Description

[Detailed description of the invention] A. Field of industrial application The present invention relates to a lock device for a coin locker, and is particularly applicable to both the type that uses one coin or the type that uses two coins, as well as the paid type and the coin return type. This invention relates to a general-purpose lock device for coin lockers that can be used.

B. Prior Art There are two types of coin lockers: types that use one coin and types that use two coins, depending on their size and location. Furthermore, as the name suggests, coin lockers use coins for a fee, but if they are installed in public facilities such as public halls or libraries, a coin return system is often adopted. Conventionally, in most cases, different locking devices have been used for each of these different types of coin lockers, but some coin lockers that can be used for free and for a fee, as disclosed in Japanese Patent Application Laid-Open No. 58-92097, Lock devices have also been developed.

Therefore, the above-mentioned paid and free lock device is provided with what is called a passage closing member and an opening/closing member at the lower end of the coin passage, and during normal use, the passage closing member is hung downward to open the coin passage. ,
When used in a coin return type, the coin passage is closed with a bolt, and with this passage blocking member closed, the opening/closing member closes the coin return opening when the lock is locked, and opens when the lock is unlocked, making it difficult to use a coin locker. The coin is configured to be returned to the user when the key is inserted into the cylinder lock and the lock is unlocked.

C. Problems to be Solved by the Invention As described above, the lock device requires two members: a passage closing member that opens and closes the coin passage and an opening/closing member that opens and closes the coin return slot, and the passage closing member is manually operated. Two operations are required: one to open and close, and the other to automatically open and close the opening/closing member by locking/unlocking the locking device, and they are not linked to each other at all, so the configuration is complex and the operation is relatively time-consuming. Moreover, when the paid system is selected, that is, when the passage blocking member is open, there is the inconvenience that coins smaller than the prescribed coin cannot be returned to the user upon unlocking.

D. Means for solving the above-mentioned problems The present invention solves the above-mentioned drawbacks, and the master lock 2 and the customer lock 3 are attached to the front panel 1, and the coin input slot 4 and the coin return slot 5 are opened. Along with
Coin passage A from coin input port 4 to coin return port 5
In a coin locker in which a coin checker 32, a coin stopper 34, etc. are provided in the middle of the coin passage A, the coin passage A is connected to the coin 30.
coin passage A.
A coin regulating plate 31 having the same thickness or slightly thinner as the coin 30 is placed on the rear side of the upper coin slot 4 in the coin passage A when one coin 30 is used, while it is located in the coin passage A when two coins 30 are used. is removably provided so as to be removed from the coin passage A, and a coin return plate 36 is provided on the rear side of the coin return opening 5 below the coin passage A and is constantly biased by a spring 52 to a position where it exits from the coin passage A. is advanced into the coin passage A by the pressing force of the latch lever 12 against the repulsive force of the spring 52 when unlocking, thereby leading out coins smaller than the specified coin 30 to the coin return port 5,
When the lock is locked, the pressing force of the latch lever 12 is released and the coin 30 is pivoted so as to be withdrawn from the coin passage A and collected.Furthermore, when the coin return method is selected, the coin return plate 36 is moved by the repulsive force of the spring 52. It is configured such that the coin 30 is fixed so as to always advance into the coin passage A and guided out to the coin return opening 5.

E. Function When using the coin locker, even if a coin larger than the specified coin is attempted to be inserted into the coin slot 4, the coin stopper plate 40 at the upper end of the machine frame block 29 prevents the coin from being inserted, making it impossible to use the coin locker.

When a coin smaller than the specified coin is inserted into the coin slot 4, it passes through the coin stopper 34 that regulates the width and enters the coin return slot 5 by the coin return guide 37 and the coin return blocking piece 16 that is not in the blocking state. I was led back and unable to use the coin locker.

When you insert the specified coin 30 into the coin slot 4,
The balance type coin checker 32 is pushed up, and the engagement notch 42 of the coin checker 32, which is engaged with the pin 15 installed in the latch lever 12, is released from the pin 15 and becomes in a lockable state.
At this time, the inserted coin 30 is temporarily prevented from falling by the coin stopper 34, and the coin return plate 36 is pressed against the latch lever 12 as shown in FIG.
The coin passage A is closed by being pressed by a stopper 18. When the customer key 19 is turned to lock the coin locker, the coin return plate 36 is removed from the stopper 18 as shown in FIG. 11, the coin passage A is opened, and the coins 30 fall downward and are collected. At this time, the coin return opening 5 is in a state where the return of the coin 30 is blocked by the coin return blocking piece 16 of the latch lever 12.

