Description

Technical Field

[0001] This invention relates to a backpack and vest interchangeable cushion structure, and more particularly to a backpack and vest interchangeable cushion structure with better heat dissipation and sweat wicking function. Prior Technology

[0002] Note that backpacks and vests are commonly used clothing and accessories, but they also come into frequent contact with the human body, thus requiring cushions for cushioning. Most backpack and vest cushions are directly integrated with the backpack or vest. In order to solve the problem of stuffiness and sweating, these cushions increase their breathability, which also greatly increases their water permeability. The user's sweat will be absorbed into these cushions, which over time become a breeding ground for bacteria and mold, causing the cushions to emit a bad odor. If the cushions are integrated with the backpack or vest, they are not easy to clean. Therefore, if the cushions are replaceable and can be washed separately, they would be more convenient to use. In addition, the heat dissipation and sweat wicking function of the cushions also needs to be improved for greater comfort.

[0003] Therefore, the inventor, in view of this, conceived the idea of ​​invention, and designed it based on many years of experience. After extensive research, sample testing, and numerous revisions and improvements, the inventor finally launched this invention. Summary of the Invention

[0004] The main objective of this invention is to solve the above-mentioned problems and to provide a backpack / vest replaceable cushion structure.

[0005] To achieve the aforementioned objectives, the present invention provides a replaceable backrest structure for backpacks and vests, comprising a replaceable backrest, wherein the replaceable backrest includes a first surface layer, an inner pad, and a second surface layer, the first surface layer and the second surface layer are combined, and the inner pad is wrapped between the first surface layer and the second surface layer. The first surface layer is a moisture-wicking knitted mesh fabric, the inner pad is a polyester fiber knitted mesh fabric, the inner pad has two honeycomb-shaped inner pad surface layers, and an elastic support layer is provided between the two inner pad surface layers. The support layer is woven from polyester fiber monofilaments and has a thickness of more than 1 mm. The second surface layer is provided with at least one hook and loop fastener for quick fastening and fixing. The replaceable backrest is quickly fastened to a backpack or vest through the hook and loop fastener.

[0006] The main objective of this invention is that the first surface layer is a moisture-wicking knitted mesh fabric that absorbs sweat from the body, reducing user discomfort. Because the support layer is made of monofilament, it is strong and breathable. Combined with the honeycomb-shaped inner pad surface layer, it significantly increases the breathable area, aiding sweat evaporation. Furthermore, the support layer, also made of monofilament and with a thickness of over 1 mm, provides elasticity to reduce weight, making the replaceable cushion not only lightweight and elastic but also preventing water from further penetrating the inner pad and causing premature evaporation, thus maintaining comfort for the person in contact with the replaceable cushion. The replaceable cushion can be quickly attached to a backpack or vest using the hook and loop fastener, allowing the user to easily replace and wash the cushion to maintain hygiene.

[0007] Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description and the accompanying drawings. Simple Explanation of the Diagram

[Figure 3] is an exploded view of the present invention. Figure 4 is a cross-sectional view of the present invention. Figure 5 is a schematic diagram of the present invention in use. Figure 6 is a perspective view of the present invention used on a vest. Implementation

[0009] To enable your review committee to have a better understanding of the purpose, features, and effects of this invention, the following is a detailed description in conjunction with the accompanying drawings:

[0010] As shown in Figures 1 to 4, the present invention provides a replaceable backrest structure for a backpack vest, which includes a replaceable backrest (10). The replaceable backrest (10) includes a first outer layer (11), an inner pad (12), and a second outer layer (13). The first outer layer (11) is combined with the second outer layer (13), and the inner pad (12) is wrapped between the first outer layer (11) and the second outer layer (13). The first outer layer (11) is a moisture-wicking knitted mesh fabric, and the inner pad (12)... It is a polyester fiber knitted mesh fabric. The inner pad (12) has two honeycomb-shaped inner pad surface layers (121). An elastic support layer (122) is provided between the two inner pad surface layers (121). The support layer (122) is woven from polyester fiber monofilament and has a thickness of more than 1 mm. The second surface layer (13) is provided with at least one hook and loop fastener (131) for quick hook and loop fastening. As shown in Figure 6, the replaceable cushion (10) can be quickly hooked and looped onto a backpack (20) or a vest (30) through the hook and loop fastener (131).

[0011] The hook and loop fastener (131), also known as Velcro, can be either a loop or a hook side. The backpack (20) or the vest (30) can be quickly fastened to the hook and loop fastener (131) by simply setting the corresponding hook or loop side in advance.

[0012] Under a wicking test at a temperature of 20±2℃ and a relative humidity of 65±2RH for 10 minutes, the first surface layer (11) can reach a water rise height of 143 mm in the longitudinal direction and 132 mm in the transverse direction, which has a fairly fast fabric water absorption speed and can effectively help to absorb moisture and wick away perspiration.

[0013] The present invention provides a backpack vest replaceable cushion structure, wherein the replaceable cushion (10) is a square cushion body.

[0014] The present invention provides a backpack vest replaceable cushion structure, wherein the inner cushion surface layer (121) is woven with double-strand yarn and has better toughness.

[0015] The present invention provides a backpack vest replaceable cushion structure, wherein the first surface layer (11) and the second surface layer (13) are joined together by stitching.

[0016] As shown in Figure 5, through the above structure, the first surface layer (11) is a moisture-wicking knitted mesh fabric that absorbs sweat from the human body, reducing user discomfort. Since the support layer (122) is woven from monofilaments, it has high strength and good breathability. Combined with the honeycomb-shaped inner padding surface layer (121), it can significantly increase the breathable area and help sweat evaporate. Furthermore, the support layer (122) is woven from monofilaments and has a thickness of more than 1 mm, which can generate elasticity to reduce the load. The replaceable cushion (10) is not only lightweight and elastic, but also prevents water from further penetrating the inner pad (12) and evaporating early, keeping the human body in contact with the replaceable cushion (10) comfortable. The replaceable cushion (10) can be quickly attached to the backpack (20) or the vest (30) via the hook and loop fastener (131), so that the user can easily replace the replaceable cushion (10) and wash it to maintain hygiene.

[0017] In actual use, when the user wears the backpack (20) or the vest (30), the body is supported and cushioned by the replaceable cushion (10). The replaceable cushion (10) has the effect of absorbing moisture and wicking away sweat and is breathable to help sweat evaporate, making the body more comfortable. The hook and loop fastener (131) can be fastened quickly and can also be quickly removed to replace or wash the replaceable cushion (10), which can prevent the absorbed sweat from producing odors and the growth of bacteria and mold, thereby improving hygiene.

[0018] The above description is merely one preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention; that is, all equivalent changes and modifications made in accordance with the claims of the present invention should still fall within the scope of the present invention.

[0019] This invention includes: (10): Replaceable cushion (11): First surface layer (12): Inner padding (121): Inner lining surface (122): Support layer (13): Second surface layer (131): Hook and loop fasteners (20): Backpack (30): Vest
