  • Patent number: 6247341
    Abstract: In a lock for sliding door, window or like closure the slider has on its face adjacent the outside wall of the casing a member projecting a predetermined distance which projects through the slot in the locked position of the slider and abuts against the edge surface of the outside wall defining the longitudinal end of the slot. A return spring between the slider and the casing spring-loads the slider towards the outside wall of the casing but allows movement of the slider in the direction perpendicular to the outside wall over a distance at least equal to the predetermined distance.

  • Patent number: 6089625
    Abstract: In a lock for sliding closures a maneuvering member is mounted to pivot about a pivot pin passing through the casing in the transverse direction of a slot and the maneuvering member and the bolt-carrier include, in the case of one of them, a cam surface and, in the case of the other of them, a ram follower roller which cooperates with the cam surface to enable sliding of the bolt-carrier in one direction or the other when the maneuvering member pivots in one direction or the other about its pivot pin.

  • Patent number: 6050617
    Abstract: A lock for sliding door, window or like closure includes a drive member mobile in the longitudinal direction of the casing relative to the casing and includes an arrangement which cooperates with a complementary arrangement attached to the cylinder to enable the drive member to be moved in one direction or the other by means of the key and another arrangement which cooperates with a complementary arrangement of the sliding assembly to enable the sliding assembly to be moved by means of the key.

  • Patent number: 6019400
    Abstract: In a lock for sliding closures two fixing members are disposed at respective corresponding ends of the casing and inserted with the casing into a slot in the closure. A first fixing member has at least one part which retracts elastically in the longitudinal direction of the casing in the direction towards the center of the casing to enable it to pass through the slot in the closure and to return elastically in the opposite direction to engage the corresponding edge surface of the slot.

  • Patent number: 6007113
    Abstract: In a lock fitting for sliding closures the bolt-carrier has at least one slot to receive the tail of a bolt carrying at least one hook and includes at least one screwthreaded hole having an axis perpendicular to the walls of the slot to receive an immobilizing screw for immobilizing the tail of the bolt against the wall of the slot opposite the immobilizing screw. The tail of the bolt includes at least one opening extending in the longitudinal direction of the slot and the screw bears on at least one edge of the opening.

  • Patent number: 5979950
    Abstract: In a lock fitting for sliding closures a bolt-carrier includes a screwthreaded hole with its axis perpendicular to a covering plate to receive a screw for immobilizing a bolt on the bolt-carrier. The covering plate has an orifice for access to the screw and to the screwthreaded hole on the axis of the screwthreaded hole when the bolt-carrier is in its locked position. The fitting includes a plug to blank off the orifice. The plug can be retracted inside the casing to allow access to the screw and then returned to its normal position in which it blanks off the orifice.
