Abstract

This high speed door (1), for closing or opening an opening made in a wall, comprises a bearing structure (3, 4) to which are attached a flexible curtain (2) and a drive system (5) enabling the curtain (2) to be moved from a closed position into an open position in which the curtain (2) is concertina-folded into the top of the opening. According to the invention, the bearing structure (3, 4) comprises two U-shaped vertical uprights (3) comprising a web (9) and two flanges (10) between which the curtain (2) is folded, each upright (3) being formed of at least one one-piece section piece (6) incorporating at least one cavity (7) oriented in the longitudinal direction of the section piece (6).

First claim

The invention claimed is:

1. A high-speed door for closing or opening an opening formed in a wall, the door comprising:
a bearing structure to which is attached a flexible curtain and a drive system enabling the curtain to be moved from a closed position into an open position in which the curtain is concertina-folded into a top of the opening, wherein the bearing structure comprises two cross-sectional U-shaped vertical uprights each comprising a web and two flanges extending perpendicularly from opposite ends of the web between which the curtain is folded, each U-shaped vertical upright being formed of a plurality of one-piece upright section pieces, wherein at least one one-piece section piece incorporates at least one cavity oriented in a longitudinal direction of the section piece;
a lintel comprising a plurality of lintel section pieces each incorporating at least one cavity oriented longitudinally, said lintel enclosing a shaft used to operate the flexible curtain; and
an attachment arrangement disposed on at least one of the upright section pieces and configured for fastening a secondary piece thereto, the attachment arrangement comprising:
a respective male attachment portion disposed on each of the flanges on one side of the at least one upright section piece opposite from the web and extending perpendicularly relative to the web along a longitudinal axis of the flange; and
two female attachment portions, each disposed on the web at an opposite side of the at least one upright section piece and each arranged collinear with the longitudinal axis of the respective flange;
wherein the male attachment portions are configured to engage a corresponding female attachment portion of the secondary piece and wherein the female attachment portions are configured to engage a corresponding male attachment portion of the secondary piece, and wherein the secondary piece comprises at least one of a second one-piece upright section piece or a finishing section piece.

2. The high-speed door according to claim 1 , wherein the at least one upright section piece incorporates a grid of cavities distributed over an entire transverse section of the upright section piece.

3. The high-speed door according to claim 1 , wherein a reinforcing means is engaged in the at least one cavity.

4. The high-speed door according to claim 1 , wherein a thermal or an acoustic insulating means comprising a foam is engaged in the at least one cavity.

5. The high-speed door according to claim 1 , wherein at least one U-shaped vertical upright of the two U-shaped vertical uprights comprises at least two upright section pieces each having a honeycomb cross section and placed end to end, and connected to a junction platen provided with pins designed to be engaged in the at least one cavity of the at least one upright section piece.

6. The high-speed door according to claim 1 , wherein the lintel comprises at least two lintel section pieces connected by a junction element.

7. The high-speed door according to claim 6 , wherein at least one flange has a return at a free end turned toward an inside of the at least one upright section piece.

8. The high-speed door according to claim 7 , wherein at least one of the male attachment portions is configured to engage with a corresponding female attachment portion of an end section piece provided with a return.

9. The high-speed door according to claim 1 , wherein the door comprises two brackets, each bracket having a respective platen abutting the web of a respective upright section piece.

10. The high-speed door according to claim 1 , wherein at least one electric member is fixed on an upright whereof a connecting wire is engaged in the at least one cavity of the plurality of upright section pieces forming the U-shaped vertical upright.

11. The high-speed door according to claim 1 , wherein at least one of the elements of the group consisting of a transverse connecting bracket, a U-shaped vertical upright of the two U-shaped vertical uprights, a junction element of a crosspiece, and a junction platen of a U-shaped vertical upright of the two U-shaped vertical allows direct or indirect fastening to a structure of a building or the opening.
