Description

本発明は、磁石などの検出対象体を車輪のスポークに取り付ける検出対象体の取付装置、およびこの取付装置を備えた自転車に関するものである。   The present invention relates to an attachment device for an object to be detected for attaching an object to be detected such as a magnet to a spoke of a wheel, and a bicycle including the attachment device.

自転車の走行速度や走行距離などを検出するために、自転車にスピードメータを取り付けることがある。この場合、自転車の車輪のスポークに、取付装置を用いて磁石を取り付けており、また、車体（前フォークなど）における、前記磁石が１回転ごとに接近する箇所に、磁石によりＯＮ・ＯＦＦするリードスイッチなどの検出装置を配設している。そして、自転車の走行に伴って車輪が回転して磁石がリードスイッチに接近した際に、リードスイッチがＯＦＦ状態からＯＮ状態に切り換わるので、このリードスイッチのＯＮ・ＯＦＦ信号に基づいて、自転車の走行速度や走行距離などをスピードメータで表示するよう構成されている。   A speedometer may be attached to the bicycle in order to detect the traveling speed or traveling distance of the bicycle. In this case, a magnet is attached to the spokes of the bicycle wheel using an attachment device, and a lead that is turned ON / OFF by the magnet at a position on the vehicle body (such as a front fork) that approaches the magnet every rotation. A detection device such as a switch is provided. When the wheel rotates as the bicycle travels and the magnet approaches the reed switch, the reed switch switches from the OFF state to the ON state. Therefore, based on the ON / OFF signal of the reed switch, The travel speed and travel distance are displayed on a speedometer.

磁石を車輪のスポークに取り付ける取付装置は、例えば、特許文献１およびこれに対応する欧州特許である特許文献２などに開示されている。
図１８、図１９に示すように、この取付装置５０は、検出対象体としての磁石５７を内部に収容する太径筒状の磁石収容部５１を有する磁石収容部材５３と、連結部材としての止めねじ５４と、リング５５とから構成されている。磁石収容部材５３には、内部（軸心部）にねじ部５２ａが形成された細径筒状の突出片５２を有し、この磁石収容部材５３のねじ部５２ａに止めねじ５４がねじ込まれる。また、突出片５２の外周にリング５５が配設され、突出片５２には、雌ねじ部５２ａを直径方向に２分するような割り溝部５２ｂも形成されている。 An attachment device for attaching a magnet to a spoke of a wheel is disclosed in, for example, Patent Literature 1 and Patent Literature 2 which is a European patent corresponding thereto.
As shown in FIGS. 18 and 19, the attachment device 50 includes a magnet housing member 53 having a large-diameter cylindrical magnet housing portion 51 that houses a magnet 57 as a detection target body, and a stopper as a connecting member. It consists of a screw 54 and a ring 55. The magnet housing member 53 has a small-diameter cylindrical protruding piece 52 in which a screw portion 52 a is formed inside (axial center portion), and a set screw 54 is screwed into the screw portion 52 a of the magnet housing member 53. Further, a ring 55 is disposed on the outer periphery of the protruding piece 52, and the protruding piece 52 is also formed with a split groove portion 52b that divides the female screw portion 52a into two in the diameter direction.

そして、この取付装置５０を取り付ける際には、割り溝部５２ｂの奥部までスポーク５６が通されて、スポーク５６の一部が、磁石収容部５１における突出片５２が設けられている円形面（磁石収容部５１の背面）５１ａに接するように配置される。この後、リング５５を突出片５２の外周に嵌め込み、止めねじ５４の軸部５４ａを突出片５２のねじ部５２ａにねじ込む。これにより、止めねじ５４の頭部５４ｂによりリング５５をスポーク５６側に押し込んで、リング５５の端面と磁石収容部材５３の円形面５１ａとによりスポーク５６を挟持した状態で固定している。   And when attaching this attachment apparatus 50, the spoke 56 is passed to the innermost part of the split groove part 52b, and a part of the spoke 56 is a circular surface (magnet provided with the protruding piece 52 in the magnet accommodating part 51). It is arranged so as to be in contact with the rear surface 51a of the accommodating portion 51. Thereafter, the ring 55 is fitted on the outer periphery of the protruding piece 52, and the shaft portion 54 a of the set screw 54 is screwed into the screw portion 52 a of the protruding piece 52. Thereby, the ring 55 is pushed into the spoke 56 side by the head 54 b of the set screw 54, and the spoke 56 is fixed in a state of being sandwiched between the end surface of the ring 55 and the circular surface 51 a of the magnet housing member 53.

なお、この引用文献１、２における実施例には、突出片５２のねじ部（雌ねじ部）５２ａが平行ねじであり、止めねじ５４を突出片５２のねじ部５２ａにねじ込んだ際に、突出片５２が割り溝部５２ｂを中心として開き気味に変形しようとすることが記載されている。そして、突出片５２の外周にはリング５５が配設されているため、突出片５２はリング５５により開くことが規制された状態でリング５５に圧接するよう構成されている。   In the examples in the cited documents 1 and 2, the threaded portion (female threaded portion) 52a of the projecting piece 52 is a parallel thread, and when the set screw 54 is screwed into the threaded portion 52a of the projecting piece 52, the projecting piece It is described that 52 tends to open and deform about the split groove 52b. And since the ring 55 is arrange | positioned in the outer periphery of the protrusion piece 52, the protrusion piece 52 is comprised so that the ring 55 may be press-contacted in the state by which the opening was controlled by the ring 55.

この取付装置５０によれば、比較的、簡単かつコンパクトな構造でありながら、磁石５７をスポーク５６に良好に取り付けることができる。   According to this attachment device 50, the magnet 57 can be attached to the spoke 56 satisfactorily while having a relatively simple and compact structure.

