Description

【0001】
【発明の属する技術分野】
この発明は、自転車等の二輪車を上下二段に駐輪する駐輪装置に関するものである。
【0002】
【従来の技術】
二輪車を上下二段に駐輪する駐輪装置には様々な形態のものがあるが、比較的構造が簡単であるという理由から、床面から所定の高さ位置で水平に支持された固定フレームと、固定フレームに沿って前後に進退自在な可動フレームとを備え、可動フレームを固定フレームの先端側に後退させ、その前端部を回動中心として後端側を下方に回動させて二輪車を載せ、こののち、この後端側を上方に概ね水平位置まで回動させ、この水平位置まで回動させた可動フレームを、固定フレームの基端側へ前進させて二輪車を収納するタイプのものが、特に自転車を主たる対象として多く採用されている。
【0003】
この種の駐輪装置では、当初、自転車を載せた可動フレームを上方に回動させる補助力を作用させるために、可動フレームをばねで固定フレームに連結して、可動フレームを上方へ付勢する工夫がなされた。
【0004】
上記のように、可動フレームをばねで固定フレームに連結した当初の駐輪装置は、可動フレームを固定フレームの先端側へ引き出す際に、ばね力が抵抗となって可動フレームの引き出しが重くなる難点があり、さらに、この難点を解消するために、ばね力を可動フレームの回動にのみ作用させる工夫がなされている。
【0005】
この種の駐輪装置としては、例えば、特許公報第2628675号や特許公報第2736513号に記載されたものがある。前者は、図9に示すように、固定フレーム51(ベース部材)にレール部材52が取り付けられ、可動フレーム53(載置部材)の前端部に取り付けられたガイドコマ54がレール部材52に進退自在に係合されるとともに、可動フレーム53の後端部に、固定フレーム51の基端側へ向けて、先端に引掛け爪状のロック体55が設けられた引張コイルばね56が取り付けられ、固定フレーム51の先端部にロック体55が係止されるロック受け体57が設けられている。
【0006】
この駐輪装置では、可動フレーム53を固定フレーム51の先端側に後退させたときに、ロック体55がロック受け体57に係止され、ガイドコマ54を回動支点として可動フレーム53の後端側を下方に回動すると、コイルばね56により可動フレーム53の後端側が上方に付勢されるようになっている。すなわち、この駐輪装置は、可動フレーム53を回動するときのみ、コイルばね56を固定フレーム51と連結することにより、ばね力を可動フレーム53の回動にのみ作用させるようにしている。
【0007】
後者は、図10に示すように、固定フレーム58がリップ付き溝形鋼で形成され、その先端部に可動フレーム59のガイド溝60に嵌め込まれる遊転ローラ61が取り付けられている。可動フレーム59の前端側には、揺動フレーム62が枢軸63により前後揺動自在に枢着され、揺動フレーム62の揺動先端部には、固定フレーム58のリップと底壁の間に嵌め込まれる転動ローラ64が取り付けられ、さらに、この揺動先端部が引張コイルばね65により、可動フレーム59前端側の枢軸63から後寄りの位置に連結されている。
【0008】
したがって、この駐輪装置では、可動フレーム59と揺動フレーム62とが一緒に、前端側を共に移動する転動ローラ64で支持され、後端側を固定フレーム58に固定された遊転ローラ61で支持されながら、固定フレーム58に沿って前後に進退し、固定フレーム58の先端側に後退したときに、遊転ローラ61を回動中心として、可動フレーム59の後端側を下方に回動すると、回動中心よりも前端側がコイルばね65により下方に引っ張られ、可動フレーム59の後端側が上方に付勢される。すなわち、この駐輪装置は、コイルばね65を可動フレーム59と一緒に進退する揺動フレーム62と連結することにより、ばね力を可動フレーム59の回動にのみ作用させるようにしている。
【0009】
【発明が解決しようとする課題】
上述した従来の駐輪装置は、いずれも可動フレームの回動時のみにばね力を作用させて、自転車を載置した可動フレームの上方への回動を楽にするものであるが、前者は、コイルばねの基端を可動フレームの後端部に取り付けているので、非常に長いコイルばねを必要とし、かつ、この長いコイルばねが可動フレームとともに移動するので損傷しやすい問題がある。また、後者は、コイルばねを連結する揺動フレームを余分に必要とし、かつ、この揺動フレームが可動フレームに対して揺動するので、その揺動を抑えて固定フレームに沿う進退を案内する必要もあり、構造が複雑となる問題がある。
【0010】
そこで、この発明の課題は、メインテナンス性に優れ、シンプルな構造で可動フレームの回動補助力が得られる駐輪装置を提供することである。
【0011】
【課題を解決するための手段】
上記の課題を解決するために、この発明は、床面から所定の高さ位置に、先端を概ね水平に向けて支持された固定フレームと、固定フレームに沿って前後に進退自在な可動フレームとを備え、可動フレームを固定フレームの先端側に後退させ、その前端部を回動中心として後端側を下方に回動させて自転車を載せ、こののち、この後端側を上方に概ね水平位置まで回動させ、この水平位置まで回動させた可動フレームを、固定フレームの基端側へ前進させて二輪車を収納する駐輪装置において、前記固定フレームの先端部に、先端部が自由状態の引張ばねを、その先端部が前記可動フレームの下側に位置し、かつ、固定フレームの基端側へ向くように取り付け、この引張ばねの先端部と、前記可動フレームの前端部の下側の前記回動中心よりも前端寄りの係止部位とに、この係止部位の水平方向への移動に対しては係脱自在で、係止部位の上方向への移動に対してのみ、係止部位が前記引張ばねの先端部に係止される手段を設け、前記可動フレームが前記固定フレームの先端側に後退して、その後端側が下方に回動するときに、前記係止部位を前記引張ばねの先端部に係止し、この可動フレームの後端側が下方に回動した状態で、前記回動中心よりも前端側を前記引張ばねにより下方に引っ張り、可動フレームの後端側を上方に回動する方向に付勢する構成を採用した。
