DESCRIPTION

This patent is related to transportation systems for people and/or things and in particular concerns a new transportation system for people and/or things, which uses electric vehicles that travel on non- electrified rails.

Various systems to transport goods and/or people using small vehicles that run on rails are already known in the prior art.

The need to transport people in very large places or spaces, but without using common motorized vehicles which increase traffic and increase atmospheric and acoustic pollution, is well known. The high number of vehicles in fact leads to a slowing down of circulation, which becomes discontinuous, as well as the risk of accidents and collisions between the vehicles themselves.

For example, tourist resorts are frequented by people who, not knowing the topography of the place, struggle and are uncomfortable circulating with their own vehicles and prefer to use paid public transport, such as buses, taxis, and so on.

There are also very large places, such as airports, or locations where precise restrictions prohibit the use of private vehicles. Here people must travel on foot or according to the methods offered, for example using moving walkways or shuttles.

These transportation systems, in particular moving walkways, have obligatory routes, which do not include intermediate stops except those which are pre-established. In addition, particularly with regard to shuttles and buses, they are designed to accommodate many people all together, but in this case the user cannot enjoy a quiet trip and also the bus or shuttle must stop whenever a user has to get on or off at an intermediate stop.

The document CA0277221 concerns a transportation system that includes a rail with a central groove in which a shank constrained to a vehicle slides. The system also comprises a vehicle configured to travel both on the roadway and on the rail, this vehicle comprising a vehicle structure supported by a plurality of wheels. The shank is mounted on the structure and can shift from a retracted position to an extended position, and wherein a drive wheel is mounted at the end of the shank which is suited to engage in the groove of the rail to guide the vehicle along the rail itself. The vehicle can operate in two ways: in the road transit mode the vehicle operates its own drive wheels, while in the transit mode on the rail, the vehicle activates the drive wheel. An on-board computer controls the vehicle's movement on the rail.

US7652629 relates to a transportation system for vehicles, comprising a plurality of lane segments suited to be juxtaposed with each other to form a lane for wheeled vehicles. Each segment comprises two box-shaped and hollow tracks, inside which the cables for the electric power supply of the vehicles are housed.

US2011/0196561 concerns an electric powered transportation network with customized vehicles that can automatically transport passengers. The vehicles travel on two continuous concrete strips, in turn equipped with electrical conductors. The vehicles are in turn equipped with electrical contacts for the electrical connection with the strip conductors, through which the vehicles are powered.

US4132175 relates to a transportation vehicle comprising support wheels and a guide wheel inserted in a guide beam that protrudes from the road. These support wheels run on raised tracks with respect to the road surface, so that between the two tracks a wide depression is formed having a width equal to the distance between the wheels. This document also suggests the need to use two side-by-side guide members that run on both sides of the guide itself for stability. The system structured in this way cannot therefore be constructed on road surfaces normally used by other vehicles, such as bicycles, motorbikes, or motor vehicles.

US3822648 relates to a guiding system for computer controlled vehicles, comprising a flat track guide-way and a guide channel beneath the track surface. This system is also not suitable to be built on just any road level, like a normal road or a cycle path, but on a specially dedicated rail.

WO2011/045446 relates to a kind of sensing assembly, to be installed frontally on the vehicle to be driven, and where the assembly comprises a guide unit suited to be inserted in a rail. The guide unit follows the rail and moves such that the information related to curvature of the rail is transmitted through mechanical and/or electronic means to the wheels of the vehicle. This guide unit must therefore necessarily be installed in front of the vehicle, and in particular in front of the steering axle of the front wheels of the vehicle, so as to be able to promptly modify the position of the vehicle's drive wheels. Moreover, the guide unit shown in this document is pressed by a spring to slide against the bottom of the rail, where various types of debris accumulate, which may hinder or even prevent the normal forward movement of the guide unit itself.

US2007/124035 relates to a traffic system where the vehicles are equipped with wheels that run on driving bridges raised with respect to the road surface and a steering device that slides on the road surface.

The object of the present patent is a new type of transportation system for people which uses electric vehicles that travel constrained to rails.

