SCREWLESS LOCKING NODE FOR LOCK Russian patent published in 2022 - IPC E05B15/02 

FIELD: locking systems.

SUBSTANCE: invention relates to a screwless locking node for locks with a latch or a tab of both magnetic and non-magnetic types, for rigid fastening, without screws, in a mounting socket of a fixed door frame or other supporting element. Screwless locking node (1) for a lock contains box-shaped case (2) with sidewall means (3) limiting cavity (4) adapted to accommodate a latch or a lock of the tab. Box-shaped case (2) is adapted to accommodate the door frame or other supporting element in the mounting socket. Node (1) contains front bar (6) with pass-through hole (7) for the latch or the tab and made in accordance with the geometric shape of box-shaped case (2). The node has means (8) for fixing in the mounting socket. The fixing means contains one or more locking legs (8) made as a whole on the back part of front bar (6) and protruding from it, and made with the possibility of elastic deformation from the initial configuration (R) to an extended fixation configuration, in which they are engaged with a limiting surface of the mounting socket. Box-shaped case (2) contains one or more pressure surfaces (9) made with the possibility of pushing apart and pressing one or more locking legs (8) to the specified limiting surface to achieve the specified extended fixation configuration.

EFFECT: creation of a locking device with the possibility of fixing the wooden door frame in the mounting socket without the use of screws or special tools is provided, which does not require very precise mechanical processing of the mounting socket, which allows compensating for possible gaps and tolerances for mechanical processing and guaranteeing reliable fastening.
