Description

Technical field

[0001] The present application concerns the field of sports training technology and specifically relates to a weight vest. State of the art

[0002] In numerous fields such as athletic training, rehabilitation, and military training, weighted vests are widely used as an important training aid to enhance the training effect and improve muscle strength and endurance. However, existing weighted vests still suffer from numerous shortcomings in their design and application, which urgently require improvement and innovative further development.

[0003] Conventional weight vests predominantly use solid fillings such as sandbags and lead blocks. These filling materials are very rigid and inflexible. When the athlete or user performs large movements such as bending forward, lateral bending, or twisting, an uncomfortable pressure sensation can easily develop around the waist or hands, hindering natural body movement and reducing comfort and training effectiveness. Furthermore, solid fillings are usually relatively concentrated and difficult to adapt flexibly to the body shape and movement requirements of the user, resulting in uneven weight distribution that impairs balance and coordination.

[0004] Later, weight vests filled with liquid appeared on the market. The fluidity of the liquid allows the weight vest to conform better to the human body, thereby improving comfort. The relevant existing technology, such as the Chinese patent application "Weight Vest for Tennis Training," application number CN202320505593.1, discloses that it comprises a garment body and a weight body. The weight body consists of liquid; several weight pockets are arranged on the front and back of the garment body, forming filling chambers, and the weight body is positioned within these filling chambers. The present application also uses liquid as the filling material for the weight vest. The fluidity of the liquid allows the weight vest to conform better to the athlete, thus improving comfort.

[0005] However, liquid-filled weight vests also have significant disadvantages. Firstly, extremely high demands are placed on the tightness of the liquid filling. As soon as a local area of ​​the vest is damaged, the liquid easily leaks out. This not only soils clothing and the surrounding area but can also render the weight vest unusable and significantly shorten its lifespan. Secondly, there is a considerable risk when washing a liquid-filled weight vest: Under the strong rotation, impact, and twisting forces of a washing machine, the seams or seals of the weight pockets can become fatigued or cracked, leading to liquid leakage. Once a leak occurs, the weight vest is essentially unusable. To solve the aforementioned problems of existing weight vests, the present application proposes a novel weight vest. Contents of the utility model

[0006] The technical problem to be solved by the present application is to provide a weight vest which has flexible weight structures at suitable points and ensures the comfort and stability of the weight vest during movement through a well-thought-out structural design and the selection of suitable materials.

[0007] The technical solution used in the present application relates to a weighted vest comprising a garment body. Weighted areas are arranged on both the front and back of the garment body. A weight layer is arranged within these weighted areas. The weight layer consists of polymer material and incorporates weight particles. The weighted area located on the front of the garment body is referred to as the front weighted area, and the weighted area located on the back of the garment body is referred to as the rear weighted area. The front weighted area comprises a left section and a right section, which are arranged symmetrically and are independent of each other. The rear weighted area forms a single, monolithic structure.

[0008] Compared to the prior art, the present application offers the following advantages: First, the weight layer is made of polymer material. Compared to conventional solid fillings such as sandbags or lead blocks, this material exhibits greater flexibility. It can adapt better to body contours and remain close to the body during movement, thereby improving wearing comfort.

[0009] Secondly, the front weight area is divided into left and right sections, which are positioned independently. These independent left and right weight zones allow the load to be adjusted individually according to the body's movement, thus avoiding the problem of excessive pressure on one side of the body that can occur with conventional full-body weight vests. This allows for more natural and comfortable movement of both sides of the body.

[0010] The rear weight plate forms a single, continuous structure. This design helps maintain balance in the back of the body. The one-piece rear weight plate distributes weight evenly, preventing uneven weight distribution that could lead to body wobble or loss of balance, and improving stability during movement.

[0011] Furthermore, the weight layer made of polymer material offers significantly greater durability compared to liquid-filled weight vests. Liquid-filled weight vests are subject to very high requirements for leak-proofness. If damaged, the liquid easily escapes. A weight layer made of polymer material does not have this leakage problem. It possesses good tear resistance and can withstand the tensile, torsional, and other forces that occur during movement, thus reducing the risk of damage to the weight vest from localized tears and extending its lifespan. Unlike liquid-filled weight vests, which pose a considerable risk when washed, a weight vest with a weight layer made of polymer material is easier to clean.There is no need to worry about the weight vests tearing due to rotation, impact, or twisting during the washing machine cycle, as is the case with liquid-filled vests. This makes the weight vest easier to clean after daily use, keeps it clean, and ensures its structure and function are not affected by washing, further increasing its durability.

[0012] Through a well-thought-out structural design and the selection of suitable materials, this application ensures that the weight vest remains both comfortable and stable during movement. It offers users a better experience and more reliable support in scenarios such as daily training, professional competition, or rehabilitation treatment.

[0013] In some embodiments of the present application, the garment body has a vest-like structure. The rear weighted area forms an overall X-shaped structure, while the left and right areas each have a curved striped structure. The center of the left area curves to the right, and the center of the right area curves to the left.

