Definitions

  • the invention relates to a collapsible wheelchair for the disabled with a floor assembly, which has castors at the corner points, with a seat with a backrest, which consists of a fixed seat frame and a foldable down about an axis arranged at the front edge of the seat, with a between the Floor assembly and the seat arranged support body, which has a rear pair of struts, which is articulated to the rear area of the floor assembly and the seat, the seat on the rear pair of struts is horizontally displaceable and the articulated axes are arranged transversely to the plane of symmetry of the wheelchair, which in the unfolded position of the wheelchair protrudes approximately vertically from the lifting group, and which can be locked in a folding position running approximately parallel to the floor group, and with at least one roller arranged on the rear edge of the seat frame with an axis transverse to the symmetry plane of the wheelchair.
  • collapsible wheelchairs are particularly needed when using vehicles - land, air and water vehicles - by disabled people who cannot use their own disabled wheelchair, which may have been individually designed for them, in the passenger compartments of these vehicles due to the cramped conditions.
  • this collapsible wheelchair is required to enable the disabled to use the vehicle toilets, which, again due to the limited space, would not be possible even if the disabled could otherwise use their own wheelchair.
  • this wheelchair should also be collapsible so that it is easy to stow away. It must be required, both for reasons of manageability and the dead weight to be carried, that such a wheelchair is light in weight, but very stiff in the working position and also easy to assemble and disassemble.
  • two non-round stand tubes are folded up from a base group provided with castors, and their length can be telescopically changed by means of a hydraulic system.
  • the seat with backrest is built up over a pair of longitudinal rails, so that the seat can be adjusted both in height and moved in the longitudinal direction.
  • the seat itself consists of a seat frame with a foldable middle part, so that after using this middle part, the seat can be moved back over the toilet to use the toilet, so that the disabled do not leave the place on the wheelchair, but without help Can use the toilet with this wheelchair.
  • an axis is provided between the seat and the backrest, as well as between the seat and the stand tubes or the pair of rails arranged there, which is arranged transversely to the axis of symmetry of the wheelchair and which places the backrest on the seat and after the stand tubes have been pivoted away allowing the seat plate to be placed on the floor assembly.
  • a disadvantage of this known wheelchair is that the use of the single pair of uprights, as well as the use of the rails for moving the seat, requires a very stable and thus also heavy construction, so that the seat, together with the necessary hydraulic device, becomes very heavy and is therefore difficult to handle.
  • This difficult handling applies not only to the assembly and disassembly of the wheelchair, but also to the manipulations that have to be carried out by the disabled himself, especially when using the toilet.
  • the invention has set itself the task of specifying a wheelchair of the aforementioned type, which is light in weight and yet so stable that it meets all the requirements to be placed on it, which is easy to use and which is easy to use even by a disabled person necessary manipulations.
  • the seat frame in the position in which the seat is located above the floor assembly is supported with its rear edge on the rear pair of struts and in that the support body has a front pair of struts that have one end of each strut is articulated on the front edge of the seat frame and with the other end of each strut perpendicularly and below about half the seat frame depth to the floor assembly, the articulated axes being arranged transversely to the plane of symmetry of the wheelchair.
  • the toilets for example in aircraft and land vehicles, are also designed with fixed struts on the side walls of the toilet cubicles, which allow the seat panel to be pushed back and forth.
  • the pivoting of the seat plate can in turn be carried out by pivoting the front pair of struts, again reaching the end position of the seat plate is supported by the fact that it is pulled into this end position by gravity.
  • This not only has the advantage that this end position is safely reached, but the weight loading the seat can now also be used to guide the lowered middle part of the seat up and into its end position parallel to the seat plate and to lock it there.
  • this seat middle part that is to say folding down and returning to the seat plane level, presents very great difficulties, difficulties which cannot be mastered by most disabled people.
  • this seat center part is automatically folded down when the seat plate is moved back and likewise, in connection with the forward movement of the seat plate, is guided back into the end position without any special manipulations by the disabled.
  • the rear pair of struts is a guide rail for the seat middle part provided on both sides with guide bolts at the free end, so that the seat middle part on these struts sink down by means of its guide bolts, i.e. release the seat plate for toilet use and by pushing the seat frame forward, this seat plate again, again guided by the guide bolts running along the rear pair of struts, can close.
  • the pivoting movement of the front pair of struts ensures that the seat plate always moves into its end position and generally remains there, but it is nevertheless advisable to lock the seat plate in these end positions.
