Abstract
Abstract A mobile hospital bed has a recess and has an IV pole supported for movement from an upright position to a storage position in which a hook on the pole is disposed in the recess in order to prevent the hook from snagging clothing or other nearby objects when the IV pole is not being used. The IV pole has three telescoping sections, and two locking mechanisms which respectively releasably secure the lower and middle pole sections and the middle and upper pole sections against relative movement, each locking mechanism being controlled by a manually rotatably actuator. An arrangement separate from the locking mechanisms is provided to prevent relative rotation of the lower and middle pole sections.

Claim 7
Dependent Claim
44 words
An apparatus of claim 5, wherein said means for preventing relative rotation includes said first pole section having an axially extending groove in an inner surface thereof and said second pole section having a radially projecting portion which is slidably received in said groove.
Claim 8
Dependent Claim
74 words
An apparatus of claim 6, wherein said first pole section has a further groove in said inner surface thereof which is diametrically opposed to said first-mentioned groove, and wherein said second section has extending radially therethrough a pin having first and second ends, said first end of said pin being said radially projecting portion slidably disposed in said first-mentioned groove, and said second end of said pin being slidably disposed in said further groove.
Claim 9
Independent Claim
218 words
An apparatus comprising: patient support means having at a first location thereon an upwardly facing surface and a recess opening downwardly into said patient support means through said upwardly facing surface, and an elongated pole having first and second ends and supported at said first end at a second location on said patient support means spaced from said first location for movement between an operational position and a storage position, said pole having at said second end thereof a hook, wherein said hook is disposed in said recess and said second end of said pole rests on said upwardly facing surface when said pole is in said storage position; and wherein said hook is movably supported on said pole and automatically moves into said recess as said pole moves from said operational to said storage position, wherein said pole extends approximately horizontally in said storage position, wherein said hook is freely rotatably supported on said pole for movement about a pivot axis which is approximately parallel to a central axis of said pole, and wherein as said pole is moved from said operational position to said storage position said hook is automatically pivoted about said pivot axis by gravity to a hanging position in which it is aligned with said downwardly opening recess in said patient support means.
