  However, even if the conventional piercing claw described above can press the bifurcation against the culprit's torso, the culprit violates and resists, or the culprit resists by grabbing the bifurcation or handle of the piercing crotch. As a result, the bifurcated portion pressed against the torso of the criminal comes off and often gets lost before the criminal is captured, making it difficult to completely suppress and capture the criminal. In recent years, there have been an increasing number of incidents where suspicious individuals enter into educational facilities such as elementary schools and cause violent crimes, so the number of educational facilities that deploy piercing as a means of self-defense is increasing. Stitching that can effectively suppress suspicious individuals is desired.

  On the other hand, in order to solve this problem, for example, by providing as many sharp pins as possible, for example, on the outer peripheral surface of the bifurcation portion or handle portion of the piercing crest, the resistance of the criminal when the bifurcation portion is pressed against the trunk portion is reduced. Stitching has been proposed that can suppress or make it difficult for the criminal to grip and resist the bifurcation or handle, and even a powerless woman can effectively suppress the criminal, but the pin provided on this crotch Since one piece is fixed to the outer peripheral surface of the branch part or handle part by welding, for example, if a large number of pins are provided on the outer peripheral surface of the branch part or handle part, the fixing work is performed for each one. There are disadvantages that it is necessary and cumbersome to manufacture, inferior in mass productivity and high in cost.

  In addition, the code | symbol 5 is a grip part 5 which grips the handle | steering-piece part 2 in the figure. The gripping portion 5 is provided in the middle and the base end portion (the end portion on the side opposite to the branching portion 1) of the handle portion 2. Further, the gripping part 5 may be a gripping part 5 having a non-slip function in order to prevent slipping when gripping the handle part 2.

  The branch portion 1 and the handle portion 2 may be integrally formed, or the branch portion 1 and the handle portion 2 provided separately may be joined by an appropriate means.

  Specifically, in this embodiment, after the branch portion 1 and the handle portion 2 are provided separately, both members are joined by welding. In addition, you may use means other than welding for joining of both members. The present embodiment, which is separately provided and then joined by means such as welding, is easier to manufacture than the case of integral molding.

  In the present embodiment, the branch portion 1 is provided with a large number of protrusions 4A.

  Further, in this embodiment, the handle 2 is provided with a number of protrusions 4A.

  Specifically, the projection 4A of the branching portion 1 of the present embodiment is configured to be provided on the entire outer peripheral surface of the branching portion 1. By providing the protrusion 4A on the entire outer peripheral surface of the branch portion 1, the protrusion 4A can be applied to the torso of the person to be captured such as a criminal when the branch portion 1 is pressed. Since it becomes difficult to grasp the hand with a hand or the like, it is possible to exert an excellent effect in suppressing the captured person.

  In addition, the projection 4A of the handle portion 2 of the present embodiment is configured to be provided in a predetermined range on the outer peripheral surface of the handle portion 2 on the tip side (the end portion on the side where the branch portion is provided). By providing the protrusion 4A on the distal end side of the handle part 2, it becomes difficult for a person to be captured such as a criminal to grasp the handle part 2 with a hand or the like.

It is formed by welding the barbed wire 4 and the outer peripheral surface at a plurality of locations.

  In addition to the method of providing a large number of protrusions 4A in a predetermined range by spirally winding the barbed wire 4 having a predetermined length in the present embodiment, the protrusion 4A, as illustrated in FIG. Although it is good also as a structure which provides many protrusions 4A in a predetermined range by providing many things which wound the barbed wire 4 1 turn and fastened for every turn, the barbed wire 4 is wound several times continuously. Thus, the present embodiment, in which a number of protrusions 4A are provided in a predetermined range and only a few points are fixed, is easier to manufacture, has superior mass productivity, and is low in cost.

  Further, the projection 4A of the present embodiment is formed by winding the barbed wire 4 so that, for example, the periphery of the branch portion 1 and the handle portion 2 is difficult in the conventional example in which the pins are fixed to each other by welding or the like. It is easy to form dense protrusions 4A in the direction and the axial direction. That is, by setting the interval and shape of the protrusions 4A provided on the barbed wire 4 or the number of windings of the barbed wire 4, the protrusions 4A on the outer peripheral surface of the branch part 1 and the handle part 2 are densely arranged in the circumferential direction and the axial direction. Any shape can be provided.

  For example, as illustrated in FIG. 4, the pitch when the barbed wire 4 is wound around the outer peripheral surface of the branch portion 1 may be set wide so that the protrusions 4 </ b> A are provided sparsely. Needless to say, the pattern portion 2 can have the same configuration.

  For example, as illustrated in FIG. 5, the protrusion 4 </ b> A may be provided only in a predetermined range on the outer peripheral surface of both ends of the branching portion 1.

  Furthermore, if the barbed wire 4 of the present embodiment is appropriately selected from commercially available products having various protrusions 4A intervals and shapes, the desired number and the desired number of protrusions 4A can be easily obtained without incurring costs. It can be provided in the position.

  It should be noted that the barbed wire 4 and the outer peripheral surface of the branch portion 1 or the handle portion 2 can be fixed to the outer periphery of the barbed wire 4 and the branch portion 1 or the handle portion 2 in addition to the welding of several places in this embodiment. Appropriate means such as full-surface welding of a portion in contact with the surface, adhesion with an adhesive, and metal fitting can be employed. Moreover, it is good also as a structure which provided the concave groove used as the guide at the time of winding the barbed wire 4 in the outer peripheral surface of the branch part 1 or the handle | pattern part 2, and fitted and latched the barbed wire 4 in this concave groove.

  Since the present embodiment is configured as described above, the barbed wire 4 having a predetermined length is spirally wound around the outer peripheral surface of the branch portion 1 and the handle portion 2 to form a large number of protrusions 4A. A large number of protrusions 4A can be easily fixed to the outer peripheral surface by a simple operation of simply welding several portions of the barbed wire 4, so that, for example, a conventional pin is attached to the outer peripheral surface by welding or the like. Compared to the case where it is fastened, it is easy to manufacture, has excellent mass productivity, and is cost-effective.

  Furthermore, in the present embodiment, the projection 4A is provided on the entire outer peripheral surface of the branch portion 1 made of a metal pipe curved in a semicircular shape, and the projection 4A is provided at the tip portion of the handle portion 2. The protrusion 4A can be brought into contact with a person to be captured such as a criminal who is pressed against the branch portion 1, thereby effectively suppressing the resistance of the criminal and the like. It is possible to make it difficult to grip the handle 2 and resist it. Further, in this embodiment, the protrusion 4A is provided by the sharp barbed wire 4 so that the barbed wire 4 can be used as a criminal or the like.
