BACKGROUND OF THE INVENTION This invention relates to a gutter lid, and its purpose is to attach a detachable stopper to a substantially U-shaped gutter so that the gutter can be easily removed to clean the gutter. It is an object of the present invention to provide a gutter lid that can be easily carried out and that does not store water in a step portion with a road surface and can favorably introduce rainwater or the like into the gutter.

[0002]

2. Description of the Related Art Conventionally, as a gutter lid, a square cast iron plate having water inlets formed in a grid pattern is generally used, and it is simply laid over both upper ends of the gutter. It was placed in the state and the gutter was covered. However, such a conventional gutter lid is heavy because it is made of iron, and it is not easy to remove it from the gutter and move it to another place. Therefore, there has been a drawback that the frequency of cleaning work for dust or the like accumulated in the gutter tends to be inevitably reduced or insufficient.

Further, since it is made of iron, the dimensional accuracy with respect to the side groove is poor, and since iron is plastic and has no restoring force, the central portion is lowered due to heavy objects such as automobiles or frequent human bodies. When deformed into a curved state, both sides float up from the gutter, not only hindering traffic, but there was a risk of catching a foot on the raised side edge. In addition, in the case where the lower surface has a positioning protrusion for preventing displacement with respect to the side groove,
There is also a drawback that the inner wall surface of the gutter is damaged.

Furthermore, since the plate-shaped lid is buried substantially flush with the road surface in the gutter and is simply placed on the end face, a step is formed between the road surface and the upper surface of the lid. However, rainwater or the like often does not smoothly flow into the water inlet on the upper surface of the lid and accumulates in the above-mentioned step portion, and there is a drawback that it does not fully function as a gutter lid. Furthermore, there is a problem of noise when a car or a human body gets on with a lot of force.

In view of such a situation, Japanese Utility Model Publication No. 2-18147, Japanese Utility Model Publication No. 60-186395 and Japanese Utility Model Publication No. 60-100486 disclose groove lids with improved safety. ing. First of all, fairness 2-
In Japanese Patent No. 18147, two flexible connecting feet are fitted between adjacent water passage holes of a water passage groove lid formed by arranging a large number of water passage holes in rows, and the locking claws of the water passage holes are formed. Disclosed is a non-slip member for a water passage groove lid that is attached by locking to the inner peripheral edge on the adjacent side. In Japanese Utility Model Laid-Open No. 60-186395, in order to prevent warpage and distortion of a conventional flat plate-shaped groove lid, a little inward from both end surfaces of an arch-shaped groove lid having a loose cross section or a trapezoidal groove lid. A channel member is provided on the back surface of the channel material, and a stay having a reinforcing rib formed by cutting and raising that matches the shape of the back surface of the groove lid is provided at the center of the back surface of the channel material, and the outer edge of the reinforcing rib is fixed by welding. There is disclosed a groove lid provided with a stopper for preventing the groove lid from moving in the width direction by utilizing the concave grooves facing each other in the channel. Actual Kaisho 60
In Japanese Laid-Open Patent Publication No. 100486, a reinforcing stay is provided slightly inward from both end surfaces of a groove lid whose cross section has a loose arch shape.
There is disclosed a groove lid in which a fixing bracket made of a set of a stopper bent in a direction perpendicular to the reinforcing stay is slid and fixed so that the reinforcing stay can be freely slid and fixed.

[0006]

However, the "non-slip member" disclosed in Japanese Utility Model Publication No. 2-18147 has the following problems.
The groove lid itself does not prevent it from slipping on the upper surface of the groove, but it is a technology that prevents slippery on the surface of the groove lid to ensure the safety of pedestrians. There was a problem that it could not prevent warping. On the other hand, since the "stopper" shown in the "groove cover" disclosed in Japanese Utility Model Laid-Open No. 60-186395 is formed of a U-shaped elastic wire, the adhesion to the inner wall of the gutter is not sufficient, There is a problem that it is not possible to favorably prevent the positional deviation of the groove lid. Moreover,
There is also a problem that the groove lid is easily damaged while being repeatedly removed from the groove for the purpose of cleaning or the like, and the strength is not sufficient. Further, in this disclosed technique, since the groove cover has an arch shape or a trapezoidal cross section, the cover effect on the gutter is better than that of a flat plate, but there is a step with the road surface. There is also a problem that rainwater and the like are stored in this step portion and the drainage function of the road surface is deteriorated. Further, the fixture shown in the groove lid disclosed in Japanese Utility Model Laid-Open No. Sho 60-100486 is a flat plate-shaped stopper different from the wire rod as described above, but the adhesion to the inner wall of the groove is still insufficient. At the same time, there is a problem that the work of tightening the fixing bracket and the reinforcing stay with each use is complicated. Moreover, since the cross section is arched, there is a problem that a step is formed between the road surface and rainwater or the like is stored in the step.