The main object of the present invention is to make the transportation system installable on any type of pre-existing or dedicated road surface, where other types of vehicles such as bicycles, motor vehicles or motorbikes can circulate, without impeding the circulation by any other means of transport once the rail is installed.

Another important object of the present invention is to minimize the construction works necessary for its installation on existing road structures and consequently to have very low costs and production times.

Yet another important object of the present invention is to enable the autonomous driving of each vehicle, which is autonomously powered, and which always remains constrained to the rails.

Still another object of the present invention is that it can be installed in any environment or location, where it is advantageous to eliminate or reduce private vehicle traffic on the road.

A further object of the present invention is to reduce the risk of collisions between vehicles, since the latter circulate constrained to rails and are also equipped with a control system to monitor their mutual positions.

Another object of the present invention is to make the rail system structurally simpler in that it does not supply the power to the vehicles which are autonomously powered.

Still another object of the present invention is to ensure the maximum safety of the rail system since, thanks to the devices described and claimed below, the dirt and debris along the rail is minimized, and the correct positioning of the guide unit inside the rail is guaranteed. In addition, the invention provides for the maximum safety even for other road users (pedestrians, cyclists, vehicles in general and animals) where the transport system described in the present patent is installed. A further object of the present invention is that the system ensures maximum safety for passengers on board and for people in the vicinity of the vehicle, since it is impossible for the vehicle to derail and/or overturn.

One advantage of the present invention is that it does not involve polluting or acoustic emissions while the vehicles are in use as they are equipped with electric motors.

Another advantage of the present invention is that the vehicles may also be used by those without a motor vehicle driver's license, by elderly people, and disabled people in general.

A further advantage of the present invention is that each vehicle allows intermediate stops which are independently and selectively decided by the vehicle user.

Still another advantage is that it enables low energy consumption mobility due to the reduced dimensions and weights of the vehicles as well as energy recovery devices during braking.

These and other aims, direct and complementary, are achieved by the new transportation system for people and/or things, which uses electric vehicles that travel constrained to rails.

The new transportation system comprises a rail system and at least one circulating vehicle constrained to the rails.

Each vehicle comprises a structure supported by wheels and is preferably small in size, designed to carry things and/or one or more persons, but preferably up to four or five people. For example, the vehicle is a shuttle, with two seats preferably aligned in the forward direction and, for example, facing each other.

Each vehicle is equipped with control means operable by the user of the vehicle itself, with which he/she can start the vehicle, stop the vehicle, decide the route in correspondence with the exchanges, and activate optionals such as acoustic or light signals.

The vehicle is not driven by the user, since the vehicle is constrained to follow the rail along the required route, which is preferably a closed circuit or "loop". The control means on board the vehicle comprise, for example, and advantageously a "touch screen" by which the user can start and stop the vehicle, choose the route and the stop at which to get off, and activate any optionals. The touch screen can also be used to signal emergencies and provide technical and tourist information to the user. The vehicles are equipped with speed limiters, to ensure the exact same safety speed for all vehicles. For example, the maximum speed allowed is 10-20 Km/h.

Each vehicle is equipped with a control system by means of which the vehicle itself is automatically slowed down or stopped when approaching an obstacle or a second vehicle or when it encounters a vehicle at a switching point, so as to always ensure the maintenance of a minimum safety distance between vehicles.

This control system includes, for example and advantageously, sensors placed on the front and on the rear of the vehicle, suited to cause the vehicle to stop in the event that an obstacle is detected.

It is also possible for the control system to, in an emergency situation or to perform the retrieval of the vehicle, automatically activate the vehicle, which, without a driver, is returned to a pre- established station.

Each vehicle is preferably equipped with at least one electric drive motor with batteries, which can be advantageously recharged in special charging stations.

At least two of the wheels, or drive wheels, are equipped with their own electric motor.

It is also possible for each of these vehicles to be equipped with a photovoltaic panel, positioned, for example, on the roof of the vehicle, able to produce electricity with which the batteries cab be recharged.

The vehicle is therefore electrically powered autonomously and can also circulate only on the special rails.

