Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grip wrapping, and particularly relates to a reusable injection-molded spiral grip wrap with an efficient fixing structure and high-quality material properties. It is suitable for the grip parts of indoor and outdoor sports equipment and various sports devices, such as fishing rods, rackets, clubs, and vehicle grips for anti-slip, shock absorption, and protection, and is detachable and reusable. Background Technology
[0002] In both indoor and outdoor sports and everyday use of sports equipment, such as fishing rods, badminton rackets, table tennis rackets, tennis rackets, and golf clubs, as well as vehicles like bicycles and motorcycles, users need to grip handles or grips to perform control actions. To ensure grip stability and comfort, prevent slippage, and improve the durability and shock absorption of the equipment, handlebar wrapping is widely used in these grip areas.
[0003] Traditional handle wrapping tape currently on the market faces numerous problems during actual wrapping. Firstly, the wrapping method relies on manual application of force. Excessive force can easily cause tearing, deformation, and other damage, severely impacting product lifespan. Insufficient force prevents the tape from adhering tightly to the grip area, leading to loosening and shifting during use, resulting in reduced grip and potentially safety hazards due to the tape coming undone. Secondly, most handle wrapping tapes on the market are connected to the handle or grip with glue or double-sided tape. Therefore, the fixation effect of existing tapes is significantly reduced when facing harsh environments such as high temperatures, rain, and sweat, leading to frequent loosening and detachment of the wrapping structure, failing to meet users' demands for reliability and stability. Furthermore, traditional handle wrapping tapes also have limitations in terms of ease of installation and material durability, making them unsuitable for diverse usage scenarios and user needs. There is an urgent need to develop a new type of handle wrapping tape to effectively solve these technical challenges. Utility Model Content
[0004] The purpose of this utility model is to provide a handle wrapping tape that, through innovative structural design and material selection, breaks through the dependence of traditional handle wrapping tape on the wrapping force. It is reusable, easy to install and remove, and achieves efficient and stable fixation of the handle wrapping tape at the gripping part. It effectively wraps tightly to the gripping part while improving the product's durability and environmental adaptability.
[0005] A handle wrapping tape includes a wrapping tape that is a spiral elastic body. The wrapping tape is wrapped around a handle, and the handle is fitted with an inner elastic retaining ring. The wrapping tape covers the inner elastic retaining ring, and the inner elastic retaining ring and the wrapping tape are fixed together by Velcro.
[0006] Both ends of the wrapping tape have built-in internal elastic retaining rings.
[0007] Both ends of the wrapping tape are provided with outer elastic retaining rings. The outer elastic retaining rings include a first inner ring and a second inner ring that are connected. The inner diameter of the first inner ring is smaller than the inner diameter of the second inner ring. The first inner ring is sleeved on the end of the handle. The inner end face of the first inner ring is axially limited to the inner elastic retaining ring. A part of the second inner ring is sleeved on the outer surface of the wrapping tape, and the other part of the second inner ring is sleeved on the Velcro.
[0008] The inner diameter of the inner elastic retaining ring is smaller than the outer diameter of the grip.
[0009] The inner diameter of the inner elastic retaining ring and the inner diameter of the first inner ring are both smaller than the outer diameter of the handle, and the inner diameter of the second inner ring of the outer elastic retaining ring is smaller than the outer diameter of the wrapping tape and the outer diameter of the inner elastic retaining ring.
[0010] The outer surface of the wrapping tape is provided with a plurality of bumps and recesses arranged in a rectangular array.
[0011] Each bump has a height of 0.3 to 3 mm and a width of 3 to 25 mm, and the distance between two adjacent bumps is 3 to 15 mm.
[0012] The wrapping tape is injection molded from thermoplastic polyurethane elastomer.
[0013] The pitch of the winding tape is 10–45 mm, and the helix angle is 25°–75°.
[0014] The Velcro is welded to the inner elastic retaining ring and wrapping tape by ultrasonic waves or adhesive.
