Description



BACKGROUND OF THE INVENTION

The present invention relates to cabinet or locker type structures. The present invention is particularly useful in hospital environments since it incorporates the shelf and drawer support intelligence disclosed and claimed in co-pending U.S. Pat. application, Ser. No. 79,890 entitled Drawer, Tray-Shelf and Supporting Structures Therefor.

As pointed out in the above cited application, versatility and economy are key factors in the design of hospital equipment. From an economic standpoint, it would be preferable that all lockers purchased for hospitals incorporate plastic tambour doors. Such doors can be very inexpensively made of plastic, and the means required to mount such doors comprises a simple track structure at each side of the door.

However, the use of tambour doors may not always be practical or desirable from the hospital's point of view. There may well be circumstances in which the hospital would prefer lockers with horizontally opening doors.

Presently, the hospital would have to satisfy these alternative requirements with two separate lockers. The need for purchasing two different types of lockers is not desirable to today's inflation pressed hospitals. Not only is it expensive to purchase two different types of lockers, but also it is expensive for a cabinet and locker manufacturer to be able to manufacture two completely different types of lockers.

SUMMARY OF INVENTION

The present invention provides alternate solutions by providing a locker whose sidewalls have intelligence for slidably receiving a vertically sliding door and which also have intelligence for receiving hinges. Means are provided whereby the sliding door can be removed, and means are provided on the sidewalls for operably receiving hinges. The hinges operably and releasably cooperate with the hinge mounting means on the sidewalls. At least one door includes means for cooperating with the hinges whereby the vertically sliding door can be replaced with the horizontally swinging door.

Another aspect of the invention comprises the unique cooperating latch and catch means whereby the door is maintained in a closed position. Each hinge comprises a generally horizontally oriented platform having a latch projecting upwardly therefrom towards the door. The latch comprises a resilient member projecting upwardly towards the door and having a lip thereon which juts back downwardly towards the platform. The door includes a catch positioned opposite the latch which projects rearwardly to a position between the platform and the catch and which hooks upwardly, defining a hook for mating engagement with the lip on the catch. When one desires to open the door, one merely applies a force thereto and the resilient member of the catch bends upwardly and rearwardly to allow the hook to slide past the lip of the catch.

These and other objects and advantages of the invention can be seen and understood by reference to the specification and appended drawings.

PREFERRED EMBODIMENT

In the preferred embodiment, the locker 1 includes intelligence for mounting a sliding tambour door 40 in the form of tracks 30 in sidewalls 20 (FIG. 1). Locker 1 also includes snap-on hinges 50 (FIG. 4) to facilitate the mounting of horizontally opening doors 70. Cross pieces 60 (FIG. 4) are mounted in apertures 21 near the top and bottom of sidewalls 20. A pair of hinges 50 then snap on to cross piece 60, one near each sidewall 20. Door 70 is carried between spaced top and bottom hinges 50 and includes a latch 76 (FIG. 5) for cooperating with a catch 55 on each of the top and bottom hinges 50 located adjacent each sidewall 20.

Preferably, the components of locker 1 are molded of some type of plastic which is rugged, sturdy, and readily cleanable. The plastic sidewalls 20 depend forwardly from each side of back 10 (FIG. 1). Each sidewall 20 includes integrally molded drawer glides 23 of the type disclosed and claimed in co-pending U.S. Pat. application, Ser. No. 79,890. Back 10 includes an outwardly and downwardly projecting hook 11 and rearwardly projecting feet 12 whereby the entire locker 1 can be hung on a rail secured to a wall or the like. Drawers, shelves, trays, and the like, can then be mounted in locker 1 by placing them between opposite sets of glides 23.

Each sidewall 20 includes a track 30 in which vertically sliding tambour door 40 is mounted (FIGS. 1 and 2). Track 30 comprises a groove or channel which is preferably integrally molded into sidewall 20. Track 30 extends from the top of each sidewall 20, vertically down almost to the bottom, where it bends around and extends rearwardly near the bottom of sidewall 20 and then curves upwardly near the back edge of sidewall 20 (FIG. 3). A bottom retaining notch 32 is formed by a jogging deviation in the forward face of track 30 near the bottom front corner, for the purpose of providing a means for holding tambour door 40 in an open position as shown in FIG. 1. Similarly, an upper retaining notch 31 is cut into the rear face of track 30 at the top thereof for holding tambour door 40 in a closed position as shown in FIG. 2. Referring to FIG. 1, it will be seen that tambour door 40 includes a flange 42 projecting inwardly from its top slat for purposes of hooking into upper retaining notch 31.

