Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a handrail on a wall surface.

[0002]

2. Description of the Related Art When attaching a handrail to the wall surface of an elevator cage, an attachment structure as shown in FIG. 8 is often adopted in consideration of aesthetics and the like. The handrail H has a configuration in which a leg tube 3 is connected to both ends of the grip portion 1 via bent portions 2, and an end plate 50 having a screw hole 51 is press-fitted into the leg tube 3. A pair of through holes 52 are formed in the cage wall W in accordance with the intervals of the screw holes 51.
The leg pipe 3 is pulled toward the wall W by screwing the bolt 53 into the screw hole 51 from the outside of the cage via the, and the end face of the leg pipe 3 is in close contact with the wall surface F.

The inner diameter of the through hole 52 is the bolt 53.
Since the diameter is larger than the outer diameter of the shaft portion of No. 3, even if the distance between the screw holes 51 and the distance between the through holes 52 do not match due to a dimensional error that occurs when the handrail H is manufactured or when the through holes 52 are formed, By moving the bolt 53 in the hole 52, the bolt 53 can be screwed into the screw hole 51.

[0004]

However, according to the above-mentioned mounting structure, the handrail H is held inside the cage, and the bolt 53 must be screwed in from the outside of the cage. Therefore, at least two workers are required. In addition to the above, a tool for tightening the bolt 53 must be inserted between the wall surface of the hoistway and the cage, which causes a problem of poor workability.

Therefore, it is a technical object of the present invention to provide a mounting structure which is excellent in aesthetics and can be easily mounted with a handrail irrespective of a dimensional error of each part.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a fixture 10 having a tapered surface 18 on the outer periphery is provided on a wall surface F in a direction in which the smaller diameter side of the tapered surface 18 is the wall surface F side. Fixed with the mounting screws 16 toward the leg pipe 3 of the handrail H
The screw 21 into the leg pipe 3, and the screw 21 is screwed into the leg pipe 3.
In the attachment structure of the handrail in which the leg pipe 3 is brought into close contact with the wall surface F by moving the leg pipe 3 toward the small diameter side, the attachment 1
A small-diameter hole 11 and a large-diameter hole 13 communicating with the small-diameter hole 11 via a step portion 12 are formed to make the inner diameter of the small-diameter hole 11 larger than the outer diameter of the shaft portion of the mounting screw 16. ,
The inner diameter of the large-diameter hole 13 is made larger than the outer diameter of the head of the mounting screw 16, the seat plate 15 having the long hole 14 is inserted into the large-diameter hole 13, and the mounting screw is inserted into the long-hole 14 and the small-diameter hole 11. The shaft portion 16 is inserted and the seat plate 15 is fastened by the step portion 12 and the head portion of the mounting screw 16.

Further, a fixture 30 having a threaded portion 31 formed on the outer periphery is fixed to the wall surface F with a mounting screw 16, and the screw portion 31 is rotatably provided on the leg pipe 3 of the handrail H. In the handrail mounting structure in which the ring 32 is screwed in and the leg pipe 3 is brought into close contact with the fixture 30, a small-diameter hole 11 is formed in the fixture 30.
And a large-diameter hole 13 communicating with the small-diameter hole 11 via a step portion 12, and the inner diameter of the small-diameter hole 11 is set by a mounting screw 16.
And the inner diameter of the large diameter hole 13 is made larger than the outer diameter of the head of the mounting screw 16, and the seat plate 15 having the long hole 14 is inserted into the large diameter hole 13. The shaft portion of the mounting screw 16 may be inserted into the long hole 14 and the small diameter hole 11, and the seat plate 15 may be tightened by the step portion 12 and the head of the mounting screw 16.

The position of the fixture 10 relative to the mounting screw 16 can be changed along the slot 14.

A sleeve 17 is press-fitted into the leg pipe 3 of the handrail H, and the sleeve 17 is fixed to the leg pipe 3 by brazing or the like. Inside the sleeve 17, the attachment 10
Is fitted. A taper surface 18 having a smaller diameter toward the wall surface F is formed on the outer periphery of the fitting 10, and the leg pipe 3
An insertion hole 19 and a screw hole 20 are formed in the sleeve 17 and the sleeve 17, respectively. The screw 21 is screwed into the screw hole 20 through the insertion hole 19, and the tip of the screw 21 moves toward the small diameter side on the tapered surface 18 with the screwing, so that the leg pipe 3 of the wall body W moves. The end surface of the leg tube 3 is in close contact with the wall surface F.

According to the mounting structure as described above, the screw hole 6
Even when the distance between and does not match the center-to-center distance of the leg tube 3, the fixture 10 can be fitted inside the sleeve 17 by moving the fixture 10 while being temporarily fixed to the wall surface F.

FIG. 5 and FIG. 7 show a second embodiment. It should be noted that members having the same functions as those of the members of the first embodiment described above are designated by the same reference numerals, and description thereof will be omitted.

As shown in the figure, the wall surface F has a threaded portion 3 on its outer periphery.
