Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a storage door, that is, a door for use in furniture or other storage devices.

Conventionally, most storage doors have been flat, while those with a slightly three-dimensional shape have been made by cutting natural wood boards or molded from synthetic resin.

However, in the case of the former, although it is three-dimensional, it is more like a planar shape, requiring considerable labor to manufacture, high material costs, and no ingenuity in its design.

Furthermore, since most three-dimensional items were handmade by hammer craftsmen, it was difficult to process them and an increase in costs was unavoidable.

In the latter case, it is possible to obtain a door with a richer three-dimensional effect than the former, but it is difficult to harmonize with furniture made of wood-based materials and lacks dignity.

However, there is a strong demand for three-dimensional and interesting doors, and while doors for storage items need to be luxurious and have excellent design, they also need to be lightweight.

Moreover, in order to reduce manufacturing costs, even in the case of a door with a height of 180 crIL, for example, without using special machinery and equipment, in the manufacturing process,
It must be extremely easy to manufacture even by unskilled workers.

The present invention was made in view of the above circumstances, and is lightweight and durable without cracking, twisting, or warping by using a wood-based material, and is formed by using a peeled board of natural wood. To provide a manufacturing method for easily obtaining a door for a storage device that has an appearance similar to that of a decorative board, has uneven surfaces of various shapes, has a three-dimensional effect, and has a variety of designs. It is.

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIG. 1 shows a decorative door 1 for storage tools according to an embodiment of the present invention, in which a decorative board material 2 is attached to a substrate 4 connected to a frame member 3 as shown in FIG. It will be done.

The decorative board material 2 is made of a plywood-type base plate 5a and a board material 5, which is made of natural wood veneer or the like as a surface material 5b, and is bonded together at an angle to form convex portions 6 and four portions 7 continuously and alternately. It becomes.

A plywood substrate 4 is adhered to the back surface of the concave portion 7 of the decorative board material 2 and integrated, and a hollow portion 8 is formed between the convex portion 6 having a trapezoidal cross section and the substrate 4 portion.

The rectangular decorative board material 2 is fixed to the frame member 3 at the peripheral end 4a of the substrate 4 to which it is not attached.

Next, a method for manufacturing the vanity door of the storage device will be explained.

First, as shown in Fig. 3, a flexible and durable material such as paper tape or cloth tape is applied to the surface of the board material 5, which is made by laminating and bonding a natural wood veneer or the like as the surface material 5b on the surface of the plywood base plate 5a. The flexible sheets 9 are pasted in advance, and the flexible sheets 9 are attached from the back surface 5' of the plate material 5 in correspondence with these flexible sheets 9.
V-shaped notch grooves 1Qa and 10b are provided in parallel so as to reach the back surface of the flexible sheet 9 but not to damage it.

The flexible sheet 9 may be attached only to the portions where the cutout grooves 1Qa and 10b are formed, or may be attached to the surface of the plate material 5.

Notch groove 10a. 10b is the notch groove 10a as described later.

The shape of the convex part 6 and the concave part 7 obtained by bending 10b,
The width, height, etc. are determined, and the notch groove 10a.

The angle θ formed by the valley 10b is set corresponding to the bending angle of the convex portion 6 and the concave portion 7.

Further, notch grooves (not shown) may be provided with a depth such that the groove bottoms of the notch grooves 10a and 10b do not reach the surface of the surface material 5b.

With this depth, the notched groove portion will not be scratched on the outer surface of the decorative board material.

Using the flexible sheet 9 as a guide, the plate material 5 is bent so as to close the notch groove 10a at the notch groove 10a,
A trapezoidal convex portion 6 is formed by bonding each of them, and a recess 7 is formed by expanding the notch groove 10b into a planar shape at the other notch groove 10b using the flexible sheet 9 as a guide. A series of decorative board materials 2 are formed in which convex portions 6 and concave portions 7 are continuously and alternately formed.

Next, the notched groove 10b which is widened in a planar manner is arranged on the substrate 4 and bonded, and then the flexible sheet 9 is removed from the surface of the plate material 5, so that the substrate 4 as shown in FIG. 4 is pasted. The applied decorative board material 2 is formed.

In addition, when bending the plate material 5 with the cutout grooves 10a and 10b using the flexible sheet 9 as a guide, as shown in FIG. Once fitted, the protrusions 6 and recesses 7 can be formed accurately and quickly.

The inner bottom surface of the female mold 11 is formed with a groove 12 so as to form an uneven pattern that is opposite to the protrusions 6 and recesses 7 as shown in FIG. A convex portion 6 and a concave portion 7 are formed.

Furthermore, when the plate material 5 is fitted into the female die 11, the decorative plate material 2 can be attached to the substrate 4 by overlapping the substrate 4, fitting the flat male die 13, and applying pressure.

The groove 12 formed on the inner bottom surface of the female mold 11 is changed as appropriate depending on the desired projections 6 and recesses 7 of the decorative board material 2.

Next, the frame member 3 will be described.

