Problems solved by technology

[0006] The safety devices known from EP 1 813 566 B1 or WO 2005 / 044709 A1 have the disadvantage that a large space requirement is required for the sliding mechanism, whereby the braking wedge is applied to the guide rail
In the case of solutions implemented according to EP0968954 or EP0883567, strong damage to the track occurs due to the conveyor rollers

Embodiment Construction

[0038] figure 1 Shown in a schematic partial view corresponding to an embodiment of the invention for an elevator installation 2 ( Figure 4 ) of the sliding locking device 1 and rail 3. The sliding locking device 1 is used here to lock the elevator car 4 ( Figure 4 ) brake during braking.

[0039] During braking, the slide lock 1 cooperates or cooperates with the head 6 of the rail 3 via the braking element 5 . The braking surface 7 or the braking lining 7 faces the side 8 of the head 6 of the rail 3 here.

[0040] Furthermore, the slide lock 1 has an abutment surface 9 which is formed on the abutment body 10 and faces the braking surface 7 of the braking element 5 .

[0041] During operation, the braking element 5 is adjusted in the pressing direction 11 in the direction of the abutment surface 9 . In this case, firstly the rail gaps 12 , 13 are provided by the spacing 12 between the braking surface 7 and the side 8 of the rail 3 and the spacing 13 between the abutment...

Abstract

The sliding locking device (1) for an elevator installation (2) has a movable braking element (5), which can be directed against the abutment surface (9) in the pressing direction (11) for the braking operation Adjustment. In the installed state, the rail (3) is arranged between the braking element (5) and the abutment surface (9). A guide structure ( 44 ) for the braking element ( 5 ) is provided here, said guide structure having a guide surface ( 45 ) and an individual guide roller unit ( 43 ). The guide roller unit (43) cooperates with the guide surface (45) so that the adjustment of the brake element (5) in the direction of braking action (22) also takes place simultaneously with the braking in the pressing direction (11). Adjustment of moving element (5). The pressing directions (11) are each perpendicular to the braking action direction (22). The guiding roller unit (43) rolls on the guiding surface (45) during braking, and the guiding surface (45) is configured such that the braking element (5) proceeding in the braking action direction (22) proceeds decrementally The transition from the adjustment of the brake element (5) to the adjustment of the brake element (5) in the pressing direction (11). An elevator installation (2) having such a sliding locking device (1) and a method for braking an elevator car (4) implementable with such a sliding locking device (1) are also provided.

Description

technical field [0001] The invention relates to a sliding locking device for an elevator installation, an elevator installation with a sliding locking device and a method for braking an elevator car, which method can be carried out with the sliding locking device. Background technique [0002] An elevator safety device is known from EP 1 813 566 B1 in which a linearly displaceable braking wedge is guided on an incline in order to bring it close to the top end of the guide rail for braking. The linear movement of the brake wedge is thus achieved by a sliding mechanism. [0003] A sliding lock with a linearly displaceable braking wedge is known from WO 2005 / 044709 A1. Electromechanical manipulation is realized here. [0004] Locking devices with conveyor rollers are known from EP0968954 or EP0883567. During operation of the locking device, the delivery rollers transport the corresponding locking wedge into the braking position by squeezing it between the rail and the housin...
