Abstract

An adaptive checker piece for facilitating gripping and manipulation of the checker piece comprising a round main body and a gripping leaf extending therefrom. The gripping leaf forms a segment of a cone spanning an angular range α, and the gripping leaf is angled outwardly relative to a central axis of the main body at an angle β. A round upper platform projects concentrically from the main body but with a smaller diameter whereby an upper raceway is formed. The gripping leaf projects from the main body from a position laterally outward of the upper raceway. A lower toroid projects concentrically from a lower portion of the main body and is sized to receive an upper platform of a second adaptive checker piece in an interference fit. Multiple checker pieces can be stacked to make king pieces and for storage despite the presence of the gripping leaf.

Dependent claims

An adaptive checker piece for facilitating gripping and manipulation of the checker piece, the checker piece comprising:

a main body with an upper portion, a lower portion, and a peripheral edge between the upper and lower portions of the main body;
one gripping leaf consisting essentially of a wall, wherein the gripping leaf has a proximal portion fixed to the main body and a distal portion that extends from the main body;
an upper platform that projects from the upper portion of the main body, wherein the upper platform is narrower in lateral dimension than the main body whereby an upper raceway is formed by a surface of the upper portion that projects laterally beyond the upper platform;
wherein the one gripping leaf projects from the main body laterally outwardly of the upper raceway formed by the surface of the upper portion that projects laterally beyond the upper platform and wherein the proximal portion of the one gripping leaf is disposed laterally outward of the upper raceway formed by the surface of the upper portion that projects laterally beyond the upper platform;
whereby the adaptive checker piece can be gripped, lifted, and moved by a gripping of the gripping leaf.
