Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lock for a coin locker, which can be used as a regular paid coin locker, or as a free coin locker with a coin return type, if necessary.

Below, embodiments of the present invention will be described with reference to the drawings.
is the frame of a locking device for a coin locker, and the entire surface is locked.
A cylinder lock 2 for unlocking operation and a cylinder lock 3 for attaching and detaching the lock device to a coin locker (not shown) are provided, and a coin slot 4 is provided above and a coin return port 5 is provided below.

A locking plate 6 is supported on the inner surface of the frame 1 so as to be movable laterally. Reference numeral 7 designates a driving plate for the locking plate 6, which engages with the rotor part 2a of the cylinder lock 2 with a hole 7a in the middle thereof, rotates together with the rotor part 2a, and engages with a lock #7b at its upper end. By engaging the matching driving pin 8 with the locking hole 6a of the locking plate 6, the rotor B is locked by the key 9.
By rotating the locking plate 2a, the locking plate 6 is protruded laterally from the frame l or retreated to perform locking and unlocking operations.

10 is a locking restrainer, which is rotatably supported by a support bottle 11 passing through a hole 10a, and has coin sensing pieces 10b,
It has a driving pin abutting portion 10c, a driving pin receiving portion 10d, and a coin slot closing piece lOe.

A coin falling path P is formed by two guide plates 12 and 12 on the back side of the coin input slot 4 and the coin return slot 5, and the coin sensing piece 10b is guided through the hole 12a of the inner guide plate 12 into the fin falling path P. I want it inside.

, the lock restraint lO is stably held by a coil spring 13 mounted on the support pin 11 so that its abutting portion 10c faces the drive pin 8 in the unlocked position.

Reference numeral 14 denotes a coin support plate, which is rotatably supported by a support pin 15 passing through a hole 14a, and a coin screwed into a plurality of upper and lower short holes 14b for setting usage fees at corresponding positions according to the set fee. The support pin 14C enters and exits the fin drop portion P through the hole in the guide plate. The coin support plate 14 is urged by a coil spring 16 inserted into the support pin 15 so that the coin support pin 14C is expanded to an outward position so as to be removed from the coin fall path P.

Reference numeral 17 designates a control plate for the coin support plate 14, and its intermediate portion is pivotally connected to the frame by a support pin 18, and an inverted driving piece 17a abuts against the coin support plate 14, and a rotor portion is provided on the other side. A drive pin 19 is provided which engages in the hole a and moves in the axial direction in response to the insertion and removal of the key 9.

Therefore, when the key 9 is inserted, the coin support pin 14
C is in the coin pass laP and supports the coin, key 9
Do not support it when it is pulled out.

Therefore, in the unlocked state, since the key 9 is inserted into the cylinder lock 2, the inserted coin C is supported within the coin passage P by the coin support pin 14c; The coin C is detected by the coin sensing piece 10b.
is pressed outward to rotate the locking restrainer lO and remove its abutting portion 10c from the locus of movement of the drive pin 8, so that the drive plate 7
The locking plate 7 can be moved to the locked position.

In a predetermined usage fee using a plurality of coins, the last coin C inserted causes the coin sensing piece 10b to rotate the locking restrainer 10 and the closing piece 10e to close the coin insertion slot 4. At the time of locking, the drive pin 8 engages with the receiving part 10d to ensure this state.
When the key 9 is pulled out, the control plate 17 and the support pin 18 are moved by the coil spring 16, causing the fin C to fall downward.

At the lowest end of the coin passage P, a passage closing member 20 is provided by a pole 21 so as to be openable and closable, and in normal use, it hangs downward to open the fin passage P, and when used in a coin return type. The passage P is closed by the bolt 22.

In this case, the pin 23 provided at the lower end of the drive plate 7
An opening/closing member 24 driven by the coin return opening 5 is provided at the coin return opening 5, and the opening/closing member 24 uses a shaft 25 as a fulcrum to close the coin return opening 5 when it is locked, and then opens it when it is unlocked. The coins for use are returned to the user when the key 9 is inserted into the cylinder lock 2 to unlock it.

Reference numeral 26 designates a locking plate for the rotor portion 2a of the cylinder lock 2, which is provided so as to be movable up and down by a pin 27 through an elongated hole 26a, and is constantly urged upward by a coil spring 28.

The locking plate 26 has an opening 26b in which the rotor portion 2a is positioned.
The groove 2a+ of the rotor portion 2a is continuous with the opening 26b.
A locking hole portion 26C that engages is provided.

Further, the locking plate 26 is provided with a notch 26d in the middle in the vertical direction, and a stopper 266 that partially closes the notch 26d is provided so as to be openable and closable by a shaft 26f.

The locking plate 26 can be pushed down by rotating the locking piece 3a for attachment to a coin locker (not shown) by operating the cylinder lock 3, and thereby the locking hole 26c is connected to the rotor portion 2a. Since the rotor part 2a can be removed from the groove 2a'+, the rotor part 2a can be pulled out through the opening 26b and replaced.

However, when unlocking, the drive pin 8 is in the notch 126d.
Since the cylinder lock 3 is located at the top of the cylinder and collides with the stopper 268, it cannot be replaced from the outside by operating the cylinder lock 3. However, it is possible because the drive bin 8 moves by +1 when the lock is locked, and in reality it is possible for the user to carry the baggage for a long time. It is necessary to replace the item if it is left in a locked state.

However, if it becomes necessary to replace the cylinder lock when unlocking due to malfunction, etc., operate the cylinder lock 3 in the opposite direction to remove the lock body from the coin locker, and then rotate the stopper 266. The locking plate 26 can be moved from.

As described above, the present invention provides a passage closing member that can be opened and closed at the lower end of the coin dropping passage, a coin return opening is provided at the lower end of the passage, and the chain is opened and closed only when the coin return opening is locked. Since the locker is made up of several members, it can be used as a normal paid coin locker, and if necessary, it can also be used as a free coin locker with a coin return type.
