Description
【０００１】[0001]
本考案は、自転車の車輪用リムに係り、特に自転車の摩耗警告手段付き車輪用 リムに関する。 The present invention relates to a rim for a bicycle wheel, and more particularly to a rim for a bicycle wheel with a warning device.
【０００２】[0002]
従来の自転車の車輪用リム１０は、図３に示すように、円環状の周壁１２と、 周壁１２の外周面の両周縁に沿って対立すると共にそれらの間にタイヤを保持す るための空間１０１をなすように周壁１２と一体に形成された一対の円環状の側 壁１１とを有する。一対の側壁１１には、それぞれ空間１０１を背にしている外 側面１１３があり、外側面１１３は、通常、ブレーキ面として使用され、図４に 示すように、ブレーキがかけられるとブレーキゴム１３が当接する摩擦面として 使用される。 As shown in FIG. 3, a conventional bicycle wheel rim 10 has an annular peripheral wall 12 and a space for opposing along both peripheral edges of the outer peripheral surface of the peripheral wall 12 and for holding a tire therebetween. A pair of annular side walls 11 are formed integrally with the peripheral wall 12 so as to form 101. Each of the pair of side walls 11 has an outer side surface 113 facing the space 101, and the outer side surface 113 is usually used as a braking surface. As shown in FIG. Used as a friction surface to abut.
【０００３】 従来の自転車の車輪用リム１０は、摩耗警告手段付き車輪用リムであり、外側 面１１３のブレーキゴムが当たる部位に、円環状側壁１１の周方向に沿う円環状 の凹溝１１４が形成されている。The conventional bicycle wheel rim 10 is a wheel rim with a wear warning means, and an annular concave groove 114 along the circumferential direction of the annular side wall 11 is provided on a portion of the outer surface 113 where the brake rubber is applied. Is formed.
【０００４】 車輪用リム１０が長期使用されると、外側面１１３のブレーキゴム１３の当た る部位は、ブレーキゴム１３との摩擦によって磨り減らされ、それに伴って、凹 溝１１４も段々浅くなって見えなくなるので、リム１０を更換せよという警告作 用が働く。When the wheel rim 10 is used for a long period of time, the portion of the outer surface 113 that is in contact with the brake rubber 13 is worn away by friction with the brake rubber 13, and accordingly, the concave groove 114 is also gradually reduced. As a result, a warning operation to replace the rim 10 is activated.
【０００５】[0005]
しかしながら、警告作用が働く凹溝１１４は、ブレーキゴム１３が当たる外側 面１１３に形成されているので、ブレーキゴム１３と外側面１１３との間の摩擦 面積を減らし、ブレーキゴム１３のブレーキ効果を減少させるという欠点がある 。 However, since the concave groove 114 on which the warning action works is formed on the outer surface 113 to which the brake rubber 13 contacts, the friction area between the brake rubber 13 and the outer surface 113 is reduced and the braking effect of the brake rubber 13 is reduced. There is a drawback to let.
【０００６】 また、凹溝１１４は路面から飛ばされる土砂に晒される外側面１１３に形成さ れているため、汚物や微細粒子、例えば砂が堆積しやすいので、ブレーキ効果に も悪影響をきたすという欠点がある。In addition, since the concave groove 114 is formed on the outer surface 113 exposed to the earth and sand blown off from the road surface, dirt and fine particles, for example, sand are easily deposited, which has a disadvantage that the braking effect is adversely affected. There is.
【０００７】 本考案は、前記に鑑み、ブレーキ効果を妨げる前記欠点がない摩耗警告手段が ついた自転車の車輪用リムを提供することを目的とする。[0007] In view of the above, an object of the present invention is to provide a rim for a bicycle wheel provided with a wear warning means that does not have the above-mentioned drawbacks that hinder the braking effect.
【０００８】[0008]
前記目的を達成するために、本考案は、円環状の側壁を一対対立させて一体に 連結固定し、一対の側壁の間にタイヤを保持するるための空間を形成してなる自 転車の車輪用リムであって、一対の側壁の互いに向かい合っている内側面の少な くとも一方に窪みが少なくとも一つ形成したことを特徴とする自転車の車輪用リ ムを提供する。 In order to achieve the above object, the present invention provides a bicycle having a pair of annular side walls which are opposed to each other, integrally connected and fixed, and a space for holding a tire is formed between the pair of side walls. A wheel rim for a bicycle, wherein at least one recess is formed in at least one of inner surfaces of a pair of side walls facing each other.
