The rods are arranged at equal intervals along the outer peripheries of the upper and lower frames, and the gaps set on the upper surface are formed in substantially the same shape by the arrangement of the fine materials and set on the peripheral surface. This was realized by forming the gap by the spacing between the bars.

  Hereinafter, the present invention will be described with reference to embodiments shown in the drawings. FIGS. 1A and 1B are a plan view and a front view, respectively, showing a clogging preventer according to a first embodiment of the present invention. The clog prevention tool 2 according to the above embodiment is provided at the drainage port 10 of the basket or the outdoor floor 11. The clogging prevention device 2 includes an upper frame 4 in which a thin material 3 is bridged inside an annular outer peripheral frame 4A, and an annular lower frame 6 connected to the upper frame 4 via a bar 5. Is done. Each of the outer peripheral frame 4A and the lower frame 6 is formed of a stainless steel ring having the same diameter (for example, 130 mm in this embodiment).

  In the upper frame 4, the thin material 3 intersects at the frame center O and extends radially, and an extended end is welded to the outer peripheral frame 4A. The fine material 3 is formed of a stainless steel round bar. As shown in FIG. 1A, the fine material 3 is arranged at equal intervals in the circumferential direction of the annular outer peripheral frame 4A, and a gap S1 is defined by the fine material 3 and the outer peripheral frame 4A. ing. The gap S1 is defined by a straight isosceles side substantially corresponding to the radius of the circular outer peripheral frame 4A and an arc-shaped side corresponding to a part of the circumference of the circular outer peripheral frame 4A.

  The bar 5 has a predetermined length dimension L1 (for example, 100 mm in this embodiment), and extends along the circumferential direction of the annular frames 4A and 6 for each portion where the thin material 3 is connected to the outer frame 4A. The upper and lower ends are welded to the outer peripheral frame 4A and the lower frame 6, respectively. The bar 5 is composed of a stainless steel round bar. The bar 5 is provided with a predetermined interval (gap) S <b> 2 between the adjacent bars 5.

  As shown in FIGS. 1A and 1B, the lower frame 6 is provided with legs 7 to be inserted into the drain port 10. The leg 7 is bent and formed so as to be able to be rebounded. When the leg 7 is inserted into the drain port 10, it comes into pressure contact with the inner wall of the drain channel. Therefore, the upper and lower frames 4 and 6 and the bar 5 exposed on the drain port 10 are surely locked to the drain port 10 even if they receive a water flow caused by rainwater.

  By the way, the clogging prevention tool 2 according to the present embodiment is based on the size that may block the drain port 10 (diameter φx, see FIG. 3) when setting the gap S1 of the upper frame 4 by the arrangement of the thin material 3. That is, the size of the gap S1 is set based on whether or not the passage of the drain port 10 can be permitted. That is, the obstacle Ds is a small piece of a natural origin such as soil, sand, dust, humus or dead leaves, or an artificial origin such as a golf ball. The gap S1 of the upper frame 4 is set to a size that allows the passage of these small strips. For this reason, when these small pieces flow into the clogging prevention device 2 together with rainwater, the gap S1 of the upper frame 4 allows the flow into the drain port 10. Similarly, when the interval S2 between the bars 5 is set by the arrangement of the bars 5, the size is set to allow passage in advance according to the size of the obstacle Ds that can flow into the drain port 10. . That is, when the obstacle Ds is a small strip as described above, and the drain port 10 has an inner diameter φx that does not cause clogging due to the inflow of these small strips, the interval (gap) S2 between the bars 5 is: The size is set to allow passage of these small strips. For this reason, when small pieces flow into the clogging prevention tool 2, the gap S <b> 2 between the bars 5 allows the flow into the drain port 10.

