Containerized frame and means for its telescopic projection and retraction

A multi-use frame structure and means for its projection-retraction from a container comprising:

• a container;
• a frame structure;
• a rotatable motion conversion means active at least at some point during both the projection and retraction processes of said frame structure in relation to said container;
• said motion conversion means further comprising actuation shaft means having helical torque transfer means;
• a first rotatable member concentrically positioned with respect to said actuation shaft means and rotatable relative thereto having an interior configuration coactive with the exterior helical torque transfer means of said actuation shaft means and having an exterior helical torque transfer means including a configuration opposite to that of said actuation shaft means;
• at least a second rotatable member concentrically positioned with respect to said first rotatable member having an interior configuration coactive with the exterior helical torque transfer means of said first rotatable member;
• means to prevent the rotation of said at least one other rotatable member;
• and,
• drive means.
