Abstract: A front panel mounting arrangement for a sheet filter in an air moving appliance including a frame, and when the sheet filter is in a mounted condition can be incorporated in the front panel from alternate directions, being the top and bottom of the panel, while the panel is capable of limited movement away from the frame and also capable of relative inclination with respect to the frame.

Abstract: A hinge for mounting an access door on a room air conditioner has a hinge member having a tang at one end engaging a slot on the air conditioner front frame to mount the hinge member in a fixed position. The other end of the hinge member has a pair of resilient legs interspaced by a projection and which carry projecting trunnions on their outer ends. The door has a notch in its side having opposed side walls with bores that receive the projecting trunnions to pivot the door about the hinge member. The hinge provides a self-latching arrangement by a projecting, resilient tongue on the hinge member which engages a projecting lug on the door to resiliently bias the door to a closed position when it is within a predetermined distance from the closed position.
