Abstract
Description
Technical Field
[0001] This application relates to the field of wearable equipment technology, and in particular to a jumping shoe. Background Technology
[0002] Jumping shoes are a type of sports equipment that combines the principles of ergonomics and bionics. They provide assistance through springs or elastic materials to achieve high-intensity jumps and dynamic movements. In addition to traditional sports training, jumping shoes have permeated the fields of daily commuting, outdoor adventure and fashion.
[0003] One type of jumping shoe has a sole composed of two arc-shaped spring supports combined to form an elliptical support base. The elasticity of the tension spring located between the two spring supports can be adjusted according to the wearer's weight. The jumping is achieved by utilizing the deformation of the spring supports and the tension recovery of the tension spring. The arc-shaped bottom of this jumping shoe makes contact with the ground, providing a larger contact area, making it easier for the wearer to control and adapting to more venues.
[0004] However, due to the limitations of its structure and movement, the existing jumping shoes have a one-piece rigid sole. When walking normally without jumping, the foot is restricted as a whole, and it is not possible to bend the forefoot and step on the ground while lifting the heel as in normal walking. Therefore, it is difficult to walk with alternating ground contact in existing jumping shoes. Because the foot is restricted as a whole, the straddle step cannot bend normally according to physiological characteristics, and the walking movement is stiff, which is not conducive to long-term wear. Utility Model Content
[0005] Therefore, the purpose of this invention is to overcome the shortcomings of existing bouncy shoes, which cannot achieve the same forefoot bending and heel lifting as in normal walking, resulting in stiff walking, and to provide a bouncy shoe. This invention conforms to ergonomic design, fits the foot better during normal walking, facilitates walking and control, and can be worn normally even when not for bouncy play, allowing for long-term wear and improving both the wearing and play experience.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A bouncy shoe includes a shoe body, and a support plate and a first folding elastic element respectively connected to the front and rear of the bottom of the shoe body. The support plate and the first folding elastic element are rotatably connected, and the connection point between the support plate and the first folding elastic element is located at the junction of the forefoot and the arch of the shoe body. The first folding elastic element includes an integrally formed top layer, middle layer and bottom layer. A second folding elastic element is connected between the support plate and the bottom layer of the first folding elastic element, and a third folding elastic element is connected between the top layer and the middle layer of the first folding elastic element.
[0008] This invention uses a first folding elastic element as an elastic support element to realize the bouncing and jumping functions of the bouncy shoe. In order to meet the changes of the human foot when walking, the junction of the forefoot and the arch of the shoe body is used as a rotating connection point to transfer the support plate and the first folding elastic element. In this way, when a person walks forward, the forefoot folds relative to the arch of the foot, and the support plate connected to the forefoot part of the shoe body can fold with the forefoot. This conforms to the ergonomic design, fits the foot better during normal walking, and is easier to walk and control. It can also be used for normal walking when not bouncing, can be worn for a long time, and has low requirements for the venue, thus improving the wearing experience and entertainment experience of this invention. In addition, the second folding elastic element provides better support for the support plate in the forefoot area, so that the forefoot is less likely to fall forward when standing normally, further improving the overall stability; the third folding elastic element forms support inside the structure of the first folding elastic element, providing better support for the arch and heel of the shoe, while improving the elasticity and support of the first folding elastic element. The second and third folding elastic elements together improve the jumping power and stability of the jumping shoe.
[0009] Furthermore, the number of the first folding elastic elements is two sets, with the two sets of the first folding elastic elements arranged side by side on both sides of the bottom of the shoe body, and a straight connecting rib and / or an X-shaped connecting rib provided between the two sets of the first folding elastic elements; the number of the second folding elastic elements and the third folding elastic elements is also two sets.
[0010] Designing two sets of first folding elastic elements side-by-side reduces their overall width and weight, making the entire jumping shoe lighter, easier to wear, and improving jumping performance. A straight or X-shaped connecting rib forms a stable connection between the two first folding elastic elements, allowing them to better transmit compressive force and deformation during jumping, resulting in better integration and jumping stability.
[0011] Furthermore, there may be multiple sets of the second and third folding elastic elements.
[0012] Furthermore, the support plate and the first folding elastic element are rotatably connected by a torsion spring or a hinge.
[0013] Furthermore, the length of the support plate is greater than or equal to the length of the forefoot portion of the shoe body, and less than or equal to the total length of the forefoot and toe portions of the shoe body; the bottom layer length of the first folding elastic element is greater than or equal to the overall length of the bottom of the shoe body. The support plate is mainly used to bear the pressure of the forefoot. The length of the support plate cannot be too small, otherwise the wearer will lack stability when standing. Through continuous testing and experimentation, when its length is controlled to be greater than or equal to the length of the forefoot portion of the shoe body, and less than or equal to the total length of the forefoot and toe portions of the shoe body, it provides a better wearing experience and usage effect.
[0014] Furthermore, both ends of the bottom layer of the first folding elastic element are provided with arc-shaped transition sections. Since the forefoot and heel both rotate with the ground when the wearer walks normally, the arc-shaped transition sections can better facilitate the switching of the foot during walking.
