DETAILED DESCRIPTION OF THE INVENTION

[0075]

TABLE-US-00001 Item No Door leaf 10 Baffles 20 Baffle channels 21 Bottom baffle 22 Transverse bar 24 Intermediate baffles 30 Bottom face 32 Top face 34 Common cord channels 40 Cords 50 Flexible web 60 Biasing cassette 70 Cassette channel 72 Friction element 74 Bottom part 76 Top part 78 Biasing element 80 Drag leaf engagement means 82 Drag leaf 90 Gate 100

[0076] FIG. 1 illustrates a door leaf 10 in an insulating state (FIG. 1A) and in an open state (FIG. 1B).

[0077] The door leaf 10 comprises insulating baffles 20 such that the door leaf 10 becomes an insulating door leaf 10.

[0078] The baffles 20 comprise a bottom baffle 22 and five intermediate baffles 30I, . . . ,30V. There may be more or fewer intermediate baffles 30 depending on the needed height of the door leaf 10.

[0079] The skilled person would understand that baffles 20 is a genus for the species bottom baffle 22 and the intermediate baffle 30.

[0080] The baffles 20 comprise baffle channels 21 forming in this embodiment three common cord channels 40 (shown with dashed lines in FIG. 1B). The three common cord channels 40 extend from the bottom baffle 22 through the one or more intermediate baffles 30.

[0081] The door leaf 10 comprises three cords 50 extending from the bottom baffle 22 through the three common cord channels 40.

[0082] The skilled person would know that the invention is not limited to three cords or three common cord channels as it may depend on the size of the door leaf i.e. width, height and weight of the door leaf.

[0083] In this embodiment, each baffle 20 is a separate unit, which is only interconnected by the cords 70 to the other baffles 20, this is clearly shown in FIG. 1B.

[0084] Each of the baffles 20 are wrapped in a flexible web 60.

[0085] The intermediate baffles 30I, . . . , 30V comprise a bottom face 32 facing the bottom baffle 22 and an opposite top face 34. The bottom face 32 being concave and the top face 34 being convex.

[0086] The interaction between a concave bottom face and convex top face 34 ensures that the door leaf 10 becomes tightly closed.

[0087] The bottom baffle 20 comprises a concave bottom baffle top face facing a bottom face 34 of an intermediate baffle 30V such that the door leaf 10 becomes tightly closed.

[0088] The bottom baffle 20 comprises a bottom face, which is adapted to close with a floor at the gate, thus the bottom face of the bottom baffle 20 will in most cases be substantially flat.

[0089] The flexible web 60 does not conform to the bottom face 32, when the intermediate baffles 30 are apart, this can be seen in FIG. 1B, however it is clearly shown in FIG. 2A. The result is a better connection between the baffles 20, when the baffles 20 are forced together as the flexible web 60 will have a biasing force directed to the baffle 20 below.

[0090] The door leaf 10 further comprises a biasing cassette 70. The general purpose of the biasing cassette 70 is to provide slack between the bottom baffle 22 and the biasing cassette 70, thereby allowing the door leaf 10 to be moved along curved paths.

[0091] The intermediate baffles 30I, . . . ,30V extend between the bottom baffle 20 and the biasing cassette 70.

[0092] The biasing cassette 70 comprises one or more cassette channels 72 in continuation of the common cord channels 40. The cassette channels 72 are shown with a dashed line in FIG. 1B, wherein the cassette channels 72 and the common cord channels 40 are slightly off-set because the baffles 20 and the biasing cassette 70 are not forced together.

[0093] The biasing cassette 70 have three friction elements 74 for frictionally gripping the one or more cords 50, such that the entire door leaf 10 can be forced into an insulating state (FIG. 1A) by pulling the cords 50. The door leaf 10 can be changed to an open state by adding more cord between the biasing cassette 70 and the bottom baffle 22.

[0094] The biasing cassette 70 further comprises a bottom part 76, a top part 78 and one or more biasing elements 80 (not shown) extending between the bottom part 76 and the top part 76. The biasing element is adapted for forcing the top part and the bottom part 76, 78 away from each other.

[0095] This will allow the door leaf 10 to provide slack to the cords 40 when the door leaf 10 is rolled together, the amount of slack is determined by the distance between the bottom part 76 and the top part 76 as well as the biasing element 80, the skilled person would by experiment be able to choose a design giving the necessary slack.

[0096] In this embodiment, the bottom part 76 and the top part 78 have U-shaped cross-sections facing each other and one part 76,78 being slideable within the other part 78,76.
