Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a lining for a door finisher such as a front door or a rear door of an automobile. More specifically, it relates to the provision of a door structure in which the trim surface of the door finisher is covered with a natural wood board.

(Prior Art) Conventionally, the trim surface of a door finisher is covered with a resin sheet material such as PVC on the assumption that the decorative problem and the touch feeling at the time of contact, abrasion resistance, etc. are comprehensively satisfied. There were many

However, it is obvious that this type of resin sheet material is a resin sheet material even if it is textured or made into synthetic leather, and it tends to significantly impair the decorative beauty in the vehicle. Was.

Therefore, there was one intended to give a more natural texture by using a resin sheet material on the trim surface as a decorative sheet printed in a grain pattern or by attaching a grain pattern print to the sheet fabric side. .

However, in both cases, the feeling of touch is poor,
It has a drawback that it can be immediately identified as a resin sheet material.

From this point of view, it was attempted to bring out the decorative beauty of the door finisher by covering the trim surface with cloth or carpet.

(Problems to be solved by the present invention) However, such a resin sheet such as PVC or a synthetic leather material has difficulty in breathability and hygroscopicity, and has a sticky feeling in the summer and in the winter. Caused a dry feeling and generated static electricity, and also caused dew condensation and sweating when heating or cooling the room.

In addition, since it is used in a vehicle where the temperature changes drastically, the degree of expansion and contraction is great, and the sheet material tends to be cracked and wrinkled, and the durability tends to be extremely poor.

Further, in the case of a decorative printed fabric or the like, since the print is extremely thin, the pattern portion may be immediately lost due to scratches and the like, and the decorative durability tends to be poor.

Also, if a cloth or carpet material is sewn into the trim for the purpose of making it feel good to the touch, the cloth or carpet material is subject to excessive wear, and the trim surface decoration function will be impaired in an extremely short period unless careful handling is performed. However, this replacement cost a lot of money.

(Specific Means for Solving Problems) The automobile door according to the present invention directly uses a natural wood board for the trim sticking in the conventional example, and further, this wood board is used. It is the one that promises both the decorativeness and functionality of the trim at the same time without cracking, breaking or tearing. That is, the automobile door of the present invention contains 0.1 to 10% of cellulose-based fine aggregate.
A decorative sheet in which a decorative board having a thickness of 0.1 to 0.3 mm is laminated and adhered to a thermoplastic resin film having a thickness of 0.8 mm is attached to a trim surface of a door finisher by using the surface of the resin film of the decorative sheet as an adhesive surface. All or part of the trim surface is covered with the decorative sheet.

(Embodiment) Hereinafter, a typical embodiment of a vehicle door according to the present invention will be described with reference to the accompanying drawings.

A is a door of an automobile, which is different in shape, size, and structure depending on the type of vehicle, purpose of use, difference in front or rear, and the like. A'is the finisher portion of this door, and a is its trim surface.

Incidentally, appropriate accessories such as an armrest b, a speaker grill c, a step lamp d, an inside handle e, and a door pocket f are integrally or separately attached to the trim surface a.

The decorative sheet 1 is stretched on the trim surface a of the finisher portion A'as described above. Usually, the basic shape of the finisher portion A'has a core plate 2 such as a hard board, an ABS board, or a PP board. Is typed,
A cushioning material 3 such as urethane foam is inserted in this and the decorative sheet 1 is stretched.

It should be noted that the cushioning material 3 is not molded by a method of stretching a foam material on the core plate 2, but after the decorative sheet 1 is stretched on the core plate 2, urethane is interposed between the decorative sheet 1 and the core plate 2. Foam may be injected and filled to fire. In this case, since the core plate 2 and the sheet 1 are sufficiently adhered and integrated by the foam material, there is no displacement of the cushioning material 3 due to use, and wrinkles of the sheet 1 are relatively unlikely to occur. .

Next, the decorative sheet 1 stretched over the trim surface a has the following configuration.

First of all, the resin film 1a prepared is prepared by mixing a dry 80-150 mesh finely powdered cellulosic aggregate, mainly wood powder, into a thermoplastic resin such as vinyl chloride, and kneading this with a calender roll. The film 1a having a thickness of 0.1 to 0.8 mm was used.

Then, the reinforcing fabric 1 laminated and adhered to the film 1a
Reference numeral b denotes a cloth or paper, or a cloth and a paper which are laminated together at the same time. Usually, when roll-forming the film 1a, the reinforcing cloth 1b is attached and fused to achieve the integration of the two. .

Further, the decorative skin plate 1c attached to the other surface of the film 1a is a natural ultrathin plate material having a thickness of 0.1 to 0.3 mm, and is adhered to the surface of the film 1a under sufficient pressure.
It is one. The surface of the film 1a may be sanded for the purpose of increasing the adhesiveness of the skid plate 1c. When the sanding is applied, the film 1a may be sanded.
Has the advantage that the skin layer portion on the surface thereof is removed to prevent distortion after molding.

The decorative sheet 1 molded in this manner is stretched on the trim surface a of the finisher portion A'in its original state, or the decorative sheet 1 is subjected to heat treatment again to make the decorative sheet 1 sufficient. It may be stretched in a state where the residual internal stress of the decorative sheet 1 is removed by shrinking or rolling again by rolling.

In the structure of the decorative sheet 1, the reinforcing cloth 1b may be omitted, and the sheet 1 including only the film 1a and the skid plate 1c may be prepared, and the sheet 1 may be attached to the trim surface a.

In addition, the decorative sheet 1 to be stretched may extend over the entire trim surface a, may stay only on a part of the trim surface a, and may be stretched simultaneously on the surfaces of the armrest b and the door pocket f. is there.

(Effect) The vehicle door according to the present invention has the following specific effects due to the above-mentioned characteristic structure.

(1) Since the skid plate 1c covers the trim surface a,
The trim surface is given a natural and deep decorative beauty, and yet it feels good to the touch. That is, since the skid plate 1c itself of the trim surface a has sufficient hygroscopicity and has an appropriate friction resistance, a comfortable living room space is created without a sticky feeling or a dry feeling.

Further, since the film 1a itself is formed into an ultrathin shape having a cellulosic aggregate, it has the same breathability and moisture permeability as the skid board 1c, which makes the skid board 1c feel even better.

(2) Therefore, even during heating and cooling, dew condensation or sweating does not occur on the trim surface, and since it is the luck plate 1c, it has sufficient abrasion resistance and does not generate static electricity.

(3) Further, the skid plate 1c is not cracked or split even after being stretched due to the presence of the film 1a, and is not peeled off after the stretching. Further, the flexibility of the wood board is further increased when the reinforcing cloth 1b is interposed, and the seat material can be adapted to any curved surface of the trim surface a.
