Claim 15:
16. In a rooftop package delivery receptacle for unmanned aerial vehicles suitable for installation within a fixed curb frame comprising longitudinal frame members and transverse frame members defining a roof aperture, the combination of
a. a pair of hinge joints mounted directly upon the longitudinal frame members of the frame, the hinge joints being adapted to pivotably receive portions of an expandable contractible platform therewithin;
b. electromechanical rotational means configured for enabling the platform to rotate between a normally closed position substantially parallel to the frame, midway to a substantially horizontal position for package delivery, and upward to an inwardly slanted position for package collection and to any position therebetween;
c. the expandable contractible platform including a plurality of coplanar slidably mounted panels;
d. sliding means configured for enabling the panels to longitudinally and transversely expand outwards and contract inwards;
e. electromechanical expansion and contraction means configured for expanding the platform outwards for package delivery and contracting the platform inwards the package collection and platform closure; and
f. an upper and lower accordion shaped shutter portion removably attached between the frame and the platform adapted to enclose gaps therebetween.
