Abstract
An upright surface treating appliance includes a main body and a cleaner head connected to a yoke. The main body is rotatable relative to the yoke about a first axis for movement between an upright position and a reclined position. A stand is moveable relative to both the main body and the yoke, between a supporting position for supporting the main body in its upright position, and a retracted position. The stand is biased towards its retracted position by a spring. An actuator is rotatable about a second axis spaced from the first axis and has a set of teeth which meshes with a profiled surface to drive movement of the stand towards its supporting position against the biasing force of the torsion spring. A drive member drives rotation of the actuator about the second axis as the main body is moved from a reclined position to an upright position.