しかしながら、図１８、図１９に示した従来の取付装置５０は、突出片５２を磁石収容部５１と一体に形成した場合でも、構成する部品として、磁石収容部材５３と、連結部材としての止めねじ５４と、リング５５との３つの部品が必要であるため、その分だけ製造コストが増加したり、取付装置５０を取り付ける際に手間や時間が多めに必要となったりする課題があった。   However, in the conventional mounting device 50 shown in FIGS. 18 and 19, even when the protruding piece 52 is formed integrally with the magnet housing portion 51, the magnet housing member 53 and the set screw as the connecting member are included as components. Since the three parts 54 and the ring 55 are necessary, there are problems that the manufacturing cost is increased by that amount, and that much labor and time are required when attaching the attachment device 50.

本発明は上記課題を解決するもので、簡単かつコンパクトな構造であると同時に、少ない部品点数で構成できる取付装置を提供することを目的とするものである。   SUMMARY OF THE INVENTION The present invention solves the above-described problems, and an object of the present invention is to provide an attachment device that can be configured with a small number of parts while having a simple and compact structure.

上記課題を解決するために、本発明は、検出装置で検出される検出対象体を車輪のスポークに取り付ける検出対象体の取付装置であって、前記検出対象体を収容する収容部材と、この収容部材に連結される連結部材とを備え、前記収容部材は、検出対象体を収容する収容部と、この収容部に続いて形成された筒状部と、この筒状部の径方向に形成されてスポークが挿通される割り溝部と、前記筒状部の軸心方向に延びるように形成されて前記割り溝部に連通する雌ねじ部と、を有し、前記連結部材は、前記筒状部の雌ねじ部にねじこまれるねじ軸部と、ねじ軸部に続くねじ頭部と、ねじ頭部に連続して一体形成されて前記筒状部に外嵌されるリング部と、を有することを特徴とする。   In order to solve the above-described problems, the present invention provides a detection target body mounting device for mounting a detection target body detected by a detection device to a spoke of a wheel, the storage member storing the detection target body, and the storage A connecting member that is connected to the member, and the storage member is formed in a storage portion that stores the detection target body, a cylindrical portion that is formed following the storage portion, and a radial direction of the cylindrical portion. A split groove portion through which the spoke is inserted, and a female screw portion formed so as to extend in the axial direction of the cylindrical portion and communicated with the split groove portion, and the connecting member is a female screw of the cylindrical portion A screw shaft portion that is screwed into the portion; a screw head that follows the screw shaft portion; and a ring portion that is continuously formed integrally with the screw head and is fitted onto the tubular portion. To do.

この構成において、当該取付装置を介して検出対象体を車輪のスポークに取り付ける際には、検出対象体を収容した収容部材の割り溝部にスポークが通るように収容部材を組み付け、この後、連結部材のねじ軸部を収容部材の筒状部の雌ねじ部にねじ込む。これにより、ねじ頭部に連続して一体形成されたリング部をスポーク側に移動させて筒状部に外嵌させながら、収容部材の割り溝部の壁面と連結部材のねじ軸部の先端（または連結部材のリング部）との間でスポークを挟持できて、取付装置をスポークに固定することができる。   In this configuration, when the detection target body is attached to the spokes of the wheel via the attachment device, the housing member is assembled so that the spoke passes through the split groove portion of the housing member that houses the detection target body, and then the connecting member. The screw shaft portion is screwed into the female screw portion of the cylindrical portion of the housing member. As a result, the ring part formed integrally with the screw head is moved to the spoke side and fitted to the cylindrical part, and the wall surface of the split groove part of the housing member and the tip of the screw shaft part of the connecting member (or The spoke can be held between the ring portion of the connecting member and the attachment device can be fixed to the spoke.

この構成によれば、連結部材にリング部が一体形成されて、当該取付装置を、収容部材と連結部材との２つの部品で構成できるので、その分だけ製造コストを抑えたり、当該取付装置を取り付ける際の手間や時間を省いたりすることができて作業能率も向上する。   According to this configuration, since the ring portion is integrally formed on the connecting member, the mounting device can be configured with two parts, that is, the housing member and the connecting member. This saves labor and time during installation and improves work efficiency.

また、本発明は、連結部材のねじ軸部を収容部材の筒状部にねじ込んだ際に、収容部材の筒状部が割り溝部を中心として開くように変形して、収容部材の筒状部が連結部材のリング部に密接するよう構成されていることを特徴とする。   Further, the present invention is such that when the screw shaft portion of the connecting member is screwed into the tubular portion of the housing member, the tubular portion of the housing member is deformed so as to open around the split groove portion, Is configured to be in close contact with the ring portion of the connecting member.

この構成によれば、連結部材のねじ軸部を収容部材の筒状部の雌ねじ部にねじ込むと、収容部材の筒状部が連結部材のリング部に密接する。これにより、連結部材のねじ軸部が収容部材の筒状部の雌ねじ部から抜け出す方向（ねじ軸部が緩む方向）に回転しようとしても、この回転がリング部を介して収容部材の筒状部で阻止される。   According to this configuration, when the screw shaft portion of the connecting member is screwed into the female screw portion of the cylindrical portion of the housing member, the cylindrical portion of the housing member comes into close contact with the ring portion of the connecting member. As a result, even if the screw shaft portion of the connecting member tries to rotate in a direction in which the screw shaft portion is pulled out from the female screw portion of the cylindrical portion of the housing member (a direction in which the screw shaft portion is loosened), this rotation is performed via the ring portion. Is blocked.

また、本発明は、連結部材のねじ軸部がスポークに当接可能に構成され、連結部材のねじ軸部を収容部材の筒状部にねじ込んでスポークに当接させることにより、収容部材の筒状部が割り溝部を中心として開くように変形して、収容部材の筒状部が連結部材のリング部に密接するよう構成されていることを特徴とする。   Further, the present invention is configured so that the screw shaft portion of the connecting member can be brought into contact with the spoke, and the screw shaft portion of the connecting member is screwed into the cylindrical portion of the containing member and brought into contact with the spoke, thereby allowing the tube of the containing member to The cylindrical portion of the housing member is deformed so as to open about the split groove portion, and the cylindrical portion of the housing member is in close contact with the ring portion of the connecting member.