[0015] Furthermore, the bouncy shoe also includes a cushioning pad disposed on the bottom layer of the first folding elastic member.
[0016] Furthermore, the bottom of the cushioning pad is provided with several anti-slip grooves.
[0017] It should be noted that, in order to improve the user experience, a cushioning pad is designed at the bottom of the first folding elastic element. On the one hand, this reduces the impact force during the bounce, reduces vibration, and improves the wearing experience; on the other hand, adding a cushioning pad can reduce the wear of the first folding elastic element and increase its service life; at the same time, the addition of a cushioning pad can also make this utility model of the jumping shoe adaptable to more ground conditions and improve its adaptability to different usage scenarios.
[0018] Furthermore, the jumping shoe also includes a first balancing slider disposed between the top and middle layers of the two first folding elastic elements, and / or a second balancing slider disposed between the middle and bottom layers; the first balancing slider includes two first connecting rods rotatably connected at the center, one end of the two first connecting rods being hinged to the middle and top layers of one of the first folding elastic elements, and the other end of the two first connecting rods being slidably connected to the middle and top layers of the other first folding elastic element; the second balancing slider includes two second connecting rods rotatably connected at the center, one end of the two second connecting rods being hinged to the middle and bottom layers of one of the first folding elastic elements, and the other end of the two second connecting rods being slidably connected to the middle and bottom layers of the other first folding elastic element.
[0019] Furthermore, the surfaces of the middle and top layers of one of the first folding elastic members are provided with a first slide rail for sliding connection of the other ends of the two first connecting rods; the surfaces of the middle and bottom layers of the other first folding elastic member are provided with a second slide rail for sliding connection of the other ends of the two second connecting rods.
[0020] The two first connecting rods and / or second connecting rods are rotatably connected together in the middle to form an X-shaped intersection. When the first folding elastic element is compressed and deformed, the shoe body will expand and contract in a balanced manner regardless of which side of the two first folding elastic elements is subjected to force, after adjustment by the X-shaped element. The purpose of setting this balancing sliding element is to solve the problem of uneven force distribution in various parts of the shoe body.
[0021] As a preferred embodiment, the outer side of the first folding elastic element is covered with a rubber layer. The outer surface of the first folding elastic element is wrapped with a thin layer of rubber for protection.
[0022] As another preferred embodiment, the jumping shoe also includes a telescopic sleeve covering the support plate and the first folding elastic element.
[0023] Furthermore, the bottom of the shoe body has several through holes that connect to the telescopic sleeve.
[0024] Furthermore, the bottom of the shoe body has several through holes communicating with the telescopic sleeve. If a telescopic sleeve is used, the question of where the air inside the shoe should be expelled when the wearer is running must be considered. This utility model is designed so that the gas generated when the telescopic sleeve expands and contracts is expelled upwards through the shoe body. In this way, the shoe body forms a "breathable" sports shoe when worn. This type of shoe can solve the problems of sweaty feet and breathability, making it drier and more comfortable to wear.
[0025] This utility model protects the first, second, and third folding elastic components with a telescopic sleeve, while also beautifying the overall structure, making it more like a regular shoe and making it easier for the wearer to wear it in more occasions.
[0026] Compared with the prior art, the beneficial effects of this utility model are:
[0027] (1) This utility model uses a first folding elastic element as an elastic support element to realize the jumping function of the jumping shoe. In order to meet the changes of the human foot when walking, the junction of the forefoot and the arch of the shoe body is used as a rotating connection point to transfer the support plate and the first folding elastic element. In this way, when a person walks forward, the forefoot folds relative to the arch of the foot, and the support plate connected to the forefoot part of the shoe body can fold with the forefoot, which is in line with the ergonomic design. It fits the foot better when walking normally, making it easier to walk and control. It can also be walked normally when not jumping for entertainment. It can be worn for a long time and does not require a high level of venue, which improves the wearing experience and entertainment experience of this utility model.
[0028] (2) The second folding elastic element of this utility model provides better support for the support plate at the forefoot, so that the forefoot is less likely to fall forward when standing normally, further improving the overall stability; the third folding elastic element forms support inside the structure of the first folding elastic element, providing better support for the arch and heel of the shoe body, while improving the elasticity and support of the first folding elastic element. The second and third folding elastic elements together improve the jumping power and stability of the jumping shoe. Attached Figure Description

[0041] Example 1
[0042] like Figure 1 and Figure 2 As shown, a bouncy shoe includes a shoe body 1, and a support plate 2 and a first folding elastic element 3 respectively connected to the front and rear of the bottom of the shoe body 1. The support plate 2 and the first folding elastic element 3 are rotatably connected, and the connection point between the support plate 2 and the first folding elastic element 3 is located at the junction of the forefoot and the arch of the shoe body 1. The first folding elastic element 3 includes an integrally formed top layer, middle layer and bottom layer. A second folding elastic element 5 is connected between the support plate 2 and the bottom layer of the first folding elastic element 3, and a third folding elastic element 6 is connected between the top layer and the middle layer of the first folding elastic element 3.
