Description

[Detailed explanation of the invention] [Industrial application field] This invention is a method of fixing the projecting corners of walls and columns in rooms such as ordinary houses and condominiums by abutting against them and reinforcing the projecting corners. The present invention relates to a reinforcing material that protects this material in a beautiful manner.

[Conventional technology]

Among various building materials, gypsum board is lightweight, easy to handle and process, and has excellent fire resistance, heat insulation, and sound insulation properties, and is available at a low price. In recent years, it has been widely used as a wall material, and its surface has been coated with vinyl cloth, etc. Indoor walls are formed by pasting wallpaper.

However, although this gypsum board has the above-mentioned advantages, it is brittle and easily damaged by impact, so if the wall surface of the room is made of gypsum board, the projecting corners of the wall should not be used for storing utensils, etc. Easily damaged by contact.

Therefore, while it is often done to repair the damaged parts of the protruding corners with wallpaper of the same quality,
It is known to decorate and protect the projecting corner by pasting a corner tape as shown in Japanese Patent Publication No. 56-27667 to the projecting corner.

[Problem that the invention attempts to solve]

When damage occurs at the protruding corners of a wall made of gypsum board, repairing it using wallpaper of the same quality as the wallpaper pasted on the wall is easy if the area of the damaged area is relatively small, but it is difficult to repair. Differences in color, etc., tend to occur between the wallpaper used for this purpose and the wallpaper that has already been used, and the repaired areas become more noticeable, which is unfavorable in terms of appearance.

In addition, the corner tape provided at the corner disclosed in the above publication has an arcuate upper surface and an open space on the lower surface.
It has a flexible main body with substantially flat fastening pieces connected horizontally to the lower ends of both ends of the curved surface, and as can be easily understood from the installation state diagram shown in Fig. 2. If it is installed at a protruding corner, the curved surface will protrude, so it is not necessarily beautiful in appearance, and its structure is not simple, such as using a thin metal plate.There are many problems that need to be solved in practical terms. I have issues.

In view of the current situation, this idea was developed to protect the protruding corners of indoor walls by reinforcing them in advance, as well as to provide an inexpensive reinforcing material that can be repaired with a beautiful appearance even after damage has occurred. It is intended to provide.

[Means for solving problems]

In order to achieve the above object, the reinforcing material for the indoor protruding corner portion of this invention includes a thin part along the longitudinal direction in the center of a rectangular plate-like base having a predetermined width and made of a soft or semi-hard material. A pair of left and right plate-shaped bodies connected via the hinge are configured to be bendable to one side, and each of the left and right plate members on the side where the thin wall portion is provided has a peripheral edge portion removed. A concave portion is formed by forming a concave portion, an adhesive is provided on the entire surface of the concave portion, and a concave portion is provided on the plate member on the side where the thin portion is not formed except for the peripheral edge of the plate-like substrate, and a concave portion is provided on the entire surface of the concave portion. The invention is characterized by providing a flexible sheet material having a uniform thickness.

In this invention, the soft or semi-hard material constituting the reinforcing material is a thermoplastic synthetic resin such as polyvinyl chloride, polyethylene, or polypropylene, or synthetic rubber. A thin part is formed along the longitudinal direction in the center of the plate-shaped base to serve as a hinge,
It is constructed so that the plate-like bodies connected to the left and right with this hinge as a boundary can be bent to one side, but considering the ease of manufacturing and handling,
It is preferable that the width of the left and right plate-like bodies which are arranged consecutively with the hinge formed at the center of the plate-like base body as a border is about 30 to 50 mm, and the length is about 600 to 1500 mm.

An adhesive is provided on one side of such a reinforcing material, that is, on the side of the plate-like body on which the hinge is formed in the center, but this adhesive may be a semi-solid adhesive. Alternatively, it may be a double-sided adhesive tape or the like.

On the other hand, a flexible sheet material is provided on the other side, but the material used is felt, cloth,
Colored or uncolored sheet materials such as soft synthetic resin or soft rubber are used in appropriate colors and patterns to match the colors and patterns of the walls and pillars to be reinforced.

[Effect]

In the reinforcing material 1 of this invention, a hinge 3 is formed by providing a thin wall part in the center of a rectangular plate-like base having a predetermined width made of synthetic resin or synthetic rubber. a pair of plate-like bodies 2,
2 are integrally connected and can be bent almost at right angles to the hinge 3 side, so that it can easily come into contact with the corner part 7 of the wall 6 on which indoor wallpaper has already been pasted.

