Definitions

  • the present invention relates to a motorized blind comprising a winding shaft and an apron integral with the winding shaft and whose deployment of the deck is able to be interrupted when it encounters an obstacle.
  • Known motorized blinds with adjustable blades are installed along the bay windows. They comprise on the one hand a winding shaft mounted in an upper part of the bay and a set of stackable blades having a terminal support blade capable of stackably receiving the other blades of said set of blades.
  • the winding shaft is controllable in rotation by means of an electric motor.
  • the blinds comprise retaining means for retaining each of said blades and drive ribbons, usually called lacettes, and connecting said terminal support blade and the winding shaft freely passing through the other blades.
  • the ribbons are able to be wrapped around the winding shaft, while the free support blade exerts on them a tension under the effect of gravity.
  • the winding shaft is intended to be rotated to unwind the ribbons and cause the vertical drive of the terminal support blade in translation between a close position and a position remote from said shaft in which said retaining means retain from close to near said other blades facing said bay, while said final blade is suspended from the ribbons.
  • the motorized blind further comprises a stop mechanism comprising a control rod pivotally mounted in a direction substantially parallel to the winding shaft and adapted to come into contact with at least one of the ribbons.
  • a stop mechanism comprising a control rod pivotally mounted in a direction substantially parallel to the winding shaft and adapted to come into contact with at least one of the ribbons.
  • the disadvantage of this device lies in the reliability of the stop mechanism and the rotation stop control of the winding shaft.
  • the control rod has a certain flexibility which requires a complete release of the ribbon for the switch is actuated, and efforts to exert on it to control the stopping of the electric motor are relatively important.
  • the motorized blind has only one stop mechanism for a single ribbon winding, and the final blade encounters an obstacle next to another ribbon winding, not equipped, it will take several seconds before that said other ribbon winding finally feels the voltage anomaly; the final blade then being stopped while it has a very pronounced slope, which is both unsightly and risky.
  • We can of course overcome this disadvantage by equipping each of the ribbon windings around the winding shaft of a stop mechanism, but we find us quickly having to manage many electrical conductors, including microswitches and a box electric. This significantly increases the price of the product.
  • a problem that arises and that aims to solve the present invention is to provide a motorized blind including a stop mechanism more reliable and more economical, capable of interrupting the movement of the final blade, regardless of the location where is the obstacle.
  • the present invention provides a motorized blind according to claim 1.
  • a feature of the invention lies in the implementation of a stop mechanism, maintained in a fixed position along the winding shaft, which does not act on a switch to cut off the power supply.
  • the drive motor of the shaft but which comes directly into engagement with the shaft to lock it mechanically and thus interrupt the electric motor.
  • the latter is equipped, for example, with a device for measuring the rotational speed of its rotor, and when this speed undergoes a sudden change, in this case a deceleration, the power supply is then cut off instantly and the engine stopped.
  • the winding shaft is instantly mechanically locked in rotation and it is this blockage which causes the stop of the electric motor which drives it. Therefore, the reliability of the stop mechanism, and hence the efficiency of the rotational stop of the winding shaft is large. Also, as soon as the lower ballast meets an obstacle, and the windable portion relaxes, the winding shaft whose rotation allows the deployment of the deck, is instantly immobilized.
  • the rollable portion relaxes, not only at the end of the race of the lower ballast border, but when the lower ballast border meets an obstacle, in any of the positions between a close position of the shaft winding and a position away from the winding shaft.
  • Said stop mechanism is located outside said winding shaft, while said at least one windable portion extends between said stop mechanism and said winding shaft. In this way, it is easier to detect the loosening of the roll-up part when it occurs, whatever the position of the lower ballast border.
  • said winding shaft comprises a tubular member adapted to receive a tubular motor inside said tubular member for driving said tubular member in rotation.
  • the motorized blind can not only be produced at an advantageous cost, because these tubular motors associated with a tubular member are produced in large series for many other applications and therefore at an advantageous cost. They are used in particular for shutter type applications. They are also more compact.
  • motorized blinds according to the prior art, are usually equipped with a central motor dual output and therefore double reducer, which makes them on the one hand more complex, and on the other hand more expensive. In addition they are larger, and therefore the housing that hosts such a type of engine must also be of a larger volume.
  • the winding shaft advantageously has a catching tooth intended to cooperate with said stop mechanism to mechanically lock said winding shaft in rotation.
  • the stop mechanism advantageously comprises a movable feeler member having a first fixing end and a first contact end opposite said first fixing end and able to come into contact with said at least one rollable part.
  • the first fixing end is preferably pivotally mounted along an axis substantially parallel to said winding shaft.
  • the feeler member pivots, for example in a cradle traversed by the winding shaft, which cradle is mounted in a fixed position in the aforementioned casing.
  • the contact end of the feeler member, against which the rollable portion is frictionally driven, extends substantially perpendicular to the center of the winding shaft, while the fastening end extends in a position offset laterally from the center of the shaft.
  • the probe member thus extends in arc opposite the winding shaft.
  • said stop mechanism comprises a return spring of said feeler member for driving said feeler member in motion when said at least one rollable portion relaxes.
  • said feeler member is pivotally driven when said at least one rollable portion expands.
  • the rollable portion when it is under tension under the weight of the lower ballast edge, it then exerts a force on the contact end of the feeler member which is then held in a pivoted position where its contact end is removed of the winding shaft and in which the return spring is compressed.
  • the rollable portion relaxes and the return spring causes the pivoting of the feeler member and bringing the contact end of the winding shaft. It is this pivoting of the feeler member that allows the stop mechanism to engage the winding shaft to mechanically lock it.
  • said stop mechanism comprises a movable locking member having a second fixing end and a second end of contact opposite to said second fixing end adapted to engage said winding shaft.
  • the second fixing end of the locking member is pivotally mounted along an axis substantially parallel to said winding shaft.
  • the feeler member and the locking member form two distinct pieces, and said feeler member is intended to be driven in motion to come into contact with said locking member. in order to drive said locking member in motion.
  • said feeler member pivots to come into contact with said locking member so as to cause said locking member which pivots in turn.
  • feeler member and the locking member may also, according to yet another embodiment, be movably mounted in translation to perform functions identical to the stop mechanisms. It is also envisaged that one is mobile in translation while the other is pivotal.
  • said apron comprises, on the one hand, a set of blades having a terminal support blade forming said lower ballast border, and on the other hand at least one drive ribbon passing through said other blades and forming said at least one rollable portion.
  • said shaft has a circular track for receiving said at least one coiled drive tape.
  • the circular track is formed in the bottom of a grooved pulley, so as to guide perfectly the winding of the tape on itself.
  • the apron may also consist of a fabric adapted to be wound around the winding shaft, and the rollable part adapted to cooperate with the stop mechanism is formed by one of the side edges. of said canvas.
  • the motorized blind further comprises: adjustable retaining means comprising a cord and an angular segment integral with said cord, together forming a loop around said winding shaft, said angular segment being able to be angularly driven by friction by said shaft to adjust the orientation of said blades; and also a mobile locking cap for blocking said angular segment with respect to said winding shaft in an intermediate angular position corresponding to a determined orientation of said blades; and finally, an unlocking element for driving said movable locking cap and for causing the release of said angular segment when said at least one driving tape is unwound.

