Definitions

  • the invention relates to a motorized rolling shutter comprising an apron constituted by a juxtaposition of blades at least articulated with respect to each other and the ends of which move in lateral slides, this apron winding around and deploying from a shaft of winding inside which is housed a motor-drive reduction gear, of the tubular type.
  • this roller shutter can also be equipped with means delivering an electrical signal representative of the movement of the deck, and a unit for processing the electrical signal capable of intervening in the operation of the drive gear motor, in particular for controlling stopping it in the event of an obstacle.
  • the present invention will find its application in the field of closing devices, such as roller shutters.
  • this motorized rolling shutter comprises an apron winding around or deploying from a winding shaft which is rotated, in this case, by electric motor means and, in particular, a gear motor, of the tubular type, precisely housed in the winding shaft.
  • this winding mechanism of the roller shutter deck is generally placed in a box under which run slides for guiding, at the lateral ends of the blades making up the deck, this in the deployment or folding phase of the latter .
  • this rolling shutter is also equipped with means delivering an electrical signal representative of the movement of the deck, these means being constituted, essentially, by a pulley on which is wound a flexible element, such as a cord, the free end of which is connected to the final blade of the deck.
  • a pulley on which is wound a flexible element, such as a cord the free end of which is connected to the final blade of the deck.
  • elastic means ensuring the rewinding of the cord on the pulley during the winding of the deck.
  • a signal generator mechanically connected to the axis of the pulley and delivering an electrical voltage representative of the speed of rotation of the pulley.
  • this signal generator can preferably be in the form of a Hall effect sensor, such as a synchronous motor used as a generator.
  • this logic unit comprises means for sampling the electrical signal delivered by the signal generator.
  • the main drawbacks encountered through a rolling shutter come mainly from the structure of the means delivering an electrical signal representative of the movement of the deck. More specifically, such means are first of all bulky, insofar as they require the installation, at the level of the roller shutter box, of a pulley on which is capable of winding the transmission element constituted by the cord. In addition, this pulley must be associated with the signal generator in the form of a synchronous motor. In fact, this assembly takes position at the end of the axis of winding of the deck which is not always possible due to lack of space.
  • the mechanical connection connecting the final blade of the deck to the pulley is a source of operating problems.
  • the cord constituting this transmission element can, at any time, become blocked by being jammed, either at the level of the rolling shutter itself, or at the level of the door or window closed by this rolling shutter. Not to mention that this cord is accessible to the user, which naturally increases the risk of incidents.
  • a roller shutter which, as a means delivering an electrical signal representative of the movement of the deck uses, first of all, means for detecting the translational movement linear of the deck in the form of a roller rubbing on the surface of said deck and transforming the linear movement movement of the shutter into a rotational movement.
  • coding means are provided in the form of a coding wheel provided with a number of peripheral and radial notches which is integral with said friction roller and driven by the latter. With this coding wheel is associated a system for capturing the information delivered by the latter, in particular an optoelectronic sensor, which is able to detect the passage of the notches of said coding wheel and to deliver an electrical signal. This is then processed at a central processing unit.
  • a sensor for the presence of the roller shutter deck to detect its arrival in the high position is also a sensor for the presence of the roller shutter deck to detect its arrival in the high position.
  • This sensor is produced in the form of a spring-loaded roller, bearing on the surface of the apron and escaping from this surface at the end of the upper stroke to actuate a micro contact controlling the stopping of the gear motor for driving the apron.
  • the present invention aims to remedy all the drawbacks encountered through the prior art as described above, this through a motorized roller shutter of simple design, while being particularly safe, both on the plan of longevity than that of security itself.

  • the movement of the carriage is controlled constantly and not discontinuously. This makes it possible to observe, more simply, a change in the operation of the roller shutter, for example, due to the presence of an obstacle. The result is a less complex and therefore less expensive processing unit.
  • this simplicity of design is found in all of these means capable of delivering an electrical signal representative of the movement of the deck.
  • they can advantageously constitute means for controlling the operation of the gear motor at the end of the upper and lower travel of the deck. More specifically, it can be provided that when reaching the end of the high or low stroke, the permanent magnet disappears in front of the inductive sensor, at the upper or lower end of the latter, causing the geared motor to stop.
  • a permanent magnet in particular to one of the blades constituting the lower part of the apron, makes it possible to envisage yet in another way an easy control of this stopping of the operation of the drive gear motor.

