DEVICE FOR HANGING SEALED DOORS

FIELD: building units, particularly for hanging big doors provided with packing arranged along door opening perimeter. ^ SUBSTANCE: device has lower and upper pedals comprising main and additional door hinges. Main door hinges are connected to door case and have bearings. Additional door hinges are joined to door leaf. Main and additional door hinges have spaced axes so that additional hinge axes are offset relative main hinge axes in direction of door gravity force application. Axis of upper hinge is offset towards door leaf, axis of lower hinge is displaced to door case. Axis displacement is defined by gap between door leaf and door case necessary for providing door air-tightness. Axes of both main hinges are integrally formed with hinge lids, which may rotate around hinge axes. Contact surfaces of hinge body and lid are of spherical shape with centers coinciding with centers of sphere of revolution of main hinge bearings. Due to displacement of additional hinge axes relative main hinge axes in direction of door leaf gravity force action main and additional hinges are out of door gravity force influence. ^ EFFECT: reduced load on door hinges, simplified structure and increased reliability. ^ 3 cl, 4 dwg
