A flexible guide for a door includes straps that are mounted in pairs along either side of a doorway. As the door opens and closes, the straps guide the vertical movement of a door panel that travels within the channel. The straps are pulled in tension between upper and lower anchors to provide the straps with enough stiffness to effectively hold the door panel within the channel under normal operation. In some embodiments, springs are used to maintain the tension in the straps. The straps are also sufficiently pliable and resilient to allow an impact to dislodge the door panel out from within the channel without damage. The upper or lower anchor is moveable between a normally extended position and a yielded position to prevent an impact from breaking the anchor and may further be biased to the normal position.

L'invention concerne un guide flexible pour portes comportant des sangles mont~es par paires le long des deux cÙt~s de l'entr~e de porte. Les sangles de chaque paire sont g~n~ralement parall­les, se font face et sont espac~es les unes des autres afin de cr~er un espace ou un canal entre elles. Lorsque la porte s'ouvre et se ferme, les sangles guident le mouvement vertical d'un panneau de porte le long dudit canal. Pour conf~rer aux sangles une rigidit~ suffisante leur permettant de maintenir efficacement le panneau de porte dans ledit canal dans des conditions de fonctionnement normales, lesdites sangles sont tendues entre le dispositif de fixation sup~rieur et le dispositif de fixation inf~rieur. Dans certains modes de r~alisation, des ressorts permettent de maintenir la tension dans les sangles. Ces sangles sont ~galement suffisamment flexibles et ~lastiques pour qu'un impact puisse d~loger le panneau de porte hors dudit canal sans occasionner de dommages. Le dispositif de fixation sup~rieur et le dispositif de fixation inf~rieur peuvent basculer entre une position normalement d~ploy~e et une position d~form~e, ce qui permet d'~viter qu'un impact ne brise le dispositif de fixation. Par ailleurs, le dispositif de fixation sup~rieur et le dispositif de fixation inf~rieur peuvent Útre ramen~s ~ force en position normale.
