Description

ROLLING SHUTTER FOR BUILDING OPENING

The invention relates to shutters associated with building openings, such as doors or windows.

The use of exterior shutters attached to doors or windows is widely used in the building industry. An outer shutter is interposed between an opening and the external environment. Shutters in the closed position thus provide thermal, sound and visual insulation through the opening. The closed position of the shutter thus makes it possible to provide privacy inside the home, to secure the building against intrusions (especially on the ground floor), to limit heat exchanges to avoid a heating up. excessive in summer or loss of heat in winter, to protect the opening against bad weather or to limit the brightness inside the habitat. On the other hand, shutters in the open position allow solar radiation to penetrate into the habitat. Among the accessories of a building, the shutters are major components for dynamically managing both the energy exchange of the building with the exterior and the visual or acoustic comfort achieved by the building.

A large number of shutters on the market are in the form of shutters. The shutter comprises a set of opaque blades connected to each other to form a shutter wall in the closed position. The shutter wall formed is then located outside the opening. The blades are wrapped around a tree and housed in a box in the open position. The blades are selectively wound on a drum to open the shutter, or unwound from the drum to close the shutter. The drum drive can be performed from the inside manually by means of a crank or electrically by means of a gear motor controlled by the user.

US3089540 discloses a roller shutter having a shutter wall rotated by a shaft. The shutter is configured so that a continuous rotation of the shaft in the same direction of rotation successively deploys the shutter wall disposed in a first plane, and then retract this first plane. The wall can also be deployed in a second plane.

Especially in winter, the roller shutter user can not simultaneously benefit from optimum heating by external radiation (by keeping the shutter wall hidden) and increased privacy and security against intrusions ( keeping the shutter wall extended).

The invention aims to solve this drawback. The invention thus relates to a rolling shutter for a building opening, comprising:

a retractable shutter wall movable between a retracted position and an extended position;

a device for driving the closure wall between the retracted position and the deployed position; a guiding device selectively guiding the closure wall in a first stroke between the retracted position and a deployed position in a first plane or in a second race between the retracted position and a deployed position in a second plane parallel to the first plane; guiding device being configured to selectively switch the displacement of the closure wall according to the first stroke or the second stroke.

The roller shutter further comprises:

a shaft driven by the device for driving in rotation about an axis, the closing wall in the retracted position being wound on this shaft, the shaft being configured to be driven selectively in a direction of rotation of retraction or in a direction of rotation of deployment of the closure wall, the directions of rotation of retraction and deployment being opposite;

a deployment switching stop, the closure wall in the retracted position being configured to alternately come into contact with the deployment switching stop during a continuous rotation of the shaft in the direction of rotation of retraction, the deployment switching stop guiding the wall in the second stroke when the wall is in contact with the deployment switching stop and the shaft is driven in the direction of deployment rotation, the wall being guided in the first stroke when the wall is not in contact with the deployment switching stop and that the shaft is driven in the direction of deployment rotation.

According to one variant, the shutter comprises a box in which the shut-off wall is housed in the retracted position and from which the shut-off wall projects into said deployed positions, the first and second openings being formed in the box to enable the displacement of the shutter wall. the shutter wall respectively according to the first and second strokes, the shutter further comprising an isolation device closing the first opening when the wall is moved in the second stroke and closing the second opening when the wall is moved according to the first race.

According to another variant, the roller shutter comprises a brushing device housed in the box and rubbing against the closure wall when the latter is moved in one of said races.

According to another variant, the roller shutter comprises slides disposed directly above the box guiding the shutter wall respectively according to the first and second races.

According to yet another variant, the closure wall is completely retracted inside the box in the retracted position.

According to one variant, the closure wall has a face forming a solar thermal collector.

According to another variant, the wall comprises a plurality of blades hinged together about axes parallel to the axis of the shaft, the blades being interconnected with a deflection and being configured to provide openings between them when the blades are spaced apart and to close these openings when the blades are close together.

According to another variant, the drive device comprises a geared motor configured to selectively drive the shutter wall to the retracted position or to the deployed position and a control circuit of the geared motor having a control interface accessible to a user to receive a control retraction or deployment of the wall.

According to yet another variant, the stop is disposed vertically above the wall wound in the retracted position and is offset laterally with respect to the axis of rotation of the shaft.

According to a variant, the wall is configured to be urged by gravity towards a contact with the abutment

The invention further relates to a building opening, comprising:

a roller shutter as described above;

an opening glazing disposed between said first and second planes.

