Patent ID: 7345869

Claim:
A supporting frame structure disposed in a case, comprising: a box for mounting a loaded object, and movably disposed in the case by a linear relation along a moving direction; and a motion mechanism connected to the case and the box, the motion mechanism including: a first actuator with one end pivotally connected to the box; a second actuator with one end pivotally connected to the other end of the first actuator, and the other end pivotally connected to the case; a third actuator with one end pivotally connected to the second actuator near the pivot between the first actuator and the second actuator; and an active component, movably disposed in the box by a linear relation, with one end pivotally connected to the other end of the third actuator; wherein a force is applied to the motion mechanism to make the box have a handling position outside the case and a fixed position inside the case.