この構成によれば、連結部材のねじ軸部を収容部材の筒状部にねじ込む際、連結部材のねじ軸部がスポークに当接するまでは、収容部材の筒状部は変形しないので、連結部材のねじ軸部を収容部材の筒状部に、比較的容易に、すなわち良好な作業性を有する状態で、ねじ込むことができる。一方、連結部材のねじ軸部を収容部材の筒状部にねじ込んでスポークに当接させると、連結部材のねじ軸部と収容部材の割り溝部の壁面との間で、スポークを挟持できて、取付装置をスポークに固定することができる。この際に、収容部材の筒状部が割り溝部を中心として開くように変形して、収容部材の筒状部が連結部材のリング部に密接するので、連結部材のねじ軸部が収容部材の筒状部の雌ねじ部から抜け出す方向に回転し難くなり、連結部材が緩み方向に回転することが阻止される。   According to this configuration, when the screw shaft portion of the connecting member is screwed into the cylindrical portion of the housing member, the tubular portion of the housing member is not deformed until the screw shaft portion of the connecting member comes into contact with the spoke. The screw shaft portion can be screwed into the cylindrical portion of the housing member relatively easily, that is, with good workability. On the other hand, when the screw shaft portion of the connecting member is screwed into the cylindrical portion of the housing member and brought into contact with the spoke, the spoke can be sandwiched between the screw shaft portion of the connecting member and the wall surface of the split groove portion of the housing member, The attachment device can be fixed to the spoke. At this time, the tubular portion of the housing member is deformed so as to open around the split groove portion, and the tubular portion of the housing member is in close contact with the ring portion of the connecting member. It becomes difficult to rotate in the direction of coming out of the female thread portion of the cylindrical portion, and the connecting member is prevented from rotating in the loosening direction.

また、本発明は、検出装置で検出される検出対象体を車輪のスポークに取り付ける検出対象体の取付装置であって、前記検出対象体を収容する収容部材と、この収容部材に連結される連結部材とを備え、前記収容部材は、検出対象体を収容する収容部と、この収容部に続いて形成された筒状部と、この筒状部の径方向に形成されてスポークが挿通される割り溝部と、前記筒状部の外周に形成された雄ねじ部と、を有し、前記連結部材は、前記筒状部の雄ねじ部に螺合される雌ねじ部が内周に形成されたナット形状体で構成されている
ことを特徴とする。 Moreover, this invention is an attachment apparatus of the detection target body which attaches the detection target body detected by a detection apparatus to the spoke of a wheel, Comprising: The accommodation member which accommodates the said detection target body, and the connection connected with this accommodation member And a housing part that houses the object to be detected, a tubular part that is formed following the housing part, and a spoke that is inserted in the radial direction of the tubular part. A split groove portion and a male screw portion formed on the outer periphery of the cylindrical portion, and the connecting member is a nut shape in which a female screw portion screwed into the male screw portion of the cylindrical portion is formed on the inner periphery It is composed of a body.

この構成において、当該取付装置を介して検出対象体を車輪のスポークに取り付ける際には、検出対象体を収容した収容部材の割り溝部にスポークが通るように収容部材を組み付け、この後、収容部材の筒状部の雄ねじ部に、ナット形状体で構成されている連結部材をねじ込む。これにより、前記筒状部の雄ねじ部に連結部材の雌ねじ部がねじ込まれて、ナット形状体で構成されている連結部材がスポークに当接して押し付けられ、連結部材と収容部材の収容部との間にスポークを挟持した状態で取付装置を固定することができる。   In this configuration, when the detection target body is attached to the spokes of the wheel via the attachment device, the storage member is assembled so that the spoke passes through the split groove portion of the storage member that stores the detection target body. A connecting member formed of a nut-shaped body is screwed into the male thread portion of the cylindrical portion. As a result, the female threaded portion of the connecting member is screwed into the male threaded portion of the cylindrical portion, and the connecting member formed of the nut-shaped body is pressed against the spoke, and the connecting member and the accommodating portion of the accommodating member are The attachment device can be fixed with the spoke sandwiched therebetween.

この構成によれば、当該取付装置を、収容部材と、ナット形状体で構成されている連結部材との２つの部品で構成できるので、その分だけ製造コストを抑えたり、当該取付装置を取り付ける際の手間や時間を省いたりすることができて作業能率も向上する。   According to this configuration, since the mounting device can be configured with two parts, that is, a housing member and a connecting member formed of a nut-shaped body, when the manufacturing cost is reduced or the mounting device is mounted. This saves time and effort and improves work efficiency.

また、本発明の自転車は、前記した検出対象体の取付装置が車輪のスポークに取り付けられた自転車であって、前記取付装置に設けられた検出対象体を検出する検出装置が固定部材に取り付けられていることを特徴とする。   Further, the bicycle of the present invention is a bicycle in which the above-described attachment device for the detection object is attached to the spokes of the wheel, and the detection device for detecting the detection object provided in the attachment device is attached to the fixing member. It is characterized by.

本発明によれば、検出対象体を収容する収容部材と、収容部材に連結される連結部材とを備え、連結部材に、筒状部に外嵌されるリング部を一体形成することにより、当該取付装置を、収容部材と連結部材との２つの部品で構成できるので、その分だけ製造コストを抑えたり、当該取付装置を取り付ける際の手間や時間を省いたりすることができて作業能率も向上する。   According to the present invention, it is possible to provide an accommodation member that accommodates the detection target body and a connection member that is coupled to the accommodation member, and by integrally forming a ring portion that is externally fitted to the tubular portion on the connection member, Since the mounting device can be composed of two parts, a housing member and a connecting member, the manufacturing cost can be reduced by that much, and the labor and time for mounting the mounting device can be saved, improving work efficiency. To do.

