Description

[Detailed Description of the Invention] The present invention relates to a lock for a coin locker, and its purpose is to provide a lock attached to a coin locker that can be used for a fee or for free at a company, hotel, etc., for example.

To explain an example in detail, when a coin locker equipped with the lock of the present invention is not in use, the key is inserted into the cylinder lock and the lock is left open.

The key cannot be removed or rotated in this state.

The locker user places the required items in the locker, closes the door, and inserts, for example, 10 coins into the coin slot of the original lock attached to the door.
When a 0 yen coin is inserted, the coin falls halfway and is stopped by the fall prevention metal fitting. Only in this state does the locking metal become movable and the key become rotatable.

When the key is rotated clockwise, the lock protrudes and becomes locked. At the same time, when the key is rotated to its maximum limit (90° rotation), the coin is released from the catch and falls into the tray or collection box. , the key can be extracted at this extreme position.

The locker user removes this key and stores it.

When a locker user wants to open this locker, he or she inserts the key and rotates it 90 degrees counterclockwise, and the locking fitting retracts, leaving the door open.

At this time, if the coin is free, the 100 yen coin that was initially inserted is taken out from the coin tray.

In short, in the case of a free 100 yen coin, it is used as a tool to operate the lock, and as long as it is of a certain shape, it is not limited to 100 yen coins, and it can be used as determined by the location where it is installed. It is also possible to use something.

To explain a specific example with reference to the figures, 1 is a coin locker, and 2 is an original lock attached to a door 3.

The lock 2 forms a box-shaped case 4, and on the front side of the case 4 is a cylinder lock 1 having a keyway 5 into which a key is inserted and a rotation shaft 6.
to fix.

A coin passage 8 formed into a U-shape in cross section is fixed in the case 4 and extends vertically from the top and bottom of the case.

A coin slot 9 is provided at the upper end of the coin passage 8.

10 is a locking metal fitting, the front end is a flat plate, and the rear end 11
has a U-shaped cross section, a slit 13 is formed in the bottom plate 12, and a shaft 14 fixed to the surface of the coin passage 8 is protruded into the slit 13.

The locking fitting 10 is guided by the shaft 14 and slides.

The side plate 15 of the lock fitting 10 extends long forward, and a slit 16 is bored near the front end of the side plate 15.
The tip of the lever 17 is engaged inside.

The lever 1T is rotatably fitted around the circumference of a fixed shaft 18 protruding within the case 4, and a spring 19 is wound around the lever 17.

The lever 1T biases the sliding movement of the locking metal fitting 10 in the direction of movement in and out by the spring force of the spring 19, and maintains the device after the locking metal fitting 10 is moved in and out.

The hook 20 is made of metal and is rotatably pivoted on a shaft 22 attached to the side plate 21 of the lock fitting 10.

The hook 23 is a spring provided to press the tip of the metal 20 (inner surface of the case 4), and the hook 24 is a claw protruding from the tip of the metal 20, and the tip thereof is a slit 2 bored into the coin passage 8.
Insert into γ.

Reference numeral 25 denotes a retaining portion cut into the lock fitting 10, and this engaging portion 25 is provided so as to engage with the tip of a lever 26 fixed to the rear end surface of the rotating shaft 6 of the cylinder lock 1.

The pawl 24 hooks onto an end 28 of a slit 27' formed in the coin passage 8 at the retracted position of the locking metal fitting 10, and prevents the locking metal fitting 10 from protruding or moving.

When a coin 37 is inserted into the slot 9 using the above structure, the coin falls through the coin passage 8 and falls into the stopper fitting 2.
The receiver is stopped at the tip 30 of 9.

When the key is turned clockwise in this state, the locking fitting 10 is driven by the lever 26, and at the same time, the hook 24 of the hook 20 attached to the locking fitting 10 passes over the rounded shoulder part of the outer periphery of the coin 3γ. In this state, the locking fitting 10 is removed from the end 28 of the slit 27', so that the locking fitting 10 protrudes outside the case 4.

The retaining metal fitting 29 is connected to a shaft 31 fixed to the inner surface of the case 4.
The tip portion 30 is pressed against the inner surface of the case 4 by a spring 32 so as to be engaged with the slit 27 of the coin passage 8.

For example, the shaft 31 is formed into a convex shape and a tapered portion 33 is provided,
When the rear end portion 34 of the stopper 29 is pressed, the stopper 29
is inclined along the tapered surface of the tapered portion 33, and is provided so that the tip portion 30 is pushed up and escapes from the slit 27.

When the key is turned by 90 degrees, the tapered protrusion 35 protruding from the rear end of the lever 26 comes to press the rear end 34 of the stopper 29, and the receiver is stopped at the tip 30. The coin restraint state is released and the coin is placed in the coin tray 36.
fall inside.

In this state, the door is completely locked and the key can be removed.

To release the locked state, insert the key and turn the key 90 degrees counterclockwise, the locking metal fitting 10 will retract, the pawl 24 will fall into the slit 27', and the locking metal fitting 10 will be in the retracted position. At , the hooking is stopped by the claw 24, and the ruled line 3 returns to its released state.

The coin tray 36 is opened to the outside of the case 4 (on the back side of the door 3) and is provided so that the locker user can easily take out the coins after use.

The coin tray 36 may be replaced with a separate coin storage box (not shown) for guiding coins, and such a structure can also be used as a paid coin locker.

The present invention has an extremely simple structure and has an excellent effect of simplifying the use of lockers for a fee or free of charge.
