Description

[Technical Field]

[0001] This application relates to the technical field of sports training, and in particular to weighted jackets. [Background technology]

[0002] Weight jackets are widely used as important aids to enhance training effects and improve muscle strength and endurance in various fields, such as sports training, rehabilitation, and military training. However, existing weight jackets still have many deficiencies in design and use, and are in urgent need of improvement and innovation.

[0003] Conventional weight jackets primarily use solid fillers, such as sandbags or lead. These fillers are hard and lack flexibility. When players or users perform large-amplitude movements, such as bending, lateral bending, or twisting, they can easily come into contact with their lower back or hands, causing discomfort and hindering natural body movements, reducing the comfort and effectiveness of training. Furthermore, the solid fillers are concentrated, making them difficult to flexibly adjust to the user's body type and movement needs. This results in uneven weight distribution and impacts balance and coordination.

[0004] Subsequently, liquid-filled weighted jackets have appeared on the market, which utilize the fluidity of liquid to allow weighted clothing to better fit the human body to a certain extent and improve wearing comfort. Relevant prior art, for example, the Chinese patent application "Weighted Clothing for Tennis Training" (Application No. CN202320505593.1) discloses a garment comprising a garment body and a weighted body, the weighted body being liquid, a plurality of weighted pockets on both the front and back of the garment body, filled cavities formed in the weighted pockets, and the weighted body being placed in the filled cavities. In this application, liquid is used as a filling material for the weighted clothing, and utilizing the fluidity of the liquid, the weighted clothing can better fit the player and improve wearing comfort.

[0005] However, liquid-filled weighted jackets also have serious drawbacks. On the one hand, the liquid filler must have extremely high sealing properties, and if the garment is locally torn, liquid leakage is likely to occur. This not only soils the garment and the surrounding environment, but can also render the weighted jacket unusable and significantly shorten its service life. On the other hand, liquid-filled weighted jackets pose significant risks when washed. The intense rotation, impact, and twisting of the washing machine can cause fatigue and damage to the seams and seals of the weighted pockets, leading to liquid leakage. Once liquid leakage occurs, the weighted jacket becomes virtually unusable. In response to the above-mentioned problems of conventional weighted jackets, the present application proposes a new type of weighted jacket. Summary of the Invention [Problem to be solved by the invention]

[0006] The technical problem to be solved by this application is to provide a weight jacket in which the weight-bearing structure is designed in appropriate locations and in which comfort and stability of the weight jacket during movement are ensured through rational structural design and material selection. [Means for solving the problem]

[0007] The technical solution used in this application is as follows: a weighted jacket, comprising a garment body, wherein the garment body is provided with weight bearing areas on both the front and back sides, wherein the garment body has a weight bearing layer filled in the weight bearing areas, the weight bearing layer being made of a high molecular weight polymer material and filled with weighting particles, wherein the weight bearing area on the front side of the garment body is referred to as the front weight bearing area, and the weight bearing area on the back side of the garment body is referred to as the rear weight bearing area, the front weight bearing area includes a left side area and a right side area, the left side area and the right side area are provided symmetrically and independently of each other, and the rear weight bearing area is an integral structure.

[0008] Compared with the prior art, the advantages of the present invention are as follows: First, the weight-bearing layer is made of a high molecular weight polymer material, which is more flexible than the conventional solid filling materials such as sandbags and lead, and can better conform to the curves of the human body and fit snugly to the body during movement, improving wearing comfort.

[0009] The front weight bearing area is divided into a left area and a right area, which are independent of each other. The independent left and right weight bearing areas can adjust their force bearing conditions according to the body's movement state, avoiding the excessive pressure on one side of the body that can be caused by the one-piece design of conventional weight jackets, and allowing for more natural and comfortable movement on both sides of the body.

[0010] The rear weight bearing area is a one-piece structure, and this design helps maintain balance at the rear of the body. The one-piece rear weight bearing area can distribute the load evenly, avoiding body swaying and imbalance situations caused by uneven weight distribution, and improve stability during movement.

[0011] Furthermore, compared to liquid-filled weighted jackets, weighted layers made of high-molecular-weight polymer materials offer significantly improved durability. Liquid-filled weighted jackets require extremely high sealing performance, which can easily lead to leakage if ruptured. Weighted layers made of high-molecular-weight polymer materials eliminate this leakage problem. They have relatively good tear resistance and can withstand external forces such as pulling and twisting during movement, reducing the risk of damage to the weighted jacket due to localized tearing, thereby extending the weighted jacket's service life. Unlike liquid-filled weighted jackets, which pose significant washing risks, weighted jackets with weighted layers made of high-molecular-weight polymer materials are easier to clean. Unlike liquid-filled weighted jackets, there is no need to worry about tearing the weighted pockets due to the spinning, impact, and twisting of the washing machine during washing. This makes it easier to clean the weighted jacket after daily use, allowing it to maintain its cleanliness. At the same time, washing does not affect its structure or function, further improving the weighted jacket's durability.

[0012] The present application's rational structural design and material selection ensure the comfort and stability of the weight jacket during movement, providing users with a good experience and more reliable support in scenarios such as daily training, professional competition, or rehabilitation.