また、連結部材のねじ軸部を収容部材の筒状部にねじ込んだ際に、収容部材の筒状部が割り溝部を中心として開くように変形して、収容部材の筒状部が連結部材のリング部に密接するよう構成することにより、連結部材のねじ軸部が収容部材の筒状部の雌ねじ部から抜け出す方向（ねじ軸部が緩む方向）に回転しようとしても、この回転がリング部を介して収容部材の筒状部で阻止される。これにより、ねじ軸部が緩んで、磁石を組み付けた取付装置がスポークに沿って車輪の半径方向に移動して、自転車の走行速度や走行距離などを検出できなくなってしまうような不具合の発生を防止できて、信頼性を向上させることができる。   Further, when the screw shaft portion of the connecting member is screwed into the tubular portion of the housing member, the tubular portion of the housing member is deformed so as to open around the split groove portion, and the tubular portion of the housing member is By configuring so as to be in close contact with the ring portion, even if the screw shaft portion of the connecting member tries to rotate in a direction in which the screw shaft portion is pulled out from the female screw portion of the cylindrical portion of the housing member (direction in which the screw shaft portion is loosened), this rotation causes the ring portion to rotate. And is blocked by the cylindrical portion of the housing member. As a result, the screw shaft part is loosened, and the mounting device with the magnet assembled moves in the radial direction of the wheel along the spokes, and it becomes impossible to detect the traveling speed or traveling distance of the bicycle. This can be prevented and the reliability can be improved.

また、連結部材のねじ軸部をスポークに当接可能に構成し、連結部材のねじ軸部を収容部材の筒状部にねじ込んでスポークに当接させることで、収容部材の筒状部が連結部材のリング部に密接するよう構成することにより、連結部材のねじ軸部がスポークに当接するまでは、収容部材の筒状部は変形しないので、連結部材のねじ軸部を収容部材の筒状部に比較的容易にねじ込むことができる。   In addition, the threaded shaft portion of the connecting member is configured to be able to contact the spoke, and the threaded shaft portion of the connecting member is screwed into the tubular portion of the housing member and brought into contact with the spoke, thereby connecting the tubular portion of the housing member. Since the cylindrical portion of the housing member is not deformed until the screw shaft portion of the connecting member comes into contact with the spoke, the screw shaft portion of the connecting member is formed into the cylindrical shape of the housing member. It can be screwed into the part relatively easily.

また、検出対象体を収容する収容部材と、収容部材に連結される連結部材とを備え、前記収容部材に、検出対象体を収容する収容部と、この収容部に続いて形成された筒状部と、この筒状部の径方向に形成されてスポークが挿通される割り溝部と、前記筒状部の外周に形成された雄ねじ部と、を有し、前記連結部材は、前記筒状部の雄ねじ部に螺合される雌ねじ部が内周に形成されたナット形状体で構成することによっても、当該取付装置を、スポークに良好に取り付けることができるとともに、当該取付装置を、収容部材と、ナット形状体で構成されている連結部材との２つの部品で構成できるので、その分だけ製造コストを抑えたり、当該取付装置を取り付ける際の手間や時間を省いたりすることができて作業能率も向上する。   Moreover, it is equipped with the accommodating member which accommodates a detection target body, and the connection member connected with a accommodation member, The accommodating part which accommodates a detection target body in the said accommodation member, The cylindrical shape formed following this accommodating part Part, a split groove part formed in the radial direction of the cylindrical part and through which the spoke is inserted, and a male screw part formed on the outer periphery of the cylindrical part, and the connecting member is the cylindrical part The mounting device can be satisfactorily attached to the spoke, and the mounting device can be attached to the housing member by configuring the female screw portion screwed to the male screw portion with a nut-shaped body formed on the inner periphery. Since it can be composed of two parts with a connecting member composed of a nut-shaped body, the production cost can be reduced by that much, and labor and time when mounting the mounting device can be saved, and work efficiency Will also improve.

図１において、１は自転車であり、フレーム２と前車輪３と後車輪４とハンドル５とサドル６とペダル７等を有している。フレーム２は前フォーク８と上パイプ９と下パイプ１０と立パイプ１１とバックフォーク１２とチェーンステー１３（固定部材の一例）となどを有している。   In FIG. 1, reference numeral 1 denotes a bicycle, which has a frame 2, a front wheel 3, a rear wheel 4, a handle 5, a saddle 6, a pedal 7, and the like. The frame 2 includes a front fork 8, an upper pipe 9, a lower pipe 10, a standing pipe 11, a back fork 12, a chain stay 13 (an example of a fixing member), and the like.

チェーンステー１３には、後車輪４の回転を検出し、この検出値に基いて走行速度を求める速度検出装置１６（検出装置の一例）が設けられている。また、ハンドル５には、検出された走行速度を表示する表示装置１７が設けられている。速度検出装置１６は円形の磁石１９（検出対象体の一例）の磁気を検出するものであり、磁石１９は取付装置２０によって後車輪４のスポーク１４に取り付けられている。なお、スポーク１４は円形の断面形状を有している。これらの速度検出装置１６、表示装置１７および磁石１９などによりいわゆるスピードメータが構成されている。すなわち、自転車１で走行している際、後車輪４が一回転する毎に、速度検出装置１６が磁石１９の磁気を検出して信号を発信し、この信号に基いて自転車１の走行速度が求められ、この走行速度が表示装置１７に表示されるよう構成されている。   The chain stay 13 is provided with a speed detection device 16 (an example of a detection device) that detects the rotation of the rear wheel 4 and obtains the traveling speed based on the detected value. The handle 5 is provided with a display device 17 for displaying the detected traveling speed. The speed detection device 16 detects the magnetism of a circular magnet 19 (an example of a detection target), and the magnet 19 is attached to the spoke 14 of the rear wheel 4 by an attachment device 20. The spoke 14 has a circular cross-sectional shape. These speed detector 16, display device 17, magnet 19, etc. constitute a so-called speedometer. That is, when the bicycle 1 is running, each time the rear wheel 4 makes one revolution, the speed detection device 16 detects the magnetism of the magnet 19 and sends a signal. Based on this signal, the running speed of the bicycle 1 is determined. The travel speed is obtained and displayed on the display device 17.

