Definitions

  • the present invention relates to an assembly, in particular in the form of a kit, for a manually driven wheelchair for the physically disabled, facilitating the lateral transfer of the user to and from the chair.
  • Manual drive wheelchairs have large diameter rear wheels, to allow manual drive by the circular handrails presented by the wheels. These wheels form an obstacle to the lateral transfer of the disabled person between the chair seat and another adjacent seat.
  • EP 1192924 describes a wheelchair requiring the presence of rear casters and means of lifting the chair to allow the large rear wheels to slide.
  • GB 2141980 describes a wheelchair with a complex sliding frame.
  • US 2016175174 a wheelchair allowing lateral transfer of the user.
  • JP2009 178492 describes wheelchairs in which the actuation and unlocking of the wheels between these two positions is carried out by complicated drive mechanisms.
  • JP2009 178492 describes a telescopic sliding device that is less bulky in the longitudinal direction, but complex and requiring actuation by levers.
  • FR 15/01566 And EP 3120818 describe a set solving these problems, which can be presented in the form of a kit easily mounted on the most existing manually driven wheelchairs, the length of the elongated slide being such that it can, in the rear or rearward position, come out overhanging the rear end of the guide which does not exceed, or only slightly, the rear end of the chair, the slide remaining held in the guide by its front part.
  • FR 16/01635 , FR17/00045 And EP 3323400 describe such assemblies in which releasing the rear wheels to allow the user to move the rear wheels, then fixing them in the forward and rearward positions, are particularly practical.
  • the present invention proposes to remedy these drawbacks and to provide such an assembly of great lightness, even easier to mount on most existing wheelchairs, of great simplicity, and allowing the spacing of the wheels to be maintained. rear, this assembly also being of simple construction and easy assembly.
  • horizontal position we mean a horizontal position or a slightly inclined position, preferably towards the rear, at an angle of 0 to 5°.
  • the automatic release means making it possible to return the detent means to the detent position during the movement of the wheel slider may comprise, for example, a spring returning the lever to the detented position.
  • these means simply reside in a position of the articulation of the lever allowing it to return to the engaged position, by simple gravity after the movement of the slide has moved it away from the holding means.
  • the lever is articulated on the slide, and then carries said spaced latching elements, the guide then carrying the complementary latching element.
  • the articulation is preferably located towards one of the ends of the lever, more preferably towards the front end.
  • the articulated lever has reliefs, holes or latching notches separated along the lever, of a distance corresponding to the stroke of the slide between the advanced and rearward wheel positions, and intended to snap into a notch, a hole or a complementary relief presented, preferably, by the guide.
  • the lever thus has two notches in its lower edge, so that once lifted then moved slightly by the movement of the slide, the lower edge of the lever slides on the fixed relief until the other notch reaches above the fixed relief and engages there, preferably by simple gravity.
  • the means for maintaining the non-latched position are magnetic means, preferably consisting of a simple magnet, preferably in the shape of a small vertical disk.
  • these means comprise a simple fixed magnet, presented, preferably, by the guide, above the trajectory of the lever, the upper edge of which has at the level of each hole or notch a ferromagnetic part which can be applied against the magnet when the lever is raised, the ferromagnetic part located at the level of the notch corresponding to the normal advanced position of the wheel being further from the longitudinal geometric axis of the lever than the other, in order to compensate for its lesser amplitude of movement during rotation of the lever, in the preferred case where the articulation axis of the lever is located outside the distance separating the latching elements of the lever.
  • it is the lever which can carry two magnets cooperating with a fixed ferromagnetic part.
  • these means comprise two magnets carried, preferably, by the slide which can cooperate with two ferromagnetic parts, then carried by the lever.
  • the means for maintaining the released position thus ensure the automatic release of the lever, which escapes the magnet when the slide moves from its advanced or retracted position, the lever then automatically returning to the latching position.
  • the device preferably has a stop means preventing its slide from advancing, in the guide, beyond its normal advanced rolling position, as well as a stop means preventing it from moving back beyond its rearward position and escape from the guide.
  • This last means can be simply formed by a rim of the relief, hole or notch of the lever's front latching, coming against a fixed relief, hole or notch and preventing the lever from moving back further, even in the non-raised position. snapped into place.
  • a notch in the guide open towards the rear, so as to receive the axle or rear wheel bearing in its forward position.
  • the bottom of this notch forms the stop means preventing the slide from being extracted forwards.
  • the guide comprises a thin planar vertical element having means of fixing on one side to a part of the chair frame, and, on the other side, rolling members holding and guiding the slider, said slider comprising a flat and elongated vertical element, of small thickness, held and guided, preferably on and under its long edges, by said means of bearing, the detent lever having the shape of a flat elongated blade, extending parallel to the slide, operable by a lever or handle located towards the front and/or rear end.
  • the lever is carried by the slide and is articulated on one of the faces of the slide, preferably towards the front of the slide.
  • This flat element can, preferably, carry, at a certain distance, a second flat element which is parallel to it, the slide, the rolling means and the lever being arranged in the space separating the two elements.
  • This second planar element can be connected to the first by solid connections, for example bolts, which makes it possible to prevent the slide from moving away from the chair in the event of abnormal stress tending to separate it from the rolling means.
  • this second flat element can be identical to the first, which simplifies manufacturing.
  • thin planar element of the guide is meant an element, for example a plate, with a thickness for example of 5 to 12 mm, more preferably 8 to 12 mm.
  • the length of the guide is 8 to 12 cm, the height of the guide being such that the guiding and rolling means that it carries can be located above and below the upper and lower edges of the slide.

  • the axis or fixed transverse sleeve presented by the slide, and on or in which the large rear wheel is mounted emerges from its device at a distance smaller than that of the axis or corresponding fixed bearing normally presented by the chair.
  • this smaller distance is substantially equal to said normal distance reduced by a value substantially equal to the thickness of the slide.
  • the invention thus makes it possible to obtain a total thickness of each of the two devices of the assembly, which may be less than or equal to 35 mm, in particular less than or equal to 30 mm, allowing the spacing of the two rear wheels, after assembly of the assembly, to remain substantially identical to that presented by the wheelchair before assembly of the assembly according to the invention.

  • This ferromagnetic part 74 is further away from the upper edge of the lever 64 by being carried or formed by a tab 75.
  • the operation is as follows.
  • the front stop 70 When the slide 15 arrives in its rearward position (see Figure 32 ), the front stop 70 is located under the notch 72, so that it engages by gravity in the notch, which immobilizes the slide 15 in its rearward position, the rear ferromagnetic part then being located at the level of the front magnet 69, from which it is distanced vertically.
  • the user raises the lever 64 again, so that the ferromagnetic part 74 comes into contact with the magnet, immobilizing the lever in the raised position and releasing the catch.
  • the user can then activate the big wheel and advance the slide 15, so that the lever 64, moving away from the magnet 69, falls back, its lower edge sliding on the stop 70, up to the advanced position in which the lever engages on the rear stop 70 ( Figure 30 ).
  • the front part 76 of the lever is thinner than the rest of the lever, so that the lever is in a very low position when the slide slides.
  • the device or kit may only include a single cylindrical brake part, and a single wheel sleeve, these parts being, preferably, already mounted on their respective supports. In this case we can even deliver the device, with the cover already mounted, and the two flanges with their tightening screws.
