Description

Technical Field

[0001] This invention relates to a grip accessory, and more particularly to a grip. Background Technology

[0002] Many products feature grip designs, such as jump rope handles, sports wrist straps, backpack handles, bicycle handlebars, and various handheld tools, to improve grip stability and comfort. However, most existing grips are rigid, resulting in a relatively poor feel. Prolonged use can lead to fatigue, and the grips tend to slip after sweating, affecting control and safety. While some grips are covered with elastic materials to improve the feel, their airtightness is relatively poor, resulting in poor internal air circulation and relatively poor breathability and sweat-wicking. Furthermore, during use, sweat does not evaporate easily and is easily absorbed by the elastic materials, which then dry slowly, keeping the grip damp for extended periods. This not only affects the grip feel, reducing comfort and stability, but also makes it easier for bacteria to grow.

[0003] In view of this, the inventor has conducted in-depth research on the above-mentioned problems, which led to the present invention. Summary of the Invention

[0004] The purpose of this invention is to provide a grip that has a relatively good feel, is not easy to slip, and has good breathability and sweat-wicking effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A grip includes an outer elastic tubular body and an inner elastic tubular body inserted within the outer elastic tubular body. One end of the outer elastic tubular body is integrally or fixedly connected to one end of the inner elastic tubular body, and the other end of the outer elastic tubular body is integrally or fixedly connected to the other end of the inner elastic tubular body. A breathable cavity is formed between the outer elastic tubular body and the inner elastic tubular body, and a plurality of first perforations communicating with the breathable cavity are provided on the outer elastic tubular body.

[0006] As an improvement of the present invention, the outer diameter of the outer elastic tubular body gradually decreases from its middle part to its two ends.

[0007] As an improvement of the present invention, the inner elastic tubular body is provided with a plurality of second perforations that are respectively connected to the air-permeable cavity.

[0008] As an improvement of the present invention, the number of the first perforation and the second perforation are the same and they are arranged in a one-to-one correspondence.

[0009] As an improvement of the present invention, the ventilated cavity is further provided with a plurality of elastic columns that are integrally connected to the outer elastic tubular body and the inner elastic tubular body respectively.

[0010] As an improvement of the present invention, the outer elastic tubular body, the inner elastic tubular body and the elastic column all include a plurality of lattice units connected together by 3D printing.

[0011] As an improvement of the present invention, the cell edge length of the lattice unit is 3mm-8mm, and the rod diameter of the lattice unit is 0.8mm-2mm.

[0012] As an improvement of the present invention, both the outer elastic tubular body and the inner elastic tubular body are arc-shaped.

[0013] As an improvement of the present invention, both the outer elastic tubular body and the inner elastic tubular body are polyurethane tubular bodies, TPU tubular bodies, or nylon tubular bodies.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects: 1. The grip provided by this invention uses an elastic tubular body, which provides a relatively good grip and can effectively buffer the impact force transmitted to the user's palm. At the same time, by forming a breathable cavity between the outer and inner elastic tubular bodies and opening multiple first perforations on the outer elastic tubular body, it is not only less prone to slipping, but also has good breathability. Sweat can be drained away in time through the perforations and breathable cavity, which greatly improves the breathability and sweat-wicking effect of the grip and makes it less prone to bacterial growth.

[0015] 2. By creating a second perforation, not only can the weight of the grip be reduced, but the drying speed of sweat during use can also be improved, further enhancing the grip feel.

[0016] 3. Thanks to 3D printing technology, the perforated areas in the grip can utilize a smoothly deformable lattice design, resulting in a superior feel and higher comfort. Furthermore, the 3D printing process allows for flexible adjustment of the perforation density, aperture, and grip surface curvature to suit different hand sizes, ensuring a perfect fit between the grip and the hand. Whether the user has large or small hands, they can enjoy a comfortable grip experience. At the same time, the perforated structure reduces the contact area between the grip and the hand, minimizing the stuffiness and discomfort caused by prolonged contact, further enhancing comfort.

[0017] 4. Since both the outer and inner elastic tubular bodies are arc-shaped, when sweat is produced on the palm, the sweat can converge at the end of the arc-shaped handle, preventing sweat from accumulating on the grip surface.

[0018] 5. The grip provided by this invention, through the synergistic effect of perforations, the gradual change in the outer diameter of the outer elastic tubular body, and the arc shape of the elastic tubular body, can improve the fit between the grip and the palm, providing better cushioning during gripping and avoiding local pressure. In particular, the arc-shaped structure design avoids sharp edges from pressing on the palm, and the gradual change in outer diameter design increases friction during gripping, which not only improves grip stability but also reduces local pressure during gripping, avoiding palm soreness caused by prolonged gripping. The perforated structure design allows the grip to have a large elastic deformation space. Compared with traditional solid grips, when the palm applies gripping force, the perforations can produce slight deformation, conforming to the force state of the palm, playing a cushioning role, dispersing gripping pressure, reducing arm fatigue, and adapting to the gripping needs of long-term running.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the terms "first," "second," etc., used in the present invention are used to distinguish different objects, rather than to describe a specific order.

[0022] This embodiment provides a grip that can be used on jump ropes, hand ropes, or backpack handles, and can also be used on bicycle handlebars. In this embodiment, the grip is used as an example of its application to a running rope.

