Description

1 2811703

  The invention relates to a motorized roller shutter control device comprising a housing provided with a control switch for raising and lowering an apron, this reverser being connected to an electrical energy supply and connected, by wire, to the drive motor housed in a box accommodating the winding and unwinding mechanism of said deck, said motor being associated with means for managing its operation and for controlling stop at the end of the unwinding and winding stroke

of the apron.

  The present invention will find its application in the field of motorized closing devices for the building, in particular

roller shutters.

  It is more and more frequent to motorize the opening and closing control of roller shutters. Thus, the designs that are most frequently encountered consist in that the drive motor, of a tubular shape, takes position inside the winding tube around which comes to wind,

  in the open position of the roller shutter, the latter's apron.

  In fact, this motor acts on this winding tube, most frequently via a reducer, knowing that it is still associated therewith, usually, a brake operating by lack of current making it possible to immobilize in rotation this winding tube and, therefore, said apron, either at the end of the opening or closing stroke, or in any position

controlled by the user.

  In this regard, in the immediate vicinity of the door or window, at the front of which is capable of deploying such a motorized roller shutter, the user has an inverter for raising and lowering the curtain. This inverter takes position at a control unit, which, depending on the installation, is

  protrudes or is embedded in the wall of the building.

  In the most economical designs, this control inverter is connected to the electrical power supply circuit of the house and is connected by wire to the drive motor housed in the roller shutter box. In addition, in certain configurations, the control boxes

2 2811703

  corresponding to several rolling shutters of a home are connected to a general control, allowing the user to ensure, as the case may be, the opening or closing simultaneously of

all of these roller shutters.

  In more elaborate and therefore more expensive designs, the control reverser is associated with the unit for managing the operation of the drive motor inside the roller shutter box. This unit also receives a receiver for a non-wired remote control, of the radio, infrared or other type, through a transmitter defined by a control unit which, as before, is arranged in an accessible manner in the immediate vicinity of the door or window corresponding to the shutter

rolling to order.

  Note that, here again, the same transmitter may be able to act on several roller shutters for a grouped opening and closing command. Depending on the solution adopted, this transmitter may be able to transmit a remote signal capable of being perceived by the receiver of several roller shutters or these may be connected together, in particular by carrier current, so that a transmission in the form of a particular command from a transmitter can be interpreted as a grouped command and retransmitted, by the rolling shutter with which this transmitter is more specifically associated, to the other rolling shutters. Consequently, here again, the unit for managing the operation of the roller shutter motor or the means of intercommunication between this roller shutter and other shutters take up position in a box housed in the box of the roller shutter concerned, or even in a housing provided for this purpose at the masonry, at

  immediate proximity of this box.

  With regard to the unit for managing the operation of the motor for driving a rolling shutter, it consists, in particular, of means making it possible to manage the stopping of the operation of the motor at the end of the opening stroke and of

  shutter shutter closing.

  Most often, such end of stroke management means of a shutter drive motor consist of electromechanical means. Thus, it is more particularly known a mechanical system directly connected and driven by this motor, at the same time as the roller shutter deck. This mechanical system has the consequence, beyond a certain number of motor rotations, both in the direction corresponding to the opening and closing of the roller shutter curtain, to control switches

stop command.

  Such electromechanical systems require meticulous adjustments and are, in fact, adjustable during use of the roller shutter. However, if the shutdown of a rolling shutter motor stops too late compared to the arrival at the top end of the deck, this can quite simply lead to the break of this deck. Conversely, if, when the shutter closes, the engine stops too early, the automatic locking device of the roller shutter deck may not have

had time to get activated.

  Such a device, usually connecting the first blade of the deck to the winding shaft, normally has the consequence of preventing that by means of an action exerted directly on this deck, the latter cannot be pushed back, manually and when

  of an attempted break-in, inside his box.

  Other devices for managing the opening and closing limit switches of a shutter are based on the principle of measuring the load of the drive motor. In short, it is a question of keeping under control some of the parameters of the electric power supply of the motor to control its stopping if, through these parameters, it is deduced therefrom that this load comes to exceed predefined values or else if it is registered,

  instantly, a large load variation.

