Description

Title of the invention: Obstruction device, and cap-type sun visor, for opening the facade of a building TECHNICAL FIELD OF THE INVENTION

[0001] The field of the invention is that of the total or partial obstruction of openings in facades, in particular of buildings, such as windows, doors and French windows, as well as that of the protection of such openings from the sun.

[0002] More specifically, the invention relates to an obstruction and sunshade device, in particular of the cap type, for openings in facades, in particular buildings.

[0003] The invention finds applications in particular in the field of construction, whether for residential, industrial, or tertiary use in particular. The invention can also find applications in the field of vehicles, in particular land vehicles such as mobile home type vehicles or even marine vehicles such as ships. STATE OF THE ART

[0004] Different types of obstruction devices are known from the prior art for obstructing a facade opening.

[0005] On the one hand, there are sliding obstruction devices, for example sliding shutters, sliding folding panels, sliding folding shutters, etc., which can slide along a horizontal direction.

[0006] There are also swinging obstruction devices, such as swinging shutters which can pivot around a vertical axis.

[0007] Finally, there are also obstruction devices called roller shutters, made up of slats that can be rolled around a horizontal axis.

[0008] These devices can generally adopt an open position, in which the opening to be obstructed is uncovered, and a closed position, in which the opening to be obstructed is obstructed, i.e. covered, and can optionally adopt one or more intermediate positions between their open position and their closed position.

[0009] Thus, these devices can make it possible to modulate the obstruction of the opening according to needs, for example by choosing total obstruction at night, partial obstruction during the day when the opening is exposed to the sun, and no obstruction during the day when the opening is not exposed to the sun.

[0010] These devices thus have a function of regulating the interior temperature of buildings, by modulating the obstruction of the opening according to the weather conditions.

[0011] These devices also have a security function, by obstructing access to opening when in the closed position, preventing break-ins, but also damage caused by bad weather.

[0012] There are also awning or screen type devices which can be used to break or shield the sun.

[0013] These devices are generally fixed relative to the opening to be obstructed, and are either protruding from the facade or arranged at a distance from the facade, and thus cannot be arranged on all types of facades. They do not always meet the aesthetic and architectural criteria that must be satisfied when designing or renovating buildings.

[0014] Particularly in a context of climate transition, in which more and more regions in the world are exposed to episodes of intense heat, it is desirable to construct or renovate buildings by integrating solutions for obstructing openings which make it possible to regulate the interior temperature of buildings optimally, and which make it possible to respect architectural and aesthetic constraints in the context of their integration into a building, while providing the same advantages as conventional obstruction devices.

[0015] There is thus a need for an obstruction device which allows great versatility in the obstruction of facade openings, while meeting security and aesthetic constraints. Statement of the invention

[0016] The present invention aims to remedy all or part of the drawbacks of the state of the art cited above.

[0017] To this end, the invention relates to an obstruction and sunshade device for opening the facade of a building, such as a window, door, or French window, the device comprising: - a pre-frame intended to be fixed on the facade at the level of the opening to be obstructed, comprising a first lateral slide and a second lateral slide opposite each other; - an upper obstruction part and a lower obstruction part hinged to each other so as to be able to be folded and unfolded, the upper obstruction part being hingedly mounted on the pre-frame at a so-called upper end of the pre-frame, and the lower obstruction part being slidably guided in the first lateral slide and in the second lateral slide of the pre-frame, and wherein the upper obstruction portion comprises a horizontal sliding louver comprising an upper frame and an apron slidably guided in the upper frame between a closed position and an open position; the device being further configured to adopt at least: - a so-called obstruction configuration, total or partial, in which the apron is in one of its closed position, its open position or an intermediate position between its closed position and its open position, and in which configuration the upper obstruction part and the lower obstruction part are unfolded and are substantially aligned vertically in the extension of one another, so as to cover the opening to be obstructed; and - a so-called sunshade configuration, in which the apron is in its closed position, and in which configuration the upper obstruction part and the lower obstruction part are folded towards each other at the upper end of the pre-frame, so as to together form an awning extending away from said facade.

