ンパーレインホースメントに関するものである。That is, according to the present invention, a large number of pyramid-shaped depressions whose tip portions are welded to the front wall surface are provided on the rear wall surface of the hollow cylindrical body at appropriate intervals, and a plate-shaped rib is stretched between the depressions. The present invention relates to a one-piece type resin bumper rain hosement.
本発明は上記の構成に基づいて下記の特徴を有する。 The present invention has the following features based on the above configuration.
ａ）構成要素である前後の壁及び板状リブが中空筒体か
ら一体に形成され、かつ、それ自身で（ワンピース型
の）バンパーを構成する。a) The front and rear walls and the plate-like rib which are the constituent elements are integrally formed from the hollow cylindrical body, and themselves constitute a (one-piece type) bumper.
ｂ）窪みは頂点が前部壁面に溶着するピラミッド型を有
しているので、車に装着したとき、４側面は前方のピラ
ミッド頂点に向かうよう傾斜すると共に、前端面は地面
に対して直角となる。b) Since the dent has a pyramid shape in which the apex is welded to the front wall surface, when mounted on a car, the four side surfaces are inclined toward the front pyramid apex, and the front end face is perpendicular to the ground. Become.
ｃ）板状リブはピラミッド型窪みの前端面に直角であ
り、自動車に装着された際、地面に対して平行な面内で
窪み相互を連結する。c) The plate-shaped ribs are perpendicular to the front end face of the pyramid-shaped recess, and connect the recesses in a plane parallel to the ground when mounted on a vehicle.
作用 本発明は上記構成に基づき、下記の作用を示し得る。Action The present invention can exhibit the following actions based on the above configuration.
ａ）前方からの衝撃には窪み４側面が補強作用を示す。a) The side surface of the dent 4 has a reinforcing effect against the impact from the front.
ｂ）上下方向の衝撃には、窪みの前側面と、窪みの間に
地面に平行に配された板状リブが補強作用を示す。b) In the vertical impact, the front side surface of the depression and the plate-shaped ribs arranged between the depressions and parallel to the ground have a reinforcing effect.
ｃ）斜め方向の力には、板状リブと窪みが協同して補強
作用を示す。c) The plate-shaped rib and the depression cooperate with each other to exert a reinforcing effect on the oblique force.
ｄ）さらに、ピラミッド型窪みの前後面以外の４側面が
傾斜している結果、上記ａ）及びｃ）に記載の効果をさ
らに補強するよう作用する。d) Furthermore, as a result of the four side surfaces of the pyramid-shaped recess other than the front and rear surfaces being inclined, the effect described in a) and c) above is further strengthened.

る。EXAMPLE The present invention will be described with reference to the illustrated example. FIG. 1 is a front view in which a front wall surface (2) of a hollow cylindrical body (1) is partially cut away, and a rear wall surface (3) is recessed in the cut portion. The box-shaped recesses (4) formed by the above and the plate-shaped ribs (5) stretched between the recesses (4) and the recesses (4) can be seen. The section of the front wall surface (2) is in close contact with the tip of the depression (4).
