Description
【０００１】[0001]
本考案は車輪本体を合成樹脂により一体成形するようにした自転車用車輪に関 する。 The present invention relates to a bicycle wheel in which a wheel body is integrally molded of synthetic resin.
【０００２】[0002]
自転車用車輪には、ハブ体に外嵌する筒状の取付部と、該取付部から径方向に 放射状に突出した複数のスポーク部と、各スポーク部の外端と連結する環状のリ ム部とを有する車輪本体を合成樹脂により一体成形するようにしたものがある。 ところが、従来では各スポーク部は取付部とスポーク部とを連結する板状のス ポーク本体を備えるが、従来ではこの板状の各スポーク本体は、単に車軸方向に 平行な板状であった。 BACKGROUND ART A bicycle wheel has a tubular mounting portion that is externally fitted to a hub body, a plurality of spoke portions that radially project from the mounting portion, and an annular rim portion that is connected to the outer ends of the spoke portions. There is one in which a wheel body having a and is integrally formed of synthetic resin. However, conventionally, each spoke portion is provided with a plate-shaped spoke body that connects the attachment portion and the spoke portion, but in the past, each plate-shaped spoke body was simply a plate shape that was parallel to the axle direction.
【０００３】[0003]
自転車に乗った場合、合成樹脂製の車輪本体の各スポーク部に相当大きな圧縮 力が作用するが、スポーク部のスポーク本体は単に車軸方向に平行な板状であっ たため、圧縮力によって各スポーク部が弾性変形のために順次同方向に弯曲変形 して、座屈を起こし易く、このため車輪のスムーズな回転ができなくなる惧れが 大であった。 When riding a bicycle, a considerable amount of compressive force acts on each spoke part of the synthetic resin wheel body, but since the spoke body of the spoke part is simply a plate shape parallel to the axle direction, each spoke part is compressed by the compressive force. However, due to elastic deformation, the wheels tend to bend in the same direction one after another, and buckling is likely to occur, and there was a great danger that the wheels could not rotate smoothly.
【０００４】 本考案は上記問題点に鑑み、相当大きな圧縮力を受けても座屈を起こす惧れが なく、スムーズに回転できる自転車用車輪を提供することを目的とする。In view of the above problems, it is an object of the present invention to provide a bicycle wheel that is not likely to buckle even when subjected to a considerably large compressive force and can be smoothly rotated.
【０００５】[0005]
この技術的課題を解決するための本考案の技術的手段は、ハブ体1 に外嵌する 筒状の取付部5 と、該取付部5 から突出された複数のスポーク部6 と、各スポー ク部6 の外端と連結する環状のリム部7 とを一体に有する車輪本体4 が合成樹脂 により一体成形された自転車用車輪において、前記各スポーク部6 は、取付部5 とスポーク部6 とを連結しかつ車軸方向に対して傾斜した板面を有するスポーク 本体15を備え、この各スポーク本体15は、隣り合うスポーク本体15が互いにハの 字状に傾斜して順次周方向に並ぶように、交互に逆向きに傾斜されている点にあ る。 The technical means of the present invention for solving this technical problem is to provide a tubular mounting portion 5 which is externally fitted to the hub body 1, a plurality of spoke portions 6 protruding from the mounting portion 5, and each spoke. In a bicycle wheel in which a wheel body 4 integrally having an annular rim portion 7 connected to the outer end of the portion 6 is integrally molded of synthetic resin, each spoke portion 6 includes a mounting portion 5 and a spoke portion 6. The spoke main bodies 15 that are connected to each other and have a plate surface that is inclined with respect to the axle direction are provided, and each of the spoke main bodies 15 is arranged so that adjacent spoke main bodies 15 are inclined in a V shape and are sequentially arranged in the circumferential direction. The points are alternately inclined in opposite directions.
【０００６】[0006]
自転車に乗った場合、車輪の回転に伴なって車輪本体4 の各スポーク部6 に順 次相当大きな圧縮力がかかる。しかし、各スポーク部6 が取付部5 とリム部7 と の間で相当大きな圧縮力を受けても、その圧縮力を、隣り合うスポーク本体15が 互いにハの字状に傾斜して受けて、互いに突張り合うため、圧縮力によって各ス ポーク部6 が弾性変形によって順次同方向に弯曲変形するようなことがなくなる 。 When riding a bicycle, a large amount of compressive force is applied to each of the spokes 6 of the wheel body 4 in sequence as the wheel rotates. However, even if each spoke portion 6 receives a considerably large compressive force between the mounting portion 5 and the rim portion 7, the adjacent spoke main bodies 15 receive the compressive force while being inclined in a V-shape, Since the two spokes are urged against each other, the spokes 6 are not elastically deformed and sequentially deformed in the same direction by a compressive force.
