Description

[Detailed description of the invention] [Industrial application field] This invention relates to an elliptical pipe that is mainly used as a cap for balconies of buildings, window handrails, etc.

[Conventional technology]

Conventionally, metal caps used for building balconies, window handrails, etc. have square or square cross sections. This is because with circular pipes, it is difficult to connect and fix the grid by welding or the like.

[Problem that the invention aims to solve] However, from an aesthetic point of view, depending on the place where it is used, a product with a rounded and soft feel is required, and furthermore, it is difficult to deform when external force is applied. is required.

This invention was made as a technical challenge to meet such demands.

[Means for solving problems]

The means for solving the above technical problem is to connect the upper and lower ends of two circular pipes arranged in parallel with a predetermined distance and formed in a straight or curved shape to the two circular pipes. The pipes are connected and fixed in the longitudinal direction by a connecting plate whose width is slightly longer than the distance between the opposing outer peripheral surfaces of the pipes.

[Effect]

According to the elliptical pipe of the above-mentioned means, since the connecting plate at the bottom has a planar shape, the grid can be easily fixed by welding. This reduces work costs and improves work efficiency. In addition, because the cross-sectional shape is oval, it can give a soft feel to the appearance.
It is particularly suitable for residential buildings where people live. Furthermore, since the upper and lower ends of the two circular pipes are connected and fixed by a connecting plate, they are not easily deformed by external forces.

〔Example〕

An embodiment of this invention will be described below based on the drawings.

The elliptical pipe 1 of this embodiment is shown in FIGS.
As shown in the figure, connecting plates 3 are connected and fixed to the upper and lower ends of two circular pipes 2 arranged in parallel, respectively, by welding or the like.

The shape of the two circular pipes 2 may be linear or curved. These can be easily bent into any shape using mechanical tools. Further, the distance between the two circular pipes 2 is not particularly limited, and is appropriately selected depending on the intended use.

The shape of the upper and lower connecting plates 3 has a width slightly longer than the distance between the opposing outer peripheral surfaces of these two circular pipes 2, and the length in the longitudinal direction is the same as that of the circular pipes 2.
The length is approximately equal to the length of .

In order to connect and fix such two circular pipes 2 and the connecting plate 3, the upper ends of the two circular pipes 2 and both ends of one connecting plate 3 are connected and fixed by welding or the like, and the lower end of the same It is only necessary to connect and fix the part and both ends of the other connecting plate 3 by welding or the like. When the parts are connected and fixed by welding, from the viewpoint of aesthetics, the uneven parts are ground down with a grinder or the like to make them flat.

The most preferable material for the circular pipe 2 and the connecting plate 3 is stainless steel, which does not cause rust.

Next, an example of use of such an elliptical pipe 1 as a handrail B of a balcony A will be described based on FIG. 3.

First, the elliptical pipe 1 is formed in advance to match the shape of the outer peripheral end of the balcony A to be attached. Then, the upper ends of the lattice C are connected and fixed at equal intervals to approximately the center of the connecting plate 3 below the elliptical pipe 1 by welding or the like. Next, the lower end of the lattice C is connected and fixed to the upper surface of the decorative beam D, which is formed to have substantially the same shape as the connecting plate 2, by welding or the like. This forms a handrail B. To attach this handrail B to the balcony A, the decorative beam D is connected and fixed along the outer peripheral edge of the balcony A with bolts or the like (not shown).

[Effect of idea]

As is clear from the above explanation, according to this invention, it is possible to form the handrails of balconies etc. into a rounded shape, which was impossible with the conventional technology, so that it can be used in buildings such as houses. It has the advantage of providing aesthetically pleasing results when used on balconies and window rails. Further, since the grid can be attached by welding, there is an advantage that the work cost can be reduced and the workability can be improved.

[Brief explanation of drawings]

The drawings show an example of this invention; Fig. 1 is a partially sectional perspective view, Fig. 2 is an enlarged sectional view with the - line partially omitted in Fig. 3, and Fig. 3 is a handrail of a building balcony. An example usage diagram is shown below. 1...Oval pipe, 2...Circular pipe, 3...
