(57) [Summary] [Object] The present invention relates to a connecting duct having a degree of freedom for rotating a joint between a female duct and a male duct or sliding the duct in an axial direction. However, it is possible to respond to swinging even when there is variation in the car body,
In that case, the influence of ventilation resistance does not appear, air leakage is eliminated, and variations in the vehicle body length direction can be dealt with by the slide duct. An expanded arc-shaped flange is formed on a female duct end part, and an expanded arc-shaped flange is formed on the male side duct end part so as to be inwardly rotatable with respect to the arc-shaped flange. A connection duct with a degree of freedom, characterized in that a slide duct is slidably fitted on one side.
Description
【０００１】[0001]
本考案は、雌側ダクトと雄側ダクトの接合部を回動したり、ダクトを摺動した りできるような自由度を持たせた接続ダクトに関する。 The present invention relates to a connecting duct having a degree of freedom such that a joint between a female duct and a male duct can be rotated or slid.
【０００２】[0002]
従来、雌側ダクトと雄側ダクトを接合する際、図５に示す如く、雌側ダクト２ ０のスリ−ブ２１内に雄側ダクト２２を嵌合するようにするか、図６に示す如く 、両ダクト１０，１１のフランジ１２，１３をパッキング１４を介して突き合わ せるかしていた。 Conventionally, when the female duct and the male duct are joined, as shown in FIG. 5, the male duct 22 is fitted into the sleeve 21 of the female duct 20 or as shown in FIG. The flanges 12 and 13 of both ducts 10 and 11 are butted against each other via the packing 14.
【０００３】[0003]
上記従来技術にあっては、両ダクトの位置ズレ、芯ズレ及び車輌バラツキ等が あると、嵌合部をカットしてテ−ピングを行うか、ハンドワ−クにて部分加工が 必要となり、工数費用がかゝり、嵌合部が突き合せ構造の場合は上記同様の不具 合が発生した場合はエア−洩れを生ずるという問題点があった。 In the above-mentioned conventional technology, if there is misalignment of both ducts, misalignment of the ducts, variations in the vehicle, etc., it is necessary to cut the fitting part and perform taping, or to carry out partial machining with a handwork. There is a problem that the cost is high, and if the fitting portion has a butt structure, if the same defect as described above occurs, air leakage occurs.
【０００４】[0004]
本考案は上記問題点を解決することを目的とし、雌側ダクト端末部に拡開した 円弧状フランジを形成し、雄側ダクト端末部に前記円弧状フランジに内接回動し 得る拡開した円弧状フランジを形成し、上記ダクトの少なくとも一方にスライド ダクトを摺動自在に嵌合させたことを特徴とする。 The present invention aims to solve the above-mentioned problems, and forms an expanded arc-shaped flange on the female duct end, and expands the male duct end so that it can be inscribed in the arc-shaped flange. An arcuate flange is formed, and a slide duct is slidably fitted to at least one of the ducts.
【０００５】[0005]
次に図１乃至図４に示した本考案の一実施例について詳細に説明する。１は雌 側ダクトで端末部に拡開した円弧状フランジ２を一体に形成している。３は雄側 ダクトで端末に前記円弧状フランジ２に内接回動し得る拡開した円弧状フランジ ４を一体形成してある。円弧状フランジ２の半径をＲ1とし円弧状フランジ４の 半径をＲ2とするとＲ1＞Ｒ2で、図３の如く雌側ダクト１と雄側ダクト３を首振 り回動した時、円弧状フランジ４は円弧状フランジ２に一部が内接し乍ら角度Ｃ 回動できる。Next, an embodiment of the present invention shown in FIGS. 1 to 4 will be described in detail. Reference numeral 1 denotes a female duct integrally formed with an arcuate flange 2 which is widened to the end. Reference numeral 3 denotes a male duct, which is integrally formed with a widened arc-shaped flange 4 capable of inwardly rotating on the arc-shaped flange 2 at the end. Assuming that the radius of the arc-shaped flange 2 is R 1 and the radius of the arc-shaped flange 4 is R 2 , R 1 > R 2 , and when the female duct 1 and the male duct 3 are swung as shown in FIG. The arc-shaped flange 4 is partially inscribed in the arc-shaped flange 2 and can rotate by an angle C.
【０００６】 又、雌側ダクト１の内径Ａに対して雄側ダクト３の開口Ｂを大きくしてある。 従って、両ダクト１，３の軸芯がズレを起したり、両ダクトが首振り回動しても 通風路の一部がふさがれることはない。又、雄側ダクト３にスライドダクト５を 摺動自在に嵌合し、一部にストッパ−凸部６を設け、雄側ダクト３のストッパ− 凹部７により距離Ｄの位置調整を行うことができる。８，９は雄側ダクト３、ス ライドダクト５のブラケットで、スライドにより伸縮した最終位置を固定するよ うになっている。Further, the opening B of the male duct 3 is larger than the inner diameter A of the female duct 1. Therefore, even if the axial centers of both ducts 1 and 3 are displaced or both ducts swing and rotate, part of the ventilation passage is not blocked. Further, the slide duct 5 is slidably fitted to the male duct 3 and a stopper-convex portion 6 is provided in a part thereof, and the position of the distance D can be adjusted by the stopper-concave portion 7 of the male duct 3. . Reference numerals 8 and 9 denote brackets for the male duct 3 and the slide duct 5, which are fixed by sliding to extend and retract the final position.
【０００７】[0007]
本考案によると、雌側ダクト端末部に拡開した円弧状フランジを形成し、雄側 ダクト端末部に前記円弧状フランジに内接回動し得る拡開した円弧状フランジを 形成し、上記ダクトの少なくとも一方にスライドダクトを摺動自在に嵌合させて あるので、下記の効果を有する。 １．車体のバラツキ発生に於ても首振り対応が可能。 ２．首振り状態に於て雌側ダクト通風路Ａに対し、雄側ダクト開口Ｂを大きくし た ことにより、通気抵抗の影響がでない。 ３．接合フランジのバラツキによる首振り時に於ても常に円弧が接しているので エア−洩れ防止となる。 ４．車体の長手方向のバラツキに於てもスライドダクトにて対応が可能。 ５．上記１〜４より試作時適用ダクトとして効果を有する。 According to the present invention, the female side duct end portion is formed with an expanded circular arc flange, and the male side duct end portion is formed with an expanded circular arc flange capable of inwardly rotating with the circular arc flange. Since the slide duct is slidably fitted to at least one of the above, the following effects are obtained. 1. It is also possible to respond to swinging even when vehicle body variations occur. 2. In the swinging state, by increasing the male duct opening B with respect to the female duct ventilation passage A, there is no influence of ventilation resistance. 3. Since the arcs are always in contact with each other even when swinging due to variations in the joint flange, air leakage is prevented. 4. Sliding ducts can be used to deal with variations in the longitudinal direction of the vehicle body. 5. From the above 1 to 4, it has an effect as a duct applied at the time of trial manufacture.
