  • Patent number: 8771156
    Abstract: An improved structure to fix an inflatable and elastic motion body includes an elastic air bag, a frame, a base and a plurality of restricting pieces. The base has a receiving slot recessedly formed close to a top surface of the base, and a recessed engaging trough recessedly formed close to a bottom surface thereof. The recessed engaging trough engages with a hook end of the restricting piece, so the restricting piece can tightly clamp a fixed edge of the elastic air bag. Since the restricting pieces with better strength are disposed in restricting slots of the frame to tightly confine the elastic air bag and the base to locate between the hook end and the pressing end of the restricting piece, so when the elastic air bag is heavily pressed, it would not escape from the restricting slot of the frame to increase the structural strength and durability.

  • Patent number: 7662072
    Abstract: An exercising device includes a control handle having a limit flange, a retaining ring mounted on the limit flange, a mounting seat combined with the retaining ring to limit the limit flange between the mounting seat and the retaining ring, a driven member mounted on the mounting seat, a stop member mounted on the driven member, and a weight member located between the mounting seat and the stop member. Thus, the weight member is adjustably mounted on the driven member to adjust the relative position between the weight member and the mounting seat and to adjust the damping force applied by the weight member onto a user's hand. In addition, the stop member can stop movement of the weight member to prevent the weight member from being detached from the driven member due to an excessive centrifugal force.
