Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a wire lock used for attaching to a wheel of a motorcycle as a detent and for connecting an article such as a motorcycle to some structure or the like.

[0002]

[Prior art]

 Conventionally, a wire lock used to prevent theft of motorcycles and the like is known. This type of wire lock is provided with a wire rope that can be flexibly bent and a locking mechanism that is provided at both ends of the wire rope and that can be engaged with and disengaged from each other. As a result, it was possible to mount it on a wheel of a motorcycle as a detent or to connect an article such as a motorcycle to some structure or the like.

[0003]

[Problems to be solved by the device]

 However, in the conventional wire lock, the wire rope was elastically deformed into a loop shape, and when the locking mechanism was disengaged, the bent wire rope suddenly stretched and the wire lock was unexpectedly locked. It was easy to hit the end of. As a result, the wire lock may be damaged or soiled, and the object to which the wire lock is hit may be scratched.

In this respect, if a chain lock uses a chain instead of a wire rope, it does not bend even if the chain is looped, but the chain has almost no tension, and if it has a midway part, it will end. Since the part hangs down and it is not possible to maintain the desired shape, for example, when inserting it in the gap of the spokes of a motorcycle, you have to hold the end and insert it, compared to a wire lock. There was a problem that it took time.

[0005] Therefore, an object of the present invention is to provide a wire lock that can be deformed relatively freely and can maintain its shape, and which can be easily attached or detached.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides, as claimed in claim 1, a wire rope which can be flexibly bent, and a locking mechanism which is provided at both ends of the wire rope and is engageable with and disengageable from each other. The wire rope has a wire shape that becomes a loop shape by the engagement of the locking mechanism, and the wire rope has a structure capable of maintaining the shape in a deformed state.

Further, the wire lock according to claim 2 is characterized in that at least a part of the wire rope is made of a mild steel wire rod. Further, the wire lock according to claim 3 is characterized in that the portion not exposed on the outer peripheral surface of the wire rope is made of a mild steel wire rod.

Further, the wire lock according to claim 4 is characterized in that the core wire of the wire rope is made of a mild steel wire material.

[0009]

[Embodiment of device]

 According to the wire lock of the first aspect, the wire rope has a structure capable of maintaining the shape of the wire rope in a deformed state. Therefore, when locking, it is possible to deform the wire rope into a desired shape in advance and easily attach any part of the wire lock by hand. , Even if the locking mechanism is disengaged, the shape of the wire rope is maintained, so the end of the wire lock does not hit the unexpected object.

Here, various concrete structures of the wire rope capable of maintaining the shape can be considered. For example, a typical wire rope has a structure in which several hard steel wire rods are twisted together, or a set of several hard steel wire rods twisted together. It has a strong spring property, which causes elastic deformation of the wire rope. Therefore, if a part or all of this hard steel wire is replaced with a wire whose shape is not elastically restored and is not deformed by its own weight, a desired wire rope that is not elastically deformed can be obtained. Specific examples of the wire rod which can maintain the deformation in this way include a mild steel wire rod and a synthetic resin wire rod.

Particularly, when at least a part of the wire rope is made of a mild steel wire rod as described in claim 2, the wire rope can be freely bent into an arbitrary shape like a wire, and the strength can be increased. It is possible to obtain a sufficiently satisfactory product. When forming a part of the wire rope with a mild steel wire, it is preferable that the portion not exposed to the outer peripheral surface of the wire rope is formed with a mild steel wire, as described in claim 3. That is, the exposed portion on the outer peripheral surface of the wire rope is made of hard steel wire, as in the conventional wire rope, and the mild steel wire is not exposed on the surface. By doing this, only the elastically deformable hard steel wire is exposed on the outer surface, so unlike ordinary wires, there is no visible irrecoverable strain on the surface. . In addition, the surface strength of the wire rope is ensured to be equivalent to that of a wire rope made only of hard steel wire, and the mild steel wire is not directly damaged even if it comes into contact with external materials.

Further, in order to configure the portion not exposed on the outer peripheral surface of the wire rope in this way by the mild steel wire rod, it is preferable that the core wire of the wire rope is configured by the mild steel wire rod. That is, there are some common wire ropes that consist of only a few stranded wires, and some that consist of a few stranded wires and a single core wire that is arranged at the center of the shaft. However, in the wire lock according to the fourth aspect, the wire rope has the latter structure, and the core wire thereof is made of the mild steel wire material. This makes it possible to obtain a desired wire rope in which the mild steel wire rod is not exposed on the outer peripheral surface of the wire rope and is not elastically deformed.