According to a variant, the opening comprises a shutter, the deployment switching stop being housed in the box, and one end of the wall being kept projecting with respect to the winding in the retracted position, a tilting control of the first race towards the second race on the control interface inducing a prior rotation of the shaft in the direction of rotation of retraction of the wall by the shaft until the end of the wall comes into contact with the switching stop, then a rotation of the shaft in the direction of rotation of the wall.

According to another variant, a lower opening communicates the volume between the glazing and the wall with the volume at the rear of the wall when the closure wall is in the deployed position in the second plane and an upper opening communicates the volume between the glazing wall and the volume at the rear of the wall when the closure wall is in the deployed position in the second plane.

According to another variant, the opening comprises a shutter comprising an end stop in which the lower opening is formed, the control circuit interrupting the stroke of the wall in the second plane when one end of the wall comes in contact with the end stop and when blades are still spaced apart in the upper part of the wall so as to form an upper opening.

The invention further relates to a method for controlling a roller shutter of a building opening, comprising the steps of:

moving a retractable closure wall, by driving a shaft in rotation in a direction of retractable rotation, from a position deployed in a first plane to a retracted position where the closure wall is wound on the shaft guiding the wall in a first stroke;

rotation of the shaft in the direction of retraction rotation until the wall is brought into contact with a deployment switching stop;

when the wall is in contact with the deployment switching stop, displacement of the closure wall, by driving the shaft in rotation in a direction of rotation of deployment opposite to the direction of rotation of retraction, of the position retracted to a deployed position in a second plane parallel to the first by guiding the wall in a second race. Other characteristics and advantages of the invention will emerge clearly from the description which is given hereinafter, by way of indication and in no way limitative, with reference to the appended drawings, in which:

The invention proposes to control a roller shutter of a building opening, the roller shutter having a retractable shutter wall. Control of the roller shutter is performed by guiding the deployment of the shutter wall selectively in a first race outside the opening and in a second race inside the opening. Each stroke of the wall is defined between a retracted position and an extended position, the deployed positions being arranged in parallel and distant planes. The wall in the retracted position is wound on a shaft driven by the device for driving in rotation about an axis, selectively in a direction of rotation of retraction or in a direction of rotation of deployment, these directions being opposite. The roller shutter further comprises a deployment switching stop, the wall in the retracted position being configured to alternatively come into contact with the deployment switching stop during a continuous rotation of the shaft in the direction of rotation of retraction. . The deployment switching stop guides the wall in the second stroke when the wall is in contact with the deployment switch stop and the shaft is driven in the direction of deployment rotation. The wall is guided in the first race when the wall is not in contact with the deployment switching stop and the shaft is driven in the direction of rotation of deployment.

The invention makes it possible to have the traditional functions of a shutter, namely a selective concealment through the opening, the selective penetration of the external light, the selective protection against break-ins, and a selective thermal transmission. In addition, this roller shutter allows to benefit from a greenhouse effect in a configuration where the wall is inside, which allows to benefit selectively from a contribution of energy coming from outside by transforming the solar radiation in heat. A roller shutter user will thus be able to time benefit from a supply of energy from outside in winter without requiring to make visible the interior of the building and without degradation of the security against the intrusion.

Figure 1 is a front view of a building opening 202 provided with a shutter 100 according to the invention. Figure 2 is a side sectional view of the same opening 202. The opening 202 is a glazed window disposed in an opening in a wall 201 and providing access to the interior of a building. The opening 202 comprises a glazing 203 mounted in a frame 204. Although the invention is illustrated in its application to a window, the invention naturally applies to any other type of building opening such as a door , or a French window.

The roller shutter 100 comprises a box 110 disposed in the upper part of the opening of the wall 201. The box 110 is intended to house a retractable closing wall 120. The closing wall 120 comprises, in a manner known per se, blades. opaque 121 hinged together. The closure wall 120 is movable between a retracted position inside the box 110 and an extended position.

As illustrated in FIG. 3, the shutter 100 comprises a device for driving the closure wall 120 between the retracted position and the deployed position. The drive device comprises, in a manner known per se, a shaft 130. The shaft 130 extends in the transverse direction of the opening of the wall 201. The shaft 130 is rotatably mounted in bearings 131 and 132. 130 is designed to allow the winding of the wall 120 around it, when the shaft 130 is rotated. In the retracted position, the closure wall 120 is wound on the shaft 130. The blades 121 of the wall 120 are hinged together about axes parallel to the axis of the shaft 130, to allow their winding. Advantageously, the blades 121 are also interconnected with a displacement in known manner: the blades are configured to provide openings 123 between them when they undergo a spreading force, and configured to close these openings 123 when these blades 121 are close together. The wall 120 has a lower end blade 122 having a free edge.

