Overview One-Hand Aids
Here two handrims with different cross section dimensions are mounted on one side. The larger serves the common function of controlling the rear wheel on which it is mounted. But the smaller handrim drives the opposite rear wheel by transmission of a rigid axle. This way, using one single handrim steers the wheelchair into a curve, pushing both handrims moves the wheelchair in a straight direction. The rigid axle is easily detachable, so the wheelchair can be folded and transported as usual.
The one-hand steering device connects both front wheels by a steering rod. The rear wheels now only serve for pushing the wheelchair, the casters can be conveniently controlled with only one hand into any desired direction.
Ergonomical one-hand steering for children’s wheelchairs
This aid enables children to drive the rear wheels with their strong hand and to steer with their weaker hand. The biggest advantage of this solution is the direct steering approach, whereby the child turns its torso in a particular direction and the chair is steered in the same direction. In comparison to other one-hand steering wheels which work mirror inverted, this one-hand steering works intuitive and offers a playful design especially suitable for children.
The single-hand brake serves the same function as our standard wheel lock, but the control device is mounted on only one side. The control lever and the opposite wheel lock are connected by a Bowden cable. Due to a bigger lever, the effort needed to lock both brakes remains almost the same.
