【考案の詳細な説明】
本考案は自動車の天井に取付けられる内装材に
関する。[Detailed Description of the Invention] The present invention relates to an interior material that is attached to the ceiling of an automobile.
従来一般に用いられているこの種の内装材は第
１図及び第２図に示す構造のものである。すなわ
ち、基材１（ハードボード）にウレタンフオーム
等の軟材２と塩化ビニル等の表皮３を重ね合せ、
表皮面上より適当な間隔で加熱溶接による筋押し
５を施し、表皮３の端末４は軟材２と基材１との
端を巻込み、接着剤によつて基材１の外面に接着
した構造である。 This type of interior material that has been commonly used in the past has the structure shown in FIGS. 1 and 2. That is, a soft material 2 such as urethane foam and a skin 3 such as vinyl chloride are superimposed on a base material 1 (hardboard),
Strets 5 were applied by heat welding at appropriate intervals on the surface of the skin, and the ends 4 of the skin 3 were wrapped around the ends of the soft material 2 and the base material 1 and bonded to the outer surface of the base material 1 with adhesive. It is a structure.
この従来の構造では、基材１の表皮３との間の
空間は密封状態となつているため、ルーフに照射
する太陽熱等により内部に閉じこめられた空気が
膨張し、表皮がたれ下る等の熱変形を起して外観
を低下する不具合があつた。 In this conventional structure, the space between the base material 1 and the skin 3 is sealed, so the air trapped inside expands due to solar heat irradiating the roof, causing the skin to sag. There was a problem that deformation occurred and the appearance deteriorated.
本考案は上記従来の不具合を解消したものであ
る。その実施例について第３図乃至第５図によつ
て説明する。 The present invention solves the above-mentioned conventional problems. The embodiment will be explained with reference to FIGS. 3 to 5.
１は基材、２は軟材、３は表皮、５は加熱溶接
による筋押しであり、従来の構成と同一である。 1 is a base material, 2 is a soft material, 3 is a skin, and 5 is a reinforcement by heat welding, which is the same as the conventional structure.
本考案は上記の構成において表皮３の端末を巻
き込まないで、基材１及び軟材２の端面と略揃つ
た切断端末とし、該表皮３端を所定の間隔で局部
的に加熱溶接６し、該加熱溶接６間の非加熱溶接
部分を通気路７として形成したものである。 In the present invention, in the above structure, the ends of the skin 3 are not rolled up, but are cut into ends that are substantially aligned with the end surfaces of the base material 1 and the soft material 2, and the ends of the skin 3 are locally heated and welded 6 at predetermined intervals. The non-heat welded portion between the heat welds 6 is formed as a ventilation passage 7.
本考案は上記の通りの構造であるから、ルーフ
に照射される太陽熱や室内の高温によつて基材１
と表皮３との間の気体が熱膨張しても、その空気
は非加熱溶接部分の通気路７より速かに外部に放
出する。従つて気体の熱膨張による表皮３の熱変
形は防止し、外観美を保持するものである。 Since the present invention has the above-mentioned structure, the base material 1
Even if the gas between the surface and the skin 3 thermally expands, the air is discharged to the outside more quickly than the air passage 7 of the non-heated welded part. Therefore, thermal deformation of the skin 3 due to thermal expansion of the gas is prevented and the appearance is maintained.
以上のように本考案によると、従来のような熱
膨張による表皮の熱変形の不具合を解消すると共
に、表皮端末の巻き込み作業が不要となるので、
製造作業能率が向上し、巻き込み分だけ表皮の節
約が得られる利点がある。 As described above, the present invention eliminates the conventional problem of thermal deformation of the epidermis due to thermal expansion, and eliminates the need to wrap the ends of the epidermis.
This has the advantage of improving manufacturing efficiency and saving the skin by the amount of wrapping.

自動車用天井の内装材。 In an interior material in which a soft material such as urethane foam and a skin such as vinyl chloride are layered on the base material, and striations are applied by heat welding at appropriate intervals from the surface of the skin, the edge of the skin is connected to the edge of the base material and the soft material. An interior material for an automobile ceiling, in which substantially even cut ends are formed, the skin edges are locally heat-welded at predetermined intervals, and non-heat welded areas between the heat welds are used as air passages.
