Description

Technical Field

[0001] This utility model relates to waist belts, and more particularly to a soft and comfortable waist belt. Background Technology

[0002] Waist trainers are mainly used to bind the waist during daily activities or sports. They can provide stable support for the waist tissues, restrict excessive waist movement, effectively distribute pressure, and prevent waist injuries caused by excessive resistance exercise and high-intensity muscle load during exercise. In many cases, women also use waist trainers to bind their waists for shaping purposes, which requires waist trainers to be particularly soft and comfortable.

[0003] Currently, most waist trainers are made by bonding two pieces of fabric together. The fabric is typically made of spandex or rubber, which provides some support and compression, helping to reduce pressure on the waist. Common bonding methods fall into two main categories: one uses a single sheet of adhesive film for pressing, using high temperature and pressure to tightly bond the film to the fabric. While this method ensures high bonding strength between the fabrics, the adhesive film cannot penetrate into and be absorbed by the fabric layer. This results in a significant increase in the overall thickness and stiffness of the waist trainer. Viewed from the side, a three-layered structure consisting of a fabric layer, an adhesive layer, and another fabric layer can be clearly seen. This also greatly reduces the product's elasticity, leading to problems in actual use. Users will clearly feel the excessive constriction of the waist trainer, which restricts the body's natural movement, especially when performing large bending or twisting movements, this discomfort is more pronounced. Another type of bonding method uses silicone glue, but because the fabric is made of spandex or rubber, a thick silicone layer is often required to ensure a strong bond. The side of the product still shows a clear three-layer structure. During wear, due to the presence of multiple layers, the comfort and breathability of the waist trainer are greatly reduced, and the user's waist is prone to stuffiness and dampness. At the same time, the poor elasticity and extensibility cannot adapt to the dynamic changes of the waist during human movement, making it difficult to provide continuous and effective support and protection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a soft and comfortable waist belt. This soft and comfortable waist belt is thin, breathable and stretchy, and is softer and more skin-friendly when worn, providing good comfort and effective continuous support and protection.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] A soft and comfortable waist trainer includes a waist trainer body with matching first connecting portions at both ends. The waist trainer body includes an outer fabric layer, an inner fabric layer, and an adhesive layer. The outer fabric layer and the inner fabric layer are bonded together by the adhesive layer. The waist trainer body is characterized by: both the outer fabric layer and the inner fabric layer being made of double-layer knitted fabric; the adhesive layer being formed by applying PUR adhesive to the outer fabric layer or the inner fabric layer by brushing; the thickness of the adhesive layer being 0.5-0.8 mm; and the outer fabric layer and the inner fabric layer being tightly adhered together after being bonded by the adhesive layer. The soft and comfortable waist trainer also includes a pressure band, the middle of which is bonded to the middle of the outer surface of the outer fabric layer by PUR adhesive, and the pressure band being arranged along the length of the waist trainer body. The two ends of the pressure band are respectively provided with second connecting portions matching the first connecting portions.

[0007] In the aforementioned soft and comfortable waist trainer, the adhesive layer is formed using PUR adhesive, with a thickness of only 0.5-0.8mm. Two double-layer knitted fabrics replace traditional spandex or rubber, allowing the double-layer knitted fabrics to absorb the adhesive during heat pressing and achieve a tight bond through mutual penetration. This results in a thinner waist trainer (from the side, the two double-layer knitted fabrics almost merge into one piece, with no visible boundary, eliminating the appearance of a thick adhesive layer). Furthermore, due to the high bonding strength, good elasticity, and high-temperature resistance of PUR adhesive, a thicker application can be applied to stretching areas requiring enhanced elasticity, while a single layer or spot application can be used at other connection points. This ensures a tight bond between the two fabric layers, effectively guaranteeing the adhesive strength between the outer and inner fabric layers and improving the elasticity of the waist trainer. It also ensures the waist trainer can withstand 100℃ washing without delamination. In addition, a pressure band provides even stronger restraint; the pressure band, also bonded to the outer fabric layer with PUR adhesive, offers the same advantages. The adhesive layer of this soft and comfortable waist trainer can penetrate directly into the knitted fabric layer, thereby reducing the overall thickness of the waist trainer and improving its elasticity. It also makes the fabric layers bond more tightly, resulting in a softer, more skin-friendly feel and better comfort when worn. Simultaneously, it ensures that the waist trainer is not obstructed by the adhesive layer, effectively improving breathability. Typically, pressure belts are also made of two pieces of double-layered knitted fabric bonded together with PUR adhesive.

