Abstract

Lifting platform to allow accessibility of people with reduced mobility to trains. Lift platform housed under the floor of the train car, which allows people with reduced mobility to access the train car, eliminating the existing architectural barrier. It consists of three distinct parts: the tertiary base (elements from -8- to -13-), responsible for joining the rest of the platform components with the structure of the train car and providing the necessary vertical movement, the secondary base ( elements from -14- to -19-) that makes the link between the primary and tertiary base, and provides horizontal movement, and the primary base, part where the platform user is housed (elements from -20- to -29 -) when it is raised from the platform to the wagon floor, or on the contrary, when it is attached from the car to the platform. The platform adapts to the different levels that are on the platforms of the stations and can work with a drop in energy in the train, since all the components that generate enough power to perform the movements (servomotors and pneumatic pistons) can be manually operated

Description

Lifting platform to allow accessibility of people with reduced mobility to trains.

Technical sector

The present invention relates to a lifting platform for people with reduced mobility, located in train cars, which achieves notable improvements in autonomy and accessibility for users with these features to the train car, as well as improvements in terms of at maneuver time, space required, system reliability (to be able to operate in case of train breakdown) and the important fact that the user does not need the collaboration of a third party person to help you access the car or get off the car to the platform.

State of the art

Different mechanisms are known that allow for people with reduced mobility access the means of public transport, including trains.

So far, these mechanisms require a third person to execute the movement cycle of the mechanism, require a high maneuver time, or occupy a  useful space in the car, minimizing transport capacity of the same. In addition, most of them do not work in case The train has a power supply breakdown.

In addition to this, existing systems vary access to the train car to other users.

Explanation of the invention.

This invention consists of a platform lift that will pick up the person with reduced mobility in the station platform and will lift it to the floor of the train car, and vice versa, when the user wants to get off at the station desired.

What distinguishes it from those mentioned in the state of the art is that first of all for the execution of the movements will not be necessary the intervention of any third person, in addition to the user and the driver of the convoy of the train, since the one that will put it into operation will be the driver from his usual place without having to move to the place  where the ramp is (gaining autonomy for the user, and minimizing the execution time, being therefore less time the train stopped at the corresponding station).

In addition, the ramp will be housed below ground. of the wagon, not eliminating passenger transport capacity in the wagon, and given the characteristics of its movements, allows absorb the differences in dimensions that may appear, from the different heights of the floors of the station platforms, until the wear of the train wheels.

To avoid the inconveniences presented in these platforms today, the new design has the following fundamental characteristics:

-

Do not you need a third person for the operation of the platform, since it will be the convoy driver himself who start the movement cycle from your cabin in case the user is on the platform, or the user himself in the event that he be in the train car and want to get off at a stop determined also gaining execution time of the maneuver of this way.

-

To the be housed under the floor of the car, nor reduce the capacity of the same as for the number of passengers nor does access to the car vary of the train to users without reduced mobility, and in turn, to being hidden in the car, minimizes the possibility of acts vandalism

Description of the invention

The present invention consists of three parts, each of which must assume a cycle of movements own.

The first part is the so-called tertiary base. This tertiary base has two functions:

-

Link the elements of the platform to the structure of the wagon of train.

-

Provide vertical movement necessary to the secondary and primary bases, to upload the user from the station platform to the wagon, and vice versa, when the User wants to get out.

This tertiary base is fixed to the structure of the train car by its bottom and vertical movement It will be done by four sliding guides - two per side - two re-shipments -one by side- that will transmit the generated power of an electromechanical elevator. The slides they will be fixed to the secondary base, while the guides corresponding are fixed elements of the tertiary base.

This elevator allows its operation in a way manual in case of a power drop.

The second part is the so-called secondary base. This secondary base has two functions:

-

Link the elements of the tertiary base and primary base.

-

Provide horizontal movement necessary, so that the primary base, which is where the user, exit or enter inside the bottom of the car towards the platform.

The union between the tertiary and secondary base is performed using the vertical sliding guides above described. In turn, the union between the secondary and primary base is It also performs using other horizontal sliding guides.

Just like vertical scrolling, The horizontal translation will be provided by a servomotor.

The last part of the invention is about the primary base. It is the element that will go outside the car of the train and whose function will be to directly support the user.

Given the reduced dimensions of the space available from under the floor of the wagon where the platform, as well as safety dimensions and conditions required by regulations to lifting platforms for people with reduced mobility, the primary base consists of two parts, joined together by sliding guides, allowing a deployment horizontal between both parties. To perform this deployment, you they use two pneumatic cylinders, one on each side of the base primary.

Each of the parts of the primary base has, both to facilitate user access and to provide a safety stop, two ramps that will be pneumatically operated. The outer ramp is the one that will contact the platform, and the inner ramp is the one that will land on the floor of the carriage
train.

Exhibition of an embodiment

The first necessary move will be a transverse movement of the platform to the outside of the car of the train (figure 1.1), that is, towards the station platform, where the person with reduced mobility will be located.

This movement will be provided by the base secondary described in Figure 8, by means of a servomotor (14), a forwarding (15) and sliding guides (17).

Once the platform is out of inside the car, the next move will be a vertical one descending until the platform contacts the platform floor (figure 1.2).

To perform this movement, the base will act tertiary shown in figure 7 by its servomotor (8), re-shipment (9) and guides (10).

Once in contact with the ground, it will be deployed the primary base ramp (figure 12), using energy provided by two pneumatic pistons (28 and 29).

Then the user will already be in willingness to access the platform (figure 1.3).

The next move (once the primary base ramp), will consist of a user elevation from the platform floor to the height of the train car (figure 1.4).

It must be said that all these movements are will perform with the greatest precision, since the platform is equipped with the necessary sensors to execute the cycle of movements in a fully controlled manner, giving maximum security, allowing in turn to absorb the differences in dimensions existing in the different platforms of the stations.

Thus, once the user is located at the wagon height, you can access it without difficulty (figure 1.5), once you have lowered the ramp (25) shown in the figure 12.

Once the user has accessed inside of the train, the collection of the platform will take place so that stay under the floor of the car in your situation repose. Therefore, in the first place a movement will be made descending the platform to the initial level (figure 1.6).

The last movement will be a translation horizontal that allows the platform to re-enter the inside of the car (figure 1.7).

As previously mentioned, in the Figures 13 and 14 are described in detail by a flow chart each of the steps of an embodiment, whether upload to wagon, how to get out of it.
