Description

The present invention relates to a dredge water collector for collecting rainwater from eaves.

The rain gutter water collector is connected to the water collector body for collecting rain water from the eaves, a drain cylinder extending outward from the bottom surface of the water collector body, and a lower part thereof. There has been provided a dredger water collector composed of a square elbow and an engagement ring for engaging the square elbow with the water collector main body from the outer periphery (for example, Patent Document 1).

The dredging water collector described in this publication integrally forms a drainage cylinder that becomes a drop port in a state of projecting downward at the bottom of the collector body, and connects the drainage cylinder and the square elbow via an engagement ring. It is connected, provided on the upper outer peripheral surface of the drainage cylinder with a long engaging protrusion in the circumferential direction to form a groove on the engaging protrusion, and provided with a protrusion on the inner peripheral surface of the engagement ring, The projection is inserted into the groove of the drainage cylinder so as to be rotatable, and the drainage cylinder of the water collector is mounted and connected in the engagement ring. Further, the engagement ring and the square elbow are rotatably connected with the same structure.

Thus, in the structure of the trap water collector in which the water collector main body and the square elbow are rotatably connected, the direction of the square elbow can be freely changed and the workability is convenient. However, when connecting to the square elbow, there is a case where a gap is generated at the corner of the joint surface between the drainage cylinder and the square elbow, and water leaks from the gap.

It is an object of the present invention to provide a dredger water collector that can be connected to a square elbow so as to prevent water leakage from a connecting surface with the square elbow.

As a result of diligent study to solve the problem, the present inventor has made the corner of the connection surface between the drainage cylinder 3 and the square elbow 8 to make the dredge water collector 10 difficult to leak water from the connection surface with the square elbow 8. It was found that filling the gap S that can be made is an important factor, and the present invention was completed.

The present invention includes a box-like box 2 having an open top, a drainage cylinder 3 extending outward from the bottom of the box, and an engaging protrusion 4 provided around the upper periphery of the drainage cylinder. A main body 1 of the water collector, an engagement ring 6 having a cylindrical shape and a protrusion 61 protruding from each of the axial end portions toward the inner periphery, and a cylindrical shape having one axial end A dredge water collector having a square elbow 8 having a projection 83 projecting from the portion toward the outer periphery, provided with an engagement ring 6 having a cylindrical wall 7 extending outward. is there. Furthermore, the inner surface of the cylindrical wall 7 is circular and the outer surface is square. Further, the inner surface of the cylindrical wall 7 is larger in diameter than the drainage cylinder 3, and the outer surface of the cylindrical wall 7 is smaller in diameter than the square elbow 8.

According to the present invention, the gap S formed at the corner of the connection surface between the drainage cylinder 3 and the square elbow 8 is closed, and a dredger that does not easily leak due to the connection with the square elbow 8 can be obtained.

The present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing the relationship between a dredger water collector 10 and a square elbow 8 showing an example of the present invention. FIG. 2 is a schematic cross-sectional view showing a fitting state of the water catcher 10 and the square elbow 8 showing an example of the present invention. FIG. 3 is a schematic cross-sectional view showing a fitting state between a water collecting device and a square elbow showing an example of the prior art.

In FIG. 1, reference numeral 10 denotes a water catcher, and a water collector main body 1 attached to an eaves tub (not shown), a drop mouth 21 projecting downward from the water collector main body 1, and a lower end portion of the drop mouth 21 are inserted. A square elbow 8 connected to the collar or not shown, and an outer end of the drop elbow 21 are engaged with the engaging protrusion 4 and the lower end is engaged with the square elbow 8. Engaging ring 6.

In the collector body 1, an opening 22 is provided on the bottom surface of the box body 2, and an opening (not shown) is provided in one or both sides of the side wall of the box body 2. Insert the eaves and use it. Then, rainwater flowing from the eaves wall flows in the direction of the drainage cylinder 3 from the bottom surface of the box body 2 and flows downward.

