Description

The invention relates to the field of control devices of a closure device of a building comprising a movable panel type sliding or tilting type. In the first case, the movable panel is vertical and able to move on a horizontal rail relative to a fixed frame on a bay in a building. In the second case, the movable panel switches around a horizontal axis. Moving the movable panel is motorized.

The invention aims to solve problems of driving and locking the movable panel as well as that of the ventilation of a closed room by the movable panel.

The invention applies in particular to sliding windows, but also to sliding shutters, sliding doors or patio doors, glazed or solid, comprising at least one movable vertical panel, guided by a horizontal rail, possibly capable of lead to other moving panels. The invention also applies to flap type windows or ventilation hatches.

US Pat. No. 5,226,256 discloses a tilting type mobile panel window that can be used to allow automatic ventilation of a room. These documents do not provide ventilation means for natural ventilation of the closed room by the mobile panel, when the mobile panel is closed and locked.

An important problem with the use of a sliding or tilting panel as a means of ventilation is that a ventilation position is achieved by partially opening the panel, providing a ventilation space between the movable panel and the frame. The movable panel is then weakened by the possibility of introducing a tool into the ventilation space and to force the opening thereof.

The object of the invention is to provide a control device overcoming the above drawbacks and improving the known devices of the prior art. In particular, the invention provides a device for controlling a simple closure device for ventilation while a movable panel is closed and locked.

According to the invention, the device makes it possible to control a closure device of a building, the closure device comprising a movable panel and a ventilation means. The control device comprises a carriage movable relative to the movable panel, the carriage: - driving the movable panel when the carriage is immobilized relative to the movable panel and - controlling a change of state of the ventilation means when the carriage moves relative to the mobile panel. In a closed position of the movable panel, the carriage can be movable between a non-activated state position of the ventilation means and an activated state position of the ventilation means.

The ventilation means may comprise a first opening and a second opening, the first and second openings being in coincidence in the activated state of the ventilation means and in non-coincidence in the non-activated state of the ventilation means. At least one of the first and second openings may be closed when the carriage is in the non-activated state position and the openings may not be closed when the carriage is in the activated state position. The carriage may have an intermediate position relative to the movable panel in which the ventilation means is partially activated, at least one of the openings being partially closed. The first opening may include a plurality of holes and the second opening may include a plurality of holes. The ventilation means may comprise a seal between the first and second openings and / or between the first opening and the carriage and / or between the second opening and the carriage.

The movable carriage can control the activation and deactivation of a locking means in a closed position of the movable panel.

The locking means may be activated before a change of state of the ventilation means when the movable panel has reached the closed position.

The locking means may comprise a bolt, a locking hole, the bolt being engaged in the hole in a locking position of the movable carriage and out of the locking hole in a non-locking position of the movable carriage. The carriage can be moved by a drive comprising a flexible transmission element pushed or pulled. According to the invention, the closure device of a building comprises a movable panel and a control device defined above. According to the invention, the method governs the operation of a control device of a closure device of a building, the closure device comprising a movable panel and a ventilation means, the control device comprising a movable carriage relative to the mobile panel, the carriage driving the movable panel when the carriage is immobilized relative to the movable panel, the carriage controlling a change of state of the ventilation means when the carriage moves relative to the movable panel and the carriage being moved by a drive device. The method comprises the following steps: activating the drive device to exert a first moving action of the carriage so as to close the movable panel, and after closing the movable panel, activate the drive device to exert a second moving action of the carriage so as to activate or not the ventilation means. The second action may have the same meaning as that of the first action or may be in the opposite direction to that of the first action.

Closing the movable panel may result in activation of a locking means.

The invention will be better understood on reading the description which will follow, given solely by way of example and with reference to the appended drawings in which: FIG. 1 represents a first closure device according to the invention, sliding type, in a first state said "locked-ventilated", a carriage being in a second position.

Figure 15 shows part of the second device in a "locked-ventilated" state. Fig. 16 shows part of the second device in a "locked-sealed" state.

Figure 17 shows part of the second device in a "semi-open" state.

Figure 1 shows a front view and schematically a first closure device 100 according to the invention. The closure device is a sliding window type window and is shown in a first so-called "locked-ventilated" state, that is to say that the movable panel (s) of the closure device are locked in the closed position and that an air passage for ventilation is provided at the closure device. The invention applies equally to any closure device comprising a movable vertical panel adapted to move on a horizontal rail relative to a fixed frame on a bay in a building.

