PROBLEM TO BE SOLVED: Many locking devices conscious of theft prevention have difficulty in portability. For example, in a bicycle without a basket such as a sports type bicycle, the locking device is hung on a handle and runs while swinging. I often see it. Such a portable method hinders the operation of the steering wheel, and in a sport-type bicycle in which the frame is thinned with aluminum or carbon and beautifully painted, it is difficult for the locking device that moves gently to damage the frame. However, if it takes time to fold and store when the locking device is not used, it will take time to use it and the locking will be neglected.
A portable locking device is held well by a rear wheel fender.
[Selection] FIG.

Description

本発明は、携帯式施錠装置を保持可能な自転車用フェンダーに関する。   The present invention relates to a bicycle fender capable of holding a portable locking device.

携帯式施錠装置においては、特許文献1のように被施錠物に略U字状棒を通してから略U字状棒の両端に略I字状棒を係止することで施錠するU字錠や、特許文献2のように被施錠物にワイヤーを通してからワイヤーがループ状になるように係止することで施錠するワイヤー錠がよく知られており、特許文献3のようにワイヤー錠を保持可能なブラケットのアイデアもよく知られている。   In the portable locking device, as in Patent Document 1, a U-shaped lock that locks by locking a substantially I-shaped rod on both ends of a substantially U-shaped rod after passing a substantially U-shaped rod through the locked object, A wire lock that locks by locking the wire in a loop shape after passing the wire through the object to be locked as in Patent Document 2, and a bracket that can hold the wire lock as in Patent Document 3 The idea of is well known.

施錠装置においては、頑丈そうな外観で、悪意ある第三者が被施錠物を盗難する意欲が無くなるようなものが望まれる。
また、門柱等につなぐように被施錠物を施錠して、被施錠物が容易に移動されないようにする為に、長いワイヤー等をもつ施錠装置が望まれる。
しかし、これらの盗難防止を意識した施錠装置は携帯性に難のあるものが多く、例えばスポーツタイプの自転車のようにカゴの無い自転車では、ハンドルに引っ掛けて頑丈そうな施錠装置をふらふらさせながら走行しているのをよく見かける。このような携帯方法はハンドル操作の妨げとなるし、フレームがアルミやカーボンで薄肉化され、美しい塗装が施されたスポーツタイプの自転車では、ふらふらと動く施錠装置がフレームを損傷することが心苦しい。だからといって、施錠装置を使用しないときに折りたたみ収納する手間がかかれば、いざ使用するときにも手間がかかり、ついつい施錠がおろそかになってしまう。
The locking device is desired to have a sturdy appearance and to eliminate the willingness of a malicious third party to steal the locked object.
In addition, a locking device having a long wire or the like is desired in order to lock the locked object so as to be connected to the gate pillar and the like so that the locked object is not easily moved.
However, many of these locking devices designed to prevent theft are difficult to carry. For example, a bicycle without a basket, such as a sports-type bicycle, can be hung on the steering wheel while driving a locking device that seems to be sturdy. I often see it. Such a portable method hinders the operation of the steering wheel, and in a sport-type bicycle in which the frame is thinned with aluminum or carbon and beautifully painted, it is difficult for the locking device that moves gently to damage the frame. However, if it takes time to fold and store when the locking device is not used, it will take time to use it, and locking will be neglected.

本発明の実施形態図等を用いて以下に説明するが、これは本発明の内容をより把握しやすいようにする為で、添付の特許請求の範囲を縮小するものではない。   Embodiments of the present invention will be described below with reference to the drawings and the like, but this is intended to make the contents of the present invention easier to understand, and does not reduce the scope of the appended claims.

はじめに、図1及び図2を用いてループ状の携帯式施錠装置1の代表的な2例について簡単に説明する。
まず、図1はワイヤー錠であり、屈曲可能な線状部3の一端は錠本体4に、他端は係止部6に接続されている。また、錠本体4の側面から内部に貫通された穴5から係止部6を挿入することで、錠本体4の係止片に係止部6は係止される。ここで鍵穴8から鍵を挿入し回転させることで係止片による係止は外れ、係止部6を引き抜くことが可能となる。
また、図2はU字錠であり、屈曲不能な略U字状の線状部3の一端には係止部6、他端には係止部10が設けられている。また、錠本体4の側面から内部に貫通された穴5及び11からそれぞれ係止部6及び10を挿入し、鍵穴8から鍵を挿入し回転させることで錠本体4の係止片に係止部6及び10は係止される。
First, two typical examples of the loop-shaped portable locking device 1 will be briefly described with reference to FIGS. 1 and 2.
First, FIG. 1 shows a wire lock, in which one end of a bendable linear portion 3 is connected to a lock body 4 and the other end is connected to a locking portion 6. Further, the locking portion 6 is locked to the locking piece of the lock body 4 by inserting the locking portion 6 through the hole 5 penetrating from the side surface of the lock body 4 to the inside. Here, by inserting and rotating the key from the key hole 8, the locking by the locking piece is released, and the locking portion 6 can be pulled out.
FIG. 2 shows a U-shaped lock, in which a substantially U-shaped linear portion 3 that cannot be bent is provided with a locking portion 6 at one end and a locking portion 10 at the other end. In addition, the locking portions 6 and 10 are inserted through the holes 5 and 11 penetrating from the side of the lock body 4 to the inside, respectively, and the key is inserted from the key hole 8 and rotated to be locked to the locking piece of the lock body 4. Parts 6 and 10 are locked.

次に、図3、5、9のいずれかを用いて自転車50の代表的な例について簡単に説明する。

また、フロントフォーク53はハンドルステム52及びハンドル51に接続され、前輪54はフロントフォーク53先端部で回転可能に支持されている。また、後輪61はシートステイ59及びチェーンステイ60の接続部で回転中心軸線62を中心に回転可能に支持されている。
また、シートチューブ58の開口端にシートポスト64が挿入されてから固定されており、シートポスト64の先端にはサドル63が固定されている。
また、後輪61用のフェンダー20の一端部はシートチューブ58、シートステイ59、チェーンステイ60、サドル63、シートポスト64のいずれかに固定されるのが一般的である。
Next, a typical example of the bicycle 50 will be briefly described with reference to any of FIGS.
First, the frame of the bicycle 50 includes a head tube 55, a front fork 53, a top tube 56, a down tube 57, a seat tube 58, a seat stay 59 and a chain stay 60.
The front fork 53 is connected to the handle stem 52 and the handle 51, and the front wheel 54 is rotatably supported at the front end of the front fork 53. Further, the rear wheel 61 is supported at the connecting portion of the seat stay 59 and the chain stay 60 so as to be rotatable about the rotation center axis 62.
The seat post 64 is fixed after being inserted into the opening end of the seat tube 58, and the saddle 63 is fixed to the tip of the seat post 64.
Further, one end of the fender 20 for the rear wheel 61 is generally fixed to any of the seat tube 58, the seat stay 59, the chain stay 60, the saddle 63, and the seat post 64.
