Description
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 openings with a protective set including a protective screen, for example a roller shutter curtain.
[0003] To achieve this, these protective assemblies include a housing designed to accommodate brackets that support a drive shaft for rolling up 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 proper alignment of the brackets within the case, which increases installation complexity, involves 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 components during installation, requiring precise measurements and custom manufacturing for each specific building bay configuration.
[0007] Furthermore, the components of these systems, such as consoles and drive shafts, are often permanently integrated, making it difficult to access, dismantle, and repair the assemblies in the event of failure or maintenance.
[0008] Furthermore, current systems also suffer from alignment problems, particularly between the roller tube and the guide rail, which can lead to malfunctions in 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 specialized 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 kit includes: a box comprising a set of walls including two side walls connecting four longitudinal walls, namely two front walls, a top wall and a bottom wall, each of which walls has an inner face, together defining a usable volume, which bottom wall defines a descent slot, through which said protective screen is intended to pass, a drive shaft, for winding and operating said protective screen, two brackets, each assembled with one of the ends of said drive shaft.
[0011] According to the invention, said drive shaft and said two consoles form a protective sub-assembly.
[0012] And the two consoles and at least one of the said inner faces are complementary, forming means of translational assembly which permit the assembly of said protective sub-assembly within said useful volume by a translational maneuver of said protective sub-assembly in a translational direction which is oriented perpendicular to said drive shaft (parallel to the side walls of the box).
[0013] The present invention thus offers several significant advantages over the prior art.
[0014] Firstly, 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 manufacturing and the adaptation to the width dimension of the trunk.
[0015] The elimination of 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 necessary with spacers. Furthermore, separating the components into sub-assemblies allows for easier maintenance by facilitating the disassembly and reassembly of parts, which significantly improves repairability and promotes an eco-design approach.
[0016] 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.
[0017] 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.
[0018] In addition, the direct link between the consoles and the trunk limits the interfaces and promotes direct visibility of the means of dismantling, thus facilitating the extraction of the shaft, the consoles, the operating elements (winch, motor, etc.) and possibly the apron.
[0019] Preferably, separating the tulip-shaped bracket from the console also contributes to proper 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.
[0020] 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 door panel.
[0021] Other non-limiting and advantageous characteristics of the product according to the invention, taken individually or in all technically possible combinations, are as follows: The length dimension of said protective sub-assembly, defined by the brackets, corresponds to the length dimension of the usable volume, defined by the inner faces opposite the two side walls; each bracket comprises a front surface, assembled with one end of said drive shaft, peripheral surfaces, connected to said front surface, said peripheral surfaces 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; advantageously, each bracket comprises at least two opposing peripheral surfaces, forming a first part of the translational assembly means and cooperating with two opposing longitudinal walls of said box, advantageously the upper wall and the lower wall, forming a second part of the translational assembly means;Each console comprises a front wall, 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 console 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 wall and the lower wall, forming a second part of the translational assembly means; preferably again, the console comprises at least three peripheral flaps, each cooperating with one of the longitudinal walls;Preferably, the front wall of a console comprises an outer face, opposite a side wall of the box, and said peripheral shutters extend on the side of said outer face, to define a recess; said protective assembly comprises two tulips, for guiding the protective screen through said descent slot and into the slides, which tulips are independent of said consoles and are movable in translation along said descent slot; the drive shaft cooperates with operating means, for the rotational operation of said drive shaft, advantageously among electrical operating means and manual operating means; preferably, the manual operating means comprise return means;
[0022] of axis, carried by said console, preferably by an external face, comprising a first interface cooperating with the drive shaft and a second interface receiving an extractable floating square, and angle transfer means, carried by a side wall of the box, preferably by an external face, comprising a first interface cooperating with said extractable floating square passing through said side wall of box and a second interface cooperating with a crank.
[0023] The present invention also relates to joinery for building openings, comprising: a dormant, and a protective assembly according to the invention.
[0024] Of course, the different features, variants and embodiments of the invention can be combined with each other in various ways as long as they are not incompatible or mutually exclusive. Detailed description of the invention
[0025] Furthermore, 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: [ Fig. 1 ] is a general and perspective view of a protective assembly according to the invention, in which the protective sub-assembly is extracted relative to the case; [ Fig. 2 ] is a general and perspective view of the protection system according to the figure 1 , in which the protective subset is housed in the safe; [ Fig. 3 ] is a schematic section of the protection assembly according to the invention, along a horizontal cutting plane passing through its drive shaft; [ Fig. 4 ] is a schematic and perspective view of the axis transfer means, supported by the console, for the manual operation of the drive shaft; [ Fig. 5] is a schematic and perspective view of the angle transfer means, supported by a side wall of the chest and intended to cooperate with a crank; [ Fig. 6 ] is a schematic view, and according to a horizontal cutting plane, illustrating the means of axis transfer and the means of angle transfer.
