Such an air curtain is intended to cover an opening formed in a wall arranged in said plane. The air curtain is a laminar flow of air, uniformly covering the entire height and / or width of the opening. This air curtain forms an air barrier effectively separating the inner zone from the outer zone, notably by preventing exchanges of air and heat between the inner zone and the outer zone, or by preventing the intrusion of dust or insects from the outer zone to the inner zone. The present invention is intended to improve such a device for generating air curtain, improving its functionality and adapting it to the constraints of a confined space such as a rail vehicle. In particular, the object of the invention is notably to provide an air curtain generating device that promotes the flow of people passing through the opening.

The device according to the invention makes it possible to optimize the flow of people in other ways. More particularly, by directing the flow of the air curtain in a direction of diffusion directed towards the exterior of the vehicle, a slight thrust effect of the outgoing persons moving from the inner zone to the outer zone is applied, thus encouraging them to moving in this direction.

The diffusion means comprise nozzles for emission of an air curtain, at least one of the nozzles being arranged to emit the corresponding air curtain vertically, and / or at least one of the nozzles being arranged to emit the corresponding air curtain horizontally. The invention also relates to a cabin, in particular a vehicle cabin, delimiting an inner zone and an outer zone, and comprising a passage opening between the inner zone and the outer zone, comprising an air curtain generating device such as as defined above, arranged to generate the at least 3032391 4 an air curtain covering the passage opening, said passage opening being defined in said plane. Advantageously, the cabin comprises at least one movable door between a closed position in which the passage opening is closed and an open position in which this passage opening is released, the control unit being configured to increase the flow of the at least one air curtain prior to the passage of the door from its open position to its closed position. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, among which: FIG. 1 is a perspective view of a cabin, in particular formed by a rail vehicle car, equipped with an air curtain generating device according to an exemplary embodiment of the invention; - Figure 2 is a schematic sectional view of the cabin of Figure 1 equipped with an air curtain generating device according to a first exemplary embodiment of the invention. - Figure 3 is a schematic sectional view of the cabin of Figure 1 equipped with an air curtain generating device according to a second exemplary embodiment of the invention.
    [0004] FIG. 1 shows a cabin 10, in particular a vehicle cabin and more particularly a cabin formed by a rail vehicle car. The cabin 10 is formed by walls defining together an inner zone 12 and an outer zone 14.
    [0005] At least one of these walls has at least one opening 16 for passage between the inner zone 12 and the outer zone 14. The cabin 10 also comprises, for each passage opening 16, at least one door 18 movable between a position closed in which the passage opening 16 is closed, and an open position in which the passage opening 16 is released.
    [0006] The passage opening 16 extends substantially in a plane P. Thus, the plane P forms a delimitation between the inner zone 12 and the outer zone 14. The cabin according to the invention comprises a device 20 for generating the curtain 1, comprising air curtain generation means comprise air curtain diffusion means, adapted to diffuse at least one air curtain along the plane (P), in at least first and second separate delivery directions.
    [0007] The air curtain generating device 20 comprises a control unit 34 capable of controlling the diffusion of the at least one air curtain in one and / or the other of the first and second diffusion directions. . Advantageously, the first diffusion direction is directed towards the inner zone 12, and the second diffusion direction is directed towards the outer zone 14. Thus, the generation device 20 makes it possible to promote the emission of an air curtain in the first direction when passengers are moving from the outer zone 14 to the inner zone 12, and to promote the emission of an air curtain in the second direction when passengers are moving from the inner zone 12 to the zone An outer air curtain generating device 20 is shown in FIG. 2 according to a first exemplary embodiment of the invention. This generation device 20 comprises means 22 for generating a single air curtain 26. Such an air curtain 26 is also called "air gap" when the air curtain 15 is generated with a width of reduced diffusion, of the order of 10 °. The generation means 22 comprising diffusion means 24 diffusing the air curtain 26 along said plane P. The diffusion means 24 comprise, for example, air curtain emission nozzles 26, arranged near the plane P These emission nozzles are fed by a blower 27 via a suitable pipe 29. The blower 27 advantageously makes it possible to supply the air emission nozzles with a variable flow and / or temperature. The generation device 20 according to the invention also comprises means for modifying the orientation of the diffusion means 24, between a first position 25 in which the air curtain 26 is diffused in a first direction of diffusion D1, directed to the inner zone 12, and a second position in which the air curtain 26 is diffused in a second direction of diffusion D2 directed towards the outer zone 14. For example, the orientation modification means allow a rotation of the means of rotation. 24, and more particularly the nozzles, so that the air curtain 26 diffused is directed in the desired direction of diffusion. Advantageously, the diffusion means 24 can take a plurality of angular positions, between a first angular position in which the air curtain 26 is diffused in the first diffusion direction D1, and a second angular position in which e air curtain 26 is broadcast in the second diffusion direction D2.
