Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a shoe with an anti-sprain protection device. Background Art

[0002] In basketball games, professional players often reach sprint speeds of more than 7m / s, with a total movement distance of 4,400 to 7,500 meters and more than 50 jumps, which puts great pressure on the ankle joints. According to statistics, more than 70% of basketball players have experienced ankle sprains, and the possibility of secondary injuries is as high as 80%. Ankle sprains account for 90% of ankle injuries, and 15% will cause fractures. Ankle injuries have become one of the important injury factors that seriously affect the careers of basketball players.

[0003] The main ways to prevent ankle sprains are to use protective structures of sports shoes, ankle straps, ankle taping, etc. However, too much protection will limit the flexibility of the ankle joint and have an adverse effect on athletic performance. Ankle sprains often occur when physical strength is significantly reduced. At this time, the leg and foot muscle strength decreases, and the nervous system reaction also becomes slower. The speed and effect of handling abnormal conditions of the foot are greatly reduced, making sprains more likely to occur.

[0004] However, various protective devices are mostly fixed, and even if they can be adjusted by tightening, they cannot be adjusted during intense competitions and sports. Utility Model Content

[0005] The purpose of the utility model is to provide a shoe with an anti-sprain protection device, by arranging an inflatable airbag structure on the inner and outer sides of the ankle joint of the human foot to adjust the pressure of the airbag on the ankle joint according to the exercise time or intensity. The specific technical method is as follows:

[0006] A shoe with an anti-sprain protection device comprises a sole and an upper. At least one air bag is relatively arranged on the inner and outer sides from the shoe collar to the sole. An inflation control component is connected to the air bag. The inflation control component can monitor movement information during exercise and adjust the volume of the air bag according to the movement information to regulate the pressure of the air bag on the human foot.

[0007] Furthermore, the airbag corresponds to the ankle joint of the human foot, and the number of the airbags is set to be more than two to adjust the volume of the airbags in the corresponding areas around the ankle joint respectively.

[0008] Furthermore, the airbags are arranged in layers from top to bottom so as to adjust the volume of the airbags in different regions in the longitudinal direction.

[0009] Furthermore, the number of airbags is set to three, namely the first chamber, the second chamber and the third chamber. The first chamber is set at the collar position of the shoe, and the first chamber, the second chamber and the third chamber correspond to the upper, middle and lower parts of the ankle joint of the human foot respectively.

[0010] Furthermore, the first chamber, the second chamber, the third chamber and the sole are in contact with each other, so that the upward deformation of the airbag after inflation is greater than the downward deformation.

[0011] Furthermore, each airbag includes a first surface and a second surface, and the first surface and the second surface are arranged opposite to each other and correspond to the inner side and the outer side of the ankle joint of the human foot, respectively.

[0012] Furthermore, the airbag also includes a third surface and / or a fourth surface, the third surface is covered on the area of ​​the foot near the heel, and the left and right ends of the third surface point to the first surface and the second surface respectively, and the fourth surface is covered on the back side of the heel, and the left and right ends of the fourth surface point to the first surface and the second surface respectively.

[0013] Furthermore, the first surface, the second surface, the third surface and / or the fourth surface of the airbag can be arbitrarily connected to each other or spaced apart to form different airbag shapes.

[0014] Furthermore, a processor is provided in the inflation control component, a motion sensor and an air pressure sensor connected to the processor, and an air pump and an air release valve connected to the processor, so that the processor controls the air pump and the air release valve after collecting information from the motion sensor and the air pressure sensor.

[0015] Furthermore, the exercise information monitored by the inflation control component includes exercise time and exercise intensity.

[0016] Furthermore, it also includes an air tube, one end of which is connected to the inflation control component, and the other end is connected to the airbag.

[0017] Furthermore, the inflation control component may be disposed in the sole or the tongue.

[0018] The shoe with the anti-sprain protection device of the utility model has the following advantages:

[0019] By setting airbags on both sides of the ankle joint of the foot and using sensors to collect information such as exercise duration and intensity, fatigue is calculated and judged. After reaching a certain level of fatigue, the airbags at specific positions are inflated to strengthen the wrapping and tightening and increase the height of the shoe upper. This achieves a certain balance between protecting the ankle joint of the foot and maintaining the flexibility of the ankle joint. In particular, the impact of the protective device on flexibility and athletic performance is reduced in the early stages of exercise, and the protection is enhanced after fatigue has occurred after a period of exercise.