【0012】
すなわち、固定フレームの先端部に、先端部が自由状態の引張ばねを、その先端部が固定フレームの基端側へ向くように取り付け、この引張ばねの先端部と、可動フレームの前端部の回動中心よりも前端寄りの係止部位とに、係止部位の水平方向への移動に対しては係脱自在で、係止部位の上方向への移動に対してのみ、係止部位が引張ばねの先端部に係止される手段を設け、可動フレームの後端側が下方に回動されるときに、係止部位を引張ばねの先端部に係止して、引張ばねにより下方に引っ張ることにより、余分な部材を必要としないシンプルな構成で、可動フレームの後端側を上方に付勢できるようにした。
【0013】
前記係止部位の水平方向への移動に対しては係脱自在で、係止部位の上方向への移動に対してのみ、係止部位を前記引張ばねの先端部に係止する手段としては、前記引張ばねの先端部に下向きに開く鉤部材を前記係止部位に向けて取り付け、前記係止部位にこの鉤部材の鉤底に受け止められる鉤受け部材を取り付け、この鉤受け部材が前記鉤部材の鉤先を水平方向に通り抜け可能とする方法、または、前記係止部位に上向きに開く鉤部材を前記引張ばねの先端部に向けて取り付け、前記引張ばねの先端部にこの鉤部材の鉤底に受け止められる鉤受け部材を取り付け、この鉤受け部材が前記鉤部材の鉤先を水平方向に通り抜け可能とする方法を採用することができる。
【0014】
前記鉤受け部材が前記鉤部材の鉤先を水平方向に通り抜け可能とする手段としては、前記鉤受け部材を、前記鉤部材の鉤先を水平方向に通過する高さ位置に配置する方法や、前記鉤部材の鉤先の前後面または、前記鉤受け部材の前記鉤底に受け止められる側の前後面の少なくともいずれか一方に傾斜逃げ面を形成し、前記鉤部材の鉤先または前記鉤受け部材を上下方向に逃がして、前記鉤受け部材を、前記鉤部材の鉤先を通り抜けさせる方法を採用することができる。なお、傾斜逃げ面は曲面でもよい。
【0015】
【発明の実施の形態】
以下、図1乃至図8に基づき、この発明の実施形態を説明する。この駐輪装置は、自転車を上下二段に駐輪するものであり、図1および図2に示すように、床面上に立設された所定高さの支柱1の上端に、上段側の駐輪用固定フレーム2が先端を水平に向けて取り付けられ、下端に床面に沿って下段側の駐輪用固定フレーム3が取り付けられている。上段側の固定フレーム2には、自転車を載せる可動フレーム4が前後に進退自在に取り付けられ、可動フレーム4を固定フレーム2の先端側に後退させたときに、可動フレーム4の後端側が下方に回動されるようになっている。可動フレーム4の上面側には、自転車の前後輪をそれぞれ固定する輪止め5a、5bが設けられ、可動フレーム4の後端には、可動フレーム4を引き出して回動させる把手6が設けられている。
【0016】
図3および図4に示すように、固定フレーム2と可動フレーム4にはいずれも軽量形鋼が使用され、固定フレーム2は軽溝形鋼の左右縦壁に内向きコ字断面の案内レール部7を形成したもの、可動フレーム4はハット形鋼を上向きにしたものである。
【0017】
前記固定フレーム2は、その基端側を受け板8を介して支柱1の上端に取り付けられ、その先端部の左右縦壁に差し渡した軸9に左右一対の支持ローラ10が回転自在に嵌め込まれている。各支持ローラ10は、中央側に可動フレーム4の底面を支持する輪部10aが形成され、端部側に可動フレーム4の側面を案内する鍔部10bが形成されている。
【0018】
また、固定フレーム2の先端部の底壁下面には、下向きに開く鉤部材11を先端に取り付けられた引張コイルばね12が、ブラケット13を介して上下に首振り自在に取り付けられ、底壁に設けられた開口14を通して、先端の鉤部材11が固定フレーム2の内側で固定フレーム2の基端側に向けて配置されている。開口14の前端縁には傾斜台板15が取り付けられており、コイルばね12は台板15に上向きに傾斜して載せられ、先端の鉤部材11が固定フレーム2の底から浮かされている。
【0019】
前記可動フレーム4の前端部の左右縦壁には、固定フレーム2の案内レール部7に案内される左右一対の車輪16が取り付けられており、可動フレーム4はこの車輪16と支持ローラ10とにより前後を支持されて進退する。なお、固定フレーム2の基端には可動フレーム4の前端を止めるストッパ板17が設けられ、案内レール部7の先端には、車輪16の抜け落ちを止めるストッパ板18が設けられている。
【0020】
また、可動フレーム4の車輪16よりも前端側の底壁下面には、ブラケット19を介して鉤受け部材としての水平ピン20が取り付けられている。この水平ピン20は、図5に示すように、鉤部材11の鉤先よりも低い位置に取り付けられており、可動フレーム4を固定フレーム2の先端側に後退させたときに、水平ピン20は鉤部材11の鉤先の下方を通過して、下向きに開く鉤部材11の下に入り込むようになっている。なお、鉤部材11の鉤先前後の曲面と水平ピン20の上側前後の円筒面とは、そのままの形で傾斜逃げ面となっているので、両者は多少干渉する高さ位置関係にあってもよく、この場合は、水平ピン20が鉤先を少し押し上げて鉤部材11の下に入り込む。
