ABSTRACT:
A telescoping IV pole has a bottom pole with a support at a bottom end thereof for facilitating an orienting of said bottom pole in an upright, vertically oriented position. A top pole is provided which is slidably disposed within the bottom pole in a telescoping manner. The top pole has at a top end thereof an intravenous fluid container support and at a bottom end thereof a circumferential locking groove. A pole latch is provided for automatically effecting an interlock with the locking groove when the top pole is deployed to an extended position outside of the bottom pole. The pole latch includes plural latch members each being supported for movement into and out of the locking groove. A spring is provided for urging the latch members into the locking groove. A manually operable unlocking device is provided for effecting a simultaneous release of the interlock so that the top pole will telescope into the bottom pole. A control device is provided for effecting simultaneous rotational and axial translational movement of the manually operable unlocking device relative to the top and bottom poles so as to effect a simultaneous forceful urging of the latch members of the locking groove against the urging of the spring.
