Abstract
Description
- It is known that in the domain of the wheelchairs as aids for disabled people or who are temporarely disable named with the word "commode" the manufacturers research continuously to make improvements to purpose of obtaining more comfort for the users or at least to remove eventual possible discomforts.
- These wheelchairs have the particular detail that both the backrest and the footrests reciprocally recline in a connect way i.e. while the backrest reclines lowering, the footrests recline upraising.
- The tricks which are adopted are those to let that the above said inclinations can happen in accordance with the articulations of the body of the person who is using the wheelchairs in these stages of inclination.
- One of the most considered points is referred to the area matching with the articulations of the knee when it occurs the changement of direction of the lower part which upraises.
- Progressively to the raise of the lower limb it is necessary a progressive movement forwards of the related footrest following the stretching of the leg.
- At present in the market are existing devices which provide that but which are complicate and expensive.
- The said devices further to be complicate and expensive have the inconvenient that they don't raise the supporting elements of the footrest in order to obtain that the lower limb of the leg is aligned with the upper part of the leg, this last one placed over the seat padding.
- The purpose of the patent is that one to make a device simple and cheap which further to let move forwards progressively the hinging point of the element which supports the footrest in order to satisfy the stretching of the leg during the stage of raising of the lower part providing to let that this element of support of the footrest to be placed to the suitable level of alignment of the leg in order to allow the continuative support.
- The additional purpose of the patent it that one of make the above said device with the minimum of moving elements which could create problems of shearing and which would therefore to be protected by suitable protection crankcase.
- The said device is manufactured as below described.
- To the external edge of the tubular element sliding telescopically inside the side tube of the framing which support the seating, it is welded a fork with the opening upwards. The edge of the said fork is coupled with hinging in an area spaced out from the upper edge of the tubular element which supports the lower edge of the footrest.
- The upper edge of the tubular element which supports the footrest is connected by hinging to the edge of a plate which opposite edge is hinged to the structure of the framing of the wheelchair in an area beneath the seat.
- The programmed reciprocal distance of the three hinging axis parallel between them, the placing and the configuration of the fork welded to the telescopic element sliding inside the tubular side element of the seat and the configuration of the plate with the edges hinged , one to the upper edge of the tubular support element of the footrest and the other to the structure of the wheelchair in an area beneath to the seat frame, define the extent of outcoming of the telescopic element (and therefore the extent of advancing outwards of the footrest) and the level assumed by the support of the footrest referring to the seat.
- Those previously described is clarified by the examination of the enclosed drawings.
- The fig. 1 shows the wheelchair with the footrest in the lowered position equipped with the device made following the patent for the raising of the element which supports the footrest.
- The fig. 2 shows the detail enlarged of the raising device referring to fig. 1.
- The fig. 3 shows the wheelchair referring to the fig. 1 where the element which supports the footrest is raised to a level higher than the structure where the seat lays and with its defined advancing outwards.
- The fig. 4 shows enlarged the detail of the raising device referring to the fig. 3.
- From the examination of the figures it is possible to note that the wheelchair complete with the
bearing structure big wheels 2, of the smallfront wheels 3, of the seat 4 and of thebackrest 5, shows the supportingelements 9 of thefootplates 10, connected to the bearing structure not in a rigid way but by a particular device made following the patent which allow to them to be raised at a defined level and to be moved spacing out from the seat of a defined distance. - The device applied in reciprocity to the front part of each side of the seat include an element 8 telescoping in the
tubular element 7 which supports the seat 4 and to which free edge is welded afork 12 with opening upwards. - The said fork couples by the hinging 14 to the
support element 9 of thefootplate 10 in an area close to the upper free edge. - The device includes further at least a
plate 13 hinged 15 to an edge with the upper part of thesupport element 9 of thefootplate 10 and hinged 16 to the other edge with theelement 6 of the beneath structure of the wheelchair. - Raising the
footplate 10 and therefore the supporting element there is a combined action of the rotation of the above saidelement 9 around thepin 15, of theplate 13 which rotates around thepin 16 placing between them in reciprocal opening. - By this moving while the
hinging pin 15 loweres and spaces out from theseat 5 it is exerced a traction in reciprocity of the hinging 14 of thefork 12 which defines its moving and those of the telescopic element 8 welded to it, which slides outcoming. - Once reached the raising position defined for the
element 9 and the referredfootplate 10 it must be made the lockage acting on theknob 11 which avoids the sliding of theelement 9 inside thetubular element 7. - After everything above explained it results the validity of the invention referring to the device of the patent which in a simple and functional way allows to let in raising the
element 9 which supports thefootplate 10 and to place it at the suitable level in order to guarantee a laying with continuity of the raised leg having allowed the stretching during the raising stage. It doesn't go out from the patent for solutions that persons expert of that field could carry out also with improvements in case it uses the teachings of this patent.