[0013] In some embodiments of the present application, the garment body has a vest-like structure, the rear weight-bearing region has an overall X-shaped structure, the left region and the right region both have curved band-like structures, and the center of the left region protrudes toward the right region, and the center of the right region protrudes toward the left region.

[0014] The vest-like design is easy to put on and take off, making it suitable for a variety of sports, especially those requiring upper limb movement, such as weightlifting and throwing, without restricting arm movement. The X-shaped rear weight-bearing area better distributes the load evenly across the back, reducing localized pressure and improving stability, while also better adapting to body twisting during movement. The curved left and right bands better fit the lumbar curve, avoiding discomfort during movement and allowing for independent adjustments to suit the movement needs of each side.

[0015] In some embodiments of the present application, the front weight bearing region covers a waist portion of the garment body, and the rear weight bearing region covers a back portion of the garment body. In the present application, the positions of the weight bearing regions are rationally arranged.

[0016] In some embodiments of the present application, the garment body includes an inner layer and an outer layer, both of which are made of elastic fabric, which has excellent elasticity and breathability, can adapt to body movements, reduce friction and restrictiveness, and improve wearing comfort.

[0017] Preferably, both the inner and outer layers are made of Lycra nylon spandex fabric, which is readily available commercially. Such materials are strong and durable, able to withstand the pulling and twisting that comes with movement while maintaining the shape and performance of the garment and extending its useful life.

[0018] In some embodiments of the present application, the garment body includes an inner waterproof layer and an outer waterproof layer, the inner waterproof layer and the outer waterproof layer being positioned between the inner layer and the outer layer, the inner waterproof layer being closely attached to the inner side of the inner layer, and the outer waterproof layer being closely attached to the inner side of the outer layer. The inner waterproof layer and the outer waterproof layer can effectively prevent water from entering, protect the human body and the weight-bearing layer from moisture for a long time, maintain the comfort of the human body, and maintain the performance and service life of the weight jacket.

[0019] Preferably, both the inner and outer waterproof layers are made of SBR neoprene, which is readily available. This material has excellent waterproof and abrasion resistance, and can withstand various environmental conditions such as washing and daily use, while maintaining its waterproof performance and further improving the durability of the weight jacket.

[0020] In some embodiments of the present application, a weight-bearing layer is provided between the inner and outer waterproof layers in the weight-bearing area, made of polyurethane, and the weight-bearing particles are iron sand. Polyurethane materials have excellent flexibility and tear resistance, allowing them to better adapt to body movements while maintaining the structural stability of the weight-bearing layer. The iron sand particles have a high density, allowing them to provide a large load within a small volume. At the same time, the iron sand particles are uniformly dispersed, preventing localized excessive loads and improving the uniformity and stability of the load.

[0021] In some embodiments of the present application, a flexible cooling layer is provided between the weight-bearing layer and the inner waterproof layer, which can provide localized cooling as the body heats up during movement, helping to reduce body temperature, reduce fatigue, and improve comfort during movement.

[0022] In some embodiments of the present application, the flexible cooling layer is made from a cooling hydrogel, which has excellent flexibility and cooling properties, allowing it to maintain its cooling effect during movement without affecting the overall performance and comfort of the weighted jacket.

[0023] Based on common knowledge in this field, the above embodiments can be combined in any manner. [Brief explanation of the drawings]

However, those skilled in the art will understand that these drawings are drawn only to help understand the preferred embodiments and should not be construed as limiting the scope of the present application.

[Figure 4] 1 is a schematic diagram of a cross-sectional structure of a garment body of the present application. [Figure 5] 1 is a schematic cross-sectional view of a weight bearing area of ​​the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0025] The present invention will be described in detail below with reference to the drawings.

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be described in more detail below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are only for the purpose of interpreting the present application, and are not intended to limit the present application.

[0027] In Example 1, as shown in FIGS. 1 and 2 , the weighted jacket includes a garment body 1, with weight-bearing areas 2 on both the front and back of the garment body 1. The weight-bearing areas 2 are filled with a weight-bearing layer 3 made of a high-molecular-weight polymer material, which is filled with weighting particles 4. Compared to conventional solid fillers such as sandbags or lead, this material has greater flexibility. It conforms well to the curves of the human body and fits snugly to the body during movement, improving comfort. Compared to liquid-filled weighted jackets, the weight-bearing layer 3 made of a high-molecular-weight polymer material is significantly more durable. Liquid-filled weighted jackets require extremely high sealing performance, which can easily lead to leakage if ruptured. However, the weight-bearing layer 3 made of a high-molecular-weight polymer material eliminates this leakage problem. Its relatively excellent tear resistance allows it to withstand external forces such as pulling and twisting during movement, reducing the risk of damage to the weighted jacket due to localized tearing and thereby extending the weighted jacket's service life. Unlike liquid-filled weighted jackets, which pose significant risks when washing, weighted jackets with a weight-bearing layer 3 made of a high-molecular-weight polymer material are easier to clean. Unlike liquid-filled weighted jackets, there is no need to worry about the weighted pockets tearing during washing due to the spinning, impact, and twisting of the washing machine. This makes it easier to clean the weighted jacket after daily use, allowing it to maintain its cleanliness. At the same time, washing does not affect its structure or function, further improving the durability of the weighted jacket.

