Definitions
- the present disclosure relates to a foldable sport equipment. More particularly, the present disclosure relates to an elastic structure of a sport equipment that supplies an ample and effective recovering force.
- an elastic member is the most important parts of the foldable sport equipment, and the elastic member of the foldable sport equipment needs a longer extendable and retractable space for moving.
- the elastic member normally uses a non-fixed elastic string for free the design space of the foldable sport equipment.
- the non-fixed elastic string is detachably located at an end of the foldable sport equipment, and a handle is connected to the non-fixed elastic string for generating a reciprocate stretching movement. Therefore, the conflict between the longer extendable and retractable space and the foldable sport equipment puzzles the designer of the foldable sport equipment.
- the non-fixed elastic string occupies space and interferences folding action, and the non-fixed elastic string will bounce or shake during a user operation. The bouncing or shaking is very dangerous if the user performs a wrong operation.
- an elastic structure of a sport equipment comprises a base, a staggered frame, an elastic body and an applying member.
- the base is supported on a ground.
- the staggered frame has a front section, a middle section and a rear section.
- the middle section has a pivoting portion that is pivoted at the base, thus the front section and the rear section are extending outward from the pivoting portion, and the front section has an extending socket, and the rear section has a positioning socket.
- the elastic body is extendably and retractably located on the extending socket and the positioning socket.
- the applying member is connected to the elastic body for generating a stretching movement back and forth.
- the pivoting portion of the middle section has a pivoting rod, and the staggered frame is staggered at an angle with the base to form an X-shape via the pivoting rod. Therefore, the angle between the staggered frame and the base can be adjusted via the pivoting rod.
- the elastic structure of the sport equipment has two elastic bodies and two applying members.
- the first pivoting socket includes a first pulley.
- the first pulley is pivoted at the first pivoting socket, and each of the two elastic bodies is arranged through the first pulley.
- One end of the elastic body is located at a first pin.
- the end of the elastic body extends from the first pivoting socket, and the first pivoting socket has a first connector connected to the end of the elastic body.
- the first connector is detachably connected to the applying member.
- the first pin is located between the first pivoting socket and the first connector. The first pin is for connecting the first connector to the elastic body, thus a detachment of the elastic body from the first pivoting socket can be avoided by the first pin.
- an elastic structure of a sport equipment comprises a base, a staggered frame, an elastic body and an applying member.
- the base is supported on a ground.
- the staggered frame has a front section, a middle section and a rear section.
- the middle section has a pivoting portion that is pivoted at the base, thus the staggered frame is staggered at an angle with the base to form an X-shape, and the pivoting portion that is connected to the base can adjust the angle rotatably.
- the front section and the rear section are extending outward from the pivoting portion.
- the front section has an extending socket, and the rear section has a positioning socket.
- the elastic body is passed through the extending socket and the positioning socket, and the elastic body is extendably and retractably located on the extending socket and the positioning socket.
- the applying member is connected to an end of the elastic body for generating a stretching movement back and forth.
- the end of the elastic body can be directly linked and connected to the positioning socket.
- the end of the elastic body can extend in a reverse direction via the positioning socket, and the another end is connected to the applying member respectively.
- the Fig. 1 is a perspective view of the elastic structure of a sport equipment according to one embodiment of the present disclosure.
- the Fig. 2 is another perspective view of the elastic structure of Fig. 1 .
- the Fig. 3 is a schematic view showing a folded state of the elastic structure of Fig. 1 .
- the elastic structure of the sport equipment comprises a base 100, a staggered frame 200, two elastic bodies 300 and two applying members 400.
- the base 100 is supported on a ground.
- Each of the two elastic bodies 300 is extendably and retractably located on an extending socket 221 and a positioning socket 231.
- Each of the two applying members 400 is connected to one of the two elastic bodies 300, and the applying member 400 can stretch reciprocately via an elastic recovering force of the elastic body 300.
- the staggered frame 200 has a front section 220, a middle section 210 and a rear section 230.
