Description

Technical Field

[0001] The present invention relates to a handlebar tape that is wound around a grip portion such as a handlebar of a two-wheeled vehicle and used.

Background Art

[0002] As a tape wound around a grip portion of a handlebar of a bicycle or the like, a handlebar tape (also referred to as a "cover tape", etc.) is widely used. Among the handlebar tapes for bicycles, those attached to so-called drop handlebars generally have a length of 1800 mm, a width of 30 mm, and a thickness of about 2.5 mm. As the material of the tape, thermoplastic polyurethane (TPU), ethylene-vinyl acetate copolymer resin (EVA), microfiber (nylon or polyester), etc. are used. In recent years, silicone foam or the like may also be used. In order to provide anti-slip performance or improve the grip feeling, the handlebar tape may have a concavo-convex shape provided on the tape surface.

[0003] As a technique for providing convex portions on the surface of a handlebar tape, a bicycle bar tape in which a thin rubber layer is integrally provided on the back surface of a cotton tape is known (see Patent Document 1). This is a handlebar tape in which a thin rubber layer is integrally provided on the back surface of the handlebar tape in order to make the winding of the handlebar tape around the handlebar of the bicycle easy and firm. However, the bicycle bar tape of Patent Document 1 is produced by applying an unvulcanized rubber solution to one side of a cotton tape and passing it through a vulcanization chamber for vulcanization, and since it does not use a tape of a resin material, there is a problem that the degree of freedom in processing is low and it is difficult to produce a tape with a complex concavo-convex shape.

[0004] Typical handlebar tape made from resin is produced by a process called calendering, where the resin is melted and kneaded between heated rolls, then stretched to a desired thickness by passing it through multiple rolls. Calendering is often used to produce wide, flat products such as films and sheets, and it is also possible to create patterned products by using roll-shaped molds engraved with patterns. However, when handlebar tape is manufactured using calendering, even if a textured surface is created on the tape, the height of the protrusions is often less than 0.3 mm due to limitations of the manufacturing process.

[0005] Furthermore, the length of handlebar tape typically used on drop handlebars is often around 1800mm or more, and it was generally recognized that production by injection molding or compression molding was not practical. Furthermore, extrusion molding, a widely known method for producing long molded products, can only produce products with the same cross-sectional shape along the longitudinal direction, which has been a limitation on design patterns. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Publication No. 61-132184 [Overview of the project] [Problems that the invention aims to solve]

[0007] As mentioned above, conventionally, handlebar tape was mainly manufactured by calendering, so even if a textured surface was created, the height of the protrusions remained below 0.3 mm. Since such tapes were common, it was difficult to create higher, more three-dimensional protrusions in order to further improve grip and shock absorption.

[0008] If handlebar tape could be produced by injection molding or direct compression molding, the range of applicable design patterns and material options would expand dramatically, offering significant benefits to both producers and consumers. However, since handlebar tape is typically 1800mm or longer, it was not practical to produce it using molds of a size that could be used with conventional injection molding or direct compression molding machines.

[0009] In view of these circumstances, the present invention aims to provide motorcycle handlebar tape that can further improve grip, shock absorption, grip comfort, and durability. [Means for solving the problem]

[0010] Attempting to produce handlebar tape in a flat state using injection molding or direct pressure molding would require large molding machines that are not typically found in manufacturing plants producing general resin molded products, making it impractical. Therefore, the inventors focused on the fact that the finished product is flexible and easily deformable, and that molding it into a shape other than a long, flat strip does not pose any problems in terms of use. They discovered that by shaping the finished product into a spiral, the maximum side length of the mold can be made more compact.

[0011] In other words, in order to solve the above problems, the motorcycle handlebar tape of the present invention is a tape that is wrapped around a motorcycle handlebar, and is characterized in that the tape shape is formed in a spiral shape. By forming the tape in a spiral shape rather than a long strip, motorcycle handlebar tape approximately 1800mm in length can be easily manufactured using injection molding or direct compression molding. This makes it possible to provide products with three-dimensional designs that have sufficient recess depth (or convex height) that could not be produced with calendering. Furthermore, since the handlebar tape can be manufactured by injection molding or direct compression molding instead of extrusion molding, it is possible to produce products with a wide variety of design patterns other than those with the same cross-sectional shape in the longitudinal direction that can be produced with extrusion molding. A spiral shape refers to a shape that is wrapped diagonally around a roughly cylindrical or cylindrical body. The direction of the spiral can be either right-handed or left-handed. When wrapping flat handlebar tape around a handlebar, the outer surface (front) of the tape is pulled more than the inner surface (back), making it more prone to scratches, tearing, and ripping. However, forming the tape in a spiral shape improves these conditions and extends the product's lifespan.

