Description

[Detailed description of the invention] The present invention relates to a new style of lock.

Conventional locks have a mechanism in which the key is rotated around an axis in the insertion direction to open and close the lock, and a mechanism in which the key is slid in the insertion direction to open and close the lock. There are several types of locks, and all of the locks that do exist are constructed in one of the styles described above.

The present invention is characterized in that the lock can be opened and closed by swinging the key inserted into the key insertion hole, and it is an object of the present invention to provide a new type of lock.

A preferred embodiment of the present invention will be described below with reference to the drawings. A lock body 1 has a keyhole 5 on the front side and communicates with a space a on the back side closed with a lid 6. A pivot part 7 is provided on the back side of the keyhole 5, and the actuating body 2 is mounted so as to be swingable at a fixed angle from the closed position to the open position using the pivot part 7 as a fulcrum, and the actuator 2 can be pivoted at a fixed angle from the closed position to the open position. The pin hole 8 of the pin tumbler 4 is located on the sliding surface a- of the operating body 2.
The bottle hole 9 formed along the key insertion hole 3 of the operating body 2...
A group of pin tumblers 4, that is, a spring 4-a and a driver 4-b are opened in each of these holes 8 and 9, facing each other.
Insert A and pin 4-c, and with key A inserted, use key thread A-1 to connect screwdriver 4-b and pin 4.
- The contact end surface with c is flush with the sliding surface a-, and the actuating body 2 is formed so that it can swing together with the key A inside the space a.

In addition, window holes 10 are opened in the six lids facing the closed position after the actuating body 2 swings, and the actuating rod 11- of the locking part 11 is inserted into the window holes 10.
a, and place the actuating rod 11-a on the swing locus of the operating part A-2 that is connected to the key A, which swings together with the actuating body 2, and then move the actuating rod 11-a by the operating part A-2. 11-a is formed to open or close the lock.

The actuating body 2 is provided with a pivot portion 12 at the front end, and this pivot portion 1
2 is pivotally attached to the pivot point of the lock body 1, and is formed to be able to swing freely about the pivot point as a fulcrum, and a spring 13 is inserted between the rear surface of the actuating body and the surface a inside the opposing space. The actuating body 2 is installed in a predetermined relationship in such a manner that the generated force is strong while it is in the middle of swinging, and becomes weaker at its front and back positions, so that it is temporarily locked at the front and back of the swing, that is, at the opening/closing side device.

Further, the actuating body 2 has a key insertion hole 3 communicating with the keyhole 5 extending from the pivot portion 12 at the front side end to the back side end.On the other hand, even in the open position after swinging, the actuating body 2 is connected to the actuating rod 11-a. without touching it,
The operating part A-2 of the key A inserted into the key insertion hole 3 has a concave notch 14
The operating rod 11-a is exposed at the top and set in a relationship where it can perform unlocking or closing operations.

Furthermore, although not shown in the drawings, it is also possible to enable the operating member 2 to directly unlock or close the operating rod 11-a without providing the concave cutout surface 14; in this case, Operation part A of key A
-2's function is performed by the operating body 2.

The locking part 11 is a mechanism for opening or closing a lock piece, a lock rod, a switch, etc., depending on its use, and has an operating rod 11-a for setting it in the unlocked or closed state. As the actuating body 2 swings, the operating part A-2 or the actuating body 2 is operated in response.

In the drawing, the actuating rod 11-a is set to be in the locked state in the closed position before the actuating body 2 swings, and to be in the unlocked state in the open position after swinging, but the present invention is not limited to this. You are also free to set the operations in the opposite relationship.

Further, the locking portion 11 may optionally be provided integrally with the operating body 2 as shown in FIG.

The key A has a key thread A-1 on one side edge that can operate the pin tumbler 4, that is, the driver 4-b and the pin 4-c on the same level as the sliding surface a, and the female side edge has a key thread A-1. An operating portion A-2 of the rod 11-a is formed so that the operating rod 11-a can be opened and closed.

Therefore, according to the present invention, when inserting the key A from the keyhole 5 into the key insertion hole 3, the pin tumbler 4 is level matched and the first
When the first key A is swung, the operating body 2 swings about the pivot portion 12 at one end, guiding the operating portion A-2 to the operating rod 11-a position, and the operating rod 11-a is not operated. When the key A is pushed by the part A-2 to open the lock, when the key A moves back together with the operating body 2, it returns to its original state and closes the lock.

In the above embodiment, it is optional to use the pin tumbler 4 as a desk tumbler, and this does not change the spirit of the present invention in any way.

As described above, the present invention provides a lock body having a keyhole on the front side and a pivoting part on the back side of the keyhole in a space communicating with the keyhole, which can be pivoted to the pivoting part on the front end. The actuating body is provided with a pivot part and has a key insertion hole penetratingly formed from the pivot part to the rear side end, and the pivot part is pivotally attached to the pivot part, thereby sliding the inside of the space using the pivot part as a fulcrum. It is mounted so that it can swing freely from the closed position to the open position 1 along the surface, and a pin hole leading to the key insertion hole is drilled between the operating body that moves to the closed position and the sliding surface facing it. The pin hole is equipped with a part of the pin tumbler that corresponds to the key thread of the key and is level with the sliding surface, and the key is inserted through the key hole into the key insertion hole, and the key is integrated with the operating body and the pivot part is the fulcrum. Since the lock is opened and closed by swinging, the lock can be opened or closed by inserting the key into the key insertion hole and swinging it.

As a result, the lock can be mounted on the back or upper and lower surfaces where it is difficult to turn or push the key, but can be opened and closed smoothly by swinging the lock.

Therefore, the intended purpose was achieved.
