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. State of Art Analysis Document MU 7502586 presents a gas tubing coupling and its respective terminal, which differs from the present invention for not mentioning double coupling clamps and not ensuring the gas tubing alignment. Document WO 01/38771 Al describes a transition element between two plug-in type line systems and does not mention, at any time, double coupling clamps, differing, then, from the present invention. Document MU 7701371 describes a constructive arrangement for the entry connection of stove gas that comprises two pipe-shaped bodies, not conflicting at all with the provisions of the present invention. Document MU 7701372 7U describes an easel type extension regulator body in which a clamp is observed, however not advancing the same innovative aspects of the present invention. Description of Figures Figure 1 presents an approach in four views of the proposed system, applied to the gas regulator (2). Figure IA shows a sidelong view of the set, where it is observed the gas tube fastening (1) in the regulator (2) through the clamp (4), using the double coupling in the side projections (5). Figure IB illustrates the rear view of the set, allowing viewing the "U" curve (4a) of the clamp (4) and the side projections (5) that receive the clamp fitting (4). Figure 1C shows an upper view of the set, pointing out the gas tube (1) fastening with the clamp (4), using the side projection (5) of the regulator (2). Figure ID shows a cut-way view of the set, representing the gas tube (1) fastening by the clamp (4) to the regulator body (2). Figure 2 presents an approach in four views of the proposed system, applied to the table venturi (3). Figure 2A shows an upper view of the set, pointing out the gas tube (1) fastening with the clamp (4), using the side projections (5) of the venturi (3). Figure 2B shows a side view of the set, where it can be observed the gas tube (1) fastening in the venturi (3) through the clamp (4), using the double coupling in the side projections (5). Figure 2C shows a cut-way view of the set, representing the gas tube (1) fastening through the clamp (4) to the venturi body (3). Figure 2D illustrates a rear view of the set, allowing viewing the "U" curve (4a) of the clamp (4) and the side projections (5) that receive the clamp fitting (4). 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.
