EASILY RELEASABLE STRUCTURE (VERSIONS) Russian patent published in 2020 - IPC E06B5/12 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to light-released structures displaced at excessive pressure arising as a result of explosion, intended for attachment in window openings of buildings. Light-released structure consists of a fixed box and an easily releasable element with filling, connected to each other by means of a safety shut-off device with a breakable element. At that, the fixed box is made in the form of a L-shaped profile, and the easily released element is made of a T-shaped profile, the edge of which is connected to the inner side of the L-shaped profile by means of a safety shut-off device, and one of inner surfaces of T-shaped flange is conjugated with L-shaped profile, while other inner side of flange of T-shaped profile is connected to filling. Invention also includes versions of design with a rotary loop of easily releasable one and two versions with a production flap in different versions (with a light-released element with a rotary loop, locking hardware and without).

EFFECT: technical result consists in simplification of installation process of easily releasable structure in window opening at maintenance of high reliability of operation, as well as in possibility to manufacture structure completely in factory conditions.
