DEVICE FOR EVACUATION IN CASE OF FIRE Russian patent published in 2020 - IPC E06B3/00 

FIELD: devices for evacuation in case of fire.

SUBSTANCE: invention relates to devices for evacuation in case of fire, mainly from lower floors of a building, for example, shopping and entertainment centers, cinemas, etc. Evacuation device in case of fire comprises a door mounted in the opening of the vertical wall and fixed in the upper part of the opening by means of a locking latch connected by means of a rod to the core of the traction relay, automatically actuated by wires by means of a sensor mounted inside the room, with possibility of door rotation in vertical plane outward relative to hinge of horizontal axis made in lower part of door, and spring-loaded relative to vertical wall by means of torsion spring, one end of which is fixed on door, and the other on the wall, is additionally equipped with a duplicating manual drive with a rope-and-block system actuated by means of a handle. According to the invention, the door, when in an open position, is set on the horizontal support surface by the entire outer plane, door thickness is comparable to thickness of vertical wall and is made composite of different materials, plane with lower density is located inside, and plane with higher density is located outside, with displacement of common center of gravity of door towards outer side of wall, lower support surface and upper surface of the opening interacting with the lower and upper end surfaces of the door, respectively, are sloping towards the outer side of the wall, from the inner side of the wall above the upper part of the opening with upper spring flat pushers, lower ends are pressed and interacting with upper part of door plane in closed position of the latter, hinge of horizontal axis of door turn is made near horizontal support surface and is fixed on lower edge of wall opening and lower end of plane with higher density of door, hinged horizontal door rotation axis is shifted horizontally towards vertical line of center of gravity, in addition, the outer surface of the door at the point of abutment to the hinge of the horizontal pivot axis is made with a bevel horizontally throughout the width of the door with possibility of corresponding interaction with a similar slant made on the vertical wall, when the door is open, the rope-and-block system of the backup drive and the traction relay with the latch are made in the grooves of the vertical wall array and are located below the level of the inner vertical plane of the wall.

EFFECT: technical result consists in expansion of operational capabilities due to efficiency in use.
