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. Not only that, but the presence of a level difference in the connecting portion has unavoidable negative effects such as a deterioration in aesthetic appearance.

[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 vertical gutter without using the irregularly shaped elbow described above. .

[Means to solve the problem]

This device was devised in view of the above, and includes a flange formed on the outer periphery of the upper end of the rectangular drain tube, and a thread provided on the inner circumferential surface of the rectangular drain tube via a support piece above the opening. A connecting cylinder having an engaging ring protruding therefrom and a frame plate having substantially the same shape as the flange are positioned at a predetermined distance above the engaging ring when the frame plate is brought into contact with the flange. As shown in FIG. The problem was solved by using a stopper formed of a pressing collar that presses the locking ring.

〔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 at approximately the center above the opening 3 of the rectangular drain tube 1.
An engagement ring 6 having a thread 5 is protruded from the inner circumferential surface of the engagement ring 6 through which B is a presser;
A locking ring 1 is inserted into an opening 8 of a frame plate 7 having substantially the same shape as the flange 2 through four elastic support pieces 9 raised from each corner of the frame plate 7.
0 is provided protrudingly, and the locking ring 10 is formed so as to be positioned above the engagement ring 6 at a predetermined interval when the frame plate 7 is brought into contact with the collar portion 2. C is a stopper, which has a screw 11 on its outer circumferential surface that is screwed into the thread 5 of the engagement ring 6 via the above-mentioned locking ring 10, and the locking ring on the outer peripheral edge of the upper end. 10 is formed with a pressing collar 12 that presses it from 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 opening 3 to cause the engagement ring 6 to protrude upward from the opening 3, and then the frame plate 7 of the presser B is brought into contact with the upper surface of the opening periphery b to engage A stopper C is inserted from above the locking ring 10 positioned on the ring 6 at a predetermined interval, and the screw thread 5 of the engagement ring 6 is inserted.
By screwing the screw 11 into the and tightening the engagement ring 6 and the locking ring 10 with the pressing flange 12, the elastic force of the support piece 9 tightens the flange 2 and the frame plate 7, and the eaves gutter a The peripheral edge b of the opening 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 11 of the stopper C is screwed into the thread 5 of the engagement ring 6 via the locking ring 10, thereby attaching the flange 2 and the frame plate 7. Since the peripheral edge b of the opening of the eaves gutter a is clamped and fixed, and the rectangular drainage tube 1 is directly formed on the peripheral edge b of the opening of the eaves gutter a, it is not possible to use an irregularly shaped elbow like that seen in conventional products. There is no accompanying reduction in the drainage cross-sectional area or formation of steps, and the drainage performance and aesthetics are further improved.
