Definitions

  • the invention relates to a medical elevator (wheelchair) with a height-adjustable seat, the chassis of which is supported on two lateral rear wheels acting as drive wheels and on two lateral, smaller front wheels, each mounted in a wheel fork, the wheel forks being pivotable about towering axes.
  • Such an elevator known from DE-OS 32 27 365 can be driven by the handicapped by turning the large rear wheels with his hands.
  • the smaller front wheels act as steering wheels, they are arranged in the swiveling wheel forks and automatically adjust to the direction of travel desired by the disabled person by driving the two rear wheels evenly or differently.
  • each perforated plate having a plurality of insertion holes for the rear axles which are spaced apart in the direction of travel and in the vertical direction. This allows the desired height of the seat of the medical elevator to be set.
  • the invention is based on the object, the individual adaptability of the elevator to the possibilities of the disabled to increase, so that it, for example, regardless of the appropriate age in sports, games and leisure and also during normal driving, the most favorable height and inclination Seat can be adjusted or adjusted.
  • the medical elevator should therefore be suitable both in the sports sector and for those wheelchair users who still have low leg functions and can use them to drive them, for example by tripping. In this case, the driving and steering can take place at least partially with the legs.
  • the medical elevator should enable an individual choice of focus to optimize the rolling behavior with good tipping stability. Both the center of gravity height and the center of gravity distance from the pivot point must be changeable.
  • each wheel fork is arranged at the lower end of an inner control head tube, which is inserted in a height-adjustable manner in an outer control head tube fastened to the chassis, and in that the inner control head tube has at least one radial threaded bore and the outer one Control head tube is equipped with a plurality of radial through holes arranged one behind the other at intervals along the tube axis, through which a fastening device engaging in the inner control head tube is detachably inserted.
  • the height of the front support of the chassis can thus be adjusted or changed. This is associated with a change in the seat angle.
  • the use of a screw preferably enables the two tubes to be attached to one another in a particularly simple manner.
  • the screw can be inserted through a certain through hole of the outer control head tube in the radial direction and screwed into the threaded bore of the inner control head tube aligned with this through hole.
  • the fastening screw is removed and the threaded bore of the inner tube is brought into line with a higher through hole of the outer tube, in order to screw the fastening screw in again in this new position.
  • two threaded bores of the inner control head tube and the through holes of the outer control head tube are each arranged in pairs opposite one another along a common diameter. This results in an even more secure two-sided fastening of the two tubes to one another.
  • Each wheel fork is preferably attached to the lower end of a bearing axle which is rotatably mounted within the inner control head tube. This arrangement enables the front wheel to immediately adapt smoothly to the direction of travel imposed.
  • a hospital elevator according to the invention with a seat 10, a backrest 11 and two armrests 12 has a chassis with two identical lateral frames formed by tubular structures, a lower side rail 13 of a frame being connected to a front wheel 14 and a perforated plate 15 to a rear wheel 16 is.
  • the perforated plate 15 is provided with a plurality of insertion holes 17 which are spaced from one another in the direction of travel and in the vertical direction. They allow the insertion of a rear axle 18 of the Rear wheel 16 into a specific insertion hole 17 corresponding to the desired position.
  • Each front wheel 14 is mounted with a horizontal axis of rotation 19 in a wheel fork 20 which does not extend vertically from the axis of rotation 19, but extends upward at an acute angle. With its upper end, the wheel fork 20 is fastened to an upstanding bearing axis 21 which is rotatably mounted in an inner control head tube 22 which is detachably fastened to the chassis.
  • the arrangement of the front wheel 14 thus enables automatic adjustment to the desired direction of travel by rotating the bearing axis 21.
  • the upper end of the wheel fork 20 lies against a collar 23 of the bearing axis 21 and is fastened there by means of a nut 24 screwed onto the bearing axis 21. This collar 23 is located on the lower end face of the inner control head tube 22.
  • the inner control head tube 22 initially has an end bearing bore 25 for an axial bearing 26 of the bearing axis 21.
  • the bearing bore 25 is followed by a bearing bore 27 for a lower radial bearing 287 of the bearing axis 21, which bearing 28 can be a needle bearing.
  • a further bearing bore 29 for an upper radial bearing 30 of the bearing axis 21 is arranged in the inner control head tube 22.
  • the inner control head tube 22 is inserted from below into an outer control head tube 31 and fastened in a certain position with the aid of two fastening screws 32.
  • the inner control head tube 22 has the fastening screws 32 two threaded bores 33 arranged opposite one another on a pipe diameter. These are made to coincide with two corresponding through holes 34 in the outer control head tube 31.
  • the fastening screws 32 are therefore first inserted through the through holes 34 of the outer control head tube 31 and then screwed into the threaded holes 33 of the inner control head tube 22.
  • the through holes 34 are arranged in the longitudinal direction at intervals in the outer control head tube 31 in pairs, so that it is possible to select a specific pair of the through holes 34 for the threaded holes 33 of the inner control head tube 22 and to screw in the fastening screws 32. With the choice of this particular pair of through holes 34, the desired particular height of the outer steering head tube 31 above the front wheel 14 is determined.
  • the height of the outer control head tube 31 determines the height of the lower side member 13.
  • the outer control head tube 31 is adjustably fixed via a welded-on pivot lever 35.
  • the pivot lever 35 has a bore through which a horizontal pivot axis 36 extending in the transverse direction of the vehicle is inserted, which connects the pivot lever 35 to the lower side rail 13 here.
  • the pivot axis 36 can be, for example, a screw with a nut screwed on.
  • the pivoting lever 35 extending in the direction of travel shows at its front end an elongated hole 37 which extends in the pivoting direction, that is to say in the direction of an arc with the pivot axis 36 as the center.
  • a horizontal fastening screw 38 which extends in the transverse direction of the vehicle and which is inserted through one of a plurality of through holes 39 arranged one behind the other in the direction of travel.
  • the lower side rail 13 also has a plurality of through holes arranged one behind the other in the direction of travel for the pivot axis 36.
  • the pivot lever 35 can therefore be adjusted more or less far forward on the lower side rail 13.
  • the medical elevator according to the invention enables a large number of setting combinations, the setting corresponding to the insertion holes 17 of the perforated plate 15, the through holes 38 of the lower side rail 13 and the through holes 34 of the outer control head tube 31 being able to be carried out in small steps.
  • the wheelchair can therefore be adjusted to the most varied of desired seating positions.
