DEVICE FOR WINDOWS OR DOORS Russian patent published in 2011 - IPC E05B17/00 

FIELD: construction.

SUBSTANCE: device comprises a support body, a handle and a polyhedron. The support body is designed for fixation on a door or a window. The handle is installed on a support body or in it without possibility of displacement in axial direction, but also with the possibility of rotation. A polyhedron serves for mechanical engagement of the device with the mechanism integrated into a door or window. At the same time the polyhedron protrudes with a section of polyhedron beyond the support body, and also the engagement system formed between the handle and the polyhedron to transfer torque from the handle to the polyhedron and to lock its transfer from the polyhedron to the handle. Length of a polyhedron section protruding beyond the support body and inserted into a frame of a door or a window as the support body is inserted into a door or a window is adjusted automatically. The polyhedron passes in the engagement system with the possibility of displacement in longitudinal direction, but without the possibility of slippage, and enters through it into the handle. The engagement system has two grips provided between the handle and the polyhedron, which at the specified gap along the angle of rotation between the gripping surfaces are engaged to each other with a force and/or geometric closure so that the possibility is provided to send a movement to a polyhedron, which accompanies the handle actuation. The device includes the first grip, which is connected to the handle without the possibility of slippage, and there is the second grip, which receives the polyhedron without the possibility of slippage, but with the possibility of displacement in longitudinal direction.

EFFECT: invention makes it possible, when installing onto a window or a door, to automatically take into account thickness of a frame or a profile with preservation of its safety and protection function with the purpose of always reliable engagement with the mechanism integrated into a door or a window.
