Description
FASTENING SYSTEM FOR GAS TUBES IN STOVES
Field of the invention
This invention refers to a fastening system for gas tubes in the regulator or venturi of the gas stoves table, comprising of a clamp with double coupling whose center part envelops the tube end which penetrates into the gas regulator or venture, allowing the coupling in two sidelong projections foreseen in the regulator or venturi body. Then, with a double coupling, the gas tube is aligned with the element to which it is connected. Background of the invention Currently, in the state of the technique, the connection between the gas tube and the regulator is commonly made with the use of elements with screw, which requires accessories such as washers and chemical seals to avoid gas leakages in these joints. This system tends to endear the final product, considering both the components cost and the employed manpower. In other also known alternative, a plate strap is used to fasten the tube into the regulator. In this case, the strap used to fix the tube into the regulator has a risky coupling, which allows the tube to move sidelong and, therefore, is likely to have a gas leakage in this connection. In another similar fastening, instead of using a metallic plate strap, it is used a wire strap with coupling only in one side of the regulator. In this case, the same problem with the plate strap occurs, i.e., sidelong misalignment between the tube and the regulator, which may provoke a gas leakage in the connection. The invention purpose is to simplify and, at the same time, improve the connection between the tube and the regulator in order to avoid the drawbacks pointed in the state of the technique through a fastening system, which ensures the tubing alignment and minimize the likelihood of leakage incidents.

Detailed Description of the embodiment
This invention describes a connection system to be used in gas stoves gas tubes (1) fastening, providing both a firm connection and the alignment of the elements involved. The system promotes the integration between the gas tube (1) with the stove regulator (2) or with the stove table venturi (3), using a double coupling clamp (4), and its center part (4a) envelops the tube end (1) which penetrates into the regulator (2) or into the venturi (3), whose ends engage in two side projections (5) foreseen in the regulator (2) or venturi (3) body. With the double coupling, the gas tube (1) remains aligned with the regulator (2) or venturi (3), depending on the application, minimizing the likelihood of a gas leakage, and also incurring a smaller cost, more speed and simplification in the set assembly process.
The fastener clamp (4) of the gas tube (1) presents, on its core, a U-shaped curvature (4a) which envelops the tube (1) behind the tube (1) circular expansion. The two ends of the fastener clamp (4) of the tube (1) are projected and bent to the sides of the regulator (2) or venturi (3) cylindrical body, bending ahead once again and partially enveloping the two side projections (5) of the regulator (2) or venturi (3) cylindrical body. The clamp (4), so assembled, arranges the tube fastening in the regulator (2) or venturi (3), preventing these from naturally separating, since the circular expansion of the gas tube (1) has a greater diameter than the U portion (4a) of the clamp (4), and also such expansion stays inside the regulator (2) or venturi (3) end, where the sealing ring is lodged. This invention is not limited to the representations mentioned or illustrated
herein, and it has to be comprehended in its wide scope. Many changes and other representations of the invention will come in mind of those skilled in the technique to which this invention belongs, having the learning benefit presented in previous descriptions and attached drawings. Further, it is to be understood that the invention is not limited to the disclosed specific shape and that changes and other shapes are understood as enclosed within the scope of the attached claims. Although specific terms are nominated herein, they are only used in a generic and descriptive form and not for a limiting purpose.
