Description

Technical Field

[0001] The invention relates to the field of bouncing sports equipment, and particularly to a combined spring type bouncing assist shoe. Background Art

[0002] At present, bouncing shoes are mainly divided into two types with a spring as the elastic body and a leaf spring as the elastic body. The bouncing shoe with a leaf spring as the elastic body is imitated according to the legs of a kangaroo. During the repeated compression process of the leaf spring, irregular lateral swing will occur, and it is easy for the human body to fall and get injured laterally during the bouncing process. There are various types of bouncing shoes with a spring as the elastic body, but most of these bouncing shoes belong to the toy field and have poor bouncing performance.

[0003] For example, a Chinese patent discloses a bouncy stilts shoe, publication (announcement) number: CN212817933U. Its advantage is good stability, but it is targeted at children and has poor bouncing performance. Another bouncing shoe disclosed in a Chinese patent, publication (announcement) number: CN207269956U, has good bouncing performance and can be suitable for people with different foot sizes. However, the area of the protective pad in contact with the ground in this invention is relatively small, and it is easy for the human body to fall and get injured laterally during bouncing. Summary of the Invention

[0004] To solve the problems raised in the above background art, the purpose of the present invention is to provide a combined spring type bouncing assist shoe, which is convenient to operate and conforms to the advantage of the angle of the foot leaving the ground when a human body jumps.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A combined spring type bouncing assist shoe, including a combined spring structure, a foot pedal support structure, and an anti-slip rubber pad. The combined spring structure is installed in a spring barrel, fixedly connecting the foot pedal and the anti-slip rubber pad. A toe slot is installed at the front of the foot pedal, and a leg support frame is installed at the rear. An adjustable elastic band is installed on the leg support frame. The anti-slip rubber pad is designed according to the optimal angle between the take-off leg and the ground when a human body jumps and is fixed on the lower flange.

[0006] The combined spring structure is as follows: The combined spring is fixed on the upper flange, and a spring telescopic rod is sleeved inside. The spring telescopic rod and the large cylinder are fixed on the upper flange through a fixed shaft. The lower end of the combined spring is fixed to the lower flange, and the lower flange is fixed to the anti-slip rubber pad. Four sliding blocks are fixed on the outside of the small cylinder, and the sliding blocks slide in the large cylinder track.

[0007] The foot pedal support structure is as follows: The upper flange is fixed to the lower part of the foot pedal, the toe block is fixed to the front, the leg support frame is fixed to the rear, a leg elastic band is installed on the leg support frame, and the fixed end holders are fixed to both sides of the foot pedal, on which a foot elastic band is installed.

[0008] The anti-slip rubber pad has the following structure: The anti-slip rubber pad is fixed to the lower plate, with a front inclination angle of 75° and a rear inclination angle of 75°, and the bottom surface is designed with serrations.

[0009] Preferably, in the present invention, the major diameter ratio of the outer spring and the inner spring of the combined spring is 5:2.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The present invention adopts a combined spring design, with a compact structure and better jumping performance. The anti-slip rubber pad adopts an inclination design at the front and rear, which conforms to the take-off angle of the foot when a person jumps, has good stability, a toe slot at the front end, and an elastic band is installed on the leg support frame, making it convenient and firm to wear.

Detailed Embodiment

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] As Figures 1 to 4 shown, a combined spring type bouncing assist shoe provided by the present invention includes a combined spring structure, a pedal support structure, and an anti-slip rubber pad; the combined spring structure 1 is installed in the large cylinder 14, fixedly connecting the pedal 2 and the anti-slip rubber pad 4. A toe slot 5 is installed at the front of the pedal 2, and a leg support frame 6 is installed at the rear. The design of the anti-slip rubber pad 4 conforms to the take-off angle of the foot when a person jumps and is fixed through the lower flange 17 and the small cylinder 15.

[0016] The structure of the combined spring structure 1 is as follows: The combined spring 13 is fixed on the upper flange 9, and a spring telescopic rod 18 is sleeved inside. The spring telescopic rod 18 and the large cylinder 14 are fixed on the upper flange 9 through a fixed shaft 11. The lower end of the combined spring 13 is fixed to the lower flange 17, and the lower flange 17 is fixed to the anti-slip rubber pad 4. Four sliding blocks 16 are fixed on the outer side of the small cylinder 15, and the sliding blocks 16 slide in the track of the large cylinder 14.

[0017] The structure of the pedal support is as follows: The upper flange 9 is fixedly installed at the lower part of the bottom plate 2. The toe catch 5 is fixed at the front part of the bottom plate 2, and soft rubber is covered inside the toe catch 5. The leg support frame 6 is fixed at the rear part, and the leg elastic band 7 is installed on the leg support frame 6. The foot elastic bands 8 are installed on both sides of the bottom plate through the tape end fixers 10.

[0018] The structure of the anti-slip rubber pad 4 is as follows: The anti-slip rubber pad 4 is fixed on the lower plate 25, with a front inclination angle of 75° and a rear inclination angle of 75°, and the bottom surface is designed with serrations.

[0019] Reference Figure 2 , soft rubber is covered inside the toe slot 5, and soft rubber is covered inside the leg support frame 6.

[0020] As a technical optimization scheme of the present invention, covering with soft rubber makes it more comfortable when the human body jumps.

[0021] Reference Figure 3 , the sliding block 16 is fixed in the outer slot of the small cylinder 15 and slides in the inner track of the large cylinder 14.

[0022] As a technical optimization scheme of the present invention, by fixing the sliding block 16 in the outer slot of the small cylinder 15, the sliding gap between the large cylinder 14 and the small cylinder 15 is very small, avoiding small particulate matters such as sediment from entering during human movement.

[0023] The design principle of the anti-slip rubber pad of the present invention, reference Figure 4 , when the combined spring is in a compressed state, the connecting line between the front end of the anti-slip rubber pad and the front end of the pedal forms an angle of 75° with the horizontal plane. When the combined spring is in its original length, the connecting line between the rear end of the anti-slip rubber pad and the rear end of the pedal forms an angle of 75° with the horizontal plane, which conforms to the take-off and landing ground clearance angles of the human foot.

[0024] For the described embodiments of the present invention, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
