Description

Technical Field

[0001] This utility model relates to the field of grips, and in particular to a composite double-layer grip for fishing rods. Background Technology

[0002] The fishing rod grip is a crucial component connecting the angler and the rod, directly impacting handling, comfort, and fishing efficiency. Traditional fishing rod grips are mostly made of natural materials (such as bamboo, cork) or simply wrapped in rubber, resulting in problems such as heavy weight, easy aging, and poor feel. With the professionalization of fishing and advancements in materials science, modern grip technology is gradually evolving towards lightweighting, functionality, and ergonomics, with core goals including:

[0003] Weight reduction and balance: Reduce overall weight through material optimization and improve the center of gravity distribution of the fishing rod.

[0004] Anti-slip and shock absorption: Reduces hand fatigue and improves the ability to buffer high-frequency vibrations (such as the struggle of a large fish).

[0005] Environmental adaptability: Durability requirements to cope with complex environments such as seawater, sweat, and ultraviolet radiation.

[0006] Therefore, EVA (ethylene-vinyl acetate copolymer) grips have emerged. EVA, the core material of EVA grips, is a polymer material with certain elasticity, cushioning and weather resistance. Through foaming process, it can be made into a lightweight, non-slip and shock-absorbing grip structure.

[0007] However, EVA grips have poor wear resistance and are prone to aging and hardening over time, resulting in a poor feel, short lifespan, and weak impact resistance. While EVA grips do have resilience, their rebound period is long, and they easily lose their elasticity under significant pressure. Furthermore, EVA's high water absorption makes it prone to absorbing water when fishing near water, causing slippage. Utility Model Content

[0008] The purpose of this invention is to solve one of the above-mentioned defects of EVA grips and to provide a composite double-layer grip for fishing rods.

[0009] The objective of this utility model is achieved through the following means:

[0010] A composite double-layer grip for fishing rods includes an inner core with an axially penetrating shaft hole for fitting snugly onto the rod handle. The inner core is characterized by being made of highly elastic cylindrical EVA foam material, with a layer of sheet-like POE foam material covering its outer surface to improve the grip's surface abrasion resistance and resilience. The inner core and the sheet-like POE foam material are bonded together by an adhesive layer, which accelerates the rebound of the inner core under the pulling action of the sheet-like POE foam material and the adhesive layer.

[0011] As a preferred embodiment, the sheet-like POE foam material has a rectangular sheet structure, which, when rolled up, completely covers the inner core.

[0012] As a preferred embodiment, the sheet-like POE foam material has a strip-shaped sheet structure, which completely covers the inner core by winding.

[0013] As a preferred embodiment, the thickness of the sheet-like POE foam material is 1.3 to 2.5 mm.

[0014] As a preferred embodiment, the outer surface of the sheet-like POE foam material is provided with an embossed structure for anti-slip purposes.

[0015] As a preferred embodiment, the adhesive layer is a resin adhesive.

[0016] As a preferred embodiment, the adhesive layer is a polyurethane adhesive or a PUR hot melt adhesive.

[0017] As a preferred embodiment, the sheet-like POE foam material has a single-layer monochromatic structure or a double-layer heterochromatic structure.

[0018] The beneficial effects of this invention are as follows: 1. By coating the outer surface of the EVA inner core with sheet-like POE foam material, the wear resistance, anti-slip properties, and weather resistance of the grip are increased, while also resisting ultraviolet radiation and ozone aging; 2. The EVA inner core and the sheet-like POE foam material are bonded together with an adhesive layer, utilizing the high-speed resilience of POE to drive the EVA inner core to rebound quickly; 3. It can reduce the contact between the EVA inner core and the outside world, slow down the aging of the EVA inner core, and improve the service life of the grip; 4. Utilizing the characteristic that POE has a lower water absorption rate than EVA, the grip's anti-slip properties in humid and excessively wet environments are improved. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0030] Example 1, as Figure 1-3 As shown, this utility model discloses a composite double-layer grip for fishing rods, including an inner core 10. The inner core 10 has an axial through hole 11 for fitting onto the handle of the fishing rod to form a tight fit. The inner core 10 is made of a highly elastic cylindrical EVA foam material. In this embodiment, an EVA foam material with a hardness of 65-75 degrees is used.

[0031] Based on long-term user feedback and actual product testing conducted by the applicant, EVA foam material exhibits poor wear resistance and resilience. For example, when fishing from a boat, the handle is subjected to prolonged pressure and friction from the boat's hull edge, leading to rapid deformation and aging. Additionally, if a large amount of water comes into contact with the EVA handle, the friction between the handle and the palm can be significantly reduced, resulting in slippage or the rod falling off.

[0032] POE foam material boasts strong weather resistance, resisting UV rays and ozone aging, making it suitable for long-term outdoor use. POE foam material also exhibits good temperature resistance, with a wide operating temperature range (-50℃~120℃), maintaining its elasticity even at high temperatures. Furthermore, POE foam material possesses excellent mechanical properties, exhibiting high wear resistance and impact resistance, making it suitable for dynamic load scenarios such as fishing, golf, and tennis.

