DOOR SYSTEM Russian patent published in 2020 - IPC E05D15/10 

FIELD: construction.

SUBSTANCE: door system comprises at least one door leaf for closing a door opening defined by at least a first door pillar and a second door pillar; positioning system, for attachment and movement of door leaf between closed position, in which door leaf is located in door opening between first and second door pillar, and open position, in which the door leaf provides access to the door opening. At that, positioning system comprises suspension bar, in which two opposite ends rest on support structure in first suspension point on side of first door pillar and in second suspension point on side of second door pillar. Suspension element connects the door leaf to the suspension bar and slides together with the door leaf along the suspension bar between the first and second suspension points. Door system also comprises power drive and guide system. At the same time the power drive is made with possibility of the suspension element translational movement along the suspension rod from the initial position corresponding to the door leaf closed position to the final position corresponding to the open position of the door leaf. Guide system is configured to direct door leaf from closed position to open in initial phase of door leaf turn outside, in which second side edge of door leaf moves in transverse direction from door opening and in lateral direction behind second door pillar; in phase of lateral translational movement of door leaf at least partially away from door opening; in final turn phase inside door leaf, in opposite direction relative to initial rotation outside. At that, each of said two opposite ends of suspension bar makes it possible to slide in horizontal direction perpendicular to door opening, and suspension element is connected with possibility of sliding with nonlinear upper guide located above suspension bar. At that, ends of suspension rod are fixed with possibility of sliding movement or rolling along corresponding first and second lateral guides, which are connected horizontally and transversely with door opening. Lateral guides interact with appropriate auxiliary guide roller of suspension rod ends. Second lateral guide on second side has greater length than first lateral guide, to provide a larger initial crosswise motion to the outside of the second lateral edge of the door leaf relative to the smaller initial motion of the first side edge of the door leaf.

EFFECT: door system; group of inventions also aims at creating a door subsystem comprising said door system.
