Abstract
Abstract A power column is a hollow post having six vertical walls and is mounted between horizontal arms pivoted to the floor and ceiling, respectively. The pivotal axis for the arms passes through the head end of a hospital bed, enabling the power column to swing from one side of the bed to the other. The electrical outlets are on two walls separated by a front wall so that one or the other of the walls is easily accessible whether the power column is on either side of the bed. Lateral horizontal rails are pivotably mounted on either side of the column. The height of the rails is adjustable. The rails contain one or more gas outlets which are laterally adjustable on the rail and can carry other accessories that are laterally adjustable.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
165 words
A power column adapted to be accurately moved from one side of a hospital bed around its end to the other side of said bed, said power column comprising: a hollow, vertical housing having six vertical walls, means supporting said housing and permitting said housing to be arcuately moved from one side of the bed past one end of the bed to the other side of the bed, said vertical walls including a front wall having two vertical edges, an outlet wall extending from each vertical edge of said front wall at an angle of about 45° to the plane of said front wall, opposed side walls connected to said outlet walls, a back wall connected to said side walls, and a plurality of electrical outlets on said outlet walls, whereby, when said column is arcuately moved to either side of said bed, an outlet wall will be disposed substantially perpendicular to the side of the bed and thus optimally accessible to an attending nurse.
Claim 2
Dependent Claim
165 words
A power column adapted to be accurately moved from one side of a hospital bed around its end to the other side of said bed, said power column comprising: a hollow, vertical housing having six vertical walls, means supporting said housing and permitting said housing to be arcuately moved from one side of the bed past one end of the bed to the other side of the bed, said vertical walls including a front wall having two vertical edges, an outlet wall extending from each vertical edge of said front wall at an angle of about 45° to the plane of said front wall, opposed side walls connected to said outlet walls, a back wall connected to said side walls, and a plurality of electrical outlets on said outlet walls, whereby, when said column is arcuately moved to either side of said bed, an outlet wall will be disposed substantially perpendicular to the side of the bed and thus optimally accessible to an attending nurse.
Claim 3
Dependent Claim
62 words

Claim 4
Dependent Claim
24 words
A power column as in claim 2 further comprising: means for adjusting the height of said gas rail with respect to said power column.
Claim 5
Dependent Claim
28 words
A power column as in claim 1 further comprising: at least one vertical rail on each side wall, and at least one accessory mounted on said vertical rail.
Claim 6
Dependent Claim
56 words
A power column as in claim 1 further comprising: vertical interior walls forming with each outlet wall two vertical housings within said power column for each outlet wall, and means forming four vertical raceways between said vertical housing for the following categories of electrical connections; 110volt supply emergency power low voltage conductors low voltage communication systems.
Claim 7
Dependent Claim
40 words
A power column as in claim 5 further comprising a plurality of vertical gas supply tubes mounted between said vertical housings and said back wall, a plurality of hook-up outlets connected to said tubes and projecting through said back wall.
Claim 8
Dependent Claim
114 words
A hollow power column comprising: a plurality of vertical walls interconnected to form a power column, vertical rails on at least one wall of said power column, a plurality of horizontal gas rails, means pivotally and vertically slidably mounting said gas rails on said vertical rails, a plurality of vertical gas supply tubes in said power column, at least one gas outlet mounted on said gas rail, means connecting said outlet to one of said vertical gas supply tubes, and means supporting said power column and permitting said power column to be arcuately moved from one side of a hospital bed past one end of the bed to the other side of the bed.
Claim 9
Dependent Claim
114 words
A hollow power column comprising: a plurality of vertical walls interconnected to form a power column, vertical rails on at least one wall of said power column, a plurality of horizontal gas rails, means pivotally and vertically slidably mounting said gas rails on said vertical rails, a plurality of vertical gas supply tubes in said power column, at least one gas outlet mounted on said gas rail, means connecting said outlet to one of said vertical gas supply tubes, and means supporting said power column and permitting said power column to be arcuately moved from one side of a hospital bed past one end of the bed to the other side of the bed.
