Problems solved by technology

This can disadvantageously result in injury to the service technician, that is, when his hand is caught at the shaft door while the elevator car continues to drive
[0006] On the other hand, checking for the lowest degree of engagement is very time-consuming when the service technician has to carry out part of the inspection from inside the elevator shaft and another part from the floor

Embodiment Construction

[0025] figure 1 An elevator door 1 with an elevator door lock 2 is shown. The elevator doors 1 (shaft doors or car doors) can be arranged in a not shown elevator installation. The elevator door 1 includes a door leaf 34 and a door surround 35 . The elevator door lock 2 comprises locking elements 6 , 8 as well as bridging contacts, not shown. The locking elements 6 , 8 are a support 8 and a latch 6 . The latch 6 is pivotable and can be arranged on the door leaf 34 or on the door skirt 35 . The support 8 is arranged on the door collar 35 and the latch 6 is arranged on the door leaf 34 , or vice versa. When the elevator door 2 is locked, the bolt 6 and the abutment 8 are in engagement with each other, thereby preventing the opening movement OB of the door leaf 34 .

[0026] Instead of an arrangement of the bolt 6 or the support 8 on the door collar 35 , in an embodiment not shown, the bolt 6 or the support 8 can be arranged on an additional door leaf, wherein the bolt of the...

Abstract

A device and a method for checking or adjusting a depth of engagement of a locked elevator door lock, wherein the door lock has a catch engaged with a stop, can be fixed to the catch and have a region for supporting the stop. Alternatively, the device can be fixed to the stop and have a region for supporting the catch. The device can be fixed to the catch or to the stop such that a defined depth of engagement is formed when the stop or the catch is resting on the device support region.

Description

technical field [0001] The invention relates to a device for checking or adjusting elevator door locks and a method for using such a device. Background technique [0002] Known elevator installations comprise an elevator shaft, an elevator car that can travel in the elevator shaft, and a plurality of shaft doors. Shaft doors separate the individual floors from the elevator shaft. To ensure the safety of those staying on the floors, each shaft door must be latched. Such a shaft door can be unlocked when the elevator car is at the level of the shaft door. According to statutory standard EN81-1, the latching of the shaft door must precede the immediate movement of the elevator car. The shaft doors are latched by means of elevator door locks with locking elements. Thus, the locking element must have a defined minimum depth of engagement before the elevator door lock is considered to be an effective latch. [0003] In addition to the locking element, the elevator door lock u...
