Patented Feb. 4, 1941 UNITED STATES PATENT OFFICE LOCKING DEVICE John B. OConnor, Aurora, Ill., assignor to Lyon Metal Products, Incorporated, Aurora, Ill., a

corporation of Illinois 17 Claims.

The present invention relates in general to a locker construction, and more particularly to a locker latching construction for selectively latching a locker door.

It is an object of the present invention to provide a new and improved latching structure for lockers, which is adapted to engage a keeper to retain the door in closed position and which comprises a unitary .latching element having opposed resiliently mounted latch configurations adapted to engage the keeper from opposite sides.

Another object of the present invention is to provide a latching structure, as above, wherein the latching means are so congurated as to po-sitively engage the keeper against a relative door opening movement, but which comprises inclined surfaces adapted to initially engage the keeper when the door is moved to closed position, which surfaces result from deforming a generally flat, resiliently arranged wall or ange at a predetermined point intermediate of its length.

A further object of the present invention is to provide a latch construction, as above, engageable with an -apertured keeper but having inclined surfaces arranged transversely of the plane of the keeper and adapted to coa-ct with the edges of the aperture to retract the latch portions from keeper engaging position when the latch or keeper is moved relatively transversely.

It is a still further object of the present invention to provide an improved one-piece integral latch unit, substantially enclosed on three sides for protection against unauthorized tampering.

Among other objectsof the present invention is to provide a relatively small, inexpensive latching unit adapted to occupy a relatively small space on the door of the lo-cker, and thus adaptable for mounting in a marginal molding or the like upon 01 the door, and to provide such a l'atching unit which may be mounted on a selectively actuable contro-l bar for release by relative movement with respect to the keeper.

Numerous other objects and advantages will be apparent from a consideration of the following specification and drawing which disclose a device constructed in accordance with the principles of the present invention, and in which Fig. 1 is a perspective view of a locker constructed in accordance with the present invention;

Fig. 2 is a detail perspective View o-f a portion of the free edge of the door of the locker shown in Fig. 1, portions being broken away to disclose the interior construction thereof;

Fig. 6 is a sectional View taken on the line 6 6 of Fig. 4.

Referring more particularly to the drawing wherein the present invention is disclosed more in detail, Fig. 1 shows a general view of a locker l0, embodying the principles of the present invention. The locker has the usual top, side and rear walls and a front opening, dened in part by the vertically extending angle members I2 and I. The opening or doorway is closed by a door I6, hinged to the angle member I2, as at I8. The angle member I4, forming the opposite door jamb, is provided with a pair of lugs 20 which extend forwardly into the space occupied by the door in closed position. As will appear hereinafter more in detail, the lugs 2U are adapted to be engaged by latching means mounted on shiftable control means 24 for selectively latching and unlatching the locker door in accordance with the will of the operator.

The lugs 20 have a portion of generally U- or channel-shaped section when viewed from above, as indicated in Figs. 5 and 6, one of the arms of the U-shaped portion terminating in a transversely projecting flange 26, which is welded or otherwise secured to the inner surface of the forward wall of the angle member I4. The other forwardly extending side arm 28 of each lug 20 is recessed, as at 30 (Fig. 2), to provide a keeper portion or latch engaging portion.

Attention is directed, to the fact that a buffer 32, of rubber or similar material, is supported in the U-shaped portion of the keeper lugs 20, as clearly shown in Figs. 5 and 6, each buffer being held in position by a suitable adhesive o-r by projecting portions interengaging with apertures (not shown) in the lug. As will hereinafter appear more in detail, the buffers 32 are so arranged as to be contacted by the edge portions of the door when this latter element is moved to closed position to absorb the impact thereof and properly position the door.

The locker door I6 in the present embodiment is made of sheet material which, along the free side edge thereof, is turned inwardly to form a longitudinally inwardly extending flange 34. At a point substantially spaced from the outer surface of the door this flange is again turned inwardly to provide a flange 36 parallel with the plane of the outer surface of the door, but spaced therefrom. In the enclosure thus formed is mounted a channel member 38 which is shown in the figures of the drawing and extends longitudinally of the edge of the door with the base portion of the channel section occupying the otherwise open side of the recess and the sides of the channel section bearing against the inner faces of the door and the parallel flange 36. The channel member or control bar 38 is secured in place with respect to the door by means of 'projecting deformed portions 40 in the flange 36 which engage in suitable slots 42. Thus the instant structure, while providing a substantially complete tubular closure adjacent the margin of the door, provides a bar or channel member 38 which is adapted for vertical movement with respect to the door, which movement is limited by the predetermined longitudinal dimension of the slots 42.

In accordance with the present invention any equivalent means may be employed to constrain the channel member for controlled slidable movement adjacent the margin of the door.

It will be apparent from the above disclosure that the channel member will be maintained by the force of gravity in its lowermost position with respect to the door. Means is provided for manually shifting the control bar 38 to relatively elevated positions, and comprises a control handle 43 conflgurated with manually engageable portions and having a pair of rearwardly extending flanges or projections 44. It will be noted that the handle 43 is mounted on the front face of the door I6, the projecting portion 44 extending through elongated slots or apertures 46 in the door and being rigidly secured to the channel member or control bar 38 by means of rivets 48. (See Figs. 2, 5 and 6.) A door handle 50 surmounts the control handle 43 and is rigidly mounted on the door I6 through the agency of a lug 52 and a machine screw 54.