The shaft 130 can be rotated or in a direction of rotation of retraction of the wall 120, or in a direction of rotation of the wall 120. The shaft 130 is advantageously rotated by means of a geared motor 150 controlled by a control circuit 151. The geared motor 150 and the control circuit 151 are housed inside the box 110. The geared motor 150 selectively drives the wall 120 to the retracted position or to a position deployed as will be detailed later. The control circuit 151 is advantageously associated with a remote control 210 or a wall switch block to form a control interface accessible to a user. The remote control 210 has for example buttons 211 through which the user can control a retraction or deployment of the wall 120, inside or outside the building.

The shutter 100 comprises a guiding device for selectively guiding the closure wall 120 in a first stroke between the retracted position and a deployed position in a first outer plane, or in a second stroke between the retracted position and a position deployed in a second interior plane. The deployment positions of the wall 120 are located on either side of the glazing 203, delimiting the inside of the outside. The foreground and the second plane are parallel and distant. The guiding device is configured to selectively switch the displacement of the shutter wall 120 according to the first stroke or the second stroke. The closure wall 120 can thus advantageously be deployed inside or outside the building.

The guiding device advantageously comprises two pairs of slides 111, disposed perpendicularly to the casing 110 and guiding the closure wall 120 respectively according to the first and second strokes. The slides 111 maintain for this purpose side edges of the wall 120 to allow to deploy the closure wall 120 in said first and second planes.

The shutter 100 comprises an end stop 205 disposed at the rear of the window 202. The end stop 205 defines the lower sliding position of the wall 120 in the second plane. The end plate 122 is thus intended to come into contact with the end stop 205 when the wall 120 is fully deployed inside the building. The limit stop 205 may be provided with a sensor for detecting a contact between it and the end plate 122 for management of the automation by the circuit 151. The end stop 205 may be realized in the form of a bar extending transversely in the lower part of the opening in the wall 201.

The shutter 100 is advantageously mounted in the opening of the wall 201 so as to form a lower opening placing in communication the volume between the glazing 203 and the wall 120 with the volume at the rear of the wall, when the wall 120 is in the deployed position in the second plane. In the illustrated example, the lower opening is obtained by providing a vertical space 206 between the wall 201 and the abutment 205, and by providing a horizontal space 207 between this abutment 205 and the frame 204 of the opening 202.

The sectional view of the interior of the box 110 in FIG. 4 illustrates additional details of the guide device according to this embodiment. The caisson 110 has lower walls 141 and 142. The walls 141 and 142 each comprise a first opening 161 disposed above said first plane. The opening 161 thus allows the sliding of the closing wall 120 projecting outside the box 110 in the first plane. The walls 141 and 142 each comprise a second opening 162 disposed above the second plane. The opening 162 thus makes it possible to slide the shut-off wall 120 projecting outside the box 110 in the second plane.

The guide device advantageously comprises a guide channel 133. The guide channel 133 is disposed above and in line with the openings 161. The guide channel 133 also has a section converging towards the openings 161, so as to receive the lower end plate 122 of the wall 120 and lead precisely to the openings 162 when the wall 120 passes from its retracted position to its deployed position in the first plane. The guide device further comprises a stop 134 for switching the deployment of the wall 120 as will be detailed later. The stop 134 is advantageously arranged lower than the shaft 130 and the wall 120 wound. The stop 134 is advantageously disposed in line with the wall 120 wound in the retracted position and is advantageously offset laterally with respect to the axis of rotation of the shaft 130. The stop 134 is advantageously in the form of a transverse shaft (of which the section may be non-circular) disposed substantially vertically above the openings 162. A guide blade 135 is disposed more towards the interior of the building with respect to the stop 134, and substantially vertically above the openings 162. The blade 135 is inclined in order to guide the wall 120 towards the openings 162 when the wall 120 is in contact against the stop 134.

It is possible to use, in place of or in addition to the guiding groove 133, external slides 111 whose upper opening is flared so as to catch the end plate 122, then lead it towards the middle part of the slides 111 during its sliding. It is possible to use, in place of or in addition to the abutment 134, inner slides 111 whose upper opening is flared so as to catch the end plate 122, then lead it towards the middle part of the slides 111 during its sliding.

