Abstract

PROBLEM TO BE SOLVED: To surely fix a mounting object to a mounted object, by diagonally screwing a wood screw. SOLUTION: In a fixed structure, formed with a through hole 5 in a mounting object 10 to screw a wood screw 1 to a mounted object 11 through this through hole 5 so as to fix the mounting object 10 by pressing it to the mounted object 11 by a head part 6 of the wood screw 1, a taper 14 diametrically spread toward the mounted object 11 is formed in the through hole 5, the wood screw 1 is diagonally inserted along this taper 14. Since the wood screw 1 can be diagonally screwed in even without enlarging a diameter of the through hole 5, the head part 6 of the wood screw 1 is prevented from coming off from the through hole 5. When the through hole 5 is formed in a slot long in a direction tilting the wood screw 1, it can be large tilted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for fixing a handrail, a handle, or the like to a wall or the like with a wood screw.

[0002]

2. Description of the Related Art For example, as shown in FIG. 4, in order to attach a handrail 2 to a wall surface 3 using a wood screw 1, a through hole 5 is formed in a flange 4 of the handrail 2, and a wood screw is inserted through the through hole 5. 1
Is screwed into the wall 3, and the flange 4 is pressed against the wall 3 with the head 6 of the wood screw 1.

At this time, in order to securely fix the handrail 2 to the wall surface 3, the wood screw 1 may be turned obliquely and screwed into a structural material 8 such as a pillar via a wall board 7.

[0004]

As shown in FIG. 5, in order to attach the attachment 10 to the attachment 11 by screwing the wood screw 1 obliquely, the diameter of the through hole 5 must be increased.

However, when the diameter of the through hole 5 is increased, the head 6 of the wood screw 1 comes out of the through hole 5 and
0 may not be fixed. If the washer 12 is used as a countermeasure as shown in FIG. 6, the workability is deteriorated.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to make it possible to securely attach an object to an object by screwing a wood screw obliquely without using a washer.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention forms a through hole in an attachment, screws a wood screw into an attachment through the through hole, and attaches the attachment to the head of the wood screw. In the fixing structure that is pressed against the mounting object with
Forming a taper in the through-hole that expands in diameter toward the object to be mounted;
Wood screws were inserted obliquely along this taper.

In this fixing structure, the wood screw can be screwed obliquely without increasing the diameter of the through hole, so that the head of the wood screw does not fall out of the through hole without using a washer.

Further, when the through hole is a long hole extending in the direction in which the wood screw is inclined, the wood screw can be largely inclined.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. In these embodiments, the wood screw 1 is obliquely screwed into the attachment 11 through the through hole 5 formed in the attachment 10 so that the head 6 of the wood screw 1 presses the attachment 10 against the attachment 11. The attachment 10 is provided with a counterbore 13 for immersing the head 6 of the wood screw 1. In each embodiment, the through hole 5 is formed with a taper 14 whose diameter increases toward the mounted object 11, and the wood screw 1 is inclined along the taper 14.

In the fixing structure as described above, the wood screw 1 can be screwed obliquely without increasing the diameter of the through hole 5, so that the head 6 of the wood screw 1 can be pulled out of the through hole 5 without using a washer. There is no.

Here, the embodiment shown in FIG.
2 shows a case where the head 6 is a plate head, and the embodiment shown in FIG.
The case where the head 6 of the wood screw 1 is a round head is shown.

When the through hole 5 is long in the direction in which the wood screw 1 is tilted as in the embodiment shown in FIG. 3, the wood screw 1 can be largely tilted.

The counterbore 13 need not always be provided, and may be omitted. In the embodiment shown in FIG. 3, the shape of the counterbore 13 may be an oval corresponding to the through hole 5.

[0015]

As described above, in the fixing structure according to the present invention, the wood screw can be screwed into the object to be mounted obliquely without increasing the diameter of the through hole formed in the object. The attachment can be securely fixed to the attachment without using a washer.
