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 shown in FIG. 12, for example, a conventional pierced crotch 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 an extendable 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) Since the body torso is pressed with a bifurcated heel, the movement of the body can be restrained, but the arms and legs can be moved freely. Therefore, it took time and effort to hold down the next action, that is, handcuffing. (4) For example, when controlling a criminal who has a knife such as a knife, the arm can be moved freely, so there is a risk of being stabbed with a knife when holding it down such as handcuffing it.

  Accordingly, the present inventor has developed a piercing (preceding example) configured as follows for the purpose of solving the above problem. The piercing of the preceding example is a piercing with a piercing main body attached to the tip of the handle, and the piercing main body is connected to the tip of the bifurcated heel and the bifurcated heel of the heel, and in a predetermined angle range. A movable opening / closing rod which is relatively set up and down in an approaching / separating direction, a locking means for releasably locking the movement of both opening / closing rods when both opening / closing rods are raised at a predetermined angle, and one end of the one And a restraining rope of an appropriate length that is engaged with the tip of the opening / closing rod and the other end of which is engaged with the tip of the other opening / closing rod. When the both opening and closing rods are raised and lowered, the rope is used to form a ring (see Patent Document 5).

  According to the preceding example, when the piercing body is pressed against a target part (for example, an arm of a criminal, etc.) with both the opening and closing hooks open, a force is applied to the tip of the opening and closing hook through the rope. The open / close saddle is overturned and locked with both ends closed between the two tips. Further, when both the opening and closing rods fall down, an endless ring is formed by the rope. So, for example, when controlling the criminal who has a knife, if the tip of the piercing body is pressed against the arm holding the knife, both the opening and closing hooks will fall down and the arms will be in a ring formed by a rope. Locked in the entered state. Therefore, since the arm holding the blade is restrained by the rope ring and the movement is restricted, the risk of being stabbed by the blade can be eliminated and easily held. Further, when the tip of the piercing body is pressed against the ankle of a criminal or the like, the ankle is locked and restrained in the state of entering the loop of the rope by the same operation as described above. Thereby, since the criminal etc. can be easily rolled over by operating, such as pulling a handle part, a criminal etc. can be easily suppressed similarly to the above.

However, the following examples still have room for improvement. That is, the prior example requires an operation of resetting the movable opening / closing rod to the original position every time it is used. In addition, for example, since the configuration of the locking means and the like is complicated, it takes time for manufacturing and increases the production cost.
Japanese Patent Laid-Open No. 7-103695 Registered Utility Model No. 3083372 Registered Utility Model No. 3041513 Registered Utility Model No. 3083227 JP 2001-289593 A

  In view of the above circumstances, the present invention makes use of the advantages of the previous example and simplifies the configuration by adding improvements, and omits the work of resetting the opening / closing rod as in the previous example, and has a blade. It is an object of the present invention to provide a piercing crotch that can be easily restrained by eliminating the risk of being stabbed by a blade even when controlling a criminal who is present.

  In order to achieve the above object, one of the present inventions (the first invention) is a piercing having a handle and a piercing main body provided at the tip of the knitting, wherein the piercing main body includes: A bifurcated rod having a pair of bifurcated bifurcated rods and a direction in which the base end portion is pivotally supported on the distal end portions of the two bifurcated rods and is undulated with respect to the branched rod as the fulcrum. A pair of movable open / close rods that are pivotably mounted to each other, return means that urges both the open / close rods to pivot in a direction to stand up with respect to the branch rods, and the open / close rods of the bifurcated rod Stopper means for restricting the movement of turning outward, and by turning both the opening and closing rods, the tip of the bifurcated rod is opened and closed by the both opening and closing rods.

  According to the first aspect of the invention, the tip of the bifurcated heel is closed by both opening and closing heels. 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 leg or thigh of a criminal), both the opening and closing heels rotate in a direction away from each other against the action of the return means, Open the opening / closing heel between the tips and introduce the target body (feet, thighs, etc.) into 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 of being in the fork.

  Therefore, when controlling the criminal, etc., if the tip of the piercing body is pressed against the thigh, etc. of the criminal, the two open / close heels pivot in directions away from each other to open the tip of the fork and open the thigh, etc. To the side. Then, after the thighs and the like have passed between the tips of the two open / close heels, the open / close heels are restored by the action of the return means and the tip of the bifurcated heel is closed, so that the thighs and the like are in the bifurcated heel. Therefore, the thighs of the criminal etc. are restrained and the movement is restricted, so that the criminal etc. can be easily seized. In addition, the criminal or the like can be rolled over by pulling the handle or the like in a state where the thigh or the like is put in the bifurcated heel as described above, so that the criminal or the like can be easily held down.

  Among the present inventions, another invention (second invention) is 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 branches into a bifurcated shape. A bifurcated rod having a pair of branch rods and a base end portion attached to the distal ends of the two branch rods, respectively, and pivotable in a direction that undulates with respect to the branch rod using the shaft support portion as a fulcrum. A pair of movable opening / closing rods provided relative to each other, return means for urging the both opening / closing rods to pivot in a direction to stand up with respect to the branch rod, and the both opening / closing rods pivoting outward of the bifurcated rod A stopper means for restricting the movement of the wire, and a wire rope of a desired length provided 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. A restraining rope, and by turning both the opening and closing rods Characterized in that to constitute a tip of the bifurcated lever so as to open and close at the both opening and closing rod.

