Description

  The present invention relates to piercing used mainly as a security or security tool for schools and other various facilities.

  Conventionally, as this kind of stab crotch, an arm that extends in a bifurcated shape on both sides is attached to the end of a long handle, and when holding a thief or a criminal, the handle is gripped and the stab crotch body is pressed against the opponent's torso Thus, there is known one that suppresses a resisting opponent (for example, see Patent Document 1).

  By the way, the stabbed crotch is often used by police officers, security guards, and the like who have undergone sufficient training, but in recent years, those deployed for crime prevention in schools and other general facilities are increasing. However, it has been difficult for the school faculty members and general public who are unfamiliar with the handling to effectively suppress the opponent who resists by simply pressing the arm against the opponent.

  Therefore, there has been known one in which the other party is restrained by a pair of openable and closable arms attached to the tip end side of the handle (see, for example, Patent Document 2).

  This piercing crotch includes a sliding member provided on the handle so as to be slidable in the axial direction, and a link connecting the tip end side of the handle and each arm, and the tip end side of the sliding member is opened with the arm open. When pressed against the opponent, the sliding member moves backward with respect to the handle, and the arm closes inward in conjunction with the link and the sliding member, and the opponent is restrained by the closed arm. Further, when the arm is closed, the rotation of the arm in the opening direction is restricted by the lock mechanism, so that the restrained partner cannot open the arm.

  However, in the piercing crotch in which the arm is opened and closed as described above, the arm can be directly held and closed without pressing the distal end side of the sliding member against the other party. For this reason, if the arm is grabbed and closed by the opponent before the opponent is positioned between the open arms, the arm is locked in the closed state by the locking mechanism. There was a problem that could not be.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to close the arm to the restraint person before restraining the restraint person even in a configuration in which the openable / closable arm is closed and the opponent is restrained. It is to provide a crotch that cannot be closed.

  In order to achieve the above object, the present invention provides a pair of a handle gripped by a user, a sliding member provided on the handle so as to be slidable in the axial direction, and one end rotatably connected to the sliding member. Arm, and a link connecting the tip end side of the handle and each arm. When the tip end of the sliding member is pressed against the person to be restrained, the sliding member moves relative to the handle, and each arm is linked. And a piercing crotch that is closed in conjunction with the sliding member, and is provided on the distal end side of the sliding member so as to be movable in the axial direction and urged in the pressing direction against the restraint person, and a predetermined member A first lock mechanism that restricts the rotation of each arm that is opened to the rotation position in the closing direction, and the lock of the first lock mechanism is released by pushing the pressing member into the sliding member to a predetermined position. 1st unlocking mechanism and closed to any position And it includes a second locking mechanism for restricting the rotation in the direction of opening of the arms, and a second unlocking mechanism for unlocking the second locking mechanism by a predetermined operation.

  Thereby, when each arm is opened to a predetermined rotation position, the first lock mechanism restricts the rotation of each arm in the closing direction, so that the person to be restrained can hold the arm and close it. Absent. Further, when the pressing member is pressed against the subject to be restrained and the pressing member is pushed to the predetermined position with respect to the sliding member, the lock of the first lock mechanism is released by the first lock release mechanism, and each arm is closed. The person to be restrained is restrained. At this time, since the second locking mechanism restricts the rotation of each arm in the opening direction, the restraint person cannot open each arm. Further, by operating the second unlock mechanism, the second lock mechanism is unlocked by the second unlock mechanism, and each arm can be opened.

  According to the piercing of the present invention, the arms to be restrained are not closed with the arms, so that the arms can be held in an open state until the restraining subjects are positioned between the arms. Thus, before the restraint target person is positioned between the arms, the restraint target person is not able to restrain the restraint target person by closing each arm, and suppresses the restraint target person such as a gangster. It is extremely advantageous in some cases.

Is released, and the lock of the first lock mechanism 60 is released as shown in FIG.

  The second lock mechanism 80 is provided in the first lock member 81 fixed to the proximal end of the shaft 20, the second lock member 82 fixed in the handle 10, and the first lock member 81. The first locking member 81 is slidably inserted into the second locking member 82. The first locking member 81 includes a locking member 83 and a number of locking portions 84 provided on the second locking member 82. The first lock member 81 is formed such that both sides in the width direction are bent at right angles, and the second lock member 82 is formed in a rectangular tube shape. The locking member 83 is formed so that both sides in the width direction bend at right angles, and are attached to both side surfaces of the first lock member 81 so as to be rotatable via a support shaft 83a. In this case, the locking member 83 is urged so as to rotate to the outside of the first lock member 81 by a coiled spring 83b attached to the support shaft 83a. Each locking portion 84 is arranged in the axial direction of the handle 10 and the shaft 20, and is integrally formed with a third lock member 85 fixed to the inner surface of the second lock member 82. In this case, each locking portion 84 is formed of a mountain-shaped protrusion that the locking member 83 locks in only one axial direction of the handle 10 and the shaft 20. That is, when the first locking member 81 is disposed in the second locking member 82, the locking member 83 is pressed against the third locking member 85 by the spring 84 as shown in FIG. The locking portion 84 is locked.

  In the second lock mechanism 80, as shown in FIG. 12, when the shaft 20 moves to the base end side (the other in the axial direction) of the handle 10, the locking member 83 gets over the locking portion 84 against the spring 83b. The third lock member 85 is moved to an arbitrary position while being displaced. Further, with respect to the movement of the shaft 20 toward the distal end side (one axial direction) of the handle 10, the locking member 83 is locked to the locking portion 84, and the movement of the shaft 20 in the same direction is restricted. The rotation of the arm 4 in the opening direction is restricted.

