Abstract
An ice axe device comprising a handle having a gripping end and a working end and an impact member attached at the working end. The gripping end is configured about its longitudinal axis with a smaller, forward curvature and a larger, rearward curvature. The smaller, forward curvature is approximately defined by a radius slightly smaller than a corresponding radius of an arc formed at an inner surface of the user's fingers when wrapped about that portion of the gripping end. The larger, rearward curvature is approximately defined by a larger radius which is slightly smaller than a corresponding radius of an arc formed by a users palm and a proximate inside portion of an extending thumb when wrapped around the gripping end.
Claims22
An ice axe device comprising:
- a handle having a gripping end and a working end;
- an impact member attached at the working end of the handle and configured for use as an ice axe;
- said gripping end of the handle being configured about a longitudinal axis with a relatively smaller, forward curvature as compared to a relatively larger, rearward curvature, and wherein the forward curvature and the rearward curvature are separated by lateral, generally parallel sides said, sides forming concave junctions with said larger, rearward curvature;
- said smaller, forward curvature being approximately defined by a radius slightly smaller than a corresponding radius of an arc formed at an inner surface of a user's fingers wrapped around a forward portion of the gripping end of the handle;
- said larger, rearward curvature being approximately defined by a larger radius slightly smaller than a corresponding radius of an arc formed by the user's palm and approximate inside portion of an extending thumb wrapped around a rearward portion of the gripping end of the handle.
A grip device used with an axe handle, said grip device comprising:
- a sleeve member configured to fit snugly around a gripping end of the axe handle, said sleeve member being configured about a longitudinal axis with an exterior surface having a smaller, forward curvature and a larger, rearward curvature wherein the smaller, forward curvature is separated from the larger, rearward curvature by generally straight and parallel extending lateral sides, each of said sides forming a generally concave junction with said larger, rearward curvature,
- said smaller, forward curvature being approximately defined by a radius slightly smaller than a corresponding radius of an arc formed at an inner surface of a user's fingers wrapped around a forward portion of the gripping end of the handle;
- said larger, rearward curvature being approximately defined by a larger radius slightly smaller than a corresponding radius of an arc formed by a user's palm and a proximate inside portion of an extending thumb wrapped around a rearward portion of the gripping end of the handle, said forward curvature comprising a radius corresponding to a radius of an arc formed by a user's fingers wrapped around a forward portion of the gripping end of the handle.