The window comprises a fixed glazing 11 and a dormant assembly of the closing device, simply designated as the use by "the frame". The frame comprises a vertical left frame 12, an intermediate vertical frame 12 * visible in FIG. 3, a vertical right frame 13, a lower horizontal frame 14 which is associated with a horizontal rail 15 fixed on a base 16, and a horizontal frame. 17. These five elements are assembled rigidly and the fixed glazing is assembled between the two horizontal frame, the left vertical frame and the vertical intermediate frame. The window also comprises a movable panel 20 provided with a glazing 21. The movable panel is able to move on the horizontal rail. The elements of the frame are for example made of extruded aluminum profile, with different shapes resulting from the mechanical stresses and thermal insulation of each element. The upper horizontal frame generally has a U-shaped section overturned, open downwards, which allows it to hide or guide the upper part of the movable panel. The closure device 100 comprises a device 10 for controlling the state of the mobile panel 20.

In Figure 1, the window is closed, that is to say that the movable panel 10 is disposed in contact, especially in close contact with the right vertical frame.

The control device comprises a locking means 30, comprising a bolt 31 for example secured to the movable panel and 15 being engaged in a first locking hole 18 for example made in the frame, in particular in the upper horizontal frame.

The control device or the window also comprises a ventilation means 40, for example a natural ventilation means, comprising a first ventilation hole 19 of the upper horizontal frame. By convention, the interior of this first ventilation hole is shown in white when it is not masked and thus let the air pass.

As will be confirmed below, the window is here closed, in a first state that is both locked and ventilated. In this state, a mechanical action external to the control device and exerted on the movable panel does not move the movable panel and an air passage allows natural ventilation at the closure device. FIG. closure device, in a second state called "locked-tight", that is to say that the movable panel of the closure device is locked in the closed position and that an air passage allowing ventilation is not arranged at the closure device. In this state, an external mechanical action on the movable panel does not move the movable panel.

The only difference with FIG. 1 is that the first ventilation hole 19 is closed, which is represented by a black filling of the hole 19.

The window is closed, locked and airtight insofar as this can only occur through the ventilation means 40.

The ventilation of a room closed by the window can be done without the slightest risk of burglary and / or without attracting the eyes of a potential wrongdoer.

FIG. 3 shows the closure device, in a third so-called "semi-open" state, corresponding to an opening of the movable panel in an intermediate position. The movable panel is no longer in contact with the right vertical frame. Likewise, the bolt no longer appears in the first locking hole 18. On the other hand, the intermediate vertical frame 12 *, which was masked on the first two figures, appears by the unglazed part of the movable panel.

Figure 4 reproduces Figure 1 in the case where three elements have become transparent, at least partially: the left vertical frame 12, the upper horizontal frame 17 and a lower portion of the sliding panel as described below. The movable panel comprises a frame enclosing the movable glazing 21 and consists of a vertical upright 22, a upright upright 23, a lower horizontal crossbar 24 and an upper horizontal cross 27. These four elements are rigidly assembled. The lower horizontal cross member 24 is shown in partial transparency. A first wheel 25 and a second wheel 26 are arranged on the lower horizontal crossbar, the latter generally having an inverted U-shaped section, and cooperate in rotation with the horizontal rail. The two rollers support the mass of the movable panel and the movable panel can thus be moved in translation by rolling rollers on the rail.

The upper horizontal cross generally has a U-shaped section, open upwards.

It comprises a second locking hole 28, also traversed by the bolt 31. It likewise comprises a second ventilation hole 29, unobstructed in this position.

The control device comprises a motorized drive device 50 comprising in particular a chain 51 circulating in the left vertical frame, a chain drive 52 with an angle gear located at the intersection of the left vertical frame and the upper horizontal frame, and a electric actuator 54 adapted to receive commands from a remote control, as represented by the symbol of an antenna. The chain is preferably free in the left vertical frame and undergoes only the tension due to its weight, while it is guided (by a guide means not shown) and under stress in the upper horizontal frame. The chain trainer comprises a gearwheel 53 engaged with the electric actuator and with the chain 51.

Upon receipt of a closing command, the electric actuator activates the rotation of the gearwheel in a direction pushing the chain towards the movable panel. Upon receipt of an opening command, the electric actuator activates rotation of the sprocket in one direction pulling the chain toward the chain drive.