  The second lock release mechanism 90 includes a lock release member 91 that can be inserted between the lock member 83 of the second lock mechanism 80 and each lock portion 84, and the lock release member 91 as a shaft of the handle 10. And an operation unit 92 that moves in the direction. The unlocking member 91 is composed of a pair of rod-like members that are spaced apart from each other in the width direction, and the tip thereof is sharply formed. The operation unit 92 is made of a cylindrical member that can be gripped with fingers, and is disposed outside the handle 10. In this case, a long hole 12 extending in the axial direction is provided in the peripheral surface of the handle 10, and the operation portion 92 is connected to the proximal end side of the locking release member 91 via a rod-like connection member 92 a. The operation portion 92 is biased toward the proximal end side of the handle 10 by the spring 93, and when the operation portion 92 is moved toward the distal end side of the handle 10, the operation portion 92 is returned to the proximal end side of the handle 10 by the spring 93. It is like that. One end of the spring 93 is connected to the operation portion 92, and the other end is connected to the proximal end side of the handle 10. A cover member 94 that covers the long hole 12 is provided outside the handle 10. The cover member 94 is a cylindrical member that is slidably provided on the outer peripheral surface of the handle 10, and the connecting member 92 a is inserted through a hole 94 a provided on the peripheral surface of the cover member 93. In this case, when the operation unit 92 is moved along the long hole 12, the cover member 94 is also moved together with the operation unit 92.

  In the second unlocking mechanism 90, when the operating portion 92 is moved along the elongated hole 12 toward the distal end side (one axial direction) of the handle 10, the unlocking member 91 and the locking member 83 are moved as shown in FIG. 13. Inserted between the locking portion 84 and the locking between the locking member 83 and the locking portion 84 is released, and the lock of the second locking mechanism 80 is released as shown in FIG. Yes.

  In the stabbing crotch 1 configured as described above, each arm 30 is locked in an open state by the first lock mechanism 60 by opening each arm 30 to a predetermined position as shown in FIG. Here, for example, when trying to suppress the opponent B such as a thug entering a facility such as a school, the user A holds the handle 10 so that the handle 10 is substantially horizontal as shown in FIG. Next, as shown in FIG. 16, the opponent B as a restraint person is positioned between the arms 30, and the pressing portion 51 of the pressing member 50 is pressed against the opponent B, so that it is indicated by a white arrow in the figure. A pressing force toward the shaft 20 is applied to the pressing member 50. As a result, the pressing member 50 is pushed into the shaft 20, and the lock of the first lock mechanism 60 is released by the first lock release mechanism 70. When the lock of the first lock mechanism 60 is released, the shaft 20 moves toward the proximal end side of the handle 10 as shown in FIG. 10, and each arm 30 wraps the opponent B as shown in FIG. Close to. At that time, each arm 30 is locked in the closed state by the second lock mechanism 80, so that the partner B cannot open each arm 30, and the partner B is restrained by each arm 30. As a result, the user A can hold the opponent B, but may leave it as it is and escape. In this case, since the piercing crotch 1 remains attached to the opponent B, the piercing crotch 1 becomes an obstacle even when trying to follow the user A, and the user A can easily escape from the opponent B.

  On the other hand, even if each arm 30 is gripped by the opponent B as shown in FIG. 18 before the opponent B is positioned between the open arms 30, each arm 30 is opened by the first lock mechanism 60. Since it is locked in the state, unless the pressing member 50 is pushed in, the opponent B cannot be closed with each arm 30 as shown by the white arrow in the figure. As a result, each arm 30 is not closed by the opponent B and the opponent B cannot be restrained.

  When returning each closed arm 30 to the open state, as shown in FIG. 13, when the operation portion 92 of the second unlocking mechanism 90 is moved toward the distal end side of the handle 10, The mechanism 80 is unlocked, the shaft 20 moves as shown in FIG. 14, and each arm 30 opens to a predetermined rotation position as shown in FIG.

  As described above, according to the piercing of the present embodiment, the first lock mechanism 60 that restricts the rotation of each arm 30 that is opened to a predetermined rotation position in the closing direction, and the pressing member 50 with respect to the shaft 20. And the first lock release mechanism 70 for releasing the lock of the first lock mechanism 60 by pushing it to a predetermined position. Therefore, each arm 30 is not closed with the arm 30 held by the counterpart B. Each arm 30 can be held in an open state until the opponent B is positioned between them. Thus, before the opponent B is positioned between the arms 30, the opponent B cannot close the opponent B by being closed by the opponent B, and the opponent B such as a thug is controlled. Very advantageous.

  Further, when the pressing member 50 is pressed against the counterpart B positioned between the arms 30 and the arms 30 are closed, the second lock mechanism 80 restricts the rotation of the arms 30 in the opening direction. B cannot open each arm 30, and the other party B can be firmly restrained by each arm 30.

  In this case, since the second lock mechanism 80 has a large number of locking portions 84 arranged in the axial direction of the shaft 20, the interval between the locking positions of the locking members 83 and the locking portions 84 is set. It can be finely made in multiple stages, and each arm 30 can be crimped to the opponent B without loosening according to the body shape and physique of the opponent B.

  Furthermore, since the second lock release mechanism 90 that releases the lock of the second lock mechanism 80 by the operation of the operation unit 92 is provided, for example, after restraining the training partner with each arm 30 during use training of the piercing crotch 1, Each arm 30 can be quickly unlocked by the second unlocking mechanism 90, and use training of the piercing crotch 1 can be performed smoothly.

  Further, since the long hole 12 for moving the operation unit 92 is covered with the cover member 94 provided on the outer peripheral surface of the handle 10, foreign matters such as external dust enter the inside of the handle 10 from the long hole 12. Therefore, it is possible to effectively prevent malfunction due to the entry of foreign matter.
