An apparatus provides a latch with a rotary dial and a leaf spring with teeth that extend from a frame into an engaging position. Inward axial movement of the dial causes the dial to deform the leaf spring and the teeth to extend into the engaging position. In the engaging position, the dial supports the teeth and resists forces that might otherwise cause the teeth to unlatch. In the engaging position, a catch in a track on the dial engages a pin of the frame to maintain the engaging position. From the engaging position, a rotation of the dial unseats the catch and allows the dial to move axially outward and the teeth to recede into the frame.

Dial cam latch

A latch includes a housing, a leaf spring, a tooth, and an actuator. Motion of the actuator against the leaf spring causes the leaf spring to deform and the tooth to extend from the housing to engage a keeper.

Leaf spring latch

A latch includes a pin held in a set position by a trigger. The trigger, when depressed, allows the pin to extend from a chassis and engage a rack, preventing the chassis from being removed from the rack. A handle allows the pin to be retracted, with a reset catch maintaining the pin in the retracted position. The trigger, when released, dislodges the reset catch and the pin returns to the set position maintained by the trigger.

Latch with auto-close

A latch includes a cam arm that follows a serpentine groove in the latch handle where curves of the groove create catch positions that define extended and retracted handle positions. In one of the handle positions, an arm of the handle abuts a toothed arm and urges the toothed arm to a latching position in which a tooth is extended. In the other handle position, the arm retracts from the toothed arm, allowing the tooth to retract.
