ある。That is, according to the present invention, in a bicycle having a pair of left and right handles and pedals, a portion of the handle that is folded is connected to a support shaft (4) that is foldably connected inward by a bolt (9) as shown in FIG. ) Is formed by a straight portion (3b) and a straight portion (2b) into which the spindle is inserted, and each straight portion is formed into a male type and a female type as shown in FIG.
As shown in FIG. 4, when the two straight parts are connected and fixed by a stopper sleeve (6) having a protrusion (6a) on the inner surface that fixes the handle so that it cannot swivel inward, as shown in FIG. The child is connected without a gap, and when the stopper sleeve is moved upward to release the fixation of the straight portion, as shown in FIG. A bicycle having a handle and / or a pedal that allows the inside of the pedal to be turned by the same mechanism as the handle, which is formed so as to be able to turn.
（実施例） 次に本発明を図面に図解的に示す実施例により更に詳し
く説明する。(Embodiment) Next, the present invention will be described in more detail with reference to an embodiment schematically shown in the drawings.
本発明の自転車は本発明の目的を達成する上で、ハンド
ルのみを内側に折り畳めるようにしてもよいし、更にペ
ダルも内側に折り畳めるようにしてもよい。In the bicycle of the present invention, in order to achieve the object of the present invention, only the handle may be folded inward or the pedal may be folded inward.
先ず、ハンドルを折り畳む例を第１図乃至第７図を参照
して説明する。First, an example of folding the handle will be described with reference to FIGS. 1 to 7.
図において、（１）は丸パイプからなるバーハンドルを
示し、該バーハンドル（１）はステアリングシャフトに
取り付けられる取付部（2a）を有する内側部分（２）
と、ハンドルグリップ（3a）を有する左右一対の外側部
分（３）（３）とで構成されるものとする。左右の構造
は対称的であるので、右側部分を代表して説明する。In the figure, (1) shows a bar handle made of a round pipe, and the bar handle (1) has an inner part (2) having a mounting part (2a) mounted on a steering shaft.
And a pair of left and right outer portions (3) and (3) having a handle grip (3a). Since the left and right structures are symmetrical, the right part will be described as a representative.
右の外側部分（３）の略下方にのびる直状部（3b）に支
軸（４）を突設し、該直状部（3b）に略四分円形の係止
片（５）を突設すると共に、該直状部（3b）に、ストッ
パースリーブ（６）の内周の突子（6a）を挿入可能な凹
欠（７）を該係止片（５）の側面（5a）に連続するよう
に形成した。A support shaft (4) is provided so as to project on a straight portion (3b) extending substantially below the right outer portion (3), and a substantially quadrant circular locking piece (5) is projected on the straight portion (3b). At the same time, the recess (7) into which the protrusion (6a) of the inner circumference of the stopper sleeve (6) can be inserted is provided on the side surface (5a) of the locking piece (5) in the straight portion (3b). It was formed so as to be continuous.
そして、前記内側部分（２）の右側の略上方にのびる直
状部（2b）に略半円形の突片（８）を形成し、該内側部
分（２）の直状部（2b）を前記シャフト（４）に挿入
し、内側部分（２）の直状部（2b）の下端から締結ボル
ト（９）を螺入して内側部分（２）に対し外側部分
（３）が旋回し得るように連結した。Then, a substantially semicircular projecting piece (8) is formed on the straight portion (2b) extending to the right side of the inner portion (2), and the straight portion (2b) of the inner portion (2) is Insert the shaft (4) and screw the fastening bolt (9) from the lower end of the straight part (2b) of the inner part (2) so that the outer part (3) can turn with respect to the inner part (2). Connected to.
更に、締結ボルト（９）の螺入に先立って、外側部分
（３）の直状部（3b）に前記ストッパースリーブ（６）
を凹欠（７）に位相を合せて挿入し、該直状部（3b）に
固定したスプリングストッパー（10）と該スリーブ
（６）との間にスプリング（11）を介設して、ストッパ
ースリーブ（６）を、突子（6a）が前記突片（８）の側
面（8a）と係止片（５）の側面（5a）との間に介入され
る係合側（図面で下方）に押し付けた（第４図の状
態）。Further, before the fastening bolt (9) is screwed in, the stopper sleeve (6) is attached to the straight portion (3b) of the outer portion (3).
