Pressure trousers

Technical Field

The invention relates to a pair of pressure trousers, in particular to a pair of pressure trousers which can not only increase the exercise capacity during exercise, but also be comfortably worn in daily life.

Background

In the current busy and rapid pace of life, more and more adults are beginning to choose regular exercise, and data indicates that nearly one fifth of the population chooses daily exercise. In order to obtain good sports effect, a good pair of sports pants is needed. The pressure trousers in the sports trousers can not only effectively prevent lactic acid from accumulating and relieve fatigue, but also promote blood circulation, reduce muscle vibration and improve the sports effect. In many conventional compression pants, tubular fabrics are woven on a circular knitting machine, or different knitting structures are selected at different portions, so that different pressure values are obtained at the respective portions of the leg. These products often have the problems of lack of comfort, inconvenience in wearing, unregulated pressure and the like.

In addition, many inflatable clothes capable of adjusting pressure are available in the market at present. For example, chinese document CN210988371U discloses a pair of trousers with a locally adjustable inflation and pressurization device, which includes an inflation and deflation device, a pressure gauge, an air bag and a trousers deployment structure, wherein the inflation and deflation device, the pressure gauge and the air bag are all disposed on an inner side surface of the trousers deployment structure, which is in contact with a wearer. The waist and the legs of the trousers are of an expandable structure, and can be expanded or fixed under artificial control, the adjustable inflating and pressurizing device is arranged at the local part of the trousers, so that the trousers can be effectively pressurized and fixed in the using process, and can be uniformly pressurized, the operation area can be effectively pressurized, wrapped and fixed, and the gradient pressure can not be realized.

For another example, chinese patent document CN112165877a discloses a garment, specifically a garment in which an outer layer fabric and a lining are partially joined, air can be injected and discharged to form a plurality of air chambers which are divided into a plurality of parts and communicate with each other, and a resin film or a coating resin is laminated on at least one of the outer layer fabric and the lining.

Disclosure of Invention

The invention aims to provide the pressure trousers which can be used for randomly adjusting the pressure of the legs, realizing the stepped pressure of the legs and realizing daily wearing and sports wearing.

The technical solution of the invention is as follows:

the invention relates to pressure trousers, which comprise a leg pressure regulating area and a waist pressure regulating device, wherein the leg pressure regulating area comprises a thigh pressure regulating area and a shank pressure regulating area, the leg pressure regulating area consists of a body, an inflatable part and a covering fabric, the waist pressure regulating device is connected with the inflatable part, the inflatable part comprises a plurality of inflatable units, and the ratio V of the inflatable volume of the thigh inflatable unit to the inflatable volume of the shank inflatable unit meets the following formula: 1/10-woven fabric (V) woven fabric (1).

The pressure trousers of the invention realize the adjustability of the leg pressure by inflating and deflating the inflatable component through the waist pressure adjusting device. Under the state of no inflation, the trousers are convenient to wear like ordinary trousers, and are suitable for daily wearing. And under the inflation state, the pressure value of the trousers to the legs is increased, and the volumetric difference exists between the gas which can be filled into the trousers by the thigh inflation unit and the gas which can be filled into the shank inflation unit, thereby realizing the gradient pressure of the legs, meeting the different requirements of different parts of the legs on the pressure during exercise, relieving the fatigue, promoting the blood circulation, reducing the muscle vibration and improving the exercise effect.

Drawings

FIG. 1 is a rear view of a compression pant of the present invention. Wherein 1 is a waist pressure regulating device; 2 is a leg pressure regulating area; 3 is thigh pressure regulating area; 4 is a shank pressure regulating area; 5 is a body; 6, covering fabric; and 7 is an inflation unit.

Detailed Description

The pressure trousers comprise a leg pressure regulating area and a waist pressure regulating device, wherein the leg pressure regulating area comprises a thigh pressure regulating area and a shank pressure regulating area, the leg pressure regulating area comprises a body, an inflatable part and a covering fabric, the waist pressure regulating device is connected with the inflatable part, the inflatable part comprises a plurality of inflatable units, and the inflatable units are communicated. Under the same condition, the more the inflation unit is inflated, the larger the pressure value provided for the leg part is. The ratio of the inflatable volume of the thigh inflatable cells to the inflatable volume of the lower leg inflatable cells is critical in order to create a gradient pressure in the leg. If the ratio of the two is 1, namely the inflation volume of the thigh inflation unit is the same as that of the shank inflation unit, the gradient pressure is not formed. If the ratio of the volume of the gas to be filled in the thigh inflating unit and the volume of the gas to be filled in the lower leg inflating unit is less than 1/10, the pressure of the lower leg is too high, the blood circulation is affected, and even discomfort is caused, so that the ratio V of the volume of the gas to be filled in the lower leg inflating unit and the volume of the gas to be filled in the lower leg inflating unit is required to satisfy the following formula: 1/10-woven fabric (V) woven fabric (1). The gas charged here is air.

Preferably, in the pressure pants of the present invention, the leg-pressure adjusting region is of a front-piece type, a rear-piece type or a full-covering type, and there is no inflatable member at the front and rear of the knees. The front-type design means that the inflatable parts are only distributed on the front sides of the thighs and the calves, the rear-type design means that the inflatable parts are only distributed on the rear sides of the thighs and the calves, and the full-coverage design means that the inflatable parts are distributed on the front sides of the thighs and the calves and also distributed on the rear sides of the thighs and the calves. In the present invention, no inflatable member is provided in front and rear of the knee, considering that the inflatable unit is inflated and may affect the bending of the knee. The invention preferably adopts a rear-piece design, which not only can provide enough wrapping and supporting force for the legs from the rear, but also can maintain the inside of the trousers in a proper temperature and humidity environment to avoid excessive sultriness.

