Abstract

1. A volley ball shooter, comprising a principal chassis (1) and a propulsion mechanism incorporating a striking lever (21), and at least one propulsion spring (27), intended to work the aforementioned lever, characterised in that the device of the arming mechanism consists of a traction cable (15), preferably made of steel, fixed at one end to a striking lever (21) and the other end of which is rolled on a pulley (30), mounted sliding and free rotating on a rotating drive shaft (31), the aforementioned pulley having for its drive a side cam (32) intended to work in conjunction with a wedge (33) fixed on the peripheral edge of the said shaft, and being provided with the means of freeing the end of the winding of the cable (15), in a way that provokes, by the unwinding of the said cable, the automatic detente of the propulsion springs (27), these consisting of a lug (30') which is carried by the pulley (30) and stretches sideways in relation to this, and is supported on a bell cam (35) fixed on and turning concentric around shaft (31), a helicoidal spring (34) surrounding shaft (31) to push back the pulley (30) to its initial position of drive on the aforementioned shaft in a manner to be able to restart a cycle.
