Technical Field

The invention relates to tight trousers, in particular to tight trousers capable of improving the exercise effect.

Background

With the importance of people on sports fitness, the demand for sports equipment is increasing, various sports equipment is ｡, most sports are related to leg movement, so that the protection of legs of sports groups is important, and many people use ｡ -type commodities such as leg protectors ､, leg stockings, tights and the like, which generally have the following properties: (1) the core muscle group is supported, and the explosive force of the muscle is fully exerted; (2) the knee, the ankle and the muscle which are easy to be injured are supported, so that the injury is reduced; (3) promoting blood circulation to promote the speed of oxygen transmission and waste discharge of muscles, thereby shortening the energy generation time of muscles, reducing lactic acid accumulation, accelerating body recovery, and reducing fatigue ｡ it is usually considered to attach other materials with different elasticity to the body, such as polyurethane elastic resin film, high elastic net knitted fabric, high elastic woven fabric, etc.

The tights are convenient to move and are well received by people, but most of the tights are complicated in design, so that the pressure of clothes is too high, the tights are too bound to the body, and the tights are difficult to put on and take off. For example, patent document CN205267024U discloses a directional compression pants for muscle groups, which adopts high-pressure cloth in the leg muscle group area and the lower leg muscle group area, and applies a certain elastic pressure to the thigh muscle group and the lower leg muscle group in the vertical direction, so as to provide more concentrated wrapping force and stability for the key muscle groups; the elastic pressure is gradually decreased from the ankle to the shank to the thigh, so that the blood circulation is promoted, the lactic acid accumulation in the strenuous exercise is reduced, high-pressure cloth is arranged in front of and behind the knee to protect the knee, but the skin at the knee and the muscle is greatly stretched in the exercise process, so that the problems of difficulty in putting on and taking off, movement resistance and the like can occur when the tights are designed at the parts under high pressure, and particularly, the muscle is expanded in the later period of exercise to generate uncomfortable pressure.

Disclosure of Invention

The invention aims to provide a pair of tights which is easy to put on and take off and has good comfort, and can inhibit muscle vibration and improve exercise performance.

The technical scheme of the invention is as follows:

tights according to the present invention have both high tightening regions and low tightening regions in the circumferential direction of at least the lower leg portion, and the ratio in the circumferential direction from the ankle to the low tightening region in the abdomen of the leg is gradually increased ｡ in the unworn state

The compression gradient of the tights from ankles to the abdomen parts of the legs can promote blood circulation and relieve sports fatigue, and meanwhile, the tights have good sports following performance, can effectively inhibit muscle vibration during sports and improve sports performance; and the elastic band has no over-tight tightening force, is easy to put on and take off, and is suitable for daily wearing and wearing during sports.

Detailed Description

In order to achieve both of the following performance and a constant tightening force, the tights of the present invention have a high tightening region and a low tightening region in the circumferential direction of at least the lower leg portion, and have a ratio in the circumferential direction gradually increasing from the ankle to the low tightening region in the abdomen of the leg in an unworn state.

The high tightening region referred to herein specifically means a region having a relatively large recovery stress and a relatively low elongation.

The low-bundling-strength region referred to herein specifically means a region where the recovery stress is relatively small and the elongation is relatively high.

The ankle as used herein refers specifically to the area of the lateral malleolus approximately 10cm up from the distal malleolus.

The abdomen of the leg as referred to herein specifically means the maximum circumference of the posterior bulge of the lower leg.

If only the low tightening region exists in the circumferential direction of the lower leg portion, the tightening force becomes insufficient, and it becomes difficult to achieve the effect of suppressing the muscle vibration. On the other hand, if only the high tightening region exists in the circumferential direction of the lower leg portion, the effect of suppressing the muscle vibration can be achieved even if the tightening force is high, but there is a problem that putting on and taking off is difficult. Therefore, the present invention contemplates providing both the high tightening region and the low tightening region in the circumferential direction of the lower leg portion. Under the non-wearing state, the ratio of the low tightening area in the circumferential direction is gradually increased from the ankle to the abdomen of the leg, the tightening force can reach the gradient pressure which is gradually decreased from bottom to top, the blood circulation is promoted, and the wearing comfort is improved.

