Abstract
Abstract An elongated base mounting an aligned elevator and traction panel. The elevator is hinged to the base and operating components are mounted on the base for selectively vertically pivoting the elevator. The traction panel is mounted for longitudinal movement on the base and the base incorporates operating components for effecting the longitudinal movement of the traction panel. The elevator and traction panel mount patient engaging harnesses in a manner whereby longitudinal movement of the traction panel applies traction to the patient.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
216 words
Traction apparatus comprising an elongated planar base panel, said base panel having a foot end and a head end, a one-piece traction panel overlying said base panel in closely spaced generally parallel relation thereto for a major portion of the length thereof from the foot end, a one-piece elevator panel overlying the base panel in closely spaced generally parallel relation thereto from the head end to approximately the traction panel, traction means mounted on the base panel and engaged between the base panel and the traction panel for effecting a longitudinal movement of the traction panel relative to the elevator panel, and elevating means mounted on the base panel and engaged between said base panel and said elevator panel for effecting a vertical adjustment of said elevator panel, said elevator panel being pivotally mounted to said base panel approximately at the edge thereof adjoining said traction panel and being vertically pivotable about the point of pivotal mounting, the adjoining edges of the elevator panel and traction panel comprising a series of internesting tongues and notches transversely across these panels on the respective edge portions whereby an area of continuous overlap is provided between the traction panel and elevator panel throughout the range of longitudinal adjustment of the traction panel for a continued support of a patient.
Claim 2
Dependent Claim
216 words
Traction apparatus comprising an elongated planar base panel, said base panel having a foot end and a head end, a one-piece traction panel overlying said base panel in closely spaced generally parallel relation thereto for a major portion of the length thereof from the foot end, a one-piece elevator panel overlying the base panel in closely spaced generally parallel relation thereto from the head end to approximately the traction panel, traction means mounted on the base panel and engaged between the base panel and the traction panel for effecting a longitudinal movement of the traction panel relative to the elevator panel, and elevating means mounted on the base panel and engaged between said base panel and said elevator panel for effecting a vertical adjustment of said elevator panel, said elevator panel being pivotally mounted to said base panel approximately at the edge thereof adjoining said traction panel and being vertically pivotable about the point of pivotal mounting, the adjoining edges of the elevator panel and traction panel comprising a series of internesting tongues and notches transversely across these panels on the respective edge portions whereby an area of continuous overlap is provided between the traction panel and elevator panel throughout the range of longitudinal adjustment of the traction panel for a continued support of a patient.
Claim 3
Dependent Claim
170 words
The apparatus of claim 1 wherein said traction means comprises an elongated shaft, said shaft being bracket mounted longitudinally on said base panel, said shaft being rotatable within the bracket mounts and orientated above said base panel and below said traction panel, said shaft including a threaded portion, bracket means depending from said traction panel, said shaft being threaded within said bracket means whereby rotation of said shaft causes a longitudinal movement of the bracket means and traction panel secured thereto, and means for rotating said shaft, said means for rotating the shaft comprising a second shaft extending laterally from said first shaft, said second shaft being rotatably mounted on said base panel, bevel gears on adjoining portions of the first and second mentioned shafts whereby a rotation of the second shaft will effect a corresponding rotation of the traction panel moving shaft and a handle on the remote end of the second shaft laterally of one side of the traction panel for effecting a rotation of the second shaft.
Claim 4
Dependent Claim
43 words
The apparatus of claim 2 including a one-piece mattress overlying and configured to conform to said traction panel, and a second one-piece mattress overlying and configured to conform to said elevator panel, said mattresses having adjoining edges incorporating internesting tongues and notches therealong.
Claim 5
Dependent Claim
43 words
The apparatus of claim 1 including a one-piece mattress overlying and configured to conform to said traction panel, and a second one-piece mattress overlying and configured to conform to said elevator panel, said mattresses having adjoining edges incorporating internesting tongues and notches therealong.
Claim 6
Dependent Claim
165 words
Traction apparatus comprising an elongated base, said base having a foot end and a head end, a traction panel overlying said base for a major portion of the length from the foot end, an elevator overlying the base from the head end to approximately the traction panel, said elevator being pivotally secured to said base panel approximately at the edge thereof adjoining said traction panel, traction means engaged between the base and the traction panel for effecting a longitUdinal movement of the traction panel relative to the elevator, and elevating means engaged between said base and said elevator for effecting a vertical pivoting of said elevator, the adjoining edges of said elevator and traction panel comprising a series of internesting tongues and notches longitudinally therealong on the respective edge portions whereby an area of continuous overlap is provided between the traction panel and the elevator throughout the range of adjustment of the traction panel relative to the elevator for a continued support of a patient.
Claim 7
Dependent Claim
165 words
Traction apparatus comprising an elongated base, said base having a foot end and a head end, a traction panel overlying said base for a major portion of the length from the foot end, an elevator overlying the base from the head end to approximately the traction panel, said elevator being pivotally secured to said base panel approximately at the edge thereof adjoining said traction panel, traction means engaged between the base and the traction panel for effecting a longitUdinal movement of the traction panel relative to the elevator, and elevating means engaged between said base and said elevator for effecting a vertical pivoting of said elevator, the adjoining edges of said elevator and traction panel comprising a series of internesting tongues and notches longitudinally therealong on the respective edge portions whereby an area of continuous overlap is provided between the traction panel and the elevator throughout the range of adjustment of the traction panel relative to the elevator for a continued support of a patient.
