Problems solved by technology

This is not an easy job in narrow dark gaps and can easily lead to misalignment, which itself can lead to downtime or even injury to trapped passengers when the elevator is in normal use
Difficult working positions may also pose a risk of injury to the technician
Furthermore, difficult conditions and inconvenient working positions make the reliable adjustment of the landing gate rollers very slow according to the solutions of the prior art

Embodiment Construction

[0024] The main focus of the invention is to make the adjustment of the landing rollers of an elevator easier and easier by replicating the mutual horizontal distance of the leading or counter surfaces of the door coupler blades to a position where the adjustment of the landing rollers is easier to perform for reliable. Unless mentioned otherwise, the mutual horizontal distance of the dual surfaces here means the distance of the dual surfaces when the elevator car is moving in normal travel. In order to replicate this distance, it is sufficient to replicate the horizontal position of the dual surface of at least one blade.

[0025] In the examples described below, the transverse direction is defined as the direction in which the elevator doors are moving when they are opening and closing, and the depth direction (ie the direction of the depth of the elevator car) is perpendicular to the transverse direction.

Abstract

The invention relates to a method and apparatus for adjusting landing door rollers (5) in an elevator comprising at least an elevator car (2) having at least a car door (6), a door operating assembly (7) and a landing door coupler (8) with its two vanes (12), and the elevator comprising an elevator shaft (1) equipped with a landing door (4) at each landing level (3). For adjusting the landing door rollers (5) the mutual horizontal distance of the vanes (12) of the landing door coupler (8) is copied mechanically into the location further up in the elevator car (2) than the location of the vanes (12).

Description

technical field [0001] The invention relates to a method as defined in the preamble of claim 1 and a device as defined in the preamble of claim 9 for adjusting landing rollers. Background technique [0002] In conventional elevators, the door couplers that open and lock the landing doors are typically located in the door operator assemblies of the elevator car doors. The coupling is located directly above the elevator car door and is generally only visible in the elevator shaft from above in a narrow gap between the elevator car and the front wall of the elevator shaft. In order to be able to verify that the landing rollers are correctly centered with respect to the coupling and that the clearance is sufficient, the mechanic on the roof of the elevator car must lean on the front edge of the car and try to see both the landing rollers and the coupling blades . This is not an easy job in narrow dark spaces and can easily lead to misalignment, which itself can lead to downtim...
