WINDOW AND/OR DOOR DEVICES Russian patent published in 2003 - IPC

FIELD: applicable for actuation of the locking mechanism. SUBSTANCE: the devices have a means of manipulation that is installed on the thrust casing, rigidly in the axial direction for turning. The means of manipulation has a polyhedron for actuation of the locking mechanism, fastened in the journal of the handle without any possibility for turning. Two dogs movable relative to each other may be connected between the adjacent surfaces directly or with the aid of connectors with a force and/or geometric closing in such a way that the transmission of torque from the handle to the polyhedron may be accomplished, and from the polyhedron to the handle, quite the reverse, may be locked as a result of the shift at least of one connector in the direction of the force action. The main part of the polyhedron dog may concentrically enveloped by the handle dog, having wings with pushing surfaces on two half-couplings, which transfer the spring-loaded rolling pins located in pairs that are retainer in a wedged restrained space. The angular sections of the polyhedron dog cavities act on the rolling pins. The middle parts of the handle dog may direct the compression spring loading the fixing balls in outside direction, corresponding to which on the means of edge limitation are the recesses of the thrust casing. The modified means of manipulation features an enhanced stability to the action from the outside and is easily activated from the inside. EFFECT: enhanced reliability. 28 cl, 19 dwg
