    Abstract: A patient support apparatus comprises a base and a support frame. The patient support apparatus also comprises a lift assembly that operates to lift and lower the support frame relative to the base. The lift assembly comprises lift members that extend and collapse to lift and lower the support frame. A timing link is pivotally connected to one of the lift members and pivotally connected to the base. Guides operate to guide movement of the lift members during operation. In some cases guided bodies coupled to the lift members move passively in the guides. In other embodiments, driven members coupled to the lift members move actively in the guides to cause lifting and lowering of the support frame.

    Abstract: A patient support apparatus for traversing objects supported on ground surfaces. The patient support apparatus comprises a patient support deck, and a base to support the patient support deck from the ground surface. At pair of caster wheel assemblies spaced from each other are coupled to the base for pivoting movement about respective pivot axes cooperating to define a reference plane. A frame guard coupled to the base defines first and second ramp surfaces each disposed at an angle relative to the reference plane. The first ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in a first direction. The second ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in an opposite, second direction.