In the preferred embodiment, the vehicle comprises four wheels, preferably made of pneumatic rubber which leads to a reduction in noise and vibrations due to the road surface.

The rails are preferably and advantageously formed of modular segments and are completely embedded in the road surface.

The various rail segments are joined together by means of connection and expansion joints, for example made of plastic.

In the preferred embodiment, the system is monorail. Each of the modular segments which comprise the entire rail has a box section, that is, comprising a lower wall or base, two lateral walls, and an upper wall with a longitudinal groove along its overall length. The inside of this rail defines the guide in which part of at least one guide unit constrained to the vehicle and inserted in the groove slides.

To ensure the stability of the guide unit in the roadway, the rail rests on a beam housed in the roadway, for example and advantageously an IPE type.

Special drain points are also provided for on this rail, for the outflow of any rainwater or wash water that might enter the rail. These drains are suitably connected by means of drainage ducts to collection and removal pits.

These vehicles are therefore constrained to move only along the rails and only in one direction, or forward direction, while circulation in the opposite direction is preferably prevented or permitted only for small sections, for example for manoeuvring and emergency operations.

The circuit along which each vehicle is constrained to circulate is suitably a closed circuit or "loop".

The at least one guide unit suited to be partially housed in the guide of the rail through the longitudinal groove made on the rail itself is mounted under the vehicle structure.

In the preferred embodiment, the guide unit and guide unit support or shank are structured and sized so as to slide substantially flush with the side walls of the guide, and possibly, directly or indirectly, against the inner face of the upper guide wall, thus always remaining raised compared to the base of the rail.

In one possible embodiment, the at least one guide unit comprises in turn a support or shank suited to be inserted in the groove, at the end of which at least one main bearing or roller is constrained, with a vertical rotation axis, and suited to slide in a main guide inside the rail. This main guide is advantageously made up of the vertical side walls of the rail.

Preferably, the guide system comprises two of the main bearings or rollers which are placed one on top of the other and which slide in the main guide.

The guide unit may also preferably comprise a secondary bearing or roller, with a vertical rotation axis, suitably placed at a lower level with respect to the main roller and preferably having a rotation axis coinciding with the rotation axis of the main roller.

This secondary roller is suited to slide inside a secondary guide inside the guide, for example made of a pair of vertical partitions facing each other. This secondary roller is joined to the main roller by an extensible shaft, where in one configuration, for example extended, the secondary roller is placed inside the secondary guide, while in a second configuration, for example contracted, the roller is placed outside of this secondary guide.

The function of said secondary roller and of said extensible shaft is to allow the course of the vehicle to be selected at the level of a set of switching points on the rail.

For example, in the case where the rail divides into two branches with different directions, at the junction, at least one secondary guide may be created inside the guide which continues only in one of the two branches.

By varying the position of the secondary bearing or roller, if it engages in the secondary guide, the vehicle will be guided towards the corresponding branch, otherwise, if the bearing remains outside the secondary guide, the vehicle will be guided towards the other branch.

The configuration of the shaft, which may advantageously comprise an electro-piston, is regulated from inside the vehicle.

Alternatively or in combination with the secondary bearing or roller, a switching point may be mounted at the junction, that is, an element hinged to the rail upstream of the junction and suited to rotate in such a way as to selectively block the opening of one of the two branches of the junction. In one possible embodiment, the vehicle is also advantageously equipped with a steering system with electromechanical actuators electronically controlled according to the signals concerning the route of the rail to be followed.

In particular, along the rail a plurality of electronic devices may be distributed suited to communicate with the control system on board the vehicle. These electronic devices, which may for example be transmitters or transponders, communicate the route to be followed to the vehicle's electronic system, and that electronic system consequently commands the steering system, according to the curvature of the route to be followed and the current speed of the vehicle.

In the preferred embodiment, these transmitters or transponders are installed inside the rail, and are of the passive type, suited to communicate the data relating to their position when they are queried by a corresponding electronic device or transponder installed on the guide unit. When the vehicle's guide unit passes near the transponder installed in the rail, the rail is queried by the transponder installed on the guide unit and responds with the data relating to its position so that the on-board computer or the control system in the vehicle calculates, depending on the transponder detected, the operations to be performed such as: turning, stopping, slowing down, restarting, etc. The control is in fact to be considered for all intents and purposes of the intelligent type which communicates continuously and in real time the exact position of the vehicle to the vehicle's on-board computer.

