Definitions
- the invention relates to a wheelchair provided with an undercarriage comprising two parallel arms, which are provided with rotatable wheels near their ends, whereby said arms are pivotally interconnected by a cross beam.
- the invention furthermore relates to an undercarriage for such a wheelchair.
- a chair mounted on said undercarriage is a chair, on which a user can be seated.
- the chair of a known wheelchair is secured to the cross beam and, at some distance therefrom, to both arms.
- the arms pivot about the cross beam in order to absorb said bumps.
- the distance over which the arms can pivot is limited, however, since the chair is connected to the cross beam as well as to the arms. It is not possible to connect the chair to the cross beam only, since this will lead to undesirable pivoting of the chair and the cross beam with respect to the arms.
- the object of the invention is to provide a wheelchair which is capable of absorbing bumps more adequately.
- One embodiment of the wheelchair according to the invention is characterized in that said leaf spring is centrally pivoted to said part.
- FIGS 1 and 2 show an undercarriage 1 of a wheelchair, wherein the chair is not shown for the sake of clarity.
- the undercarriage 1 comprises to parallel arms, which are each provided with a wheel 3 near each end.
- the wheels 3 are rotatably journalled in bearings 4 with respect to the arms 2.
- the arms 2 are interconnected by means of a cross beam 5 extending transversely to the arms 2, whereby each arm 2 is pivoted to an end 6 of the cross beam 5 and is also capable of pivoting movement, in a direction indicated by arrow P1, about a pin 7 extending parallel to cross beam 5.
- a chair (not shown) is mounted on cross beam 5.
- a part, a battery container 8 in this case, is rigidly mounted on cross beam 5.
- a battery for energizing an electromotor (not shown), by means of which the wheels 3 are driven.
- the battery container extends from cross beam 5 to a position located beyond two wheels 3 positioned opposite each other.
- a stack of leaf springs 11 is centrally secured to one end 9 of the battery container 8 and between ends 10 of arms 2, which stack of leaf springs extends parallel to the cross beam 5.
- the stack of leaf springs 11 is connected to each arm 2 by means of leaf spring holders 12.
- the centre of the stack of leaf springs 11 is encased by a fastening element 13, which is connected to battery container 8 via a pivot 14. Said pivot 14 makes it possible for the stack of leaf springs 11 to pivot in a direction indicated by arrow P2.
- the arms 2 are also interconnected by a pull rod 15, which is pivoted to the arms 2 by means of ball joints 16.
- the pull rod 15 maintains a predetermined spacing between the arms 2. This may also be realized by means of the leaf spring holders 12.
- the operation of the undercarriage is as follows. When the wheelchair drives of a road which exhibits bumps, a wheel 3 of a first arm 2 moves in a direction indicated by arrow P3, and a wheel 3 of another arm 2 moves in a direction indicated by arrow P4, whereby said arms pivot about pin 7 in the direction indicated by arrow P1.
- the arms 2 thereby move independently of each other.
- the stack of leaf springs 11 will pivot about pivot 14 and/or deform mechanically, dependently of the movements of the wheels 3.
- the chair mounted on the cross beam will experience a movement which depends on the movements of the wheels and the mechanical deformation of the stack of leaf springs.