[0043] like Figure 3As shown, there are two sets of first folding elastic elements 3, which are arranged side by side on both sides of the bottom of the shoe body 1. A straight connecting rib 31 and / or an X-shaped connecting rib 32 are also provided between the two sets of first folding elastic elements 3; there are also two sets of second folding elastic elements 5 and third folding elastic elements 6.
[0044] Designing two sets of first folding elastic elements side-by-side reduces the overall width and weight of the first folding elastic elements, making the entire jumping shoe lighter, easier to wear, and improving jumping performance. The straight connecting rib 31 or the X-shaped connecting rib 32 forms a stable connection between the two first folding elastic elements 3. Simultaneously, the two first folding elastic elements 3 can better transmit compressive force and deformation during jumping, resulting in better integration and jumping stability during movement.
[0045] like Figures 1 to 4 As shown, the support plate 2 and the first folding elastic element 3 are rotatably connected by a hinge 4.
[0046] In this embodiment, the length of the support plate 2 is equal to the total length of the forefoot and toe parts of the shoe body 1;
[0047] In this embodiment, the bottom length of the first folding elastic element 3 is greater than or equal to the overall bottom length of the shoe body 1.
[0048] The support plate 2 is mainly used to bear the pressure of the forefoot. The length of the support plate 2 cannot be too small, otherwise the wearer will not be stable enough when standing. After continuous testing, its length is controlled to be greater than or equal to the length of the forefoot part of the shoe body 1, and less than or equal to the total length of the forefoot and toe parts of the shoe body 1. This results in a better wearing experience and usage effect.
[0049] like Figure 2 and Figure 3 As shown, both ends of the bottom layer of the first folding elastic element 3 are provided with arc-shaped transition sections. Since the forefoot and heel both have a flipping motion with the ground when the wearer walks normally, the arc-shaped transition sections can better facilitate the switching of the foot during walking.
[0050] In this embodiment, the first folding elastic element 3 is a Z-shaped leaf spring, and the second folding elastic element 5 and the third folding elastic element 6 are multi-folded leaf springs. The connection method of the first folding elastic element 3, the second folding elastic element 5, and the third folding elastic element 6 can be integral molding or welding molding.
[0051] The advantage of this embodiment is that: Figure 3 and Figure 4As shown, the first folding elastic element 3 is used as an elastic support element to realize the jumping function of the jumping shoe. In order to meet the changes of the human foot when walking, the junction of the forefoot and arch of the shoe body 1 is used as a rotating connection point to connect the support plate 2 and the first folding elastic element 3. In this way, when a person walks forward, the forefoot folds relative to the arch of the foot, and the support plate 2 connected to the forefoot part of the shoe body 1 can fold with the forefoot, which conforms to the ergonomic design. It fits the foot better during normal walking, making walking and control easier. Normal walking is also possible when not using the jumping shoe for recreational purposes. The shoe offers enhanced wearing and entertainment experiences due to its long-term wearability and low venue requirements. Furthermore, the second folding elastic element 5 provides better support for the support plate 2 at the forefoot, preventing the forefoot from tipping forward during normal standing and further improving overall stability. The third folding elastic element 6 forms support within the structure of the first folding elastic element 3, providing better support for the arch and heel of the shoe body 1, while also improving the elasticity and support of the first folding elastic element 3. The combined effect of the second folding elastic element 5 and the third folding elastic element 6 enhances the jumping power and stability of the jumping shoe.

[0053] This embodiment is similar to Embodiment 1, except that in this embodiment:
[0054] like Figure 1 and Figure 2 As shown, the jumping shoe also includes a cushioning pad 7 disposed on the bottom layer of the first folding elastic member 3.
[0055] like Figure 1 As shown, the bottom of the cushioning pad 7 is provided with several anti-slip grooves 71.
[0056] It should be noted that, in order to improve the user experience, a cushioning pad 7 is designed at the bottom of the first folding elastic element 3. On the one hand, this can reduce the impact force during the bouncing process, reduce vibration, and improve the wearing experience; on the other hand, adding the cushioning pad 7 can reduce the wear of the first folding elastic element 3 and improve its service life; at the same time, the addition of the cushioning pad 7 can also enable the bouncing shoe of this embodiment to adapt to more ground conditions and improve its adaptability to different usage scenarios.

[0062] The two first connecting rods 91 and the second connecting rod are rotatably connected together in the middle to form an X-shaped intersection. When the first folding elastic element 3 is compressed and deformed, the shoe body will expand and contract in a balanced manner regardless of which side of the two first folding elastic elements 3 is subjected to force, after adjustment by the X-shaped element. The purpose of setting this balancing sliding element is to solve the problem of uneven force on various parts of the shoe body 1.

[0072] In this embodiment, the telescopic sleeve 8 is a plastic sleeve in the shape of an accordion tube.
[0073] In this embodiment, the first folding elastic element 3, the second folding elastic element 5, and the third folding elastic element 6 are protected by the telescopic sleeve 8, while the overall structure is beautified, making it closer to ordinary shoes and making it easier for the wearer to wear them in more occasions.
[0074] The other structures and principles of this embodiment are the same as those of Embodiment 1.