[0023] like Figures 1-2As shown, the grip provided in this embodiment includes an outer elastic tubular body 10 and an inner elastic tubular body 20 inserted within the outer elastic tubular body 10. Both the outer elastic tubular body 10 and the inner elastic tubular body 20 are arc-shaped. One end of the outer elastic tubular body 10 is integrally or fixedly connected to one end of the inner elastic tubular body 20, and the other end of the outer elastic tubular body 10 is integrally or fixedly connected to the other end of the inner elastic tubular body 20. A breathable cavity is formed between the outer elastic tubular body 10 and the inner elastic tubular body 20. The outer elastic tubular body 10 has multiple first perforations 11 that communicate with the breathable cavity. The diameter of the first perforation 11 is preferably 2-5 mm. The inner diameter of the inner elastic tubular body 20 is constant and slightly smaller than the outer elastic tubular body 20. Before use, the outer diameter of the running rope is inserted into the inner elastic tubular body 20. The elasticity of the inner elastic tubular body 20 is used to bind the handle to the running rope, preventing the handle from moving relative to the running rope during use. During use, sweat from the palms can be quickly discharged through the first perforation 11, resulting in relatively good breathability and sweat-wicking properties. At the same time, the elastic inner elastic tubular body 20 can deform with the force changes of the running rope, which in turn moves the outer elastic tubular body 10, ultimately being perceived by the visually impaired person without affecting the traction and guidance function of the running rope. Meanwhile, the breathable cavity can also serve as a buffer space, effectively cushioning the traction force of the running person and preventing excessive traction force from affecting the running rhythm of the visually impaired runner. The feel is also relatively good.

[0024] Preferably, the outer diameter of the outer elastic tubular body 10 gradually decreases from its middle part to its two ends. In this embodiment, the outer diameter of the middle part of the outer elastic tubular body 10 is 16mm, and the outer diameter of its two ends is 10mm. This helps visually impaired people to quickly perceive the position of their hands on the handle, and also helps to improve the grip feel.

[0025] Preferably, the inner elastic tubular body 20 has multiple second perforations 21 that communicate with the ventilation cavity, which helps to reduce the weight of the grip. The number of first perforations 11 and second perforations 21 are the same and they are arranged in a one-to-one correspondence. Both are arranged in an array, which helps to improve the drying speed of the running rope at the grip and makes it easy to clean.

[0026] Preferably, the breathable cavity is further provided with multiple elastic columns 30, which are integrally connected to the outer elastic tubular body 10 and the inner elastic tubular body 20, respectively, to enhance structural strength. Both the outer elastic tubular body 10 and the inner elastic tubular body 20 are polyurethane tubular bodies, and the elastic columns 30 are polyurethane columns, possessing characteristics such as water resistance, bending resistance, impact resistance, non-absorbency, easy cleaning, and good biocompatibility. Of course, the outer elastic tubular body 10 and the inner elastic tubular body 20 can also be TPU tubular bodies or nylon tubular bodies. The outer elastic tubular body 10, the inner elastic tubular body 20, and the elastic column 30 are integrally formed by 3D printing. All three include multiple lattice units connected together by 3D printing. The lattice units can be Voronoi, BCC, FCC, Diamond, Octet, Kelvin, or Truncated structures. In this embodiment, Truncated lattice units are selected. The cell edge length of the lattice units is 3mm-8mm, and 5mm is selected in this embodiment. The rod diameter of the lattice units is 0.8mm-2mm. Different rod diameters will affect the hardness and feel. In this embodiment, 1mm is selected, which has the best feel and can reduce the weight to the lightest level while ensuring structural strength.

[0027] Before 3D printing, a 3D model needs to be created using software such as SolidWorks or UG. Topology optimization of the crystal structure is then performed, adjusting the shape, side length, porosity, and beam diameter of the lattice units to ensure a lightweight grip (total grip weight ≤ 10g). The model is then sliced ​​to generate the necessary slice files for 3D printing. The slice layers are set to a thickness of 0.1mm-0.2mm, preferably 0.2mm, to ensure surface precision and efficiency. After printing, the grip surface is polished using a polishing tool to remove layers and burrs, resulting in a smooth surface without sharp edges. Finally, the grip is cleaned and dried.

[0028] In addition, in this embodiment, one end of the outer elastic tubular body 10 is provided with a marking area, on which raised dots for forming Braille are provided, and the content of the Braille can be selected according to actual needs.

[0029] The grip provided in this embodiment adopts a 3D printing photopolymerization molding process. The hollow structure formed by perforation adopts a smoothly deformed Truncated cube lattice design. The hollow area accounts for 60%-70% of the overall volume of the grip, and the overall weight is about 7-8g. By precisely controlling the hole diameter and hole density, the amount of material used is reduced. At the same time, relying on the structural forming advantages of 3D printing, the core stress area of ​​the grip is preserved, and the structural strength is not reduced due to hollowing.

[0030] The grip structure provided in this embodiment is not a single through-type design, but rather a three-dimensional hollow layout of "axial connection + normal penetration". The outer layer has 11 connecting channels along the curvature of the grip, while gradually elliptical holes are set along the normal direction of the curved surface, achieving an elliptical gradient from the hand contact surface to both ends. The inner layer, fitted to the outer layer's axial channels, has the same number of elongated elliptical lattice holes. These holes are connected to the axial penetration channels via lattice rods, forming a complete airflow circulation channel. The advantage of this structure is that, during running, regardless of the grip posture, the axial penetration channel allows for bidirectional airflow, while the hollow holes connect the air between the palm and grip contact surface with the outside air. This overcomes the drawback of traditional solid grips where the "palm-grip contact surface is sealed, with no airflow exchange," achieving air circulation in the grip area, effectively improving the grip's breathability, avoiding the stuffiness of the palm caused by prolonged gripping, and meeting the needs of long-term running scenarios.

[0031] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
