Embodiment Construction

[0020] exist figure 1 , presents a perspective view of the device (1) that is the subject of the present invention, placed on the edge for connecting a flexible ventilation duct and a fan (2) to the main ventilation duct. In order to keep the air under control, the utility connection ( 1 ) connecting the ventilation duct to the main ventilation duct and the fan may here comprise air guiding wings. Said mounting device (1) comprises a flexible ventilation tube (2) at a distance around it, and a fastening ring (5) as a parallel circular extension. The fastening ring (5) is secured by surrounding the flexible ventilation duct (2). Said pipe (2) is tightly fixed by virtue of the circular grooves and protrusions it comprises by easily fitting on said fastening ring.

[0021] The device (1) which is the subject of the invention comprises a mounting projection (3) having a certain length towards the outside. By means of connection means such as screws to be penetrated into mountin...

Abstract

The invention is about a connecting apparatus which ensures the connection of the flexible ventilation ducts to the main ventilation ducts, distribution points and all kinds of fan, device and ventilation equipment, and which, distinctly from the existing connecting apparatuses, is installed by being screwed onto the flexible ventilation duct and thereby where the flexible ventilation duct serves as a natural gasket by being squeezed, and which allows for a more leak-proof, more resistant, more practical, more economic and more flexible connection.

Description

technical field [0001] The present invention relates to a connection device which ensures the connection of flexible ventilation ducts to main ventilation ducts, distribution points and various fans, devices and ventilation equipment and which, unlike existing connection devices, is threaded to The flexible ventilation duct is mounted on and thus the flexible ventilation duct acts as a natural gasket by being extruded and the connection means allows a more leak-proof, stronger, more practical, more economical and more flexible connection. Background technique [0002] In the prior art it is common to use plastic clips and insulating tapes when connecting flexible ventilation ducts to main ducts, certain distribution points, various fans, fixtures and ventilation equipment. On the part of the flexible ventilation duct that will be connected to the main ventilation duct there is a metal end fixed and a plastic clip fits over the joint. After surrounding the joint area with a ...
