Description

本発明は、自転車錠に関し、特に、自転車の車輪をロックする馬蹄錠等の自転車錠に関するものである。 The present invention relates to a bicycle lock, and more particularly to a bicycle lock such as a horseshoe lock that locks a bicycle wheel.

自転車の車輪をロックする自転車錠として、特許文献1には、円弧形状の閂と、キーシリンダとを備える自転車錠が記載されている。特許文献1に記載の自転車錠においては、閂は、車輪の回転を阻止する施錠位置と車輪の回転阻止を解除する開錠位置とに移動自在である。また、閂は、キーシリンダに連結されている係止部材によって施錠位置に係止される。 As a bicycle lock that locks the wheels of a bicycle, Patent Document 1 describes a bicycle lock including an arc-shaped bar and a key cylinder. In the bicycle lock described in Patent Document 1, the bar is movable between a locking position for blocking the rotation of the wheel and an unlocking position for releasing the rotation blocking of the wheel. Further, the bar is locked at the locked position by a locking member connected to the key cylinder.

特開2019−31881号公報JP-A-2019-31881

しかしながら、特許文献1に記載の自転車錠においては、キーシリンダにおける鍵の回転操作を係止部材の直線運動に変換する変換機構が必要となり、キーシリンダと係止部材との位置関係に一定の制約が生じる。そして、キーシリンダと係止部材との位置関係における制約は、製品としての自転車錠に改良を加える際の大きな障害となり得る。 However, the bicycle lock described in Patent Document 1 requires a conversion mechanism that converts the rotation operation of the key in the key cylinder into the linear motion of the locking member, and there is a certain restriction on the positional relationship between the key cylinder and the locking member. Occurs. The restriction on the positional relationship between the key cylinder and the locking member can be a major obstacle when improving the bicycle lock as a product.

例えば、特許文献1に記載の自転車錠においては、キーシリンダにおける鍵の差込口が自転車の車輪に近接する位置に設けられており、差込口に鍵が差込まれたまま自転車が走行されると、キーホルダの飾り等が車輪に巻き込まれることがあり得る。従って、鍵の差込口を外向きに変更し、鍵の頭部を車輪から遠ざける等の改良が考えられる。 For example, in the bicycle lock described in Patent Document 1, the key insertion port in the key cylinder is provided at a position close to the wheel of the bicycle, and the bicycle runs with the key inserted in the insertion port. Then, the decoration of the key chain or the like may be caught in the wheel. Therefore, improvements such as changing the key insertion port outward and moving the key head away from the wheel can be considered.

ところが、鍵の差込口を外向きに変更すると、自転車が転倒したときに、鍵の頭部が地面に衝突し、鍵から伝わる衝撃によって、キーシリンダが損傷されることもあり得る。キーシリンダの損傷を避けるために、差込口の向きに更なる変更を加えようとするとき、キーシリンダと係止部材との位置関係における制約が障害となり得る。 However, if the key insertion port is changed outward, the head of the key may collide with the ground when the bicycle falls, and the impact transmitted from the key may damage the key cylinder. Constraints on the positional relationship between the key cylinder and the locking member can be an obstacle when attempting to make further changes to the orientation of the outlet to avoid damage to the key cylinder.

本発明は上記課題に鑑みてなされたものであり、その目的は、キーシリンダ、係止部材のような可動部品相互の位置関係に対する制約を解消又は軽減し、製品の改良を容易にできる自転車錠を提供することにある。 The present invention has been made in view of the above problems, and an object of the present invention is to eliminate or reduce restrictions on the positional relationship between moving parts such as key cylinders and locking members, and to facilitate product improvement.

図1に示すように、本実施形態に係る自転車錠1は、閂10と、係止部材20と、受付部30と、変換機構40と、馬蹄形皿状のケース50と、蓋板60とを備える。 As shown in FIG. 1, the bicycle lock 1 according to the present embodiment includes a bar 10, a locking member 20, a reception unit 30, a conversion mechanism 40, a horseshoe-shaped dish-shaped case 50, and a lid plate 60. Be prepared.

