Blind integrated in double glazing

Abstract

The invention relates to a blind integrated in a double glazing, that comprises a series of slats (11, 12, 13,...) connected together by at least two pairs of flexible strings on which the slats (11,12, 13,...) are successively attached at regular intervals, the two strings of a same pair being attached on or in the vicinity of a same longitudinal edge of each of the slats different from that onwhich or in the vicinity of which the two strings of the other pair are attached, wherein one of the pairs of strings (O, f4) is directly connected to at least one carriage (C1) driven in translationin a non-reversible manner by the rotation of a first endless screw driven in turn in rotation by an electric motor, while the other pair of strings (f1, f2) is driven by at least another carriage (C2) driven in translation in a non-reversible manner by the rotation of an endless screw driven in turn in rotation by the electric motor via a delay unit (R) designed in such a manner that a change inthe driving direction results in a modification of the orientation of said slats (11, 12, 13,...).

Description

technical field [0001] [01] The invention relates to curtains integrated in double glazing. [0002] [02] More particularly, the object of the invention is a curtain mechanism housed inside the double glazing, driven by an electric motor and controlled from the outside of the double glazing. Background technique [0003] [03] At present, glass bodies of the so-called double-glazed type are being used more and more widely due to their high conductive thermal insulation and sound insulation properties. [0004] [04] These glass bodies, known as double-glazed types, consist of two generally parallel sheets of transparent glass separated by a dry air space or a neutral gas space. These so-called double-glazed glass bodies are generally surrounded by a frame so that the inner cavity thus formed is sealed. [0005] [05] These glass bodies of the double-glazed type, like other glass bodies of the single-glazed type, are not practically immune to the ingress of energy by electroma...

Problems solved by technology

[0012] [12] On the other hand, it is preferable to have only a single motor to carry out all the functions of the curtain body (raising, lowering and orientation of the slats), because motors are expensive and power hungry, and in particular should be powered separately - which would Increase the number of wires required

[0013] [13] The repositioning of existing curtain mechanism systems does not allow the design of a curtain that is completely contained within the double glazing and that provides the possibility to control the lifting of the curtain as required and the required inclination of the panels of the curtain remotely possibility of
