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 hard 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 tube body is cylindrical, an odd-shaped elbow (rounded corner elbow) is required when connecting a rectangular hard trough, and as a result, the cross-sectional area of the drain tube becomes small, impeding drainage performance. Not only this, but also the presence of steps at the connecting portions has unavoidable negative effects such as deterioration of 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 rigid 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 a flange formed on the outer periphery of the upper end of the rectangular drain tube, and a threaded connection on the outer circumferential surface of the rectangular drain tube via a support piece over the opening of the rectangular drain tube. A connecting tube having a fitting protruding thereon and a frame plate having substantially the same shape as the flange are provided with support pieces interposed therebetween so as to fit loosely into the engaging fitting when the frame plate is brought into contact with the flange. a retaining tool having a locking ring protruding therefrom; and a screw having an inner circumferential surface that is screwed onto the thread of the engaging tool, and is loosely fitted into the engaging tool by screwing the screw into the thread. The problem was solved by using a stopper that presses the locking ring downward.

〔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 6 with a thread 5 provided on the outer circumferential surface is protruded through the frame plate B, which is a holding tool and has a frame plate having substantially the same shape as the flange 2. A locking ring 10 is protruded from the opening 8 of the frame plate 7 through four pieces of elastic support pieces 9 raised from each corner of the frame plate 7. It is formed so as to loosely fit into the engaging tool 6 when the frame plate 7 is brought into contact with the flange 2, and C is a stopper, and the engaging tool 6 is attached to the inner circumferential surface.
The locking ring 10 loosely fitted onto the engagement tool 6 can be pressed downward from above by screwing the screw 11 into the thread 5. It is formed in

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 6 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 10 which is positioned so as to fit loosely on the engagement tool 6, and the screw 11 is inserted into the thread 5 of the engagement tool 6. By screwing the locking ring 10 downward with the stopper C, the elastic force of the support piece 9 tightens the collar 2 and the frame plate 7, and the opening periphery b of the eaves gutter a is tightened. The rigid gutter c is connected to the rectangular drain pipe 1 by clamping and fixing it.

Incidentally, the engaging member 6 and the stopper C of the connecting tube A may be formed in the shape of a bolt or a nut as shown in FIG. 3.

[Effect of idea]

As is clear from the above, in the gutter drain of this invention, the threaded thread 5 of the engagement tool 6 is inserted through the locking ring 10.
By screwing the screw 11 of the stopper C into the flange 2 and the frame plate 7, the opening periphery b of the eaves gutter a is clamped and fixed, and the rectangular drain pipe 1 is attached to the opening periphery b of the eaves gutter a. Since it is directly formed, 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, and this further improves drainage performance and aesthetics.