  According to the second invention, the tip of the bifurcated rod is closed by both opening and closing rods, and an endless ring is formed by the rope on the inner part of the bifurcated rod (between both branch rods). 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 arm or ankle of the criminal), both the opening and closing heels rotate in a direction away from each other against the action of the return means, Open the gap between the tips of the open / close barbs and introduce the target body (arms, ankles, etc.) to the inside of the bifurcated bark. 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.

  So, for example, when controlling the criminal who has a knife, if the tip of the piercing body is pressed against the arm holding the knife, the two open / close hooks turn in directions away from each other to open the tip of the fork Introduce the arm to the inside of the fork. Then, after the arms pass between the ends of the two opening / closing rods, the both opening / closing rods are restored by the action of the return means and the tip of the bifurcated rod is closed, so that the arms are in the state of the rope ring. Therefore, since the arm holding the blade is restrained by the rope ring and the movement is restricted, the danger of being stabbed by the blade can be eliminated and the criminal or the like can be easily held down. Further, when the tip of the piercing body is pressed against the ankle of a criminal or the like, the movement of the ankle is restricted by the same operation as described above in a state where the ankle enters the loop of the rope. Thereby, since the criminal etc. can be easily rolled over by operating, such as pulling a handle part, a criminal etc. can be easily suppressed similarly to the above.

  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.

  The present invention has the following effects. (1) The production cost can be reduced by simplifying the configuration as compared with the preceding example. (2) The work of resetting both open / close rods can be omitted. (3) The criminal can be controlled and easily seized. (4) In particular, according to the second invention, the risk of being stabbed by the cutter can be eliminated and restrained even when the criminal or the like holding the cutter is suppressed.

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

  The both opening / closing rods 23 are respectively attached to a bearing member (described later) provided at a distal end portion of both branch rods 22 with a base end portion (a portion slightly on the distal direction side from the base end 23b) supported by a shaft 27. The shaft support portion (the shaft 27) is provided as a pivot so as to be pivotable in a direction in which the branch rod 22 is raised and lowered. Then, by turning both the opening / closing rods 23, the tip of the bifurcated rod 21 is configured to be opened / closed by the both opening / closing rods 23. That is, when the both opening / closing rods 23 stand up and the tips 23a of the both rods 23 approach each other (when the axis of the both opening / closing rods 23 is located on substantially the same straight line), the tip of the bifurcated rod 21 is closed. Since both the opening / closing rods 23 are separated from each other by turning the both opening / closing rods 23 in a direction in which they lie down with respect to the branch rods 22, the tip of the two-pronged rod 21 is opened.

  The both opening / closing rods 23 are moved so that the both rods 23 turn outward from the position where the tip of the two-folding rod 21 is closed, that is, the posture where the axes of the both opening / closing rods 23 are located on substantially the same straight line. Is restricted by the stopper means 25. Thereby, both the opening and closing rods 23 are configured to be turnable only in the inner direction of the bifurcated rod 21 from a position where the axes of the both rods 23 are substantially on the same straight line (can be raised and lowered with respect to the branch rod).

The first embodiment includes a bearing member 28 that pivotally supports the opening / closing rod 23 and an attachment member 29 that fixes and attaches the member 28 to the tip of the branch rod 22. As shown in the most detail in FIG. 5, the bearing member 28 has a pair of bearing plates 30, 30 of an appropriate size and arranged in parallel with an interval corresponding to the thickness of the branch rod 22, and both plates 30. And a stopper plate 31 provided by connecting the upper ends on the front end side at right angles. The both bearing plates 30 are positioned near the upper end of the stopper plate 31 on the rear portion side, and are provided so as to be opposed to the both plates 30, and are positioned on the rear portion side of the shaft hole 32 and vertically. There are provided screw insertion holes 33 and 33 provided in a plurality of sets (two sets in the figure) opposite to both plates 30 with an appropriate interval in the direction.
The mounting member 29 includes a pair of mounting plates 34 and 34 having an appropriate width and length that are opposed to each other with an interval to be engaged with the outer surfaces of the both bearing plates 30, and the rear ends of the both plates 34. Are connected to each other at a right angle. Both the mounting plates 34 have screw insertion holes 36, 36 that are located on the tip end side of the plate 34 and that are opposed to both the plates 34 so as to correspond to the screw insertion holes 33, 33. .

  The two branch rods 22 have screw insertion holes 37, 37 that are located on the distal end side of the rod 22 and are provided through the flange 22 so as to correspond to the screw insertion holes 33, 33. Further, the both opening and closing rods 23 have shaft holes 38 which are located at the base end portion of the rods 23 and are provided through the rods 23.

