Definitions
- the present invention relates to piercing used mainly as a security or security tool for schools and other various facilities.
- the stabbed crotch is often used by police officers, security guards, and the like who have undergone sufficient training, but in recent years, the ones that are 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.
- 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.
- 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.
- the rotation of the arm in the opening direction is restricted by the lock mechanism, so that the restrained partner cannot open the arm.
- the arm can be directly held and closed without pressing the distal end side of the sliding member against the opponent. 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.
- 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.
- 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. Close to the first unlocking mechanism and any position A second lock mechanism for restricting the rotation in the direction of opening of each arm, and a second unlocking mechanism for unlocking the second locking mechanism by a predetermined operation.
- 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.
- each arm is not closed by the restraint person, so that each arm can be held open until the restraint 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.
