ABSTRACT:
A vaulting device for use by a gymnast in vaulting comprising a top member connected to a base member, via a rigid control member and a movable pivot, with a plurality of resilient members positioned between the base member and the top member to bias the base member away from the top member. When the top member is compressed toward the base member, the control arm and the movable pivot combine with one another to cause the top member to move longitudinally relative to the base member during compression and expansion strokes of the vaulting device.
