本考案は自転車用ブレーキ等に用いられているいわゆる
ボーデン機構におけるインナーワイヤの締付固着具の改
良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of an inner wire tightening fixture in a so-called Bowden mechanism used in bicycle brakes and the like.

確実に固定できなかった。The wire clamping part of the wire tightening screw, which is conventionally used to fasten and fix the inner wire of the brake wire etc. to the wire fixing member such as the brake arm, and the wire clamping part of the wire fixing member opposite to the wire clamping part are Since both were flat, the wire could not be securely fixed unless it was tightened quite strongly.

。As a result, the wire at the outermost end of the gripping part of the wire tightening screw against the inner wire is extremely bent, which makes it difficult to change the tightening position of the inner wire, and the nut cannot be tightened too much. There were drawbacks such as a part of the inner wire breaking, which significantly shortened the life of the wire.

る。The present invention was devised in order to eliminate the above-mentioned drawbacks, and the wire clamping parts of both the wire fixing member and the wire tightening screw that clamp the wire are made into conical shapes so that the wire can be bent and clamped. This makes it possible to securely fix the wire even with a weaker tightening force than conventional methods, and also disperses the shear core force that sometimes concentrates locally when tightening the wire, increasing the durability of the wire without reducing the clamping force of the wire. The purpose is to improve safety and safety.
以下図面について本考案の実施例を説明する。Embodiments of the present invention will be described below with reference to the drawings.

じ挿通孔である。In the figure, 1 and 2 are the brake arms of the caliper brake, 3 is the pivot bolt, 4 is the spring, 5 is the brake shoe, 6 is the outer wire fixed to one brake arm 2 via the wire adjuster 7, and 8 is the inner wire. The wire 9 is a wire tightening screw for fixing this inner wire 8 to the other brake arm (wire fixing member) 1, and 9a is a wire insertion provided through the neck of the wire tightening screw 9 in the diametrical direction. 10 is a flat washer, 11 is a nut, and 1a is a wire tightening screw insertion hole provided in the wire fixing member 1.

締付ねじ９のワイヤ挾持部９ｂを截頭円錐形にする。In the present invention, a countersunk-like conical recess 1b is provided on one side of the wire tightening screw insertion hole 1a provided in the wire fixing member 1, and the wire of the wire tightening screw 9 facing the conical recess 1b is provided. The clamping portion 9b is shaped like a truncated cone.
また、ワイヤ固定部材１の円錐凹陥部１ｂの錐角αより
もワイヤ締付ねじ９のワイヤ挾持部９ｂの錐角βを若干
小さくする。Further, the cone angle β of the wire clamping portion 9b of the wire tightening screw 9 is made slightly smaller than the cone angle α of the conical concave portion 1b of the wire fixing member 1.
次に上述のように構成した本考案ワイヤ固着具の作用を
説明する。Next, the operation of the wire fixing device of the present invention constructed as described above will be explained.
ワイヤ締付ねじ９のワイヤ挿通孔９ａにインナーワイヤ
８を挿通し、このワイヤ締付ねじ９をワイヤ固定部材で
あるブレーキアーム１の孔１ａに挿入し、平座金１０、
ナツト１１により第２図に示すように締結する。Insert the inner wire 8 into the wire insertion hole 9a of the wire tightening screw 9, insert the wire tightening screw 9 into the hole 1a of the brake arm 1, which is the wire fixing member, and then insert the flat washer 10,
Fasten with nuts 11 as shown in FIG.
このようにするとインナーワイヤ８はブレーキアーム１
の皿もみ状の円錐凹陥部１ｂとワイヤ締付ねじ９の截頭
円錐形状のワイヤ挟持部９ｂとの間にくの字状に締結さ
れる。In this way, the inner wire 8 is connected to the brake arm 1.
It is fastened in a dogleg shape between the countersunk-shaped conical concave portion 1b and the frusto-conical wire clamping portion 9b of the wire tightening screw 9.
すなわちこの場合インナーワイヤ８は屈曲した状態で挾
持されるため、従来のようにインナーワイヤを直線状態
で挾持した場合よりもワイヤの固定が確実になる。That is, in this case, since the inner wire 8 is held in a bent state, the wire is more securely fixed than when the inner wire is held in a straight state as in the conventional case.
したがって本考案のワイヤ固着具によれば、従来のもの
より弱い締付力でワイヤを確実に固定できる。Therefore, according to the wire fixing device of the present invention, the wire can be securely fixed with a weaker tightening force than the conventional device.
このため本考案によればワイヤに作用するせん断応力を
分散させるとともに、充分な挟持力を得ることができる
。Therefore, according to the present invention, the shear stress acting on the wire can be dispersed, and sufficient clamping force can be obtained.
更にブレーキアームの皿もみ状の円錐凹陥部１ｂの錐角

止すると共に、インナーワイヤ８の耐久力をより一層向
上させる効果が得られる。Furthermore, since the cone angle β of the frustoconical wire clamping portion 9b of the wire tightening screw 9 is made slightly smaller than the cone angle α of the countersunk conical recess 1b of the brake arm, bending stress is repeatedly applied by braking. Since the fastening force near the outer end of the clamping part of the inner wire 8 that receives the inner wire 8 is slightly weaker, this has the effect of preventing the inner wire 8 from being cut due to brake operation and further improving the durability of the inner wire 8. is obtained.
このように本考案によれば、インナーワイヤ８の締結時

ともに、ブレーキ操作に起因するインナーワイヤ８の切
断を防止することができるという効果が得られる。As described above, according to the present invention, the durability of the inner wire 8 is improved by dispersing the shear stress when the inner wire 8 is fastened and obtaining sufficient clamping force, and the inner wire 8 can be prevented from being cut.
