Description

Title of the invention: Protective assembly for a building opening, designed to receive a protective screen, for example a roller shutter curtain. Technical field of the invention

[0001] The present invention relates to the technical field of protection assemblies for a building bay, intended to receive a protective screen, for example a roller shutter curtain. State of the art

[0002] In the field of construction, it is quite common to equip building bays with a protective assembly including a protective screen, for example a roller shutter curtain.

[0003] To this end, these protective assemblies include a housing designed to receive brackets carrying a drive shaft for winding and operating the protective screen. These devices are essential for weather protection, thermal insulation, and safety.

[0004] However, current solutions have several limitations.

[0005] For example, current protective assemblies often require spacers to ensure correct alignment of the brackets within the box, which increases the complexity of the installation, implies alignment constraints and manufacturing cost.

[0006] The spacers fix the dimension between the brackets and the side wall of the enclosure, which limits the system's flexibility. This constraint can lead to difficulties when adjusting the components during installation, requiring precise measurements and custom manufacturing for each specific building bay configuration.

[0007] Moreover, the components of these systems, such as consoles and drive shafts, are often integrated in a fixed manner, making accessibility, dismantling and repairability of the assemblies difficult in the event of failure or maintenance.

[0008] Furthermore, current devices also suffer from alignment problems, particularly between the tulip and the guide rail, which can lead to malfunction of the roller shutter curtain, thus compromising the overall reliability. Limited visibility of the disassembly methods and the complexity of the interfaces further increase the difficulty of maintenance, often requiring specific tools for repairs. Presentation of the invention

[0009] In order to remedy the aforementioned drawback of the prior art, the present invention proposes a protection assembly for a building bay, intended to receive a protective screen, for example a roller shutter curtain.

[0010] The protection assembly includes:

[0011] - a chest comprising a set of walls including two side walls connecting four longitudinal walls, namely two front walls, an upper wall and a lower wall,

[0012] each of which walls comprise an inner face, together defining a usable volume,

[0013] which lower wall defines a descent slot, through which said protective screen is intended to pass,

[0014] - a drive shaft, for winding and operating said screen protection,

[0015] - two brackets, each assembled with one end of said shaft training.

[0016] According to the invention, said drive shaft and said two consoles form a protection sub-assembly.

[0017] And the two consoles and at least one of said inner faces are complementary, forming translational assembly means which allow assembly of said protection sub-assembly within said useful volume by a translational maneuver of said protection sub-assembly along a translational direction which is oriented perpendicular to said drive shaft (parallel to the side walls of the box).

[0018] The present invention thus presents several significant advantages compared to the prior art.

[0019] First of all, the width dimension of the consoles is advantageously constant, with a free variable of the protection sub-assembly, which ensures uniform alignment of the components and simplifies both the manufacture and the adaptation to the width dimension of the box.

[0020] Eliminating spacers is another major advantage. This not only reduces the number of components required but also simplifies the structure and lowers manufacturing costs. This simplification results in easier assembly, avoiding the complex adjustments often required with spacers. Furthermore, separating the components into sub-assemblies allows for easier maintenance by facilitating disassembly and reassembly, which significantly improves repairability and promotes an eco-design approach.

[0021] The reliability and disassembly / repairability of the assembly are also increased thanks to a modular design, allowing for quick and efficient intervention in case of failure, and thus improving the durability of the protection assembly.

[0022] Finally, the present invention allows several free variables, such as the spacing of the tulips or the width of the protective screen, which allows specific adjustments to optimize the operation and adaptability of the protection assembly to different building bay configurations.

[0023] In addition, the direct link between the consoles and the box limits the interfaces and promotes direct visibility of the dismantling means, thus facilitating the extraction of the shaft, the consoles, the operating elements (winch, motor, etc.) and possibly the apron.

[0024] Preferably, separating the tulip and the bracket also contributes to good alignment between the tulip and the guide rail, thus ensuring reliable operation of the curtain's descent within the guide rail. This contributes to the reliable operation of the curtain's descent within the guide rail.

[0025] This structure according to the invention also allows for a constant dimension between the bracket and the side of the box. The dimensional variable between the overall width of the box and the dimension between the jambs is addressed by a variable dimension of the drive shaft length relative to the width of the apron.

