Abstract:
An entrance door for a premises, said door having one of its faces (15) turned toward an inside of said premises, where temperature deviations are relatively small over time, and its other face (38) is turned toward an outside of said premises where temperature deviations are higher, said door being equipped with means (6) to guide it into motion relative to a wall frame (5) on which it is meant to be mounted, and with means (3) to close it on said wall frame (5), said door having panels (9 and 10) that are joined together in superposition, and in a zone of their faces that are facing each other (20 and 37a), said means (3 and 6) being mounted on one of said two panels (9) and having its external face (15) turned toward the inside of said premises, said panels (9 and 10) respectively comprising at the periphery of their faces (4b and 37a) facing each other, means (3 and 34) to enable a displacement of the edges (18) of the panel (10) having its external face (38) turned toward the outside of said premises, relative to said internal panel (9) and in a plane parallel to the plane of said internal panel (9), said means (33 and 34) to enable the displacement of the edges (18) of the external panel (10) being made of identical profiles in the shape of flaps facing each other, said flaps being distributed over the entire width and the entire length of said faces (14b and 37a) of said panels (9 and 10), said flaps (33, 34) being parallel to said faces (14b and 37a) that face each other and practically in contact with each other, each flap (34) of the external panel (10) being positioned to slide over a corresponding flap (33) of the internal panel (9) with the sliding in the direction of the length and the width of the door (1).
