WO2014005239A8 - Device for immobilising a criminal and method for producing said device - Google Patents

Abstract

The invention relates to a device for immobilising a criminal, to a production method and to a method for the use of said device. The concept is based on the fact that, when pressure is applied to the tendons of the wrist, the hand closes into a semi-fist, becoming extremely sensitive, and at this point, the person being held surrenders. This is achieved by the fact that the device activates automatically when placed on the wrist, applying pressure to the tendons and immobilising the arm. The device consists of: a solid mechanised body comprising an upper part and a lower part, the upper part housing a piston sliding inside a bushing and a pressure element; a groove or guide for the piston with a spring and an automatic return trigger; and a sensor including a position recovery spring. In the lower body, a sliding angle moves through the support which contains a fixed piston rod, and the rear part of the lower body contains a hard spring providing the push. The solid body also comprises a locking element that fixes the sliding angle in place, and the lower body contains a lever including a transverse axle that actuates a locking element with a return spring. The transverse axle comprises a lever recovery spring, and the rear part of the lower body houses a pincer bearing a tooth that pivots in a small spring. In turn, the front part of the pincer comprises a master spring that oscillates on the shaft of the moving plate, the rear end of the pincer comprising a safety catch secured by the fixing element of the sliding angle.
