Technical Field

The invention is related to a“nondiscriminatory access system for public/collective living spaces” which eases the access problems for the disabled without getting outside assistance, in public/collective living spaces, where the boarding platform is higher or lower than the ground level.

Prior Art

Climbing up and down from the lower level to the upper level where there is an elevation difference is extremely difficult especially for people who use wheelchairs or crutches, who have difficulty in walking and who are visually impaired. Even though solutions for passage from the lower level to the upper level, such as staircases are provided for people who are not disabled, these solutions are not applicable for the disabled and such staircases cause serious problems when used.

Today in the known state of the art, for the passage of non-disabled people from the lower level to the upper level;

• ramps

• elevators

• stairs or escalators

are used.

I n the present systems, since the system is generally used by getting help from others when a disabled person desires to climb a stair level, the time loss causes various difficulties for both the disabled and the person who assists the disabled.

I n addition, all other present systems are complicated and stationary systems whose mounting to the location is difficult and which have been produced with extra parts. At the same time, because of these are formed from extra parts, undesirable problems such as repair of extra parts can occur through time. The Purpose and Brief Description of the I nvention

I n developing the nondiscriminatory access system , it is aimed to achieve an access system which can be assembled and disassembled at the location with ease, which provides convenience for the end user, which has a simple structure that can be used at any point having an elevation difference, which is easy to use, which does not require frequent maintenance, which is durable against unforeseen loads and which has low cost of initial installation and during its operation.

The system developed according to the present invention is a system which can be assembled at any location with access problems and disassembled which provides convenience for the end user. With the fewest parts as possible to produce, the mobility of the mechanism has been improved. One of the most important innovations of the system is that the disabled person does not need to get assistance from others in any way when he/she climbs up the floor. Additionally, the system convenient for carrying the entire load within the capacity of this system is designed with such a width that a stretcher can be carried thereon. The system can also be used for carrying products or semi-products to the production line without interruption where there is an elevation difference in the production line in the industry. Along with all the other features it comprises, the system is one that can ease the disabled or non-disabled passenger and load transfer to all vehicles or to the port by being integrated to the port in maritime transport.

The most significant distinction of this system from the other solutions is that it is a universal design and it is a system that can carry more than one disabled person, not just one disabled person and the people assisting them . Briefly, this system is suitable for use in transferring the disabled, patients, doctors, other assisting personnel and additionally all other loads.

The basic principle of this invention is to develop a system which eases the access problems for the disabled individuals in all public areas, especially in the places where there is an elevation difference.

The most important elements (mandatory for the operation) of the nondiscriminatory disabled access system developed by this invention are as follows:

• A loadbearing body (main frame/main construction) ( 1 ) , of which a specific part is fixed to the upper level of the levels having a height difference and a specific part is fixed to the lower level,

• A horizontal platform (3) on which the disabled vehicle will be driven,

• Platform side brackets (2)which take place on both sides of the horizontal platform (3) and prevent the disabled vehicle from swaying to the left or right during the operation of the system ,

• Parallel rods (4) one end of which is mounted to the loadbearing body (main frame/main construction) ( 1 ) and the other end to the platform side brackets,

• Power and motion transfer component (5-A) , one end of which is connected to one of the parallel rods (4) and from its middle part to the second of the parallel rods (4) and the other end is connected to the power and motion transfer component element numbered 5-B,

• Power and motion transfer component (5-B) , one end of which is connected to the power and motion transfer component element numbered 5-A and the other end to the loadbearing body ( 1 ) (main frame/main construction) ,

• Power supply (6) ,

• Safety panel (13) which prevents the platform (3) from moving further than the required position of the platform as it moves from the lower position to the upper position,

• Safety panel motion component (14) which enables the movement of the safety panel,

• A fixed end connection ( 15) of a plunger to which the fixed end of the plunger is connected. The other elements which constitute the operation of the nondiscriminatory disabled access system developed with this invention and provide these with security features are as follows;

• The back screen (7) and the front screen (8) which prevent foreign objects from entering the bottom of the platform when the system is in operation and which prevents the mechanism from being seen,

• A protective panel ( 17) which prevent foreign objects from entering the bottom of the platform from the side of the platform when the system is in operation,

• The ramp / stopper (9) which enable the disabled to get on the platform together with his/her vehicle when the platform (3) is in the lower position and which prevents the disabled vehicle from moving backwards when the platform is moving,

• The ramp motion wheel ( 10) which prevents the ramp/stopper (9) from moving after the platform (3) moves from the lower position,

• The return spring (1 1 ) which enables the movement of the ramp motion wheel (10) ,

• Railings (12) that the disabled can hold on to and that prevent the disabled from falling.