  • the present invention relates to a motorized roller shutter 1, this comprises an apron 2 formed by a juxtaposition of blades 3, at least articulated with respect to each other. In fact, very frequently, these blades 3 are also telescopic with respect to each other, so that the deck 2 can adopt an openwork position, corresponding, precisely, to the maintenance of these blades 3 separated from each other.
  • This apron 2 is wound around or deployed from a winding shaft 4 mounted for rotation, generally in a box surmounting the opening arranged in a construction and which should be closed by means of this motorized shutter 1. Inside this winding shaft 4 is housed a tubular type drive motor reducer 5.
  • This motorized roller shutter 1 is further equipped with means 8 capable of delivering an electrical signal representative of the movement of the deck 2, as well as a processing unit 9 of this electrical signal capable of acting on the operation of the motorcycle. drive reducer 5, for example to control the stopping of the latter in the presence of an obstacle on the passage of the deck 2.
  • these means 8 capable of delivering an electrical signal representative of the movement of the deck 2, are constituted by at least one inductive sensor 10 extending, at least in part, along the path followed by the apron 2, in particular along a lateral slide 7, so that it is able to create an electromotive force under the influence of the passage, in front of this inductive sensor 10, of a permanent magnet 11 associated with the lower part 12 of the apron 2.
  • this electromotive force produced by the inductive sensor 10 is zero when there is no movement of the permanent magnet 11 and, consequently, of the apron 2. Furthermore, it is positive when moving the deck in one direction and negative when this deck 2 is moving in the opposite direction.
  • this processing unit 9 stops the operation of the drive gear motor 5, as soon as it notes the passage of a current in this drive gear motor 5 and the absence of voltage across the terminals of the inductive sensor 10.
  • this unit of treatment 9 may have the function of stopping the operation of the drive geared motor 5 if it is observed during the deployment of the deck 2, an inversion of the electromotive force and, consequently, of the voltage at the terminals of the inductive sensor 10, without this inversion being at the origin of a command to invert the movement of the deck 2 via an action voluntary use on control means 13 systematically equipping such a motorized rolling shutter 1.
  • the inductive sensor 10 is in the form of an inductor whose terminals are connected to the processing unit 9 and which is wound on a magnetic support 14, more particularly a hollow metal tube of small section.
  • this section of the magnetic support 14 is reduced to such an extent that this inductive sensor 10 can take position inside a slide 7 while allowing the displacement, in the latter, of the ends 6 of the blades 3 making up the deck 2
  • a slide 7 is in the form of a "U" section profile comprising an external wall 15, an internal wall 16 and a bottom 17.
  • the external 15 and internal 16 walls have sealing brushes 19 having a thickness 20 determining the maximum section that the inductive sensor 10 can take.

  • the permanent magnet 11 of the anisotropic ferrite type, it is installed inside and at the end 6, with respect to an inductive sensor 10, of a blade 3 composing the lower part 12 of the deck 2 In fact, it is advantageous to implant this permanent magnet 11 in the last blade 3A or the penultimate blade 3B of the deck 2.
  • inductance coil in its lower part 21, with a greater number of turns in order to obtain an electrical signal of greater amplitude, in order to control the arrival of the lower end of the curtain 2 and allow complete closure of the motorized shutter 1.
  • such means 8 capable of delivering an electrical signal representative of the movement of the deck 2, in accordance with the invention, also allow a simplification of the management of the operation of the drive geared motor. 5, in particular for the latter stop command either when the apron 2, deployed, arrives at the low end of the stroke or, wound, comes at the high end stroke.
  • the length of the inductive sensor 10 can be determined so that when it is no longer under the influence of the permanent magnet 11, the processing unit 9 detects an absence of electromotive force and, consequently, the arrival in the high position and / or in the low position of the deck 2. It is then ordered to stop the drive geared motor 5, this immediately or tempered.
  • a such a permanent magnet 11 may advantageously constitute the remote control means for switches 22, 23, of the flexible blade switch (ILS) or Reed bulb type, to cause the operation of the drive gear motor 5 to stop, when the deck 2 is deployed and at the low end of travel or wound at the high end of travel. More precisely, such switches 22, 23 are installed, under these conditions, either on a slide 7, or inside the latter, so that when the permanent magnet 11 is fitted, for example, the end 6 of a blade 3A, 3B there is a stop in the operation of the geared motor drive 5.

  • the means intended to deliver an electrical signal representative of the movement of the deck are simple to make, and negligible space. They are however particularly reliable, since they are not very sensitive to external aggressions.
  • association, with the apron, of a permanent magnet allows a particularly simplified management of the operation of the drive gear motor which, consequently, proves to be less complex.
