Abstract

<P>PROBLEM TO BE SOLVED: To provide a level raising material for an automobile capable of further reducing weight, by securing required strength corresponding to a partially applied concentrated load. <P>SOLUTION: This level raising material is arranged on a floor pan of the automobile, for forming a floor surface in the required height. The level raising material 1 is arranged over a front wall surface under a dashboard of a vehicle and a recessed part of the floor surface continuing with its front wall surface, for allowing an occupant sitting down on a seat to keep an easy posture by placing feet. The level raising material forms a hollow double wall structure integrated with a shock absorbing part 7 corresponding to the recessed part of the floor surface, a foot placing part 8 corresponding to the front wall surface under the dashboard, and a bending part 9 for connecting its mutual parts. A core material 12 is fused on a reverse surface of the foot placing part 8 in a hollow part 11 of the hollow double wall structure. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

Description

本発明は、自動車のフロアパンに設置して床面を所要の高さにするための自動車用嵩上げ材に関するものである。   The present invention relates to a raising material for automobiles that is installed on a floor pan of an automobile to make the floor surface a required height.

自動車のフロアパンに設置して床面を所要の高さにするための自動車用フロア嵩上げ材としては、フロアパンとカーペットとの間に介在させて床面を嵩上げするものであって、射出成形により成形された発泡倍率が20〜45倍の発泡プラスチック製のものは、特開2001−347872号公報に記載されている。   The floor raising material for automobiles, which is installed on the floor pan of an automobile to raise the floor surface to a required height, is interposed between the floor pan and the carpet to raise the floor surface, and is injection molded. The one made of foamed plastic having a foaming ratio of 20 to 45 times formed by the method described in JP-A-2001-347872.

また、硬質発泡プラスチックからなるフロア嵩上げ材であって、表面が発泡体がであり、裏面側にリブまたは突起を形成して軽量でかつ高い剛性を有するものとしては、特開2003−127796号公報に記載されている。   JP-A-2003-127796 discloses a floor raising material made of hard foamed plastic, the surface of which is a foam, and ribs or protrusions are formed on the back surface side to provide light weight and high rigidity. It is described in.

また、特開2005−153757公報には、ブロー成形による中空二重壁構造体で、表側に細いスリットリブで補強したものが紹介されている。

Japanese Patent Application Laid-Open No. 2005-153757 introduces a blown hollow double-wall structure that is reinforced with thin slit ribs on the front side.
JP 2001-347872 A JP 2003-127796 A JP 2005-153757 A

自動車のフロアは、フロアパンの上にフロア嵩上げ材を設置してその上にカーペットを敷いた構成となっているが、フロア嵩上げ材には部分的に大荷重がかかることがあり、このような場合には、荷重の集中によって亀裂等の基材破壊の生じることが指摘されている。   The floor of an automobile has a structure in which a floor raising material is installed on a floor pan and a carpet is laid on the floor raising material. In some cases, it has been pointed out that the destruction of the substrate such as a crack occurs due to the concentration of the load.

また、前掲の特開2005−153757公報において紹介されている嵩上げ材は、その表面にスリットリブが細い溝として残り、靴のヒールが挟まるなどの不都合がある。   Further, the raising material introduced in the above-mentioned Japanese Patent Application Laid-Open No. 2005-153757 has a disadvantage that the slit rib remains as a thin groove on the surface and the heel of the shoe is caught.

フロア嵩上げ材においては、その全体の強度を増して剛性を高くすれば荷重の集中による基材破壊を防ぐことができるが、この種のフロア嵩上げ材は一方において軽量化も要求されるので、所要の強度を確保しつつ一層の軽量化も進めなければならない。加えて靴のヒールが挟まるなどの問題点の解消も重要である。   In the floor raising material, if the overall strength is increased and the rigidity is increased, the base material can be prevented from being destroyed due to the concentration of the load. However, this kind of floor raising material is required to be lighter on the other hand. It is necessary to further reduce the weight while ensuring the strength of the steel. In addition, it is important to eliminate problems such as the shoe heel getting caught.

そこで、本発明は、嵩上げ材を構成する中空二重壁構造体の中空部に、表壁の裏面に芯材を融着させることにより、部分的にかかる集中荷重に対応する所要の強度を確保でき、しかも一層の軽量化を実現することができるとともに、加えて靴のヒールが挟まるなどの問題点を解消することができる自動車用嵩上げ材を提供することを目的とするものである。   Therefore, the present invention secures the required strength corresponding to the partially concentrated load by fusing the core material to the back surface of the front wall in the hollow portion of the hollow double wall structure constituting the raising material. In addition, it is an object of the present invention to provide a vehicle raising material that can achieve further weight reduction and can solve problems such as a shoe heel being caught.

上記目的を達成するための本発明の請求項1に係る自動車用嵩上げ材は、車両のダッシュボード下方の前方壁面とそれに連なるフロア面の凹部とにわたって配置して、座席に座った搭乗者が足を載せて楽な姿勢を保たせるための足載せ部を一体として、フロア面の凹部に対応する衝撃吸収部と、ダッシュボードの下方の前方壁面に対応する足載せ部と、その間を繋いでいる屈曲部とが一体となった中空二重壁構造体をなし、前記中空二重壁構造体の中空部には、前記衝撃吸収部の表壁の裏面に芯材を融着させ、衝撃吸収部の裏壁に複数の補強リブを有する、ことを特徴とする。 In order to achieve the above object, a vehicle raising material according to claim 1 of the present invention is disposed over a front wall surface below a dashboard of a vehicle and a recessed portion of a floor surface connected thereto, so that a passenger sitting on a seat can The footrest part for maintaining a comfortable posture by placing the footrest is integrated with the shock absorbing part corresponding to the concave part of the floor surface and the footrest part corresponding to the front wall surface below the dashboard. A hollow double wall structure united with a bent portion is formed, and in the hollow portion of the hollow double wall structure , a core material is fused to the back surface of the front wall of the shock absorption unit, and the shock absorption unit The back wall has a plurality of reinforcing ribs .

本発明に係る自動車用嵩上げ材において、芯材としてハニカム構造の補強体を備えていることが好適である。   In the vehicle raising material according to the present invention, it is preferable that a reinforcing member having a honeycomb structure is provided as a core material.

本発明によれば、嵩上げ材を構成する中空二重壁構造体の中空部に、表壁の裏面に芯材を融着させることにより、部分的にかかる集中荷重に対応する所要の強度を確保でき、しかも一層の軽量化を実現することができるとともに、加えて靴のヒールが挟まるなどの問題点を解消することができるものである。   According to the present invention, the required strength corresponding to the partially concentrated load is secured by fusing the core material to the back surface of the front wall in the hollow portion of the hollow double wall structure constituting the raising material. In addition, the weight can be further reduced, and problems such as a shoe heel being caught can be solved.
