The present invention relates to a grating used as a square or circular plant protector installed around the base of a plant for protection.

[Prior Art] Conventionally, this type of grating has been constructed by installing a plurality of grating units in sequence over the U-shaped groove, for example, in the case of a groove cover for a U-shaped groove, and also using a protector to protect the base of the plant. In this case, it is constructed by sequentially installing multiple arc-shaped gratings in parallel.

However, in any case, since conventional gratings are simply a plurality of grating units installed in parallel in sequence, they are often stolen or removed by mischief. In addition, in the case of a gutter cover, since cars may pass over it, there is a possibility that it may be moved or removed from its designated position by car tires, creating a danger such as obstructing traffic. There is also gender.
In addition, since conventional grating units simply have parallel slots in a material such as an iron plate, even if a large number of such grating units are installed in parallel, the appearance is extremely plain, which is bad for urban aesthetics. I don't like it either.

[Problems to be Solved by the Invention] The present invention eliminates the above-mentioned drawbacks of conventional gratings, and fixes each grating unit at the grating installation location. It is an object of the present invention to provide a grating that is completely free from the risk of being lost or creating a danger to traffic.

It is intended to provide a grating.

[Means for Solving the Problems] As a means for solving the above-mentioned problems, the present invention provides a grating in which a plurality of grating units are sequentially installed in parallel on a support frame provided at the grating installation location. A hook portion is formed in the lower half of one end surface of the grating unit to protrude to the side thereof, and a hook portion opening downward to receive the hook portion is formed in the lower half of the opposite end surface of the grating unit. A fixing means is provided for forming a groove and fixing the grating unit to the receiving frame, and the hook portion of one grating unit is fitted into the hook portion receiving groove of the next grating unit, so that the plurality of grating units can be fixed to the above-mentioned receiving frame. The present invention provides a grating characterized in that the grating units are installed in parallel on a receiving frame, and each grating unit is fixed to the receiving frame by the above-mentioned fixing means.

The means for fixing the grating unit to the receiving frame is such that one end is fitted into a panel clip receiving hole formed on the side surface of the grating unit, and the other end is elastically engaged with the lower side of the receiving frame to fix the grating unit to the receiving frame. It is best to use a spring clip to secure it to the

Further, the means for fixing the grating unit may be a stopper for screwing the above-mentioned hook portion.

In this case, the grating unit is fixed more strongly, and the head of the stopper is covered by the adjacent grating unit, resulting in an excellent appearance.

Each grating unit has ribs integrally formed on its lower surface to provide the necessary strength, but the surface shall display an aesthetically pleasing pattern such as a flower or animal without showing any ribs. .

By applying a color to the surface of each of the gratings arranged in parallel on one receiving frame, the grating as a whole can have a harmonious aesthetic appearance.

[Embodiments] The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 is a plan view showing an embodiment of a grating according to the present invention, and FIG. 2 is a sectional view taken along the line - in FIG.

Figures 1 and 2 show an embodiment in which the present invention is applied to a groove cover of a U-shaped groove. , 3 shows the grating of the present invention, and this grating has a plurality of grating units 4 on the receiving frame 2.
It is constructed by sequentially installing in parallel.

FIG. 3 shows a grating unit 4, which has a large number of slots 5, and a hook portion 6 projecting laterally is integrally formed in the lower half of one end surface of the grating unit 4. In the lower half of the opposite end,
A hook-receiving groove 7 opened downward is formed to receive the hook. Furthermore, a spring clip receiving hole 9 is formed in the side surface of the grating unit 4 to receive one end of a spring clip 8 (FIG. 6) for fixing the grating unit to the receiving frame 2. When installing the grating, a plurality of grating units 4 are placed in parallel on the receiving frame 2 while fitting the hook portion 6 of one grating unit 4 into the hook portion receiving groove 7 of the next adjacent grating unit 4. Then, one end of the spring clip 8 is fitted into the spring clip receiving hole 9 of each grating unit 4, and the other end of the spring clip 8 is elastically engaged with the lower side of the receiving frame 2 (FIG. 6). In this way,
The grating units 4 are sequentially connected together by hooks and hook receiving grooves, and are fixed to the receiving frame by spring clips.