A first end of the chain is located in the upper horizontal frame, and connected to a carriage 55 housed inside the upper horizontal crossbar of the movable panel. This carriage is able to move in this horizontal cross, under the effect of a force exerted by the chain. An elastic means 56, for example a helical spring guided by a housing, nevertheless opposes its movement towards the upright upright.

Thus, a thrust of the chain on the carriage causes a push of the carriage on the elastic means 56 and causes a movement of the movable panel if it is free to move.

On the other hand, if the movable panel is in contact with the right vertical frame, then a thrust of the chain on the carriage can cause only a displacement of the carriage in the movable element, this displacement being itself limited by a maximum deformation. elastic means.

A second end 51 * of the chain can be stored in a storage means 99 which may for example comprise a hollow housing. This storage means may for example be located in the left vertical frame. During a pulling movement of the chain and the carriage, this second end descends freely and, if it reaches a lower surface of the frame, is naturally stacked as represented by the reference 51 *. A large chain length can thus be stored without difficulty, which allows the motorization of a large window width.

Figure 5 partially reproduces Figure 4, so in a locked-ventilated state, in the case where a fourth element has become partially transparent. This fourth element is the upper horizontal crossbar. The carriage 55 and the elastic means 56 are then visible in almost all. The locking and ventilation holes are represented by their dotted line trace. It is found that the first locking hole 18 and the second locking hole 28 are superimposed, which allows the bolt 31 to pass through simultaneously. It is also noted that the first ventilation hole 19 and the second ventilation hole 29 are superimposed, which allows the air to pass through without difficulty. The carriage is in a second position relative to the movable panel.

Figure 6 partially reproduces Figure 2, under the conditions of transparency of Figure 5, corresponding to a locked-sealed state. The locking and ventilation holes are represented by their dotted line trace. The movable panel has not moved, however, the chain has pushed the carriage to the upright upright 23 of the movable panel, which has the effect of compressing the elastic means. In its new position, the carriage simultaneously closes the first and second ventilation holes. This state is therefore qualified as waterproof. The term "watertight" should be appreciated in relation to the state in which nothing prevents the flow of air through these two ventilation holes. This point will be specified later. The carriage is in a first position relative to the movable panel.

Figure 7 partially reproduces Figure 3, under the conditions of transparency of Figure 5, corresponding to a semi-open state. The locking and ventilation holes are represented by their dotted line trace. The movable panel was moved to the left, the chain having pulled the carriage towards the vertical left frame. The elastic means has thus taken a larger extension than in the case of FIG. 4. The bolt is this time engaged only in the second locking hole 28, but it no longer passes through the first locking hole 18. , the first ventilation hole and the second ventilation hole are now shifted. The carriage is in a third position relative to the movable panel.

The carriage could also be in a fourth position, for example between the first and second positions, in which it only partially seals the openings of the ventilation means. Thus, the ventilation means may only be partially closed off.

Diagrammatic sectional views make it possible to better describe the operation of the invention. The sections of FIGS. 8 to 10 are made in a median horizontal plane with respect to the locking holes and the ventilation holes. These figures have the same horizontal scale as the previous figures in the moving direction of the movable panel, against the horizontal scale in the direction perpendicular to this direction of travel have been multiplied by 2 so as to give better readability, despite the resulting deformation.

Figure 8 shows partially and schematically a horizontal section of the device in the locked-ventilated state. The vertical upright 22 is hollowed in its upper part to let the chain. It has an inner face 22a, movable glass side, adapted to serve as a stop to the carriage when it moves to the left. The upright upright 23 is in contact with an inner face 13a of the right vertical frame. The carriage comprises two parallel vertical faces 55a, parallel to the direction of movement, two inclined vertical faces 55b, inclined with respect to the direction of movement. , an anterior vertical face 55c forming a stop in contact with the elastic means 56 and a rear vertical face 55d connected to the chain and forming a stop. The faces 55a form a means of changing the state of the ventilation means. The state change means is preferably in mechanical connection with the carriage, at least in certain configurations of the control device, in particular in a closed position of the movable panel.

Other components are arranged symmetrically, inner side to the local and outside the room, and then have the same reference. For example, the first ventilation hole 19 exists both on the outside of the room (assumed at the top of the figure) and on the inside of the room (assumed below in the figure).

On each side of the window, the first locking hole 18 and the second locking hole 28 are superimposed and the bolt 31 is engaged in these two holes. An elastic fastener 32, belonging to the locking means 30, connects the bolt to the upper horizontal crosspiece and tends to push it towards the median vertical plane thereof. However, this elastic action is here thwarted by the carriage, whose two parallel vertical faces force each bolt to remain engaged in the locking holes. As a result, the upper horizontal cross member 27 can not move relative to the upper horizontal frame 17. The movable panel is locked relative to the frame.