To prevent the casing 110 from causing unwanted heat exchange between the inside and the outside, the shutter 100 advantageously comprises a thermal insulation device selectively closing an opening 161 or an opening 162, depending on the position of the shutter wall 120. The shutter device illustrated comprises a movable shutter 140 slidably mounted between the walls 141 and 142. The shutter 140 is driven by a motorization not illustrated controlled by the control circuit 151. L shutter 140 can slide to a first position in which it closes the openings 161 and thus prevents an air flow from the outside of the building to the inside of the box 110. In this first position, it allows the wall 120 of through the openings 162. The shutter 140 can also slide to a second position in which it closes the openings 162 and thus prevents a flow of a In the second position, it allows the wall 120 to pass through the openings 161.

FIGS. 5 to 8 illustrate the deployment of the wall 120 between its retracted position and an unfolded outer position closing the window 202 integrally. In FIG. 5, the roller shutter 100 is in the retracted position inside the casing 110. position, the wall 120 does not interfere with the light transmission through the glazing 203 and does not affect the heat exchange between the interior and exterior of the building. The roller shutter 110 receives a control of deployment of the wall 120 to the outside. The shutter 140, initially closing the apertures 161, is moved to release these apertures and to seal the apertures 162. The directions of rotation of the shaft 130 will be described for the sectional views shown. As illustrated in FIG. 6, the shaft 130 is rotated in an anti-clockwise direction (direction of deployment) by the gearmotor 150. The end blade 122 is placed in the channel 133 so as to be guided by The end plate 122 then passes through the openings 161 and begins to slide in the first plane, placed outside the building. In Figure 7, the rotation of the shaft 130 is continued in a counterclockwise direction. The wall 120 is then in an intermediate deployment position. This position of intermediate deployment can advantageously be maintained by the control circuit 151. In this position, the wall 120 blocks a portion of the light transmission through the glazing 203. In this position, the wall 120 thus provides a certain privacy within the building, avoids excessive brightness to the interest of the building and provides some protection against intrusion. The interior of the building, however, benefits from some illumination coming from the outside through the openings 123 and through the opening formed under the end blade 122. In FIG. 8, the rotation of the shaft 130 in the anticlockwise direction is continued until the wall 120 is fully deployed in the foreground. In this position, the end plate 122 abuts against the wall 201. The blades 121 are then brought together and joined, so that the openings 123 are closed. Thus, the transmission of light energy through the glazing 203 is avoided and the heat exchange between the outside and inside of the building is minimal (the glazing 203 forms a thermal insulation behind the wall 120). The opening 202 can be opened while enjoying the protection of the wall 120 against intrusions.

Figures 9 to 12 illustrate the deployment of the wall 120 between its retracted position and a deployed lower position closing the window 202. In Figure 9, the roller shutter 100 is in the retracted position inside the box 110. The roller shutter 110 receives a deployment command of the wall 120 inside. The shutter 140, initially closing the openings 162, is moved so as to release these openings and to close the openings 161. As illustrated in FIG. 10, the shaft 130 is rotated in a clockwise direction (direction of retraction ) by the gearmotor 150. The wall 120 is configured so that by continuing to drive the shaft 130 in rotation in a clockwise direction (direction of retraction), it comes into contact with the switching stop 134. If the rotation of the shaft 130 in clockwise direction was continued continuously, the wall 120 would come into alternating contact with the abutment 134. The wall 120 is here advantageously configured to be urged by the earth's gravity towards the contact with the abutment 134. The rotation is continued until the end blade 122 comes into contact against the deployment switch stop 134. The stop 134 holds the end blade 122 in line with the openings 162. As shown in FIG. 11, the shaft 130 is then rotated anti-clockwise by the gear motor 150. The end blade 122, possibly guided by the guide blade 135, passes through the openings 162. The drive of the shaft 130 in the anti-clockwise direction is continued to the intermediate deployment position illustrated in FIG. 11. In this position, the The interior of the building benefits from a greenhouse effect between the glazing 203 and the wall 120. The air present between the wall 120 and the glazing 203 is heated by the solar rays. In addition, because of the openings 123 and the space under the end plate 122, heating of this air generates an air flow as illustrated by the dotted arrow. This airflow distributes the heat recovered inside the building. This intermediate deployment position makes it possible to benefit from an illumination coming from the outside. The intermediate deployment is particularly advantageous in winter when the angle of incidence makes the sunlight more dazzling. This is particularly advantageous for south-facing openings with large dimensions in bioclimatic habitats. This intermediate deployment position can advantageously be maintained by the control circuit 151. In Figure 12, the rotation of the shaft 130 in the anti-clockwise direction is continued until the wall 120 is fully extended in the second plane.

A deployment of the wall 120 in the second plane (that is to say inside the building) can be particularly advantageous, especially in winter. Thus, the building can benefit from a heat input while at the same time benefiting from an increased level of security against intrusions, and enjoying privacy from the outside.

