Venetian- or pleated blinds, particularly for multiple pane insulating glass window

Abstract

Venetian blinds, pleated blinds or the like, suspended in a cord drive system mounted in a housing, adapted to be positioned between the glass panes in a double glass window, particularly an insulating glass unit. The cord drive system is connected with a laterally arranged, longitudinal support shaft (16), mounted in the housing, which support shaft (16) is arranged rotatable as well as laterally displaceable in axial direction in order to accomplish winding and dewinding of the cord drives (10,12;66,68;78,78') in one single layer along parts of the support shaft, in order to hoist or ower the blind, respectively. The support shaft (16) is provided with threads in engagement with a threaded member (24,28), which is not rotatably connected in said housing (2), effecting that said support shaft (16) by rotation synchonously is being moved in axial direction.

Claims

2. The blind in accordance with claim 1, wherein the end of said winding shaft extends laterally through said at least one of said corner spacer elements and is configured to be connected to driving means located on the outside of the window.

3. The blind in accordance with claim 1, wherein said winding shaft includes at least one electrical motor for rotational driving of the winding shaft in either direction, said at least one electrical motor being provided with wiring means extending outside the window and configured to be connected to an electrical power source located outside the window.

4. The blind in accordance with claim 1, wherein said corner spacer elements are telescopically connected to the respective outer ends of the first and second housing members.

5. The blind in accordance with claim 1, wherein at least the horizontally extending arm on each of said corner spacer elements is configured to be insertably connected into the adjacent opening defined by the sealingly connected first and second housing members, and is sealingly connected to said first and second housing members.

6. The blind as in claim 2 wherein said one corner spacer element includes means for sealing said extended winding shaft end.

7. The blind as in claim 1 wherein said winding shaft includes a built-in electric driving motor..Iadd.

8. A sealed insulating glass window with a blind installed between the glass panes of the window, the glass panes spaced apart with spacer elements positioned around the circumference of the window and including an upper transversely extending spacer element and spaced-apart side spacer elements, the blind comprising:

a winding shaft including, as a unit, supporting and drive means therefore;

at least two sets of blind-supporting and winding cords connected in laterally spaced relationship to said winding shaft;

a housing in which the winding shaft is mounted and confined, said housing comprising the upper transversely extending spacer element, said housing also including two corner spacer elements attached to opposite ends of said housing, each of said corner spacer elements being attached to a respective adjacent side spacer element on each side of the window, and wherein at least one of said corner spacer elements is provided with a supporting bearing for rotatably receiving one outer end of the winding shaft;

a winding shaft extension; and

wherein said at least one of said corner spacer elements comprises sealing means for receiving said winding shaft extension therethrough, said winding shaft extension being supported for rotation by said sealing means, one end of said winding shaft extension being operatively connected to said one outer end of the winding shaft and another end of said winding shaft extension extending laterally through said at least one of said corner spacer elements and being configured to be connected to driving means located on the outside of the window..Iaddend..Iadd.

9. A sealed insulating glass window in accordance with claim 8, wherein said housing includes a two-part assembly of a lower substantially plate-shaped member cooperating to support said winding shaft, said plate-shaped member having longitudinally extending engagement means on opposite sides thereof, and a substantially U-shaped upper cover member having means for mating engagement with said plate-shaped member engagement means, said plate-shaped member and U-shaped upper cover member cooperating to confine the winding shaft therebetween..Iaddend..Iadd.10. A sealed insulating glass window in accordance with claim 8, wherein each of said corner spacer elements is a right-angled, profiled element having two arms, one of said arms being horizontally extending for attachment to an end of said housing, another of said arms being vertically extending for attachment to a top of said respective adjacent side spacer element..Iaddend..Iadd.11. A sealed insulating glass window as claimed in claim 8, wherein said corner spacer elements are telescopically connected to respective outer ends of said housing..Iaddend..Iadd.12. A sealed insulating lass window as claimed in claim 10, wherein said corner spacer elements are telescopically connected to respective outer ends of said housing..Iaddend..Iadd.13. A sealed insulating glass window in accordance with claim 9, wherein each of said corner spacer elements is a right-angled, profiled element having two arms, one of said arms being horizontally extending for attachment to an end of said housing, another of said arms being vertically extending for attachment to a top of said respective adjacent side spacer element..Iaddend..Iadd.14. A sealed insulating glass window as claimed in claim 13, wherein at least said horizontally extending arm on each of said corner spacer elements is configured to be received into an adjacent opening defined by said plate-shaped member and said U-shaped upper cover member..Iaddend.
