Description

本発明は、車輪構造に関するもので、特にリムおよびハブが複数のスポークの双方向直立ネジで結合される時、リムは、使用において、車輪軸中心に合わさることで応力が平均化するため、リム全体の構造強度を大幅に向上、安定させ、変形しにくい新しい構造デザインに係る。 The present invention relates to a wheel structure, especially when the rim and hub are connected by bidirectional upright screws on multiple spokes, the rim is in use because the stress is averaged by aligning with the center of the wheel axis. It is related to a new structural design that greatly improves and stabilizes the overall structural strength and is resistant to deformation.

一般の車輪は車椅子または自転車に応用されて使用され、時代が進むと共に車輪は各種異なる部品が強度を向上させて進歩してきた。公知の車輪組構造は、主に外周のリム、中心ハブおよびリムとハブの間で連結する複数のスポークから構成される。該リム内壁は複数の穿孔が穿設され、且つ各スポーク一端はハブに固定接続し、またスポーク別一端は穿孔を設けてリム内に挿入し、固定部材でスポークと相互に固定する。但し、リムが加工される時、大抵はアルミ押出方式の製造成形が採用されているが、該スポークに固定部材を加えてナットで締めると、スポークを締めたナットとリム内壁で接合した接合面が円弧面を形成し、固定部材およびナットがリムの穿孔外縁端面と完全に合わさることができない。場合によっては偏ってしまい受ける力が不均等になり、車輪軸中心に正確に合わせることができず、リム全体の構造が安定固定できない。その他として、リム、ハブおよび複数のスポークを有し、そのうち、該リム内側には複数の組立部材を設け、各組立部材にはリム内に設置する内部埋込端、リム内側で露出する結合端を設ける。各スポークはハブの固設端に設け、且つ別一端には組立部材の結合端と相互に嵌合する嵌合槽を設ける（例として特許文献１参照）。しかしながら、該公知のリム内側には複数の組立部材を設けネジ止めではなく結合し、嵌合連結方式だけなので、構造強度が不足する。そのため、仮に長期に車輪体が振動状態にあると、嵌合連結部材が外れたり折れたりしやすい。 General wheels are applied to wheelchairs or bicycles, and as the times progress, various different parts of wheels have improved in strength. The known wheel assembly structure is mainly composed of an outer peripheral rim, a central hub and a plurality of spokes connecting between the rim and the hub. The inner wall of the rim is perforated with a plurality of perforations, one end of each spoke is fixedly connected to the hub, and one end of each spoke is perforated and inserted into the rim, and is fixed to each other with the spokes by a fixing member. However, when the rim is processed, aluminum extrusion method manufacturing molding is usually adopted, but if a fixing member is added to the spoke and tightened with a nut, the joint surface joined by the nut with the spoke tightened and the inner wall of the rim. Form an arcuate surface, and the fixing member and nut cannot be perfectly aligned with the perforated outer edge end face of the rim. In some cases, it will be biased and the force received will be uneven, it will not be possible to accurately align it with the center of the wheel shaft, and the structure of the entire rim will not be able to be stably fixed. In addition, it has a rim, a hub, and a plurality of spokes, of which a plurality of assembly members are provided inside the rim, and each assembly member has an internal embedded end installed inside the rim and a joint end exposed inside the rim. Is provided. Each spoke is provided at the fixed end of the hub, and a fitting tank that is mutually fitted with the connecting end of the assembly member is provided at the other end (see Patent Document 1 as an example). However, since a plurality of assembly members are provided inside the known rim and are connected instead of being screwed, and only a fitting connection method is used, the structural strength is insufficient. Therefore, if the wheel body is in a vibrating state for a long period of time, the fitting connecting member is likely to come off or break.

台湾特許公告Ｍ４４２２８０『自転車リム組立装置』Taiwan Patent Notice M442280 "Bicycle Rim Assembly Device"

以上の現象から、本発明者は、長年の制作経験にもとづき、使用に際し、車輪軸中心に合わさって応力が平均化するものを考案し、本発明のリム全体の構造強度が大幅に向上し、且つ構造が安定し、変形しにくいの車輪構造を提供することを本発明の目的とする。 From the above phenomenon, the present inventor devised a device in which the stress is averaged according to the center of the wheel shaft when used, based on many years of production experience, and the structural strength of the entire rim of the present invention is greatly improved. Moreover, it is an object of the present invention to provide a wheel structure having a stable structure and not easily deformed.

