Abstract

PROBLEM TO BE SOLVED: To provide a mounting structure, in which a screw is difficult to be loosened. SOLUTION: In the mounting structure of a handle, a fixture 3 screwed to a mounting surface F is inserted into the leg pipe 2 of the handle H while through-holes 6 are formed to the peripheral wall of the leg pipe 2 and a tapped hole 7 to the outer circumference of the fixture 3 respectively, and the handle H is fixed onto the mounting surface F by screwing a screw 8 into the tapped hole 7 through the through-holes 6. A large diametral section 11 and a small diametral section 12 are formed to the outer circumference of the fixture 3 through a stepped section 10 at that time, and the tapped hole 7 is positioned to the small diametral section 12. The peripheral wall of the leg pipe 2 is pushed into the inside with the screwing of the screw 8, friction is generated between the head section of the screw 8 and the peripheral wall of the leg pipe 2 by the restoring force of the peripheral wall, and the looseness of the screw 8 is prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle mounting structure for mounting surfaces such as doors and wall surfaces.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
As a mounting structure for mounting to a mounting surface F such as a door or a wall surface, a cylindrical mounting tool 3 is fixed to the mounting surface F with a bolt 5 through a washer 4, and the mounting tool 3 is inserted into the leg tube 2 of the handle H. In addition, it is known that a through hole 6 is formed in the peripheral wall of the leg tube 2 and a screw hole 7 is formed in the outer periphery of the fixture 3, and a screw 8 is screwed into the screw hole 7 through the through hole 6.

[0003]

However, in the mounting structure as described above, the screw may be loosened and the handle may be loose.

Further, clothes or the like may be caught on the head of the protruding screw.

Therefore, an object of the present invention is to provide a handle mounting structure in which screws are not loose.

[0006]

In order to solve the above-mentioned problems, the present invention inserts a fitting screwed to a mounting surface into a leg pipe of a handle and forms a through hole in a peripheral wall of the leg pipe.
In a handle mounting structure in which a screw hole is formed on the outer periphery of the fixture, and a handle is fixed to the mounting surface by screwing a screw into the screw hole through the through hole, a large step is provided on the outer periphery of the fixture. The diameter portion and the small diameter portion are formed, and the screw hole is located in the small diameter portion.

According to this mounting structure, as the screw is screwed in, the peripheral wall of the leg pipe is pushed inward, and the restoring force causes friction between the head of the screw and the peripheral wall of the leg pipe to loosen the screw. Is prevented.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. It should be noted that members corresponding to the conventional mounting structure shown in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIGS. 1 and 2, the handle H is formed by connecting leg tubes 2 to both ends of a grip portion 1. Fixture 3
A large diameter portion 11 and a small diameter portion 12 are provided on the outer periphery of the
Are formed. The screw hole 7 is located in the small diameter portion 12.

According to the above-mentioned mounting structure, as the screw 8 is screwed in, the peripheral wall of the leg tube 2 is pushed inward as shown by the arrow, and the restoring force between it causes the space between the head of the screw 8 and the peripheral wall of the leg tube 2 to be pushed. Friction occurs on the screw 8 and prevents the screw 8 from loosening.

[0011]

As described above, according to the present invention, as the screw is screwed in, the peripheral wall of the leg tube is pushed inward, and the restoring force thereof causes friction between the head of the screw and the peripheral wall of the leg tube. Since the screws are prevented from loosening, the fixed state of the handle on the mounting surface can be maintained.

Further, the protrusion of the head of the screw from the peripheral wall of the leg tube is prevented, and the safety is improved.
