Abstract
A latch has a pop-up knob that provides a handle for pulling on a door when the knob is extended. The door can be closed with the knob either up or down. With the knob up, the latch pawl can be disengaged from a keeper attached to the door frame by pulling the door open. With the knob down, the latch pawl remains in an extended position behind the keeper and the door cannot be pulled open. The knob can be selectively retained in the down position, and placing the knob in the down position results in the rotational movement of the latch pawl being blocked.
