Description

TECHNICAL FIELD OF THE INVENTION

This invention is related to an access system for disabled persons who are blind or using wheelchairs or crutches, in order to help them to navigate between elevation differences. System has a moving platform to get up to the higher level or descend down the lower level.

STATE OF ART

It is so difficult to navigate between the elevation differences especially for the people who have mobility impairments such as wheelchair or crutches users or for the blind people. Solutions like stairs are developed for navigation between lower level floor to the higher level floor (elevation differences), but these solutions can not be used by the people who have mobility impairments and they cause serious problems when they are used by those people.
Today,

ramps,
elevators,
stable or moveable stairs

Slope of the ramps should not exceed 4-5 % in any direction in order to let people use their wheelchairs by themselves securely and functionally. On the other side, this slope should not exceed 8% for the wheelchairs driven by companions (persons other than wheelchair users). These low percentages for the ramp slopes cause horizontally long and space taking ramps especially in the case of relatively higher elevation differences. It is needed to get help from other persons to drive wheelchairs in case of the higher percentages in slopes. In these situations, there occurs the risk of having wheelchair quite out of hand which means risk and danger. The calculation of the width of the ramps according to its location is also important. For instance, width of the ramps -which would be build sidewalk should be at least 120 cm. For the ramps which are not located at the edge of the sidewalk should be minimum 180 cm in order to let two wheelchairs access side by side. Additionally, it is important to take manoeuvrability area of the wheelchair into consideration. Surface qualities of the ramps are also important for the secure navigation of the disabled people that they should be firm (hard), stable, slip resistant and a little bit rough. All of these details mean high labor and production costs and time consuming.
Those solutions beside the ramps such as the short-level elevators, lifts and moveable stairs have high costs. They are open to risks especially when they stuck in between the elevations (levels); sometimes, it is impossible for the users to control them at these problematic situations.
EP 1 160 391 A2 , US 5 947 231 A and GB 2 170 174 A show access systems for disabled persons using ramps.

DETAILED DESCRIPTION OF INVENTION

Access system for disabled which is developed by the present invention mainly comprises;

Lower level platform (1)
Sloped platform (2)
Hinged connection between sloped platform (2) and higher level (6) and
Lifting and lowering means (4).

Lower level platform (1) placed on the lower level (5). Sloped platform (2) is in between the lower level platform (1) and higher level (6). Sloped platform (2) and higher level (6) are connected by hinge (3). Hinged connection (3) between the sloped platform (2) and higher level (6) makes sloped platforms (2) upwards and downwards movement possible.
When sloped platform (2) is lifted by lifting and lowering means (4), sloped platform (2) aligns/(come into line) with the higher level (6) by the help of hinged connection (3) and gets the horizontal position.
Access/navigation of a disabled person from the lower level (5) to the higher level (6) is shown in the Figures 2, 4, 5, 18, 30 and 32. If lower level platform (1) is in the touching position to the lower level, user gets up the lower level platform (1) and starts the system. If lower level platform (1) is not in the position of touching the lower level, disabled person has that required position by using control units (10). He/she gets up on the lower level platform (1) and starts up the system. Sloped platform (2) is lifted by lifting and lowering means (4), sloped platform (2) aligns/(come into line) with the higher level (6) by the help of hinged connection (3) and gets the horizontal position. By this operation, disabled person can access to the higher level (6).
Usually, connection between the sloped platform (2) and the lower level platform (1) is fixed. For special applications as can be seen in the Figures 24, 25 and 26, this connection can be different type of hinges.
Access/navigation of a disabled person from the higher level (6) to the lower level (5) is shown in the Figures 3, 19, 31 and 33. If sloped platform (2) is inline with the higher level (6) and horizontal, he/she gets on the sloped platform (2). If sloped platform (2) is not inline with the higher level (6), he/she has it in required position by using control units (10). And then, he/she gets on the sloped platform (2) which is horizontal position and starts the system. Sloped platform (2) is lowered by lifting and lowering mechanisms (4) and gets the sloped position. So, disabled person can access slowly to the lower level platform (1) and then to the lower level (5).
Lower level platform (1) of the access system for the disabled which is developed in this invention is designed to keep its horizontal position continuously during the lifting and lowering operations as shown in the Figures 24, 25, 26 and 34. For this application, there is a Fitting of the hinged connection (43) between lower level platform (1) and slopped platform (2). So, lower level platform (1) keeps its horizontal position in all heights/levels during the lifting and lowering operations.
As shown in the Figure 24, lower level platform (1) always keeps its horizontal position ,parallel to the lower and higher levels (5 and 6), by the help of parallel balance bars (37). During the lifting and lowering operations, lower level platform (1) keeps its horizontal position according to the sloped platform (2) by the help of hinged connection (43) between them, where as sloped platform's (2) position can be changed from sloped position to the horizontal position or vice versa.
The shaft adjusting the angle according to the height (38) can be used to keep the lower level platform's horizontal position (parallel to the lower and higher levels (5 and 6)) in all heights/levels. One of the ends of the shaft (38) is connected to the fixed pivoted connection point of the shaft (39) on the side wall, the other end is connected to the lower platform's end connection (40). Lower platform's end connection of shaft (40) is connected to the lower level platform's end. Details of this application are shown in the Figures 25 and 34. During the lifting and lowering operations, lower level platform (1) keeps its horizontal position according to the sloped platform by the help of hinged connection (43) between them, where as sloped platform's (2) position can be changed from sloped position to the horizontal position or vice versa.
A parallel scissor lift (which works at equal angles) which will be placed under the lower level platform can be used to keep the lower level platform's (1) horizontal position (in other words parallel to the lower and higher levels (5 and 6)) in all heights/levels. Scissor lift (41) is connected to the guide on the lower level from one end, and the other side it is connected to the guide under the lower level platform (1). Since this Scissor lift (41) always works in equal angles, it keeps lower level platform (1) always in horizontal position.

