DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a structure for attaching a handrail to a wall surface.

[0002]

2. Description of the Related Art In attaching a handrail to a wall surface of an elevator car, an attachment structure as shown in FIG. The handrail H has a configuration in which leg tubes 3 are connected to both ends of the grip portion 1 via the bent portions 2, and an end plate 50 having a screw hole 51 is press-fitted into the leg tubes 3. A pair of through-holes 52 are formed in the wall W of the cage at intervals of the screw holes 51.
By screwing a bolt 53 into the screw hole 51 from the outside of the cage via the through hole, the leg tube 3 is drawn in the direction of the wall W, and the end face of the leg tube 3 is in close contact with the wall surface F.

The inner diameter of the through hole 52 is equal to the bolt 53
Is larger than the outer diameter of the shaft portion of the handrail H. Therefore, even when the distance between the screw holes 51 and the distance between the through holes 52 do not coincide with each other due to a dimensional error that occurs when the handrail H is manufactured or when the through hole 52 is formed, the through hole is 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-described mounting structure, the bolt 53 must be screwed in from the outside of the cage while holding the handrail H inside the cage, so that at least two workers are required. In addition, a tool for tightening the bolt 53 must be inserted between the wall surface of the hoistway and the cage, and there is a problem that workability is poor.

Accordingly, it is a technical object of the present invention to provide a mounting structure which is excellent in aesthetic appearance and can easily be attached to a handrail irrespective of a dimensional error of each part.

[0006]

In order to solve the above-mentioned problems, the present invention relates to a method of mounting a fixture 10 having a tapered surface 18 on the outer surface of a wall F in a direction in which the smaller diameter side of the tapered surface 18 is closer to the wall F. And fix it with the mounting screw 16 and the leg tube 3 of the handrail H.
Is screwed onto the leg tube 3 and a screw 21 is screwed into the leg tube 3.
In the handrail mounting structure in which the leg tube 3 is brought into close contact with the wall surface F by moving the leg tube 3 to the small diameter side along the line 8, the mounting tool 1
0, a small-diameter hole 11 and a large-diameter hole 13 communicating with the small-diameter hole 11 through a step portion 12 are formed so that the inner diameter of the small-diameter hole 11 is 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, a seat plate 15 having a 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. Sixteen shafts were inserted, and the seat plate 15 was tightened by the step 12 and the head of the mounting screw 16.

A mounting member 30 having a thread portion 31 formed on the outer periphery is fixed to the wall surface F with a mounting screw 16, and a tightening is provided on the screw portion 31 so as to be rotatable on the leg tube 3 of the handrail H. In the handrail mounting structure in which the ring 32 is screwed in so that the leg tube 3 is in close contact with the mounting member 30, the mounting member 30 has a small-diameter hole 11.
And a large-diameter hole 13 communicating with the small-diameter hole 11 via a step portion 12.
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. Alternatively, the shaft 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 12 and the head of the mounting screw 16.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the same members as those of the conventional mounting structure shown in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted.

FIGS. 1 to 4 show a first embodiment. As shown, the fixture 10 is fixed to the wall F.
The attachment 10 has a small-diameter hole 11, and the small-diameter hole 11 has a step portion 1.
2 and a large-diameter hole 13 communicating with each other. A seat plate 15 having a long hole 14 is inserted into the large diameter hole 13.

On the other hand, an auxiliary plate 4 is attached to the outer surface of the wall W, and a through-hole 5 and a screw hole 6 are formed in the wall W and the auxiliary plate 4, respectively. A mounting screw 16 is screwed into the screw hole 6 via the long hole 14, the small diameter hole 11, and the through hole 5. A bolt with a hole is used as the mounting screw 16.
The head is tightened.

The inside diameter of the small diameter hole 11 is larger than the outside diameter of the shaft portion of the mounting screw 16, and the inside diameter of the large diameter hole 13 is
6 is larger than the outer diameter of the head,
In the state where 0 is temporarily fixed to the wall F, as shown in FIG.
The position of the mounting tool 10 with respect to the mounting screw 16 can be changed along the elongated hole 14.

A sleeve 17 is press-fitted into the leg tube 3 of the handrail H, and the sleeve 17 is fixed to the leg tube 3 by brazing or the like. Inside the sleeve 17, the fitting 10
Is fitted. A tapered surface 18 having a smaller diameter toward the wall surface F is formed on the outer periphery of the fixture 10, and the leg tube 3 is formed.
The sleeve 17 has an insertion hole 19 and a screw hole 20, respectively. A 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 is The end face of the leg tube 3 is in close contact with the wall surface F.

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

FIGS. 5 and 7 show a second embodiment. Members having the same functions as those of the members of the first embodiment are given the same reference numerals, and description thereof is omitted.

As shown in FIG.
The fixture 30 formed with 1 is fixed. On the other hand, a tightening ring 32 is rotatably provided at an end of the leg tube 3. The tightening ring 32 is screwed into the screw portion 31, and the leg tube 3 is drawn in the direction of the wall W. The end face of the leg tube 3 is in close contact with the fixture 30.

In the mounting structure according to the second embodiment,
When the distance between the screw holes 6 does not match the center-to-center distance of the leg tube 3, as shown in FIG. 7, when the fixture 30 is temporarily fixed to the wall surface F, the tightening ring 32 is attached to the screw portion 31. Can be screwed.

In each of the above embodiments, the example in which the handrail is attached to the wall surface of the elevator cage is shown. However, the attachment structure according to the present invention can also be used when attaching the handrail to the wall surface of a building. In this case, a wood screw may be used as the mounting screw.

The present invention can also be used when attaching a handle or a towel rail instead of a handrail.

[0019]

According to the mounting structure of the present invention, since the mounting screws and the seat plate are not exposed on the wall surface side, an excellent appearance can be obtained.

In addition, all the mounting operations can be performed on the wall surface side, and dimensional errors of each part can be absorbed by moving the mounting tool with respect to the wall surface, so that the handrail can be easily mounted. it can.
