Description

  The present invention mainly relates to piercings used when a police officer or the like controls a criminal, a thief, or other controlled person.

  As a conventional piercing crotch, for example, as shown in FIG. 10, it is composed of a bifurcated heel 104 that branches into a semicircular, U-shaped, V-shaped or the like (semicircular in the figure) at the tip of a handle 101 composed of a stretchable heel 102 or the like. The one formed by attaching the stabbed main body 103 is generally known (see, for example, Patent Documents 1 to 4). In this conventional pierced crotch, a police officer or the like holds the handle portion 101 by hand and presses the torso of the criminal or the like with a fork 104 to thereby restrain the criminal or the like.

However, the conventional piercing has the following problems. (1) Since the conventional pierced crotch is configured to hold down the body of a criminal or the like and suppress it, it can be used effectively in places where there are no barriers such as walls, fences, or fences of buildings. Can not. (2) Since the movement of the criminal or the like cannot be stopped at a position away from the obstacle, there is a risk of escape when holding it down. (3) It took time and effort to hold the criminal and the like pressed with the two-legged heel, such as the next action, that is, handcuffing.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a pierced crotch that can easily suppress and hold down a controlled person such as a criminal even in a place where there are no walls or walls of a building or other obstacles. It is what.

  In order to achieve the above object, the present invention relates to a piercing having a handle portion and a piercing main body provided at the tip of the handle portion, and the piercing step main body has a bifurcated portion having a pair of bifurcated folds. A pair of movable opening and closing rods that are pivotally attached to the distal ends of the two branch rods and are pivotally mounted in a direction that undulates with respect to the branch rods, with the shaft support portion as a fulcrum. And return means for urging the both opening and closing rods to pivot in a direction to stand up with respect to the branch rod, and stopper means for restricting movement of the both opening and closing rods toward the outer side of the bifurcated rod A body restraining rope such as a wire rope having a desired length, with one end engaged with the tip of the one opening / closing rod and the other end engaged with the tip of the other opening / closing rod, The bifurcated heel guides the human torso between the bifurcated heels. Is formed to a size capable of, by pivoting the two closing lever, characterized in that the front end of the bifurcated lever constructed as to open and close at the both opening and closing rod.

  According to the present invention, the tip of the bifurcated heel is closed by both opening and closing rods (however, a space is formed between the tips of the two opening and closing ridges), and the inner portion of the bifurcated heel (between both branch ridges) An endless ring is formed by the rope. The two open / close rods are controlled by the stopper means to move the bifurcated rod outward (turning), and when the pressing force is applied to the bifurcated rod inward, the bifurcated rod is swung in directions away from each other with the shaft support as a fulcrum. By releasing the pressing force, the return means returns to the original position by the action of the return means. Therefore, when the tip of the piercing body is pressed against a target part (for example, the body of a criminal or the like), both the opening and closing hooks pivot in a direction away from each other against the action of the return means, and the tip of the two-pronged hook (both opening and closing hooks) Between the tips of the two) and the target body (body, etc.) is introduced into the inside of the fork. Then, after passing the target body between the tips of the two opening / closing rods, the both opening / closing rods are returned to their original positions by the action of the returning means, and the tip of the two-pronged rod is closed by the both opening / closing rods. As a result, the object is in a state formed in the ring formed by the rope in the bifurcated heel.

  Therefore, when controlling the criminal, etc., if the tip of the piercing body is pressed against the body, etc. of the criminal, the two open / close heels pivot in a direction away from each other to open the front of the fork and open the body to the inside of the two crotch To introduce. Then, after the fuselage passes between the ends of the two open / close rods, the open / close rods are restored by the action of the return means, and the tip of the bifurcated rod is closed, so that the fuselage is in the state of the rope ring. Accordingly, the body of the criminal or the like is restrained by the rope ring and the movement is restricted, so that the criminal or the like can be easily seized.

  In the present invention, the configuration of the return means is not particularly limited as long as it has a function of returning both the opening and closing rods to their original positions when the pressing force to the both opening and closing rods is released. For example, it can be constituted by an elastic traction body such as a coil spring for traction or rubber for traction. Further, the return means may be constituted by a leaf spring that presses the opening / closing rod in a direction to stand up with respect to the branch rod.

  In the present invention, the stopper means is not limited in its configuration as long as both opening and closing rods have a function of restricting the movement of the bifurcated rod in the outward direction. It is possible to adopt a configuration including a stopper plate that is fixedly provided on the tip side of the door and that abuts against a predetermined portion of the opening / closing rod when the opening / closing rod is turned to a predetermined position in a returning direction. Further, in the present invention, the handle portion can be constituted by a multistage stretchable ridge.

  According to the present invention, it is possible to control and easily hold down the controlled person even in a place where there are no walls, walls or other obstacles in the building. Moreover, since the pressure-controlled person can be rolled over by operating, for example, pulling on the handle, it is easy to hold down the criminal.

  Hereinafter, an example of an embodiment of the present invention will be described.
