Description

本考案は自転車用車輪に係り、詳しくは、タイヤの着脱作業を簡単にした自転車用車輪に関するものである。 The present invention relates to a bicycle wheel, and more particularly to a bicycle wheel in which a tire can be easily attached and detached.

従来、自転車用車輪の一例として図５に示すものが提案されている。この自転車用車輪は、ハブ１００の両端部に形成したハブ鍔１０１とリム１０２との間に多数の金属線材からなるスポーク１０３を配設し、これらスポーク１０３によってハブ１００とリム１０２とを一体に結合するとともに、リム１０２の外周部にチューブ（図示省略）を内蔵したタイヤ１０４を装着してある（たとえば特許文献１）。 Conventionally, what is shown in FIG. 5 as an example of a bicycle wheel has been proposed. In this bicycle wheel, spokes 103 made of a number of metal wires are disposed between a hub collar 101 and rims 102 formed at both ends of the hub 100, and the hub 100 and the rim 102 are integrated with each other by the spokes 103. In addition, a tire 104 including a tube (not shown) is attached to the outer periphery of the rim 102 (for example, Patent Document 1).

また、従来の自転車用車輪の他の例として図６に示すものが提案されている。この自転車用車輪は、ハブ１００の両端部に形成したハブ鍔１０１とリム１０２との間に複数本の軽合金製の板状連結部材１０５を配設し、これら板状連結部材１０５によってハブ１００とリム１０２とを一体に結合するとともに、リム１０２の外周部にチューブ（図示省略）を内臓したタイヤ１０４を装着してある（たとえば特許文献２）。 Further, another example of a conventional bicycle wheel has been proposed as shown in FIG. In this bicycle wheel, a plurality of light alloy plate-like connecting members 105 are disposed between hub collars 101 and rims 102 formed at both ends of the hub 100, and the hub 100 is provided by these plate-like connecting members 105. And the rim 102 are integrally coupled, and a tire 104 having a tube (not shown) is attached to the outer periphery of the rim 102 (for example, Patent Document 2).

特開２００５−１４７４９号公報。JP-A-2005-14749. 特開平５−２８６３０１号公報。JP-A-5-286301.

ところが、前記特許文献１および２に記載されている自転車用車輪では、タイヤ・チューブの交換あるいはパンクの修理などに際してなされるタイヤ１０４の脱着が困難である。すなわち、タイヤ１０４の脱着に際しては、専用のヘラ状の金属製工具が必要であるばかりか、熟練した手作業が要求される。そのため、自転車所有者による自宅でのタイヤ１０４の脱着は敬遠され、修理業者に委ねているのが現状である。したがって、自宅でのタイヤ・チューブの交換やパンクの修理が必要な場合には、自転車を修理店まで歩いて押し進めなければならない。また、修理店では、当然、熟練した作業者によってタイヤ１０４の脱着がなされるものの、その作業には、前記のように専用のヘラ状の金属製工具が必要である上に、煩雑な手間が要求されるので、たとえ熟練した作業者といえども必ずしも脱着が容易であるとはいえない。 However, in the bicycle wheel described in Patent Documents 1 and 2, it is difficult to attach and detach the tire 104 when exchanging tires and tubes or repairing punctures. That is, when attaching and detaching the tire 104, not only a dedicated spatula-shaped metal tool is required but also a skilled manual operation is required. Therefore, the current situation is that the bicycle owner is refrained from attaching and detaching the tire 104 at home and leaves it to a repairer. Therefore, if you need to replace tires and tubes at home or repair punctures, you must walk your bicycle to the repair shop. Of course, in a repair shop, the tire 104 is attached and detached by a skilled worker, but this work requires a dedicated spatula-shaped metal tool as described above, and is troublesome. Because it is required, even a skilled worker is not always easy to detach.

本考案は、このような問題を解決するものであって、その目的とするところは、タイヤ・チューブの交換あるいはパンクの修理などに際してなされるタイヤの脱着を、修理業者に委ねなくても自転車所有者サイドで簡単に行うことができる自転車用車輪を提供することにある。 The present invention solves these problems, and the purpose of the present invention is to own a bicycle without leaving the repair / replacement of tires to be removed or replaced when replacing tires / tubes or repairing punctures. An object of the present invention is to provide a bicycle wheel that can be easily performed on the side of a person.

