Inverter switch is connected to a power source (8) and wired to the drive motor (3) mounted in a housing (10). A motor shut off control circuit (11) is positioned in a control box (6), which uses motor load to control the end of shutter movement.

Description

The invention relates to a shutter control device motorized comprising a box provided with a control reverser raising and lowering an apron, this reverser being connected to an electrical power supply and connected, wired, to the drive motor housed in a box accommodating the winding and unwinding mechanism of said apron, said engine being associated with management means for its operation and end-of-travel stop control unwinding and winding of the deck.

The present invention will find its application in the field motorized closing devices for the building, especially roller shutters.

It is more and more frequent to motorize the control opening and closing of roller shutters. So the most frequently encountered conceptions consist of what the drive motor, of a tubular form, takes position inside the winding tube around which comes roll up, in the open position of the roller shutter, the apron of the last. In fact, this motor acts on this tube winding, most commonly via a reducer, knowing that it is still associated with it, usually, a brake operating by lack of current allowing 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, the front of which is capable of deploying such a shutter motorized roller, the user has a control reverser raising and lowering the apron. This inverter takes position on a control box, which, according to installations, protrudes or is embedded in the construction wall.

In the most economical designs this inverter control is connected to the power supply circuit the house and is wired to the drive motor housed in the roller shutter box. Through elsewhere, in certain configurations, the boxes of control corresponding to several roller shutters of a 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, therefore more expensive designs, the command reverser is associated with the management unit of the operation of the drive motor inside the box roller shutter. This unit still receives a receiver for wireless, infrared, wireless remote control or other, through a transmitter defined by a box control which, as before, is arranged so accessible in the immediate vicinity of the door or window corresponding to the roller shutter to be ordered.

Note that, again, the same transmitter may be able to act on several roller shutters for a grouped order opening and closing. Depending on the solution adopted, this transmitter may be able to transmit signal remotely capable of being perceived by the receiver of several flaps or these can be connected together, particular by carrier current, so that an emission under form of a particular command from a transmitter can be interpreted as a grouped command and retransmitted, by the rolling shutter with which this specific is more specifically associated transmitter, to other roller shutters.

Therefore, again, the operation management unit of the shutter motor or the means interconnection of this rolling shutter with other shutters take position in a box housed in the shutter box wheelchair concerned, or even in a housing provided for this purpose at level of the masonry, in the immediate vicinity of this box.

About the engine operation management unit rolling shutter drive, it consists of in particular, by means making it possible to manage the stopping of the motor operation at the end of the opening stroke and shutter shutter closing.

Most often, such means of end-of-travel management of a roller shutter drive motor consist of electromechanical means. So it is more particularly known a mechanical system directly connected and driven by this motor, together with 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, order stop control switches.

Such electromechanical systems require adjustments meticulous and are, in fact, adjustable during use roller shutter. However, if the engine stops working roller shutter comes too late compared to the arrival at the end of the upper race of the apron, this can all simply lead to the rupture of this apron. Conversely, if, when the shutter closes, the engine stops too early, the automatic locking device may roller shutter curtain did not have time to activate.

Such a device, usually connecting the first blade of the apron to the winding shaft, normally results in to prevent that through an action exerted directly on this apron, it cannot be pushed back, manually and when of an attempted break-in, inside his box.

Other opening limit switch management devices and for closing a roller shutter are based on the principle of measurement of the load of the drive motor. Sleeping is to keep some of the parameters of the electric power supply to the motor to control its termination if, through these parameters, it is deduced that this load comes to exceed predefined values or if a load variation is recorded instantly important.

Again, these means of electronic management of operation of the motor and in particular of its limit switches, take position in a housed housing, either directly in the box of the roller shutter, either in a box specially fitted in masonry near the latter.

However, it is obvious that the majority of failures encountered in the operation of roller shutters result from a dysfunction of these management means at the end engine stroke. Also, the staff providing the service is systematically led to dismantling the roller shutter box in order to be able to access the faulty parts. We will note, moreover, that in most cases the fact of being able access to the roller shutter box is not enough and it is necessary to disassemble the entire drive mechanism, even extract the motor from its winding tube drive to repair. It is therefore a heavy and costly intervention that cannot be carried out only by qualified personnel.

Finally, it will also be observed that means of managing electronic type limit switches, based on the principle of engine load control, are fully able to replace a faulty electromechanical system.

In short, it would be particularly advantageous to be able to replace with such electronic limit switch systems faulty electromechanical management systems, everything simply 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 device for controlling motorized roller shutter comprising a box fitted with an inverter control of raising and lowering an apron, this reverser being connected to an electrical power supply and wired, connected to the drive motor housed in a box housing the winding and unwinding mechanism said deck, said engine being associated with management means of its operation and of the end-of-travel stop control command unwinding and winding of the deck, characterized by the fact that it is integrated into the control box, welcoming the up and down control reverser, a system electronic limit switch management training, in particular in the form of a measurement of the load of this motor, this system being connected, so wired, to the latter.

