Description

TECHNICAL FIELD OF THE INVENTION The invention relates to air transport installations, in particular the transport of passengers. State of the art

Currently, there are amusement parks with air rides where vehicles carrying people are suspended above the ground on overhead rails and each vehicle has wheels attached to the top of the vehicles to roll them along the rails. These rides may be of the "thrill" type when their circuits have steep slopes. Other rides are of the "discovery" type with low slopes, to allow people to visit the characteristic places of the amusement park. In general, the speeds of "discovery" type rides are low compared to those of thrill rides.

To move the vehicles along the rails of the rides of the type discovered, the wheels of the vehicles are generally driven by an electric motor mounted on the vehicles. The vehicles may also include a plurality of electric motors capable respectively of driving the wheels or pairs of wheels. But such engines are bulky and weigh down the vehicles. In addition it is necessary to equip the vehicles with batteries to power the engines, which clutters even more the vehicles. In addition, the electric motors of each vehicle must be synchronized with each other to avoid any risk of collision between vehicles.

OBJECT OF THE INVENTION The object of the invention is to remedy these drawbacks, and more particularly to provide an air transport facility that can offer enhanced security for users, in particular by limiting the risk of collision between vehicles.

Another object of the invention is to provide an air transport facility for increasing the passenger transport rate.

According to one aspect of the invention, there is provided an air transport facility, comprising at least one traffic lane for vehicles comprising a main rail suspended above the ground and having at least one curvature, and at least one vehicle provided with a set of main wheels configured to roll on the main rail.

The traffic lane comprises a towing aerial cable, a drive means configured to drive the cable, and guiding means configured to guide the cable along the main rail, the vehicle comprising a hooking means configured to hook the vehicle. to the cable.

Thus, by equipping an air transport facility with a towing cable and by hooking the vehicles to the towing cable, an installation is provided which makes it possible to increase the speed of movement of the vehicles compared with the rides of the type that is being discovered. Such an installation makes it possible to increase the flow of the passengers, while reducing the risks of collision between vehicles during the transport of the passengers, because the vehicles are hooked on the same towing cable during the transport.

A first traffic lane may surround a second lane in order to create a separation space between the first and second lanes.

The two lanes increase the availability of vehicles for re-embarkation or disembarkation of passengers. Indeed, it can stop the traction cable towing a first path, for example to maintain, or in case of failure, while maintaining the possibility of using the tow rope of the second way. Such an installation thus makes it possible to ensure the redundancy of the drive of the vehicles and guarantees a high transport rate.

The main rail of at least one traffic lane may comprise several horizontal curvatures, and the lane guide means comprise horizontal deflection rollers on which the lane of the traffic cable bears so as to deflect it in parallel. horizontal curvatures. The installation creates traffic lanes with horizontal curvatures to reach different locations that are not necessarily aligned. It can be noted that the current facilities of the cable car type do not allow such horizontal curvatures between two loading / unloading stations of the passengers. Indeed, for cableways equipped with a single cable both tractor and carrier, there are no towers deflecting the cable in a horizontal curvature between two stations because the clamp of vehicles towed at a high speed could come out of pylon rollers due to the high pulling speed. Moreover, the cable cars with a towing cable and one or more carrying cables, are also not equipped with such towers between two stations, because the horizontal deflection of the carrying cables would bend the carrying cables with a pronounced angle that could make derail the vehicle passing on the carrier cables at high speed. The main rail having horizontal curvatures according to the invention therefore allows vehicles to move at high speed along a traffic lane having horizontal curvatures between two stations.

The main rail of at least one traffic lane may also comprise several vertical curvatures, and the lane guide means comprise a plurality of compression rollers pressing on the cable of the taxiway so as to guide it parallel to the curvatures. vertical.

The guide means of at least one traffic lane may comprise a plurality of support rollers supporting the cable of the taxiway above the ground.

At least one taxiway may have a secondary rail suspended above the ground parallel to the main rail of the taxiway, and the taxiway vehicle is provided with a set of secondary wheels configured to ride on the rail secondary.

The means for attaching the vehicle to at least one traffic lane may be configured to removably hook the vehicle to the laneway cable. The facility may further include a station for unloading and embarkation of passengers in the vehicle of at least one taxiway, the vehicle comprising a grip plate and the station comprising a set of drive wheels for to cooperate with the adhesion plate of the vehicle to drive along the main rail of the taxiway when it is unhooked from the cable of the taxiway.

