Claim:
A door latch assembly comprising: a door moved between a latched and an unlatched state; a keeper plate mounted to a door frame of the door, the keeper plate defining a keeper opening; a latching mechanism including: a sliding latching platform for movement within the door between a latched position, in which the latching platform is received through the keeper opening, and an unlatched position, the sliding platform having a nose and a pair of sidewalls, extending from the nose, each sidewall including a slot and a sized hole at an opposite end; a pair of latching elements pivotally mounted to the sized hole of the latching platform, each latching element comprising a slot and a latching head, each located at an end opposed to the pivotal end and facing away from each other; a spring member located between the latching heads; an operating shaft received through the slots of the latching platform, the shaft having an operating flat middle section that is positioned within the openings of the latching elements; a flat spring member operatively connected to the operating shaft middle section; operating means connected to each end of the operating shaft to move the operating shaft between an operating and a non-operating state; wherein, when the door is positioned within the door frame, the latching platform is received through the keeper opening, and the latching heads will retract within the latching platform; when the latching heads have fully passed through the keeper opening, the spring member will bias each latching head away from the latching platform, causing the heads to hook behind the keeper plate and effectively positioning the door in the latched state; wherein, in order to position the door in the unlatched state, operation of the operating means will rotate the operating shaft, so that the middle section will engage the openings of the latching elements, to move the latching heads within the latching platform, allowing retraction of the latching platform from the keeper plate.