[0033] By coating the outer surface of the EVA inner core 10 with a layer of sheet POE foam material 20, the grip's wear resistance, anti-slip properties, and weather resistance are increased. At the same time, it is resistant to ultraviolet rays and ozone aging.

[0034] Therefore, a layer of sheet-like POE foam material 20 is provided on its outer surface. POE foam 20 itself has strong wear resistance and fast rebound speed, thus solving the defects of EVA material.

[0035] In order to fully bond the inner core 10 with the sheet POE foam material 20, the adhesive layer 30 is a resin adhesive. Resin adhesive has strong bonding adaptability, is environmentally friendly, has strong gap filling ability, and has a wide temperature resistance range.

[0036] Both EVA and POE have good adhesion properties. An adhesive layer 30 is provided between the inner core 10 and the sheet POE foam material 20. The inner core 10 is bonded to the sheet POE foam material 20 through the adhesive layer 30, which can reduce the contact between the EVA inner core 10 and the outside world, thereby slowing down the aging of the EVA inner core 10 and improving the service life of the grip. In addition, the sheet POE foam material 20 pulls the inner core 10 through the adhesive layer 30, and uses the high-speed rebound characteristics of POE to drive the EVA inner core 10 to rebound quickly.

[0037] In this embodiment, the adhesive layer 30 is a polyurethane adhesive or a PUR hot melt adhesive. In practical applications, the adhesive layer 30 is not limited to polyurethane adhesive or PUR hot melt adhesive, but can also be other highly flexible resin adhesives.

[0038] To save costs and ensure that the sheet-like POE foam material 20 can drive the inner core 10 to rebound more quickly, the thickness of the sheet-like POE foam material 20 is 1.3 to 2.5 mm. In this embodiment, the thickness of the sheet-like POE foam material 20 is 2 mm. In practical applications, the thickness of the sheet-like POE foam material 20 is not limited to 2 mm; it can be 1.3 mm or 2.5 mm.

[0039] To further enhance the grip's anti-slip properties and aesthetics, such as Figure 4 As shown, the grip surface 21 of the sheet-like POE foam material 20 is provided with an embossed structure for anti-slip purposes.

[0040] In this embodiment, the sheet-like POE foam material 20 is a rectangular sheet-like POE foam material.

[0041] Method for making rectangular sheet POE foam material 20: 1. Foam POE into large sheets. 2. Cut into rectangular sheets according to the required size. 3. Bake in an oven at 170 degrees Celsius for 7-9 minutes. 4. After baking, mold to form texture.

[0042] High temperatures can improve the plastic deformation capacity of POE materials, and then the texture can be quickly shaped by molding.

[0043] The grip manufacturing steps in this embodiment one are as follows:

[0044] Step 1: Fabricate the EVA foam material into an inner core of the required shape and length.

[0045] Step 2: Apply a uniform layer of resin adhesive to the inner core 10 and then wrap the rectangular sheet of POE foam material 20 around the inner core 10 to form a grip.

[0046] Step 3: Let the handle dry.

[0047] The comparison test results of abrasion resistance, slip resistance, and compressive strength between POE and EVA are shown in the table below:

[0048]

[0049] The comparative test results of wear resistance, slip resistance and compressive strength of POE and EVA show that POE has stronger wear resistance, slip resistance and compressive strength than EVA.

[0050]

[0051] Materials generally experience a decrease in tensile strength, elasticity, abrasion resistance, weather resistance, stability, and anti-aging properties after absorbing water. Water absorption tests of POE and EVA show that POE has lower water absorption than EVA, indicating that POE is more adaptable to humid environments and less affected by damp or excessively humid conditions. Utilizing POE's low water absorption rate can improve the grip's anti-slip properties.

[0052] This invention is not limited to fishing rod grips, but can also be applied to golf club grips, tennis racket grips, and other grips.

[0053] In this embodiment, the sheet-like POE foam material has a single-layer, monochromatic structure.

[0054] Example 2, as Figure 5 and Figure 6 As shown, the difference between this embodiment and the above embodiment is that the above embodiment uses a rectangular sheet POE foam material 20 to directly cover the outer surface of the inner core 10. The rectangular sheet POE foam material 20 is generally only suitable for covering cylindrical inner cores 10, while this embodiment uses a strip-shaped sheet POE foam material 20 to wrap around the outer surface of the inner core 10. By designing a unique pattern or anti-slip structure through the wrapping, it is not only suitable for wrapping cylindrical inner cores 10, but also suitable for wrapping spindle-shaped inner cores, conical inner cores or irregular inner cores.

[0055] The grip manufacturing steps in this second embodiment are as follows:

[0056] Step 1: Fabricate the EVA foam material into an inner core of the required shape and length.

[0057] Step 2: Apply a uniform layer of resin adhesive to the inner core 10 and then wrap the strip-shaped POE around the inner core 10 to form a grip.

[0058] Step 3: Let the handle dry.

[0059] Example 3, as Figure 7 As shown, the manufacturing process of Example 3 is the same as that of Example 1. To enhance the aesthetics of the grip, two layers of POE foam material in different colors are used, for example, the bottom layer is red and the top layer is black. After cold pressing, an uneven pattern is formed. After cutting the surface, the red bottom layer is exposed, thus achieving a grip with two colors.

[0060] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
