2. Description of the Related Art Conventionally, a wire lock has been used to prevent a motorcycle from being stolen. This is, for example,
It is disclosed in Japanese Patent Application Laid-Open No. 11259/1986 and Japanese Utility Model Application Laid-Open No. 61-173672. In the wire lock described in Japanese Utility Model Application Laid-Open No. 59-111259, a take-up reel is housed in a case, and a wire having a locking portion at the tip is rewindably wound around the take-up reel. Is provided with a locked portion which can be locked with the pulled-out locking portion, and a lock such as a cylinder lock is provided on the locked portion.

A wire lock described in Japanese Utility Model Application Laid-Open No. Sho 61-173671 is disclosed in Japanese Utility Model Application Laid-Open No. Sho 59-111259.
The main difference is that the outer edge of the winding collar is projected out of the case, and the outer edge of the collar is rotated to take up the winding reel. The point is that it can be rotated.

[0004] In order to use such a wire lock to prevent theft of a motorcycle, first, the wire is pulled out of the case by pinching the end of the wire, and the wire is formed into a loop. The connection is made, or the vehicle body and the wheel are connected, and then the locking portion at the tip of the wire is locked with the locked portion of the case. Then, the lock provided on the locked portion is locked so that the lock is not unjustly removed.

[0005] In any of the above publications, when the wire lock is not used, the wire can be wound and stored on a take-up reel in a case, so that the wire is simply wound like a coil. The elasticity does not cause the ring to expand, the wire is easily stored, and it is relatively easy to handle.

[0006]

However, Japanese Utility Model Application Laid-Open No. 59-111259 and Japanese Utility Model Application Laid-Open No.
In the wire lock described in JP-A-6771, the locked portion for locking the locking portion at the distal end of the wire is arranged so as to protrude from the peripheral edge of the case. There is a drawback that the above-mentioned protruding portion becomes an obstacle when the lock is held in a hand.

[0007] The present invention has been made to solve the above problems. That is, an object of the present invention is to provide a wire lock which is compact and easy to carry and handle when the wire is housed, and the case hardly protrudes from the case.

[0008]

Means for Solving the Problems The present invention is wound in a casing

It is closed by. The outer peripheral edge of the plate 21 is fitted and fixed at a bent portion on the outer periphery of the case 2, and the side surface of the take-up reel 3 is supported by the plate 21. Also,
The back cover 22 has an outer peripheral edge fitted at a bent portion provided on an inner periphery of the circular hole of the plate 21 and supports all the storage components inside the take-up reel 3 described below. It has become.

As shown in FIG. 3, a cavity is formed inside the take-up reel 3, and a rod-shaped slider 51 is provided substantially at the center of the take-up reel 3 in a direction perpendicular to the axial direction of the locking hole 31. It has been incorporated. This slider 51 is formed so that its tip end side (the side of the locking hole 31) is slightly thinner.
A step portion 51b is provided between the base portion 51d and the opposite side portion 51d (see FIG. 4). Also, the tip of the slider 51
The entrance side of the locking hole 31 is cut obliquely to form a claw 51a, and a compression coil spring 52 is incorporated into the base 51d between the base 51d and the wall surface of the cavity of the take-up reel 3.

The other side (the right side in FIG. 3) of the wire lock of the slider 51 is supported by the base member 6 and is capable of reciprocating in a direction perpendicular to the locking hole 31. Also, as shown in FIG.
a, the step 51b collides with the hollow wall surface of the take-up reel 3 and the locking hole 3
It cannot move in the direction of 1. The other side surface of the base member 6 is supported by the back cover 22.

Next to the slider 51, as shown in FIG.
A cam 53 is incorporated. This cam 53 has a notch 53a cut at a right angle on the outer periphery of a thick disk, and a slightly large diameter concentric protrusion 53b on another part of the outer periphery of the disk. Things. When the step 51b of the slider 51 collides with the wall surface of the cavity of the take-up reel 3, the notch 53a is moved to another step 5 of the slider 51.
1c, and at the same time, the left side surface of the protruding portion 53b in FIG. 4 just comes into contact with the opposing wall surface of the cavity of the take-up reel 3.

On one side (left side in FIG. 3) of the cam 53, there is provided a cylindrical cylinder portion 54 formed integrally with the cam 53. The cylinder part 54 is rotatably incorporated in the cavity of the take-up reel 3, and a lock 7 having a keyhole 71 on the surface is further mounted on the outside thereof. The locking hole 31, the slider 51, the compression coil spring 52, the cam 53, the cylinder 54, and the lock 7
The locked portion 5 of the wire lock according to the present embodiment is configured.

