EP2495386A1 - Operating method of a mobile screen with adjustable slats of a building - Google Patents

Abstract

The method involves carrying out orientation of opening or closing of two or three adjacent orientable slats (3') one after the other during execution of orientation control, in an orientation mode i.e. gradual orientation mode. The orientation of opening or closing of the two or three adjacent orientable slats is carried out simultaneously during execution of the control in another orientation mode i.e. fully extended/retracted orientation mode. The gradual orientation mode or the fully extended/retracted orientation mode is determined based on a position of a shutter during the execution. An independent claim is also included for an orientable slat integrated movable screen for a building.

Description

The invention relates to a method for operating a moving screen with motorized steerable blades by means of an electromechanical actuator in a building and in particular an operating method related to the orientation of the blades of the mobile screen. The invention also relates to such a motorized mobile screen.

An electromechanical actuator allows the motorized control of occultation or sun protection elements placed at openings in a building. In particular, it allows to control a mobile screen comprising steerable blades, such as a rolling shutter with adjustable blades, a venetian blind indoor or outdoor, or adjustable panels. It also relates to a method of operating such a device

Various devices are known blades steerable, whose movement is controlled by electromechanical actuators. These installations generally comprise a mechanical rocker cooperating with a pin at the end of one of the blades of the deck. When the pin is moved in the rocker, as a result of an overall movement of the deck, the set of blades can be inclined relative to the main plane in which the deck moves. The movement of the pin in the rocker corresponds to a tilting angle of the blades. Such a rocker is described in the patent FR2573551 .

In a similar way, so-called shutters with perforated blades allow to obtain a spacing of the blades located at the bottom of the deck to allow aeration and clear day. However, they do not allow not to release an interesting field of vision and likely to satisfy a user.

Documents are known DE10120998 and EP1149977 a slatted awning device in which two sets of slats are mounted on independent ladders. Thus, it is possible to order different blade orientations for both sets of blades.

The object of the invention is to provide an operating method which overcomes the disadvantages mentioned and improves the methods known from the prior art. In particular, the invention therefore proposes to solve the problems cited related to the prior art and to provide an operating method including the orientation of the blades, which is both intuitive and simple. In particular, the invention provides a control device of an apron that provides both safety when closed and offers a plurality of comfort solutions to users.

According to the invention, the method governs the operation of a movable screen with steerable blades of a building, the screen being motorized using an electromechanical actuator, a set of blades forming an apron that can be moved between two extreme positions and at least some of the blades can be oriented relative to the plane of the deck, on receiving commands respectively moving and orientation of the blades. The method comprises a first and a second distinct orientation mode in which the opening or closing orientation sequence of two adjacent steerable blades, or even three adjacent steerable blades, is different, or even in which the orientation sequences opening or closing of the blades of two pairs of adjacent steerable blades are different.

The orientation sequence of the two adjacent steerable blades, or even three adjacent steerable blades, can be performed differently for the same orientation control performed in the first and second modes.

The first orientation mode may be a gradual orientation mode, in which the two adjacent steerable blades, or even three adjacent steerable blades, are oriented one after the other during the execution of the control of orientation.

The blades can be oriented one after the other from the blade closest to a winding tube of the apron of the screen.

A control command corresponding to an intermediate position can cause a change of a predefined number of blades.

The second orientation mode may be an all-or-nothing orientation mode, in which the two adjacent steerable blades, or even three adjacent steerable blades, are oriented simultaneously during the execution of the orientation control.

The orientation mode can be determined according to the position of the apron at the time of the execution of the orientation command.

The total travel of the deck can be subdivided into several zones, a first zone corresponding to the first mode of orientation of the blades, a second zone corresponding to the second mode of orientation of the blades.

The orientation mode can be determined by a particular command associated with each of the orientation modes and distinct from an open and close command.

The blades can be oriented before a movement of the deck towards one of the two extreme positions, in particular towards the winding position.

The oriented blades can be kept oriented during at least part of the movement of the apron to the end position, in particular to the winding position.

The blades can be tilted to their unoriented position before moving the apron to the other extreme position, in particular to the unwinding position.

According to the invention, the mobile screen with steerable blades of a building is motorized with the aid of an electromechanical actuator, a set of blades forming an apron that can be moved between two extreme positions and at least some of the blades that can be oriented relative to the plane of the deck, on receipt of commands respectively displacement and orientation of the blades. The screen comprises hardware and / or software means for implementing the steps of the method defined above.