【０００９】 本考案の自転車の車輪用リムは、窪みがブレーキゴムのかからない内側面にあ り、長期使用されると、車輪用リムのブレーキゴムのかかる個所がブレーキゴム との摩擦によって磨り減らされることに伴い、窪みが段々外側から見えるので、 リムを更換せよという警告作用も働く。[0009] The bicycle wheel rim of the present invention has an indentation on the inner surface where the brake rubber is not applied, and when used for a long time, the portion of the wheel rim where the brake rubber is applied is worn down by friction with the brake rubber. As a result, the dents are gradually visible from the outside, and a warning action to replace the rim also works.
【００１０】 また、警告作用が働く窪みは、ブレーキゴムがかからい内側面に形成されてい るので、ブレーキゴムと外側面との間の摩擦面積を減らすことがなく、ブレーキ ゴムのブレーキ効果を減少させない。 また、窪みは路面からの土砂に晒されない内側面に形成されているため、汚物 や微細粒子、例えば砂が堆積しにくいので、ブレーキ効果に影響を与えない。[0010] Further, since the depression on which the warning function works is formed on the inner surface to which the brake rubber is tied, the frictional area between the brake rubber and the outer surface is not reduced, and the braking effect of the brake rubber is reduced. Do not decrease. In addition, since the depression is formed on the inner surface that is not exposed to earth and sand from the road surface, dirt and fine particles, for example, sand, are unlikely to accumulate, so that the braking effect is not affected.
【００１１】 前記構成における窪みは、もちろん円環状側壁の周方向に沿う円環状の凹溝に 形成されても良いが、車輪用リムの強度の角度からみれば、窪みは球面形であっ て、一対の側壁にそれぞれ周方向沿いに等角をあけて複数配置されたものが好ま しい。The depression in the above configuration may of course be formed in an annular groove along the circumferential direction of the annular side wall. However, from the viewpoint of the strength of the wheel rim, the depression is spherical. It is preferable that a plurality of side walls are arranged at regular intervals along the circumferential direction.
【００１２】 本考案の自転車の車輪用リムは、車輪用リムのブレーキゴムによる摩耗によっ て段々見えるようになる窪みの警告作用を向上させるために、窪みの中に着色材 料が充填されたものが好ましい。In the bicycle rim of the present invention, the coloring material is filled in the dent in order to improve the warning action of the dent which becomes gradually visible due to the wear of the wheel rim by the brake rubber. Are preferred.
【００１３】[0013]
図１は本考案に係る自転車の摩耗警告手段付き車輪用リムを説明するための図 である。 車輪用リム２０は、図１に示すように、円環状の周壁２２と、周壁２２の外周 面の両周縁に沿って対立すると共にそれらの間にタイヤ（図示せず）を保持する ための空間２０１をなすように周壁２２と一体に形成された一対の円環状の側壁 ２１とを有する。 FIG. 1 is a diagram for explaining a wheel rim with a wear warning means for a bicycle according to the present invention. As shown in FIG. 1, the wheel rim 20 has a space for holding a tire (not shown) between the annular peripheral wall 22 and both peripheral edges of the outer peripheral surface of the peripheral wall 22. 201 and a pair of annular side walls 21 formed integrally with the peripheral wall 22.
【００１４】 一対の側壁２１は、それぞれ前記空間２０１を背にしている外側面２１３と、 外側面２１３の反対面にあって互いに向かい合っている内側面２１４とがある。 外側面２１３は、通常、ブレーキ面として使用され、即ち、ブレーキがかけられ るとブレーキゴム（図示せず）に当接されて摩擦する面として使用される。一対 の側壁２１の２内側面２１４には、それぞれ周方向沿いに等角をあけた複数の窪 み２１５が配置されている。Each of the pair of side walls 21 has an outer side surface 213 facing the space 201 and an inner side surface 214 opposite to the outer side surface 213 and facing each other. The outer side surface 213 is usually used as a braking surface, that is, a surface that comes into contact with a brake rubber (not shown) and rubs when a brake is applied. On the two inner side surfaces 214 of the pair of side walls 21, a plurality of recesses 215 are respectively arranged at equal angles along the circumferential direction.
