Definitions

  • the invention relates to a wheelchair pulling device of the type specified in the preamble of claim 1.
  • the starting point is a removable, motor-driven train drive according to DE-OS 24 46 573.
  • a rigid, fork-shaped drawbar is connected on both sides to the wheelchair, with which a larger wheel serving to drive and steer the trailer is connected to a joint which can be rotated about an approximately vertical axis, and to a handlebar, for example as in a bicycle Exercise the steering movement is provided.
  • the only wheel used for propulsion and steering is driven by a gasoline engine via a friction roller, as is the case with known motorcycles.
  • Two extendable telescopic supports at the end of the fork drawbar are used for "parking".
  • a disadvantage of this known traction drive is, on the one hand, the fact that it has to be lifted like a wheelbarrow in the uncoupled state and can only be directed with both hands and even large swiveling deflections on the drawbar only produce small changes in direction of the device. This proves to be a problem for a wheelchair user if he himself wants to put the device out of the way or want to bring it towards him, since experience has shown that he already needs a hand to drive the wheelchair in such a process, or without driving the wheelchair cannot make wide swiveling and pushing movements.
  • the invention specified in claim 1 has for its object to provide a wheelchair traction device of the type mentioned, which can be easily disconnected and parked by the handicapped himself and which the wheelchair user can get back at any time so that he can easily couple it himself can, the traction device can already be driven and directed with one hand, if necessary using the drive motor.
  • the traction device can be coupled and uncoupled from this traction drive without auxiliary devices.
  • a single-armed drawbar is sufficient, which is provided on the device side with a rotatable joint which is blocked in certain end positions about the vertical and transverse axes, and on the wheelchair side with a suitable releasable clamping device on a suitable one Section at the front of a side part of the Wheelchair frame is connected.
  • a central connection is not possible with the usual wheelchairs.
  • a double-armed fork drawbar is only necessary under extreme loads and is avoided if possible due to additional handles when coupling and uncoupling.
  • the device In the case of two driven wheels, these are coupled to the electric motor via a differential gear, or in special cases the wheels are driven by two separate motors.
  • the device In the decoupled state, the device stands on at least three points, preferably on four wheels, and is moved in a straight line either by pushing by hand or by actuating the speed controller. It is only pressed down and swiveled on the steering handle for directing purposes, which means more economical handling from the wheelchair, especially since small swivel deflections produce larger changes in angle.
  • the non-driven wheels are swiveled up by the load on the drawbar by the wheelchair and do not touch the ground, so that steerability is ensured.
  • the drawbar is swiveled by 180 * around a vertical axis of rotation.
  • a hinge that can be locked in any position in the crank of the steering bracket and directly above the engine cowling allow individual adjustment until it is fully folded up for minimal space requirements.
  • the end of the drawbar on the wheelchair side also has a restricted pivoting possibility about the transverse axis, which permits a level shift.
  • Overcoming a curb edge is similar to that described above.
  • the steering bracket is already tilted over when the drive wheels are still in front of the curb.
  • the tractor is first levered to the level of the curb.
  • the entire team is then moved forward in a known manner by manual operation moves until the tractor is completely on the curb.
  • the end position of the rotatability in the transverse axis is reached at the end of the drawbar on the implement side.
  • the rest of the process takes place as previously described for the version with larger drive wheels. In both cases, the process - taking advantage of the driving momentum - can take place in the auxiliary tires without manual assistance.
  • a wheelchair pulling device which is simple in construction and easy to use and which overcomes a step, e.g. a curb, equipped with reasonable effort, can be assumed from the usual wheelchairs with small front wheels and large rear wheels, in which the problem of overcoming a step is concentrated on the front wheels because the rear wheels are large enough are to overcome a curb without too much effort without additional aids.
  • a lever applicable Roll 'chair-pulling device consists of a preferably two-axis and four-wheeled tractor with wheels of relatively small diameter of the offerednord ⁇ voltage of the wheelchair front wheels.