The driving means of at least one traffic lane may comprise a driving pulley for driving the cable of the traffic lane, and means for tensioning the cable of the lane.

The main rail and the secondary rail of at least one traffic lane can respectively form two closed loops.

The main rail and the secondary rail of at least one traffic lane may be continuous.

The vehicle of at least one traffic lane may comprise a carriage and a cab removably mounted on the carriage, the carriage comprising displacement means configured to lower and mount the car relative to the carriage.

FIG. 1 shows an air transport installation 1 comprising at least one traffic lane 2, 3 for vehicles 4, 5. Each lane 2, 3 comprises a main rail 6, 7 suspended above ground, also noted external rail, for guiding the vehicles 4, 5 along the track 2, 3. Each lane 2, 3 also comprises one or more supports 8 on which the main rails 6, 7 are mounted in suspension relative to the ground 9, as illustrated in FIGS. 4 and 5.

In particular, each main rail 6, 7 forms a closed loop. Preferably, each main rail 6, 7 is continuous. Each main rail 6, 7 comprises at least one curvature 10 to 20 so as to guide the vehicles 4, 5 in different places, including non-aligned locations. Each main rail 6, 7 may comprise horizontal bends 10 to 16 parallel to the ground. The horizontal bends 10 to 16 may be internal horizontal bends 10, 11, 12, 13, and 16 oriented towards the interior of the traffic lane 2, 3, also noted concave horizontal curvatures, to guide the vehicles 4, 5 to the interior of the traffic lane 2, 3, or external horizontal bends 14, 15 oriented towards the outside of the lane 2, 3 to guide the vehicles 4, 5 towards the outside of the lane 2, 3, so-called convex horizontal curvatures. Furthermore, each main rail 6, 7 may further comprise vertical curvatures 17 to 20 perpendicular to the ground. The vertical bends 17 to 20 may be convex vertical bends 18, 19 with respect to the ground or concave vertical bends 17, 20 with respect to the ground, in order to guide the vehicles 3, 4 upwards or downwards. Each lane 2, 3 may comprise rectilinear sections 21 to 23 in which the main rail 6, 7 is rectilinear. FIG. 1 shows an example of installation 1 comprising a traffic lane 2 in which the main rail 6 describes a closed loop comprising, successively, a concave horizontal curvature 10, a concave vertical curvature 17, a convex vertical curvature 18, a concave horizontal curvature 11, a convex vertical curvature 19, a concave vertical curvature 20, a concave horizontal curvature 12, another concave horizontal curvature 13 having a radius of curvature greater than that of the previous one, a rectilinear section 21, and then a convex horizontal curvature 14, a rectilinear section 22, a convex horizontal curvature 15 a rectilinear section 23, and a concave horizontal curvature 16. The installation 1 may comprise a single vehicle 4 or more vehicles 4, 5. In addition each channel of circulation 2, 3 may comprise one or more vehicles 4, 5. Each vehicle 4, 5 comprises a cabin 24, or one or more seats, for carrying passengers, and a set of main wheels 25 configured to allow the vehicle 4, 5 to roll on the main rail 6, 7. More particularly, each vehicle 4, 5 comprises a carriage 26 on which the cab 24 is mounted and all the main wheels 25. The air transport facility 1 also comprises at least one station 27 to 30 for unloading and loading passengers in the vehicles 4, 5. Furthermore, each traffic lane 2, 3 also comprises a towing aerial cable 31, 32, a drive means 33 of the cable 31, 32, and guide means 34 for guiding the cable 31, 32 along the main rail 6, 7 of the taxiway 2 , 3.

