The present invention relates to an improved structure to fix an inflatable elastic motion body, and more particularly to restricting pieces with better strength disposed in the restricting slots of the frame to tightly clamp and 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.
A conventional structure to fix an inflatable elastic motion body as shown in
The problems the present invention wants to solve are (a) when the conventional inflatable elastic motion body is used, it bears great deal amount of pressure from a user, so the ring frame made by plastic materials is easily to be bended or deformed, and the main body cannot be securely fixed to the base unit; and (b) the base unit are usually made by several boards connected with each other, but the structural strength is usually not strong enough, and it will adversely affect the durability of the entire structure for the inflatable elastic motion body.
To solve and overcome the problems stated above, the present invention provides 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 elastic air bag is a semicircular ball-shaped body, and a fixed edge is protrudingly formed at a lower periphery of the elastic air bag, and a connecting edge extends downwards from the fixed edge. The frame is ring-shaped frame, and a restricting slot is recessedly formed at an inner portion thereof to provide a space for the fixed edge of the elastic air bag. The base includes a receiving slot recessedly formed close to a top surface of the base, and a recessed engaging trough is recessedly formed close to a bottom surface of the base. The restricting piece is made by metal materials with better strength, and is spacedly disposed at an edge of the base to evenly distribute the tension. A hook end is bending and extending from one end of the restricting piece, and the hook end engages in the recessed engaging trough of the base. A pressing end is bending and extending from the other end of the restricting piece to tightly clamp the fixed edge of the elastic air bag. Accordingly, an improved structure to fix an inflatable and elastic motion body is obtained.
Comparing with the conventional arts, the present invention provides an improved structure to fix an inflatable and elastic motion body having the restricting pieces with better strength are disposed in the restricting slots of the frame to tightly clamp and 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 thereof. Furthermore, the restricting pieces of the improved structure are positioned corresponding to the gaps between each fan-shaped board, so the structural strength of the fan-shaped board and the base is enhanced.

Referring to
Referring to
According to the embodiments discussed above, the present invention is advantageous because (a) the restricting pieces (40) with better strength are disposed in the restricting slots (211) of the frame (20) to tightly clamp and confine the elastic air bag (10) and the base (30) to locate between the hook end (41) and the pressing end (42) of the restricting piece (40), so when the elastic air bag (10) is heavily pressed, it would not escape from the restricting slot (211) of the frame (20) to increase the structural strength and durability thereof; and (b) the restricting pieces (40) are positioned corresponding to the gaps (311) between each fan-shaped board (31), so the structural strength of the fan-shaped board (31) and the base (30) is enhanced.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalent.
