Description

Title of the invention: Removable, kit-form security system for a wall opening Technical field of the invention

[0001] The invention relates to the technical field of intrusion detection systems. It relates more particularly to a removable security system for a wall opening. Technological background

[0002] In the current landscape of building security, particularly residential security, window intrusion detection systems play a significant role. These systems are designed to protect homes and other buildings from unauthorized intrusions through vulnerable openings such as windows.

[0003] In this context, sophisticated and expensive technologies such as motion detectors, infrared sensors and audible alarms require a source of electrical power to operate, and their installation requires the services of a professional.

[0004] Other solutions, such as roller shutters or recessed security grilles, are common on the market. However, the first major drawback is that these systems are not designed to be removable. Once installed, they are generally fixed and cannot be easily taken down. This poses a considerable problem when occupants need to modify their security configuration, for example, during renovations or changes in lifestyle. This rigidity can also be problematic when they prevent access for emergency services, such as firefighters, who might need to enter the building in an emergency.

[0005] Another major drawback of these systems is their negative impact on the aesthetics of the house. Indeed, most window security systems are visually bulky and intrusive, which can ruin the aesthetic appeal of the window and the house in general. Furthermore, these devices can sometimes permanently block the view and the entry of natural light, thus degrading the quality of life inside the house. Objectives of the invention

[0006] The invention aims to provide a wall bay security system that can be easily mounted and dismounted by a single person.

[0007] The invention aims to provide such a security system in the form of a kit comprising all the parts necessary for the assembly of said security system.

[0008] The invention aims in particular to provide, in at least one embodiment, a system for securing a bay in a wall allowing it to be configured so as to be able to quickly and at least partially free the surface of the bay without requiring it to be completely dismantled. Description of the invention

[0009] To this end, the invention relates to a removable, kit-form security system for a bay window in a wall extending between a first space, referred to as the interior space, and a second space, referred to as the exterior space, comprising: - a frame suitable for mounting on the wall around said bay and comprising a first mechanical structure, called a guide structure, and a second mechanical structure, called a storage structure; - a plurality of barrier elements suitable for being positioned on said mechanical guidance and storage structures; - a clamping device for said plurality of barrier elements on said mechanical guiding structure;

[0010] characterized in that the security system is capable of switching between two configuration modes, called armed mode and disarmed mode, the switch from armed mode to disarmed mode being able to be carried out only from the interior space;

[0011] in said armed mode, said plurality of barrier elements, said guide structure and said clamping device are arranged according to an isostatic mechanical configuration inducing a fractionation of said bay into a plurality of domains, each of said domains having an area less than a predetermined threshold, said intrusion threshold;

[0012] in said disarmed mode, said plurality of barrier elements is arranged so that at least a portion of said wall opening, with an area greater than said intrusion threshold, is free of any barrier element.

[0013] It is then understood that, when said security system is configured in armed mode, it prevents access to said interior space, through the wall opening, by any person located in said exterior space by means of the storage of said plurality of barrier elements which induce a division of the opening into a plurality of domains all of an area less than said predetermined intrusion threshold.

[0014] Said predetermined intrusion threshold can, for example, be defined in relation to the measurements of a person, in particular an adult person.

[0015] By proceeding in this way, the invention proposes to provide a removable security system for a bay window in a wall offering increased flexibility and security.

[0016] According to this advantageous embodiment, the system includes a frame to be mounted on the wall around the wall opening to support the plurality of barrier elements and to stiffen the structure of the system when it is in armed mode configuration in order to block access to the interior space from the exterior space through the wall opening.

[0017] According to this advantageous embodiment, the chassis also includes a guide structure enabling the movement of the barrier elements to be guided when they move during the switch between the two configuration modes.

[0018] Advantageously, the chassis also includes a storage structure allowing at least some of the barrier elements to be stored.

[0019] These mechanical guide structures allow the plurality of barrier elements to be positioned so that all the barrier elements can be clamped together using a clamping device. One of the main advantages of this system is that it can switch between two configuration modes, called armed mode and disarmed mode, so that the switch from armed to disarmed mode can only be made from one side of the wall. This provides an additional level of security, as it prevents unauthorized access to the opening from the other side of the wall.

[0020] In the armed mode, the plurality of barrier elements, the guiding structure, and the clamping device are arranged in an isostatic mechanical configuration. This configuration results in the bay being divided into a plurality of domains, each of which has an area smaller than the intrusion threshold. By proceeding in this manner, the invention, according to this configuration, makes it possible to effectively secure the bay against intrusion from the outside, while allowing a certain flexibility in the barrier configuration. For example, the barrier elements can be arranged to create domains of different sizes, depending on the specific security requirements.

