Description

  The present invention relates to stabbed criminals who may or may not have a weapon such as knives. In particular, the criminals should be secured while maintaining their own safety by keeping a distance from the criminals. The present invention relates to piercing that can be suppressed.

  The piercing is basically a structure in which a U-shaped suppression member is attached to the end of a long bar. When suppressing a rampant criminal, etc., the U-shaped The pressure-suppressing member is directed toward the criminal or the like, and is pressed against the heel or wall with the U-shaped portion sandwiching the trunk or throat.

  However, in such a conventional piercing crotch where only a U-shaped suppression member is attached to the end of a long bar, it is difficult to suppress criminals etc. where there is no wall behind, and a simple long bar is used. It may only have the same effect as Therefore, some proposals have been made to deal with such problems.

  One of them is a piercing crotch comprising a generally U-shaped curved arm that captures the body at the tip of the gripping rod, and can be bent only at the center of the curved arm at both ends of the curved arm. Two movable arms that can be automatically returned by a spring mechanism are provided so that the open part of the curved arm is closed as short as possible, and the piercing crotch is configured so that it cannot accommodate and remove the body (Patent Document 1) This is a proposal.

  According to this piercing crotch, when a movable arm that closes the curved arm distal end opening portion is pressed in an attempt to constrain the body of a criminal or the like with the curved arm, this rotates to the inside of the curved arm to open the part. Therefore, if this is used in a proper manner, it seems that a criminal or the like can be relatively easily put in the curved arm. However, the criminal or the like performs various violent actions at this time for escape or counterattack, and the movable arm is obstructed by any part of the body of the criminal or the like. For example, the criminal may not be able to easily return to the original position, and the criminal or the like cannot easily be completely restrained in the curved arm.

Furthermore, another one is a main body frame, a long rod attached to the front side of the main body frame, and a sliding body slidably attached to the front end side of the main body frame along an extension line of the long rod, A left semi-annular body and a right semi-annular body whose root portions are rotatably attached to the sliding body, and a relative positional relationship between the left semi-annular body and the right semi-annular body in conjunction with the sliding motion of the sliding body With an interlocking mechanism that changes
When the sliding body is located on the distal end side, an open state is formed so that a person to be captured can freely pass between the distal end portions of the left semi-annular body and the right semi-annular body,
When the sliding body is positioned on the near side, a closed state is formed so that a person to be captured cannot freely pass between the front end portions of the left semi-annular body and the right semi-annular body, and this state is a locking means. This is a proposal of a stab-type catching tool (Patent Document 2) that is configured to be locked by the robot.

  According to this stab-type catching tool, with its left and right half-annular bodies at the tips open, it faces the criminals and other detainees and puts its torso or neck inside both of them. When it is pressed while being in the state, the sliding body comes into contact with the torso or neck of the person to be captured, and this moves backward to close the front end side of the left semi-annular body and the right semi-annular body. Make it work.

  Thus, according to this stab-shaped catch tool, the person to be captured can be restrained relatively easily, but the ring formed by the left and right hemicycles is locked at a specific closing point. The diameter cannot be set freely. Therefore, depending on the body shape of the prisoner, the restraint may be too loose or too tight. In particular, if the diameter is set on the premise of restraining the body part, it becomes an object that is not suitable for restraining the neck part, and there is a possibility that it may not be able to endure the use of flexibility.

  In addition, this stab-type catching tool has a problem that its configuration is slightly complicated.

  The present invention solves the above-mentioned problems of the prior art, and can be used without a wall or a flaw behind the restraint object of a criminal or the like, and the configuration of the tip thereof makes it easy and reliable. It is another object of the present invention to provide a pierced crotch that can be restrained freely and the diameter of the rear side thereof can be freely changed according to the body shape of the restrained person or according to the restrained part.

In the first aspect of the present invention, a support member perpendicular to the support rod is disposed at the tip of a rectangular tube-shaped gripping rod, and the rear ends of the partial arc-shaped holding pieces are rotatably coupled to both ends of the support member. A rectangular tube-like actuating rod is inserted into the gripping rod from the tip so as to be able to advance and retreat, and actuating pieces are pivotally connected to both sides of the tip of the actuating rod, and the tips of the actuating pieces are respectively connected to the holding pieces. In the middle of
Further, the advancement / retraction operation can be temporarily fixed to the operating rod and the gripping rod at a fixed position in the most advanced state of the operating rod, and from the fixed position in the most advanced state to the fixed position in the last retracted state. While being free to retreat at a plurality of locations, the advancement can be temporarily fixed, and at the same time, it is a piercing crotch provided with a temporary fixing means capable of releasing the temporary fixation at each position freely.

