ABSTRACT:
A latch device for a hinged door including a resiliently flexible latch bar secured to the door and having a free portion extending along the inside of the door to an end portion, near the door edge, which engages a catch by means of the bending and straightening of the latch bar. Preferred embodiments include a stop bar similar to the latch bar, but extending beyond the opposite door edge to engage another catch to hold the door open. The latch and stop bars are preferably a single bar with two free portions at its opposite ends. The catches have bearing surfaces which distort the bar as the door swings to prepare it to snap into locking engagement with the catches. Access to the latch bar, to allow unlatching, is provided through the door.
