TUBULAR VENTILATION DEVICE Russian patent published in 2015 - IPC E04D13/17 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, specifically to the tubular ventilation devices installed on the roof, and can be used in ventilation systems of buildings and structures, mainly in ventilation systems of the pitched roof. Tubular ventilation device, comprising pass element, tubular element and deflector made of polymeric material, wherein the pass element is designed in the form of flat square base with bulge in the centre in the form of hemisphere, in which the figure hole is made, which permits at turn around its axis at 90 degrees relative to the tubular element to apply the device on roofs with different inclination angle from 0 to 55 degrees, and the tubular element is designed with conicity and contains skirt in its bottom part in the form of hemisphere truncated from one side, which is rigidly secured with bulge of pass element during installation, and also the flat seat ring in the upper part, comprising recesses for connection and protrusions for fixation in slot-type recesses of adjusting protrusions of the inner surface of deflector.

EFFECT: increase of functionality of the device due to the expansion of the range of slopes of the roof, for which it can be used, reduction of the number of components in structure and simplification of its assembly and installation at the increase of reliability of fastening, and also due to the increase of traction in the device when using the conic tube.