The pressure trousers comprise a plurality of inflatable units, and the volume size of each inflatable unit is directly related to the pressure value which can be provided for the leg. Under the same condition, the larger the volume of the inflation unit is, the more gas can be filled, and the higher the pressure value is provided. Preferably, the volume range of the single inflatable unit of the thigh part is 0.004-500 cm³The volume range of a single inflation unit of the shank part is 0.016-1000 cm³At the same time, every 100cm of the thigh inflatable part²The number of the inflatable units is 1-2500, and the inflatable parts of the lower leg part are per 100cm²The number of the aeration units is 1 to 1250. If the volume of the single inflatable unit of the thigh part is less than 0.004cm³If the number of the inflatable units arranged on the thighs is large, the thighs cannot feel the change of the pressure value after inflation; while the volume of the single inflatable unit of the thigh part is higher than 500cm³Every 100cm²The only one inflation unit is arranged in the middle, so that the problem that the thigh pressure value is too large and the normal movement cannot be realized is caused. Similarly, if the volume of the single inflation unit at the lower leg part is less than 0.016cm³The number of the inflatable units needed to be arranged on the lower leg part is large, and the lower leg part cannot feel the change of the pressure value after being inflated; while the lower legThe volume of the single inflation unit is higher than 1000cm³Per 100cm²The number of the inflatable units is only one, so that the problems that the pressure value of the lower leg part is too large, the normal movement cannot be realized and the blood circulation is influenced can occur. As a further preference, the volume range of the single inflatable unit of the thigh part is 0.2-50 cm³The volume range of a single inflation unit at the lower leg part is 1-60 cm³At the same time, every 100cm of the thigh inflatable part²The number of the inflation units is 5-100, and the lower leg part inflation parts are every 100cm²The number of the aeration units in the aeration tank is 5 to 50. More preferably, the volume of the single inflatable unit of the thigh part ranges from 0.5 cm to 20cm³The volume range of a single inflation unit at the lower leg part is 1.5-30 cm³At the same time, every 100cm of the thigh inflatable part²The number of the inflatable units is 10-100, and the inflatable parts of the lower leg part are every 100cm²The number of the aeration units in the aeration tank is 5 to 35.

According to the pressure trousers, the size of the pressure value after the pressure trousers are inflated and the sustainability of the pressure value are determined by the size of the air permeability of the material used for the inflation part, and if the air permeability of the material of the inflation part is too high, a small amount of air leakage can occur after the inflation part is inflated, so that the long-term use of the pressure trousers is influenced. Therefore, it is preferable in the present invention that the material for the inflatable member has an air permeability of not more than 0.2cm³/(cm²·s)。

The material for the material used for the inflatable member in the present invention is not particularly limited, and Thermoplastic Polyurethane (TPU), polyurethane (PU), and the like can be exemplified.

The pressure trousers have important influence on the pressure value, the wearing comfort and the like due to the longitudinal and transverse elastic elongation of the body. If the longitudinal and transverse elastic elongation of the body is less than 20%, after the inflatable component is inflated, the inflatable component is difficult to press the skin surface, and the perception of the human body to the pressure tends to be reduced; and the ease of putting on and taking off the garment by the human body tends to be poor. If the longitudinal and transverse elastic elongations of the body are all higher than 200%, the pressure generated after inflation will be absorbed by the elasticity of the fabric, and the human body may not feel the oppressive feeling. Therefore, in the present invention, it is preferable that the elastic elongation in the longitudinal and transverse directions of the body is 20% to 200%.

The main body of the present invention is not particularly limited, and may be a woven fabric or a knitted fabric. When the body is a woven fabric, the weave is not particularly limited, and may be a plain weave, a twill weave, a satin weave, or a multiple weave. When the body is a knitted fabric, the structure is not particularly limited, and the knitted fabric may be a circular knitted fabric or a warp knitted fabric. The fiber material used for the main body is not particularly limited, and Polyester (PET), polyamide (NY), cotton, polyurethane, and the like can be exemplified.

The extension rate of the covering fabric of the pressure trousers also influences the pressure value of the pressure trousers. The covering fabric is the fabric which is positioned at the outermost side of the pressure trousers and covers the inflatable component. When the inflatable member is inflated, it stretches toward the cover fabric side, and if the stress is 0.5N or less in all of the longitudinal and transverse directions of the cover fabric at an elongation of 1%, the pressure on the skin surface is reduced, and the pressure sensitivity of the human body tends to be reduced. Therefore, in the present invention, it is preferable that the stress at 1% elongation in both the longitudinal and transverse directions of the covering fabric is higher than 0.5N. More preferably, the stress at 1% elongation in the longitudinal and transverse directions is 0.5 to 1N, so that the trousers can be worn comfortably while sufficiently pressing the skin.

The present invention will be further described with reference to examples and comparative examples. The characteristics of examples and comparative examples were measured in the following manner.

After the inflation unit to be tested is inflated with gas, the end, far away from the inflation unit, of the gas guide pipe is plugged, so that the gas is prevented from overflowing. The measuring cylinder (1000 ml) filled with water is placed in a water tank filled with water, the height of the water in the water tank exceeds the bottom of the measuring cylinder, then the filled gas is introduced from the lower part through a gas guide tube, a gas plug is pushed out from the inside of the gas guide tube, and the volume of the filled gas is directly read after the gas enters the measuring cylinder.
