Definitions
- the present invention relates to the field of security systems for automatic doors and gates. It finds for particularly advantageous application the detection of person or object near a door or a gate and thus allows the protection of specific sites such as for example fire stations, private residences or even storage warehouses. .
- detection system configured to secure automatically operated gates.
- detection technologies There are many detection technologies. Among them, a distinction should be made between detection systems by surveillance zones. These systems typically include proximity sensors that cover or grid a specific area on the ground.
- Document WO2018043511A1 discloses a detection system associated with an automatic sliding door.
- the detection system is configured there in such a way as to detect a person or an object present at the rear of the door.
- detection zones cover the back of the door via several sensors that criss-cross the floor.
- the grid is done using small regular sub-zones that seem to turn on or off as the door opens or closes.
- the small detection sub-zones can be selectively activated or deactivated depending on the door opening status.
- An object of the present invention is therefore to propose a detection system associated with a gate or an automatic door allowing more precise coverage of the detection zones while limiting the number of capture elements.
- Another object of the present invention is to propose a simplified technical solution which can just as well be adapted to the different types of doors, whether for example sliding or swinging.
- an automatic entrance opening device comprising a system which comprises:
- At least one detection element mounted on a support that is immobile relative to the frame and configured to define at least one three-dimensional surveillance zone having an outline and comprising at least one elementary zone, the detection element being configured so that the monitoring varies dynamically between at least a first configuration and a second configuration, different from the first configuration, as a function of the position of the opening, relative to the frame, in which the detection element is configured so that the contour varies according to deforming continuously from the first configuration to the second configuration.
- This allows efficient detection by avoiding sudden changes of zones which may, for example, lead to non-detection phases linked to latencies.
- This technical solution advantageously prevents any interruption in detection during a transition between two different configurations.
- the contour of the surveillance zone will gradually and uninterruptedly, like a fluid, vary from a first shape corresponding to the first configuration up to a second shape corresponding to the second configuration, passing through a whole series of intermediate shapes making it possible to cover singular or difficult-to-access areas.
- the present invention offers better coverage of the space near the gate and therefore more precise monitoring than existing devices.
- the device makes it possible to eliminate "dead zones", corresponding to difficult transitional zones access such as ephemeral nooks, for example.
- the device of the present invention thus allows more intuitive securing approaching human surveillance which would follow the automatic opening of the gaze.
- the device adapts advantageously to the detection of heavy or light vehicles and actively participates in the secure use of automated openings.
- the invention provides a detection method linked to an automatic entrance opening comprising a leaf mounted movable relative to a fixed frame relative to the ground and thanks to a motorization and at least one detection element mounted on a support immobile relative to the frame, the method comprises the following steps:
- the invention provides an automaton linked to an automatic opening device comprising a motorization making it possible to actuate a mobile opening relative to a fixed frame, the automaton is connected to a "LIDAR" type sensor » so as to transmit at least one surveillance zone.
- Another aspect is a computer program product comprising instructions for when executed by a program, such as that of a PLC, performs the process steps.
- FIGS. 1A to 1C show a sectional view along a plane parallel to the ground of an example of evolution of the elementary zones according to the present invention applied to a single-leaf opening device.

- FIG. 4A shows in a perspective view an opening device of the "up-and-over door” type.
- Figures 4B through 4D show the "toggle" opening device in a top view. section along a plane perpendicular to the tilting axis.
- FIGS. 5A to 5C represent, in a cross-sectional view along a plane parallel to the ground, an example of the evolution of detection zones according to the present invention applied to a double-leaf opening device of the “accordion gate” type.
- FIGS. 6A to 6C represent a view, according to a plane parallel to an exterior face of the opening, of an example of evolution of detection zones according to the present invention applied to a sliding opening device.
- Figures 6D to 6F represent another example of the evolution of the detection zones of the same sliding opening device, in a view along a plane parallel to an exterior face of the opening.
- FIG. 7 represents a particular embodiment with an example of distribution of the elementary zones of a lifting opening device, in a view according to a plane parallel to the ground.
- the contour varies dynamically and continuously between the first configuration and the second configuration as a function of an absolute angular position of the motorization, the absolute angular position of the motorization corresponding at a given instant to a precise shape of the contour .
- This preferably allows the surveillance zone to be incremented with precision according to the position of the sash. Indeed, this responds to the problem consisting in making an absolute angular position correspond to a precise shape taken by the contour of the surveillance zone during its deformation between the first configuration and the second configuration.
- a detection element is configured to define the surveillance zone comprising at least two elementary zones, preferably three elementary zones.
- the area covered by the monitoring zone remains constant between the first configuration and the second configuration.
