Abstract
Abstract There is provided apparatus which has an elongated, preferably telescopingly adjustable member having at one end thereof a latch engaging the vertically extending pole or standard of a free-wheeling IV mechanism, and a machanism on the opposite end thereof for attaching the same to a vehicle, preferably a wheelchair. In a preferred embodiment, the latch engaging the vertically extending pole or standard has a symmetrical pair of hingedly joined hemicylindrical pieces which are adapted to encircle the pole or standard, one of the pieces being fixedly attached to the elongated member, and there is on one of the two hemicylindrical pieces a locking pin and on the other one of the two hemicylindrical pieces a latch for engaging locking pin. With the aid of such apparatus, a person acting unaided may safely and conveniently transport a passenger-patient connected to IV equipment or apparatus, despite the need to traverse places where the flooring is uneven.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
Attachment apparatus for joining a patient carrying wheeled vehicle to an intravenous pole assigned having an upstanding elongated IV pole mounted upon a wheeled base, said attachment apparatus comprising an elongated arm including two tubes telescopically received one within the other; an elongated tubular housing formed by two arcuate segments connected by a hinge, one of said acruate segment being fixedly connected to an end of one of said tubes; latch means releasably connecting said two arcuate segments into said tubular housing; and stop means located within said tubes for limiting the extent of extension of said tubes, said tubes means including a positioning means anchored to one of said tubes and a flexible member having terminal end portions secured to the other one of said tubes.
Claim 2
Dependent Claim
127 words
Attachment apparatus for joining a patient carrying wheeled vehicle to an intravenous pole assigned having an upstanding elongated IV pole mounted upon a wheeled base, said attachment apparatus comprising an elongated arm including two tubes telescopically received one within the other; an elongated tubular housing formed by two arcuate segments connected by a hinge, one of said acruate segment being fixedly connected to an end of one of said tubes; latch means releasably connecting said two arcuate segments into said tubular housing; and stop means located within said tubes for limiting the extent of extension of said tubes, said tubes means including a positioning means anchored to one of said tubes and a flexible member having terminal end portions secured to the other one of said tubes.
Claim 3
Dependent Claim
53 words
The attachment apparatus according to claim 1 wherein said latch means includes post members at opposite end portions of the elongated length of said tubular housing, and latch plates pivotally supported by an arcuate segment of said housing opposite the arcuate segment having said post members for locking engagement with the post members.
Claim 4
Dependent Claim
18 words
The attachment apparatus according to claim 1 further including means for interlocking said tubes in their extending position.
Claim 5
Dependent Claim
29 words
The attachment apparatus according to claim 1 wherein said stop means includes a flexible metal band having terminal end portions secured by a fastener to one of said tubes.
Claim 6
Dependent Claim
40 words
The attachment apparatus according to claim 4 wherein said flexible band member is engageable with an anchor pin supported by the other of said tubes at a position determining the extended telescopic position of one tube relative to the other.
Claim 7
Dependent Claim
14 words
Apparatus as defined in claim 5, wherein said friction means includes hemicylindrical resilient member.
Claim 8
Dependent Claim
71 words
The apparatus according to claim 1, wherein said elongated tubular housing extends along a length of the pole for guided longitudinal movement by the pole and wherein said apparatus further includes means supported by one of the said hemicylindrical pieces for squashing against said pole to thereby press the opposite side of said pole against a hemicylindrical piece to restrain said pole against rotary movement with respect to said hemicylindrical pieces.