As shown in FIG. 2, the frame member 3 has a surface plate 3a made of the same material as the decorative board material 2 and having a substantially trapezoidal cross section, butted together at an angle, and has a polygonal cross section on the back side of the butted area. It is attached to the outer peripheral surface of the core material 3b so as to come into contact with the corner of the core material 3b made of a wood-based material such as wood, and the surface plate 3a is not attached to a part of the inner side of the back surface of the outer peripheral surface of the core material 3a. The top plate 3a is attached so as to be exposed, and the core material 3b to which the top plate 3a is attached is bonded together in a frame shape.

Note that the frame member 3 is not limited to the one described above, and may be a frame member 31 that is chamfered as shown in FIG. 7, for example.

Then, the substrate 4 to which the decorative board material 2 is attached is attached to the decorative board material 2.
At the peripheral end 4a to which the frame member 3 is not attached,
If the frame member 3 and the base plate 4 are connected to each other on the inner side of the back surface of the core material, which is the part to which the surface plate 3a is not attached, the present storage device vanity door is completed.

Note that the decorative board material 2, frame member 3, and substrate 4 are not limited to those described above, and for example, in addition to the upper part, particle board, fiber board, asbestos board, wood board, etc. can be used.

The shapes of the convex portions 6 and the concave portions 7 can also be changed as appropriate by changing the angle at which the plate materials 5 are butt-bonded as described above.

For example, as shown in FIGS. 7 and 8, the protrusions 5a and 6b may have triangular cross sections.

Furthermore, in the embodiment shown in FIG. 1, the protrusions of the protrusions 6 of the decorative board material 2 are formed in the horizontal direction, but as shown in FIG. 9, the protrusions of the protrusions 6/ are formed in the vertical direction. It may be formed as follows.

In addition, as shown in Figure 10A, triangular decorative board material 2
a and 2b are butted and glued together to form a convex portion 6c and a concave portion 7.
It may also be used in such a way that a is connected in an angular ring shape.

By joining decorative laminates in a plane as shown in FIG. 10A, various decorative laminates can be made.

For example, a combination of a triangular decorative laminate material and a trapezoidal decorative laminate material as shown in the opening in Figure 10, a combination of square decorative laminate materials as shown in Figure 10 C to E, or a convex part in addition to a square annular shape. Various changes can be made by changing the connections.

In this case, only the decorative board material may have a predetermined shape, for example, a triangular shape, or both the substrates may have a predetermined shape.

The storage device vanity door according to the present invention may be used as a door for furniture or other storage devices in the same way as a normal door.

For example, as shown in FIG. 1, it may be attached using a hinge or the like.

As described above, the present invention adheres a flexible sheet to the surface of a board material, arranges notch grooves in parallel from the ground surface of the board material, and bends the board material using the flexible sheet as a guide to form the notch grooves. The manufacturing method is extremely easy because the decorative board material is obtained by closing or opening the lid, the substrate is adhered to the decorative board material, and the frame member is connected to the decorative board material.

Further, since it is manufactured by fitting a plate material with parallel notch grooves into a female mold having grooves on the inner bottom surface and attaching the substrate to the plate material, it can be manufactured more accurately and easily.

In other words, instead of the traditional method of carefully manufacturing each piece by a skilled joiner, a female mold of a mold corresponding to the convex and recessed parts of the decorative board is prepared, and a mold for the decorative board is placed in the female mold. Decorative laminates are manufactured by inserting plates with approximately trapezoidal cross-sections and gluing them together. At that time, flexible sheets are also used as guide materials, making it possible to create complex structures that previously could only be done by skilled workers. This made it possible for even amateurs to easily manufacture doors, thereby reducing manufacturing costs.

In addition, since the flexible sheet is attached to the plate material in advance, even if the plate material is bent at the notch groove, the plate material will have appropriate flexibility, so cracks will not occur on the surface of the plate material. This can be prevented and the appearance of decorative board materials becomes beautiful.

As the surface plate of board materials and frame members, manufacturing costs are low because natural wood veneers are bonded to plywood, and in terms of durability, they are free from shrinkage, expansion, cracking, twisting, etc. This is excellent because it allows the use of plywood, etc., which has less warpage.

However, because there are many hollow parts, it is possible to obtain an extremely lightweight door, which makes it easy to open and close the door, and the hinges and other parts that attach the door have excellent durability.

Furthermore, since natural wood appears on the outer surface of the decorative laminate and frame members, it is possible to obtain a luxurious appearance that is no different from that of a wood board that has been cut. If the same material is used as the face plate,
It is possible to unify the design of the door.

In addition, various uneven surfaces can be formed and the bonding relationship of the decorative board materials can also be changed, so it is possible to create a door for storage utensils with a rich variety of three-dimensional effects.

In addition, since the peripheral edge of the substrate to which the decorative board material is not attached is adhered to the stepped portion on the inside of the back surface of the frame member to which the surface plate is not attached, the frame member and the substrate are connected to each other. A strong connection can be achieved simply by gluing the board and frame member together, and there is no level difference between the board and frame member on the back of the door.
It is possible to obtain a smooth door, and it is extremely convenient because it does not collect dust or the like.

The present invention has various excellent effects as described above.
