摘要

Invention applies to mechanics. The invention aims to simplify the product structure. The window and balcony door closing lock consists of a casing (1) made of two side walls (2) and a front wall (3). Inside the casing there is a latch (4) with a single hole to install handle axles (5) and two holes of the same size to put in freely the axles (6). On the one axle (6) there is an upper closing lever (7), on the other, the lower lever (8). Closing levers (7, 8) are connected to pins (9). The loose ends of the pins at the closing moment are fixed in sleeves (10) installed in an immovable frame, and in an opening position, the ends are in deflecting elements (11), installed in a movable frame. Both side walls (2) of the casing (1) have a single hole for the handle (5) axle installation and two of the same size circle arch shaped deflecting cavities (12), which are located symmetrically regarding the vertical axis crossing the handle (5) centre and which are made for the axles (6) sliding. In the front wall (3) of the casing (1) there is an oblong cavity for a latch (4) to come out and move into a receiving element fixed in the opposite frame. The window and balcony door lock is used for vertical opening windows and balcony doors with coupled wings.
