Description
FIELD OF THE INVENTION
The present invention is directed to a publication vending machine configured to dispense a single newspaper and/or magazine at a time.
BACKGROUND OF THE INVENTION
Single newspaper vending machines are known in the art. Exemplary embodiments of such machines are disclosed in U.S. Pat. No. 4,458,658 to Israel. U.S. Pat. No. 4,140,242 to Muller et al and U.S. Pat. No. 3,768,695 to Pearson. In the Muller et al patent, a front hinged door
34
is unlatched by a coin release mechanism to provide access to the newspapers. When the door is unlatched, a newspaper dispensing device
90
becomes visible. A spring-loaded magazine located behind the device
90
brings the stack of newspapers to the level of a withdrawal gate
96
. When the door
34
is closed, lever
68
displaces a projection
84
so as to trip and release a lever
146
. The lever
146
is part of a mechanism that otherwise blocks the withdrawal gate
96
. An adjustment mechanism
94
, shown in
FIG. 5
of that patent, adjusts the height of a lower section
106
of the withdrawal gate, the upper section being part of the machine frame and being stationary. The lower section is provided with a pocket
112
for accommodating the user's hand. Withdrawal of a newspaper rotates separate shaft-mounted levers
116
,
118
forwardly. The lever
116
is arrested in the forward position by a lever
126
which moves over and rests on a stop
130
. The lever
118
then swings back to its original position, displacing a blocking lever
120
which is then spring-urged back to its original position so as to block the lever
118
from further forward displacement. When the hinged door
134
is closed, level
68
causes displacement of lever
146
and the lever
124
on which stop
130
is mounted thereby freeing lever
126
so that lever
116
can rotate back to vertical. A paddle on lever
116
displaces the blocking lever
120
, freeing lever
118
for subsequent operation.
The Pearson patent discloses a top loading machine of the type described in the Muller et al. patent. A narrow front access door
14
is locked and unlocked by a coin mechanism. The door
14
is swung open to gain access to the newspapers. A newspaper is withdrawn through a space between upper and lower gate sections
19
,
20
. The lower gate section
20
is secured to a plate
25
which is vertically reciprocatable in channels
26
,
27
by means of a suspension cable
21
wound around an adjustment shaft
22
mounted on the top gate section
19
. Newspapers are bulk loaded on a stack carrier
18
which is supported by a cable system as shown in FIG.
3
. The suspension system is responsive to opening and closing of the front access door. When the access door is open, a pawl
30
swings forward as a newspaper is withdrawn. After the newspaper is withdrawn, while the door is still open, the pawl
30
returns to its original position and a lever
51
engages and locks the shaft on which the pawl is mounted so as to lock the pawl in position and block withdrawal of the next newspaper. When the door is closed, a finger
14
L rotates lever
51
so as to release the pawl shaft. In a second embodiment of the machine, shown in
FIG. 7
of the patent, the access door
14
is removed. The dispensing mechanism in this embodiment comprises a fixed gate section
80
and an adjustable gate section
81
. The mechanism includes a bail coupled to a shaft
83
journaled in the machine frame. A pawl
82
depends from the shaft and is locked in position after removal of the newspaper by a linkage assembly including a toggle
90
which is controlled by the coin mechanism.
The Israel patent discloses a single newspaper vending machine. The vending machine includes an elevator unit for raising newspapers after a newspaper is dispensed. A dispensing mechanism controls dispensing of one newspaper per payment. A coin mechanism controls actuation of the dispensing mechanism when a suitable amount of coins are inserted into the machine.
Vending machines wherein newspapers are dispensed by semi-automatic operation are also known. For example, in U.S. Pat. No. 3,042,250 (Watlington) there is disclosed a vending machine provided with a bridge
25
and a shaft
27
on which sharpened fingers
33
are located. See
FIGS. 2 and 5
. The bridge is displaceable by the operator using an actuator mechanism having a handle
41
. During forward movement of the bridge the fingers engage the top newspaper in a stack and move it to a discharge slot. The stack platform coacts with vertical racks
16
and ratchet wheels
58
. Similarly, U.S. Pat. No. 3,114,475 (Etes) discloses a vending machine capable of semi-automatic operation wherein a linger
36
, which is mounted on a reciprocatable carriage impales the top paper in a stack and displaces the paper to a discharge slot.