  On the other hand, the gap S1 of the upper frame 4 or the interval S2 between the bars 5 is such that the obstacle Db is a natural product such as a large artificial product such as a piece of paper, a synthetic resin product, a can or a candy, or a large dead leaf. In addition, when it flows into the drain port 10 having the diameter φx, the size that can block the drain port 10 is set to a size that can prevent the inflow. That is, in the clog prevention tool 2 according to the present embodiment, the size of the gap S1 and the size of the interval S2 are respectively based on the size of the drainage port 10 having the diameter φx, and the obstacle Db having a size that may be blocked. Is set to a size that allows passage of an obstacle Ds having a size that does not cause a blockage. For this reason, in the clog prevention tool 2 according to the present embodiment, the fine obstacle Ds is discharged together with the rain water to the drain port 10, and only the large obstacle Db that may clog is prevented from flowing into the drain port 10. It has become. For this reason, compared with the conventional structure which arrange | positions the cover and net | network which have a small hole around the drain outlet, and even a small piece prevents inflow, rainwater is smoothly accumulated without the drainage 10 surrounding. Can be discharged, and soot and the outdoor floor 11 do not overflow due to rain.

  Next, the operation of the clogging prevention tool 2 according to the above embodiment will be described. In the clogging prevention device 2 according to the above embodiment, when the leg 7 is inserted into the drainage port 10 and locked, the lower frame 6 is grounded to the basket or the outdoor floor 11, and the upper frame 6 is disposed above the drainage port 10. An enclosure is formed by the thin material 3 extending radially across the frame center O on the inner side, the outer peripheral frame 4A, and the bars 5 arranged at equal intervals along the circumferential direction between the outer peripheral frame 4A and the lower frame 6. Is done. For this reason, when an obstacle Db (for example, a piece of paper, a synthetic resin product, a can, a bag, etc.) having a size that may block the drain port 10 flows in, the obstacle Db is blocked and the drain port Inflow to 10 is blocked. On the other hand, when an obstacle Ds (soil, sand, dust, humus or dead leaves, etc.) having a size that can flow into the drain port 10 flows in, an enclosure gap S1 formed by the upper frame 4 and the bar 5 is formed. , S2 is allowed to flow into the drain port 10. For this reason, these fine obstacles Ds do not accumulate on the clogging prevention device 2. The large obstacle Db remains blocked by the clogging prevention device 2 from flowing into the drain port 10. For this reason, the drain port 10 is not blocked by the large obstacle Db. Moreover, even if many large obstacles Db are gathered around the clogging prevention device 2, a space communicating with the outside air is always formed above the drainage port 10 by the upper and lower frames 4 and 6 and the bar 5. Therefore, the finer obstacle Ds is smoothly discharged to the drain port 10 together with the rainwater. Further, since the large obstacle Db gathers around the clogging prevention device 2, it is easy to find and remove during the inspection work.

  Next, a modified example of the clogging prevention tool 2 according to the first embodiment will be described. As shown in FIGS. 4A and 4B, the clogging prevention tool 12 according to the modification has a length L2 of the bar 15 that is half that of the bar 5 of the clogging prevention tool 2 according to the above embodiment. Except for the dimension (L2 = L1 × 1/2, that is, 50 mm), the clogging prevention device 2 has substantially the same configuration. In other words, the clogging prevention device 12 according to this modification has a height that is almost halved. For example, there is a restriction on the installation location such as a fence of a station building or a narrow space between the outdoor floor 11 and the roof. However, it can be used without cutting off part of the roof. For this reason, it can be used by selecting from various types according to the installation location.

  Next, a clogging prevention tool 22 according to a second embodiment of the present invention will be described. As shown in FIG. 5, the clogging prevention tool 22 according to the second embodiment has an annular shape between the outer peripheral frame 4 </ b> A and the lower frame 6 of the upper frame 4. On the other hand, the outer frame 24A and the lower frame 26 of the upper frame 24 are formed in a quadrangle (parallelogram) having substantially the same shape. The difference is that it extends parallel to the side of 24A and is connected to the outer peripheral frame 24A. The clogging prevention tool 22 is provided with a leg 27 to be inserted into the drain port 10 on the lower frame 26, and when it is inserted into the drain port 10, it comes into pressure contact with the inner wall of the drain channel.
