Abstract: A diving board stand comprising a fulcrum base, a fulcrum roller configured to be supported over the fulcrum base and movable on the fulcrum base, a rear anchor for connecting the diving board stand to a rear end of a diving board, and an alignment beam for connecting the fulcrum base to the rear anchor.

Abstract: A mobile exercise platform system having one or more top plates lengthwise oriented in a first longitudinal direction or a second longitudinal direction, and two or more spring bars directly fastened to the top plates and being lengthwise oriented in a transverse direction. A coupling mechanism joins two individual exercise platforms together to increase the modes of exercise that may be performed. Openings in the top plates and support rods fastened to the underside of top plates further increase the versatility of exercise modes.

Abstract: A foldable diving platform for attachment to a wakeboard tower. The platform includes a base section affixable to tubing of the wakeboard tower and a folding section hinged to the based section. The folding section may be rotated about the hinge to enable storage atop the base section or full deployment collinear and coplanar with the base section.

Abstract: A boat including a frame and a diving board mounted to the frame. The diving board includes a base and a board coupled to the base at a pivot location. The board extends from the pivot location to a distal end. An axial spring is interconnected between the base and the board for cancelling out forces which are imparted by a user jumping on the board at the distal end.

Abstract: A system for practicing striking is described. The system includes a base support member, a support arm hingedly connected to said base support member capable of swinging from a first, at-rest position, to a second, post-strike position, a striking surface attached to an end of said support arm, and a return mechanism configured to resiliently return said support arm from said post-strike position to said at-rest position after the striking surface has been struck. The striking surface comprises one or more walls capable of providing tactile feedback to a practitioner for practicing a striking technique.

Abstract: A floor system (20) includes a plurality of cushioning devices (22) attached to a lower side (40) of a wood floor (32). Each cushioning device (22) includes a spring (46) that may be attached at each of its ends to first and second caps (48, 50). The spring (46) includes longitudinally aligned regions (58, 60) interposed between the caps (48, 50). The region (58) exhibits a lower spring rate (64) than a spring rate (66) of the other region 60. In response to an imposed force, the first region (58) of spring (46) first compresses. When the imposed force is great enough, due to a user's weight, the second region (60) of spring (46) will then compress.

Abstract: A gymnastics springboard with adjustable elasticity comprising a top board coated with a coating subdivided into two distinct zones enabling the impact zone to be demarcated visually, which presents a homogeneous and flexible structure with a hardness able to be adjusted by means of: a curved intermediate plate articulated on the frame at its bottom end by a hinge and bearing by rolling means at its top end under the middle of the impact zone of the board, an adjustable support bar cooperating with the curved intermediate plate between two longitudinal positions by maneuvering actuating member, said bar being guided by rails in the hole of the frame, and a system for quick addition or removal of springs positioned underneath the frame by a combined compression and rotation movement through the oblong holes.

Abstract: A gymnastic apparatus for performing vaults possesses a lower portion, an upper part arranged on same in a vertically adjustable fashion and constituted by a board arranged in a resilient manner on the lower portion. A gymnast running toward a front side of the apparatus, places his hands on the top side of the board, which forms a support face, applies his weight for an instant and leaps over the apparatus. In such leap he is aided by the resilient board. A front region of the board rises from the front convexly toward the rear in a arcuate manner, the arcuate region merging with an approximately horizontal flat region. The transitional region and/or the flat region serves a support face.

Abstract: A diving board lift assembly for lifting a diving board from a substantially horizontal diving position to a substantially upright position is provided. The diving board having a diving end and a hinged end with the hinged end hingedly connected to a diving board support member. In accordance with the present invention, a lifting mechanism is provided to lift the diving end of the diving board to the substantially upright position.
