Definitions

  • the present invention relates to the field of venetian blinds.
  • Generally venetian blinds include a series of slats horizontal superimposed and individually supported by means flexible, wires for example, to be adjusted on one hand in inclination, on the other hand in height.
  • said flexible means comprise at least two scales respectively arranged in close proximity blade ends and each composed of two vertical strands interconnected with a regular pitch corresponding to that of the blades, by sleepers that support them.
  • the blade tilt adjustment is obtained by modifying by traction the relative height of the two aforementioned strands of the scales.
  • the height adjustment of the blades is obtained by modifying by traction the height of these two strands of the scales or by traction and adjustment in height of at least one auxiliary link, fixed for example on the lower blade.
  • control means offered to control the inclination of the venetian blind slats has a horizontal axis housed in the upper box of the blind, and fitted with coils on which are fixed the upper ends of the vertical strands of the scales support.
  • the two vertical strands of the same ladder are respectively rolled up and unrolled to change the tilt of the ladder crosspieces and consequently the inclination of the boards.
  • the aforementioned scales can constitute vertical belts driven in controlled movement You will find examples of such arrangements in documents EP-A-0 278 230 and WO-A-92/14024.
  • Control means have also been proposed in the form of belts or the like, housed in the upper casing of the awning and curved on a roller with a vertical axis.
  • said belts form two horizontal strands on which the upper ends are fixed vertical strands of the ladders. Again a controlled movement of belts leads to a descent of one of the ladder strands and an ascent symmetrical on the other side. Examples of such provisions can be found in documents US-A-3,795,266 and EP-A-567,571.
  • control means comprising a motorized means housed in the housing upper blind, which drives by a screw / nut system a rigid rod horizontal on which are hung, at distant points, the upper ends of vertical strands of scales.
  • the present invention now aims to provide new ways of controlling Venetian blinds.
  • the object of the present invention is in particular to provide means having a small footprint in order to limit in particular the height thereof and consequently the height of the upper housing required.
  • the present invention also aims to propose means simple on the one hand to improve reliability compared to systems known prior art and secondly to allow easy installation, including understood by non-specialized personnel, on a non-existing structure specially adapted to receive a Venetian blind.
  • a Venetian blind comprising a series of superimposed horizontal slats and individually supported by flexible composite ladders each of two vertical strands connected together by crosspieces which support the blades, the upper ends of said vertical strands passing through the wall of a box to be connected to it by means of blade tilt control, in the form of a control mounted in horizontal translation in the housing and on which are fixed the upper ends of the vertical strands, so symmetrical in relation to their passage through the wall of the housing, characterized by the fact that the blind also comprises means manual actuation of said control element mounted in the housing, which actuating means comprise a member capable of being mounted at displacement in a vertical glazing bead of the opening associated with the blind.
  • the actuator is connected to the control element by via hauling which defines a multiplication of race between the actuating member and the control element.
  • the actuator is mounted in translation in said glazing bead.
  • the case 20 can if necessary be integrated into the horizontal glazing bead of the opening associated with the blind.
  • the housing 20 houses an element of control 30 mounted in horizontal translation in the housing.
  • the upper ends 13, 15 of the strands vertical 12, 14, are fixed on the control element 30, so symmetrical about their passage through the wall 22 of the housing 20.
  • symmetrical is meant in the context of the present invention that the upper ends 13, 15 of the strands 12, 14, are fixed in points of element 30 located respectively on either side of passages 24, 26 formed in the wall 22 of the housing 20. This does not mean necessarily that the anchor points of the ends 13, 15 on the element 30 are located equidistant from the center of these passages 24, 26 in any position of the blind, for example in position horizontal blades.
  • the element of control 30 is formed by a flexible cable superimposed on the wall 22 and which passes at least substantially through the axes of two through passages 24, 26 formed in the wall 22 and through which the strands 12, 14 pass through this wall 22.
  • the strands 12 extend in a given longitudinal direction (to the right according to Figure 1) to their point of attachment to the control element 30, while the strands 14 extend in the opposite longitudinal direction (to the left along Figure 1) to their point of attachment to the same control element 30. It will therefore be noted that outside of the housing 20, the two strands 12, 14 define a plane transverse to the longitudinal direction of the housing 20, while in this box 20, the strands 12, 14 extend along a plane longitudinal which coincides with the longitudinal direction of this housing 20.
  • control element 30 is connected to means manual actuators which include at least one member mounted displacement in a vertical glazing bead of the opening associated with the blind.
  • the ends of the cable 30 pass through eyelets 28 formed in the ends of the wall 22.
  • the sections of the cable 30 which emerge at the outside of the case, vertically downwards, are housed respectively in the vertical glazing beads of the associated opening. These sections are referenced respectively 32 and 34 in Figure 1 attached.
