Abstract
Electromechanically actuated bifolding closure apparatus including a vertical support post; a pair of generally C-shaped frame members disposed in facing relationship and pivotally joined together at their distal extremities such that in a closed disposition the two C-shaped members lie in a single plane and form a rectangularly configured super-structure, and in an opened disposition lie in different, spaced apart parallel planes rotated either 90 degrees relative to or parallel to the closed plane; hinge apparatus pivotally connecting one of said C-shaped units to the vertical post; a motive power source carried by one of the C-shaped members at a position proximate the support post; a gear drive mechanism associated with the hinging apparatus at the post and at the pivotal connection of at least one set of the distal ends of the C-shaped members; and a mechanical drive linkage coupling the motive power source to each of the gear mechanisms, such that when the motor caused the associated drive linkage to be rotated in one direction, the structure is rotated from a closed position to an open position, and when the motor causes the drive linkage to be rotated in the other direction, the structure is rotated from the open position to the closed position.
