MANUAL STAIR CLIMBER FOR A MECHANICAL WHEELCHAIR AND A METHOD OF USING A MECHANICAL WHEELCHAIR IN CONJUNCTION WITH SUCH MANUAL STAIR CLIMBER

摘要

The manual stair climber for a mechanical wheelchair includes a support structure (6) and a crawler track (7). The track (7) of the stair climber (5) and/or the entire stair climber (5) is shiftable and/or the rear wheel (4) of the wheelchair (10) is relocatable. The assembly of the stair climber (5) installed to the wheelchair (10) includes a transmission (8) which is connected to the track (7) of the stair climber (5), and to a torque transmitter (14). The stair climber (5), which is pivotably fixed to the wheelchair (10), includes a brake (11) which has a progressively increasing effect and is provided with a brake control element (5). The brake disc (12) of the brake (11) is attached to the stair climber (5) which is installed pivotably; and the brake caliper (13) of the brake (11) is attached to the wheelchair (10) and/or vice versa. In the configuration (II) for travelling across a grade-separated obstacle, the rear wheels (4) constitute a torque transmitter (14).