[0021] In disarmed mode, the plurality of barrier elements is arranged so as to free at least a portion of the wall opening, with an area greater than the intrusion threshold, from any barrier element. This allows the opening to be opened quickly and easily to permit access or viewing, while maintaining a certain level of security. For example, part of the opening can be left open to allow entry and exit, while the rest of the opening remains secured by the barrier elements. This offers great flexibility of use, while maintaining a high level of security.

[0022] In the context of the present invention, "isostatic structure" means a mechanical structure in which all degrees of freedom are eliminated, in particular the structure is immobile and exhibits high resistance to mechanical stresses.

[0023] In the context of the present invention, "bay" means an opening in a wall. This bay could, in particular, be fitted with a pane of glass and thus constitute a window or "bay window".

[0024] In the context of the present invention, the "diameter" of an object means the value of the greatest distance between any two points of said object.

[0025] In one embodiment of the invention, said guiding and storage structures are arranged on the same mechanical structure, called master structure.

[0026] According to this advantageous embodiment of the invention, the simultaneous arrangement of said guiding and storage structures on a single mechanical structure offers a significant advantage in terms of simplicity, design, and assembly efficiency. Indeed, by combining the two structures into one, the number of parts required for system assembly is reduced, thus simplifying the assembly process and reducing the time required for assembly and disassembly. Furthermore, this can also reduce the system's production cost, as fewer parts are needed. Thus, this unified design improves the robustness and stability of the security system, as there are fewer connection points that could potentially be weak points. In addition, it allows for a smoother transition between armed and disarmed modes, as the barrier elements can be more easily moved on a unified structure.

[0027] In one embodiment of the invention, said guiding and storage structures are rails.

[0028] According to this advantageous embodiment, the guide and storage structures have a geometry that constrains the movement of the barrier elements on the rail, allowing the user to easily control their movement.

[0029] This offers increased flexibility in the positioning of the barrier elements, allowing for more precise adaptation to the specific configuration of the wall opening. Furthermore, the use of rails facilitates the movement of the barrier elements between armed and disarmed modes, making the system easier to use and more efficient in terms of the transition time between the two modes. This feature improves the functionality and efficiency of the security system. In addition, the use of rails can also improve the system's robustness, as they provide solid support for the barrier elements, thus increasing the overall security of the system.

[0030] In one embodiment of the invention, the chassis includes fixing structures suitable for fixing said master structure to the wall.

[0031] According to this advantageous embodiment of the invention, the frame of the security system includes fixing structures suitable for attaching said frame to the wall. This offers a significant advantage with regard to the ease of installation of the security system and its structural stability. Indeed, these fixing structures allow for a solid and durable installation of the frame on the wall, thus ensuring greater resistance to break-in attempts or adverse environmental conditions. Furthermore, they offer greater flexibility in choosing the installation location, as they allow the frame to be fixed to different types of wall surfaces. Advantageously, this simplifies the installation process, since the fixing structures included in the frame eliminate the need for additional fixing hardware.

[0032] In one embodiment of the invention, the chassis further comprises a plurality of brackets forming with bolting elements said structures for fixing the chassis to the wall.

[0033] According to this advantageous embodiment of the invention, integrating brackets as fixing structures in a removable, kit-based wall-mounted window security system offers greater flexibility and ease of installation. These brackets allow for a solid and stable fixing of the frame to the wall, thus ensuring better resistance to break-in attempts or unauthorized removal. Furthermore, the use of brackets and bolts facilitates the positioning of the system while simplifying its installation and use.

[0034] Advantageously, said plurality of brackets includes in particular 4 brackets for fixing the frame of the security system to the wall.

[0035] In one embodiment of the invention, the brackets include a tab allowing the movement of at least one master structure to be constrained, along at least one spatial direction.

[0036] According to this advantageous embodiment of the invention, the tabs make it possible to constrain the undesired movements of the master structures, and consequently of the guiding and storage structures, which provides additional rigidity and stability to the securing system.

[0037] In one embodiment of the invention, the configuration of said armed mode arranges said plurality of barrier elements on said mechanical guiding structure.

[0038] According to this advantageous embodiment of the invention, the armed mode configuration arranges the plurality of barrier elements on the mechanical guide structure. This offers a significant advantage in terms of safety and flexibility. Indeed, by positioning the barrier elements on the guide structure during the In armed mode, this allows for a more efficient and precise distribution of barrier elements, thus enhancing the security of the wall opening. Furthermore, it facilitates switching between armed and disarmed modes, as the barrier elements are already positioned on the guide structure. This reduces the time and effort required to change modes and improves the functionality of the security system, optimizing both safety and ease of use.

