Description

Technical Field

[0001] This application relates to the field of protective equipment technology, and in particular to a built-in palm guard for ski gloves. Background Technology

[0002] The core purpose of adding palm guards or wrist braces to ski gloves is to address the risk of wrist injuries during skiing, especially since beginners' instinctive hand-to-wrestle action when falling can easily lead to radial fractures or wrist sprains. Wrist braces use built-in rigid materials to limit excessive wrist flexion and distribute point impact force across the entire palm and forearm, thereby reducing the probability of injury.

[0003] In related technologies, the industry currently generally adopts the following three solutions for ski glove wrist protectors: First, using rigid plastic plates such as ABS to restrict wrist flexion through rigid support; second, using smart cushioning materials such as D3O to absorb impact by relying on non-Newtonian fluid properties; and third, using a composite structure of metal plates and EVA foam to balance strength and lightweight. All of the above solutions achieve force dispersion by being built into the area from the palm to the wrist.

[0004] Existing built-in palm guards have the following problems: flat or single-curvature designs excessively restrict the wearer's wrist flexion, extension, and rotation freedom, and interfere with actions such as gripping ski poles and turning, thus seriously affecting wearing flexibility and comfort. Utility Model Content

[0005] To improve wearing flexibility and comfort, this application proposes a built-in palm guard for ski gloves.

[0006] The technical solution proposed in this application for a built-in shank guard for ski gloves is as follows: A built-in palm guard for ski gloves includes a palm guard body, which is composed of a protective outer layer and a cushioning inner layer. The palm guard body is divided into a middle arch section in the horizontal direction by a complex curvature design, and a first end arch section and a second end arch section respectively set at both ends of the middle arch section. The middle arch section is set with a positive curvature and conforms to the arc of the wrist. The first end arch section and the second end arch section are set with a negative curvature and respectively conform to the palm and the radius arc of the human hand.

[0007] By adopting the above technical solutions, a stable support surface is formed, which limits excessive bending of the wrist joint, reduces the risk of radial fracture or sprain, and the structural design fits the wrist better, conforms to human factors engineering, and improves wearing flexibility and comfort while taking into account protection.

[0008] Preferably, the two sides of the intermediate arch section curve upwards and are higher than the central region of the intermediate arch section.

[0009] By adopting the above technical solution, the two sides of the middle arch section curve upward to form a bridge-like structure. By increasing the support height of the radius to pubic region, a more stable mechanical framework is formed, effectively dispersing the impact force during movement.

[0010] Preferably, the intermediate arch section is thickened and the maximum thickness does not exceed 9mm.

[0011] By adopting the above technical solution, the upper limit of the thickness of the middle arch section can be precisely controlled. While ensuring the core protection strength, the weight can be effectively reduced compared with traditional wristbands, thereby reducing friction and pressure during exercise.

[0012] Preferably, a bulge-shaped protrusion is provided in the middle of the first end arch section corresponding to the protruding part of the carpal bone.

[0013] By adopting the above technical solution, the contact surface is increased to reduce the local pressure on the wrist bone and to keep it in stable contact during wrist flexion and extension movements.

[0014] Preferably, the protective outer layer and the buffer inner layer are bonded and fixed together by a millimeter-level concave-convex structure.

[0015] By adopting the above technical solution, the mechanical interlocking effect is used to achieve physical anchoring of the two layers of materials, thereby improving the peel strength.

[0016] Preferably, the outer protective layer is made of PE composite material, and the inner buffer layer is made of polymer material.

[0017] By adopting the above technical solutions, wear resistance and cushioning capacity can be improved.

[0018] Preferably, the protective outer layer has two reinforcing ribs integrally formed by injection molding at the position corresponding to the second end arch section. The two reinforcing ribs are arranged at intervals and extend away from the radial end of the human hand.

[0019] By adopting the above technical solution, a parallel support structure is formed, which can effectively resist the bending stress generated by the wrist dorsiflexion movement during skiing and reduce the plastic deformation of the main body of the hand guard in the arched area at the second end.

[0020] Preferably, a ski glove includes a built-in palm guard for ski gloves, and also includes a glove body. Inside the glove body, a cloth bag with a length and width adapted to the palm guard body is provided, and the palm guard body is naturally inserted and fixed in the cloth bag.