[0015] The beneficial effects of this utility model are as follows: The inner elastic retaining ring is fitted onto the handle at both ends of the wrapping tape to position it. Velcro is used to secure the inner elastic retaining ring to the wrapping tape, simplifying installation. Then, the outer elastic retaining ring is pressed onto the wrapping tape, inner elastic retaining ring, and handle for fixation, thus providing double reinforcement to the wrapping structure. The wrapping tape is made of thermoplastic polyurethane elastomer in a spiral shape. Based on the mutual reinforcement of material properties and the spiral wrapping method, the wrapping tape adheres tightly to the handle without precise control of the wrapping force, effectively preventing it from loosening or falling off in harsh environments such as high temperature, rain, and sweat, thus enhancing the durability of the wrapping tape. The wrapping tape's installability and detachability, along with the high elasticity, high and low temperature resistance, hydrolysis resistance, and anti-aging properties of the wrapping material, significantly extend product life. Its surface array of concave and convex features provides excellent anti-slip properties and a comfortable grip. Even in high-temperature environments, the material maintains good elasticity, preventing tape displacement due to softening. This wrapping tape represents an updated and improved product.

[0018] Figure 3 This is an assembly diagram of the winding structure at both ends of the tape (with the outer elastic retaining ring cut in half). Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] The handle wrapping strap of this invention can be applied to the handles or grips of fishing rods, badminton rackets, table tennis rackets, tennis rackets, golf clubs, bicycles, motorcycles, etc. Figure 1 , 2 Figure 3 shows an example of its application to a fishing rod.
[0021] The wrapping tape includes a wrapping tape 1, an inner elastic retaining ring 2, and an outer elastic retaining ring 3. One inner elastic retaining ring 2 and one outer elastic retaining ring 3 are respectively provided at both ends of the wrapping tape 1. The structures of the two ends of the wrapping tape 1 and the inner elastic retaining ring 2 and outer elastic retaining ring 3 are completely identical, achieving a double reinforcement effect of the inner elastic retaining ring 2 and outer elastic retaining ring 3 on the wrapping tape 1's winding structure. The wrapping tape 1 is injection molded from thermoplastic polyurethane elastomer. The wrapping tape 1 is spirally shaped, with a pitch of 10–45 mm, preferably 15 mm, and a spiral angle of 25°–75°, preferably 30°.
[0022] The outer surface of the wrapping tape 1 is provided with a plurality of bumps 6 arranged in a rectangular array. The height of each bump is 0.3 to 3 mm, preferably 2 mm, and the width is 3 to 25 mm, preferably 10 mm. The distance between two adjacent bumps is 3 to 15 mm, preferably 5 mm. The bumps 6 provide a comfortable grip and play a role in anti-slip protection.
[0023] The disadvantages of existing wrapping tape are as follows:
[0024] (1) The wrapping tape made of composite PU, EVA foam, cotton cloth and other materials has weak UV resistance during outdoor sports. It is prone to yellowing, peeling and cracking when exposed to sunlight and temperature and humidity changes for a long time.
[0025] (2) The tape is prone to softening and deformation under high temperature conditions and hardening under low temperature conditions. In extreme environments, its temperature resistance is insufficient, which causes its performance to drop sharply.
[0026] (3) Some of the materials used in the wrapping tape contain plasticizers (such as phthalates), which release toxic substances such as dioxins when burned and are non-degradable, posing environmental hazards;
[0027] (4) The composite PU material used for wrapping has strong water absorption. It is not easy to dry after absorbing water, resulting in a slippery grip, increased weight of the rod, and the residual moisture accelerates internal gelation and corrodes the paint on the rod wall.
[0028] (5) The surface of the wrapping tape easily absorbs bait and sweat stains, resulting in stain residue. After cleaning, the stain penetration rate is high, and after long-term use, it will become moldy, discolored, and produce an odor.