Therefore, in the industry, it can be simply and easily attached to an opening such as a side groove in a state where it fits accurately and safely, and it is easy to remove and clean the inside of the side groove easily. It has been desired to create a gutter lid that is excellent in stability such that it does not cause displacement or warpage and that can collect rainwater and the like on the road surface well and guide it into the gutter.

[0008]

According to the present invention, the cross section is approximately U.
A lid for a gutter made of a hard synthetic resin that covers a gutter-shaped gutter, and the gutter lid has a lid plate portion having a width substantially equal to the inner dimension of the gutter, and the vicinity of both end portions of the lid plate portion. Each of which includes a side plate part extending downward, a plurality of rib parts projecting from the side plate part toward the inner wall of the side groove, and a flange part extending laterally from both end parts of the lid plate part. Becomes
A water inlet is formed in the lid plate portion, the rib portion is projected slightly inward from the lid plate portion in a direction orthogonal thereto, and at least one rib portion of the plurality of rib portions is formed. An engaging groove is provided in the engaging groove, and an elastic cap made of rubber or the like is detachably attached to the engaging groove, and a tip portion of the flange is bent downward at a substantially right angle to form a bent portion. Provided is a gutter lid characterized in that a bent portion is provided with a predetermined thickness to form a step with an adjacent road surface and a plurality of water inflow notches are formed in the step. By doing so, the above-mentioned conventional problems are solved.

[0009]

Since it is made of hard synthetic resin, it can be manufactured with high dimensional accuracy for the side groove. Moreover, since it has an elastic force, it can be immediately restored to the deformation caused by the pressurization of gravity, and can always be attached to the gutter in a desired state. Further, when gravity is applied to the lid plate portion, the rib portions on both sides which are inclined slightly inward and are easily bent,
The inner wall surfaces of the side groove are in close contact with each other and become more and more stable, and there is almost no displacement with respect to the side groove. Therefore, there is no risk of getting in the way or getting caught. Since the flange is a step with the road surface, it is easy to install and remove, and since a notch for water inflow is formed in this step, rainwater etc. on the road can be cut off with this notch. Since it flows into the side groove through the gap between the adjacent rib portions, rainwater does not collect in the step portion. In addition, because it is made of hard synthetic resin and is extremely lightweight, it can be easily removed and the cleaning work inside the gutter can be done easily, and noise caused by riding a car etc. The problem can be solved. At least one rib portion of the plurality of rib portions is provided with an engagement groove, and the elastic cap is detachably attached to the engagement groove, so that the gutter lid is provided on both inner wall surfaces of the gutter groove. Since they are more closely attached and arranged in a stable state, the lid will not be displaced with respect to the side groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the gutter lid according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view of an embodiment of the present invention, FIG. 2 is a front view cut at a central portion thereof, and FIG. 3 is a right side view of a part thereof. In these drawings, the gutter lid (1) of the present invention is integrally molded of hard synthetic resin and has a planar rectangular shape having a width substantially equal to the inner dimension of the concrete gutter (2) having a substantially U-shaped cross section. The lid plate portion (11), the rectangular plate-like side plate portions (12) protruding in the downward orthogonal direction from the portions near both side end portions of the lid plate portion (11), and the both side plate portions (12), respectively. A plurality of ribs (13) each formed in a shape slightly inclined inward with respect to the lower orthogonal direction at the outer position of the cover, and laterally extending from both end parts of the cover plate part (11). And a flange portion (14) that is formed.

Since the rib portion (13) projects slightly inward from the orthogonal direction to the lid plate portion (11), it can be brought into close contact with the inner wall surface of the side groove (2). Cover plate (1
In 1), water inflow holes (16) are bored in a row of five in each of guide groove portions (15) formed by bulging both side portions upward in a curved shape and formed in the width direction at regular intervals. ing.
Further, the flange portion (14) extends laterally from both end portions of the lid plate portion (11) to a length substantially equal to the thickness of the side groove (2), and each tip portion thereof bends downward at a substantially right angle. The tip bent portion (18) serves as a step with the road surface, and a plurality of water inflow notches (19) are formed.

Further, the rib portion (13) is provided with an engaging groove (17) for engaging an elastic cap described later. Specifically, as shown in FIG. 4 showing a cutting plane, at least one rib portion of the plurality of rib portions (13), and more preferably at least two positions on both side portions on the side plate portion (12) side. An engaging groove (17) is provided in the rib portion (13), and an elastic cap (3) such as rubber is retained in the engaging groove (17) so as to be attached to each rib portion (13) in a covered state. Therefore, when the elastic cap (3) is attached to the engaging groove (17) of the rib portion (13) in this way, when the lid (1) is arranged in the side groove (2), each elastic cap (3) is attached. ) Is attached to the inner wall surface of the side groove (2) in close contact with the inner wall surface of the side groove (2). Therefore, the elastic cap (3) is attached to the rib portion (13).
When the gutter lid (1) is placed on the upper end of the gutter (2) after the cover is attached, the ribs (1
Guided by 3), the elastic cap (3) is slidably joined to the inner wall surface of the side groove (2). In the embodiment shown in FIG. 3, an elastic cap (3) is capped on all ribs (13), but this elastic cap (3) is shown.
Need only be provided at a total of four locations on both ends of each side, or may be provided at one location.

