A tool-operated latch has a body which is mountable on the back side of a door panel adjacent an elongate opening and a hole formed through the door panel. An elongate latch lever is pivotally carried by the body and is movable between a latched position wherein the latch lever is nested with respect to the elongate door opening, and an unlatched position wherein the latch lever is extended with respect to the elongate door opening. A tool-operable actuator is journaled by the door panel hole and by the latch body, and is movable by a specially configured tool between locked and unlocked positions. A pawl is pivotally carried by the body for movement between a retaining position wherein it engages the latch lever to releasably retain the latch lever in its nested, latched position, and a releasing position wherein the pawl releases the latch lever thereby permitting the latch lever to be moved to its unlatched, extended position. The tool-operable actuator provides a cam member which cooperates with the pawl to effect movement of the pawl from its retaining position to its releasing position as the actuator is moved from its locked position to its unlocked position.

A flush-mountable, tool-operable latch suitable for mounting on a door panel or the like to releasably retain the door panel in a closed position, comprising: (a) a body having wall portions which define an elongate, forwardly-facing recess, and having mounting formation means on opposite sides of the recess for mounting the body on a door panel with the forwardly-facing recess aligned with an elongate opening formed through the door panel; (b) an elongate latch lever pivotally connected to the body and having: (i) a strike-engaging formation which is movable between a latched position wherein it is engageable with a strike for retaining the door panel in a closed position, and an unlatched position wherein the strike-engaging formation is withdrawn to permit the door panel to move from its closed position to an open position; and, (ii) an elongate operating formation which is movable between a nested position relative to the forwardly-facing recess, and an extended position relative to the recess, the operating formation being configured to reside (1) in its nested position when the strike-engaging formation is in its latched position, and (2) in its extended position when the strike-engaging formation is in its unlatched position; (c) a pawl pivotally connected to the body for movement between a retaining position wherein it engages the latch lever to releasably retain the latch lever with its formation in their nested, latched positions, and a releasing position wherein the pawl releases the latch lever thereby permitting the latch lever formations to be moved to their unlatched, extended positions; (d) a tool-operable actuator connected to the body for movement between locked and unlocked positions, including: (i) tool-receiving means for receiving a specially configured tool and being operable to move the actuator in response to movement of such received tool; and, (ii) a cam surface which operably connects with the pawl, which permits the pawl to assume its retaining position when the actuator is in its locked position, and which effects movement of the pawl to its releasing position when the actuator is moved to its unlocked position; (e) first biasing means for biasing the latch lever away from its latched, nested position, toward its unlatched, extended position; and, (f) second biasing means for biasing the pawl away from its releasing position toward its retaining position.