[0026] Other non-limiting and advantageous features of the product according to the invention, taken individually or in all technically possible combinations, are as follows:

[0027] - the length dimension of said protective subassembly, defined by the brackets, corresponds to the play in length of the usable volume, defined by the interior faces opposite the two lateral walls;

[0028] - each console comprises a front panel, assembled with one end of said drive shaft, and peripheral flaps, connected to said front wall; said peripheral flaps forming a first part of the translational assembly means and cooperating directly with an inner face of the longitudinal walls of said box forming a second part of the translational assembly means; preferably, each bracket comprises at least two opposing peripheral flaps, forming a first part of the translational assembly means and cooperating with two opposing longitudinal walls of said box, advantageously the upper and lower walls, forming a second part of the translational assembly means; preferably, the bracket comprises at least three peripheral flaps, each cooperating with one of the longitudinal walls; preferably, the front wall of a bracket comprises an outer face, coming into view of a side wall of the chest, and said peripheral shutters extend on the side of said outer face, to define a reservation;

[0029] - said protective assembly includes two tulips, for guiding the screen of protection through said descent slot and at the entrance of the slides, which tulips are independent with respect to said brackets and are movable in translation along said descent slot;

[0030] - the drive shaft cooperates with maneuvering means, for the maneuvering in rotation of said drive shaft, advantageously among electrical operating means and manual operating means; preferably, the manual operating means include axis return means, carried by said console, preferably by an external face, comprising a first interface cooperating with the drive shaft and a second interface receiving a removable floating square, and angle return means, carried by a side wall of the box, preferably by an external face, comprising a first interface cooperating with said removable floating square passing through said side wall of the box and a second interface cooperating with a crank.

[0031] The present invention also relates to joinery for building openings, comprising:

[0032] - a dormant, and

[0033] - a protective assembly according to the invention.

[0034] Of course, the various features, variants, and embodiments of the invention can be combined in various ways, provided they are not incompatible or mutually exclusive. Detailed description of the invention

[0035] In addition, various other features of the invention become apparent from the attached description made with reference to the drawings which illustrate non-limiting embodiments of the invention and where:

[0041] [Fig.6] is a schematic view, and according to a horizontal cutting plane, illustrating the axis transfer means and the angle transfer means.

[0042] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.

[0043] The present invention thus relates to a protection assembly 10 for a building bay (not shown), intended to receive a protective screen.

[0044] The term "building opening" advantageously refers to an opening made in a wall of a building, intended to receive a closing element such as a window, a door, or a protective screen like a roller shutter. This opening generally comprises a fixed frame D (fixed frame), onto which the movable closing elements may be hinged.

[0045] As further developed, "protective screen" advantageously means a mobile structure intended to protect a building opening such as a bay window.

[0046] This protective screen can be a roller shutter curtain composed of slats hinged together, allowing them to be raised or lowered to open or close the opening. The roller shutter curtain thus provides protection against the elements and intrusions, and can also contribute to the thermal and acoustic insulation of the building.

[0047] Generally, such a protective screen may also consist of a mosquito net or a veil (to adjust the light entering the building).

[0048] The protection assembly 10 comprises:

[0049] - a chest 20 comprising a set of walls 21,

[0050] - a drive shaft 30, for winding and operating the screen protection 40 (shown schematically in [Fig.3]),

[0051] - two brackets 50, each assembled with one end of the shaft 30 training sessions.

[0052] According to the invention, the drive shaft 30 and the two brackets 50 form a protective sub-assembly 15. Chest

[0053] The chest 20 comprising a set of walls 21 including two lateral walls 211 connecting four longitudinal walls:

[0054] - two front walls 212 (only one of the front walls is present here),

[0055] - an upper wall 213, and

[0056] - a lower wall 214, also called the underside (visible on the [Fig.4]).

[0057] The walls 21 each have an inner face, together defining a useful volume V, namely:

[0058] - the side walls 211 each have an inner face 2111, opposite one from the other,

[0059] - the front walls 212 each have an inner face 2121, opposite one from the other,

[0060] - the upper wall 213 has an inner face 2131, oriented towards the wall lower 214, and

[0061] - a lower wall 214 has an inner face 2141, oriented towards the wall superior 213.

[0062] The lower wall 214 defines a descent slot F, through which said protective screen 40 is intended to travel towards tracks C.

[0063] This descent slot F is advantageously delimited, longitudinally, between this lower wall 214 and a first front wall 212a.

[0064] And a second front wall 212b, schematically illustrated in [Fig.2], is advantageously removable to form an access hatch. Protection subset

[0065] As mentioned previously, the drive shaft 30 and the two consoles 50 form a protection subset 15.

[0066] Such a protection sub-assembly 15 advantageously constitutes a functional module of the protection assembly 10, intended to receive a protective screen (for example a roller shutter curtain), which is intended to cooperate with the box 20.

[0067] Thanks to this modular design, the protection sub-assembly 15 offers improved disassembly and repairability. This facilitates assembly, as well as quick and effective intervention in the event of a failure, thus improving the durability and reliability of the protection assembly 15.

