Description

  The present invention relates to an eaves drain that is disposed at a connecting portion between the eaves and the eaves and drains the eaves from the eaves to the eaves.

  In a building such as a house, rainwater that flows down from a roof or the like due to rain is received by the eaves installed at the eaves and then drained through the eaves connected to the eaves. In the eaves, a drainage port is formed through the inside and outside of the bottom wall at the connecting portion with the eaves, and the eaves are connected to the eaves eaves through the drainage port. In order to connect the eaves and the eaves, conventionally, the eaves drain is disposed as a kind of joint, and the eaves drain is connected to the eaves and the eaves while draining from the eaves to the eaves. It is possible.

  As such eaves drains, for example, those described in Patent Documents 1 and 2 are known. The eaves drain includes an upper cylinder and a lower cylinder, and the bottom wall of the eaves is formed between the upper cylinder and the lower cylinder around the drain port formed in the bottom wall of the eaves. It is clamped between and attached, and a collar is connected to the lower cylinder.

  In the eaves drain described in Patent Document 1, the upper end opening of the upper cylindrical body protruding upward from the bottom wall of the eaves is formed by being erected by a rod, and is long in the rainwater drainage direction. Covered by a rectangular mesh.

  In the eaves bowl drain described in Patent Document 2, the upper cylindrical body is provided with a hemispherical mesh body disposed inside the eaves bowl at the upper end protruding upward from the bottom wall portion of the eaves bowl. ing.

All of the above eaves drains are trapped with dust such as fallen leaves flowing in the eaves by the net provided on the upper cylinder, preventing them from flowing into the eaves and preventing clogging of the eaves To be able to.

  However, in the eaves bowl drain described in Patent Document 2, the lower end of the mesh body is disposed on the bottom wall of the eaves bowl. As a result, there is a risk that the amount of drainage will be reduced, and it will eventually be impossible to drain toward the dredging. This problem can be solved by periodically removing dust, but it is maintenance at a high place, eaves, and it is undeniable that it takes time and effort.

  The eaves bowl drain described in Patent Document 1 is described in Patent Document 2 because the upper end opening of the upper cylindrical body is arranged at a slightly higher position from the eaves wall bottom wall part as the rod body is erected. Compared to the eaves drain, which is considered to be able to suppress a decrease in drainage capacity, the upper end opening is still located slightly higher than the bottom wall of the eaves, In addition, since the mesh body only covers the upper end opening in a flat shape, as dust such as fallen leaves accumulates, the dust accumulates not only in the mesh body but also in the portion where the rod body is disposed and clogs. Reduction of drainage can occur.

  The present invention has been made in view of the circumstances as described above, and provides an eaves drain that can reliably capture dust such as fallen leaves and can maintain drainage performance without being clogged by dust accumulation. It is a problem.

  The present invention has the following features in order to solve the above problems.

  According to a first aspect of the present invention, an upper cylindrical body and a lower cylindrical body are provided, and the bottom wall portion of the eaves ridge is disposed below the upper cylindrical body around the drainage port formed through the inside and outside of the bottom wall portion of the eaves ridge. In an eaves drain that is attached to and sandwiched between the side cylinders, a ridge is connected to the lower cylinder, and drains from the eaves to the eaves, the upper side that protrudes upward from the bottom wall of the eaves eaves At the top of the cylinder, there are a drainage part formed with several legs standing up at intervals that can be drained, and a filter part formed in a mesh shape. It is arranged on the upper side and protrudes upward.

  In a state where the second invention has the front ear part and the rear ear part in the first invention, and the upper end of the rear ear part is attached to the eaves located below the upper end of the front ear part, The upper end of the filter part does not protrude from the upper end of the rear ear part of the eaves but is arranged near the upper end of the rear ear part.

  According to the first aspect of the present invention, on the upper part of the upper cylindrical body protruding upward from the bottom wall portion of the eaves bowl, a drainage portion formed by standing up with an interval where several legs can be drained, A filter part formed in a mesh shape is disposed, and the filter part is disposed on the upper side of the drainage part and protrudes upward. Therefore, the filter part for capturing dust such as fallen leaves is a conventional drainage for eaves Therefore, even if debris accumulates, clogging is unlikely to occur in the drainage part located below the filter part, and rainwater can be drained sufficiently. Performance can be maintained.

  According to the second aspect of the invention, the effect of the first aspect of the invention can be achieved more reliably while preventing the filter portion from being exposed.

  1 and 2 are a cross-sectional view and a plan view, respectively, showing an embodiment of an eaves drain according to the present invention together with an attached state.

  The eaves drain 1 shown in FIGS. 1 and 2 includes a cylindrical upper cylindrical body 2 and a lower cylindrical body 3. In the attached state, the upper cylindrical body 2 is connected to the bottom wall portion 5 of the eave cage 4 at the connection portion between the upper portion 6 projecting upward from the bottom wall portion 5 of the eave cage 4 into the interior of the eave cage 4 and the eaves 7. It has a lower portion 9 which is inserted into a circular drainage port 8 penetrating the formed inside and outside and protrudes downward from the bottom wall portion 5 of the eaves wall 4. The lower cylinder 3 is connected to the outside of the lower part 9 of the upper cylinder 2 by screwing, fitting or the like. The eaves drain 1 is formed by the connection between the upper cylinder 2 and the lower cylinder 3. The lower cylinder 3 may be connected to the inside of the lower part 9 of the upper cylinder 2. The flange 7 has an upper end inserted inward from the lower end of the lower cylindrical body 3 and is fitted and connected to the lower cylindrical body 3. The flange 7 can be fitted from the outside of the lower cylindrical body 3.

