Abstract: A way to attach a trampoline enclosure to a trampoline frame is described. This process involving constructing the enclosure with a buttonhole at or near its bottom edge. This buttonhole is designed to receive a spring attachment feature located on the rebounding mat of the trampoline structure. Generally, this spring attachment feature will be the D-ring (or V-ring) that is used to attach the rebounding mat to the springs. The D-ring will pass through the buttonhole and, when connected to a corresponding spring, will securely attach the trampoline enclosure to the trampoline.

Abstract: A loading device for an exercise machine includes a lever arm and a nitrogen gas compression spring in a force triangle that provides easy adjustment of the resistive load presented to a user. The nitrogen gas compression spring and the selected portion of the lever arm comprise two legs of the force triangle, with a slidable coupling selectively interconnecting the nitrogen gas compression spring with the lever arm at adjustment points on the lever arm. Both the nitrogen gas compression spring and the lever arm are pivotally mounted on a rigid member, with the distances between their pivots forming the third leg of the force triangle. The nitrogen gas compression spring exhibits a high resistance, a flat spring rate and is of rigid construction so that the lever arm and nitrogen gas compression spring are self-supported at all times.

Abstract: The shoe accessory includes a platform for supporting a conventional shoe. The shoe accessory's base has a convex or other non-planar surface that causes the shoe accessory to be stable in a longitudinal (heel-toe) direction, and unstable in a lateral (medial/lateral) direction. The non-planar surface may be defined by a ridge segment on the platform's bottom side. One or more straps are provided to temporarily secure the wearer's conventional shoe to the platform in a non-destructive manner. A generally U-shaped heel retainer may be provided adjacent a rear portion of the platform for receiving the heel of the shoe. The shoe accessory makes a flat-soled shoe laterally unstable while allowing for longitudinal stability and a naturalistic gait, and thus facilitates exercise of leg and foot muscles during normal walking, etc.

The magnetic element is mounted to the ring. The illumination control circuit board and the coil holder are received in a recess defined in one of the ends of the rotor. The coil holder forms a bore in which the magnetic element is received. The coil holder carries thereon at least one pair of coils. The illuminators are distributively arranged on an outer surface of the rotor and are electrically connected to the illumination control circuit board.

Abstract: An exercise machine has a main frame and a user support frame pivotally mounted relative to the main frame for rotation about a user support pivot axis between start and end positions. The user support frame has at least a primary support and a secondary support for supporting spaced positions on a user's body throughout an exercise movement. The user support pivot axis is spaced below at least one of the supports in at least one of the exercise start and end positions. A user engagement device is movably mounted relative to the frames for engagement by the user in performing exercises, and a multiple part connecting linkage translates movement of the user engagement device to rotational movement of the user support frame. A load resists movement of at least one of the user support, user engagement device, and connecting linkage.

Abstract: An exercise apparatus includes a frame and handles mounted on the frame and moveable by a user in opposite directions. The handles are coupled to a transmission so that movement of the handles by a user create rotational movement of a transmission input, movement of the handles in one direction creating rotational movement of the transmission input in one direction and movement of the handles in the opposite direction creating rotational movement of the transmission input in the opposite direction. The transmission couples the transmission input to a resistance means, such as an eddy current resistance device, in a manner to provide a different resistance to rotation of the transmission input depending upon the direction of rotation of the transmission input. Thus, the resistance to rotational movement of the transmission input in one rotational direction is greater than it is in the opposite rotational direction.

Abstract: A collapsible resistance exercise device for compact storage and quick deployment includes a horizontally disposed base support frame and an upright frame pivotally attached to the base frame. The upright frame includes a resistance bar pivotally mounted thereon. In practice, the device is placed on a level surface with the base support frame resting on the surface. The free end of the upright frame is rotated upwardly to a vertical position where it is releasably locked into position to be free standing. One end of a pair of springs are attached to spring attachment loops disposed on the upright frame. The opposing ends of the springs are attached to spring attachment loops disposed on a resistance bar, strap or similar device. The exercisor exercises a muscle group by contacting a limb with the resistance bar and repetitively moving the resistance bar against the restoring force of the springs.