Newspaper dispensing machines employing slidable dispensing mechanisms are also known, as disclosed for example in U.S. Pat. No. 1,886,694 (Kelly) and U.S. Pat. No. 3,708,087 (Schonthal). In the Kelly patent, an automatic dispensing operation is followed by manual withdrawal of the newspaper. A frame A is displaceable together with an operating head
42
(within which a coin control mechanism is located) with respect to a discharge slot
11
. See FIG.
3
. The frame is provided with rollers
34
which rotate when head
42
is retracted by the operator so as to feed a paper to slot
11
. The paper is then grasped and withdrawn by the operator. Conversion of a semi-honior dispensing machine to a single copy machine is disclosed in U.S. Pat. No. 4,174,047 (Owens). A release mechanism
36
includes a slide plate
38
displaceable through a slot
29
. The plate
38
is spring-coupled to a coin mechanism pushrod
23
. A jaw
53
is mounted below the plate
38
to grip the forward edge of a paper. The mechanism
36
is pulled forward bringing a newspaper with it, and the paper is then grasped and withdrawn by the operator. A single paper vending machine wherein locking mechanisms are moved into and out of the newspaper path is also known as disclosed in U.S. Pat. No. 4,067,477 (Chalabian).
Although the single copy vending machines disclosed in the above reterences are improvements over the popular honor-type vending machines, a need exists for an improved single newspaper/magazine vending machine which is economically feasible to manufacture and which protects the dispensed product from damage from weather.
SUMMARY OF THE INVENTION
A vending machine is disclosed for dispensing a single publication product at a time. The vending machine includes a housing with a front wall, back wall, side walls, top wall and bottom wall. A door is hinged to the front wall on the housing and forms part of a display case for displaying information regarding the product being dispensed.
An elevator is located within the housing and slidable from a position near the back wall toward the front wall. The elevator is adapted to contain a stack of products being dispensed.
A dispensing assembly is mounted within housing and forward of the elevator. The dispensing assembly includes a dispensing sled which is translatable from an upper position to a lower position. The dispensing sled is adapted to engaged a publication product located on the elevator and to slide the publication product toward a dispensing area located at the bottom of the housing.
An actuation arm is attached to the dispensing sled and pivotally mounted to the housing. The actuation arm projects outward from the front of the housing and is actuatable in a downward direction. The downward actuation of the actuation arm translates the dispensing sled downward.
A locking mechanism controls dispensing of a publication product.
The foregoing and other features and advantages of the present invention will become more apparent in light of the following detailed description of the preferred embodiments thereof, as illustrated in the accompanying figures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
While the invention will be described in connection with one or more preferred embodiments, it will be understood that it is not intended to limit the invention to those embodiments. On the contrary, it is intended that the invention cover all alternatives, modifications and equivalents as may be included within its spirit and scope as defined by the appended claims.
Referring to the drawings, wherein like numerals indicate like elements, there is shown in
FIG. 1
a single paper vending machine according to the present invention designated generally as
10
.
FIG. 1
actually shows one vending machine on a stand. The vending machine
10
includes a front door
12
which is hingedly mounted to a housing
14
via hinges
16
(shown in FIG.
2
). The housing
14
includes a front wall
18
, a back wall
20
(shown in FIG.
2
), two opposed side walls
22
, a top wall
24
and a bottom wall
26
(shown in FIG.
2
). The walls are attached to one another through any conventional means and are preferably attached so as to prevent water intiltration into the housing.
At least one of the side walls
22
includes a hinged service door
28
which permits access to the inside of the vending machine for loading and unloading articles to be dispensed and for accessing a coin mechanism. It is also contemplated that the entire side wall could operate as the service door. A lock
30
is preferably mounted to the service door to prevent access to the interior of the machine.