[0008] The aforementioned inside and outside directions are determined by the position of the waist belt when it is worn. The side closer to the user's body is the inside, and the side farther away from the user is the outside.

[0009] The first and second connecting parts mentioned above generally use Velcro. Typically, the inner side of one end of the inner material layer is provided with a Velcro clasp, the outer side of both ends of the outer material layer is provided with a Velcro clasp, and the inner side of both ends of the pressure belt is provided with a Velcro clasp.

[0010] In a preferred embodiment, the soft and comfortable waistband further includes two side support pieces, which are tightly sandwiched between the outer fabric layer and the inner fabric layer, and the two side support pieces correspond to the positions of the two sides of the lumbar spine.

[0011] In another preferred embodiment, the soft and comfortable waistband further includes a waist support piece and two side waist support pieces, which are tightly sandwiched between the outer fabric layer and the inner fabric layer, respectively. The waist support piece corresponds to the position of the lumbar spine, and the two side waist support pieces correspond to the positions of the two sides of the lumbar spine.

[0012] For those who don't require strong support, a waist trainer without any support pads between the outer and inner fabric layers can be chosen. In this case, the support provided is limited, but the waist trainer offers better breathability and elasticity. For those who need some support, a waist trainer with two side support pads can be chosen, providing support to both sides of the lumbar spine when worn. For those who need even stronger support, a waist trainer with both lumbar support pads and side support pads can be chosen, further enhancing the support for the lower back when worn.

[0013] In a further preferred embodiment, the adhesive layer is applied in dots on the outer or inner fabric layer at the position corresponding to the waist support piece or side support piece to form a placement area. Typically, when applying the adhesive, a dot-applied method can be used to create a placement area on the fabric layer for the support piece. No adhesive is applied within the placement area, and the dotted adhesive is dense, thus directly sealing the support piece when the fabric is bonded. This eliminates the need to pre-leave or sew out a placement cavity, ensuring that the support piece will not move during wear and cause the fabric to be punctured.

[0014] In a further preferred embodiment, both the lumbar support plate and the lumbar side support plate are made of plastic.

[0015] In a preferred embodiment, the soft and comfortable waist trainer also includes a reinforcing fabric piece. The reinforcing fabric piece is positioned along the width of the waist trainer body, spanning both the waist trainer body and the pressure band. The reinforcing fabric piece is bonded to the outer surface of the outer fabric layer and the pressure band using PUR adhesive. The reinforcing fabric piece enhances the connection strength between the pressure band and the waist trainer body, preventing the pressure band from being torn off during use.

[0016] In a preferred embodiment, a long, narrow dividing hole extending along the length direction is provided at the middle position of the pressure belt. The long, narrow dividing hole improves the ductility of the pressure belt when stretched in all directions.

[0017] In a preferred embodiment, the waist belt body has multiple ventilation holes.

[0018] The beneficial effects of this utility model are as follows: this soft and comfortable waist belt is thin, breathable and stretchy, softer and more skin-friendly when worn, and provides good comfort and effective continuous support and protection. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Example 1, as Figure 1-2 The waist belt shown includes a waist belt body 1 and a pressure belt 2. The waist belt body 1 has matching first connecting parts 3 at both ends. The waist belt body 1 includes an outer fabric layer 101, an inner fabric layer 102, and an adhesive layer. Both the outer fabric layer 101 and the inner fabric layer 102 are made of double-layer knitted fabric. The adhesive layer is formed by applying PUR adhesive to the outer fabric layer 101 or the inner fabric layer 102 by brushing. The thickness of the adhesive layer is 0.5-0.8mm. The outer fabric layer 101 and the inner fabric layer 102 are tightly adhered together after being bonded by the adhesive layer. The middle position of the pressure belt 2 is bonded to the middle position of the outer side of the outer fabric layer 101 by PUR adhesive. The pressure belt 2 is set along the length direction of the waist belt body 1. The two ends of the pressure belt 2 are respectively provided with second connecting parts 4 that match the first connecting parts 3.

