  • a motorized wheelchair for the transportation of a sitting person comprising a supporting frame provided with two side portions both having a plurality of threaded holes present on the inner side of said side portions, a couple of wheels both disposed on the outer side of said two side portions, a main body provided with the seat and provided with two side walls connectable between the two side portions of said supporting frame, and a plurality of threaded elements operable inside said threaded holes of said supporting frame and adapted to firmly constrain said main body to said supporting frame.
  • such a typology of motorized wheelchair also comprises means for self-equilibrating the weight thereof in any working condition, also employed in the device known with the name of SEGWAY® for the transportation of people.
  • Such means for self-equilibrating the wheelchair weight are housed inside said supporting frame together also with further means for varying the wheelchair forward movement direction.
  • the forward and/ or backward movement is obtained by means of the front and/ or back unbalancing of the user's body.
  • Further object of the present invention is to realize a method which allows to simplify the assembling operations of said motorized wheelchair.
  • the present motorized wheelchair for the transportation of at least one sitting person comprising a supporting frame provided with two side portions each having a plurality of threaded holes present on the inner side of both said side portions, a couple of wheels both disposed on the outer side of said two side portions, a main body provided with a seat and two side walls connectable to said supporting frame between said two side portions, and a device for constraining firmly said main body to said supporting frame, characterized in that said constraining device comprises at least one fixing plate hangable firmly on the inner side of least one of said two side portions of said supporting frame, at said plurality of threaded holes, and means for coupling translationally said main body to said fixing plate.
  • the assembling of the wheelchair main body with the supporting frame occurs simply and easily since the operations are carried out without having to provide complicated operations for aligning the main body to the frame and subsequent tightening the threaded elements from the inside of the main body.
  • the main body is translated, preferably from above, with respect to the supporting frame, by exploiting the presence of the fixing plate previously hanged to the supporting frame itself.
  • said coupling means for the translation comprise at least one couple of guide elements reciprocally translatable and, respectively, integral to said at least one plate and said main body.
  • a couple of guide elements preferably disposed vertically, is shaped such that the translationally coupling between said main body and said at least one fixing plate can occur from above downwards, or vice versa.
  • said at least one couple of guide elements comprises, respectively, at least one throat and at least one abutment profile being shaped in such a way to be translationally coupled inside said at least one throat.
  • said at least one throat and said at least one abutment profile have substantially a U-shape.
  • said at least one throat and said at least one abutment profile due to their shape, prevent any horizontal, front and back translation, of the main body with respect to the fixing plate and, thus to the supporting frame.
  • said fixing plate comprises, on the inner side, at least one projection such that said at least one throat is obtained in said at least one projection.
  • said at least one fixing plate, said at least one projection and said at least one throat are realized in a single piece, while said at least one abutment profile is realized in at least one of said two side walls of said main body by material removal of said at least one side wall.
  • said constraining device comprise as well means for blocking the translation of said at least one main body with respect to said at least one fixing plate.
  • said means for blocking the translation comprise at least one threaded element and at least one threaded hole to receive said at least one threaded element, said at least one threaded element and said at least one corresponding threaded hole being disposed, respectively, on the outer side of at least one of said two side walls and on the upper face, or one of the side faces, of said at least one fixing plate, or vice versa.
  • the blocking operation of the main body to the frame occurs from the outside of the main body such that the assembling of the main body and the supporting frame can be completed separately for, then, constraining them one to each other, without having to proceed to further assembling steps of other components.
  • a method for assembling a motorized wheelchair comprising the step of constraining said at least one main body to said supporting frame between said two side portions, characterized in that said step of constraining said at least one main body to said supporting frame comprises the steps of: fixing firmly, on the inner side of at least one of said two side portions of said supporting frame, said at least one fixing plate, at said plurality of threaded holes; and translationally coupling said main body to said fixing plate by said coupling means.
  • Such a method comprises subsequently the further step of blocking the translation of said main body and said at least one fixing plate by said means for blocking the translation. This advantageously occurs from the outside of the main body.
  • a motorized wheelchair for the transportation of a seating person has been denoted with numeral 1.
  • Such a wheelchair 1 comprises a supporting frame 2 provided with two side portions 3, 4 (herein not clearly visible) each having a plurality of threaded holes 5 present on the inner side 3a, 4a of each one of said side portions.
  • the side portion 3 can be seen, however the side portion 4, being opposite to the other mentioned side portion 3, is the same as the side portion 3 and symmetrical with respect to a longitudinal axis of the wheelchair 1.
  • the supporting frame 2 takes a U-shape.
  • the wheelchair 1 comprises a couple of wheels 6, 7 each one disposed on the outer side 3b, 4b (not visible in figures) of said two side portions 3 and 4, a main body 8, provided with a seat 9 and two side walls 10 and 11 connectable to said supporting frame 2 between said two side portions 3 and 4.
