CENTRALIZED SECURITY CLOSURE
The invention relates to a principle of security closure for private dwellings or dwellings of collective buildings.

 Anti-intrusion security in such premises is generally ensured by an alarm system.

 Such systems do not generally know how to reconcile security and comfort for the occupant. Indeed, for many years, the problem of the anti-intrusion alarm was that of the protection of a carefully closed room, by an owner most often absent at the time of the attempted break-in.

 However, it frequently happens nowadays that these attempts are carried out despite the presence of the occupant, and sometimes completely without his knowledge.

This development is due to the appearance of new forms of crime, little concerned with risks, and to an understandable desire to open up dwellings to the outside, combining architectural style and lifestyle, by means of large picture windows.

 Alarm systems are very effective in detecting and alerting when an individual enters a protected area. Such an area is protected either by external detection means, or by a closed enclosure provided with perimeter sensors, or by internal detection means, or finally by a combination of these three elements.

 The interior means are generally put out of service by the occupant when he is present, at least in his normal development zone. The experience of several false alarms that he will have himself

<Desc / Clms Page number 2>

 provoked in general incites the occupier to extend the zone of invalidation of the interior means, which takes away from the effectiveness of the protection.

 The enclosure is generally open, at least during the day, so as to allow natural ventilation, visual communication towards the street, garden or relaxation areas. Under these conditions the second level of protection falls.

 For an owner who favors this opening to the outside, there would therefore only be peripheral detection in order to satisfy the comfort of the members of his family present in the house while ensuring their safety.

 But it is then necessary that this detection is designed to immediately trigger alarms and sirens as soon as a movement appears on the periphery, in order to gain in deterrence what the protection has lost due to the partial or total opening of the enclosure.

 This again results in sufficient false alarms caused by the passage of animals, the arrival of neighbors, repairers, delivery people or direct sellers, so that this system is quickly abandoned.

 The object of the invention is to provide a remedy to these malfunctions, by proposing a solution which makes it possible to reconcile the protection of property and the comfort or serenity of the occupants of a room.

 The invention also makes it possible to leave a room partially open in the absence of its owners, and / or to simulate their presence. It also allows you to lock a door or a bay that is closed, but not locked.

<Desc / Clms Page number 3>

 The invention is based on the combination of peripheral sensors, in particular volumetric, and a motorized control device for closing elements, such as windows, doors or shutters.

 Numerous patents describe security systems associating presence or movement detection sensors and the control of actuators moving a closure element.

 These patents relate in particular to the protection of persons, to avoid, for example, that an automatic door or a shutter injure a user in his closing movement.

 They also describe means causing the door to open when a customer or a user approaches it in the case of commercial or public premises.

 These patents all associate security with obstacle detection during a closing operation, and in this case introduce a function either of stopping or of reopening.

 The US patent. 4,563,625 is representative of this concern for protection. It also gives the possibility of adjusting the opening position of the door. It does not provide a semi-closed position, allowing the only passage of air.

 Unconventionally, the US patent. 4. 360.801 describes the association of a garage door actuator with a carbon monoxide sensor, so as to cause the opening in the event that the gas rate exceeds a safety threshold. It does not provide for a partially closed position.

 The US patent. 5.003. 290 describes a system integrating the access control and anti-intrusion alarm functions. This system allows the electrical opening or closing of one or more latches, which is close to the invention, but it does not introduce a scenario of partial closing of a closing element.

 The US patent. 5920. 270 describes the problem of the anxiety of alarm users, or the reluctance of owners to install such devices, due to the complexity of the procedures for arming or disabling the alarm. It does not provide for several protection scenarios.

 Although very complete in the field of arming and disarming of zones under alarms, although providing for interior or perimeter detection, although providing for gradual action on actuators (such as, for example, sirens, used to very low level as an acknowledgment signal), patent US4,918. 717 does not think of including the operation of the actuators of certain closing elements in its safety device.

 The US patent. 4. 755.792 describes a combined safety and control system, in which a carrier current transmission is used between sensors and actuators. These actuators are lamps or household appliances or alarm sirens. The system provides three main modes of operation: an instant armed mode, a delayed armed mode and a disarmed mode.

 Although not taking into account the closure elements used in the invention, this state of the art is, in its concept, close to the latter insofar as it provides for several reaction scenarios.

<Desc / Clms Page number 5>

 The delayed armed mode corresponds to the non-instantaneous triggering of the alarm after detection to allow the legitimate occupant of the room, if it is he who triggered the detection, to invalidate the alarm before actuation of the actuators.

 The invention proposes to associate at least one electrically actuable mobile closure system, such as a door, roller shutter, window, etc. with a presence or displacement sensor normally placed on the periphery of the zone to be protected, and with a programming and control device, the program of which comprises at least one mode of delayed action and means for switching to this mode of delayed action, characterized in that, once placed in the mode of delayed action the programming device and command only issues a complete closing order when the presence or movement sensor is activated.

 Other characteristics and advantages of the invention will emerge from the description which follows with reference to the appended drawings, which are given only by way of nonlimiting examples.

 Figure 1 shows a window with a shutter controlled by the device of the invention.

 FIG. 2 represents a sliding window controlled by the device of the invention.

 FIG. 3 thus details a form of software execution in the case where several closing elements cooperate in the security and monitoring functions.

 FIG. 4 illustrates a variant of software execution.

