Description

The present invention relates to a hardware that can improve the weaknesses of conventional wooden leg mounting hardware such as a table and can be used for various purposes and can be easily attached and detached.

Conventionally, when a wooden leg is attached to a table or the like, it is common to perform a process of embedding a hardware in the wooden leg so that the hardware cannot be seen from the outside.

However, in this hardware, the fiber of the wood is crushed by an impact from the outside, and the joint surface needs to be wobbled, and it is necessary to perform technical processing, and there is a problem that it is difficult for ordinary people to install.

In order to solve the above problem, there is a square leg hardware that inserts and fixes a wooden leg into a square hardware. However, in this proposal, since it is limited to wooden round legs, it will be compared with Patent Document 1. In this case, connection from the bottom of the round leg to the top plate by a long bolt is described.

Japanese Patent Application No. 6-6846

However, in the case of this round leg hardware, the entire leg is tightened with a long bolt, which can prevent wobbling of the leg, but has the following problems.

First, it is effective in the case of a short leg such as a table, but in the case of a long leg such as a table, an advanced technique is required to penetrate the center of the round leg.

Secondly, there is a risk of loosening of the bolt due to impact.

In view of such a situation, the present invention makes it possible to firmly connect the legs by a technique such as connection between metals, and to solve the above-mentioned drawbacks.

In order to solve the above-mentioned problem, a cylindrical female screw fitting with a collar attached on a wooden plate surface and a male screw fitting attached to a round bar-shaped wooden portion are attached, and the male screw fitting has a metal tip. The problem is solved by fixing to the wooden part with a wooden screw at the hole in each metal part and attaching by screwing the male and female screw metal fittings.

In this way, when the top plate and the leg portion are screwed, assembly and disassembly during transportation and transportation can be easily performed.

In a preferred form of the present invention, it can be used in various fields such as desks, tables and shelves by changing the size of hardware.

In a preferred form of the present invention, the hardware itself can be made difficult to see by drilling the top plate portion.

In a preferred embodiment of the present invention, when used for a shelf or the like, the number of steps and the height of the shelf can be easily adjusted.

In a preferred form of the present invention, it is also characteristic that hardware can be shown in a design sense.

In a preferred form of the present invention, it can be used with versatile ideas other than the purpose of the table leg.

In a preferred form of the present invention, it can be removed and used many times.

The present invention does not require a technical digging process of the wood part, can be easily attached only with wood screws, and can be assembled and disassembled during movement and storage.

It is an external appearance perspective view which shows-shape of this invention. It is an external appearance perspective view which shows the attachment form of this invention. It is an external appearance perspective view which shows the attachment form of this invention.

Hereinafter, the present invention will be described in detail with respect to preferred mounting forms shown in the drawings.
The technical scope of the present invention is not limited to the embodiment shown in the accompanying drawings, and can be appropriately changed within the scope described in the claims of the utility model registration.

FIG. 1 shows a hardware single body shape of the present invention. The cylindrical female screw (1) with a collar attached to a wooden board is shown, (1) 'has the shape which changed the attachment direction. a, c, and f are parallel screws, and the direction of insertion can be selected. b has a screw hole in a brim-like portion fixed to a wooden board, and a and b are integrated by metal drawing. At part b, fix with a wooden board and wooden screws. (2) is a metal fitting that is inserted into a wooden round leg, and is a cap-shaped male screw hardware that is fixed with a wooden screw at the head portion d and the insertion portion e. (3) is a form in which (1)-(3) is inserted into the through hole in the case of a shelf board, and the position is determined and fixed at both end portions g.

FIG. 2 shows a case where the hardware of FIG. 1 is attached to the table (1) ′-(2) in the form of attachment with the cylindrical screw-in portions exposed at the four corners of the plate surface. In the figure, holes are drilled at the four corners of the plate surface, and the cylindrical screw-in portion is embedded and attached. (A) and (B) show details of fixing hardware to wood with wooden screws.

FIG. 3 shows that in case of shelf production, the top plate part is a method of attaching (1)-(2) shown in FIG. 2, and in the lower part, through holes are made at the four corners of the plate surface (1)-(3). (1)-(3) (c) shows the details of fixing the hardware to the wood with wooden screws, respectively.
