Description

[Detailed Description of the Invention] Industrial field of application The present invention is an unexpected situation or mischief when the wall covering material attached to the wall surface by the attractive force of a magnet is used in a place such as an elevator where many unspecified people use it. The present invention relates to a seam covering material for a wall covering material, which can effectively prevent the edge portion of the wall covering material from peeling off.

2. Description of the Related Art Conventionally, in order to make a seam of a wall covering material attached to a wall surface inconspicuous by magnetic force, a means such as bringing them into close contact with each other or matching a pattern has been adopted.

Problems to be Solved by the Invention Conventionally, even if the seams, that is, the joints are made inconspicuous by the above-mentioned means, the magnet sheet used for the wall covering is affected by the room temperature, etc. There is a limit to making the seam of the wall covering material attracted by the magnet inconspicuous because it expands and contracts in the feeding direction at that time, and a gap or a doublet may occur at the seam. Therefore, it is possible to cover the seam itself, but since the wall covering material is fixed by the attraction of the magnet, if the wall surface and the wall covering material come into contact during the sticking work, they are adsorbed at that position and the The wall covering cannot be slid along the wall as it would be if the seam was covered with a H-shaped cross-section fitting. Therefore, the conventional product used for the veneer plate or the like for the joint covering of the wall covering material stuck by the magnet cannot be used, and there is no suitable joint covering part.

The present invention does not make the seam inconspicuous in the entire surface of the wall, but also tries to positively incorporate the seam into a part of the decoration so that the end of the seam is not exposed.

Means for Solving the Problems In order to achieve the above object, the seam covering material of the wall covering material according to the present invention has a plurality of wall covering materials having a magnetized surface on one side and a decorative surface on the other side. Affixed to the wall surface of the magnetic material, for example, an ultra-thin film made of ultra-thin synthetic resin, steel foil, and a magnet sheet and having a fitting base in the central longitudinal direction. It is configured by interposing and fixing between the mounting materials, and connecting the fitting portion provided on the back surface of the long covering piece and the fitting base portion.

Effect Since the present invention adopts the above-mentioned configuration, since the edge of the wall covering once attached to the wall is not exposed, it can be peeled off even if external force is applied due to mischief or an unexpected act. Even if the magnet sheet slightly expands or contracts due to aging, it can be absorbed while being covered with the long covering piece, and a beautiful appearance can be maintained.

Example 1 is a long covering piece having a substantially T-shaped cross section, which is made of a synthetic resin and is subjected to a decorative treatment such as a pattern or coloring on the surface side. Reference numeral 2 denotes a fitting base made of synthetic resin, which is fitted to the back surface side of the long covering piece 1 to form a concave-convex fitting portion 3. Reference numeral 4 is an ultrathin film having a pressure-sensitive adhesive layer or an adhesive layer on the back surface, which is made of synthetic resin. The ultra-thin film 4 has the fitting base 2 fixed in the central longitudinal direction. Reference numeral 5 denotes a wall surface having a surface made of a magnetic material, 6 denotes a wall covering material having a magnetized surface on one surface side and a decorative surface on the other surface side, which is attached to the wall surface 5 by magnetic force. Both side edges of the ultrathin film 4 are adhered along the end edge portion of the wall covering material 6 by interposing between the wall covering material 6 and the wall surface 5, and the seam is covered with the long covering piece 1.

That is, at the edge portion of the wall covering material 6, the ultrathin film 4 to which the fitting base portion 2 is fixed is adhered to the wall surface in advance, and the end portion of the wall covering material 6 is adhered thereto. After that, the long covering piece 1 is fitted to the fitting base 2 to completely cover the seam of the wall covering material 6.

The ultra-thin film is not limited to synthetic resin, for example, a thickness of about 0.03
A steel foil having a thickness of about 0.1 mm or a magnet sheet having a thickness of about 0.1 mm to 0.3 mm may be used. When steel foil or magnet sheet is used as the ultra-thin film, it can be attached to the wall surface by magnetic force without using an adhesive, and since the ultra-thin film can be easily attached and detached, the seam part can be attached even after attaching the wall covering material. It is possible to correct the dimensional error in.

FIG. 3 and FIG. 4 show an embodiment of the entrance corner and the exit corner. The decorative surface of the long covering piece may be a flat surface instead of a curved surface depending on the installation location.

In the above embodiment, the concave-convex fitting portion is composed of a long groove formed from one end of the long covering piece in the longitudinal direction to the other end and a convex portion, or a plurality of concave-convex fitting portions are formed along the longitudinal direction. In some cases

Effect of the Invention As described above, the present invention does not expose the edges of the wall coverings located at the corners or joints of the elevator or room,
There is no risk of peeling due to accidents or mischief when the wall covering is attached, and even if the magnet sheet expands or contracts due to room temperature after the wall covering is attached, the amount of expansion and contraction is covered with a long covering piece. The effect is that it can be absorbed within the specified range, the appearance at the time of mounting the wall covering material can be maintained for a long time, and the life of the decorated wall surface can be extended.
