Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing technology, specifically to a cuff structure for a windbreaker. Background Technology
[0002] Waterproof jackets are a common garment for outdoor climbers. During outdoor climbing, climbers frequently use their hands to ascend, swing ice axes, or grip rock holds, keeping the cuffs constantly facing upwards. Traditional waterproof jackets typically feature flat cuffs with Velcro closures, but this design has significant drawbacks in actual climbing scenarios: First, when the Velcro is tightened, the flat cuff doesn't fully conform to the wrist's natural curve, leaving gaps that allow rainwater to easily seep into the cuff, causing the arm to become wet and reducing comfort. In cold environments, this can even lead to hypothermia. Second, the tightened flat cuff can cause excess fabric to accumulate on the back of the hand, hindering wrist movement and power generation, severely impacting the climber's precise movements like swinging ice axes or gripping rock holds, increasing climbing safety risks.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a cuff structure for a windbreaker. Figure 1 This diagram shows a flattened state of the cuff structure (left hand) in an embodiment of the present invention. Figure 2This diagram illustrates the tightened state of the cuff structure (left hand) in an embodiment of the present invention. The cuff structure includes a cuff body, the edges of which have an arc-shaped concave edge 110 and an arc-shaped convex edge 120. The outer surface of the cuff body is provided with Velcro, which includes a mother strip 210 and a first daughter strip 220. The mother strip 210 is fixed to the cuff body as a whole; the base of the first daughter strip 220 is fixed to the cuff body, while the head of the first daughter strip 220 is free to move. The cuff body is spliced with… A folding portion 300 is provided, which is located between the base of the first sub-strip 220 and the end of the mother strip 210. The folding portion 300 is on the bonding path of the first sub-strip 220 and the mother strip 210. In the tightened state of the cuff body, the first sub-strip 220 is bonded to the mother strip 210, the arc-shaped concave edge 110 is bonded to the radial side surface of the outer side of the wrist, the arc-shaped convex edge 120 is bonded to the ulnar side surface of the outer side of the wrist, and the folding portion 300 is folded on the inner side of the wrist.
[0026] In the cuff structure of the rain jacket of this utility model, the edge of the cuff body has an arc-shaped concave edge 110 and an arc-shaped convex edge 120. This allows the cuff to fit closely to the physiological curve of the wrist when tightened, thereby reducing the existence of gaps and preventing rainwater from flowing into the cuff along the arm, avoiding the arm from getting wet. This significantly improves the wearing comfort of the rain jacket and reduces the risk of hypothermia. The cuff body is spliced with a folding part 300. When the cuff is tightened, the folding part 300 can automatically fold excess fabric on the inside of the wrist, avoiding the accumulation of fabric on the back of the hand and preventing it from hindering the flexible rotation and force exertion of the wrist. This ensures the automatic movement of the wrist and does not affect the climber's fine operations such as swinging an ice axe or gripping rock points, effectively improving the safety of climbing.
[0027] In some specific embodiments, please refer to Figure 1 The folding section 300 is internally fitted with several shape memory alloy shaping strips 310, which extend circumferentially along the wrist. These shape memory alloy shaping strips 310 guide the folding section 300 to fold and close naturally, allowing the fabric to accumulate neatly and orderly on the inner side of the wrist. This prevents the fabric from piling up on the back of the hand and hindering the flexible rotation and force exertion of the wrist, ensuring automatic wrist movement. It does not affect the climber's fine operations such as swinging an ice axe or gripping rock points, effectively improving the safety of climbing.
[0028] Figure 3The diagram illustrates the loose state of the cuff structure (left hand) in an embodiment of this utility model. The Velcro also includes a second sub-strip 230, the base of which is fixed to the cuff body, while the head of the second sub-strip 230 is free to move. The first sub-strip 220 is located on the bonding path between the second sub-strip 230 and the main strip 210. The second sub-strip 230 can cooperate with the first sub-strip 220 and the main strip 210 to establish a more stable and secure connection, ensuring that the Velcro will not come loose.
