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.
- 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.
- FIG. 1 is a perspective view of the elastic structure of a sport equipment according to one embodiment of the present disclosure
- FIG. 2 is another perspective view of the elastic structure of FIG. 1 ;
- FIG. 3 is a schematic view showing a folded state of the elastic structure of FIG. 1 ;
- FIG. 4 is an enlarged view of a pivoting socket of a front section of the elastic structure
- FIG. 5 is a schematic view showing swinging of the pivoting socket of the front section of the elastic structure
- FIG. 6 is a schematic and enlarged view showing swinging of a rear section of the elastic structure
- FIG. 7 is a perspective view of the elastic structure of a sport equipment according to another embodiment of the present disclosure.
- FIG. 8 is another perspective view of the elastic structure of FIG. 7 ;
- FIG. 9 is a schematic view showing a folded state of the elastic structure of FIG. 7 ;
- FIG. 10 is a perspective view of the elastic structure of a sport equipment according to further another embodiment of the present disclosure.
- FIG. 11 is another perspective view of the elastic structure of FIGS. 10 ;
- FIG. 12 is an enlarged view of the elastic structure of the sport equipment according to still another embodiment of the present disclosure.
- 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 .

- Description of Related Art
- Recently, the technology of the foldable sport equipment has developed towards without electricity for easily using and operating. Therefore, 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.
- However, the longer extendable and retractable space and the foldable sport equipment are conflicted. Now, the elastic member normally uses a non-fixed elastic string for free the design space of the foldable sport equipment. For example, 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.