<Desc / Clms Page number 6>

 A first example to better understand the invention is that shown in Figure 1 of a window (1) provided with a roller shutter (2) movable up or down thanks to an actuator (3) electrically controlled. Through a radio or wire link, the actuator receives its orders from a control device (5), which can contain several management programs, one of these programs being, for example, activated by a radio remote control (6) playing the role of security key. These management programs can be either completely defined in advance by the manufacturer of the device, or configurable by the user as described, for example, in US patents. 4. 914.732 or 4.670. 747, and without difficulty for those skilled in the art accustomed to user interface functions in a programmed micro system.

 The control device (5) will, of course, recognize a closing order issued by the key (6) and activate the motor (3) accordingly.

 However, the assembly is designed so that the key (6) can issue at least one particular order, here called surveillance.

 Monitoring consists of keeping most of the openings in a maximum ventilation or vision position, these positions being defined as a function of rapid closure if the need arises.

 For example, on receipt of a monitoring instruction, the device (5) will give the actuator (3) the order to close the shutter to the defined position (7). In this position, the flap is, for example, 20 cm from its closed position. If the window is open, good ventilation is ensured.

<Desc / Clms Page number 7>

 If it is a shutter provided with openings, the position (7) can be the low position. In this position, the view is ensured from the inside thanks to the openings of the blades, which also allow ventilation.

 In the event of detection of peripheral presence, by the sensor (4), the device (5) gives the order to close the shutter completely, but without triggering the alarm actuators. The information from the sensor (4) can advantageously also be transmitted by the device (5) to the key (6) in order to discreetly warn the wearer of an active detection. As is known, the device (5) can, for example, on a screen, indicate the location of the detection.

 Thus, unlike the devices of the prior art, the deterrence offered by a closed enclosure becomes applicable to a dwelling or a room as open as possible.

 It is clear that, once placed in the surveillance mode and after detection of peripheral presence, the device (5) will interpret as a real attempt to break in any discomfort noted in the downward movement of the flap, along its course ( 8) between the monitoring rest position (7) and the fully closed position, if this descent was caused by detection on the sensor (4). The detection will then be passed on to the alarm actuators (siren, etc.).

 The same concept can be applied to windows as well, such as motorized sliding windows.

 FIG. 2 gives an exemplary embodiment, on a sliding opening (11) with a movable leaf. We find the same elements as before, namely, a remote control (16), a device for

<Desc / Clms Page number 8>

 control (15), a sensor 1 (4), an actuator (13), a defined monitoring rest position (17).

 As a precaution, when switching to monitoring mode, the sliding window will be positioned by the device (15) in a semi-closed position (17), guaranteeing good ventilation but for which the passage is insufficient for an intrusion. The stroke (18) is therefore reduced accordingly.

 In the case of a tilt-and-turn window, the open position is, in fact, an inclined position of one of the opening elements, leaving insufficient passage for the penetration of an individual. Under these conditions, if a window of this type is used, switching to monitoring mode keeps the window in the open position. Closing is only activated when detected by the sensor.

 Of course, several actuators can share the resources of a single control and programming device and / or of a single or a plurality of sensors.

 In a so-called security mode, all the closing elements accessible to a criminal will be placed in the closed and locked position.

 On the other hand, in a so-called monitoring mode, the invention proposes that certain elements (A) are kept open, other elements (B) are closed and locked, and that other elements (C) are placed in a position partial closure, defined in advance.

 The choice of elements (A), (B) or (C) is defined by the system manufacturer, or by the installer, or finally by the user using the control and programming device. This device is, for example, in the form of a console with keyboard and screen.

<Desc / Clms Page number 9>

 FIG. 3 thus details a form of software execution in the case where several closing elements cooperate in the security and monitoring functions. This program is integrated into the whole supervisory program of the control and programming device.

 The entry point (20) in the monitoring mode is reached if the supervisor program detects that the key (6,16) has given an order to enter the monitoring mode, or else if the supervisor program has been placed in a specific clock mode. In the latter case, it is possible, during an absence of a few days, to ensure that the surveillance mode is activated during the day and that the security mode is activated during the night.

 The software module (21) then proceeds to open the elements of type (A).

 The software module (22) then closes the type elements (B) and possibly their locking.

 The software module (23) partially closes the elements of type (C).

 We then enter the monitoring phase proper, illustrated by the software module (24).

 This software module is itself organized into sub-modules that can be produced by a person skilled in the art and detailed in FIG. 4.

 Finally, the software module (25) tests whether to exit the monitoring mode.

<Desc / Clms Page number 10>

 An exit from the monitoring mode can be caused by an order to switch to another mode sent by the key (6,16) or by the programming clock.

 In FIG. 4, the software module (241) allows the acquisition of the state of the sensor (s) (4,14). The test (242) allows the output if these sensors are not active. If one of the sensors is active, the module (243) proceeds to completely close the elements (B), (C), either entirely, or on the only facade concerned, or near the activated sensor, this choice being configurable in the control and programming device.

 The module (244) makes it possible to send a warning signal to the key (6,16) and to display the location of the detection on screen or LEDs.

 The module (245) finally makes it possible to initiate an alarm procedure (sirens and / or telephone calls) if an obstacle is detected during the complete closing movement.

 The invention further provides that some or all of the sensors (4,14) consist of force and / or movement detection means on the closing elements, or arranged on the kinematic chain comprising the motor and the closing element.

 The invention finally provides that other types of sensors, for example, meteorological (wind, rain, sun ...) are used to allow complete closure of certain closure elements according to these parameters when in mode. monitoring.

 It has been understood that, thanks to the device of the invention, during a detection made during the monitoring mode, the openings or the

<Desc / Clms Page number 11>

 ajar shutters will be automatically closed, while doors that are closed but not locked will be automatically locked.

 Of course, the invention is not limited to the embodiments described and shown by way of example, but it also includes all the technical equivalents, as well as their combinations.
