Description

Ankle protector capable of changing pressure

Technical Field

The invention belongs to the technical field of protectors, and relates to an ankle protector capable of changing pressure.

Background

Dorsi extension and dorsiflexion are the most form of sprain of the foot. Dorsum of foot extension: the foot moves forward of the lower leg, namely the colloquial expression is "foot hooking", if the lower leg is calculated as a reference horizontal line, the action of making the included angle between the instep and the lower leg smaller than 90 degrees is instep extension, the action is mainly completed by the contraction of the extensor longus tendon of the instep and other extensor tendons of four toes, and the instep extension is seen as the bulge of the instep tendon. During dorsi extension, the pressure on both sides behind the ankle increases while the pressure on the instep decreases. Toe bending: when the ankle is in the normal function position, the tibialis anterior muscle contracts, and upward tilting movement of the dorsum of the foot (namely, the angle between the dorsum of the foot and the tibialis anterior is reduced, the distance is close), the common language is 'tightening' of the foot, the angle between the dorsum of the foot and the lower leg is more than 90 degrees, and the foot moves towards the plantar direction, which is toe bending. During toe flexion, the pressure on both sides behind the ankle decreases, while the pressure on the instep increases.

With the trend of population aging and low fertility rate, the number of elderly people will increase sharply, and they will not be able to encounter stairs or walk on uneven road in life, and they will be prone to accidents such as foot sprain during walking due to age, muscle degeneration. On the other hand, physical contact, and even physical countermeasures (e.g., basketball, football, etc.), are often experienced by individuals interested in sports, where the most likely cause of injury is injury caused by accidental contact between the feet and legs of two teams of athletes during the holding process, which is often unavoidable. For this reason, most people wear such braces during exercise.

There are many types of ankle protectors on the market, including stretch socks, which provide compressive support to the ankle of a user; a functional sock with a soft, resilient pad provides support for the ankle portion of a user. However, such a protective gear is either uncomfortable for the user or does not provide a good protective effect. An important reason for this disadvantage is that it is derived from conventional elastic fabric materials, and in order to prevent such materials from loosening, the seams of the brace are long because the zipper or velcro form relatively thick seams which can cause discomfort to the user during movement. Another reason is that when the brace is designed to be worn against the skin, it is not able to provide the user with the pressure he needs according to his requirements, which has a certain impact on the protective effect product.

The functional socks with soft elastic protection pads can provide supporting support for the ankle of a user through materials such as rubber, silica gel and the like, but because each individual is independent, the shape of each individual is fixed with the supporting force provided by each individual in the ankle movement process of a human body, so that the pressure at the ankle cannot be correspondingly changed along with the ankle movement, and the situation firstly causes discomfort of wearing of the user; second, a corresponding variable supporting effect cannot be achieved with ankle movement.

Detailed Description

The invention will be described in detail below with reference to the drawings and the detailed description.

The invention relates to an ankle protector capable of changing pressure, which is shown in fig. 1-5, and structurally comprises an elastic belt element 11, wherein the elastic belt element 11 forms an L-shaped tubular structure, the elastic belt element 11 is sleeved with an ankle region, two ends of the tubular L-shaped tubular structure are respectively provided with an upper inlet 13 and a lower outlet 14, the upper inlet 13 and the lower outlet 14 are respectively positioned above the ankle and at the instep, and the elastic belt element 11 is positioned at the ankle and embedded with a variable pressure element 12.

The variable pressure member 12 includes an air bag a16 and an air bag b17 which are respectively embedded at positions of both sides of the rear of the ankle when the elastic band member 11 is positioned at the ankle where the back extension occurs, and an air bag 15 which is respectively embedded at a position of the instep and the calf where the pressure increase is greatest when the elastic band member 11 is positioned at the ankle where the toe flexion occurs, wherein the upper and lower ends of one side of the air bag 15 are respectively communicated with the upper and lower ends of the air bag a16 through an air belt 18 and an air belt a19, and the upper and lower ends of the other side of the air bag 15 are respectively communicated with the upper and lower ends of the air bag b17 through an air belt b20 and an air belt c 21.

