Abstract
Abstract An orthopedic traction frame for an adjustable hospital bed having relatively movable head and foot portions to adjustably position the mattress of the bed, the frame comprising of a pair of upright elongate support members for attachment to the headboard and footboard portions of the bed respectively, and a horizontal elongate support member interconnecting the upper ends of the same. The lower end of the upright member at the foot of the bed is pivotally attached to the footboard of the bed for movement about an axis perpendicular to the longitudinal axis of the bed, and adjustable clamping device is provided for attaching the upper end of the upright member at the foot of the bed to the end of the horizontal support member for pivotal movement of the upper end about an axis perpendicular to the longitudinal axis of the bed, whereby the foot of the bed may be retractably positioned and the traction frame adjusted for optimum load support at all positions of adjustment of the bed and mattress.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
276 words
In an orthopedic traction frame for an adjustable hospital bed having relatively movable head and foot portions, said frame including a pair of elongate upright support members for attachment to the head and foot portions of the bed, respectively, a generally horizontal support member attached to and interconnecting the upper ends of the upright members for supporting orthopedic equipment thereon, and means for attaching the opposite ends of the upright member at the foot of the bed to the foot of the bed and to the horizontal support member, respectively, for pivotal movement of the ends about respective axes extending perpendicular to the length of the bed to permit variable positioning of the head and foot of the bed toward and away from each other; the improvement wherein said attaching means includes adjustable clamp means for pivotal attachment of the upper end of the upright member at the foot of the bed to the horizontal member, said clamp means including a releasable clamping portion for surroundingly engaging the horizontal member to permit its adjustable positioning along the length of the horizontal member, a base portion for fixed attachment to the upper end of the upright member at the foot of the bed, and means pivotally interconnecting the clamp portion and the base portion for relative movement of the same about an axis perpendicular to the length of the bed to permit relative movement of the head and foot portions of the bed and adjustable positioning of the clamp means along the length of the horizontal member to optimize strength and load support by the frame in various positions of the head and foot of the bed.
Claim 2
Dependent Claim
276 words
In an orthopedic traction frame for an adjustable hospital bed having relatively movable head and foot portions, said frame including a pair of elongate upright support members for attachment to the head and foot portions of the bed, respectively, a generally horizontal support member attached to and interconnecting the upper ends of the upright members for supporting orthopedic equipment thereon, and means for attaching the opposite ends of the upright member at the foot of the bed to the foot of the bed and to the horizontal support member, respectively, for pivotal movement of the ends about respective axes extending perpendicular to the length of the bed to permit variable positioning of the head and foot of the bed toward and away from each other; the improvement wherein said attaching means includes adjustable clamp means for pivotal attachment of the upper end of the upright member at the foot of the bed to the horizontal member, said clamp means including a releasable clamping portion for surroundingly engaging the horizontal member to permit its adjustable positioning along the length of the horizontal member, a base portion for fixed attachment to the upper end of the upright member at the foot of the bed, and means pivotally interconnecting the clamp portion and the base portion for relative movement of the same about an axis perpendicular to the length of the bed to permit relative movement of the head and foot portions of the bed and adjustable positioning of the clamp means along the length of the horizontal member to optimize strength and load support by the frame in various positions of the head and foot of the bed.
Claim 3
Dependent Claim
31 words
A frame as defined in claim 1 wherein the horizontal member comprises an elongate bar having a generally unobstructed exterior surface for securement of said clamp means at various positions therealong.
Claim 4
Dependent Claim
55 words
A frame as defined in claim 1 wherein said clamping portion of the clamp means comprises a pair of generally semi-circular clamping jaws pivotally connected at one end to each other, and adjustable fastening means for securing the other ends of the jaws together about the periphery of the horizontal support member of the frame.
Claim 5
Dependent Claim
50 words
A frame as defined in claim 1 wherein said base portion of the clamp means includes a stub member receivable in an open end of the upright member at the foot of the bed for fixed positional attachment of the clamp means to the upper end of the upright member.
