Definitions

  • the present invention relates to a Venetian blind system for at least partially covering an opening, comprising several slats which are arranged substantially parallel to each other and which each comprise a rotation axle by means of which they are arranged in the opening so as to be rotatable with respect to their rotation axle, in which these rotation axles are arranged substantially in a plane, in which the Venetian blind system comprises a displacement mechanism for displacing of these rotation axles between an open position, in which all rotation axles are arranged substantially on one side of the opening and a closed position, in which the rotation axles are distributed substantially evenly across the opening and in which the Venetian blind system comprises a tilting mechanism for rotating the slats in a synchronous manner, comprising a first guide profile which extends laterally with respect to the slats and which is displaceable in a plane substantially at right angles to the plane of the rotation axles and comprising a first handle for each slat, one side of which is attached to an end of the rotation axle and the other side
  • Venetian blind systems are usually (but not exclusively) used as sunblinds or as an obscuration device.
  • the displacement of the rotation axles to the open position is coupled to the tilting of the slats to their open position and, conversely, the displacement of the rotation axles to the closed position is coupled to the tilting of the slats to their closed position, as is the case, for example, with the Venetian blind system from FR 1 284 011 A .
  • the present invention therefore also relates to such Venetian blind systems in which the tilting of the slats is not coupled to the displacement of the rotation axles of these slats, as is the case, for example, with the Venetian blind system from WO 2006/077543 Al .
  • the tilting movement of the slats is not coupled to the displacement movement of the rotation axles, as is the case, for example, with the Venetian blind system from WO 2006/077543 Al .
  • the first handle may at a certain point in time be at substantially right angles to the guide profile, after which it is not certain that the slats will be tilted further in the correct direction. In this case, the first handle reaches a so-called dead point.
  • the direction of the handle is considered to be the direction of the connecting line between the location where the handle is attached to the rotation axle and the location where the handle is guided in the guide profile, projected in a plane at right angles to the rotation axles and at right angles to the plane of the rotation axles.
  • the handle and the guide profile can now be arranged in such a manner and the movement of the guide profile can now be controlled in such a manner that the tilting movement of the slats takes place in a zone in which the handle does not reach its so-called dead point.
  • the handle of the Venetian blind system from WO 2006/077543 Al can describe a circle of rotation between +90° (horizontal) and -90° (opposite horizontal), in which these two extremes of the circle of rotation are the dead points.
  • arranging the handle and the guide profile in this way does result in a considerable number of limitations with regard to the design and position of the handle and the guide profile and with regard to the control of the guide profile.
  • a part of the tilting mechanism of the Venetian blind system from WO 2006/077543 Al always ends up in front of the rotation axles of the slats, as a result of which it is difficult, for example, to achieve a finished product in which the front side of the slats and the front side of the framed structure are in the same plane.
  • a Venetian blind system for at least partially covering an opening, comprising several slats which are arranged substantially parallel to each other and which each comprise a rotation axle by means of which they are arranged in the opening so as to be rotatable with respect to their rotation axle, in which these rotation axles are arranged substantially in a plane, in which the Venetian blind system comprises a displacement mechanism for displacing of these rotation axles between an open position, in which all rotation axles are arranged substantially on one side of the opening and a closed position, in which the rotation axles are distributed substantially evenly across the opening and in which the Venetian blind system comprises a tilting mechanism for rotating the slats in a synchronous manner, comprising a first guide profile which extends laterally with respect to the slats and which is displaceable in a plane substantially at right angles to the plane of the rotation axles and comprising a first handle for each slat, one side of which is attached to an end of the rotation axle and the
  • direction of the handle is considered to be the direction of the connecting line between the location where the handle is attached to the rotation axle and the location where the handle is guided in the corresponding guide profile, projected on a plane at right angles to the rotation axles and at right angles to the plane of the rotation axles.
  • the angle between the first and the second handle is therefore also the angle between their corresponding projections in the same plane at right angles to the rotation axles and at right angles to the plane of the rotation axles.
  • the first handle and the second handle are preferably fitted on the same end of the rotation axle.
  • both guide profiles are also arranged on another lateral side of the slats and this makes it necessary when driving the movement of both guide profiles, each at another end of the slats, to synchronize their movement by means of transmission means and/or by means of synchronized motors.
  • the first guide profile and the second guide profile are furthermore preferably arranged on the same side of the plane of the rotation axles.
  • Each guide profile of a specific embodiment of a Venetian blind system comprises a slot which extends substantially along the length of the guide profile, having an access opening which is situated on a side of the guide profile which extends substantially at right angles to the plane of the rotation axles, and each handle of such a Venetian blind system comprises a guide element which is arranged in the slot of the corresponding guide profile in a guided manner.