[0026] It should be noted that, in these figures, the structural and / or functional elements common to the different variants may have the same references.
[0027] The present invention thus relates to a protection assembly 10 for a building bay (not shown), intended to receive a protective screen.
[0028] The term "building opening" is generally understood to mean an opening in a building wall, designed to receive a closing element such as a window, door, or protective screen like a roller shutter. This opening typically includes a fixed frame (D), onto which the movable closing elements may be hinged.
[0029] As further developed, the term "protective screen" advantageously refers to a mobile structure designed to protect a building opening such as a bay window.
[0030] This protective screen can be a roller shutter curtain made up of hinged slats that can 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 building's thermal and acoustic insulation.
[0031] In general, such a protective screen can still consist of a mosquito net or a veil (to adjust the light entering the building).
[0032] The protection set 10 includes: a box 20 comprising a set of walls 21, a drive shaft 30, for winding and operating the protective screen 40 (shown schematically on the figure 3 ), two consoles 50, each assembled with one end of the drive shaft 30.
[0033] According to the invention, the drive shaft 30 and the two consoles 50 form a protective sub-assembly 15. Chest
[0034] The chest 20 comprising a set of walls 21 including two lateral walls 211 connecting four longitudinal walls: two front walls 212 (only one of the front walls is present here), an upper wall 213, and a lower wall 214, also called the underside (visible on the figure 4 ).
[0035] Each wall 21 has an inner face, together defining a usable volume V, namely: the side walls 211 each have an inner face 2111, opposite each other, the front walls 212 each have an inner face 2121, opposite each other, the upper wall 213 has an inner face 2131, oriented towards the lower wall 214, and a lower wall 214 has an inner face 2141, oriented towards the upper wall 213.
[0036] The lower wall 214 defines a descent slot F, through which said protective screen 40 is intended to travel towards tracks C.
[0037] This descent slot F is advantageously delimited, longitudinally, between this lower wall 214 and a first frontal wall 212a.
[0038] And a second frontal wall 212b, schematically illustrated on the figure 2 , is advantageously demountable to form an access hatch. Protection subset
[0039] As mentioned previously, the drive shaft 30 and the two consoles 50 form a protection subset 15.
[0040] Such a protection subset 15 advantageously constitutes a functional module of the protection set 10, intended to receive a protective screen (for example a roller shutter curtain), which is intended to cooperate with the box 20.
[0041] Thanks to its 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.
[0042] 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 said protection sub-assembly 15 to be mounted 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).
[0043] 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).
[0044] More specifically, the drive shaft 30 has two ends 301, defining a longitudinal axis 30'.
[0045] And these ends 301 are each secured to one of the consoles 50. Furthermore, each console 50 comprises: a front surface 51, assembled with an end 301 of said drive shaft 30, peripheral surfaces 52, connected to said front surface 51, said peripheral surfaces 52 forming a first part 61 of the translational assembly means 60 and cooperating directly with an inner face 2121, 2131, 2141 of the longitudinal walls 212, 213, 214 of said chest 20 forming a second part 62 of the translational assembly means 60.
[0046] Preferably, each console 50 comprises at least two opposing peripheral surfaces 52, forming a first part 61 of the translational assembly means 60 and cooperating with two opposing longitudinal walls 212, 213, 214 of said chest 20, advantageously the upper wall 213 and the lower wall 214, forming a second part 62 of the translational assembly means 60.
[0047] According to one embodiment, each console 50 comprises: a front wall 51, advantageously forming said front surface 51, assembled with an end 301 of the drive shaft 30, and peripheral flaps 52 (also called "returns"), advantageously forming the peripheral surfaces 52, connected to the front wall 51.
[0048] The front wall 51 extends advantageously perpendicularly with respect to the longitudinal axis 30'.
[0049] This front wall 51 extends opposite an inner face 2111 opposite a lateral wall 211.
[0050] The front wall 51 advantageously comprises two opposing faces: an inner face 511, extending opposite the drive shaft 30, and an outer face 512, extending opposite the inner face 2111 opposite the side wall 211.
[0051] Preferably, the front wall 51 has a through hole 513 which is secured to one end 301 of the drive shaft 30.
[0052] 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.