The vehicle's guide unit may also comprise at least one brush, also housed inside the groove in a position preferably ahead of the bearings in the forward direction along the rail, this brush being suited to keep the inside of the rail clean.

To limit the risk that the vehicle encounters foreign objects such as debris or stones on the ground along the rail, under the vehicle one or more brushes may be installed, mounted at least at the front of the vehicle, in correspondence with the guide unit, so that any debris close to the rail will be swept away before making contact with the guide unit.

Furthermore between the structure and the guide unit at least one intermediate joint may be mounted, with double hinges and with elastic means where needed, and where, in the case in which the vehicle encounters small obstacles such as stones, holes or debris in general, the joint and the spring allow the obstacle to be overcome, by preventing the bearings from locking.

The guide unit may also comprise one or more internal anti-lifting wheels or rollers, intended to be housed and to slide inside the rail, in a displaced position with respect to the groove, so that the guide unit is prevented from accidentally coming out of the groove.

The internal anti -lifting wheels or rollers are preferably kept sliding against the inner face of the upper wall of the rail, at the sides of the longitudinal opening, by elastic means, such as thrust springs, to ensure the proper positioning of the guide unit with respect to the rail.

To allow the guide unit to be extracted from the rail and consequently release the vehicle from the rail itself, inspection strips equipped with a removable upper plate on the rail itself are provided in order to remove the sliding restraining device of each vehicle.

As an alternative to these inspection strips, the upper wall of the rail may be mounted in a modular and removable way, so as to make the entire rail accessible from above, and thus facilitate any maintenance and/or cleaning interventions. The various segments of the upper wall are joined by special expansion joints in such a way as to allow the inevitable thermal expansions of the rail.

Moreover, in correspondence with a switching point, the rail comprises a sensor suited to signal to the vehicle the possibility of rerouting from the main route by means of devices on board operated by the user.

The new system is particularly suitable for tourist resorts, parks or tourist villages, in limited or controlled circulation environments, such as car parks or adjacent areas of airports, stadiums, etc., pedestrian areas, hospitals, etc.

The rails can either be on existing roads or cycle paths, or on dedicated roads and thanks to their ground level positioning, without depressions and with only one small groove, they do not constitute an obstacle or risk for other road users, such as pedestrians and cyclists.

The system also preferably and advantageously includes a plurality of charging stations, in which it is possible to electrically connect the batteries present on each vehicle to a recharging unit, also by induction.

The closed circuit or loop in which the vehicles circulate advantageously comprises one or more sidings or spurs from the main closed circuit, to reach the recharging stations or to stop stations, for users to get in/out of the vehicles.

Each vehicle may be selectively configurable for access by a wheelchair as it is free of architectural barriers.

In the preferred embodiment a single rail is provided completely embedded in the sliding plane, where the upper surface of the rail itself is flush with the sliding plane, leaving only a small slot, of dimensions comparable to a slot in a rain water drain, for the sliding of the constraint shank.

In one possible embodiment, the rail of the new transportation system comprises a system for closing the longitudinal groove of the rail by means of movable partitions, so as to achieve the following results:

-the introduction of dirt and debris in general inside the rail is prevented or minimized;

-the shank of the guide unit is kept in a vertical position;

-the shank of the guide unit is kept at a distance from the edges of the longitudinal groove, so it does not scrape against the metal material of the rail but rather against the suitable material with which the mobile partitions are made;

-the risk of the accidental introduction of objects or parts of different vehicles circulating on the same road level is prevented or minimized;

-the closure is hermetic, thus creating within the rail a sort of closed conduit that facilitates the washing of the inside of the rail. The adoption of this closure system also prevents the possible or accidental access by hands, fingers, animal paws, and any foreign bodies.

