Abstract (en)
[origin: GB2573161A] A floor treatment machine 10 comprises a base portion provided with and supported by at least one rotatable work head for treating the floor, a handle portion 12 for steering or guiding the machine along a working direction of travel and adapted to be pivotable with respect to the base portion, floor-engaging wheel means 18 for supporting the handle portion 12, the wheel means 18 being coupled to the base portion by a linkage 17 which permits vertical travel of the base portion and associated work head or heads with respect to the wheel means 18, but which provides transverse constraint to limit or prevent yawing of the base portion with respect to the wheel means 18, wherein a lower region of the handle portion 12 is pivotably connected to the wheel means via an articulated joint, the arrangement being such that the handle portion 12 may be manipulated to act on the wheel means 18 so as to yaw steer the wheel means 18, wherein a handle pivot lock mechanism (44, 46, 47, fig 2) is provided in which the adoption of a predetermined handle portion orientation permits one or more locking feature to act on one or more corresponding constraint feature so as to prevent pivoting movement of the handle portion with respect to the base portion.
