Abstract
A ball is provided for use in training that collapses when hit or kicked and then resiliently reforms itself to its original shape, dissipating kinetic energy and allowing use of the ball in a restricted geographical area. In one aspect, the ball of the invention includes incisions extending substantially through a shell, which deform upon striking, such that the ball and collapses venting air and dissipating kinetic energy. In another aspect, the ball of the present invention includes incisions extending only partially through the outer shell, contributing to the deforming properties of the ball when struck.
Claims6
A ball for simulating the performance of a regulation size sport ball, comprising:
- a shell having an outer surface and an inner surface defining a fluid-filled interior;
- and
- at least one incision extending substantially through said outer surface and said inner surface of said shell, said incision having a first side and a second side;
- wherein the first and second side of the incision are substantially juxtaposed in a substantially sealing engagement when the ball is in a resting position.
