Definitions

  • a person having to use a wheelchair is rarely adapted to the height of the places to be used, kitchen, library, cash dispenser, shop displays ... and therefore cannot perform the tasks that they wish to carry out. well.
  • Some motorized wheelchairs that is to say having a motor allowing the movement of the wheelchair have options allowing to modify the height of the seat using a mechanism actuated by the motor of the wheelchair. These wheelchairs are heavy and mainly intended for people who can no longer move on their own.
  • the purpose of the present invention is to allow people requiring the use of a manual wheelchair, that is to say who does not have a motor allowing the movement of the wheelchair, to be able to adapt the height of the seat of their wheelchair. according to their activity.
  • a manual wheelchair must be as light as possible so as not to reduce the freedom of movement of people.
  • the manual wheelchair defined in claim 1 achieves these goals.
  • a manual wheelchair according to the invention allows a vertical movement of the seat of the manual wheelchair and is characterized in that it comprises a frame having two symmetrical sides each supporting a double scissors on which is fixed the seat of the wheelchair, a mechanism to activate the movement of the scissors and a control device verifying that the wheelchair is braked and that its inclination allows the seat to be raised without risk for the user.
  • the structure of the double scissors keeps the weight of the wheelchair within an acceptable limit, the double scissors coming to fix it on the chassis at the front and on the movement mechanism implies that almost the whole structure of the chassis is in traction which allows to have a light structure.
  • the seat 5 and the footrest 6 are fixed to the top of the two double scissors 7.
  • the height of the seat 5 depends on the position of the nut 10, when the nut 10 is behind the seat 5 is in the low position, if the nut 10 is moved towards the front of the chair, the angle formed with the horizontal and the sections 13, 14, 15, 16 increases which has the consequence of pushing the seat 5 against the top.
  • the handles 2 for pushing the wheelchair are fixed to the support of the rear wheel axle 3.
  • the weight of the chair is as light as possible, when a person is seated the center of gravity is quite high.
  • an electronic control system checks that the inclination of the wheelchair allows seat 5 to be mounted while remaining stable.
  • the electronic control system checks that the wheelchair is braked before authorizing the seat 5 to rise in order to prevent the wheelchair from moving while the seat 5 is in the high position.
  • This control system also controls the mechanisms 11 of scissor movements 7 in order to synchronize the two sides of the seat.
  • the mechanism 11 will consist of a system making it possible to have air or liquid pressure in place of the electric motors 8 and of pneumatic or hydraulic jacks in place of the movement screws 9. These cylinders may be arranged for example at the location of the movement screws 9 or between the bottom of the profile 14 and the second upper half of the profile 13.