[0039] In one embodiment of the invention, the configuration of said disarmed mode arranges at least a part of said plurality of barrier elements on said mechanical storage structure.

[0040] According to this advantageous embodiment of the invention, the removable, kit-based security system for a wall opening has an additional feature in its disarmed mode configuration. This configuration organizes at least some of the barrier elements on the mechanical storage structure. This arrangement offers a significant advantage in terms of space management and ease of use. When the system is disarmed, the barrier elements are not simply removed but are neatly stored on the storage structure. This frees up space while keeping the barrier elements readily accessible for quick system reactivation. The technical effect associated with this feature is therefore improved space utilization efficiency and increased ease of use of the security system.

[0041] In one embodiment of the invention, the clamping device for said plurality of barrier elements comprises at least one mechanical structure, called compression structure, rotatably mounted on the wall, capable of performing revolution movements around an axis, called arming axis, such that the switching from one configuration mode to the other configuration mode requires that said compression structure perform a revolution movement around said arming axis between an initial position and a final position.

[0042] According to this advantageous embodiment of the invention, the mechanical compression structure is capable of performing revolutions around the arming axis. This means that switching from one configuration mode to another requires the compression structure to perform a revolution between an initial and a final position. This offers a significant security advantage, as it makes the locking system more difficult to disarm without authorization. Indeed, the revolution required to switch from the armed to the disarmed mode can only be performed from one side of the wall, thus limiting the possibilities for unauthorized access.

[0043] In one embodiment of the invention, the system includes a locking mechanism capable of preventing the rotation of said mechanical compression structure around said axis.

[0044] According to this advantageous embodiment of the invention, the locking mechanism prevents the rotation of the mechanical compression structure, thereby preventing any unauthorized or accidental manipulation of the compression device. Indeed, by blocking the rotation of this element, the locking mechanism ensures that the isostatic mechanical configuration, which divides the opening into several areas with diameters smaller than a predetermined intrusion threshold, remains stable and unaltered. This enhances the security of the system in armed mode by preventing any unwanted movement of the barrier elements. Thus, the invention improves the robustness and reliability of the locking system, ensuring optimal protection of the wall opening against any intrusion or unauthorized access.

[0045] In one embodiment of the invention, the locking mechanism provides for a hole allowing a pin to lock said locking mechanism.

[0046] In one embodiment of the invention, the barrier elements are mounted on a wheeled device capable of rolling along said guide and storage structure.

[0047] According to this advantageous embodiment of the invention, the barrier elements are mounted on a wheeled device capable of rolling along the guide structure. This offers a significant advantage in terms of ease of use and flexibility. Indeed, the fact that the barrier elements are mounted on wheels allows for smooth and effortless movement along the guide structure. This not only facilitates the process of switching between armed and disarmed modes, but also allows for precise adjustment of the barrier elements' position according to specific security requirements. Thus, optimal maneuverability and adaptability of the security system can be ensured, enabling more efficient and practical use in various situations and wall opening configurations.

[0048] In one embodiment of the invention, the barrier elements are made of steel, in particular stainless steel.

[0049] According to this advantageous embodiment, the steel provides optimal resistance to enable the system to resist intrusion attempts.

[0050] Alternatively, said barrier elements may be produced in aluminum, titanium, bronze, brass, or any other resistant metal alloy. These materials, while being robust and durable, also offer resistance to weathering and corrosion, making them ideal for long-term security applications.

[0051] In one embodiment of the invention, the barrier elements comprise a first hollow structure, referred to as the external barrier structure, and a second structure, referred to as the internal barrier structure; said internal barrier structure being able to be contained within said external barrier structure.

[0052] In one embodiment of the invention, said internal barrier structure comprises a plurality of plates made of a material having a tensile strength greater than 250 MPa, in particular made of steel.

[0053] Advantageously, said plurality of plates has a rigidity greater than 270 MPa.

[0054] In one embodiment of the invention, the wall defines a non-zero curvature surface, in particular distinct from a plane, and the guide and storage structures and barrier elements are characterized in that they have non-zero curvature, in particular curved rails and bars following the geometry of the wall surface.

[0055] According to this advantageous embodiment of the invention, the security system makes it possible to secure a bay in a wall with irregular geometry, such as a bay on the surface of a dome. List of figures