The material and / or software means may comprise means for defining the opening or closing orientation sequence of two adjacent steerable blades, or even three adjacent steerable blades, differently in a first and a second orientation mode, even definition of orientation sequences, opening or closing of the blades of two pairs of steerable blades adjacent differently in the first and second orientation modes and means for determining the activation of the first orientation mode or the second orientation mode.

The material means may comprise first and second distinct zones of position of the final blade, the blades being dependent on a means of orientation of the blades in the first zone and independent thereof in the second zone.

The invention also relates to a data storage medium readable by a computer on which is recorded a computer program comprising computer program code means for implementing the phases and / or steps of the method defined above.

The invention further relates to a computer program comprising computer program code means adapted to perform the steps of the method defined above, when the program runs on a computer or computer.

The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings in which:

• The figure 1 represents a diagram of a first embodiment of a screen according to the invention.
• The figure 2 is a flow chart of a first operating procedure of a screen according to the invention.

• The figure 4 represents two diagrams of a screen according to the invention, in two different configurations.

The figure 1 shows schematically an embodiment of a motorized mobile screen or motorized screen device 100 according to the invention. The motorized screen device with adjustable blades, for example a rolling shutter with steerable blades, comprises a set of blades forming an apron 4, some 3 are fixed and others 3 'are rotatable. The screen is driven in motion by an actuator 10, in particular an electromechanical actuator, disposed in a winding tube (and shown for the legibility of the figure outside thereof) around which the apron is wound when the screen opens. It moves between two lateral guides for guiding the blades. These slides are capable of allowing the translation and rotation of the different blades.

The apron may include a certain amount of fixed blades (non-steerable) between the winding tube and the upper tilting blade. Similarly at the bottom of the deck, a certain amount of fixed blades can be arranged at the bottom of the lower tilting blade. Only some central blades are then tilting, without this changing the operating method compared to an apron with all blades would be tilting or steerable.

The device also comprises a rocker shown schematically by the reference 7, in particular a friction rocker, allowing the orientation of at least some blades.

The actuator comprises an electromechanical portion 11 (motor, gear, brake), connected to an electronic control unit 12. The control unit controls the operations of the electromechanical part of the actuator by an information transfer (in the form of electrical communication mainly) symbolized by a double arrow 13. The apron is driven under the action of the actuator, between extreme positions FDCH and FDCB, in the same way as for a conventional roller shutter without adjustable blades. In particular, the final deck blade, furthest from the winding tube, moves between these two positions.

The actuator may comprise various sensors, such as for example a torque sensor 16, a position sensor 17. It also comprises a command receiver 18 (in the case of a bidirectional communication actuator, the command receiver is therefore a transceiver) provided with an antenna 19 and hardware and / or software means for governing its operation in accordance with the operating method of the invention.

The device is associated with a control point 20 connected by a wired or wireless communication network 40. The control point comprises, for example, a first set 20a of two keys 21 and 22, enabling the transmission of a control command for moving the screen, that is to say opening or closing the screen. screen. The control point comprises for this purpose an order transmitter 28 provided with an antenna 29, the command transmitter being able to communicate with the command receiver of the actuator. When this order is received by the receiver of the actuator, it is translated into a mechanical action making the opening or closing of the screen by winding the blades at a high position close to the box or by deployment of the blades to a low position. A central element 20b for example in the form of a wheel makes it possible to control an orientation of the blades in a first direction or in a second direction.

The different commands can also be transmitted by means of a remote control comprising three buttons (Climb, Descent, Stop), different types of support on the different keys giving rise to different orders, including orders of orientation.

In these cases, the orientation commands can be issued from the motion control keys. Particular ergonomics of support on these keys (for example long supports, of a duration greater than 0.5s for example for displacements - short supports, lasting less than 0.5s for orientations) then makes it possible to distinguish the commands of displacement of the commands of orientation.

A light-emitting diode 24 (or any other graphical interface element, for example a screen) makes it possible to display information at the control point.

The orders or commands transmitted by the control point, either directly to the order receiver, or through a not shown control box include an order type indication (opening, closing, orientation direction 1 or direction 2, intermediate positioning, etc.) which qualifies the mechanical movement to give to the mobile screen.

According to the invention, the device can operate in one of three modes: a mode of displacement and two distinct modes of orientation.

A first mode of orientation is said mode of gradual orientation of the blades. "Gradual orientation of the blades" means the successive orientation of one blade after the other during a printed motion to the winding tube. The blades are oriented without moving the final blade of the screen. The orientation sequence of two blades adjacent, or three adjacent blades, is defined by a successive movement of each of the two blades, or each of the three blades. The gradual orientation can for example be obtained through the use of the friction rocker, whose operation is described below.