即ち、本発明の主な目的は、車輪構造を提供する。その解決しようとする課題として、公知リムの加工時に大抵はアルミ押出方式の製造成形が採用されているが、該スポークに固定部材を加えてナットで締めた時、スポークを固定したナットとリムの内壁が接合する接合面は円弧面を形成し、固定部材およびナットリムの穿孔外縁端面と完全に合わさることができない。場合によっては偏ってしまい受ける力が不均等になり、車輪軸中心に合わせることができず、リム全体の構造が安定固定できない問題点を改善する。 That is, a main object of the present invention is to provide a wheel structure. As a problem to be solved, aluminum extrusion manufacturing molding is usually adopted when processing a known rim, but when a fixing member is added to the spoke and tightened with a nut, the nut and the rim on which the spoke is fixed are used. The joint surface to which the inner walls join forms an arc surface and cannot be completely aligned with the perforated outer edge end surface of the fixing member and nut rim. In some cases, the force received will be uneven due to bias, and it will not be possible to align with the center of the wheel axis, which will improve the problem that the structure of the entire rim cannot be stably fixed.

課題を解決するための手段として、それはリムを有する。その内縁周辺面には環状に複数の貫通部を設け、該リム内部中心箇所にはハブを設ける。該ハブは該リムの各該貫通部に対応する両側に、相対設置する内ネジ孔をそれぞれ設け、該貫通部および該内ネジ孔は複数のスポークによって、それぞれ相対交錯して結合組立する。そのうち該スポークは第一連結ネジ段および第二連結ネジ段をそれぞれ備え、該第一連結ネジ段は該ハブ両側の内ネジ孔に挿入した後、ネジ組部材でネジ止め結合し、該第二連結ネジ段は該リムの各該貫通部に挿入した後、次に第一ナット部材および第二ナット部材で該第二連結ネジ段に相対ネジ止めし、更に該第一ナット部材および該第二ナット部材を該貫通部周辺縁内外端面位置に対応ネジ止めする。複数の当接止め端面は該リムの内縁周辺面にそれぞれ成形し、更に各該スポークの縦方向連結位置に相対して位置する。それは即ち、一ユニットのスポークが一ユニットの当接止め端面に縦方向に位置合わせすることである。そのうち各該スポークの中心軸線と該対応する当接止め端面の相対角度は、９０度の垂直縦方向面であり、各該当接止め端面の間は角度転換区をそれぞれ成形して該第一ナット部材および該第二ナット部材で該スポークの該第二連結ネジ段に固定し、更に該リムにしっかりと固定する時、該第一ナット部材および該第二ナット部材の該リムに相対する接触端面は相互に対応する該当接止め端面で完全に接触して合わさる。 As a means to solve the problem, it has a rim. A plurality of penetrating portions are provided in an annular shape on the peripheral surface of the inner edge, and a hub is provided at the central portion inside the rim. The hub is provided with internal screw holes to be relatively installed on both sides corresponding to the through portions of the rim, and the through portions and the internal screw holes are connected and assembled by a plurality of spokes, respectively. Among them, the spoke is provided with a first connecting screw step and a second connecting screw step, respectively, and the first connecting screw step is inserted into the internal screw holes on both sides of the hub, and then screwed together with a screw assembly member to form the second. After inserting the connecting screw step into each through portion of the rim, the first nut member and the second nut member are then screwed relative to the second connecting screw step, and then the first nut member and the second nut member are screwed to the second connecting screw step. The nut member is screwed to the position of the inner and outer end faces of the peripheral edge of the penetrating portion. The plurality of contact stop end faces are formed on the inner peripheral peripheral surfaces of the rim, respectively, and are further located relative to the vertical connection positions of the spokes. That is, the spokes of one unit are vertically aligned with the abutting end face of one unit. The relative angle between the central axis of each spoke and the corresponding contact end face is a vertical vertical plane of 90 degrees, and an angle conversion zone is formed between each corresponding stop end face to form the first nut. When the member and the second nut member are fixed to the second connecting screw step of the spoke and further firmly fixed to the rim, the contact end faces of the first nut member and the second nut member facing the rim. Are in complete contact and mating at the corresponding anchoring end faces that correspond to each other.

これらの新しいデザインによって、本発明は、各該スポークの中心軸線、該リムの対応する当接止め端面および該ハブの相対配置角度は垂直縦方向面であり、該第一ナット部材および該第二ナット部材によって該スポークの該第二連結ネジ段に固定し、更に該リムにしっかりと固定する時、該第一ナット部材および該第二ナット部材の該リムに相対する接触端面は相対する該当接止め端面に完全に合わさり、該リムおよび該ハブが該複数のスポークの双方向直立ネジで結合される時、該リムは、使用において、車輪軸中心に合わさることで応力が平均化するため、本発明の車輪全体構造強度が大輻に向上して構造が安定し、変形しにくい。 With these new designs, the present invention allows the relative placement angle of the central axis of each spoke, the corresponding abutting end face of the rim and the hub to be a vertical longitudinal plane, the first nut member and the second. When fixed to the second connecting screw step of the spoke by the nut member and further firmly fixed to the rim, the first nut member and the contact end faces of the second nut member facing the rim are in contact with each other. When fully fitted to the retaining end face and the rim and the hub are joined by bidirectional upright screws on the multiple spokes, the rim will, in use, be aligned with the center of the wheel axis to even out the stress.