  2 of the present invention is the piercing device according to claim 1, wherein the temporary fixing means includes a temporary fixing hole opened in the vicinity of the rear end on the peripheral side of the operating rod, and a front end from the temporary fixing hole on the peripheral side. A plurality of short temporary fixing holes having a shorter length than the temporary fixing holes arranged at regular intervals to a certain position on the side, and the same size as the temporary fixing holes opened on the proximal side on the peripheral side of the gripping rod An introduction hole and a fixing member that is disposed outside the peripheral side of the gripping rod, and can be fitted into a temporary fixing hole that is positioned at a position corresponding to the introduction hole through the introduction hole; and A stepped portion which is located on the inner surface of all the fixing portions and is engaged with a short temporary fixing hole which is located at a position corresponding to this through the introduction hole on the rear end side, and a front end side from the highest position of the stepped portion. A semi-fixed portion consisting of a sliding surface that is inclined downward toward the surface, and the entire fixed portion and the semi-fixed portion through the introduction hole. A reciprocating operation unit is moved forward and backward to be temporarily fixed holes or short-sized temporary fixing hole has a be, in those configured.

  3 of the present invention is a bracket that supports the advancement / retraction operation part in the piercing of 2 of the present invention, and a grip bar extending from the back surface of the whole fixed part, and a midway of the grip bar so as to be able to swing up and down. Between the bracket fixed to the peripheral side of the gripping rod, the portion of the gripping rod opposite the fixed portion and the peripheral side of the gripping rod facing the portion A compression type spring member.

  According to the piercing of 1 of the present invention, it can be used even if there is no wall or wrinkle behind the constrained person such as a criminal, and the pair of partial arc-shaped holding pieces at the tip part thereof are restricted. A reliable restraining operation is possible regardless of the movement of the person, and in addition, depending on the size of the part such as the neck or torso of the person to be restrained or according to the body shape of the person to be restrained, Since the diameter formed by the holding piece can be freely changed, the person to be restrained can be restrained safely and reliably with an appropriate diameter. In addition, since the holding rod is a rectangular tube type, unlike the cylindrical type, it is easy to reliably support in the rotation direction.

  When restraining a person to be restrained such as a criminal, the pair of holding pieces at the tip of the gripping rod are opened with the operating rod advanced to the most advanced state, and then directed to the subject to be restrained. At this time, the operating rod cannot be advanced or retracted by the temporary fixing means. In this state, quickly put the torso of the person to be restrained between a pair of holding pieces, press the tip of the central operating rod, and operate the temporary fixing means at this moment to allow its retraction Then, the operating rod is moved backward to cause the pair of holding pieces to hold the person to be restrained.

  Since the operating rod is fixed in the most advanced state by the temporary fixing means, the operating rod is pushed by the restraining person when the piercing stick is projected toward the restraining person. There is no problem that the pair of holding pieces are closed before holding the trunk or the like.

  When the operating rod cannot be moved back and forth in the most advanced state, it is released by operating the temporary fixing means, and after slightly retracting, the operating rod moves in the retracted direction at each of the plurality of positions. Passing through to the last retreat position can be performed freely, and if any of the plurality of positions is exceeded in the advance direction, it is impossible to move beyond each of them. Accordingly, the pair of holding pieces can operate only in the holding tightening direction. In addition, as described above, since the movement of the operating rod in the advancing direction is prevented at the plurality of locations, it is possible to fix the holding state of the pair of holding pieces in the corresponding open state (diameter). Yes, the person to be restrained can be surely held and restrained with an appropriate diameter.

  Therefore, the above-described effects can be reliably achieved.

  According to the second piercing of the present invention, the temporary fixing means can be realized with a simple configuration that operates reliably.

If the gripping action of the gripping rod 14a is stopped immediately after the operating rod 4 is retracted more than the distance to the next short temporary fixing hole 4b in this way, the step of the semi-fixed portion 13b formed on the front surface of the total fixed portion 13a. The highest position of the portion 13b1 is locked to the front end of one of the short temporary fixing holes 4b of the operating rod 4, or comes into contact with the peripheral side surface in front of that of the operating rod 4.

  After this, as shown in FIG. 2 (c), the operating rod 4 is then locked to any short temporary fixing hole 4b by the stepped portion 13b1 formed in the semi-fixed portion 13b of the fixed portion 13. By doing so, the pull-out is prevented, and the backward movement is such that the sliding surface 13b2 which is the inclined surface of the semi-fixed portion 13b slides through the edge on the outer end side of the short temporary fixing hole 4b. Because it can, it will be allowed.

  Therefore, after the above, the pair of holding pieces 3 and 3 can operate only in the holding tightening direction. Further, as described above, since the plurality of short temporary fixing holes 4b, 4b,... Prevent movement of the actuating rod 4 in the advancing direction, the pair of holdings in the corresponding open state (diameter). The holding state of the pieces 3 and 3 can be fixed, and the person to be restrained can be reliably held and restrained with an appropriate diameter.
