Person support apparatus
First Claim
1. A person support apparatus comprising:
- a person support frame for supporting a person support deck, the person support frame having two sides extending between a head end and a foot end; and
a support assembly for supporting the person support frame and moving it relative to a floor surface, wherein the support assembly comprises at least one leg assembly pivotally coupled at a first upper end portion to the person support frame and coupled at its second lower end portion to floor engaging means, and an actuator element operable to move the leg assembly and thereby move the person support frame relative to the floor, wherein at least one of the sides of the person support frame comprises an inverted substantially U-shaped channel element having a substantially continuous upper surface, two substantially continuous side surfaces connected at their top edges to the upper surface, and a downward facing opening between the bottom edges of the two side surfaces, and the first upper end portion of the leg assembly includes a guide or follower element arranged to contact and run along an inner surface of the channel element.

Abstract
A patient support apparatus includes a patient support frame for supporting a patient support deck, the patient support frame having two sides extending between a head end and a foot end, and a support assembly for supporting the patient support frame and moving it relative to a floor surface. The support assembly comprises two leg assemblies pivotally coupled at their first upper end portions to the patient support frame and coupled at their lower end portion to floor engaging means. The sides of the patient support frame each comprise inverted substantially U-shaped channel elements having a substantially continuous upper surface, two substantially continuous side surfaces connected at their top edges to the upper surface, and a downward facing opening between the bottom edges of the two side surfaces. The first upper end portion of the leg assemblies each include roller assemblies arranged to run inside the channel elements and engage and run along a channel between the bottom of the upper surface of the respective channel element and the bottom of the channel element.
