[Prior art]

 BACKGROUND ART So-called wire locks using wires have been widely known, and are widely used as lock devices for bicycles. This wire lock is composed of a lock main body a having a lock mechanism as shown in FIG. 4, and a wire b whose one end is locked to the lock main body a. When used as a lock device for a bicycle, for example, the tip of the wire b is passed between the spokes of the bicycle wheel, and then the lock body engaging portion b1 provided at the tip of the wire b is inserted into the lock body a. The wheel is locked by being fitted and inserted into the wire fitting hole a1 provided at the wheel.

[0003]

[Problems to be solved by the device]

 However, in this case, since the wire b is considerably long, it becomes bulky as a whole. As a result, for example, when using it on a bicycle, it is necessary to carry it when going out, but it is difficult to store it in a bag etc., on the other hand, if it is caught on the handle of the bicycle, etc. There is a problem that there is a danger of being caught in something and it is dangerous. It also becomes inconvenient when it is stored.

The present invention has been proposed in view of the above circumstances, and an object thereof is to keep the wire length short and to be compact as a whole at a normal time. It is to provide a coil wire for a wire lock that can be extended and used.

[0005]

Means for Solving the Problems The present invention solves the above-mentioned problems by providing a coil wire for a wire lock having the following features. The coil wire for wire lock of the present invention comprises a stretchable portion. The stretchable portion is composed of a plurality of ring-shaped portions arranged side by side in the lateral direction. These ring-shaped parts have a diameter smaller than the distance between two adjacent spokes of the wheel of a motorcycle such as a bicycle or a motorcycle, and the stretched part is coiled by sequentially winding the wire multiple times. Formed to have a shape. Then, as the elastic part receives a force from the outside, the length of the elastic part expands due to the deformation of the annular part, and as the force is removed, the elastic part of the annular part expands and contracts. It was designed to return to its original state. Further, as described in claim 2, the wire is provided with a wire operating portion of a predetermined length extending from the expandable portion on the tip side. And this wire operation part is equipped with the lock main body engagement part at the tip. Further, the above-described problem is solved by providing a coil wire for a wire lock in which the lock main body engaging portion is arranged so as to project radially outward of the ring-shaped portion in the expandable portion.

[0006]

[Action]

 In the present invention, since the wire is provided with the coil-shaped expansion / contraction part, the expansion / contraction part is coiled in a normal state where no external force such as pulling is applied, and the total length of the wire is short. Becomes This makes the whole compact. On the other hand, for example, when locking and locking the wheels of a bicycle, pulling the tip side of the wire can deform the ring-shaped part of the expandable part and extend the length of the expandable part. Can be stretched. As a result, it can be used with the same length as the conventional one. Further, at that time, since the diameter of the ring-shaped portion is smaller than the distance between the adjacent spokes of the two-wheeled vehicle, it is possible to easily pass the telescopic portion when passing between the spokes. The spokes can be easily removed without disturbing the spokes. Further, as described in claim 2, a wire operating portion extending from the expanding / contracting portion is provided, and the distal end portion of the wire operating portion is arranged so as to project radially outward of the annular portion of the expanding / contracting portion. By providing the lock main body engaging portion, the operation of inserting the lock main body engaging portion of the wire into the wire insertion hole of the lock main body can be facilitated.

【Example】

 An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a front view of an embodiment of the coil wire for wire lock of the present invention, and FIG. 2 is a front view of the wire attached to the lock body.

The wire 1 of the present invention is used as a wire for a so-called wire lock, one end of which is attached to a lock body having a lock mechanism.

The wire 1 in this embodiment is composed of a single wire whose outer circumference is covered with a covering member made of a synthetic resin such as vinyl over its entire length, and has a lock body mounting portion 2 and a wire operating portion 3. , And the elastic portion 4.

The lock body mounting portion 2 is formed in a substantially linear shape and is arranged on the rear end side of the wire 1. In this embodiment, it is formed over a range of about 10 cm from the rear end. Further, a mounting metal fitting 21 having a locking groove 22 is mounted on the rear end of the lock body mounting portion 2, and the mounting metal fitting 21 is arranged at a position projecting downward from the expansion / contraction portion 4. The wire 1 and the lock main body 5 are attached by attaching the mounting bracket 21 to the lock main body 5. Specifically, as shown in FIG. 2, it is attached by being fixed to a wire attaching portion 51 provided on the lock body 5. Then, at this time, since the lock body engaging portion 21 and the wire attaching portion 51 of the lock body 5 are easily attached, since they are formed in a substantially linear shape. The mounting bracket 21 is provided for convenience of mounting, and may not be necessarily provided, and the wire 1 may be directly mounted.

The wire operating portion 3 is disposed on the distal end side of the wire 1, is formed in a substantially linear shape over a range of about 10 cm from the distal end like the lock body mounting portion 2, and has a metal tip at its front end. It is provided with a lock body engaging portion 31 made of a product. The lock body engaging portion 31 is arranged at a position projecting downward from the expansion / contraction portion 4. Therefore, in this embodiment, the lock body mounting portion 2 and the wire operating portion 3 are symmetrical with respect to the expansion / contraction portion 4, and both of them form the lock body mounting portion 2 or the wire operating portion 3. ing.

The lock main body engaging portion 31 is for locking / unlocking the lock main body 5 as appropriate, has a locking groove 32, and as shown in FIG. When the portion 31 is inserted into the wire insertion hole 52 provided in the lock body 5, the portion 31 is locked to the locking piece 53 arranged in the lock body 5, and is locked in that state. On the other hand, unlocking is performed by unlocking the key 6 to disengage the locking piece 53 of the lock body 5 from the locking groove 32 of the lock body engaging portion 31.