図2、図3に示すように、閂10は、自転車の車輪の回転を阻止する施錠位置(図2参照)と車輪の回転阻止を解除する開錠位置(図3参照)とに移動自在である。実施形態においては、閂10は、円弧形状を有し、ケース50の内部に形成されている円弧状のガイド溝51によって案内され、円弧状の移動線L1に沿って移動する。また、閂10は、係止部材20に係合される被係合溝11を有する。 As shown in FIGS. 2 and 3, the bar 10 is movable to a locking position (see FIG. 2) for blocking the rotation of the bicycle wheel and an unlocking position (see FIG. 3) for releasing the wheel rotation blocking. is there. In the embodiment, the bar 10 has an arc shape, is guided by an arc-shaped guide groove 51 formed inside the case 50, and moves along the arc-shaped moving line L1. Further, the bar 10 has an engaged groove 11 that is engaged with the locking member 20.

ケース50は、図1〜図3に示すように、馬蹄形状の中央部側を上側とし、馬蹄形状の両端部側を下側とし、自転車の後輪に対し取付けられる。また、ケース50は、略同一の輪郭形状を有する蓋板60との間に、閂10等の各部材を収容する収容空間を形成する。閂10の移動線L1は、蓋板60における収容空間側の表面と平行である。すなわち、移動線L1は、蓋板60における収容空間側の表面と平行である平面に含まれる。 As shown in FIGS. 1 to 3, the case 50 is attached to the rear wheel of the bicycle with the central portion side of the horseshoe shape on the upper side and both end sides of the horseshoe shape on the lower side. Further, the case 50 forms a storage space for accommodating each member such as a bar 10 between the case 50 and the lid plate 60 having substantially the same contour shape. The movement line L1 of the bar 10 is parallel to the surface of the lid plate 60 on the accommodation space side. That is, the moving line L1 is included in a plane parallel to the surface of the lid plate 60 on the accommodation space side.

ガイド溝51は、一端部51a及び他端部51bが開口している。一端部51aと他端部51bとは、自転車のタイヤ幅よりも大きい所定の間隔をあけて対向している。図2に示すように、閂10が施錠位置にあるとき、閂10は、ガイド溝51の一端部51aと他端部51bとの間に掛け渡された状態となる。また、図3に示すように、閂10が開錠位置にあるとき、閂10の略全体がケース50の内部に位置し、一端部51aと他端部51bとの間の空間は開放された状態となる。 The guide groove 51 has one end 51a and the other end 51b open. One end 51a and the other end 51b face each other with a predetermined distance larger than the tire width of the bicycle. As shown in FIG. 2, when the bar 10 is in the locked position, the bar 10 is in a state of being hung between one end 51a and the other end 51b of the guide groove 51. Further, as shown in FIG. 3, when the bar 10 is in the unlocked position, substantially the entire bar 10 is located inside the case 50, and the space between the one end 51a and the other end 51b is opened. It becomes a state.

また、図1に示すように、閂10には摘み軸10aが設けられており、摘み軸10aには、摘み12が取付けられる。摘み12は、閂10を開錠位置から施錠位置に移動する操作を受付ける。閂10が開錠位置から施錠位置に移動されると、閂10は、車輪の側方からスポークの間に差し込まれ、車輪の回転を阻止する。また、閂10は、閂バネ13によって、開錠位置に向かって付勢されている。 Further, as shown in FIG. 1, the bar 10 is provided with a knob shaft 10a, and the knob 12 is attached to the grip shaft 10a. The knob 12 accepts an operation of moving the bar 10 from the unlocked position to the locked position. When the bar 10 is moved from the unlocked position to the locked position, the bar 10 is inserted between the spokes from the side of the wheel to prevent the wheel from rotating. Further, the bar 10 is urged toward the unlocking position by the bar spring 13.