    [0008] The angular position of the diffusion means 24 is controlled by the control unit 34, depending on the situation. For example, the diffusion means 24 are oriented so that the air curtain 26 is emitted towards the inner zone 12 (first diffusion direction D1) when passengers are riding in the vehicle and towards the outer zone 14 (second direction D2) when passengers get off the vehicle.
    [0009] In the example described, the nozzles are arranged to emit the air curtain 26 vertically, from top to bottom. According to a variant not shown, the nozzles are arranged to emit the corresponding air curtain horizontally. Likewise, certain nozzles may be arranged on either side of the opening 16, and emit air flows that meet to form the corresponding air curtain. Advantageously, the control unit 34 for controlling the air curtain 26 is able to regulate the flow and / or the temperature of the air of this air curtain 26 and able to control the air curtain 26 in a direction of desired distribution. For this purpose, the control unit 34 is able to control the blower 27 15 supplying the air curtain 26 and to control the orientation modification means allowing the diffusion means 24 to be rotated so as to orient the curtain. air 26 according to the desired direction of diffusion. Controlling the direction of diffusion of the air curtain 26 by the control unit 34, via the orientation modification means, makes it possible to optimize the passage of persons 20 through the opening 16. More particularly, when the cabin 10 is a rail vehicle car, this optimizes the flow of passengers in station. For example, the control unit 34 is adapted to pass in a first mode of operation, in which the flow of the air curtain 26 is directed in the first diffusion direction D1, towards the interior zone 12, to promote the displacement of persons 25 from the outer zone 14 to the inner zone 12. In this case, the air curtain 26 has a tendency to drive the entrants from the outer zone 14 towards the inner zone 12, and to incite them to move away from the people stationing in the inner area 12 near the opening 16, likely to hinder the passage of people entering. The first diffusion direction D1 forms, for example, an angle of 15 ° with the plane P. The control unit 34 is also able to pass into a second mode of operation, in which the flow of the air curtain 26 is directed in the second diffusion direction D2, to the outer zone 14, to facilitate the movement of people to the outer zone 14. In this case, the air curtain 26 has a tendency to cause the outgoing persons from the inner zone 12 to the outer zone 14, and to encourage 3032391 7 deviate from people stationing in the outer zone 14 near the opening 16, likely to hinder the passage of people outgoing. The second diffusion direction D2 forms for example an angle of 20 ° with the plane P.
    [0010] The passage from the first to the second operating mode can be delayed from the opening of the door 18, for example to favor the exit of people during a first delay following the opening of the door 18, then to favor the entry of persons during a second time delay, prior to closing the door 18.
    [0011] Alternatively, or in addition, the device 20 comprises means 36 for detecting people in the vicinity of the plane P. In this case, the control unit 34 is able to adjust the direction of diffusion of the air curtain 26. function of the presence and / or movements of persons in the vicinity of said plane P. Thus, instead of delaying the first and second modes of operation, the control unit 34 remains in the second mode of operation as long as people are detected as moving from the inner zone 12 to the outer zone 14, and then remains in the first operating mode as long as people are detected as moving from the outer zone 14 to the inner zone 12. According to another variant, the The first or second mode of operation can be controlled manually, in particular by the driver of the railway vehicle and / or by an agent in the station. Moreover, the control unit 34 is advantageously able to reduce the flow of the air curtain 26 when the people are detected near the plane P, for reasons of comfort of these people.
    [0012] Alternatively or in addition to the operating modes mentioned above, the control unit 34 advantageously has a third mode of operation in which the flow of the air curtain 26 is increased, prior to the passage of the door 18 since its open position to its closed position, in order to encourage people close to the plane P to move away from this plane P, so as not to hinder the closing of the door 18. Alternatively, this increase of flow is performed only when at least one person is detected near the plane P by the detection means 36. Advantageously, the device 20 comprises means 38 for detecting weather conditions in the outer zone 14, for example arranged on the control unit 34. These detection means 38 are particularly suitable for measuring a temperature in the outer zone and / or for detecting rain or snow and / or for detecting the temperature. at wind speed. The control unit 34 is then able to adjust the flow and / or the temperature of the air curtain 26 as a function of the meteorological conditions detected.