Referring now to
FIG. 2
, a side cross-sectional view of the vending machine
10
is shown. The vending machine
10
includes an elevator
32
which is mounted with the housing
14
and is translatable from a position near the back wall
20
of the housing toward the front door
12
. The elevator
32
includes a base
34
which is slidably mounted on one or more guide shafts
36
. Two guide shafts
36
are shown in
FIG. 2
, one positioned vertically above the other. The guide shafts
36
are attached to the back wall
20
of the housing
14
and extend forward to a dispensing assembly
38
. The base
34
includes holes near its sides through which the guide shafts
36
pass. The guide shafts
36
operate to guide the base
34
from a position near the back wall
20
forward toward the dispensing, assembly
38
. The elevator
32
is shown loaded with articles for dispensing (generally designated “A”) such as periodicals or newspapers.
A biasing member
40
, such as a spring, is located on each guide shaft
36
between the base
34
and the back wall
20
. The biasing member
40
is sized larger than the hole in the base
34
, thus resulting in the biasing member
40
being retained between the base
34
and the back wall
20
. The biasing member
40
biases the base
34
toward the dispensing assembly
38
and away from the back wall
20
. The biasing members
40
are chosen so that the initial compression on each spring when the elevator is unloaded (i.e., when the base
34
is empty and is in its position closest to the dispensing assembly
38
), provides a desired residual force toward the dispensing assembly
38
. When the elevator
32
is loaded, the weight of the articles cause the biasing members
40
to compress forcing the base
34
toward the back wall
20
. The biasing members
40
provide the requisite amount of contact between the articles A and the dispensing mechanism
38
.
As shown in
FIGS. 2 and 3
, the front door
12
is hinged to the front wall
18
via a spring
16
. The spring
16
is preferably a torsion spring which biases the front door
12
toward the front wall
18
. The front door
12
includes a handle
42
to facilitate opening and closing of the door
12
. The front door
12
also includes a frame
44
within which a transparent panel
46
is mounted. The transparent panel
46
can be made from glass, plastic or any other suitable transparent material, and is mounted to the frame
44
in any conventional manner.
As shown in
FIG. 4A
, a display frame
48
is attached to the inside of the front wall
18
and defines, in combination with the transparent panel
46
and the frame
44
, a display case
50
for retaining one or more articles which are being dispensed by the machine. The display frame
48
includes a rear wall
52
which is visible through the transparent panel when no article is contained within the display case
50
. The forward face of the rear wall
52
may include indicia for displaying a suitable message, such as the phrase “Sold Out”, when there are no longer any articles left to be dispensed.
As shown in
FIG. 3
, a recessed opening,
54
is formed in the bottom of the front door
12
and is designed to facilitate grasping of a dispensed article.
Referring again to
FIG. 2
, at least one rearwardly extending door latch
56
is attached to the back of the front door frame
44
and operates to lock the front door
12
to the housing
14
until all the articles A stored on the elevator
32
have been removed. The details of the door latch
56
and associated locking mechanism will de discussed below.
An actuation arm
58
is pivotably mounted to the back wall
20
of the housing
14
and extends through a slot
60
formed in the front wall
18
, preferably adjacent to the front door
12
. The actuation arm
58
preferably includes a hand grip
62
to facilitate grasping of the arm
58
. As will be discussed in more detail hereinafter, the actuation arm
58
controls dispensing of articles A from the machine
10
. The actuation arm
58
is adapted to be pivoted by an operator of the machine through a small arc from an upper initial position (shown in
FIG. 5A
which is a right side view of the machine) to a lower dispensing position (shown FIG.
5
B). One or more springs
64
are attached to the actuation arm
58
and the housing and are adapted to bias the arm
58
into its initial position (FIG.
5
A).
The actuation arm
58
is attached to the dispensing assembly
38
. More particularly, a linkage
66
is attached to the actuation arm
58
and to a dispensing sled
68
. The dispensing sled
68
is translatably mounted to the dispensing assembly
38
. The linkage
66
is designed to convert the arcuate motion of the actuation arm
58
into translation of the dispensing sled
68
. The translation of the dispensing sled
68
feeds the article located on the top of the elevator
32
.