[0014] The vest-like structure makes it easy to put on and take off and is suitable for various athletic scenarios, especially training methods that require upper extremity movements, such as weightlifting or throwing, without restricting arm movement. The X-shaped rear weight panel distributes weight more effectively, ensuring even weight distribution across the back, reducing localized pressure, and increasing stability. It also adapts better to the body's rotational movements during exercise. The curved strips on the left and right sides conform better to the curve of the lumbar region, preventing discomfort around the waist during movement and allowing for independent adjustment to accommodate the specific movement needs of the left and right sides of the body.

[0015] In some embodiments of the present application, the front weight area covers the waist position of the garment body, while the rear weight area covers the back position of the garment body. The present application provides for a well-considered arrangement of the weight areas.

[0016] In some embodiments, the garment body comprises an inner layer and an outer layer, both made of elastic fabric. The elastic fabric exhibits good elasticity and breathability, adapts to body movements, reduces friction and a restrictive feeling, and thus improves wearing comfort.

[0017] Preferably, the inner and outer layers are made of Lycra-nylon-spandex fabric, which can be sourced directly. This material exhibits high strength and durability, can withstand the tensile and torsional forces occurring during movement, and simultaneously maintains the shape and function of the garment, thus extending its lifespan.

[0018] In some embodiments of the present application, the garment body comprises an inner waterproof layer and an outer waterproof layer arranged between the inner and outer layers. The inner waterproof layer lies against the inside of the inner layer, and the outer waterproof layer lies against the inside of the outer layer. The inner and outer waterproof layers effectively prevent the penetration of moisture, protect the body and the weight layer from long-term exposure to moisture, and maintain both the wearer's comfort and the performance and lifespan of the weight vest.

[0019] Preferably, the inner and outer waterproof layers are made of SBR neoprene, which can be sourced directly. This material offers good water and abrasion resistance, can withstand washing and various conditions of daily use, and retains its water-repellent properties, further increasing the durability of the weight vest.

[0020] In some embodiments of the present application, a weight layer is arranged in the weight zones between the inner and outer waterproof layers. The weight layer consists of polyurethane, and the weight particles consist of iron sand. Polyurethane material exhibits good flexibility and tear resistance, adapting better to the body's movements while maintaining the structural stability of the weight layer. Iron sand particles have a high density, allowing a high weight to be achieved in a small volume. At the same time, the particles can be evenly distributed to avoid excessive local weight and to increase the uniformity and stability of the weight.

[0021] In some embodiments of the present application, a flexible cold storage layer is arranged between the weight layer and the inner waterproof layer. During movement, the body generates heat, and the flexible cold storage layer can provide local cooling, lower body temperature, reduce fatigue, and improve wearing comfort during exercise.

[0022] In some embodiments of the present application, the flexible cold storage layer consists of cooling hydrogel. This material exhibits good flexibility and cold storage performance, can maintain a cooling effect during movement, and does not affect the overall performance or wearing comfort of the weight vest.

[0023] Based on the expertise in this field, the embodiments described above can be combined with each other as desired.

[0024] The present application discloses in particular a weight vest for use in sports training technology. It comprises a garment body with a weighted area on both the front and back. Within the weighted area, the garment body contains a weight layer made of high-molecular-weight material. This weight layer contains weight particles. The weighted area located on the front of the garment body is referred to as the front weighted area, and the weighted area located on the back is referred to as the rear weighted area. The front weighted area comprises a left and a right area, which are arranged symmetrically and independently of each other. The rear weighted area forms a single-piece structure.The present application has designed a flexible weight structure in the appropriate areas, and through appropriate structural planning and material selection, it is ensured that the weight vest offers comfort and stability to the wearer during training.

[0027] The present matter will be explained in detail below with reference to the attached figures.

[0028] To clarify the purpose, technical solution, and advantages of the present application, it will be described in more detail below with reference to the figures and embodiments. It should be understood that the specific embodiments described below serve only for illustrative purposes and do not limit the scope of protection of the present application.

[0029] A weight vest according to embodiment 1 is in Fig. 1 and Fig. Figure 2 shows a garment body 1. A weight compartment 2 is provided on both the front and back of the garment body 1. A weight layer 3, made of a polymer material, is arranged within the weight compartment 2. Weight particles 4 are embedded in the weight layer 3. Compared to conventional solid fillings such as sandbags or lead blocks, this material exhibits significantly better flexibility. It conforms better to the body's contours and fits snugly against the body during movement, thus improving comfort. The weight layer 3, made of the polymer material, is considerably more durable than liquid-filled weight vests. Liquid-filled weight vests have high requirements for watertightness; if damaged, they can easily leak.The weight layer 3, made of a polymer material, is not subject to this risk. It possesses exceptional tear resistance and can reliably absorb tensile, torsional, and other external forces during movement. This reduces the risk of localized damage and extends the lifespan of the weight vest. Unlike liquid-filled weight vests, which pose a significant risk during washing, a weight vest with a polymer weight layer 3 is considerably easier to clean. There is no need to worry about the weight vests tearing due to rotation, impact, or twisting in the washing machine, as is the case with liquid-filled vests.This makes it easier to clean the weight vest after daily use, keeps it clean and does not affect its structure and function through washing, thus further increasing the durability of the weight vest.

