PRACTICAL FLEXIBLE CONNECTING APPARATUS FOR VENTILATION DUCT
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, snore practical, more economic and more flexible connection.
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 fans, devices 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.
STATE OF THE ARTIn the previous technique, generally plastic damps and insulating tapes are used when connecting the flexible ventilation ducts to the main ducts, certain distribution points, all kinds of fan, device and ventilation equipment. A metal end is fixed on the flexible ventilation duct's section that will be connected to the main ventilation duct, and a plastic clamp is fitted over the joint. After encircling the joint areas with chemicals such as mastic etc. for sealing and further adherence, the duct, end section and the insulating layers around the duct are tried to be fixed to the main ventilation duct with an insulating tape. While this makes the installation time longer, a long-lasting solution cannot be provided. Additionally, failure to configure the plastic clamp and insulating tape appropriately causes the ventilation ducts to have a worse appearance. Elongation of the installation time results in an increase in the labor cost.
Various structures have been tried to be provided to overcome this problem in the previous technique, in the U.S. Pat. No. 5,741,030 among these, an initial flange with integrated fitting tabs to be fixed on the flat surface of a ventilation duct is mentioned of. While the said flange enables for varying spacing sizes, it can be fixed on rugged sides.
In the U.S. Pat. No. 5,806,830 on the other hand, an apparatus manufactured from one-piece plastic is mentioned of, which is used as connecting flange in joining the main or intermediary ventilation ducts for heating, cooling, waste air and air re-circulation purposes. This apparatus with a tube-iike shape has a vertical flange on the first end section, and fastenino tabs on the other end section.
In the patent application no. US20080093843 however, a configuration and an apparatus are described where a cylindrical base flange is fixed on the gap generated on the air box walls in a heating, cooling, ventilating and conditioning (HVAC) system, and the connection is performed on the connection tabs generated on this flange by virtue of the fastening tabs generated in hook shape in the inner section of the flexible ventilation pipe.
All these improvements and developments in the previous technique could not completely meet the relevant practical, esthetic and economical requirements for the connection of the flexible ventilation ducts. For these reasons, making an improvement in the relevant technical field has become obligatory.
THE AIM AND BRIEF DESCRIPTION OF THE INVENTIONThe aim of the present invention is to present a connecting apparatus ensuring the practical, esthetical, resistant and economic connection of the flexible ventilation ducts to the main ventilation ducts and boxes, distribution points, all kinds of fans, devices and ventilation equipment.

DETAILED DESCRIPTION OF THE INVENTIONIn
The apparatus (1) which is the subject of the invention contains mounting protrusions (3) of certain length towards the exterior. By virtue of connection means such as screws etc. to be penetrated through the mounting holes (4) generated on the said mounting protrusions (3), it is ensured that a flexible ventilation duct (2) which is fastened rigidly by penetrating through itself is fixed on a connection point. As shown in
As can be understood more easily from
The practical connecting apparatus (1) which is the subject of the invention fastens the flexible ventilation duct (2) to the main ventilation duct rigidly with the screws to be penetrated through the said mounting holes (4). The mounting protrusions (3) generated around the said apparatus (1), besides eliminating the requirement for plastic clamps and tapes used in the previous technique, pave the way for a more resistant and long-lasting installation by enabling a screw mounting by means of the mounting holes (4) it has.
Claims
1. The invention is a connecting apparatus (1) which practically fixes the flexible ventilation ducts (2) to a main ventilation area or to a connection point without any need for a plastic clamp or tapes, and its feature is that it is characterized by the fact that the said flexible ventilation duct (2) contains one fastening ring (5) by which it fastens tightly by encircling from an end, and at least one mounting protrusion (3) located towards the exterior of the said fastening ring perpendicular to the center of the said duct, and at least one mounting hole (4) for fixing the said flexible ventilation duct (2) fastened by the said mounting protrusion (3) to a main duct with a connection means such as a screw.
2. It is a connecting apparatus (1) according to the claim 1, and its feature is that; it is characterized by the fact that the said apparatus serves as a natural gasket between the said apparatus (1) and said flexible ventilation duct (2) and the main duct or the connection point which it is intended to be penetrated through.
3. The invention is a connecting apparatus (1) which practically fixes the flexible ventilation ducts (2) to a main ventilation area or to a connection point without any need for a plastic clamp or tapes, and its feature is that it is characterized by the fact that the said ventilation duct (2) has at least one mounting protrusion (3) which it fastens tightly by encircling from an end, and that the ventilation duct which is fastened by the said mounting protrusion (3) is connected to a main duct by being screwed through the said mounting protrusion (3).