In particular, this closure system comprises at least one or preferably a pair of opposed partitions, arranged longitudinally in proximity to the longitudinal groove of the rail, and where these partitions are maintained by elastic means in a position such as to close the longitudinal groove. These partitions are deformable only in the longitudinal direction, so as to adapt to the passage of the guide unit shank inserted in the rail, and then return to the tight and rest configuration.

These partitions are shaped so as to provide tightness.

These partitions are moreover symmetrically arranged with respect to the longitudinal groove, so as to keep said guide unit shank in a substantially central position in the longitudinal groove, preventing it from scraping against the upper wall of the rail, and in such a way as to maintain the shank in a substantially vertical position while sliding.

The rail is furthermore specially shaped so that the partitions are constrained to only adapt or slide horizontally, while the sliding in a vertical direction is prevented.

The partitions may also be distributed along the entire length of the rail and each partition is joined to the consecutive partition, for example by interlocking or fixing means, preferably in a removable manner.

The characteristics of the new system will be better clarified by the following description with reference to the drawings, attached by way of a non-limiting example.

Figure 11 shows a charging station (10).

The new transportation system comprises a rail system (2) and at least one vehicle (1) circulating on said rails (2).

Each vehicle (1), shown for example in Figure 1, comprises a structure (11) supported by wheels (81, 82), for example and preferably four wheels, two of which are front (81) and two rear (82) wheels. In the example in Figure 1, the vehicle (1) is a two-seater shuttle, with the seats preferably aligned in the forward direction (X).

At least two of the wheels, or drive wheels, have their own electric motor, where each wheel is powered independently of the other.

In one possible embodiment, shown in Figure 10, the drive wheels are the rear wheels (82). Each of the vehicles (1) may also be equipped with a photovoltaic panel (12), positioned for example on the roof of the vehicle, able to produce electrical energy with which to recharge the batteries. These rails (2) are preferably and suitably made up of modular segments and are completely embedded in the road surface.

In the preferred embodiment, the system is monorail. Each of the modular segments which comprise the entire rail (2) has a box section, that is, as shown in Figure 4, comprising a lower wall or base (21), two lateral walls (22) opposite each other and an upper wall (23) on which a longitudinal groove (24) is made along its overall length.

The inside of the rail (2) defines the guide (25) in which part of at least one guide unit (3) constrained to the vehicle (1) and inserted in the groove (24) slides.

This guide unit (3) is suitably constrained near the front part of the vehicle (1) for example in a position slightly behind the front wheels (81) of the vehicle (1).

To ensure the stability of the rail (2) in the roadway, it rests on a beam (4) housed in the roadway, for example and advantageously an IPE type.

Below the structure (11) of the vehicle (1), the at least one guide system (3) is mounted, which in turn comprises a support or shank (33) suited to be inserted in the groove (24) of the rail (2).

In the embodiment in Figure 10, the shank (33) is shaped with an enlargement (331) at one end, suitable for sliding inside the rail (2).

In the embodiment in Figures 1 to 7b, the guide system (3) comprises, at the end of the shank (33), at least one main bearing or roller (31), with a vertical rotation axis (Y), suited to slide in a main guide (25) within the rail (2). This main guide is for example made up of the vertical side walls (22) of the rail (2).

Preferably, the guide system (3) comprises two of the main bearings or rollers (31) placed one on top of the other and which slide in the main guide (25).

In the embodiment shown in Figure 5, the guide system (3) also preferably comprises a secondary bearing or roller (32), with a vertical rotation axis (Y), suitably placed at a lower level with respect to the main bearing of roller (31) and preferably having an axis of rotation (Y) coinciding with the rotation axis of the main roller (31). This secondary roller (32) is suited to slide inside a secondary guide (5) inside the rail (2), for example made of a pair of vertical partitions (51, 52) facing each other.

This secondary roller (32) is joined to the main roller (31) and to the shank (33) by means of an extensible shaft (34), where in one configuration, for example extended, shown in Figure 5, the secondary roller (32) is located inside the secondary guide (5), while in a second configuration, for example contracted, shown in Figure 6, the secondary roller (32) is located outside the secondary guide (5).

