FIELD: construction.
SUBSTANCE: proposed invention related to fittings that are arranged between a sash and a fixed frame of a window, a door or a similar one, which are hidden and include a rotation axis of the sash, which provides the possibility of sash movement in the plane parallel to the frame plane and perpendicular to the rotation axis of the sash normal to the main plane of the fixed frame at opening of the sash by means of an automatic control device arranged on a guide. With that, the sash is movable, and an automatically controlled drive is intended for movement of the sash, due to which the sash can move to the frame in the guide arrangement direction. Due to the above, total weight of the sash can be relocated at any moment onto the frame through a fixed guide for moving away. According to this disconnection way of load-carrying elements and sash movement control elements, receiving force of the sash can be increased considerably in comparison to the axis of the hinge, which is supported from the guide only.
EFFECT: creation of flush fittings that on one hand have a simple configuration and on the other hand are capable of retaining a sash of heavy weight; with that, it is possible to use narrower guides, which allows reducing the surface area required for installation.