In the case of a coin locker that uses two coins 30, the screws 41 fixing the coin regulating plate 31 are removed and the coin regulating plate 31 is swung upward from the state shown in FIG. 6 to the state shown in FIG. As a result, the coin regulating plate 31 is removed from the coin path A, so that the two coins 30 sequentially inserted from the coin input port 4 are temporarily prevented from falling in a state where the two coins are overlapped by the coin stopper 34. The subsequent operations are the same as described above.

Next, when selecting the coin return method, with the repulsive force of the coil spring 52 suppressed,
The coin passage A of the coins 30 is blocked by fixing the coin return plate 36 to the screw hole 13 of the machine frame block 29 with screws 54. Thereby, even after the lock is locked, the coin 30 is temporarily held by the coin return preventing piece 16 of the latch lever 12, and then guided to the inclined guide 36a of the coin return plate 36 and returned from the coin return opening 5.

F. Example An example of implementing the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a front plate having a master lock 2 and a customer lock 3 mounted above and below the center, respectively, and a coin slot 4 and a coin return slot 5 are opened at the top and bottom of the left side.

A master lock 2 attached to the front plate 1 is rotatably inserted into a lock seat 6 fixed to the front plate 1, and a mounting block 7 for attaching to the coin locker body is square-fitted on the back side of the front plate 1. It is fixed in place.

A customer lock 3 attached to the front plate 1 is rotatably inserted into a lock seat 8 fixed to the front plate 1, square-fitted with a swing block 9 on the back side, and engaged/disengaged at the center thereof. A pin hole 11 into which a pin 10 is inserted is bored.

The swing block 9 squarely fitted to the customer lock 3 includes:
A latch lever 12 is fixed to the base.

The latch lever 12 of the swing block 9 has a pin 15 connected to the latch 14 installed at the upper end thereof, and a coin return prevention piece 16 for blocking the coin return opening 5 on the side surface.
A stopper 18 that comes into contact with the left side plate 17 of the front plate 1 to limit the swinging of the swinging block 9 is also provided to project downward.

The latch 14, which moves in and out of the right side plate 20 of the front plate 1 by rotating the customer key 19, has a guide groove 21 opened upward, and a guide pin 22 implanted in the front plate 1 on the trajectory of the guide groove 21. Its movement is restricted by a receiving pin 23 that abuts the latch 14 on the lower side.

In addition, a pin 15 embedded in the latch lever 12 and a front plate 1 are provided to facilitate the insertion and removal of the latch 14.
An S-shaped reversing spring 25 is attached between pins 24 installed above the latch 14 on the back side of the latch 14.

Reference numeral 26 denotes a lock holding plate which is swingably supported by a stop pin 27 installed approximately in the center of the latch lever 12 and the swing block 9.
This is to prevent it from slipping out.

Reference numeral 28 denotes a machine frame plate which is continuously provided on an extension of the right side plate 20 of the front plate 1, and a machine frame block 29 shown in FIGS. 5 and 6 is fixed inside with screws.

The machine frame block 29 fixed to the inside of the machine frame plate 28 is molded from hard synthetic resin, and a coin passage A is formed between the machine frame block 29 and the machine frame plate 28, which has a gap through which two coins 30 can pass together. A coin regulation plate 31 that prevents double passage of coins 30 is pivotally supported on the rear side of the coin input slot 4 above the back side (the side facing the machine frame plate 28), and the top of the coin regulation plate 31 is pivoted. A coin checker 32 is rotatably supported on the lower front side by bearings 33, 33 protruding from the machine frame block 29, a coin stopper 34 is supported below the coin checker 32, and a locking pin is further below the coin checker 32. 10 mounting plates 35 are provided protrudingly, and a coin return plate 36 is provided.
is rotatably supported.

Further, on the back side of the machine frame block 29, a coin return guide 37 is provided protruding beside the coin stopper 34, and a notch 38 into which a coin return plate 36 is inserted is opened below.

Furthermore, a return coin receiver 39 is provided at the front of the lower end of the machine frame block 29 and projects from the lower end of the coin return opening 5 of the front plate 1.

Reference numeral 40 denotes a coin stopper plate attached to the coin input port 4 side of the machine frame block 29, which restricts the insertion of coins larger than a specified size.

In the case of a type that uses one coin 30, a coin regulating plate 31 having the same thickness as the coin 30 or slightly thinner is fixed in a horizontal position with screws 41 as shown in FIG. 30 coin stopper 3
4 and the coin regulating plate 31. Thereby, the coin passage A is adjusted by the coin regulating plate 31 to a gap through which only one coin 30 can pass.

At this time, the coin checker 32 has 30 coins.
It plays the role of moving the to one side.

In the case of the type that uses two coins 30, the coin regulating plate 31 is swung upward as shown in FIG. . Therefore,
Extra coins 30 can be inserted into the coin passage A by the thickness of the coin regulating plate 31, and two coins can be held in a superposed state at the same time.