[0012] In the motorcycle handlebar tape of the present invention, the spiral tape may have spiral grooves between adjacent tapes and may be cylindrical in shape. By providing spiral grooves between adjacent tapes, the adjacent tapes remain connected, allowing the user to easily cut and wrap them when in use.

[0013] In the motorcycle handlebar tape of the present invention, the spiral tape may have a thinner thickness at both ends in the width direction compared to the center. This allows the tape to be wrapped around the object without any gaps.

[0014] Specifically, for spiral-shaped tape, it is desirable that one end on the surface side and the other end on the back side have less thickness than the center. This improves the grip when wrapping the tape and allows the tape to be wrapped around the object without any gaps.

[0015] In the motorcycle handlebar tape of the present invention, the spiral tape may have protruding or linear uneven shapes on the back side of the tape. Providing protruding or linear uneven shapes improves grip or shock absorption. In addition, providing protruding or linear uneven shapes on the back side of the tape improves the feel of the grip. Here, an uneven shape means a recessed part, a raised part, or an uneven shape formed thereon. Examples of protruding parts include cylindrical protrusions, cylindrical protrusions, double hexagonal lattice-shaped protrusions, diamond-shaped protrusions, or cedar-shaped protrusions.

[0016] In the motorcycle handlebar tape of the present invention, the spiral tape may have protruding or linear uneven shapes on the surface side of the tape. By providing protruding or linear uneven shapes on the surface side of the tape, grip or shock absorption can be improved. Furthermore, the protruding or linear uneven shapes may be provided on both the surface and back side of the tape to further improve grip, shock absorption, or grip comfort.

[0017] In the motorcycle handlebar tape of the present invention, the spiral shape of the tape is preferably a spiral wound around a roughly cylindrical shape. By having a spiral wound shape, it can be wrapped smoothly along the shape of the handlebar, and durability is improved.

[0018] In the motorcycle handlebar tape of the present invention, the spiral shape of the tape may be a spiral wrapped around a substantially polygonal prism or an elliptical prism. Since the cross-sectional shape of a motorcycle handlebar is not limited to a substantially circular shape, by making the spiral shape of the tape a spiral wrapped around a substantially polygonal prism or an elliptical prism, it is possible to make the specifications suitable for the shape of the target handlebar, resulting in a handlebar tape that is efficient to wrap and has excellent durability.

[0019] In the handlebar tape for a two-wheeled vehicle of the present invention, it is preferable that the diameter of the helix is set larger than the outer diameter of the handlebar for a two-wheeled vehicle to be wound. Due to the relative relationship between the diameter and pitch of the helix of the tape, when the tape is deformed to a diameter smaller than the diameter of the helix of the tape, the end portions in the width direction of the tape will automatically overlap. Therefore, when the diameter of the helix of the tape formed in a spiral shape is formed larger than the diameter during actual use, that is, the outer diameter of the handlebar for a two-wheeled vehicle to be wound, when the tape is wound around the handlebar, the ends in the width direction of the tape will naturally overlap, and it becomes easy to wind the tape formed in a spiral shape around the object without any gaps.

[0020] Specifically, it is preferable that the diameter of the substantially cylindrical cavity formed by being formed in a spiral shape is 30 to 70 mm. Since the outer diameter of the cylindrical portion of a general drop handlebar is about 23.8 mm, by setting the diameter of the cavity to 30 to 70 mm, the shape is closer to the mounting form than the bar tape formed in a flat shape, so the winding operation becomes easy and the maintenance burden is reduced. Also, it can have a diameter close to the diameter of the handlebar to be actually wound, and it can be made into a structure with less load when wound and less likely to deteriorate. Also, the diameter of the substantially cylindrical cavity formed by being formed in a spiral shape may be 200 to 300 mm. By setting the diameter of the cavity to 200 to 300 mm, it can be manufactured with a wide forming machine.

Effects of the Invention

[0021] According to the handlebar tape for a two-wheeled vehicle of the present invention, there is an effect that grip performance, shock absorption performance, comfortable grip feeling, and durability can be further improved.

Mode for Carrying Out the Invention

[0023] Hereinafter, an example of an embodiment of the present invention will be described in detail while referring to the drawings. Note that the scope of the present invention is not limited to the following examples and illustrated examples, and numerous changes and modifications are possible.

