Abstract:
A door closing apparatus adapted for use with a door frame comprising an elongated header and a pair of side jambs arranged to define a door opening, and wherein a door is adapted to be mounted an said frame for pivotal movement about an axis, wherein the improvement comprises:a base adapted to be mounted on said header;a closer mechanism mounted on said base and having a first shaft adapted to be oriented perpendicularly with respect to the header axis of elongation, said closer mechanism being operatively arranged to selectively urge said first shaft to rotate relative to said closer mechanism;a second shaft mounted on said base for pivotal movement relative thereto, said second shaft being substantially aligned with an axis with respect to which said door is constrained to move;a first arm mounted on said first shaft for rotation therewith;a second arm mounted on said second shaft for rotation therewith; anda link pivotally connected to said first and second arms at respective locations eccentric to the axes of said first and second shafts;whereby a force transmitted by said closing mechanism may be transmitted through said first shaft said first arm, said link, said second arm and said second shaft to urge said door to pivot in one direction about its axis.