Finally, by going against the approach systematically adopted in this area of roller shutters which consisted in a search for total integration of the means of management of engine operation inside the box, in particular in order to limit assembly operations during the first installation of this roller shutter, the invention knew respond to the difficulties encountered during interventions after sale as part of a wired design that remains, for the time being, the most widespread, because the most economical.

Thus, through the present invention, the service after sale is able to remedy the majority of failures encountered without even intervening on the roller shutter itself and without using any stepladder, ladder or other.

Furthermore, if the substitution by a management system of electronic limit switch of an electromechanical system or mechanical failure was, until now, not envisaged in insofar as this necessitated the integration into the casing of a additional box or the arrangement of such a box in masonry, the present invention provides, finally, a solution to this problem. We will observe, in this regard, that such a limit switch management system, housed in the control box, is able to intervene in replacement to any type of system previously installed 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 definitive solution to the difficulties repetitive that it has encountered in the past with a system electromechanical limit switch management.

Furthermore, assuming that in a control device grouped of several roller shutters, these are connected by carrier current and that one of them, called a master, integrates a carrier current transmitter enabling, through it 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, again, integrated, according to the invention, in the housing of control accommodating the up and down control reverser lowering of the roller shutter deck.

In fact, such means of remote control by current bearer of several roller shutters are likely to generate failures in the operation of these components rolling, so that by facilitating their accessibility it makes easier repair interventions.

A design according to the invention also makes it possible to respond to a retrospective equipment problem with a house with group control of its roller shutters. Indeed, since in a wired type installation, the control unit, welcoming the up and down control reverser, rolling shutters is generally connected to the network supply of electrical energy to a dwelling, it is very easy to connect to this network a receiver or a carrier current transmitter which is precisely housed in this case.

Finally and as shown by the explanations which above, the present invention stems from an approach inventive through which we were able to question the established principles for the construction of a motorized roller shutter.

La figure 1 est une représentation du principe de base d'un dispositif de commande selon l'invention.

La figure 2 est une illustration de ce principe dans le cadre d'une commande groupée à distance de plusieurs volets roulants.

The invention will be better understood on reading the following detailed description relating to the appended 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 shutter control device 1 motorized roller 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 control, according to the case, the winding or unwinding of the deck 5 of this component rolling 2.

In this regard, the user has, in an accessible and near this rolling shutter 2, a control box 6. This contains an inverter 7 for controlling the rise and lowering of said deck 4, this reverser being connected to a electric power supply 8 and connected, so wired 9, to the drive motor 3. The latter and, so general, the entire winding mechanism and unfolding of the deck 5, takes position in a box 10 surmounting the opening corresponding to a door, window or similar equipped with said rolling shutter 2.

According to the invention, it is still integrated into the control unit 6 an electronic end-of-travel management system 11 engine 3. More particularly, such a system is presented under form of control means for stopping the operation of this motor 3 if a threshold value is exceeded motor load and / or exceeding a variation in this charge over a predefined period.

Thus, this determination of the load of an engine can, by example, to 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 wire connection 9 connecting it to said motor drive 3, housed in box 10, it is easy to provide, at this wired connection 9, the cables connection necessary for the operation of this electronic limit switch management 11. Also, it appears obvious way that such a system 11 does not complicate more the operations of assembly and pause of a shutter rolling equipped with a device 1 according to the invention.

Furthermore, if a rolling shutter is originally fitted with a mechanical and / or electromagnetic management system and / or electronic limit switches of the drive motor 3, system taking position in box 10, in the event of failure of the latter it is easy to inhibit it in order to replace with an electronic management system 11 of these purposes of races that are precisely housed in said housing 6.

In a more advanced embodiment and for the management of a group control of several roller shutters, it is still integrated in this control box 6 of a rolling shutter 2, a receiver 12 and / or a carrier current transmitter 13 enabling the through the control box 6 corresponding to a flap roller 2, configured as a 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 unit 6A, 6B, 6C of roller shutters 2A, 2B, 2C qualified as slaves. A such signal can then lead, as the case may be, to the command opening or closing of these roller shutters.

Obviously, this type of communication by carrier current allows to consider the command, from a master roller shutter 2, of the whole group 2, 2A, 2B, 2C of roller shutters of a dwelling or of subgroups.

Furthermore, in a control unit 6, 6A, 6B, 6C, can be housed a current receiver-transmitter assembly carrying so that each roller shutter 2, 2A, 2B, 2C can act, according to the case, as a master component or be able to retransmit, to such a master roller shutter 2, a information relating to the proper execution of a transmitted order since the latter. Visual signaling means and / or sound fitted to this master roller shutter 2 can thus retranslate, in a manner interpretable by the user, this information from slave roller shutters.

It is obvious that by grouping at the level of the box of command 6, further integrating the control command reverser 7 raising and lowering of an apron 5 of rolling shutter 2, all the components likely to constitute sources failure of such a shutter 2, it makes it easier after-sales service interventions.

However, as is also apparent from the description which precedes, this design offers many other possibilities again, in particular, that of being able to equip, a posteriori, installation of roller shutters for grouped operation of these roller shutters.

In addition, if until then one did not imagine replacing a mechanical limit switch management system or electromechanical by an electronic system, the solution according to the invention makes this possible and, with ease surprising.
