Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method of manufacturing a door.

[Problems to be solved by conventional techniques and inventions] Generally,
A door such as a flush door consists of a top and bottom stile, a left and right vertical stile, a middle stile, a panel inserted into the stile, etc., and the panel has a thin end that has various types of walls or a middle stile. It was fitted into a groove formed in the crosspiece.

Therefore, the manufacturing process is troublesome, the manufacturing cost is high, and as mentioned above (manufactured doors do not warp or twist).
Such deformations were likely to occur.

Therefore, it is an object of the present invention to provide a manufacturing method that can easily and inexpensively manufacture a door that does not undergo deformation such as "warping" or "twisting", has excellent strength, and has a good appearance. purpose.

[Means to solve the problem]

In order to achieve the above-mentioned object, the method for manufacturing a door according to the present invention involves bonding an air permeable plate material to the front side of a flat air permeable substrate to form a design uneven surface. , by covering the above-mentioned uneven design surface with a thermoplastic film-like body that has been heated in advance, or by heating a rectangular film-like body that has covered the above-mentioned uneven design-like surface with an unheated thermoplastic film-like body. , the film-like body is sucked to the back side of the substrate, and the film-like body is brought into close contact with the above-mentioned uneven design surface to form a base member, and then the pair of base members are arranged so that their back faces face each other. The base members are arranged back-to-back, and a core material is interposed between the base members to bond and integrate the base members. , After bonding together breathable plate materials to form a design uneven surface, the design uneven surface is covered with a preheated thermoplastic film, or an unheated thermoplastic film. The double line film-like body covering the design-use uneven surface is heated, the film-like body is sucked to the back side of the substrate, the film-like body is brought into close contact with the above-mentioned design-use uneven surface, and the film-like body is heated. A base member is formed by applying a surface treatment such as an embossed pattern to the surface on the front side of the body, and then a pair of the base members are arranged back to back with their back sides facing each other, and the base member is A core material is interposed between the members, and the base members are bonded and integrated.

[For production]

A design-use uneven surface can be formed by bonding a plate material to the front surface of the substrate, and if the film-like material is sucked to the back side of the substrate, both the substrate and the plate material have air permeability. The film-like material adsorbs easily and reliably. Then, the door is completed by bonding and integrating the pair of base members through the core material, so the completed door has excellent strength, and it can be manufactured using the same method as in the past. This is extremely easy and inexpensive compared to fitting the panel into the groove. Even though it is such a cheap product, the textured surface for design is covered with a film-like material, so if you apply a design such as wood grain to the film-like material, it will not feel cheap, but rather will have a high-class feel. It does.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 2 shows a door 1 manufactured by the door manufacturing method according to the present invention. , a middle vertical beam part 8.9, and a panel part 10... In this case, as shown in FIG. 10, a pair of front and rear base members 11, 11, and the base member
．． It consists of a core material 12° 12 interposed between 11 and 11.

Thus, the base member 11 is connected to the substrate 1 as shown in FIG. 1D.
3, a plate material 15 bonded to the front surface 14 of the substrate 13, and a film-like body 16 closely adhered to the substrate 13 to the plate material 15. In the embodiment, the thickness of the substrate 13 is approximately 2.5 mm, and the thickness of the board 15 is approximately 6 mm.
(2), but of course it is not limited to this.
A design uneven surface 17 is thus formed. In other words, the film-like body 16 is in close contact with this uneven surface 17. Also,
The pair of base members 11.11 are arranged back to back so that the back surfaces 18.18 face each other, and the core member 12.1
They are integrated by adhesive via 2. Note that the panel portion 10 is constituted by the concave portions 17a of the uneven surface 17, and the convex portions 17
b constitutes the stile 2.34.5 and the crosspieces 6, 7.8.9. That is, in FIG. 10, the convex portions 17b, 1
7b corresponds to the left and right vertical frames 4 and 5.

Next, a method of manufacturing the door constructed as described above will be explained.

First, as shown in FIG. 1A, a plate material 15.15 is adhered to the front surface 14 of a flat substrate 13 to form a design uneven surface 17. Here, the base 13 and the plate material 15 are made of an air permeable material such as plywood or particle board.