Example

[0024] Figure 1 shows an external perspective view of the motorcycle handlebar tape of Example 1. As shown in Figure 1, the motorcycle handlebar tape 1 is used by attaching it to a drop handlebar (not shown), and consists of a base portion 2 and an overlapping portion 3. The overlapping portion 3 is thinner than the base portion 2, and overlapping portions 31 and 32 are formed at each end of the base portion 2. The material of the base portion 2 and the overlapping portion 3 is silicone rubber and is integrally molded. The material of the motorcycle handlebar tape 1 is not limited to silicone rubber, and thermoplastic polyurethane (TPU), ethylene-vinyl acetate copolymer resin (EVA), microfiber (nylon or polyester), etc. may also be used. Generally, to ensure that the tape can be wrapped around objects that do not have a straight shape without leaving any gaps, it is often recommended to overlap the tape by about 1 / 4 to 1 / 3 of its width. Therefore, the tape is shaped to be thinner at both ends in the width direction. The motorcycle handlebar tape 1 has a spiral shape with the surface 4 facing outwards and the back surface 5 facing inwards. The diameter φ1 of the gap 6 formed by the spiral shape of the motorcycle handlebar tape 1 is 50 mm.

[0025] Figure 2 shows the motorcycle handlebar tape of Example 1 stretched into a flat sheet, with (1) being an overall view and (2) being a magnified view of the dashed line area. As shown in Figure 2(1), in its unfolded state, the motorcycle handlebar tape 1 is in the shape of a strip, similar to a general handlebar tape. The tape length L of the motorcycle handlebar tape 1 shown in Figure 2(1) is approximately 500 mm, but it is possible to manufacture a motorcycle handlebar tape 1 with a length of approximately 1800 mm using a known direct pressure molding machine or injection molding machine. The tape width W of the motorcycle handlebar tape 1 is 28 mm. As shown in Figure 2(2), a base portion 2 is provided in the center of the motorcycle handlebar tape 1, and overlapping winding portions 31 and 32 are formed at both ends of the base portion 2, respectively.

[0026] Figure 3 shows an image of the wrapping of the motorcycle handlebar tape according to Example 1. Since the overlapping sections (31, 32) are made thinner than the base section 2, as shown in Figure 3, when the motorcycle handlebar tape 1 is wrapped around the handlebar 12, the thickness at the point where the overlapping sections 31 and 32 overlap does not become excessively large.

[0027] Figure 4 shows an explanatory diagram of the mold used in direct compression molding. Figure 5 also shows an explanatory diagram of direct compression molding. As shown in Figure 4, the mold 7 consists of cavities (7a, 7b) and a core 7c, with a molding section 70a in cavity 7a and a molding section 70b in cavity 7b. For illustrative purposes, the shape of the mold 7 in Figure 4 is a simplified representation. When manufacturing motorcycle handlebar tape 1 by direct pressure molding, the material 11 (see Figure 5) and core 7c of the motorcycle handlebar tape 1 are placed on the cavity 7b. As shown in Figure 5, the material 11, softened by the heat of a mold 7 heated in a direct pressure molding machine (not shown), is sandwiched between the mold 7, and pressure is applied by the direct pressure molding machine to crush it, thereby molding the material 11 into the mold 7.

[0028] Figure 6 is an illustrative diagram of the product after direct pressure molding, where (1) shows an example of molding in a spiral-shaped section. The pitch P1 of the handlebar tape 1 for motorcycles shown in Figure 6(1) is 30 mm. As mentioned above, the tape width W is 28 mm. If the tape width W of the handlebar tape 1 for motorcycles to be molded is 28 mm and the spiral pitch P1 when placed in the mold 7 is 30 mm, there is a 2 mm wide gap separating the member from the part one pitch away. This clamps the cavity (7a, 7b) of the mold 7 and the core 7c, enabling molding by direct pressure molding or injection molding. As shown in Figure 2, if the dimensions of the motorcycle handlebar tape 1 in its unfolded state are a tape width W of 28 mm and a tape length L of 1800 mm, and if it is arranged in a spiral shape with an inner diameter φ1 of 50 mm and a pitch P1 of 30 mm, then it will be approximately 11.5 pitches and 1800 mm in length. Therefore, it can be manufactured using a molding machine that can form it with a mold 7 that can contain a space of approximately 50 mm in diameter and 350 mm in size.