- the openings of a door or of a gate are likely to move within a zone and consequently the surface covered by the front or rear zone of the opening necessarily varies.
- the surveillance zone in section according to at least one plane parallel to the ground, the surveillance zone comprises at least two distinct elementary zones in that they do not overlap with each other.
- the detection element is configured so that the area covered by at least a first elementary zone increases from the first configuration to the second configuration and so that the area covered by a second elementary zone decreases from the first configuration to the second configuration.

- This has the advantage of being able to preferentially define a logical action in association with the presence of an object or a person near the automatic opening device. Indeed, this responds to the problem of accurately locating the presence of a person or an object projected near a portal and triggering an action accordingly.
- the sash comprises an inner face and an outer face distributed symmetrically on each side of the sash and the sash is configured so as to be able to move in translation and/or in rotation relative to the frame and, in section according to at least one plane perpendicular to the ground, a portion of the outline of a first elementary zone is adjacent and parallel to a portion of the inner face and a portion of the outline of a second elementary zone is adjacent and parallel to a portion of the outer face .
- the automatic opening device of the present invention advantageously responds to the problem of defining dynamic zones which, unlike monitoring by static grid, the dynamic variation of the zones adjoining the door allows a distributed and complementary coverage of each side of the sash.
- At least one additional sash is articulated with the sash, the additional sash being configured so as to be able to move relative to the sash, in translation in a direction parallel to the ground and/or in rotation in a direction perpendicular to the ground, the detection element being configured so that at least two portions of the same contour of an elementary zone are respectively and simultaneously parallel and adjacent to a face of the opening and to one side of the additional opening.
- This preferably makes it possible to define a surveillance zone whose outline varies dynamically according to the position of two mobile elements, namely the first opening and an additional opening. Indeed, this can solve the problem of defining a surveillance zone between the two leaves hinged together, preferably, when it comes to folding doors of the "accordion" type with double leaves.
- a first system comprising a first sash and a first additional sash
- a second system comprising a second sash mounted to move relative to an additional frame and a second additional sash hinged with the second sash
- at least one element of detection carried by one of the first system or the second system is configured so as to define an elementary surveillance zone of which two portions of its contour are simultaneously parallel and adjacent to a face of an opening of the first system among the first opening and the first additional opening and to one face of an opening of the second system from among the second opening and the second additional opening.
- an additional elementary zone is configured so as to be able to appear or disappear according to the configuration of the opening relative to the frame, preferably, the additional elementary zone appears or disappears when the opening is in an extreme position corresponding to a total opening or a total closing of the opening relative to the frame, or preferably when a person and/or an object is detected.
- the opening device can, during a transitional phase, cause an unsupervised zone to appear and consequently requires an additional elementary zone which may or may not evolve dynamically with the surveillance zone and simultaneously.
- the "opening device” may comprise a door, a gate, which may for example be sliding, swinging or even folding comprising one or more opening or leaf. It may also be an automatic rising barrier, retractable bollards, retractable studs or safety harrows. It may also be doors or gates that can be controlled along a horizontal or vertical axis.
- area of a zone we mean an area of the zone in a plan according to a section or else as the space occupied by the zone according to a given section.

- FIGS. 6A to 6C We will now describe a particular embodiment of the present invention illustrated in FIGS. 6A to 6C.
- the present invention comprises the system 1 comprising the opening 10 mounted to move relative to the frame 20 fixed relative to the ground as well as a support 21 fixed relative to the frame 20 configured so as to cooperate with the opening 10.
- the opening 10 is configured so as to be able to translate along a horizontal axis so as to free up a passage.
- the device comprises at least one detection element 40 located on at least one support 21 fixed relative to the ground.
- the support 21 is advantageously a support located at the end of the gate, preferably it can also be confused with the frame 20 as an intermediate structure for opening and guiding the opening 10.
- FIG. 6A to FIG. 6C are illustrated three given instants during a closing phase of the device according to a particular embodiment.
- the at least one detection element 40 located on a support 21 generates at least two simultaneous zones among:
- this part may comprise a wall, or any other wall such as a grid or a fence. It is also possible for the opening 10 to be configured to be housed in a space provided for this purpose within a portion of the wall.
- This elementary zone 50 can preferably be designated as a closing collision zone.
- This zone can preferably be designated as a shear zone.
- This area can preferably be designated as an opening collision zone.
- the opening device is partially open.
- the elementary zones are distributed on either side of the frame 20 so as to differentiate the detection according to whether it is:
- a basic 50' zone that may present high safety risks such as a risk of pinching or jamming. For example, a person close to this zone is all the more likely to be injured by having their arm stuck between the frame 20 and the opening 10.
- an elementary zone 50 advantageously located in front of a wall in which is positioned a housing configured so as to be able to accommodate the opening.