Next, the board 13 to which the plate material 15.15 is attached is placed in the first B
As shown in the figure, it is placed on the receiving plate 19, and the film-like body 16 is placed on the design uneven surface 17. Here, the film-like body 16 is made of thermoplastic synthetic resin, such as vinyl chloride, and has a thickness of, for example, 0.1 to
It consists of an extremely thin body of 0.3 mm.

Then, from this state, the film-like body 16 is sucked to the back side of the substrate 13 by the vacuum device 20, but in this case, the uneven surface 17 is coated with an adhesive. Here, vacuum device 2
0 includes a main body 21 that receives the receiving plate 19 and a vacuum pump (not shown), and the main body 21 has a recess 22.
A communication hole 23 is connected to the recess 22 . The communication hole 23 is connected to the vacuum pump (not shown), and the vacuum chamber 25 formed by the recess 22 and the back surface 24 of the receiving plate 19 is brought into a vacuum state. Further, the receiving plate 19 is provided with a large number of communication passages 27 through which the front surface 26 and the back surface 24 communicate with each other.

Therefore, if the vacuum chamber 25 is in a vacuum state, both the substrate 13 and the plate material 15 have air permeability, so the film-like material 16
is attracted to the uneven surface 17.

In this case, the end portion 28 of the film-like body 16 is
It is pressed and sealed with a presser lid 29. That is, this presser lid 29 consists of an upper wall 30 and a side wall 31.
The lower edge 32 of the film-like body 16 is pressed against the end 28 of the film-like body 16, and is opened and closed by reciprocating as shown by the arrow by a cylinder mechanism 33. Further, a through hole 34 is provided in the upper wall 30, hot air or the like is sent through the through hole 34, the inside of the lid 29 is a pressure chamber 35, and the film-like body 16 has an uneven surface 17 as shown by the arrow.
Pressed to the side.

Therefore, when hot air is sent into the lid 29, the film-like body 16
is heated and becomes easily deformed, and if the vacuum chamber 25 is brought into a vacuum state in this state, the film-like body 16 will be subjected to the pressing force in the direction of the arrow of the pressure chamber 35 and the uneven surface 17 of the vacuum chamber 25. A suction force is applied to the side, and as shown in FIG. 1C, the film-like body 16 is firmly brought into close contact with the uneven surface 17 without any gaps. In this embodiment, an adhesive is applied to the uneven surface 17, but if the film-like body 16 has heat-fusibility or the like, the film can be coated by heating without using an adhesive. The shaped body 16 can be brought into close contact with the uneven surface 17.

Moreover, if the air sent into the lid 29 is not hot air, the film-like body 16 may be heated in advance before it is placed on the uneven surface 17. Note that the heating temperature is approximately 150 @C in both cases.

Next, a pair of base members 11 is formed, and as shown in FIG. Material 12
．． 12 is inserted, and the core material 12.12 and the base member 11.degree. 11 are bonded together with an adhesive, and the door 1 is completed.

Therefore, it is preferable that the film-like body 16 has various designs such as wood grain on the surface.Furthermore, when the film-like body 16 is in close contact with the uneven surface 17 and is in a heated state, etc. It is also possible to perform surface processing such as embossed pattern processing. Specifically, a roller or the like engraved with various patterns is pressed against the surface of the film-like body 16. Further, in addition to this embossed pattern, surface processing to make the surface of the film-like body 160 mirror-like is also possible.

Note that the present invention is not limited to the above-described embodiments, and the design may be changed without departing from the gist of the present invention. For example, the number of plates 15 to be bonded to the substrate 13 is not limited to two, By increasing the number or using different thickness dimensions, the design uneven surface 17 can be changed, and doors 1 of various shapes can be manufactured.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

It is not necessary to form grooves in the frame and fit panels into the grooves as in the past, and the door 1 can be manufactured easily and at low cost. It also has excellent properties and is less prone to deformations such as warping and twisting. In addition, although it is manufactured at a low cost, the surface of the film-like body 16 can be decorated with various designs such as wood grain, and even embossed patterns, giving it a high-class feel. I can do it.
