Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a gutter drain, particularly to a gutter drain used to connect a rectangular vertical gutter to a rectangular eaves gutter.

[Conventional technology]

Conventionally, this type of gutter drain has been attached to a flange provided on the outer circumferential surface of the upper end of a cylindrical inner and outer drain cylinder formed by forming threads on the circumferential body that are screwed into each other by rotation. Generally, the rim of the opening in the bottom of the eaves gutter can be clamped, but since it is fixed by rotation,
Since the above-mentioned drainage cylinder is cylindrical, an odd-shaped elbow (rounded corner elbow) is required when connecting a rectangular downpipe, and as a result, the cross-sectional area of the drainage pipe becomes small, impeding drainage performance. Instead of burrs, there is a difference in level between the joints, which inevitably causes problems such as a deterioration in aesthetics.

[Problem that the invention attempts to solve]

This invention was devised to eliminate the drawbacks of the conventional products described above, and aims to provide a gutter drain that can connect a rectangular vertical gutter to a rectangular eave gutter without using the irregularly shaped elbow described above. .

[Means to solve the problem]

This invention was devised in view of the above, and includes forming a flange on the outer periphery of the upper end of the rectangular drain tube, and attaching a locking ring via a support piece to the approximate center of the lower end opening of the rectangular drain tube. a connecting tube provided with a frame plate having substantially the same shape as the flange, and an upper end that fits loosely into the locking ring when the frame plate is brought into contact with the flange and has a thread on the outer circumferential surface; A holding tool having an engaging tool having a flange piece on its outer circumferential surface protruding through a support piece, and a screw on its inner circumferential surface that is screwed into the thread of the engaging tool,
The problem was solved by using a stopper that presses the locking ring toward the flange piece by screwing as described above.

〔Example〕

Hereinafter, an embodiment of this invention shown in the drawings will be described. FIG. 1 is an exploded perspective view showing an embodiment of this invention. A flange 2 is formed on the periphery of the rectangular drain tube 1, and four supporting pieces 3 are provided approximately in the center of the lower end opening of the rectangular drain tube 1 to protrude from the corners of the rectangular drain tube 1 toward the center. A locking ring 4 is provided, and B is a presser, which is a frame plate 5 having substantially the same shape as the flange 2, and four pieces having elasticity hanging from each side of the frame plate 5. An engaging tool 9 having a thread 7 on the outer circumferential surface and a collar piece 8 on the upper end outer circumferential surface is provided protruding downward from the opening through the support piece 6 of the above-mentioned engaging tool. 9 is a frame plate 5 on the flange part 2
It is formed so as to fit loosely into the locking ring 4 when the locking ring 4 is brought into contact with the locking ring 4, and C is a stopper which is screwed into the thread 7 of the locking member 9 on the inner circumferential surface. It has a screw 10 and is formed so that the locking ring 4 can be pressed toward the collar piece 8 by the screwing. Since this device has the above-mentioned configuration, when in use, as shown in FIG. Frame plate 5 of presser B
to make the engaging tool 9 protrude downward from the opening of the eaves gutter a, and then the flange 2 of the connecting tube A is brought into contact with the lower surface of the opening periphery b, and is loosely fitted onto the engaging tool 9. The stopper C is fitted from below the locking ring 4 positioned so that the screw 10 is inserted into the thread 7 of the engaging member 9.
By screwing the retaining ring 4 toward the flange piece 8 using the stopper C, the elastic force of the support piece 6 tightens the flange part 2 and the frame plate 5, thereby opening the eaves gutter a. The circumferential edge b is clamped and fixed, and the vertical gutter c is connected to the rectangular drain pipe 1.

[Effect of idea]

As is clear from the above, in the gutter drain of this invention, the screw 10 of the stopper C is screwed into the thread 7 of the engagement member 9 via the locking ring 4, so that the flange portion 2
Also, since the frame plate 5 clamps and fixes the opening periphery b of the eaves gutter a, and the rectangular drain pipe 1 is directly formed on the opening periphery b of the eaves gutter a, it is different from that seen in conventional products. There is no reduction in the drainage cross-sectional area or the formation of steps due to the use of odd-shaped elbows, and this further improves drainage performance and aesthetics.Furthermore, the support piece 3 and the support piece 6 can be used together as a leaf protection, etc. It also has features not found in other products.
