The mounting block and cylindrical fastener assembly is rotatably mounted in the cup-shaped housing. The mounting block and cylindrical fastener assembly allow for rotation of the at least one bail above the plane of the load bearing surface.

Abstract: A barrel hinge having a female barrel portion and two male barrel portions. The female barrel portion has a sidewall with an aperture formed therein, a length, two ends, and an outside surface, and an axial bore, with an interior wall surface and a diameter, which extends from end to end. The male barrel portions each have a main body portion with an outer surface, and a pin extension. The pin extensions have a pin length and pin diameter, the pin extensions having ends, the pin diameter being sized to be received within the interior bore of the female barrel portion. The sum of the pin lengths of the pin extensions of the first and second barrel portions is less than the length of the interior bore of the female barrel portion.

Abstract: A bi-directional handle and latch assembly mountable to a door or other closure. The latch assembly may be operated by either of a first handle or a second handle. The first handle may operate a latch bolt in the latch assembly by rotating the handle in either the clockwise or the counter-clockwise direction, and operate the latch bolt irrespective of whether or not the second handle is locked. The invention employs a simple construction for ease of manufacture, repair, and replacement of the first handle with other handles with different aesthetic or functional outer designs or configurations.
