Abstract

A chair for chairlifts includes a pivotal installation that can pivot into a closed position and an open position, a locking element of the installation, and a blocking element for the locking element. The blocking element is movable into a blocking position and into a releasing position. A control element allows the blocking element to be moved from the blocking position and the installation to be opened. A chairlift and a method for activating a pivotable installation are also provided.

First claim

The invention claimed is:

1. A chair for chairlifts, the chair comprising:
a pivotable installation being pivotable into a closed position and into an opened position, said installation having a locking element;
a blocking element for said locking element, said blocking element being movable into at least one locking position and one releasing position; and
a control element for moving said blocking element from said locking position into said releasing position, said control element being connected to said installation, said control element configured for moving said installation into said opened position.

2. The chair according to claim 1 , wherein said control element has a control curve, and said blocking element bears against said control curve.

3. The chair according to claim 1 , wherein said locking element has at least one depression or recess in which said blocking element engages in said locking position.

4. The chair according to claim 1 , wherein said control element is operatively connected to said installation in only one direction of movement.

5. The chair according to claim 1 , which further comprises a bolt connected to said installation, said control element having an opening in which said bolt engages.

6. The chair according to claim 5 , wherein:
said bolt has a diameter;
said control element has a direction of movement and a path for moving said blocking element from said locking position into said releasing position; and

said opening has a length in said direction of movement of said control element being at least as large as said path of said control element plus said diameter of said bolt.

7. The chair according to claim 5 , wherein:
said bolt has a diameter and a length of movement from said opened to said closed position of said installation;
said control element has a direction of movement and a path for moving said blocking element from said locking position into said releasing position; and
said opening has a length in said direction of movement of said control element being at least as large as said length of movement of said bolt plus said path of said control element plus said diameter of said bolt.

8. The chair according to claim 1 , which further comprises a transmission installation for said control element.

9. The chair according to claim 8 , wherein said transmission installation has a mechanical, pneumatic, hydraulic, or electrical drive.

10. The chair according to claim 9 , wherein said transmission installation has a Bowden control or a linkage.

11. The chair according to claim 9 , wherein said transmission installation has a tilting element displacing said control element.

12. The chair according to claim 1 , wherein said blocking element engages in said locking element by way of a rotary or linear movement.

13. The chair according to claim 1 , wherein said installation is a safety bracket, a weather protection hood, a seat part, or a back part.

14. A chairlift, comprising:
a chair according to claim 1 .

15. The chair according to claim 1 , wherein said control element is directly connected to said installation.

16. A method for activating a pivotable installation being pivotable between a closed position and an opened position, the method comprising the following steps:
providing the installation with a locking element;
providing a blocking element being movable from a locking position into a releasing position for releasing the locking element; and
using a control element to initially move the blocking element to the releasing position and using the control element to then pivot the installation from the closed position to the opened position.

17. The method according to claim 16 , which further comprises closing the installation by moving the control element back to a position in which the blocking element is movable into the locking position.

18. The method according to claim 17 , which further comprises carrying out a return movement of the control element to pivot the installation into the closed position.

19. The method according to claim 17 , wherein the control element carries out the return movement by way of an elongate slot and leaves the installation in the opened position, requiring the installation to be closed manually.

20. The method according to claim 16 , which further comprises directly connecting the control element to the installation.
