In certain situations - ramps at thresholds divers from the main standards and solutions. These types of situations can for instance be: Special building constructions, old buildings and of course the general condition of the user of the ramp.
Example of a special solution:
- A narrow weather porch can be a problem for a person in a wheelchair - even with a threshold ramp installed.
A doorway build whitin a weather porch can cause problems - especially if the users condition is weak. It can be a problem - partly to turn the wheelchair due to the lack of space and partly it can be a problem to overcome rhe ramp since it is not possible to build up speed before reaching the ramp.
An elderly/week user vil be depending on a familymember or nursing personell in order to use the ramp.
- By raising the floor level the user of the ramps will get 2 small ramps instead of one big ramp.
It is possible to minimize these problems if the entire floor-level is raised in the whole weather porch. The first part of the ramp is now easier to climb and limited space is no longer an object.
This solution also means that the height of the threshold ramp at the front door is lower than before and therefore no longer a problem to overcome.
Example of level differenties between two rooms.
In old houses there is often level differenties between the rooms. If lack of space does not allow a relatively big ramp on one side - the only solution is therefore to remove the threshold completely. However the level differenties between the rooms will still exist.
Especially in these cases, it is very important that you choose the correct solution. Below you can se an example of a wrong construction. The threshold is removed and the ramp is build directly below the door. The problem is when the door closes it leaves a gap at the bottom allowing drafts to pass under the door.
- Example of a leven difference between two rooms. This situation is typical in older buildings.
- With a ramp mounted directly below the door there is the possibility of draft due to the gap between the door and the ramp.
The correct solution should instead be to extend the height from the top level allowing the door to close tight with the constructed repos. The ramp is mounted directly on the repos and will therefore be both lower and less demanding of space compared to keeping the original threshold.
- By extending the top level the gap between the ramp and the door is eliminated.
- When the door is closed there is no longer a gap and therefore no draft under the door.
