DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber-formed plate used as, for example, a face material of a flash door and a method of manufacturing a fitting using the fiber-formed plate.

[0002]

BACKGROUND ART Conventionally, doors, sliding doors, and other fittings have been made of a thick plate obtained by cutting natural wood. A structural fitting is provided. Previously, in the fittings of the flash structure, the core material and the thin plate material were also used by cutting natural wood. Using a fiber molded board manufactured by binding wood fibers with a synthetic resin such as phenolic resin and heat-pressing and curing into a predetermined shape as a face material, further saves wood resources and saves labor of craftsmen. Attempts have been made. The fiber molded plate has good moldability, and can easily apply an arbitrary uneven pattern such as a fine embossed pattern, a deep drawn embossed pattern and the like in one shot, so that the productivity is good, for example, as shown in FIG. Frame part (2), end plate part (3), decorative edge
It is useful as a surface material (1) for a flash door having (4) and the like, and it is not necessary to attach a conventional decorative edge (4) by post-processing, so that labor of a craftsman can be saved.

[0003]

The above-mentioned fiber molded board is left and cured at room temperature after hot press molding, and the curing of the synthetic resin contained in the curing proceeds, but immediately after the hot press molding, the fiber molded board is in a high temperature state. The thickness of the fiber molded plate after molding is relatively thin, about 2 to 4 mm, so that the center is centered on the dotted lines C ₁ -C ₁ and C ₂ -C ₂ , which are flat portions. Deformation such as warpage is likely to occur. And when the fiber molded plate is deformed, workability at the time of bonding to the core material deteriorates,
In addition, the fiber molded plate and the core material may be displaced, or cracks or cracks may be generated at the time of deformation correction, which may cause deterioration in product quality.

[0004]

The present invention SUMMARY OF THE INVENTION As means for solving the conventional problems described above, Oyo warp preventing the peripheral portion
Continuous rib groove for guide line and cutting line
It is intended to provide a fiber molded plate (1A) formed from (6).
The fiber molded plate (1A) is provided with an embossed pattern (5).
Is desirable. Further, a decorative sheet (8) is adhered to the surface of the fiber molded board (1A) to form a decorative fiber board (1).
When manufacturing the fittings (20) by bonding (1) to both sides or one side of the core material (7), the fibers are prepared before and / or after the decorative fiberboard (1) is bonded to the core material (7). Ca rib grooves (6) of the molded plate (1A)
The present invention provides a method of manufacturing a fitting (20) that cuts off the outer ear from the inside of the rib groove (6) as a guide of a setting line. In addition or the decorative sheet (8) pattern on the surface and /
Or colored and / or embossing the scan pattern (5) is attached
Is a plastic sheet you are, the decorative sheet (8) is the
It is bonded by vacuum pressing to the fiber molding board (1A).
Is desirable .

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described with reference to a specific example shown in FIGS. 1 to 8, in which a fiber molded plate (1
In A), a raw material mainly composed of a mixture of wood fiber and a phenol resin is formed into a mat shape, and the mat is pressed into an upper mold (9) and a lower mold (10) as shown in FIG. It is manufactured by hot pressing with a molding machine (11) and then curing. As shown in FIGS. 2 and 3, the fiber molded plate (1A) has a peripheral frame (2A) and a central horizontal frame (2B). And a center vertical frame part (2C), and a frame part (3) surrounded by a deep drawing embossed decorative edge (4) is formed on each of the frame parts (2A, 2B, 2C). On the surface, in addition to the decorative edge (4), which is the deep drawing embossed pattern, a fine grained embossed pattern
(5), and a rib groove (6) having a U-shaped cross section is formed on the outer periphery of the peripheral frame portion (2A). The fiber molded plate (1
In (A), deformation after hot press forming is prevented both in the vertical direction and in the horizontal direction by the rib effect of the rib groove (6).

[0006] Prior to the manufacture of a fitting, the fiber molded plate (1A) is provided with a rib groove along a dotted line aa as shown in FIGS.
(6) is cut from the inside, and both ears in the longitudinal direction are cut off as shown in FIG. The fiber molded plate (1A) from which the both ears in the longitudinal direction were cut off was then applied to a vacuum crimping device (1) as shown in FIG.
Set in 2), the decorative sheet (8) is vacuum-pressed on the surface using an adhesive.

The decorative sheet (8) is non-breathable, for example, polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-propylene terpolymer, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyvinylidene chloride, Polystyrene, polyvinyl acetate, fluorine resin, thermoplastic acrylic resin, thermoplastic polyester,
It consists of a plastic sheet of thermoplastic polyamide, thermoplastic urethane resin, acrylonitrile-butadiene copolymer, styrene-butadiene copolymer, acrylonitrile-butadiene-styrene copolymer, etc. And so on.

As shown in FIG. 5, the vacuum pressure bonding apparatus (12) includes a hollow lower plate (13) connected to a vacuum path (14), and a hollow lower plate (1).
3) an air-permeable porous layer (15) arranged on the upper side, and an upper panel (16) on which an air bag (17) is attached on the lower side, wherein the fiber molded plate (1A) is (15) It is set on, and a decorative sheet (8) is stacked on it via an adhesive, and a vacuum path (14)
Thus, vacuum suction is performed through the hollow lower plate (13) and the air-permeable porous layer (15), and the air bag (17) of the upper plate (16) is pressed from above the decorative sheet (8). Thus, the decorative sheet (8)
Is vacuum-pressed to a fiber molded plate (1A), the decorative sheet (8)
Are adhered following the shape of the decorative edge (4) on the surface of the fiber molded plate (1A), the fine embossed pattern (5) and the like.

The face material (1), which is a decorative fiberboard manufactured as described above, is bonded to both sides or one side of the core material (7) shown in FIG. 6 with an adhesive. This state is shown in FIG.
After the face material (1) is adhered to both sides of the core material (7) as shown in FIG. 7, the rib groove (6) is used as a guide of the cutting line and the face material ( The fiber molded board (1A) of 1) is cut from the inside of the rib groove (6) along the dotted line bb shown in FIG. 2 and both ears in the short direction are cut off. Thus, the fitting (20) as shown in FIG. 8 is manufactured.

In addition to the specific examples described above, the cutting of the ears of the fiber molded plate (1A) may be performed before or after the decorative sheet is bonded in both the longitudinal direction and the lateral direction, or the face material (1) may be attached to the core material (7). ) May be performed after bonding. Instead of bonding the decorative sheet, decorative coating may be applied directly to the fiber molded plate (1A). In this case, a transparent sheet may be adhered thereon for surface protection.

[0011]

According to the present invention, a rib groove is formed in the peripheral portion of the fiber molded plate to prevent warpage in the vertical and horizontal directions, so that the work of bonding the fiber molded plate to the core material as a face material can be easily performed. can also occur in the displacement between the surface material and the core material, the occurrence of cracks and breakage may be reliably prevented, also the rib grooves cutting La
Both measure of in-ing.