[0025] In the aforementioned soft and comfortable waist belt, the adhesive layer is formed by brushing PUR adhesive, with a thickness of only 0.5-0.8mm. Two double-layer knitted fabrics are used instead of traditional spandex or rubber. Therefore, the double-layer knitted fabrics absorb the adhesive during the heat-pressing process and achieve a tight bond through mutual penetration during bonding, resulting in a thinner waist belt body 1 (from the side, the two double-layer knitted fabrics almost merge into one piece, with no obvious boundary, and no thick adhesive layer). Simultaneously, due to the high bonding strength, good elasticity, and high-temperature resistance of PUR adhesive, a thicker application can be made to the stretching areas requiring enhanced elasticity, while a single layer or spot application can be applied to other connecting areas. This ensures a tight bond between the two fabric layers, effectively guaranteeing the adhesive strength between the outer fabric layer 101 and the inner fabric layer 102, while also improving the elasticity of the waist belt body 1. Furthermore, it ensures that the waist belt body 1 can withstand 100℃ water washing without delamination. Building upon this, the pressure band 2 provides even stronger binding force. The pressure band 2, also bonded to the outer surface of the outer fabric layer 101 with PUR adhesive, offers the same advantages. This soft and comfortable waistband's adhesive layer can directly penetrate into the knitted fabric layer, thereby reducing the overall thickness of the waistband and improving its elasticity. It also makes the fabric layers more tightly bonded, resulting in a softer, more skin-friendly, and more comfortable waistband to wear. Simultaneously, it ensures the waistband is not obstructed by the adhesive layer, effectively improving breathability.

[0026] The aforementioned inside and outside directions are determined by the position of the waist belt when it is worn. The side closer to the user's body is the inside, and the side farther away from the user is the outside.

[0027] The first connecting part 3 and the second connecting part 4 mentioned above adopt Velcro. The inner side of one end of the inner side material layer 102 is provided with Velcro fastener, and the outer side of both ends of the outer side material layer 101 is provided with Velcro fastener. The inner side of both ends of the pressure belt 2 is provided with Velcro fastener.

[0028] The soft and comfortable waist trainer also includes a reinforcing fabric piece 5, which is positioned along the width of the waist trainer body 1. The reinforcing fabric piece 5 spans the waist trainer body and the pressure band 2, and is bonded to the outer side of the outer fabric layer 101 and the pressure band 2 with PUR adhesive. The reinforcing fabric piece 5 enhances the connection strength between the pressure band 2 and the waist trainer body, preventing the pressure band 2 from being torn off during use.

[0029] A long, narrow dividing hole 201 extending along the length direction is provided in the middle of the pressure belt 2. The long, narrow dividing hole 201 can improve the ductility of the pressure belt 2 when stretched in all directions.

[0030] The waist belt body 1 has multiple ventilation holes 103.

[0031] Example 2, the difference between this example and Example 1 is as follows: Figure 3 As shown, the soft and comfortable waist trainer also includes two side support plates 6, which are tightly sandwiched between the outer fabric layer and the inner fabric layer, and the two side support plates 6 correspond to the positions on both sides of the lumbar spine. The waist trainer with two side support plates 6 can provide a certain degree of support strength, and when worn, the side support plates 6 can support both sides of the lumbar spine.

[0032] At the position corresponding to the waist support piece 6, the adhesive layer is applied in dots to form a placement area on the outer or inner fabric layer. When applying the adhesive, a dotted application method can be used to create a placement area on the fabric layer for the support piece. No adhesive is applied within the placement area; the dotted adhesive is dense, allowing the support piece to be directly sealed when the fabric is bonded. This eliminates the need to pre-leave or sew out a placement cavity, ensuring the support piece will not move during wear and cause the fabric to be punctured.

[0033] The lumbar support plate 6 is made of plastic.

[0034] Example 3, the difference between this example and Example 1 is as follows: Figure 4 As shown, the soft and comfortable waist belt also includes a waist support plate 7 and two side waist support plates 6. The waist support plate 7 and the two side waist support plates 6 are tightly sandwiched between the outer fabric layer and the inner fabric layer, respectively. The waist support plate 7 corresponds to the position of the lumbar spine, and the two side waist support plates 6 correspond to the positions of the two sides of the lumbar spine.

[0035] A waist belt with both a lumbar support plate 7 and a side lumbar support plate 6 can provide stronger support, thereby further enhancing the waist support when worn.

[0036] At the positions corresponding to the waist support piece 7 or the side waist support piece 6, the adhesive layer is applied in dots to form a placement area on the outer or inner fabric layer. When applying the adhesive, a dotted application method can be used to create a placement area on the fabric layer for the support piece. No adhesive is applied within the placement area; the dotted adhesive is dense, allowing the support piece to be directly sealed when the fabric is bonded. This eliminates the need to pre-leave or sew out a placement cavity, ensuring that the support piece will not move during wear and cause the fabric to be punctured.

[0037] Both the side waist support plate 6 and the waist support plate 7 are made of plastic.