An engaging protrusion 4 is provided around the upper outer periphery of the drainage cylinder 3 that is tapered downward. The lower end of the drainage cylinder 3 is inserted into the upper opening of the square elbow 8.

The square elbow 8 is a rectangular tube-like joint, and there are some that do not change in angle from those having a certain angle. Further, the upper end of the square elbow 8 is a square cylindrical connecting portion 81 into which the lower end portion of the drainage cylinder 3 is inserted, and a rectangular cylindrical call or unshown connecting portion 82 is formed at the lower end. Further, a projection 83 is formed on the upper end of the rectangular tube-shaped connecting portion 81 so as to project outward.

The engagement ring 6 is a rotary joint composed of a short rounded rectangular tube that is inclined to fit the outer diameter of the square elbow 8 as it goes downward, and is connected to the collector main body 1 by interpolating the drainage cylinder 3. Is done. The engagement ring 6 is provided with a plurality of protrusions 61 projecting toward the inner circumference from the respective axial ends on the round cylindrical side, and the projection of the square elbow 8 on the outer peripheral wall of the square cylindrical side. An engaging groove 62 for elastically locking 83 is formed to project.

The cylindrical wall 7 according to the present invention is a rectangular cylindrical portion that extends outward from the lower portion of the engagement ring 6. It is provided in the lower part of the engagement ring 6 so as to extend in the outward direction. A gap S formed at the corner of the connection surface between the drainage cylinder 3 and the square elbow 8 in the conventional example of FIG. It is because the clearance gap S is closed by making 7 the size which can be fitted in the clearance gap S, and the dredged water collector 10 which is hard to leak by connection with the square elbow 8 can be obtained. As shown in FIG. 4, the inner surface of the cylindrical wall 7 has a circular shape whose diameter is larger than that of the drainage cylinder 3. The outer surface of the cylindrical wall 7 has a similar shape that is slightly smaller in diameter than the square elbow 8 so as to fit inside the square elbow 8. The length of the cylindrical wall 7 in the axial direction may be in an appropriate range as long as the cylindrical wall 7 can be fitted into the rectangular cylindrical connecting portion 81 of the rectangular elbow 8.

The water collector 10 and the square elbow 8 are connected via the engagement ring 6. Specifically, the protrusion 61 of the engagement ring 6 is engaged with the engagement protrusion 4 provided around the outer periphery of the drainage cylinder 3 to engage the water collector body 1 and the engagement ring 6. By connecting the projection 83 of the square elbow 8 with the engagement groove 62 of the engagement ring 6, the connection between the water collecting device 10 and the square elbow 8 is completed.

The material of the water collector 10 of the present invention is not particularly limited. For example, hard vinyl chloride resin, polyethylene resin, polypropylene resin, polycarbonate resin, acrylic resin, AES resin (acrylonitrile / ethylene-propylene rubber)・ In addition to thermoplastic resins (such as styrene resin), engineering plastics such as polyphenylene sulfide, or metals such as iron, stainless steel, copper, and aluminum may be used alone, or metal cores such as iron These materials may be used in appropriate combination, such as providing a hard vinyl chloride resin coating layer on both sides of the material.

In this way, the dredger water collector of the present invention provides the cylindrical wall 7 at the lower part of the engagement ring 6, thereby closing the gap S formed at the corner of the connection surface between the drainage cylinder 3 and the square elbow 8. It can be seen that even when a large amount of rainwater flows from the dredger to the dredger water collector 10, it is difficult for water to leak, and the dredge water collector 10 that is rotatably connected to the square elbow 8 can be easily obtained.

It is explanatory drawing which shows the relationship between the trap water collector which shows an example of this invention, and a square elbow. It is a schematic sectional drawing which shows the fitting state of the water collector and square elbow which show an example of this invention. It is a schematic sectional drawing which shows the fitting state of the water collector and square elbow which show an example of the past.
