Abstract: The collapsible container includes a rectangular bottom wall, two opposed vertical side walls, two opposed vertical end walls, hinge means for pivotally and releasably attaching the side and end walls to the bottom wall, and means for locking the side and end walls in an erected position. The hinge means preferably includes a first wall having a first hinge portion with an integrally formed pivot pin adjacent a bottom edge and a second wall having a cooperating second hinge portion with an integrally formed, semi-cylindrical surface. Preferably the second hinge portion further includes an integrally formed projection disposed adjacent the semi-cylindrical surface spaced along a periphery of the second wall. The projection is movable out of axial alignment with the semi-cylindrical surface to permit insertion of the pivot pin and returnable into axial alignment with the semi-cylindrical surface to releasably secure the first wall in pivotal relation to the second wall.

Abstract: A frame extending around an opening in a vehicle roof is adapted to support the perimeter of a curved glass panel to close off the opening. A pair of bayonets projecting in spaced relation to the underside of the forward edge of the panel mates with an aperture in the frame when the panel is inclined with respect to the roof to act as a pivotable hinge allowing motion of the panel between a closed position and that inclined position. A two part fastener for the rear edge of the panel includes a handle pivotably connected to the underside of the panel and a tongue pivotably connected to the handle and adapted to be retained in a lock member in the frame. The handle acts as an over-center linkage to bend the panel against its curvature, forcing its perimeter into intimate engagement with the frame or may be extended to maintain the panel with its rear edge tilted upwardly away from the opening.

Abstract: A bi-fold door assembly of the type adapted to be mounted in a doorway having opposing parallel jambs and a connecting header, the bi-fold door assembly including at least one jamb door pivotably secured to one jamb and a lead door having means hinging the same to the jamb door. In one embodiment, a header track having a U-shaped cross section having inner opposing legs with longitudinally disposed and transversely spaced flanges defining a longitudinal slot thereinbetween. The flanges slidably support a pivot assembly carried by the lead door to guide the lead door between its opened and closed positions.