In addition to the structure described in claim 4, for example, in the case where the wire rope has a structure in which several sets of hard steel wire rods twisted together are further twisted If the core wire of each set is made of mild steel wire rod, by twisting several sets of these wires, it is possible to make a wire rope without the core wire of the shaft center. As a result, a desired wire rope that is not elastically deformed can be obtained.

As for the structure of the locking mechanism, any known locking mechanism used in this type of wire lock can be adopted. Specifically, for example, it can be locked / unlocked when a specific number set is lined up by turning several rings arranged on the outer circumference of the cylinder, or a cylinder lock is operated by using a key. It does not matter whether it can be locked or unlocked.

[Specific Example] Next, in order to further clarify the embodiment of the present invention, a specific example of a wire lock to which the present invention is applied will be described with reference to the drawings. The specific examples described below are merely examples of the embodiments of the present invention, and the embodiments of the present invention are not limited to the specific examples illustrated below.

As shown in FIG. 1, a wire lock 1 as a specific example includes a wire rope 2 which is long and can be bent flexibly, a female locking member 3 provided at one end of the wire rope 2, and a wire rope 2. It is composed of a male locking member 4 provided at the other end and a vinyl tube 5 that covers the outer circumference of the wire rope 2, and the female locking member 3 and the male locking member 4 can engage and disengage with each other. It constitutes the locking mechanism. The female locking member 3 and the male locking member 4 are well-known members that can be engaged and disengaged by rotating a ring arranged on the outer periphery of the female locking member 3 to align the three numbers in a specific combination.

As shown in FIG. 2 (a), the wire rope 2 of the above structure is composed of one soft steel wire rod 7 serving as a core wire and six hard steel wire rods 8 serving as stranded wires. There is. The hard steel wire rod 8 is twisted around the mild steel wire rod 7 so as to draw a spiral on the outer circumference, and completely covers the outer circumference of the mild steel wire rod 7.

In the wire rope 2 configured in this manner, the hard steel wire rod 8 is elastically deformed, but the mild steel wire rod 7 is plastically deformed, so that the spring property is lost as a whole, and the wire rope 2 is Similarly, the shape can be maintained in a state of being deformed into an arbitrary shape. Therefore, when locking, the wire rope 2 is deformed into a desired shape in advance, so that any part of the wire lock 1 can be easily attached by hand. At the time of locking, even if the engagement of the female locking member 3 and the male locking member 4 is released, the shape of the wire rope 2 is maintained almost as it is, so that the end of the wire lock 1 may be hit against an unexpected object. There is nothing.

On the other hand, in the wire lock 1 described above, only the elastically deformable hard steel wire rod 8 is exposed on the outer surface of the wire rope 2. Will never remain. Moreover, the surface strength of the outer peripheral surface is no different from that of the wire rope using only the hard steel wire, and even if the wire rope 2 comes into contact with the outside, the mild steel wire 7 is not damaged. In the case of the wire lock 1, since the wire rope 2 is further covered with the vinyl tube 5, the wire rope 2 is hardly damaged in the first place.

Although specific examples of the present invention have been described above, various specific configurations of the present invention are possible other than the specific examples described above. For example, in the above specific example, an example in which the wire rope 2 is composed of one soft steel wire rod 7 serving as a core wire and six hard steel wire rods 8 serving as a stranded wire has been described. Various configurations are known, even if they are standardized by the JIS standard, and any of them may be adopted.

Further, if the configuration of the wire rope is changed, the combination of arrangements of the mild steel wire rod and the hard steel wire rod can be appropriately changed. Specifically, for example, as shown in FIG. 2 (b), one core wire and six twisted wires are set as one set, and if the wire rope is a twisted wire using a plurality of sets, The core wire of the set may be the mild steel wire rod 7, and the stranded wire of each set may be the hard steel wire rod 8. In this case, the set used as the outer stranded wire uses the mild steel wire rod 7 and the hard steel wire rod 8 as described above, and all the sets used as the core wire of the shaft are You may use the one that you made. Further, if the mild steel wire 7 and the hard steel wire 8 are used in the set used as the stranded wire on the outer periphery as described above, the core wire of the shaft center may be eliminated. In addition, the mild steel wire rod 7 and the hard steel wire rod 8 may have different diameters. In this way, by appropriately adjusting the number ratio and the outer diameter ratio of the mild steel wire rod 7 and the hard steel wire rod 8, a wire lock suitable for the purpose, such as those with an emphasis on flexibility and strength, can be obtained. You can
