Abstract

A patient support apparatus includes a frame having a head end and a foot end. A support arm is operably coupled to the head end of the frame. A cord is coupled to the support arm. A user interface housing is operably coupled to the cord and configured to retain a user interface. The user interface housing includes a locking body coupled to a body of the user interface housing and has a flange configured to engage an edge of the user interface. A latch mechanism includes a flexible body coupled to a rear side of the locking body. The latch mechanism is configured to selectively secure the locking body in a position. A shelf is coupled to a lower portion of the body of the user interface housing. The shelf has stoppers operably coupled to the shelf. The stoppers are adjustable along a horizontal plane to define different widths.

First claim

What is claimed is:

1. A user interface housing for a patient support apparatus comprising:
a body including an upper portion and a lower portion;
first and second ribs extending between the upper portion and the lower portion, the first and second ribs defining first and second channels, respectively; and
a locking body slidably disposed between the first and second ribs, the locking body including a latch mechanism configured to secure the locking body in position, wherein the locking body defines an access notch configured to receive a tool for selectively releasing the latch mechanism, and wherein the access notch is positioned on an upper end of a rear side of the locking body.

2. The user interface housing of claim 1 , wherein the locking body includes a flange defining a recess configured to retain an upper edge of a user interface.

3. The user interface housing of claim 1 , wherein the latch mechanism includes a flexible body comprising:
a first projection disposed adjacent a first aperture defined by the locking body;
a second projection laterally spaced from the first projection and disposed adjacent a second aperture defined by the locking body; and
a connecting portion, wherein the connecting portion couples the first and second projections.

4. The user interface housing of claim 3 , wherein the first and second projections move to a retracted position relative to the first and second apertures, respectively, upon downward movement of the connecting portion.

5. The user interface housing of claim 4 , wherein the locking body is configured to slide between the upper portion and the lower portion when the first and second projections are in the retracted position.

6. The user interface housing of claim 3 , further comprising:
a plurality of teeth disposed within the first and second channels, respectively, each of the first and second projections is configured to engage at least one tooth surface when in an extended position.

7. The user interface housing of claim 1 , further comprising:
a shelf disposed at the lower portion of the body; and
first and second stoppers operably coupled with the shelf, wherein the first and second stoppers are configured to retain a lower edge of a user interface within the shelf.

8. The user interface housing of claim 7 , wherein the first and second stoppers are adjustable on the shelf along a horizontal plane to define different widths.

9. The user interface housing of claim 1 , wherein the latch mechanism includes a flexible body coupled to the rear side of the locking body.

10. The user interface housing of claim 9 , wherein the flexible body includes:
first and second body portions laterally spaced from one another and extending along the rear side of the locking body; and
first and second projections laterally spaced from one another on opposing sides of the locking body and extending outward from the first and second body portions and toward first and second apertures, respectively, defined by the locking body.

11. The user interface housing of claim 10 , wherein the flexible body includes:
a connecting portion including first and second arcs coupled to the first and second body portions, respectively, the connecting portion configured to be engaged by the tool to, consequently, withdraw the first and second projections from the first and second apertures to a retracted position.

12. The user interface housing of claim 9 , further comprising:
a plurality of teeth disposed within the first and second channels, respectively, each of the first and second projections have angled edges that engage sloped surfaces of the plurality of teeth to form a pawl, and wherein, in an extended position, the first and second projections extend outwardly from the first and second apertures to engage the plurality of teeth and catch on sloped edges to prevent motion toward the upper portion of the body.

13. The user interface housing of claim 1 , further comprising:
a shelf disposed at the lower portion of the body.

14. The user interface housing of claim 13 , wherein the shelf includes a first shelf portion and a second shelf portion, each of the first and second shelf portions extending upwards to retain an edge of a user interface.

15. The user interface housing of claim 1 , wherein the body includes a handle that extends from the upper portion to the lower portion.
