Door provided with a curtain which is raisable by winding and has an improved lateral tightness

Abstract

A door including two lateral posts each having a slideway bounded by two wings, a transverse element connecting upper ends of the lateral posts, a flexible curtain having lateral edges engaging in each of the slideways, and means for winding the curtain into a door-opening position, where each of the slideways is equipped with a sealing profile having a back wall and two lateral walls substantially forming a U-shape, each of the lateral walls bearing against the wing which is adjacent to it.

1 . A door comprising:
 two lateral posts each having a slideway bounded by two wings,   a transverse element connecting upper ends of the lateral posts,   a flexible curtain having lateral edges engaging in each of the slideways, and   means for winding the curtain into a door-opening position,   
       wherein each of the slideways is equipped with a sealing profile having a back wall and two lateral walls substantially forming a U-shape, each of the lateral walls bearing against the wing which is adjacent to it. 
     
     
         2 . The door as claimed in  claim 1 , wherein each of the lateral walls is provided with at least one lip which is able to come into contact with a lateral edge of the curtain. 
     
     
         3 . The door as claimed in  claim 1 , wherein each lateral wall of the sealing profile is dimensioned to bear against the wing of the slideway which is adjacent to it. 
     
     
         4 . The door as claimed in  claim 1 , wherein the curtain has a continuous lateral edge flattened by high-frequency welding. 
     
     
         5 . The door as claimed in  claim 2 , wherein each of the lateral walls and each lip are tapered at their ends. 
     
     
         6 . The door as claimed in  claim 1 , wherein in a region of the upper end of each post, a guide head has a U-shaped cross section comprising a back wall and two lateral walls, each lateral wall being provided with a guide rib, the guide head being positioned in a continuation of each sealing profile.