Preferably, the ratio of the low tightening area to the girth of the tights is gradually increased from 15% to 35% to 20% to 50% from the ankle to the abdomen of the leg in the unworn state; more preferably 20% to 30% to 25% to 40%.

The material used for the high-fastening region and the material used for the low-fastening region may be the same or different, and are not particularly limited. If the same fabric is selected, the design is carried out by utilizing different stretching characteristics of warp and weft, namely, the side with high stretching recovery stress is arranged along the circumference direction of the leg to be used as a high-tightening area, and the side with low stretching recovery stress is arranged along the circumference direction of the leg to be used as a low-tightening area. Or overlapping two fabrics to form a high-fastening area, and using a single fabric as a low-fastening area. The fabric used is preferably an elastic knitted fabric containing polyurethane fibers. The weave can be weft plain, warp velvet plain or other complex weaves and the like.

Preferably, the high cinch region and the low cinch region have different stretch characteristics ｡

Preferably, the low tightening region covers the triceps surae of the lower leg formed by the gastrocnemius and the soleus, and the connecting line between the high tightening region and the low tightening region is distributed along the triceps surae of the lower leg formed by the gastrocnemius and the soleus, so that the main muscles of the leg can freely vibrate in a small range during exercise, and fatigue does not occur.

In general, tights are worn with a lateral elongation of about 30%, and are likely to have a lateral elongation of about 80% when taken off ｡, preferably, the tights of the present invention have a recovery stress in the high tightening region that is 0.3 to 1.5N ｡ greater than the recovery stress in the low tightening region at 30% elongation in the leg circumferential direction, and the adjacent portions of the two regions are not so strong and weak as to cause discomfort despite a significant difference in garment pressure.

In consideration of comfort during wearing and prevention of muscle vibration, it is preferable that the tights of the present invention have a recovery stress of 0.5 to 2.5N in the high tightening region and a recovery stress of 0.1 to 1.2N in the low tightening region at 30% extension in the circumferential direction of the legs.

Preferably, the wearing elongation of the tights according to the present invention is gradually reduced from 15% to 60% to 5% to 45% from the ankle to the abdomen of the leg in a wearing state.

Preferably, the recovery stress of the low tightening region is gradually reduced from 0.5 to 3N to 0.1 to 2N ｡ from the ankle to the abdomen of the leg in the worn state, so that the wearing pressure is suitable and the muscular vibration can be suppressed.

The tights of the invention can gradually reduce the wearing elongation from the ankle to the abdomen of the leg in the wearing state, provide the gradient pressure (clothes pressure) which is gradually decreased from bottom to top, promote the blood circulation and improve the wearing comfort. On the contrary, if the elongation of the wear is gradually increased or unchanged from the ankle to the abdomen of the leg, only a gradient pressure is provided from bottom to top or no pressure is changed, which may hinder the blood circulation and promote fatigue.

Preferably, the tight index of the fabric forming the pants of the present invention is 1.5 or less in a worn state, and the difference between the elongation stress at 80% elongation and the recovery stress at 80% elongation is 5N or less. The tightness index here refers to the degree of tightness of the garment against the human body. When the tightening index exceeds 1.5, the leg is comfortable in a stationary state, but the coating feeling is strong in a moving state, the exercise following ability tends to decrease ｡, and when the difference between the elongation stress at 80% elongation and the recovery stress at 80% elongation exceeds 5N, there is a possibility that the leg is not easily put on and taken off although the leg is supported, or the leg is not supported although the leg is easily put on and taken off.

In the tights according to the present invention, the lower leg portion and the portion from the knee to the waist are sewn and connected, and at least the front-side sewing line is located at the lower end of the patella of the knee, and the portion corresponding to the knee is made of a fabric for the low-tightening region. Such a design facilitates knee movements, in particular knee bending movements, and may reduce slippage of the briefs.