Tambour door 40 is itself comprised of a plurality of slats 41 (FIG. 2). While many types of conventional tambour type doors are acceptable, the preferred type is that which is integrally molded of flexible plastic material. Because of this one piece construction, the door is readily washable. The door is purposely molded with joints, of narrow cross section, between wider segments which constitute the slats 41.

Referring to FIG. 3, it can be seen that track 30 has an open end 33 at the top thereof. This facilitates the complete removal of tambour door 40 when it is desired to substitute horizontally swinging doors 70 therefor.

In order to facilitate the hanging of door 70, each sidewall 20 includes intelligence to facilitate the installation of releasably mounted snap-on hinges 50. Each sidewall 20 includes an elongated aperture 21 at the top front and at the bottom front thereof (FIG. 3). A slightly flexible plastic cross piece 60 can be snapped into the top apertures 21 and into the bottom apertures 21 of opposite sidewalls 20 such that they span the width of locker 1 (FIG. 4). Such cross pieces 60 provide added rigidity and stability to locker 1. In some installations, it may be desirable to use such reinforcing cross pieces 60, even though tambour door 40 is to be used rather than horizontally swinging doors 70. In either event, the snap-on hinges 50 can be snapped into position on each cross piece 60 adjacent each sidewall 20 (FIG. 4).

Each sidewall 20 also includes a longer elongated slot 22, just to the rear of aperture 21. The primary function of slot 22 is to effectuate economy in material by making it possible to use less plastic. Each hinge 50 is molded of plastic and comprises a generally flat platform 51 (FIG. 6) having a pair of spaced, slightly resilient channel walls 52 projecting from one face thereof (FIG. 5). Each channel wall 52 includes a channel lip 53, both channel lips 53 curving inwardly from channel wall 52 towards one another. Hinge 50 can be snapped over cross piece 60 with channel walls 52 embracing the edges thereof and with channel lips 53 over-lapping the bottom thereof to thereby provide a snug mechanical fit between cross piece 60 and hinge 50.

In order to facilitate the hanging of door 70, each platform 51 includes a hinge pin 54 projecting upwardly therefrom (FIG. 5). This could project from the same face of platform 51 as channel walls 52, but it is preferable from a structural standpoint that it project from an opposite face. In this manner, each bottom hinge 50 can be placed on top of cross piece 60 with channel walls 52 depending downwardly and hinge pin 54 depending upwardly. If hinge pin 54 and channel walls 52 were oriented on the same face of platform 51, then the bottom hinge 50 would hang from cross piece 60 rather than rest thereon and would have a greater tendency to be snapped off by the weight of door 70.

Of course, there is no necessity for constructing the top hinges this way since they do not bear any weight. However, economy dictates that a hinge suitable for use at the bottom adjacent one side be suitable for use at the top adjacent the other side. Thus, only two basic hinges need be manufactured.

Referring to FIG. 6, it can be seen that hinge 50 is generally L-shaped and that hinge pin 54 is located on a laterally extending portion 51a of platform 51. This allows one to hang door 70 in direct alignment with the edges 20a (FIGS. 1 and 2) of sidewalls 20 such that they provide coverage for edges 20a as shown in FIG. 4. Platform 51 is sufficiently long that laterally extending portion 51a does extend out in front of the edge of sidewall 20 when bracket 50 is mounted on cross piece 60. Thus, each hinge 50 is slid along cross piece 60 until it abuts sidewall 20, with the result that laterally extending portion 51a will be positioned in front of the front edge 20a of sidewall 20.

Door 70 is economically molded of a suitable plastic, such that it has a relatively thin cross section throughout. Thus, it includes an edge wall 71 extending around its entire periphery (FIGS. 4 and 7). Extending inwardly from each edge wall 71, in a generally vertical plane, is a boarder wall 72 which frames a recessed face panel 74. An inwardly projecting recess wall 73 joins boarder wall 72 with face panel 74. This series of peripheral walls, i.e., edge wall 71, boarder wall 72, and recess wall 73, disposed angularly with respect to one another, provide door 70 with structural strength and rigidity.

Each door 70 includes an aperture 75 (FIGS. 5, 7 and 8) which slips down over hinge pin 54. Hinge pin 54 extends through aperture 75.

