LOCKER
Abstract
The sides of the locker include tracks in which a vertically
sliding tambour door is mounted. The tracks are open at one end so
that the tambour door can be removed. A cross piece can be inserted
between the sides of the locker at the top of the locker and at the
bottom thereof. Hinges can be snapped on to the cross pieces, and
horizontal swinging doors can be mounted on the hinges. At least
one of the hinges for each door has a catch which cooperates with a
latch on the door so that the doors will stay closed.

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.
