Abstract: A chain support mechanism for use with an openable frame component and a method of using such a chain support is provided, where a chain actuator is provided in a housing, the chain actuator including a push-pull chain which chain can bend in one direction only, the housing mounted with its longitudinal extent along one frame component with the chain attached to the openable frame component where the chain actuator may be manipulated to extend or withdraw the chain from the housing, thereby moving the openable frame component, and where the chain support mechanism includes a first arm pivotably fastened to the housing and a second arm pivotably fastened to the openable frame component, where the distal end of the first arm and the distal end of the second arm are pivotably connected by a sliding member, against which sliding member the chain may slide.