[0028] The weight-bearing area 2 on the front of the garment body 1 is referred to as the front weight-bearing area 5, and the weight-bearing area 2 on the back of the garment body 1 is referred to as the rear weight-bearing area 6. The front weight-bearing area 5 includes a left area 7 and a right area 8, which are symmetrically arranged and independent of each other, and the rear weight-bearing area 6 is an integrated structure. The independent left and right weight-bearing areas 2 can adjust their force-bearing conditions according to the body's movement state, avoiding the excessive pressure on one side of the body that can occur with the integrated design of conventional weight jackets and allowing for more natural and comfortable movement on both sides of the body. The rear weight-bearing area 6 is an integrated structure, which helps maintain balance at the rear of the body. The integrated rear weight-bearing area 6 distributes weight evenly, preventing body swaying and imbalance caused by uneven weight distribution and improving stability during movement.

[0029] Through rational structural design and material selection, the present application can ensure the comfort and stability of the weight jacket during movement, providing users with a good experience and more reliable support in scenarios such as daily training, professional competitions, or rehabilitation.

[0030] In Example 2, as shown in FIGS. 1 to 5 , the garment body 1 has a vest-like structure, the rear weight-bearing region 6 has an overall X-shaped structure, and the left and right regions 7 and 8 each have a curved, band-like structure, with the center of the left region 7 protruding toward the right region 8 and the center of the right region 8 protruding toward the left region 7. The vest-like structure is easy to put on and take off and is suitable for various sports, especially those requiring upper limb movement, such as weightlifting and throwing, without restricting arm movement. The X-shaped rear weight-bearing region 6 can better distribute the load, evenly distribute it across the back, reduce localized pressure, improve stability, and better accommodate body twisting during movement. The curved, band-like design of the left and right regions 7 and 8 can better fit the lumbar curve of the human body, avoiding discomfort during movement and allowing for independent adjustment according to the movement needs of both sides.

[0031] The front weight bearing area 5 covers the waist area of ​​the garment body 1, and the rear weight bearing area 6 covers the back area of ​​the garment body 1. In the present application, the weight bearing areas 2 are positioned in a rational manner.

[0032] The garment body 1 includes an inner layer 9 and an outer layer 10, both of which are made of elastic fabric. Elastic fabrics have excellent elasticity and breathability, allowing them to adapt to body movement, reducing friction and restrictiveness, and improving comfort. Preferably, both the inner layer 9 and the outer layer 10 are made of Lycra nylon spandex fabric, which is readily available. Such materials have high strength and durability, allowing them to withstand pulling and twisting caused by movement while maintaining the shape and performance of the garment and extending its service life.

[0033] The garment body 1 includes an inner waterproof layer 12 and an outer waterproof layer 11, which are positioned between the inner layer 9 and the outer layer 10. The inner waterproof layer 12 is attached closely to the inner side of the inner layer 9, and the outer waterproof layer 11 is attached closely to the inner side of the outer layer 10. The inner waterproof layer 12 and the outer waterproof layer 11 effectively prevent water penetration, protecting the human body and the weight-bearing layer 3 from moisture for extended periods, maintaining the human body's comfort, and maintaining the performance and service life of the weight jacket. Preferably, the inner waterproof layer 12 and the outer waterproof layer 11 are both made of SBR neoprene fabric, which is readily available. This material has excellent waterproof and abrasion resistance, can withstand various environments during washing and daily use, and at the same time, maintains its waterproof performance and further improves the durability of the weight jacket.

[0034] Within the weight-bearing area 2, a weight-bearing layer 3 is provided between the inner waterproof layer 12 and the outer waterproof layer 11. The weight-bearing layer 3 is made of polyurethane, and the weighting particles 4 are made of iron sand. Polyurethane materials have excellent flexibility and tear resistance, allowing them to better adapt to body movements while maintaining the structural stability of the weight-bearing layer 3. The iron sand particles have a high density and can provide a large load within a small volume. At the same time, the iron sand particles can be dispersed evenly, preventing localized excessive loads and improving the uniformity and stability of the load.

[0035] A flexible cooling layer 13 is provided between the weight-bearing layer 3 and the inner waterproof layer 12. As the body heats up during movement, the flexible cooling layer 13 can provide a localized cooling effect, helping to lower body temperature, reduce fatigue, and improve comfort during movement.

[0036] The flexible cooling layer 13 is made from cooling hydrogel, which has excellent flexibility and cooling performance, and can maintain cooling effect during movement without affecting the overall performance and comfort of the weight jacket.

[0037] Other details of the second embodiment are the same as those of the first embodiment.

[0038] The present application has been described in detail above, and the present specification uses specific examples to explain the principles and embodiments of the present application. However, the above examples are merely intended to facilitate understanding of the present application and its core ideas. Those skilled in the art may make various improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications are also within the scope of protection of the claims of the present application.
