Abstract
In a locking device for a sliding door, window or the like, an operating rod is slidingly surface-mounted on the leading edge of the door, window or the like. An entrainment member for the operating rod moves with the rod and bears on the back and the rims of a groove on the leading edge of the door, window or the like to guide the rod inside a passage on the leading edge of the door, window or the like. The entrainment member has a matching opening through which the body of a main bolt can pass so that the main bolt entrains the entrainment member when it is moved by an actuator mechanism of the device.
Claims12
A sliding closure which is capable of being securely closed comprising:
- a leading edge wherein the leading edge includes a U-shaped groove section;
- wherein the U-shaped groove includes a bottom, a first lateral wall, and a second lateral wall wherein the first lateral wall and the second lateral wall each have at least one rim which creates a passage, wherein the sliding closure includes a locking device comprising:
- a lock fitting which includes an actuator mechanism;
- a main locking member projecting from the leading edge of the sliding closure, wherein the actuator mechanism operates upon the main locking member and enables vertical movement of the main locking member parallel to the leading edge;
- a keeper within a fixed frame wherein the main locking member is adapted to cooper ate with the keeper;
- and
- a means for slidingly surface-mounting an operating rod on the leading edge for entraining at least one auxiliary locking member simultaneously with said main locking member, wherein the at least one auxiliary locking member is adapted to cooperate with a second keeper within the fixed frame, wherein the operating rod includes at least one rod portion connected at each end to an entrainment member, wherein each entrainment member is attached to one of the main locking member and the at least one auxiliary, locking member, wherein each entrainment member includes surfaces respectively adapted to slide along the bottom of the U-shaped groove section and an inside face of the at least one rim, and longitudinal lateral edges adapted to guide the entrainment member laterally inside the passage, and wherein each entrainment member also includes a matching opening for passing therethrough a body of one locking member selected among the main locking member and at least one auxiliary locking member of the same type, said matching opening being matched to the cross-section of said locking members.