  • each guide element preferably comprises a guide wheel which is arranged in the corresponding slot so that it can roll.
  • the displacement mechanism of a particular embodiment of a Venetian blind system comprises a linkage guide which comprises linkage arms which are connected to one another in pairs in a crosswise and hinged manner by means of a centre hinge pin to form cross pieces, the various cross pieces being hingedly connected to one another at the ends of the linkage arms by means of outer hinge pins.
  • Such a linkage guide is also referred to as a pantograph structure.
  • Characteristic of the movement of the rotation axles by means of such a pantograph structure is the fact that the rotation axles remain at the same intermediate distance from one another in any position of said rotation axles.
  • the rotation axles of the slats are connected to or configured as outer hinge pins of the linkage guide.
  • the first guide profile and the second guide profile are preferably arranged on the same side of the plane of the rotation axles as that on which the linkage arms are mainly arranged.
  • the linkage guide is furthermore preferably arranged between the slats and the said guide profiles.
  • a Venetian blind system furthermore preferably comprises a slat guide profile which is arranged laterally with respect to the slats for guiding the movement of the rotation axles of the slats upon displacement thereof.
  • said linkage guide is furthermore preferably arranged between the slats and said slat guide profile.
  • a Venetian blind system preferably comprises drive means for driving the movement of the guide profiles in a synchronous manner upon displacement thereof.
  • These drive means preferably comprise a motor with a motor shaft, a first drive handle for converting the movement of the motor shaft to a movement of the first guide profile, and a second drive handle which is arranged at an angle with respect to the first drive handle for converting the movement of the motor shaft to a movement of the second guide profile.
  • the first and the second handle of each slat are arranged on the same end of the rotation axle, in which the first guide profile and the second guide profile are arranged on the same side of the plane of the rotation axles, and in which said access openings of the first guide profile and the second guide profile face each other, the first drive handle and the second drive handle are preferably arranged one behind the other between the first guide profile and the second guide profile.
  • the illustrated embodiment of a Venetian blind system (1) comprises slats (2a-g) which are arranged substantially horizontally and parallel to each other.
  • the slats (2a-g) each comprise a rotation axle (3a-g) which is fixedly connected to the body of the slats (2a-g) and which are rotatably arranged in the Venetian blind system (1).
  • the rotation axles (3a-g) of the slats (2a-g) of this Venetian blind system (1) extend in a vertical plane. It is obvious that the features of the invention can also be used to produce Venetian blind systems (1), in which the slats (2a-g) extend, for example, substantially vertically or in which the rotation axles (3a-g) are arranged in a horizontal plane or in a plane which is arranged at an incline.
  • the rotation axles (3a-g) can be pulled up between an open position, as illustrated in Fig. 4 , and a closed position, as illustrated in Figs. 1-3 and 7-13 .
  • the Venetian blind system (1) is provided with a linkage guide (15) on one side.
  • the linkage arms of this linkage guide (15) are connected to one another in pairs in a crosswise and hinged manner by means of a centre hinge pin to form cross pieces.
  • the various cross pieces are hingedly connected to each other at the ends of the linkage arms by means of outer hinge pins.
  • the Venetian blind system (1) is preferably provided with such a linkage guide (15) on each side.
  • the Venetian blind system (1) comprises pulling-up means for this purpose.
  • These pulling-up means may comprise, for example, a motor with pulling cable to be able to pull up the linkage guide and to lower it.
  • these pulling-up means may comprise, for example, a motor and a spindle to which the underside of the linkage guide is attached in a guided manner and is raised or lowered by rotating the spindle.
  • pulling-up means using, for example, chains, belts, gear wheel systems, etc. are conceivable.
  • the rotation axles (3a-g) of the slats (2a-g) serve as outer hinge pins on the front side of said linkage guide (15). In this way, the slats (2a-g) are attached to the front side of the Venetian blind system (1) in an aesthetic manner.
  • another additional outer hinge pin is provided between in each case two successive rotation axles (3a-g) of the slats (2a-g) on the front side of the linkage guide (15), so that two cross pieces of the linkage guide (15) are situated between two slats (2a-g).
  • the ends of the rotation axles (3a-g) on each side are arranged in a slot of a respective slat guide profile (6) in a guided manner.
  • the slats (2a-g) can furthermore be tilted in a synchronous manner by means of a tilting mechanism (4a-g, 5a-g, 7, 8, 9, 10, 11, 12, 13) between an open position (in which the tilt angle is 90°), in which the slats (2a-g) extend substantially at right angles to the plane of the rotation axles (3a-g) (see Figs. 4-5 and 7-9 ) and a closed position, in which the slats (2a-g) extend substantially along the plane of their rotation axles (3a-g) (see Figs. 1-3 ).