[0021] By adopting the above technical solutions, the occurrence of hand guards shifting or rotating during skiing can be reduced, and the protective position can always be aligned with the key stress areas of the palm.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The main body of the palm guard forms a stable support surface by splicing together a protective outer layer and a buffer inner layer, which limits excessive bending of the wrist joint, reduces the risk of radial fracture or sprain, and the structural design fits the wrist better, conforms to ergonomics, and improves wearing flexibility and comfort while taking into account protection. 2. The upward curves on both sides of the middle arch section form a bridge-like structure, which increases the support height from the radius to the pubic bone, forming a more stable mechanical framework and effectively dispersing the impact force during movement; 3. Improved the wear resistance and cushioning capacity of the equipment. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] Example 1 This application discloses a built-in palm guard for ski gloves. (See also...) Figure 1-2 A built-in palm guard for ski gloves includes a palm guard body 1, which is composed of a protective outer layer 11 and a cushioning inner layer 12. The palm guard body 1 is divided into a middle arch section 2 and a first end arch section 3 and a second end arch section 4 respectively located at both ends of the middle arch section 2 through a complex curvature design. The middle arch section 2 is set with a positive curvature and conforms to the arc of the wrist, while the first end arch section 3 and the second end arch section 4 are set with a negative curvature and respectively conform to the palm and the radius arc of the human hand.

[0029] Correspondingly, the protective outer layer 11 and the buffer inner layer 12 are spliced ​​together to form a stable support surface, dispersing the point impact force during a fall to the entire palm and forearm, thereby reducing local pressure; the positive curvature design of the middle arch section 2 conforms to the wrist curvature, which can limit excessive bending of the wrist joint; the reverse curvature design of the first end arch section 3 and the second end arch section 4 respectively supports the palm and radius, reducing the risk of radius fracture or sprain.

[0030] In summary, this equipment features a complex curvature design with a three-arch structure to adapt to the natural shape of the hand, conforming to ergonomics. It maintains a close fit during skiing movements, reducing the risk of slippage leading to protection failure, and improving both protection and wearing flexibility and comfort.

[0031] Specifically, the two sides of the middle arch section 2 curve upwards and are higher than the middle area of ​​the middle arch section 2, forming a bridge-like structure. This increases the support height in the radius to ulna area and provides a larger area of ​​vulnerable parts with local support compared to traditional wrist braces, reducing the risk of complex injuries.

[0032] Furthermore, this structural design creates a more robust mechanical framework, effectively dispersing the impact force during movement and maintaining structural stability during wrist movement, reducing the risk of brace displacement or deformation.

[0033] On the other hand, in this embodiment, the middle arch section 2 is thickened and the maximum thickness is only 8.7mm. By precisely controlling the upper limit of the thickness of the middle arch section 2, the thickness limitation makes the main body of the palm guard plate 1 fit the natural shape of the hand more closely, reducing friction and pressure during movement. While ensuring the core protection strength, it effectively reduces the weight by about 30% compared with the traditional 14mm thick wrist guard plate, directly improving the wearing flexibility and freedom of hand movement, which is especially suitable for long-term skiing scenarios.

[0034] Furthermore, the thickened treatment focuses on strengthening the central arch section with positive curvature, which is a key stress area of ​​the wrist. Combined with the thinner reverse curvature arch sections at both ends, it forms a gradient support structure, which not only disperses the impact force but also eliminates the stiffness caused by the excessive thickness of traditional wrist braces.

[0035] Meanwhile, the first end arch section 3 has a bulge-shaped protrusion 31 in the middle corresponding to the protruding part of the carpal bone. By increasing the contact area, the local pressure of the carpal bone is reduced, and the stress concentration caused by the planar design of traditional wrist guards is reduced. This allows the wrist to maintain a stable fit during flexion and extension movements, reducing the risk of protection failure caused by slippage of the protective gear. It is especially suitable for high-frequency wrist fine-tuning movements during skiing.

[0036] Furthermore, by matching the height of the bulge with the wrist bone protrusion, sufficient buffer space is reserved, and the transition curvature of the protrusion edge is used to guide the impact force to the palm plate body, forming a force transmission path that is more in line with human factors engineering.

[0037] Corresponding to the above process, in this embodiment, a large area of ​​shallow depression is formed in the middle of the upper surface of the inner buffer layer 12, and a sheet-like protrusion is integrally formed on the lower surface of the outer protective layer 11 corresponding to the depression. The sheet-like protrusion and the shallow depression are engaged to form a 0.3mm concave-convex structure 13, which bonds and fixes the outer protective layer 11 and the inner buffer layer 12. The mechanical interlocking effect is used to achieve physical anchoring of the two layers of materials, improve the peel strength, and ensure the synchronization of the outer protection and the inner buffer during violent movement.

