Abstract
A vending machine having a vandal panel and main door that can be easily removed through upper and lower hinge assemblies without use of conventional fasteners and tools is provided. As a result, the depth of the vending machine is reduced.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is directed to a vending machine having a main door that is easily removable from the vending machine cabinet. More specifically, the invention is directed to a vending machine in which the main door can be removed without tools in order to minimize cabinet depth.
2. Related Art
In a conventional vending machine, the vandal panel is permanently attached to, and protrudes past the front of the cabinet. The lower hinge of the main door and the door lifter bracket rest on a base plate, which also extends past the front of the cabinet. Both of these features effectively increase cabinet depth, making it difficult, if not impossible, to locate the vending machine in a narrow passageway. Also, in a conventional vending machine, the upper hinge of the main door is held in place by five fasteners, and the inner door is mounted to the main door by two self-tapping screws. Removal of the main door from the cabinet requires removal of all five main door fasteners; and removal of the inner door from the main door requires removal of the self-tapping screws. Conversely, assembly of the main door to the cabinet and the inner door to the main door require re-installation of the fasteners and the self-tapping screws, respectively. Neither the fasteners nor the self-tapping screws can be removed or re-installed without the use of tools.
Although there are many examples of mechanisms designed to facilitate the installation and removal of doors and the like from cabinets, refrigerators, other enclosures, and support surfaces (see, for example, U.S. Pat. No. 5,806,144 to Fries; U.S. Pat. No. 5,265,954 to Keil; U.S. Pat. No. 5,193,308 to Davidian; U.S. Pat. No. 4,620,392 to Kerpers et al.; U.S. Pat. No. 4,099,293 to Pittasch; U.S. Pat. No. 3,478,383 to Brooks; U.S. Pat. No. 3,270,462 to Obadal et al.; U.S. Pat. No. 2,385,169 to Stone; U.S. Pat. No. 1,564,668 to Hageman; U.S. Pat. No. 1,012,606 to Davis; and Pat. No. 42,764 to Harrington), the prior art does not provide any such mechanism adapted to permit the installation and removal of a main door of a vending machine quickly and without tools. It is to the solution of these, and other problems, to which the present invention is directed.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a vending machine in which the vandal panel and the main door can be easily removed, particularly without the need to remove fasteners or use tools to effect removal of the vandal panel and the main door.
It is another object of the present invention to provide a vending machine in which the depth of the main door lower hinge is reduced.
It is still another object of the present invention to provide a vending machine in which the inner door can easily be removed from the main door.
These and other objects of the invention are achieved through provision of a vending machine having a selectively removable main door that is assembled to the vending machine cabinet by upper and lower hinge assemblies that omit conventional fasteners that require tools for their installation and removal.
The upper hinge assembly includes a hinge plate that is selectively engageable with the main door and an upper hinge latch mechanism that is installed in the interior of the cabinet and that selectively mounts the hinge plate to the cabinet. The upper hinge latch mechanism includes a spring-biased plunger that is normally biased to engage the hinge plate. The lower hinge assembly includes a hinge base that is also selectively engageable with the main door and a lower hinge latch mechanism that is installed in the interior of the cabinet and that selectively retains the hinge base in the cabinet. The lower hinge latch mechanism includes a spring-biased pin that is normally biased to engage the hinge plate.
In one aspect of the invention, an inner door is provided over the inner face of the main door. An inner door hinge assembly hinges the inner door to the hinged side of the interior face of the main door along one side thereof and permits selective removal of the inner door from the main door without the use of tools or the removal of fasteners.
In another aspect of the invention, a vandal panel is positioned to cover the facing edges of the hinged sides of the main door and the cabinet when the main door is in the closed position. The vandal panel has upper and lower ends engaging the hinge plate and the lower hinge assembly, respectively, and is removable therefrom without the use of tools or the removal of fasteners.
In still another aspect of the invention, a door lifter mechanism is provided for supporting the weight of the main door while the main door is in the closed position, and for compensating for any sagging of the main door that may occur. The door lifter mechanism comprises a door lifter extending outwardly from the inner face of the main door and a door lifter bracket positioned in the cabinet to receive the door lifter bracket when the main door is in the closed position.
Other objects, features and advantages of the present invention will be apparent to those skilled in the art upon a reading of this specification including the accompanying drawings.