係止部材20は、図2、図3に示すように、閂10に係合し施錠位置に閂10を係止する係止位置(図2参照)と閂10の係止を解除する非係止位置(図3参照)とに所定の直線Lに沿って移動自在である。係止位置においては、係止部材20は、閂10の被係合溝11に係合する。また、係止部材20は、係止バネ24によって、係止位置に向かって付勢されており、閂10が開錠位置から施錠位置に移動されると、係止部材20は、係止バネ24の付勢力によって自動的に係止位置に移動し、被係合溝11に係合する。 As shown in FIGS. 2 and 3, the locking member 20 is unrelated to the locking position (see FIG. 2) that engages with the bar 10 and locks the bar 10 at the locking position, and unlocks the bar 10. It is movable along a predetermined straight line L at the stop position (see FIG. 3). At the locking position, the locking member 20 engages with the engaged groove 11 of the bar 10. Further, the locking member 20 is urged toward the locking position by the locking spring 24, and when the bar 10 is moved from the unlocking position to the locking position, the locking member 20 is displaced by the locking spring. The urging force of 24 automatically moves to the locking position and engages with the engaged groove 11.

受付部30は、図4に示すように、回転体31を有し、係止部材20を直線Lに沿って移動させるための移動操作として、回転体31を回転する回転操作を受付ける。回転体31は、所定の回転軸線Sを中心として回転する。実施形態においては、受付部30は、キーシリンダであり、スペーサ52の嵌合部52aに嵌合され、スペーサ52に保持され、ケース50に取付けられる。 As shown in FIG. 4, the receiving unit 30 has a rotating body 31, and receives a rotating operation for rotating the rotating body 31 as a moving operation for moving the locking member 20 along the straight line L. The rotating body 31 rotates about a predetermined rotation axis S. In the embodiment, the receiving portion 30 is a key cylinder, is fitted to the fitting portion 52a of the spacer 52, is held by the spacer 52, and is attached to the case 50.

回転体31は、鍵Kの差込口を有するシリンダであり、施錠状態と解錠状態との間で回転可能であり、係止部材20の直線運動と連動して回転する。すなわち、閂10が施錠位置に移動され、係止部材20が係止位置に移動するとき、回転体31は施錠状態に回転され、受付部30を構成するキーシリンダが施錠され、鍵Kは、抜き差し可能となる。鍵Kによって回転体31が解錠状態に回転されると、係止部材20が非係止位置に移動し、閂10が開錠位置に移動し、鍵Kは、引き抜き不能となる。なお、鍵Kは、回転体31が解錠状態であるときにおいても、抜き差し可能としてよい。 The rotating body 31 is a cylinder having an insertion port for the key K, is rotatable between the locked state and the unlocked state, and rotates in conjunction with the linear motion of the locking member 20. That is, when the bar 10 is moved to the locked position and the locking member 20 is moved to the locked position, the rotating body 31 is rotated to the locked state, the key cylinder constituting the reception unit 30 is locked, and the key K is It can be inserted and removed. When the rotating body 31 is rotated in the unlocked state by the key K, the locking member 20 moves to the unlocked position, the bar 10 moves to the unlocked position, and the key K cannot be pulled out. The key K may be inserted and removed even when the rotating body 31 is in the unlocked state.

また、実施形態においては、図1に示すように、受付部30は、ケース50の上端部近傍に配設され、回転体31の回転軸線Sは、閂10の移動線L1を含む平面に対し斜めに交差し、鍵Kの差込口は閂10の移動線L1を含む平面に対し斜め上に向いている。 Further, in the embodiment, as shown in FIG. 1, the reception portion 30 is arranged near the upper end portion of the case 50, and the rotation axis S of the rotating body 31 is relative to the plane including the movement line L1 of the bar 10. It intersects diagonally, and the insertion port of the key K faces diagonally upward with respect to the plane including the movement line L1 of the bar 10.

