The latch engages the bore of the hook portion to lock the front cover with the case member, and the lever is turned to move the latch and disengage the latch with the bore of the hook portion of the lock member to unlock the front cover with the case member.

A magnetic latch for fastening a closure member to a support. The magnetic latch comprises a latch bolt assembly comprising: a first elongated housing configured to be mounted with its rear side facing either the closure member or the support; a second housing connected to and positioned underneath the first housing, the second housing being rotatable with respect to the first housing around the vertical direction between a first rotational position in which the latch bolt assembly is operable for a right-handed closure member and a second rotational position in which the latch bolt assembly is operable for a left-handed closure member; and a latch bolt mounted in the second housing. The different rotational positions of the second housing allow using a horizontally moveable latch bolt while retaining a symmetrical placement on the closure system irrespective of the handedness of the closure member.

A latch mechanism for a bathroom stall door includes: a sliding latch having an engagement portion and a user contact portion, the user contact portion having a latch movement section and a door movement section; a door bracket configured to attach to a door and that restrains movement of the sliding latch relative to the door, the movement being restrained to a sliding movement; and a latch catcher configured to attach to a frame adjacent to the door, the latch catcher receiving the engagement portion of the sliding latch when the sliding latch is in a latched position. The latch movement section is configured to translate movement of the user to movement of the sliding latch between an unlatched position and the latched position, and the door movement section is configured to translate movement of the user to movement of the door between an open position and a closed position.

The invention relates to a child safety locking mechanism for a cupboard comprising first and second movable doors 3a, 3b and a fixed frame 3, and comprising first and second latching means 1, 31 and a catching means 2, the first and second latching means 1, 31 each comprising a retractable rod 4, 34 removably engageable in a corresponding recess 5a, 5b in the catch means 2 and retractable by a user operable unlocking means 12, 42 against the action of a spring 6, 36 which spring 6, 35 restores the retractable rod 4, 34 to the catch engaged position when the user releases the user operable unlocking means 12, 42; wherein the user operable unlocking means 12, 42 includes secondary locking means 13, 43 which normally prevents the operation of the user operable unlocking means 12, 42 and which must be unlocked before the user operable unlocking means 12, 42 can be operated. The secondary locking means is unlocked by a rotating, sliding or pressing-in action, and corresponding the unlocking means 12, 42 may be released by a rotating, sliding or pressing in action, and that the direction movement required to unlock the secondary locking means 13, 43 is different to the direction of movement required to release the unlocking means 12, 42. The retractable rod 4 includes a first catch engaging end 4a and second opposite operating end 4b which includes a gear rack 9, and the user operable unlocking means 12 includes user engaging surface and is connected by a shaft 11 to gear wheel 10 which engages the gear rack 9 to slidably move the retracting rod 4 when the engaging surface of the user operable unlocking means is rotated by an adult user.

A bolt module is disclosed. The bolt module comprises: a bolt moveable between a thrown position and a retracted position; an anti-thrust member moveable between a release position in which the bolt can be retracted and a plurality of blocking positions obstructing driving back of the bolt under action of an external force on the bolt and, a first rotor assembly capable of accepting a drive element, the first rotor assembly arranged to drive the bolt and to move the anti-thrust member between the plurality of blocking positions and the release position. Each of the plurality of blocking positions may respectively limit to different extents the driving back of the bolt under action of an external force on the bolt. There is also disclosed a leaf or door comprising the bolt module, wherein the bolt module is mounted on the leaf or door for securing the leaf or door.

A hinge lock for locking a door leaf with respect to a door frame and for pivoting the door leaf with respect to the door frame.
