The present invention relates to the technical field of apparel, and particularly, to a dynamic elastic one-way water-guiding sportswear which achieves an integration of improving the kinesthetic sense, maintaining movement stability and safety, in particular focusing on mechanics and thermal-moisture comfort and during stretching and contraction process of dynamic exercise of human body.
Sports enthusiasts and professional athletes will unavoidably be injured in training and competition, and common sports injuries include: abrasions, ligament injury and muscle strain, and more serious injuries are dislocation and fracture. Among the most popular sports, football and basketball bring a greater chance of sports injury, and the commonly injured parts are muscle strain and joint injury of the legs, feet, knees, waist and back; for the other popular sports such as badminton, golf and volleyball, if the athlete is not skillful damages to the muscle and joint may result. The injured parts are mostly parts with relative large dynamic movement, such as waist and abdomen muscle groups, shoulder joints, shoulder muscle groups, and so on. No matter what kind of sports injuries occur, they have a common reason, which is reduction of body fitness and functions, muscle sensitivity and movement stability, and change or abnormality in technical movements caused by prolonged overloaded training or during competition. Therefore, in addition to paying attention to the techniques of the sports during usual training and doing warm-up exercise before playing, it is also a very feasible measure to wear an effective sports protection equipment for the purpose of effectively preventing sports injuries. The sports protection equipment are used not only for providing dynamic support to soft tissues and joints and helping recovery of the sports injuries in a traditional sense, but also should primarily aim at improving the kinesthetic sense through the activation of soft tissue receptors, accelerates the brain and motor nerve feedback speed to effectively control and affect muscle response, and delays exercise fatigue in the process of improving kinesthetic sense, so as to achieve the purposes of improving athletic performance and helping to prevent sports injuries.
In the patent searches, it has been found that, both in China and abroad, the focus of existing sportswear/equipment having protective functions are on the exterior design. For example, Chinese Patent CN 102613725 A disclosed a new type of sportswear which may be used as a sports bag after folding. Furthermore, 458 design patents for sportswear including CN 202907816 U, CN103462246 A, CN 87301120 and the like are revealed in a patent search with SIPO. There are also a number of patents on protective sportswear, such as European Patent EP1810649B1, and Japanese Patent CA2584636 A1, describing a sports equipment for providing a greater frictional force on the inner surface of the clothing to simulate the effect of bandage on the muscles and joints, so as to prevent abrasions, contusions, muscle strain, sprains and fractures. There are also a number of patents for the protection of local position such as European patent EP2478783 A1 providing a special design for the protection of male genital organ, and Chinese patent CN 202407149 U proposing a design including sports top wear and pants, together with the shoulder sheath, waist sheath, knee sheath and ankle sheath. These patents provide a design concept from the perspective of protection. But there is no relevant patent for invention on the combination and application of the material property with the characteristics of the body parts and stretching and changes of the muscles of the wearer during exercise, especially, applicable invention of bio-functional designs in view of the characteristics of body stretching during exercises involving a degree of movement of the whole body. There is also no relevant patent on the designing of a sports equipment with a view to improving the kinesthetic sense and movement stability. Further, there is no wearing test to verify change in the kinesthetic sense of the wearer of these sports equipment.
Furthermore, a good sports equipment needs, in additional to the all-round protective functions, considerations on the thermal and humid comfort during the dynamic stretching process of the body when the equipment is worn. A large number of research results show that: during exercise, the various parts of the body will have repeated stretching and contraction, a lot of heat is generated in the process and most of heat is taken away in the form of sweat evaporation. After sweating, due to the slow evaporation rate of sweat, the loss of heat on the surface of the skin is blocked and the core body temperature continues to rise, thus affecting the athletic performance, meanwhile the wearer feels uncomfortable due to the wet and sticky clothes. There are also athletes saying that, after the rapid evaporation of water, they often feel wet and cold when taking a rest, due to the sharp decline in the temperature of the skin surface. For outdoor sports (such as golf, marathon, etc.), the wet and cold feeling from the sweat is especially obvious that the comfort of the wearer is affected. Therefore, considerations on a good sports equipment should not only be about its protective function, but also the wearing comfort when the human body is stretching and contracting during the process of dynamic exercise.
The technical problem to be solved by the present invention is that, in view of the above-mentioned deficiencies of the prior art, there is provided a dynamic elastic one-way water-guiding sportswear which achieves an integration of improving the kinesthetic sense, maintaining movement stability and safety, in particular focusing on mechanics and thermal-moisture comfort, during stretching and contraction process of dynamic exercise of human body.

