Description

Technical field

The present invention relates to the field of blackout devices and in particular to the field of devices for installing transom roller shutters.

Previous technique

In the field of roller shutter installation, it is known to install a box containing the shutter and its rolling mechanism in a transom above an opening such as a door or window. Access to the rolling mechanism and the shutter during maintenance operations, for example, is generally via the bottom of the box. This type of installation requires an operator wishing to carry out maintenance to intervene from the outside of the building and to use high-level intervention tools (particularly for windows on upper floors). Furthermore, to access the mechanism, it is often necessary to remove the casing of the box. This has the disadvantage of considerable time loss for the operator and a risk of injury from falling.

The document EP 1748413 A3 describes a device according to the preamble of claim 1.

Disclosure of the invention

The aim of the present invention is therefore to overcome the drawbacks mentioned above by proposing a device for a removable roller shutter, simple to install, and accessible from the inside of a building at human height.

• un coffre creux dans lequel est installé au moins un volet et des moyens permettant le roulement dudit volet autour d'un axe de roulement et présentant une fente s'étendant selon un axe parallèle audit axe de roulement et autorisant le passage dudit volet à l'extérieur du coffre, ledit coffre étant destiné à être installé dans une réservation de dimensions congruentes avec celui-ci, ménagée dans un mur de bâtiment et positionnée de sorte à surmonter un bâti d'une ouverture de type fenêtre ou porte séparant un espace extérieur au bâtiment d'un espace intérieur au bâtiment,
• des moyens de déplacement destinés à lier ledit coffre au mur et lui permettant de passer d'au moins une position dite de « mise en service » selon laquelle ledit coffre est dans la réservation et surmonte l'ouverture, à au moins une position dite de « maintenance » selon laquelle le coffre n'est pas dans l'encombrement de la réservation et est dans l'espace intérieur au bâtiment.

In accordance with the invention, there is therefore proposed a removable device for roller shutters, remarkable in that it comprises at least:

• a hollow box in which is installed at least one shutter and means allowing the rolling of said shutter around a rolling axis and having a slot extending along an axis parallel to said rolling axis and allowing the passage of said shutter outside the box, said box being intended to be installed in a reservation of dimensions congruent with it, arranged in a building wall and positioned so as to surmount a frame of an opening of the window or door type separating a space outside the building from a space inside the building,
• moving means intended to connect said box to the wall and allowing it to move from at least one so-called "commissioning" position in which said box is in the reservation and surmounts the opening, to at least one so-called "maintenance" position in which the box is not in the space of the reservation and is in the space inside the building.

A "roller shutter" is a curtain that is opaque or not. It may possibly be made up of an assembly of slats, generally made of metal, plastic or wood, intended to cover an opening, generally glazed, such as a window or door. The term "shutter" may be used to designate indifferently a device such as a shutter, mosquito net or blind.

A "slit" is a long opening.

A "reservation" is an opening made in a wall to accommodate a door or window (also called an embrasure).

The term "frame" refers to the frame/framework/sash of a glazed opening such as a door or window.

The "interior space of the building" is the space enclosed by the walls of the building when all doors and windows are closed.

The axis of rotation of the roller shutter is called the "rolling axis".

Preferably, the movement means comprise at least: sliding means intended to connect said box to the wall by a sliding connection and allowing the translation of said box from at least one “commissioning” position to at least one “maintenance” position located in the space inside the building, along an axis perpendicular to the rolling axis, said sliding means comprising at least first assembly means intended to assemble said sliding means to the wall, and second assembly means intended to assemble said sliding means to the box.

The wall considered is a wall of the building presenting the door or window type opening. This wall will be considered as substantially vertical in relation to the ground which is considered as substantially horizontal.

"Assembly means" are means used to connect two elements in a fixed or mobile manner. These two elements can therefore be connected in a fixed manner, they then do not have the possibility of being in movement relative to each other (example fixing by screw-type means) or mobile, they are articulated and can therefore be set in motion relative to each other (hinge for example).

More preferably, the sliding means consist of a rail fixed by first assembly means to the wall and a slide fixed by second assembly means to the trunk.

In another embodiment, said trunk passes from said “commissioning” position to said “maintenance” position and from said “maintenance” position to a second “maintenance position” by movement means, said movement means being means capable of allowing the trunk to pass from the “commissioning” position to the “maintenance” position by translation along an axis perpendicular to the rolling axis, and capable of allowing said trunk to pass from the “maintenance” position to the second “maintenance position” by translation along an axis parallel to the rolling axis, and in the direction of opening.