If we consider three adjacent blades (an upper blade, an intermediate blade, a lower blade), the orientation sequence of these three adjacent blades involves, in the first mode, different orientation positions of the upper blade, the blade intermediate and the lower blade at a given time during the opening or closing movement of the screen.

If two pairs of adjacent blades are considered, in the first mode, each of the blades of a first pair of blades undergoes a successive sequence of orientation of the blades during the opening or closing movement of the screen. In the first mode, each blade of a second pair of blades is also subjected to a successive sequence of orientation of the blades during opening or closing.

A second mode of orientation is said mode of orientation all-or-nothing. In this orientation mode, the blades are all oriented simultaneously; they move from the closed or unoriented position to an open position, the angle of inclination is identical for all blades. The orientation sequence of two adjacent blades, or even three adjacent blades, is defined by a simultaneous movement of the two blades, or each of the three blades. The open or inclined open or oriented position of the blades is preferably such that the blades are oriented at an angle of about 45 ° with respect to the plane of the deck. The closed or non-oriented position of the blades is preferably such that the blades are oriented at least substantially parallel to the plane of the deck.

Still considering the three adjacent blades (an upper blade, an intermediate blade, a lower blade), in the second mode, the orientation sequence of these three adjacent blades involves, in the second mode, equivalent orientation positions of the upper blade, the intermediate blade and the lower blade at a given time during the opening or closing movement of the screen.

If two pairs of adjacent blades are considered, each of the blades of the first pair of blades undergoes a simultaneous sequence of orientation of the blades of the opening or closing movement of the flap in the second mode. Still considering these pairs of adjacent blades, in the second mode, each of the blades of the second pair of blades also undergoes a simultaneous sequence of orientation of the blades during opening or closing.

Thus, the opening or closing orientation sequences of the blades of each of the two pairs of steerable blades, in particular of each of the two pairs of adjacent steerable blades, are each different in the first and second modes. The orientation of a blade of one pair relative to the other blade of this pair is thus specific to the orientation mode.

A first orientation sequence of opening or closing of the blades of the first pair of adjacent steerable blades, performed in the first orientation mode (for example a successive orientation sequence), is different from this first orientation sequence. opening or closing the blades of the first pair of adjacent steerable blades, executed in the second mode a second orientation sequence of opening or closing of the blades of the second pair of adjacent steerable blades, executed in the first orientation mode (for example a sequential sequence orientation), is different from this second orientation sequence of opening or closing of the blades of the second pair of adjacent steerable blades, performed in the second orientation mode (for example a simultaneous sequence). The first and second couples may be adjacent.

The mobile screen with adjustable blades comprises hardware means and / or software means for controlling its operation in accordance with the method of the invention, in particular to govern the steps of this method and their sequences. The material means comprise the electronic control unit. The software means may be contained in the electronic control unit. The software means may in particular comprise a computer program code means adapted to performing the steps of the method according to the invention, when the program runs on a computer. The software means include:

• means for defining the opening or closing orientation sequence of two adjacent steerable blades, or even three adjacent steerable blades, differently in a first and a second orientation mode, or even for defining orientation sequences of opening or closing the blades of each of two pairs of adjacent steerable blades differently in the first and second orientation modes, and
• means for determining the activation of the first orientation mode or the second orientation mode.

These two means are for example modules of the electronic control unit.

The mode of displacement is described in relation to the flowcharts of figures 2 and 3 .

In particular, as shown in figure 2 , an opening command issued during a step S1 through the control point and received during a step S2 by the device, while the final blade of the screen is in the end position low FDCB, has for object the rise of the apron, and in particular, the rise of the final blade of the apron. The opening command initially causes the gradual orientation of the blades not oriented at the time of issue of this command. Step S3 makes it possible to symbolize the alternatives: the blades are all or partly inclined, or none of the blades are inclined at the time of receipt of the opening command. If the blades are not all in the open inclined position in step S3, the control first causes a gradual orientation of the closed blades to an open inclined position in step S4, before the final deck blade is driven up during step S7. If all the blades are already oriented in an open inclined position, the blades are held in this open inclined position (step S5) and the final deck blade is driven upward in step S7.

Due to the systematic opening of all the tilting blades when executing an opening command, the user has an optimal field of vision as soon as possible. It is therefore not necessary to wait for the complete rise of the apron to have an outward vision. The blades close automatically and successively during the winding of the apron around the winding tube and the successive thicknesses of the deck, during a step S7. It should be noted that a means is provided for bringing the blades back to their non-oriented position so that they can be wound on the winding tube, for example by cooperation of the blades with the winding tube or the blades wound thereon, or by contact with a dedicated accessory.

