Description

[Detailed Description of the Invention] The present invention relates to a surrounding edge for a building board used for bathroom interior materials, etc.

Conventionally, as shown in FIG. 1, bathroom interior materials 4 (
The surrounding edge A used for the interior material (hereinafter abbreviated as interior material) is made by pressing down the back surface of the interior material 4 inserted into the surrounding edge A by the tongue piece 1 provided inside the horizontal piece 3 that contacts the field edge 5. Therefore, there is no gap on the front side of the interior material 4, but a gap is created between the back surface of the interior material 4 and the field edge 5, so the part near the outer edge of the interior material 4 is bent downward from the center of the interior material 4. There was a problem with the appearance.

The circumferential edge A without the folded tongue piece 1 cannot absorb variations in the thickness of the interior material 4 and the interior material 4 is not fixed, so in some cases a gap may be formed between the surface of the interior material 4 and the circumferential edge A. There were drawbacks such as the appearance of the product being damaged.

The present invention was developed in view of the above-mentioned drawbacks of the conventional art, and its purpose is to maintain the appearance of building boards, such as interior materials, without creating gaps at the fitting part with the surrounding edges, even if the thickness of the building board is uneven. To provide a surrounding edge for a building board that does not damage it.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Figures 2 and 3, the upper and lower horizontal pieces 2 and 3 are extended from the upper and lower ends of the vertical piece, respectively, and the horizontal piece 2Q is turned inward at the tip of the horizontal piece 2Q opposite to the field edge 5 of the main body with a substantially U-shaped cross section. By extending the slightly curved tongue piece 1 inwardly and upwardly, the surrounding edge A for a building board of the present invention is obtained.

Next, the back side of the construction edge A of the present invention is in contact with the wall 6 and the upper horizontal piece 3 is in contact with the field edge 5, and the tongue piece 1 of the lower horizontal piece 2 is directed upward to touch the surface of the interior material 4. Insert the outer edge of the interior material 4 into the inner side of the surrounding edge A with the interior facing downward.

In this way, the interior material 4 is pushed up by the housing in contact with the field edge 5 by the elasticity of the tongue piece 1 which is slightly curved inward and extends upward at the tip of the horizontal piece 2 below the surrounding edge A. The tip of the piece 1 is strongly pressed against the surface of the interior material 4.

In addition, water droplets due to condensation on the surface (lower surface) of the interior material 4 flow along the outer surface of the tongue piece 1 and then flow or fall along the tip edge of the horizontal piece 2, so that the wall 6 is not soiled. do not have.

In addition, there is an upper horizontal piece 3 at the outer tip of the tongue piece 1 on the surrounding edge.
If an organic polymer elastic body B such as soft vinyl chloride or rubber is attached to the inner side of the interior material 4 or to both of them at the same time, the airtightness between the interior material 4 and the surrounding edge A will be further improved.

Furthermore, if the tongue piece 1 can be bent, the interior material 4 can be easily installed with a slope such as one-sided flow.

As described above, the present invention has a tongue piece extending inwardly and upwardly from the tip of the sewage half piece of the circumferential binding body, which has a substantially U-shaped cross section with the upper and lower horizontal pieces extending from the upper and lower ends of the vertical piece, respectively. The interior material is inserted between the tip of the sewage half and the water half of the sewage body, and the tip of the tongue that extends inward and upward from the tip of the sewage half and the edge of the sewage body. Since the interior material is inserted between the top and bottom pieces, when inserting the interior material, the interior material will fit smoothly due to the guiding effect of the tongue pieces that extend inward and upward. It has the advantage that the elasticity of the tongue allows the interior material to be firmly fixed regardless of variations in the thickness of the interior material, and the airtightness of the rotation can be easily improved. bottom surface)
Water droplets due to condensation will flow along the outer surface of the tongue and flow or fall along the tip edge of the sewage half, so it will not stain the wall surface, and the tongue will turn inwards and upwards. Since the tongue piece is extended, the tip of the tongue piece locks onto the interior material to prevent the interior material from coming off, and has the advantage that it can be securely fixed so that the interior material does not easily come off.
