This relates to a vending machine in which temporarily stored coins are stored in a safe, and with a particularly skillful operation after inserting coins, by pressing a return button, the inserted coins are returned and the door is opened. The purpose of this is to prevent people from taking the money for free.

Hereinafter, before showing one embodiment of the present invention, a conventional one will be explained. A decorative layer 2 is provided on the front surface of a main body 1 such as a refrigerator, and a storage door 3 is provided on the inner surface of this door 2. There is.

In the main body 1, an arbitrary number of product storage chambers 5 are provided by partition walls 4.
, 5... are formed, and the storage door 3 is provided with outlet doors 6, 6... and selection switches 7, 7... corresponding to the storage chambers 5, 5... ing.

Further, a coin input slot 8 and a return button 9 are provided at the upper part of one side of the storage door 6, and a coin sorting mechanism and the return button 9 are provided behind the coin slot 8.
Coin mechanism 1 including related coin return mechanism etc.
o is attached.

11 is a coin return slot. Next, the locking mechanism and unlocking method of each outlet door 6 will be explained.
A fixed guide member 12 is provided inside each of the
This guide member 12 has sliding openings 1 at three locations on the top and bottom.
3.13 is provided, and in the middle of these openings 13.13 is an actuating piece 1 of a lock release detection switch 14, which will be described later.
A window 16 facing 5 is formed.

Numeral 17 is a sliding lock operation plate which is superposed on the guide member 12 and has an L-shape as a whole.
8.18 are protruded and inserted into the openings 13, 13, respectively.

The center portion between the support shafts 18 and 18 is a recess 19.

Furthermore, above the bent piece 2o of the operation plate 17, there is a follower 2 of a lock solenoid 21 fixed to the guide member 12.
A locking hole 23 into which the locking member 2 is fitted is provided, and an upward locking hook portion 24 is integrally provided below.

The aforementioned lock release detection switch 14 is attached to a suitable fixed member, and its operating piece 15 operates when it enters the recess 19 of the lock operation plate 17 from the window 16 of the guide member 12 to collect money (not shown). A solenoid is operated to collect the temporarily stored coins into a safe.

On the other hand, a downward hook portion 25 that engages with the hook portion 24 is integrally provided on the back surface of the outlet door 6 .

To explain the operation in the above conventional configuration, normally the second
As seen in the figure or FIG. 3, the follower 22 of the lock solenoid 21 is fitted into the lock hole 23 of the lock operation plate 17, and the lock operation plate 17 is prevented from falling under its own weight.

Also, the hook portion 25 of the outlet door 6 and the hook portion 2 of the lock operation plate 17
4 are also engaged and are in a locked state.

When a specified number of coins are inserted into the input slot 8, the coins are temporarily stored in the coin mechanism 10.

Then, when selection switch 7 is pressed, lock solenoid 2
1 is activated, its follower 22 is pulled and comes out of the lock hole 23.

Then, the lock operation plate 17 descends due to its own weight, and at this time, the actuator 15 enters the recess 19 of the operation plate 17, and the lock release detection switch 14 is activated, which activates the collection solenoid (not shown) and collects the coins. When the money is collected, the hook part 25 of the outlet door 6, which was in the locked state, and the hook part 24 of the lock operation plate 17 are disengaged, and the outlet door 6 is locked.
can be freely released.

However, if we pay close attention to the above-mentioned series of operations, we can see that the follower 22 comes out of the lock hole 23, the lock operation plate 17 moves downward, and in order to operate the unlock detection switch 14, the lock operation plate 17 must move downward. Requires distance to travel.

Therefore, the lock operation plate 17 is moved by the follower 22 into the lock hole 2.
3, and in a state where the lock release detection switch 14 is stopped just before actuation, if the return button 9 is pressed, all the inserted coins are returned to the return slot 11.

In other words, the contents can be taken for free.

Normally, the hook portion 24 is integrally formed with the lock operation plate 17, and the hook portion 25 is also integrally formed with the outlet door 6.

Generally, the hooks 24 and 25 are locked by engaging with each other, and if you pull the outlet door 6 strongly as shown in Figure 4, the lock will become tighter and the lock will be operated. The downward movement of the plate 17 can be restricted.

Therefore, after inserting a coin, the lock operation plate 17 is lowered, and at the position just before the lock release detection switch 14 is activated, pull the ejection port door 6 strongly and temporarily lock the lock operation plate 1.
7 stops descending, then press the return button 9 to return the coins, and loosen the outlet door 6 again. The lock operation plate 17 descends, the hooks 24 and 25 disengage, and the outlet door 6 is opened.
It becomes possible to open it and take out the contents inside.

The present invention has been devised in view of this point, and will be explained below with reference to FIGS. 5 and 6.

