METHOD AND DEVICE TO CONTROL VERTICALLY OR HORIZONTALLY MOVING GATES WITH PROTECTION OF PLANE OF GATES CLOSURE AGAINST INTERFERENCE Russian patent published in 2012 - IPC E05F15/00 

FIELD: construction.

SUBSTANCE: invention relates to the method and device to protect a plane of gates closure against interference. The method to control gates (1), which are arranged as capable of displacement in a rectangular opening (4) of gates from a position of opening into a position of closing, where near an angle of a rectangle of gates opening, with the help of a long-range detector (12) in an angular range, preferably of 90°, in the plane of gates motion, a beam of a long-range detector is rotated, values produced during such rotation movement from measurement of distance of which or relative distance values trigonometrically calculated into dimensions of gates accordingly as the beam of the long-range detector falls onto the front edge (9) of the gates and onto limitation of the rectangular opening (4) of the gates parallel to the direction of gates movement are compared with appropriate limits values of distance measurement stored in memorising facilities or relative limit values of distance measurement measured as trigonometrically recalculated into gates dimensions, and if there are distance measurement values, which are less compared to them, a warning signal is generated, which causes stop and/or reversing.

EFFECT: simplified system of gates control.