    [0013] The temperature of the air curtain 26 may in particular be increased when the measured outside temperature is below a predetermined threshold, and / or when this is controlled manually. Likewise, the temperature of the air curtain 26 can be lowered when the detected outdoor temperature is above a predetermined threshold, and / or when manually controlled. The optimum temperature for the air curtain can be calculated by the control unit 34 as a function of the outside temperature, or alternatively be chosen manually. Advantageously, the control unit 34 is configured to increase the flow of the air curtain when rain or wind is detected. Thus, the air curtain 26 has a drying effect for passengers passing through and protection against the wind. Advantageously, the control unit 34 is configured to interrupt the air curtain 26 when the door 18 is in the closed position or after a delay following the closing of this door. In this case, this air curtain 26 is reactivated 20 prior to the opening of the door 18, including station, for example to encourage people close to the door 18 to back before opening. In a variant, the control unit 34 is configured to maintain the activated air curtain even when the door 18 is closed, in order to optimize the thermal insulation of the latter, and thus to keep the interior 12 inside. optimal conditions of air conditioning. It will be noted that, alternatively, the orientation of the air curtain could be based on a ventilation principle. FIG. 3 shows a device 20 for generating an air curtain according to a second exemplary embodiment of the invention. In this FIG. 3, the elements similar to those of FIG. 2 are designated by identical references. According to this second exemplary embodiment, the air curtain generating device 20 comprises first means 22 for generating a first air curtain 26, comprising first diffusion means 24 diffusing the first curtain of air air 26 along said plane P, in the inner zone 12. Advantageously, the first diffusion means 24 are oriented so that the first air curtain 26 does not cross the plane P.
    [0014] The first diffusion means 24 comprise, for example, first emission nozzles of the first air curtain 26, arranged close to the plane P and oriented to emit the first air curtain 26 towards the interior zone 12, in the first direction of diffusion D1. The first emission nozzles are fed by a blower 27 via a suitable pipe 29. The blower 27 advantageously makes it possible to feed the first air emission nozzles with a variable flow and / or a variable temperature. The generation device 20 according to the invention also comprises second means 28 for generating a second air curtain 30, comprising second diffusion means 32 diffusing the second air curtain 30 along said plane P in the outer zone 14. Advantageously, the second diffusion means 32 are oriented so that the second air curtain 30 does not cross the plane P. The second diffusion means 32 comprise second emission nozzles of the second air curtain 30, arranged near the plane P and oriented to emit the second air curtain 30 to the outer zone 14, in the second diffusion direction D2. The second emission nozzles are fed by a blower via a pipe 31 adapted. The blower advantageously makes it possible to supply the second air emission nozzles with a variable flow and / or temperature. For example, the same blower feeds the first and second emission nozzles, however with separate branches, having separate and independent means of changing the flow and the air temperature of the corresponding air curtain.
    [0015] Alternatively, each of the first 26 and second 30 air curtains is generated by a separate blower. The first 26 and second 30 air curtains, by their proximity interact with each other, according to the principle called Venturi effect, allowing, generating together a resulting air flow diffusing in a resulting direction.
    [0016] The control unit 34 is adapted to modify said resultant direction by modifying the relative pressures of each air curtain, without requiring a mechanical orientation system. In a preferred embodiment, to enhance the Venturi effect, the air curtains 26, 30 are generated with a reduced diffusion width, of the order of 10 °, thereby forming air knives. For this purpose, the emission nozzles are adapted to generate such air blades. For example, the emission nozzles are of the Coanda effect type.
    [0017] In the example described, the first and second nozzles are arranged to emit the first 26 and second 30 air curtains vertically, from top to bottom. Alternatively, the first and second nozzles could be arranged to emit the air curtains from bottom to top. It should be noted that some nozzles could be arranged at the bottom, being directed upwards, and others at the top, being directed downwards, to generate two air flows, one directed downwards. and the other upward, joining together to form the corresponding air curtain. According to a variant not shown, the first and second nozzles are arranged to emit the corresponding air curtain horizontally. Likewise, certain nozzles may be arranged on either side of the opening 16, and emit air streams that meet to form the corresponding air curtain. The generation device 20 further comprises a unit 34 for controlling the first 26 and second 30 air curtains, adapted to regulate the flow and / or the temperature of the air of the first air curtain 26 and / or this second air curtain 30. For this purpose, the control unit 34 is able to control each blower supplying the first 26 and second 30 air curtains. Controlling the orientation of the resulting air curtain by the control unit 34 by adjusting the flow of the first 26 and second 30 air curtains optimizes the passage of people through the opening 16. particularly, when the cabin 10 is a rail vehicle car, this makes it possible to optimize the flow of passengers in the station. For example, the control unit 34 is adapted to pass in a first mode of operation, wherein the flow of the first air curtain 26 is increased and the flow of the second air curtain 30 is reduced, to promote the displacement from the outer zone 14 to the inner zone 12. In this case, the resultant airflow tends to drive the entrants from the outer zone 14 to the inner zone 12, and to incite to move away from the people stationing in the inner area 12 near the opening 16, likely to hinder the passage of people entering. Conversely, the control unit 34 is also adapted to move into a second mode of operation, wherein the flow of the first air curtain 26 is reduced and the flow of the second air curtain 30 is increased to directing the resulting airflow to the outside and favoring the movement of people to the outer area 14. In this case, the resulting airflow tends to drive the outgoing persons from the inner area 12 to the outer area 14 and to incite to move away from people stationing in the outer zone 14 near the opening 16, likely to hinder the passage of 35 outgoing persons.
