Description

[Detailed Description of the Invention] "Object of the Invention" (Industrial Application Field) The present invention relates to a method for forming a protrusion on the surface of a wall material, door plate, fixture top plate, or other base material. .

(Background of the Prior Art) As shown in FIG. 8, a raised part in the shape of a rectangular hill or a raised part in the shape of a band hill is formed on the surface of a door plate or the like. The purpose of this raised portion, AJ, is to create depth and shadow around it, thereby emphasizing the grandeur and depth of the door metal body. Furthermore, as shown in Fig. 9, a low embankment-like raised part is formed on the periphery of the upper surface of the counter top plate, etc., and the raised part is used to prevent objects placed on it from falling. It also gives a sense of decorative beauty.

(Problems to be Solved by the Invention) Conventionally, the following methods have been used to form raised portions, etc., on base materials such as door panels, counter top plates, etc. as described above. That is, a roughly finished core piece of the raised portion is formed using a wood board or the like as a material, the core piece is appropriately arranged and adhered to the surface of the base material, and a decorative sheet or the like is affixed to the entire surface of the base material and the core piece, It involved spraying paint. However, such work was not only extremely troublesome, but also required highly skilled processing techniques.
Those who were inexperienced in the crafting process were unable to form the ridges neatly.

The present invention has been made in view of the above circumstances, and allows even those who are inexperienced in machining to easily form ridges on the surface of a base material, and provides a beautiful finish. It is an object of the present invention to provide a novel method for forming a protuberance (hereinafter referred to as the method of the present invention).

"Structure of the Invention" (Means for Solving the Problems) The gist of the method of the present invention is to form a raised portion on the surface of a base material of a wall material, a door plate, a fixture top plate, etc. A fitting groove is carved on the surface of the base material with the planned raised part sandwiched therebetween, and a laminate for forming a raised part having a wall thickness that can be fitted into the fitting groove is selected, and the surface is formed on the backing layer of the laminated plate. A curved edge is formed by carving a curved groove or a row of curved slits in which a raised part is planned, and a raised filler material is provided between the surface of the planned raised part of the base material and the backing layer surface of the laminate. The curved edge of the laminate is fitted and fixed into the fitting groove of the base material with or without interposition.

(Function) A fitting groove is carved on the surface of the base material so as to sandwich the planned raised portion. Then, a laminate plate for forming the protuberances having a wall thickness that can be fitted into the fitting groove of the base material is selected.

In the laminate, grooves for bending or rows of slits for bending are carved on the back surface of the portion that can become the raised surface, that is, on the backing layer, in which the surface is intended to be raised. Therefore, around the laminate, a laminate with a zero bending groove in which a bending edge is formed further on the outer periphery of the bending groove or bending slit row is used to absorb the groove width. When the groove is bent in the direction shown in FIG.

In addition, when a laminate plate with a row of slits for bending is bent in a direction that accommodates the width of each slit, the bent outer surface has a radius of curvature corresponding to the width of the slit and the mutual spacing. A curved surface can be formed. In addition, in order to increase the degree of protrusion of the raised portions, it is sufficient to interpose a raised filling material such as plywood or synthetic resin between both the base material and the laminate.
Further, by adjusting the amount of the protruding filler material provided, the degree of protrusion can also be adjusted as desired. In this way, in the method of the present invention, with one extremely simple operation,
It becomes possible to form a raised portion on the surface of the base material.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a sectional view showing a base material 1 manufactured by the method of the present invention.The method of the present invention forms a raised portion 1c by attaching a laminate 3 to the surface 1a of the base material 1. .

As shown in FIG. 2, the base material 1 is a hardboard.

It is made of solid board materials such as particle board, or hollow flash materials made by pasting decorative plywood on both the front and back sides of a framework. The surface 1a of the base material 1 is covered with a decorative material N made of synthetic resin such as melamine resin, unsaturated polyester resin, diallyl phthalate resin, vinyl chloride resin, or natural wood veneer.
2 is formed. First, on the surface 1a of this base material 1, a fitting groove 1b is carved to sandwich the planned protrusion part.Although not shown, the overall groove arrangement shape in which the fitting groove 1b is carved is shown in a plane. When viewed from the outside, when the raised portion 1c has the shape of a rectangular hill shown in FIG. It becomes like this. Further, when the raised portion 1c has a bank-like shape as shown in FIG. 8, the raised portion 1c has the shape of two parallel lines that are close to each other.