  Again, these means of electronic management of the operation of the motor and in particular of its limit switches, take up position in a housing housed, either directly in the casing of the rolling shutter, or in a specially fitted housing.

  in the masonry near the latter.

4 2811703

  However, it is obvious that the failures mainly encountered in the operation of roller shutters result from a malfunction of these management means at the end of the engine stroke. Also, the personnel providing the service is systematically required to dismantle the roller shutter box in order to be able to access the faulty parts. Note, moreover, that in most cases, being able to access the roller shutter box is not enough and it is necessary to dismantle the entire drive mechanism, or even extract it from its tube. winding up the drive motor for repair. It is therefore a heavy and costly intervention which

  can only be carried out by qualified personnel.

  Finally, it will also be observed that electronic end-of-travel management means, based on the principle of controlling the motor load, are perfectly capable of

  replace a faulty electromechanical system.

  In short, it would be particularly advantageous to be able to replace defective electromechanical management systems by such electronic limit switches.

  by rendering them inoperative.

  The present invention aims to provide a solution to

  all of the above constraints.

  To this end, the invention relates to a motorized shutter control device comprising a housing provided with an inverter for raising and lowering an apron, this inverter being connected to an electrical energy supply and connected, wired way, to the drive motor housed in a box accommodating the winding and unwinding mechanism of said deck, to said motor being associated with means for managing its operation and for controlling stop at the end of the unwinding race and winding of the deck, characterized in that it is integrated into the control unit, housing the up and down control reverser, an electronic end-of-stroke management system for the drive motor, in particular in the form of '' a measure of the load of this motor, this system being

  wired to it.

2811703

  Finally, by going against the approach systematically adopted in this field of roller shutters which consisted in a search for total integration of the means for managing the operation of the engine inside the box, in particular with the aim of limiting the assembly operations during the first installation of this roller shutter, the invention was able to respond to the difficulties encountered during after-sales interventions within the framework of a wired design which remains, for the time being, the most

widespread because the most economical.

  Thus, through the present invention, the after-sales service is able to remedy the majority of the failures encountered without even intervening on the rolling shutter itself and without doing

  use of any stepladder, ladder or other.

  Furthermore, if the replacement by an electronic end-of-travel management system of a faulty electromechanical or mechanical system was, until now, not envisaged insofar as this required the integration in the box of an additional box or even the arrangement of such a housing at the level of the masonry, the present invention finally provides a solution to this problem. It will be observed, in this regard, that such a limit switch management system, housed in the control box, is able to intervene as a replacement for any type of system previously implanted in the box, therefore, not only mechanical or electromechanical, but also, why not,

electronic.

  In short, through the present invention it is possible to offer a user a final solution to the repetitive difficulties that he may have encountered in the past, with a system of

  electromechanical limit switch management.

  Furthermore, assuming that in a grouped control device for several roller shutters, these are connected by carrier current and that one of them, called master, integrates a carrier current transmitter making it possible, by its intermediary, to control the opening and closing of the other roller shutters which are then provided with a carrier current receiver, said carrier current transmitter and / or carrier current receiver is there

6 2811703

  further, integrated, according to the invention, in the control box accommodating the up and down control reverser of the

roller shutter deck.

  In fact, such remote control means by carrier current of several roller shutters are liable to generate failures in the operation of these roller shutters, so that by facilitating their accessibility, it is easier to

repair work.

  A design according to the invention also makes it possible to respond to a problem of equipment, a posteriori, for a house with a group control of its roller shutters. In fact, since in a wired type installation, the control unit, housing the up and down control inverter, rolling shutters is generally connected to the electrical energy supply network of a dwelling, it is very easy to connect to this network a receiver or a carrier current transmitter that we

  comes precisely to be housed in this case.

  Finally and as appears from the foregoing explanations, the present invention stems from an inventive step through which we have been able to question the principles

  workbenches for the construction of a motorized roller shutter.

  The invention will be better understood on reading the description

  of detail which will follow and accompanied by the attached drawings in which: - Figure 1 is a representation of the basic principle of a control device according to the invention; - Figure 2 is an illustration of this principle in the context of a group remote control of several roller shutters. Thus, the invention relates to a device 1 for controlling

motorized roller shutter 2.