- This elementary zone 50′ which can be designated as a shearing zone or a backflow zone when opening, advantageously makes it possible to detect any object or individual likely to be near the housing and to prevent the device from operating correctly.
- the opening device is now closed.
- the 50 Elemental Zone as well as the right portion of the 50' Elemental Zone have been disabled.
- a 50” elementary zone has been activated.
- the elementary zone 50” is located in front of the closed opening 10 and advantageously makes it possible to detect the presence of a person or an object located near the opening 10.
- the elementary zone 50 is activated again but this time it comprises the right portion of the elementary zone 50' of FIG. 6A.
- two additional elementary zones 52 are activated above the two elementary zones 50.50”. This preferentially allows surveillance from above, for example to detect a projectile or an animal which might cross the device.
- the additional elementary zones 52 preferably make it possible to serve as a height limitation for vehicles during an opening phase of the opening 10. For example in detection in the event of crossing the gate and this independently of the elementary zones 50 which secure the gate automatically during its operating phase.
- This embodiment can be implemented for securing during an opening phase with a single detection element 40 configured so as to allow the simultaneous detection of three elementary zones 50, 50' simultaneously.
- the three elementary zones automatically adjust to the height of the opening 10.
- the three elementary zones are distinct.
- the detection element is configured so as to also be able to modify the height of detection automatically and thereby modify the height of the elementary zones 50.
- At least one of the three elementary zones can advantageously be programmed in order to prevent any act of vandalism.
- At least a first detection element 40, and/or an additional detection element 40′, not shown, is configured so as to generate a zone 50′ close to the support 21 like that described in the figures. 6A to 6C.
- At least one detection element among the detection element 40 and the additional detection element 40' which can be different from the first detection element 40, is configured to generate two elementary zones 50, 50” distributed on each side of the zone element 50' so that the entire visible part of the outer face 110' of the opening 10 is covered, in a section along a plane parallel to the opening 10. All of the elementary zones evolve dynamically with the opening 10.
- the elementary zones 50, 50', 50" described in FIG. 6D advantageously move in the opening direction of the opening 10 and in a synchronized manner with the elementary zone 50' which remains fixed with respect to the frame 20 so that the at least elementary zone 50, 50” and the at least elementary zone 50' do not overlap.
- the opening device is in an open configuration. Elemental Zone 50 to the left of Elemental Zone 50' has disappeared. This allows dynamic detection by monitoring zone 5 evolving directly and synchronously with the opening 10.
- the opening device may be suitable for a rising barrier comprising a rail such as opening 10 as illustrated in FIG. 7.
- the detection element 40 simultaneously generates three elementary zones 50, 50', 50” respectively defining an exterior presence detection zone, an interior presence detection zone and a security zone.
- the elementary zone 50′′ is active during the closing phase of the opening 10, while the elementary zones 50, 50′ remain constantly active.
- An equivalent device may be suitable for a tilting barrier, retractable bollards or even retractable studs.
- a base such as the frame 20 configured so as to allow preferential movement 10 and in a direction perpendicular to the ground to studs, for example cylindrical, considered here as openings.
- the pedestal in the open configuration, is anchored in the ground with an elementary zone 50 centered around the pedestal and in the closed configuration, the pedestal is extended, the cylindrical side of the pedestal is entirely exposed entirely outside and the zone detection is wider.
- the area has dynamically expanded continuously in proportion to the displacement vertical of the sash 10.
- the opening device of the present invention can be associated with an alert element which can be a light or sound device, preferably an alarm system.
- an alert element which can be a light or sound device, preferably an alarm system.
- the detection elements 40, 40' can preferably be connected to the alarm system.
- the opening device of the present invention can be associated with a control controlled by an automaton so that the presence or absence of a person or object in the surveillance zone 5 causes a logical action that can automatically trigger a closing or opening of the device.
- the present invention allows the detection of the presence of an object which can be a vehicle or a person by dispensing with carrying out a civil engineering study.
- the “accordion” device illustrated in FIGS. 5A to 5C consisting of several leaves configured so as to fold back on themselves, is ideal for example for entrances to buildings, entrances to parking lots, etc.
- a single detection element 40 may suffice for the embodiments illustrated in FIGS. 2A, 2B, 2C as well as in FIGS. 5A, 5B and 5C when it is positioned in the lower part of the opening or halfway up.
- a single detection element 40 may be sufficient to cover the opening and closing of a swing gate.
- the capture element 40 can be located in the lower part of the opening 10.
- the space is between 10 and 15 cm so that the single detection element 40 can be configured to be able to scan a volume around it at a radius of 180°, and to simultaneously define up to three dynamic elementary zones according to the movement of at least the opening 10.
