Description

[Detailed Description of the Invention] The present invention relates to a edging material used as a parting material or a corner material, and its purpose is to provide one type of edging material that can be used in various places.

Traditionally, parting materials and corner materials used for the joints of wall materials constructed inside houses, and for the separation between pillars and wall materials, floor materials, ceiling materials, etc., were carved out of solid wood. However, they had the disadvantage of being time-consuming to prepare and wasting materials.

Therefore, in recent years, extrusion molded products of synthetic resin and metals such as aluminum have been used relatively frequently, and these come in various shapes such as for external corners, internal corners, surrounding edges, and partings. Each item is provided as a single item, and it is not the same shape that can be used for various purposes, and because it is made with thin walls to reduce weight and cost, it does not easily deform or change shape. It had problems such as breakage and was difficult to use.

The present invention has been made in view of the above-mentioned conventional drawbacks. That is, in the present invention, a decorative sheet is attached to the surface of the substrate to form a decorative substrate, three V-grooves parallel to the sides of the decorative substrate are provided at predetermined locations on the back surface of the decorative substrate, and further, three V-grooves are provided on the back surface of the decorative substrate. In a substantially square-shaped cross-section having a bent side portion formed by bending and bonding from a V groove, one bent side portion protrudes from the other bent side portion by a dimension equal to the thickness of the decorative substrate. , and the edge material is characterized in that both bent side portions have an interval of equal size to the thickness of the decorative substrate. Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a sectional view of a edging material according to an embodiment of the present invention. The substrate 1 is a commonly used wooden substrate such as plywood, pateboard, hardboard, MDF, etc. with a thickness of about 4 to 20 mm, and a decorative sheet 2 is adhered to the surface thereof. As the decorative sheet 2, a single or composite material such as a synthetic resin film such as vinyl chloride resin, synthetic paper, paper, cloth, nonwoven fabric, veneer, etc. is used. As shown in FIG. 2, three V-grooves parallel to the sides of the decorative substrate are provided at predetermined locations on the back surface of the decorative substrate having the above structure. In this embodiment, in order to prevent the bent portion from becoming angular, a small convex portion 6 is provided inside the V-groove 4, and a tapered portion that looks like a chamfer is formed.

One bent side edge 7 forming the edge material has a dimension a equal to the decorative substrate thickness a than the other bent side edge 8.
In addition, the bent side portions 7 and 8 are spaced apart by a dimension a equal to the thickness of the decorative substrate.

Next, a method of using the edge material having the above structure will be explained.

Figures 3 to 5 show general usage examples of the edge material of the present invention. Figures 3 to 4 show its use as a parting material when constructing a wall surface, and Figure 5 shows its use as a border around a ceiling. This is when used as a material.

FIG. 6 shows an example of use in which the present invention is most distinctive, in which two edge materials are combined and used like a decorative pillar. In other words, one bent side of the edge material is made to protrude from the other bent side by a dimension equal to the thickness of the decorative substrate, and both bent sides are spaced apart by a dimension equal to the thickness of the decorative substrate. Because there is
It is possible to combine two edge members having the same shape by facing each other and firmly fitting them together without any gaps.

In the figure, 9 is a column, 10 is a horizontal rim, 11 is a vertical rim, 12 is a wall material, 13 is a nail, and 14 is a ceiling material.

As mentioned above, one type of the edging material of the present invention can be used for various purposes, and since the nailed part can be covered with a wall material such as a decorative board, beautiful construction can be achieved. Also, unlike those carved from wood,
Since it is made of plywood or other base material with little distortion, it can be mass-produced without warping, twisting, or other distortions, and therefore it is possible to supply edge materials with stable quality at a low cost.

Furthermore, compared to conventional products, there is almost no processing required at the work site and the decorative sheet is pasted in advance, eliminating the need for painting at the work site and improving construction efficiency. Furthermore, since the edge material of the present invention has an opening with the same dimensions as the thickness of the decorative substrate, it has the effect that even if the edge materials are combined with each other and used as a decorative column, they can be firmly combined without any gaps. .