Referring to
FIGS. 4A through 4C
, details of the operation of the dispensing sled
68
and the structure of the dispensing assembly
38
are shown. In the illustrated embodiment of the invention in
FIG. 4A
, the dispensing sled
68
includes two guide wheels (shown in phantom and identified by the numeral
70
) mounted on either side of the sled
68
. The guide wheels
70
are located within rails
72
that extend from an upper end of the dispensing assembly
38
to a lower discharge end
74
located in the recessed opening. The rails
72
(guide the sled
68
from an upper, initial position (
FIG. 4A
) to a lower dispensing position (
FIG. 4B
) at the discharge end
74
of the dispensing assembly
38
. The rails
72
are mounted to a fixed support
78
.
The dispensing sled
68
also includes one or more contact fingers
76
which are attached to the sled
68
. The fingers
76
extend rearward and downward as shown. The fingers
76
are spring biased into the position shown in
FIG. 4A
by a torsion spring (not shown). A stop
77
limits the backward swinging of the finger. The details of the construction and operation of the fingers
76
can be found in U.S. Pat. No. 4,458,658, which is incorporated herein in its entirety. The fingers
76
have sharp ends or tips and are designed and oriented to engage the forward facing surface of the top article on the elevator
32
.
A fixed support
78
is attached to the housing
14
and has rollers
80
rotatably mounted within idler bearings. The rollers
80
protrude through the back of the fixed support and are designed to contact the top article on the elevator
32
. The rollers
80
roll along the surface of the top article while it is being dispensed. thereby easing the sliding of the top article out of the machine.
FIG. 6
is a plan view of the dispensing assembly
38
taken along lines
6
—
6
in
FIG. 4A
, and shows the details of the fixed support
78
. The dispensing sled
68
is attached to the fixed support
78
through one or more springs
82
. The springs
82
bias the dispensing sled
68
into its uppermost or initial position (FIG.
4
A). When the actuator arm
58
is in its lowermost position (FIG.
5
B), the linkage
66
translates the dispensing sled
68
to its dispensing position (FIG.
4
B), thus, extending the springs
82
. When the actuation arm
58
is released, the extended springs (both springs
64
and springs
82
) force the arm and sled into their respective uppermost positions.
In order to prevent an article from slipping out of the machine prior to being dispensed, the present invention incorporates a blocking mechanism
84
shown in
FIGS. 4A and 6
. The blocking mechanism
84
includes at least one blocking lever
86
which is mounted to a shaft
88
. The shaft
88
is rotatably mounted within journals. More preferably, there is a blocking lever
86
mounted on either side of the dispensing sled
68
. Each blocking lever
86
extends through a slot formed in the support
78
. The blocking lever
86
and shaft
88
are prevented from rotating by a latch
90
which is also pivotally mounted to the support
78
. The latch
90
includes a recess which is designed to capture the blocking lever
86
to prevent it from pivoting. The latch
90
is biased toward the blocking lever by a torsion spring
92
.
When the blocking lever
86
is in its blocked or locked position (i.e., facing backward as shown in FIG.
4
A), the articles cannot pass downward into the dispensing area. Rotation of the blocking lever
86
downward from its blocked position is prevented by the latch
90
.
Attached to the dispensing sled
68
is a bracket
94
. As shown in
FIG. 7
, the bracket
94
includes a roller
96
which is mounted on a lateral edge. When an article is being dispensed, the dispensing sled
68
begins to slide downward. As the dispensing sled
68
moves downward, it translated the bracket
94
in the same direction. As the bracket
94
moves, the roller
96
contacts a cam surface
98
on the latch
90
. The movement of the roller
96
causes the latch
90
to pivot away from the blocking lever
86
and, at the same time, compresses the torsion spring
92
. When the latch
90
pivots far enough, the blocking lever
86
is released from the recess. Further translation of the dispensing sled
68
cause the bracket
94
to contact the blocking lever
86
, causing the blocking lever
86
and shaft
88
to rotate within the bearings, thus unblocking the dispensing area. A spring
100
is attached to the shaft
88
for biasing the shaft
88
back to its non-rotated position. Thus, when the dispensing sled
68
is translated back to its original position, the spring
100
causes the shaft
88
to rotate back, thereby moving the blocking lever
86
back into its blocking position. At the same time, the torsion spring
92
causes the latch
90
to pivot back to its original position, locking the blocking lever
86
in the blocked position.