[0025] In order to better understand the purpose, structure and function of the present invention, the shoe with an anti-sprain protection device of the present invention is described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1 As shown, a sole 100 with an anti-sprain protection device is provided, and an upper 200 is arranged on the sole 100. The side of the shoe body close to the inner side of the human foot is defined as the inner side of the shoe body, and the side of the shoe body close to the outer side of the human foot is defined as the outer side of the shoe body. The end close to the toe is defined as the front side, and the end close to the heel is defined as the rear side. Then, below the shoe collar, corresponding to the inner and outer areas above the sole 100 at the shoe collar position, one or more inflatable airbags 300 are relatively arranged, and the inflatable airbags 300 are used to replace the leather, fabric and other materials of the upper 200. Preferably, the airbags 300 on both sides correspond to the ankle joints of the human foot. The airbags 300 usually adopt chambers divided into multiple strips or blocks to facilitate the thickness of the airbags 300 in each area after inflation.

[0027] The inflation control component 400 is connected to the airbag 300. During the exercise, the sensor set in the inflation control component 400 is used to collect data such as exercise duration and exercise intensity to calculate and judge fatigue. When a certain degree of fatigue is reached, the airbag 300 at a specific position is inflated to increase the thickness and height of the airbag 300, thereby strengthening the covering and tightening of the ankle joint of the human foot, and increasing the height of the shoe upper, thereby limiting the range of motion of the ankle joint of the human foot, increasing motion damping, and achieving the effect of strengthening the protection of the ankle joint and reducing the risk of ankle joint injury. In addition, applying pressure to the ankle joint can improve the proprioception of the person, increase the reaction speed of the nervous system to abnormal conditions of the foot, and further reduce the risk of ankle sprains.

[0028] Among them, the inflation control component 400 includes a processor set in the inflation control component 400, a motion sensor and an air pressure sensor connected to the processor, an air pump and an air release valve connected to the processor, and a battery. The inflation control component 400 can be installed on the midsole of sports shoes, corresponding to the arch of the human foot, and can also be installed on the heel, tongue and other positions of the sole 100.

[0029] An inflation control component 400 is built into the shoe, and the inflation control component 400 is connected to the air bag 300 through the air pipe 500 to realize automatic inflation of the air bag 300. A working logic structure of the inflation control component 400 is as follows: Figure 2 As shown, the motion sensor can be a single-axis or multi-axis acceleration sensor, a vibration sensor, etc. The processor calculates the exercise time, exercise intensity, and other data based on the data of the motion sensor, wherein the exercise intensity may include step length, stride, step frequency, walking cycle, pace, peak and mean of plantar pressure distribution, and information on dynamic pressure changes. When the exercise time or exercise intensity is monitored to exceed the set threshold, the processor controls the air pump to start and inflate the airbag 300. At the same time, the processor detects the air pressure in the airbag 300 through the air pressure sensor, and stops inflating when the preset air pressure value is reached. When the exercise is finished, the processor can control the opening of the deflation valve to release the high-pressure air in the airbag 300 and return to the uninflated state.

[0030] The shoes containing the above-mentioned anti-sprain protection device achieve a certain balance between protecting the ankle joint of the foot and maintaining the flexibility of the ankle joint. Specifically, the impact of the protection device on flexibility and sports performance is reduced in the early stage of exercise, and the protection is enhanced after fatigue occurs after a period of exercise.

[0031] In order to better understand the purpose, structure and function of the present invention, the shoe with an anti-sprain protection device of the present invention is further described in detail below with reference to the accompanying drawings, taking the specific structure of the airbag 300 as an example.

[0032] Embodiment 1, as Figure 1 As shown, the upper 200 and the sole 100 constitute the main structure of the shoe, and the air bag 300 is arranged around the heel and the shoe collar, and can be connected to the upper 200 and the sole 100 by sewing or gluing to replace the original upper 200 heel and shoe collar.

[0033] Preferably, three airbags 300 are provided, namely a first chamber 301, a second chamber 302 and a third chamber 303. The first chamber 301 is provided at the collar position of the shoe, and the second chamber 302 and the third chamber 303 are provided in sequence from top to bottom. The first chamber 301, the second chamber 302 and the third chamber 303 correspond to the upper, middle and lower parts of the ankle joint of the human foot, respectively. A sprain of the ankle joint of the foot is commonly caused by inversion and eversion of the ankle joint, that is, excessive rotation of the ankle joint to the inside or outside, causing a sprain. Therefore, the airbags 300 are relatively arranged in the lateral direction pointing outward from the inside of the shoe. By increasing the inflation amount of the airbags 300, the mobility of the heel area of ​​the human foot, especially the lateral activity space of the ankle joint area, can be limited, thereby increasing the motion damping and reducing the risk of ankle sprain. Moreover, by arranging the chambers from top to bottom, the volume of the airbags 300 can be adjusted by region in the longitudinal direction, and the mobility of the ankle joint in the lateral direction can be flexibly adjusted.

