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 foot support surface on which a user can directly place 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 the high rebound platform, in said compressed state said foot support surface is positioned closer to said impact surface without significant plastic deformation of the high rebound platform, so that when a compressive force is applied to 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 back to its uncompressed state from its compressed state;said foam material comprises a plurality of substantially planar layers of foam laminated to one another, said impact surface being a generally flat surface;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; anda handle located on the tether.