【0021】
前記ブラケット19は、図6に示すように、固定フレーム2の先端側へ八字状に開く一対の板材で形成されており、鉤部材11がスムーズに水平ピン20の上方に案内されるようになっている。
【0022】
図5に示した状態で、可動フレーム4の後端に設けられた把手6を下方に押し下げることにより、図7に示すように、可動フレーム4は支持ローラ10を支点として、その後端側が下方に回動する。このとき、水平ピン20が鉤部材11の鉤底に係止され、コイルばね12が引き伸ばされて、可動フレーム4は回動中心よりも前端側を下方に引っ張られ、後端側が上方に回動する方向に付勢される。
【0023】
図8は、前記鉤部材11と鉤受け部材の変形例を示す。図8(a)は、可動フレーム4の前端側の底壁下面に、上向きに開く鉤部材11aをコイルばね12の先端部に向けて取り付け、コイルばね12の先端部に鉤受け部材としてのリング20aを、鉤部材11aの鉤先よりも高い位置に取り付けて、鉤先の上方を通過できるようにしたものである。
【0024】
図8(b)、(c)は、実施形態と同様に、それぞれ、コイルばね12の先端部に下向きに開く鉤部材11b、11cを取り付け、可動フレーム4の前端側のブラケット19に鉤受け部材としての水平ピン20b、20cを取り付け、各水平ピン20b、20cを各鉤部材11b、11cの鉤先と干渉する高さ位置に配置するとともに、図8(b)は、鉤部材11bの鉤先の前後面に傾斜逃げ面21bを、図8(c)は、水平ピン20cの上側前後面に傾斜逃げ面21cを設けたものである。この2つの変形例では、可動フレーム4が後退して、各水平ピン20b、20cが各鉤部材11b、11cの鉤先に当たると、各傾斜逃げ面21b、21cの効果で各鉤部材11b、11cが僅かに上方へ逃げ、各水平ピン20b、20cが各鉤部材11b、11cの下に入り込む。
【0025】
【発明の効果】
以上のように、この発明の駐輪装置は、固定フレームの先端部に、先端部が自由状態の引張ばねを、その先端部が固定フレームの基端側へ向くように取り付け、この引張ばねの先端部と、可動フレームの前端部の回動中心よりも前端寄りの係止部位とに、係止部位の水平方向への移動に対しては係脱自在で、係止部位の上方向への移動に対してのみ、係止部位が引張ばねの先端部に係止される手段を設け、可動フレームの後端側が下方に回動されるときに、係止部位を引張ばねの先端部に係止して、引張ばねにより下方に引っ張るようにしたので、余分な部材を必要としないシンプルな構成で、可動フレームの後端側を上方に付勢することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle parking device for parking two-wheeled vehicles such as bicycles in two vertical stages.
[0002]
[Prior art]
There are various types of bicycle parking devices in which motorcycles are parked in the upper and lower stages, but a fixed frame that is horizontally supported at a predetermined height from the floor because of its relatively simple structure. And a movable frame that is movable back and forth along the fixed frame, the movable frame is retracted to the front end side of the fixed frame, and the rear end side is rotated downward with its front end as a center of rotation, thereby providing a two-wheeled vehicle. After that, the rear end side is rotated upward to a substantially horizontal position, and the movable frame rotated to the horizontal position is advanced to the base end side of the fixed frame to store the motorcycle. , Especially for bicycles.
[0003]
In this type of bicycle parking apparatus, the movable frame is initially connected to the fixed frame by a spring to bias the movable frame upward in order to apply an auxiliary force for rotating the movable frame carrying the bicycle upward. A device was devised.
[0004]