  • said wheelchair 1 comprises, as well, a device 12 (see figure 7 ) for firmly constraining said main body 8 to said supporting frame 2.
  • motorized wheelchair 1 also comprises means (herein not shown) for self-equilibrating the weight thereof in any operating condition, which are also employed in the device for the transportation of people known with the name of SEGWAY®.
  • Such means for self-equilibrating the wheelchair weight are housed inside said supporting frame 2 together with further means too for varying the wheelchair forward movement direction.
  • the forward and/ or backward movement is obtained by means of the front and/ or back unbalancing of the user's body.
  • said constraining device 12 comprises two fixing plates 13 (in figures only one fixing plate is visible) firmly hanged, respectively, on the inner side 3a and 4a (this latter not visible in the figures) of said side portions 3 and 4 of said supporting frame 2, at said plurality of threaded holes 5, and means 14 for translationally coupling said main body 8 with said fixing plates 13.
  • said translationally coupling means 14 comprise four couples of guide elements 15, 15, wherein each couple comprises two guide elements 15 and 16 reciprocally translatable and, respectively, integral to said plate 13 and said main body 8.
  • each fixing plate 13 comprises, on its own inner side 13a, two projections 20, in such a way that the two throats 15 of the two couples of above mentioned guide elements are obtained in said projections 20.
  • each fixing plate 13 comprises, on its own inner side 13a, two projections 20, in such a way that the two throats 15 of the two couples of above mentioned guide elements are obtained in said projections 20.
  • the fixing plate 13, the two projections 20 and the two respective throats 15 are realized in a single piece.
  • the abutment profiles 16 are realized, two by two, in the two side walls 10 and 11 (visible in figures 6 and 7 ) of said main body 8 by material removal of said side walls 10 and 11.
  • such abutment profiles 16 are obtained inside the side wall 10 and 11 in such a way that when the single throat 15 is coupled with the respective abutment profile 16, the outer edge 40 of the throat 15 is coupled by interference with the outer edge 41 of the single abutment profile 16.
  • an outer edge 41 is obtained by material removal of the side wall 10 in such a way that a perimeter hollow 42 is present running inside and parallel along the perimeter of the same edge 41 inside which the outer edge 40 of the throat 15 inserts.
  • said constraining device 12 comprises, as well, means 29 for blocking the translation of said main body 8 with respect to said two fixing plates 13.
  • means 29 for blocking the translation 29 comprise two threaded elements 30, each one disposed on the two outer sides 10a (herein not shown) and 10b of the two walls 10 and 11 of said main body 8, and two corresponding threaded holes 31 for receiving their own threaded element 31.
  • Each one of said threaded holes 31 is disposed in the upper face 13b of each fixing plate 13.
  • the two threaded elements 31 are disposed outside the main body 8 such that once the translationally coupling between the main body 8 and the supporting frame 2 has occurred, the blocking between main body 8 and supporting frame 2 occurs from the outside of the main body 8 simply screwing the threaded element 30 on the threaded hole 31.
  • the embodiment illustrated in the attached figures shows, for each side of the main body 8, and therefore, of the supporting frame 2, a vertical threaded element 30 and a corresponding threaded hole 31 with vertical axis for blocking the vertical translation of the main body 8 with respect to the fixing plate 13. This is due to the fact that the translationally coupling means 14 are disposed vertically for the vertical translationally coupling between main body 8 and fixing plate 13.
  • a method for assembling a motorized wheelchair 1 comprising the above discussed characteristics, and in particular a wheelchair 1 according to one or more of the claims from 1 to 9.
  • Such a method comprises the step of constraining said main body 8 to said supporting frame 2 between said two side portions 3 and 4.
  • said step of constraining said main body 8 to said supporting frame 2 comprises the steps of: fixing firmly, on the inner side 3a and 4a of said two side portions 3 and 4 of said supporting frame 2, said two fixing plates 13, at said plurality of threaded holes 5; and translationally coupling said main body 8 to said two fixing plates 13 by said guide means 14.
  • the further step of blocking the translation between said main body 8 and said two fixing plates 13 by said means for blocking the translation is comprised.
  • any possible translation between said main body 8 and said fixing plates 13 can be blocked and, thus, between said main body 8 and said supporting frame 2.
  • the connection between the main body 8 and the supporting frame 2 is made highly firm, but also assembling the wheelchair 1 is highly simple.
  • alignment steps between main body 8 and side portions 3 and 4 of said supporting frame 2 do not need neither to be provided, nor main body 8 and supporting frame 2 have to be blocked by complicated operations for tightening screws disposed, partly, inside the main body 8 to cross it and thus to screw onto the plurality of holes present on the inner side of the two side portions.
  • the solution allows to perform the assembling operation from the outside of the main body 8, once the latter is translationally coupled to the two fixing plates 13.
