JPS6041142Y2 - Table board with a sheet pasted on the decorative edge - Google Patents

Description

[Detailed description of the invention] The present invention relates to a table board for use as a top board for a kotatsu or a table for play, and in particular covers a flexible cloth or leather-like sheet along the decorative edge of the outer periphery, and This relates to a table board with facing materials attached to both sides.

In general, this type of table board has a central flat part made of plywood and a face material, and the decorative edges are made of high-quality wood or synthetic resin and are fixed by fitting to the side edges of the flat part. There is.

In the case of decorative edges of wood, the finishing process involves repeated circumferential cutting, sanding, masking, painting, regrinding, and repainting, requiring time for drying and solvent release between each process. .

The fitting between one side of the decorative edge and the adjacent side and between the decorative edge and the flat portion requires high-precision machining in order to ensure firm fixation by fitting the uneven portions.

When a molded decorative edge made of synthetic resin is used, the decorative edge itself can be easily processed, but there are disadvantages in that gaps are created due to shrinkage due to temperature changes, and the driving foot is likely to come off due to shock.

In the case of decorative edges made of extruded metal edge material whose ends are bitten into the plywood, the joints with the flat parts may break in a short period of time, and the heat transfer rate is high. The disadvantage is that it does not feel good in the hand.

Additionally, there is generally a risk that the joint between the decorative edge and the flat portion may separate due to distortion or impact during drying.

Thus, for many of the reasons mentioned above, this type of tabletop board has not become widely popular despite its practicality.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an improved table board that facilitates the processing of decorative edges, improves the texture, and prevents damage to joints.

The feature of this invention is that the flat part and the decorative edge of the table board are formed into an integrated plate-like body, and a flexible cloth or leather-like sheet is covered along the decorative edge to improve the feel of the table board. The beauty of the object is enhanced by attaching a surface material to the front and back surfaces of the object.

The structure of the table board of the present invention is that continuous rectangular grooves are carved near the peripheral edges of the front and back surfaces of the plate-shaped body, and each peripheral edge of the plate-shaped body is cut into a protruding smooth cross section. death,
“A cut groove extending in the diagonal direction of the plate-like body is cut in each corner, a band-shaped sheet is wrapped along the peripheral edge, and the end or middle portion of the sheet is cut in each corner. By pushing the sheet into the cut groove, the sheet is adhesively fixed while absorbing the wrinkles that inevitably occur at the corners when the sheet is wound, and the side edges of the sheet are further inserted into the groove. It is formed by inserting and fixing with adhesive, and then attaching face materials to the front and back surfaces of the plate-like body, respectively, so as to cover the side edges of the sheet.

Machining of the outer periphery of the decorative edge and machining of the concave grooves and cut grooves are prohibited.
This can be done with high precision using a router board or profile chamfering board.

The surface material is preferably made of synthetic resin such as melamine resin or melton cloth.

Other features and advantages of the table board of the present invention will become clearer from the following description of the embodiments.

FIG. 1 shows one embodiment of the table board according to the present invention, in which a melton cloth face material 14 is attached to the center of the surface of the table board 10, and a leather-like sheet 12 is covered on the decorative edge. has been done.

At each corner 21° 22, 23, 24, the sheet 12
The end or middle portion of the cut groove is pushed into the groove and fixed with adhesive.

As shown in cross section in FIG. 2, the main part of the table board 10 is integrally formed with a plate-like body 18, and a melamine resin board 16 is attached to the center of the back surface.

As shown in FIGS. 3 and 4, the plate-shaped body 18 is produced by processing a plate-shaped material 34 using a router board or a chamfering machine, and forming continuous rectangular recesses near the peripheral edges of the front and back surfaces. Groove 26.2
8, each peripheral edge E is cut into a protruding smooth cross-sectional shape, and each corner C is formed by cutting a cut groove 30 extending in the diagonal direction of the plate-shaped body.

The band-shaped sheet 12 is wrapped along the peripheral edge E, and the end or middle portion is pushed into the cut groove 30 and fixed with adhesive as shown in FIG. 2, and then A and B in FIG. As shown in the section, its side edges are inserted into the grooves 26, 28 and fixed with adhesive.

Thereafter, face materials 14 and 16 are attached to the front and back surfaces of the plate-like body 18, respectively, so as to cover the side edges of the sheet 12, thereby completing the table board 12.

Another embodiment shown in FIG. 5 is an example in which the protruding portion of the plate-shaped body 18 is made of plywood structure 36 in order to reduce the cutting allowance during cutting, and the material in this case is as shown at 38. Significant material savings can be made.

Further, it is desirable that the width of the groove portions 26 and 28 is changed depending on the thickness and material of the sheet or face material.

As mentioned above, the table board of the present invention has many advantages based on its unique structure as follows.

(I) The manufacturing process is greatly simplified.

(II) The decorative edge has an excellent texture and is particularly suitable for use in hot or cold environments.

(III) By selecting the sheet, it is possible to freely select various aesthetics that cannot be obtained by painting.

(IV) By replacing the sheet, cleanliness can be maintained and the design can be changed.

(V) The plate-like body does not become distorted or peeled off due to changes over time.

(VI) Since no painting process is required, it is possible to prevent adverse effects on the environment and the human body due to paint diffusion.

The table board obtained by the present invention has many excellent properties as mentioned above, and its practical value is remarkable.