  • this can be carried out in such a way that a locking bolt attached to the struts of the rear pair of struts and in each case a guide bolt of the seat middle part comprising a locking claw is attached to both sides of the rear edge of the seat frame. With this locking claw, the seat plate for transporting the disabled on the wheelchair is locked.
  • a lock can be provided on the front edge of the seat frame in order to fix the seat plate in this position even in the retracted end position. It is very useful in this case to make the locking claws self-latching in order to save the handicapped person the trouble of locking the locking claw.
  • both the seat frame and the seat middle part can be made of, optionally reinforced, plastic, since these parts rest securely on the front pair of struts and on the roller lying on the toilet during longitudinal displacement, i.e. mechanically hardly be burdened. This makes it possible to easily carry out these structural parts in terms of weight.
  • two support struts pointing downwards / forwards in the working position are to be articulated in the center on the front edge of the seat frame, which end feet support a footrest.
  • the distance between the two support struts should be slightly smaller than that of the struts of the front pair of struts so that these support struts together with the footrest can be retracted between the struts of the front pair of struts when the wheelchair is folded.
  • the footrest is expediently designed like a shovel, ie it consists of a support plate, the side edges and the rear edge of which are bent up, as a result of which the feet of the disabled are certainly prevented from slipping off from this foot support or from this support plate.
  • a support bracket bridging the distance from the support plate to the floor in a disconnected position is pivotably attached below the support plate.
  • This support bracket should be appropriately attached so that it goes to the rear. can be swiveled so that the wheelchair cannot be moved when the floor is uneven.
  • the articulation axis on the seat frame for the front strut pair and / or for the middle seat part and / or for the support struts is advantageously designed as a handle for the folded wheelchair.
  • a front strut pair 3 and a rear strut pair 4 are articulated to a floor assembly 1, at the corner points of which two steering wheel pairs 2 are attached.
  • the struts of the rear pair of struts 4 are attached to pillars 5 which protrude from the floor assembly 1.
  • the struts of the pair of struts 3 are articulated directly to the floor assembly 1, for example when soldering through half the land of a seat plate 6 which is supported by the strut pairs 3, 4.
  • the struts of the pair of struts 3 are articulated on the front edge of the seat plate 6; at the rear edge of this seat plate 6, it is supported on the end points of the struts of the pair of struts 4.
  • a transverse roller 7 is provided, which is arranged in a slot 8 in a height-adjustable manner. With this height adjustment, the transverse roller 7 can also be inserted at a slight angle in order to be able to compensate for unevenness in the toilet surface or the floor in front of it.
  • a terminal hump 9 of the seat plate 6 is the pivot point for a backrest 10 with pivotable armrests 11.
  • Support struts 12 are articulated on the front edge of the seat plate 6, which support a support plate 13, which serves as a footrest.
  • Lockable locking blocks 15 are also provided on the floor assembly 1 and are used to fix the wheelchair.
  • the seat plate 6 To use a toilet 16 (dash-dotted lines in Fig. 2), the seat plate 6 must be able to be moved backwards, like that; 2 can be seen. For this purpose, the locking of the seat plate 6 with the struts of the strut pair 4 is released by buttons 17, so that now the seat plate, which rests with the rear roller 7 on the upper edge of the toilet seat 16, can be moved to the rear, the struts moving of the pair of struts 3, as in Fig. 2 indicated by dash-dotted lines, swivel.
  • This pivoting has the advantage that the seat plate 6 is lowered slightly in each of the end positions, ie it moves with certainty into this end position.
  • a seat middle part 18 is also released by pressing the button 17, whereby this seat middle part 18, sliding with guide bolts 19 on the struts of the pair of struts 4, can reach the position shown in FIG. 2.
  • the guide bolts 19 slide on the back of the struts of the pair of struts 4, so that the seat middle part 18 is guided or pulled back into its previous position.
  • an adjustable stop 20 is attached, which ensures the exact start of the toilet, so that the transverse roller 7 rests on the toilet surface, so the seat plate 6 can be moved without difficulty.
  • Fig. 4 the wheelchair according to the invention is shown in a folded state.
  • these support struts 12 are retracted between the struts of the strut pair 3 and then, after releasing the lock between the seat plate 6 and the struts of the strut pair 4, the seat plate is lowered onto the floor assembly 1.
  • the backrest 10 is placed on the seat plate 6 and then the struts of the pair of struts 4 are placed on the package and locked in this position.
