Lock for a sliding door or gate

A lock for a sliding door or gate comprising:

• a frame;
• a latch bolt comprising a shaft portion and at least one laterally projecting wing on the shaft portion, the shaft portion projecting in a predetermined direction out of the frame and being rotatably mounted on the frame according to a rotation axis extending in said predetermined direction;
• and
• a latch bolt operating mechanism arranged to rotate the latch bolt from a first angular orientation, wherein the lock wing of the bolt is in a locking position, to a second angular orientation, wherein the lock wing of the bolt is in an unlocking position and vice versa, the latch bolt operating mechanism comprising a resilient element arranged to urge the latch bolt from its second to its first angular orientation,
• characterised in that said wing has a lateral surface defining a screw-like curve around the rotation axis of the latch bolt enabling to convert a translational motion of the latch bolt in said predetermined direction into a rotational motion of the latch bolt from its first to its second angular orientation.
