Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to an improvement of the corner structure of the decorative part of a rammer having a combination structure.

B. Conventional technology Traditionally, the production of rammers by engraving a single plate is a manual process using special skills, which makes mass production difficult.The labor and manufacturing time involved are large, resulting in high prices. is used because it is suitable for mass production and is relatively inexpensive, but when the decorative part is buried in the rammer board, the four corners must be covered with outer frame material, or square, circular, etc. Although it is covered with a material, the shape of the corner is monotonous and tasteless, and it is difficult to adapt to changes in the shape of the corner of the decorative part, so if the corner is stepped etc. Since the shape was covered with an outer layer, the appearance was dull and the process was tasteless.

C. Problems to be solved by the invention In conventional corner-treated parts such as square or corner-edged parts, the appearance after treatment is monotonous and tasteless, and the shape of the corner changes as the decoration changes. Correspondingly, there were problems such as defects in the outer cover, and there was a desire for an improved corner treatment that would absorb some changes in shape and give an attractive appearance.

D. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention aims to solve the above-mentioned problems by providing a decorative lattice section that is buried in the center of the rammer board and has a height that slightly protrudes from the surface. By connecting the side ends of the acute-angled protrusion formed by one side end surface protruding toward the center of the fan-shaped circular arc and the inner circular arc, the extension lines of the two circular arcs intersect. A step portion capable of receiving the corner of the decorative lattice portion is formed on the inner and lower surfaces of the pair of half-shaped decorative members to cover the corner surface, and the other side end surface of the half-shaped decorative member is decorated. It is an object of the present invention to provide a corner structure of a rammer decorative lattice part that is continuously bonded to the outer edge frame material of the lattice part and serves as a decorative member.

E. Embodiments Next, the present invention will be further explained in detail based on embodiments shown in the accompanying drawings.

In FIGS. 1 and 2, 1 is a rammer board, 2 is a decorative lattice part embedded in the rammer board 1, 3 is the corner part of the four corners of the decorative lattice part 2, and 4 and 4' are the corner parts. The half-shaped decorative member shown in FIG. That is, the rammer board 1 is made of a wooden board, a plastic board, a metal plate, etc., and has a space in the center in which the decorative lattice part 2 is embedded, and the decorative lattice part 2 has two corner parts 3, 3 at the four corners. It is made by assembling lattice materials into a lattice-like pattern, and is buried in the embedding space at the center of the substrate 1. This decorative lattice part 2 is
It is thicker than the substrate 1 and has a shape slightly protruding from the surface of the substrate. The outer edge frame material 5 is also formed of the same material as the substrate 1, and is located on the buried boundary line between the substrate 1 and the decorative lattice section 2, and is interposed between the substrate 1 and the decorative lattice section 2 except for the corner portions 3, 3. It will be done.

Next, the decorative member 4a consisting of the half-split decorative members 4 and 4' that covers the corner 3 has an acute angle protrusion 6 that is delta-shaped in plan view and a fan-shaped circular arc, as shown in FIGS. 3 and 4. The part 7 has an area and shape that can cover the one corner part 3, and has a thickness that can receive the decorative lattice part 2 protruding from the substrate 1 on the surface, and the inner and lower surfaces of this member. Half-shaped decorative members 4, 4' are integrally arranged in series, each having a stepped portion 8 for receiving a corner portion 3 having a protruding height of a decorative lattice portion 2. This stepped portion 8 is formed by connecting the half-shaped decorative members 4 and 4' in a straight line in plan view as shown in FIG. is the third for each single half-shaped decorative member.
As shown in FIG. Then, the two symmetrical half-shaped decorative members 4, 4' are bonded to the substrate 1 with the side end surfaces of their acute-angled protrusions 6 connected to each other, and the corner decorative structure is formed. When the corner 3 is a right angle, the intersection angle between the connecting surface of the acute-angled protrusion 6 and each extension line of the other side is preferably set to 45 degrees. Next, the production of the half-split decorative members 4, 4' is as follows:
It is also possible to construct the acute angle protrusion 6 and the arcuate portion 7 by separately manufacturing them and then bonding them together.
It is preferable for mass production to manufacture the half-shaped decorative members 4, 4' in one piece. For example, as shown in Fig. 5, a ring-shaped plate made by cutting a pipe-shaped material into rings is prepared, and a pair of ring-shaped plates are prepared in the shape shown, that is, parts A and B in the figure are symmetrical, and parts C and D are symmetrical. Similarly, one pair can be formed, and a plurality of half-split decorative members 4, 4' can be manufactured from one link-shaped plate.

In this way, the decorative lattice part 2 provided on the rammer board 1 is installed in the space in which the decorative lattice part 2 is to be buried, with the surface thereof protruding from the surface of the board 1, with the outer edge frame material 5 interposed around the periphery, and furthermore, the corner part The lower adhesive surface 9 of the decorative member 4a formed by adhering the side end surfaces of the respective protruding parts 6 and 6 to the substrate 1 and the upper adhesive surface 10 to the decorative lattice part 2, the stepped portion 8 absorbs the step difference between the substrate 1 and the decorative grid portion 2, and the corner portion 3 is received and shielded within the stepped portion 8 as shown by broken lines in FIG. , to give a beautiful appearance.

F. Effects of the invention As described above, the present invention covers the corners of the decorative lattice part in which two half-shaped decorative members, each consisting of an acute-angled protrusion and a circular arc part and having a stepped part on the inner and lower surfaces, are connected. The stepped portions on the inner and lower surfaces accept and contain the steps at the corners of the decorative lattice portion, while also shielding the bent appearance of the corners to form neat and tasteful corners. It can also be used for single-arc corners, and combined with its mass-production method, it adds mass-productivity and craft value to the rammer.
