Still another object of this invention is to provide a stepped-like series of flanges which extend continuously around the peripheral area of the door serving as a seat for snug cooperation with a cabinet.

In accordance with the general features of this invention, there is provided in a door for use with a main cabinet body having a door opening defined by an outer edge on the body, including, a main door panel, hollow post-like members integrally positioned on opposite sides of the panel, one of the members housing latching means,

while the other of the members having hinged means at tachable thereto, and the door panel having a manually operable handle insert inset within the door adjacent the latching means for actuating the latching means.

Another feature of the invention relates to the locker door having a dished insert inset in the main rearwardly projecting portion of the door with a side wall of the insert apertured adjacent latching means and a manually movable handle in the insert having one end extended laterally through the aperture for actuating the latching means.

The present application is a continuation-in-part of my copending application entitled Locker Latching Door Construction, Serial No. 418,941, which is being abandoned.

Other objects and features of the invention may more fully appear from the following detailed description taken in connection with the accompanying drawings which illustrate an embodiment thereof and in which:

As shown on the drawings:

The reference character 10 designates generally the cabinet body or locker with the locker door 11 mounted thereon by means of hinges 12 positioned along the front vertical edge 13 of the locker 10 (Figure l). The locker body 10 and the door 11 lend themselves to economical manufacture from sheet metal. Air louvres or vents 14 are optically located on the locker door 11 above and below a novel inset handle assembly unit 15 which is positioned generally offset-but close to the opposite vertical edge 13:: of the locker 16;

It will be noted that the novel locker door 11 (Figures 1 to 5, inclusive) is or" a new type that overlaps the front edge 16 of body 10 on each of its four sides and in such a manner as not tobe wholly inset within the locker opening 0 but rather to overlap the edge 16 and extend beyond the confines of the door opening 0. In this respect, my locker distinguishes from the type of locker now on the market in which the door and its latch mechanism are wholly inset in the door opening.

Figure 2 shows diagrammatically how my locker door 11 appears prior to the deformation of the peripheral areas of the door. Subsequently, the flange areas 11a are turned under as indicated by the score lines (Figure 2); the development of the flange areas llla being more clearly seen in Figures 3, 4 and 5. Thereafter, the inset handle assembly unit 15 and the latching mechanisms are assembled on the door 11 (Figure 1).

Along the outer peripheral margin of the door 11 (Figure 4) is an integral turned under continuous stepped flange 17 which is so formed as to abut the continuous stepped locker edge 16 along the leg or surface 18 of the flange 17. Secured to the rear side of the locker door 11 is an L-shaped flange 19 having a looped terminal end,

handle 25' mounted in a flanged and dished inset -26.

This inset 26 comprises a generally rectangular stamping extending rearwardly through an opening 26a in the door andalso concealing the edge of such opening. As best shown in Figure 7, the flanged edge of handle inset 26 and: showing my hinge assembly and also showing in has opposite deformed tabs 27 extending rearwardly through concealed suitable apertures in the door front for firmly securing the inset to the door.

Fitted around the rear surface of the fixed dished inset 26 .on the rear of the door is a dished plate 28 movable up and down with the handle 25 upon manual actuation of Same. The plate 28 has ,an apertured side flange 29 (Figure 4) extending over the curved margin of the dished inset 26 and terminates on opposite sides in aligned flanges or tabs 3030 slidably engaging the rear surface of the locker door 11 about the inset 26. It should be noted that in a vertical direction dished plate 28 is larger than the dished inset therein 'so as to be movable vertically thereon.

The dashed inset 26 has slots 31-31 aligned with apertures 31a-31a in flange '29 of plate 28 for receiving handle extensions 32-32, one of the extensions terminating in a rearwardly bent angular end 33 abutting on the outer surface of the flange 29 and the other extension 32 being bolted at 24 to the angular arm 23. Thus, it will be observed that that dished plate '28 is embraced on one of its vertical sides by angular handle end 33 and on its other side by angular arm 23.

