The bolt of a latching mechanism is spring actuated toward a latching position relative to the latch-receptive slot of a latch-catch which is pivotally mounted on the vertical member of a swing gate, and movement of the bolt from a fully latched position to a retracted non-latching position is controlled by a pendulum stop which is normally and gravitationally disposed in interfering relationship with the bolt, whereby an intentional, deliberate, pendulum-stop-displacing action is required on the part of an attendant in order to enable the bolt to be shifted from an advanced, locked position to a retracted position.

A retractable latch for the latch-catch of a gate, said latch comprising a bolt housing, a bolt mounted within said housing for endwise axial movement between fully advanced and retracted positions, means yieldably urging said bolt to a fully advanced position, a hasp connected to said housing and having a central opening defined therein through which a rear end of said bolt passes when said bolt is in said fully retracted position and a pair of through-openings defined therein; and a pendulum stop pivotally attached to said housing in covering relationship with said hasp so that said hasp is interposed between said pendulum stop and said housing, said pendulum stop having an abutment area adapted to be positioned adjacent said hasp central opening for contacting said bolt rear end and preventing movement of said bolt into said retracted position; said pendulum stop having a pair of elongate openings defined therein adjacent said abutment area, each of said elongate openings being positioned for disposition into alignment with said hasp central opening by pivotal movement of said pendulum stop so that said bolt rear end can pass through said aligned central and elongate openings to permit movement of said bolt into said fully retracted position, and pendulum stop being pivotally connected to said housing to assume a position with said abutment area aligned with said hasp central opening under the influence of gravity to be in an interfering relationship with said bolt unless moved to align one of said elongate openings with said hasp central opening thereby preventing the unintentional or accidental retraction of the bolt from a fully advanced position; said hasp through openings each being aligned with one of said pendulum stop elongate openings to receive a locking means when said pendulum stop is in said interfering relationship so that said latch bolt can be locked in said fully advanced position.