【００１５】 本実施形態における自転車の車輪用リム２０は、図２に示すように、窪み２１ ５が、ブレーキゴムのかからない内側面２１４にあるが、車輪用リム２０が長期 使用されると、車輪用リム２０のブレーキゴムのかかる個所がブレーキゴムとの 摩擦によって磨り減らされることに伴い、窪み２１５が段々外側から見えるので 、従来の車輪用リム１０の凹溝１１４と同様に、リム２０を更換せよという警告 作用も働く。As shown in FIG. 2, the bicycle wheel rim 20 according to the present embodiment has a recess 215 on the inner side surface 214 where the brake rubber is not applied. As the portion of the brake rim 20 where the brake rubber is applied is worn away by friction with the brake rubber, the recess 215 is gradually seen from the outside. Therefore, the rim 20 is replaced similarly to the groove 114 of the conventional wheel rim 10. A warning action to work also works.
【００１６】 また、警告作用が働く窪み２１５は、ブレーキゴムがかからない内側面２１４ に形成されているので、ブレーキゴムと外側面２１３との間の摩擦面積を減らす ことなく、ブレーキゴムのブレーキ効果を減少させない。窪み２１５は路面から 飛ばされる土砂に晒されない内側面２１４に形成されているたため、汚物や微細 粒子、例えば砂が堆積しにくいので、ブレーキ効果にも影響をきたさない。Further, since the depression 215 on which the warning function works is formed on the inner side surface 214 to which the brake rubber is not applied, the braking effect of the brake rubber can be reduced without reducing the friction area between the brake rubber and the outer side surface 213. Do not decrease. Since the depression 215 is formed on the inner surface 214 that is not exposed to the earth and sand that is blown off the road surface, dirt and fine particles, for example, sand, are unlikely to accumulate, so that the braking effect is not affected.
【００１７】 また、本実施形態における窪み２１５は球面形であって、一対の側壁２１にそ れぞれ周方向沿いに等角をあけて複数配置されているが、この構成に限らず、例 えば星形や三角形でも良く、ひいては、複数の小さな窪みでなく、一つや複数の 円環状側壁２１の周方向に沿う円環状の凹溝に形成されものであつてもい。In addition, the depression 215 in the present embodiment is spherical, and a plurality of depressions 215 are arranged on the pair of side walls 21 at regular intervals along the circumferential direction. However, the present invention is not limited to this configuration. For example, the shape may be a star or a triangle, and may be formed not in a plurality of small depressions but in an annular groove along the circumferential direction of one or a plurality of annular side walls 21.
【００１８】 窪み２１５の中には、赤や黄などの顕著な色に着色された材料２１６が充填さ れている。このため、車輪用リム２０のブレーキゴムによる摩耗によって、窪み ２１５が少しでも露出した場合、着色された材料２１６が充填されているため、 窪み２１５が著しく見えるので、警告作用を一層向上させることができる。The recess 215 is filled with a material 216 colored in a remarkable color such as red or yellow. For this reason, when the depression 215 is slightly exposed due to wear of the wheel rim 20 due to the brake rubber, the depression 215 is markedly visible because the colored material 216 is filled, so that the warning action can be further improved. it can.
【００１９】[0019]
本考案における警告作用が働く窪み２１５はブレーキゴムがかからない内側面 ２１４に形成されているため、ブレーキゴムと外側面２１３との間の摩擦面積を 減らすことがなく、ブレーキゴムのブレーキ効果を減少しない。215 recess acts warning effect in the present invention because it is formed on the inner surface 214 not applied brake rubber, without reducing the friction area between the blanking Rekigomu and the outer surface 213, it does not reduce the braking effect of the brake rubber .
【００２０】 また、窪み２１５は路面から飛ばされる土砂に晒されない内側面２１４に形成 されているめため、汚物や微細粒子、例えば砂が堆積しにくいので、ブレーキ効 果にも影響をきたさない。Further, since the depression 215 is formed on the inner side surface 214 which is not exposed to earth and sand blown off the road surface, dirt and fine particles, for example, sand, are unlikely to accumulate, so that the braking effect is not affected.
【００２１】 更に、窪み２１５の中に、着色材料２１６を充填することで、車輪用リムのブ レーキゴムによる摩耗によって段々見えるようになる窪みの警告作用を向上させ ることができる。Further, by filling the recess 215 with the coloring material 216, it is possible to improve a warning effect of the recess which becomes gradually visible due to wear of the wheel rim due to the brake rubber.
