Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail holding device for holding a guide rail erected in a hoistway of an elevator.

[0002]

2. Description of the Related Art FIG. 4 is a side view showing a conventional example of a guide rail holding device. The guide rail holding device shown in FIG. 4 is connected to a first bracket 4 fixed to a wall portion 2 of a hoistway 1 via anchor bolts 3, and to the first bracket 4 via bolts 5. Second bracket 6
And a bolt 8 for fastening the guide rail 7 to the second bracket 6. The second bracket 6 described above includes a convex curved portion 9 whose center projects toward the bottom surface 10 of the guide rail 7 and which abuts on the bottom surface 10. An elongated hole (not shown) is formed extending in the direction along which the bolt 8 is inserted.

In this conventional holding device, the first bracket 4 is fixed to the wall portion 2 of the hoistway 1 via the anchor bolt 3, and the curved portion 9 of the second bracket 6 is fixed to the guide rail 7.
By bringing the bolt 8 into contact with the bottom surface 10 and inserting the bolt 8 into the elongated hole of the curved portion 9 and tightening the bolt 8, the first bracket 4 and the second bracket 6 are connected via the bolt 5. The guide rail 7 is held. When the guide rail 7 is not held vertically because the surface of the wall portion 2 of the hoistway 1 is uneven, the bolt 8 is loosened to guide the guide rail 7 against the convex curved surface of the curved portion 9. The bottom surface 10 is slid to change the contact position between the curved portion 9 and the guide rail 7, and the bolt 8 is tightened while the guide rail 7 is vertical. Then, the guide rails 7 erected vertically in this way
A car or a counterweight (not shown) is adapted to run.

In the conventional holding device thus constructed, the bottom surface 10 of the guide rail 7 is slid on the curved portion 9 of the second bracket 6 to guide the guide rail 7.
Can be easily adjusted to a vertical state, so that the work of installing the guide rail 7 in the hoistway 1 can be easily performed.

Incidentally, in connection with this type of device,
For example, those described in Japanese Utility Model Publication No. 1-94369 can be mentioned.

[0006]

In the conventional guide rail holding device described above, the second bracket 6 is used.
Since the guide rail 7 is held in a state where the curved portion 9 and the bottom surface 10 of the guide rail 7 are in line contact with each other, there is a problem that it is difficult to firmly hold the guide rail 7. For this reason, there is a concern that the guide rail 7 is considerably swayed when an unillustrated car or the like moves up and down along the guide rail 7, and the traveling accuracy of the car or the like is deteriorated.

The present invention has been made in view of the actual situation in the prior art, and an object thereof is to easily arrange the guide rail in a vertical state and to firmly hold the guide rail. To provide a holding device.

[0008]

In order to achieve this object, the present invention is a first fixed to a wall of an elevator hoistway.
And a second bracket for holding a guide rail standing upright in the hoistway, a guide rail holding device, wherein one end side is the first bracket and the other end side is the second bracket. The second bracket includes: an intermediate bracket that is respectively fastened and has a curved portion; and a movement permitting unit that allows relative movement of the intermediate bracket with respect to at least one of the first bracket and the second bracket. A flat plate-shaped vertical plate portion that comes into contact with the bottom surface of the guide rail, and another curved portion that comes into contact with the curved portion is formed on at least one of the first bracket and the second bracket. The guide rail is held via the bracket, the intermediate bracket, and the second bracket.

[0009]

Since the present invention is configured as described above, the first bracket is fixed to the wall of the hoistway, and the guide rail is attached to the bottom surface of the guide rail with the vertical plate portion of the second bracket abutting. Gripped by the second bracket, the first
At least one of the bracket and the second bracket, for example, the curved portion of the intermediate bracket is brought into contact with the curved portion formed on the first bracket, and in this state, one end of the first bracket and the intermediate bracket, The other end of the intermediate bracket and the second bracket are fastened to each other, that is, the intermediate bracket is interposed between the first bracket and the second bracket, so that the first bracket, the intermediate bracket, and the second bracket are connected. The guide rails are held via the brackets. At this time, since the vertical plate portion of the second bracket is formed in a flat plate shape, the second bracket is in surface contact with the bottom surface of the guide rail, and thus the bottom surface of the guide rail is in line contact. The guide rail can be held more firmly than in the case of

When the guide rail is not held vertically because the surface of the wall of the hoistway is uneven, the curved portion of the intermediate bracket is slid relative to the curved portion of the first bracket. Rotate the intermediate bracket, second bracket and guide rail until the guide rail is vertical. At this time, the movement permitting means causes the first
The relative movement of the intermediate bracket with respect to the bracket is allowed. Then, the intermediate bracket is fixed to the first bracket. As a result, the guide rail can be easily arranged vertically.

Although the case where the curved portion is formed on the first bracket has been illustrated as described above, the case where the curved portion is formed on the second bracket, or both the first bracket and the second bracket are formed. The same applies to the case where other curved portions that contact the curved portions of the intermediate bracket are formed in the.