Preferably, the tights according to the present invention are sewn and connected to the lower leg portion and the portion from the knee to the waist, and at least the sewing and connecting line on the rear side is located at the upper end of the knee fossa. The design can reduce the occurrence probability of folds generated after the knee is bent during the knee bending movement, and ensure the aesthetic property; and facilitates the recovery of the fold when the knee is bent to be straightened.

The tight trousers of the invention adopt the modes of edge joint, M seam and the like with smooth seams as much as possible when sewing in consideration of the comfort when wearing.

Preferably, the tights of the present invention have the possibility of affecting the exercise following ability ｡ when the elongation of the legs in the length direction is not less than 80% ｡ and not more than 80%

The present invention will be further described with reference to examples and comparative examples.

The method for testing and evaluating physical properties and the like according to the present invention is as follows:

(1) elongation (Fabric)

Using JIS L1096: 2010 elongation D method, using a mertess CMT6103 universal testing machine, under the following test conditions: clamping distance: 76mm, speed: 100mm/min, termination force: 22.1N, sample cloth size: 10cm × 15cm (3 blocks), elongation = (extension distance at termination force/grip-1) × 100%, averaged.

(2) Elongation stress and recovery stress

Using JIS L1096: 2010 elongation recovery E method, using a Medites CMT6103 universal testing machine, under the following test conditions: clamping distance: 76mm, width of nip 2.5cm, speed: 100mm/min, termination force: 22.1N, 5 cycles, sample cloth size: using the data for the first elongation and 5 th recovery, 10cm x 15cm (3 blocks), an elongation versus stress curve ｡ is plotted for elongation stress: reading the stress corresponding to the elongation on the elongation curve, and taking an average value; and (3) recovery stress: the stress at the corresponding elongation is read on the recovery curve and averaged.

(3) Elongation at wear

Firstly, marking the part of the tights needing to measure the wearing elongation, measuring the girth when the tights are not worn, then selecting a corresponding model of the tights according to leg data of' human body dimension data 2004-:

elongation at wear = (circumferential length when worn/circumferential length when not worn-1) × 100%

Low-fastening-region wearing elongation = (length of low-fastening region in leg circumferential direction when worn/length of low-fastening region in leg circumferential direction when unworn) × 100%.

(4) Tightness index

The test conditions of a Meits CMT6103 universal testing machine are as follows: sample cloth size: 10cm × 15cm (3 pieces), nip: 76mm, width of nip 2.5cm, speed: the test specimen was stretched to 110% at 300mm/min, and the stress at 30% elongation < N1> and the stress at 80% elongation < N2> were read and calculated according to the following formula, taking the average of 3 times: tautness index = ((stress at 80% elongation of test specimen < N1 >) -stress at 30% elongation of test specimen < N2>)/50) × 10.

(5) Clothes press

The contact pressure was measured using a contact pressure measuring instrument of AMI corporation of japan, and the tights were put on a manikin of a corresponding model using an air bag of diameter 20mm ｡, and the clothes pressure from ankle to abdomen of leg was measured, and 5 times of measurement were averaged.

(6) Amplitude of muscle vibration

Mark points were attached to the tights worn by 10 subjects at positions corresponding to the muscle belly (gastrocnemius) and bones (knee-ankle). The examinee jumps from a jumping platform with the height of 30cm to the ground ｡ fixed at a distance of 45cm from the jumping platform, the Vicon infrared motion capture system is utilized to capture displacement ｡ of a mark point in the jumping process, the vibration amplitude of different muscles is calculated through the displacement of the mark point, and the average ｡ is taken, so that the smaller the muscle vibration amplitude is, the smaller the muscle energy loss is, and the better the motion effect can be. Sensory evaluation results (average value) of the tightening feeling and the ease of exercise of 10 subjects were collected at the same time, and the larger the rank value is, the better the effect is.

(7) Difficulty in wearing and taking off

The 10 male testees stand with the same width of feet and shoulders, and put on and take off the male testees in two steps: directly mentioning the waist for finishing; removing: directly taking off the ankle and finishing. In the above procedure, the subject wears and takes off the tight pants by himself/herself, and the ease of wearing and taking off is evaluated ｡ 1: difficult, 2: less easy, 3: it is easy. The larger the scale, the easier the putting-in and putting-out.
