Abstract

The lifting door has slatted armor for closing the door aperture, the armor having hinge straps including hinge members connected to one another by pins for articulation of the straps relative to one another. The hinge straps are supported in guide tracks at the sides of the door aperture. The adjoining slats attached to the hinge members are spaced from one another and sealing strips extending approximately the entire door width afford a seal between the opposed registering opposite edges of adjoining slats.

Claims

1. A lifting door for a door aperture having two guide tracks respectively arranged on opposite sides of the door aperture, comprising:

a slatted door for covering the door aperture in a closed position of the door and having hinge straps, said hinge straps comprising hinge members connected to one another by pins for articulation of said straps relative to one another, said hinge straps having lengths which correspond substantially to the height of the door aperture, said hinge straps being supportable and guidable in the guide tracks;

slats attached to said hinge members and lying adjacent to and spaced from one another, the distance between respective adjacent slats forming a space for receiving the hinge pins; and

sealing strips extending approximately the entire door width between the hinge straps and connecting mutually opposite sides of adjacent slats.

2. A lifting door according to claim 1 wherein said slats have guides and said sealing strips are guided in the slat guides with minimum lateral play in a direction perpendicular to the plane of the door.

3. A lifting door according to claim 1 wherein said sealing strips include thickened portions having supporting faces on mutually opposite sides thereof and engaged in generally correspondingly shaped recesses of the slats.

4. A lifting door according to claim 1 wherein said slats have guides and said sealing strips are guided in the slat guides with minimum lateral play in a direction perpendicular to the plane of the door, said sealing strips including thickened portions having supporting faces on mutually opposite sides thereof and engaged in generally correspondingly shaped recesses of the slats.

5. A lifting door according to claim 1 wherein said sealing strips are arranged such that a geometrical axis of the hinge pins lies passes through the sealing strips, respectively.

6. A lifting door according to claim 3 wherein mutually confronting supporting faces of the thickened portions of the sealing strips are arranged at a minimum distance from corresponding holding faces of said slats.

7. A lifting door according to claim 1 including rollers mounted coaxially relative to the hinge pins for rolling guidance in the guide tracks.

8. A lifting door according to claim 1 including a sealing nose along widthwise extending edges of the slats on the side of the slatted door opposite said hinge straps for reducing the distance between adjacent slats.

9. A lifting door according to claim 1 including sealing lips on two mutually opposite sides of the door aperture and which project laterally as far as the position of the sealing strips in the closed position of the door.