【０００７】 また、各スポーク本体15の両面に、反射体18を添設することにより、スポーク 本体15が車軸方向に対して傾斜しているため、その反射体18を前後左右のどの方 向からも容易に目視することができる。Further, since the reflectors 18 are attached to both sides of each spoke body 15 so that the spoke body 15 is inclined with respect to the axial direction, the reflectors 18 can be placed in any direction from front, rear, left and right. Is also easily visible.
【０００８】[0008]
以下、本考案の図示の実施例に従って説明すると、図１乃至図４において、１ は自転車用車輪のハブ体で、ハブ胴2 と、ハブ胴2 に対して左右一対のベアリン グを介して軸廻りに回動自在に保持されたハブ軸3 とを備える。 ４は車輪本体で、ハブ体1 に外嵌する筒状の取付部5 と、該取付部5 から径方 向に放射状に突出された複数のスポーク部6 と、各スポーク部6 の外端と連結す るリム部7 とを一体に有し、車輪本体4 はハブ体1 をインサートした状態で合成 樹脂により一体成形されている。 1 to 4, reference numeral 1 denotes a hub body of a bicycle wheel, which includes a hub barrel 2 and a pair of left and right bearings with respect to the hub barrel 2. A hub shaft (3) rotatably held around the hub shaft (3). Reference numeral 4 denotes a wheel body, which is a tubular mounting portion 5 which is externally fitted to the hub body 1, a plurality of spoke portions 6 radially protruding from the mounting portion 5, and outer ends of the respective spoke portions 6. It integrally has a rim portion 7 to be connected, and the wheel body 4 is integrally molded of synthetic resin with the hub body 1 inserted.
【０００９】 取付部5 は、内筒体11と外筒体12と筒体11,12 間に放射状に配置された複数の 連結体13とを備えて成り、内筒体11はハブ胴2 に外嵌固着されている。外筒体12 は内筒体11の周囲を同心状に取囲み、この外筒体12にスポーク部6 が放射状に突 出されている。連結体13は周方向に等間隔をおいて複数あり、夫々内筒体11と外 筒体12とを径方向に連結している。The mounting portion 5 includes an inner tubular body 11, an outer tubular body 12, and a plurality of connecting bodies 13 radially arranged between the tubular bodies 11, 12, and the inner tubular body 11 is attached to the hub barrel 2. It is fixed by external fitting. The outer cylinder 12 surrounds the inner cylinder 11 concentrically, and the spokes 6 are radially projected from the outer cylinder 12. A plurality of connecting bodies 13 are arranged at equal intervals in the circumferential direction, and respectively connect the inner tubular body 11 and the outer tubular body 12 in the radial direction.
【００１０】 前記スポーク部6 は偶数本（図例では10本) 設けられ、各スポーク部6 はリム 部7 から取付部5 に向けて車輪径方向に配置されると共に、車輪全周に亘って周 方向等間隔おきに配置されている。また各スポーク部6 は、図５及び図６にも示 す如く取付部5 とスポーク部6 とを連結しかつ車軸方向に対して傾斜した板面を 有するスポーク本体15を備えると共に、スポーク本体15の幅方向両端から車軸方 向に垂直な方向に折曲した一対のリブ16を備え、一対のリブ16は互いに逆方向に 折曲されている。前記各スポーク部6 のスポーク本体15は、交互に逆向きに傾斜 されており、隣り合うスポーク本体15が互いにハの字状に傾斜して順次周方向に 並んでいる。また各スポーク本体15は、車軸方向に対する傾斜が取付部5 側より もスポーク部6 側の方がやや大になるように、取付部5 からスポーク部6 に向け て時計廻り又は反時計廻りに若干ねじれた状態になっている。The spokes 6 are provided in an even number (10 in the illustrated example), and the spokes 6 are arranged in the wheel radial direction from the rim 7 to the mounting 5 and are arranged over the entire circumference of the wheel. They are arranged at equal intervals in the circumferential direction. Further, as shown in FIGS. 5 and 6, each spoke portion 6 has a spoke body 15 that connects the attachment portion 5 and the spoke portion 6 and has a plate surface inclined with respect to the axle direction. It has a pair of ribs 16 bent from both ends in the width direction in a direction perpendicular to the axle direction, and the pair of ribs 16 are bent in mutually opposite directions. The spoke main bodies 15 of the respective spoke portions 6 are alternately inclined in opposite directions, and the adjacent spoke main bodies 15 are inclined in a V shape and are sequentially arranged in the circumferential direction. In addition, each spoke body 15 is slightly rotated clockwise or counterclockwise from the mounting portion 5 to the spoke portion 6 so that the inclination with respect to the axle direction is slightly larger on the spoke portion 6 side than on the mounting portion 5 side. It is twisted.
