Description

The invention relates to a shutter control device motorized having a housing provided with a control inverter up and down an apron, this inverter being connectable to a power supply and likely to be wired to the motor of training housed in a housing housing the mechanism winding and unwinding said apron, said engine associated means of management of its operation and stop command at the end of the unwinding run and winding the apron.

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

It is more and more common to motorize the command opening and closing shutters. Thus, The most commonly encountered conceptions consist of what the drive motor, tubular shape, takes position inside the winding tube around which comes to wind up, in the open position of the shutter, the apron of the last. Actually, this motor is acting on this tube winding, most frequently through a reducer, knowing that he is still associated, 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 in any position ordered by the user.

In this regard, in the immediate vicinity of the door or window, the front of which is able to deploy such a component motorized wheel, the user has a control inverter of ascent and descent of the apron. This inverter takes position at the level of a control box, which, according to the installations, is projecting or is embedded in the wall of construction.

In the most economical designs as described, particular, in DE 39 33 66, this inverter of control is connected to the power supply circuit electrical house and is wired connected to the drive motor housed in the casing of the shutter. By elsewhere, in certain configurations, the enclosures control corresponding to several rolling shutters of a dwelling are connected to a general control, allowing the user to ensure, as the case, the opening or closing simultaneously of all these rolling shutters.

In the more elaborate designs, so more expensive, the control inverter is associated with the management unit of the operation of the drive motor inside the box shutter. This unit still receives a receiver for a wireless remote control, of the radio type, infrared or other, through a transmitter that defines a box of command which, just 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 issuer may be able to act on several shutters for a group order opening and closing. According to the solution adopted, this transmitter may be able to emit a signal remotely able to be perceived by the receiver of several shutters wheelchairs or these can be connected to each other, in particular power-line, so that an emission under form of a particular command from a transmitter can be interpreted as a group order and retransmitted by the roller shutter which is more specifically associated with this transmitter, to the other shutters.

Therefore, again, the functional management unit shutter motor or the means intercommunication of this shutter with other shutters take a position in a housing housed in the shutter box concerned, or even in a dwelling provided for that purpose level of masonry, in the immediate vicinity of this box.

About the engine operation management unit of a rolling shutter, it consists of everything particularly, in means allowing to manage the stopping of the motor running at the end of the opening stroke and shutter shutter closing.

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

Such electromechanical systems require adjustments meticulous and are, in fact, inoperable during use shutter. But if stopping the operation of an engine shutter occurs too late in relation to the arrival at the end of the top run of the apron, that can all just lead to the breaking of this apron. Conversely, if, when the shutter closes, the engine stops too early, it is possible that the automatic locking device shutter apron has had time to be activated.

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

Other opening limit management devices and closure of a shutter are based on the principle of of the load of the drive motor as described, by for example, in DE 39 33 266 which represents the state of the art corresponding to the preamble of appended claim 1. In short, it is about keep under control some of the parameters of the power supply of the motor to control if, through these parameters, it is deduced that this load comes to exceed predefined values or if it is recorded, instantly, a variation of load important.

Here again, these electronic management means of operation of the engine and in particular of its end position in a housed housing, either directly in the box shutter, either in a housing specially fitted out in Masonry near the latter.

However, it is obvious that the failures predominantly encountered in the operation of shutters result of a malfunction of these management means in the end motor stroke. Also, the staff providing the service is brought, systematically, to dismantle the casing of the shutter in order to access the failing parts. We will note, Moreover, in most cases, the fact of being able to access to the shutter box is not enough and it is necessary to dismantle the entire drive mechanism, extract the motor winding tube training to proceed with the repair. It is therefore a heavy and expensive intervention that can not be performed only by qualified personnel.

Finally, we will observe, again, that means of management of electronic limit switches, based on the principle of control of the motor load, are quite able to to replace a faulty electromechanical system.

In short, it would be particularly advantageous to be able to replace with such electronic end-of-stroke systems failed electromechanical management systems, all simply by making the latter inoperative.

The present invention aims to provide a solution to all the aforementioned constraints.

For this purpose, the invention relates to a device for controlling motorized roller shutter comprising a housing equipped with an inverter control for raising and lowering an apron, this inverter being connectable to a power supply and likely to be wired to the motor of training housed in a housing housing the mechanism winding and unwinding said apron, said engine associated means of management of its operation and stop command at the end of the unwinding run and winding of the apron, characterized by the fact that it is integrated into the control box, accommodating the inverter of raising and lowering control, an electronic system of end-of-travel management of the drive motor, in particular in the form of a measurement of the load of this engine, this system being connectable, wired, to the latter.