[0029] Figure 6(2) shows an example in which a spiral groove 13 is formed to facilitate cutting during post-processing. The groove 13 is thinner than the overlapping sections (31, 32) and is designed to be easily separated by hand. Depending on the shape of the cavity (7a, 7b) and core 7c, as shown in Figure 6(1), the tape can be cut into strips during the molding stage using a direct pressure molding machine, or, as in the motorcycle handlebar tape 100 shown in Figure 6(2), the overlapping sections 31 and 32 can be connected in a roughly cylindrical shape during the molding stage using a direct pressure molding machine, and then cut during post-processing. Alternatively, the tape can be sold in a roughly cylindrical shape with the overlapping sections 31 and 32 connected, and the user can separate them and wrap them around the object for use. Selling the tape in a connected roughly cylindrical shape makes it less prone to deformation and easier to handle. [Examples]

[0030] In the motorcycle handlebar tape 1 of Example 1, the diameter φ1 of the gap 6 formed by the spiral shape was 50 mm, but the diameter of the gap may be larger or smaller. Figure 7 shows the external view of the motorcycle handlebar tape of Example 2, where (1) is an external plan view and (2) is an external perspective view. The dimensions of the motorcycle handlebar tape 1a shown in Figure 7(1) or (2) are, when stretched into a flat strip, a tape width of 28 mm and a tape length of 1800 mm. In Figures 7(1) and (2), the gaps 6a are arranged in a spiral shape with a diameter φ2 of 250 mm and a pitch P2 of 30 mm. Therefore, as shown in Figure 7(2), a pitch of approximately 2.5 corresponds to a length of 1800 mm, and it can be manufactured using an injection molding machine or direct pressure molding machine that can mold with a mold 7 that can contain a space of approximately 250 mm in diameter and 75 mm in size. Thus, by shaping the diameter φ2 of the gap 6a between the motorcycle handlebar tape 1a to be larger, due to the relative relationship between the diameter and pitch of the spiral, when wrapped around the handlebar 12, the ends of the motorcycle handlebar tape 1a in the width direction naturally overlap, making it easy to wrap the motorcycle handlebar tape 1a around the handlebar 12 without any gaps. [Examples]

[0031] The handlebar tape for motorcycles of the present invention is flexible and has sufficient elasticity even if there is a step on the back side, that is, the side that contacts the handlebar 12, in other words, on the core 7c side of the mold 7. Therefore, even if the core 7c of the mold 7 has a shape such as grooves or protrusions, it can be expanded and pulled out of the mold, so a structure that creates a difference in thickness may be provided on the back side. Figure 8 shows the external view of the motorcycle handlebar tape of Embodiment 3, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 8(1) or (2), on the surface 4 side of the motorcycle handlebar tape 1b, there is no step between the base 2b and the overlapping wrap portion 31b, but there is a step between the base 2b and the overlapping wrap portion 32b. Conversely, on the back side 5, there is no step between the base 2b and the overlapping wrap portion 32b, but there is a step between the base 2b and the overlapping wrap portion 31b. This shape allows the tape to be wrapped around objects that do not have a straight shape without any gaps. [Examples]

[0032] Figure 9 shows an external view of the motorcycle handlebar tape of Example 4. As shown in Figure 9, unlike the motorcycle handlebar tape 1b of Example 3, the overlapping sections (31c, 32c) of the motorcycle handlebar tape 1c of Example 4 have a slope rather than a step, and the overall cross-sectional shape in the width direction is approximately parallelogram-shaped. This allows it to be wrapped without gaps even around objects that do not have a linear shape. [Examples]

[0033] Figure 10 shows the external view of the motorcycle handlebar tape of Example 5, where (1) shows an elliptical cross-section and (2) shows a roughly rectangular cross-section. As shown in Figure 10(1), the motorcycle handlebar tape 1d, consisting of a base portion 2d and overlapping winding portions (31d, 32d), may be molded to have an elliptical cross-section. Also, as shown in Figure 10(2), the motorcycle handlebar tape 1e, consisting of a base portion 2e and overlapping winding portions (31e, 32e), may be molded to have a roughly rectangular cross-section. By molding it to be elliptical or roughly rectangular, rather than being limited to a spiral shape, it is possible to create a specification that matches the shape of the target handlebar 12, resulting in a handlebar tape with excellent efficiency in wrapping work and durability. In addition, it can be easily boxed into cases suitable for transportation and sales. [Examples]

[0034] Figure 11 shows the external view of the motorcycle handlebar tape of Example 6, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 11(1), in the motorcycle handlebar tape 1f, the surface 4 side of the base 2f and overlapping winding parts (31f, 32f) has the same shape as the motorcycle handlebar tape 1. In contrast, on the back side 5, as shown in Figure 11(2), a linear protrusion 8f and a linear recess 9f are formed at the base 2f. By providing such protrusions and recesses, shock absorption and shape conformability are improved. Because the molding material used is flexible and has sufficient elasticity, even if the core 7c of the mold 7 has grooves or protrusions, it can be inflated and pulled out of the mold 7. [Examples]

