[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wooden bracket and a wooden file, and more particularly to a safe metal fitting for attaching a wooden bracket and a highly safe wooden file.

[0002]

[Prior art]

 As is well known, brackets are attached to stairs in houses, corridors, entrances to entrances, staircases, or walls of tiles, and the brackets support the safety file. Focusing on the above bracket, it consists of a part that receives the file and a part that attaches to the wall surface.In the past, the bracket body as the part that receives the file and the bracket body itself Mounting brackets, which are the part that performs the mounting function, are integrally configured, and multiple brackets are passed through the mounting brackets to mount this bracket to the wall surface.

Further, focusing on the material of the bracket, it is often found that the whole body as a whole is mainly made of metal. In this way, since the bracket is made of metal, it feels cold to the touch, is not suitable for use in winter, and is not suitable for use in cold regions. There was a tendency to impair the feeling, and the decorativeness was poor. Further, it is possible to mount the bracket on the wall surface by passing a screw through a mounting bracket integrally formed with the metal bracket body, but the wall surface is made of wood or resin in some cases. Since only the metal surface of the metal fitting comes into contact with the wall surface, there is a possibility that the metal surface of the mounting metal fitting and the wall material may not be compatible with each other.

Therefore, there is also one in which the entire bracket is made of wood. According to this, the touch and hand impression are improved. In other words, it feels warm to the touch, is suitable for use in winter and in cold regions, gives a warm impression to the appearance, and can be used for various interior decoration effects. There are advantages such as ease of use. However, if the entire bracket is made of wood, it has the drawback of insufficient attachment strength, which could cause the bracket to drop in attachment strength and cause the file to fall off due to breakage. Further, since the conventional bracket is configured as a single body in which the bracket main body and the mounting bracket are integrated, if they are fixed to the wall surface with a plurality of screws, they can be easily attached to and detached from the wall surface. There wasn't.

[0005]

It was difficult to meet.

[0006] Focusing on the above-mentioned file, a metal file is also used, but a wooden file is often used inside the house. Many of the above-mentioned test files have a circular cross section perpendicular to the axis, but the diameter of the cross section of the conventional test file is relatively large, so that people with weak grip strength, old people, infants, etc. can not hold it. There was a problem. Therefore, in order to solve this problem, it is conceivable to reduce the diameter of the cross section of the wooden file, but this method has the advantage that the purchasing cost of the file itself can be reduced, but the file is easily broken and it is safe. There was a problem that it deteriorated in appearance and became poor in appearance.

The present invention has been devised in view of the above points, and its purpose is to have a wood-based merit that is warm to the touch and warm to the eye, has decorative properties, and is easily adapted to the wall surface. The advantages of metal that enhance the mounting strength on the wall surface are exhibited in harmony, and the bracket can be easily attached to and detached from the wall surface and has excellent functionality, while it is strong and easy to grip and looks The purpose is to provide a file that is warm and has a decorative effect.
