[0016] Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings.

[0017] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art.

[0018] Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted.

[0019] First, the grating structure according to the first embodiment of the present invention is described in FIGS. 1 to 8 as follows.

[0020] In the present embodiment, the one-sided grating comprises a grating body (10) having a square shape and a plurality of rainwater inflow holes (11) formed in an elongated shape at regular intervals, an opening / closing plate (20) configured to rotate about a pivot axis (30) at the bottom of the grating body (10) to perform the function of opening / closing the rainwater inflow holes (11), an elastic spring (40) provided in a shape that surrounds the pivot axis (30) of the opening / closing plate (20) to elastically support the opening / closing plate (20), and a water accumulation groove (21) formed at the front end of the opening / closing plate (20) to generate a load due to water accumulation.

[0021] At this time, the pivot shaft (30) is easily replaced through a fastening structure of a shaft bolt (31) and a nut (32), and a locking projection (31a) is formed on the nut fastening portion at the tip of the shaft bolt (31).

[0022] In addition, the water collection groove (21) is formed with an inclined surface at a certain angle, and a plurality of through holes (22) are formed at regular intervals on the bottom surface, and a stopper part (23) for limiting the opening / closing angle is extended at a certain angle at the rear end of the opening / closing plate (20).

[0023] Let us examine the effects of the installation of the grating of the present invention having such a configuration.

[0024] In the grating of the present invention, the opening / closing plate (20) provided at the bottom of the grating body (10) normally blocks the rainwater inlet hole (11), thereby preventing the entry of foreign substances such as cigarette butts, and the opening / closing plate (20) is opened when rainwater occurs.

[0025] That is, at this time, as rainwater flows in, it gradually accumulates in the water accumulation groove (21), and as the amount of rainwater accumulates beyond a certain amount, the opening / closing plate (20) rotates around the pivot axis (30) as shown in FIG. 8 due to the load action and opens, thereby opening the rainwater inflow hole (11).

[0026] In addition, since a stopper part (23) is extended at the rear end of the opening / closing plate (20), opening beyond a certain angle is restricted.

[0027] And, when the inflow of rainwater is no longer possible, the load action is released, and the opening / closing plate (20) is raised back to its original position by the elastic action of the elastic spring (40) mounted on the pivot shaft (30), thereby closing the rainwater inflow hole (11), and the remaining water in the water accumulation groove (21) can be discharged through the through hole (22).

[0028] Meanwhile, the pivot shaft (30) in this embodiment has a fastening structure of a shaft bolt (31) and a nut (32), which allows for easy assembly of the opening / closing plate (20), thereby providing the advantage of enabling quick replacement in the event of breakage or damage to the opening / closing plate (20).

[0029] Therefore, the rainwater grating of the present invention is capable of performing an opening and closing function in response to the load of rainwater, thereby exhibiting the effect of preventing the inflow of foreign substances and blocking odors.

[0031] Meanwhile, FIGS. 9 to 11 show a configuration according to a second embodiment of the present invention, in which it can be seen that the rainwater inlet hole (11) is formed in a two-row shape and two opening / closing plates (20) are arranged in the same direction.

[0033] Additionally, FIGS. 12 and 13 show a configuration according to a third embodiment of the present invention, in which it can be seen that the rainwater inlet hole (11) is formed in a two-row shape and two opening / closing plates (20) are arranged in a left-right symmetrical shape.

[0035] Additionally, FIGS. 14 and 15 show a configuration according to the fourth embodiment of the present invention, in which two paired fitting protrusions (12) are provided protruding in a left-right symmetrical structure on one side of the grating body (10), and fitting grooves (13) are formed on the corresponding other side.

[0036] When such a configuration is achieved, when multiple gratings are installed in succession, they can be connected to each other by means of the interlocking protrusions (12) and interlocking grooves (13), thereby improving the effect of preventing detachment.

[0038] Meanwhile, FIGS. 16 to 18 illustrate a fifth embodiment of the present invention, wherein the opening / closing plate (20) is provided with a rubber pad (50) made of butadiene rubber (BR), a high-elasticity special rubber component, along the edge portion to perform the function of blocking odors through the gap between the bottom surface of the grating body (10).

[0039] In addition, a adhesion layer (51) is coated on the surface of the rubber pad (50) to improve adhesion to the bottom surface of the grating body (10) and maintain flatness.

[0040] At this time, the adhesive layer (51) preferably has a mixed composition in the ratio of 10-30% by weight of paraffin oil, 20-40% by weight of melamine resin, 5-20% by weight of behentrimosome chloride, 5-10% by weight of carbon black, 5-10% by weight of diethylaluminum chloride, 10-20% by weight of ammonium ferrous sulfate, 5-10% by weight of methylchloroisothiazolinone, 1-10% by weight of trehalose, and 1-10% by weight of citrate.

[0041] When such a configuration is achieved, when the opening / closing plate (20) is closed, the rubber pad (50) improves the adhesion function with the bottom surface of the grating body (10), thereby preventing the occurrence of gaps and effectively blocking bad odors.

[0042] In addition, the rubber pad (50) can be made of butadiene rubber material, thereby providing high elasticity, and the odor blocking function can be maximized by coating the surface with an adhesive layer (51).

[0043] In particular, since the adhesive layer (51) contains a mixture of paraffin oil and carbon black components, the lubricity and durability of the coating surface can be improved, and behentrimojum chloride functions as a catalyst for the melamine resin to improve coating stability, and diethylaluminum chloride suppresses bubble formation during the coating process to improve coating density, and ammonium ferrous sulfate and methylchloroisothiazolinone perform the function of suppressing deterioration and oxidation of the adhesive layer (51). In addition, trehalose, an additionally added disaccharide component, improves water tightness, and citrate performs the function of improving the antibacterial properties of the adhesive layer (51).

[0045] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the grating structure of the present invention can be implemented with various modifications by those skilled in the art.

[0046] For example, in the above embodiment, the rainwater inlet holes were described and illustrated as having a single or two-row structure, but if necessary, they can be manufactured with a multi-row structure of three or more rows.

[0047] Therefore, such modified embodiments should not be understood separately from the technical spirit or scope of the present invention, and such modified embodiments should be considered to be included within the appended claims of the present invention. Explanation of the symbols
