A folding closure incorporating the female post is also described.
A locking post for a closure, the post having front and rear walls joined at their sides by two side walls to form a tubular post having a generally quadratic cross-sectional shape. Each side wall has a groove therein, the groove parallel to the longitudinal axis of the post, and wide enough and deep enough to at least partly receive a locking element carried by the post. The sides of the groove also provide handles which can be gripped to move a closure the post is mounted on.
A locking post for a folding door having two face panels and two end panels, the panels extending the length of the post. A plurality of relatively short, spacers are in the post, including a spacer at each end of the post. First fasteners fasten one face panel to each spacer on one side of each spacer and fasten the other face panel to each spacer on the side of each spacer opposite the one side, the face panels parallel and aligned. Second fastens detachably fasten one end panel to both face panels along one side of the face panels and detachably fasten the other end panel to both face panels on the other side of the face panels, the end panels parallel, the face panels and end panels together providing a tubular enclosure for the spacers.

A trolley for use with a folding door to suspend the door from an overhead track. The trolley has a mounting post for use in connecting the trolley to a folding door with a cylindrical mounting axle extending from the post. The trolley has a wheel unit comprising a short wheel axle with a wheel rotatably mounted at each end. The wheel unit is mounted on the post with the mounting axle on the post extending through the wheel axle between the wheels. The post is rotatable relative to the wheel unit.
A drum for a roll-up closure, the closure having a door of hinged together slats, one end of the door adapted to be mounted on the drum, the door adapted to be wound on the drum as the drum is rotated. The drum has a wall defining its shape with a depression in the wall extending both inwardly and across the width of the drum. The cross-section of the wall defines an increasing spiral from one side of the depression to the other side of the depression. An extension of the wall extends from the one side of the depression towards the other side to partially close the depression. The partially closed depression is shaped to receive the one end of the door to mount the door on the drum.
A spring tensioning unit for a roll-up closure, the closure having a pair of end plates and an axle rotatably mounted on the endplates.

A hinge assembly having a hinge member and two adjacent panels. The hinge member is elongated with an inner surface that is slightly dished. There is an entry slot in the center of the inner surface extending inwardly into the member, the entry slot diverging into two curved branch slots extending in opposite directions. Each panel has a curved hinge element at each side of the panel with one hinge element curved in one direction and the other hinge element curved in the other direction, both hinge elements also curved toward each other. The hinge elements of the adjacent panels are mounted in the hinge member, the hinge elements passing together into the central slot and then diverging from each other into the branch slots. The panels can be moved in the slots between a folded position where they are almost parallel and an unfolded position where they are against the inner surface, almost aligned, and extending away from each other.
