Semiautomatic operated handcuffs with pivotal arcuate blades

摘要

Disclosed is a handcuff with a set of arcuate blades that are pivotally mounted at opposite ends of a single rectangular box-like casing. A set of telescoping handles, for slidable movement, is supported by a set of internally mounted cam assemblies. The cam assembly has concave cam surfaces. As the rectangular box-like casing bumper makes contact against the suspect's wrist, the officer will apply a forward movement of the telescoping handles. This forward movement of the handle and cam assembly causes the cam's concave surfaces to engage with the pivotal blade rollers. This will cam the blade rollers and rotates the first arcuate blade in a clockwise direction and the second blade in a counter clockwise direction encircling the suspect's wrist. To open the arcuate blades, one would insert and rotate a key to release the cam locking assembly. Unlocking it will simultaneously allow the cam spring to automatically retract the handcuff's handles and the arcuate blades' springs to rotate the arcuate blades to the open and ready-to-use position.
