Definitions

  • the present invention relates to a quick release device adapted to removably connect together a first and a second longitudinal tubes of a wheelchair.
  • the present invention relates also to a wheelchair that can be easily and quickly dissociated so as to permit it to be easily placed inside an automobile or other suitable conveyance.
  • a wheelchair is an important consideration to many wheelchair users.
  • One known solution to this problem consists in assembling different parts of the wheelchair with quick release assemblies that can be locked and unlocked without any tools, thereby allowing the user to easily make such a disassembling operation.
  • quick release assemblies do not securely connect together the different parts of the wheelchair. Indeed, a risk exists that the user inadvertently forgets to position the quick release assemblies in their locking position. In this case, two parts connected by such quick release assemblies may therefore be disconnected when the user is sitting in the wheelchair. If such a disconnection occurs when the wheelchair is running fast and if said parts correspond to frames which are supported on the ground by the rear wheels and the caster wheels respectively, such an event may lead to dramatic consequences for the user.
  • US 2009/194974 discloses a foldable wheelchair comprising a locking mechanism.
  • a first objective of the present invention is to provide a quick release device specifically designed so as to prevent an accidental disengagement of the parts of the wheelchair that are connected together by said quick release device.
  • a second objective of the present invention is to provide a quick release device that can be adapted to various wheelchair configurations without significant modification of the wheelchair.
  • a third objective of the present invention is to provide a wheelchair in which two frames supported on the ground by the rear wheels and the caster wheels respectively are removably and securely connected together.
  • the present invention provides a quick release device adapted to removably connect together a first and a second longitudinal tubes of a wheelchair, said quick release device comprising:
  • the quick release device permits to removably connect together the first longitudinal tube and the second longitudinal tube and prevents an accidental disengagement of said tubes when the user forgets to position the lever in its closed position. Indeed, if the lever is maintained in its locking position, the locking rod prevents an axial movement of the second longitudinal tube, fixedly connected to the second tubular element, relative to the first longitudinal tube, fixedly connected to the first tubular element.
  • situations and directions of elements of the wheelchair of the present invention are determined by the perspective of a user seated in the wheelchair. Accordingly, the rear side of the wheelchair corresponds to the top right side of Figure 1 .
  • the situations or directions “up” or “top” and “down” or “bottom”, “rear” or “back” and “front”, “behind” and “in front”, “upper” and “lower”, “lateral” and “central” follow the same rule.
  • a longitudinal direction corresponds to a back-to-front direction and a lateral direction corresponds to a left-to-right direction.
  • the terms “forward” or “forwardly” and “rearward” or “rearwardly” refer to the direction of motion of the wheelchair.
  • the horizontal corresponds to the plane tangential to the rear and front wheels and positioned under said wheels when the wheelchair is its normal position of use.
  • a horizontal plane corresponds to a plane parallel to the horizontal.
  • the vertical, or a vertical plane corresponds to a plane perpendicular to the horizontal.
  • FIG. 1 shows a wheelchair according to the present invention.
  • the wheelchair 100 comprises a quick release device 10 according to the present invention
  • the wheelchair 100 is almost identical to the wheelchair that was disclosed in the European patent application no. 11194954.7 filed by the Applicant, the content of which is integrated by reference into the present application.

  • the front wheels 121a, 121b are preferably casters and the rear wheels 111a, 111b are preferably drive wheels, which may be manually driven or power driven.
  • the main frame 110 includes a seat frame 112 and a backrest frame 114.
  • the seat frame 112 includes longitudinally extending frame profiles, such as left and right tubes 118a and 118b, for supporting a seat plate 116, which may preferably be in the form of a semi-rigid or rigid pan integral with said tubes 118a and 118b, as shown.
  • Said left and right tubes 122a and 122b of the front frame 120 are removably connected to said left and right tubes 118a and 118b of the seat frame 112 via left and right quick release devices 10.
  • each quick release device 10 comprises a first tubular element 12 slidably received inside and fixedly connected to one of the tubes 118a or 118b of the seat frame 112, preferably via screws (not shown) adapted to be received inside bores of the first tubular element 12 and the tube 118a or 118b respectively.