The guide means 34 comprise rollers 35 to 37, that is to say small grooved wheels so that a cable 31, 32 can pass inside the groove. The rollers 35 to 37 may be support rollers 35 for supporting the cables 31, 32 above the ground, and on which the cables 31, 32 are placed in abutment. All support rollers 35 are not shown in FIG. 1, for reasons of simplification. Note that there are several support rollers 35 located along each of the lanes 2, 3 to maintain the cables 31, 32 above the ground. The rollers may also be horizontal deflection rollers 36 for guiding the cables 31, 32 parallel to the horizontal curvatures of the main rails 6, 7, and on which the cables 31, 32 are supported. More particularly, the horizontal deflection rollers 36 are parallel to the ground, that is to say that their axes of rotation are vertical. The rollers may be compression rollers 37 which press on the cables 31, 32 so as to guide them parallel to the vertical curvatures of the main rails 6, 7, that is to say upwards or downwards. Furthermore, the main rails 6, 7 may have inclined curvatures, that is to say neither vertical nor horizontal, and the rollers may be inclined to guide the cables 31, 32 parallel to the main rails 6, 7. From generally, the rollers 35 to 37 are located along the traffic lanes 2, 3 so that the cables 31, 32 follow the lane 2, 3 while remaining parallel to the main rails 6, 7. Thus, as illustrated in Figure 1, to maintain the cable 31 substantially parallel to the main rail 6, one or more horizontal deflection rollers 36 are located at each horizontal curvature 10 to 16 of the main rail 6. More particularly, at each horizontal curvature 10, 11, 12, 13, and 16, horizontal deflection rollers 36, said internal, are located inside the closed loop described by the cable 31 to guide it inwardly of the loop. On the contrary, at each horizontal outer curvature 14, 15, horizontal deflection rollers 36, said external, are located outside the cable 31 to guide it outwardly of the loop. In addition, support rollers 35 are situated under the cable 31 along the circulation path 2, and more particularly at the level of the concave vertical curvatures 17, 20. Compression rollers 37 are situated at the level of the convex vertical curvatures 18, 19. It is noted in FIG. 1 that the traction cable 31 is rectilinear between two successive deflection rollers 36. The towing ropes 31, 32 are configured so that their bending does not derail the vehicles 4, 5.

In general, the cables 31, 32 are intended to tow the vehicles 4, 5 along the main rail 6, 7. More particularly, the cables 31, 32 are kept suspended above the ground parallel to the main rails 6, 7 in order to tow the vehicles 4, 5 along the taxiway 2, 3. The drive means 33 of a track 2, 3 is configured to drive the cable 31, 32 of the track 2, 3. The means drive 33 channels 2, 3 are preferably located within the same station 27, denoted driving station. When the installation 1 comprises two lanes 2, 3, as illustrated in Figure 2, the drive means 33 may be located in two separate stations. Each drive means 33 comprises a motor 38, a drive pulley 39 driven by the motor 38 and configured to drive the cable 31, 32 of a traffic lane 2, 3, and tensioning means 40 of the cable 31. , 32 of track 2, 3. Motors 38 of tracks 2, 3 may be electric or internal combustion.

The tensioning means 40 of a towing cable 31, 32 may comprise a return pulley 41, as illustrated in FIGS. 7 to 9. The tensioning means 40 may also comprise two return pulleys 41, 42, such as illustrated in Figure 6.

In addition, each vehicle 4, 5 comprises an attachment means 43 configured to hook the vehicle 4, 5 to the aerial cable 31, 32. Thus, when the vehicles 4, 5 are hooked to the cable 31, 32, they can ride on the main rail 6, 7 by the traction exerted by the cable 31, 32. According to one embodiment, each hooking means 43 is configured to fix the vehicle 4, 5 fixedly to the cable 31, 32. For example, the attachment means is a fixed clamp, and the vehicle 4, 5 is secured to the cable 31, 32 permanently. In this case, the driving means 33 must be stopped so that the vehicles 4, 5 remain stationary so that the passengers can embark or disembark in the vehicles 4, 5. In this embodiment, a first station 27 allows a boarding and a disembarkation of passengers and a second station 28 is used to embark and disembark passengers at another location. In particular, the second station 28 is located so that the route of the lanes 2, 3, to go from the first 27 to the second station 28, is equal to the course to go from the second 28 to the first station 27 in the same direction of circulation. In this case, the vehicles 4, 5 are fixedly attached to the cable 31, 32 and when a vehicle 4, 5 is located at the first station 27, a second vehicle 4, 5 is located at the second station 28. The use of fixed clamps 43 requires that the vehicles can not bypass the driving pulley 38 of the traffic lane 2, 3. It must therefore stop the cable 31, 32 before a vehicle 4, 5 crosses the driving pulley 38, then drive it again in a direction of opposite scroll. Advantageously, when using stationary clamps 43, the stations 27 to 30 are simpler to achieve because it is no longer necessary to unhook the vehicles station.

