Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a suspended ceiling material for automobiles, which is one of automobile interior materials.

(Prior art) An automobile in which a plurality of tucks are formed on a sheet-like material, and the base of each tack is welded into a narrow strip-like welded part to form a plurality of elongated wire insertion parts parallel to the upper surface of the main body of the ceiling material. It is already known that a suspended ceiling material can be easily obtained by simply wrapping each side edge of the material around a body flange and suspending it using a staying wire inserted through each wire insertion portion.
(For example, Japanese Utility Model Application No. 59-11070) (Problem to be solved by the invention) However, in conventional suspended ceiling materials for automobiles, tack remains partially in the rolled-up parts on both sides, so the body When wrapping both sides of the ceiling material around the flange and fitting the weather strip or opening trim, a gap is created between them due to the thickness of the tack, making it difficult to obtain an appropriate tension state, and the gap There is a risk of rainwater infiltrating, and there is also the problem that when cutting the portion remaining due to the entrainment with a knife or the like, the tacked portion is difficult to cut, resulting in poor workability. In order to solve this problem, a method in which both ends of the tack are cut out in advance is disclosed in Japanese Patent Application Laid-Open No. 59-45116 and Japanese Patent Application Laid-Open No. 56
-163972 or Japanese Utility Model Application Publication No. 149016/1983, etc., even if both ends of the tack are notched in advance, the wall thickness of the remaining notch becomes a problem, and it is necessary to enlarge this notch. If it is completely eliminated, the problem arises that the strength and shape retention of the wrapping portion are lost, and it has not yet been possible to construct a suspended ceiling that can be wrapped around the body flange of an automobile accurately and easily and in an extremely stylish manner.

(Means for Solving the Problems) The present invention aims to provide a suspended ceiling material for automobiles that solves the above-mentioned problems at a low cost. In the suspended ceiling material for automobiles, the wire insertion part is formed by welding the bent base of a tack part formed by bending a sheet-like material with a narrow band-shaped welded part, and At both ends, widened welded parts in the form of thin eaves plates that reach the edges of the sheet material and are lower than the tacked parts are successively installed to create widened welded parts that can overlap both sides of the main part of the ceiling material with the sheeted material. It is characterized in that it is formed into a substantially flat winding portion.

(Function) In such a suspended ceiling material for automobiles, the resting wire is inserted into a plurality of elongated wire insertion portions formed at required intervals on one side of the main body of the ceiling material, and both ends of the resting wire are inserted. At the same time, the ceiling material is hung on the ceiling of the body, and the substantially flat winding parts on both sides of the main body of the ceiling material are rolled into the body flanges, and the weather strip and opening trim are fitted into the winding parts to perform ceiling interior decoration. That's fine.

(Example) Next, the present invention will be explained in detail by referring to an illustrated example.

Reference numeral 1 is a ceiling material main body, and the ceiling material main body 1 is made of a single sheet-like material such as a vinyl chloride resin sheet, and a plurality of elongated wire insertion parts 4 are arranged at required intervals on one side of the material. be. Each wire insertion part 4
A plurality of tucks 2 are bent at required intervals on one side of a sheet-like material, and a welded band 3 with a width of 2 to 5 mm is formed along the bent base of each tack 2 by welding. The weld thickness is completely thinned at both end portions of each tack 2, and the lower part of the thin weld portion is left uncut as a thin eaves plate-shaped widened weld portion 3a, which is approximately twice the width of the strip-shaped weld portion 3. Formed by cutting an arcuate vertical cut line 6 from the upper edge slightly inside the edge toward the narrow strip welded part 3, and a horizontal cut line 7 from the middle of the edge of the thin welded part so as to reach the lower end of the vertical cut line 6. It has been done. Reference numeral 5 denotes a substantially flat winding part formed on both sides of the ceiling material main body 1, and the winding part 5 has the above-mentioned tuck part on the back side of a single sheet-like material that reaches the edge of the sheet-like material. Thin eave plate-shaped widened welded part 3 lower than 2
Only part a is formed to be superimposable and becomes substantially flat when rolled up. Incidentally, the vertical cut line 6 and the horizontal cut line 7 may be always formed as perforation-like cut lines, and these portions may be broken and formed at the time of assembly to the body.

(Function) In the device constructed in this way, the remaining wires 8 are inserted into the elongated wire insertion portions 4 arranged at required intervals on one side of the main body of the ceiling material 1, and held at both ends. While suspending the body 9 on both sides of the ceiling, both sides of the ceiling material main body 1 are wrapped around the body flange 10, the excess portion is cut off with a knife, etc., and the opening trim 11 and weather strip are attached to the wrapped portion. By fitting together, it becomes a suspended ceiling, but the ceiling material main body 1
On both sides of the sheet-like material, only widened welded parts 3a, which are lower than the tuck part 2 reaching the edge of the sheet-like material, are formed on the back side of the sheet-like material so that they can be overlapped with the sheet-like material, so that it is substantially flat when rolled up. Therefore, unevenness due to the thickness of the tack does not occur in the rolled-up part, and there is no gap between the opening trim 11 and the weather strip that are fitted here, and the belt-shaped welded part 3 and Due to this and the existence of a series of widened welded parts 3a, each part is uniformly tensioned, and there is no fear of wrinkles or sagging. Moreover, the wire insertion part 4 is formed into a bag shape by forming a tack 2 which is formed by bending a sheet-like material and having a thin strip-like welded part 3 along the bending base, and a linear pattern remains on the surface side. This alone gives it an extremely good appearance and an excellent interior effect. Furthermore, since the widening welded part 3a is formed in the main body 1 of the ceiling material next to the large number of tuck parts 3 up to the edge, the substantially flat winding part 5 does not become insufficient in terms of strength. After the flat winding portion 5 is wound around the body flange 10, the excess portion can be easily cut off with a knife or the like, making it easy to suspend the body from the ceiling.

(Effects of the Invention) As is clear from the above description, the present invention is a suspended ceiling material for automobiles in which an elongated wire insertion portion is formed on one side of the sheet material. On the back side of the sheet material, a widened welded part that can be overlapped with the sheet material is formed so that it can be overlapped, and the wrapping part becomes substantially flat when rolled up, but the wrapping part becomes insufficient in terms of strength. It is possible to accurately and easily wrap the weld onto the car body flange without reducing shape retention and causing wrinkles, and the widened welded part is shaped like a thin eaves plate and is easy to cut, making it easy to cut the excess edge of the wrapping part. The finishing work of cutting and removing after wrapping is easy, and a suspended ceiling can be constructed in an extremely attractive manner.
It has great practical value as it solves the problems of conventional suspended ceiling materials for automobiles.
