Abstract

A hospital bed is supported on a Y-shaped base to facilitate the introduction of a C-arm for imaging a patient'"'"'s chest. Head guards are mounted on each side of the head end of the bed on linkages that permit the head guards to be swung toward the foot end of the bed to improve the positioning of the C-arm over the head end of the bed. The head panel has pivotable longitudinal edges to further improve the positioning of the C-arm over the head end of the bed. Pivotable longitudinal edges of the head and leg panels permit head and foot guards to be moved laterally inwardly to narrow the bed for transporting a patient.

said linkage means comprising both;

a parallelogram linkage including two spaced parallel links connected to said head guard and pivotal about vertical axes to permit said head guard to shift from a first position wherein said links extend toward the head of the bed through 180°

to a position wherein said links extend toward the foot end of the bed, and

a second parallelogram linkage pivotal about horizontal axes and connected to said first named parallelogram linkage to swing said head guard selectively upwardly and a farther distance toward said foot end and downward below the level of said bed frame.

3. A hospital bed comprising:

a base,

a bed frame mounted above said base,

a patient guard mounted on said bed frame alongside said bed,

a horizontally-swingable parallelogram linkage connecting said patient guard to said frame to permit said guard to be moved laterally inwardly in only a horizontal plane to reduce the lateral dimensions of the bed while maintaining protection of the patient,

means for latching said guard in said inward position.

4. A hospital bed comprising:

a base,

an elongated bed frame mounted on said base and having a head end,

a head guard,

a pair of spaced parallel vertically-swingable links, each pivotally mounted at one end on said head guard,

a pair of spaced parallel, only horizontally-swingable links, each pivotally mounted at one end on said bed frame, a bar pivotally mounted to the other ends of said horizontally-swingable links,

selective latch means connecting the other ends of said vertically-swingable links to said bar for latching said guard in an upper position, a lower position and an intermediate position.

5. A hospital bed comprising:

b base,

an elongated bed frame mounted on said base and having a head end,

a head guard,

a pair of spaced parallel vertically-swingable links, each pivotally mounted at one end on said head guard,

a pair of spaced parallel, horizontally-swingable links, each pivotally mounted at one end on said bed frame, a bar pivotally mounted to the other ends of said horizontally-swingable links,

selective latch means connecting the other ends of said vertically-swingable links to said bar for latching said guard in an upper position, a lower position and an intermediate position,

said latch means comprising;

a latch bar and an elongated plate to which the other ends of said vertically-swingable links are pivotally mounted,

means connecting said plate to said bar,

and a latch bolt on said plate engageable with said latch bar to hold said bar and links in upper and intermediate positions.

6. A hospital bed comprising:

a base,

an elongated bed frame mounted on said base and having a head end,

a head guard,

a pair of spaced parallel vertically-swingable links, each pivotally mounted at one end on said head guard,

a pair of spaced parallel, horizontally-swingable links, each pivotally mounted at one end on said bed frame, a bar pivotally mounted to the other ends of said horizontally-swingable links,

selective latch means connecting the other ends of said vertically-swingable links to said bar for latching said guard in an upper position, a lower position and an intermediate position,

said bed frame having a head frame upwardly-pivoted about an axis,

said latch means including an elongated plate pivotally mounted at its footward end on said bar on an axis aligned with said head frame axis when said guard is swung toward said head end,

means for removably connecting said latch means to said head frame to pivot said guard about said axes when said head frame is pivoted upwardly.

7. A hospital bed comprising:

a base,

an elongated bed frame mounted on said base and having a head end,

a head guard,

a pair of spaced parallel vertically-swingable links, each pivotally mounted at one end on said head guard,

a pair of spaced parallel, horizontally-swingable links, each pivotally mounted at one end on said bed frame, a bar pivotally mounted to the other ends of said horizontally-swingable links,

selective latch means connecting the other ends of said vertically-swingable links to said bar for latching said guard in an upper position, a lower position and an intermediate position,

said bed frame having a head frame upwardly pivoted about an axis,

said latch means including an elongated plate pivotally mounted at its footward end of said bar on an axis aligned with said head frame axis when said guard is swung toward said head end,

means for removably connecting said latch means to said head frame to pivot said guard about said axes when said head frame is pivoted upwardly,

said bed having a foot guard adjacent said head guard,

said head guard having a surface adjacent said foot guard which is curved on a radius whose center is said latch means axis, whereby said head guard will not interfere with said foot guard when it is upwardly-pivoted.

8. A hospital bed comprising:

an elongated frame having a head end and a foot end,

head guards mounted on said frame at the head end of said frame,

mattress supporting panels mounted on said frame,

longitudinal wings pivotally mounted on said panels and extending along the head end portion of said bed, said wings being pivotal independently of said head guards upwardly to reduce the lateral dimension of only the head end portion of said bed,

means for moving either of said raised head guards transversely inwardly into the space vacated by said wings as said wings are pivoted upwardly.

9. A hospital bed as in claim 8 further comprising:

means for latching said head guard inwardly to hold said wings in an upwardly-pivoted position.

10. A hospital bed comprising:
