Abstract

A patient care equipment support is transferable between a first device having a first coupling member and a second device having a second coupling member. The equipment support comprises an equipment supporting portion configured to support patient care equipment and a coupler coupled to the equipment supporting portion and having first and second clamps. The first clamp is configured to grip the first coupling member and the second clamp is configured to grip the second coupling member.

Claims

1. A patient care equipment support transferable between a first device having a first coupling member and a second device having a second coupling member, the equipment support comprising:

an equipment supporting portion configured to support patient care equipment, and

a coupler coupled to the equipment supporting portion and having first and second clamps, wherein the first clamp includes a first handle, the first clamp being configured to grip the first coupling member when the first handle is moved to a locking position, and wherein the second clamp includes a second handle, the second clamp being configured to grip the second coupling member when the second handle is moved to a locking position, the first and second handles moveable independently of one another,

wherein the coupler further includes a mounting block, a first link and a second link, the first clamp further includes a first jaw, the first handle coupled to a first side of the mounting block and the first link coupled to the first jaw and coupled to the first handle such that the first jaw moves between an opened position and a closed position as the first handle moves between a releasing position and the locking position, the second clamp further includes a second jaw, the second handle coupled to a second side of the mounting block and the second link coupled to the second jaw and coupled to the second handle such that the second jaw moves between an opened position and a closed position as the second handle moves between a releasing position and the locking position, and

wherein the coupler comprises a post that extends downwardly from the equipment supporting portion, and the mounting block is coupled to the post, and

wherein the first jaw is coupled to the first side of the mounting block for pivoting movement about a first pivot pin, the first handle is coupled to the first side of the mounting block for pivoting movement about a second pivot pin, and the first link has a first end coupled to the first jaw for pivoting movement about a third pivot pin, the first link has a second end coupled to the first handle for pivoting movement about a fourth pivot pin, the second jaw is coupled to the second side of the mounting block for pivoting movement about a fifth pivot pin, the second handle is coupled to the second side of the mounting block for pivoting movement about a sixth pivot pin, the second link has a first end coupled to the second jaw for pivoting movement about a seventh pivot pin, and the second link has a second end coupled to the second handle for pivoting movement about an eighth pivot pin.

2. The equipment support of claim 1, wherein the coupler comprises a post that extends downwardly from the equipment supporting portion, and the first and second clamps are coupled to the post on first and second sides of the post.

3. The equipment support of claim 1, wherein the first clamp is closeable to grip the first coupling member when the equipment support is carried by the first device, and the second clamp is closeable to grip the second coupling member, and the equipment support is transferable from the first device to the second device when the first clamp releases the first coupling member allowing the first device to move away from the second device.

4. The equipment support of claim 1, wherein the mounting block, the first jaw, the first handle, and the first link form a first four bar linkage, and the mounting block, the second jaw, the second handle, and the second link form a second four bar linkage.

5. The equipment support of claim 1, wherein the first coupling member of the first device comprises a first post that is configured to be received in a first post-receiving cavity defined by the first jaw and the mounting block when the first jaw is moved to the opened position, and the first post is clamped between the first jaw and the mounting block when the first jaw moves to the closed position after receiving the first post in the first post-receiving cavity in response to the first handle moving to the locking position.

6. The equipment support of claim 5, wherein a second post-receiving cavity is defined by the second jaw and the mounting block when the second jaw is moved to the opened position, and the second jaw moves to the closed position in response to the second handle moving to the locking position.

7. The equipment support of claim 6, further comprising a lock configured such that when a post is received in one of the post-receiving cavities and the associated handle is moved to the locking position, said post is locked to the equipment support coupler, and such that when a second post is received in the second of the post-receiving cavity, both of the handles are unlocked so that respective engagements of both posts and the equipment support coupler are releasable.

8. The equipment support of claim 7, wherein the lock comprises a first slider and a second slider which are both spring biased such that a first tab of the first slider projects into the second post-receiving cavity and a first hook of the first slider engages the third pivot pin to normally lock the first handle in the locking position and such that a second tab of the second slider projects into the first post-receiving cavity and a second hook of the second slider engages the seventh pivot pin to normally lock the second handle in the locking position.

9. The equipment support of claim 8, wherein, when the first post is received in the first post-receiving cavity, the first post engages the second tab to shift the second slider against a spring force to disengage the second hook from engagement with the seventh pivot pin to unlock the second handle.

10. The equipment support of claim 8, wherein each slider has two slots through which the first and fifth pivot pins extend so that the sliders can shift between their respective latching positions and unlatching positions.

11. The equipment support of claim 8, wherein the lock further comprises a spring that is situated in a state of compression between the first and second tabs to bias the first and second sliders in opposite directions so that the first tab projects into the second post-receiving cavity and the second tab projects into the first post-receiving cavity.

12. The equipment support of claim 6, further comprising a lock that is movable to the first side when the first handle is in the locking position to lock the first handle in the locking position and to lock the first jaw in the closed position and to unlock the second handle and the lock is movable to the second side when the second handle is in the locking position to lock the second handle in the locking position and to lock the second jaw in the closed position and to unlock the first handle.

13. The equipment support of claim 12, wherein the lock is not movable to the first side when the first handle is the releasing position and the lock is not movable to the second side when the second handle is the releasing position.

14. The equipment support of claim 1, wherein the equipment supporting portion comprises an upper cross bar, a lower cross bar, a pair of outer posts extending between the upper and lower cross bars adjacent to the opposite ends thereof and a central post extending between the upper and lower cross bars between the two outer posts, and the first and second clamps are coupled to a lower portion of the central post that extends below the lower cross bar.

15. The equipment support of claim 14, wherein each outer post comprises a first portion and a second portion that telescopes into and out of the first portion and a lock movable between a releasing position allowing the second portion to telescope into and out of the first portion and a locking position preventing the second portion from telescoping relative to the first portion.

16. The equipment support of claim 15, wherein each outer post further comprises a plurality of IV bag hooks coupled to an upper end of the second portion.

17. The equipment support of claim 14, further comprising a pair of handles extending forwardly from the lower cross bar adjacent to the outer posts.
