Throwing dart

摘要

A throwing dart having a handle that provides a user with tactile biofeedback. The handle includes a handle body having an exterior body surface defined by a first octant, a second octant, a third octant, a fourth octant, a fifth octant, a sixth octant, a seventh octant, and an eighth octant. The handle includes at least a first tactile reference indentation, or projection, that extends longitudinally along the exterior body surface and is confined to a first tactile octant. The first tactile reference indentation, or projection, is formed with dimensions specifically tailored to harness the user's natural attributes of sensibility, proprioception, and neuromuscular memory to improve a user's accuracy.

主权项

1. A throwing dart comprising:
a tip; a flight; and a handle (100) between the tip and the flight, the handle (100) having a handle body (101) having a handle length (110), a proximal end (120), a distal end (130), and an exterior body surface (160), wherein the exterior body surface (160) is defined by a first octant (161), a second octant (162), a third octant (163), a fourth octant (164), a fifth octant (165), a sixth octant (166), a seventh octant (167), and an eighth octant (168); a first tactile reference indentation (200a) extending along the exterior body surface (160) and confined to a first tactile octant, wherein the first tactile octant is selected from the group consisting of the first octant (161), the second octant (162), the third octant (163), the fourth octant (164), the fifth octant (165), the sixth octant (166), the seventh octant (167), and the eighth octant (168), the first tactile reference indentation (200a) having a first tactile reference indentation length (210a), a first tactile reference indentation width (220a) of at least 2.0 millimeters and no greater than 5.0 millimeters, and a first tactile reference indentation depth (230a) of at least 0.5 millimeters, wherein the only palpable indicia within the first tactile octant is the first tactile reference indentation (200a), and wherein the first tactile reference indentation (200a) provides a user with tactile biofeedback by two-point discrimination when gripping the handle (100); and a second tactile reference indentation (200b) extending along the exterior body surface (160) and confined to a second tactile octant, wherein the second tactile octant is selected from the group consisting of the first octant (161), the second octant (162), the third octant (163), the fourth octant (164), the fifth octant (165), the sixth octant (166), the seventh octant (167), and the eighth octant (168) that does not include the first tactile reference indentation (200a), wherein the first tactile octant and the second tactile octant are not adjacent to one another, and the second tactile reference indentation (200b) having a second tactile reference indentation length (210b), a second tactile reference indentation width (220b) of at least 2.0 millimeters and no greater than 5.0 millimeters, and a second tactile reference indentation depth (230b) of at least 0.5 millimeters, and wherein the second tactile reference indentation (200b) provides the user with tactile biofeedback by two-point discrimination when gripping the handle (100).