[0053] 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.
[0054] The peripheral shutters 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.
[0055] This design allows for precise cooperation between the different parts, ensuring the structural integrity and optimal functionality of the entire protection system for the building bay.
[0056] In general, each console 50 advantageously comprises at least two opposing peripheral flaps 52, forming the first part 61 of the translational assembly means 60.
[0057] 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.
[0058] Preferably, the peripheral shutters 52 include: an upper peripheral flap 523 cooperating with the upper wall 213, and a lower peripheral flap 524 cooperating with the lower wall 214.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] This front peripheral flap 522 can also cooperate with a stop element carried by one of the walls of the box 20.
[0063] In this case, blocking in reverse translation can be achieved 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.
[0064] In general, the 50 consoles may include shapes (slots, holes, etc.) adapted to their gripping and manipulation in translation (in particular in extraction).
[0065] 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).
[0066] These peripheral shutters 52 here have free peripheral edges 521, advantageously forming an outer surface 521, which can rest on 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.
[0067] The protective sub-assembly defines a fixed dimension between the front wall 51 and the inner face 2111 opposite the side wall 211.
[0068] 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
[0069] 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.
[0070] 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.
[0071] The independence of the tulips 70 from the brackets 50 allows greater flexibility and better adaptability when installing and adjusting the entire protection assembly.
[0072] This configuration facilitates maintenance and replacement of individual components without disrupting the entire system.
[0073] Furthermore, 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.
[0074] 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
[0075] In general and advantageously, the drive shaft 30 cooperates with maneuvering means 80 (illustrated schematically on the figure 3 ), for the rotational operation of the drive shaft 30.
[0076] These maneuvering means 80 are advantageously chosen from among: means of electric operation, means of manual operation.
[0077] The means of electric operation include, for example, an integrated electric motor which is directly integrated into the drive shaft 30 or into the casing 20. This motor can be controlled by a wall switch, a remote control, or a home automation system.
[0078] Manual means of operation include, for example, a hand crank, attached to the drive shaft, allowing it to be turned manually to raise or lower the protective screen.
[0079] According to a form of realization illustrated on the figures 4 to 6 The means of manual operation 80 include: axis 81 transfer means ( figures 4 And 6 ), supported by the bracket 50, preferably by an external face 512 of the front wall 51, and angle transfer means 82 ( Figures 5 And 6 ), carried by a side wall 211 of the chest 20, preferably by an outer face 2111.
[0080] This type of construction is particularly interesting in the context of a renovation with a side winch exit.
[0081] The means of redirecting axis 81 are housed here in the reservation 515.
[0082] The means of redirecting axis 81 advantageously include: a first interface 811 cooperating with the drive shaft 30 and a second interface 812 receiving an extractable floating square 813.
[0083] The first interface 811 and the second interface 812 are advantageously parallel and at a distance (or remote).
[0084] In this case, the axis of rotation of the first interface 811 and the second interface 812 extends advantageously parallel to the longitudinal axis 30'.
[0085] The angle transfer means 82 advantageously include: a first interface 821 cooperating with the removable floating square 813 passing through the side wall of the trunk 20, and a second interface 822 cooperating with a crank M.
[0086] 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
[0087] To implement the present invention, the following steps are advantageously carried out: - Preparation of the protection sub-assembly
[0088] First, the drive shaft 30 and the two brackets 50 are assembled to form the protection sub-assembly 15.
[0089] The brackets 50 are fixed to the ends of the drive shaft 30, providing support and allowing rotation of the shaft.
[0090] Preferably, the means of operation 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.
[0091] 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. - Mounting the protective sub-assembly in the trunk
[0092] The protective sub-assembly 15 is inserted inside the box 20.
[0093] 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). - Installation of the guide tulips
[0094] The tulips 70 can be fixed independently of the brackets 50.
[0095] These tulips 70 are advantageously indexed relative to the side walls 211 of the chest 20, in a nominal position.
[0096] 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. - Fixing the box to the frame:
[0097] Once the protective sub-assembly is mounted in the box, the latter can be fixed to the frame D.
[0098] The tulip-shaped guides 70, which move along the descent slot F, guide the protective screen during its movement. They can be aligned with the descent slot and the tracks C. - Connection of maneuvering means
[0099] The 80 operating means are connected to the drive shaft. These means can be electric or manual.
[0100] For an electric motor, the motor can be connected to a power source as well as a switch or remote control. For a manual motor, the crank can be connected to the drive shaft.
[0101] Of course, various other modifications can be made to the invention within the scope of the attached claims.