[0018] In the present disclosure and in the detailed description which follows, the term obstruction designates the fact of covering at least in part the opening of the building, in particular making it possible to prevent at least in part the light from penetrating into the building through the opening. The terms obstruction and concealment in particular can be considered as synonyms in the context of the present patent application.

[0019] The obstruction device according to the invention is remarkable in that it allows great versatility in the configurations of obstruction and protection from the sun of the opening which can be obtained.

[0020] When the device is in its obstruction configuration, the lower obstruction portion covers the opening to be obstructed at its lower portion. The upper obstruction portion may, depending on the position of the shutter, completely or partially uncover or obstruct the opening to be obstructed at its upper portion.

[0021] Such a configuration can for example be adopted to completely obstruct the opening during the night, when the shutter is closed, to partially obstruct the opening during the day, when the shutter is open or in an intermediate position, the lower obstruction part then partially protecting the opening from sunlight, and / or from being overlooked.

[0022] When the device is in its sunshade configuration, the lower obstruction part and the upper obstruction part uncover all or almost all of the opening to be obstructed (only the upper part can still be slightly covered), and together form an awning, or sunshade, sunshade or "cap", extending above the upper part of the opening to be obstructed, away from the facade.

[0023] Such a configuration can for example be adopted to completely or almost completely uncover the opening, for example during the day when significant brightness is desired, while benefiting from protection against sunlight, in especially zenithal sunlight.

[0024] Furthermore, the obstruction device thus produced in two parts can be adapted to the needs of a user, in particular by modulating the design of the device freely, by adapting the type of shutter chosen in the upper obstruction part, and the type of lower obstruction part.

[0025] For example, the device comprises a first articulation hinge fixed on the one hand to the upper obstruction part and on the other hand to the lower obstruction part, so that the upper obstruction part and the lower obstruction part are articulated with each other.

[0026] For example, the device comprises a second articulation hinge mounted on the pre-frame at the upper end of the pre-frame, and fixed to the upper obstruction portion, such that the upper obstruction portion is hingedly mounted on the pre-frame at a so-called upper end of the pre-frame.

[0027] In this example, it is said that the lower and upper obstruction parts are unfolded when they are substantially in the same plane on either side of the first articulation hinge, and folded when they are arranged angularly outside this same plane, and that they substantially face each other.

[0028] For example, in the sun visor configuration, the angle defined between the upper obstruction portion and the lower obstruction portion is about 0 to 30 degrees.

[0029] In this example, between the obstruction configuration and the sunshade configuration, the upper obstruction portion pivots about the second hinge pin about 70 to 90 degrees.

[0030] The device according to the invention finds an application in particular in the field of windows with glazed or solid sills, the sill designating the space located between the window and the ground, and which can be a masonry wall, but can also be framed. Unlike the transom which is the upper part of a window, the sill is the part which is located below a joinery and is a fixed part. The sill can be glazed and then serves to bring the sun's rays into the interior of the building, and can be presented in different styles including the opaque, transparent or even translucent model. The glass of this type of sill is generally reinforced with laminated glazing. A sill can however also be in the form of a panel (insulating or guardrail). As a general rule, windows with sills consist of an upper part like a French window and a lower part called a glazed (or solid) sill.

[0031] In such an application, the dimensions of the upper obstruction portion are preferably similar to those of the upper portion of a sill-type window (e.g. corresponding to the dimensions of the window portion at the French), that is to say that the upper obstruction part is adapted to substantially obstruct the upper part of the window of the window type with sill. The shutter can then ensure partial or total occultation of the French window (for example) by a progressive lateral pushback of slats that the apron comprises, in upper and lower rails.

[0032] Similarly, in such an application, the dimensions of the lower obstruction portion are preferably similar to those of the glazed or solid sill, i.e. the lower portion of a sill-type window.

[0033] Other embodiments of the obstruction device according to the invention, which are particularly convenient and advantageous, and can be freely combined in any technically effective combination, are described below.

[0034] According to a preferred embodiment, the upper frame comprises an upper rail and a lower rail on which the apron can slide, and the device comprises one or two locks mounted on the lower rail, making it possible to lock the apron in the closed position.

