Definitions

  • the object of the invention contained herein is a framework, used particularly for constructing the sides for wheelchairs for disabled people and wheelchairs with this system.
  • the invention has particular, but not necessarily exclusive, application in the sector of wheelchairs for disabled people.
  • wheelchairs There are various types of wheelchairs available for disabled people. They are basically made up of a seat part and a back part joined to a rigid frame, with a footrest attached to the front.
  • the frame which is static, is made up of a series of uprights and cross-members for the most part in tubular metal with a round section, that have the function of attaching two large-diameter wheels with hand-rails to the sides, and two smaller wheels that rotate and swivel on to the front part of the wheelchair.
  • attachments fastened to the back part, so that third parties may grip the said attachments in comfort to push and direct the wheelchair.
  • this type of wheelchair has a jointed cross-member that joins the two sides of the wheelchair which support the seat.
  • the jointed cross-member generally made out of tubular material, consists of joining and hinging two straight tubular elements in an intermediate position, with other straight, secondary elements orthogonal to the first elements, attached at the lower and upper ends.
  • the secondary tubular elements the ones at the lower end are used for attaching the sides of the wheelchair, while the other ends support the seat.
  • the seat is made out of padded cloth or other flexible material, so that it can be folded around the central part.
  • a particular specialist sector of the market is the "active" type of wheelchairs. These are different from the traditional type in that they have a lighter structure, are smaller and, above all, can be regulated in various points so that the user can find the ideal position according to the activity to be carried out.
  • This type of wheelchair that is also used for sporting activities, must guarantee above all increased stability, because of the speeds reached and the sudden changes of direction carried out with the wheelchair. This stability is given by the camber or, as in horse-riding, wheels similar to those used in car racing which allow the user to increase or reduce the amount that the wheelchair is leaned over according to requirements.
  • the wheelchairs in question are made up of two sides and a hinged cross-member for joining the seat and the back part, with each one made up of a pair of more or less horizontal, parallel tubular elements.
  • the upper one which comes out inclined from the front part, along with the symmetrical side, makes up a fixing point for the footrest.
  • the lower tubular element is attached to the upper one by means of straight, perpendicular elements. At least two of these elements are positioned close to the swivel points for the large wheels to form the quadrilateral for the system for the swivel and regulation points for the large wheels.
  • This latter area usually has a transversal plate that can be adjusted vertically in height, and can be joined to the ends along the perpendicular elements which have holes, to determine the height of the seat from the ground. This means that the centre of gravity of the wheelchair and the camber of the wheels may be varied.
  • the purpose of the upper horizontal element of each side is mainly to act as a fixing point for the seat and other parts, such as the arm rests and the brakes, while the lower element forms a vertical jointing means at the front for a corresponding swivelling wheel.
  • the use of a round section tubular framework means that removable fixing methods as an alternative to nuts and bolts are not practical, in that the use of a clamping system, for example, even if it is very tight, does not guarantee the stability required, and may even deform the tube.
  • tried and tested techniques are used to fix the seat to the sides, for example by using clips fixed rigidly to the structural elements that hold the padded seat or that stretch the cloth of the seat, and that are fastened to the sides by using screws or bolts.
  • the aim of the invention described herein is to overcome the aforementioned drawbacks.
  • the framework made up of elliptical tubes is more rigid and resistant. Consequently, the thickness of the framework may be reduced leading to a further weight reduction of the frame work.
  • a further aspect regards the quick assembly of the sides, an aspect that means that this type of wheelchair is particularly interesting from a production point of view, since it can be manufactured and assembled quickly at a lower cost than with the manufacture of traditional wheelchairs.
  • a wheelchair for disabled people (A), of the type known as “active”, is made up mainly of two equal and opposite elliptical or oval section tubular elements (1), one that forms the right hand side and one that forms the left hand side, along the rear part (11) of which the foldable seat (2) and back (21) are supported.
  • connection means that are fastened to a corresponding adjustment plate (3), to the lower part of which a large wheel (4) is fastened.
  • the said connection means are, in this case, two jaw-clamps, each one made up of two mobile elements, in this case non-symmetrical (12) and (13), external and internal respectively.
  • Each one of the said mobile elements is made up of a monolithic body preferably in plastic, with a part (121, 131) that has a similar shape on the inner side to the oval section tube (1).
  • each element (12), (13) has a hole (122, 132) through which a screw is inserted to connect it with the adjustment plate (3).
  • the said adjustment plate (3) is metallic and monolithic and has an angular shape, the top of which coincides with the fixing point of a respective large wheel (4).
  • a first bar (31) that forms the vertical adjustment rod for the side (1) and of the seat (2), and a second bar (32) at approximately 75° from the first one, so that the two lower ends converge in the same position (33).
  • This position (33) has a fixing hole, by means of at least one sleeve (5) for a large wheel (4).
  • Both of the peripheral bars (31) and (32) of each plate (3) are straight and are manufactured with a series of evenly pitched through holes in them (311) (312).
  • each side (1) there are two points for fixing each side (1) to the plate (3), and in particular the rear part (11), respectively a first one (312) for vertical adjustment (31) and a second one (342) corresponding to any of the positions (341) along the portion of arc (34) that acts on the inclination of the side (1).
  • the holed bar (32) its purpose is for fixing a wheel guard (6) that also doubles as an armrest, and other accessories such as, in this case, a brake (7).
  • the adjustment plate (3) is lightened by reducing the full areas of material. In this way, there will be two central reinforcement portions (8), with each one stretching along the internal perimeter from its respective lateral bar (31) (32) to the connecting portion of the arc (34).