[0068] According to the invention, the two brackets 50 and at least one of the inner faces 2111, 2121, 2131, 2141 of the box 20 are complementary, forming translational assembly means 60 which allow the assembly of said protection sub-assembly 15 within the useful volume V by a translational movement of this protection sub-assembly 15 along a translational direction T which is oriented perpendicular to said drive shaft 30 (parallel to the side walls 211 of the box 20).

[0069] For this purpose, preferably, the length dimension of said protective sub-assembly 15, defined by the brackets 50, corresponds to the length dimension of the useful volume V (defined by the inner faces 2111 opposite the two side walls 211).

[0070] More specifically, the drive shaft 30 has two ends 301, defining a longitudinal axis 30'.

[0071] And these ends 301 are each secured with one of the brackets 50.

[0072] Furthermore, each console 50 includes:

[0073] - a front wall 51, assembled with an end 301 of the drive shaft 30, and

[0074] - peripheral flaps 52 (also called "returns"), connected to the front wall 51.

[0075] The front wall 51 extends advantageously perpendicularly with respect to the longitudinal axis 30'.

[0076] This front wall 51 extends opposite an inner face 2111 opposite a lateral wall 211.

[0077] The front wall 51 advantageously comprises two opposing faces:

[0078] - an inner face 511, extending opposite the drive shaft 30, and

[0079] - an outer face 512, extending opposite the inner face 2111 opposite the side wall 211.

[0080] Preferably, the front wall 51 has a through hole 513 which is secured to one end 301 of the drive shaft 30.

[0081] Furthermore, the peripheral flaps 52 form a first part 61 of the translational assembly means 60. These peripheral flaps 52 cooperate, advantageously directly, with an inner face 2111, 2121, 2131, 2141 of the longitudinal walls 212, 213, 214 of the box 20 forming a second part 62 of the translational assembly means 60.

[0082] In other words, the shapes of the peripheral flaps 52 and the longitudinal walls 212, 213, 214 are designed to fit together perfectly, thus ensuring an efficient and stable translational assembly.

[0083] The peripheral flaps 52 and the longitudinal walls 212, 213, 214 can cooperate directly. They can also cooperate via profiles, forming rails, attached in particular to the longitudinal walls 212, 213, 214.

[0084] This design allows precise cooperation between the different parts, guaranteeing the structural integrity and optimal functionality of the protection assembly for the building bay.

[0085] Generally, each console 50 advantageously comprises at least two opposing peripheral flaps 52, forming the first part 61 of the translational assembly means 60.

[0086] These peripheral flaps 52 cooperate with two opposing longitudinal walls 212, 213, 214 of the box 20, which then form the second part 62 of the translational assembly means 60.

[0087] Preferably, the peripheral flaps 52 comprise:

[0088] - an upper peripheral flap 523 cooperating with the upper wall 213, and

[0089] - a lower peripheral flap 524 cooperating with the lower wall 214.

[0090] In other words, during translational positioning, the upper peripheral flap 523 slides along the depth of the upper wall 213, and the lower peripheral flap 524 slides along the depth of the lower wall 214.

[0091] Preferably, the console 50 includes at least three peripheral flaps 52 which each cooperate with one of the longitudinal walls 212, 213, 214, advantageously the upper wall 213, the lower wall 214 and the first front wall 212a defining the descent slot F.

[0092] In this case, the peripheral flaps 52 advantageously include a front peripheral flap 522 cooperating with the first front wall 212a to define the end-of-travel position in translation.

[0093] This front peripheral flap 522 can also cooperate with a stop element carried by one of the walls of the box 20.

[0094] In this case, the blocking in translation in the opposite direction can be obtained by an insulator which serves as an interface between the brackets 50 and the inspection hatch 212, or by any other blocking element in translation.

[0095] In general, the consoles 50 may optionally include shapes (slots, orifices, etc.) adapted to their gripping and manipulation in translation (in particular in extraction).

[0096] In this case, the peripheral flaps 52 extend from the side of the outer face 512 of the front wall 51, to define a reservation 515 (opening towards the inner face 2111 opposite the side wall 211).

[0097] These peripheral flaps 52 here include free peripheral edges 521 which can bear against the inner face 2111 opposite the side wall 211. Alternatively, an insulating element (advantageously of fixed width) can be introduced between the front wall 51 and the inner face 2111 opposite the side wall 211.

[0098] The protective sub-assembly defines a fixed dimension between the front wall 51 and the inner face 2111 opposite the side wall 211.

[0099] In other words, the drive shaft 30 has a variable length; similarly, the protective screen 40 has a variable width, advantageously depending on the width dimension between the slides C. At the same time, the front wall 51 and the inner face 2111 opposite the side wall 211 together define a fixed dimension (or a constant dimension). Tulips

[0100] In general, the protection assembly 10 includes two tulips 70, for guiding the protective screen 40 through the descent slot F and into the slide entrance C.