[0030] The weight zone 2 located on the front of the garment body 1 is referred to as the front weight zone 5, and the weight zone 2 located on the back is referred to as the rear weight zone 6. The front weight zone 5 comprises a left zone 7 and a right zone 8, which are arranged symmetrically and independently of each other. The rear weight zone 6 forms a single, independent structure. The left and right independent weight zones 2 can individually adjust the load according to the body's movement, thus avoiding the problem of excessive load on one side of the body, which can occur with conventional one-piece weight vests. This allows for natural freedom of movement and increases comfort on both sides of the body. The rear weight zone 6, as a single-piece structure, helps to maintain balance in the back area.A one-piece design of the rear weight area 6 ensures an even distribution of weight, prevents imbalance or excessive swaying of the body and increases stability during movement.

[0031] Through a well-thought-out structural design and the selection of suitable materials, this application ensures that the weight vest remains both comfortable and stable during movement. It offers users a better experience and more reliable support in scenarios such as daily training, professional competition, or rehabilitation treatment.

[0032] Exemplary embodiment 2, shown in Fig. 1 to Fig.5: The garment's main body 1 has a vest-like structure. The rear weighted section 6 forms an overall X-shaped structure, while the left section 7 and the right section 8 each have a curved, striped structure. The center of the left section 7 curves towards the right side 8, and the center of the right section 8 curves towards the left side 7. The vest-like structure facilitates donning and doffing and is suitable for various athletic scenarios, particularly training methods that require upper extremity movements, such as weightlifting or throwing, without restricting arm movement. The X-shaped rear weighted section 6 distributes weight more effectively, ensuring even weight distribution across the back, reducing localized pressure, and increasing stability. Simultaneously, it adapts better to the body's rotational movements during exercise.The curved strips of the left area 7 and the right area 8 better adapt to the curve of the body's lumbar region, avoid discomfort in the waist area during movement, and can be independently adjusted according to the movement requirements of the left and right sides of the body.

[0033] The front weight zone 5 covers the waist position of the garment body 1, and the rear weight zone 6 covers the back position of the garment body 1. The present application provides for a well-thought-out arrangement of the weight zones 2.

[0034] The garment body 1 comprises an inner layer 9 and an outer layer 10, both made of elastic fabric. This elastic fabric offers good elasticity and breathability, adapts to body movements, reduces friction and a restrictive feel, and thus improves wearing comfort. Preferably, the inner layer 9 and the outer layer 10 are made of Lycra-nylon-spandex fabric, which can be readily sourced. This material exhibits high strength and durability, can withstand the tensile and torsional forces occurring during movement, and simultaneously maintains the garment's shape and function, thereby extending its lifespan.

[0035] The garment body 1 also 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 lies against the inside of the inner layer 9, and the outer waterproof layer 11 lies against the inside of the outer layer 10. The inner waterproof layer 12 and the outer waterproof layer 11 effectively prevent moisture penetration, protect the body and the weight layer 3 from prolonged exposure to moisture, and maintain both the wearer's comfort and the performance and lifespan of the weight vest. Preferably, the inner waterproof layer 12 and the outer waterproof layer 11 are made of SBR neoprene, which is readily available.This material has good water resistance and abrasion resistance, can withstand both washing processes and the various conditions of daily use, and retains its water-repellent properties, further increasing the durability of the weight vest.

[0036] In weight zone 2, a weight layer 3, made of polyurethane, is positioned between the inner waterproof layer 12 and the outer waterproof layer 11. The weight particles 4 consist of iron sand. Polyurethane is characterized by good flexibility and tear resistance, allowing it to adapt better to body movements while maintaining the structural stability of weight layer 3. The iron sand particles have a high density, enabling a high weight to be achieved in a small volume. At the same time, the particles can be evenly distributed to avoid excessive local weight and to increase the uniformity and stability of the weight.

[0037] A flexible cold storage layer 13 is positioned between the weight layer 3 and the inner waterproof layer 12. During exercise, the body generates heat, and the flexible cold storage layer 13 provides local cooling, helping to lower body temperature, reduce feelings of fatigue, and increase comfort during exercise.

[0038] The flexible cold storage layer 13 consists of cooling hydrogel. This material exhibits good flexibility and cold storage performance, can maintain a cooling effect during movement, and does not affect the overall performance or wearing comfort of the weight vest.

[0039] The remainder of embodiment 2 is identical to embodiment 1. The detailed description of the present application presented above uses specific examples to illustrate the principles and embodiments of the application. The explanations of the exemplary embodiments serve only to aid understanding of the application and its core idea. It should be noted that those skilled in the art in this technical field may, without deviating from the principles of this application, make a number of improvements and modifications which also fall within the scope of protection of the claims of the present application.
