Description of the Related Art In a conventional free lock device for a coin locker, when a coin is not inserted when unlocked, the latch is prevented from moving in the locking direction. The coin checker is rotated by the weight of the coin that has fallen, and the latch is unlocked, so that the coin can be locked. However, in the conventional locker for a coin locker, the coin insertion slot and the coin return slot remain open at all times in both locking and unlocking. From the coin slot, coin return slot to the inside,
Tools such as a screwdriver or other components are inserted to lock the lock without coins, and when locking, mischief such as removal of coins at the lower part of the coin passage or damage to the internal mechanism of the device is often performed. Was. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the above-mentioned conventional locker for coin lockers,
A coin passage case that forms a coin passage that connects the coin insertion slot and the coin return opening is formed so as to be movable in the left and right direction. When locking after coin insertion, the coin passage case moves to the side, and the front surface is shielded. The coin slot and the coin return slot on the front of the mounting case are simultaneously closed from the inside by the plate, which can prevent mischief in which objects are inserted into the coin slot and the coin return slot, and removal of coins, etc. Accordingly, it is an object of the present invention to provide a locker for a coin locker that can be used for a long time without any trouble. In order to achieve the above object, a lock device for a coin locker according to the present invention is provided with a lock provided with a latch mounted on a base plate, and a lock plate on a top and a bottom of a front plate. A coin passage communicating with the coin insertion slot and the coin return slot is formed, a coin passage case whose rear end is pivotally supported by the substrate and rotates left and right, and locking and unlocking operations are performed.
An interlocking coupling mechanism that transmits the left and right rotation power of the coin passage case via a latch, and a support plate whose base end protrudes from the substrate with the leading end inserted into an opening formed in the middle of the coin passage case. A coin checker that is pivotally supported in the front and rear direction and horizontally rotates in the front-rear direction.The coin passage case is formed with a front plate extending inward to form a coin insertion slot on the front of the mounting case and a shielding plate for a coin return slot. The coin checker has a locking concave portion formed on the inner edge of the distal end portion, and a coin detecting piece inclined from the locking concave portion toward the distal end, and the locking concave portion and the opening edge of the coin passage case opening portion. By urging the spring force in the direction in which the lock is locked, the key inserted into the lock is rotated to rotate the latch in the locking direction, so that the coin passage case interlockingly connected to the latch is rotated. Predetermined Pivoted in the direction, a coin slot of the mounting case by the shielding plate of the front coin passage casing, is characterized by being configured so as to close the coin return slot from the inside. At the time of unlocking, the tip side of the coin checker is rotated inward by the biasing force of the spring, and the locking recess and the opening edge of the opening of the coin passage case are locked, and the coin passage is opened. Since the movement to the outside of the case is prevented, the rotation (movement) of the latch in the locking direction while no coin is inserted is prevented. At this time, the inside of the coin detection piece of the coin checker inserted in the coin passage at right angles is located in the coin passage. [0007] In this state, when a predetermined coin is inserted into the coin insertion slot of each opening facing the mounting case and the front of the device, the coin falls down in the passage and the coin of the coin checker. The coin checker is brought into contact with the detection piece, detects the outer diameter (diameter) of the coin, and rotates the coin checker in a predetermined direction (forward). As a result, the coin checker engagement concave portion is released from engagement with the opening edge of the coin passage case, so that the coin passage case becomes rotatable. Subsequently, when the key is rotated to rotate (move) the latch in the locking direction, the coin passage case interlocked with the latch has its front end centered on its rear end in a predetermined direction (outside). ), The coin insertion slot and the coin return slot on the front face are displaced sideways with respect to the coin insertion slot and the coin return slot on the mounting case, and the coin insertion slot on the front face of the coin passage case is inserted. mouth,
The coin return slot is closed from the inside. Further, the latch is rotated to the locked position, and at the same time, the coin falls to the lower end of the coin passage and is held at a deep portion of the coin return slot. When the key is rotated in the locked state to rotate the latch in the unlocking direction, the latch and the coin passage case are interlocked, and the case is rotated inward, and the opening edge and the coin checker are rotated. The locking concave portion locks, re-locking becomes impossible, the unlocked state is reached, the coin passage case returns to the original position, and the coin insertion slot and the return port are
Since it is opposed to that of the mounting case, the coins at the lower end of the coin passage can be taken out from both coin return openings of the coin passage case and the mounting case.
