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, a type that can be clamped around the periphery of an opening formed in the bottom of the eaves gutter is used.

[The problem that the idea attempts to solve]

However, since the gutter drain is fixed by rotation, the drain cylinder body is cylindrical, so when connecting rectangular vertical gutter, an irregular elbow (rounded corner elbow) is required, and as a result, The small cross-sectional area of the drain tube not only impedes drainage performance, but also has negative effects such as deterioration of aesthetics due to the presence of steps at the connecting portions.

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 idea 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 an L-shaped notch at the upper end via a support piece above the opening of the rectangular drain tube. A connecting cylinder having an engaging groove formed in the shape of the flange and an engaging tool having a flange piece protruding from the outer periphery of the lower end; a holding tool having a locking ring protruding through a support piece so as to loosely fit on the above-mentioned engaging tool when the holding tool comes in contact with the above-mentioned engaging tool; This gutter drain has an engaging protrusion that engages with the engagement groove of the drain, and a stop that presses the locking ring toward the collar piece by engagement of the engaging protrusion.

〔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, and four supporting pieces 4 are raised from each side of the rectangular drain tube 1 approximately at the center above the opening 3 of the rectangular drain tube 1.
A ring-shaped engagement tool 7 having an L-shaped engagement groove 5 cut out at the upper end and a collar piece 6 at the outer periphery of the lower end is protruded through the ring, and B is a presser foot. It is a tool that locks into an opening 9 of a frame plate 8 having substantially the same shape as the flange 2 through four elastic support pieces 10 raised from each corner of the frame plate 8. A ring 11 is provided in a protruding manner, and the locking ring 11 loosely fits into the engagement tool 7 and locks onto the collar piece 6 when the frame plate 8 is brought into contact with the collar portion 2. C is a stopper, and an engaging protrusion 12 is fitted on the inner circumferential surface of the engaging member 7 and engages with the engaging groove 5 of the engaging member 7. It is formed so that the locking ring 11 can be pressed toward the collar piece 6 by the engagement described above.

Since this device has the above-mentioned configuration, when in use, as shown in FIG. The flange 2 of the connecting tube A is brought into contact with the flange 2 of the connecting tube A to project the engaging tool 7 upward from the opening 3, and then the presser tool B is placed on the upper surface of the opening periphery b.
The stopper C is fitted from above the locking ring 11 which is positioned so as to fit loosely on the engaging tool 7, and is engaged with the engaging groove 5 of the engaging tool 7. Projection piece 1
2 and press the locking ring 11 toward the flange piece 6 with the stopper C, the elastic force of the support piece 10 tightens the flange part 2 and the frame plate 7, opening the eaves gutter a. The circumferential edge b of the drain pipe 1 is clamped and fixed, and a vertical pipe c is connected to the rectangular drain pipe 1.

[Effect of idea]

As is clear from the above, the gutter drain of this invention is engaged by inserting the projecting piece 12 of the stopper C into the engagement groove 5 of the engagement member 7 through the engagement ring 11 and rotating it. The opening periphery b of the eaves gutter a is clamped and fixed between the flange 2 and the frame plate 8, and the rectangular drain pipe 1 is directly formed on the opening periphery b of the eaves gutter a. Moreover, since there is no reduction in the drainage cross-sectional area or formation of steps that are caused by the use of irregularly shaped elbows as seen in conventional products, drainage performance and aesthetics are further improved.