[0034] Among them, the first chamber 301, the second chamber 302 and the third chamber 303 are arranged around the ankle joint of the foot in an annular structure. Specifically, each chamber can be divided into a first surface, a second surface, a third surface and a fourth surface. The first surface and the second surface are arranged opposite to each other, corresponding to the inner and outer sides of the ankle joint of the human foot respectively. The third surface is covered on the foot surface area close to the heel, and the left and right ends of the third surface are respectively connected to the first surface and the second surface of the chamber. The fourth surface is covered on the back side of the heel, and the left and right ends of the fourth surface are respectively connected to the first surface and the second surface of the chamber, so that each chamber forms a connected closed ring structure. Therefore, after the chamber is inflated, a relative pressure pointing to the ankle joint of the foot is formed between the first surface and the second surface, and between the third surface and the fourth surface. Through the mutual traction and compression between the chambers, the ankle joint is wrapped and its range of motion is restricted to a certain extent to reduce the risk of sprain.

[0035] Since the diameter of the human ankle joint gradually increases when extending toward the ankle joint, that is, the diameter gradually increases when extending from the shoe collar to the middle of the shoe cavity, the first chamber 301, the second chamber 302 and the third chamber 303 form an arc structure on the inner and outer sides to conform to the curvature changes of the human foot shape and fully wrap the ankle joint of the foot.

[0036] Furthermore, the first chamber 301, the second chamber 302, the third chamber 303 and the sole 100 are in contact with each other, so that after the airbag 300 is inflated, the deformation between each other is limited. In particular, since the sole 100 is in direct contact with the ground and the ground is fixed, the limitation of the downward deformation of each chamber is increased, thereby guiding the chamber to deform upward. In particular, the first chamber 301 is located at the collar of the shoe and there is no stopper above it. Subsequently, the overall upward deformation of the airbag 300 is greater than the downward deformation, which is equivalent to increasing the height of the shoe upper, increasing the clamping force of the ankle joint of the foot extending toward the ankle, and further improving the stability of the ankle joint of the foot.

[0037] The second embodiment is the same as the first embodiment in terms of the number and arrangement of layers, but is different from the first embodiment in that the airbag 300 is divided into six chambers, such as Figure 3 As shown, it includes two oppositely arranged first chambers 301, two oppositely arranged second chambers 302, and two oppositely arranged third chambers 303. The first chamber 301, the second chamber 302 and the third chamber 303 are only provided with a first surface and a second surface of a rectangle.

[0038] The purpose of the above-mentioned setting is, on the one hand, to reduce the amount of material used for the airbag 300, and setting it into a common rectangular shape is convenient for processing and manufacturing. On the other hand, it is combined with the structural characteristics of the upper 200 itself, especially for the case where the height of the foot is relatively high and the shoelace system extends upward from the foot to the collar. If the airbag 300 is set at the foot and other positions, it will conflict with the shoelace system and other structures.

[0039] After being inflated, the first chamber 301, the second chamber 302 and the third chamber 303 increase in the lateral and front-to-back directions of the ankle joint of the human foot, exerting relative pressure on the ankle joint to tighten the ankle joint and limit its range of motion. At the same time, after being inflated, the first chamber 301, the second chamber 302 and the third chamber 303 also increase in longitudinal height. Since the bottom is fixed to the upper 200 and the sole 100, it can only increase upward, which is equivalent to raising the upper, thereby further improving the stability of the ankle joint of the foot.

[0040] like Figure 4 and Figure 5 As shown, the first chamber 301, the second chamber 302 and the third chamber 303 are symmetrically arranged on both sides of the ankle joint 600. Before inflation, no pressure or movement limit is generated on the ankle joint 600. When the airbag 300 is inflated, the first chamber 301, the second chamber 302 and the third chamber 303 wrap the ankle joint 600 of the foot. When the foot continues to move, the chambers are pulled and squeezed by each other, and the movement of the ankle joint 600 is constrained to avoid excessive amplitude and excessive speed movement, thereby playing a role in preventing sprains.

[0041] Furthermore, the first surface, the second surface, the third surface and / or the fourth surface of the airbag 300 can be arbitrarily connected to each other or spaced apart to form different chamber shapes such as strips or blocks. Of course, the airbags 300 can also be arranged from front to back or with a certain tilt angle. The number, position relationship and shape of the specific chambers can be arbitrarily combined, as long as the chambers can achieve relative pressure on the ankle joint area on both sides of the inside and outside to wrap it and achieve the effect of motion restriction.

[0042] The material of the airbag 300 includes but is not limited to rubber, polyolefin, polyamide, polyester and other materials. The airbag 300 is relatively soft when not inflated, similar to leather and fabric. It has no pressure in the direction perpendicular to the surface of the ankle joint and can slide along the surface of the ankle, so it will not restrict the movement of the ankle joint in all directions.

[0043] The terms “above”, “below” and “within” mentioned above include the number itself; the terms “exceed” and “outside” do not include the number itself.

[0044] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be understood as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model. The various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the various possible combinations of the embodiments of the utility model will not be described separately.

[0045] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.