  The outer diameter of the upper portion 6 of the upper cylinder 2 is slightly larger than the diameter of the drain port 8 formed in the bottom wall portion 5 of the eaves 4, and the outer diameter of the lower portion 9 is slightly smaller than the diameter of the drain port 8. Therefore, the upper cylinder 2 and the lower cylinder 3 are connected by connecting the lower cylinder 3 to the lower part 9 in a state where the lower part 9 is inserted from above the drain port 8 and penetrated downward. The eaves drain 1 is formed, and the eaves drain 1 is attached to the connecting portion between the eaves 4 and 7. In the mounted state, the eaves drain 1 holds the bottom wall portion 5 around the drainage port 8 in the eaves 4 between the upper cylindrical body 2 and the lower cylindrical body 3, so that a stable mounting state is obtained. It is done. The connection of the eaves 7 can be performed in a state where the eaves drain 1 is attached to the eaves 4 in this way.

  In addition, in the eaves bowl drain 1 shown in FIGS. 1 and 2, in the mounted state, four or more pieces are provided on the upper part 6 protruding upward from the bottom wall part 5 of the eaves bowl 4 to the inside of the eaves bowl 4. The drain part 11 formed by standing up on the circumference with a space between the leg parts 10 and the filter part 12 formed in a mesh shape are disposed.

  In the drainage part 11, a drainage gap 13 is formed between two adjacent leg parts 10 so that relatively large dust such as fallen leaves does not pass therethrough, and rainwater can be drained. The drainage gap 13 allows rainwater in the eaves cage 4 to flow to the drainage port 8 in the drainage part 11 and drain into the cage 7 through the lower part 9 and the lower cylinder 3.

  The filter part 12 is formed from a mesh made of metal or resin, and is disposed above the drain part 11 and protrudes upward. The shape of the filter unit 12 has a shape along the bottom and side surfaces of a bottomed cylinder, and as a shape, various hat types such as a shape along a hemispherical surface, a cap type, etc. can do. The upper end of the filter part 12 is disposed in the vicinity of the upper end of the rear ear part 14 so as not to protrude from the upper end of the rear ear part 14 slightly lower than the rear ear part 14 of the eaves cage 4 in the attached state. The upper end position of the filter unit 12 is higher than the conventional arrangement position of the mesh body described in Patent Documents 1 and 2, for example.

  The eaves bowl 4 has a rear ear portion 14 at the upper end of a rear wall portion 15 erected substantially vertically from the bottom wall portion 5, and is extended frontward and inclined obliquely from the bottom wall portion 5. A front ear portion 17 is provided at the upper end of the wall portion 16. The upper end of the rear ear portion 14 is located below the upper end of the front ear portion 17. The front ear portion 17 and the rear ear portion 14 are portions that are locked to a locking portion included in a fixture for fixing the eaves rod 4 to the eave tip and can be easily attached by fitting.

  Thus, in the eaves drain 1 shown in FIGS. 1 and 2, the drainage part 11 and the filter part are provided in the upper part 6 of the upper cylindrical body 2 projecting upward from the bottom wall part 5 of the eaves part 4 in the attached state. 12 and the filter unit 12 is disposed on the upper side of the drainage unit 11 and protrudes upward. The filter unit 12 is disposed at a higher position inside the eaves bowl 4 than the conventional eaves bowl drain, and the upper end is the eaves bowl. 4 is located in the vicinity of the upper end of the rear ear portion 14, dust such as fallen leaves can be reliably captured by the filter portion 12 formed in a mesh shape, and even if dust accumulates and accumulates, the filter portion 12 is not easily clogged, and the drainage gap 13 formed between the legs 10 of the drainage part 11 has a sufficient size for drainage. Low drainage performance Little. Drainage performance is maintained high. The amount of dust such as fallen leaves in the eaves drain 1 is increased, the maintenance period for removing accumulated dust can be lengthened, and the labor required for maintenance can be saved.

  Even if dust such as fallen leaves accumulated on the filter unit 12 is peeled off and dropped, the drainage gap 13 in the drainage unit 11 is smaller than the size of the relatively large dust, and therefore There is almost no possibility that the fallen dust will pass through the drainage gap 13 and flow out into the trough 7. Clogging with garbage such as fallen leaves of the cocoon 7 is sufficiently suppressed.

  Furthermore, even if the filter part 12 is arranged at a high position, the upper end of the filter part 12 does not protrude from the upper end of the rear ear part 14 of the eaves basket 4, and the filter part 12 remains inside the eaves bowl 4, The filter part 12 is not exposed and the appearance of the building is not impaired.

It is sectional drawing which showed one Embodiment of the drainage for eaves of this invention with the attachment state. FIG. 2 is a plan view showing the eaves drain shown in FIG. 1 together with an attached state.