  More particularly, such a rolling shutter 2 comprises a motor 3, very often of tubular shape, defined suitable for ensuring the rotation of a winding tube 4 and controlling, as the case may be, the winding or unwinding of the deck 5 of this strand

rolling 2.

7 2811703

  In this regard, the user has, in an accessible manner and near this rolling shutter 2, a control unit 6. This contains an inverter 7 for controlling the ascent and descent of said deck 4, this inverter being connected to a supply of electrical energy 8 and connected, in a wired manner 9, to the drive motor 3. The latter and, in general, the whole of the mechanism for winding and unwinding the deck 5, takes position in a box 10 overcoming the opening corresponding to

  a door, window or the like equipped with said roller shutter 2.

  According to the invention, there is also integrated into the control unit 6 an electronic end-of-travel management system 11 for the motor 3. More particularly, such a system is in the form of means for controlling the stop of the operation of this motor. 3 in the event of detection of the exceeding of a threshold value of the engine load and / or of the exceeding of a variation of this load on a

predefined duration.

  Thus, this determination of the load of a motor can, for example, be deduced from the measurement of the phase shift of the signals corresponding to some of the current and / or voltage parameters that

  can be taken from the terminals and / or inside the motor 3.

  In fact, insofar as the control box 6 comprises, in all cases, a wired connection 9 connecting it to said drive motor 3, housed in the box 10, it is easy to provide, at this wired connection 9, the connection cables necessary for the operation of this electronic end-of-travel management system 11. Also, it is obvious that such a system 11 does not further complicate the assembly and pause operations of a roller shutter fitted with

  device 1 according to the invention.

  Furthermore, if a rolling shutter is originally equipped with a mechanical and / or electromagnetic and / or electronic management system for the limit switches of the drive motor 3, system taking position in the box 10, in case of failure of the latter it is easy to inhibit it in order to replace it with an electronic management system 11 of these limit switches which have just

  precisely lodge in said control box 6.

8 2811703

  In a more advanced embodiment and for the management of a grouped control of several rolling shutters, it is still integrated in this control unit 6 of a rolling shutter 2, a receiver 12 and / or a carrier current transmitter 13 allowing , through the control unit 6 corresponding to a rolling shutter 2, configured as master, to transmit, on the electrical power supply network 8 to which it is connected, a signal capable of being interpreted as a command grouped by the receiver 12 integrated into the control box 6A, 6B, 6C of roller shutters 2A, 2B, 2C qualified as slaves. Such a signal can then lead, as the case may be, to the command to open or close

these roller shutters.

  Obviously, this type of communication by carrier current makes it possible to envisage the control, from a master roller shutter 2, of the entire group 2, 2A, 2B, 2C of roller shutters of a

  housing or even sub-groups.

  Furthermore, in a control box 6, 6A, 6B, 6C, can be accommodated a receiver-transmitter current carrier assembly so that each roller shutter 2, 2A, 2B, 2C can act, as the case may be, as a shutter master or be able to retransmit, to such a master roller shutter 2, information relating to the proper execution of an order transmitted from the latter. Visual and / or audible signaling means equipping this master roller shutter 2 can thus retranslate, in an interpretable manner by the user,

  this information from the slave roller shutters.

  It is quite obvious that by grouping together at the level of the control box 6, also integrating the inverter 7 for raising and lowering an apron 5 of a roller shutter 2, all of the components likely to constitute sources of failure of such a rolling shutter 2, it makes it easier for the interventions of the

after sales service.

  However, as is also apparent from the description which

  precedes, this design offers many other possibilities, in particular that of being able to retrofit an installation of rolling shutters with an operation management

group of these roller shutters.

9 2811703

  Furthermore, if until then we did not imagine replacing a mechanical or electromechanical limit switch management system with an electronic system, the solution according to the invention makes this

  possible and with surprising ease.

  Although the invention has been described with reference to a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to the forms, materials and combinations of these. various elements, without

  for this to move away from the framework and the spirit of the invention.
