Description
【考案の詳細な説明】 （考案の技術分野） 本考案は、自転車のダウンヒル型ハンドルの先端部を固
定的に連結するための連結具に関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a connector for fixedly connecting a tip end portion of a downhill type handle of a bicycle.
（考案の技術的背景） 最近では自転車用のハンドルとして、ダウンヒル型ハン
ドルが用いられるようにようになってきている。即ち、
このダウンヒル型ハンドル１は、第９図に示すように、
ハンドルラグ２に貫挿されて固定されている直線部1a
と、斜め下方に伸長し、中央が湾曲している握部1bと、
走行方向の前方に略平行に突出している先端部1cとから
成る。(Technical background of the invention) Recently, a downhill type handle has come to be used as a handle for a bicycle. That is,
This downhill type handle 1 is, as shown in FIG.
Straight part 1a inserted through and fixed to the handle lug 2
And a grip 1b that extends diagonally downward and has a curved center,
And a tip portion 1c protruding substantially parallel to the front in the traveling direction.
かかる形状のダウンヒル型ハンドル１において、サイク
リスト（cyclist）は、通常、手により握部1bを握って
自転車を走行させる。そして、下り坂（downhill）等に
おいては風の抵抗を最少にすべく肘（腕）を直線部1aに
載せ、かつ手により先端部1cを握って自転車を走行させ
る。In the downhill type steering wheel 1 having such a shape, a cyclist usually holds the grip portion 1b with his / her hand and runs the bicycle. Then, on a downhill or the like, the elbow (arm) is placed on the linear portion 1a to minimize the wind resistance, and the tip portion 1c is gripped by the hand to run the bicycle.
このようなダウンヒル型ハンドル１は、肘（腕）を直線
部1aに載せることで腕に不要な力を入れず、楽な姿勢で
自転車を走行させ得るので、最近ではトライアスロン用
の自転車に多用されている。Such a downhill type handle 1 can be used in a comfortable posture without putting unnecessary force on the arm by placing the elbow (arm) on the straight line portion 1a, so these days are often used for triathlon bicycles. ing.
（背景技術の問題点） しかし、ダウンヒル型ハンドル１は従来のハンドルに比
べて長さ寸法が大きいので、先端部1c,1cに力が加わっ
た場合当該先端部1c,1cが上下、左右にランダムに動い
てしまう。このため、サイクリストの重心が横方向に移
動する等により自転車の走行状態が不安定になり、非常
に危険であった。(Problems of background art) However, since the downhill type handle 1 has a larger length dimension than the conventional handle, when a force is applied to the tip portions 1c, 1c, the tip portions 1c, 1c are randomly moved vertically and horizontally. Move to. Therefore, the traveling state of the bicycle becomes unstable due to the center of gravity of the cyclist moving laterally, which is very dangerous.
（考案の目的） 本考案の目的は、ダウンヒル型ハンドルの先端部がラン
ダムに動くのを防止することができる連結具を提供する
ことにある。(Object of the Invention) An object of the present invention is to provide a connector that can prevent the distal end portion of the downhill type handle from moving randomly.
（考案の概要） 本考案は、ダウンヒル型ハンドルの両先端部を連結する
連結具であって、前記両先端部に着脱可能に固定される
一対の固定部と、これら固定部を一体的に連結する連結
部とから成ることを特徴としている。(Summary of the Invention) The present invention is a connector for connecting both ends of a downhill type handle, wherein a pair of fixing parts detachably fixed to the both ends and the fixing parts are integrally connected. It is characterized in that it comprises a connecting portion.
（考案の実施例） 以下、本考案の実施例を図面を参照して詳細に説明す
る。Embodiments of the Invention Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
本考案に係る連結具10は、第１図（Ａ），（Ｂ）に示す
ように、固定部11,11を備えている。これらの固定部11

されている。この連結部12の中央は両貫通穴11a,11aに
連通している連通溝12aが形成されて二分され、又連結
部12の各貫通穴11a近傍には該貫通穴11aに対して直交す
る方向に貫通するねじ穴12bが形成されている。As shown in FIGS. 1A and 1B, the connector 10 according to the present invention includes fixing parts 11, 11. These fixed parts 11
Has a circular through hole 11a and is integrally connected by a connecting portion 12. A communication groove 12a communicating with both through holes 11a, 11a is formed at the center of the connecting portion 12 and is divided into two, and in the vicinity of each through hole 11a of the connecting portion 12, a direction orthogonal to the through hole 11a is formed. A screw hole 12b penetrating therethrough is formed.
一方、ダウンヒル型ハンドル13は、第２図に示すよう

とから成る。On the other hand, the downhill type handle 13 is, as shown in FIG. 2, a straight part which is inserted and fixed in the handle lug 2.
13a and a grip 13b that extends obliquely downward and has a curved center
And a tip portion 13c protruding substantially parallel to the front in the traveling direction.
It consists of and.
次に、本考案の連結具10の使用態様を説明する。Next, a usage mode of the connector 10 of the present invention will be described.
即ち、第１図及び第２図に示すように、連結具10の各固
定部11を貫通穴11aを介してダウンヒル型ハンドル13の
両先端部13cに嵌合し、ねじ穴12bにねじ部材14を螺入す

連通溝12aの間隔を小さくする方向に接近するので、固
定部11が貫通穴11aの径を小さくするように変形する。
従って、固定部11,11にて両先端部13cを締め付けて連結
具10を固定的に取付け、この連結具10により両先端部13
cを連結することができる。That is, as shown in FIGS. 1 and 2, each fixing portion 11 of the connecting tool 10 is fitted into both end portions 13c of the downhill type handle 13 through the through hole 11a, and the screw member 14 is inserted into the screw hole 12b. Screw in. Since the connecting portion 12 bisected by the screwing of the screw member 14 approaches in the direction of reducing the distance between the communication grooves 12a, the fixing portion 11 is deformed so as to reduce the diameter of the through hole 11a.
Therefore, the connecting parts 10 are fixedly attached by tightening the both end parts 13c with the fixing parts 11 and 11, and the both end parts 13c are fixed by the connecting parts 10.
c can be concatenated.
さて、通常の走行時には、第３図に示すように、ダウン
ヒル型ハンドル13の握部13bを手により握る。これに対
して、下り坂等においては、第４図に示すように、肘
（腕）を直線部13aに載せ、かつ各先端部13cを手により
握る。この場合両先端部13cは連結具10にて相互に連結
されているので、手により力が加わっても殆ど動くこと
がない。従って、自転車を安全に走行させることができ
る。Now, during normal traveling, as shown in FIG. 3, the grip portion 13b of the downhill type handle 13 is gripped by the hand. On the other hand, on a downhill or the like, as shown in FIG. 4, the elbow (arm) is placed on the linear portion 13a and each tip portion 13c is grasped by the hand. In this case, since the two tip portions 13c are connected to each other by the connecting tool 10, they hardly move even if a force is applied by hand. Therefore, the bicycle can be safely driven.

先端部13cを連結することができる。In the connector 10 having the above configuration, the rubber body 16 and the nut member 18 are inserted into the tip portion 13c of the downhill type handle 13 and the screw member 17 is turned. In this case, since the nut member 18 is in contact with the rubber body 16, even if the screw member 17 is rotated, it does not rotate due to frictional force, and the rubber body 16 is pressed. Therefore, the rubber body 16 is crushed and expands in diameter, and presses the inner peripheral surface of the tip portion 13c, so that the connector 10 can be fixedly attached to the tip portion 13c, and both tip portions 13c can be connected.