[0035] Thus, when the device is in its “total” obstruction configuration, i.e. with the shutter closed, the locks, which preferably have a suitable horizontal rod, make it possible to laterally block the shutter in the closed position by anchoring it at the two lateral slides of the pre-frame. The device and the building can thus be protected against intrusion attempts.

[0036] According to a preferred embodiment, the apron comprises at least two side leaves each composed of at least two vertical slats articulated to each other by their adjacent vertical sides.

[0037] According to a preferred embodiment, the vertical blades are made of metallic material, preferably aluminum.

[0038] According to a preferred embodiment, the vertical blades are perforated.

[0039] According to a preferred embodiment, the lower obstruction part comprises a lower frame and a filler panel mounted in the lower frame.

[0040] According to an advantageous embodiment, the filling panel is a glass panel, or a preferably openwork metal panel.

[0041] According to a preferred embodiment, the device further comprises at least one holding member configured to hold the device in its sun visor configuration.

[0042] Thanks to these provisions, the device can be maintained in its sun visor configuration, in particular against the effect of gravity which tends to return the device to its obstruction configuration.

[0043] According to an advantageous embodiment, the holding member comprises a compressed gas cylinder, comprising a cylinder body which is mechanically secured to the lower obstruction part, and a cylinder rod which is mechanically secured to the pre-frame.

[0044] According to an advantageous embodiment, the holding member comprises a spring mechanically secured on the one hand to the lower obstruction part, and on the other hand to the pre-frame.

[0045] According to an advantageous embodiment, the holding member comprises a cable-pulley type mechanism, comprising a counterweight, a first cable and a second cable extending respectively in the first lateral slide and in the second lateral slide, each of the cables being mechanically connected on the one hand to the lower obstruction part, and on the other hand to the counterweight.

[0046] According to a preferred embodiment, the device further comprises an actuator configured to be able to move the upper obstruction part and lower obstruction part so as to allow the device to move from its obstruction configuration into its sun visor configuration, and vice versa.

DETAILED DESCRIPTION OF THE INVENTION

[0048] The present description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

[0049] It should be noted, from now on, that the figures are not necessarily to scale.

[0050] In the following description, the terms “upper” and “lower” are used to designate high and low relative positions along a substantially vertical axis relative to the ground, when the device according to the invention is installed in a building. A dimension in the substantially vertical direction is called "height", and a dimension in a substantially horizontal direction, orthogonal to the vertical direction and parallel to the facade of the building is called "width".

[0051] Figures 1, 2 and 3 show from the front and schematically an obstruction and sunshade device 1 according to the invention, in a configuration known as obstruction of an opening 2 of a building facade 3, the opening 2 here being a window.

[0052] The device 1 comprises a frame, called pre-frame 4, an upper obstruction part 5 mounted in an articulated manner on the pre-frame 4, and a lower obstruction part 6 articulated with the upper obstruction part 5, so that the upper obstruction part 5 and the lower obstruction part 6 can be folded towards each other, and unfolded. The lower obstruction part 6 can slide vertically at two lower points along the pre-frame 4.

[0053] The upper obstruction part 5 comprises a horizontal sliding shutter 7, comprising an apron 8 which can slide between a closed position, in which the shutter 7 is fully closed, and an open position, in which the shutter 7 is fully open.

[0054] In Figures 1 to 3, the upper obstruction part 5 and the lower obstruction part 6 are unfolded and are aligned in the extension of one another, here one above the other, that is to say in a substantially vertical direction.

[0055] In [Fig.l], the device 1 completely obstructs the opening 2. The lower obstructing part 6 obstructs the lower part of the opening 2, and the apron 8 is here in its closed position, so that the upper obstructing part 5 completely obstructs the upper part of the opening 2.

[0056] In [Fig.2], the device 1 partially obstructs the opening 2. The lower obstructing part 6 obstructs the lower part of the opening 2, and the apron 8 is here in an intermediate position between its closed position and its open position, so that the upper obstructing part 5 partially obstructs the upper part of the opening 2.

