Abstract:
1. A power assist device for use in a luggage bin with a drop-down shell, in particular in a passenger aircraft, comprising: a load measuring mechanism to determine the load acting on the drop-down shell of the luggage bin; a power assist mechanism to apply an assist force to the shell counteracting the load with the power assist mechanism having a mechanical spring whose end areas can move toward one another against the return force of the spring from a first position in an actuation direction into a second position, with a first end area of the spring can be supported by a first abutment point on a base section and a second end area of the spring can be supported by a second abutment point against a support element that can be connected to the housing; an actuation mechanism set up to bring the power assist mechanism in an inactive operating state in which moving the spring from the second position into the first position is blocked and in an active operating state in which the spring can be moved from the second position into the first position; and the load measuring mechanism has a control connection with the actuation mechanism such that the actuation mechanism is moved from the inactive operating state to the active operating state when the load determined by the load measuring mechanism exceeds a specified threshold larger than the assist force wherein the actuation mechanism has at least two cooperating locking elements of which a first locking element is connected to the first abutment point and a second locking element is connected to the second abutment point and wherein the first locking element and the second locking element can be moved relative to one another perpendicular to the actuation direction between an activation position and a locked position such that, in the inactive operating state, the one locking element meshes with a form fit in the cooperating other locking element and wherein, in the active operating state, the one locking element releases the other locking element.
