Description

The present invention relates to a method for managing the combined movement of two leaves or leaves, more particularly in the event that one of the leaves encounters an unforeseen obstacle, implying a specific response from the system. In this case, in fact, the normally automated movement of the leaves is stopped and the normal closing or opening cycle can no longer continue normally.

In the absence of a problem of this order, the management of the relative displacement of two leaves respectively covering and covered with swing shutters or motorized doors is done in practice in particular by managing a time difference or a difference in speed in their movements, which requires control of the means of training and the leaves. In short, the leaves are designed to be movable between two extreme stable opening and closing positions with a view to clearing and shutting openings made in the walls of buildings. This requires prior designation of a covering leaf and a covered leaf whose combined movements are managed to prevent collisions and guarantee the complete closure of the bay if it is desired. To be able to ensure their coordinated automated movements, in particular between these extreme positions, these leaves are connected to drive means which are themselves controlled by electronic control means.

There are multiple technical solutions for the implementation and control of these training means, knowing that the problems to be solved in this context are themselves of several kinds: as mentioned, you must first be able to steer coordinated the covered leaf and the covering leaf, so that they do not collide during their movements. The resulting difference in treatment involves checking the relative positioning of the two leaves at all times in order to allow their automated movement without path interference. In many cases, the operation of these leaves also requires generating a positioning of the leaves in an intermediate position, considered optimal by the user, in particular to promote better sun protection and / or better ventilation, and that must be taken into account in management. Without forgetting the management of abnormal operating conditions which risk damaging it, such as the occurrence of high winds, or the existence of unforeseen obstacle (s) on the path of at least one leaf, conditions that it is necessary to detect and to treat and which constitute the object of the invention.

For the record, the existing technical solutions enabling these problems to be answered are varied, giving rise to sometimes very different operating modes. Thus, the majority of existing systems are equipped with a single motor which manages the simultaneous movements of the two leaves. The drive by a single motor means leads to a positioning of one of the leaves which is necessarily and at all times in the mechanical dependence of the other, implying a certain operating rigidity. The choice of a single motor in fact implies the installation of a dedicated linkage-type mechanism, for example based on a rack, which moreover occupies a non-negligible space under the central part of the lintel of the opening and mask part of its surface.

A technical alternative consists in favoring a separate motorization of the leaves, allowing independent movement, and consequently greater flexibility, the consequence of the doubling of the training equipment being in certain cases being to provide and manage communications between the two. In practice, these solutions with independent drive tracks shift the type of solution from a technically mechanical field to a more electrical / electronic approach.

Within these electronic solutions, there are responses to two electronic control units, one per motorization system, and alternatives comprising only one electronic card managing the two motorization blocks. The link between the electronic units or between the motorization systems can then be wireless or, on the contrary, wired, depending on the options chosen and the conditions of use sought.

The connections and, in certain cases, the communication between the electronic cards for managing the leaf drive means, can complicate and ultimately weaken the robustness of the solution. This is a sensitive question, particularly from the perspective of managing events such as the meeting of obstacles hindering the normal movement of the leaves, potentially destructive of the system if they are not treated, a question which is at the heart of the present invention .

The latter, which is part of the group of solutions based on drive means specific to each leaf, offers a reliable, robust and precise global solution to the problem of combined control of leaf movements, including the treatment of unforeseen events likely to upset normal system operation.

In fact, the invention is embodied more particularly in a method of managing the meeting of unforeseen obstacles during the combined movement of two leaves respectively main defined as covered and secondary defined as covering, each controlled by drive means respectively masters for the covered leaf and auxiliaries for the covering leaf, said drive means being controlled by an electronic processing unit equipping the master drive means and to which the auxiliary drive means are connected, the electronic processing unit being provided with means for measuring the displacement of the master drive means. This process is characterized in particular by the following stages: permanent detection of an obstacle which stops the movement of one of the two leaves;

if the movement of the leaves goes in the direction of opening respectively closing, no stopping of the control of the opening respectively of the complete closing of the leaf not stopped;

detection of the arrival in abutment of said leaf;

sending by the electronic processing unit to the master and auxiliary drive means of a closing signal respectively of complete opening of the two leaves; and control by the electronic processing unit to the master and auxiliary drive means of the initiation of a normal opening cycle respectively closing.

In essence, when one leaf encounters a problem during its movement, the system maintains the movement in progress of the other leaf. Then an inversion of the displacements makes it possible to return to the original situation, that is to say preceding the displacement during which the problem occurred. The system performs a sort of operation reset from the stored basic data, in particular the stop positions from which the movements start.

According to the method, when the normal closing cycle is engaged, if the main and secondary leaves do not find a complete closing position with their definition of leaf respectively covered and covering, the electronic processing unit triggers a resetting procedure making it possible to regain such a position.

In the context of the invention, a learning step is provided, which performs the detection and storage in the electronic processing unit of at least the stable open and closed positions of each leaf in the covered / covering function which their has been affected. It is notably on the basis of these memorized positions that the registration procedure is carried out.

Preferably, this learning step comprises memorizing, at least for the master drive means of the covered leaf, of the stroke traveled during the movement between the stable open and closed positions.