[0057] In [Fig. 3], the device 1 also partially obstructs the opening 2. The lower obstructing part 6 obstructs the lower part of the opening 2, and the apron 8 is in its open position, so that the upper obstructing part 5 uncovers the upper part of the opening 2, which is thus substantially not obstructed.

[0058] [Fig.4] shows from the front and schematically the obstruction device 1 in a so-called sun visor configuration.

[0059] In this configuration, the apron 8 is in its closed position, and the lower obstruction part 6 and the upper obstruction part 5 are folded towards each other so as to form together a canopy 9 extending away from the facade 3, and the device 1 does not substantially obstruct the opening 2.

[0060] [Fig.5] shows in more detail the device 1 according to an embodiment given as an example, according to a front view.

[0061] Figures 6 and 7 show the device of [Fig.5] in a sectional view, respectively in an elevational section, that is to say in a vertical sectional plane orthogonal to the facade 3, and a transverse section, that is to say in a horizontal sectional plane.

[0062] The views in Figures 6 and 7 are interrupted, that is, certain parts of the lower obstruction part 6 and the upper obstruction part 5 are not shown, the interruption being represented by two parallel wavy lines.

[0063] Furthermore, [Fig.7] only represents one half of the device 1 and the opening 2, the other half being substantially identical.

[0064] The pre-frame 4, also called the sleeping pre-frame, here comprises four profiles delimiting the pre-frame 4.

[0065] The pre-frame 4 comprises two lateral profiles 11 and 12, an upper profile 13 and a lower profile 14.

[0066] The pre-frame 4 is mechanically fixed to the facade, for example by screwing, either inside the opening 2 (fixing under the lintel), or on the facade at the edge of the opening 2.

[0067] For example, the pre-frame 4 is fixed by the upper profile 13 to the facade, for example by fixing in the frame of a window 15 installed in the opening 2.

[0068] The upper obstruction part 5 comprises the shutter 7 which has an upper frame 16 in which the apron 8 is mounted, and the lower obstruction part 6 comprises a lower frame 17.

[0069] The upper frame 16 and the lower frame 17 are connected by an articulation that the device 1 comprises, formed here by a first hinge 18. Preferably, the first hinge 18 is continuous over the entire width of the upper obstruction part 5 and the lower obstruction part 6.

[0070] The upper frame 16 is hingedly connected to the pre-frame 4 at a so-called upper end 10 of the pre-frame 4, by means of a second hinge 19, called a projection hinge, preferably extending over the entire width of the upper obstruction part 5.

[0071] The lower frame 17 is slidably guided, at two lower points, in the lateral profiles 11 and 12 which here form lateral slides or runners for the lower obstruction part 6, and which are opposite each other.

[0072] In other words, the upper frame 16 and the lower frame 17 are hinged to each other, the upper frame 16 is hinged to the pre-frame 4, while the lower frame 17 can slide on the pre-frame 4 and follow the movement of the upper frame 16 when the latter pivots around the second hinge 19.

[0073] The upper obstruction part 5 and the lower obstruction part 6 together form an “accordion” type device which can be folded towards the upper part 10 of the pre-frame 4.

[0074] The upper obstruction portion 5 will now be described in more detail.

[0075] The upper frame 16 of the upper obstruction part 5 here comprises a first lateral edge 20 and a second lateral edge 21, an upper rail 22 and a lower rail 23, together delimiting the upper frame 16.

[0076] In the example illustrated, the upper profile 13 of the pre-frame 4 comprises a first bead 24 extending longitudinally projecting from the upper profile 13, and the upper rail 22 of the upper frame 16 comprises a first upper longitudinal groove 25, in which the first bead 24 is housed, so as to form the second hinge 19.

[0077] The apron 8 of the shutter 7 is formed of two leaves 26. Each leaf 26 is composed of at least two vertical slats 27, having their adjacent vertical sides 28 articulated and coupled to each other by a joining element 29, for example a hinge. In the example illustrated, the joining element 29 is such that it forms a continuous interlocking over the entire height of the leaves 26.

[0078] Two of the vertical blades 27, called edge blades, are mounted to rotate respectively on the first lateral edge 20 and the second lateral edge 21.