変換機構40は、受付部30に対する回転操作を係止部材20の直線運動に変換する。また、上述したとおり、変換機構40は、係止部材20の直線運動を回転体31の回転運動に変換する。そして、図4に示すように、回転軸線Sに対応する第1方向ベクトルV1と係止部材20の直線運動に対応する第2方向ベクトルV2、すなわち直線Lに対応する第2方向ベクトルV2とは、鋭角又は鈍角である角αで交差する。実施形態においては、第1方向ベクトルV1は、鍵Kの差込口の向きに対応し、第2方向ベクトルV2は、非係止位置から係止位置に向かう方向に対応する。 The conversion mechanism 40 converts the rotation operation with respect to the reception unit 30 into a linear motion of the locking member 20. Further, as described above, the conversion mechanism 40 converts the linear motion of the locking member 20 into the rotational motion of the rotating body 31. Then, as shown in FIG. 4, the first direction vector V1 corresponding to the rotation axis S and the second direction vector V2 corresponding to the linear motion of the locking member 20, that is, the second direction vector V2 corresponding to the straight line L are Cross at an angle α, which is a sharp or obtuse angle. In the embodiment, the first direction vector V1 corresponds to the direction of the key K outlet, and the second direction vector V2 corresponds to the direction from the unlocked position to the locked position.

以上、図1〜図4を参照して説明したように、本実施形態の自転車錠によれば、回転軸線Sに対応する第1方向ベクトルV1と係止部材20の直線運動に対応する第2方向ベクトルV2とが鋭角又は鈍角である角αで交差する。従って、受付部30に対する回転操作の中心線である回転軸線Sを係止部材20における直線運動に沿った直線Lに対し傾けることができ、可動部品相互の位置関係に対する制約を解消又は軽減し、製品としての自転車錠の改良を容易にできる。 As described above with reference to FIGS. 1 to 4, according to the bicycle lock of the present embodiment, the first direction vector V1 corresponding to the rotation axis S and the second direction vector V1 corresponding to the linear motion of the locking member 20 correspond to the linear motion. The direction vector V2 intersects at an acute angle or an obtuse angle α. Therefore, the rotation axis S, which is the center line of the rotation operation with respect to the reception unit 30, can be tilted with respect to the straight line L along the linear motion of the locking member 20, and the restriction on the positional relationship between the moving parts can be eliminated or reduced. The bicycle lock as a product can be easily improved.

例えば、特許文献1に示されているように、従来の自転車錠においては、受付部としてのキーシリンダの回転軸線と係止部材の直線運動の方向とが直交しており、キーシリンダにおける鍵の差込口の向きは、円弧状の閂の移動線を含む平面に対し直交する方向に限定されている。従って、図8に示すように、従来の自転車錠100を自転車における後輪の中心より後方に設置すると、キーシリンダにおける鍵の差込口の向き(一点鎖線S1に対応する方向)が水平方向より下向きとなり、差込口が視認しづらく、鍵を差し込みにくくなるのに対し、本実施形態の自転車錠1によれば、角αを適宜の角度に設定することによって、キーシリンダにおける鍵の差込口の向きを水平方向又は水平方向よりも上向きにすることができ、鍵Kが差し込みやすくするように、製品としての自転車錠の改良を容易にできる。 For example, as shown in Patent Document 1, in a conventional bicycle lock, the rotation axis of the key cylinder as a receiving portion and the direction of linear motion of the locking member are orthogonal to each other, and the key in the key cylinder The direction of the insertion port is limited to the direction orthogonal to the plane including the movement line of the arc-shaped bar. Therefore, as shown in FIG. 8, when the conventional bicycle lock 100 is installed behind the center of the rear wheel of the bicycle, the direction of the key insertion port in the key cylinder (the direction corresponding to the one-point chain line S1) is from the horizontal direction. The key is inserted in the key cylinder by setting the angle α to an appropriate angle according to the bicycle lock 1 of the present embodiment, whereas the insertion port is downward and the insertion port is difficult to see and the key is difficult to insert. The direction of the mouth can be horizontal or higher than the horizontal direction, and the bicycle lock as a product can be easily improved so that the key K can be easily inserted.