本考案は、タイヤと該タイヤに内蔵されたチューブの両者が装着されるリムと、車軸を回転自在に挿通して軸方向の移動を不能に保持するハブとを備え、前記リムとハブとが連結部材により一体に結合されている自転車用車輪において、前記リムと連結部材が一体に成形されて軸方向に二分割された一対の単体からなる複合体によって構成されており、この複合体が第１締結部材により分離可能に締結されているとともに、該複合体の基端部が第２締結部材により前記ハブに着脱可能に結合されていることを特徴としている。 The present invention includes a rim on which both a tire and a tube built in the tire are mounted, and a hub that rotatably inserts an axle and holds axially incapable of movement. In the bicycle wheel integrally connected by the connecting member, the rim and the connecting member are integrally formed, and are constituted by a pair of single bodies divided into two in the axial direction. The composite body is detachably fastened by one fastening member, and the base end portion of the composite is detachably coupled to the hub by a second fastening member.

これによれば、第１締結部材の締結弛緩によりリムと連結部材の軸方向寸法を拡大でき、第１締結部材の締結解除によりリムと連結部材を軸方向に分離できるので、タイヤの脱着を簡単に行うことができる。すなわち、タイヤの耳部とリムの耳部との係合解除およびリムの耳部に対するタイヤの耳部の係合を、従来のように専用のヘラ状の金属製工具を使用することなく、指先による単純な作業によって簡単に行うことができ、タイヤに内蔵されているチューブの脱着も簡単に行い得る。 According to this, the axial dimensions of the rim and the connecting member can be enlarged by fastening and loosening the first fastening member, and the rim and the connecting member can be separated in the axial direction by releasing the fastening of the first fastening member, so that the tire can be easily attached and detached. Can be done. That is, the fingertip can be used to release the engagement between the ear portion of the tire and the ear portion of the rim and the engagement of the ear portion of the tire with the ear portion of the rim without using a dedicated spatula-shaped metal tool as in the prior art. It can be easily performed by a simple operation, and the tube built in the tire can be easily attached and detached.

また、本考案は、連結部材をディスク状に形成することが好ましい。これによると、自転車用車輪の強度を向上させて、強靭な自転車用車輪を提供できる。 In the present invention, the connecting member is preferably formed in a disk shape. According to this, the strength of the bicycle wheel can be improved and a strong bicycle wheel can be provided.

さらに、本考案は、連結部材を複数のアーム部によって構成してもよい。これによると、所定の強度を確保した上で自転車用車輪の軽量化を図るとともに、使用材料を節減できる。 Further, in the present invention, the connecting member may be constituted by a plurality of arm portions. According to this, while ensuring predetermined intensity | strength, while aiming at the weight reduction of the wheel for bicycles, material to be used can be saved.

本考案によれば、第１締結部材の締結弛緩によるリムの軸方向寸法拡大または第１締結部材の締結解除によるリムの軸方向分離により、タイヤおよびチューブの脱着を簡単に行うことができるので、たとえば、タイヤを交換したい場合やパンクを確認した場合などにおいて、その都度修理業者に委ねることなく自転車所有者サイドの素人でも簡単にタイヤ・チューブを脱着できる。また、修理店での熟練した作業者によるタイヤの脱着がより一層簡単になり、いずれの場合でも、従来必要とされていた専用のヘラ状の金属製工具が不要で、モンキーやスパナ類などの使用頻度の高い一般的な工具によって簡単に脱着作業を実行できる。 According to the present invention, the tire and the tube can be easily attached and detached by expanding the axial dimension of the rim by loosening the first fastening member or by separating the axial direction of the rim by releasing the fastening of the first fastening member. For example, when replacing a tire or confirming a puncture, an amateur on the bicycle owner's side can easily attach and detach tires and tubes without entrusting them to a repairer each time. In addition, tire removal and removal by skilled workers at repair shops is even easier, and in any case, a special spatula-shaped metal tool that was required in the past is unnecessary, such as monkeys and spanners. The detachment work can be easily performed with a general tool that is frequently used.

