Definitions

  • the invention relates to a collapsible wheelchair for the disabled, consisting essentially of a floor assembly with castors attached to the corner points, a support body for the seat and the seat with a backrest, in which on all essential individual parts the axes of pivot points required for folding transverse to the plane of symmetry of the Wheelchair are arranged and the seat is horizontally displaceable on the support body, the seat consists of a fixed seat frame and a middle part which can be folded down about an axis arranged at the front edge of the seat and at least one roller in an axis transverse to the plane of symmetry on the rear edge of the seat frame the wheelchair is arranged.
  • 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 demanded, both for reasons of manageability and the dead weight to be carried, that such a wheelchair is light in terms of weight, but in the working position is very stiff and also easy to assemble and disassemble.
  • two non-circular upright tubes are folded up from a base assembly provided with castors, the length of which 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 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 construct 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 support body of the wheelchair consists of two articulated brace pairs attached to the floor assembly, a rear brace pair which is in a working position projecting approximately perpendicularly from the floor assembly, in which the seat frame is supported with its rear edge on this brace assembly and can be locked in a folding position running approximately parallel to the floor assembly and a pair of front struts which are articulated forward / upward on the front edge of the seat frame, with a base point which is approximately half the depth of the seat frame.
  • 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 follow 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 it can now also be exploited that the load on the seat is 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.
  • the rear pair of struts is a guide rail for the seat middle part provided with guide bolts at both ends at the free end, so that the seat middle part descends on these struts by means of its guide bolts, thus releasing 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 a locking claw comprising a guide bolt of the seat center part are attached to both sides of the rear edge of the seat frame. With this locking claw, the seat plate for transporting the disabled person is locked on the wheelchair.
  • a lock can also 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 / verne in the working position are to be articulated in the center on the front edge of the seat frame, which end supports have 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 inserted between the struts of the front pair of struts when folding the wheelchair.
  • 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 prevented from slipping off this footrest or this support plate.
  • a support bracket bridging the distance from the support plate to the floor in the folded-up position is pivotably attached below the support plate.
  • This support bracket should be appropriately attached so that it nog backwards 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 center seat part and / or for the support struts is advantageously designed as a handle for the folded wheelchair.
  • a pair of front struts 3 and a pair of rear struts 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 in the case of the plumb line, by half the length of a seat plate 6 which is carried 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 struts pair 4 off.
  • a transverse roller 7 is provided, which is arranged in a slot 8 so that it can be adjusted vertically. By means of 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 in 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.
  • On the underside of this support plate 13 there is a support bracket 14 which bridges the distance between the underside of the support plate 13 and the floor. Both the support plate 13 and the support hill 14 are connected in an articulated manner to their structural parts in order to enable them to be folded up in the smallest space.
  • Lockable locking blocks 15, which are used to fix the wheelchair, are also provided on the floor assembly 1.
  • the seat plate 6 To use a toilet 16 (shown in broken lines in FIG. 2), the seat plate 6 must be able to be moved backwards, as can be seen from FIG. 2. For this purpose, the locking of the seat plate 6 with the struts of the pair of struts 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 becoming the Pair of struts 3, as indicated by dash-dotted lines in Fig .. 2, pivoting.
  • 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, as a result of which this seat middle part 18, with guide bolts 19 sliding on the struts of the strut pair 4, into that shown in FIG. 2 Location can get.
  • the guide bolts 19 slide on the rear of the struts, 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 approach to 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 inserted between the struts of the pair of struts 3 and then, after releasing the lock between the seat plate 6 and the struts of the pair of struts 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.