また、図1〜4に示されているように、実施形態の自転車錠1においては、閂10が、円弧形状を有し、円弧状の移動線L1に沿って移動し、受付部30が、キーシリンダを含み、直線Lが上下方向に沿って延びており、回転軸線Sが、移動線L1を含む平面に交差する方向に延びており、第1方向ベクトルV1が、鍵Kの差込口の向きに対応し、第2方向ベクトルV2が、非係止位置から係止位置に向かう方向に対応し、第1方向ベクトルV1と第2方向ベクトルV2とが成す角αが、鈍角である。従って、キーシリンダにおける鍵の差込口の向きを水平方向又は水平方向よりも上向きにすることができ、鍵Kが差し込みやすくするように、製品としての自転車錠の改良を容易にできる。なお、直線Lは、必ずしも上下方向に平行である必要はなく、例えば45度以内の角度で上下方向に対し傾いていてもよい。 Further, as shown in FIGS. 1 to 4, in the bicycle lock 1 of the embodiment, the bar 10 has an arc shape and moves along the arc-shaped movement line L1, and the reception unit 30 has an arc shape. The straight line L extends along the vertical direction including the key cylinder, the rotation axis S extends in the direction intersecting the plane including the movement line L1, and the first direction vector V1 is the insertion port of the key K. The second direction vector V2 corresponds to the direction from the non-locking position to the locking position, and the angle α formed by the first direction vector V1 and the second direction vector V2 is a blunt angle. Therefore, the direction of the key insertion port in the key cylinder can be horizontal or higher than the horizontal direction, and the bicycle lock as a product can be easily improved so that the key K can be easily inserted. The straight line L does not necessarily have to be parallel in the vertical direction, and may be inclined with respect to the vertical direction at an angle of, for example, within 45 degrees.

また、特許文献1に記載の自転車錠においては、キーシリンダの設置位置が自転車錠の下端部にあり、鍵の差込口が車輪に近接しており、キーホルダの飾り等が車輪に巻き込まれやすいのに対し、本実施形態の自転車錠1によれば、図1〜図3に示すように、キーシリンダである受付部30が、自転車錠1における上端部の近傍に設置され、鍵Kの差込口と車輪との間に一定の距離を空けることが容易である。従って、鍵Kが差込口に差し込まれたまま自転車が走行されても、キーホルダの飾り等が車輪に巻き込まれることを防止でき、自転車の走行が妨げられることを防止できる。 Further, in the bicycle lock described in Patent Document 1, the key cylinder is installed at the lower end of the bicycle lock, the key insertion port is close to the wheel, and the decoration of the key holder or the like is easily caught in the wheel. On the other hand, according to the bicycle lock 1 of the present embodiment, as shown in FIGS. 1 to 3, the reception portion 30 which is a key cylinder is installed near the upper end portion of the bicycle lock 1, and the difference between the keys K is It is easy to leave a certain distance between the inlet and the wheel. Therefore, even if the bicycle is driven with the key K inserted into the insertion slot, it is possible to prevent the decoration of the key chain and the like from being caught in the wheels, and it is possible to prevent the bicycle from being hindered from traveling.

次に、図1、図4を参照して、本発明の他の実施形態を説明する。本実施形態においては、変換機構40は、回転レバー41と、ガイド部42とを有する。回転レバー41は、係合突部41aと、支持部41bとを有し、回転体31と一体的に回転する。係合突部41aは、回転軸線Sに対し偏心配置され、係止部材20を駆動可能に係止部材20に係合する。支持部41bは、回転体31に嵌合する嵌合部を有しており、回転軸線Sを中心として回動可能に係合突部41aを回転体31に支持する。また、支持部41bは、回転軸線Sに沿って見たとき、輪郭形状は円形となっており、係合突部41aは、支持部41bの輪郭円周に内側から接するように配設される。ガイド部42は、係止部材20に摺接し、係止部材20の直線運動を案内する。 Next, another embodiment of the present invention will be described with reference to FIGS. 1 and 4. In the present embodiment, the conversion mechanism 40 has a rotary lever 41 and a guide portion 42. The rotary lever 41 has an engaging protrusion 41a and a support portion 41b, and rotates integrally with the rotating body 31. The engaging protrusion 41a is eccentrically arranged with respect to the rotation axis S, and engages the locking member 20 with the locking member 20 so as to be driveable. The support portion 41b has a fitting portion that fits into the rotating body 31, and supports the engaging protrusion 41a on the rotating body 31 so as to be rotatable around the rotation axis S. Further, the support portion 41b has a circular contour shape when viewed along the rotation axis S, and the engaging protrusion 41a is arranged so as to be in contact with the contour circumference of the support portion 41b from the inside. .. The guide portion 42 is in sliding contact with the locking member 20 to guide the linear motion of the locking member 20.