Since the gutter cover (1) is integrally molded of hard synthetic resin, it can be manufactured with high dimensional accuracy with respect to the gutter (2). Then, when a large gravity is applied, each rib portion (13) having a shape that is slightly inclined inward and easily bent is pressed against the inner wall surface of the side groove (2) through the elastic cap (3). Thereby, the gutter (2) is brought into close contact with the gutter (2) and becomes more stable, and the gutter (2)
On the other hand, there is almost no misalignment, and it covers the drawback of the synthetic resin being lightweight and can be prevented from rising or pulling out. Moreover, if gravity is released, it will be deformed by pressure due to its own restoring force. Resolves immediately. Therefore, the gutter (2) is always attached in a desired state without obstructing passage or catching a foot.

Further, since it is made of a hard synthetic resin and is extremely lightweight, it can be easily removed and the cleaning work inside the gutters can be done easily. There is no problem of rusting, and the problem that the inner wall surface of the gutter is damaged by the elastic cap (3) can be solved. Further, the flange portion (14)
Although there is a step between the road surface and the road surface, rainwater, etc., passes through the gap between the notch (19) of the flange (14) and the adjacent rib (13) and enters the gutter (2). Since it flows in, rainwater does not accumulate on the stepped portion unlike in the conventional case.

By molding with a hard synthetic resin,
It is also possible to optionally insert-mold metal to reinforce a required portion, and if a coloring agent is mixed and colored, a lid having an extremely aesthetically pleasing appearance can be obtained.
At this time, if fluorescent paint is mixed, there are various advantages such as being able to obtain a safety function at night.

Each of them is shown, and in this embodiment as well, the functions substantially similar to those of the above-mentioned two embodiments are obtained, and therefore, those substantially equivalent thereto are designated by the same reference numerals and the description thereof will be omitted. The external shape is substantially the same as that of the embodiment shown in FIGS. 1 to 4, except that the water inflow holes 22 are partly formed on both sides of the lid plate portion (11) and the side plate portion (12) is located laterally. The only difference is the configuration formed beyond. This embodiment is particularly effective in places where it is necessary to allow water to flow into the gutter (2) from both sides.

As described above in detail, the present invention has a cross section of approximately U.
A lid for a gutter made of a hard synthetic resin that covers a gutter-shaped gutter, and the gutter lid has a lid plate portion having a width substantially equal to the inner dimension of the gutter, and the vicinity of both end portions of the lid plate portion. Each of which includes a side plate part extending downward, a plurality of rib parts projecting from the side plate part toward the inner wall of the side groove, and a flange part extending laterally from both end parts of the lid plate part. Becomes
A water inlet is formed in the lid plate portion, the rib portion is projected slightly inward from the lid plate portion in a direction orthogonal thereto, and at least one rib portion of the plurality of rib portions is formed. An engaging groove is provided in the engaging groove, and an elastic cap made of rubber or the like is detachably attached to the engaging groove, and a tip portion of the flange is bent downward at a substantially right angle to form a bent portion. A gutter lid characterized in that a bent portion has a predetermined thickness to form a step with an adjacent road surface and a plurality of water inflow notches are formed in the step. Since it is made of synthetic resin, it is lightweight, and since it has a step portion with a predetermined thickness, it can be easily attached to and removed from the side groove, and the cleaning work inside the side groove can be performed easily. In addition, it has a plurality of ribs that are projected slightly inward from the side plate toward the inner wall of the side groove, and at least one of the ribs is detachably attached with an elastic cap. Therefore, when gravity is applied to the lid plate portion, the rib portion is slightly inclined inward so that the rib portion is easily bent, and further, the rib portion closely adheres to the inner wall of the side groove to exhibit a retaining action. , By at least one rib portion being capped with an elastic cap, the adhesion with the inside of the gutter is further improved, and the gutter lid is kept in a stable state without displacement. It has an excellent effect that it is possible to do so and that the safety for pedestrians is good. Further, a notch is formed in the step portion with the road surface, and water from the side can be guided into the gutter through the gap between the adjacent rib portions from this notch portion, so rainwater etc. It is possible to obtain an effect that the drainage and water collection performance of the road surface is good without being stored. The gutter can be manufactured with high precision, and due to its own elastic force, it can be easily deformed and restored instantly due to the pressure of gravity, and because it is excellent in stability, it obstructs passage and catches your foot. There is nothing to do. Furthermore,
