Abstract

A person support apparatus includes a deck with a seat section, a leg section, and a back section. The back section is pivotally mounted to the seat section. The leg section has a proximal end pivotally mounted to the seat section and a cantilevered end spaced a first distance from its proximal end. The seat section, the leg section, and the back section are arranged to lie in a common plane when the deck is in a supine configuration to support a person in a supine position. A lift is mounted to the seat section of the deck, with the lift being configured to raise the deck relative to a supporting floor surface to a maximum height less than the first distance.

First claim

We claim:

1. A person support apparatus system comprising:
a deck having a seat section, a leg section, and a back section, and said back section and said leg section each pivotally mounted to said seat section and being reconfigurable between a cot configuration where said back section, said seat section, and said leg section are arranged to support a person in a supine position and a chair configuration where said back section and said leg section are angled relative to seat section to support a person in a sitting position;
a primary lift mounted to said deck to raise said deck relative to a supporting floor or ground surface from the supporting floor or ground surface to a first primary lift height and to a maximum second primary lift height wherein said leg section can be moved to said chair configuration without interference from the supporting floor or ground surface;
an auxiliary lift reconfigurable between a first configuration and a second configuration and positionable under said deck when said auxiliary lift is in said first configuration, said first configuration having a first auxiliary lift height, said second configuration having a second auxiliary lift height to raise said deck when positioned under said deck to a transport height, and said second auxiliary lift height being greater than said first auxiliary lift height and greater than said maximum second primary lift height, and said auxiliary lift operable to raise said deck and said primary lift off the supporting floor or ground surface when said auxiliary lift is reconfigured to said second configuration to raise deck and said primary lift to the transport height for loading the person support apparatus into an emergency vehicle; and
wherein when said auxiliary lift is reconfigured to said second configuration said auxiliary is configured to provide sole support for said deck.

2. The person support apparatus system according to claim 1 , further comprising a coupler mounted to or an engagement structure provided at said deck to releasably couple said deck to said auxiliary lift.

3. The person support apparatus system according to claim 2 , wherein said coupler or said engagement structure comprises a manually operable release or an electrically powered release.

4. The person support apparatus system according to claim 2 , wherein said coupler or said engagement structure comprises a pair of couplers, and said pair of couplers are mounted to said seat section of said deck.

5. The person support apparatus system according to claim 1 , wherein said deck further includes a foot section.

6. The person support apparatus system according to claim 1 , wherein said auxiliary lift is configurable between a third configuration having a third auxiliary lift height greater than said first auxiliary lift height and less than said second auxiliary lift height.

7. The person support apparatus system according to claim 1 , wherein said auxiliary lift comprises a pair of X-frames.

8. The person support apparatus system according to claim 1 , wherein said first primary lift height is greater than said first auxiliary lift height of said auxiliary lift to allow said auxiliary lift to be positioned under said deck when said auxiliary lift is in said first configuration.

9. The person support apparatus system according to claim 8 , wherein said primary lift includes one or more wheels, and said primary lift forms therein a space between said wheels sized to receive said auxiliary lift, wherein said deck may be moved over said auxiliary lift between said wheels of said primary lift when said deck is raised to a height equal to or greater than said first primary lift height and when said auxiliary lift is in said first configuration.

10. The person support apparatus system according to claim 8 , wherein said auxiliary lift includes one or more wheels, and said primary lift forms a space therein, said space sized to receive said auxiliary lift when said auxiliary lift is in said first configuration, wherein said auxiliary lift may be moved under said deck in said space when said deck is raised to a height equal to or greater than said first primary lift height and when said auxiliary lift is in said first configuration.

11. The person support apparatus system according to claim 8 , wherein said primary lift comprises two pair of legs, each pair of legs is pivotally mounted to said seat section of said deck for movement between a first orientation wherein said pair of legs are in a folded position and a second orientation wherein said pair of legs are in an unfolded position.

12. The person support apparatus system according to claim 11 , wherein each leg includes a wheel.

13. The person support apparatus system according to claim 2 , wherein said coupler or said engagement structure comprises a first coupler or a first engagement structure, said auxiliary lift includes a second engagement structure or a second coupler to be engaged by said first coupler or engage said first engagement structure on said deck.

14. The person support apparatus system according to claim 1 , wherein said auxiliary lift includes a base and a plurality of caster wheels mounted to said base, each caster wheel rotatably mounted to said base about a horizontal axis wherein said caster wheels may be moved between (1) non-operative positions wherein said caster wheels are positioned for disengagement from the supporting floor or ground surface and (2) operative positions wherein the caster wheels are positioned for engagement with the supporting floor or ground surface.

15. The person support apparatus system according to claim 1 , further comprising side rails mounted to said seat section.

16. The person support apparatus system according to claim 15 , wherein each side rail is pivotally mounted to said seat section and movable between a raised position and a lowered position.

17. The person support apparatus system according to claim 1 , wherein said back section is generally upright with respect to said seat section when in said chair configuration.

18. A person support apparatus system comprising:
a deck, said deck having a seat section, a back section, and a leg section, said back section and said leg section each being articulatable relative to said seat section, and said deck being reconfigurable between a cot configuration where said back section, said seat section, and said leg section are arranged to support a person in a supine position and a chair configuration where said back section and said leg section are angled relative to said seat section to support a person in a sitting position;
a primary lift mounted to said seat section of said deck to raise said deck relative to a supporting floor or ground surface to a height wherein said leg section can be pivoted relative to said seat section to said chair configuration without interference with the supporting floor or ground surface;
an auxiliary lift selectively positionable under said seat section of said deck and configured to lift said deck and said primary lift relative off the supporting floor or ground surface to raise said deck and said primary lift to a transport height for loading into an emergency vehicle;
a coupler mounted to (1) said deck or (2) said auxiliary lift; and
an engagement structure formed or mounted to the other of (1) said deck or (2) said auxiliary lift to cooperate with said coupler to releasably couple said deck to said auxiliary lift when said auxiliary lift is positioned under said seat section of said deck.