Therefore, during the stretching and contraction process of dynamic exercise of the human body, the sportswear can provide a corresponding elastic protection and thermal-moisture comfort, an integration of improving the kinesthetic sense, maintaining movement stability and safety.
The invention will now be described in further detail with reference to the accompanying drawings, and in which:
To facilitate a clear understanding of the technical features, objects and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to
Wherein, the stretching ratio of the covered skin determines the dynamic transferring and guiding capability for liquid water as: measuring the stretched size of the skin at a corresponding part of the human body when standing and in the state of movement, and obtaining the stretching ratio of skin according to the skin stretched size so as to obtain the stretching ratio of lining (i.e., the level of changes caused to the fabric structure), and determining the dynamic transferring and guiding capability for liquid water according to the stretching ratio of skin, wherein, the corresponding relationship between the stretching ratio of the basic cloth and the dynamic transferring and guiding capability for liquid water is shown as in Table 1 below.
As can be seen from the above table, when the stretching ratio of the lining of the basic cloth is 50% or less, the dynamic transferring and guiding capability for liquid water is level 1 or above, and when the stretching ratio of the lining is more than 50%, the dynamic transferring and guiding capability for liquid water is level 4 or above.
Preferably, in the region of the pressure fastening area 2, being an area where the skin is stretched and perspiration is more likely to occur, the region of the basic cloth corresponding to the pressure fastening area 2 has a better dynamic transferring and guiding capability for liquid water than other regions. Referring to Table 2, which is a requirement grading table on the lining stretching ratio and the dynamic transferring and guiding capability for liquid water of the region of the basic cloth corresponding to the pressure fastening area 2.
As can be seen from the above table, for the pressure fastening area 2, when the stretching ratio of the lining is 30% or less, the dynamic transferring and guiding capability for liquid water is level 1 or above, and when the stretching ratio of lining is more than 30%, the dynamic transferring and guiding capability for liquid water is level 4 or above.
In other words, each region can achieve perspiration function but the water guiding capability is not the same, which is considered comprehensively according to the stretching ratio of skin and perspiration in each region, to achieve maintaining normal body temperature when the wearer is static, and to effectively adsorb and rapidly discharge sweat to the fabric surface so as to take away the heat from the skin surface during exercise.
Wherein, the method for providing “a porous material having a dynamic adsorption and transfer function for liquid water” is known in the art, and reference may be made to Chinese patent application “Design Principle and Manufacturing Method of a Porous Material Having a Dynamic Adsorption and Transfer Function, 201210378024.1”. The measurement method for the composite index on the dynamic transfer of liquid water can be found in the national standard GB21655.2-2009, Evaluation of Wetness and Quick-Drying of Textiles, Part 2, Dynamic Moisture Transfer Method.
Wherein, the elastic stretchable band comprises an oblique stretchable band 1_1 and a longitudinal stretchable band 1_2:
The longitudinal stretchable band 1_2 starts from the upper part of the knee joint, stretches along the vertical axial direction of the human body, covers the region where the thigh muscle of the human body is located, and provides elastic stretching and protection for the quadriceps and the knee joint;
The oblique stretchable band 1_1 comprises at least one shoulder strap and two mesh leg protection bands. The shoulder strap starts from a shoulder on one side of the human body, extends obliquely across the upper body on the front and the back sides of the human body, and converges on the other side of the body at a pressure fabric strip at the top of the longitudinal stretchable band 1_2. The mesh leg protection bands extend downwardly from the convergence point of the shoulder strap, bypass the poples, the knee joint, and the longitudinally stretchable band 1_2, and wrap the tissues at the two sides of the thighs and around the knees.
For example, when there are two shoulder straps, they intersect each other at the chest and the back to form two X-shaped structures. If there is only one shoulder strap, part of a shoulder strap above the intersection point of the two shoulder straps in the two shoulder straps configuration is removed, to form two “inverted Y” shape structures at the chest and the back.
It should be understood that basic design style of the sportswear of the present invention may be adjusted according to the various climate and difference in the types of sports, such as sleeve/sleeveless, trousers/shorts, collar/collarless, and so on. Hereinafter, specific embodiments of the dynamic elastic one-way water-guiding sportswear according to the present invention will be described with reference to specific sports.
The first embodiment is for a golf player. Different sports have different sports specific analysis methods and results, and a golf swing action is one of the relatively complicated actions in sports. In the whole swing and shot action, most muscles of the body will participate in the entire swing action through stretching and rapid contraction to provide energy for an accurate and effective shot. Therefore, taking the golf swing and shot action as an example, the muscle group and important joints involved in actions including standing, gripping the golf club, aiming, backswing, swinging, and finishing etc. are analyzed in detail. And taking the golf as an example to divide regions and discuss the design and fabric requirements.
