Gate latch

A safety latch attachment for use with a gate mounted for pivotal movement relative to a stationary fence, a latch bar secured to one of said gate or said fence, a latch frame mounting plate secured to the other of said gate or said fence, a latch frame secured to said latch frame mounting plate, a latch member pivotally mounted on said latch frame for movement between latched and unlatched positions, said latch member engaging said latch bar in said latched position, said safety latch attachment including:

• an adapter plate having a planar bottom surface;
• a rectangular notched out portion formed in said bottom surface of said adaptor plate dimensioned to receive a portion of said latch frame mounting plate;
• means for securing said adaptor plate adjacent said latch frame mounting plate in partial overlying relation therewith;
• an aperture formed through said latch frame;
• a hollow cylinder having first and second open ends and mounted on an upper surface of said adapter plate in coaxial alignment with said aperture;
• a plunger received for reciprocal movement in said first end of said cylinder, said plunger dimensioned for insertion through said aperture;
• a rectangular channel member having first and second parallel side walls connected by a transverse wall;
• means mounting said channel member on said upper surface of said adapter plate, said first side wall of said channel member in abutment with said second end of said cylinder;
• a coil spring received in said cylinder, said spring having a first end secured to said first side wall of said channel member and a second end secured to said plunger, biasing said plunger through said aperture;
• means rotatably mounting a pulley within said channel member, between said first and second side walls;
• a cable guided by said pulley;
• a passage formed through said first side wall of said channel member in alignment with said cylinder;
• and
• said cable extending through said passage and said spring and having an end secured to said plunger, whereby said plunger may be moved out of said aperture by tensioning said cable.

A gate latch for use with a gate mounted for pivotal movement relative to a stationary fence, comprising:

• a latch bar;
• means for mounting said latch bar on one of said gate or said fence;
• a latch frame mounting plate;
• means for mounting said latch frame mounting plate on the other of said gate or said fence;
• a latch frame on said latch frame mounting plate in alignment with said latch bar;
• said latch frame having a recessed portion dimensioned to receive said latch bar;
• a latch member having first and second ends;
• means pivotally mounting said latch member on said latch frame, between said first and second ends, for movement between latched and unlatched positions;
• said latch member having an arcuate curvature adjacent said second end dimensioned to partially surround said latch bar in said latched position;
• an aperture formed through said latch frame;
• a hollow cylinder having first and second open ends and mounted on an upper surface of said latch frame mounting plate in coaxial alignment with said aperture;
• a plunger received for reciprocal movement in said first end of said cylinder, said plunger dimensioned for insertion through said aperture;
• a rectangular channel member having first and second parallel side walls connected by a transverse wall;
• means mounting said channel member on said latch frame mounting plate, said first side wall of said channel member in abutment with said second end of said cylinder;
• and
• a coil spring received in said cylinder, said spring having a first end secured to said first side wall of said channel member and a second end secured to said plunger, biasing said plunger through said aperture.