  • a tilting mechanism (4a-g, 5a-g, 7, 8, 9, 10, 11, 12, 13) between an open position (in which the tilt angle is 90°), in which the slats (2a-g) extend substantially at right angles to the plane of the rotation axles (3a-g) (see Figs. 4-5 and 7-9 ) and a closed position, in which the slats (2a-g)
  • the tilting mechanism (4a-g, 5a-g, 7, 8, 9, 10, 11, 12, 13) is provided on one side of the Venetian blind system (1) for the sake of simplicity of the drive mechanism and is situated as much as possible on the rear side of the Venetian blind system (1) for aesthetic reasons.
  • a first handle (4a-g) and a second handle (5a-g) are attached on the end of the rotation axles (3a-g) as part of said tilting mechanism (4a-g, 5a-g, 7, 8, 9, 10, 11, 12, 13).
  • These handles (4a-g, 5a-g) are attached to said rotation axles (3a-g) by their one end and are provided on their other end with a guide wheel (16, 17) which is arranged in a slot in a corresponding first guide profile (7) or second guide profile (8), respectively, so that it can roll.
  • This first guide profile (7) and this second guide profile (8) are arranged on a lateral side of the slats (2a-g) and displaceable in a plane substantially at right angles to the plane of the rotation axles (3a-g).
  • the tilting mechanism (4a-g, 5a-g, 7, 8, 9, 10, 11, 12, 13) is provided with a motor, with a motor shaft (13) and a first drive handle (9) and a second drive handle (11) for converting the movement of the motor shaft (13) into a movement of the first guide profile (7) and a movement of the second guide profile (8), respectively.
  • the handles (4a-g, 5a-g) are all provided on one side of the Venetian blind system (1), the guide profiles
  • first handles (4a-g) and the second handles (5a-g) are each provided on a different side of the slats (2a-g), then either additional transmission means have to be provided in order to be able to drive the movement of the corresponding guide profiles (7, 8) (which also have to be arranged on another side of the slats (2a-g)) in a synchronous manner, or two synchronised motors have to be provided.
  • the first drive handle (9) and the second drive handle (11) are arranged at an angle with respect to each other.
  • the first handle (4a-g) and the second handle (5a-g) of each slat (2a-g) are arranged at the same angle with respect to each other.
  • the direction of a handle (9, 11, 4a-g, 5a-g) is considered to be the direction of the connecting line between the points on the handle (9, 11, 4a-g, 5a-g) where it is attached or guided, projected on a plane at right angles to the rotation axles (3a-g) and at right angles to the plane of the rotation axles (3a-g).
  • the angle between respective handles (9, 11, 4a-g, 5a-g) is therefore also the angle between their corresponding projections in the same plane at right angles to the rotation axles (3a-g) and at right angles to the plane of the rotation axles (3a-g).
  • the guide profiles (7, 8) can be displaced in a plane at right angles to the plane of the rotation axles (3a-g) by means of the motor, the motor shaft (13) and the drive handles (9, 11). Due to the angle between the drive handles (9, 11), the movement of the second guide profile (8) takes place with a phase shift with respect to the movement of the first guide profile (7).
  • the handles (4a-g, 5a-g) on the slats (2a-g) the movement of the guide profiles (7, 8) is in turn converted into a tilting of the slats (2a-g).
  • the guide profiles (7, 8) of the illustrated Venetian blind system (1) are arranged on the rear side of the Venetian blind system (1), displaceable on one side of the plane of the rotation axles (3a-g).
  • the handles (4a-g, 5a-g) as well as the drive handles (9, 11) are arranged between the guide profiles (7, 8), one behind the other, viewed in the direction of the rotation axles (3a-g), as can clearly be seen in Fig. 14 . If both handles (4a-g, 5a-g) were to be in the same plane, the differently oriented handles (4a-g, 5a-g) would come into conflict with one another during stacking. In this case, the access openings to the slots of the guide profiles (7, 8) face each other.
  • the linkage guide (15) is arranged between the slats (2a-g) and the second guide profile (8). This arrangement could in principle also be reversed. However, the present arrangement has the advantage that the bending moment on the rotation axles (3a-g) is limited due to the short distance.
  • both the linkage guide (15) and the tilting mechanism (4a-g, 5a-g, 7, 8, 9, 10, 11, 12, 13) are situated behind the slats (2a-g) in the illustrated Venetian blind system (1), as is illustrated in Figs. 1-3 .
