ABSTRACT:
A second cylindrical element with a side wall oriented generally parallel to the first plane is telescopically interconnected with a first cylindrical element and includes an upper surface. The second cylindrical element is rotationally displaceable between, first, second and third angular positions within a second plane orthogonal to the first plane and is telescopically displaceable between compressed and expanded positions. A biasing device biases the first and second cylindrical elements into the expanded position. A locking device maintains the first and second cylindrical elements in the first angular position when the first and second cylindrical elements are placed in the expanded position. The locking device enables the biasing device to displace the first and second cylindrical elements into the second angular position when the first and second cylindrical elements are displaced from the expanded position into the compressed position. The locking device also enables the biasing device to displace the first and second cylindrical elements into the third angular position when the first and second cylindrical elements are displaced from the compressed position into the expanded position.
