ABSTRACT:
A double-action door can be opened along either side edge and in either direction by pushing or by pulling. A pair of vertically disposed and vertically slideable rods is mounted within the door and near each side edge. Each rod has a ball at its outer end and a horizontally operable cam at its inner end. A transverse bar is slideably mounted within the door and is adapted for interacting with all of the horizontally operable cams. Opening the door at one side edge causes the other side edge to function as the hinge edge. The rods near the opened edge move inwardly, as balls are cammed over the lintel and the sill, and the inner ends of the rods force the transverse bar to move sidewardly and simultaneously to force the rods at the hinge side to move outwardly so that their outer ends are firmly seated in cams in the lintel and in the sill. A locking mechanism is also disclosed which insets a pin into the transverse bar when the door is opened and which unlocks by camming over the lintel when the door is closed.
