Gravity traction apparatus

Claim 2

A gravity traction apparatus for human users, comprising: a vertically-extending frame with front and rear sides for mounting on a floor or like surface and including a horizontally disposed, transversely-extending beam member supported adjacent the upper end thereof; a thigh-pad structure with a generally flat, thigh-engaging surface having front and rear portions, supported on said beam member for pivotal movement between an inoperative position in which said surface is generally vertically disposed and an operative position in which said surface is generally horizontally disposed; and a knee-stop member and supporting means therefor carried by the thigh-pad structure, said knee-stop member including a transversely-extending leg-engaging portion which is spaced downwardly and rearwardly relative to the rear portion of said thigh-engaging surface when the thigh-pad structure is in the inoperative position, said supporting means being at a fixed distance relative to the rear portion of said thigh-pad structure, the amount of the spacing of the knee-stop member from said supporting means causing the leg-engaging portion to engage the legs of a user in the areas in back of the knees when the user is standing on the surface on which the frame is mounted and between said knee-stop member and said thigh-engaging surface, in which the frame includes spaced-apart front legs and stop means for limiting the pivotal movement of the thigh-pad structure between the inoperative position and the operative position, which stop means includes a tie-bar connected to and extending between the front ends adjacent to the beam member.

Claim 3

A gravity traction apparatus for human users, comprising: a vertically-extending frame with front and rear sides for mounting on a floor or like surface and including a horizontally disposed, transversely-extending beam member supported adjacent the upper end thereof; a thigh-pad structure with a generally flat, thigh engaging surface having front and rear portions, supported on said beam member for pivotal movement between an inoperative position in which said surface is generally vertically disposed and an operative position in which said surface is generally horizontally disposed; and a knee-stop member and supporting means therefor carried by the thigh-pad structure, said knee-stop member including a transversely-extending leg-engaging portion which is spaced downwardly and rearwardly relative to the rear portion of said thigh-engaging surface when the thigh-pad structure is in the inoperative position, said supporting means being at a fixed distance relative to the rear portion of said thigh-pad structure, the amount of the spacing of the knee-stop member from said supporting means causing the leg-engaging portion to engage the legs of a user in the areas in back of the knees when the user is standing on the surface on which the frame is mouonted and between said knee-stop member and said thigh-engaging surface, in which said vertically-extending frame includes complementary sets of front and rear legs having upper ends; bearing plates mounted at each end of the beam member and including two angularly-disposed tabs; means rigidly connecting the upper ends of one of the sets of front and rear legs to one of said tabs; means pivotally connecting the upper ends of the other set of front and rear legs to the other of said tabs; and at least one elongated spreader member extending between the sets of front and rear legs to vary the pivotal relationship therebetween.

Claim 4

A gravity traction apparatus for human users, comprising: a vertically-extending frame with front and rear sides for mounting on a floor or like surface and including a horizontally disposed, transversely-extending beam member supported adjacent the upper end thereof; a thigh-pad structure with a generally flat, thigh engaging surface having front and rear portions, supported on said beam member for pivotal movement between an inoperative position in which said surface is generally vertically disposed and an operative position in which said surface is generally horizontally disposed; and a knee-stop member and supporting means therefor carried by the thigh-pad structure, said knee-stop member including a transversely-extending leg-engaging portion which is spaced downwardly and rearwardly relative to the rear portion of said thigh-engaging surface when the thigh-pad structure is in the inoperative position, said supporting means being at a fixed distance relative to the rear portion of said thigh-pad structure, the amount of the spacing of the knee-stop member from said supporting means causing the leg-engaging portion to engage the legs of a user in the areas in back of the knees when the user is standing on the surface on which the frame is mouonted and between said knee-stop member and said thigh-engaging surface, in which said vertically-extending frame includes complementary sets of front and rear legs having upper ends; bearing plates mounted at each end of the beam member and including two angularly-disposed tabs; means rigidly connecting the upper ends of one of the sets of front and rear legs to one of said tabs; means pivotally connecting the upper ends of the other set of front and rear legs to the other of said tabs; and at least one elongated spreader member extending between the sets of front and rear legs to vary the pivotal relationship therebetween.

Claim 5

A gravity traction apparatus as described in claim 2, in which the upper ends of the front legs are rigidly connected to said one tab of each bearing plate, and a tie-bar is connected to and extends transversely between the front legs adjacent the upper ends thereof.
