Title: Pre-curved gunn cut gloves
Inventor: GOLD DANNY
IPC: A41D19/02
Filed: 2003-02-03
Abstract: A gunn cut glove construction in which a pre~curvature at selected locations, preferably around the joints, in the fingers is achieved by sewing wedges of material into cut portions of the gunn section so that the shortened fingers and larger back sections easily meet at and can be joined without the need to gather or moccasin material resulting in the shape of the finger being such that it curves forward towards the palm section. Increased volume at the fingertips of a gunn cut construction glove is achieved by darting the palm side pieces of fingers proximate the fingertips. In addition, to reduce the inflexibility of gloves when curled into a fist, an elliptical piece is removed from the palm portion of the glove and the sides of the elliptical piece are sewn together along a seam. The seam is windowed by a guard piece affixed to the palm portion of the glove which is cut out in an area directly over and around the seam and preferably in the area where the user's hand normally bends as the fingers and hand are curled inwardly into a fist shape.  The windowed seam enhances the flexibility of the glove. In addition, by increasing the length of the palm portion of the fingers so that the palm portion wraps over the top of the fingertips and joins the back portion of the fingers a distance from the fingertips, wear on the seam is reduced significantly and enhanced sensitivity at the fingertips is achieved.