As shown in Figure 6, in the case in which the rail (2) divides into two branches (2a, 2b), the secondary guide (5) may be constructed at the junction (20) and in one of the two branches (2b), so that, by varying the position of the secondary roller (32), if it engages in the secondary guide (5), the vehicle will be guided towards the corresponding branch (2b), otherwise, if the secondary roller (32) remains outside the secondary guide (5), the vehicle will be guided towards the other branch (2a). Alternatively or in combination with the secondary bearing or roller (32) slideable in the secondary guide (5), a switching point (200) may be provided for at the junction (20), hinged to the upper part (23) of the rail (2) at a point (210) upstream of the junction (20) and suited to rotate in a guide (220) so as to selectively block the opening of one of the two branches (2a, 2b) of the junction (20).

In the embodiment shown in Figures 7 and 7a, the guide system (3) also comprises at least one brush (6), also housed inside the rail (2) in a position in front of the main rollers (31) in the forward direction (X) along the rail (2), this brush (6) being able to keep the inside of the rail (2) clean.

As shown in Figures 7 and 8, the vehicle (1) also comprises one or more brushes (9) mounted on the front part of the vehicle (1), useful for sweeping away any debris close to the rail (2).

Figure 5 also shows how the guide system (3) may be mounted on the structure (11) of the vehicle (1) by means of at least one intermediate joint (35), with a double hinge and elastic means.

The guide system (3) may also comprise one or more internal anti-lift wheels or rollers (7), intended to be housed and to slide inside the rail (2), against the inner face of the upper wall (23) of the rail (2) itself and with a horizontal rotation axis (XI), in an offset position with respect to the groove (24), so that the sliding guide system cannot accidentally come out of the rail (2).

Small teeth (71) may be present on the upper wall (23) of the rail (2) to guide and contain the anti-lift wheels or rollers (7) suited to prevent the guide system from coming off.

The vehicle (1) also includes a steering system, which allows the vehicle (1) to follow the route of the rail (2).

In the embodiment in Figure 10, as noted, the rear wheels (82) are driven, while the front wheels (81) are suitably pivoting, and where along the longitudinal axis of the vehicle (1), in proximity to the front wheels (81) the guide system (3) is mounted, which, sliding inside the rail (2), guides the vehicle's (1) course.

Alternatively, each of the two front wheels (81) may be equipped with a dedicated electric motor and a steering system suited to control the speed of each of the electric motors of the two front drive wheels (81), so as to establish the relative speed between the front wheels (81) themselves.

In particular, along the rail (2) a plurality of electronic devices may be distributed which communicate with the control system or on-board computer of the vehicle (1).

These electronic devices transmit to the control system the data relating to the current position and the route of the rail (2) and, according to the data received, the control system manages the operational parameters of the motors.

For example, the on-board control system of the vehicle (1) changes the absolute and/or relative speed of the drive wheels (81) according to the curvature of the route that the vehicle (1) must follow and according to the current speed of the vehicle (1).

In particular, the electronic devices may be distributed on the rail (2), and advantageously along the rail's curves (2).

In the preferred embodiment, at least one of the electronic devices may be installed on the rail before the beginning of each curve, and is programmed to transmit the data relating to the curve itself, so that the control system, according to the data received from the nth electronic device and the current speed of the vehicle (1), regulates the relative speed of the front drive wheels (81), thus controlling the vehicle's course (1).

The control system, near or at the entrance of a curve, may also regulate the vehicle's (1) forward speed, setting it to a predetermined value to manage the curve.

In the preferred embodiment the route will be a closed circuit type, with possible deviations for recharging and storage points.

Figure 11 shows a charging station (10) according to one embodiment, where it is shown how the closed main circuit of the rails (2) comprises one or more deviations (2') for the vehicles to go to one or more charging stations (10).

The charging station (10) comprises, for example, one or more photovoltaic panels (101) connected to an induction charging device (103) mounted on the deviation (2'), so as to make electrical contact with the vehicle (1).

The charging station (10) also preferably comprises devices (102) to activate the recharge, which may require for example the payment of the service, as well as any signalling devices (104) or indicators that inform the user about the operating status of the charging station (10).

