US Patent 7345869 Supporting frame structure

A supporting frame structure movably joined in a case is used to mount a loaded object, such that the object can be disposed in the case or moved outside the case. In the present invention, a motion mechanism is disposed between the case and the supporting frame, by which the supporting frame has a handling position outside the case and a fixed position inside the case. At the fixed position, the motion mechanism forms an interference relation, such that the supporting frame is fixed on the mounting position and is unable to be departed from the case.