Advantageously, the control circuit 151 interrupts the rotation of the shaft 130 when the wall 101 reaches the extended position illustrated in FIG. 12. In this position, the lower blades 121 are joined, while the upper blades 121 are spread apart to discover 123. The open openings 123 thus form an upper opening of the wall 120. Thus, even in this position of integral deployment, it is possible to benefit from a flow of heated air inside the building, the flow passing through the openings 206, 207, by the air gap between the wall 120 and the glazing 203, and by the openings 123.

Figures 13 to 15 illustrate the operation of the shutter 100 when a user controls the tilting of the wall 120 from the inside to the outside. The wall 120 is previously retracted by a rotation of the shaft 130 in a clockwise direction. Once the wall 120 is wound on the shaft 130 inside the box 110, the shutter 140 is moved from its closed position of the openings 161 to its closed position of the openings 162. The wall 120 is then deployed out through the openings 161 by means of a rotation of the shaft 130 in an anti-clockwise direction.

Moreover, in order to optimize the greenhouse effect and the heat energy recovery when the wall 120 is deployed in the second plane inside the building, this wall 120 advantageously has a face forming a solar thermal collector in this configuration. A solar thermal collector transforms light energy into heat. A solar thermal collector may in particular be produced by means of a specific coating deposited on this face of the wall 120. A solar thermal collector may also be made by a suitable choice of the constituent material of the blades 121, for example a metal treated to present a dark colored surface.

Advantageously, the roller shutter 100 comprises a brushing device 136 housed in the box 110. The brushing device 136 is configured to rub against the closure wall 120 when the latter is moved in the first race or the second race. A brushing device 136 is particularly advantageous, since the same closure wall 120 can be selectively brought from the outside of the building inwards, potentially with dirt that may have been deposited on the blades 121. The device brushing 136 thus avoids dirtying the interior of the building. The brushing device 136 comprises in this case brushes extending at the openings 161 and 162 of the wall 141. Brushes may also be arranged at any suitable place, for example advantageously only at level of the openings 161, in order to keep the dirt removed from the blades 121 outside the box 110.

When the wall 120 is retracted, it is advantageously housed integrally inside the box 110, no stop preventing the penetration of the end plate 122 inside the box 110.

The sectional view of the interior of the box 110 of FIG. 16 illustrates a variant of roller shutter. This shutter 100 generally has the same characteristics as the shutter illustrated in Figure 4. In this embodiment, the shutter 140 has a greater width to promote the thermal insulation provided at the box 110.

Although it has been described a command carried out by a user by means of a remote control, it is also conceivable that the operation of the roller shutter 100 is managed by a home automation system according to parameters for optimizing the heat exchanges with the controller. 'outside.

Building opening according to claim 11, comprising a shutter (100) according to claims 7 and 8, wherein the deployment switching stop (134) is housed in the box (110), and in which one end of the wall is kept projecting with respect to the winding in the retracted position, a tilting control of the first stroke towards the second stroke on the control interface inducing a prior rotation of the shaft (130) in the direction of rotation retracting the wall by the shaft until the end (122) of the wall comes into contact with the switching stop (134), then a rotation of the shaft in the direction of rotation of deployment of the wall.

13. Building opening according to claim 11 or 12, wherein a lower opening (206,207) communicates the volume between the glazing (203) and the wall (120) with the volume at the rear of the wall when the wall shutter is in the deployed position in the second plane and in which an upper opening communicates the volume between the glazing wall and the volume at the rear of the wall when the closure wall is in the deployed position in the second plan.

14. Building opening according to claim 13, comprising a shutter according to claim 7 and comprising an end stop (205) in which the lower opening (206) is formed, the control circuit (151) interrupting the stroke of the wall in the second plane when one end of the wall comes into contact with the end stop and when blades (121) are still spaced apart in the upper part of the wall so as to form an upper opening.

15. A method of controlling a rolling shutter of a building opening, comprising the steps of: moving a retractable shutter wall (120) by driving a shaft in rotation in a direction of rotation retraction, from a deployed position in a first plane to a retracted position where the closure wall is wound on the shaft guiding the wall in a first stroke;

rotation of the shaft in the direction of retraction rotation until the wall is brought into contact with a deployment switching stop; when the wall is in contact with the deployment switching stop, displacement of the closing wall (120), by driving the shaft in rotation in a direction of rotation of deployment opposite to the direction of rotation of retraction, from the retracted position to a deployed position in a second plane parallel to the first by guiding the wall in a second stroke.
