Abstract

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.