In the equivalent way, as shown in figure 3 , a closing command issued during a step S11 through the control point and received during a step S12 by the device, causes the unwinding of the deck. If the closing command is received while the apron is in a partial unwinding position, it is possible that some or all of the blades are inclined. This situation is symbolized by the step S13. If the blades are already all closed, the progress of the deck causes the movement of the final deck blade to the extreme low position FDCB, the blades being kept closed (step S14). In the case where some blades are inclined, in response to the closing command, the unfolding of the apron then causes in the first place the closure of the blades which were possibly inclined, during step S15, before the final blade is moved to the extreme low position.

In this way, the closing movement has an immediate effect, composed successively of the closing of the remaining blades inclined and the lowering of the deck. Again, these provisions are quite logical vis-à-vis a closure command and correspond to the expectations of the user.

They also ensure a safe closure of the deck in extreme low position. The apron is indeed driven with the blades closed to this position. When the apron is in this closed position, the blades are oriented only upon receipt of an opening command. There is no risk of unexpected opening of the blades at during the execution of this closing command, even if the device is not adjusted.

Orientation modes are represented in relation to the figure 4 .

The total stroke of the screen is divided into several areas. In particular, a first zone TILT1 called gradual zone, is located at the bottom of the race. When the screen is in this area (specifically, when the final blade of the screen is in this position area), executing an orientation command will result in a gradual orientation of the blades. A second TILT2 zone is located in the middle of the race. When the screen is in this area (specifically, when the final blade of the screen is in this position zone), the execution of an orientation command will result in a total and simultaneous orientation of the blades. Beyond this TILT2 zone, the blades may or may not be oriented, but because of the winding of the deck, this orientation concerns at most only some of the blades.

The two orientation modes therefore correspond to orientations of the controlled blades while the final blade is in one or the other of the two distinct zones defined above TILT1 and TILT2. A particular command, received by the receiver of the device, may combine a movement control to one of the zones of the race and a blade orientation command in this zone.

Alternatively or in a complementary manner, the two orientation modes depend on the use of a first or second blade tilting device. The first tilting device allows for example to obtain a behavior of the blades according to the first orientation mode. The second switching device makes it possible, for example, to obtain a behavior of the blades in accordance with the second orientation mode. For example, either of the first and second tilting devices is selectively enabled depending on whether the screen is in the first orientation mode or the screen is in the second orientation mode. Means is preferably provided for determining the active orientation mode.

A tilting device may comprise cams associated with the steerable blades and cooperating with a friction band in the guide rails of the blades, the frictional forces of the strip on the cams causing the pivoting thereof and, consequently, the orientation of the associated blades. Such a device makes it possible to control the simultaneous orientation, in a first direction of rotation, of several blades when the blades are driven in a first direction of displacement and the successive orientation, in a second direction of rotation, of several blades when the blades are driven in a second direction of movement, this successive orientation of the blades occurring when they reach a particular point of the stroke of the deck.

The first and second tilting devices constitute means for defining the orientation sequence of two adjacent steerable blades, or even three adjacent steerable blades, differently in a first and a second orientation mode, or even for defining the sequences of orientation of opening or closing of the blades of two pairs of orientable blades adjacent differently in the first and second orientation modes.

Alternatively, the two orientation modes are selected by selecting an operating mode, the selection having a mechanical impact on the blade orientation device. For example, a zipper mechanical takes a first or second position according to the selected orientation mode, which allows to tilt differently two adjacent or contiguous blades, or three adjacent or contiguous orientable blades. In particular, the opening or closing orientation sequence of the two adjacent steerable blades, or even three adjacent steerable blades, is different in the different modes. In one mode, the upper blade can be oriented in opening before the lower blade. In the case of three blades, the upper blade can be oriented in opening before the intermediate blade, itself being oriented in opening before the lower blade. In another mode, the lower blade can be oriented in opening before the upper blade. In the case of three blades, the lower blade can be oriented in opening before the intermediate blade, itself being oriented in opening before the upper blade. In yet another mode, the lower, upper and optionally intermediate blades can be oriented in opening simultaneously. In this context, the two orientation modes can be two modes of gradual orientation, one corresponding to an orientation of the blades from bottom to top and the other corresponding to an orientation of the blades from top to bottom. The user can thus choose the orientation that suits him best at a given moment and modify it as he wishes.