The fact that edge wall 71 depends rearwardly from front boarder wall 72 renders it possible to design edge wall 71 of a sufficient width that aperture 75 can be included therein for accommodating hinge pin 54. Further, boarder wall 72 is made sufficiently wide, before joining recess wall 73, that an upwardly projecting hinge pin 54 does not run into or abut recess wall 73 when door 70 is mounted in place in the locker. While an aperture 75 is shown only at the bottom corner of door 70, it will be appreciated that such an aperture 75 is also included at the top edge wall 71 of door 70 adjacent the side edge of the door. Consequently, each door 70 can be hingedly mounted between each pair of spaced top and bottom hinges 50 by mounting the hinges 50 with their hinge pins 54 extending in through apertures 75 of door 70. Also, the doors 70 are all symmetrical in design such that a right hand door can be used as a left hand door merely by inverting it.

Each hinge 50 includes an integral catch 55 for cooperating with a latch 76 on each door 70 (FIGS. 5 and 7). While it may only be necessary to have one catch 55 and latch 76 for each door 70, it is preferable that such cooperating catch and latch members be positioned both at the top and at the bottom of each door 70 to insure their proper closure.

Catch 55 comprises a resilient member 56 projecting from the same face of platform 51 as does hinge pin 54 (FIGS. 5 and 6). Resilient member 56 projects upwardly in a direction towards the front of hinge 50, i.e., towards door 70. At a point spaced from the surface of platform 51 it juts back downwardly towards platform 51 to define a catch lip 57.

Latch 76 includes a resilient projection 77, projecting rearwardly from bottom edge wall 71 to a position between the surface of platform 51 and catch lip 57 (FIGS. 5 and 7). At that point, it juts upwardly defining a hook 78 which engages catch lip 57 to hold door 70 in a closed position. While this cooperation is not directly shown, it can be readily visualized by viewing the exploded view, FIG. 5.

By applying a slight outward pressure to the door 70, resilient member 56 will be bent upwardly and rearwardly, and hook 78 will slide past catch lip 57 such that door 70 can be opened. Some deflection may also occur in resilient projection 77 of latch 78. However, the fact that resilient member 56 is disposed at an acute angle to the horizontal plane through which door 70 is opened renders it more susceptible to such resilient bending motion.

Thus, locker 1 can be provided either with tambour door 40 or with horizontally swinging doors 70. If tambour door 40 is used, locker 1 can be closed by sliding tambour door 40 all the way up in track 30 and hooking flange 42 into top retaining notch 31. In order to open tambour door 40, it can be slid downwardly and up the back side of locker 1 until the leading edge of its top slat 41 can be hooked into lower retaining notch 32.

In order to change doors, tambour door 40 can be slid all the way up and out of the open end 33 of track 30. A cross piece 60 can then be inserted at the top and at the bottom of locker 1, utilizing elongated apertures 21 at the top and bottom of each sidewall 20. The hinges 50 can then be snapped on to cross piece 60 such that one hinge 50 is located adjacent each sidewall 20 at the top and at the bottom thereof. The channel walls 52 of each hinge 50 will embrace the sides of cross piece 60, and the lips 53 will overlap cross piece 60 to firmly hold each hinge 50 in place thereon.

The bottom hinges 50 will be oriented with their hinge pin 54 pointed upwardly and the top hinges 50 will be oriented with their hinge pins 54 pointed downwardly. Hinge pin 54 will be received in the holes 75 located in the wall 71 at the top and in the edge wall 71 at the bottom of door 70 near the side of door 70. In this manner each door 70 will swing freely horizontally on hinge pins 54.

In order to effectuate closure of the doors 70, the latch 76 on each door 70 will cooperate with the corresponding catch 55 which is an integral part of each hinge 50. The hook 78 of each rearwardly projecting latch 76 will be engaged by the catch lip 57 of each catch 55. By applying a slight outward pressure to the door 70, the resilient member 56 of each catch 55 will bend upwardly and backwardly, thus allowing hook 78 to snap past catch lip 57, thereby allowing door 70 to be opened.

Thus, this invention contributes a locker with increased versatility and use. The same basic locker can be manufactured for use as a swinging door locker or as a tambour door locker. This effectuates an economy in manufacturing and makes it easier for institutions to adjust to their changing requirements.

Of course, the above is merely a preferred embodiment of the invention and many changes and alterations can be made thereof without departing from the spirit and broader aspects of the invention.
