E. DETAILED DESCRIPTION OF DRAWINGS

[0091] With reference to FIG. 1, there is illustrated a General Plan View of a part of a Train Station platform (02), with the Passengers Train (04) stopped at a Platform (02).

[0092] The Platform (02) has provisions for Boarding Assistance Zones (03).

[0093] A Disabled Person on a Wheelchair (07) is shown approaching the Boarding Assistance Zone (03), with the intention to gain access to the Passengers Train (04).

[0094] The Boarding Assistance Zone (03) is provided to receive a Descending Mechanised Access Ramp (D-MAR) (01) described below.

[0095] With reference to FIG. 2, there is illustrated a Plan View of the Platform (02) with more details of the Boarding Assistance Zone (03) provided to receive a D-MAR (01).

[0096] With reference to FIGS. 3 to 14, the Descending Mechanised Access Ramp (D-MAR) system is exemplified including a substantially planar casing box (12) which is mountable to or embedded within the floor of the train (09) and a hinged jointed sliding ramp (10) which is installed inside the substantially planar casing box (12). The hinged jointed sliding ramp (10) further includes a plurality of side wheels (11) which are adapted to allow the hinged jointed sliding ramp (10) to be slidably moveable inside the substantially planar casing box (12). A remote controlled deployment mechanism (not shown) is configured to automatically deploy the hinged jointed sliding ramp (10) between a stand-by position (as shown in FIG. 03) to a fully deployed position (as shown in FIG. 08). There is provided at least two mobile protection walls (35) which are positioned on the station platform (02). The at least two mobile protection walls (35) further include tactile push buttons (13) that are adapted to trigger flashing lights (06) installed on top of the at least two mobile protection walls (35) to activate the remote controlled deployment mechanism of the D-MAR.

[0097] A Mobile Protection Wall (35), comprise a Handrail (19), at least one Bollard (36) and a Wheelchair Kerb (37) is installed on each side of the Boarding Assistance Zone (03), in order to facilitate the access of Disabled Persons on Wheelchairs (07) to the Train (04) and to provide maximum protection to all commuters while using the D-MAR (01).

[0098] At least two Safety Bollards (05) are also installed on each side of the Boarding Assistance Zone (03), bolted on the Platform (02), in order to localise and in the same time to operate the D-MAR (01).

[0099] Signage and other Wayfinding facilities will be customised on each train station, in conjunction with Stakeholders' requirements, in order to localise the Boarding Assistance Zones (03).

F. D-MAR OPERATING SYSTEM

[0141] The D-MAR (01) is installed (bolted) on the Train Floor (09), during the train manufacturing process. Alternatively, the D-MAR (10) may be embedded within the train floor. In either case, an upper surface of the Casing Box (12) is flush with the floor of the train.

[0142] Alternatively, the D-MAR (01) can also be retrofitted to existing trains. In this case Small Mounted Ramps shall be installed on the sides of the D-MAR (01), to facilitate the access of wheelchairs and prams.

[0143] A Disabled Person in Wheelchair (07) arrives on the Station Platform (02) at the Boarding Assistance Zone (03) with the intention to use the D-MAR (01) to embark to the Train Floor (09), (FIGS. 01 and 02).

[0144] The Disabled Person (07) press the Tactile Push Buttons (13) on the Safety Bollards (05), which will trigger the Flashing Lights (06) and announce the train driver the request to use the D-MAR (01).

[0145] The Disabled Person on Wheelchair (07) will place themself in the Boarding Assistance Zone (03).

[0146] The D-MAR (01) can be also activated from the train by pressing the Tactile Push Buttons (14) in the Passenger Train (04).

[0147] The D-MAR (01) can be also activated by the train driver.

[0148] The D-MAR (01) can be also activated by the train guard.

[0149] The vehicle-based D-MAR activation system communicates with the platform-based system via a wireless protocol. When the wireless system is in range (such as within a few millimetres, centimetres, feet or metres) the vehicle and platform-based D-MAR components will begin communication.

[0150] If either the vehicle or platform tactile push buttons are activated, all visual activation points (Flashing Lights (06) and train driver indicator) will activate when the wireless system begins communicating. The flashing light will take the form of high intensity LED lights or incandescent lighting arrangements.

[0151] The train driver will recognise the Flashing Lights (06) and will try to stop the train as close as possible to the Car Stop mark, to ensure the D-MAR (01) is aligned with the Boarding Assistance Zone (03), (see FIG. 3).

[0152] As soon as the train doors will be completely open, the operating system of the D-MAR (01) is automatically activated. The activation of the D-MAR (01) may be controlled or triggered by the same mechanism that controls the train doors.

[0153] The D-MAR (01) can be configured to commence deployment autonomously or manually from the train driver control panel or by platform staff.

[0154] The Sliding Ramp (10) is deployed in several phases, as described on FIGS. 04, 05, 06, 07 and 08.

[0155] When the Sliding Ramp (10) is fully deployed, the two Mobile Protection Walls (35) will get tied up against the Sliding Ramp (10), in order to provide a safe embarkment to the train.

[0156] Optical and Proximity Sensors (21) on the Nose (08) of the Sliding Ramp (10) and Optical and Proximity Sensors (20) on the Train Floor (09) can be used to control the deployment of the Sliding Ramp (10).

[0157] The full deployment of the Sliding Ramp (10) takes approximately 7 seconds.

[0158] The D-MAR (01) can be now used by Disabled Persons on Wheelchairs (07) or persons with reduced mobility (see FIG. 09). The D-MAR (01) can be also used by persons with prams/strollers. The D-MAR (01) can be also used by persons with large luggage.