以下、本考案に係る自転車用車輪の好ましい一実施形態を図面にしたがって説明する。
図１は本考案に係る自転車用車輪の一実施形態を示す側面図、図２は図１のＡ−Ａ線に沿う拡大断面図、図３はリムと連結部材の軸方向寸法を拡大した状態を示す拡大断面図である。 Hereinafter, a preferred embodiment of a bicycle wheel according to the present invention will be described with reference to the drawings.
1 is a side view showing an embodiment of a bicycle wheel according to the present invention, FIG. 2 is an enlarged cross-sectional view taken along the line AA of FIG. 1, and FIG. FIG.

図１，図２において、自転車用車輪１は、タイヤ２と該タイヤ２に内蔵されたチューブ３の両者２，３を外周部に巻回して装着するリム４と、車軸５を回転自在に挿通してこれを軸方向の移動を不能に保持するハブ６とを備え、リム４とハブ６とを連結部材７により一体に結合することによって構成されている。そして、タイヤ２の一対の耳部２ａ，２ｂをリム４の一対の耳部４ａ，４ｂに係合させることによって、リム４の外周部にタイヤ２が巻回保持されている。 1 and 2, a bicycle wheel 1 includes a tire 2 and a rim 4 on which a tube 3 built in the tire 2 is wound around an outer periphery, and a rim 4 and an axle 5 are rotatably inserted. The rim 4 and the hub 6 are integrally connected to each other by a connecting member 7. Then, by engaging the pair of ears 2 a and 2 b of the tire 2 with the pair of ears 4 a and 4 b of the rim 4, the tire 2 is wound and held around the outer periphery of the rim 4.

前記リム４は周知の環状のもので、連結部材７はディスク状に形成されている。連結部材７がディスク状に形成されていることにより、自転車用車輪１の強度を向上させて、強靭な自転車用車輪を提供できる。また、リム４とディスク状の連結部材７は、たとえばアルミニューム系の軽合金によって一体に成形され、軸方向（図２の矢印Ｗの方向）に二分割された一対の単体８ａ，８ｂからなる複合体８によって構成されている。 The rim 4 is a well-known ring shape, and the connecting member 7 is formed in a disk shape. By forming the connecting member 7 in a disc shape, the strength of the bicycle wheel 1 can be improved and a tough bicycle wheel can be provided. The rim 4 and the disk-shaped connecting member 7 are integrally formed of, for example, an aluminum-based light alloy, and include a pair of single bodies 8a and 8b that are divided into two in the axial direction (the direction of the arrow W in FIG. 2). The composite 8 is used.

前記複合体８は、車軸５を中心として一点鎖線で描かれる円Ｒ上に円周方向等間隔で設定される複数箇所（たとえば６箇所）において、ディスク状の連結部材７におけるリム４側に偏った部位を複数組（たとえば６組）のボルト・ナットからなる第１締結部材９によって一対の単体８ａ，８ｂを締結することによって構成される。また、一方の単体８ａにおけるディスク状の連結部材７の基端部が複数組のボルト・ナットからなる第２締結部材１０によってハブ６のハブ鍔６ａに着脱可能に結合され、他方の単体８ｂにおけるディスク状の連結部材７の基端部が前記第２締結部材１０によってハブ６のハブ鍔６ｂに着脱可能に結合されている。なお、図中１１はバルブを示し、チューブ３内への空気圧入時に使用される。また、１２は第２締結部材１０におけるボルトを挿通しているスリーブである。 The composite 8 is biased toward the rim 4 side of the disk-shaped connecting member 7 at a plurality of locations (for example, 6 locations) set at equal intervals in the circumferential direction on a circle R drawn with a one-dot chain line around the axle 5. This portion is configured by fastening a pair of single bodies 8a and 8b with a first fastening member 9 comprising a plurality of sets (for example, 6 sets) of bolts and nuts. Further, the base end portion of the disk-like connecting member 7 in one single unit 8a is detachably coupled to the hub collar 6a of the hub 6 by a second fastening member 10 composed of a plurality of sets of bolts and nuts, and the other single unit 8b has A base end portion of the disk-shaped connecting member 7 is detachably coupled to the hub collar 6b of the hub 6 by the second fastening member 10. In the figure, reference numeral 11 denotes a valve, which is used when the air pressure enters the tube 3. Reference numeral 12 denotes a sleeve through which a bolt in the second fastening member 10 is inserted.