実施形態においては、回転レバー41の係合突部41aは、先端部が斜めにカットされた丸棒状の部材であり、回転軸線Sと平行に延びている。係合突部41aの先端部が斜めにカットされている理由は、回転体31が施錠状態又は解錠状態に回転されるときに、係合突部41aの先端部が他部材に干渉することを避けるためである。また、支持部41bは、回転軸線Sに対し傾斜する傾斜面部41cを有する。傾斜面部41cは、係止部材20に摺接する。また、傾斜面部41cは、支持部41bにおける中心側が外周側より高い山形を成すように傾斜の向きが設定される。傾斜面部41cが設けられることにより、回転レバー41は、支持部41bに円錐状又は円錐台状の***が形成されることとなり、そして、その傾斜面部41cの一部より係合突部41aが突設される。 In the embodiment, the engaging protrusion 41a of the rotary lever 41 is a round bar-shaped member whose tip is obliquely cut, and extends parallel to the rotation axis S. The reason why the tip of the engaging protrusion 41a is cut diagonally is that the tip of the engaging protrusion 41a interferes with other members when the rotating body 31 is rotated in the locked or unlocked state. This is to avoid. Further, the support portion 41b has an inclined surface portion 41c that is inclined with respect to the rotation axis S. The inclined surface portion 41c is in sliding contact with the locking member 20. Further, the inclination direction of the inclined surface portion 41c is set so that the central side of the supporting portion 41b forms a mountain shape higher than the outer peripheral side. By providing the inclined surface portion 41c, the rotary lever 41 is formed with a conical or truncated cone-shaped ridge on the support portion 41b, and the engaging protrusion 41a protrudes from a part of the inclined surface portion 41c. Will be set up.

また、係止部材20は、被係合部21と、係合軸部22と、被ガイド部23とを有する。被係合部21は、回転レバー41の係合突部41aに係合される。実施形態においては、被係合部21は、回転軸線Sに沿って延びる溝状であり、被係合部21が延びる方向における両端部のうち、少なくとも回転レバー41側の端部は開口している。係合突部41aは、被係合部21における回転レバー41側の端部開口を介し被係合部21に差込まれている。 Further, the locking member 20 has an engaged portion 21, an engaging shaft portion 22, and a guided portion 23. The engaged portion 21 is engaged with the engaging protrusion 41a of the rotary lever 41. In the embodiment, the engaged portion 21 has a groove shape extending along the rotation axis S, and at least the end portion on the rotating lever 41 side of both ends in the extending direction of the engaged portion 21 is opened. There is. The engaging protrusion 41a is inserted into the engaged portion 21 through the end opening on the rotating lever 41 side of the engaged portion 21.

係合軸部22は、閂10を施錠位置に係止可能に閂10に係合する。実施形態においては、係合軸部22は、閂10の被係合溝11に係合する。被ガイド部23は、ガイド部42に摺接される。被ガイド部23が、ガイド部42に摺接されることによって、係止部材20の直線運動がガイドされる。そして、回転レバー41の傾斜面部41cは、係止部材20が係止位置に位置するとき、被ガイド部23に当接する。 The engaging shaft portion 22 engages with the bar 10 so that the bar 10 can be locked at the locked position. In the embodiment, the engaging shaft portion 22 engages with the engaged groove 11 of the bar 10. The guided portion 23 is in sliding contact with the guide portion 42. The linear motion of the locking member 20 is guided by the guided portion 23 being slidably contacted with the guide portion 42. Then, the inclined surface portion 41c of the rotary lever 41 comes into contact with the guided portion 23 when the locking member 20 is located at the locking position.

