Abstract

An orthopedic traction device includes a frame having two side supports spaced from one another to provide an open area between them. Each of the side supports has a flat bottom wall and an arcuately shaped upper wall. Between the side supports, two rows of spaced protuberances are provided, with each row being arcuately disposed in a manner generally parallel to the arcuately shaped upper walls of the two side supports. Each row consists of a multiplicity of spaced generally rectangular protuberances with each rectangular protuberance being elongated in a direction perpendicular to the axis of elongation of the frame. Between adjacent protuberances, a scalloped portion is provided. The radius of curvature of each row of spaced protuberances varies from a relatively large radius of curvature adjacent one end of the rows to a smaller radius of curvature at the other end thereof.

Claims

1. An adjustable non-powered orthopedic traction device, comprising:

a) a frame having a longitudinal axis of elongation including two spaced side supports with an arcuate upper wall, the side supports defining an opening therebetween, each side support including a bottom wall adapted to engage a floor surface;

b) two parallel spaced arcuate rows disposed in said opening between said supports, each row including a multiplicity of protuberances spaced along said axis with a scalloped recess between each protuberance; and

c) a continuous opening between said rows together with a continuous opening between each side support and closest row.

2. The device of claim 1, wherein each of said arcuate rows has a curvature that continuously varies from a relatively large radius of curvature adjacent one end to a relatively small radius of curvature adjacent another end.

3. The device of claim 1, wherein each protuberance is generally rectangular.

4. The device of claim 3, wherein each generally rectangular protuberance is elongated in a direction perpendicular to said axis.

5. The device of claim 1, wherein said side supports and rows are parallel and attached by three spaced apart lateral cross supports.

6. An adjustable non-powered orthopedic traction device, comprising:

a) a frame having a longitudinal axis of elongation including two spaced parallel side supports defining an opening therebetween, each side support including a planar bottom wall adapted to engage a floor surface and an arcuate upper wall;

b) two spaced arcuate parallel rows disposed in said opening between said supports, each row including a multiplicity of rectangular protuberances spaced along said axis by respective scalloped recesses; and

c) a continuous opening between said rows together with a continuous opening between each side support and closest row.

7. The device of claim 6, wherein each of said arcuate rows has a curvature that continuously varies from a relatively large radius of curvature adjacent one end to a relatively small radius of curvature adjacent another end.

8. The device of claim 6, wherein each generally rectangular protuberance is elongated in a direction perpendicular to said axis.

9. An adjustable non-powered orthopedic traction device, comprising:

a) two spaced arcuate rows, each row including a multiplicity of generally rectangular protuberances spaced therealong with a scalloped recess between each respective pair of adjacent protuberances;

b) each row having a curvature that continuously varies from a relatively large radius of curvature adjacent one end to a relatively small radius of curvature adjacent another end;

c) each row spaced apart from an exterior frame side support having a longitudinal axis of elongation parallel to the two spaced arcuate rows; and

d) each row joined by lateral cross supports to the exterior frame side supports.

10. The device of claim 9, wherein said rows are parallel and extend along an axis of elongation, each generally rectangular protuberance being elongated in a direction perpendicular to said axis.
