Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a wire lock, and more specifically to a wire lock useful as a lock for preventing the loss of a parking violation ticket for a motor vehicle.

(Prior art) In order to prevent the violation sticker from being lost, the wire lock used to attach the violation sticker to the fender mirror, etc., is a wire lock that is used when the key is inserted into the keyhole and turned. When the lock of the hanging cable is released, the free end of the hanging cable is automatically released by being resiliently repelled by a spring inside the lock.

(Problem that the invention aims to solve) However, since the hanging rope is made of wire so that it will not be easily cut, the hanging rope will be unlocked and automatically come off, and at the same time it will elastically change from the U-shape to its original straight shape. There is a problem in that it bounces due to its own elastic recovery force when it tries to return, and hits the body near the fender mirror with force, damaging the painted surface.

The present invention was developed in view of these circumstances. After the wire rope is unlocked with a key, it is automatically locked in a semi-locked state and does not bounce around, making it impossible to use the key. To provide a wire lock that can be removed without any movement.

(Means for Solving the Problems) In order to achieve the object, the present invention includes a spring-like hook in the opening of the introduction hole that is elastically pressed against the locked insertion part in the introduction hole. Once installed, the insertion part is released from the introduction hole and moves out of the introduction hole under the force of a spring, and at the same time the annular groove moves until it reaches the engaging body position, the engaging body engages with the annular groove, resulting in a semi-locked state. It is characterized in that the insertion part is automatically locked to prevent it from coming out, and then the insertion part can be removed from the introduction hole against the elastic force of the hook.

(Function) When the insertion part is inserted into the introduction hole against the spring,
The bolt is biased by a spring and elastically engaged with the annular groove, thereby locking the insertion portion into the introduction hole.

When the lock is released by the rotation of the key inserted into the front keyhole, the lock is released from the annular groove, and the spring's elastic force allows the lock to slide out toward the hole. With respect to the moving insertion part, the engaging body elastically engages with the annular groove to stop the movement of the insertion part and automatically lock the insertion part into a half-locked state, thereby preventing the insertion part from coming out.

The insertion portion temporarily fixed in a semi-locked state within this introduction hole can be pulled out against the elastic force of the hook.

(Example) An example of implementing the present invention will be described in detail below with reference to the drawings.

A in the figure is a wire lock, and this wire lock A
One end 4 of a wire hanging cable 3 is fixed to one end of the lock body 1 with the keyhole 2 in the center of the front in between, and the insertion part 5 of the other end of the hanging cable 3 is inserted to the other side. Hole 6
A guide hole 7 is formed which communicates with the introduction hole 6 in the middle.
The lock body 8 can be freely engaged with the annular groove 9 in the insertion part 5 in the introduction hole 6 by the force of the spring 10, and can be freely removed from the annular groove 9 by following the rotation of the key B inserted into the keyhole 2. A movable body 11 is installed inside the introduction hole 6 so as to be movable by being biased by a spring 12 toward the hole opening 6a, and a spring-like hooking body 13 is installed inside the opening 6a at an insertion portion inside the introduction hole 6. 5 so as to be in elastic pressure contact with it.

The bolt 7 has a tongue piece 14 protruding toward the keyhole 2 side, and the key B rotates when the lock is released with the key B.
comes into contact with the tongue piece 14 so that the bolt 7 can be removed from the annular groove 9 and moved.

Further, the lock body 1 has a combined structure of front and back parts, and the front side part 1a
The connecting protrusion 1c is passed through the back side 1b and caulked on the back side.

The length of the hanging cable 3 is the base C of the fender mirror C ₁
A protective tube 15 made of vinyl, for example, is attached to the surface of the wire to prevent damage to the painted surfaces of the fender mirror C and body D.

It goes without saying that the length of the hanging cable may be changed to a corresponding length if the wire lock A of the present invention is used in other ways, such as for preventing theft of a motorcycle or bicycle.

(Effect of idea) Therefore, the present invention has the following advantages.

Even if you insert the key into the keyhole and turn it to unlock it, the hanging cable will not suddenly jump and will not hit or damage nearby objects. Moreover, the release of the lock can be confirmed visually and by the shock when the insertion part moves slightly and is temporarily secured, and subsequent removal is smooth.

Since the insertion portion is temporarily held in a semi-locked state by a spring-like hook, the shock when automatically locked is soft and good.

Claims (1)

[Scope of utility model registration request] One end 4 of a wire hanging cable 3 is fixed to one end of the lock body 1 with the keyhole 2 in the center of the front in between, and the insertion part 5 of the other end of the hanging cable 3 is inserted to the other side. A hole 6 is drilled, and a bolt 8 is inserted into the guide hole 7 which is in communication with the middle of the introduction hole 6, so that it can be freely engaged with the annular groove 9 in the insertion part 5 in the introduction hole 6 by being biased by a spring 10.
A movable body 11 is installed inside the introduction hole 6 so that it can be moved freely by being biased by a spring 12 toward the hole opening 6a. At the same time, the wire lock has a spring-like hook 13 installed in the hole 6a so as to be elastically pressed against the insertion part 5 in the introduction hole 6.
