Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
185 words
An undercarriage for a bed comprising: a base comprising a plurality of longitudinally extending, substantially parallel beams and a transverse beam rigidly mounted to said longitudinally extending beams, said transverse beam holding said longitudinally extending beams in transversely spaced relationship; a bed support comprising a first longitudinally extending beam, a second longitudinally extending beam substantially parallel to said first longitudinally extending beam and spaced longitudinally therefrom, and a third longitudinally extending beam substantially parallel to and connected to said first and second longitudinally extending beams, said third longitudinally extending beam being connected to said first and second longitudinally extending beams on the side away from said base; means for lowering said first, second and third longitudinally extending beams into a position in which said first and second longitudinally extending beams enter the space between the longitudinally extending beans of said base, the lowering of said first, second and third longitudinally extending beams being limited by engagement of the transverse beam of said base by said third set of longitudinally extending beams; and a patient support platform mounted to said first and second longitudinally extending beams.
Claim 2
Dependent Claim
185 words
An undercarriage for a bed comprising: a base comprising a plurality of longitudinally extending, substantially parallel beams and a transverse beam rigidly mounted to said longitudinally extending beams, said transverse beam holding said longitudinally extending beams in transversely spaced relationship; a bed support comprising a first longitudinally extending beam, a second longitudinally extending beam substantially parallel to said first longitudinally extending beam and spaced longitudinally therefrom, and a third longitudinally extending beam substantially parallel to and connected to said first and second longitudinally extending beams, said third longitudinally extending beam being connected to said first and second longitudinally extending beams on the side away from said base; means for lowering said first, second and third longitudinally extending beams into a position in which said first and second longitudinally extending beams enter the space between the longitudinally extending beans of said base, the lowering of said first, second and third longitudinally extending beams being limited by engagement of the transverse beam of said base by said third set of longitudinally extending beams; and a patient support platform mounted to said first and second longitudinally extending beams.
Claim 3
Dependent Claim
14 words
The undercarriage of claim 1 wherein said lowering means comprises two independently operable mechanisms.
Claim 4
Dependent Claim
40 words
The undercarriage of claim 2 wherein one of said lifting mechanisms is pivotally mounted to said first set of longitudinally extending beams and the other of said lifting mechanisms is pivotally mounted to said second set of longitudinally extending beams.
Claim 5
Dependent Claim
22 words
The undercarriage of claim 1 wherein each of said mechanisms comprises a power screw, a motor and a plurality of lever means.
Claim 6
Dependent Claim
21 words
The undercarriage of claim 1 wherein said bed support platform is pivotally mounted to said first and second longitudinally extending beams.