The operation principle of the nondiscriminatory access system is as follows;

When the nondiscriminatory access system is at the lower position ;

The user passes onto the platform (3) with the help of the ramp/stopper (9) . The user activates the power supply (6) by pressing on the up button on the platform side bracket (2) . I n one embodiment of the invention, hydraulic/pneumatic plunger is used as the power supply (6) . As can be seen in Figure 1 ,2 or 3 he fixed end of the plunger is fixed to the connection point (15) and the moving part is fixed to the power and motion transfer component (5-B) . With the linear movement of the hydraulic/pneumatic plunger, the power and motion transfer components (5-A and 5-B) start to push the parallel rods (4) upward. Since one end of each of the parallel rods (4) are fixed to the platform side brackets (2) , the platform (3) departs from the ground. With the movement of the platform (3) , under the influence of the tractive force of the return spring (1 1 ) , the ramp/ stopper (9) goes to the stopper position. When the system arrives at the upper level needed to be reached, the safety panel motion component ( 14) moves the safety panel (13) and the distance control switches are activated and they stop the system . Thereby, the level the user desires to climb up to is reached.

If there is no new use demand related to the use of the disabled access system when the platform (3) is at the upper position, after staying at the (adjustable) upper position for a period, it can gradually go down to the lower position without any intervention.

When the disabled person is at the upper level and the system is at the lower level, when the disabled person desires to go down, he/she calls the system up by pressing the button on the loadbearing body (main frame/main construction) ( 1 ) .

When the nondiscriminatory access system is at the upper position;

When the user arrives at the platform (2) , he/ she activates the power supply (6) by pressing on the down button. With the linear movement of the hydraulic/pneumatic plunger, the power and motion transfer components (5-A and 5-B) parts start pulling the parallel rods (4) downward. Since one end of each of the parallel rods (4) are fixed to the platform side brackets (2) , they move the platform (3) downwards parallel to the ground level with the downward movement of the parallel rods (4) . At the same time, the safety panel motion component (14) moves the safety panel (13) downwards. When the disabled access system approaches the ground level, the ramp motion wheel ( 10) pulls the return spring ( 1 1 ) and enables the ramp/ stopper (9) to be brought to the exit position, which is the ramp position. At this stage, the safety panel passes on to the barrier position. Distance control switches are activated at the exit point and the system is automatically stopped.

I n order to keep from any inconvenience within the operation space of the disabled access system, the safe operation space of the system is defined with the help of boards on the side, the moving front screen (8) at the front and the safety panel at the arrival point.

I n Figure-5, the 2 ^nd application of the nondiscriminatory access system takes place. I n this application, a plunger is used as the power supply (6) . One end of the plunger is fixed to the loadbearing body (main frame/main construction) ( 1 ) and the other end to the switch levers ( 16) . One rod of the switch levers ( 16) is fixed to the junction point of the power and motion transfer components (5-A and 5-B) and the other rod is fixed to the ground. When the system passes on to the upper position from the lower position, the plunger pushes the switch levers ( 16) and enables the power and motion transfer components (5-A and 5-B) to move upwards. The upward movement of the power and motion transfer components (5-A and 5-B) provide the upward movement of the parallel rods (4) and the upward movement of the parallel rods (4) provides the upward movement of the platform (3) parallel to the ground.

I n Figure 8, the 3 ^rd application of the nondiscriminatory access system takes place. I n this application, a plunger is used as the power supply (6) . The fixed end of the plunger is fixed to the rod which is fixed to the ground from the switch levers ( 16) and the moving end of the plunger is fixed to the rod which is fixed to the power and motion transfer rod (5-A) from the switch levers ( 16) . When the system passes on to the upper position from the lower position, the plunger pushes the switch levers ( 16) and provides for the power and motion transfer component (5-A) to move upwards. The upward movement of the power and motion transfer component (5-A) provide the upward movement of the parallel rods (4) and the upward movement of the parallel rods (4) provides the upward movement of the platform (3) parallel to the ground.

I n Figure 1 1 , the 4 ^th application of the nondiscriminatory access system takes place. I n this application, a plunger is used as the power supply (6) . One of the switch levers (16) is fixed to the ground and the other end is fixed to the platform side brackets (2) . The fixed end of the plunger is fixed to the side brackets (2) and the other end is to the rod which is fixed to the plunger side brackets (2) from the switch levers ( 16) . When the system passes on to the upper position from the lower position, the plunger pushes the switch levers (16) and provides the upward movement of the platform (3) . The upward movement of the platform (3) enables the parallel rods (4) to move upwards and the upward movement of the parallel rods (4) enables the upward movement of the power and motion transfer rods.

I n Figure-15, the 5 ^th application of the nondiscriminatory access system takes place. I n this application, a plunger is used as the power supply (6) . One of the switch levers (16) is fixed to the ground and the other rod is fixed to the platform side brackets (2) . The fixed end of the plunger is fixed to the rod which is fixed to the ground from the switch levers and the moving end of the plunger is fixed to the rod which is fixed to the platform side brackets (2) from the switch levers. When the system passes on to the upper position from the lower position, the plunger pushes the plunger switch levers (16) and enables the upward movement of the platform (3) . The upward movement of the platform (3) enables the parallel rods (4) to move upward and the upward movement of the parallel rods (4) enables the upward movement of the power and motion transfer rods.

As the power supply, instead of the plunger, any one of linear systems, eccentric rods, cam systems, screw systems, hydraulic or pneumatic cylinders, gear wheel systems, chain or gear steel cords can be used. I n one embodiment of the invention, remote control is used instead of the buttons which provide the up and down movement of the system .
