Abstract
An auxiliary drive device for a wheelchair has at least one freely pivotable electrically driven drive wheel and a coupling mechanism for coupling the auxiliary drive device to the wheelchair. The coupling mechanism includes a movable locking element which is movably supported in the coupling mechanism. The movable locking element can be in a locking position in which it causes locking in a positive-locking manner so that the auxiliary drive device is coupled to the wheelchair and, by operation of a handle, the locking element can be moved in a release position in which uncoupling of the auxiliary drive device from the wheelchair is possible.
