US Patent:
4256244, Mar 17, 1981
Filed:
May 9, 1980
Appl. No.:
6/148149
Inventors:
Ronald S. Gasper - Alexandria VA
International Classification:
A41F 900
US Classification:
224252
Abstract:
A ball holder comprising a single resilient ring having an internal diameter slightly less than the external diameter of the ball to be held and a clip means comprising a pair of substantially U-shaped members integrally joined at their top extremities to form a clip for engaging a planar substrate, said ring being attached to a center portion of the base of one of said substantially U-shaped members in a manner whereby said ring diverges outwardly from the point of attachment, the plane of said ring forming an acute angle with the plane of said substantially U-shaped member so as to permit insertion of a ball between said ring and said U-shaped member and to provide flexure of the ring away from said U-shaped member when a ball is inserted, the flexure of said ring providing sufficient biasing force to hold the ball between said ring and said U-shaped member.