The air bag 15, the air bag a16 and the air bag b17 are filled with air, and the air bag 15, the air bag a16 and the air bag b17 are communicated into a whole through the air belt 18, the air belt a19, the air belt b20 and the air belt c 21.

Two air belts 18, a19 or b20 and c21 on the same side of the ankle are respectively positioned on the upper and lower sides of the most protruding bones of the ankle, namely, on the upper and lower sides of the lateral malleolus 22 and the medial malleolus 23.

The shape of the air bag 15, the air bag a16 and the air bag b17 is consistent with the shape of the ankle.

The elastic band element 11 adopts an absorptive permeable material, such as a bamboo fiber material, and the bamboo fiber has a unique porous structure, so that the elastic band element has the special effects of strong moisture absorption and release, good softness and elasticity, natural high-strength antibacterial, bacteriostatic, mildew-proof and mite-proof effects, and can effectively remove peculiar smell and make feet fresh and comfortable all-weather.

The variable pressure element 12 is preferably a non-absorbent impermeable semi-rigid material, such as a flexible rubber material, that provides a soft, comfortable feel to the user.

The elastic belt member 11 and the variable pressure member 12 are sewn by a seamless integral weaving process, so that the seam between the elastic belt member and the variable pressure member is smoothly transited, and the wearing comfort of the user is improved.

The variable pressure element 12 of the present invention is composed of 3 air bags and 4 air bags, namely an air bag 15, an air bag a16 and an air bag b17, an air bag 18, an air bag a19, an air bag b20 and an air bag c21, wherein the three air bags are communicated by the 4 air bags, so that the air is transferred between the air bags in the dorsi stretching and toe bending process.

The positions and shapes of the air bags 15, a16 and b17 depend on the ankle dorsiflexion and toe Qu Shi, the most pressure change region and the outline shape of that region, and the comfort of the user is improved.

According to the invention, the positions of the air belts 18, the air belt a19, the air belt b20 and the air belt c21 are respectively connected with three air bags, and the arranged positions of the air belts bypass two positions of the protruding bones at two sides of the ankle, namely the two positions of the outer ankle 22 and the inner ankle 23, so that air can be smoothly conducted and transferred, and the situation that the air bag pipeline is pressed on the protruding positions of the bones to cause uncomfortable wearing of a user can be avoided.

During the ankle dorsiflexion, the ankle compresses the air bag a16 and the air bag b17 behind the ankle, so that the air is transferred to the air bag 15, the volume of the air bag 15 on the instep is increased, and more pressure is provided for the instep, thus preventing the ankle from further dorsiflexion and accidents; during ankle plantarflexion, the ankle compresses the bladder 15 on the instep, causing the transfer of air to bladder a16 and bladder b17 behind the ankle, the bladder a16 and bladder b17 increasing in volume, providing greater pressure on both sides behind the ankle, which prevents further ankle plantarflexion from occurring.

The elastic belt member 11 of the present invention is selected from an absorbent permeable material. This ensures that the material will absorb moisture, whether moisture from perspiration during the user's movement or moisture or humidity from the nature. This further ensures that the user does not suffer from wearing comfort due to moisture.

The variable pressure element 12 of the present invention comprises a bladder 15, a bladder a16, a bladder b17, a bladder 18, a bladder a19, a bladder b20, and a bladder c21 of a non-absorbent impermeable semi-rigid material. This ensures that the material does not absorb moisture, whether moisture from perspiration during the user's movement or moisture or humidity from the nature. This further ensures that the bladder does not interfere with its function by penetrating moisture, in addition to which the semi-rigid material provides the most basic pressure support for the ankle.

The seam between the variable pressure element and the elastic band element 11 is gentle and excessive, and excessive pressure at the seam due to excessive thickness at the seam is avoided, which improves the comfort of the user when wearing the belt.