The control handle may be manually engaged to lift the handle and correspondingly the control bar 38 upwardly for disengaging the latching mechanism, as will hereinafter appear more in detail, at which time the door may be opened by drawing upon the handle 50. A lug or projection 56, integral with the lower portion of the control handle 43, passes through a corresponding slot in the lower portion of the door handle 5D and is provided with an aperture 58 for accommodating a suitable padlock or any other conventional locking device (not shown). When such a locking device is engaged with the aperture 58 the control handle 43 will be retained in the lowermost position.

'Ihe elongated slots or apertures `46 accommodating the rearwardly projecting lugs 44 on the control handle are enclosed interiorly of the locker by means of the angle member 60. This angle member is of relatively elongated construction and accordingly forms an enclosure with the corner provided by the channel member 38 and the inner surface of the locker door, which is of sufficient extent to reside opposite the slotted apertures 46, regardless of any normally adjusted position of the control bar. The angle member 60 is, moreover, secured in the position shown through the agency of a flange portion 62, configurated as shown in Fig. 2, and fastened to the base portion of the channel member 38 through the agency of fastening means 64.

The rearward door flange 36, as viewed in the ilgures, as well as the adjacent wall of the control bar of the channel member 38, are apertured as at 66 and 68, respectively, to permit entry of the keeper and portions of the lugs 20 into the enclosure formed adjacent the margin of the door to permit engagement by the latching units 22, so that the keeper may enter freely at all times. Attention is directed to the fact that the aperture 68 in the channel member is of relatively considerable extent. Accordingly, when the door is in closed position the latch engaging portions of the lug are positioned interiorly of this enclosure.

The latchingunit 22 is mounted on the vertically shiftable bar or channel member 38 through the agency of fastening means 12 (Fig. 2). kThe latching unit is made of a single integral piecev of sheet stock bent in a generally symmetrical configuration to provide the central wall 14, .which is the wall secured to the control bar 38, and rearwardly extending parallel walls 16 projecting rearwardly along the upstanding side edges of the central wall 14. 16 adjacent their rearward edges are bent reversely to form the inwardly extending walls or flanges 18. Attention is directed to the fact that these Walls or flanges 18 are both vertically arranged in spaced relationship so as to accommodate the keeper therebetween when the door is moved to closed position. In other words the latching unit is mounted opposite the apertures 66 and 68, which permit entry of the keeper into the marginal enclosure.

The flange or wall sections 18 are, in accordance with the present invention, conflgurated to interengage the keeper, and particularly the aperture 30 therein, for the purpose of selectively retaining the door in closed position, and to this end attention is directed to the fact that these wall portions are at an intermediate point along their length distortedl oppositely inwardly, as at (Figs. 2 to 6).

Referring more particularly to Figs. 2, 5 and 6, it will be seen that the inwardly distorted portions are so proportioned that they are of increasing depth or displacement with respect to the walls or flanges 18. In other words, in forming the distorted portions 80 the sheet material of the walls or flanges 18 is displaced out of the normal plane thereof a maximum distance adjacent the forward or free edges of the said flanges. These distorted edges, accordingly, provide locking edges projecting oppositely and adapted to engage behind the forward edge of the aperture 30 in the keeper, as clearly shown in Figs. 2 and 5. The inclined configuration of the distorted portions 80, in addition, provides inclined rearward surfaces adapted to initially contact the forward edge of the keeper when the door is moved to closed position.

It will be apparent from the foregoing that the control bar, and accordingly the latching unit, will normally be maintained in lowermost position by the force of gravity. When in this position, closing of the door will permit the keeper portions 28 of the lugs 20 to enter into the marginal enclosure through the apertures 66 and 68 and to pass between the walls or flanges 18 of the keeper unit. At this time the keeper and the inwardly deformed latching portions 80 will be located in the same horizontal plane as shown in Fig. 3, and accordingly the forward edge of the keeper will initially engage the inclined rearward surfaces of the latching portions and spread them apart, as shown in Fig. 6, so that the keeper The side walls' zoA can pass therebetween. Ultimately, the door comes to rest with the aperture 30 opposite the deformed latching portions 80, which accordingly spring thereinto with their edge portions engaging behind the edge of the aperture 3l] to securely latch the door.

The latching mechanism may be released by grasping the control handle 43 and manually actuating it upwardly in the slots 56, thus bodily shifting the control bar 38 and the latching unit 22. Attention is particularly directed to the fact that the relative shifting of the latching unit with respect to the keeper is permitted by the inclined upper surfaces 82 of the inwardly distorted or deformed latching portions. In other words, in spite of the fact that the keeper comprises an aperture, these inclined upper surfaces 82 resulting from the preferred distortion of the latching portions, when moved upwardly, first contact the upper edge of the aperture 30 and subsequently are shifted outwardly to the position shown in Figs. 4 and 6, in which position the interlocking engagement between the latch and keeper is released so that the door may be freely swung open.

The present invention provides a simple, inexpensive and efficient latching device which is extremely resistant to unauthorized tampering and fully enclosed and protected.

The present latch structure, moreover, adapts itself to use in enclosed marginal portions which may be associated with the conventional type of locker structure and which may be completely enclosed therein. To this end the novel arrangement available in accordance with the present invention permits the provision of latching means occupying a relatively small space, while resulting in a latching engagement in vopposed directions so that unauthorized release of one of the latching members will not `permit opening of the door.

While the above preferred embodiment discloses the formation of latching portions by congurating a resiliently supported wall or flange with a transversely extending deformed portion of increasing depth, the present invention is not so limited, but contemplates the provision of various other equivalent deformed latching portions wherein a latch engaging edge or projection is presented to the keeper, in combination with inclined keeper engaging surfaces.