The system's knowledge of the stop positions or even the strokes to be carried out by the leaves allows, in the event of untimely obstacles to be detected, to reset the system at the end of the reversal of the movements and, if said reset does not correspond to the information of positioning at the terminals as memorized, triggering of a readjustment procedure.

The normal movements of the leaves are managed on the basis of a predetermined time difference and stored in a storage memory of the electronic processing unit, which is implemented when the drive means are started, upon reception of a signal. closing and opening leaves respectively in the electronic processing unit of the system.

Preferably, under the invention, the drive means are electric motors. In this case, a current threshold value reflecting the blocking of the electric motors is memorized in a storage memory of the electronic processing unit, and the instantaneous value of the current is continuously measured by means of measuring the current in each motor. electric. This value is continuously compared with the memorized threshold value, and each electric motor is stopped when the instantaneous value measured there is

The invention also relates to a device for managing the combined movement of two leaves, respectively covering and covered with swinging shutters or motorized doors, movable between two stable open and closed positions for the release and closing of door openings or windows, each of the leaves being equipped with drive means managed according to the method mentioned above in the event of an obstacle meeting, and which is in particular such as the means

auxiliary drive means of a second leaf, said master and auxiliary drive being connected to an electronic processing unit equipping the master drive means.

There is therefore, in the hypothesis of the invention, only one electronic card which reports to the master drive means, and which manages the two drive devices.

This electronic processing unit comprises a receiver of radiofrequency signals, at least one data storage memory and means for measuring the displacement of the master drive means. The purpose of the receiver is in particular to receive, with a view to processing them, the signals sent by a remote control capable of actuating the flaps, leaves, leaves ...

Preferably, the drive means consist of an electric motor for each leaf, and the measurement means consist of a tachometer which measures the displacement of the master motor, that of the auxiliary motor can be deduced from the knowledge of the delay and measurement of the currents signaling the arrivals at the stop.

The counting of the revolutions traversed by the motor shaft is a simple operation to perform, very reliable, and which makes it possible to give an extremely precise indication of the position of the leaf. It is also a simple and effective way to manage intermediate positions if necessary, for example a predetermined half-open position of the leaves, or to help in the evaluation of situations which deviate from the basic functioning of closing and to open the leaves.

According to a preferred possibility, the drive means can be powered by at least one battery recharged by at least one photovoltaic panel, which makes the operation of the leaves energetically autonomous.

As mentioned, the system is controlled by means of a radio frequency transmitter remote control sending opening and closing messages to the receiver of the electronic door leaf processing unit. It is in fact the interface, for the user, allowing him to operate the assembly.

In order to implement the offset displacements of the leaves and to detect in particular the arrivals at the stop, the electronic processing unit comprises a delay stage and means for measuring the current in the motors. They allow in practice to detect an engine blocking, since this causes

The invention will now be described in more detail, with reference to the appended figures, for which:

- Figure 1 shows a simplified flowchart of system operation when a leaf meets an unforeseen obstacle to 1'opening; and

- Figure 2 shows a similar flowchart of system operation when a leaf meets an unforeseen obstacle to closing.

With reference to FIG. 1, when an operator actuates a remote control for the opening of shutters or leaves capable of closing a bay, said remote control sends a radio frequency signal received by the receiver of the electronic processing unit which controls the two motors. The control of the leaves is done as we have seen with a slight shift of

one with respect to the other to avoid any positional interference in the opening strokes of the two leaves. More precisely, during an opening phase, the covering leaf starts to move a few seconds before the covered leaf, in other words the auxiliary motor is actuated first, followed with a slight offset from the master motor.

If one of the leaves, whatever it is (covering or covered) encounters an unforeseen obstacle, detected in the system by an increase in the torque and therefore of the current, said leaf is blocked, and the supply of the corresponding motor is cut off. by the electronic unit. However, this maintains control of the opening of the other leaf until it reaches the stop in its fully open position.

When this arrival at the stop is detected, the electronic processing unit controls the closing of the two leaves, which is in principle possible since the obstacle encountered is located in the path of the opening and is therefore not active in a closing movement.

When the two leaves are correctly closed, the system then commands a new normal opening cycle. In the event that the main leaf carrying the master motor does not find, at the end of this closing operation, in its initial closing position as resulting in particular from information stored via the rev counter, leading to a closing which is not correctly performed, a readjustment procedure is launched, which guarantees that the covered leaf is completely covered by the covering leaf.

The equivalent is true during an operating cycle aimed at closing the leaves, as shown in the figure

2. We start from an open position and a normal closing cycle is initiated by action on the remote control, then echoed by the electronic processing unit which controls the two motors: first the master motor of the covered leaf and then, after a delay of a few seconds, the auxiliary motor of the covering leaf.

If an obstacle occurs on the closing path of at least one of the two leaves, the system suspends the control of the corresponding motor but does not act on the motor control of the other leaf, which closes normally. When it arrives at the stop, the electronic unit controls the opening of the two leaves, which is a priori possible since the obstacle encountered opposes the closing and not the opening of the leaf concerned. Then, the system initiates a new normal closing cycle.

The management of unforeseen obstacles type events opposing the movements of the leaves is carried out, within the framework of the invention, by a simple and effective process implemented by a particularly robust and reliable device.

The invention is of course not limited to the operating examples which are set out with reference to the figures, but it encompasses the variants and versions which fall within the scope of the claims.