Alternatively, said movement means are capable of allowing said trunk to move from the “maintenance” position to the second “maintenance position” by rotation around an axis parallel to the rolling axis, and at an angle greater than or equal to 90°.

Advantageously, the movement means are a rail fixed by first assembly means to the wall and a slider assembled by second assembly means to the trunk, said trunk and said slider cooperating so as to allow rotation of said trunk around an axis parallel to the rolling axis, and at an angle of 90°.

Preferably, the slot is on a lower face of the box intended to be in contact with the frame and in that said slot opens onto the space outside the building.

Advantageously, the trunk has two opposite faces perpendicular to said lower face intended to be in contact with the wall and at least one of said two faces is associated with movement means.

The trunk preferably has a generally parallelepiped shape.

Preferably, the trunk has at least one removable wall so as to allow access to the shutter and to the means enabling rolling.

Best way to carry out the technical invention

• un coffre 2 creux dans lequel est installé au moins un volet et des moyens permettant le roulement dudit volet autour d'un axe de roulement R et présentant une fente 3 s'étendant selon un axe parallèle audit axe de roulement R et autorisant le passage dudit volet à l'extérieur du coffre 2, ledit coffre 2 étant destiné à être installé dans une réservation 10 de dimensions congruentes avec celui-ci, ménagée dans un mur 100 de bâtiment et positionnée de sorte à surmonter un bâti 110 d'une ouverture de type fenêtre ou porte séparant un espace extérieur au bâtiment d'un espace intérieur au bâtiment,
• des moyens de déplacement 20 destinés à lier ledit coffre 2 au mur 100 et lui permettant de passer d'au moins une position dite de « mise en service » selon laquelle ledit coffre 2 est dans la réservation 10 et surmonte l'ouverture, à au moins une position dite de « maintenance » selon laquelle le coffre 2 n'est pas dans l'encombrement de la réservation 10 et est dans l'espace intérieur au bâtiment.

In accordance with the Figures 1 to 4 , a removable device for roller shutter 1 is therefore described, remarkable in that it comprises at least:

• a hollow box 2 in which at least one shutter is installed and means allowing said shutter to roll around a rolling axis R and having a slot 3 extending along an axis parallel to said rolling axis R and allowing said shutter to pass outside the box 2, said box 2 being intended to be installed in a reservation 10 of dimensions congruent with the latter, arranged in a wall 100 of a building and positioned so as to surmount a frame 110 of an opening of the window or door type separating a space outside the building from a space inside the building,
• moving means 20 intended to connect said box 2 to the wall 100 and allowing it to move from at least one so-called “commissioning” position in which said box 2 is in the reservation 10 and surmounts the opening, to at least one so-called “maintenance” position in which the box 2 is not in the space of the reservation 10 and is in the space inside the building.

The reservation 10 is of congruent dimensions with the trunk 2, that is to say that it has dimensions adapted so that the trunk 2 can be housed in this reservation 10.

Preferably, the trunk 2 is housed in a tight manner in the reservation 10. The reservation 10 may be through or not. Advantageously, the reservation 10 is installed on the side of the interior space.

This box 2 can be in excess thickness, in excess thickness or be at the same level as the surface of the wall 100 in the “commissioning” position.

Inside the box 2, there may be a compartment with one or more shutters (or other types of equipment: blinds, mosquito nets, etc.) and their controls. Perimeter seals may be installed at the various contact areas between the box 2 and the wall 100 or the box 2 and the frame 110, for example, in order to ensure sealing with respect to the outside space.

The purpose of the movement means 20 is to connect the trunk 2 to the wall 100 while allowing the movement of the trunk 2 relative to the latter. They are fixed on any surface of the trunk 2 and the wall 100 but preferably, at the contact zones between the trunk 2 and the wall 100, inside the reservation 10. Preferably, the dimensions of the reservation 10 are chosen to accommodate the trunk 2, and the movement means 20, in a fitted manner.

In the “maintenance” position, trunk 2 is outside the footprint of reservation 10, i.e. it is outside reservation 10.

Advantageously, the reservation 10 is a through one. It can be made using an internal thermal insulation technique and can be closed on the external space side by a plate.

