Abstract

A lightweight pull slide door construction for shelving which is either transparent or opaque and is notched at its upper corners to slide on a horizontally inwardly offset rod hanger that extends front to back within the opening defined by the front posts of the shelving. A front opening hook at each corner slidably engages the offset portions of the hanger in guided relationship and the hook portion pivotally engages the offsetting portion of the hanger at the front of the shelving, whereby a top portion of the door pivots forwardly behind the depending portion of the depending flange of the upper shelf, the notch accommodates the shelf corner securement, and the hooks determine the ''''hang'''' and levelness of the door when closed. The doors can be released and removed when in the open position through the space above the hanger and within the depending flanges of the upper shelf. In one embodiment a second hook member is provided extending inside of and under the hanger ahead of the tip end of the front opening hook and spaced therefrom on its inner side sufficiently to clear the offsetting portion of the hanger so that the sliding door, which rests at its side edges upon the hanger will be prevented from pivoting upon the offsetting portion of the hanger against the bottom of an adjacent upper shelf and will provide a thrust point to stabilize the door in its intermediate positions to serve as a temporary horizontal shelf extension.

sum 1 or 2 N VE N TORS IRWIN J. FERDINAND /RW/N R. KULB RSH Attorneys PATENTEUunv 16 197i SHEET 2 UF 2 A Horn eys DOOR CLOSURE FOR SHELVING BACKGROUND OF THE INVENTION It is known to provide modular knockdown steel shelving fabricated of lightweight rolled sheet metal comer supports and shelves which fasten together by various forms of comer clips. Metal shelving of this type is furnished with or without side panels and back panels and, in some embodiments, channels are provided above and below the opening defined by the front posts to receive a pair of overlapping sliding'doors which can assume positions on either side of the opening to form a closure. Shelving of this type must be easily fabricated, readily assembled and both laterally and vertically rigid so as to support considerable weight.

The provision of enclosing side and back panels for such shelving modules is advantageous for the purpose of both decoration and exclusion of dust and can be accomplished by means of snap-in panels without adding greatly to the cost or weight of the units. Sliding door panels have the advantage of appearance but unless they are removed from the channels, access to the entire shelf opening is not available. The use of hinges on doors for modules of this type requires the modification of the support members, adds to the expense and increases the difficulty in assembly and at the same time the doors project before the unit in their open position.

It is an object of this invention to provide a shelving module with doors for one or more of the shelf openings wherein the doors hang before the opening in the closed position and can be lifted or pivoted and pushed back into an open position into adjacency with the bottom wall of the shelf from which they are hung. Another object of the invention is to eliminate the disadvantages of previous type sliding doors while gaining new advantages.

SUMMARY OF THE INVENTION This invention concerns the provision of a bracket or hanger member adapted to be affixed between existing comer fastenings of a shelf module, and a front opening hook member that functions as a sliding guide for the door along the hanger and automatically hooks into the end of the hanger upon pulling the door outwardly whereby a hinge or pivot point is provided for the door. The hanger of this invention is universal so that it can be used at either end of a shelf. A hook and guide means is also provided forward of the front opening hook which extends inside of and under the hanger member to prevent the rear or top edge of the door panel from striking against the underside of the shelf under which it nests and also provide a holddown for the rear edge of the door so that in a partially open position the extended horizontal portion of the door becomes a temporary shelf or writing table.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2 an illustrative shelf module or unit 10 is shown to comprise the corner support members 12 holding a plurality of horizontal shelves l4 and having suitable channels to receive the removable back panel 16 and the side or end panels 18. The

panels

16 and 18 can be constructed of any suitable planar material such as fiber board, plastic laminates, plywood, etc. with or without trim or wood grain finish, or can be in the form of a lattice work, screen or perforated metal sheet. Any suitable means can be used to hold the panels in position.

The shelves 14 are preferably identical and two or more shelves can be used attached at their four comers at any desired spacing or elevation between the comer support members 12. The latter are provided with suitable spaced apertures 20 or slots (FIG. 6) to receive the corner clips or fastenings 22 which are held by means of the fastening screw or bolt 24 to the supports. The clips 22 can be of any of several known designs and the one shown engages across the inside corner of the shelf 12, against the planar top 26 by means of the boss 28 and into the side or end flange 30 by means of the upstanding tab 32 fitted within a suitable slot in the bottom rounded edge of the flange and by means of a similar upstanding tab, as at 34, into a slot in the bottom of the front (and rear) box flanges 36. The rolled constructions of the box flanges 36 is shown in FIG. 9 to include the inner wall 38.

The shelf comers are notched so that the ends of respective flanges abut against the inner corner walls of the comer supports in a rigid manner. Since the foregoing parts do not form a part of this invention, except as they may cooperate with the parts to be described, there is no reason for a more detailed description. It suffices to point out that the improvements of this invention can be used with any of a large variety of shelving units including flanged shelves, screw-fastened corner clips and spaced upright corner supports.

