Device for Synchronizing the Unwinding of Blocks of Tension Cables of Resilient Elements of a Compound Bow During Shooting

Abstract

A device for synchronizing unwinding of tensioning cable units on resilient elements of a compound bow during firing comprises two synchronizing rollers connected to each other by a synchronizing cable. One of the rollers is attached to a rotation shaft of a tension cable block of an upper resilient member, and the other roller is connected to a rotation shaft of the tension cable blocks of a lower resilient element. Each rotation shaft is mounted in bearings provided in upper and lower supports. The shafts and/or supports are fastened to the respective upper and lower ends of a rigid body of the bow from the rear side thereof. Free ends of the tension cables of the upper and lower tension cable blocks are provided with a connecting/engaging element for connecting the cables to the resilient ends of the lower and upper resilient elements for tensioning the resilient elements from the front side of the bow.

1 . A device for synchronizing unwinding of tensioning cable units of resilient elements of a compound bow during shooting, comprising:
 two synchronizing rollers interconnected to each other by a synchronizing cablelements respectively is attached to a rotation shaft of a tension cable block of the cable of an upper resilient element, and another of said rollers is connected to a rotation shaft of the tension cable blocks of a lower resilient element, each said rotation shaft is installed respectively in bearings of upper and lower supports, said shafts are being fastened to corresponding upper and lower ends of a rigid body of the bow from a rear side thereof, wherein free ends of the tension cables of the upper and lower tension cable blocks are provided with a connecting/engaging element for connecting said cables to the resilient ends of the lower and upper resilient elements respectively for tensioning said resilient elements from the front side of the bow.   
     
     
         2 . The device according to  claim 1 , wherein said connecting/engaging element is formed of a loop, a knot or a turnbuckle. 
     
     
         3 . The device according to  claim 1 , wherein the flexible elements can be selected from the group comprising springs, resilient plates, hydraulic, pneumatic or magnetic accumulators of potential energy of the resilient elements tension.
