Description

TECHNICAL FIELD

[0001] The present invention relates to a door operator arrangement for opening and closing an opening.BACKGROUND

[0002] So called high speed doors are used for facilitating high speed opening, e.g. for vehicles or the like. In order to facilitate such high speed opening, flexible curtains are used. Such flexible curtains, however, do not have stability regarding deflection caused by wind load and thermal insulation is low. The sealing in side frames is difficult in combination with stiffening elements for wind load capability. In order to absorb higher wind loads, the door curtains are reinforced with aluminium profiles. The door curtains may further be insulated with foam to reduce the temperature passage.

[0003] EP1409830B1 discloses a pneumatic roller blind constructed from a pneumatic body, comprising a spacer material in which two material layers are connected by means of a number of spacer threads. The pneumatic body comprises two lateral closures and one of each of an upper and lower end closure, with a bar attached to the latter, the weight of which can draw the roller blind downwards. The whole pneumatic body is coated with a layer of flexible plastic and thus made airtight. The roller blind is provided with sheets on the outside thereof, which extend over the whole width thereof. When the roller blind, which can be fully wound on a tube around an axis, is fully unwound, said blind can be pressurised with air pressure, thus tensioning the distance threads and the lateral and end closures contact with the structural parts of a building which surround the roller blind.

[0004] There is however a need to provide a door operator arrangement which may provide high speed door movement, which facilitates efficiently reducing deflection due to wind load and which facilitates providing thermal insulation for exterior applications.OBJECTS OF THE INVENTION
