Abstract

A patient support apparatus having a support structure with a primary support surface for a patient, and an extension manually movable by a user relative to the support structure from a stowed position to an extended position so that the extension provides auxiliary support for the patient in the extended position. A locking device is operable to releasably hold the extension relative to the support structure in the stowed position and the extended position. A release mechanism is operable to manipulate the locking device to release the extension for movement relative to the support structure, and is movable with the extension from the stowed position to the extended position.

First claim

What is claimed is:

1. A patient support apparatus comprising:
a base arranged for movement along floor surfaces;
an intermediate frame spaced above the base;
a patient support deck coupled to the intermediate frame and comprising a primary support surface for a patient;
an extension manually movable by a user relative to the intermediate frame from a stowed position to an extended position so that the extension provides auxiliary support for the patient in the extended position; and
a cable support having a first end connected to the intermediate frame, a second end connected to the extension, and a strip of flexible material extending between the first end and the second end and defining a cable retainer for retaining a cable between the first end and the second end to support the cable as the extension moves from the stowed position to the extended position.

2. The patient support apparatus of claim 1 , wherein the strip of flexible material of the cable support is arranged to flex such that the strip limits motion of the cable to two degrees of freedom as the extension moves from the stowed position to the extended position.

3. The patient support apparatus of claim 1 , wherein the strip of flexible material of the cable support has a generally rectangular profile extending between the first end and the second end.

4. The patient support apparatus of claim 3 , wherein the generally rectangular profile of the strip of flexible material defines:
a length defined in a longitudinal direction between the first end and the second end, and
a height defined in a vertical direction relative to floor surfaces; and
wherein the length is at least three times larger than the height.

5. The patient support apparatus of claim 3 , wherein the generally rectangular profile of the strip of flexible material defines:
a length defined in a longitudinal direction between the first end and the second end,
a height defined in a vertical direction relative to floor surfaces, and
a thickness defined in a lateral direction perpendicular to the longitudinal direction and perpendicular to the vertical direction; and
wherein the height is larger than the thickness.

6. The patient support apparatus of claim 5 , wherein the length is larger than the height.

7. The patient support apparatus of claim 1 , wherein the cable retainer of the cable support includes a plurality of openings for weaving the cable therethrough to support the cable.

8. The patient support apparatus of claim 1 , further comprising:
a locking device operable to releasably hold the extension relative to the intermediate frame in the stowed position and the extended position; and
a release mechanism operable to manipulate the locking device to release the extension for movement relative to the intermediate frame, the release mechanism being movable with the extension from the stowed position to the extended position.

9. The patient support apparatus of claim 8 , wherein the primary support surface has a head end and a foot end and the primary support surface extends longitudinally between the head end and the foot end; and
wherein the release mechanism includes a release handle longitudinally carried by the extension away from the foot end as the extension moves from the stowed position to the extended position.

10. The patient support apparatus of claim 9 , further comprising a second locking device, the locking devices being spaced apart and cooperable to releasably hold the extension relative to the intermediate frame in the stowed position and the extended position; and
wherein each of the locking devices comprises a locking element and the release mechanism is configured to manipulate the locking elements simultaneously to release the extension for movement relative to the intermediate frame.

11. The patient support apparatus of claim 10 , wherein the release mechanism is configured to manipulate the locking elements simultaneously to release the extension for movement relative to the intermediate frame upon one-handed operation of the release handle by the user.

12. The patient support apparatus of claim 10 , wherein each of the locking devices further comprises a biasing device, the biasing devices being arranged to bias the locking elements into engagement with one of the intermediate frame or the extension; and
wherein the release mechanism further comprises a pair of release members movable to disengage the locking elements from the intermediate frame to release the extension for movement relative to the intermediate frame.

13. The patient support apparatus of claim 12 , wherein the release mechanism further comprises a release actuator and a pair of links coupled to the release members, the release actuator being manipulable by the user to simultaneously move the links and the release members to disengage the locking elements from the intermediate frame.

14. The patient support apparatus of claim 13 , wherein the release actuator comprises a cross member having opposing ends rotatably coupled to the extension, a pair of arms fixed to the cross member and coupled to the links and the release handle; and
wherein the release handle is manually operable to rotate the cross member and the arms to move the links and the release members to disengage the locking elements from the intermediate frame.

15. The patient support apparatus of claim 8 , wherein the locking device is operable to engage one of the intermediate frame or the extension at a first discrete location when the extension is in the stowed position and at a second discrete location, longitudinally spaced from the first discrete location, when the extension is in the extended position.

16. The patient support apparatus of claim 1 , further comprising a footboard mounted to the extension to move with the extension from the stowed position to the extended position.
