I V Pole interconnection coupling

Claim 2

Claim 3

The combination according to claim 1 wherein said first and second members are tubular members, at least one of which is hollow with the other of said members inserted into such hollow member for effecting said relative rotational positions of said members.

Claim 4

The combination according to claim 2 wherein said first tubular member is hollow.

Claim 5

A coupling for interconnecting a wheel intravenous feeding bottle support stand with a wheeled patient-carrying apparatus including in combination: a first hollow tubular member for rigid attachment to a wheeled patient-carrying apparatus, said first tubular member having an axial slot formed through the wall of said first member for a portion of the length thereof, with at least one offset circumferential slot joining said axial slot; and a second tubular member having clamp means attached to one end thereof, said clamp means being adapted for removable attachment to the pole of a wheeled intravenous feeding bottle support stand, said second tubular member being inserted into said first tubular member and said second tubular member having a radially extending slot engagement pin thereon for extending into the slot in said first tubular member when said second tubular member is inserted into said first tubular member; wherein said pin on said second tubular member engages said slot in said first tubular member for controlling and limiting the axial and rotational movement of said second tubular member within said first tubular member to define a first stored position of said second member adjacent the patient-carrying apparatus and for defining a second use position of said second tubular member spaced at least in part away from said patient-carrying apparatus for connection of said clamp means with the pole of such wheeled intravenous feeding bottle support stand so that such stand is coupled for movement with such wheeled patient-carrying apparatus.

Claim 6

A coupling for interconnecting a wheel intravenous feeding bottle support stand with a wheeled patient-carrying apparatus including in combination: a first hollow tubular member for rigid attachment to a wheeled patient-carrying apparatus, said first tubular member having an axial slot formed through the wall of said first member for a portion of the length thereof, with at least one offset circumferential slot joining said axial slot; and a second tubular member having clamp means attached to one end thereof, said clamp means being adapted for removable attachment to the pole of a wheeled intravenous feeding bottle support stand, said second tubular member being inserted into said first tubular member and said second tubular member having a radially extending slot engagement pin thereon for extending into the slot in said first tubular member when said second tubular member is inserted into said first tubular member; wherein said pin on said second tubular member engages said slot in said first tubular member for controlling and limiting the axial and rotational movement of said second tubular member within said first tubular member to define a first stored position of said second member adjacent the patient-carrying apparatus and for defining a second use position of said second tubular member spaced at least in part away from said patient-carrying apparatus for connection of said clamp means with the pole of such wheeled intravenous feeding bottle support stand so that such stand is coupled for movement with such wheeled patient-carrying apparatus.

Claim 7

The combination according to claim 4 wherein said second tubular member is adapted for telescoping movement within said first tubular member defined by the limits by said axial slot.

Claim 8

The combination according to claim 5 wherein said clamp means attached to said one end of said second tubular member comprises a clamp member carried on an extension rod attached to said one end of said second tubular member at a 90° angle thereto.

Claim 9

The combination according to claim 6 wherein the wheeled patient-carrying apparatus is a wheelchair and said axial slot through the wall of said first tubular member is intermediate the ends thereof and is in a substantially horizontal plane with said first tubular member attached to the wheelchair, with a first circumferential slot extending downwardly from said axial slot at the extreme end thereof located toward the front of the wheelchair when said first tubular member is attached thereto and including at least a second circumferential slot opening into said axial slot and extending substantially 90° from said axial slot over the top of said first tubular member when said first member is attached to said wheelchair, said first circumferential slot defining said stored position of said members and said second circumferential slot defining said use position of said members.

Claim 10

A coupling for interconnecting a wheel intravenous feeding bottle support stand with a wheeled bed including in combination: a first hollow tubular member for rigid attachment in a vertical orientation to said wheeled bed, said first hollow tubular member having a circumferential slot extending at least 90° along the circumference of said first hollow tubular member; a second tubular member inserted into said first tubular member for relative telescoping movement therewith and for axial rotation relative to said first tubular member, said second tubular member having a radially extending slot engagement pin thereon for extending into said slot in said first tubular member when said second tubular member is inserted into said first tubular member; wherein said pin and said slot limit the relative rotational movement of said first and second tubular members for holding said second member in a first stored position relative to said first member and for holding said second member in a second use position for connection of said clamp means with the pole of such wheeled intravenous feeding bottle support stand so that such stand is coupled for movement with such wheeled bed, said stored and said use positions comprising different relative rotational positions of said first and second tubular members with respect to one another.

Claim 11

A coupling for interconnecting a wheel intravenous feeding bottle support stand with a wheeled bed including in combination: a first hollow tubular member for rigid attachment in a vertical orientation to said wheeled bed, said first hollow tubular member having a circumferential slot extending at least 90° along the circumference of said first hollow tubular member; a second tubular member inserted into said first tubular member for relative telescoping movement therewith and for axial rotation relative to said first tubular member, said second tubular member having a radially extending slot engagement pin thereon for extending into said slot in said first tubular member when said second tubular member is inserted into said first tubular member; wherein said pin and said slot limit the relative rotational movement of said first and second tubular members for holding said second member in a first stored position relative to said first member and for holding said second member in a second use position for connection of said clamp means with the pole of such wheeled intravenous feeding bottle support stand so that such stand is coupled for movement with such wheeled bed, said stored and said use positions comprising different relative rotational positions of said first and second tubular members with respect to one another.

Claim 12

The combination according to claim 8 wherein said clamp means attached to said one end of said second tubular member comprises a clamp member carried on an extension rod attached to said one end of said second tubular member at a 90° angle thereto.
