SOUNDPROOF WINDOW Russian patent published in 2004 - IPC

FIELD: building units, particularly windows for different buildings and building structures.

SUBSTANCE: window includes casing, outer and inner casements, glass secured by flexible fillers in outer casement and glass pack filled with transparent fluid and arranged by another fillers in inner casements. Window also has soundproofing material connected to inner surface of window casing. Transversal spiral grooves with dovetail cross-section are made in inner casing surface at upper part thereof and in inner and outer casement surfaces adjoining inner case surface. Curvature of transversal spiral grooves formed in inner casing surface in upper part thereof has positive direction of generating line movement, curvature of transversal spiral grooves formed in outer and inner casement surfaces has negative direction of generating line movement.

EFFECT: increased protection against noise due to forming coincident waves of atmospheric air between glass and glass pack so that soundproofing effect of coincident waves is summed with soundproofing effect of glass pack.