The laminated plate 3 is selected to have a wall thickness slightly smaller than the groove width of the fitting groove 1b carved in the surface 1a of the base material 1. The laminate 3 is made of plywood or the like,
A decorative layer 4a having the same quality as the decorative layer 2 provided on the surface 1a of the base material 1 is backed up by a backing layer 4b made of plywood or the like. The laminated plate 3 is provided with a bending groove 5 intended for the raised surface X on the back surface of the surface X that can be a raised surface, that is, on the backing layer 4b.In this embodiment, the cross-sectional shape is M.
It shows what is engraved to form a character shape. The bending groove 5
The depth of the engraving was set to reach the depth of the decorative layer 1i4a, taking into account ease of curve formation. The laminate 3 made in this way is
If the laminated plate 3 is bent in a direction that absorbs the groove width of the curved groove 5 as shown by the arcuate arrow, curved edges 3a, which are orthogonal to the raised surface X, are formed on both side edges of the laminate 3. 3a is formed hanging down. Therefore, finally, the curved edge 3a of the laminate 3 is fitted into the fitting groove 1b of the base material 1. In this case, strong adhesive force can be obtained by applying a vinyl acetate adhesive or the like between the two.

The curved grooves 115 carved in the backing layer 4b of the laminate 3 are not limited to the M-shaped grooves as described above, but may also be angular grooves whose groove width is equal in the depth direction, as in the laminate 6 shown in FIG. i17 for music composition
In such a case, when the bending groove 7 is bent in a direction that absorbs the groove width, a virtual triangular prism-shaped space Y will be formed within the groove. A correspondingly shaped piece of wood, resin mandrel, or the like (not shown) may be inserted into the space Y to maintain the bent shape of the corner.

In addition, another method can be considered in which a synthetic resin that is still in a softened state is injected into the space Y and waits for it to harden. Furthermore, if a foamable resin is used for the injection resin,
The shape of the edge around the raised portion can be varied as shown in FIGS. 4(A) and 4(B).

FIG. 4(A) shows an example in which the edge shape is an outer radius.The method for forming the edge is as follows: thin mandrel 1
0 was inserted, and at the same time, a foamable resin 9 was injected between the space Y and the mandrel 10. Then, the arc surface 10 of the mandrel 10
A mold (not shown) having an inner radius pressing surface corresponding to a was pressed from the outer surface of the curved portion of the laminate 6 and heated. It should be noted that a raised filler material 8 made of plywood or the like is interposed between the base material 1 and the laminated board 6 so that the amount of protrusion becomes thicker. This is an example in which an inner radius portion 6a is further incorporated in a composite manner in the middle of the outer radius.

FIG. 5 shows an embodiment in which a bending slit row 13 consisting of a plurality of slits 13a, 13a, . . . is carved into the backing layer 12b of the laminate 11. It is preferable to impregnate the bending slit row 13 with an appropriate resin for reinforcement.In this embodiment, the fitting groove 1b of the base material 1 is placed at the center of the planned raised portion. part, that is, the laminate 11
The laminate 1 is tilted inward toward the base material 1.
This is to increase the adhesive strength of No. 1.

In the embodiment shown in FIG. 6, contrary to the embodiment described above, the fitting groove 1b of the base material 1 is located at the outer peripheral portion of the planned raised portion, that is, in the laminate 14.
In this embodiment, the curved edges 14a, 14a of the laminate 14 are connected to the fitting groove 1b of the base material 1 in order to improve the adhesive strength.

1b, but if a row of bending slits (not shown) at an appropriate pitch are carved on the backing layer 14b of the laminate 14 over the entire surface, the line 1b will be slightly difficult to fit into the backing layer 14b. As shown in FIG. Bye.

(Study of Alternative Embodiments) In addition to the many embodiments described above, it is conceivable to use a plurality of laminated plates to form the protrusions in a stair-like manner. Furthermore, the bank-like raised portions shown in FIG. 9 can also be formed as shown in FIGS. 7(A) to (C), and the raised surfaces can be made into flat surfaces. As described above, the detailed configuration of the method of the present invention can be changed as appropriate depending on the implementation mode, without being limited thereto.

"Effects of the Invention" As is clear from the above explanation, according to the method for forming ridges on the surface of a base material according to the present invention, even a person who is inexperienced in machining can form ridges on the surface of the base material. Not only is it possible to do this, but it also has many excellent advantages, such as being extremely easy to work with and producing a beautiful finish.