  • the passages 24, 26 are formed of circular holes. And the upper ends 13, 15 of the strands vertical 12, 14 of the same scale 10 cross a common passage 24 or 25.
  • the dimension or diameter of these passages 24 and 26 is adapted to so that the gap between these strands 24, 26, at the crossing of these passage 24, 26, considered in a direction transverse to the direction longitudinal of the wall 22, may be of the order of magnitude of the thickness of the blades. Thanks to this arrangement, it will be understood that the blades can, in a maximum adjustment position, be placed in a position such that their width is perfectly vertical. We guarantee thus optimal concealment of the associated opening, using the blades (which is often far from being achieved with known prior devices).
  • these orifices for the passage of the strands 12, 14 may be oblong and not circular in revolution, for example with their great length transverse to the longitudinal direction of the wall 22.
  • the orifices 24, 26 and 28 for passage of the strands 12, 14 and of the cable 30 can be fitted with suitable fittings to avoid any deterioration of the latter during their sliding on the edge of said orifices.
  • the fixing of the ends 13, 15 of the strands 12, 14 on the element of control 30 can be carried out by any suitable means, for example at using a knot, bonding, welding, tightening a ring, or by any equivalent means.
  • control element 30 the portion of which housed in the box 20 is formed at least partially of a rigid element, such as a rod.
  • a rigid element such as a rod.
  • the part of this control element 30 which emerges outside of the box 20 and forms the aforementioned actuating member can be formed at less in part from a rigid structure, such as a rod.
  • the control element 30 housed in the box 20 can be associated with any motion conversion device controlled by an organ manual actuation fixed on a vertical glazing bead.
  • FIG. 2 the profile of a vertical element of carpentry, in 42 a glazing and in 44 a vertical glazing bead comprising a internal U 45 profile to serve as a guide at the ends of the blades of the awning shown diagrammatically under reference 46.
  • a vertical element of carpentry in 42 a glazing and in 44 a vertical glazing bead comprising a internal U 45 profile to serve as a guide at the ends of the blades of the awning shown diagrammatically under reference 46.
  • Such an arrangement is described for example in document FR-A-2 737 531. It presents in particular the advantage that the U 45 profiles form a baffle which opposes the passage of light on the side of the blind 46.
  • FIG. 2 We also distinguish in Figure 2 an actuating rod 36 mounted in translation in a housing 43 of the glazing bead 44 and fixed to a button 38 accessible at a vertical groove formed in the wall the glazing bead 44.
  • the upper end of the rod 36 can be connected to a flexible or a cable 30 forming a control element.
  • a translation vertical button 38 translates the control element 30 and therefore adjust the tilt of the blind slats.
  • the actuating member carried by the glazing bead can include a hose or cable connected to cable 30 (possibly extending it) whose lower end is wound on the axis of a button rotatably mounted on the glazing bead 44.
  • the actuating member 38 carried by the glazing bead 44 is connected to the control element 30 by means of a hauling 50 which defines a reduction in stroke between the body actuator 38 and control element 30.
  • drawers 56 and 58 mounted in translation in the box 20, again in the longitudinal direction of the housing 20. These drawers 56, 58 are connected together by a rod 57.
  • a connection is also defined between each cursor 52, 54 and a drawer 56, 58.
  • this connection is formed by a rope 60, 62 or a similar element the ends of which are fixed respectively on a cursor 52, 54 and in the vicinity of one end of the housing 20, each rope 60, 62 being folded back on itself in the form of a 180 ° loop around a roller or pin 51, 55 linked to a respective one of drawers 56, 58.
  • the ends 13, 15 of the strands 12, 14 of a ladder 10 are fixed to distance on a drawer 56, 58, as indicated previously.
  • a translation of amplitude D of the rod 36 causes a translation of the same amplitude D of the sliders 52, 54, but a D / 2 amplitude translation for drawers 56, 58 and by therefore for each strand of scale 12, 14.
  • the stroke reduction thus defined facilitates adjustment tilt angle of the blinds.
  • the present invention is not limited to two-fold embodiments scales 10 previously mentioned, but can also be applied to variants with a number of scales greater than 2, for example 3 scales, depending on the length of the blades involved.
  • the device hauling system 50 comprises at least one slider 52, 54 mounted in translation in the housing 20 and connected to the actuating member 37 and at least one drawer 56, 58 mounted in translation in the housing 20 and on which are fixed the upper ends 13, 15 of the vertical strands 12, 14 of the scales 10, the drawer 56, 58 and the cursor 52, 54 being connected by at least one rope 60, 62 of which the ends are fixed respectively on a slider 52, 54 and on the vicinity of one end of the housing 20, the rope 60, 62 being folded over it even in the form of a 180 ° loop around a roller or a pin 51, 52 linked to drawer 56, 58.