Referring now to
FIG. 9A
, an actuation arm locking mechanism
102
is shown. The arm locking mechanism
102
is configured to prevent actuation of the arm
58
until the requisite amount of money has been deposited in the machine
10
. The locking mechanism
102
includes a coin mechanism
104
mounted within the housing
14
. The coin mechanism preferably includes a battery operated solenoid
106
. Coin mechanisms arc well known in the art and, therefore, only the specifics of the coin mechanism
104
as it relates to the present invention will be discussed. The solenoid
106
includes a plunger
108
which extends out of a solenoid housing
110
. An internal spring (not shown) biases the plunger
108
into its extended position. The solenoid
106
is operative for retracting the plunger
108
upon receiving a requisite amount of coins.
FIG. 9B
is an enlargement of a portion of the coin mechanism
104
and locking mechanism
102
. A trip lever or cam lock
112
is rotatably mounted to a locking bracket
114
below the solenoid
106
. The earn lock
112
includes a locking seat
116
and a cam surface
118
. The solenoid
106
is positioned such that the plunger
108
seats within the locking seat
116
when the plunger
108
is extended as shown.
A locking latch
120
is attached to the housing
14
and engaged with the actuation arm
58
. More particularly, the locking latch
120
is pivotally attached to latch bracket
250
. The latch bracket
250
is attached to a support rod
252
which is pivotally attached to the top wall
24
of the housing
14
. A spring
254
is attached to the locking latch
120
and a flange on the latch bracket
120
. The spring urges the latch
120
to pivot upwards (counter-clockwise) as shown in the figures. A contact pin
256
is formed on the actuation arm
58
and is located so as to contact the support arm
252
as shown in FIG.
9
A. The rotation of the actuation arm
58
urges the support rod
252
to pivot about its pivot point
258
and, thus, translate the locking latch
120
in the direction of the arrow. As shown, the locking latch
120
includes a detent
126
and a lip
128
.
FIG. 9B
shows the location of the locking latch
120
when it is in its locked position. As shown, a flange
130
on the locking bracket
114
is located within the detent
126
of the locking latch
120
. As such, lateral movement of the locking latch
120
is inhibited by the contact between the lip
128
and the flange
130
on the locking bracket
114
. Since the locking latch
120
is engaged with the actuation arm
58
, arcuate motion of the arm is inhibited and, therefore, the dispensing assembly
38
cannot be actuated.
FIG. 9C
illustrates the arm locking mechanism in the unlocked position. When a predetermined amount of coins are deposited in the coin mechanism
104
, the solenoid
106
is actuated, retracting the plunger
108
. Once the plunger
108
is retracted from the locking seat
116
on the cam lock
112
, the asymmetry of the cam lock
112
causes it to pivot about its pivot point
115
. As the cam lock swings clockwise about the pivot
115
, the cam surface
118
on the cam lock
112
contacts the locking latch
120
and the cam lock hits the stop
117
. At this point, lateral motion of the latch
120
will cause the latch
120
to hit the cam surface
118
and force it against the stop
117
. Since the cam lock
112
cannot pivot any further, the locking latch
120
is forced to pivot about its pivot point
260
on the latch bracket
250
. This results in the detent
126
moving down from the locking bracket
114
such that the lip
128
no longer engages with the flange
130
. In this unlocked position, the locking latch
120
is free to translate laterally. Consequently, the actuation arm
58
is no longer locked and is, therefore, free to rotate.
After an article is dispensed, the actuation arm
58
is spring biased back to its upper position. This causes the locking latch
120
to translate back toward the locking bracket
114
. As the tip end
132
of the locking latch
120
contacts the cam surface
118
, it forces the cam lock
112
to counter-rotate. As the cam lock
112
rotates counterclockwise, it compresses the plunger
108
until it springs back into the locking seat
116
. Further lateral movement of the locking latch
120
causes the tip end
132
to contact the flange
130
. This contact causes the locking latch
120
to rotate just enough to allow the flange
130
to fall within the detent
126
once again locking the actuation arm
58
.
