Elastomerically self-grasping spear holder for underwater sling

摘要

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.

主权项

1. A spear holder for a spear sling, comprising:
a front part being a ring and having a first diameter; a rear part being a solid cylinder having said first diameter; a center part between said front part and said rear part having a partial outer cylindrical surface formed of a plurality of support arms, said partial outer cylindrical surface having said first diameter; and a tube-shaped elastomeric constrictor extending over said support arms having sides spaced from each other by a dimension less than said diameter; wherein a spear having a second diameter less than side first diameter inserted between said sides of said elastomeric constrictor is gripped by a contraction of the elastomeric constrictor.
