Abstract:
1. A push-pull pin for securing items to a supporting material comprising: a handle; a pin having a deformed end embedded into the handle and a pointed end for piercing items to be supported to the supporting material; the handle consisting of six surfaces forming a three-dimensional polygon including four major surfaces and two minor surfaces, one of the minor surfaces is at the bottom of the handle and includes the pin protruding therefrom, the other minor surface is at the top of the handle and is parallel to the bottom minor surface, two of the major surfaces are diametrically opposed to one another and are symmetrically inclined away from one another from the top minor surface to the bottom minor surface to facilitate grasping and pushing forces for piercing the items and pushing the pin into the supporting material, the other two of the major surfaces are diametrically opposed to one another and are symmetrically inclined away from one another from the bottom minor surface to the top minor surface to facilitate grasping and pulling forces for pulling the pin from the support material and items.
