Abstract

A pole attached to a hospital stretcher or the like for supporting an intravenous solution container. This pole has an improved collapsible construction attaching it to the stretcher so such pole does not interfere with any stretcher operation.

Claims

1. A collapsible pole assembly for connection to a patient carrying device comprising:

a shank pivotally connected to a supporting base;

a coupler longitudinally slidable along the shank;

a pole rigidly attached to the coupler to form a sliding unit, said pole being laterally offset from the shank and movable to different sides of the shank without movement of the supporting base; and

a lock on the assembly which is slidably engaged by the unit.

2. A collapsible pole assembly as set forth in claim 1, wherein the coupler can rotationally swivel on the shank.

3. A collapsible pole assembly as set forth in claim 1, wherein the pole has upper and lower sections telescopically joined together for altering the pole'"'"'s length.

4. A collapsible pole assembly as set forth in claim 1, wherein the lock includes a socket into which at least a portion of the sliding unit is received to firmly lock the pole in an upright position.

5. A collapsible pole assembly as set forth in claim 4, wherein the pole of the sliding unit has a lower end portion that is received in the socket.

6. A collapsible pole assembly as set forth in claim 1, wherein the shank has a limit stop to prevent disengagement of the shank and slidable coupler.

7. A collapsible pole assembly as set forth in claim 6, wherein the limit stop is a protruding pin anchored to the shank.

8. A collapsible pole assembly as set forth in claim 1, wherein the pole has a longitudinal axis and a hook support area offset in a first lateral direction;

and a hook attached to the hook support area and protruding in a second lateral direction, whereby the pole can be compactly stored along a rail of a patient carrying device without undue interference between the hook and such rail.

9. A collapsible pole assembly as set forth in claim 8, wherein the first and second lateral directions are approximately perpendicular to each other.

10. A collapsible pole assembly as set forth in claim 8, wherein the pole has a lower section anchored to the coupler and an upper section telescopically joined to the pole'"'"'s lower section;

and the offset hook support area is on the upper section.

11. A patient carrying device with a collapsible pole assembly wherein the improvement comprises:

a shank pivotally connected to such device;

a coupler longitudinally slidable along the shank;

a pole rigidly attached to the coupler to form a sliding unit, said pole being laterally offset from the shank and movable to different sides of the shank without movement of the patient carrying device; and

a lock on the assembly is slidably engaged by the unit.

12. A patient carrying device with a collapsible pole assembly, wherein the improvement comprises:

a base connected to the device;

a pole support pivotally connected to the base at a generally horizontal pivot axis;

a lock on the device for holding a pole in a generally vertical position during use; and

a pole connected to and longitudinally movable relative to the pole support to engage and disengage such lock, said pole being laterally offset from the pole support and movable to different sides of the pole support without movement of the patient carrying device.

13. A patient carrying device as set forth in claim 12, wherein the lock includes a socket.

14. A patient carrying device as set forth in claim 12, wherein the pole support has a longitudinal axis, and the pole is joined to a coupling structure that is coaxial with the pole support causing remaining portions of the pole to swivel about the pole support in an arcuate manner.

15. A patient carrying device with a collapsible pole assembly, wherein the improvement comprises:

a base;

a pole that is pivotally joined to the base by means of a coupling structure that is laterally offset from the pole with the coupling structure having a portion pivotally connected to the base at a generally horizontal pivot axis; and

a swivel joint on the assembly permitting the pole to move about a swivel axis to different sides of the swivel axis without movement of the base, which swivel axis has a nonparallel relationship to the pivot axis, whereby the pole can move relative to both axes in moving between a compact generally horizontal storage position and a generally vertical position.

16. A patient carrying device as set forth in claim 15, wherein the swivel and pivot axis are approximately perpendicular to each other.

17. A patient carrying device as set forth in claim 15, wherein the pole is connected to an offset structure that is coaxial with the swivel axis, whereby the pole swings in an arcuate motion about the offset structure.

18. A patient carrying device with a collapsible pole assembly, wherein the improvement comprises:

an elongaged pole;

a pivot member joining a bottom end portion of the pole to such device along a pivot axis that is generally horizontal;

said pivot axis being approximately perpendicular to a support rail of the device, whereby the pole can be pivoted to a generally horizontal storage position against such rail;

a laterally offset protruding hanger at an upper end portion of the pole, which offset hanger extends away from the rail so as not to interfere with the rail when the pole is in such generally horizontal storage position against the rail for compact nesting with such rail; and

lock means on the device for securing the pole in a generally vertical position during use.