図２〜図８に示すように、検出対象体としての磁石１９をスポーク１４に取り付ける第１の実施の形態に係る検出対象体の取付装置２０は、磁石１９を収容する収容部材２１と、収容部材２１に連結される連結部材２６とから構成されている。   As shown in FIGS. 2 to 8, the attachment device 20 for the detection object according to the first embodiment for attaching the magnet 19 as the detection object to the spoke 14 includes an accommodation member 21 for accommodating the magnet 19, and accommodation. The connecting member 26 is connected to the member 21.

収容部材２１は、検出対象体としての磁石１９を収容する収容部２２と、この収容部２２に続いて形成された筒状部２４と、この筒状部２４の径方向に形成されてスポーク１４が挿通される割り溝部２３と、筒状部２４の軸心方向に延びて割り溝部２３に連通する雌ねじ部２５と、を有している。収容部材２１は例えば金属製または樹脂製とされて、磁石１９を収容する収容部２２と、割り溝部２３や雌ねじ部２５が形成された筒状部２４とが、一体形成されている。   The accommodating member 21 includes an accommodating portion 22 that accommodates the magnet 19 as a detection target body, a cylindrical portion 24 that is formed following the accommodating portion 22, and a spoke 14 that is formed in the radial direction of the cylindrical portion 24. And a female thread portion 25 that extends in the axial direction of the cylindrical portion 24 and communicates with the split groove portion 23. The accommodating member 21 is made of, for example, metal or resin, and an accommodating portion 22 that accommodates the magnet 19 and a cylindrical portion 24 in which the split groove portion 23 and the female screw portion 25 are formed are integrally formed.

なお、この実施の形態では、収容部２２と筒状部２４とが同軸心（詳しくは、スポーク１４に直交する方向を軸心方向として同軸心）で段付きの円柱形状とされている。また、左側のチェーンステー１３に取り付けられている速度検出装置１６に臨むように、取付装置２０における左側に収容部２２が設けられ、この収容部２２から右側に延びるように筒状部２４が形成されている。そして、収容部２２において、左側に開口するように収容凹部２２ａが形成され（図８参照）、この収容凹部２２ａに円形（円盤状）の磁石１９が収容されて固着されている。また、図４、図８などに示すように、割り溝部２３は、筒状部２４を右側の開口部から左側に延びて、筒状部２４を径方向（直径方向）に２分割するように形成され、雌ねじ部２５は、割り溝部２３の中央部および筒状部２４の軸心部を通るように形成されている。筒状部２４にも段付き部２４ａが形成され、収容部２２から右側に続く太径筒状部２４ｂに、段付き部２４ａを介して、太径筒状部２４ｂよりも細径の細径筒状部２４ｃが右側に続いて形成されている。そして、割り溝部２３は、太径筒状部２４ｂの途中箇所から細径筒状部２４ｃを通って細径筒状部２４ｃの右端面に開口し、この開口部を通して、割り溝部２３の奥部（割り溝部２３の左端部）にスポーク１４が通される。   In this embodiment, the accommodating portion 22 and the cylindrical portion 24 are formed in a stepped columnar shape with a coaxial center (specifically, a coaxial center with the direction orthogonal to the spoke 14 as the axial direction). Further, a housing portion 22 is provided on the left side of the mounting device 20 so as to face the speed detection device 16 attached to the left chain stay 13, and a cylindrical portion 24 is formed so as to extend to the right side from the housing portion 22. Has been. And in the accommodating part 22, the accommodating recessed part 22a is formed so that it may open on the left side (refer FIG. 8), and the circular (disk shape) magnet 19 is accommodated and fixed to this accommodating recessed part 22a. Also, as shown in FIGS. 4 and 8, the split groove portion 23 extends the cylindrical portion 24 from the right opening to the left side, and divides the cylindrical portion 24 into two in the radial direction (diameter direction). The female screw portion 25 is formed so as to pass through the center portion of the split groove portion 23 and the axial center portion of the cylindrical portion 24. A stepped portion 24a is also formed in the tubular portion 24, and a large diameter tubular portion 24b that continues from the housing portion 22 on the right side is narrower than the large diameter tubular portion 24b via the stepped portion 24a. A cylindrical portion 24c is formed following the right side. And the split groove part 23 opens to the right end surface of the small diameter cylindrical part 24c through the small diameter cylindrical part 24c from the middle part of the large diameter cylindrical part 24b, and the inner part of the split groove part 23 passes through this opening part. The spoke 14 is passed through (the left end portion of the split groove portion 23).

また、図２〜図８に示すように、連結部材２６は、筒状部２４の雌ねじ部２５にねじこまれるねじ軸部２７と、ねじ軸部２７に続くねじ頭部２８と、筒状部２４に外嵌されるリング部２９と、を有する。連結部材２６は例えば金属製または樹脂製とされて、ねじ軸部２７とねじ頭部２８とリング部２９とが連続して一体形成されている。なお、この実施の形態では、連結部材２６のねじ頭部２８と筒状部２４の雌ねじ部２５とは互いに対応した直径（同様な直径で、ねじ込み用の隙間分だけ異なる）で平行直線状（またはテーパ状であってもよい）のねじとされている。また、この実施の形態では、図８に示すように、ねじ頭部２８からのねじ軸部２７の突出寸法が、ねじ頭部２８からのリング部２９の突出寸法よりも大きくされて、図７に示すように、連結部材２６のねじ軸部２７を収容部材２１の雌ねじ部２５に奥までねじ込んだ際に、連結部材２６のねじ軸部２７の先端がスポーク１４に当接可能に構成されている。   As shown in FIGS. 2 to 8, the connecting member 26 includes a screw shaft portion 27 screwed into the female screw portion 25 of the tubular portion 24, a screw head portion 28 following the screw shaft portion 27, and the tubular portion. 24, and a ring portion 29 that is externally fitted to 24. The connecting member 26 is made of, for example, metal or resin, and a screw shaft portion 27, a screw head portion 28, and a ring portion 29 are integrally formed continuously. In this embodiment, the screw head portion 28 of the connecting member 26 and the female screw portion 25 of the cylindrical portion 24 are parallel straight lines with similar diameters (similar diameters, differing by a gap for screwing) ( Or may be tapered). Further, in this embodiment, as shown in FIG. 8, the projecting dimension of the screw shaft portion 27 from the screw head 28 is made larger than the projecting dimension of the ring portion 29 from the screw head 28, and FIG. As shown in FIG. 4, when the screw shaft portion 27 of the connecting member 26 is screwed into the female screw portion 25 of the housing member 21 as far as it will go, the tip of the screw shaft portion 27 of the connecting member 26 can be brought into contact with the spoke 14. Yes.

この構成における、当該取付装置２０を介して検出対象体としての磁石１９を後車輪４のスポーク１４に取り付ける手順は以下の通りである。
図３、図４などに示すように、まず、磁石１９を収容した収容部材２１の割り溝部２３の奥部にスポーク１４が通るように、収容部材２１をスポーク１４に組み付ける。この後、連結部材２６のねじ軸部２７を収容部材２１の筒状部２４の雌ねじ部２５にねじ込む。これにより、連結部材２６がスポーク１４側に移動し、連結部材２６におけるねじ頭部２７に連続して一体形成されたリング部２９が細径筒状部２４ｃに外嵌する。また、ねじ軸部２７が奥側までねじ込まれるように連結部材２６を回転させることで、連結部材２６のねじ軸部２７の先端がスポーク１４に当接する。この結果、収容部材２１の割り溝部２３の底部と連結部材２６のねじ軸部２７の先端部とによりスポーク１４が挟持され、これにより取付装置２０がスポーク１４に固定される。 In this configuration, the procedure for attaching the magnet 19 as the detection object to the spoke 14 of the rear wheel 4 through the attachment device 20 is as follows.
As shown in FIGS. 3, 4, etc., first, the housing member 21 is assembled to the spoke 14 so that the spoke 14 passes through the inner part of the split groove portion 23 of the housing member 21 that houses the magnet 19. Thereafter, the screw shaft portion 27 of the connecting member 26 is screwed into the female screw portion 25 of the cylindrical portion 24 of the housing member 21. As a result, the connecting member 26 moves to the spoke 14 side, and the ring portion 29 that is integrally formed continuously with the screw head 27 in the connecting member 26 is externally fitted to the small-diameter cylindrical portion 24c. Further, by rotating the connecting member 26 so that the screw shaft portion 27 is screwed to the back side, the tip end of the screw shaft portion 27 of the connecting member 26 comes into contact with the spoke 14. As a result, the spoke 14 is sandwiched between the bottom of the split groove 23 of the housing member 21 and the tip of the screw shaft portion 27 of the connecting member 26, whereby the attachment device 20 is fixed to the spoke 14.

また、この際に、連結部材２６のねじ軸部２７の先端がスポーク１４に軽く当接した状態から、連結部材２６をさらにスポーク１４に強く当接するように回転させると、連結部材２６のねじ軸部２７におけるねじの山部が、収容部材２１の雌ねじ部２５の山部に乗り上げるように摺接するため、連結部材２６の筒状部２４が割り溝部２３を中心として開くように変形して、収容部材２１の細径筒状部２４ｃの外周が収容部材２１のリング部２９の内周に密接する。この結果、連結部材２６のねじ軸部２７が収容部材２１の筒状部２４の雌ねじ部２５から抜け出す方向に連結部材２６が回転し難くなり、連結部材２６が緩むことが阻止される。これにより、一旦連結部材２６を締め付けると、ねじ軸部２７が緩んで磁石１９を組み付けた取付装置がスポーク１４に沿って後車輪４の半径方向に移動して自転車１の走行速度や走行距離などを検出できなくなることを防止できて、信頼性を向上させることができる。   At this time, if the connecting member 26 is further rotated so as to be in strong contact with the spoke 14 from the state where the tip of the screw shaft portion 27 of the connecting member 26 is in light contact with the spoke 14, the screw shaft of the connecting member 26. Since the thread crest in the portion 27 is in sliding contact with the crest of the female thread portion 25 of the housing member 21, the cylindrical portion 24 of the connecting member 26 is deformed so as to open around the split groove 23 and accommodated. The outer periphery of the thin cylindrical portion 24 c of the member 21 is in close contact with the inner periphery of the ring portion 29 of the housing member 21. As a result, it is difficult for the connecting member 26 to rotate in the direction in which the screw shaft portion 27 of the connecting member 26 comes out of the female screw portion 25 of the cylindrical portion 24 of the housing member 21, and the connecting member 26 is prevented from loosening. As a result, once the connecting member 26 is tightened, the attachment device with the screw shaft portion 27 loosened and the magnet 19 assembled is moved along the spoke 14 in the radial direction of the rear wheel 4 so that the bicycle 1 travel speed, travel distance, etc. Can be prevented, and reliability can be improved.

また、収容部材２１の筒状部２４の雌ねじ部２５は、連結部材２６のねじ軸部２７に対応する形状とされているため、連結部材２６のねじ軸部２７を収容部材２１の雌ねじ部２５にねじ込む際に、連結部材２６のねじ軸部２７がスポーク１４に当接するまでは、連結部材２６の筒状部２４は殆ど変形しないよう構成されている。これにより、連結部材２６の締付時において、連結部材２６のねじ軸部２７がスポーク１４に当接するまでは、連結部材２６のねじ軸部２７を収容部材２１の雌ねじ部２５に、比較的軽い力で容易にねじ込むことができ、作業性が良好となる。   Further, since the female screw portion 25 of the cylindrical portion 24 of the housing member 21 has a shape corresponding to the screw shaft portion 27 of the connecting member 26, the screw shaft portion 27 of the connecting member 26 is replaced with the female screw portion 25 of the housing member 21. When screwed into the cylindrical member 24, the cylindrical portion 24 of the connecting member 26 is configured to hardly deform until the screw shaft portion 27 of the connecting member 26 contacts the spoke 14. As a result, when the connecting member 26 is tightened, the screw shaft portion 27 of the connecting member 26 is relatively lightly connected to the female screw portion 25 of the housing member 21 until the screw shaft portion 27 of the connecting member 26 contacts the spoke 14. It can be easily screwed in by force, and workability is improved.

