Description

  The present invention relates to a pierced crotch for securing a capture target person such as a criminal, and relates to a pierced crotch having an opening / closing function and capable of easily capturing the capture target person.

Conventional piercing has a bifurcated tip. When securing capture subjects, a plurality of piercings were used to hold the capture subjects.
However, it has been difficult to capture the person to be captured with a single stab. This is because the conventional pierced crotch does not have an opening / closing function, so that the person to be captured can escape away from the pierced crotch.
As an invention about a piercing crotch having a function of capturing a person to be captured, there has been an invention of a piercing that opens and closes by providing a sliding body having a spring and pressing the sliding body against the person to be captured (see, for example, Patent Document 1). ). However, the invention has a problem that the configuration is complicated and expensive.
In addition, there was an invention in which a restraint member was inserted into a sheath-like pressing portion and a restraint member was taken in and out with a wire or the like, and an invention having a function of locking by being connected to a distal end portion of the restraint member (for example, (See Patent Document 2). However, since the invention requires a highly accurate part, there is a problem that much labor and man-hour are required for manufacturing the part.
There has also been an invention of an open / close type trapping device comprising a safety device lever, a capturing lever, and a movable lever (see, for example, Patent Document 3). However, such an invention cannot be easily opened once it is closed, and there is a problem that it cannot be easily reusable when it is closed by pressing a standing tree, a telegraph pole, a pillar, or the like.
In addition, both the conventional piercing and the inventions of Patent Documents 1 to 3 give a large impact to the opponent when the capture target person is struck at the tip in the case where the capture target person cannot be captured at the center. It had the problem of hurting the capture target and the problem of not being able to capture the capture target.