【００１１】 前記各スポーク本体15の両面は反射体取付面とされ、ここに反射テープ、反射 シート又は反射板により構成した反射体18が添設されている。Both sides of each of the spoke bodies 15 serve as reflector mounting surfaces, and reflectors 18 formed of a reflective tape, a reflective sheet, or a reflective plate are attached to the surfaces.
【００１２】[0012]
本考案によれば、各スポーク部6 は、取付部5 とスポーク部6 とを連結しかつ 車軸方向に対して傾斜した板面を有するスポーク本体15を備え、この各スポーク 本体15は、隣り合うスポーク本体15が互いにハの字状に傾斜して順次周方向に並 ぶように、交互に逆向きに傾斜されているので、各スポーク部6 が取付部5 とリ ム部7 との間で相当大きな圧縮力を受けても、その圧縮力を、隣り合うスポーク 本体15が互いにハの字状に傾斜して受けて、互いに突張り合うため、圧縮力によ って各スポーク部6 が弾性変形のために順次同方向に弯曲変形するようなことが なくなり、スポーク部6 が座屈を起こす惧れを効果的に防止することができ、相 当大きな圧縮力を受けても、車輪をスムーズに回転させることが可能になる。 According to the present invention, each spoke portion 6 is provided with a spoke body 15 that connects the attachment portion 5 and the spoke portion 6 and has a plate surface inclined with respect to the axle direction, and the spoke bodies 15 are adjacent to each other. Since the spoke main bodies 15 are alternately inclined so that they are inclined in a V shape and are aligned in the circumferential direction, the respective spoke parts 6 are arranged between the mounting part 5 and the rim part 7. Even if a considerably large compressive force is applied, the adjacent spoke main bodies 15 are inclined in a V-shape and are thrust against each other, so that the spokes 6 are elastically deformed by the compressive force. Therefore, it is possible to effectively prevent the spokes 6 from buckling because they do not bend in the same direction one after the other, and the wheels can be made smooth even when subjected to a relatively large compressive force. It becomes possible to rotate.
【００１３】 また、スポーク部6 が周方向に略等間隔をおいて偶数本設けられているので、 隣り合うスポーク部6 のスポーク本体15を全周に亘って交互に逆方向に傾斜させ ることができ、スポーク部6 をより確実に座屈防止することができる。 また、各スポーク部6 がスポーク本体15の幅方向両端から軸方向に垂直な方向 に折曲した一対のリブ16を備えるので、リブ16によってスポーク部6 の剛性を高 め、これによってもスポーク部6 の座屈を防止できる。Further, since the even number of the spoke portions 6 are provided at substantially equal intervals in the circumferential direction, the spoke bodies 15 of the adjacent spoke portions 6 are alternately inclined in the opposite direction over the entire circumference. Therefore, the spokes 6 can be more reliably prevented from buckling. In addition, since each spoke portion 6 is provided with a pair of ribs 16 bent in the direction perpendicular to the axial direction from both widthwise ends of the spoke body 15, the ribs 16 increase the rigidity of the spoke portion 6, which also increases the spoke portion. Buckling of 6 can be prevented.
【００１４】 また、各スポーク本体15の両面に、反射体18を添設することにより、スポーク 本体15は車軸方向に対して傾斜しているため、車輪本体4 を前後左右のどの方向 から見ても反射体18を見ることができ、反射体18の機能を十分に発揮させること ができ、自転車走行の安全を向上させ得る。In addition, since the spoke bodies 15 are inclined with respect to the axle direction by providing the reflectors 18 on both sides of each spoke body 15, when the wheel body 4 is viewed from any direction of front, rear, left and right. Also, the reflector 18 can be seen, and the function of the reflector 18 can be fully exerted to improve the safety of bicycle riding.