また、上記構成によれば、連結部材２６にリング部２９が一体形成されて、当該取付装置２０を、収容部材２１と連結部材２６との２つの部品で構成できるので、簡単かつコンパクトな構造であるだけでなく、製造コストを抑えたり、当該取付装置２０を取り付ける際の手間や時間を省いたりすることができ、これによっても作業能率が向上する。   Further, according to the above configuration, the ring portion 29 is formed integrally with the connecting member 26, and the mounting device 20 can be configured with two parts, that is, the accommodation member 21 and the connecting member 26, so that the structure is simple and compact. In addition, the manufacturing cost can be reduced, and the labor and time for attaching the attachment device 20 can be saved, which also improves the work efficiency.

上記実施の形態では、連結部材２６のねじ軸部２７をねじ込んだ際に、連結部材２６のねじ軸部２７の先端がスポーク１４に当接し、収容部材２１の割り溝部２３の底部と連結部材２６のねじ軸部２７の先端部とによりスポーク１４を挟持して当該取付装置２０を固定するよう構成した場合を述べたが、これに限るものではない。   In the above embodiment, when the screw shaft portion 27 of the connecting member 26 is screwed in, the tip end of the screw shaft portion 27 of the connecting member 26 contacts the spoke 14, and the bottom portion of the split groove portion 23 of the housing member 21 and the connecting member 26. Although the case where the spoke 14 is sandwiched between the tip of the screw shaft portion 27 and the attachment device 20 is fixed is described, the present invention is not limited to this.

図９、図１０は第１の実施の形態に係る取付装置の変形例を示すもので、この実施の形態では、連結部材２６のねじ軸部２７を収容部材２１の筒状部２４の雌ねじ部２５にねじ込んだ際に、連結部材２６のリング部２９がスポーク１４に当接し、収容部材２１の割り溝部２３の底部（壁面部）と連結部材２６のリング部２９とによりスポーク１４を挟持して当該取付装置２０を固定するよう構成されている。なお、この実施の形態では、図１０に示すように、ねじ頭部２８からのリング部２９の突出寸法が、ねじ頭部２８からのねじ軸部２７の突出寸法よりも大きくされて、図９に示すように、連結部材２６のねじ軸部２７を収容部材２１の雌ねじ部２５に奥までねじ込んだ際に、連結部材２６のリング部２９がスポーク１４に当接可能に構成されている。   9 and 10 show a modification of the mounting device according to the first embodiment. In this embodiment, the screw shaft portion 27 of the connecting member 26 is replaced by the female screw portion of the cylindrical portion 24 of the housing member 21. FIG. 25, the ring portion 29 of the connecting member 26 contacts the spoke 14, and the spoke 14 is sandwiched between the bottom portion (wall surface portion) of the split groove portion 23 of the housing member 21 and the ring portion 29 of the connecting member 26. The attachment device 20 is configured to be fixed. In this embodiment, as shown in FIG. 10, the projecting dimension of the ring portion 29 from the screw head 28 is made larger than the projecting dimension of the screw shaft portion 27 from the screw head 28. As shown, the ring portion 29 of the connecting member 26 is configured to be able to contact the spoke 14 when the screw shaft portion 27 of the connecting member 26 is screwed into the female screw portion 25 of the housing member 21 to the back.

このような構成でも、収容部材２１の割り溝部２３の底部（壁面部）と連結部材２６のリング部２９とによりスポーク１４を挟持して当該取付装置２０を固定することができる。また、上記実施の形態と同様に、連結部材２６にリング部２９が一体形成されて、当該取付装置２０を、収容部材２１と連結部材２６との２つの部品で構成できるので、その分だけ製造コストを抑えたり、当該取付装置２０を取り付ける際の手間や時間を省いたりすることができて作業能率も向上する。   Even in such a configuration, the attachment device 20 can be fixed by sandwiching the spoke 14 between the bottom portion (wall surface portion) of the split groove portion 23 of the housing member 21 and the ring portion 29 of the connecting member 26. Further, similarly to the above embodiment, the ring portion 29 is integrally formed with the connecting member 26, and the mounting device 20 can be constituted by two parts of the accommodation member 21 and the connecting member 26. Costs can be reduced, and labor and time for attaching the attachment device 20 can be saved, and work efficiency is also improved.

また、この実施の形態において、収容部材２１の筒状部２４の雌ねじ部２５を平行溝形状にしたり、連結部材２６のねじ軸部２７の直径より僅かに小径のねじ形状にしたりして、連結部材２６のねじ軸部２７を収容部材２１の筒状部２４の雌ねじ部２５にねじ込んだ際に、連結部材２６の筒状部２４が割り溝部２３を中心として開く方向に変形するように構成してもよい。   Further, in this embodiment, the female screw portion 25 of the cylindrical portion 24 of the housing member 21 is formed in a parallel groove shape, or is formed in a screw shape slightly smaller than the diameter of the screw shaft portion 27 of the connecting member 26. When the screw shaft portion 27 of the member 26 is screwed into the female screw portion 25 of the cylindrical portion 24 of the accommodating member 21, the cylindrical portion 24 of the connecting member 26 is deformed in the opening direction around the split groove portion 23. May be.

