Definitions

  • the purpose of this invention is a wheelchair for disabled persons, of manual type, improved to change the height of the seat level, to adjust it according to the requirements of the disabled person who is using it.
  • the wheelchair for disabled persons opportunely improved, allows the disabled person to lower down, if necessary, the seating level to the height of installed sanitation (toilet, bidet, washbasin etc.), to lower it to the required height when approaching desks of working tables, so allowing the user to hold his back straight,. to lower it at the level of the normal chairs or seats in the transport means, and at the end, with the same lowering easiness, to restore the height of the seat when the wheelchair is used as wheelchair to be moved.
  • sanitation toilet, bidet, washbasin etc.
  • wheelchairs There are types of well-known wheelchairs: motor-driven wheelchairs, wheelchairs which can be equipped to climb steps for going up and down are known, wheelchairs with raisable seating to allow the disabled persons to reach for ex. to the different levels of shelves etc.
  • the level of the seat which is applied for the fixed manual wheelchairs is fixed and appears to be higher than the levels as previously mentioned of certain sanitation equipments.
  • the purpose of the invention is to eliminate the limits on the performances possible with the normal wheelchairs for disables presently existing in the market which are part of the known technique.
  • the execution is obtained structuring the wheelchair with the bearing framework which allows to support a separate framework connected to the seating (and connected to the backrest) which by hand control by the disabled who is over is lowered from the level adopted in the wheelchair when it is used as wheelchair; level which corresponds to that one owned by the normal wheelchairs marketed in line with the known technique.
  • the framework of the seating (and connected backrest) is connected to the below bearing framework in a way to stay somewhat apart from the said below bearing framework with connection mechanical elements of known type (with system of cross rods, with small connecting rods, ecc.).
  • the raise of the seating with the overlooking weight of who is seated is obtained by an actuator (which preferably uses the pressure of a gas in cooperation with a spring).
  • the disabled can contribute to raise or lower himself grasping the two handles placed on the front, one on the right and the other one on the left fixed to a bearing framework.
  • One of the objectives of this patent which achieves the wheelchair with the seating which can be lowered is that one of the simplification of the structure and of the various parts connected to the purpose to don't weight down excessively to don't create discomfort compared with the usual manual wheelchairs with fixed seating existing in the market.
  • the excessive weight would represent an important discomfort when the wheelchair must be manouvered and in particular raised to be for example placed inside vehicles.
  • Another objective of this patent is its praticalness of use which doesn't differ substantially from the normal manual wheelchairs with the fixed seating. Indeed to change the level of the seating the occupant must simply act on a lever applied in a comfortable position near one of the handles for anchorage of the disabled when he contributes to lower or raise the seating.
  • Another purpose of this patent which achieves the wheelchair with the seating which can be lowered is that one to conform the seating level to level of the seatings of the transport vehicles (cars, bus, ecc.) when the wheelchair is placed inside the vehicles allowing the disabled who occupy the seating to be in conditions to look out of the windows remaining straight, like the other passengers, without needing to recline the head.
  • the transport vehicles cars, bus, ecc.
  • the wheelchair object of the invention having the possibility to adjust the level of the seating, it can be mounted on the driving place of the vehicle, suitably adapted and homologated for disabled, replacing the normal seat with which it is usually equipped the vehicle, obviously having arranged on the floor the suitable locking and anchorage points.
  • the fig. 1 shows the manual wheelchair following the founded which seating is placed on the level which is adopted in the normal manual wheelchairs used which represent the status of the known technique.
  • the fig. 2 shows the manual wheelchair considered in the fig. 1 where know the seating results lowered in support to the below bearing framework which support it. They are not indicated the pushing wheels and the wheelchair on the back lays on the floor on two suitable castors with which it is equipped.
  • the front pivoting wheels result placed within the locking brackets which have front splits which allow the insertion of their axles.
  • the fig. 3 shows schematically the section of the bearing structure of the wheelchair following a vertical transversal median flat.
  • the fig. 4 shows schematically out of coupling the section of the frame of the seating following a vertical transversal median flat.
  • the fig. 5 shows schematically the section of the bearing structure of the wheelchair following a vertical longitudinal median flat.
  • the fig. 6 shows schematically out of coupling the section of the frame of the seating following a vertical longitudinal median flat.
  • the fig. 7 shows out of action the actuator for the movements of the seating until lowering also close to the bearing structure and to its reset ath the level owned by the wheelchair when it is used for its moving.
  • the fig. 8 shows axonometrically a side and a top view of the wheelchair of the patent with seating raised compared to the below bearing structure equipped with pushing wheels on its normal arrangement to be moved.
  • the fig. 9 shows axonometrically a side and rear view of the wheelchair of the patent with the seating raised, without the pushing wheels and with laying to the floor by auxiliary rear castors.
  • the front pivoting wheels are placed on the blocking stirrups fixed to the floor with frontal splits to insert the axles of the said front wheels and the pin with vertical location towards the floor, integral with the rear lower part of the bearing structure, (the active part of the pin is not visible on the figure) inserted in the locking apparatus fixed to the floor.
  • the fig. 10 shows axonometrically a side and top view of the wheelchair of the patent frontally locked to the floor with the front wheels and on the back with the vertical pin integral to the rear structure, as described in fig. 9.
  • the wheelchair includes a bearing framework 11 equipped with two pushing wheels 2 and two pivoting front wheels 3 supported by the joints 7 connected to the bearing framework 1.
  • the seating is equipped with a distinct framework 11 (supporting the backrest 12 and the armrests 14) which can be spaced out from the below bearing framework 1 from the upper arms 13 and 13' of levers making fulcrum in 19 and 19' in the bearing framework 1.
  • the arms 13 and 13' result connected by their ends to the seating framework 11 by the hinging 20 and 20' .
  • the lowering happens in a progressive and controlled way stopping where the occupant consider useful and this can be in continuity until leaning against the below framework 1.
  • the pivoting front wheels are stopped and kept in reciprocity to their axles on the suitable stirrups 22, and the rear pin 24 with vertical placement towards the floor, integral to the crossbar 10 fixed in the rear part of the bearing structure 1, is inserted and kept by the apparatus 25.
