Abstract

Abstract A device for deflecting a resilient ball in an unpredictable manner as an aid in developing speed, coordination, and timing on the part of the person causing the ball to come in forcible contact with the device. The device includes a horizontally disposed base from which project a plurality of hemispheric ball deflecting elements. The distance between such elements is such to cause a ball, when forcibly received thereagainst, to contact at least a portion of one of the elements thereby causing the elastic bouncing of the ball off the elements in an unpredictable manner.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 163 words
A game apparatus for deflecting a resilient ball in an unpredictable manner comprising: a body member having a horizontally disposed base and a flat upper surface; a tether member attached between said upper surface of said body member and said ball to provide limited movement of said ball relative to said body member; a plurality of hemispheric ball-deflecting means projecting from said flat upper surface and arranged in an ordered pattern, the outer surface of each of said deflecting means providing bounce-producing surface means; said deflecting means, each being symetrical about a vertical axis and being positioned a distance relative to each other sufficient to cause the surface of said ball when forcibly received against said upper surface to contact at least a portion of one of said bounce-producing surfaces rather than contacting only a flat portion of said upper surface, thereby causing the elastic bouncing of said resilient ball off said bounce-producing surface in an unpredictable manner the length of the tether.
Claim 2
Dependent Claim 163 words
A game apparatus for deflecting a resilient ball in an unpredictable manner comprising: a body member having a horizontally disposed base and a flat upper surface; a tether member attached between said upper surface of said body member and said ball to provide limited movement of said ball relative to said body member; a plurality of hemispheric ball-deflecting means projecting from said flat upper surface and arranged in an ordered pattern, the outer surface of each of said deflecting means providing bounce-producing surface means; said deflecting means, each being symetrical about a vertical axis and being positioned a distance relative to each other sufficient to cause the surface of said ball when forcibly received against said upper surface to contact at least a portion of one of said bounce-producing surfaces rather than contacting only a flat portion of said upper surface, thereby causing the elastic bouncing of said resilient ball off said bounce-producing surface in an unpredictable manner the length of the tether.
Claim 3
Dependent Claim 37 words
The game apparatus of claim 1 wherein said body member is circular and has a diameter of between 30 inches - 42 inches and said hemispheric ball-deflecting means are spaced on 1.5 inches - 2 inches centers.
Claim 4
Dependent Claim 33 words
The game apparatus of claim 2 wherein said ball has a diameter between 2 inches and 2.25 inches and said hemispheric ball-deflecting means have a diameter of between 1.25 inches to 1.5 inches.