In this locked position, the ventilation holes are superimposed vis-à-vis and allow a free passage of air between the outside and the inside of the room, through the window. An elastic seal 41 extends, internally to the upper horizontal crosspiece, each second ventilation hole 29 which it takes the form. An air duct is thus created through the first ventilation hole, the second ventilation hole and the elastic seal.

Figure 9 shows partially and schematically a horizontal section of the device in the locked-sealed state. The chain pushed the carriage, which had the effect of forcing more the elastic means 56, since the movable panel is immobilized, both by the right vertical frame and by the locking means, or by only one of these elements . Each parallel vertical face of the carriage is always in contact with the bolt 31 and thus maintains the locking. The cart is now facing the ventilation holes. The elastic seal 41 is now in contact with the parallel vertical face of the carriage, which obstructs the air duct.

Alternatively, the elastic seal is protruding outwardly of the upper horizontal crossbar, and the pressure exerted by the carriage on the elastic seal creates a deformation thereof producing a seal between the first ventilation hole and the second ventilation hole. .

Figure 10 shows partially and schematically a horizontal section of the device in the semi-open state. This time, the chain pulled the cart to the left. The movement of the carriage to the left has first released each bolt 31, brought inwardly of the upper horizontal crosspiece by the elastic fastener 32, then the rear face 55d of the carriage is in abutment with the inner face 22a of the left vertical upright and drove the entire moving panel in that direction. The locking holes and ventilation respective mobile panel and the frame are no longer vis-à-vis. The air can, however, flow between the outside and the inside of the room through these holes, but it is a very limited passageway with respect to the opening of the window caused by the movement of the movable panel. This intermediate state is, by nature, broken down. It is not locked.

The embodiment described in the figures above lends itself to many variants. For example, it is not necessary that there is permanent contact between the front face of the carriage and the elastic means. In the case of Figure 10 for example, the maximum extension of the elastic means could be such that this contact is broken. It suffices then that the elastic means has its own guiding device. In addition, an internal abutment could be added, for example immediately to the right of the elastic seal, so as to come into contact with the carriage when it moves to the right relative to the movable panel, to prevent the elastic means be totally compressed.

Finally, a second elastic means and / or a second internal stop may be arranged to limit the movement of the carriage to the left relative to the movable panel.

FIG. 11 represents, by way of example, an embodiment variant 25 without elastic means. The reference numbers are kept.

The carriage is movable between a first carriage stop formed by the inner face 22a of the left vertical post and a second carriage stop 27a disposed as described above immediately to the right of the elastic seal. The trolley moving area is such that it must be able to lock the locking means without action on the ventilation means and vice versa on the ventilation means without producing the unlocking. Each bolt 31 ends with a wheel 33, alternatively a ball, allowing the bolt to move without friction on the upper horizontal frame 17 (for the understanding, the roulette or ball is represented by a circle although the transverse dimensions are multiplied by 2 as in Figures 8 to 10).

The bolt serves as temporary stop the carriage when it moves to the right while the movable panel is not itself immobilized. The force transmitted by the chain is then transmitted to the assembly of the movable panel by each bolt and the second locking hole 28 and / or transmitted by the bolt and the elastic fastener 32.

When the movable panel abuts against the upright vertical frame, each bolt becomes free to engage in the first locking hole 18 and then releases the carriage which can either be stopped in a locking position with ventilation, or continue its movement up to the stop on the second carriage stop 27a, position in which the ventilation duct is closed by the carriage.

Alternatively, the second carriage stop is replaced by learning a sealed position, this sealed position corresponding to the position of the carriage when it closes the ventilation duct. The sealed position is identified by the electric actuator and / or by a counting means disposed in the wheel 53.

