Description

[Detailed description of the invention] (Field to which the technology belongs) The present invention is a gutter elbow that allows rainwater to flow smoothly from the gutter to the eaves gutter, and has improved workability.

(Prior art and its problems) In the conventional gutter elbow, the connecting short pipe to the gutter and the bent pipe are integrated, and the connecting short pipe and the bent pipe can be attached and detached. Since it does not rotate in the circumferential direction, it is specified as being exclusively used for square gutter or round gutter.

In addition, since it is an L-shaped fixed type during construction,
If you misjudge the water gradient of the eaves gutter, you will have to re-glue and fix it to the eaves gutter, which is troublesome.

(Means for Solving the Problems) The present invention solves the above problems, and the gist thereof is to provide a connecting short pipe 1 that connects to a gutter at one opening, and a connecting short pipe 1 that connects to a gutter at one opening. It is a gutter elbow consisting of a curved pipe 2 having an engagement convex portion that engages with an engagement groove provided on the outer periphery of the other opening of the gutter elbow. Above the angle, it is a gutter elbow with a mechanism to prevent rotation.

Hereinafter, the specific configuration of the present invention will be explained with reference to the drawings.

FIG. 1 shows an exploded perspective view of an embodiment of the present invention, and FIG. 2 shows a perspective view of the installed state of the product of the present invention.

As shown in Figure 2, this invention is a type of elbow used to allow rainwater to flow smoothly from the gutter 6 to the eaves gutter 7, and as shown in Figure 1, one opening is connected to the lower end of the gutter. Connecting short pipe 1 to accept and connect
and a curved tube 2 having an engagement convex portion 4 that engages with an engagement groove 3 provided on the outer periphery of the other opening of the short connecting tube 1.
By engaging the engagement convex portion 4 with the engagement groove 3, the connecting short pipe 1 and the bent pipe 2 can be rotated by a predetermined angle in the circumferential direction of the axis of the connecting short pipe 1. Concatenated.

The features of the gutter elbow of this invention are as follows:
It is set so that it can rotate by a predetermined angle θ between the curved tube 2 and the curved tube 2, as shown in FIG. The predetermined angle θ
is necessary to prevent rainwater from overflowing from the eaves gutter due to the bent pipe 2 jumping up due to the force of the flowing water from the eaves gutter 6. The angle is preferably around 45°.

In order to prevent the bending pipe 2 from jumping up, a stopper 8 is formed in the engagement groove 3 provided on the outer periphery of the other opening of the connecting short pipe 1, as shown in FIG. The engaging protrusion 4 of the curved tube 2 that engages with the groove 3 is provided with a mechanism for preventing rotation of the curved tube 2 by the stopper 8 so that the curved tube 2 does not rotate beyond a predetermined angle.

Both the rotatable engagement groove 3 and the engagement protrusion 4 have an annular cross section.

One opening of the short connecting pipe has a shape that can be fitted in accordance with the cross-sectional shape (square, round) of the gutter, and the other opening engages with the curved pipe 2 to connect it detachably. be done.

In addition, one opening of the connecting short pipe has a double structure, and the outside thereof forms a square wall that receives and connects the square gutter as shown in the figure, and although not shown, the inside of the square wall By forming a round wall that is inserted into and connected to the round gutter, it is also possible to create a gutter elbow that also serves as a rounded corner.

Further, the discharge port 5 of the present invention is preferably formed with a tapered notch at the lower end of the curved pipe 2, as shown in the figure, so that rainwater can be smoothly discharged.

(Effects of the invention) Since the invention has the above configuration, it has the following effects.

(1) The force of rainwater from the gutter allows rainwater to flow smoothly from the eaves gutter without overflowing.

(2) Depending on the angle and round shape of the gutter, the connecting short pipe can be replaced (i.e., the bent pipe is shared), or if the connecting short pipe has a double structure as described above,
Since one connecting short pipe can be applied to both square and round gutters, there is no need to prepare gutter elbows exclusively for square or round gutters as in the past.

(3) Even if you misjudge the water gradient of the eaves gutter and glue the connecting short pipe to the gutter during construction, all you have to do is rotate or remove the bent pipe and reattach it at the specified angle. There is no need to redo construction.