This application which is suitable for vehicles can be run with 12V/24V; appropriate electrical installation and electric motor- reducer system are used.
Figure 18 represents the general view of another application suitable for vehicles.
With this vehicle application of the access system for disabled developed with this invention, platform can be designed as it can rotate after the disabled person get in the vehicle. So, disabled person can turn any direction he wants.
Because of this access system for disabled persons developed with this invention is a moving system, there is a possibility of children (or pets) getting under the platforms (1 and 2) while the system reaches the highest position, and there can occur risky situations when the system restarts. In order to avoid this risky situations, a partition or a collapsible plate (11) is mounted at the end side of the sloped platform. Additionally, a safety partition (36) can be mounted under the lower level platform (1). This safety partition (36) can be like flat curtain or can be accordion type. These partitions (11 and 36) both hide the lifting and lowering mechanisms (4) and prevent the risky situations. Figure 19 shows the movement of the access system together with the safety unit (36).
In order to avoid the entrance under the lower level platform (1) while it is inline with the highest level, there can be constructed a kind of stable wall or a kind of set made up of metal or another material. In such an application, the partition under the lower level platform (11 and 36) can be mounted only the back side of the lower level platform (1).
When the disabled person is on the higher level (6) and the sloped platform (2) is in the sloped position, in order to avoid disabled person to go through the direction of the sloped platform; and additionally, when the sloped platform is in the horizontal position, in order to help disabled person to access to the platform easily, higher level platform stopper (safety stopper) (13) can be mounted on the sloped platform's (2) end side which touches the higher level (Figure 20 and 21). Sloped platform higher level stopper (safety stopper) (13) can be hinged or equipped with central spring. It aims to help user to access from higher level to the platform, and provides safety usage to the user.
In order to help disabled person to access lower level platform (1) and in order to avoid sliding backwards when the system starts, to the bottom end of the lower level platform (1), a slope for get in and stopper against sliding backward (12) can be mounted (Figure 22 and 23). Lower level platform slope for get in and used as stopper against sliding backward (12) can be hinged or equipped with central spring. It aims to help user to access to the platform, and provides safety usage to the user.

In order to adjust the height during the assembly of the access system for disabled developed with this invention, there are height adjustment legs (9). Height adjustment legs (9) can be screw drive, conical or pivoted. Its aim is to adjust the height of the system to the place it is going to be assembled in the best way as it is going to run in the best state.
The partition or collapsible plate (11) under the sloped platform (2) and the safety partition (36) under the lower level platform (1) can be curtain like partition or can have bellows or telescopic surface. The aim of the partition or collapsible plate (11) and lower level safety partition (36) is to cover and hide the lifting and lowering mechanisms (4) and to avoid unwanted situations like children (or pets) getting under the platforms while the system reaches the highest position. Besides, it helps the aesthetical unity of the system.
Directing guides or some specific textures such as indents or raises with guiding feature like bearings, reliefs can be applied on the surfaces of the lower level platform (1) and sloped platform (2) in order to get easier wheelchair movement. Aim is to provide safety to the user and guiding his/her direction.
Control systems (10) of the lifting and lowering mechanisms (4) of the access system for disabled developed with this invention can be one of the following: electrical, electronical, wired, RF or with bluetooth and so on. Movement sensors connected to the control system can be mounted under the lower level platform (1) and sloped platform (2) in order to increase the safety. So, system can be blocked/stopped in the case of unwanted entrance of cats, dogs or children under the platform. Additionally, system blocker/stopper sensors or similar setups can be mounted for the cases of overload.