Figures 12A, 12B and 12C show a variant of natural ventilation means. This variant makes it possible to multiply the number of ventilation holes by means of a hatch or several ventilation hatches, arranged on the frame, on the movable panel, or distributed between these two elements. In all cases, it is the relative movement of the movable carriage relative to the movable panel when the latter is in closing abutment that causes the tilting of the ventilation flap from an open state to a closed state or vice versa. The ventilation hatch comprises a movable hatch 44 and a fixed hatch 45. The mobile hatch is connected to the carriage by a connecting means 46 in permanent engagement with the carriage or alternatively engaged with the carriage in a particular zone of movement of the carriage. this. The mobile hatch forms a means of changing the state of the ventilation means. The state change means is preferably in mechanical connection with the carriage, at least in certain configurations of the control device, in particular in a closed position of the movable panel. The movable hatch is provided with movable holes 47 while the fixed hatch is provided with fixed holes 48. The fixed holes are opposite the mobile holes in a first position of the carriage, represented in FIG. 12A, while the holes fixed are hidden by the movable door in a second position of the carriage, shown in Figure 12C. Figure 12B is an intermediate ventilation position obtained by a position of the carriage between the first position and the second position.

Figure 13 shows a method of controlling a closure device according to the invention. This method applies to a closure device comprising a vertical movable panel moving in a horizontal direction. The method applies in particular to the closure device described above.

In a first step S1, the movable panel is moved by means of the drive means connected to the carriage disposed in the movable panel and transmitting the force of the drive means to the movable panel.

In a second step S2, the activation of the locking means is controlled by the relative movement of the mobile carriage and the movable panel when the latter is in the closed position of the closure device.

In a third step S3, the activation of the ventilation means is controlled by the relative movement of the mobile carriage and the movable panel when the latter is in the closed position of the closing device. The order of execution of the second step and the third step can be reversed.

Locking can also be provided by means of disengaging the rollers 25 and 26. It is for example known from the state of the art to allow a relative vertical movement of the rollers relative to the rest of the movable panel, movement caused by the manipulation. a closing handle. When the rollers rise relative to the rest of the movable panel, it comes into contact with the base 16. The only friction of the panel with the base is an effective locking, which can be increased by complementary reliefs arranged on the lower horizontal crossbar and the base. To cause an effect equivalent to the relative movement of the casters in the case of fixed casters, it suffices that the rail 15 is split, a rail being assigned to each wheel and having a slight difference in height (a few millimeters) at the end of the journey, at the level of the closing position of the window: when arriving in the closed position, the movable panel descends by itself in contact with the pedestal.30 As a result, a large effort is required at the time of opening, since you have to lift a few millimeters the entire panel. The force to be provided during an opening movement involving unlocking the panel is therefore greater than when it is a closing movement.

However, a push-pull chain transmission naturally has a much lower performance in the direction of the thrust than in the direction of traction. This is known and can be explained simply by the fact that the thrust involves friction on the guiding means. The invention is therefore particularly suited to a combination of displacement of a movable panel and activation of its locking means using a single actuator device, since the actuator is required to provide a substantially equivalent power during a closing movement and during an opening movement with unlocking, the difference in transmission efficiencies offsetting the differences in actual effort requirements.

FIG. 14 represents a front view of a second closure device 100 'according to the invention, of rocking type, of general design similar to that of US Pat. No. 5,226,256, but for which a not shown actuator is used at the top of the window to control the pivoting with a push-pull chain. The window rotates around a horizontal axis X1-X'1.

Compared to the first device, common numerical references are retained which are simply assigned a prime sign when the function is similar and are marked with an asterisk sign when the function is opposite. A dotted line referenced F15-F17 delimits the upper zone of the window, comprising the control device 10 'shown schematically in vertical sections in FIGS. 15 to 17.

Figure 15 corresponds to a "locked-ventilated" state. The window comprises a movable panel 20 'and an upper horizontal frame 17' provided with a locking means formed of a hook 18'a and a hole 18'b cooperating with a bolt 31'a carried by a plate of locking 31 'b. When the latch is engaged within the latch hole, it is locked by it in a direction perpendicular to the plane of the figure and the window is latched as shown in FIG.

The movable panel comprises an upper horizontal cross member 27 '. In the upper horizontal crossbar circulates a carriage 55 'movable moving under the action of a chain 51' push-pull type or an equivalent flexible link. The chain is pushed or pulled by an actuator 52 'represented by a dotted circle, located in the upper horizontal frame. The chain enters the upper horizontal cross member by a not shown hole. A toothed wheel 53 'allows a guide of the chain in a rotation at right angles.

A first spring 32 ', represented in the form of 8 turns, is arranged between the locking plate and a horizontal T connected to the moving carriage. It tends to push the lock plate toward the moving carriage. A second spring 56 *, represented as 11 turns, is disposed between the movable carriage and a first stop B1.