Now, since the dished inset 26 is fixed to the door, whereas dished plate 28 is vertically movable by and with handle 25 over the rear surface of inset 26, opposite slots 31-31 in the inset 26 must be elongated, as is clearly shown in Figure 6, in order for handle extensions 3232 to move up and down in slots 3131. However, in the case of opposite apertures 31a-31a in dished plate 28, the handle extensions 32-32 snugly extend tlierethrough so as to move plate 28 with manually movable handle 25.

The advantage of the foregoing described handle assembly unit resides in the fact that by virtue of the handle slots 3131 being in the sides of dished inset 25, they are not readily visible from the front of the locker and hence do not detract from the frontal streamlined appearance of the locker. In addition, the slots 31-31 are not readily accessible for the insertion of a tool by one interested in tampering with the latch mechanism.

The plate 28 also has a vertically downward projecting extension 34 (Figures 6 and 7) with a laterally forward projecting integral lock tab 35 which passes through the slot 36 of the locker door .11 and into an outer enclosed tab receiving member 37. The member 37 is secured from within the slot 36 to the locker door 11 by deformed divergent tabs 38--38. The member 37 also has an aperture 39 therethrough and aligned with a similar aperture 40 in the tab 35 when the tab 35 is in its normal closed position in order to receive a padlock (not shown) such as is customarily used on lockers.

From the foregoing description, it will now be clear that upon actuation of the handle 25, the plate 28, the tongue flange 23, and the tab 34 will all move in unison so as to perform their various functions. I shall now proceed to describe the latch bar assembly.

Disposed within the box-like cavity 21 (Figures 4 and 8) defined by the offset margin of the locker door 11, the underturned stepped flange 17 and the L-shaped flange 19, is a vertically movable U-shaped or channelled latch bar 41 running the vertical length of the locker door 11 entirely outside of the confines of locker door opening 0. At a point intermediate its length, it has an aperture 22' aligned with aperture 22 and the edge of which aperture 22 is engageable by handle arm 23 for moving the bar vertically.

Displaced and suitably secured in vertical spaced relationship on the latch bar 41 are spaced compression springs 42 (only one being shown (Figure 7)). Suspended from each of compression springs 42 is a vertical extending U-shaped or channelled catch keeper 43 apertured at 44 and which aperture is aligned with an aperture 45 in the flange leg 18 in order to receive a catch member 46 attached to the locker edge 16 (Figure 4). It will be appreciated that spring 42 continuously urges the catch keeper 43 downwardly against catch member 46, thus making it difiicult for a tamperer to open the locker by shaking the catch keepers out of locking engagement.

In Figure 1, I have shown by dotted lines four sets of catches and keepers although it will be understood any suitable number can be employed. However, in each instance, the'keeper 43, together with the associated compression spring, constitute a lost motion connection between the catch and the latch bar 41; the extent of the lost motion being determined by the extent the spring 42 may be compressed. This is advantageous since, if one keeper or catch fails to operate in latching the door, it will not interfere with the operation of the others. In proper latching operation of bar 41 by handle arm 23, all keepers will function together. The up movement of the bar 41 will, of course, release the keepers from the catches, Whereas the downward gravitation of the bar will engage the keepers with the catches when the door is closed.

Upon actuation of the handle 25, the arm 23 causes the latch bar 41 to be lifted upward, while contemporaneously the catch keeper 43 will be raised by the compression spring 42, causing the catch keeper apertnred edge 47 to be disengaged from the catch member 46 and upon a slight outward pull, the locker door 11 may be opened.

Now, referring to hinges 12 (Figure 5 it will be noted that the hinged side of the door also has a stepped underturned flange 48 integral with the locker door 11 and an L-shaped flange 49 having a looped terminal end 49a, flange 49 being secured to the rear side of the locker door 11, and end 49a being secured to the stepped flange 48 at 50. The flange 48 can, if it is so desired, although not necessarily so, be made as an integral continuation of angular flange 16 on the opposite side of the door and may likewise extend around the top and bottom of the door for seating on the edge of the cabinet defining door opening 0. Abutting the stepped flange 48 is an underturned continuous flange 16 extending from the cabinet body side wall 51 and which is similar to flange 19 on the opposite side of the door.