Preferably, these different sequences are triggered by the same control command, such as a command to close the screen or an order to open the screen. In particular, these different sequences can be triggered by the same action of the user, it is then the state or mode of operation of the screen or the orientation mode of the blades that determines the sequence that is executed.

Two preferred modes of orientation are described later.

First orientation mode

Preferably, the gradual orientation from a closed deck position is made from the tilting blade closest to the winding tube. In the case where the upper tilting blade is the first blade to tilt in opening, the gradual inclination of the blades during an opening movement will allow in the first place a through view to the top of the deck, and this even though the blades at the bottom of the deck are still in the unoriented position.

It is then possible to create a space with an open field of view Z01, Z02 towards the outside towards the top or the middle of the deck, more or less large, while keeping a closure of this apron (closing seal in extreme low position ). This allows the light to enter the room equipped with the mobile screen, while restricting entry or exit to young children or pets for example even though the window can be kept open. The intimacy in the room is also preserved by keeping the bottom of the apron ZF1, ZF2 in the closed position.

Alternatively, all the blades can be tilted so that the lighting in the room is maximum while keeping the bottom of the deck in the closed position, and thus maintaining a closed access.

A gradual intermediate position P11, corresponding to a predetermined number of oriented blades, may be prerecorded. It then suffices, by a particular control ergonomics, to issue a corresponding control command, so that the screen comes to be positioned at the required screen position, with the desired number of oriented blades. It is not necessary to position the final blade of the screen manually in the first TILT1 orientation area for reach this intermediate position. Ideally, the required movement is made automatically, from any starting position, in which the device receives the particular control command to go to the intermediate position.

For example, if the particular command is received while the apron is closed, the execution of the order consists of a gradual orientation of the blades until the predetermined number of blades is oriented.

If, on the other hand, the particular command is received while the apron is open, the execution of the order consists of a movement of the deck to its closed position, then a gradual orientation of the blades until the number of predetermined blades is oriented.

Advantageously, this intermediate position may also be an intermediate position of ventilation, in which a portion of the blades is inclined, for example the first quarter of the blades, those located at the top of the deck. This intermediate ventilation position allows air circulation up the opening, which is all the more suitable for use with tilting windows. This intermediate ventilation position is also used for illuminating the room.

Unlike perforated shutters in particular, this intermediate ventilation position is safer, insofar as the blades located towards the bottom of the deck remain unoriented and contiguous.

Advantageously, several gradual intermediate positions can be predefined on this zone.

Two intermediate positions having Z01 and Z02 viewing areas are shown in FIG. figure 4 . The final blades of the decks rest on the ground, while the number of inclined blades differs.

Second orientation mode

When an orientation command is carried out while the apron is in a second so-called "all-or-nothing" zone (precisely, when the final blade of the screen is in this position zone), in other words when the apron is outside the first gradual zone, the blades orient themselves simultaneously.

Insofar as the apron is partially wound, all the blades can not necessarily be oriented in particular, those included in the apron part already wound around the winding tube.

This second orientation mode makes it possible to obtain a fast and immediate orientation of the tilting blades, in cases where the user does not particularly look for a privacy situation. On the contrary, this second orientation mode makes it possible to use the screen in the manner of a venetian blind, the screen being partially open and the blades being able to be oriented at will.

For simplicity, especially to avoid the presence of another rocker system, the blades are automatically oriented to their maximum and the orientation angle is not adjustable in this second orientation mode.

An intermediate position PI2 set can also be recorded. In this case, it corresponds to an opening percentage shutter, the set of blades on the deployed part of the deck being oriented.

A third intermediate position could also be recorded for the travel mode. It would then correspond to a percentage of opening of the apron, closed blades (not oriented).

During the installation of the device, the height of the deck can be determined once the extreme positions (FDCH, FDCB) defined. From this apron height can be deduced the number of steerable blades (whose height is substantially standard) and the number of angular increments necessary for the orientation of an additional blade in case of gradual orientation. These calculations make it possible in particular to define which motor increment (or orientation angle of the winding tube) must be made for the orientation of an additional blade. In the case of a command by wheel, each increment wheel may correspond to an engine increment or a subdivision of this engine increment. In the case of a control point with keys, each brief press may correspond to an engine increment or a subdivision of this engine increment.

The intermediate position (s) can also be predefined from the measured and / or calculated values. These intermediate positions can then be replaced by intermediate positions recorded by the user and corresponding to a percentage of blades inclined relative to the total of tilting blades.
