MECHANISM OF HINGED LATCH Russian patent published in 2014 - IPC E05F3/22 

FIELD: construction.

SUBSTANCE: as an operational force a natural phenomenon is used - atmospheric pressure. The main structural component of the mechanism - a body reacting to atmospheric pressure - is a geometric shape - a box, square in cross section. The body is manufactured by compression from an airtight elastic resilient material and has four solid faces, four elastic ribs, and instead the two end faces - two elastic dome. The body is sealed, and when negative pressure is created, acts as a pivot of four sections, being deformed by force of atmospheric pressure into a rhomboid parallelepiped with a sharp angle of 45°. In the mid-points of four faces of the parallelepiped - shaped body there are stops formed that when bound up in pairs can increase the degree of vacuum and atmospheric pressure, the force of impact, without compromising the angle of the rhomb below 45°. The mechanism is attached by one face to the side wall of the furniture, and by an adjacent face - to the door of the furniture.

EFFECT: reliable and efficient work of a hinged latch and ability to hold the door in a closed and open position with a lock effect.
