A locking recess 45 provided on the locking plate 43 is fitted onto a locking convex portion 44 provided on the locking plate 43, so that the locking lever member 36 and the locking plate 40 are integrated against rotation, and the sliding A transmission plate 46 for transmitting the operation of the member 14 is rotatably provided at a position close to the lever 15, and has one side edge in contact with the lever 15 and the other side edge in the insertion hole 37 laterally. The pin 47 comes into contact with the outer tip of a pin 47 that is provided so as to be freely retractable, thereby transmitting the operation of the lever 15 to the pin 47. In this state, that is, in a state in which the inner end of the pin 47 protrudes into the insertion hole 37, the groove 48 in which the pin 47 can engage is inserted into the insertion hole 47 of the locking lever member 36, and the lock lever member 36 is in a locked state. In case,
A lock is provided on the cover E at a portion corresponding to the pin 47 in a direction perpendicular to the rotation direction, and is provided on the cover E at an end opposite to the locking portion 49 of the locking plate 40 and the rotation axis. A leaf spring locking portion 50 is provided in relation to the leaf spring locking portion 34, and both leaf spring locking portions 34,

It is configured to be held in an unlocked state and a locked state. Although not shown in the drawings, it is also possible to attach the cover for the entire lock from behind the cover E.

Therefore, in the case of normal locking, all the recesses 13 formed in the cam 12 of the gearbox B are in a state where they can mesh with the slide member 14, and the slide member 14 is in contact with the lever 15. The pin 47 is pushed through the plate 46 in the direction of engagement by a spring bias in the direction in which the pin 47 protrudes. Since the pin 47 does not protrude, the locking lever member 36 is rotatable, and as the locking lever member 36 rotates, the locking plate 40 rotates and protrudes laterally, as shown in FIG. In this state, the control hole 25 of the control plate D and the protrusion 16 of the push button 11 are in the same position as shown in FIG. The unlock number can be changed from the unlock number, and when the push button 11 is pressed, the cam 12 rotates a unit in conjunction with the number wheel 10, and the protrusion of the slide member 14 that has been engaged with the recess 13 is rotated. The lever 15 is pushed out and slid, that is, the lever 15 is slid, and the movement is transmitted to the pin 47 by the transmission plate 46, and the pin 47 is displaced inward of the locking lever F, and its innermost end is connected to the locking lever. The locking lever member 36 is engaged with the groove 48 of the member 36 to restrict rotation of the locking lever member 36, and the locker door can be locked by performing the above operation with the locker door closed (not shown). To unlock the lock, press the push button 11 and match the number on the number wheel 10 to the unlocking number so that the recess 13 of the cam 12 can engage with the slide member 14, then the pin 47 The slide member 14 automatically slides due to the spring bias, the pin 47 projects outward, and the rotation restriction of the locking lever member 36 is released.The locking lever member 36 is rotated and the locking plate 40 can be stored on the side of the locker lock as shown in the imaginary line in Figure 3 and unlocked. In this state, the locking part 49 of the locking plate 40 comes into contact with the protrusion 26 of the control plate D, and slides the control plate D in the lateral direction, changing the position of the control hole 25 of the control plate D. The protrusion 16 of the push button 11 is deviated from the position, restricting the operation of the push button 11 and making it impossible to change the number.

Additionally, the unlock number can be reset easily as follows. That is, after opening the locker door as described above, in that state, the locking lever member 36 is rotated again to the locked state, the contact with the protruding piece 26 is released, and the control plate D is moved by the spring 33. The position of the protrusion 16 of the push button 11 and the position of the control hole 25 of the control plate D are automatically slid to match, the lever 15 at the rear is fixed, and the slide member 14 meshes with the recess 13 of the cam 12. When the push button 11 is pressed while the rotation of the cam 12 is regulated, the number wheel 10 rotates by a unit, but the cam 12 does not rotate and the number of the number ring 10 changes. The position of the recess 13 of the cam 12 can be shifted, and the unlock number can be reset. When the lever 15 is unlocked, the locking and closing operations described above become possible with the same operation.

F. Effects of the invention According to the Locker lock of the invention, when the lock is unlocked, the lock plate comes into contact with the protrusion of the control plate and slides the control plate to restrict the push button operation. No more changing numbers by mistake
In addition, since the pin is engaged with the groove of the locking lever member when the lock is locked, the rotation of the locking lever member can be reliably regulated, which not only provides an excellent crime prevention effect, but also allows you to carry the key at all times. Even if you do not have a locker, you can easily lock and unlock the locker door by simply pressing the push button on the front panel of the key and matching the number with the preset unlock number. In addition, the locking and unlocking conditions can be reset by pressing the lever protruding from the back of the lock with your finger to lock the slide member and the recess of the cam in an engaged state, and pressing the push button to rotate only the number wheel. This can be easily done by simply changing the positional relationship between the number of the number wheel and the recess of the cam, and its structure can be easily assembled by simply fitting each part.
In addition, it is possible to manufacture a large number of the same product and set different unlocking conditions for each product.
