ABSTRACT:
A latch apparatus for doors and gates usable with swinging or sliding doors has a mounting bracket which is fixed to a door frame adjacent the door with a pair of converging guideways for retention of a keeper having a slidable tongue which may be removably inserted into the guideways. Extending outwardly from the tongue is a rigid L-shaped strap which fits about and retains a corner of a door to restrain swinging or sliding of the door relative to the strap. The tongue lockably cams within the guideways when force is applied against the strap so as to force the door. Additionally, the lateral sides of the tongue are provided with camming edges which engage a roughened surface within the guideways to further lock the tongue within the guideways. Each lateral side of the tongue has a fulcrum which bears against the guideways to permit the tongue to be sharply pivoted about the fulcrum by an operator so as to shatter and dislodge ice and accumulations in the guideways which would otherwise interfere with operation of the latch.
