System for guiding a swinging-sliding panel in particular for a vehicle door
First Claim
1. A guidance system for a swinging-sliding door panel for a public transportation vehicle, said panel comprising a vertical portion having a top and a bottom and extending parallel to a vertical wall of a vehicle body work and a top portion extending parallel to a roof of said vehicle bodywork and projecting inwardly relative to said vehicle bodywork, said vehicle bodywork having a top and a bottom, said system comprising:
- a bottom rail running along said bottom of said bodywork, said bottom rail including two generally aligned portions placed one after the other, with each said portion having a convex running surface comprising a horizontal rectilinear part and an end part having a free end, said end part being directed downwardly and inwardly towards said vehicle bodywork;
two bottom grooved wheels pivoted about a pivot axis on said bottom of said panel, said two bottom grooved wheels running respectively on each of said portions of said bottom rail, said rectilinear parts having a profile corresponding substantially to the profile of the groove of said bottom groove wheels as well as the profile of said end part in a transverse plane section comprising said pivot axis of said wheels;
at least one top rail having an end and running along said roof, said top rail including a horizontal guide path on said roof having a width delimited by two vertical edges which are parallel to each other and to a horizontal projection of one of said portions of said bottom rail, said vertical edges being of a height which is not less than the vertical distance between said horizontal part of said bottom rail and said free end of said end part of said bottom rail.

Abstract
The invention relates to a wrap-over swinging-sliding door (2) which swings into a closure position at the end of its closure stroke. The door is guided relative to the vehicle bodywork by a bottom rail (4) which co-operates with wheels (3a) fixed to the panel and by at least one top rail (7a, 7b) which is situated at roof level and which co-operates with a horizontal wheel (6a, 6b) which is guided therein and which is capable of moving vertically when the bottom wheels engage a swing-imparting slope which lowers the door at the same time as it moves the door into the bodywork.