[0035] Figure 12 shows the external view of the motorcycle handlebar tape of Example 7, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 12, in the motorcycle handlebar tape 1g, the surface 4 side of the base 2g and the overlapping winding parts (31g, 32g) has the same shape as the motorcycle handlebar tape 1. In contrast, on the back surface 5 side, as shown in Figure 12(2), multiple cylindrical protrusions 8g and recesses 9g are formed at the base 2g. By providing such protrusions and recesses, shock absorption and shape conformability are improved. Because the molding material used is flexible and has sufficient elasticity, even if the core 7c of the mold 7 has grooves or protrusions, it can be inflated and pulled out of the mold 7. Thus, since the motorcycle handlebar tape of the present invention can be manufactured by injection molding or direct compression molding instead of calendering, it is possible to provide a product with a three-dimensional design that has sufficient recess depth (or convex height) that could not be produced by calendering. [Examples]

[0036] Figure 13 shows the external view of the motorcycle handlebar tape of Example 8, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 13(1), multiple cylindrical protrusions 8h are formed on the surface 4 side of the motorcycle handlebar tape 1h. As shown in Figure 13(2), the protrusions 8h are formed not only on the base 2h but also on parts of the overlapping winding sections (31h, 32h). This allows the protrusions 8h to be evenly distributed when the cable is wrapped around the handlebar 12. [Examples]

[0037] Figure 14 shows the external view of the motorcycle handlebar tape of Example 9, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 14(1), multiple cylindrical protrusions 8i are formed on the surface 4 side of the motorcycle handlebar tape 1i. As shown in Figure 14(2), the protrusions 8i are formed not only on the base 2i but also on a part of the overlapping winding sections (31i, 32i). Furthermore, the protrusions 8i on the overlapping winding sections (31i, 32i) are taller than those on the base 2i. This is to balance the thickness of the base 2i, which is thicker than the overlapping winding sections (31i, 32i). Alternatively, the height of the protrusions 8i could be uniform. [Examples]

[0038] Figure 15 shows the external view of the motorcycle handlebar tape of Example 10, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 15(1), a convex portion 8j, which is a double hexagonal grid-like projection, is formed on the surface 4 side of the motorcycle handlebar tape 1j. As shown in Figure 15(2), the protrusion 8j is formed not only on the base 2j but also on a part of the overlapping winding section (31j, 32j). Furthermore, the protrusion 8j is taller in the area corresponding to the base 2j than in the area corresponding to the overlapping winding section (31j, 32j). This is because the base 2j and the overlapping winding section (31j, 32j) have approximately the same thickness, so the shape of the protrusion 8j is used to create a difference in thickness between the base 2j and the overlapping winding section (31j, 32j). Alternatively, the thickness of the base 2j and the overlapping winding section (31j, 32j) could be different, and the height of the protrusion 8j could be made uniform. [Examples]

[0039] Figure 16 shows the external view of the motorcycle handlebar tape of Example 11, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 16(1), diamond-shaped protrusions, called convex portions 8k, are formed on the surface 4 side of the motorcycle handlebar tape 1k. As shown in Figure 16(2), the protrusion 8k is formed not only on the base 2k but also on a part of the overlapping winding section (31k, 32k). Furthermore, the protrusion 8k is taller in the area corresponding to the base 2k than in the area corresponding to the overlapping winding section (31k, 32k). This is because the base 2k and the overlapping winding section (31k, 32k) have approximately the same thickness, so the shape of the protrusion 8k is used to create a difference in thickness between the base 2k and the overlapping winding section (31k, 32k). Alternatively, the thickness of the base 2k and the overlapping winding section (31k, 32k) may be different, and the height of the protrusion 8k may be uniform. [Examples]

[0040] Figure 17 shows the external view of the motorcycle handlebar tape of Example 12, where (1) is an external perspective view and (2) is an enlarged image of the dashed line area. As shown in Figure 17(1), the surface 4 side of the motorcycle handlebar tape 1l has protrusions 8l which are cedar-grain-like projections. As shown in Figure 17(2), the protrusion 8l is formed not only on the base 2l but also on the entire surface 4, including the overlapping winding sections (31l, 32l). Furthermore, the protrusion 8l is slightly taller in the area corresponding to the base 2l than in the area corresponding to the overlapping winding sections (31l, 32l). This is because the base 2l and the overlapping winding sections (31l, 32l) have approximately the same thickness, so the shape of the protrusion 8l is used to create a difference in thickness between the base 2l and the overlapping winding sections (31l, 32l). Alternatively, the thickness of the base 2l and the overlapping winding sections (31l, 32l) may be different, and the height of the protrusion 8l may be uniform. [Industrial applicability]