Referring to FIGS. 1 and 2 it is seen that the door or enclosure 40 is provided in the form of a planar essentially rectangular panel member having the straight bottom edge 42 and side edges 44 with a finger aperture as indicated at 46. The door 40 can be constructed of the same materials as the

panels

16 and 18. Wood grained plastic or wood laminate is preferred for strength, scratch resistance, lightness and beauty. The door panel 40 is shaped to conform with the front opening defined by the support members 12 and the adjacent shelves 14 such that in its closed position shown in FIG. 2, the opening is substantially enclosed. A slight clearance space is provided between the side edges 44 and the supports 12, so that the door can be moved in and out along a plane parallel to the shelf 14 upon or under which it is hung and also hung downwardly to a position wherein its edge 42 is in proximity to the top of the box flange of the next lower shelf as will be described.

In order to provide the aforementioned reciprocating and pivotal movements for the door 40 a bracket and hanger arangle that the plane of the rangement, such as shown in FIGS. 3 to 9, is fitted between the top edge 48 of the door 40 and the clips 22 front and rear of a given shelf. The hanger 50 is shown in FIG. 3 to comprise the essentially straight, elongated section 52 having the offset portions 54 at each end and depending in the same plane, depth and direction, the reverse portions 56 (also substantially equal in length, etc.) and the upright portions 58 (likewise uniform) with the bifurcated tabs 60 aflixed to the upper ends. As before stated the elongated portion 52 of the hanger 50 is preferably straight and the offset portions are substantially normal thereto and coplanar with each other. The tabs 60 are set at any angle so as to be engaged by the screw 24 of the front and rear clips 22 of the shelf from which the door panel 40 is hung. In the illustrative embodiment (FIG. 6) the clip 22 has a central flat portion 62 against which the screwhead and washer press in holding the shelf to the comer support. The surface 62 is at an angle (outside) of about 135 tothe plane of the side flange 30. Conversely, the internal angle defined between the plane of the flat portion 62 and the plane of either the front flange 36 or the side flange 22 is about 45. The bifurcated tab 60 is set at an angle to the vertical plane of the hanger 50 that bears this same relationship so that the tabs fit flush against the surface 62 of the clips. This angular relationship is apparent in FIG. 12. The hanger 50 is uniform or double-ended so that it can be used with either end attaching to a given support member and clip. Stated in another way the tabs 60 intersect the longitudinal axis of the hanger at the same clip intersects the planes of the flanges of the shelf. t

Preferably the tabs 60 are press fitted or welded on the upright portions 58 so that they do not rotate and form a rigid support. The hangers are fabricated in different lengths for difl'erent widths of shelves,-e.g. for inch, 12 inch or 14 inch shelves, as governed by the distance between the clips 22 or the equivalent. The tabs 60, each have the open-ended slot 64 for engagement around the screw 24 and under the washer for securement of the hanger 50 between the two side corners as shown in FIG. 6 for the front comer post. The use of a slot 64 facilitates mounting the hanger between the clips without the necessity of removing the bolt or screw 24.

The door panel 40 has the upper corners cut out as at 66 and the elongated channel strip 70 is affixed along the inside of the top edge 48 by means of suitable rivets or screws 72. The strip 70 is also cutout as at 74 so that a comer opening 76 is provided. The other end of the strip 70 and the corner of the door panel (not illustrated) are similarly notched or cut out. The strip 70 can extend along the entire top edge 48 of the door panel or consist of two individual brackets of reverse configuration.

Extending from thecutout corner 74, as part of the strip, is the shank portion 78 which terminates at the side edge 80 of the door panel with the depending flange 82 (in the attitude shown in FIG. 5) having the outwardly projecting flange 84 that is wider than the thickness of the rod and offset 54. The flange 84 has the ear 86 extending forward (toward the bottom edge of the door) with its inner edge 88 substantially in or slightly outside of the plane of the edge 80 of the door so that the thickness of the flange 82 accommodates the curved corner 90 at the offset 54. It is preferred that the inside surface of the flange 82 be in guiding contact with the outer surface of the guide rod portion 52 on each side of the door so that there is little or no lateral or side-to-side play at the top edge of the door as it is opened and closed.

Referring to FIG. 6 it is seen that the clip 60 is engaged by the screw 24 and the rod portion 58 extends to a position below the bottom of the flange 36 so that the straight guide portion 52 of the hanger extends along the inside of and below the side flange 30. This same support relationship is provided at the other end of the hanger 50 as shown in FIG. 4 and is also provided at the other end of the shelf (not shown) only in reverse configuration. Thus the guide portions 52 become a sliding support running along and below each end of the shelf 12 and provide the space 92 between the outer surface of the door 40 and the shelf flanges. Also FIGS. 4, 5 and 6 show how the shank 78 rests upon the guide rod 52, the flange 82 engages over the outside of the rod 52 and the flange 84 extends outwardly under the lower-level of the guide rod by an amount equal to or slightly greater than the thickness of the rod. Stated in another way, the inside distance between the flange 82 on one end of a shelf and the flange 82 at the other end is just enough greater than the parallel distance between the respective guide rods 52 that a free sliding relationship exists, free from binding and the door 40 can be pushed under the shelf 12 as shown in FIG. 4, or to a position wherein the door is entirely under the shelf, given a shelf width to shelf spacing ratio of unity. 7

