1. A patient support apparatus comprising:
a base arranged for movement over a floor surface, the base including a base frame;
a support frame with a patient support deck disposed on the support frame;
a lift assembly to move the support frame relative to the base in a vertical direction, the lift assembly comprising a lift member having a lift leg extending between a first end section and a second end section, the first end section of the lift leg movably coupled to the base frame for movement relative to the base during the lifting or lowering of the support frame, and the second end section of the lift leg pivotally connected to the support frame at a fixed pivot axis for pivoting relative to the support frame; and
a guide fixed to the base frame and arranged to guide the movement of the first end section of the lift leg when the lift leg pivots about the fixed pivot axis, the guide configured so that the first end section is displaced in the vertical direction relative to the base while being guided by the guide in order to lift or lower the lift leg relative to the base in the vertical direction, wherein the first end section is displaced away from the floor surface in the vertical direction as the lift assembly lifts the support frame relative to the base.
