Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a drain for an eaves gutter that is attached to the eaves gutter and drains water from the eaves gutter when draining water from the eaves gutter to a vertical gutter or chain gutter.

[Background Art] A conventional eaves gutter drain A' consists of an upper cylinder 1' and a lower cylinder 2' as shown in Fig. 3, and a male threaded part 3' is provided on the outer periphery of the upper cylinder 1'. A flange 4' is provided at the upper end of the cylindrical body 1', and a female threaded part 5' is provided on the inner periphery of the lower cylindrical body 2'.
It was formed by providing a flange 6' at the upper end of the lower cylinder body 2'. When installing eaves gutter drain A' to eaves gutter B, open the opening 7 at the bottom of eave gutter B.
The flange 6' of the lower cylindrical body 2' is brought into contact with the lower surface of the bottom of the eaves gutter B, the upper cylindrical body 1' is inserted into the opening 7, and the male threaded part 3' is screwed into the female threaded part 5'. Connect flange 4' to eaves gutter B
The bottom of the eaves gutter B was held between the brim portions 4' and 5'. A basket-shaped dust guard 8' was attached to the flange 4'. In such a conventional example, a drain for an eave gutter consists of an upper cylinder 1' and a lower cylinder 2'.
It is necessary to install the garbage guard 8' separately after installing A', which requires a lot of work, and also requires two parts: the drain A' for the eaves gutter and the garbage guard 8', which reduces the number of parts. The disadvantage is that there are many.

[Purpose of the invention] The present invention was made in view of the points mentioned above, and the purpose of the invention is to provide a drain for eaves gutters that can be easily installed with a dust guard and can be constructed with a small number of parts. is to provide.

[Disclosure of the invention] The drain A for eaves gutters according to the present invention has a flange 6 around the upper part of the lower cylindrical body 2 that comes into contact with the lower surface of the bottom of the eaves gutters B, and a lower surface is provided in the opening 7 at the bottom of the eaves gutters B. The male threaded cylinder 5 inserted from the side and positioned in the eaves gutter B and the lower cylinder body 2 are integrally formed via a plurality of support pieces 9, and the male threaded cylinder 5 is attached to the inner periphery of the upper cylinder body 1. A female screw part 3 is provided on the outer periphery, and a plurality of dust prevention pieces 8 are integrally extended from the bottom of the upper cylinder body 1, and the ring body 4 that comes into contact with the upper surface of the bottom of the eaves gutter B is dust-proof. It is provided integrally with the guard piece 8, and by configuring it as described above, the drawbacks of the conventional example are solved. In other words, the upper cylinder 1 and the lower cylinder 2 are arranged above and below the bottom of the eaves gutter B, and the male threaded cylinder 5 is inserted from the opening 7 of the eaves gutter B into the eaves gutter B.
the male threaded tube 5 and the female threaded portion 3 of the upper tube body 1.
By screwing them together, a drain can be formed, and at the same time, a dust guard part can be formed with the dust guard piece 8, and the construction is simpler than before, and the number of parts is reduced. This makes it possible to improve workability.

The present invention will be explained in detail below with reference to Examples.

As shown in Fig. 1, the eaves gutter drain A is mainly composed of a cylindrical upper cylinder 1 and a lower cylinder 2, and the upper cylinder 1 and the lower cylinder 2 are each made of synthetic resin. has been done. A cylindrical collar part 6 is provided at the upper part of the lower cylinder body 2.
A plurality of support pieces 9 are integrally provided around the flange 6, and a plurality of supporting pieces 9 are integrally provided upwardly from the inner peripheral side of the flange 6.
A male threaded tube 5 having a male threaded portion 5a on the outer periphery is integrally provided at the upper end of the support piece 9. A female thread 3 is provided on the inner periphery of the upper cylinder 2, and a plurality of dust prevention pieces 8 are integrally provided in a radial manner projecting obliquely downward from the upper cylinder 2. An annular ring 4 is integrally provided at the lower end of the ring 8. The eaves gutter drain A constructed as described above is attached to the eaves gutter B in the following manner. A circular opening 7 is formed at the bottom of the eaves gutter B, the lower cylinder 2 is arranged below the opening 7, the upper cylinder 1 is arranged above the opening 7, and the externally threaded cylinder 5 of the lower cylinder 2 is arranged. and the support piece 9 are inserted into the opening 7, the female threaded part 3 of the upper cylinder body 1 is screwed into the male threaded cylinder 5, and the eaves gutter B is inserted between the ring body 4 and the collar part 6 as shown in FIG. Clamp the bottom. Drain A for eaves gutter is attached to eave gutter B as described above, and drain A for eave gutter
A vertical pipe, a chain pipe, etc. are connected to the lower cylinder body 2. Therefore, water is drained from the eaves gutter B through the eave gutter drain A to the vertical gutter or chain gutter. Further, when the wastewater flows from the eaves gutter B to the eaves gutter drain A, the garbage is caught on the garbage prevention piece 8 and the support piece 9, and the garbage is prevented.

[Effect of the invention] Since the present invention is constructed as described above, the upper cylinder and the lower cylinder are arranged above and below the opening provided in the eaves gutter, and the male threaded cylinder of the lower cylinder is connected together with the support piece. By inserting it into the opening and screwing the female threaded part of the upper cylinder into the male threaded cylinder, the bottom of the eaves gutter is held between the collar part and the ring body, and it is fixed to the eaves gutter, and the opening is protected from multiple pieces of debris. The dust guard part is formed by being surrounded by debris, and it can be installed more easily than conventional methods that require a separate dust guard member, and can be constructed with fewer parts, improving workability. It is a thing,
Moreover, since multiple support pieces are located on the inner circumference side of the dust prevention piece, double dust protection can be achieved by the dust prevention piece and the support piece. Since it can be done above the eaves gutter, it can be screwed together more easily than in the past, which also improves workability.
