7.9.2 Rear wheel with one-handed operation (double push rings)
The wheel set for one-handed operation allows hemiplegics or unilateral amputees for example to operate the
wheelchair with one hand (see fig. 41).
•
Using the outer and inner handrim together: Both wheels are driven together. The wheelchair drives
straight ahead.
•
Using only the outer handrim:
Only the drive wheel is moved. The wheelchair can be steered with forward,
stopping or backward movements of the handrim.
The one-hand drive is supplied with special quick-release axle mountings and a telescoping rod.
Using drive wheels for one-handed operation
1) Use your thumb to press the push-button on the quick-release axle.
2) Install the drive wheels for the one-hand drive in the quick-release axle mountings (see fig. 42) and lock them
by turning the locking bolt 90° (see fig. 43).
3) The quick-release axles must not be removable after releasing the push-button.
4) Insert the telescoping rod. To do so, set one side of the telescoping rod onto the wheel pivot protruding from
the inside of the quick-release axle mounting (see fig. 44).
5) Compress the telescoping rod and set the other end of the rod onto the second wheel pivot.
Removing drive wheels for one-handed operation
1) Compress the telescoping rod and remove it (see fig. 44).
2) Open the locking mechanism on the quick-release axle. To do so, turn the locking bolt by 90° (see fig. 43).