Therefore, an adhesive 4 for adhering the reinforcing material 1 to a wall surface or the like is placed in the recess 2a formed on the back side of the plate-like bodies 2, 2, with its top surface protruding from the recess 2a. Since the adhesive material 4 is provided, it can be easily and reliably attached to a wall surface, etc., and it is also possible to prevent a gap from being created between the peripheral edge of the concave portion 2a and the wall surface by adhesion. The reinforcing material 1 is kept in a good contact state so that the reinforcing material 1 does not come up, and the adhesive material 4 can be attached in a good manner without protruding from the peripheral edge.

Further, since the flexible sheet material 5 is provided in the concave portion 2b on the front side so that its top is flush with the peripheral edge, the sheet material 5 is reliably held within the concave portion 2b and peeled off. By keeping the reinforcing material flush with the peripheral edge and matching the material and color of the sheet material 5 with the interior, it is possible to create a reinforcing material with a good appearance.

〔Example〕

Hereinafter, one embodiment of the reinforcing material for the interior protruding corner portion of this invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a rear perspective view of the reinforcing material of the indoor projecting corner of this invention, Fig. 2 is a front perspective view of the same, Fig. 3 is a sectional view taken along the line A-A in Fig. 1, and Fig. 4 is a It is a perspective view showing a state of use.

In the drawings, 1 indicates a reinforcing material, and this reinforcing material 1 is made of, for example, polyvinyl chloride and has a thickness of 4 mm.
A hinge 3 is formed by thinning the central part of a vertically long plate-like base with a width of 60 mm and a length of 200 mm into an arc shape, and the plate-like bodies 2, 2 connected to the left and right through this hinge 3 are arranged at almost right angles to the hinge 3 side. It can be bent into
As is clear from FIGS. 1 and 3, the left and right plate-like surfaces on the side that can be bent by the hinge 3 have a recess 2a in the center, excluding the periphery.
An adhesive material 4 made of double-sided adhesive tape is provided in this recessed part 2a with the adhesive surface to the wall protruding from the recessed part 2a, and a plate-shaped adhesive material 4 is provided on the opposite surface as shown in FIG. A concave part 2b is formed in the center of the base except for the peripheral edge, and a sheet material 5 made of felt is provided in this concave part 2b so that its top surface is flush with the concave part 2b.

The adhesive material 4 is made of a material that can be adhered to the plate-shaped body 2 and the parts to be reinforced such as indoor walls, and is not a normal semi-solid pressure-sensitive adhesive. It is preferable to apply a coating or use a double-sided adhesive tape or the like, and to apply a release paper (not shown) to the surface and peel off the release paper as necessary.

As shown in FIG. 4, such a reinforcing material 1 is made by bending a plate-shaped body 2 at a substantially right angle in the longitudinal direction from a hinge 3, and attaching it to a protruding corner part 7 of an indoor wall 6 with the adhesive 4 side inward. If they make contact, the applied adhesive 4
is securely adhered to both sides of the wall 6 along the protruding corner 7 to cover the corner 7, thus protecting the corner 7 from damage due to impact or contact, and also covering up any corner damage that has already occurred. You can make it look better by doing so.

[Effect of idea]

The reinforcing material of this invention is made of a relatively fragile material such as gypsum board with an extremely simple structure, and is used to protect protruding corners of walls and pillars in rooms finished with wallpaper, etc., and to protect objects. In addition, it is possible to prevent damage that would otherwise occur, to cover up the damaged part that has already occurred, and to decorate the interior according to the interior decoration with the flexible sheet on the surface, thereby improving the appearance.

In addition, since the main part of this reinforcing material is made of materials such as synthetic resin without using metal materials, it is extremely lightweight and can be easily adapted to the part to be reinforced with adhesive, making it easy to carry around its own weight. There is no possibility of the product peeling off or falling off, and it can be installed reliably.

The main parts of this reinforcement material, the pair of plate-shaped bodies and the hinge part, are made of soft or semi-hard materials, so in addition to reinforcing and covering the corner parts, these materials can also be used to cushion the impact. This makes it possible to prevent injuries that often occur at protruding corners.

Furthermore, the pair of plate-like bodies and the thin hinge connecting them can be integrally obtained by molding the same synthetic resin or synthetic rubber, and the thin hinge is formed on one side of the plate-like body. By providing an adhesive in one recess and a sheet material in the other recess, the adhesive will not protrude from the recess when attaching the reinforcing material to a wall surface, etc.
In addition, the peripheral edge of the concave portion is securely in contact with the wall surface, and the reinforcing material can be securely fixed without coming up from the wall surface, and since the sheet material is securely held within the concave portion, it will not peel off during use. It has many practical advantages, such as no bending or rolling up, and the adhesive and sheet material only need to be attached to the recesses formed in the plate, making it extremely easy to manufacture and mass-produced. have
