ABSTRACT:
An enclosure latch arrangement including at least one latch assembly for securing a first enclosure portion relative to a second enclosure portion by providing, on the inside of the first enclosure a stationary latch bracket member having a pair of spaced pin members on a common line. The second enclosure portion is provided with at least one latch bar assembly, which includes a spring biased latch actuator in slidable abutting relation with a latch bar secured within the enclosure. The latch actuator is barshaped and has a pair of spaced pawl openings formed in an edge thereof, spaced a distance equal to the spacing between the pin members, with the pawls including cam edges at the point of operative coaction with the pin members. The latch bar has provision for retaining one end of a compression spring member, and the latch actuator has provision for retaining the other end and further includes first and second slotted openings, through which fasteners are passed for engaging the latch bar to secure the parts in sliding abutting relation. The latch actuator has a bent portion at an end thereof to serve as a tool engaging surface for urging the latch actuator against the force of the spring bias. The enclosure is provided with a tool opening in general alignment with, or adjacent, the tool engaging surface for enabling insertion of a tool into the opening for actuating the latch actuator to enable separation of the enclosure portions. The latch assembly further includes a plunger oriented in a direction to bias the first and second enclosure portions apart, whereupon, on closing the separation or plunger spring is compressed, and, upon actuation of the latch actuator, the spring urges the portions apart.
