Abstract

The invention relates to a sealing device ( 11, 35, 41 ) for sealing a gap ( 32 ) between a lintel ( 30 ) and a roller shutter ( 10, 34, 40 ). The sealing device ( 11, 35, 41 ) has a sealing means ( 23 ) for arranging at the upper end of a top shutter element ( 24 ) of the roller shutter ( 10, 34, 40 ). For covering a gap ( 32 ) in a functional and/or cost-effective way between a lintel ( 30 ) and a roller shutter ( 10, 34, 40 ), preferably in case of a completely unrolled door blade ( 12 ), the sealing device ( 11, 35, 41 ) is characterized in that a swivel mechanism ( 25, 37, 43 ) is provided for swivelling the sealing means ( 23 ) from a sealing position into a winding position and from a winding position into a sealing position.

First claim

I claim:

1. A sealing device for sealing a gap between a lintel and a roller shutter, the sealing device comprising:
a sealing means at an upper end of a top shutter element of the roller shutter;
a swivel mechanism arranged to swivel the sealing means from a sealing position into a winding position and from the winding position into the sealing position, wherein the swivel mechanism comprises a first swivel element for swiveling the sealing means from the sealing position into the winding position; and
a swivel axis, wherein the first swivel element and the sealing means are positioned to rotate opposite one another with respect to the swivel axis;
wherein the first swivel element and the sealing means rotate about the swivel axis to swivel the sealing means from the sealing position to the winding position, such that the first swivel element is moved towards the top shutter element and the sealing means is moved away from the shutter element;
wherein the roller shutter comprises a coiling device and wherein the swivel mechanism comprises a further swivel element fixed to the coiling device to rotate the first swivel element and sealing means about the swivel axis into the winding position.

2. The sealing device according to claim 1 ,
wherein the swivel axis comprises a hinge having a flexible rubber profile connecting the sealing means with the upper end of the top shutter element.

3. The sealing device according to claim 1 ,
wherein the sealing means extends traverse to or perpendicular to a plane of the roller shutter when the roller shutter is in a closed position; and
wherein the sealing means comprises a flexible sealing profile, a flexible sealing lip or an at least partly flexible sealing flap having a tubular cross-section.

4. The sealing device according to claim 1 ,
wherein the first swivel element extends traverse to or perpendicular to a plane of the roller shutter when the roller shutter is in a closed position; and
wherein the first swivel element is a rigid arm, bar, or projection.

5. The sealing device according to claim 4 ,
wherein the first swivel element and the sealing means are arranged in the same plane; and
wherein the sealing means rotates about the swivel axis downward to swing into the sealing position and
wherein the first swivel element rotates about the swivel axis upward to swing the sealing means into the sealing position.

6. The sealing device according to claim 4 ,
wherein the coiling device comprises a spiral shaped portion for coiling the shutter elements and wherein the further swivel element
is fixed to the coiling device in an area of a smallest radius of the spiral shaped portion of the coiling device; and
wherein the first swivel element or the further swivel element comprises one or more of a low friction material, a wear-resistant material, and a plastic.

7. The sealing device according to claim 1 ,
wherein the sealing means and first swivel element have a center of gravity and wherein the center of gravity is located on the same side of the swivel axis as the sealing means for allowing the sealing means to rotate about the swivel axis from the winding position into the sealing position under the effect of gravity.

8. The sealing device according to claim 1 ,
wherein the swivel mechanism further comprises at least one actuating element connected with the sealing means or the first swivel element, wherein the actuating element applies a force to swivel the sealing means from the winding position into the sealing position;
wherein the actuating element comprises one or more of a spring, a flexible cable, a flexible rod, and a flexible cord.

9. The roller shutter according to claim 1 adapted for opening and closing a doorway, further comprising:
a door blade, the door blade comprising:
a plurality of rigid shutter elements which are hinged with each other, wherein the top shutter element comprises one of the rigid shutter elements, and wherein the rigid shutter elements are guided by side rails at opposed sides of the doorway.

10. The roller shutter according to claim 9 ,
wherein the door blade is configured to be in a completely unrolled position when the sealing means of the sealing device is in the sealing position; and
wherein the door blade is configured to be in an at least partly up rolled position when the sealing means of the sealing device is in the winding position.

11. The roller shutter according to claim 9 ,
wherein the sealing means and the first swivel element extend traverse to or perpendicular to a plane of the top shutter element when the door blade is in a closed position; and
wherein the sealing means and the first swivel element extend parallel to the plane of the top shutter element when the door blade is in an up rolled position.

12. The roller shutter according to claim 9 ,
wherein the sealing device is a retrofit kit; and
wherein one or more of the swivel mechanism, the first swivel element, a second swivel element, and an actuating element are arranged on a left hand side or right hand side of the roller shutter.

13. The roller shutter according to claim 9 ,
wherein the side rails each comprise a slit;
wherein end pieces of the shutter elements are arranged inside the slits of the side rails, the slits guiding the shutter elements for opening and closing the doorway; and
wherein the door blade further comprises a carrying strap connected with the end pieces and with a coiling device to roll up and roll down the shutter elements.

14. The roller shutter according to claim 9 , further comprising:
a coiling device comprising a plurality of spiral discs;
wherein at least one of the spiral discs is arranged proximate to each end of a rotatable shaft;
wherein each of the spiral discs is shaped for receiving respective end sections of the shutter elements rolled up on the coiling device; and
wherein the spiral discs are spaced apart along the shaft a distance for receiving the end sections.

15. The roller shutter according to claim 9 ,
wherein the shutter elements are formed as lamellae, slats or panels, wherein the shutter elements are connected with each other by flexible joints or a flexible carrying strap for rolling up and unrolling the door blade on and off a coiling device.

16. The roller shutter according to claim 9 ,
wherein the roller shutter is a high speed roller door, and
wherein the door blade is configured to be moved with a speed in the range of 0.5 m/s to 5 m/s.

17. The roller shutter according to claim 16 ,
wherein the door blade is configured to be moved with a speed in the range of 1 m/s to 3 m/s.

18. The roller shutter according to claim 15 ,
wherein the shutter elements comprise foamed lamellae.

19. The sealing device according to claim 2 ,
wherein the sealing means extends perpendicular to a plane of the roller shutter when the roller shutter is in a closed position; and
wherein the sealing means comprises a flexible sealing profile, a flexible sealing lip or an at least partly flexible sealing flap, having a tubular cross-section.

20. The sealing device according to claim 5 , wherein the further swivel element
is fixed to the coiling device in an area of a smallest radius of the coiling device; and
wherein the first swivel element or the further swivel element comprise one or more of a low friction material, a wear-resistant material, and a plastic.