以上、図1、図4を参照して説明したように、本実施形態の自転車錠によれば、係止部材20を駆動する回転レバー41が、係止部材20が係止位置に位置するときに被ガイド部23に当接する傾斜面部41cを有している。従って、係止部材20が施錠位置に閂10を係止しているときに、係止部材20の姿勢を安定的に維持することができ、例えば自転車錠の施錠状態において閂10に外力が加わったときに、直線Lに対し係止部材20が傾いてしまい、閂10と係止部材20との係合が解除され、自転車錠が外力によって開錠されることを防止できる。 As described above with reference to FIGS. 1 and 4, according to the bicycle lock of the present embodiment, when the rotary lever 41 for driving the locking member 20 is located at the locking position of the locking member 20. Has an inclined surface portion 41c that abuts on the guided portion 23. Therefore, when the locking member 20 locks the bar 10 at the locking position, the posture of the locking member 20 can be stably maintained. For example, an external force is applied to the bar 10 in the locked state of the bicycle lock. At that time, the locking member 20 is tilted with respect to the straight line L, the engagement between the bar 10 and the locking member 20 is released, and the bicycle lock can be prevented from being unlocked by an external force.

すなわち、特許文献1に示されている従来の自転車錠においては、キーシリンダの回転軸線と係止部材の移動方向とが直交していることから、回転レバーにおける円板状の支持部が係止部材に常に当接し、係止部材の姿勢は安定的に維持される。本実施形態の自転車錠においては、回転軸線Sと直線Lとが直交しておらず、斜めに交差している。従って、支持部41bが単なる円板状であると、支持部41bが係止部材20に当接せず、係止部材20の姿勢を安定的に維持することが困難になることもあり得る。本実施形態の自転車錠によれば、支持部41bに傾斜面部41cが形成されており、係止部材20が係止位置に位置するときに、傾斜面部41cが係止部材20の被ガイド部23に当接する。従って、係止部材20の姿勢を安定的に維持でき、自転車錠における施錠状態を安定的に維持できる。 That is, in the conventional bicycle lock shown in Patent Document 1, since the rotation axis of the key cylinder and the moving direction of the locking member are orthogonal to each other, the disk-shaped support portion of the rotating lever is locked. It always contacts the member, and the posture of the locking member is maintained stably. In the bicycle lock of the present embodiment, the rotation axis S and the straight line L are not orthogonal to each other and intersect diagonally. Therefore, if the support portion 41b is merely a disk shape, the support portion 41b may not come into contact with the locking member 20, and it may be difficult to maintain a stable posture of the locking member 20. According to the bicycle lock of the present embodiment, the inclined surface portion 41c is formed on the support portion 41b, and when the locking member 20 is located at the locking position, the inclined surface portion 41c is the guided portion 23 of the locking member 20. To abut. Therefore, the posture of the locking member 20 can be stably maintained, and the locked state of the bicycle lock can be stably maintained.

また、本実施形態においては、図2、図3に示すように、傾斜面部41cは、被ガイド部23に対し線接触可能に、支持部41bに形成されている。傾斜面部41cが被ガイド部23に対し線接触可能であることによって、係止部材20の姿勢をより安定的に維持でき、自転車錠における施錠状態をより安定的に維持できる。なお、傾斜面部41cが、被ガイド部23に対し線接触可能であることは必須ではなく、傾斜面部41cは、被ガイド部23に対し点接触可能に、支持部41bに形成されてもよい。すなわち、傾斜面部41cは、支持部41bの中心側に向かうに連れて、傾斜が緩やかになるように形成されてもよい。 Further, in the present embodiment, as shown in FIGS. 2 and 3, the inclined surface portion 41c is formed on the support portion 41b so as to be in line contact with the guided portion 23. Since the inclined surface portion 41c can make line contact with the guided portion 23, the posture of the locking member 20 can be maintained more stably, and the locked state of the bicycle lock can be maintained more stably. It is not essential that the inclined surface portion 41c can make line contact with the guided portion 23, and the inclined surface portion 41c may be formed on the supporting portion 41b so as to make point contact with the guided portion 23. That is, the inclined surface portion 41c may be formed so that the inclination becomes gentle toward the center side of the support portion 41b.

