Abstract:
A jumping device by which a user can jump on the ground repeatedly by interaction between at least a hand and a foot of the user, the jumping device comprising:a high rebound platform comprising a foam material, the high rebound platform formed to provide a generally flat foot support on a compliant foot support surface on which a user can directly place a portion of a foot and an impact surface for engaging and moving away from the ground during jumping, said high rebound platform being able to assume a compressed state from an uncompressed state when a compressive force is applied to said compliant foot support surface of the high rebound platform, in said compressed state a portion of said compliant foot support surface is positioned closer to said impact surface without significant plastic deformation of the high rebound platform, so that when the compressive force is applied to said compliant foot support surface of said high rebound platform said high rebound platform is changed from its uncompressed state to its compressed state with energy absorbed thereby and which energy is utilized to assist a user in jumping as the high rebound platform changes from its compressed state toward its uncompressed state; a flexible tether operatively connected at a first end thereof to the high rebound platform so that the tether is movable with the high rebound platform during jumping; and a handle located on the tether.
