Abstract: The invention pertains to a new type of fitting for lift-slide doors or windows with at least one running shoe located on a bearing element so that it can be moved in a longitudinal running shoe axis relative to the bearing element for raising and lowering the door or window sash and with a coupling element that connects the at least one running shoe for this movement with a drive element, for example with a push rod, located on one vertical section of the sash frame.

Abstract: A locking device for a door, window, or the like, has a main lock casing, at least one additional lock casing and at least one pushrod connecting the additional lock casing with the main lock casing. The additional lock casing has a retractable latch bolt, which can be freely pushed out of the latch position into the additional lock casing, which can be pushed into its locking position by means of a spring and/or a gear. The latch bolt on its side located opposite a leading incline and in the area of the latch end has a protrusion, on which a latch restoring lever acts, and the latch restoring lever has a first catch, by means of which a pushrod is taken along in the, and; one direction, a second catch, by means of which it is taken along by the pushrod in the other.

Abstract: A locking device for a door (1), window, or the like, with a main lock casing (2), at least one additional lock casing (3) and at least one pushrod (11) connecting the additional lock casing (3) with the main lock casing (2), wherein the additional lock casing (3) has a retractable latch bolt (10), which can be freely pushed out of the latch position into the additional lock casing (3), which can be pushed into its locking position by means of a spring (28) and/or a gear, and wherein the latch bolt (10) on its side located opposite a leading incline (22) and in the area of the latch end (34) has a protrusion (43), on which a latch restoring lever (40) acts, and the latch restoring lever (40) has a first catch (46), by means of which a pushrod (11) is taken along in the one direction,

Abstract: A lock for a door including a latch bolt and a further bolt mounted in a housing for parallel displacement relative to the housing. A bearing is fixed in place in the housing and along with a turning element and a two-armed hinged lever, also mounted to the housing operate on the latch bolt and the further bolt. The two arms of the two-armed hinged lever are pivotably connected with each other at their free ends with one of the arms receiving the fixed bearing between its ends, and with one of the arms being connected to the turning element and the other of its arms being connected to the further bolt.
