【考案の詳細な説明】
この考案はたとえば自動車用サイドシルカバー等のプラ
スチック部品の取付構造に関するものである。[Detailed Description of the Invention] This invention relates to a mounting structure for plastic parts such as side sill covers for automobiles.
プラスチック部品を本体部品などに取付ける場合、プラ
スチック部品が熱により伸縮するので、この伸縮に適応
するようにその取付部が構成されている。When attaching a plastic component to a main body component, etc., the plastic component expands and contracts due to heat, so the mounting portion is configured to accommodate this expansion and contraction.
第１図、第２図は従来例の取付構造を示すもので、本体
部品１にプラスチック部品２を取付スクリュ３で締着す
るようにしたものある。1 and 2 show a conventional mounting structure, in which a plastic part 2 is fastened to a main body part 1 with a mounting screw 3.
取付スクリュ３を取付けるために、プラスチック部品２
の取付部２ａに熱により伸縮する方向を長径とする長孔
２ｂが設けてあり、取付スクリュ３には頭部３ａの下に
円筒形の段部３ｂが形成してある。To attach the mounting screw 3, remove the plastic part 2.
The mounting portion 2a is provided with a long hole 2b whose major diameter is in the direction of expansion and contraction due to heat, and the mounting screw 3 has a cylindrical stepped portion 3b formed below the head 3a.
段部３ｂは頭部３ａより小径で、長孔２ｂに嵌押される
。The stepped portion 3b has a smaller diameter than the head portion 3a, and is fitted into the elongated hole 2b.
従って長孔２ｂの短径（幅）は頭部３ａの外径より小さ
い。Therefore, the short axis (width) of the long hole 2b is smaller than the outer diameter of the head 3a.
また段部３ｂの高さは長孔２ｂを設けた取付部２ａの高
さより一段高く形成してあり、スクリュー３を取付けた
とき頭部３ａと取付部２ａとの間に隙間ｅができる。Further, the height of the stepped portion 3b is formed to be one step higher than the height of the attachment portion 2a provided with the elongated hole 2b, and when the screw 3 is attached, a gap e is created between the head portion 3a and the attachment portion 2a.
従って取付スクリュ３は頭部３ａの下にプラスチック部
品２の取付部２ａを挾むようにして本体部品に締着され
、熱によりプラスチック部品２が伸縮するとき、段部３
ｂに対して摺動により長孔２ｂの相対的位置が変るだけ
で、プラスチック部品２は本体部品１に取付けられてい
る。Therefore, the mounting screw 3 is tightened to the main body part so as to sandwich the mounting part 2a of the plastic part 2 under the head 3a, and when the plastic part 2 expands and contracts due to heat, the step part 3
The plastic part 2 is attached to the main body part 1 only by changing the relative position of the elongated hole 2b by sliding with respect to the plastic part 2b.
この構造においては、取付スクリュ３の頭部３ａの下に
段部３ｂを有するものを使用する必要があり、特殊形状
のスクリューとして高価になることを避けられない。In this structure, it is necessary to use a mounting screw 3 having a stepped portion 3b below the head 3a, which inevitably increases the cost of the specially shaped screw.
そこでたとえば実開昭５３−１２０４０６号公報に示す
ように、段のない取付スクリュを使用するものもあるが
、本考案は第３図〜第５図に示す実施例のように形成し
て、段のない安価な取付スクリュを使用することになっ
ており、その詳細は次の通りである。Therefore, as shown in Japanese Utility Model Application Publication No. 53-120406, there are some installation screws that use a stepless mounting screw, but the present invention has a mounting screw formed as shown in FIGS. The details are as follows.
これは本体部品４にプラスチック部品５を取付スクリュ
６で締着するようにしてあり、取付スクリュ６は頭部６
ａのみを有する普通の形状のものである。The plastic part 5 is fastened to the main body part 4 with a mounting screw 6, and the mounting screw 6 has a head 6.
It has a normal shape with only a.
プラスチック部品５には、取付スクリュ６のネジ部６ｂ
を嵌押する長孔からなる取付孔５ａが設けである。The plastic part 5 has a threaded portion 6b of the mounting screw 6.