[0029] Specifically, the width of the mother strip 210 is L. 母 The width of the first sub-strip 220 is L1, and the width of the second sub-strip 230 is L2. 母 The constraint relationship between L1 and L2 is: L1 < L2 ≤ L 母 The first sub-strip 220 is narrower and has moderate adhesion, making it suitable for initially tightening the cuff. The second sub-strip 230 is wider and has stronger adhesion, allowing for further tightening of the cuff based on the first sub-strip 220, ensuring the cuff edge fits snugly against the wrist. The two sub-strips work together to ensure that the cuff completely covers the wrist after tightening, without gaps, effectively preventing rainwater from entering.
[0030] In some specific embodiments, please refer to Figure 3 An elastic tightening cord 400 is threaded through the edge of the cuff body. A portion of the elastic tightening cord 400 extends beyond the cuff body to form a pull section 410. An adjusting buckle 420 is provided on the pull section 410, avoiding the Velcro. The adjusting buckle 420 can control the tightness of the elastic tightening cord 400. When the elastic tightening cord 400 is tightened, the edge of the cuff body can be further tightened, working in conjunction with the tightening structure of the Velcro to make the entire cuff fit the wrist tightly from all directions, forming a waterproof and sealed structure.
[0031] Specifically, the elastic tightening rope 400 is made of a blend of Kevlar fiber and spandex, which has high strength, high elasticity and anti-aging properties.
[0032] In some specific embodiments, the concave depth of the arc-shaped concave edge 110 ranges from 4 to 6 mm, conforming to the physiological curve of the radial side surface of the lateral wrist. Optionally, the concave depth of the arc-shaped concave edge 110 can be 4 mm, 5 mm, or 6 mm. Preferably, the concave depth of the arc-shaped concave edge 110 is 4 mm, which is suitable for the physiological curve of the radial side surface of the lateral wrist of most people.
[0033] In some specific embodiments, the protrusion height of the arc-shaped convex edge 120 ranges from 4 to 6 mm, conforming to the physiological curve of the ulnar side surface of the outer wrist. Optionally, the protrusion height of the arc-shaped convex edge 120 can be 4 mm, 5 mm, or 6 mm. Preferably, the protrusion height of the arc-shaped convex edge 120 is 6 mm, which is suitable for the physiological curve of the ulnar side surface of the outer wrist in most people.
[0034] In some specific embodiments, the cuff body is a tubular structure made of waterproof, breathable, elastic, and abrasion-resistant fabric pieces, possessing excellent waterproofness, breathability, elasticity, and abrasion resistance. Specifically, the waterproof, breathable, elastic, and abrasion-resistant fabric piece uses GORE-TEX Pro nylon fabric with a waterproof index ≥28000mmH2O, a breathability index ≥20000g / m2 / 24h, good elasticity, and strong abrasion resistance, which can fully meet the needs of climbers.
[0035] In some specific embodiments, the Velcro is secured to the cuff body using double stitching, ensuring a firm and reliable fastening. Furthermore, the Velcro is made of high-strength, low-temperature-resistant outdoor-grade material, maintaining good adhesion even at -20°C.
[0036] In some specific embodiments, the arc-shaped concave edge 110 and the arc-shaped convex edge 120 conform to the physiological curve of the wrist, fully taking into account the movement trajectory and force direction of the wrist during climbing, and ensuring the free movement of the wrist.
[0037] The cuff structure of this utility model's windbreaker has the following effects:
[0038] (1) Excellent waterproof performance: Through the irregular pattern design - the combination of the arc concave edge 110 and the arc convex edge 120, the multi-layer Velcro and the elastic tightening cord 400, the cuff can fit tightly to the wrist when tightened, completely eliminating gaps, effectively blocking rainwater from flowing into the cuff, providing climbers with reliable protection in harsh weather conditions and reducing the risk of hypothermia.
[0039] (2) Excellent flexibility of movement: The excess fabric after the cuff is tightened is neatly and orderly folded and gathered on the inside of the wrist by the folding part 300, avoiding accumulation on the back of the hand; at the same time, combined with the elasticity of the fabric, it can minimize the obstruction of wrist movement, allowing climbers to freely perform fine operations such as swinging ice axes and gripping rock points, effectively improving climbing safety and efficiency.
[0040] (3) Good adaptability and durability: The multi-layer Velcro and elastic drawstring 400 adjustment structure can adapt to different users' wrist sizes; the abrasion-resistant fabric ensures that the cuffs are not easily damaged even after long-term use in frequent climbing activities and harsh environments, thus extending the service life of the jacket.