As described above, in the initial bicycle parking device in which the movable frame is connected to the fixed frame by a spring, when the movable frame is pulled out to the distal end side of the fixed frame, the spring force becomes a resistance and the drawer of the movable frame becomes heavy. Further, in order to solve this difficulty, a device has been devised in which a spring force acts only on the rotation of the movable frame.
[0005]
Examples of this type of bicycle parking device include those described in Japanese Patent Publication No. 2628675 and Japanese Patent Publication No. 2736513. In the former, as shown in FIG. 9, a rail member 52 is attached to a fixed frame 51 (base member), and a guide piece 54 attached to the front end of a movable frame 53 (mounting member) is freely movable to and from the rail member 52. At the rear end of the movable frame 53, a tension coil spring 56 provided with a hook-shaped locking body 55 at the distal end is attached toward the base end of the fixed frame 51, and fixed. A lock receiving body 57 to which the lock body 55 is locked is provided at the distal end of the frame 51.
[0006]
In this bicycle parking device, when the movable frame 53 is retracted to the distal end side of the fixed frame 51, the lock body 55 is locked by the lock receiving body 57, and the rear end of the movable frame 53 is pivoted around the guide piece 54 as a pivot. When the side is turned downward, the rear end side of the movable frame 53 is urged upward by the coil spring 56. That is, in this bicycle parking device, the spring force is applied only to the rotation of the movable frame 53 by connecting the coil spring 56 to the fixed frame 51 only when the movable frame 53 is rotated.
[0007]
In the latter, as shown in FIG. 10, a fixed frame 58 is formed of a grooved steel with a lip, and a free-running roller 61 fitted into a guide groove 60 of a movable frame 59 is attached to a tip end thereof. A swing frame 62 is pivotally attached to the front end side of the movable frame 59 by a pivot 63 so as to be able to swing back and forth. The swing end of the swing frame 62 is fitted between the lip of the fixed frame 58 and the bottom wall. A rolling roller 64 is attached, and the swinging tip is connected to a position rearward from the pivot 63 on the front end side of the movable frame 59 by a tension coil spring 65.
