Description

[Detailed description of the invention] The present invention relates to a device for removably attaching a strainer to a drainage opening provided in a drainage frame attached to a balcony of a building, etc. A locking piece hanging from the opening edge is provided on both sides of one end, the lower end of each locking piece projects toward the other end and then stands up to form a U-shaped piece, and further, from the upper end of the U-shaped piece A symmetrical approximately U-shaped piece in which a short and small protruding piece is formed extending toward the other end at a height lower than the upper edge of the opening, and is inserted from the end face of the protruding piece into the left and right side edges of the strainer that covers the opening. The strainer is characterized in that a cut groove is provided, and the cut groove is inserted into the locking piece from the end face of the protruding piece to the U-shaped piece, and the strainer is removably attached to the drain opening. Moreover, the purpose is to prevent the strainer from being stolen or lost by preventing the strainer from accidentally coming off in the attached state.

The attached drawing shows an embodiment of the present invention, and shows a water collection frame 1.
is made up of a lower body 2 and an upper body 3 stacked and fixed together, and the lower body 2 has a drain pipe 4 projecting downward on one side on the left side in Figure 2, and a drain pipe on the other side on the right side in Figure 2. A drainage gutter 5 communicating with the edge of 4 is provided. The upper body 3 has screws 6,
6 fixed to the upper surface of the lower body 2,
A connecting pipe insertion pipe 7 corresponding to the upper side of the drain pipe 4 is provided integrally, and a drain opening 9 is provided which matches the top of the drain gutter 5 and is surrounded on three sides by a frame piece 8. The connecting pipe insertion pipe 7 is not always formed, and may be closed by a canopy part 10 as shown by the chain line.

The above-mentioned water collection frame extends up to the vicinity of the upper edge of frame piece 8 to the floor a.
Embed and fix in concrete.

The drainage opening 9 of the water collection frame 1 illustrated above is provided in the ceiling plate 11 on which the connecting pipe insertion pipe 7 is erected. Locking pieces 12 slightly inclined diagonally to the right in FIG. 1 are formed by lowering them from the left and right sides of the mouth edge of 9. A U-shaped piece 13 is provided which protrudes and further rises diagonally to the right. The U-shaped piece 13 has the above-mentioned rising end 13a lowered from the upper edge of the frame piece 8 to correspond to the thickness of the strainer 16, and a short and small protruding piece 14 protrudes to the right from the end 13a. be installed horizontally. Further, a strainer support edge 15 having the same height as the protruding piece 14 is appropriately provided on the inner surface of the frame piece 8.

Strainer 16 with many drainage ports arranged in a mesh pattern
is plate-shaped and is fitted into the drain opening 9 in a substantially tight fit and supported by the strainer support edge 15, with locking pieces 17 protruding from both sides of the left edge in FIGS. 2 and 3. The protruding piece 1 is attached to the side edge of the protruding piece 1.
A symmetrical U-shaped notch groove 18 is provided to be inserted from the end surface of the 4. The protruding piece 19 on the rear side of the cut groove 18 (on the left side in FIG. 3) slightly shortens the length of the protrusion toward the left side in the same figure.

In this embodiment, the strainer 16 is erected at the right end of the protruding piece 14 as shown by the chain line in FIG.
, position it so that it fits into the protruding piece 14 of the cut groove 18, then push it in the direction of the end 13a, move it slightly downward at the U-shaped piece 13, and then press the locking piece 12. At the corresponding part, fold it down as shown by the chain line in Figure 2, pass it through the cut groove 18, and then fold it horizontally to install it.

In this attached state, the strainer 16 cannot be removed unless operated in the opposite manner to the insertion described above.

The strainer 16 is installed after the water collection frame 1 is fixed in advance with concrete on the floor a.

The present invention has the above-described configuration, and the strainer 16
can be attached to or removed from the drain opening 9 of the water collection frame 1 at any time, and once attached, there is no risk of loss as it will not come off involuntarily, and most people do not know how to remove it. There is little risk of theft, and handling is convenient.
