Abstract:
1. A self-latching device for fastening a hinged closure member, which device comprises: a frame arranged to be mounted on the hinged closure member; a latch bolt mounted on said frame so as to be movable in a predetermined direction between a latching position and a retracted position, the latch bolt being arranged to be moved towards its retracted position by contact with a striker element when closing the closure member and the predetermined direction wherein the latch bolt is movable being a substantially horizontal direction when the latching device is mounted in an upright position on the closure member; a latch bolt spring arranged to bias the latch bolt into the latching position; and operator means mounted on top of the frame so as to be operable from both sides of the closure member and connected by means of a latch bolt operating mechanism to the latch bolt for moving the latch bolt from the latching to the retracted position, the latch bolt operating mechanism comprising: an operator shaft which has a longitudinal axis, which is pivotally mounted around said longitudinal axis on said frame and which has an upper and a lower end, the operator means being connected to the upper end of the operator shaft to enable to rotate the operator shaft by means of the operator means; and at least one cam element provided on the lower end of the operator shaft and arranged to move the latch bolt against the biasing force of the latch bolt spring to its retracted position upon rotation of the operator shaft in at least one rotational direction.