この構成によれば、連結部材２６のねじ軸部２７を収容部材２１の筒状部２４の雌ねじ部２５にねじ込むことで、連結部材２６の筒状部２４が割り溝部２３を中心として開いて、連結部材２６のリング部２９に密接する。したがって、連結部材２６を回転させる際の力として比較的大きな力を必要とするものの、連結部材２６のリング部２９がスポーク１４に当接するまで連結部材２６を回転させると、ねじ軸部２７が緩む方向に連結部材２６が回転することを阻止できる。これにより、ねじ軸部２７が緩んで、磁石１９を組み付けた取付装置がスポークに沿って車輪の半径方向に移動して、自転車の走行速度や走行距離などを検出できなくなることを防止できて、信頼性を向上させることができる。   According to this configuration, by screwing the screw shaft portion 27 of the connecting member 26 into the female screw portion 25 of the cylindrical portion 24 of the housing member 21, the cylindrical portion 24 of the connecting member 26 opens around the split groove portion 23. The ring portion 29 of the connecting member 26 is in close contact. Therefore, although a relatively large force is required as the force for rotating the connecting member 26, when the connecting member 26 is rotated until the ring portion 29 of the connecting member 26 contacts the spoke 14, the screw shaft portion 27 is loosened. The connecting member 26 can be prevented from rotating in the direction. As a result, it is possible to prevent the screw shaft portion 27 from being loosened and the attachment device assembled with the magnet 19 from moving in the radial direction of the wheel along the spokes, so that the traveling speed or traveling distance of the bicycle cannot be detected. Reliability can be improved.

（第２の実施の形態）
次に、本発明の第２の実施の形態に係る検出対象体の取付装置３０について、図１１〜図１７を参照しながら説明する。 (Second Embodiment)
Next, a detection object mounting apparatus 30 according to a second embodiment of the present invention will be described with reference to FIGS.

図１１〜図１７に示すように、検出対象体としての磁石１９をスポーク１４に取り付ける取付装置３０は、磁石１９を収容する収容部材３１と、収容部材３１に連結される連結部材３６とから構成されている。   As shown in FIGS. 11 to 17, the attachment device 30 for attaching the magnet 19 as the detection target body to the spoke 14 includes a housing member 31 that houses the magnet 19 and a connecting member 36 that is coupled to the housing member 31. Has been.

収容部材３１は、検出対象体としての磁石１９を収容する収容部３２と、この収容部３２に続いて形成された筒状部３４と、この筒状部３４の径方向に形成されてスポーク１４が挿通される割り溝部３３と、筒状部３４の外周に形成された雄ねじ部３５と、を有している。収容部材３１は例えば金属製または樹脂製とされて、磁石１９を収容する収容部３２と、割り溝部３３や雄ねじ部３５が形成された筒状部３４とが、一体形成されている。   The accommodating member 31 includes an accommodating portion 32 that accommodates the magnet 19 as a detection object, a cylindrical portion 34 that is formed following the accommodating portion 32, and a spoke 14 that is formed in the radial direction of the cylindrical portion 34. Has a split groove part 33 and a male thread part 35 formed on the outer periphery of the cylindrical part 34. The accommodating member 31 is made of, for example, metal or resin, and an accommodating portion 32 that accommodates the magnet 19 and a cylindrical portion 34 in which the split groove portion 33 and the external thread portion 35 are formed are integrally formed.

また、図１３、図１７などに示すように、連結部材３６は、筒状部３４の雄ねじ部３５に螺合される雌ねじ部３７が内周に形成されたナット形状体で構成されている。連結部材３６は例えば金属製または樹脂製とされている。なお、この実施の形態では、収容部材３１の雄ねじ部３５と連結部材３６の雌ねじ部３７とは互いに対応した直径（同様な直径で、ねじ込み用の隙間分だけ異なる）でテーパ状のねじとされている。そして、図１６に示すように、連結部材３６を収容部材３１の雄ねじ部３５に奥までねじ込んだ際に、連結部材３６がスポーク１４に当接可能に構成されている。   As shown in FIGS. 13 and 17, the connecting member 36 is configured by a nut-shaped body in which an internal thread portion 37 that is screwed into the external thread portion 35 of the cylindrical portion 34 is formed on the inner periphery. The connecting member 36 is made of, for example, metal or resin. In this embodiment, the male threaded portion 35 of the housing member 31 and the female threaded portion 37 of the connecting member 36 are tapered screws with corresponding diameters (similar diameters, differing by a gap for screwing). ing. As shown in FIG. 16, the connecting member 36 is configured to be able to contact the spoke 14 when the connecting member 36 is screwed into the male screw portion 35 of the housing member 31 to the back.

この構成における、当該取付装置３０を介して検出対象体としての磁石１９を後車輪４のスポーク１４に取り付ける手順は以下の通りである。
図１２、図１３などに示すように、まず、磁石１９を収容した収容部材３１の割り溝部３３の奥部にスポーク１４が通るように、収容部材３１をスポーク１４に組み付ける。この後、連結部材３６の雌ねじ部３７を収容部材３１の筒状部３４の雄ねじ部３５にねじ込む。これにより、連結部材３６がスポーク１４側に移動して、割り溝部３３から突出する２箇所の部分で当接する。この結果、収容部材３１の割り溝部２３の底部と連結部材３６のねじ軸部２７の先端部とによりスポーク１４が挟持され、これにより取付装置３０をスポーク１４に固定することができる。 In this configuration, the procedure for attaching the magnet 19 as the detection object to the spoke 14 of the rear wheel 4 through the attachment device 30 is as follows.
As shown in FIGS. 12, 13, and the like, first, the housing member 31 is assembled to the spoke 14 so that the spoke 14 passes through the inner part of the split groove portion 33 of the housing member 31 that houses the magnet 19. Thereafter, the female screw portion 37 of the connecting member 36 is screwed into the male screw portion 35 of the cylindrical portion 34 of the housing member 31. As a result, the connecting member 36 moves to the spoke 14 side and comes into contact with two portions protruding from the split groove portion 33. As a result, the spoke 14 is sandwiched between the bottom portion of the split groove portion 23 of the housing member 31 and the tip end portion of the screw shaft portion 27 of the connecting member 36, whereby the attachment device 30 can be fixed to the spoke 14.

また、この構成によれば、当該取付装置３０を、収容部材３１と、ナット形状体で構成されている連結部材３６との２つの部品で構成できるので、簡単かつコンパクトな構造であるだけでなく、部品点数の低減によって製造コストを抑えたり、当該取付装置３０を取り付ける際の手間や時間を省いたりすることができて作業能率が向上する。   Moreover, according to this structure, since the said attachment apparatus 30 can be comprised by two components of the accommodating member 31 and the connection member 36 comprised by the nut-shaped body, it is not only a simple and compact structure.