With reference to
More preferably, an anti-slip strip is provided at an opening for wearing the sportswear, such as sleeve openings, shoulder straps, trouser legs openings, and the like. The anti-slip strip is designed to prevent the clothes from moving up and down along with the stretching of the wearer's body during the wearing process, and thereby guarantees the effectiveness of the dynamic elasticity of the equipment.
Specifically, the elastic stretchable band comprises an oblique stretchable band 1_1 and a longitudinal stretchable band 1_2. The design of the oblique stretchable band 1_1 and the longitudinal stretchable band 1_2 can be flexibly changed according to the type of sport. For example, as for golf in the present embodiment, the left and right shoulders of the human body have different movement manifestations in the whole swing, so that different designs are required for the left and right shoulders. For example, during backswing, the right shoulder joint of right-handed athletes mainly shows outward rotation and retraction movements, while the left side shoulder joint shows abducent, inward rotation and stretching states, during which, triceps and supraspinatus are the mainly involved muscle groups, and after finishing of the backswing, they are ready to pass the power to a club at any time like a tight slingshot to complete the process of effective swing and shot. During the process from swinging to finishing, the arm muscles and rotator cuff muscle group quickly contract to pass the power to the hitting point quickly, and assist the center of the whole body to shift and maintain the balance of the body. The probability of injury for the left shoulder of a professional golfer is second only to the most vulnerable waist and wrists. In order to prevent the shoulder joint from exceeding its maximum range of movement or related muscle strain caused by the inertia due to the rapid action of swing during the process of finishing, the design of the shoulders of the sportswear should have the function of helping stretching of the triceps and rotator cuff muscle group, and effective braking to protect the shoulder joints.
Therefore, the oblique stretchable band 1_1 of the present invention comprises one shoulder strap and two mesh leg protection bands. This embodiment removes part of a shoulder strap above the intersection point of the two shoulder straps in the two shoulder straps configuration.
Since the leg muscle groups such as quadriceps are coordinated with the internal oblique and external oblique muscle during the whole swing, they play a major role in helping the hip and knee joints to effectively rotate and maintaining body balance and stability. Therefore, the design for the longitudinal stretchable band 1_2 of the leg is: using a highly elastic fabric designed to wrap the thigh muscles and the upper tissue of the knee joint along the direction of quadriceps, so as to enhance kinesthetic sense and movement stability.
During the whole golf swing, waist and abdomen muscle groups and back muscle groups of the human body, such as erector spinae muscle, latissimus dorsi and lateral oblique muscle etc., play a major role in maintaining the upper body upright and balanced, and improving the stability during the swing. The waist and abdomen muscle groups provide torque for the rapid rotation of the body during the swing, and provides the braking for rapidly stopping the rotation of the upper body after the shot, with respect to all golfers, no matter professional or amateur.
Therefore, the pressure fastening area 2 is cylindrical, and fastens the lower part of the abdominal wall muscle group and the back muscle group. The upper edge of the pressure fastening area 2 takes the lower boundary of the sternum as a reference and the lower edge takes the boundary of the iliac crest of the pelvis as a reference.
In addition, in the present invention, the whole sportswear is formed from a dynamic water-removing lining, but each region may preferably use a lining made of a porous material having dynamic adsorption and transfer function for liquid water, respectively. That is to say, the dynamic transferring and guiding capability for the liquid water of the lining in different regions may be different and may be determined based on the stretching ratio of the skin in the corresponding region. The Young's moduli of the elastic stretchable band and the pressure fastening area 2 are also determined based on the stretching ratio of the skin in the corresponding region. For example, for the regions in the back and abdomen, the stretching ratio of which during exercise is often smaller than that in the shoulders, but perspiration in these regions is more than that of the shoulders, the water transferring and guiding capability of such region can be enhanced when these regions are stretched.
In the present invention, according to the stretching characteristic of human skin, the elasticity of the lining fabric of the oblique stretchable band 1_1 and of the lining fabric of the longitudinal stretchable band 1_2 provided to the wearer is different. The Young's modulus of the oblique stretchable band 1_1 is preferably 0.06 to 0.07 MPa, and the Young's modulus of the longitudinal stretchable band 1_2 is preferably 0.07 to 0.09 MPa. The fabric structure of the pressure fastening area 2 is preferably a close fabric structure mainly providing elasticity and pressure. Here, the fabric is designed to provide to the wearer a Young's modulus 1-2 times, preferably 1.5 times, of that of the regional elastic stretchable band.