[0159] When the commuters' embarking and disembarking the train are completed, the return to the “stand-by” position of the Sliding Ramp (10) can be activated by: [0160] any person on the platform, by pressing the Tactile Push Buttons (13) on the Safety Bollards (05) or [0161] any person in the train, by pressing the Tactile Push Buttons (14) or [0162] the train guard or [0163] the train driver.

[0164] At this moment the two Mobile Protection Walls (35) will move away from the Sliding Ramp (10), up to their stand-by position.

[0165] The Sliding Ramp (10) will then return to the stand-by position, inside the train.

[0166] The entire cycle of the return of the Sliding Ramp (10) to the “stand-by” position will take approximately 7 seconds (see FIG. 10).

[0167] The train doors can be closed only after the Sliding Ramp (10) is fully retracted on stand-by position.

[0168] A similar process is used to activate the D-MAR from the train: the Disabled Person on Wheelchair (07) is pressing the Tactile Push Button in the Train (14) and the D-MAR (01) is deployed as previously described (see FIGS. 11, 12, 13 and 14).

L. SIXTH PREFERRED EMBODIMENT

[0184] With reference to the FIGS. 15 to 26, applicable to all Embodiments, the D-MAR (01) can retrofit the existing trains. A Small Mounted Ramps will be installed around the Casing Box (12), in order to facilitate the access of the wheelchairs or prams.

M. SEVENTH PREFERRED EMBODIMENT

[0185] In an alternative embodiment, there is provided a system for providing access to a vehicle (which in the figures is shown as a train). The train (4) has at least two opposing entry/exit points as is exemplified in FIGS. 15 to 26. A slidable hingeable ramp (10) is positioned between the two opposing entry/exit points of the train as is shown in FIG. 15. The two entry/exit points represent opposing doors of a train carriage. The system includes a mechanism adapted for operation of the slidable ramp in at least a plurality of configurations. The mechanism may take the form of a Rack and Pinion (FIG. 21, 22, 23 Parts 30, 31) mechanism, a Teeth Belt or Chain and Pulley System or a Scissors and Jack System as were previously discussed. The plurality of configurations includes at least: [0186] i. a standby configuration (as shown in FIG. 16), wherein the slidable ramp is substantially positioned between the at least two opposing entry/exit points; [0187] ii. a first entry/exit configuration (as shown in FIG. 17), wherein the slidable ramp is extended outside one of the at least two opposing entry/exit points to a first surface external to the vehicle (e.g. first station platform); and [0188] iii. a second entry/exit position (as shown in FIG. 19), wherein the slidable ramp is extended outside an opposing entry/exit point to a second surface external to the vehicle (e.g. second station platform).

N. OPERATION IN USE

[0189] With reference to FIGS. 03 to 10, in one embodiment, a disabled person in a wheelchair (7) approaches an incoming passenger train (4) as is shown in FIG. 03. The disabled person in the wheelchair (7) notifies the train of their intention to board the incoming passenger train (4) by pressing the tactile push button (13) which is located on safety bollards (5) on the platform (2) of the train station. This action communicates wirelessly with the train (4), when the train is in range, the intention of the disabled person (7) to board the train and subsequently initiates the deployment process of extending a sliding ramp (10) onto the platform (2) to assist the disabled person to enter the train (4).

[0190] The pressing of the tactile push button (13) initiates wireless communication between the safety bollards (5) and the train (4) to initiate the action of extending the ramp onto the station platform (2) once the train door has aligned with the safety bollards (5) on the station platform (2). The deployment may be triggered or synchronised with the opening of doors of the train. This deployment action may be assisted using one or more optical and/or proximity sensors that are installed on the passenger train (4) and the nose (8) of the sliding ramp (10). The train door opens and the sliding ramp (10) extends onto the platform as is exemplified in FIGS. 04 to 08. As the sliding ramp (10) extends it slides along the platform allowing the disabled person (7) to enter the train up the safety ramp. Once the disabled person (7) has entered the train, the sliding ramp (10) is then remotely controlled by an operator using tactile push buttons located in the train (14) to retract the sliding ramp (10) back into the train (4) to allow the train doors to close.

O. GENERAL NOTES

[0191] The Sliding Ramp (10) is preferably made from an electrically non-conductive composite material, with a minimum weight and with the required structural strength.

[0192] The Sliding Ramp (10) has the adequate number of Side Wheels (11), to enable skating inside the Casing Box (12) and provide access to each side of the train.

[0193] The surface of the Sliding Ramp (10) is preferably covered with a non-slippery coating. The non-slip coating may consist of a rubberised paint or a textured surface providing additional grip for a person using the Sliding Ramp (10).

[0194] The D-MAR (01) is built using standard materials and equipment, approved composite and electrical non-conductive components, in accordance with rail industry, safety Standards and requirements.

[0195] Deployment of all mechanical components will be controlled through a microprocessor-based electrical system which will be housed within a dedicated enclosure. Standard deployment of the system will be through timing and events-based triggering, managed by the microprocessor.

[0196] All mechanical movement of the ramp deployment will be tracked and controlled through optical and proximity sensor feedback to the microprocessor. Hard limit switches will be used to detect when the ramp has reached predetermined limits for fail-safe systems.

[0197] Embodiments of the D-MAR can be installed in relatively short timeframes and at costs generally lower than existing solutions.

[0198] The D-MAR can be easily relocated, replaced or simply removed, with minimum remediation works.

[0199] The D-MAR will be custom designed to satisfy the general Standard obligations and the Stakeholders' requirements, to fulfil the function of the ramp, to satisfy any train access requirement or any loading capacity.
