US 9,316,458 B2 · Elastomerically self-grasping spear holder for underwater sling

Abstract

An elastomerically self-grasping spear holder for an underwater sling. A cylindrical spear holder has a ring-shaped front part, a solid rear part and a center part containing only two support arms of limited circumferential extent. An elastomeric constrictor placed over the support arms has sides that have a smaller dimension than the diameter of the spear holder. When a spear is placed within the spear holder, the sides of the elastomeric constrictor grip the spear by compression so that the spear is held in position without being held by the operator. The rear part of the spear holder is solid, with a recess on the front surface to receive the rear end of the spear, and a through hole to receive the elastic band connected to a frame.