The triple thickness of metal at 20 and 50 in Figures 4 and 5, in reality, comprises a rectangular frame-like rearwar'd extension around the rear surface of the door and snugly fits inside of the door opening 0 in telescoping cooperation therewith when the door is closed (Figure 2). Obviously, when the door is thus closed the latch bar mechanism is completely outward and laterally to one side of the door opening but directly over the cabinet edge of margin defining the door opening.

While I have illustrated (Figure 1) the locker as having four hinges 12 of the pintle type and which are identical in construction, it will, of course, be appreciated that any suitable number may. be employed without departing from the spirit of the invention. As best shown in the exploded view of Figure 9, each hinge 12 embodies a lower hinge plate 52, an upper hinge plate 53 adapted to be superimposed thereupon, and a hinge pintle 54 extending through the turned pintle portions 55 and 56 of the plates 52 and 53, respectively, in the usual way. The lower plate 52 includes two angular legs 57 and 58 which, as best shown in Figure 5, are of such length and arrangement that they can extend through an aperture 59 in the corner of the cabinet and be suitably secured to the inner surfaces of the cabinet with the pintle portion 55 projecting forwardly from the cabinet and located substantially at the front plane of the door 11. Actually, the leg 58 is aligned with and secured to the inside surfaces of the side wall 60 of the cabinet and the angular leg 57 is at right angles thereto and secured to the inner surface of the cabinet marginal flange 16 defining the opening 0. Thus, in the case of each hinge, the weight of the door is carried by the lower hinge plate 52 which is, in turn, supportedby the locker cabinet.

Each of the upper hinge plates 53 includes a main leg 61 (Figure 9) and ears 62-62 at right angles thereto and substantially at opposite ends of the turned pintle p rt t,

Now, again referring to Figure 5, it Will be noted that the leg 61 of the upper plate as well, as the ears 62 are disposed wholly within the cavity defined by the flanges 48--49 and the locker door 11 proper. These legs are suitably anchored to the interior surfaces of this hollow corner post defined by the corner of the door with the turned pintle portion 56 projected outwardly beyond an opening 63 in the corner post so that the pintle portion 56 is aligned with the lower pintle portion 55 of the lower plate 52. This arrangement is such as to locate the pivot axis of the hinge substantially aligned with the side wall 60 of the cabinet and substantially at the plane of the outermost front surface of the door 11.

' Now, in Figure 5, I have also illustrated, by dotted lines, an adjoining cabinet 11, having a door positioned in bank arrangement with the above described cabinet as is common practice in the mounting of the lockers.

From this illustration, it will be perceived why it is neces sary to locate the axis of the hinge substantially at the outermost plane of the door so that upon the swinging of the door of one cabinet, it will not interfere with or strike the door of the adjoining cabinet in the bank.

It is only by virtue of the manner in which the legs of the lower hinge plate 52 are projected along the lateral side edge of the door to the extreme outermost corner of the door that it is possible to dispose the pivot axis in the proper locale. Needless to say, the angular arrangement of the legs of the lower plate 52 is such as to enable proper support of the plate 52 so that it can eflectively carry the weight of the door and minimize the likelihood of the springing of the door.

In conclusion, it should be evident that the disposition of the main body of the door 11 outwardly of the door opening'O with the margin of the door overlapping edges of the cabinet defining the opening occasioned a number I of problems particularly with regard to the hinging and latching of such a door to the cabinet. In the locker structure of my invention described above, all of the mechanisms of the handle insert, the latch bar, and the hinge structure cooperate in the attainment of the unitary result of enabling the locker door to be located as aforesaid properly hinged to one side of the cabinet and efiec- .tively latchable to the other side of the cabinet.

It will be understood that modifications and variations may be eflfected without departing from the scope of the novel concepts of the present invention.
