A door closer comprises a housing mountable to one of a door or a door frame, an arm having a first end pivotally attached to the housing and a second end connected to the other of the door or door frame, the arm being movable between a neutral door position and first and second open door positions up to 180 degrees from the neutral position in opposite directions, and opposing first and second racks movable relative to each other and relative to the housing. Each of the first and second racks has a first end adapted to engage a piston within the housing. The door closer further comprises a pinion within the housing pivotally connected to the arm first end and engaging teeth of the first and second racks, a piston having a first end adapted to engage the first end of the first and second racks, and a spring compressible by an opposite end of the piston. Movement of the arm from the neutral position to one of the first or second door open positions rotates the pinion and urges the first end of the first or second rack into engagement with the piston first end, the piston compressing the spring until the door reaches one of the first or second door open positions, and movement of the arm from the neutral position to the other of the first or second door open position rotates the pinion in an opposite direction and urges the first end of the other of the first or second rack into engagement with the piston first end, the piston compressing the spring until the door reaches the other of the first or second door open position.

Dual direction door closer

A hold open arm assembly for a door closer to facilitate access to the holding feature by a resiliently biased plunger on a closer arm that is mounted to a soffit plate. A soffit ramp may extend from the soffit plate to provide a sloped surface for engagement by the plunger, leading to the plunger being gradually depressed as the door continues to open and receiving in a recessed area of its free end a rivet head at the soffit plate to hold the door open. When the first arm member pivots relative to the soffit plate and the plunger approaches the head, the plunger engages the sloped surface of the soffit ramp, slides along the sloped surface toward the head, and receives at least a portion of the head in the opening in the free end.
