 98 function to guide the member 20 in track 22 while foot 96 prevents disassembly of the member 20 from slidable connection with the track 22. Each of the tongues 95, 99 and 100 are provided with a cam surface 105 so that when the tongues are pressed into and through slot 97, the middle tongue 95 flexes laterally toward the pair of tongues 99 and 100, and the pair of tongues 99 and 100 may slightly flex toward middle tongue 95 to reduce the distance between the extent of foot 96 and rearward surfaces 98 so that the tongues may pass and be positioned within slot 97 with foot 96 extending laterally of shoulder 101 within track 22.

Attached to each of door panels 31 is a handle secured by fasteners 111 as shown in FIG. 9. A panel wedging clip 1 15 includes an indentation 116 which fits on a rib 117 formed in channel side wall 118 to prevent sliding removal downwardly, as shown in FIG. 10, after panel 31 has been forced into stile channel 43. On the opposite channel side wall 119 is formed a pair of ribs 120 which become slightly imbedded within panel 31, when the panel is wood paneling or the like, which further prevents removal of panel 31 after stile 34 is attached thereto.

Clip 115 includes a leg 124 positioned between panel 31 and side wall 118 and a laterally extending leg 125 which essentially serves as a handle to force leg 124 into position, if so desired, or the clip 115 may be positioned on side wall 118 before insertion of panel 31. The additional legs 126 and 127 appropriately space the clip 115 and secure the clip to wall 118 without independent components, glue or the like.
