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.
Claims10
An auxiliary drive device for a wheelchair, comprising:
- at least one electrically driven drive wheel;
- an electronic control unit for controlling the functions of the auxiliary drive device;
- a coupling mechanism for coupling the auxiliary drive device to a wheelchair;
- and
- an operating satellite for controlling the auxiliary drive device, the operating satellite being adapted to be attached to the wheelchair and comprising:
- an operating satellite control portion and an operating satellite mounting element;
- a display device provided on the outer side of the operating satellite and displaying information regarding operational conditions of the auxiliary drive device;
- an operating satellite control unit having electric and electronic components and adapted to perform bidirectional communication between the operating satellite and said electronic control unit for controlling the functions of the auxiliary drive device,
- wherein the display device is designed such that its arrangement on the operating satellite is adjustable such that it is made possible to adjust a position of the display device with respect to its visibility for a person sitting in the wheelchair in connection with a respective place of attachment of the operating satellite at the wheelchair,
- wherein the display device is attached to an outer circumference of the satellite control portion,
- wherein the outer circumference of the operating satellite control portion is rotatable with respect to the operating satellite mounting element and fixed in a position ensuring that the display device is within sight of the person sitting in the wheelchair, and
- wherein the display device and a control element of the operating satellite are adapted to rotate coaxially.
