Abstract

A pulley wheel support frame having a ring-shaped support rim having a top surface adapted to support a horizontal pulley wheel, said ring-shaped support rim being coupled, on a bottom side, to an opening adapted to receive a ram or a saddle of a jack; a base; and three or more height-adjustable support columns coupling the base to the ring-shaped support rim, said height-adjustable support columns each being fixable at a plurality of different heights.

First claim

What is claimed is:

1. A pulley wheel support frame, comprising:
a ring-shaped support rim having a top surface adapted to support a horizontal pulley wheel, said ring-shaped support rim being coupled, on a bottom side, to an opening adapted to receive a ram or a saddle of a jack;
a base; and
three or more height-adjustable support columns coupling the base to the ring-shaped support rim, said height-adjustable support columns each being fixable at a plurality of different heights.

2. The pulley wheel support frame of claim 1 , wherein a total height from a bottom of the base to the top surface of the ring-shaped support rim is below 1.5 feet in a default configuration of the three or more height-adjustable support columns.

3. The pulley wheel support frame of claim 1 , wherein the three or more height-adjustable support columns are fixable to a raised configuration with a total height from a bottom of the base to the top surface of the ring-shaped support rim at or above 1.5 feet.

4. The pulley wheel support frame of claim 1 , wherein the opening is embodied in a central housing that is coupled to the ring-shaped support rim by a plurality of frame legs.

5. The pulley wheel support frame of claim 4 , wherein the plurality of frame legs and the three or more height-adjustable support columns are attached to the ring-shaped support rim on the bottom side in an alternating circular arrangement.

6. The pulley wheel support frame of claim 1 , wherein the three or more height-adjustable support columns each comprise:
a guiding pipe extending from a bottom portion of the ring-shaped support rim;
a guide bar extending from a top portion of the base adapted for insertion into an internal channel at a bottom portion of the guiding pipe; and
a stud coupled to the guide bar that abuts the bottom portion of the guiding pipe.

7. The pulley wheel support frame of claim 6 , wherein the ring-shaped support rim is detachable from the base by withdrawing the guide bar from the internal channel of the guiding pipe in each of the three or more height-adjustable support columns.

8. The pulley wheel support frame of claim 6 , wherein the stud is fixable to a plurality of different locations on the guide bar corresponding to the plurality of different heights.

9. The pulley wheel support frame of claim 8 , wherein the stud and the guide bar are coupled to each other by complementary threads.
