PROFILE SET FOR HEAT-RETENTION AND SOUND-PROOF DOOR OR WINDOW SASH PULLEY Russian patent published in 2004 - IPC

FIELD: building, particularly window or door structures formed of polyvinylchloride (PVC) profiles.

SUBSTANCE: profile set includes at least hollow frame profile with water-removal grooves and hollow leaf profile abutting frame profile and reinforcing U-shaped profile. Leaf profile contacts frame profile through packing members secured to inner sides of frame and leaf profiles along perimeter thereof. U-shaped profiles for hollow frame chamber and hollow leaf chamber are identical. Flanges of U-shaped profile face each other and are offset relative each other half the distance between profile flanges such that cavities are formed between stepped lower wall of leaf profile and opposite inclined part of frame wall into which single-chamber profile is arranged. Single-chamber profile has longitudinal rib with orifices for water drainage, plate bounded by rib contacting with inclined part of frame wall and packing member formed in upper part thereof contacting with medium vertical area of leaf profile. Longitudinal rib extends at an angle of 30^o-60^o, preferably 45^o towards inclined part of frame wall. Rib bounding plate extends at an angle of 120^o - 150^o relative longitudinal rib. Plate extensions rest upon frame wall. Plate and is arranged as spacer. Relation between volumes of chambers is 1:(0.8 - 1.2). Packing members have bends facing cavities formed by packing means and providing additional tightening of packing members when air stream is introduced into cavity.

EFFECT: increased efficiency of structure cavities cleaning when packing dent is located in open position or in selected position.
