Abstract

A patient support apparatus comprising a support frame and a patient support deck operatively attached to the support frame. The patient support deck has at least one deck section arranged for movement relative to the support frame. An actuator is arranged to move the deck section between an initial configuration and one or more raised configurations relative to the support frame. A link supports the deck section for movement with respect to the support frame. The link has a first end pivotally attached to the support frame, a second end pivotally attached to the deck section, and a protruding stop formed between the first end and the second end arranged to abut the deck section so as to prevent the actuator from moving the deck section beyond a maximum raised configuration.

First claim

What is claimed is:

1. A patient support apparatus comprising:
a support frame;
a patient support deck operatively attached to said support frame and having at least one deck section arranged for movement relative to said support frame;
an actuator arranged to move said at least one deck section between an initial configuration and one or more raised configurations relative to said support frame; and
a link supporting said at least one deck section for movement with respect to said support frame, said link having a first end pivotally attached to said support frame, a second end pivotally attached to said at least one deck section, and a protruding stop formed between said first end and said second end arranged to abut said at least one deck section so as to prevent said actuator from moving said at least one deck section beyond a maximum raised configuration.

2. The patent support apparatus as set forth in claim 1 , wherein said actuator is a linear actuator disposed in force-translating relationship between said at least one deck section and said support frame.

3. The patient support apparatus as set forth in claim 1 , wherein said link is pivotally attached to said support frame about a first frame axis and pivotally attached to said at least one deck section about a first deck axis.

4. The patient support apparatus as set forth in claim 3 , comprising a pair of links pivotally attached to said support frame about said first frame axis and pivotally attached to said at least one deck section about said first deck axis.

5. The patient support apparatus as set forth in claim 3 , further comprising a bar pivotally attached to said support frame about a second frame axis and pivotally attached to said at least one deck section about a second deck axis.

6. The patient support apparatus as set forth in claim 5 , wherein said first frame axis is spaced from said second frame axis at a frame axis distance, said first deck axis is spaced from said second deck axis at a deck axis distance, and said frame axis distance is greater than said deck axis distance.

7. The patient support apparatus as set forth in claim 5 , comprising a pair of bars pivotally attached to said support frame about said second frame axis and pivotally attached to said at least one deck section about said second deck axis.

8. The patient support apparatus as set forth in claim 1 , wherein said at least one deck section comprises a deck platform and a deck frame supporting said deck platform for concurrent movement between said configurations with said protruding stop of said link abutting said deck frame when said at least one deck section is in said maximum raised configuration.

9. The patient support apparatus as set forth in claim 1 , wherein said protruding stop of said link is arranged closer to one of said first end and said second end than to the other of said first end and said second end.

10. The patient support apparatus as set forth in claim 1 , wherein said protruding stop of said link has a rounded profile arranged for abutment with said deck section in said maximum raised configuration.

11. The patient support apparatus as set forth in claim 1 , wherein said protruding stop of said link has a notched profile arranged for engagement with said deck section in said maximum raised configuration.

12. The patient support apparatus as set forth in claim 1 , wherein said at least one deck section is further defined as a back section.

13. The patient support apparatus as set forth in claim 1 , wherein said at least one deck section is further defined as a leg section.

14. The patient support apparatus as set forth in claim 1 , wherein said protruding stop is formed integrally with said link between said first end and said second end.

15. The patient support apparatus as set forth in claim 1 , wherein said link has a mirrored profile defined longitudinally between said first end and said second end.

16. The patient support apparatus as set forth in claim 15 , wherein said link has a first protruding stop arranged adjacent to said first end and a second protruding stop arranged adjacent to said second end with one of said protruding stops abutting said at least one deck section in said maximum raised configuration.

17. The patient support apparatus as set forth in claim 15 , wherein said link has a symmetric profile between said first end and said second end.

18. The patient support apparatus as set forth in claim 17 , wherein said link has a first pair of opposing protruding stops arranged adjacent to said first end and a second pair of opposing protruding stops arranged adjacent to said second end with one of said protruding stops abutting said at least one deck section in said maximum raised configuration.

19. The patient support apparatus as set forth in claim 1 , wherein said link has a generally C-shaped profile between said first end and said second end.

20. The patient support apparatus as set forth in claim 1 , wherein said link has a generally I-shaped profile between said first end and said second end.

21. A patient support apparatus comprising:
a support frame;
a patient support deck operatively attached to said support frame and having at least one deck section arranged for movement relative to said support frame;
an actuator arranged to move said deck section between an initial configuration and one or more raised configurations relative to said support frame; and
a plurality of links supporting said deck section for movement with respect to said support frame, each of said links having a first end pivotally attached to said support frame and a second end pivotally attached to said deck section, with at least one of said links having a stop formed between said first end and said second end arranged to abut said deck section so as to prevent said actuator from moving said deck section beyond a maximum raised configuration.

22. A patient support apparatus comprising:
a support frame;
a patient support deck operatively attached to said support frame and having a back section arranged for movement relative to said support frame and a leg section arranged for movement relative to said support frame;
a first actuator arranged to move said back section between an initial configuration and one or more raised configurations relative to said support frame;
a second actuator arranged to move said leg section between an initial configuration and one or more raised configurations relative to said support frame;
a back link supporting said back section for movement with respect to said support frame, said back link having a first end pivotally attached to said support frame, a second end pivotally attached to said back section, and a protruding stop formed between said first end and said second end arranged to abut said back section so as to prevent said first actuator from moving said back section beyond a maximum raised configuration; and
a leg link supporting said leg section for movement with respect to said support frame, said leg link having a first end pivotally attached to said support frame, a second end pivotally attached to said leg section, and a protruding stop formed between said first end and said second end arranged to abut said leg section so as to prevent said second actuator from moving said leg section beyond a maximum raised configuration.
