Abstract

Guide rail support assemblies for elevator systems are provided. The guide rail support assemblies include a junction element comprising a backing plate, a first extension, and a second extension, the junction element defining a rail cavity, wherein the rail cavity is configured to receive two rail sections, wherein the junction element is configured to join a first rail section to a second rail section and a mounting element configured to attach to a wall of an elevator shaft, wherein the mounting element is connected to the junction element.

First claim

What is claimed is:

1. A guide rail support assembly for an elevator system comprising:
a junction element comprising a first backing plate, a second backing plate, a first extension, and a second extension, the junction element defining a rail cavity, wherein the rail cavity is configured to receive two rail sections, wherein the junction element is configured to join a first rail section to a second rail section;
a mounting element configured to attach to a wall of an elevator shaft, wherein the mounting element is connected to the junction element;
a connector connecting the junction element to the mounting element with a stop extending from the connector, wherein the first backing plate is arranged on a first side of the stop and the second backing plate is arranged on a second side of the stop opposite from the first backing plate, and
wherein the stop is configured to divide the rail cavity into a first rail cavity and a second rail cavity, wherein the stop, the first backing plate, the first extension, and the second extension define the first rail cavity, and the stop, the second backing plate, the first extension, and the second extension define the second rail cavity, wherein the first rail cavity and the second rail cavity are defined on opposite sides of the stop,
wherein:
the first extension and the second extension are each connected to the first and second backing plates by first fasteners,
the first backing plate and the second backing plate are connected to the connector by second fasteners, and
the first fasteners are configured to apply a clamping force to the first and second extensions to secure and force contact and support for the first rail section and the second rail section arranged within the first and second rail cavities, respectively.

2. The guide rail support assembly of claim 1 , wherein the connector is adjustable to adjust a separation distance between the junction element and the mounting element.

3. The guide rail support assembly of claim 1 , wherein the stop has a profile in a shape of a cross-section of a rail section.

4. The guide rail support assembly of claim 3 , wherein the stop is part of the mounting element.

5. The guide rail support assembly of claim 1 , wherein the stop is part of the mounting element.

6. The guide rail support assembly of claim 1 , wherein each of the first backing plate and the second backing plate are attached to the mounting element.

7. The guide rail support assembly of claim 6 , wherein the first extension is connected to the first backing plate and the second extension is connected to the second backing plate.

8. The guide rail support assembly of claim 7 , wherein each of the first and second backing plates are connected to the mounting element.

9. The guide rail support assembly of claim 6 , wherein each of the first and second backing plates are connected to the mounting element.

10. The guide rail support assembly of claim 1 , wherein the mounting element is connectable to a wall of an elevator shaft by at least one third fastener.

11. An elevator system comprising:
a guide rail support assembly comprising:
a junction element comprising a first backing plate, a second backing plate, a first extension, and a second extension, the junction element defining a rail cavity, wherein the rail cavity is configured to receive two rail sections, wherein the junction element is configured to join a first rail section to a second rail section;
a mounting element configured to attach to a wall of an elevator shaft, wherein the mounting element is connected to the junction element; and
a connector connecting the junction element to the mounting element with a stop extending from the connector, the stop dividing the rail cavity into a first rail cavity and a second rail cavity, wherein the stop, the first backing plate, the first extension, and the second extension define the first rail cavity, and the stop, the second backing plate, the first extension, and the second extension define the second rail cavity,
wherein:
the first extension and the second extension are each connected to the first and second backing plates by first fasteners,
the first backing plate and the second backing plate are connected to the connector by second fasteners, and
the first fasteners are configured to apply a clamping force to the first and second extensions to secure and force contact and support for the first rail section and the second rail section arranged within the first and second rail cavities, respectively.

12. The elevator system of claim 11 , further comprising a first rail section installed into the first rail cavity and a second rail section installed into the second rail cavity to form a portion of a guide rail.

13. The elevator system of claim 12 , wherein the guide rail is one of a guide rail for an elevator car and a guide rail for a counterweight.

14. The elevator system of claim 11 , wherein the mounting element is fixedly attached to a wall of an elevator shaft.

15. The elevator system of claim 11 , wherein the connector is adjustable to adjust a separation distance between the junction element and the mounting element.

16. The elevator system of claim 12 , wherein the stop has a profile in a shape of a cross-section of a rail section of the guide rail.

17. The elevator system of claim 11 , wherein each of the first backing plate and the second backing plate are attached to the mounting element.

18. The guide rail support assembly of claim 11 , wherein the mounting element is connectable to a wall of an elevator shaft by at least one third fastener.
