In an insulating glass pane comprising two spaced glass panels which are sealingly joined at their circumference to form a sealed space in which a roller blind device is enclosed, the roller blind device includes a windup drum with a blind wound thereon and having a free end connected to a pull rod, and pull members are arranged at opposite ends of the drum and the pull rod is connected to the pull members. The pull members are operatively connected to a shaft on which the windup drum is rotatably supported for synchronous movement of the pull members and an electric is motor is provided for rotating the shaft and the pull members, the windup drum being rotationally connected to the shaft by way of a rotational torsion spring structure.
An insulating glass pane with an integrated roller blind device comprising two spaced glass panels hermetically sealed around the circumference thereof to provide a sealed space therebetween, in which said roller blind device is enclosed, said roller blind device comprising, within said sealed space, a wind-up drum supported on a rotatable shaft supported at one end of said sealed space, a blind connected with one end to, and being wound onto, said drum, the other, free, end of said blind being connected to a pull rod, a pull member arranged along each side of said sealed space at opposite ends of said drum and being operatively connected to said rotatable shaft for synchronous movement, said pull rod being connected at its opposite ends to said pull members, and an electric motor operatively connected to said pull members and said shaft for rotating said shaft and, at the same time, moving said pull rod for unwinding said blind from, or winding it onto, said drum.
A roller blind device for installation into a space formed between two spaced glass panels of an insulating glass pane, said roller blind device comprising a wind-up drum supported on a rotatable shaft, a blind connected with one end to, and being wound onto, said drum, the other, free, end of said blind being connected to a pull rod, pull members arranged at opposite axial ends of said drum and extending therefrom rectangularly and in parallel spaced relationship, said pull members being operatively connected to said rotatable shaft for synchronous movement, said pull rod being connected at its opposite end to said pull members, and an electric motor oepratively connected to said pull members and said shaft for rotating said shaft and, at the same time, moving said pull rod for unwinding said blind from or winding it onto, said drum
