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 structure in which the periphery of a circular opening at the bottom of the eaves gutter can be clamped is used, but since it is fixed by rotation, the drain cylinder body is formed into a cylindrical shape. Therefore, when connecting rectangular vertical troughs, an irregularly shaped elbow (rounded elbow) is required, and as a result, a step is created at the connecting portion, resulting in negative effects such as a decrease in aesthetics.

[Problem that the invention attempts to solve]

This invention was devised to eliminate the drawbacks of the conventional products described above, and is a gutter drain that can connect a rectangular vertical gutter to a rectangular eave gutter without using the irregular elbow described above. It is an object of the present invention to provide a gutter drain that can connect a rectangular vertical gutter to a circular opening that is relatively easy to open.

[Means for solving problems]

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 outer circumferential surface of the rectangular drain tube via a support piece above the opening. , a connecting tube formed by protruding an engagement tool having a flange piece on the outer peripheral surface of the lower end, a circular frame plate having a diameter substantially the same as the long side of the flange, and a frame plate facing the flange. The holding tool has a locking ring protruding through a support piece so as to loosely fit onto the engaging tool, and a screw on the inner circumferential surface that is screwed into the thread of the engaging tool. This is a gutter drain consisting of a stopper which presses the locking ring downward by the above-mentioned screwing.

〔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.
A ring-shaped engagement tool 7 having a thread 5 on the outer peripheral surface and a collar piece 6 on the outer peripheral surface of the lower end thereof is provided protrudingly through the ring, and B is a holding tool; The locking ring 11 is inserted onto the opening 9 of a circular frame plate 8 having a diameter substantially the same as the long side of the flange 2 through four pieces of elastic support pieces 10 raised from the frame plate 8. The locking ring 11 engages the engagement tool 6 when the frame plate 8 is brought into contact with the flange 2.
It is formed so as to fit loosely into C.
is a stopper, and the above-mentioned locking ring 11 is attached to the outer peripheral surface.
It has a screw 12 that is screwed into the thread 5 of the engagement tool 7 through the screw 12, and is formed so that the locking ring 11 can be pressed toward the collar piece 6 by the screwing.

Since this device has the above-mentioned configuration, when in use, as shown in FIG. The collar part 2 of the connecting tube A is brought into contact with the lower surface of the peripheral edge b, and the engaging tool 7 is projected upward from the opening 3, and then the frame of the presser tool B, which is circular in shape, is placed on the upper surface of the opening peripheral edge b. Abutting the plate 8 and fitting the stopper C from above the locking ring 11 which is positioned so as to loosely fit onto the engagement tool 7, and screwing the screw 12 into the thread 5 of the engagement tool 7. Then, by pressing 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 8, and the opening periphery b of the eaves gutter a is tightened. Clamp and fix the
A vertical gutter c is connected to a rectangular drain pipe 1.

[Effect of idea]

As is clear from the above, in the gutter drain of this invention, the threaded thread 5 of the engaging tool 7 is inserted through the locking ring 11.
By screwing the screw 12 of the stopper C into the rim 2, the square flange 2 and the circular frame plate 8 clamp and fix the opening periphery b of the eaves gutter a. Since the rectangular drain tube 1 is directly formed on B, there is no reduction in the drainage cross-sectional area or formation of steps that would occur with the use of irregularly shaped elbows as seen in conventional products, and this further improves drainage performance and aesthetics. Furthermore, it has features such as easy construction because it is possible to create a circular opening.