[0029] This utility model's handle wrapping tape uses thermoplastic polyurethane elastomer, whose material properties include tear resistance, elasticity, and skin-friendliness, effectively overcoming the aforementioned shortcomings, preventing aging, improving durability, and allowing for multiple disassembly and reuse, thus reducing maintenance costs. Based on the combined properties of thermoplastic polyurethane elastomer and the spiral winding method, the tape adheres tightly to the handle without needing to consider the winding force when wrapping it, effectively preventing the tape from loosening or falling off in harsh environments such as high temperature, low temperature, rain, and sweat, enhancing the durability of the handle wrapping tape and overcoming the shortcomings of existing handle wrapping tapes, such as easy loosening, dirt accumulation at the seams, and surface pores that make it difficult to thoroughly clean.
[0030] When installing the aforementioned handle wrapping tape onto a fishing rod, the assembly process is as follows:
[0031] (1) According to the length of the wrapping tape 1 required for the handle 4 of the fishing rod, put the two inner elastic fixing rings 2 into the corresponding positions of the handle 4. Since the inner diameter of the inner elastic fixing ring 2 is smaller than the outer diameter of the handle 4, the inner elastic fixing ring 2 firmly hugs the outer surface of the handle 4. In addition, the inner elastic fixing ring 2 is made of rubber with added tackifier. The radial clamping force generated by the elastic deformation of the inner elastic fixing ring 2 material, combined with the frictional resistance formed by the tackifier, plays a role in preventing rotation and slippage.
[0032] (2) The wrapping tape 1 is slipped onto the handle 4. The inner surface of one end of the wrapping tape 1 is fixed to the hook and loop fastener 5a on the outer surface of an inner elastic retaining ring 2 via the hook and loop round surface 5b. The hook and loop round surface 5b is smaller than the hook and loop fastener 5a, so that a portion of the hook and loop fastener 5a protrudes from the hook and loop round surface 5b. Under the positioning effect of one end of the wrapping tape 1, the wrapping tape 1 is then wrapped around the handle 4. When it is wrapped to another inner elastic retaining ring 2, the inner surface of the other end of the wrapping tape 1 is fixed to the hook and loop fastener 5a on the outer surface of an inner elastic retaining ring 2 via the hook and loop round surface 5b. The hook and loop round surface 5b and the hook and loop fastener 5a are welded to the wrapping tape 1 and the inner elastic retaining ring 2 respectively by ultrasonic or glue (preferably ultrasonic). The use of the hook and loop fastener 5 facilitates the disassembly and cleaning of the wrapping tape 1.
[0033] (3) An outer elastic retaining ring 3 is fitted onto each end of the wrapping tape 1. The outer elastic retaining ring 3 is formed by connecting a first inner ring 3a and a second inner ring 3b. The first inner ring 3a and the second inner ring 3b are interconnected. The inner diameter of the first inner ring 3a is smaller than the inner diameter of the second inner ring 3b, thus forming a step A at the connection between the first inner ring 3a and the second inner ring 3b. The first inner ring 3a is fitted onto the end 4a of the handle 4, and the outer end face 3c of the first inner ring 3a is flush with the end face 4b of the handle 4, so that the inner end face 3d of the first inner ring 3a is axially limited to the inner elastic retaining ring 2, thereby achieving the axial positioning of the outer elastic retaining ring 3. Since the inner diameter of the first inner ring 3a is smaller than the outer diameter of the handle 4, the first inner ring 3a firmly hugs the outer surface of the handle 4. A portion 3e of the second inner ring is fitted onto the outer surface of the wrapping tape 1, and another portion 3f of the second inner ring is fitted onto the exposed portion 5c of the hook and loop fastener 5a from the rounded surface 5b of the hook and loop fastener. This allows the outer elastic retaining ring 3 to grip the two different materials, resulting in a more secure grip. Furthermore, the inner diameter of the second inner ring 3b is smaller than the outer diameter of the wrapping tape 1 and the outer diameter of the inner elastic retaining ring 2, further enhancing the gripping force between the second inner ring 3b and the outer surface of the wrapping tape 1 and the exposed portion 5c of the hook and loop fastener 5a. In addition, the outer elastic retaining ring 3 is made of rubber with added tackifier, utilizing the adhesive and gripping force of the outer elastic retaining ring 3 to prevent rotational slippage.