and an external portion
140
extending outwardly of the guide channel
136
. A main door lower hinge pin
142
is affixed to the free end of the external portion
140
. The upper face
140
a
of the external portion
140
provides a lower support surface for the flange
52
of the vandal panel
40
. Proper positioning of the flange
52
is ensured by a projection
144
on the upper face
140
a
of the external portion
140
, which engages an aperture
146
in the flange
52
.
The hinge base
132
is removably retained in the cabinet
12
by a latch mechanism
150
. The latch mechanism
150
includes a latch housing
152
inserted into an aperture
154
in the right side panel above the guide channel
136
, a vertically-oriented coil spring
160
positioned in the housing, and a vertical latch pin
162
inserted in the coil spring
160
and having its upper and lower ends extending through aligned apertures
164
in the top and bottom of the latch housing
152
and a corresponding aperture
166
in the hinge base
132
. The latch housing
152
is attached to the left cover panel by fasteners
170
such as four self-tapping screws. A horizontally-oriented dowel
172
is inserted through the latch pin
162
and provides a lower bearing surface for the coil spring
160
to normally bias the latch pin
162
in a downward position. Downward travel of the latch pin
162
is limited by an e-clip
174
inserted into a circumferential groove
176
in the latch pin
162
below the dowel
172
.
Should the vending machine
10
be overturned, the downward bias provided by the coil spring
160
will hold the latch pin
162
in position. However, the dowel
172
can be used to lift up the latch pin
162
to release the hinge base
132
from the guide channel
136
. Once lifted, the dowel
172
can also be rotated so that one end engages a notch
180
provided in the back of the latch housing
152
, to retain the latch pin
162
in the upward position in engagement with the aperture
166
in the hinge base
132
.
As in a conventional vending machine, the interior face of the main door
60
of the vending machine
10
in accordance with the invention is provided with an inner door
182
. However, to provide ease of handling, and to eliminate some of the bulk resulting from having the inner door
182
attached to the main door
60
during removal of the main door
60
, the inner door
182
of the vending machine
10
in accordance with the present invention is selectively removable. To this end, the top of the inner door
182
is hinged to the main door
60
by a conventional fixed pin
184
, and the bottom of the inner door
182
is hinged to the main door
60
by a removable hinge pin assembly
190
.
The hinge pin assembly
190
comprises a hinge bracket
192
mounted to the inner face of the main door
60
, a vertically-oriented coil spring
194
positioned in the housing, and a vertical hinge pin
196
inserted in the coil spring
194
and having its upper and lower ends extending through aligned apertures
200
in the top and bottom of the hinge bracket
192
and in the bottom of the inner door
182
. The hinge bracket
192
is attached to the main door
60
by fasteners such as two self-tapping screws
202
. A bushing
204
is inserted into an aperture
206
in the inner door
182
to act as a guide for the hinge pin
196
. The hinge pin
196
is provided with an operating handle
210
that functions as an upper bearing surface for the coil spring
194
to normally bias the hinge pin
196
in an upward position. The operating handle
210
can be used to depress the hinge pin
196
to release it from the inner door
182
. Once depressed, the operating handle
210
can also be rotated so that it engages a notch
212
provided in the side of the hinge bracket
192
, to retain the hinge pin
196
in the depressed position.
The vending machine
10
is provided with a door lifter assembly
220
to support the weight of the main door
60
while closed, and to compensate for any door sag that may occur. The door lifter assembly
220
comprises a door lifter
222
and a door lifter bracket
224
. The door lifter
222
is mounted on the lower inside corner of the main door
60
, on the non-hinged side. The door lifter bracket
224
is inserted into an aperture
226
in the right side panel of the cabinet
12

is generally rectangular, but necked in at the bottom to define shoulders
322
which engage the notches
316
of the latch
310
. The tab
314
extends outwardly from the aperture
320
.
The bottom hinge assembly
250
is assembled as follows. The tabs
292
of the opposed side walls
290
b

provides a finger hold for removing the bottom hinge plate
260
when it is fully inserted into the notch
274
of the right panel
22
of the cabinet
12
.
The rear hinge pin
280
supports the weight of the main door
60
and acts as a guide for inserting the bottom hinge plate
260
into the notch
274
. The top head portion
280
a

by welding, by providing a hole in the base plate
130
(not shown) and threads on hinge pin
280
configured to engage a nut
282
underneath the bottom wall
12
e
when the hinge pin
280
is inserted through the hole in the bottom wall
12
e
, or by any other suitable means.
When the bottom hinge plate
260
is positioned in the fully retracted position (FIG.

), its front aperture
268
a
is in registration with the longitudinal slot
296
in the upper wall
290
a
of the hinge guide
290
. Conversely, when the bottom hinge plate
260
is in the extended position (FIG.
10
), its central aperture
268
b
is in registration with the longitudinal slot
296
. In both cases, the lip
312
of the latch
310
will pass through the aligned slots and provide a positive engagement for the bottom hinge plate
260
to prevent it from “walking.”
The latch
310
is secured in place by a latch retainer
330
positioned against the side surface
22
b
of the right panel
22
of the cabinet
12
. The latch retainer
330
includes top and bottom ends

320
a
of the aperture
320
acts as a hinge point, allowing the latch
310
to pivot upwardly and downwardly against the bottom edge
320
a
. If the vending machine
10
were overturned and the latch
310
became disengaged, the rear hinge pin
280
would prevent the bottom hinge plate
260
from being pulled out of the vending machine
10
, and thus would prevent access to the inside of the vending machine
10
.