Items that are the same as conventional items are given the same number.

The present invention provides a mounting piece 26 bent toward the storage door 3 at the lower part of the fixed guide member 12, and a support shaft 27 is provided perpendicularly to this mounting piece 26, and this support shaft 27 has a hook. A lock piece 29 having an upwardly facing lock piece 28 is rotatably supported.

The lock piece 29 is designed to rotate downward under its own weight, but by being supported horizontally, the hook piece 28 can be removed from the exit door 6.
from below.

Further, a through hole or a recess (not shown) is provided in the lower part of the guide member 12 so as not to obstruct the movement of the lock piece 29 when it rotates downward.

On the other hand, a support piece 30 is integrally provided at the lower end of the lock operation plate 17 and is bent toward the mounting piece 26 . The lock piece 29 is horizontally supported from below and engaged with the hook part 25 when the lock piece 29 is in the position.

Because of this structure, under normal usage conditions, when a coin is inserted, the selection switch 7 is pressed and the lock solenoid 21 is activated.
When the follower 22 comes out of the lock hole 23, the lock operation plate 17 descends under its own weight, and at the same time, the support piece 30 that supports the lock piece 29 also falls, so that the lock piece 29
rotates downward under its own weight as shown in Figure 6.

Therefore, the hook piece 28 of the lock piece 29 and the hook part 2 of the outlet door 6
5 is disengaged, and the outlet door 6 can now be opened.

At the same time, the actuating piece 15 of the lock release detection switch 14 enters the recess 19 of the lock operation plate 17, and the switch 14 is operated to actuate a collection solenoid (not shown) and collect the stored coins.

Here, when the outlet door 6 is pulled outward in an attempt to force the removal operation as in the conventional case, the hook portion 25 firmly engages the hook piece 28 and prevents the lock piece 29 from rotating downward. There is.

Therefore, when selection switch 7 is pressed, lock solenoid 2
The first follower 22 comes out of the lock hole 23, and the lock operation plate 17 descends together with the support piece 30 under its own weight.

That is, the lock operation plate 17 and the support piece 30 are connected to the lock piece 29.
Since it is separate from the hook piece 28, the lock piece 29 and the hook piece 28 can be lowered independently even if the lock piece 29 and the hook piece 28 are locked to the hook part 25.

Therefore, the lock operation plate 17 is connected to the lock release detection switch 1.
4 is activated, the collection solenoid is activated, and the temporarily stored coins are collected into the safe.

After this, the user presses the return button 9 and the inserted coins are not returned because they have already been collected.

When the pulling operation of the outlet door 6 is stopped, the lock piece 29 and the hook piece 28 are free from tension and rotate downward by their own weight, releasing the engagement with the hook part 25 and opening the outlet door 6. possible.

In this way, in this embodiment, even if a conventional pick-up operation is performed, the inserted coins can be collected, thereby preventing coins from being left behind.

As mentioned above, the main body is divided into a number of product storage chambers, each of which is equipped with a lockable exit door, and when coins are inserted, the coins are temporarily stored and a specified number of coins are stored. After turning on, the door is unlocked by operating the selection switch, etc.
Conventionally, in vending machines designed to collect coins when opened, the locking hook provided on the back side of the exit door and the other hook that engages are usually a lock solenoid and a guide. It is integrated with the lock operation plate that is prevented from descending along the member. During normal sales operation, the lock operation plate lowers a little and first activates the lock release detection switch, and this switch operation collects the money. After the mechanism works and the temporarily stored coins are collected, both hooks are disengaged and the extraction exit door can be opened, but after operating the selection switch, the lock operation plate descends until just before the lock release detection switch is activated. At this time, when you pull the ejection door, the engagement of the hook prevents the lock operation plate from lowering any further.Therefore, you can press the return button to retrieve the coins, open the ejection door, and take the product. It was possible.

However, in the present invention, the other hook member that engages with the hook on the outlet door side is a lock piece separate from the lock operation plate, and this lock piece is pivoted to the lower end of the guide member, while this lock piece Normally, a support piece is provided at the lower end of the lock operation plate to hold the lock horizontally so that the hook piece provided at one end engages with the hook part on the extraction outlet door side, and when the extraction outlet door is pulled, the support piece is Even if the engagement is strengthened, there is no way to prevent the lock operation plate from descending; the lock operation plate will naturally fall when the selection switch is pressed, and the lock release detection switch will be activated to first collect the temporarily reserved coins. When the outlet door is loosened, the lock piece rotates downward, releasing the engagement with the hook of the outlet door and opening the door.

Therefore, it is possible to provide a vending machine in which the conventional take-home operation is completely prevented and normal vending operations are established.
