Overview One-Hand Aids
Double handrim
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.
One-hand steering
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.
One-hand brake
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.