[0038] Furthermore, the concave-convex curvature design allows the two layers of material to produce slight relative displacements when subjected to force, which maintains the overall structural stability and can adapt to the deformation requirements of multi-angle wrist movements, reducing motion interference caused by traditional rigid bonding.

[0039] Specifically, the outer protective layer 11 is made of PE composite material, which has high wear resistance and tear resistance, effectively resisting the scratches and impacts of hard objects such as skis and ski poles. Its hydrophobic properties can also prevent snow water penetration and keep the inside dry. Meanwhile, the inner buffer layer 12 is made of polymer material, which can cause the material molecules to contract and harden when subjected to external impact through slow rebound. After the impact force is removed, the molecular structure gradually recovers and softens under thermodynamic drive, converting the impact kinetic energy into heat energy that is not felt by the human body and dissipating it, reducing the occurrence of material hardening and resulting in a decrease in protective performance in low-temperature environments.

[0040] Furthermore, the rigid protection of the outer PE layer and the flexible cushioning of the inner polymer layer complement each other, forming a "hard-soft" gradient structure. This structure can resist external impacts and mitigate residual vibrations transmitted to the wrist through the deformation of the inner layer. The difference in the coefficients of thermal expansion between the two materials (PE approximately 200 × 10⁻⁻⁴) is significant. 6 / ℃, polymer approximately 50-150×10⁻ 6 ( / ℃) It can maintain interface stability under extreme temperature differences, reducing the risk of delamination or deformation.

[0041] On the other hand, the protective outer layer 11 has two reinforcing ribs 41 integrally formed by injection molding at the position corresponding to the second end arch section 4. The two reinforcing ribs 41 are arranged at intervals and extend away from the radial end of the human hand to form a parallel support structure. This can effectively resist the bending stress generated by the wrist dorsiflexion movement during skiing, reduce the plastic deformation of the palm guard body 1 in the area of ​​the second end arch section 4, and the extension direction of the reinforcing ribs 41 is consistent with the force transmission path during wrist movement. This can guide the impact force from the radial end to the palm guard body 1, reduce the concentration of stress in the transition area between the arch section and the plane, and extend the structural life.

[0042] Furthermore, compared to a solid structure, the spaced double-rib design, while maintaining lightweight, enhances the torsional resistance of the main body 1 of the hand guard plate when the wrist swings laterally by forming local rigid areas, reducing the risk of accidental deformation when gripping ski poles.

[0043] The implementation principle of the built-in palm guard for ski gloves in this application embodiment is as follows: The equipment forms a stable support surface by bonding the concave and convex structure 13 between the protective outer layer 11 and the buffer inner layer 12, which disperses the point impact force when falling to the entire palm and forearm, reducing local pressure; it also presents a three-arch structure through a complex curvature design to restrict and support the wrist joint, palm and radius, reducing the risk of fracture or sprain. The equipment adapts to the natural shape of the hand, conforms to ergonomics, and can stay in close contact during skiing, reducing the occurrence of slippage that leads to protection failure. It improves wearing flexibility and comfort while taking into account protection.

[0044] Example 2 This application discloses a ski glove. (Refer to...) Figure 3 The invention includes a built-in palm guard for ski gloves and a glove body 5. In this embodiment, a matching cloth bag 51 is provided inside the glove body 5 to correspond to the palm guard body 1, which has a length and width of 125.84 mm and 46.63 mm, respectively. The palm guard body 1 is naturally inserted and fixed in the cloth bag 51, and is aligned and conforms to the curve of the human hand. The material of the cloth bag 51 allows the palm guard body 1 to undergo slight deformation when subjected to force, which can both buffer the instantaneous pressure of skiing impact and prevent excessive displacement from affecting the protective effect, thus achieving the dual function of "fixation-buffering".

[0045] Furthermore, in this embodiment, the second end arch section 4 of the palm protector body 1 is provided with a waist-shaped opening 42 for passing through and fixing the webbing, so that the user can take the palm protector body 1 out of the cloth bag 51 by pulling, realizing the quick disassembly of the palm protector body 1. The user can wash the glove body 5 separately or replace the new palm protector body 1, improving the flexibility and convenience of product use.

[0046] The implementation principle of a ski glove in this application embodiment is as follows: the equipment adds a cloth bag 51 with a length and width that is adapted to the glove body 5 to ensure that the palm guard body 1 is rigidly connected to the glove body 5 after insertion, thereby reducing displacement or rotation during skiing and keeping the protective position always aligned with the key force area of ​​the palm.