Referring to FIGS. 5 and 6 further it is seen that the ear or tab 86 is under the ofi'set 54 (on each side of the brackets) such that when the door 40 is pulled out beyond or to the right of the position shown in FIG. 5, the extended tab 86 passes under the ofi'set 54 and the forward edge 92 of the flange 82 strikes against the offset 54 at or near the comer 90, this actiontaking place at each top comer of the door. This stops the outward movement of the door and the edge42 can now be hinged downwardly to the position shown in FIG. 2. The tab 86 catches against the ofiset 54 as in FIG. 8 to allow this hinging action and the arrangement takes the position shown in FIG. 9 with the offset 54 in the space 94 provided by the ofiset of the flange 82'. In this position the top edge 48 of the door comes flush against the inside wall 38 of the front box flange 36 so that the door hangs firmly and without any tendency to pivot. The bottom edge 42 of an upper door, in the same closed position is adjacent to and inside of the top wall 96 of the front flange 36. The same relationship'exists between the bottom edge of the lower door panel 40 in FIG. 9 and a lower shelf. The clearance 98 need only be sufficient to prevent contact of the parts during use.

In FIGS. 10, 11 and 12 another form of bracket is shown wherein the channel strip 70 is modified by having the wider shank 78a from which extends a second tab 100 that is spaced by the notch 102 from the end 104 of the hinge-forming tab 86. This bracket is further modified in that the inner edge 88 of the tab 86 is spaced outwardly from the edge 106 of the shank 78a, to form the open-ended slot 108. The notch 102 is slightly larger than the diameter of the offset 54 so that the edges, e.g. 110 clear the offset when the edge 104 of the first tab 86 is still spaced from the inside of the offset, so that the top edge of the door can be raised within the limits of the space 92 and allow the hinge tab 86 to clear offset 54 to remove the door, or install same in reverse of these relationships.

Referring more particularly to FIGS. 10 and 11 the second tab 100 is seen to have, or be supported by, a depending flange 112 that extends downwardly (in the attitude of FIG. 11) a distance equal to or greater than the diameter of thickness of the guide rod 52. The second tab 100 is thus placed under the guide rod 52 and serves in all horizontal and sliding positions of the door 40 (as in FIGS. 4 or 10) to prevent the door from hinging at the edge 80, where it contacts the offset 54, and thus prevent the top edge 48 from striking the under side of the shelf. The second tab 100 also serves to stabilize the door in its partially opened positions when it is used as a temporary shelf.

When the door 40 is pulled out past the position shown in FIGS. 10 and 12, without lifting, the first tab 86 takes over its dual function of a stop and hinge. This modified bracket can be otherwise dimensioned without departing from these functions. It is to be observed that the spacing provided by the opening 108 places the first tab 86 in about the center of the ofiset 54 so that the parts are readily aligned in installing the door. The modified bracket can be used in installations where there is no upper or lower shelf. The bracket and hanger combination of this invention can be used to suspend and hinge a door within the opening defined by various forms of structures other than the support members and spaced shelves of the module shelving described. From this description it is apparent that the hanger 50 can be attached between and from other parts of the shelving module and can be located at various elevations between spaced horizontal shelves.

The arrangement can be used in cabinets, built-in closets, paneled walls and the like, having an opening in one side that can accommodate a door panel. The bracket and hanger parts of this invention can be fabricated from steel using the available stamping and bending equipment without the need of special tools. The slot 64 can open downwardly instead of laterally and the angle at which the clip 60 is placed on the upright portion 58 of the hanger can be changed to bring the clip into the proper relationship with releasable securing means 24. Thus the clip 60 can be in the plane of the section 56 or be at right angles thereto, as an illustration. Also the reverse bend section 56 can vary in length depending on the particular construction with which these parts are to cooperate. The notch or cutout comer 66 is only necessary where there is a corner clip 22 to be cleared as the panel hinges to its vertical position. The size and shape of the cutout comer can be varied as desired to meet this need and in some installations the cutout comer can be eliminated. An advantage of constructing the bracket 70 as one piece extending along the inner top edge of the panel is that it reinforces the panel along this edge and allows the use of lightweight functional materials in constructing the panels. The guide rods 52 serve as side supports for the door panel 20 in its open position under the shelf 14. In FIG. 12, the opening or notch 108 is exaggerated for purposes of illustration and the edge 88 can be nearer to the edge 80 of the door panel and even contiguous thereto. The comers such as 90 can be rounded if desired, The guide rod 52 or the contacting and rubbing surfaces of the bracket 70 such as the inside corner of the flange 82 or the upper side of the L-shaped flange 100, can be coated with a plastic material of high lubricity, such as the pigmentary product known under the trademark of Teflon-S, to increase the smoothness and ease of operation of the door panel.