[0079] The vertical blades 27 are for example made of aluminum, preferably 16 / 10ths thick.

[0080] In the example illustrated, the vertical blades 27 are perforated and here comprise ventilation slots 35. The ventilation slots 35 can be arranged at different pitches, for example according to a slot / material ratio of 1 / 3, 2 / 3, or even 3 / 3.

[0081] Each leaf 26 of the shutter 7 is suspended by at least one carriage 30 capable of cooperating by sliding with the upper rail 22 of the upper frame 16, between the closed position and the open position of the shutter 7. For example, the carriages 30 have two rigid bearings 31, typically made of stainless steel, which can be for example of the single-row ball type. The tracks of these bearings 31, formed in the upper rail 22, consist of a groove of sufficient depth to make them capable of supporting combined radial and axial loads in both directions of movement of the leaves 26.

[0082] The carriages 30 can be made by die-casting and advantageously made of Zamak, that is to say an alloy of Zinc, Aluminum, Magnesium and Copper. Such an alloy gives the carriages high mechanical properties and excellent resistance to corrosion.

[0083] At their lower part, the leaves 26 of the shutter 7 each comprise a shoe 32, for example also made of Zamak, each shoe 32 being guided in the lower rail 23 of the upper frame 16.

[0084] Preferably, the upper rail 22 and / or the lower rail 23 comprises a lip (not shown) provided with a brush seal (not shown) in order to reduce noise when opening and closing the shutter 7.

[0085] In addition, the leaves 26 of the shutter 7 may each comprise a covering blade 33 called a “wolf’s mouth” blade. The covering blades 33 partially overlap when the shutter 7 is closed (see [Fig.7]).

[0086] The shutter 7 may further comprise low locks positioned on the covering slats 33 and which prevent the leaves 26 from flapping in the wind, as well as preventing break-ins.

[0087] The shutter 7 may also comprise two pins (not shown), respectively top and bottom, for example made of Zamak, mounted for example by clipping or by “quarter turn” type fixing respectively on the upper rail 22 and on the lower rail 23. The leaves 26 may furthermore each comprise a battering blade, which here corresponds to the “wolf’s mouth” covering blade 33, which meet at the pin when the shutter 7 is closed.

[0088] The shutter 7 may also comprise a closing handle 37, for example made of electrogalvanized steel, mounted for rotation and translation on a first slider 38 which comprises one of the flap blades, and cooperating with a closing member 39 mounted for rotation and translation on a second slider 40 which comprises the other of the flap blades. The closing handle 37 makes it possible to lock the shutter 7 in the closed position but also to adjust the tension of the shutter 7 when it is closed.

[0089] The shutter 7 may also comprise a sealing joint, for example made of flexible PVC, mounted at the level of the first lateral edge 20 and / or the second lateral edge 21, preferably over the entire height of the upper obstruction part 5.

[0090] The lower obstruction part 6 will now be described in more detail.

[0091] The lower frame 17 of the lower obstruction part 6 is here a frame comprising four profiled elements 41, 42, 43 and 44, preferably made of aluminum, for example with a section of 33x26 mm (thickness 15 / 10ths), and which are here mechanically assembled for example using four brackets, for example of the pin type.

[0092] The lower obstruction portion 6 comprises a filler panel 45 mounted in the lower frame 17.

[0093] For example, the filling panel 45 is a glass panel (for example, a “44.2STADIP” type glazing).

[0094] According to another example, the filler panel 45 is a metal panel, such as an aluminum sheet.

[0095] The filling panel 45 can be assembled by gluing and screwing to the lower frame 17.

[0096] The filling panel 45 may be perforated, and include perforations 46, for example hexagonal in shape in the example illustrated. Such a filling panel 45 provides a sunshade function.

[0097] Furthermore, in particular when the filling panel 45 is made of sheet metal, it is possible to produce this sheet metal by a manufacturing process by punching or cutting which makes it possible to produce holes of various shapes in such a thin plate (for example, holes of round, half-moon, elliptical, cross, soap bubble, oval shape, etc.).