The lengths of the lock body attaching portion 2 and the wire operating portion 3 are not limited to the above-mentioned lengths and can be changed as appropriate.

The elastic part 4 is arranged between the lock body mounting part 2 and the wire operating part 3 and is composed of a plurality of ring-shaped parts 41 ... 41 arranged in parallel in the left-right direction. These ring-shaped portions 41 ... 41 are formed in the same shape in order from the lock body mounting portion 2 side to the wire operating portion 3 side, and are formed into a coil shape by winding a plurality of times. Further, the diameter of these ring-shaped portions 41 is such that it can pass between two adjacent spokes 7, 7 of a plurality of spokes arranged on a wheel 8 of a bicycle or a motorcycle as shown in FIG. It is made in the size of. The ring-shaped portion 41 is not limited to one in which all the rings have the same size, but can be changed as appropriate. Also, in this embodiment, the ring-shaped ring-shaped portions 41 ... 41 are brought into close contact with each other, and the expansion / contraction portion 4 as a whole is formed into a so-called close-wound coil shape. It may be formed in a so-called coarsely wound coil shape having a slight gap between them.

Therefore, when the elastic portion 4 is pulled from, for example, the lock body mounting portion 2 side or the wire operation portion 3 side, the shape of the ring-shaped portion 41 of the elastic portion 4 is deformed, so that the length of the elastic portion 4 increases. Is stretched, and when pulling is stopped, the stretchable portion 4 stretched by the elastic force of the ring-shaped portion 41 contracts and returns to its original state.

Next, the function of the wire lock to which the wire 1 of the present invention is attached will be described by taking a case where it is used for a bicycle as an example. First, as shown in FIG. 3, when the bicycle wheel 8 is locked, the wire 1 is passed from the wire operating portion 3 side between the spokes 7 of the wheel 8 as in the conventional wire lock. At that time, the elastic portion 4 is freely stretched by pulling the wire operating portion 3, so that the wire 1 can be made to have the same length as the conventional one, and the length can be made sufficient to wind and stop the wheel. Can be used. Moreover, since the diameter of the ring-shaped portion 41 in the stretchable portion 4 is made smaller than the distance between the spokes, it is possible to easily pass between the spokes.

After that, by pushing the lock body engaging portion 31 of the wire operating portion 3 passing through the spokes 7 into the wire fitting insertion hole 52 of the lock body 5, the lock mechanism of the lock body 5 is used as described above. The wheel 8 can be locked, but when the lock body engaging portion 31 is pushed in, the wire operating portion 3 is formed in a substantially linear shape, and the lock body engaging portion 31 extends from the expanding / contracting portion 4 to its annular portion 41. Since it is arranged at a position projecting outward in the radial direction, the push-in operation can be easily performed.

On the other hand, when unlocking the wheel 8 of the bicycle, the lock body engaging portion 31 of the wire operating portion 3 is disengaged from the wire fitting hole 52 by operating the key 6 of the lock body 5, and the spokes 7, 7 This can be done by pulling out the wire 1 that has passed through the gap, but even at that time, since the diameter of the ring-shaped portion 41 is smaller than the distance between the spokes 7, 7, it is easy to do without the spokes getting in the way. The gap between the spokes can be removed.

Then, the lock main body engaging portion 31 of the wire operating portion 3 is pushed into the wire fitting insertion hole 52 of the lock main body 5 to bring it into the locked state, whereby the whole wire lock can be made small and compact. Therefore, when riding a bicycle thereafter, it can be conveniently stored in a bag or the like and carried.

The lock body 5 to which the wire 1 is attached in the present invention can be adapted to various conventionally used ones, and can be appropriately modified and used. Further, in the present embodiment, the lock body attaching portion 2 and the wire operating portion 3 are formed in a linear shape, but the present invention is not limited to this aspect, and the lock body engaging portion 31 of the lock body attaching portion 2 is a telescopic portion. It suffices that it is formed so as to project sufficiently outward in the radial direction from 4, and it may be formed by being curved. Further, the mounting metal fitting 21 of the lock main body mounting portion 2 and the lock main body engaging portion 31 of the wire operating portion 3 are not limited to those described in this embodiment, and for example, the mounting metal fitting 21 and the lock main body engaging portion. Instead of providing 31, both ends of the wire 1 may be bent to form a ring shape and connected to a lock main body provided with a bar, which can be appropriately modified and used.

[Effect of device]

 As described above in the embodiments, the present invention makes the total length of the wire short in a normal time due to the coil-shaped expansion / contraction portion, and thus the entire wire lock can be made compact. On the other hand, when locking the wheel of a bicycle, for example, the wire operation part can be pulled to deform the stretchable part and extend the length of the stretchable part, which can extend the entire length of the wire. Can be used in length. However, at that time, since the diameter of the ring-shaped portion is smaller than the distance between the adjacent spokes on the wheel, the elastic portion can be easily passed and removed when passing between the spokes. The spokes can be easily removed without disturbing the spokes. Further, a wire operating portion extending from the telescopic portion is provided as in claim 2, and the lock body engaging portion at the tip end of the wire operating portion is projected outward in the radial direction of the annular portion of the telescopic portion. By arranging in this manner, the operation of fitting the lock body engaging portion into the wire fitting hole of the lock body can be facilitated and can be conveniently used.
