Definitions

  • the invention relates to a foldable wheelchair with two side frames, in each of which a front wheel and a rear wheel is mounted, as well as with a arranged between the side frame scissor element having two scissor arms, wherein the scissor arms are pivotally mounted in the side frame in the region of a Scherenimplantationndes.
  • Such folding wheelchairs are well known from the prior art, for example from the FR2574287 . EP1913917 and the DE 20 2008 009 608 U1 .
  • a scissor element also called cross strut, use.
  • the pivot axis of the scissor arms of the scissor element is in this case arranged parallel to the footprint of the wheels of the wheelchair on a floor.
  • the common pivot axis of the two scissor arms of the scissor element is arranged horizontally.
  • this pivot axis moves upward, thus in a vertical plane.
  • the lower ends of the scissor arms are rotatably mounted on lower horizontal frame tubes of the side frames.
  • a seat tube is welded horizontally.
  • These horizontally welded seat tubes rest in the unfolded state of the wheelchair on the seat tubes matched bearings that are attached to upper horizontal tube sections of the seat frame.
  • the horizontally welded seat tubes move freely upward while the side frames move towards each other.
  • a tab which is rotatably connected both with a scissor element half as well as with the corresponding side frame, ensures that the side frames are guided in parallel during the folding process and the seat tubes of the scissor element are positioned exactly in the camps.
  • Object of the present invention is to develop a foldable wheelchair of the type mentioned so that, with high stiffness of the wheelchair in unfolded state, the wheelchair with respect to its width can be folded to a compact Faltiety.
  • the handling The wheelchair for unfolding and folding should be very easy.
  • the scissor arms are pivotally mounted in the region of the other Scherenimplantationndes in manually operable actuators, which are mounted at a distance from the pivot axis of the other Scherenimplantationndes in the actuators, pivotally mounted in the side frame, and at a distance from the other Scherenelementende a Faltscharnier is arranged, which is pivotally mounted in the side arms, further comprising an adjusting means, which is pivotally connected to the folding hinge, at a distance from its bearings in the side frame, and between the folding hinge and one of the actuators, at a distance from the pivot axis of this actuator in the associated therefrom, is effective, further comprising means for fixing at least one actuator relative to the said actuator associated side frame in the unfolded position of the wheelchair.
  • the particularly high rigidity of the wheelchair in unfolded state due to the formation of the wheelchair is effected both with the scissor element and with the folding hinge.
  • the fixed ends of the scissor element are associated with the side frame and it is associated with the loose ends of the scissor element the manually operable actuators which are pivotally mounted in the side frame.
  • the change in the pivotal positions of the manually operable actuators results in pivoting the actuators in one direction to a greater spread of the scissor arms of the scissor element and thus to a unfolding of the wheelchair, while pivoting the actuators in the opposite direction to a stronger closing of the scissor element, with the consequence of folding the wheelchair leads.
  • the adjusting means which is pivotally connected to the folding hinge, at a distance to its bearings in the side frame, serves to couple the movement of the folding hinge and the one manually operable actuator.
  • This coupling can be designed differently and also be effective differently, for example linear or non-linear.
  • the adjusting means directly transfer the movement of the actuator to the folding hinge, both in the direction of movement of the folding hinge for transferring the wheelchair in the unfolded position and in the other direction of movement for transferring the wheelchair in its folded position.
  • the adjusting means may well be associated with the cooperating with the actuator loose end of the scissor element.
  • the adjusting means may be formed as a rigid or even as a variable-length component; latter design in particular, in cooperation with spring means, which are effective between a side frame and the folding hinge or a side frame and the actuating means.
  • a bearing rod is mounted for a push handle for pushing the wheelchair.
  • This bearing rod forms in particular a back tube for receiving a back cover, thus a tube in the area of the back of the person using the wheelchair. Since it is necessary for the transfer of the wheelchair from the unfolded state in the folded state, to operate the actuators manually, this can be done according to the aforementioned development in a simple manner that by pivoting the bearing rod in consequence of introducing forces in the push handle , this folding process is completed. In addition to this possibility to transfer the wheelchair due to this simple movement from the unfolded state in the folded state, and vice versa, this makes it possible to convert the wheelchair when folding in a particularly space-saving arrangement.
  • the bearing rods or the back tubes can be pivoted with the push handles in particular on the side frames, preferably to almost to rest the bearing rods on the side frame.
  • the extent of the wheelchair is thus reduced not only in the width direction, but also in the height direction to a minimum.
  • the respective storage bar with unfolded position of the wheelchair, perpendicular to the ground plane of front wheels and rear wheels on a floor on which the wheelchair is placed, and it is in the folded position of the wheelchair, the bearing rod in the region of the push handle receiving end adjacent arranged the associated page frame.
  • the respective actuator for transferring the wheelchair from its unfolded position to its folded position, by an angle of 80 to 90 °, in particular 90 °, is pivotable. In such a pivot angle is particularly ensured that a cooperating with the respective actuator bearing rod or a back tube in the frame facing the end position, in folded wheelchair, can be transferred.
  • the folding hinge is foldable in a plane which is parallel to the contact surface of front wheels and rear wheels on a floor. If the floor is horizontal, this means that the folding hinge is foldable in a horizontal plane.
  • This arrangement of the folding hinge is particularly advantageous in terms of space and a particularly simple connection of the folding hinge to the actuator.
  • the folding hinge in the folded state is directed to the rear axle of the wheelchair formed by the rear wheels.
  • this is thus directed to the scissor element.
  • This folding direction is also seen under the aspect of a compact arrangement of folding hinge and scissor element in the wheelchair.
  • the one scissors element ends and the folding hinge are connected to the side frame in front of the rear axle formed by the rear wheels, and the other scissors element ends are mounted behind the rear axle in the actuators.

  • This design results in a particularly simple connection of the scissor element with respect to the two side frames and the two actuators.
  • the adjusting means in the region of its end facing away from the folding hinge, is pivotally mounted in one of the actuators or pivotally mounted in an actuator mounted in the receptacle for one of the scissor arms.
  • This end of the actuating means thus undergoes a movement corresponding to the actuator or the receptacle for the one scissor arm during pivoting of the actuator.
  • the adjusting element is telescopic and a stop for limiting the collapsing movement of the actuating element when unfolding the wheelchair having.
  • the length of the telescopic actuator decreases until the stop is effective and thus the actuator as a rigid element
  • the movement of the actuator on the one hinge arm of the folding hinge geometrically positively coupled transmits, in particular so far, to unfolded wheelchair, the folding hinge assumes its extended position.
  • means, in particular spring means are provided which are effective between one of the side frames and one of the hinge parts of the folding hinge.
  • the actuators are pivotally mounted in the region of the rear ends of the side frames and arranged bearing shafts of the scissor element in the region of the other Scherenimplantationndes below and behind bearing axes of the actuators in the side frame. This ensures that on the one hand the other scissors element ends can be stored stable and low-backlash and on the other hand, the bearing rods or back tubes defined position on the rear ends of the side frame and can support.