A mobile hatch forms a means of changing the state of the ventilation means. The state change means is preferably in mechanical connection with the carriage, at least in certain configurations of the control device, in particular in a closed position of the movable panel. The movable door 44 'provided with a first opening 47' is in contact with a connecting means 46 'of the carriage. This movable door is pushed by a third spring 49 'disposed between the movable door and a third stop B3. It masks a fixed door 45 'provided with a second opening 48' in perfect coincidence, in this position of the mobile hatch, with the first opening. The window is in a locked and ventilated state.

Figure 16 shows the second device in a "locked-sealed" state. The actuator having pushed the chain, the movable carriage has moved to the right with respect to the preceding figure, and it is in contact with the locking plate. The bolt is however still engaged in the locking hole.

Likewise, the movable door has moved to the right and is in contact with a fourth stop B4. In this position, the first opening and the second opening no longer coincide and the air can not penetrate through the window.

It is possible to obtain, by any intermediate position of the carriage, a partial opening of the ventilation flap.

Figure 17 shows the second device in a "semi-open" state. The actuator pushed the chain again and thus the moving carriage and locking plate to the right. As a result, the bolt escaped from the locking hole. A second stop B2 limits the movement of the locking plate. If the actuator continues to push the chain, then the effect is to move the upper horizontal frame away from the upper horizontal beam, causing the movable panel to tilt gradually. In FIG. 17, the upper part of the movable panel is no longer in contact with the frame. For simplicity, however, the elements (18 ') belonging to the vertical section plane and the other elements belonging to a sectional plane comprising the pivot axis X1-X'1 and parallel to the panel have been represented in a single plane of figure. mobile. During a reverse movement of the chain, pulled by the actuator, it is important to cause the reverse tilting movement of the window, before moving the carriage: this is the role of the second spring 56 *, the stiffness must be high enough that the elastic force caused by this spring is greater than the component of the weight of the panel brought back on the chain, taking into account the reaction of the pivot axis. Pivoting angles remain low (10 to 30 ° maximum), this dimensioning constraint is easily achievable.

Note that the ventilation hatches are in a "sealed" position when the movable panel is semi-open. One could, simply by reversing the position of the openings 47 'and 48', obtain a "ventilated" state when the movable panel is semi-open. The table below summarizes the states of various means of the first closure device described above as a function of the position of the carriage vis-à-vis the movable panel: Moving panel Medium Ventilation locking means 1st position Closed On Off 2nd position Closed On On 3rd position Closed or Disabled Enabled if open panel or mobile closed ') open 20 4th position Closed On Partially enabled cl) In other cases (ie if the mobile panel is ajar or open), the Ventilation means can be activated or partially or completely closed by other means (such as the upper amount of the movable panel). This has no effect, in fact, when the mobile panel is open or ajar ventilation function is provided by the opening of the panel. Note that the different states of the closure device are determined by simple positions of the movable carriage relative to the frame of the closure device. Thus, it is easy to motorize such a closure device: it is sufficient to motorize the movement of the carriage with the aid of the drive device and to teach the drive device the different particular positions of the carriage with respect to the frame which allow to define the desired states of the closure device.

The control device 10 described above allows to maneuver and lock in position the movable panel. Nevertheless, the invention also relates to a control device whose function is only to operate the movable panel using a drive chain drive pushed and pulled. The invention further relates to a control device whose function is only to lock the movable panel in position using a chain drive device pushed and pulled.

Thanks to the invention, the ventilation means is activated by the same means as those activating the locking means and / or by the same means as those resulting in the closing or opening of the movable panel.

The chain 51 can be replaced by another flexible element pushed or pulled like a cable. The use of a flexible element pushed or pulled limits congestion.

A closed chain can also be used to move the movable carriage.

The invention has been described in the preferred case where the control device is integrated inside the closure device, the chain, the mobile carriage and the drive device being for example arranged inside a post vertical and horizontal crosspieces of a sliding window.

Alternatively, these three elements are integrated into a subassembly attached to the frame of an existing sliding window. It is sufficient to have two stops on the movable panel so that it can be driven by the movable carriage while allowing relative movement of the movable carriage relative to the movable panel.

The ventilation flap is operated during relative movement of the movable carriage relative to the movable panel. It can then cover an air duct outside the sliding window, for example made above the window, in the wall surrounding the window.

Such an arrangement is particularly suitable for renovation and it has the advantage of maintaining the thermal and sound insulation properties of the initial closure device.

Throughout this document, the terms "first", "second", "third" and "fourth" have a distinctive meaning; they have no temporal or spatial meaning.