According to another preferred embodiment, each attachment means 43 is configured to removably hook the vehicle 4, 5 to the cable 31, 32. For example, the attachment means 43 is a clip, said disengageable, which can open to disengage the vehicle from the cable 31, 32, or close to grip the cable 31, 32 and make the vehicle integral with the cable 31, 32, that is to say to mechanically link the vehicle 4, 5 to cable 31, 32. In other words, the vehicles 4, 5 are hooked to the cables 31, 32 between two stations 27 to 30 to be towed along the main rails 6, 7 at a determined speed which is equal to the speed of the towing cable 31, 32. On the contrary, the vehicles 4, 5 can be detached from the cable 31, 32, or unhooked, when the vehicles 4, 5 enter a station 27 to 30. When the vehicles are separated from the cable 31, 32, they are kept hanging on the main rails 6 7. Thus, the vehicles 4, 5 unhooked can be moved at a speed that is less than that of the towing cable 31, 32, in particular to facilitate re-embarkation and disembarkation of the passengers. The advantage of the disengageable clips 43 is that the vehicles can bypass the driving pulley 38 of the traffic lane 2, 3. It is therefore possible to drive the towing cable 31, 32 of the lane 2, 3 in the same uninterrupted direction of travel. . The cables 31, 32 are only towing cables, that is to say that the cables 31, 32 do not intervene in the suspension of the vehicles 4, 5. In other words, the vehicles 4, 5 are not not suspended from the cables 31, 32, but suspended from the main rails 6, 7, in particular by means of the assembly of the main wheels 25. In order to be able to move the unhooked vehicles 4, 5, each vehicle 4, 5 comprises a plate 46 and each station 27 to 30 comprises a set of drive wheels 47, illustrated in Figures 3, 4, 5, 6, 7 and 10, intended to cooperate with the adhesion plates 46 to drive the vehicles 4 , 5 unhooked along the main rails 6, 7. Thus, the passengers can board and unload vehicles 4, 5 without having to stop the drive means 33 of the cables 31, 32. In this case, it is not necessary to necessary to decrease the speed of cables 31, 32 when people emb Arise or land vehicles 4, 5.

Alternatively, the traffic lanes 2, 3 each comprise a secondary rail 48, 49 suspended above the ground, also noted internal rail, parallel to the main rail 6, 7 of the traffic lane 2, 3. alternatively, each vehicle 4, 5 is provided with a set of secondary wheels 50 configured to allow the vehicle 4, 5 to roll on the secondary rails 48, 49. Each secondary rail 48, 49 cooperates with a main rail 6, 7 d a traffic lane 2, 3 to ensure a more stable suspension for the vehicles 4, 5 of the track 2, 3. In this variant, the secondary rails 48, 49 comprise curvatures corresponding to those of the main rails 6, 7 with they cooperate, in order to travel the lane 2, 3 while remaining parallel to the main rail 6, 7 of the track 2, 3. In particular, the secondary rails 48, 49 also form closed loops. Preferably, the secondary rails 48, 49 are continuous.

FIG. 2 shows another embodiment of the installation 1, in which the installation 1 comprises a first circulation lane 2, describing a first closed loop, and a second lane of circulation 3 surrounded by the first channel 2, so as to create a separation space 51 between the first and second channels 2, 3. The separation space 51 allows, for example, to place a loading dock 52 between the two channels 2, 3, to reduce the lateral bulk of the station 27. For example one can place loading docks 52 outside the first lane 2, and loading docks 52 inside the second lane 3.

FIG. 3 shows a vehicle 4 entering the driving station 27. There is also shown an embodiment of the set of drive wheels 47, in which the drive wheels 47 have their axes of rotation. located vertically. In this embodiment, the adhesion plate 46 is vertical, and when the vehicle 4 enters the station 27, the adhesion plate 46 circulates between the drive wheels 47 to brake the vehicle 4. When the vehicle 4 is sufficiently slowed, it can be unhooked from the cable 6 by opening the clamp 43. In general, the stations 27 to 30 are equipped with motors 53 to control the rotation of the drive wheels 47. Thus, the vehicles can be moved 4 Disconnected from the cables 31, 32, along the traffic lanes 2, 3 within a station 27 to 30. When a vehicle 4, 5 is unhooked, a group of passengers can disembark from the vehicle 4, 5, then another group of passengers can board the vehicle 4. To then hang the vehicles 4, 5 to the cables 31, 32, the drive wheels 47 accelerate the vehicles 4, 5 and the disengageable clips 43 close on the cables 31 , 32.

FIG. 4 shows an embodiment of the main rail 6 and the secondary rail 48 of a traffic lane 2, and of a vehicle 4 suspended on the rails 6, 48.