The above embodiment shows an example in which the present invention is applied to a U-shaped groove cover, but the present invention is not only applicable to a catch basin or drain cover, but also as described above. It can also be applied to gratings that protect the base of plants in parks, etc. In such cases, the grating units should be combined into a ring shape or a square shape with a circular hole in the center, which corresponds to the shape of the grating installation location. A grating unit will be used. In addition, in the case of a large-sized gutter cover, in order to hold the grating more firmly so that it does not come off due to the tires of automobiles passing over it, the grating shown in Figure 1 can be used in place of or together with the spring clips described above. 1
The grating may be screwed to the receiving frame using bolts as shown at 0.

7 and 8 show other embodiments of the grating unit in the grating according to the present invention. These grating units have a flower pattern on the surface and holes 11 for water passage between them.

In the embodiment shown in FIGS. 7 and 8, a circular connecting hook 12 is provided on one side edge, and a hook receiving groove 13 is provided on the other side edge. In these embodiments, a dish-shaped circular recess 12a is formed in the hook portion 12, and a bolt receiving hole 12b is formed in the center, and after a stop bolt 14 is inserted and fixed therein, an adjacent grating unit is covered. By fitting the hook portion 12 and the hook portion receiving groove 13, the grating unit is completely fixed, ensuring even more safety, and furthermore, even when a car passes over it, no noise is generated. By setting an adjacent grating unit on top of the
The head of the stop bolt is not visible from the outside, so the appearance can be maintained. When fastening with bolts,
It can also be bolted to this using a drive anchor.

However, apart from standard products, it is possible to achieve a desirable effect on urban aesthetics by using grating units with floral patterns, animal patterns, or various markings, depending on the preference of the builder. In addition, the necessary strength can be obtained by forming a rib on the back side, avoiding the through-holes necessary for passing rainwater, etc. Furthermore, when installing new cross ditches and side gutters, by using a separate support frame, construction can be done more quickly than with conventional methods, and when replacing conventional ones, it can be used without a support frame.

[Effects of the invention] In the grating of the invention, each grating unit is integrally connected by fitting the hook portion and the hook receiving groove, and the hook portion receiving groove is opened downward. Therefore, it is difficult to lift that one grating unit upward by itself. Furthermore, since each grating unit is fixed to the receiving frame by means of fixing means such as spring clips or fixing bolts, it is possible to prevent part or all of the grating unit from being lost due to theft or mischief. In addition, each grating unit is fixed to the receiving frame with spring clips, so even if a car passes over it,
This also prevents the grating from coming off or rattling. When attaching a spring clip, it can be easily attached by inserting the spring clip through the slot 5 of the grating and pressing it in to the side, but special tools are required to remove it. So, as a prank,
Even if you try to remove it, it will not come off easily.Furthermore, if each grating unit is fixed to the receiving frame with fasteners such as spring clips and bolts, the possibility of the grating coming off due to large external force being applied to it will be further reduced. Ru.

In addition, each grating unit has a pattern of flowers, animals, etc. on its surface, and the surface is constructed so as not to show any stiff bones in order to provide the necessary strength, thereby creating gratings that are extremely aesthetically pleasing. Furthermore, by applying a certain harmonious color to this surface, it is possible to obtain a beautiful fashionable appearance that was previously unobtainable, and this has a great impact on the aesthetic appearance of the city. be.

Furthermore, as mentioned above, when fixed with stop bolts, even more safety can be maintained.
Noise generation is also prevented.

However, as standard products or by order,
By applying patterns such as floral patterns, animal patterns, marks, etc. on the surface, you can obtain an unprecedented beauty.
In addition, by forming ribs on the back side of the grating, avoiding the through-holes that are necessary for the passage of rainwater, etc., it is possible to maintain sufficient strength required for the grating. When installing new cross ditches and side gutters, using a separate support frame allows for faster construction than before, and when replacing conventional ones,
It can be constructed as is without a support frame.
