Definitions

  • the invention relates to a foldable erecting wheelchair with a chassis, which has two side frames, which are held at a distance from one another by struts in the use state of the wheelchair.
  • Another disadvantage is the relatively large width of the folded chair, which also makes it impossible to accommodate in a small space.
  • Another The disadvantage is the relatively high rigidity of the chassis, which impairs the off-road wheelchair's ability to move off-road, because then all the wheels do not always rest on the ground in the event of uneven ground.
  • this is achieved in that at least one tension cable connects the two side frames to one another.
  • This configuration absorbs spreading and displacement forces and prestresses the struts.
  • the use of tension cables enables the number of struts and thus the weight of the wheelchair to be reduced. If, however, the number of struts is reduced, fewer struts have to be loosened when the wheelchair is folded up, or tensioned and secured when unfolding. This in turn makes it possible to dispense with connecting rods and connecting levers for the struts because the operation of a small number of struts presents no problems for the user of the wheelchair.
  • At least one tensioning cable runs practically parallel to the strut direction of two struts and at a distance from the plane in which the struts are arranged.
  • the fastening points of the struts and the tension cable on the side frame can be thought of as being arranged at the corners of a triangle.
  • the distances between the individual attachment points on the side frame can be dimensioned so that the desired stability and elasticity of the chassis is achieved.
  • At least one pair of tensioning ropes running diagonally to one another is advantageously provided. This increases the stability of the chassis.
  • the plane of the diagonals can run practically horizontally or practically vertically. Be It is particularly advantageous if two pairs of tensioning ropes running diagonally to one another are provided and the planes of the diagonals intersect approximately perpendicularly. The stability of the chassis is then increased.
  • the struts can have different constructions. They can also be designed as scissors. However, the design of the struts as lockable toggle levers has proven to be particularly advantageous. Toggle levers are relatively easy to operate with one hand, which is of particular importance if the wheelchair is to be set up and folded up by the wheelchair user himself, for example after or before driving a car.
  • the pair of tensioning ropes connects the two side frames at the top. This is particularly advantageous if a tension cable and a strut are arranged at the bottom of the chassis.
  • the pair of tension cables connects the rear part of the chassis in order to counteract the forces which exert the weight of the user on the seat and which endeavor to bring the two side frames together at the top front.
  • the erecting wheelchair shown in FIG. 1 has a chassis 11 with the front wheels 13 and the rear wheels 14.
  • the seat 17 and a height-adjustable support 19 are articulated at the front of the chassis at 15.
  • the seat 17 is biased upwards by a spring 16, so that the user of the chair only has to exert a relatively small force on the support 17 in order to move from the sitting position into the standing position.
  • a footrest 21 and a backrest 23 are articulated on the seat 17, the backrest 23 practically having the same angular position in every position of the seat 17 by means of a mechanism (not shown).
  • the erecting wheelchair is foldable. It is sufficient to inactivate three struts, of which only the strut 25 is visible in FIG. 1.
  • the struts are designed as toggle levers, so that it is sufficient to release the locking of the toggle levers and on the respective strut in the direction of FIG. 1 drawn arrows 27, 29 and 31.
  • the reference numbers 33, 35 and 37 show the respective plane in which the strut 25, 51 and 49 moves when folded.
  • the chassis 11 of the erecting wheelchair is shown in more detail in Figure 2.
  • the axes of the front wheels 13 in the position of Figure 1 are shown by dash-dotted lines 39 and 41.
  • the dash-dotted lines 42 and 43 indicate the axes of the rear wheels 14 of Figure 1.
  • the chassis 11 consists of two side frames 45, 47 which are connected to one another by two struts 49 and 51.
  • the strut 49 connects the lower parts of the side frames 45 and 49, while the strut 51 connects the rear parts of the side frames 45, 47.
  • a tensioning rope 53 runs practically parallel to the struts 49 and 51.
  • This tensioning rope advantageously consists of a stainless steel strand, means 55 being provided in order to change the length of the tensioning rope if necessary.
  • other materials can also be used for the tension rope, e.g. Nylon.
  • the means 55 can be formed, for example, by a screw 58 which has a sleeve 60 for receiving a rope end and is fastened to a side frame 45, 47 by means of adjusting means 62, 63.
  • two pairs 57, 59 of diagonally extending tensioning cables 57 ', 57 ";59',59” are also provided, the planes of the diagonals being arranged such that they intersect. While the pair 57 is practically horizontal, the pair 59 practically runs perpendicular. The pair 57 connects the two side frames at the top, while the pair 59 connects the two side frames at the rear.
  • FIGS. 3a-d show the structure and the mode of operation of a strut using the example of the strut 49.
  • the strut 49 consists of the strut parts 48, 50, 52 which are articulatedly connected to one another or to the side frames 45, 47 and the one already mentioned Pipe piece 61, the movement of which is limited in two directions by the stops 54, 56.
  • the seat 17 is articulated at 15 on the chassis 11. This articulation is clearly visible in FIG. 2, but the chassis 11 and seat 17 are shown separately in an exploded view.
  • the seat 17 also consists of two side frames 18, 20. A fabric covering 22 extends between these side frames 18, 20. If the weight of the user acts on the seat 17 in the direction of the arrow 24, forces arise which have the tendency to bring the side frames 45, 47 closer together at the front. The movement of the side frames 45 and 47 towards one another remains limited, however, because it is prevented by the arrangement of the struts 49, 51 and the tensioning cables 53, 57 ', 57 ", 59', 59" shown. However, the chassis 11 is not completely stiff and can therefore twist somewhat if forces act on the chassis 11 as a result of unevenness in the floor. This has the advantage that even in such a situation, all four wheels 13, 14 of the wheelchair remain in contact with the ground.
  • the user of the wheelchair moves from the seat 17 to a car seat, he can release the lock 61 on the respective strut 25, 29, 51 and then pull in the direction of the arrow 27, 29, 31.
  • the chair is then foldable, see the two side frames 45, 47 can be approximated. Now that the wheelchair is very light, the user can pick it up and stow it behind the car seat. Conversely, he is also able to take the wheelchair out of the car, with one hand being able to move one strut after the other in the direction of the arrows 27, 29, 31, and then after securing the knee joints with the tube pieces 61 to use the chair.