  • this tractor and an essentially rigid connector to the wheelchair apart from two joints the latter can be lifted onto a curb.
  • the two joints on the connector are limited in their swivel range.
  • One is near the tractor, preferably behind the rear de n attached and the other near the wheelchair front axle. It is thereby achieved that the wheelchair attachment with its front axle can be placed on curbs or elevations by means of a hand-operated lever end, pushing the lever end forward in the direction of travel raises the wheelchair at the front.
  • the pivoting range of the joints can be limited by stops, of which at least the one located near the wheelchair accessory can be adjustable (or can also be designed as a breakable resting point) in order to be able to temporarily expand the pivoting range when overcoming an extreme obstacle.
  • the limitation of the swivel range also means that the front wheels of the wheelchair traction device are raised and the manually operable lever end, which can also be designed as a handlebar, remains particularly convenient in the wheelchair driver's access area when the vehicle is on level ground.
  • Traction device together with the fixed steering linkage enables a lever arrangement, the steering linkage forming a long lever and the connection to the front part of the wheelchair forming a short lever.
  • the front axle represents the fulcrum of the lever.
  • the arrangement of the articulation behind the rear axle also means that the latter can also serve as a fulcrum.
  • the front axles of the wheelchair and tractor can be alternately raised by appropriate movements of the steering linkage. If, according to 1. when overcoming steps, the rear wheels have been "levered” around the front axles as a fulcrum to the level of the elevated step and rest there, the rear axle can subsequently serve as a fulcrum for "levering up" the wheelchair front axle.
  • the stop for the first articulated connection located on the pulling device keeps the front wheels raised on level ground and, if a second articulated connection is present, enables the first articulated connection to form a rigid continuation of the lever acting on the front part of the wheelchair. It holds the towing device in an inclined position so that driving can also be carried out with the handlebars released. In addition, when braking with the towing device, the moment that moves the handlebar forward need not be recorded by hand.
  • the second, rear articulated connection enables the traction device to be lowered when the front articulated connection is limited by a stop, and the scope for inclining the traction device when the front wheels are raised is also increased.
  • Both joint connections movable about the different transverse axes have the effect that the front axle of the traction device can be raised by tilting over the rear axle without the front axle of the wheelchair having to be lowered accordingly.
  • the (possibly unnecessary) stop for the second joint connection increases the lever ratio for the attack of the traction device on the front part of the wheelchair until the limitation for the first joint connection takes effect. This ensures that in normal operation, when the team is in the plane and the front part of the towing device is raised (with the second articulated connection at the stop), the resulting strokes are limited when driving on bumps that occur because the towing device is coupled to the wheelchair with a "long lever".
  • the rear joint connection at the stop and the front joint are effective in the case of advantageous dimensioning.
  • the wheelchair is thus coupled to the traction device by means of a "short lever" and the front wheelchair axle can be lifted without significant effort after the traction device has reached the curb.
  • OMPI dimension the stops so that, at the usual height of a curb, the rear joint only reaches its stop when the rear axle of the traction device has already been raised substantially onto the curb, so that the "short lever" for lifting the wheelchair “With regard to the point of contact of the rear wheels, it acts as a momentary pole when the front wheels are already raised again.
  • the unit consisting of wheelchair and traction device forms a team which, in addition to the pivot bearing required for control about a vertical axis, has a further pivot option about a transverse axis which, in conjunction with the existing stops, depends on the bending angle taken at two different points is effective.

This is of particular importance because in this phase the wheelchair user only has to exert a relatively small force in the direction of arrow 18. Approximately from the position shown, the drive of the wheels 6 then takes over a large proportion of the forces required to overcome the step 16 by the wheelchair. It may be expedient if the wheelchair user pushes the wheelchair somewhat towards the step 16 with the aid of a grip ring attached to the wheelchair rear wheel 3, so that the wheels 6 can transmit their driving forces to the edge of the step 16.
