  • Patent number: 4572156
    Abstract: A fireplace screen assembly arrangement is disclosed which includes a frame assembly upon which glass doors and a pair of mesh doors are mounted for slideable lateral movement between closed and open positions with respect to an associated frame assembly and fireplace. The mesh doors are latched in a closed position, and automatically move to lateral full open positions under the influence of a weight and chain mechanism. When the mesh doors are moved to a closed position of rest, a door and frame latching mechanism engages to hold them in that position. In that position, they are ready to open fully when an operator knob is moved to release the latching mechanism. In this manner, convenient use of the fireplace is enhanced, with the mesh door-opening mechanism permitting a user to easily open the mesh doors for gaining access to the fireplace area.