次に、図5〜図7を参照して、本発明の更に他の実施形態を説明する。図5は、本発明の他の実施形態に係る自転車錠を示す分解斜視図である。図6(a)は、施錠状態における図5の自転車錠を示す正面図である。図6(b)は、図6(a)のD−D線断面図である。図7(a)は、開錠状態における図5の自転車錠を示す正面図である。図7(b)は、図7(a)のE−E線断面図である。 Next, still another embodiment of the present invention will be described with reference to FIGS. 5 to 7. FIG. 5 is an exploded perspective view showing a bicycle lock according to another embodiment of the present invention. FIG. 6A is a front view showing the bicycle lock of FIG. 5 in the locked state. FIG. 6B is a sectional view taken along line DD of FIG. 6A. FIG. 7A is a front view showing the bicycle lock of FIG. 5 in the unlocked state. FIG. 7B is a cross-sectional view taken along the line EE of FIG. 7A.

図5〜図7に示すように、本実施形態の自転車錠1Aは、受付部30が、ケース50における下端部の近傍に配設され、回転軸線Sが、閂10の移動線L1を含む平面に沿って延びており、角αが、鋭角である点において、図1の自転車錠1とは異なる。それ以外の点は、自転車錠1Aは、図1の自転車錠1と同様である。 As shown in FIGS. 5 to 7, in the bicycle lock 1A of the present embodiment, the reception portion 30 is arranged in the vicinity of the lower end portion of the case 50, and the rotation axis S is a plane including the movement line L1 of the bar 10. It differs from the bicycle lock 1 of FIG. 1 in that the angle α extends along the bicycle lock 1 and has an acute angle. Other than that, the bicycle lock 1A is the same as the bicycle lock 1 of FIG.

以上、図5〜図7を参照して説明したように、本実施形態の自転車錠においては、閂10が、円弧形状を有し、円弧状の移動線L1に沿って移動し、受付部30が、キーシリンダを含み、回転軸線Sが、移動線L1を含む平面に沿って延びており、第1方向ベクトルV1が、鍵Kの差込口の向きに対応し、第2方向ベクトルV2が、非係止位置から係止位置に向かう方向に対応し、第1方向ベクトルV1と第2方向ベクトルV2とが成す角αが、鋭角である。従って、図6に示すように、自転車錠1Aの施錠状態において、鍵Kの頭部が、ケース50の側端部50aよりも側方に突出しないように自転車錠を設計することが容易になり、鍵Kがキーシリンダに差し込まれたまま自転車が転倒しても、鍵Kの頭部が地面に衝突することを防止でき、受付部30が損傷されることを防止できる。 As described above with reference to FIGS. 5 to 7, in the bicycle lock of the present embodiment, the bar 10 has an arc shape and moves along the arc-shaped movement line L1, and the reception unit 30 However, the rotation axis S extends along the plane including the movement line L1 including the key cylinder, the first direction vector V1 corresponds to the direction of the insertion port of the key K, and the second direction vector V2 The angle α formed by the first direction vector V1 and the second direction vector V2 corresponds to the direction from the unlocked position to the locked position, and is a sharp angle. Therefore, as shown in FIG. 6, it becomes easy to design the bicycle lock so that the head of the key K does not protrude laterally from the side end portion 50a of the case 50 in the locked state of the bicycle lock 1A. Even if the bicycle falls while the key K is inserted in the key cylinder, it is possible to prevent the head of the key K from colliding with the ground and prevent the reception portion 30 from being damaged.

以上、図面(図1〜図8)を参照しながら本発明の実施形態を説明した。但し、本発明は、上記の実施形態に限られるものではなく、その要旨を逸脱しない範囲で種々の態様において実施することが可能である。 The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 8). However, the present invention is not limited to the above-described embodiment, and can be implemented in various embodiments without departing from the gist thereof.