The spring (11) is inserted between the spring stopper (10) fixed to the straight portion (3b) and the sleeve (6) by inserting the spring into the recess (7) in phase with each other, and the stopper is provided. The sleeve (6) has an engagement side (downward in the drawing) in which the projection (6a) is interposed between the side surface (8a) of the projection piece (8) and the side surface (5a) of the locking piece (5). It was pressed against (state of FIG. 4).
かくて前記突子（6a）の係合状態では、係止片（５）の
側面（5a）の突子（6a）を介しての突片（８）の側面
（8a）側への当接により、内側部分（２）に対する外側
部分（３）の時計方向への旋回が阻止され、又、係止片
（５）の他方の側面（5b）の突片（８）の他方の側面
（8b）への当接により、内側部分（２）に対する反時計
方向への旋回が阻止され、結局外側部分（３）が旋回不
能となり通常状態にロックされる（第４図示の状態）。Thus, in the engaged state of the protrusion (6a), the side surface (5a) of the locking piece (5) comes into contact with the side surface (8a) side of the protrusion piece (8) via the protrusion (6a). This prevents the outer part (3) from turning clockwise relative to the inner part (2), and the other side surface (8b) of the protruding piece (8) of the other side surface (5b) of the locking piece (5). ), The counterclockwise turning with respect to the inner part (2) is blocked, and the outer part (3) is eventually unable to turn and is locked in the normal state (state shown in FIG. 4).
又、ストッパースリーブ（６）をスプリング（11）に抗
して解除側（上側）に移動すれば、突片（８）の側面
（8a）部分に突子（6a）が存しないため（第５図示の状
態）、内側部分（２）に対し外側部分（３）を係合子
（５）の側面（5a）が突片（８）の側面（8a）に当接す
る迄時計方向に従って内側に旋回でき折りたたみ状態に
なる。Further, if the stopper sleeve (6) is moved to the release side (upper side) against the spring (11), there is no protrusion (6a) on the side surface (8a) of the protruding piece (8) (the fifth position). (State shown), the outer part (3) can be swung inward in a clockwise direction until the side surface (5a) of the engaging element (5) contacts the side surface (8a) of the projecting piece (8) with respect to the inner part (2). It will be in a folded state.
折り畳んだ後は、ストッパースリーブ（６）はスプリン
グ（11）に押されて突子（6a）の下面が突片（８）の上
面に当接し解除状態に保持され、この状態から外側部分
（３）を反時計方向に従って外側に旋回すれば、突子
（6a）が突片（８）の上面から外れたところでストッパ
ースリーブ（６）が係合側に移動されてワンタッチで通
常状態になる。After folding, the stopper sleeve (6) is pushed by the spring (11) and the lower surface of the protrusion (6a) abuts the upper surface of the protruding piece (8) and is held in the released state. 2) is swung outward in the counterclockwise direction, the stopper sleeve (6) is moved to the engagement side when the protrusion (6a) is disengaged from the upper surface of the protrusion (8), and the normal state is obtained with one touch.
この場合、少なくとも係止片（５）の側面（5a）を第７
図に示す如く斜面に形成しておくことで該斜面の楔作用
により内側部分（2b）に対する外側部分（3b）のガタつ
きを無くすことができ有利である。In this case, at least the side surface (5a) of the locking piece (5) should be the seventh
As shown in the figure, it is advantageous that the slanted surface is formed so that the slanted surface can eliminate the rattling of the outer portion (3b) with respect to the inner portion (2b) due to the wedge action.
本発明では上記の如くハンドルを折り畳むのみならず、
ペダルも同一機構によって内側に折り畳むことができ

4）を旋回自在に連結した。In the present invention, not only is the handle folded as described above,
The pedal can also be folded inward by the same mechanism. An example of this will be described with reference to FIGS. 8 and 9.
In the figure, (12) indicates a pedal arm, and the pedal arm (1
A sleeve (2) is provided with an engaging piece (5 ') and a support shaft (4') protruding from the end of 2) and a pedal shaft (14) supporting the pedal (13). A protrusion (8 ') similar to the above is formed on 15), the sleeve (15) is inserted into the support shaft (4'), and a nut (16) is attached to the threaded portion at the lower end of the support shaft (4 '). ) Is screwed onto the pedal arm (12) and the pedal shaft (1
4) is connected so that it can rotate freely.
