Description

  The present invention relates to a corner shelf for attaching to a wall corner portion, and a corner shelf support member for attaching the corner shelf to a wall surface mainly made of gypsum board.

A corner shelf with a corner plate having an inner angle of 90 degrees and a side plate connected to the periphery of the shelf plate is mounted in advance with a fixed-width plate-shaped mounting member on the wall surface using a screw. There have been proposed ones that have shelves attached (see Patent Documents 1 to 3), and those that have the side plates abutted against the wall surfaces and fixed to the wall surfaces using screws to attach the corner shelves to the wall corners. (See Patent Document 4 or Non-Patent Document 1).
A shelf composed of a shelf plate and a side plate that is attached to a flat portion rather than a corner portion of the wall surface has been proposed in which the rear surface of the side plate is in contact with the wall surface and the shelf is attached to the wall surface using screws (see Non-Patent Document 2). .
The shelves disclosed in Patent Documents 1 to 4 and Non-Patent Documents 1 and 2 are configured to attach the shelves to the wall surface with screws. Therefore, when the shelf is removed from the wall surface, a screw screw hole that is visible on the wall surface is opened. When moving out of a rental property, the lessee needs to recover. Because the aesthetics of the wall are damaged by the opening formed after extracting the screws stuck in the wall, the value of the rental property is inferior, and the new contract becomes disadvantageous, so the lessee will become the lessor when the tenant leaves You may be required to pay for the restoration.
By the way, in most cases, the interior angle of the corner portion of the wall surface is not 90 degrees, and is generally 90 ° ± 1 to 3 °. In addition, the wall surface is often not exactly vertical, and is often slightly inclined forward or backward by 1 to 5 degrees. When the shelf disclosed in Patent Literatures 1 to 4 and Non-Patent Literature 1 or 2 is fixed, the side plate and the wall surface that are suspended from the rear surface of the shelf plate and are attached to the wall surface of the shelf when the inner corner angle of the wall surface exceeds 90 ° If the inner corner of the wall is less than 90 °, pressure is applied between the side plates. If the shelf is made of synthetic resin, the shelf may be bent and damaged. Otherwise, there is a drawback that the mounting surface is inclined according to the inclination amount of the wall surface and cannot be kept horizontal.
Therefore, in order to solve the above-mentioned drawbacks, the present inventor has provided a hook-shaped shock absorbing portion at the connecting portion between the receiving member and the vertical member, and the vertical member is inclined inward or outward with the hook-shaped shock absorbing portion as a fulcrum. By making the back of the vertical member in close contact with the wall surface, a gap is formed between the receiving member and the wall surface, and a corner shelf in which the receiving member does not bend is created. Patent application as Japanese Patent Application No. 2017-183027 Did.
In the invention according to Japanese Patent Application No. 2017-183027, the vertical member is fixedly attached to the wall surface corner portion by directly driving the stapler needle from the front side of the vertical member in contact with the wall. A worker who attaches to the wall surface has a disadvantage that he has to perform a work of driving the stapler in a posture of looking into the bottom surface of the receiving member from below the corner shelf.
In order to eliminate this drawback, the present inventor is not a corner shelf alone, but a corner shelf in which a vertical member is provided with a locking groove perpendicular to a receiving member, and a flat belt-like body having a constant vertical width and a long horizontal width. A corner shelf support member provided with a locking piece perpendicular to the upper edge of the flat belt-like body, that is, a vertical locking piece protruding at an angle of 90 degrees with the front surface of the flat belt-like body and provided with a stapler needle driving portion. We focused on using these two items. First, the rear surface of the corner shelf support member is brought into contact with the wall surface, the stapler needle is driven into the stapler needle driving portion to attach the corner shelf support member to the wall surface, and then the locking piece is inserted into the locking groove of the vertical member. Thus, the corner shelf is attached to the wall corner portion with the corner shelf support member interposed. Although the present inventor has the advantages that the positioning operation and the like are simple and the corner shelf support member is not visually visible, when the downward pressing is applied to the front side end of the upper surface of the receiving member, the locking piece I noticed that there was a drawback that the corner side of the corner shelf was lifted upward, and the corner shelf dropped from the corner shelf support member. In other words, there is a problem that there is a limitation on the placement position and load of the object on the receiving member that the object cannot be placed near the front edge of the corner shelf.
Note that Patent Document 5 is not a document that discusses the inventive step of the present invention because the grooves are recessed in the horizontal direction. Since patent document 6 is a structure which inserts a pin in the vertical member which has a perforation, and attaches it to a wall surface, it does not become literature which discusses the inventive step of the present invention.
