Definitions

  • the present invention relates to a device for controlling and actuating the stroke of light-blocking means in double-glazing units.
  • a double-glazing unit is usually constituted by a rectangular frame which supports at least two transparent or translucent panes which are mutually parallel and spaced so as to form a chamber which is isolated from the outside and inside which light-blocking means are accommodated.
  • Said blocking means are currently usually constituted by shutters or Venetian blinds or other equivalent devices which are moved in any manner from an extended light-blocking configuration to a gathered or rolled-up configuration which allows said light to pass freely, and viceversa, by means of actuator means.
  • the actuator means if they are of the automatic type, are usually constituted by motor means which are accommodated outside the double-glazing unit in suitable containment casings and move the light-blocking means by means of kinematic systems which are partially internal and partially external.
  • the encoder has the purpose of counting the turns made by the shaft for rolling up the gathering cables or the light-blocking means themselves, and the microprocessor has the purpose of comparing the data transmitted by the encoder with the data stored inside the microprocessor.
  • the microprocessor actuates the motor means.
  • the means for controlling and actuating the movement of the light-blocking means of the above described type burden, in terms of components, the overall structure of the double-glazing unit and constitute a significant cost.
  • fixed stroke limits are used which are located between two preset positions of a female thread coupled to a worm screw and are part of means for reducing the rotation rate of the motor.
  • the aim of the present invention is to provide a device for controlling and actuating the stroke of light-blocking means in double-glazing units, which solves the above-described drawbacks of conventional models, particularly by providing precise and safe movement of the light-blocking means without however entailing the provision of holes or openings on the panes that form the double-glazing unit for the passage of measurement signals.
  • an object of the present invention is to provide a device whose precision in moving and stopping light-blocking means in preset positions is combined with a reduced number of components, consequently improving production and assembly costs.
  • Another object of the present invention is to provide a device which is particularly reliable and can be applied to various kinds of light-blocking means.
  • Another object of the present invention is to provide a device which can be integrated in a double-glazing unit without altering its aesthetic and styling levels.
  • Another object of the present invention is to provide a device which can be manufactured at low cost with conventional equipment.
  • a device for controlling and actuating light-blocking means in double-glazing units of the type constituted by a rectangular frame which supports at least two transparent or translucent panes which are mutually parallel and spaced so as to form a chamber which is isolated from the outside and inside which light-blocking means are accommodated and moved, by actuator means, from an extended configuration for blocking the light to a gathered or rolled-up configuration which allows light to pass freely, and viceversa
  • said device being characterized in that it comprises at least one permanent magnet which is associated with said light-blocking means and at least one sensor which is energized by said at least one magnet and is fixed to said frame in order to signal that said light-blocking means have passed and/or have reached their position.
  • a double-glazing unit to which a device according to the present invention described in detail hereinafter is applied, is generally designated by the reference numeral 10.
  • the double-glazing unit 10 is of the type constituted by a rectangular frame 11 which supports, in this case, two transparent panes 12 which are mutually parallel and spaced so as to form a chamber 13 isolated from the outside and inside which light-blocking means are accommodated; in this case, the light-blocking means are constituted by a device known as "Venetian blind” and generally designated by the reference numeral 14.
  • the Venetian blind 14 in particular, is constituted by a plurality of laminar elements which lie longitudinally and have a slightly curved cross-section; those elements are arranged substantially parallel to each other and are connected, at their end, by a cord 15 which is moved as described hereinafter so as to gather them in a pack or spread them out in a configuration which is adapted to block the light.
  • an element 16 which has the same extension as the laminar elements and which, by means of its weight, guides the arrangement of the Venetian blind 14 during transitions from the gathered condition to the extended configuration and viceversa.
  • the movement of the Venetian blind 14 occurs by connecting the cord 15 to a shaft 17 by means of pulleys, not shown; the shaft is in turn connected to external motor means 18 contained in a casing 19 which hides them from sight from outside.
  • a device for controlling and actuating the stroke of the light-blocking means is associated with the double-glazing unit 10 which comprises a permanent magnet 20, which is fixed to the element 16, and two sensors 21 and 22, which are respectively fixed outside the frame 11 in positions which correspond to the stroke limits of the gathered and extended configurations.
  • the sensors 21 and 22 are, for example, the Hall or reed types, which are commonly commercially available and are energized in the presence of a magnetic field.
  • These sensors are also connected so as to activate or not activate the motor means 18.
  • operation is as follows: when the Venetian blind 14 is moved, by means of the permanent magnet 20 associated therewith it energizes, as it passes, one of the two sensors 21 or 22, which act as stroke limits which transmit the power-off signal to the motor means 18.
  • the motor means are associated with the head of the frame 11.
  • the adjustment of the internal state of the light-blocking means in the double-glazing unit provided with the device according to the present invention is particularly precise and does not require in any way the provision of holes or other openings in the panes, which would cause difficulties in providing tightness in the passage regions.
  • the device according to the present invention in fact provides passage through the panes, in order to indicate the state and position of the light-blocking means, by means of an electromagnetic field generated by the magnet or magnets fixed to said light-blocking means; the external sensors then detect the presence of said magnetic field, performing the appropriate adjustments and actuations on the motor means.
  • the number of components is drastically reduced, improving both costs and production simplicity as well as aesthetic execution options, eliminating cumbersome and usually unaesthetic devices located outside the double-glazing unit.
  • the materials and the dimensions may be any according to requirements.
