Abstract:
1. A system for charging a bolt of a grenade launcher, wherein the bolt of the grenade launcher is charged when the charging bolt is fully drawn along a linear path, the system comprising: a charging assembly including a frame attachable to a grenade launcher, a chain supported by the frame and extending between a proximal end and a distal end, the distal end of the chain being configured to move a bolt of the grenade launcher; and a crank assembly operably coupled to the charging assembly, the crank assembly including a handle, a sprocket, and a pivot pin coupled to the handle and the sprocket for rotating the handle and the sprocket about a pivot axis defined by the pivot pin; wherein the proximal end of the chain is coupled to the sprocket at a sprocket radius from the pivot axis such that when the handle and the sprocket rotate around the pivot axis, the chain moves the bolt along a linear draw length, and the sprocket radius has a value large enough such that rotating the handle and the sprocket by an angle of rotation less than one full rotation around the pivot axis defines an arc length sufficient to fully draw the charging bolt along the linear draw length.