Figures 12 to 21 show a preferred embodiment for making a system to close the longitudinal groove (24) of the rail (2).

In particular, in Figure 12 a cross-section of the rail (2) is shown with closure partitions (91, 92) in a closed configuration, that is, arranged opposite each other so as to hermetically close the groove (24) of the rail (2).

Figure 13 shows the same section of Figure 12 with closure partitions (91, 92) shifted laterally during the passage of the shank (33) of the guide system (3).

Figure 14 shows a cross section of the rail (2) in an alternative embodiment, with the closure partitions (910, 920) shifted laterally during the passage of the shank (33) of the guide system (3). Fi gure 15 shows a detail of the closure partitions (910, 920) in the embodiment in Figure 14, in a closed configuration.

Figure 16 shows a top view of a detail of the rail (2), where the longitudinal groove (24) is visible, the closure partitions (91, 92) shifted outwardly during the passage of the shank (33), shown in section.

Fi gures 17 and 18 show a sectional and three-dimensional view of the shank (30) in an alternative embodiment, comprising lateral sliding bearings (301).

Figures 19, 20 and 21 respectively show a side view, a plan view and a three-dimensional view from below of the closure partitions system (91, 92), where it is possible to foresee the installation of a pair of shaped flanges or walls (98), specularly arranged between the two closure partitions (91, 92) and serving as a tapered slot for the sliding of the shank (33) between two consecutive pairs of closure partitions (91, 92), in order to avoid the risk of the shank (33) being blocked.

Figure 22 shows a top view of the rail, with closing partitions (91, 92) and expansion joints (900). The rail (2) of the new transportation system comprises a closure system for the longitudinal groove (24) of the rail (2).

This closure system comprises at least one or preferably, as shown in the figures, a pair of opposing closure partitions (91, 92), arranged longitudinally in proximity to the longitudinal groove (24) of the rail, and where the closing partitions (91, 92) are maintained by elastic means (94) in a position such as to close the longitudinal groove.

In the embodiment with two partitions (91, 92), the elastic means (94) keep the opposing partitions (91, 92) against one another, so as to hermetically seal the groove (24).

These closure partitions are adaptable and moveable only in a horizontal and transverse direction with respect to the length of the rail (2) and the longitudinal groove (24), so as to deform outwardly during the passage of the guide system's shank (33) inserted in the rail (2) as shown in Figure 13 and then return to the closed position.

The partitions may be formed, for example, with edges (97) shaped in such a way as to create a hermetic seal when pressed against each other, as shown in Figure 12.

These closure partitions (91, 92) are moreover symmetrically arranged with respect to the longitudinal groove (24), so as to keep the shank (33) of the guide system (3) in a substantially central position in the longitudinal groove (24), preventing it from scraping against the upper wall (23) of the rail (2).

Moreover, the presence of these closing partitions (91, 92) keeps the shank (33) in a substantially vertical position while sliding.

In the embodiment shown in Figures 12 and 13, the upper wall (23) of the rail (2) is made up of two opposing seats (231, 232) where the closure partitions (91, 92) are constrained to move only laterally between the closed configuration (Figure 12) and the shifted open configuration (Figure 13). The vertical displacement of the partitions (91, 92) is prevented. Between the walls of the seats (231, 232) and the partitions (91, 92) the elastic means (94) to push the partitions (91, 92) against each other are also interposed.

These seats (231, 232) are defined by walls comprising at least one small tooth (233) facing downwards to serve as a block for the sliding of each partition (91, 92) towards the opposite partition, wherein the partitions (91, 92) are correspondingly shaped with a recess (96) suited to come into contact with the small tooth (233) of the relative sliding seat (231, 232).

In the embodiment shown in Figure 15, the seats (231, 232) are shaped differently, but the essential concept does not change.

The partitions (91, 92), with a modular length, may be distributed along the entire rail (2) and each partition may be joined to the following partition, for example by means of interlocking or fixing means, preferably in a removable manner.

Alternatively, the embodiment may comprise flanges serving as a tapered slot (98) shown in Figures 19, 20 and 21.

Therefore, with reference to the preceding description and the attached drawings the following claims are made.