Preferably, the displacement means 20 comprise at least: sliding means intended to connect said box 2 to the wall 100 by a sliding connection and allowing the translation of said box 2 from at least one “commissioning” position to at least one “maintenance” position located in the space inside the building, along an axis perpendicular to the rolling axis R, said sliding means comprising at least first assembly means intended to assemble said sliding means to the wall 100, and second assembly means intended to assemble said sliding means to the box 2.

More preferably, the sliding means consist of a rail fixed by first assembly means to the wall 100 and a slide fixed by second assembly means to the trunk 2. Any other means or combination of means having this function are conceivable. They make it possible to move in translation of the trunk 2 along a substantially horizontal axis. The first assembly means are, for example, a metal plate or flange fixed to the wall 100 by screw-type means. The second assembly means are, for example, of the gluing, clip type or a combination of these means.

In another embodiment, said trunk 2 passes from said “commissioning” position to said “maintenance” position and from said “maintenance” position to a second “maintenance position” by movement means, said movement means being means capable of allowing the trunk 2 to pass from the “commissioning” position to the “maintenance” position by translation along an axis perpendicular to the rolling axis R, and capable of allowing the trunk 2 to pass from the “maintenance” position to the second “maintenance position” by translation along an axis parallel to the rolling axis R and in the direction of opening.

These types of particular movements have the advantage of allowing the trunk 2 to be freed from the space occupied by the reservation 10 by a first translation and then lowering the trunk 2 in height to allow easy maintenance, without being hindered by the floor or the ceiling above the reservation 10 and without needing to use tools for intervention at height. These means of movement can be combined telescopic slides for example. Any other means or combination of means having this function are conceivable here.

Alternatively, said movement means 20 are capable of allowing said box 2 to pass from the “maintenance” position to the second “maintenance position” by rotation about an axis parallel to the rolling axis R and at an angle greater than or equal to 90°. These types of particular movements have the advantage of allowing the box 2 to be released from the space occupied by the reservation 10 by a first translation and then to lower the box 2 in height. This is intended to facilitate access to a specific part of the box 2 and to allow intervention at human height. For example, if the box 2 has a removable hatch for access to the shutter and its rolling mechanism in a particular area, the angle of rotation can be chosen so that in the second “maintenance” position this frame is facing the user. These rotation means can be a pivot axis located on the slide for example. Any other means or combination of means having this function are conceivable here.

Advantageously, the displacement means 20 are a rail fixed by first assembly means to the wall 100 and a slider assembled by second assembly means to the trunk 2, said trunk 2 and said slider cooperating so as to allow rotation of said trunk 2 around an axis parallel to the rolling axis R, and at an angle of 90°. The advantage of this displacement means is that it allows with a simple structure to ensure both the translation and the rotation of the trunk. Other means 20 can be used to perform these two functions such as for example, a system with special hinges. Any other means or combination of means having this function are conceivable here.

Preferably, the slot 3 is on a lower face of the box 2 intended to be in contact with the frame 110 and said slot 3 opens onto the space outside the building. The slot extends along an axis parallel to the rolling axis R. It allows the passage and simultaneous or non-simultaneous unwinding, on single or double slides for example, of equipment such as shutters, blinds, or mosquito nets for sun protection or anti-parasites.

Advantageously, the trunk 2 has two opposite faces perpendicular to said lower face intended to be in contact with the wall 100 and at least one of said two faces has movement means 20.

The trunk 2 preferably has a generally parallelepiped shape. The trunk 2 may also have the shape of a drawer.

The walls of the box 2 are preferably designed in a thermo-acoustic material so as to ensure good thermal insulation of the building and to reduce noise pollution coming from outside the building. To limit heat loss, the box 2 can be insulated with rock wool or glass wool.

Preferably, the box 2 has at least one removable wall so as to allow access to the shutter and to the means allowing rolling. This removable wall allows access to the shutter and its rolling means for their repair or replacement by an operator responsible for maintenance.

The device 1 according to the invention can be used with a connected blind/shutter system, jointly controlling the opening and closing of a blind on the one hand and a shutter on the other hand, at night and during the day, depending on the temperatures and the sunshine conditions, so as to maintain good thermal insulation of the building.

The invention also relates to an assembly comprising a removable device for roller shutter 1 as described above, a through reservation 10 in a wall 100 of a building and an opening on which a door or window frame 110 is installed.

Finally, it goes without saying that the examples of devices 1 in accordance with the invention, which have just been described, are only particular illustrations, in no way limiting of the invention.