In order to enable each functional region to achieve the function of improving the kinesthetic sense and improving the stability and protection, the present invention also provides specific requirements on the design of the various regions and on the lining used, respectively:
oblique stretchable band 1_1: mainly used to protect the left shoulder, designed as a highly elastic shoulder strap (clearly, mainly used to protect the right shoulder for a right-handed person, and the shoulder strap is selected depending on the circumstance) to provide a strong movement stretching and feeling, respectively obliquely pulled to the bottom of the thigh on the other side and connected to the pressure fabric strips at the bottom of the thigh, and a mesh leg protection band wrapping two sides of the thighs and tissues around the knees. The width of the shoulder strap is 1-5 cm, preferably 3 cm. The Young's modulus of the fabric is 0.06-0.07 MPa, and in a process of 0% to 50% fabric stretching deformation, the composite index on the dynamic transfer of liquid water ≥level 1, but when the fabric stretching is more than 50%, the composite index on the dynamic transfer of liquid water ≥level 4, to maintain normal body temperature when the wearer is static, and to effectively adsorb and rapidly discharge sweat to the fabric surface to take away heat during exercise, achieving the function of dynamic elastic one-way water guiding. This sportswear can provide a pressure of 15-37 mmHg on the upper part of the shoulder strap, a pressure of 5-8 mmHg on the front chest, and a pressure of 5-12 mmHg on the back.
Longitudinal stretchable band 1_2: a highly elastic fabric designed to wrap the thigh muscles and tissues at the upper part of the knee joint along the direction of quadriceps to enhance the kinesthetic sense and movement stability. Its fabric structure is designed to mainly provide elasticity and pressure, so as to enhance the kinesthetic sense of the leg muscle group. Here, the fabric structure is designed to provide a preferred Young's modulus of 0.07-0.09 MPa to the wearer. The water guiding capability of this part is the same as that of the oblique stretchable band 1_1. This sportswear can provide the pressure of 10-20 mmHg on the front of the thigh.
Pressure fastening area 2: covering about two-thirds of the waist and abdomen region containing the anterior abdominal muscle group and the lower half of the back muscle group, such as the latissimus dorsi and the lumbar fascia, in a circular manner. The fabric design of this area is preferably a close fabric structure mainly providing pressure, and can effectively protect the waist and abdomen muscle groups and assisting rotation of the upper body. Here, the fabric structure is designed to provide to the wearer a Young's modulus of 1-2 times, preferably 1.5 times, of that of the area 1. In a process of 0% to 30% fabric stretching deformation, the composite index on the dynamic transfer of liquid water ≥level 1, but the when fabric stretching is more than 30%, the composite index on the dynamic transfer of liquid water ≥level 4. In order to better enhance the sportswear's support and protection of the waist and abdomen, this set of equipment is further equipped with a highly elastic waist band of width 10-30 cm, preferably 20 cm, the tightness of which can be adjusted. This waist band can be used alone or as an additional component to be used together with the equipment. This sportswear can provide a pressure of 6-12 mmHg for the abdomen, and a pressure of 8-19 mmHg on the waist.
In order to enhance its aesthetics appearance, and meet the requirements of more athletes, in this implementation, the design of the crotch portion in the lower body part of the sportswear in
This embodiment is directed primarily to soccer. According to the characteristics of the soccer sport, on the basis of the first and second embodiments, a similar design is adopted with similar requirement on the fabric used to provide a soccer sportswear having the same function.
The elastic stretchable band of this sportswear is slightly modified from the design of the golf sportswear: the left and right shoulders are designed as a highly elastic shoulder strap. The width of the shoulder strap is 1-5 cm, preferably 3 cm. The fabric on both sides of the shoulders is designed to provide a greater pressure to protect the shoulder joints and muscles, and to provide a stronger sports stretching and kinesthetic sense. Here, the fabric structure is designed with a Young's modulus of 0.06-0.07 MPa. In the process of 0% to 50% fabric stretching deformation, the composite index on the dynamic transfer of liquid water ≥level 1, but when the fabric stretching is more than 50%, the composite index on the dynamic transfer of liquid water ≥level 4, to maintain normal body temperature when the wearer is static, and to effectively adsorb and rapidly discharge sweat to the fabric surface to take away heat during exercise achieving the function of dynamic elastic one-way water guiding. This sportswear can provide a pressure of 15-37 mmHg on the upper part of the shoulder strap, a pressure of 5-8 mmHg on the front chest, and a pressure of 5-12 mmHg on the back.
