Abstract

Gliding means are attached to a side frame of the car sling, said gliding means comprising a gliding part supported through elasticity means on a frame part. The side frame is positioned on a guide rail in an elevator shaft so that the gliding part of the gliding means sets on the guide rail. The gliding means is provided with an installation jig comprising a first branch positioned between the gliding part and the guide rail, and a second branch positioned in an open space between the frame part and the gliding part for bypassing the elasticity means. The installation jig is removed when the installation of the car sling and the car has been completed.

First claim

The invention claimed is:

1. A method for installing an elevator car sling associated with an elevator car, the method comprising:
inserting an installation jig in a gliding device, the gliding device including at least a frame, a gliding part, and an elasticity device, the elasticity device configured to support the gliding part on the frame, the installation jig including a first branch and at least one second branch, the first branch being positioned against an inner gliding surface of the gliding part to form a temporary gliding surface to glide on a guide rail, the at least one second branch being positioned in an open space between the frame and the gliding part to rigidly fix the gliding part to the frame such that the installation jig temporary bypasses the elasticity device;
attaching the gliding device to a side frame of the elevator car sling;
positioning the side frame having the gliding device attached thereto on the guide rail in an elevator shaft so that the gliding part of the gliding device is connected to the guide rail to install the elevator car sling; and
removing the installation jig after the elevator car is installed in the elevator car sling to install the elevator car sling.

2. The method according to claim 1 , wherein a horizontal cross section of the guide rail is T-shaped such that a vertical branch of the T-shaped guide rail forms a gliding surface for the gliding device.

3. The method according to claim 2 , wherein a horizontal cross section of the gliding part of the gliding device is U-shaped such that an inner surface of the U-shaped gliding device is connected to the gliding surface of the guide rail.

4. The method according to claim 3 , wherein a horizontal cross section of the frame of the gliding device is U-shaped such that the gliding part is inside the frame so that the frame and the gliding part open in a same direction.

5. The method according to claim 4 , wherein the elasticity device is on an outer surface of the gliding part such that elasticity device forms a U-shaped loop, the U-shaped loop having ends that are attached to outer end portions of two branches of the U-shaped frame such that the gliding part is attached to the frame only through the elasticity device.

6. The method according to claim 5 , wherein the installation jig includes the first branch and two second branches, the first branch being configured to fit into a bottom portion of the gliding part and the two second branches being configured to fit into a respective open space between a bottom portion of the frame and a bottom portion of the gliding part of the gliding device.

7. The method of claim 1 , further comprising:
fastening a lower transom associated with the elevator car sling to the side frame.

8. The method of claim 7 , further comprising:
installing the elevator car in the elevator car sling; and
fastening an upper transom associated with the elevator car sling to the side frame.

9. An elevator comprising:
a gliding device in a first position while installing an elevator car sling, the gliding device including at least a gliding part configured to glide on a guide rail, a frame and an elasticity device configured to apply an elastic force against a side frame of the elevator car sling when the gliding device is compressed towards a second position; and
an installation jig configured to,
hold the gliding device in the first position while installing the elevator car sling, the installation jig including a first branch and at least one second branch, the first branch being positioned against an inner gliding surface of the gliding part to form a temporary gliding surface to glide on the glide rail, the at least one second branch being positioned in an open space between the frame and the gliding part to hold the gliding device in the first position such that the installation jig temporary bypasses the elasticity device, and
detach from the gliding device after the elevator car is installed in the elevator car sling to allow the gliding device to compress toward the second position.
