Abstract
A door closer comprises: an elongate housing 2 for mounting in one of the door leaf or door frame, a plunger 17 disposed in and movable along the housing, a biasing element 4 disposed in the housing and biasing the plunger inwardly of the housing, and a tension member 14 having a first end pivotally connected at a first pivot to the plunger and a second end, an anchor element assembly to which the second end is pivotally connected at a second pivot, and a hydraulic damper 6 for damping the movement of the plunger within the housing, the hydraulic damper including a threaded adjuster pin 52 for adjusting the operation of the hydraulic damper, the threaded adjuster pin being mounted in the plunger adjacent the first pivot and having an elongate head 54 extending away from the plunger and adjacent to the tension member.
