Movable pedals for doors

Abstract

The invention relates to a movable platform for a door of a vehicle, in particular a rail vehicle, comprising a platform (1) protruding beneath a panel rail (2) at least substantially transversely to the direction of travel. In order to minimize the level difference between the pedal and the tread rail, on the end region of the pedal (1) remote from the vehicle, on at least one longitudinal beam (17) of the pedal (1), an at least substantially An upper pivot axis (16) extending parallel to the direction of travel, about which at least two pivot beams (18, 20) are pivotably mounted, said pivot beams each supporting a transverse profile (8-12), said pivot Each of the beams is fixedly connected only to that one transverse profile (8-12) assigned to the swing beam, while the other transverse profiles rest freely on the swing beam and are fixedly provided with a lifting mechanism (21 , 22, 23), the lifting mechanism lifts that horizontal profile (8-12) directly in front of the pedal bar (2).

Description

technical field [0001] The invention relates to a movable step for the doors of vehicles, in particular railway cars. Background technique [0002] Railway carriages are understood in the description and claims to mean all rail passenger vehicles, whether they be trams, subway trains, high-speed railway trains, commuter trains or tourist trains. The invention contemplates this application in particular, but it can also be advantageously used in other vehicle doors. [0003] In vehicles of this type, there is often the problem that during a stop between the floor on the one hand (actually the so-called running board, which forms the door-side end region of the floor) and the platform on the other hand, There are gaps in the horizontal direction and, in many cases, height differences as well. Various proposals have been made to bridge this gap jointly with or independently of the opening of the door, but all these attempts still have different disadvantages: After the pedal ...

AI Technical Summary

Problems solved by technology

[0003] In vehicles of this type, there is often the problem that during a stop between the floor on the one hand (actually the so-called running board, which forms the door-side end region of the floor) and the platform on the other hand, There are gaps in the horizontal direction and in many cases also height differences

Various proposals have been made to bridge this gap jointly with or independently of the opening of the door, but all these attempts still have different disadvantages: After the pedal is extended, there must also be a gap between the edge of the floor of the carriage and the opening of the door. Keep the difference in height between the upper edges of adjacent treads

A major disadvantage is the danger that this occurs above the platform and in some cases also in the contact area with the step when moving out

[0005] It is also proposed that the running boards be lowered or swung down onto the protruding running boards, but here, due to the structural height of the running boards, no real leveling can take place, and to allow a general application or even to implement it, on the one hand it is stuck. danger and on the other hand the risk of interference due to pollution is too great