  • a mobile locking cap for blocking said angular segment with respect to said winding shaft in an intermediate angular position corresponding to a determined orientation of said blades
  • the Figure 1 partially illustrates a winding shaft comprising a tubular member 10 adapted to receive inside a tubular motor not shown.

  • the movable hood 22 has in each of its corners, a fastening pin 19 and the fixing studs 19 of the movable cowl 22 are respectively engaged in an oblong orifice 23. Thanks to the oblong holes which extend in the lateral edges of the upper window 17, in directions which cut the tubular member 10, the cover 22 is movable in translation between a close position and a position away from the functional sleeve 18, while remaining prisoner of the cradle 16.

  • the latter has an axial inner rib 30 intended to engage inside the longitudinal groove 20 of the tubular member 10 illustrated in FIG. Figure 1 , so that the rotational movement of the tubular member 10 induces the rotation of the functional sleeve 18 and causes the unwinding of the tape and thus the drive of the terminal support blade in translation opposite the tubular member 10.
  • the functional sleeve 18 has, on the one hand, a groove 32 of trapezoidal axial section, adjacent to the pulley formed by the two coaxial ribs 26, 28, and which will be described below in more detail on the Figure 6 and on the other hand a truncated rib 34 circular.
  • This truncated rib 34 constitutes a rock wheel and it extends in a plane substantially perpendicular to the axis of the functional sleeve 18 and the tubular member 10, opposite the pulley formed by the two coaxial ribs 26, 28 with respect to the trapezoidal groove 32. It defines a first free end 36 forming a hooking tooth projecting from the functional sleeve 18 with two opposite reinforcing cheeks 38, 40, on each side and joined by a bridge 42 which extends in an axial direction. Opposite the first free end 36 forming a hooking tooth, the truncated rib 34 has a second free end 44 chamfered and able to form ramp. Also, the truncated rib 34 has a notch 45 between its two opposite free ends 36, 44.
  • the motorized blind comprises a stop mechanism 46 installed along the functional sleeve 18, and integral with the cradle 16 not shown in this Figure 2 .

  • the feeler member 48 has a heel 58 in which is housed a return spring 60 adapted to extend behind the feeler member 48 to abut against the inside of the cradle 16. Therefore, the feeler member 48 is rotated by the return spring 60 for driving the first contact end 54 towards the functional sleeve 18.
  • the locking member 50 has a second fastening end 62 pivotally mounted on the inside of the cradle 16 around a locking member axis 64 substantially parallel to the feeler member axis 56.

It will be explained hereinafter, with reference to FIG. Figure 4 that such a characteristic is advantageous when the functional sleeve 18 is rotated in the opposite direction.
  • the ribbon 24 relaxes and relaxes while the tubular member and the functional sleeve 18 continue their rotation.
  • the relaxation of the drive ribbon 24 occurs as soon as the terminal support blade encounter an obstacle between its position close to the functional sleeve 18 and its end-of-travel position, separated from the functional sleeve 18.
