Description

[Detailed description of the invention] This invention is based on the front side of the main body part of a plate-like body, which is composed of a hollow front plate with a void inside and a decorative sheet pasted on the front side, and a substrate with a decorative sheet pasted on the back side. Several vertical parallel Vs on both left and right sides or on one side
By tightly fitting and adhering the ends of the face edge frame, which is formed to be bendable through the groove, to both sides or one side of the hollow face plate, it can be attached to both sides or one side edge of the main body portion of the plate-shaped body. This invention relates to a plate-like body having a face edge formed integrally with a bar-shaped face edge.

The purpose of the present invention is to simultaneously form a frame material and a facing material for fittings, door materials, doors of living furniture, etc., into a plate-like body.
In order to form a plate-like body suitable for doors of residential furniture, etc.
The most common types of doors are the flush structure with a frame or frame inside, or the panel door where the frame is attached to a plate-like panel.In both cases of a flush structure and a panel door, the frame and frame are made in separate processes, and the frames and frame are made in separate processes. It requires a joint structure such as dowels and notch fitting to attach it, which not only complicates the manufacturing process, but also tends to cause warping and other deformations due to the use of different materials. There were many problems such as strength.

The present invention was devised to solve these problems, and the gist of the present invention is to provide a V-cuttable plate body with a bendable decorative sheet attached to the back side. A portion of a predetermined width corresponding to both left and right sides or one side of the part is set as a portion to be a surface edge, and this portion to be a surface edge is cut into a substrate through a vertically parallel V groove formed by cutting the substrate. The main part of the plate-like body can be bent freely toward the surface side, and the parts that should become the surface edges include a side surface edge stile, a pair of left and right corner side edges sills, and an intermediate section between them. The front side edge stile and the square edge stile engaging square portion are sequentially connected laterally via vertically and horizontally oriented V-grooves so as to be bendable, and have a predetermined width corresponding to both sides of the plate-like portion of the board. A hollow surface plate with a decorative sheet pasted is fixedly provided on the surface of the main body portion of the plate-shaped body, and further, in the portion that should be the back side of the surface edge, A recessed groove for fitting and adhering the end of the face edge stile is bored on the side that is in close contact with the hollow surface plate side, and the rectangular part for engaging the face edge stile is folded into this groove and is fitted and adhered thereto; The present invention resides in the structure of a plate-like body having a bar-shaped face edge formed integrally with both side edges or one side edge of the main body portion of the plate-like body.

The decorative sheet used in the present invention is a plastic sheet with a printed pattern or a laminated decorative sheet such as a plastic printed sheet adhered to a particle board, and the substrate is wooden plywood, chipboard, or the like. The hollow surface board may have the same structure as so-called corrugated paper, in which a continuous corrugated curved sheet is inserted between the front and back boards, or a distance-retaining material such as the same square timber may be inserted at an appropriate interval between the front and back boards. An appropriate type, such as one with an inserted flash structure, can be used.

Next, the present invention will be explained with reference to an embodiment shown in the drawings. As shown in FIG. Portions of a predetermined width corresponding to both left and right sides of the plate-shaped body main body portion a are defined as portions b, b which are to become the surface edges.

The portions b and b which are to become the surface edges are formed so as to be bendable toward the surface side of the plate-like main body portion a of the substrate 2 via vertically parallel V grooves 3 cut into the substrate 2.

Next, in the parts b and b that should become the face edge, a side face edge stile 4, a pair of left and right corner face edge stile 5, 6, a middle surface side edge stile 7, and a face edge stile for engaging the face edge stile. The rectangular portion 8 is formed by vertically parallel V grooves 9, 10, 1, respectively.
1 and 12 in a bendable manner.

Further, portions of a predetermined width on both sides of the plate-like body portion a of the substrate 2 are portions c that should be on the back side of the surface edge,
c, and on both sides of the plate-like main body portion a of this substrate 2, the portions c that should be the back side of the surface edge, overlap the surface side of the portion that corresponds to the inside of c, and a void d is formed inside.
In addition, a hollow surface plate 14 having a decorative sheet 1 adhered to the surface side is fixed by adhesive or the like.

In the portion c that should be the back side of the surface edge, there is an adhesive reservoir 16 on the side that is in close contact with the hollow surface plate 14 side.
A concave groove 15 for fitting and bonding the surface edge frame end is bored,
The end portion of the square portion 8 for engaging the surface edge stile is folded into the groove 15, and is fitted and bonded. e is an adhesive.

As the hollow surface plate 14, between the front and back plates,
A so-called corrugated paper structure in which a continuous corrugated curved sheet is inserted in the middle, as shown in the cross-sectional view of FIG. Alternatively, as shown in the sectional view of FIG. 3, an appropriate distance-keeping material may be used, such as one with a flash structure in which square pieces are inserted at appropriate intervals.

In order to assemble the plate-like body of the present invention from the face material formed as described above, as shown in FIG.
4 are glued and fixed, and then the side face edge stile 4, the corner face edge stile 5, 6, the front side edge stile 7, and the square edge stile engagement square part 8 of the portion b which is to become the face edge on both sides are attached respectively. Bend it along the V-grooves 3, 9, 10, 11, and 12 so that the part c that should be the back side of the face edge is located on the back side thereof, and then bend the end of the square edge stile engagement square part 8. As shown in FIG. 4, it is fitted into the face edge frame end fitting adhesive groove 15 and fixed by adhesive using the adhesive e supplied to the adhesive reservoir 16. It is possible to assemble the plate-shaped body of the present invention in which rod-shaped face edges f, f are integrally formed on both side edges of the plate-shaped body main body portion shown in the figure.

The present invention has been described in terms of a structure in which rod-shaped face edges f, f are formed on both the left and right sides of the plate-like body part a, but in some cases, on one side edge of the plate-like body part, A similar bar-shaped surface edge f can also be formed. In this case, the portion that should become the edge of the other side is cut off, leaving that side as a flat plate.

According to the present invention, a face edge stile is formed by cutting a V-groove on both side edges or one side edge of a plate-shaped body with a front and back decoration with a gap in the middle, and is then bent along the V-groove and bonded. By fixing, it is possible to integrally form a bar-shaped edge on the side edge of the plate-shaped body, and through an extremely simple process, it is possible to produce fittings, door materials, etc. that have a good appearance, are light in weight, and have a uniform edge. This has the effect of economically providing a plate-like body with a surface edge suitable for applications such as doors of household furniture.