A mounting hole 5a consisting of an elongated hole into which the holder is inserted is provided.
また取付孔５ａを設けたボス部５ｂの外周に、環状溝５
Ｃが設けである。Further, an annular groove 5 is provided on the outer periphery of the boss portion 5b provided with the mounting hole 5a.
C is provided.
環状溝５Ｃはプラスチック部品５において熱により伸縮
する方向を長径ｆとするように形威してあり、これに直
交する短ｉｇは取付スクリュ６の頭部６ａの外径りより
小になるように形威しである。The annular groove 5C is shaped so that the direction in which it expands and contracts due to heat in the plastic part 5 is the major axis f, and the short axis ig perpendicular to this is smaller than the outer diameter of the head 6a of the mounting screw 6. It's a formality.
またボス部５ｂにおいて取付スクリュ６の頭部６ａが当
接する接面部５ｄを、環状溝５ｃの外側部５ｅの面部５
ｆより、一段高く形成するようにしである。In addition, the contact surface 5d of the boss 5b, which the head 6a of the mounting screw 6 comes into contact with, is replaced by the surface 5 of the outer portion 5e of the annular groove 5c.
It is designed to be formed one step higher than f.
さらに環状溝５ｅに対して、ボス部５ｂと外側部５ｅと
を伸縮方向に直交する方向の狭小な橋部５ｇ、５ｇでつ
ないで、プラスチック部品５の全体を一体に成形するよ
うにしである。Further, with respect to the annular groove 5e, the boss portion 5b and the outer portion 5e are connected by narrow bridge portions 5g, 5g in a direction perpendicular to the direction of expansion and contraction, so that the entire plastic part 5 is integrally molded.
そこで取付スクリュ６をプラスチック部品５の取付孔５
ａに嵌押し本体部品４にねじ込むと、ボス部５ｂが本体
部品４に固定される。Then, insert the mounting screw 6 into the mounting hole 5 of the plastic part 5.
The boss portion 5b is fixed to the main body part 4 by fitting and screwing it into the main body part 4.
そしてプラスチック部品５が熱により伸縮するようにな
ると、固定したボス部５ｂに対して外側部５ｅが移動す
るようになるから、これをつなぐ橋部５ｇｖ５ｇが切断
される。When the plastic part 5 expands and contracts due to heat, the outer part 5e begins to move relative to the fixed boss part 5b, and the bridge part 5gv5g connecting this part is cut.
ボス部５ｂの接面部５ｄは外側部５ｅの面部５ｆより一
段高く形威しであるから、接面部５ｄに当接する取付ス
クリュ６の頭部６ａと外側部５ｅの面部５ｆとの間には
隙間ｋができている。Since the contact surface portion 5d of the boss portion 5b is one step higher than the surface portion 5f of the outer portion 5e, there is a gap between the head 6a of the mounting screw 6 that contacts the contact surface portion 5d and the surface portion 5f of the outer portion 5e. k is completed.
また環状溝５ｃの短径ｇは取付スクリュ６の頭部６ａの
外径りより小さいから、外側部５ｅは取付スクリュ６の
頭部６ａを越えて抜は出すことがない。Further, since the minor diameter g of the annular groove 5c is smaller than the outer diameter of the head 6a of the mounting screw 6, the outer portion 5e does not extend beyond the head 6a of the mounting screw 6.
従って本体部品４に固定されているボス部５ｂに対して
環状溝５ｃを介して外側部５ｅが伸縮方向に移動するだ
けで、プラスチック部品５は本体部品４に取付けられて
いる。Therefore, the plastic part 5 is attached to the main body part 4 simply by moving the outer part 5e in the expansion/contraction direction with respect to the boss part 5b fixed to the main body part 4 via the annular groove 5c.
このようにしてプラスチック部品５に熱による伸縮を許
容するようになっており、プラスチック部品５の全体を
一体に成形するとともに、取付けに普通のスクリュ６を
用いることができるから、それぞれを安価に構成できる
という利点がある。In this way, the plastic part 5 is allowed to expand and contract due to heat, and since the entire plastic part 5 can be molded in one piece and ordinary screws 6 can be used for attachment, each part can be constructed at low cost. It has the advantage of being possible.