The coin checker 32, which is rotatably supported on bearings 33, 33 of the machine frame block 29, is of a balanced type, and its tip extends into the coin passage A, and as shown in FIG. The combination notch 42 engages with the pin 15 of the latch lever 12, and prevents the customer key 19 from rotating when a coin 30 is not inserted. When the coin 30 is inserted and the tip is pushed out of the coin passage A, the coin checker 32 retreats and its engagement notch 42 comes off the pin 15.
The latch lever 12 is released and becomes lockable.

As shown in FIG. 9, the coin stopper 34 is rotatably supported by bearings 43, 43 protruding from the machine frame block 29, and a coil spring 45 is loosely inserted into a pin 44 planted in the machine frame block 29. , one side of the coin stopper 34 is pushed up by the repulsive force of the coil spring 45.

The coin 30 is held by the coin stopper 34 through a fixed claw piece 46 formed at the tip of the coin stopper 34 and an adjusting claw piece 4 which is adjustable and fixed to a long groove 47 at the base of the coin stopper 34 with a screw 48.
It will be held at 9. At this time, coin stopper 34
is pressed by the customer key 19 via the locking/disengaging pin 10, the tip of the adjusting claw piece 49 advances into the coin passage A, and the coin 30 is held between the fixed claw piece 46.
When a coin 30 is inserted and the customer key 19 is removed after locking, the pressure by the locking pin 10 is released and the coin stopper 3 is moved by the repulsive force of the coil spring 45.
The adjusting claw piece 49 of No. 4 is pushed up, and the adjusting claw piece 49 is removed from the coin passage A, and as a result, the coin 30 falls down the coin passage A and is collected.

As shown in FIGS. 2, 6, and 11, the coin return plate 36 is rotatably supported on bearings 50, 50 protruding from the machine frame block 29. The coin return plate 36 has an inclined guide 36a protruding from its upper surface extending into the coin passage A. It is always energized to the position where it exits from the coin passage A by a coil spring 52 loosely inserted into a pin 51 implanted in the machine frame block 29.

That is, in the case of a paid coin, the repulsive force of the coil spring 52 prevents its tip from advancing from the notch 38 into the coin passage A unless it is pressed by the stopper 18 of the latch lever 12 when unlocking. There is. On the other hand, when adopting the coin return method, the screw 54 is inserted into the screw receiver 53 of the coin return plate 36.
, insert the screw 54 into the screw hole 13 provided in the machine frame block 29 and fix it, and then remove the coin return plate 36.
The tip of the coin is advanced from the notch 38 into the coin passage A, and the coin 30 is guided to the coin return port 5 along the inclined guide 36a.

In addition, the coin stopper plate 40 of the coin slot 4 and the adjusting claw piece 49 of the coin stopper 34
is adjusted and used by changing the prescribed coin 30.

G. Effects of the invention As described above, the coin locker lock device according to the invention forms the coin passage A into a gap through which two coins 30 can pass, and the coin 30 is placed on the rear side of the coin slot 4 above the coin passage A. A coin regulating plate 31 having the same thickness or slightly thinner is located in the coin passage A when one coin 30 is used, and is removable so that it can be removed from the coin passage A when two coins 30 are used. Since the lock device can be freely changed to one coin or two coins by simply changing the position of the coin regulating plate 31, the production cost is low and the change operation is easy. In addition, it has the advantage of being less likely to break down, and because it uses a stacked storage system for two coins, it can contribute to reducing the weight and size of the entire lock device.

In addition, the present invention provides a coin return plate 36 which is always energized by a spring 52 to a position where it exits from the coin passage A on the rear side of the coin return opening 5 below the coin passage A, and when unlocking, the coin return plate 36 is pressed against the latch lever 12. The coin passage A resists the repulsive force of the spring 52 due to the pressing force.
Move it inward, and when locking, press latch lever 1.
Since the pressing force 2 is released and the coin 30 is collected by exiting the coin passage A, if a coin 30 smaller than the specified coin is inserted, it will be guided by the coin return plate 36 and the coin will be returned as is. It has the advantage that it is led out to the port 5 and automatically returned to the user.

Furthermore, a single coin return plate 36 opens and closes both the coin return port 5 and the coin passage A, which simplifies the configuration with fewer parts, and as long as the paid system is adopted, the coin passage A can be locked and unlocked. Since the coin return plate 36 is automatically opened and closed by the action of the coin return plate 36 upon operation, there is no need for troublesome operations such as bolting as in the conventional case.

Furthermore, the present invention can be easily changed to either a paid system or a free system since the coin return plate 36 only needs to be fixed with screws 54 when the coin return system is adopted.
