ABSTRACT:
A fireplace screen arrangement is disclosed which includes a frame upon which a pair of mesh screen doors are pivotally mounted for movement between closed and open positions with respect to the fireplace. A damper assembly is provided for regulating the amount of air which is admitted to the fireplace through the screen arrangement. In order to provide convenient opening of the screen doors, a door-opening mechanism is provided which includes a door-engaging lever fulcrummed for pivoting movement with respect to the frame. An operating knob is operatively connected with the door-engaging lever so that inward movement of the knob moves the screen doors from their closed position. In the preferred embodiment, the operating knob is operatively connected with a movable damper plate for moving the damper plate laterally to regulate air admitted through the damper assembly. In this manner, convenient use of the fireplace is enhanced, with the door-opening mechanism permitting a user to easily open the screen doors for tending the fire in the fireplace.
