ABSTRACT:
The invention provides a support stand for a workpiece which is stable, height adjustable and easily storable when not in use. The stand includes a platform section having a flat platform member and a tubular member mounted under the platform member. A first inner cylindrical leg having holes disposed at intervals along the length thereof is mounted under the platform member. A first outer cylindrical leg is slidably mounted over the first inner cylindrical leg having a hole located at the top for communication with any of the first holes of the inner leg. A T-shaped member comprising a second outer cylindrical leg is slidably mounted over the second inner cylindrical leg and has third holes disposed at intervals along its length and fifth holes located at the top 90.degree. from the third holes. Pin means are employed for locking the first inner leg to the first outer leg and the second inner leg to the first outer leg and the second inner leg to the second outer leg. The horizontal section of the T-shaped member can be rotated to a position coplanar with the platform section and locked in the position by the pin means. A cylindrical sleeve having a clamp is also mounted on the platform section. A tubular upright section is slidably fitted in the sleeve, the tubular upright section being storable within the tubular member. The apparatus further includes an accessory for the upright section which includes a cylindrical support member releasably mounted in the upright member, a clamp mounted on the support member at one and and end a hook mounted on the support member at the other end.
