Description

[Detailed description of the invention] [Industrial field of application] This invention is a gutter drain used to connect an eaves gutter and a vertical gutter, particularly for connecting a rectangular vertical gutter to a rectangular eave gutter. This relates to the gutter drain provided.

[Conventional technology]

Conventionally, this type of gutter drain has been installed using a flange provided on the outer circumferential surface of the upper end of a cylindrical inner and outer drain cylinder, which is formed by forming threads on the circumferential body that are screwed into each other by rotation. Generally, a type of eaves gutter that can be clamped around the periphery of an opening formed on the bottom of the eaves gutter is used, but since the drainage cylinder is cylindrical, it is difficult to requires joining an irregularly shaped elbow (rounded elbow) to the drainage tube, and as a result, the effective drainage areas of the drainage tube and the irregularly shaped elbow are different, which not only reduces drainage performance, but also reduces workability. However, it could not be said to be desirable in terms of aesthetics or economy.

(Problems to be Solved by the Invention) This invention was devised to eliminate the drawbacks of the conventional products described above, and is a gutter that can connect a rectangular vertical gutter to a rectangular eave gutter without using the irregularly shaped elbow described above. It is intended to provide a drain for use.

[Means to solve the problem]

This invention was devised in view of the above, and includes a dust guard formed in the central opening of a rectangular frame plate, and a presser plate formed by suspending screw rods from the inner periphery of the opposing sides of the frame plate. A flange that contacts the frame plate is formed on the outer peripheral edge of the upper end of the rectangular drain tube, and a locking piece having an insertion hole through which the screw rod is inserted is provided protruding from the opposing inner wall surface of the rectangular drain tube. The problem was solved by using a connecting tube made of a metal tube and a nut screwed onto the screw rod.

〔Example〕

Hereinafter, an embodiment of this invention shown in the drawings will be described. FIG. 1 is a perspective view showing an embodiment of this invention. A dust guard 2 is formed in the opening, and a screw rod 3 is provided on the inner peripheral edge side of the opposite side of the frame plate 1.
B is a connecting tube, and the frame plate 1 is attached to the outer periphery of the upper end of the rectangular drain tube 4.
A locking piece 7 is formed on the opposing inner wall surface of the rectangular drain pipe 4 and has a through hole 6 through which the screw rod 3 is inserted, and C is a locking piece 7. The peripheral edge c of the opening b of the eaves gutter a interposed between the frame plate 1 and the flange 5 is screwed onto the screw rod 3 inserted through the insertion hole 6 of the stopper 7. 5 shows a nut for clamping and fixing.

Note that it is preferable to use a plate body having an L-shaped cross section with a vertical plate 8 along its inner peripheral edge as the frame plate 1 from the viewpoint of workability.

Since this device has the above-mentioned configuration, when in use, as shown in FIG. The screw rod 3 and the vertical plate 8 of the plate A are inserted from above, and the frame plate 1 is brought into contact with the periphery c of the opening b, and then the flange 5 of the connecting tube B is placed on the lower surface of the frame plate 1.
is abutted from below, and the insertion hole 6 of the locking piece 7 is fitted into the threaded rod 3 protruding downward from the opening b, and the frame plate 1 and the flange 5 are connected to the opening b of the eaves gutter a.
The peripheral edge c of the screw rod 3 is clamped, and then a nut C is screwed onto the screw rod 3 and tightened and fixed.

[Effect of idea]

As is clear from the above, in the gutter drain of this invention, the rectangular drain pipe 1 is formed directly on the eaves gutter a by screwing the nut C into the screw rod 3 inserted into the insertion hole 6 of the locking piece 7. There is no deterioration in drainage performance, workability, aesthetics, or economic efficiency associated with the use of irregularly shaped elbows as seen in conventional products.
and a locking piece 7 is formed on the inner periphery of the frame plate 1 and the rectangular drain pipe 4, so that the frame plate 1 and the flange 5 can clamp the opening periphery c of the eaves gutter a. It is.