According to the wire lock of the present embodiment configured as described above, when using the wire lock to prevent the motorcycle from being stolen, first, hold the case 2 in one hand and hold the case 2 with the other hand. Locking portion 4 of wire 4 exposed outside
Grab 1 and pull. Thereby, the take-up reel 3 is rotated, and the wound wire 4 is unwound and comes out.

Then, the pulled wire 4 is, for example,
As shown in FIG. 5, the wheel 8 of the motorcycle C and the pole 9 on the road are passed together so as to surround them, or the pipe and wheel of the vehicle body are passed together so as to surround them (not shown). Are connected by a loop of wire 4,
In this state, the locking portion 41 at the tip of the wire 4 is inserted into the locking hole 31 of the take-up reel 3. Then, the locking portion 41 is pushed inward, and the locking portion 41 pushes back the claw portion 51 a of the slider 51 against the elastic force of the compression coil spring 52 so that the locking portion 41 reaches the bottom of the locking hole 31. . Then, the claw portion 51a projects again as shown in FIG. 3 by the elastic force of the compression coil spring 52, the locking portion 41 is automatically locked to the claw portion 51a, and the wire 4 forms a loop.

As described above, the locking between the locking portion 41 and the claw portion 51a is performed by the compression coil spring 52 inside the wire lock 1.
Since it is held by the elastic force of the above, there is no possibility of being released illegally. Therefore, there is no possibility that the loop of the wire lock 1 will be unraveled, and the motorcycle C shown in FIG. 5 cannot move, thereby preventing theft.

In order to move the motorcycle C by releasing the locking between the locked portion 41 and the locked portion 5 locked as described above, insert a key suitable for the lock 7 into the keyhole 71, Twist counterclockwise. Then, the cylinder portion 54, that is, the cam 5
3 rotates counterclockwise, the notch 53a of the cam 53 comes into contact with and pushes the step 51c of the slider 51, and the slider 51 moves backward in the unlocking direction against the elastic force of the compression coil spring 52. Then, the claw portion 51 a at the tip of the slider 51 is retracted from the locking hole 31. As a result, the locking between the locking portion 41 of the wire 4 and the claw portion 51 a is released, and the locking portion 41 of the wire 4 is separated from the locking hole 31 of the locked portion 5.

When the counterclockwise hand force applied to the key is released, the slider 51 advances by the elastic force of the compression coil spring 52 until the stepped portion 51b collides with the hollow wall surface of the take-up reel 3. , Automatically return to the original position. Similarly, in the direction of the keyhole 71, when the counterclockwise hand force applied to the key is released, the step portion 51c of the slider 51 comes into contact with the notch portion 53a of the cam 53, and the cam is held until the slider 51 stops. In order to rotate 53 clockwise, the keyhole 71 is automatically
Return to the original direction. If the key is further rotated clockwise, the side surface (left side in FIG. 4) of the projection 53b of the cam 53 collides with the opposing wall surface of the cavity of the take-up reel 3, so that it cannot be further rotated.

When the wire 4 is separated from the locking hole 31, the take-up reel 3 is rotated clockwise using the lever 32 of the raised portion 34, and the wire 4 protruding from the case 2 is taken out of the take-up reel 3. And wound up in the case 2 as shown in FIG.

As is apparent from the above description, in the wire lock of the present embodiment, the locked portion 5 for locking the locking portion 41 of the wire 4 is provided on the shaft center of the take-up reel 3. So
The outer shape of the case 2 was substantially circular, and a portion that largely protruded outside when the wire 4 was stored could be eliminated. Therefore, the wire lock can have a compact and beautiful design, and when the wire 4 is stored,
It became very easy to carry and handle.

The present invention is not limited to the above-described embodiment. For example, the above-mentioned locked portion is not provided on the take-up reel, but is arranged at a position which becomes the axis of the take-up reel. It may be provided on a fixed member, and a cylindrical take-up reel may be rotatably mounted on the outer peripheral side of the fixed member. Further, the locked portion may use a spring to move the slider without using a spring, thereby locking the wire locking portion to the locked portion. Also, instead of pushing the locking portion of the wire into the locking hole to lock the locked portion, the locking portion is inserted into the locking hole, and then the locking portion is rotated slightly to lock the locked portion. May be locked. Also,
The fixing of the plate and the case or the fixing of the back cover and the plate may be performed by screwing or the like.
