【考案の詳細な説明】
この考案は、特にブロー成形されたプラスチック製の通
風ダクトにおいて、該通風ダクトの途中に開口部を設け
、この開口部にスライドドア又はグリル等の部品を設け
るための組付構造に関し、例えば自動車用空気調和装置
の膝元吹出口として利用されるものである。[Detailed description of the invention] This invention is a blow-molded plastic ventilation duct, in which an opening is provided in the middle of the ventilation duct, and an assembly for installing parts such as a sliding door or a grill in this opening. Regarding the attached structure, it is used, for example, as a knee outlet of an air conditioner for an automobile.
自動車用空気調和装置における膝元吹出口は、中央吹出
口から左右吹出口に至る通風ダクトの途中に設けられて
いる。The knee air outlet in an automobile air conditioner is provided in the middle of a ventilation duct that extends from the center air outlet to the left and right air outlets.
この通風ダクトは、例えばブロー成形されたプラスチッ
ク製のもので、該通風ダクトに開口部が設けられ、この
開口部に取り付けられた部品組付部材にスライドドア、
グリル等の部品が組み付けられて膝元吹出口が構成され
ている。This ventilation duct is made of blow-molded plastic, for example, and has an opening provided in the ventilation duct, and a sliding door attached to the component assembly member attached to the opening.
The knee air outlet is constructed by assembling parts such as a grill.
前記部品組付部材は、通風ダクトの開口部に対応した窓
が形成され、この部品組付部材にスライドドアを組み付
けた場合には、スライドドアを摺動させることによって
部品組付部材の窓の開度が調整されて膝元吹出口から吹
き出される空気の制御が行なわれる。The component assembly member is formed with a window corresponding to the opening of the ventilation duct, and when a sliding door is assembled to this component assembly member, the window of the component assembly member is opened by sliding the sliding door. The opening degree is adjusted to control the air blown out from the knee outlet.
しかしながら、従来のこの種の部品組付構造にあっては
、部品組付部材が通風ダクトの開口部の周囲の壁にリベ
ット止めされるか、又は部品組付部材に設けられた嵌合
爪が開口部の周囲の壁に嵌合して取り付けられている。However, in this type of conventional component assembly structure, the component assembly member is riveted to the wall around the opening of the ventilation duct, or the fitting claw provided on the component assembly member is fixed to the wall around the opening of the ventilation duct. It is fitted and attached to the wall around the opening.
そのため、前者のリベット止め方式にあっては、上記の
自動車用空気調和装置の膝元吹出口のように、開口部が
通風ダクトの両端から離れており、且つ開口部の開口面
積が小さい場合には、通風ダクトの内側にかしめ器具等
を挿入することが不可能であるから、リベットをかしめ
る作業が極めて困難であるという欠点を有する。Therefore, in the former riveting method, when the opening is far from both ends of the ventilation duct and the opening area of the opening is small, such as the knee outlet of the above-mentioned automobile air conditioner, However, since it is impossible to insert a caulking tool or the like inside the ventilation duct, there is a drawback that the work of caulking the rivet is extremely difficult.
また、後者の嵌合爪による方式にあっては、通風ダクト
がブロー成形製であれば通風ダクトの開口部の周囲の壁
の肉厚が一定していないのでJ例えば4個の嵌合爪の立
上り高さとそれに対応する壁の厚さをすべて一致させる
ことが不可能であり、そのため部品組付部材にガタを生
じるという欠点を有する。In addition, in the latter method using fitting claws, if the ventilation duct is made of blow molding, the thickness of the wall around the opening of the ventilation duct is not constant. It is impossible to match all the rising heights and the corresponding wall thicknesses, which has the disadvantage of causing looseness in the component assembly members.
そこで、この考案は、上記の欠点を解消するため、部品
組付部材の窓を挾んで部品組付部材の枠の一方を開口部
の周囲の壁に嵌込固定すると共に、前記枠の他方側で該
粋に設けられた腕を用いて開口部の周囲の壁を挾み付け
て固定するようにして、小さい開口部へも容易に部品組
付部材を取り付けることかできると共に、ガタを生じな
い部品組付構造を提供しようとするものである。Therefore, in order to eliminate the above-mentioned drawbacks, this invention has been developed by fitting and fixing one of the frames of the component assembling member into the wall surrounding the opening by sandwiching the window of the component assembling member, and fixing the other frame of the component assembling member to the wall surrounding the opening. By using the smartly provided arms to clamp and fix the wall around the opening, it is possible to easily attach the parts assembly member even to a small opening, and there is no play. The purpose is to provide a parts assembly structure.
以下、この考案の実施例を図面により説明する。Examples of this invention will be described below with reference to the drawings.

出するように形成されている。This opening 2 has a notch 2b formed by cutting out a part of the wall around one side of a rectangular window 2a in a semicircular shape, and a notch 2b formed around the entire circumference of the opening 2. The surface 2c is formed to protrude outward.
このような開口部2の製作は、第5図に示すように、通
風ダクト1のブロー成形時に該通風ダクト1の一部を外
側に突出させた突出部5を2点鎖線で示した切断線で切
断して行なわれ、その切断線の内側に立上り面2cが残
る。As shown in FIG. 5, such an opening 2 is manufactured by cutting a protrusion 5, which is a part of the ventilation duct 1 protruding outward, at a cutting line indicated by a two-dot chain line during blow molding of the ventilation duct 1. This is done by cutting at the cutting line, and a rising surface 2c remains inside the cutting line.
このようにして立上り面2cを残すのは通風ダクト1の
他の表面に傷を生じさせないためである。The reason why the rising surface 2c is left in this way is to prevent other surfaces of the ventilation duct 1 from being damaged.
