Abstract

The present invention relates to a coupling gear device for entraining a shaft door by means of an elevator car door that can be actuated by a door drive for elevator devices, comprising entrainment means ( 110 ) provided on the side of the elevator car door and counter entrainment means ( 210 ) arranged on the side of the shaft door. The counter entrainment means can be acted on by the entrainment means ( 110 ) for entraining the shaft door, wherein the entrainment means ( 110 ) and/or the counter entrainment means ( 210 ) can be lowered at least partially in the elevator car door or the shaft door.

First claim

We claim:

1. A device for entraining a shaft door with a lift car door, wherein the lift car door is actuated by a door drive, the device comprising catch means ( 110 ) provided on a lift car door side and counter-catch means ( 210 ) which are provided on a shaft door and that can be acted on by the catch means ( 110 ) to entrain the shaft door, characterised in that the catch means ( 110 ) and/or the counter-catch means ( 210 ) can be at least partly submerged into the lift car door and the shaft door respectively;
characterised in that the catch means ( 110 ) are initially moved vertically and then parallel to threshold leading edges ( 150 , 160 ) of the lift car door and shaft door when they act on the counter-catch means ( 210 ).

2. The device according to claim 1 , characterised by a carriage ( 102 ) on the lift car side which is moved on a lift car door by a drive ( 101 ), the carriage ( 102 ) being configured with rollers ( 108 ) that move during displacement by a connecting link ( 109 a) of a guide unit ( 109 ), the catch means ( 110 ) being coupled with the guide unit such that a movement of the rollers ( 108 ) through the connecting link ( 109 a) results in an extending of the catch means ( 110 ) with respect to the lift car door.

3. The device according to claim 2 , characterised in that the drive is configured to be self-locking.

4. The device according to claim 2 , characterised in that the drive is configured to be programmable.

5. The device according to claim 2 , characterised in that the carriage ( 102 ) has a driver ( 10 ) that acts on a lever provided on the catch means ( 110 ), thereby causing the catch means ( 110 ) to spread apart.

6. The device according to claim 2 , characterised in that the drive provides a single-dimensional movement which is converted into a complex movement by mechanical means.

7. The device according to claim 1 , characterised in that the catch means ( 110 ) are configured to be extensible and can be at least partly submerged into the shaft door to act upon the counter-catch means ( 210 ).

8. The device according to claim 1 , characterised in that the catch means ( 110 ) are configured as expander skate angles.

9. The device according to claim 1 , characterised in that the counter-catch means ( 210 ) are configured as rollers provided on the shaft door.

10. A lift comprising a device for entraining a shaft door with a lift car door, wherein the lift car door is actuated by a door drive, the lift comprising: catch means ( 110 ) provided on a lift car door side and counter-catch means ( 210 ) which are provided on a shaft door and that can be acted on by the catch means ( 110 ) to entrain the shaft door, characterised in that the catch means ( 110 ) and/or the counter-catch means ( 210 ) can be at least partly submerged into the lift car door and the shaft door respectively; and
characterised in that the catch means ( 110 ) are initially moved vertically and then parallel to threshold leading edges ( 150 , 160 ) of the lift car door and shaft door when they act on the counter-catch means ( 210 ).

11. The device according to claim 2 , characterised in that the drive is configured to be non-self-locking.
