Abstract: An inflatable mat for use as a training aid and supporting and rebound surface, such as for a gymnastics mat, and fall breaking landing pad, such as for a high jump and pole vaulting landing pit, includes a closed inflatable body having opposite sides and a plurality of bungee cords secured to and extending between the opposite sides whereby, when the body is inflated, a force applied to the mat, such as by an athlete jumping on the mat or falling onto the mat, will cause stretching of at least one of the bungee cords to aid in absorbing the force applied to the mat. With a closed or sealed inflatable body, the mat can be adjusted by adjusting the amount of inflation to provide shock absorption and rebound when jumping on the mat similar to a trampoline surface or to provide more deceleration and absorption of a fall onto the mat and less rebound as needed for landing pit applications.

Abstract: The riding trainer structure includes a foundation, a drive motor, a first drive gear, a vertical rocker, a swinging seat frame, a second drive gear and a vertical guide set. The first drive gear is screwed onto the standing support, and a first drive wheel is eccentrically arranged at one side of the first drive gear. The bottom of the vertical rocker is screwed onto the foundation for horizontal swinging. A limit guide portion is placed at one side of the vertical rocker. The second drive gear driven by the first drive gear can rotate synchronously, and an eccentric second drive wheel of the second drive gear drives the vertical guide set, enabling the top of latch rod to drive the swinging seat frame vertically. The swinging amplitude of the vertical rocker could be changed to achieve better swinging strength and stability.

Abstract: A frame for use with a removable switch-carrying platform during machine dance activity. The frame includes a horizontal member that serves as an anchor, and typically is disposed below the platform. An upstanding member, typically cantilevered from the anchor, may be provided to hold a trickbar, or a video display device. Sometimes, two upstanding members are provided, each at opposite front and rear ends of an installed platform, to hold a trickbar and a display device, respectively. The frame may be configured to accommodate either a single-user or dual-users. In a preferred arrangement, the frame is modular, to permit a user to form: 1) only a trickbar, 2) a trickbar in combination with a display holder, and 3) a dual-user platform. A modular dual-user platform may include a trickbar for either, both, or none of the dance platforms, as desired.

Abstract: The abdominal exerciser of the present invention is an exercise device designed to work the abdominal and oblique muscle groups.

Abstract: A safety locking system is used on an exercise device. The locking system includes a first pawl that is mounted to a pawl shaft. The pawl shaft is movably mounted to a lock frame, which can also support a weight collar, adapted to receive weight plates to provide additional resistance to exercise. A second pawl is movably mounted to the lock frame and is connected to the first pawl by way of a spring or other bias mechanism. The lock frame limits the movement of the second pawl so as to provide a bias of the first pawl toward engagement of the pawl to a rack provided with the exercise device. The engagement of either pawl with the rack restricts movement of the lock frame in at least one direction, with gravity. If the bias spring breaks or becomes disengaged from either the first pawl or the second pawl, the second pawl is counterweighted to engage with the rack.