[0098] The lower obstruction part 6 comprises a first rolling member 47 and a second rolling member 47, respectively movable in translation in the first lateral profile 11 and the second lateral profile 12 of the pre-frame 4, and respectively mechanically connected in rotation to the lower profiled element 41 of the lower frame 17.

[0099] In the illustrated example, the above-mentioned first hinge 18 which rotatably connects the lower part of the upper frame 16 to the upper part of the lower frame 17 is made by an elongate element 53 with a U-shaped section. At each of the ends of the branches of the U-shape, the elongate element 53 comprises second beads 49. The lower rail 23 of the upper frame 16 comprises a first lower longitudinal groove 50, and the upper profiled element 42 of the lower frame 17 comprises a second upper longitudinal groove 51. The second beads 49 of the first hinge 18 are respectively housed in the first lower longitudinal groove 50 and in the second upper longitudinal groove 51, and thus form the first hinge 18.

[0100] The device 1 may further comprise a holding member configured to hold the device 1 in its sun visor configuration.

[0101] For example, the holding member is formed by a compressed gas cylinder 52, comprising a cylinder body 54 which is mechanically secured to the lower obstruction part 6, and a cylinder rod 55 (associated with a piston located in the cylinder body 54) which is mechanically secured to the pre-frame 4.

[0102] Preferably, the holding member comprises two jacks 52, arranged respectively at the level of the first lateral profile 11 and the second lateral profile 12.

[0103] The cylinder 52 is preferably of the “trunk cylinder” type, which usually allows the tailgate of a car to be opened and closed. Such a tailgate cylinder corresponds to a piston in which there is a compressed gas and a small volume of oil. When it is actuated, a progressive transfer of gas and oil takes place in the cylinder through the piston head which is perforated, allowing the piston to be moved in a damped movement.

[0104] Thus, such a holding member also forms a damping device making it possible to dampen oscillations when moving from the obstruction configuration to the sun visor configuration, and vice versa.

[0105] According to another embodiment of the holding member, the latter may be formed by one or more springs, for example traction springs, arranged so as to hold the device 1 in the sun visor configuration.

[0106] According to yet another embodiment of the holding member, the latter may be formed by a cable-pulley type mechanism, comprising a first cable and a second cable (not shown) extending respectively in the first lateral profile 11 and the second lateral profile 12, each of the cables being mechanically connected to the lower obstruction part 6, here on the one hand to the first rolling member 47, respectively second rolling member 47, and on the other hand to a counterweight which the holding member comprises.

[0107] The mass of the counterweight is selected such that the device 1 is maintained in the sunshade configuration, depending on the mass of the upper obstruction part 5 and the lower obstruction part 6, while ensuring that the device 1 can be manually moved into its obstruction configuration.

[0108] The device 1 may also be motorized and comprise an actuator configured to be able to move the upper obstruction part 5 and lower obstruction part 6 so as to allow the device to move from its obstruction configuration into its sun visor configuration, and vice versa.

[0109] For example, such an actuator may be an electric motor, preferably electrically powered by a solar panel (photovoltaic or other type) placed on the building equipped with the device 1.

[0110] For example, such an actuator may be connected by a data link to a control member equipped with communication means, for example wireless, and configured to receive actuator control instructions from, for example of a home automation control system.

[0112] - The opening is different from a window, for example the opening is a door or a French window;

[0113] - The upper obstruction part is similar to the lower obstruction part, and features an infill panel rather than a louver.

[0114] - The lower obstruction part is similar to the upper obstruction part, and features a louver rather than an infill panel.

[0115] - The vertical blades of the shutter can alternatively or completely also include perforations or any other type of opening other than ventilation slots;

[0116] - The vertical blades of the shutter are not openwork, that is to say they can be devoid of any opening;

[0117] - The vertical blades of the shutter are made of a different material from aluminum, for example steel;

[0118] - The shutter can be equipped with an internal security bar, for example made of a steel tube;

[0119] - The shutter can be opened in the sunshade configuration of the device.

[0120] It is recalled more generally that the invention is not limited to the examples described or illustrated.
