Abstract

Abstract A support assembly for stationary support from a suitable structure and including a support arm pivotally supported therefrom for swinging in a vertical plane about a horizontal transverse axis. An elongated upright tension member is provided and one end portion of the arm defines an anchor point to which the upper end of the upright tension member is attached. The lower end portion of the tension member has a head sling supported therefrom and a weight is carried by the arm and adjustable therealong relative to the axis of oscillation of the arm for swinging the arm, by gravity weighting, in a direction causing the lower end portion of the tension member and the head sling supported therefrom to be urged upwardly, whereby an upward force may be exerted upon a person''s head engaged by the sling.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 234 words
A support assembly for stationary mounting from a suitable support structure, said support assembly including a base adapted for mounting on said support structure and including a horizontally outwardly projecting support arm, a lift arm including a first inner end pivotally supported from said base below the inner end of the support arm for rotation about a horizontal axis relative to the base and including an outer end spaced below the outer end of the support arm, tension member guide means carried by the outer end of the support arm, an elongated flexible tension member looped over the guide means and including two depending end portions, a first end portion of the tension member being anchored to the outer end of the lift arm and the second end portion of the tension member having a head sling supported therefrom, weight means supported from said lift arm intermediate said axis and the outer terminal end of said lift arm and adjustably positionable therealong, said base defining a downwardly opening channel extending transversely of said support arm for embracingly engaging the upper marginal edge portion of a door, said channel being defined between a pair of depending generally parallel flange portions supported for adjustable positioning toward and away from each other, said inner ends of said support and lift arms being supported from the outer surface of one of said flanges remote from the other flange.
Claim 2
Dependent Claim 234 words
A support assembly for stationary mounting from a suitable support structure, said support assembly including a base adapted for mounting on said support structure and including a horizontally outwardly projecting support arm, a lift arm including a first inner end pivotally supported from said base below the inner end of the support arm for rotation about a horizontal axis relative to the base and including an outer end spaced below the outer end of the support arm, tension member guide means carried by the outer end of the support arm, an elongated flexible tension member looped over the guide means and including two depending end portions, a first end portion of the tension member being anchored to the outer end of the lift arm and the second end portion of the tension member having a head sling supported therefrom, weight means supported from said lift arm intermediate said axis and the outer terminal end of said lift arm and adjustably positionable therealong, said base defining a downwardly opening channel extending transversely of said support arm for embracingly engaging the upper marginal edge portion of a door, said channel being defined between a pair of depending generally parallel flange portions supported for adjustable positioning toward and away from each other, said inner ends of said support and lift arms being supported from the outer surface of one of said flanges remote from the other flange.
Claim 3
Dependent Claim 20 words
The combination of claim 1 wherein the inner opposing surfaces of said flanges are covered with a resilient protective coating.
Claim 4
Dependent Claim 35 words
The combination of claim 1 wherein the upper marginal portion of said lift arm has a plurality of longitudinally spaced notches formed therein, said weight means including a suspension hook removably engageable in said notches.
Claim 5
Dependent Claim 77 words
The combination of claim 1 wherein said head sling includes an elongated flexible strap disposed in a vertical loop with its upper portion anchored to the end of said tension member remote from the free end of said lift arm, and an adjustable length brace secured between and frictionally engaged with the upper portions of the sides of said loop with said upper portions frictionally retained against longitudinal displacement relative to the opposite ends of said brace.
Claim 6
Dependent Claim 45 words
The combination of claim 4 wherein said sling includes a second flexible adjustable strap arranged in an upwardly opening and inclined loop, the upper ends of said second loop being secured to the sides of the first loop below the opposite ends of said brace.
Claim 7
Dependent Claim 148 words
A variable weight traction unit comprising an inverted U-shaped base adapted to embracingly engage the upper marginal edge portion of a horizontally swingable door, a support arm structure projecting horizontally ouTwardly from one side of said base, a generally horizontal lift arm disposed on said one side of said base and generally paralleling said support arm, one end of said lift arm being pivotally secured to said one side of said base for swinging about a horizontal axis extending transversely of said lift arm, a pulley assembly supported from the outer end of said support arm, an elongated flexible tension member passed over said pulley assembly and having a first end secured to the end of said lift arm remote from said base, the other end of said tension member having a head sling supported therefrom, and a weight supported from said lift arm and adjustably positionable therealong.
Claim 8
Dependent Claim 148 words
A variable weight traction unit comprising an inverted U-shaped base adapted to embracingly engage the upper marginal edge portion of a horizontally swingable door, a support arm structure projecting horizontally ouTwardly from one side of said base, a generally horizontal lift arm disposed on said one side of said base and generally paralleling said support arm, one end of said lift arm being pivotally secured to said one side of said base for swinging about a horizontal axis extending transversely of said lift arm, a pulley assembly supported from the outer end of said support arm, an elongated flexible tension member passed over said pulley assembly and having a first end secured to the end of said lift arm remote from said base, the other end of said tension member having a head sling supported therefrom, and a weight supported from said lift arm and adjustably positionable therealong.