[0101] Advantageously, the tulips 70 are independent of the brackets 50. They are also movable in translation along the descent slot F. These tulips 70 are intended to be indexed in the slides C.

[0102] The independence of the tulips 70 from the brackets 50 allows greater flexibility and better adaptability when installing and adjusting the protective assembly.

[0103] This configuration facilitates maintenance and replacement of individual components without disrupting the entire system.

[0104] In addition, the translational mobility of the tulips 70 along the descent slot F ensures precise and stable guidance of the protective screen 40, thus improving the performance and durability of the assembly.

[0105] This feature also makes it possible to compensate for any misalignments or dimensional variations, ensuring reliable and smooth operation of the protective screen. Means of maneuver

[0106] Generally and advantageously, the drive shaft 30 cooperates with maneuvering means 80 (illustrated schematically on [Fig.3]), for the rotational maneuvering of the drive shaft 30.

[0107] These means of maneuver 80 are advantageously chosen from among:

[0108] - electrical operating means,

[0109] - means of manual operation.

[0110] The electrical operating means include, for example, an integrated electric motor which is directly integrated into the drive shaft 30 or into the housing 20. This motor can be controlled by a wall switch, a remote control, or a home automation system.

[0111] The means of manual operation include, for example, a hand crank, fixed to the drive shaft, allowing it to be turned manually to raise or lower the protective screen.

[0112] According to one embodiment illustrated in Figures 4 to 6, the manual operating means 80 comprise:

[0113] - means for referring axis 81 (figures 4 and 6), carried by the bracket 50, of preferably by an outer face 512 of the front wall 51, and

[0114] - angle transfer means 82 (figures 5 and 6), supported by a side wall 211 of the trunk 20, preferably from an external face 2111.

[0115] This embodiment is particularly interesting in the context of a renovation with a side winch exit.

[0116] The means for referring axis 81 are housed here in the reservation 515.

[0117] The means for transferring axis 81 advantageously comprise:

[0118] - a first interface 811 cooperating with the drive tree 30 and

[0119] - a second interface 812 receiving an extractable floating square 813.

[0120] The first interface 811 and the second interface 812 are advantageously parallel and at a distance (or remote).

[0121] In this case, the axis of rotation of the first interface 811 and the second interface 812 advantageously extends parallel to the longitudinal axis 30'.

[0122] The angle transfer means 82 advantageously comprise:

[0123] - a first interface 821 cooperating with the extractable floating square 813 passing through the side wall of the trunk 20, and

[0124] - a second interface 822 cooperating with a crank M.

[0125] In this case, the axis of rotation of the first interface 821 advantageously extends parallel to the longitudinal axis 30'; the axis of rotation of the second interface 822 advantageously extends perpendicularly to the longitudinal axis 30'. Implementation

[0126] To implement the present invention, the following steps are advantageously carried out:

[0127] - Preparation of the protection subassembly

[0128] First, the drive shaft 30 and the two brackets 50 are assembled to form the protection sub-assembly 15.

[0129] The brackets 50 are fixed to the ends of the drive shaft 30, providing support and allowing rotation of the shaft.

[0130] Preferably, the operating means 80 (for example electric or manual) are attached to the protection sub-assembly 15, before the protection sub-assembly 15 is mounted in the box.

[0131] Similarly, the aforementioned insulating elements (coming between the front wall 51 and the inner face 2111 opposite the side wall 211) can equip the brackets 50, before the assembly of the sub-assembly 15.

[0132] - Mounting the protective sub-assembly in the trunk

[0133] The protective sub-assembly 15 is inserted inside the box 20.

[0134] This assembly of the protection sub-assembly 15, within the useful volume V, is obtained by a translational maneuver of this protection sub-assembly 15 along the translational direction T which is oriented perpendicular to said drive shaft 30 (parallel to the side walls 211 of the box 20).

[0135] - Installation of the guide tulips

[0136] The tulips 70 can be fixed independently of the brackets 50.

[0137] These tulips 70 are advantageously indexed with respect to the side walls 211 of the chest 20, in a nominal position.

[0138] The protective screen can be wrapped around the drive shaft 30, before or after the mounting of the protective sub-assembly 15 in the box 20.

[0139] - Fixing the box to the frame:

[0140] Once the protective sub-assembly is mounted in the box, the latter can be fixed to the frame D.

[0141] The tulips 70, which move in translation along the descent slot F, guide the protective screen during its movement. They can be aligned with the descent slot and the guides C.

[0142] - Connection of maneuvering means

[0143] The operating means 80 are connected to the drive shaft. These means can be electric or manual.

[0144] For an electric means, the motor can be connected to a power source as well as to a switch or remote control. For a manual means, the crank can be connected to the drive shaft.

[0145] Of course, various other modifications can be made to the invention within the scope of the annexed claims.