前記構成の自転車用車輪１によれば、モンキーあるいはスパナなどの工具によって、たとえば６組のボルト・ナットからなる第１締結部材９の締結を図３に示すように緩めることにより、リム４の軸方向寸法ｗ２と連結部材７の軸方向寸法ｗ２´を図１に示すリム４の軸方向寸法ｗ１と連結部材７の軸方向寸法ｗ１´よりも拡大できる。また、第１締結部材９の締結を解除して、第１締結部材９を除去することで、リム４と連結部材７を軸方向に分離できるので、タイヤ２の脱着を簡単に行うことができる。すなわち、タイヤ２の耳部２ａ，２ｂとリム４の耳部４ａ，４ｂとの係合解除およびリム４の耳部４ａ，４ｂに対するタイヤ２の耳部２ａ，２ｂの係合を、従来のように専用のヘラ状の金属製工具を使用することなく、指先による単純な作業によって簡単に行うことができ、タイヤ２に内蔵されているチューブ３の脱着も簡単に行うことができる。 According to the bicycle wheel 1 configured as described above, the shaft of the rim 4 is loosened by loosening the fastening of the first fastening member 9 made up of, for example, six sets of bolts and nuts with a tool such as a monkey or a spanner as shown in FIG. The direction dimension w2 and the axial direction dimension w2 ′ of the connecting member 7 can be made larger than the axial direction dimension w1 of the rim 4 and the axial direction dimension w1 ′ of the connecting member 7 shown in FIG. Moreover, since the rim | limb 4 and the connection member 7 can be isolate | separated to an axial direction by canceling | releasing the fastening of the 1st fastening member 9 and removing the 1st fastening member 9, the removal | desorption of the tire 2 can be performed easily. . In other words, the engagement between the ears 2a, 2b of the tire 2 and the ears 4a, 4b of the rim 4 and the engagement of the ears 2a, 2b of the tire 2 with the ears 4a, 4b of the rim 4 are the same as in the prior art. In addition, without using a dedicated spatula-shaped metal tool, it can be easily performed by a simple operation with a fingertip, and the tube 3 incorporated in the tire 2 can be easily attached and detached.

したがって、タイヤ２を交換したい場合やパンクを確認した場合などにおいて、その都度修理業者に委ねることなく自転車所有者サイドの素人でも簡単にタイヤ２およびチューブ３を脱着できる。また、修理店での熟練した作業者によるタイヤ２の脱着がより一層簡単になり、いずれの場合でも、従来必要とされていた専用のヘラ状の金属製工具が不要で、モンキーやスパナなどの使用頻度の高い一般的な工具によって簡単に脱着作業を実行できる。 Therefore, when it is desired to replace the tire 2 or when a puncture is confirmed, the tire 2 and the tube 3 can be easily attached and detached even by an amateur on the bicycle owner's side without entrusting the repairer each time. In addition, the tire 2 can be easily attached and detached by skilled workers at a repair shop, and in any case, a special spatula-shaped metal tool that has been required in the past is unnecessary, such as a monkey or a spanner. The detachment work can be easily performed with a general tool that is frequently used.

前記実施形態では、リム４とハブ６とをディスク状の連結部材７により一体に結合した構成の自転車用車輪１で説明しているが、図４に示すように、連結部材７を複数本（たとえば７本）のアーム部７Ａによって構成してもよい。これによると、所定の強度を確保した上で自転車用車輪１の軽量化を図るとともに、使用材料を節減できる。なお、図４において、前記図１〜図３と同一部分には、同一符号を付して重複する説明は省略する。 In the above-described embodiment, the bicycle wheel 1 having the structure in which the rim 4 and the hub 6 are integrally coupled by the disk-shaped coupling member 7 is described. However, as shown in FIG. For example, it may be configured by seven arm portions 7A. According to this, while ensuring the predetermined intensity | strength, while aiming at weight reduction of the wheel 1 for bicycles, material to be used can be saved.
