Abstract:
A jump skate for permitting a skater to perform jumping maneuvers, comprising:a boot; a surface engager having a ground traversing lower portion; a forward link and a rearward link, the forward link having an upper end portion pivotally connected at a forward portion of the bottom of the boot at a first pivot connection, and a lower end portion pivotally connected at a forward portion of the surface engager at a second pivot connection, and the rearward link having an upper end portion pivotally connected at a rearward portion of the bottom of the boot at a third pivot connection, and a lower end portion pivotally connected at a rearward portion of the surface engager at a fourth pivot connection; and a wound spring operationally attached at at least one of the first through fourth pivot connections so as to bias the boot in a direction away from the surface engager by virtue of a torque exerted by the wound spring, the wound spring having a characteristic of quick storage/release of energy through a torque-wise deformation/recovery thereof, to assist a jump.
