Abstract
Abstract An electrically safe hospital bed comprises a pair of independently operable mechanical jacks which include electrically non-conductive, pivotally interconnected links and which are spaced apart to define an unobstructed region therebetween to permit access by X-ray equipment. An electrically non-conductive, X-ray transparent mattress support platform is mounted on these jacks.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
Hospital bed apparatus comprising: first and second independently operable scissors jack means each including a system of pivotally interconnected links arranged transversely of said platform means with a selectively operable screw threadedly connected to said links adjacent one pivotal interconnection thereof and journalled adjacent an oppositely positioned pivotal interconnection of said links, said first jack means being spaced laterally apart from said second jack means to provide separate, raisable and lowerable support for the respective ends of mattress support platform means; mattress support platform means mounted overlyingly on said first and second jack means; first drive means for said first jack means including a first independently energizable motor; and second drive means for said second jack means including a second motor, said second motor being energizable independently of said first motor whereby said motors may be operated for selectively raising and lowering the respective ends of said platform means in unison or independently.
Claim 2
Dependent Claim
153 words
Hospital bed apparatus comprising: first and second independently operable scissors jack means each including a system of pivotally interconnected links arranged transversely of said platform means with a selectively operable screw threadedly connected to said links adjacent one pivotal interconnection thereof and journalled adjacent an oppositely positioned pivotal interconnection of said links, said first jack means being spaced laterally apart from said second jack means to provide separate, raisable and lowerable support for the respective ends of mattress support platform means; mattress support platform means mounted overlyingly on said first and second jack means; first drive means for said first jack means including a first independently energizable motor; and second drive means for said second jack means including a second motor, said second motor being energizable independently of said first motor whereby said motors may be operated for selectively raising and lowering the respective ends of said platform means in unison or independently.
