Abstract

An elevator guide rail fixing clip has a u-shaped clip body configured to encompass a side edge of an elevator guide rail and a fastening element. The fastening element is fastened to the clip body and is configured to mount the clip body to a fixed structure of an elevator runway. The clip body includes a base wall, a side wall and a cover wall forming the three members of the u-shaped body. At least one of these walls has at least one projection protruding from the respective wall configured to contact the guide rail, which projection has a contact face for contact with the elevator guide rail. The fixing clip allows the fastening of a guiderail in a horizontal plane but with reduced friction against vertical sliding of the guide rail to compensate for building shrinkage.

First claim

The invention claimed is:

1. An elevator guide rail fixing system, comprising:
the elevator guide rail; and an elevator guide rail fixing clip, comprising:
a u-shaped clip body configured to encompass a side edge of the elevator guide rail; and
a fastening element including a bolt and a bolt head, the fastening element being fastened to the clip body and configured to mount the clip body to a fixed structure of an elevator runway,
wherein the clip body comprises a base wall, a cover wall, and a side wall connecting the base wall and the cover wall, the base wall, the side wall and the cover wall forming three members of the u-shaped body, and the fastening element is fastened to the base wall of the clip body, and
wherein the bolt head forms a projection protruding from the base wall and configured to contact the guide rail via a contact face being a tip of the bolt head.

2. The elevator guide rail fixing system according to claim 1 , wherein the contact face is a rounded element.

3. The elevator guide rail fixing system according to claim 1 , wherein the side wall is connected to the base wall at a first edge and the cover wall is fixed to the side wall at a second edge which is parallel to the first edge.

4. The elevator guide rail fixing system according to claim 3 , wherein a distance between the cover wall and the base wall on a side of a free edge, opposite to the second edge, of the cover wall is equal to or smaller than a distance between base wall and cover wall on a side of the second edge.

5. The elevator guide rail fixing clip according to claim 1 , wherein the side wall and the cover wall each further include a projection different from the projection formed by the bolt head.

6. The elevator guide rail fixing clip according to claim 5 , wherein the projection formed by the bolt head of the bolt is larger than the projections in the side wall and cover wall.

7. The elevator guide rail fixing system according to claim 1 , wherein the projection is a sphere segment.

8. The elevator guide rail fixing system according to claim 1 , wherein the u-shaped clip body is a one-piece part.

9. The elevator guide rail fixing system according to claim 8 , wherein the one piece part is a metal sheet with a thickness of 2 to 15 mm.

10. The elevator guide rail fixing system according to claim 8 , wherein the one piece part is a spring metal sheet.

11. An elevator, comprising:
at least one of the elevator guide rail fixing system according to claim 1 ,
wherein the elevator guide rail fixing clip of the at least one of the elevator guide rail fixing system is part of a guide fixing bracket located in an elevator runway.

12. The elevator according to claim 11 , wherein each guide fixing bracket has two guide rail fixing system mounted to a horizontally extending bracket member of the guide fixing bracket opposite to each other.

13. A method for mounting an elevator guide rail, said method comprising the steps of:
providing two of the elevator guide rail fixing clips of the elevator guide rail fixing system according to claim 1 ;
mounting the two fixing clips to opposite sides of the guide rail, respectively;
mounting the two fixing clips to a bracket member of a guide fixing bracket; and
mounting the bracket member to a fixed structure in the elevator runway.

14. The elevator guide rail fixing system according to claim 8 , wherein the one piece part is a metal sheet with a thickness of 3 to 10 mm.

15. The elevator guide rail fixing system according to claim 2 , wherein the side wall is connected to the base wall at a first edge and the cover wall is fixed to the side wall at a second edge which is parallel to the first edge.

16. The elevator guide rail fixing system according to claim 15 , wherein a distance between the cover wall and the base wall on a side of a free edge, opposite to the second edge, of the cover wall is equal to or smaller than a distance between base wall and cover wall on a side of the second edge.