  Then, the both bearing members 28 are engaged with the both bearing plates 30 at the distal end portion of the branch rod 22 with the stopper plate 31 facing the inner side of the bifurcated rod 21, and both the mounting members 29 are The connecting plate 35 is engaged with the outer surfaces of the two bearing plates 30 in a state where the connecting plate 35 faces the outer side of the fork 21. In this state, the screw rod 39 is inserted through the screw insertion holes 36, 33, 37 of the mounting member 29, the bearing member 28, and the branch rod 22, and the nut 40 is fastened and fixed. Thus, the bearing members 28 are fixedly provided at the distal ends of both branch rods 22.

  Further, the both opening and closing rods 23 face the shaft hole 38 in a direction that matches the shaft hole 32 of the bearing member 28, and the inner side surface (the lower side surface in FIG. The base end portions of the two open / close rods 23 are both bearings so as to be in contact with the distal end surface and the outer surface (upper side surface in FIG. 3) of the flange 23 is in contact with the inner surface of the stopper plate 31.

In this state, the shaft 27 is inserted through the shaft holes 32 and 38 of the bearing member 28 and the opening / closing rod 23, and the opening / closing rod 23 is tightened by the nut member 41 so that the opening / closing rod 23 is rotatable. It is attached to the member 28. As a result, the opening and closing rods 23 are pivotally supported by the shafts 27 at the base ends, and the movement of turning outwardly of the bifurcated rods 21 is restricted by the stopper means 25, that is, the distal end surfaces of the stopper plates 31 and the branch rods 22. It is configured to be rotatable only in the inner direction of the bifurcated rod 21 (can be raised and lowered with respect to the branch rod).

  The stopper means 25 of the first embodiment is constituted by the stopper plate 31 of the bearing member 28 and the distal end surface of the branch rod 22 as described above.

  The return means 24 turns both the opening and closing rods 23 in the direction to stand up with respect to the branch rods 22 to return them. As shown in FIG. 3 in detail, the return means 24 of the first embodiment is constituted by a traction coil spring 24a. Then, one end of the spring 24a is fastened to the base end portion of the opening / closing rod 23 with a screw 42, and the other end is fastened to the outer surface of the distal end portion of the branch rod 22 at an appropriate position with a screw 43. A spring force is applied so that the base end surface is pulled toward the branch rod 22 side. As a result, when a pressing force in the inner direction of the two-pronged rod 21 is applied to both the opening and closing rods 23, both the rods 23 pivot in directions away from each other against the action of the spring 24a, and the pressing force is released. Thus, the spring 24a is configured to return to the original position.

  The restraining rope 26 is formed in a length that forms a ring 44 of an appropriate size on the inner side of the bifurcated rod 21, and one end of the rope 26 is engaged with the tip of one opening / closing rod 23 and the other end thereof. The other opening / closing bar 23 is engaged with the tip. As shown in detail in FIG. 6, the rope 26 according to the first embodiment includes a wire rope 45 having an appropriate length, and a sheath tube 46 made of a flexible synthetic resin and the like that is fitted to the rope 45. .

The both ends of the wire rope 45 are engaged with the both ends 23 by engaging with each other.

  With the above configuration, when both the opening and closing rods 23 stand up with respect to the branch rod 22, that is, when the ends of the two-folded rod 21 are closed by the both opening and closing rods 23, the inner portion of the two-folded rod 21 by the rope 26. Thus, an endless ring 44 is formed. A target part 49 (an arm, an ankle, etc.) such as a criminal is put in the ring 44 and restrained. The cladding tube 46 is provided to protect the arm, ankle, etc. of the criminal when the criminal is restrained.

  The pierced crotch according to the first embodiment is configured as described above. Next, an example of the method of use and the operation will be described. For example, when suppressing a criminal or the like holding a knife, when the tip of the piercing body 2 is pressed so that the arm 49 holding the knife is sandwiched between the two branch rods 22, as shown in FIG. Swivels away from each other to open the tip of the fork 21 and introduce the arm 49 into the inside of the fork 21. When the arm 49 passes between the tips of the two opening / closing rods 23, the both opening / closing rods 23 are restored by the spring action of the restoring means 24 and the tip of the bifurcated rod 21 is closed. It will be in the state inside. Therefore, since the arm 49 holding the blade is restrained by the ring 44 of the rope 26 and the movement is restricted, the danger of being stabbed by the blade can be eliminated and the criminal or the like can be easily held down. When the tip of the piercing body 2 is pressed against the ankle of a criminal or the like in the same manner as described above, the ankle is restrained in a state where it enters the ring 44 of the rope 26 by the same operation as described above, and the movement is restricted. Thereby, since the criminal or the like can be easily rolled over by operating the pulling of the handle 1 or the like, the criminal or the like can be easily held down as described above.

  Further, since the stopper means 25 of the first embodiment is constituted by the stopper plate 31 of the bearing member 28 and the tip surface of the branch rod 22, the movement (turning) of the both opening and closing rods 23 in the outward direction is ensured. Can be regulated. Furthermore, the stopper means can be configured to be robust.

  In the first embodiment, an example in which the bearing member 28 and the mounting member 29 are configured separately is disclosed, but a configuration in which both the members 28 and 29 are integrated may be employed.