[0008]
Therefore, in this bicycle parking device, the movable frame 59 and the swing frame 62 are supported together by the rolling roller 64 that moves together at the front end side, and the idle roller 61 fixed at the rear end side to the fixed frame 58. When the movable frame 59 moves forward and backward along the fixed frame 58 and retreats to the front end side of the fixed frame 58 while being supported by the Then, the front end side of the rotation center is pulled downward by the coil spring 65, and the rear end side of the movable frame 59 is urged upward. That is, in this bicycle parking device, the spring force is applied only to the rotation of the movable frame 59 by connecting the coil spring 65 to the swing frame 62 that moves forward and backward together with the movable frame 59.
[0009]
[Problems to be solved by the invention]
The above-described conventional bicycle parking devices all apply a spring force only when the movable frame rotates, thereby facilitating the upward rotation of the movable frame on which the bicycle is mounted. Since the base end of the coil spring is attached to the rear end of the movable frame, a very long coil spring is required, and the long coil spring moves together with the movable frame, so that there is a problem that the coil spring is easily damaged. Further, the latter requires an extra swing frame for connecting the coil spring, and since this swing frame swings with respect to the movable frame, the swing is suppressed to guide the advance and retreat along the fixed frame. There is also a problem that the structure is complicated.
[0010]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a bicycle parking device which is excellent in maintainability, has a simple structure, and can provide a rotation assisting force of a movable frame.
[0011]
[Means for Solving the Problems]

The movable frame is retracted to the distal end side of the fixed frame, and the bicycle is placed by rotating the rear end side downward with the front end thereof as a center of rotation, and thereafter, the rear end side is positioned upward in a substantially horizontal position. The movable frame rotated to this horizontal position is advanced to the base end side of the fixed frame, and in a bicycle parking device for storing a motorcycle, the fixed frame has a free end at the front end. A tension spring is mounted such that its distal end is located below the movable frame and faces the proximal end of the fixed frame, and the distal end of the tension spring and the lower end of the front end of the movable frame are attached. From the rotation center It can be freely disengaged from the locking portion near the front end with respect to the horizontal movement of the locking portion, and the locking portion is only movable with respect to the upward movement of the locking portion. A means is provided for locking the distal end, and when the movable frame retreats toward the distal end of the fixed frame and the rear end pivots downward, the locking portion is engaged with the distal end of the tension spring. When the rear end of the movable frame is rotated downward, the front end of the movable frame is pulled downward by the tension spring from the center of rotation, and the rear end of the movable frame is rotated upward. It adopted a vigorous configuration.
[0012]
That is, a tension spring having a free end is attached to the front end of the fixed frame so that the front end faces the base end of the fixed frame. The locking part can be disengaged from the locking part closer to the front end than the moving center with respect to the horizontal movement of the locking part, and the locking part is pulled only for the upward movement of the locking part. Providing a means to be locked to the tip of the spring, and locking the locking portion to the tip of the tension spring and pulling down by the tension spring when the rear end of the movable frame is rotated downward. Thus, the rear end of the movable frame can be urged upward with a simple configuration that does not require an extra member.
[0013]
As means for locking and disengaging the horizontal movement of the locking portion and locking the locking portion to the tip of the tension spring only for upward movement of the locking portion, A hook member that opens downward is attached to the tip of the tension spring toward the locking portion, and a hook receiving member that is received by a hook bottom of the hook member is attached to the locking portion, and the hook receiving member is attached to the hook. A method of allowing the hook of the member to pass through in a horizontal direction, or attaching a hook member that opens upward to the locking portion toward the tip of the tension spring, and attaching the hook of the hook member to the tip of the tension spring. A method can be adopted in which a hook receiving member received on the bottom is attached, and the hook receiving member can pass through the hook of the hook member in the horizontal direction.
[0014]
As means for allowing the hook receiving member to pass through the hook of the hook member in the horizontal direction, a method of arranging the hook receiving member at a height position that horizontally passes through the hook of the hook member, An inclined flank is formed on at least one of the front and rear faces of the hook of the hook member or the front and rear faces of the hook receiving member on the side received by the hook bottom, and the hook of the hook member or the hook receiving member is formed. In the up-down direction to allow the hook receiving member to pass through the hook of the hook member. The inclined flank may be a curved surface.