As discussed above, the front door
12
has one or more door latches
56
that operate to lock the front door
12
to the housing
14
. More particularly, the door latches
56
are part of a door locking assembly
140
shown in
FIGS. 2
,
4
C,
10
,
11
A,
11
B and
12
. In addition to the door latches
56
, the assembly
140
includes a door lock pivot arm
142
which engages with a detent
144
formed in the door latch
56
(see, FIG.
10
). The arm
142
is pivotally mounted to a support bracket
146
which, in turn, is mounted to the housing
14
. A spring
148
biases the door lock pivot arm
142
into engagement with the detent
144
in the door latch
56
.
Referring now to
FIGS. 4C
,
11
A,
11
B and
12
, the door locking assembly
140
also includes a disengagement mechanism
150
. The disengagement mechanism
150
includes a rod
152
which extends across a portion of the rear surface of the base
34
. The rod
152
is preferably retained within one or more cages
154
that are mounted to the rear surface of the base
34
and which permit limited downward motion of the rod
152
. One or more slots
162
are formed in the base
34
adjacent to the rod
152
. The slots
162
are located in alignment with the fingers
76
on the sled
68
such that the fingers
76
extend through the slots
162
when there are no articles on the base
34
. The number of slots preferably corresponds to the number of fingers
76
.
The rod
152
is connected to two L-shaped links
156
preferably by two wires
158
attached to either end of the rod
152
. The L-shaped links
156
are pivotally attached an upper portion of the base
34
. One leg of each L-shaped link
156
is configured to extend through slots
160
forked in the upper part of the base
34
when the shaped links
156
are pivoted.
The operation of the door locking assembly
140
will now be discussed. After the last article has been removed from the elevator
32
, the fingers
76
slide into the slots
162
behind the rod
152
as shown in
FIGS. 4C and 11A
. The next actuation of the dispensing assembly
38
causes the finger
76
to slide the rod
152
downward within the cage
154
. The rod, in turn, pulls the wires
158
which cause the L-shaped link
156
to pivot. As the arm on the L-shaped pivot passes through the slot
160
, it contacts the door lock pivot arm
142
, causing it to pivot up and out
95
of the detent
144
in the door latch
56
(schematically shown in FIG.
11
B). At this point, the door latch
56
is unlocked.
When the door latch
56
is unlocked, compression springs located between the front door and the front wall
18
of the housing
14
cause the front door
12
to open a small amount (e.g., approximately 2 inches). The purchaser can then open the front door fully and pull out the last article contained within the display case
50
. The spring force of the torsion springs
16
will cause the front door
12
to close fully and the door locking assembly to re-engage with the door lock pivot arm
142
, once again locking the front door
12
.
Referring now to
FIG. 2
, in order to load the elevator
32
, the operator pushes the base
34
toward the back wall
20
compressing the springs
40
. The operator then engages an elevator lock to hold the base
34
near the back wall
20
until the loading process is complete. One embodiment of the elevator lock
200
is shown in FIG.
8
A. The elevator lock
200
includes a bracket
202
mounted to an inner wall of the housing
14
adjacent to the elevator. The elevator lock
200
also includes an L-shaped pivot arm
204
with the shorter segment of the L-shaped arm being pivotally attached to the bracket
202
. Rotation of the pivot arm
204
is limited by a stopping surface
206
which contacts the bracket
202
after the pivot arm
204
is rotated through a small arc. The stopping surface
206
is positioned so as to permit the longer segment of the L-shaped pivot arm
204
to protrude slightly beyond the bracket
202
and, thereby, prevent the base
34
from sliding past the bracket
202
.
In use, the operator retracts the base
34
and rotates the pivot arm
204
until it protrudes past the bracket
202
as shown in FIG.
8
B. The operator then loads the elevator
32
. Once the elevator
32
is loaded, the operator counter-rotates the pivot arm
204
thereby releasing the base
34
.
It is contemplated that multiple units of the vending machine described above can be stacked and/or arranged on a common base as shown in
FIG. 13
While the invention will be described in connection with one or more preferred embodiments, it will be understood that it is not intended to limit the invention to those embodiments.
