[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve the above-mentioned problems and make it difficult for soil and sand to be clogged in the gap between the inner surface of the receiving frame member and the end plate of the groove lid, thereby preventing the opening and closing of the groove lid. In addition, the leaf spring metal fittings are damaged by securing a required clearance even if a large lateral load is applied with the leaf spring metal fittings interposed between the inner surface of the receiving frame material and the end plate of the groove lid. Another object of the present invention is to provide a groove lid device that does not do so.

[0004]

[Means for Solving the Problems]

 The groove lid device of the present invention, which has solved the above-mentioned problems, is a groove lid device in which a groove lid is fitted and supported by a receiving frame material having an L-shaped cross section, and the tip of the groove lid has an arc shape at the upper edge of the end plate. It is characterized in that a short brim portion formed on an edge is integrally stretched. In addition, the lower surface of the short brim is formed to be an inclined surface facing upward, or the inner angle of the L-shaped frame member having a cross section of slightly larger than 90 ° facilitates the fitting of the groove lid to the frame member. It is a preferred embodiment that a packing is interposed between the receiving frame member and the groove lid so as to eliminate noise due to direct contact between the metal receiving frame member and the groove lid.

[0005]

[Action]

 If such a groove cover device is provided in the side groove, the transverse groove, or the upper surface opening of the water collecting basin, rainwater can be drained safely, like the conventional groove cover device of this type. Since the short brim portion, whose tip is formed as an arcuate edge, is integrally stretched on the upper edge of the end plate, the arcuate edge comes close to the inner surface of the receiving frame member. A large gap is not formed between the side surface and the end plate of the groove lid, and it is possible to eliminate the obstacle in opening and closing the groove lid that is caused by the clogging of the gap with earth and sand.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. Reference numeral 1 denotes a receiving frame member having an L-shaped cross section, which is provided at a side groove, a transverse groove, or an opening edge of an upper surface of a water collecting basin, and 11 denotes a groove lid fitted and supported by the receiving frame member 1. The frame member 1 may have an angle between the vertical plate portion 1a and the bottom plate portion 1b which is approximately 90 ° similar to the conventional one as in the first and second embodiments shown in FIGS. 1 and 2. If the angle between the vertical plate portion 1a and the bottom plate portion 1b is set to about 95 to 100 as in the third embodiment shown in FIG. 3, the fitting of the groove lid 11 to the receiving frame material 1 is further facilitated. It Further, although not shown, a large number of fine grooves may be arranged at required intervals so as to reach from the upper edge of the vertical plate portion 1a to the outer edge of the bottom plate portion 1b from the viewpoint of drainage measures.

On the other hand, in the groove lid 11 fitted and supported by the receiving frame member 1, a large number of vertical girder members 13 are stretched between the end plates 12 and 12 made of strip steel or the like at required intervals, and each vertical girder is extended. As is well known, a member 13 is connected by a horizontal member 14, but a short flange portion 15 in which an arcuate edge 15a is close to the inner surface of the vertical plate portion 1a of the receiving frame material 1 is provided at the upper edge of the end plate 12. Are integrally stretched, and this point is a characteristic configuration of the present invention. In the figure, 15b is an upwardly inclined surface formed as necessary on the lower surface of the brim portion 15 to further facilitate the fitting of the groove cover 11 to the receiving frame member 1, and 16 is the receiving frame member 1 and the groove cover. It is a packing for preventing noise, which is interposed between 11 and 11.

The thus constructed device is provided at a side groove, a transverse groove (not shown) or the upper edge of the opening of the water collecting basin, and when used in the same manner as a conventional groove lid device of this kind, the lateral member 14 of the groove lid 11 is provided. The rainwater is properly discharged from the gap between the holes 14 and 14, and the groove and the mouth are accurately closed to ensure safety, but the upper edge of the end plate 12 has a short brim 15 having an arcuate edge 15a. Between the inner side surface of the receiving frame member 1 and the end plate 12 of the groove lid 11, since the arcuate edge 15a is brought close to the inner side surface of the vertical plate portion 1a of the receiving frame member 1. Even when the groove 21 is designed so that a required gap 21 can be formed so that the groove lid 11 can be fitted easily, the gap 21 is miniaturized by the short brim portion 15 at the upper end, and it is difficult for sand and sand to enter the gap 21. The opening and closing of the groove lid 11 does not become difficult. However, since the edge of the short brim portion 15 is an arcuate edge 15a, the short brim portion 15 having the arcuate edge 15a also has the effect of preventing the loader from tripping the snow to scrape snow. Therefore, even if it rusts with the inner surface of the receiving frame material 1, there is very little contact area even if rust occurs, so if the groove lid 11 is pulled up with normal force, it will easily rust. The lid can be opened and the lid can be opened.

Further, if the present invention is adopted in a system in which a leaf spring metal fitting is interposed between the inner side surface of the receiving frame member 1 and the end plate 12 of the groove lid 11 in order to prevent noise from being generated when the vehicle is traveling. Even if a large lateral load is applied, the arcuate edge 15a of the short brim portion 15 comes into contact with the inner side surface of the receiving frame member 1 before reaching the limit of damage to the leaf spring metal fittings, so that the leaf spring metal fittings are not damaged for a long time. It will be durable.

Further, as described in the embodiment, the lower surface of the short brim portion 15 is formed in the upward inclined surface 15b, or the interior angle of the L-shaped receiving frame member 1 is larger than 90 ° and the end plate 12 and the receiving frame. If the gap 21 between the material 1 and the vertical plate portion 1a is widened upward, fitting of the groove lid 1 to the receiving frame material 1 becomes easier, which is preferable. Furthermore, when the packing 16 is interposed between the bottom plate portion 1b of the receiving frame material 1 and the groove lid 11, a noise prevention effect can be expected.

[0011]

[Effect of device]

 As will be apparent from the above description, the present invention is a groove lid device in which a groove lid is fitted and supported on a receiving frame member having an L-shaped cross section, and the tip of the end plate of the groove lid is formed as an arcuate edge. Since the short brim portion is integrally stretched, a large gap is not formed between the inner surface of the receiving frame material and the end plate of the groove lid. It is possible to completely prevent the lid from becoming difficult to open and close, the safety is improved by the arcuate edge, there is no tripping of the loader for snow scraping, and the inner surface of the receiving frame material is also a noise countermeasure. In the method of interposing a leaf spring metal fitting between the end plate and the end plate of the groove lid, the short brim portion acts as a stopper even if a large lateral load is applied, so the leaf spring metal fitting is damaged by an excessive lateral load. To prevent long-term use There is an advantage. Therefore, the present invention is of great practical value as a groove lid device that solves the conventional problems.
