Description

BACKGROUND

Technical Field

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.

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.

DETAILED DESCRIPTION

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. In 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. The middle section 210 has a pivoting portion 211, and the pivoting portion 211 of the middle section 210 has an open space 213, and the two elastic bodies 300 pass through the open space 213. The pivoting portion 211 is pivoted at the base 100, thus the front section 220 and the rear section 230 extend outward from the pivoting portion 211 and the base 100. The front section 220 has the extending socket 221, and the rear section 230 has the positioning socket 231.
In Fig. 3, the pivoting portion 211 of the middle section 210 has a pivoting rod 212, and the staggered frame 200 is staggered at an angle with the base 100 to form an X-shape via the pivoting rod 212. Therefore, the angle between the staggered frame 200 and the base 100 can be adjusted via the pivoting rod 212. When the base 100 and the staggered frame 200 are folded parallel to each other, the elastic structure of the sport equipment can have a smaller volume for collecting and saving.
Fig. 5 is a schematic view showing swinging of a first pivoting socket 500 of the front section 220 of the elastic structure. In Fig. 1 and Fig. 5, the elastic body 300 is located between the extending socket 221 and the applying member 400 along a moving direction, and the front section 220 has a first pivoting socket 500. The first pivoting socket 500 is pivoted at the front section 220, and a swing direction of the first pivoting socket 500 is corresponding to the moving direction. Therefore, the user can conveniently change his moving direction via the first pivoting socket 500.
Fig. 4 is an enlarged view of the first pivoting socket 500 of the front section 220 of the elastic structure. The first pivoting socket 500 includes a first pulley 510. The first pulley 510 is pivoted at the first pivoting socket 500, and each of the two elastic bodies 300 is arranged through the first pulley 510. One end of the elastic body 300 is located at a first pin 520.
The end of the elastic body 300 extends from the first pivoting socket 500, and the first pivoting socket 500 has a first connector 530 connected to the end of the elastic body 300. The first connector 530 is detachably connected to the applying member 400. The first pin 520 is located between the first pivoting socket 500 and the first connector 530. The first pin 520 is for connecting the first connector 530 to the elastic body 300, thus a detachment of the elastic body 300 from the first pivoting socket 500 can be avoided by the first pin 520.
Fig. 6 is a schematic and enlarged view showing swinging of the rear section 230 of the elastic structure. In Fig. 1 and Fig. 6, each of the two elastic bodies 300 is located between the positioning socket 231 and the applying member 400 along a moving direction. The rear section 230 has a second pivoting socket 600, and the second pivoting socket 600 is pivoted at the rear section 230. Each of the two elastic bodies 300 is passed through the second pivoting socket 600. A swing direction of the second pivoting socket 600 is corresponding to the moving direction. The second pivoting socket 600 comprises a second pulley 610. The second pulley 610 is pivoted at the second pivoting socket 600, and each of the two elastic bodies 300 is arranged through the second pulley 610.
Another end of the elastic body 300 extends from the second pivoting socket 600, and the second pivoting socket 600 has a second connector 630 connected to the another end of the elastic body 300. The second connector 630 is detachably connected to the applying member 400. A second pin 620 is located between the second pivoting socket 600 and the second connector 630. The second pin 620 is for connecting the second connector 630 to the elastic body 300, thus a detachment of the elastic body 300 from the second pivoting socket 600 can be avoided by the second pin 620.
Fig. 7 is a perspective view of the elastic structure according to an another embodiment of the present disclosure, and Fig. 8 is another perspective view of the elastic structure of Fig. 7, and Fig. 9 is a schematic view showing a folded state of the elastic structure of Fig. 7. The elastic structure of the sport equipment includes a base 100, a staggered frame 200, two elastic bodies 300 and two applying members 400. The base 100 is supported on a ground.
The base 100, the staggered frame 200 and the two applying members 400 have similar structures to those in the aforementioned embodiments. The staggered frame 200 also has a front section 220, a middle section 210 and a rear section 230. Similarly, each of the two elastic bodies 300 is extendably and retractably located on an extending socket 221 and a positioning socket 231. The difference of this embodiment is that the another end of each of the two elastic bodies 300, on the base 100, extends in a reverse direction via the positioning socket 231, and the two another ends are connected to the two applying members 400 respectively. Therefore, the elastic body 300 has more length extending space for a strong extendable and retractable operation. A folded form of the elastic structure of this embodiment is similar to that of Fig. 9.
In Fig. 10 or Fig. 11 is a further another embodiment of the present disclosure, the staggered frame 200 utilizes only one rod. The shape of the rod is rectangular, and the center of the staggered frame 200 has a hole (not numbered). The base 100 is passed through the hole.
In Fig. 12, the end of the elastic body 300 is directly linked and connected to the positioning socket 231 A. The elastic body 300 doesn't change its direction by a pulley, thus a simpler structure can be achieved.
According to the aforementioned embodiments and examples, the advantages of the present disclosure are described as follows. 1. The staggered frame is staggered at an angle with the base to form an X-shape via the pivoting rod. The base and the staggered frame can be folded, thus the elastic structure of the sport equipment has a smaller volume for collecting and saving. 2. The elastic body has more length extending space to a strong extendable and retractable operation. 3. The pivoting portion of the middle section has an open space, and the two elastic bodies pass through the open space. The base, the two elastic bodies and the staggered frame can be folded conveniently and more length housing space can be obtained.
Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims.