    [0018] The passage from the first to the second operating mode can be delayed from the opening of the door 18, for example to favor the exit of people during a first delay following the opening of the door 18, then to to favor the entry of persons during a second delay, prior to the closing of the door 18. Alternatively, or in addition, the device 20 comprises means 36 for detecting people near the plane P. In this case, the control unit is adapted to adjust the flow of the first 26 and / or the second 30 air curtains depending on the presence and / or movement of people in the vicinity of said plane P. Thus, instead of delaying the first 10 and second modes of operation, the control unit 34 remains in the first mode of operation as long as people are detected as moving from the inner zone 12 to the outer zone 14, and then remains in the second operating mode as long as people are detected as moving from the outer zone 14 to the inner zone 12.
    [0019] According to another variant, the passage in the first or second operating mode can be controlled manually, in particular by the driver of the railway vehicle and / or by a station agent. Furthermore, the control unit 34 is advantageously able to reduce the flows of the first 26 and second 30 air curtains when the people are detected near the plane P, for reasons of comfort of these people. Alternatively or in addition to the operating modes mentioned above, the control unit 34 advantageously has a third mode of operation in which the flow of the first 26 and / or the second air curtain is increased, before the passage of the door 18 from its open position to its closed position, in order to induce persons in the vicinity of the plane P to move away from this plane P, so as not to hinder the closing of the door 18. As a variant, this increase in flux is achieved only when at least one person is detected near the plane P by the detection means 36. Advantageously, the device 20 comprises means 38 for detecting weather conditions in the zone. 14, for example arranged on the control unit 34. These detection means 38 are particularly suitable for measuring a temperature in the outer zone and / or for detecting rain or snow and / or to detect the wind speed. The control unit 34 is then able to adjust the flow and / or the temperature of the first 26 and / or the second air curtain according to the detected weather conditions.
    [0020] The temperature of the air curtains can in particular be increased when the measured outdoor temperature is below a predetermined threshold, and / or when this is controlled manually. In this case, the temperature of the second air curtain 30 is preferably lower than that of the first air curtain 26, so that the temperature 5 evolves progressively from the outer zone 14 to the inner zone 12. temperature of the first 26 and / or second 30 air curtains can be lowered when the detected outside temperature is above a predetermined threshold, and / or when manually controlled. In this case, the temperature of the second air curtain 30 is preferably greater than the temperature of the first air curtain 26, so that the temperature gradually changes from the outer zone 14 to the inner zone 12. The optimum temperatures for the air curtains can be calculated by the control unit 34 according to the outside temperature, or alternatively be chosen manually.
    [0021] Advantageously, the control unit 34 is configured to increase the flow of the two air curtains 26, 30 when rain or wind is detected. Thus, the resulting airflow has a drying effect for passengers passing through and protection against the wind. Advantageously, the device 20 further comprises means 40 for air conditioning the inner zone 12, suitable for passing into different air conditioning conditions of the inner zone 12, in particular as a function of the meteorological conditions in the outer zone 14. Air-conditioning means 40 are capable of modifying the temperature in this interior zone 12. These air-conditioning means 40 are, for example, conventional means equipping a state-of-the-art railway car. The control unit 34 is connected to these air conditioning means 40, and is capable of adjusting the flow and / or the temperature of the first air curtain 26 and / or the second air curtain 30 as a function of the Condition of the air conditioning means 40. In particular, the first air curtain 26 is heated or cooled substantially to the same temperature as that provided in the interior zone 12 by the air conditioning means 40. Advantageously, the control unit 34 is configured to interrupt the second air curtain when the door 19 is closed position or after a delay following the closing of this door. In this case, the second air curtain 30 is reactivated prior to the opening of the door 18, especially at the station, for example to 3032391 13 to encourage people close to the door 18 to back before its opening . On the other hand, the first air curtain 26 is advantageously kept activated even when the door 18 is closed, in order to optimize the thermal insulation thereof, and thus to maintain the interior 12 under optimal conditions of air-conditioning. Note that the invention is not limited to the embodiment described but could have various variants. In particular, other operating configurations of the air curtains and orientation may be envisaged, possibly involving more than two air curtains or air gaps.
