STUDIO COUCH, "EURO LONGUE" TYPE Russian patent published in 2017 - IPC A47C17/13 A47C17/165 

FIELD: personal demand items.

SUBSTANCE: studio couch, "euro longue" type, comprises a stationary frame with a front portion, a rear portion and two side portions; at least two guides mounted symmetrically with respect to each other close to the stationary frame side portions; the seat adjacent to the stationary frame and able to move in the horizontal direction to form a cavity above the stationary frame; backrest mounted on the stationary frame in the rear part so that in the folded position of the couch the backrest is located in a vertical plane. Backrest is able to rotate around the horizontal axis towards the horizontal position in a cavity formed when the seat is extended, forming a sleeping berth; at least one horizontal displacement limiter of a seat; seat attachement fixture; at least one rear roller fixed on each side of the seat near to the rear portion of the seat. Each of the rear rollers interacts with at least with one guide mounted near the side of the stationary frame; at least two front rollers are mounted on the front portion of the seat to be moved over the floor. The upper part of each guide is formed as a flat surface horizontally mounted parallel to the side of the stationary frame, with downward slopes at the sides and flat in the middle portion. The inner surface of each side of the seat is equipped with at least one supporting roller, and on the outer surface of each side of the fixed frame at least one supporting roller is installed with the possibility of mutual movement when the seat is moving. The height of the supporting rollers mounted on the inner surface of the seat sides is different from the height of the supporting rollers mounted on the outer surface side of the stationary frame. When the seat is in the extreme retracted position between the supporting rollers mounted on opposite surfaces, specifically on the outer surface of the stationary frame side and the inner surface of the seat side, there is a maximum distance, and the diameters of supporting rollers are approximately equal.

EFFECT: improvement of operational characteristics.