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

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

Moreover, if the substitution by a management system of electronic limit switch of an electromechanical system or mechanical failure was, until now, not envisaged in the extent that it required the integration into the box of a additional housing or the development of such a housing at the level of masonry, the present invention provides, finally, a solution to this problem. We will observe, in this regard, such a limit management system, housed in the control box, is able to intervene in replacement to any type of system previously implanted in the box, therefore, not only mechanical or electromechanical, but also electronic.

In short, through the present invention it is possible to propose to a user a definitive solution to the difficulties repetitive that he may have encountered, in the past, with a system electromechanical limit switch management.

Moreover, assuming that in a control device group of several roller shutters, these are connected current and that one of them, called a master, integrates a carrier current transmitter allowing, through it, order the opening and closing of other shutters which, they, are then provided with a carrier current receiver, said carrier current transmitter and / or carrier current receiver is, again, integrated, according to the invention, into the housing of command hosting the rising and falling control inverter lowering of roller blind apron.

In fact, such remote control means by current carrying several roller shutters are likely to generate failures in the operation of these components wheels, so that by making their accessibility easier easier repair interventions.

A design according to the invention makes it possible, moreover, to respond to a problem of equipment, a posteriori, a dwelling of a group order of its shutters. Indeed, since in an installation of the wired type, the control box, welcoming the up and down command reverser, shutters are usually connected to the network supply of electrical energy to a dwelling, it is very easy to connect to this network a receiver or a current carrier transmitter that one comes precisely to house in this case.

Finally, and as is apparent from the explanations preceding, the present invention stems from an approach inventive way through which we have been able to challenge 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 of the accompanying 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 shutter 2 comprises an engine 3, very often of tubular form, defined as suitable for the rotation of a winding tube 4 and control, according to the case, the winding or the unfolding of the apron 5 of this component rolling 2.

In this regard, the user disposes, in an accessible manner and near this shutter 2, a control box 6. It contains an inverter 7 of rising control and downstream of said apron 4, this inverter being connected to a power supply 8 and connected, so wired 9, the drive motor 3. The latter and, so general, the whole winding mechanism and unfolding of the apron 5, takes position in a box 10 overcoming the opening corresponding to a door, window or analogue equipped with said shutter 2.

According to the invention, it is still integrated in the control box 6 an electronic system 11 end of travel management of the 3. In particular, such a system is 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 of this charge over a predefined period.

Thus, this determination of the load of an engine can, by 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 engine 3.

In fact, insofar as the control box 6 comprises, in all cases, a wired link 9 connecting it to said engine 3, housed in the casing 10, it is easy to provide, at this wired link 9, the cables of necessary connections for the operation of this system of end-of-travel electronic management 11. Also, it appears obvious way that such a system 11 does not complicate more the editing and pause operations of a shutter equipped with a device 1 according to the invention.

Moreover, if a roller shutter is equipped, originally, with a mechanical and / or electromagnetic management system and / or electronic 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 by an electronic management system 11 of these purposes of races that one comes precisely to lodge in said housing 6.

In a more advanced embodiment and for the management of a group order of several shutters, it is still integrated in this control box 6 of a shutter 2, a receiver 12 and / or a carrier current transmitter 13 through the control box 6 corresponding to a component 2, configured as a master, to transmit, on the power supply network 8 to which it is connected, a signal capable of being interpreted as a command grouped by the receiver 12 integrated to the control box 6A, 6B, 6C shutters 2A, 2B, 2C qualified as slaves. A such signal may, then, lead, as the case may be, to the order opening or closing of these shutters.

Of course, this type of powerline communication allows to consider the order, since a rolling shutter master 2, the whole group 2, 2A, 2B, 2C shutters of a house or of subgroups.

Moreover, in a control box 6, 6A, 6B, 6C, can be housed a receiver-transmitter current carrying so that each shutter 2, 2A, 2B, 2C can act, according to the case, as a masterpiece or be able to retransmit, to such a roller shutter master 2, a information relating to the proper execution of a transmitted order since that last. Visual signaling means and / or sound equipping this rolling shutter master 2 can, well, retranslate, in an interpretable way by the user, this information from slave shutters.

It is obvious that by grouping at the level of the box of command 6, also integrating the control inverter 7 of ascent and descent of an apron 5 of shutter 2, all the components that could constitute sources failure of such a shutter 2, it makes easier after-sales service interventions.

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

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