  In the first place, it is a matter of course that the groove cover for the side groove provided to ensure the passage of cars and people must have sufficient strength so that no problems occur even if the car or person rides on it. It is. Conventionally, on the premise of such a viewpoint, it has been considered how to reduce the labor of the worker at the time of attachment / detachment while ensuring the strength of traffic of cars and people. Therefore, for example, there is a limit to reducing the material, and the grating material constituting the grating has to be thick. Further, due to the nature of such a groove lid, it is necessary to provide a receiving portion for receiving the groove lid in the side groove.

  However, for example, at least on roads and slopes where there is no need to consider driving, such as promenades, slope steps or shoulders laid in forests where there is little traffic, It is not necessary to use a high strength groove cover manufactured as a premise. On the other hand, although there is little traffic, the time interval for cleaning is widened, and it is often found that the groove lid is difficult to remove due to dust and the like being stuck at the contact portion between the groove lid and the side groove during cleaning. Especially in the forest and on the vegetation slope, fallen leaves and gravel are likely to collect in the abutment between the gutter lid and the gutter and in the gutter, and it was manufactured on the assumption that it would be used for a gutter on a general road in such an environment. Using a groove lid, the groove lid has more weight than the benefits gained from ensuring the high strength of the groove lid, and the groove lid is fixedly attached to the receiving part of the side groove. The disadvantage is that it is inefficient due to the labor required for the removal work.

  An object of the present invention is to provide a groove cover for a side groove that is suitable for a side groove provided at a place where it is not necessary to consider at least the passage of a vehicle.

  Therefore, the present inventor has invented the following invention as a groove cover disposed in a side groove such as a promenade, a slope step or a shoulder portion laid in a forest.

That is, the invention according to claim 1

In one of the two edges extending in the groove width direction of the upper Kimizofuta is for groove, characterized in that the hook-shaped connecting portion is provided to be applied to the groove closure adjacent to the coupling grooves lid adjacent grooves It is a lid.

  Basically, a strong and light wire rod is used as the mesh member constituting the groove cover for the side groove according to the present invention. However, the nature or environment of the side groove, that is, the side groove width, the road where the side groove is provided, etc. It is preferable to select the material and thickness of the wire according to whether or not it is frequent.

(1) In the invention according to claim 1, the groove cover is supported on the road surface by the support part protruding to the side of the groove cover for the side groove, and the groove cover is regulated so as not to be detached from the side groove by the restriction part protruding downward. Therefore, it can be used without a receiving part in the side groove.

Further, a plurality of vertical lines gutter grooves lid extending groove longitudinally, is constituted by a mesh member formed by a plurality of horizontal lines extending to cross the vertical line groove width direction, gutter of the mesh member On each of both side portions extending in the longitudinal direction, the horizontal line is bent and protrudes downward and is inserted into a side groove to form a restriction portion for restricting movement of the groove lid in the side groove width direction. In the place where the restriction part is not provided, the horizontal line protrudes to the side of the side groove without being bent, and a support part for supporting the groove cover is formed by being grounded to the road surface. Work is easy.

  Furthermore, compared with the conventional grating, member cost becomes significantly cheaper.

(2) In the invention according to claim 2, the horizontal line is provided on the upper side of the vertical line, and the horizontal line is located below the vertical line at a plurality of locations on both sides extending in the longitudinal direction of the side groove of the mesh member. The above-mentioned restricting portion that is bent to the opposite side is formed in a vertical cross-section C shape , and the opposing restricting portion elastically abuts on both side walls of the side groove so that it can be easily detached even when receiving some external force. There is no.

Moreover, a mesh is formed on the vertical line arranged in the longitudinal direction of the side groove, crossing the horizontal line in the lateral groove width direction so as to intersect with these, and the fallen leaves and the like deposited on the groove cover for the side groove are Since it can be removed simply by lifting the lid and tilting it in the lateral groove width direction or by sweeping it smoothly in the lateral groove width direction, unnecessary objects on the groove lid can be easily removed.

(3) In the invention according to claim 3 , since the hook-shaped connecting portion provided on one of both edges extending in the side groove width direction of the side groove groove cover is hooked on the adjacent groove cover, the groove cover for each side groove is connected to each other. Can be easily connected.

  Embodiments of the groove cover for side grooves according to the present invention will be specifically described below with reference to the drawings.

  First, FIG. 1 is an explanatory view showing a state in which a gutter 5 is provided in each of the slope shoulder 2, slope slope 3 and promenade 4 of the vegetation slope 1. The groove cover for a side groove according to the present invention is used as a groove cover for the side groove 5 provided at least in a place where it is not necessary to consider the passage of a vehicle as clearly shown in the three side grooves 5 shown in FIG. Is.

  Next, the structure of the groove cover for side grooves according to the present invention will be described with reference to FIG.

  Here, nine vertical lines 6 and 51 horizontal lines 7 are orthogonal to each other, and a wire mesh formed by welding each intersection is used as a mesh member to constitute a groove lid. The mesh member may be formed using a synthetic resin in addition to the metal mesh.

  As the wire, it is preferable to use a light and strong wire that is not easily rusted. For example, a galvanized iron wire is preferable in the case of a metal wire.

  The thickness of the wire is 6 mm or less, more preferably 3 mm or less in consideration of the convenience in handling the groove lid. However, this point is determined by determining the properties expected of the groove cover for the side groove from the material of the mesh member and the environment surrounding the side groove 5. For example, in the case of a resin-made mesh member, a light groove cover can be manufactured even if a wire rod formed thicker than in the case of a wire mesh is used, so that the convenience in handling is not impaired even if a thick wire rod is used. In addition, in the case of the groove cover of the side groove 5 provided on the road through which a general pedestrian passes to some extent, it is assumed that a person gets on, so it is manufactured with sufficient strength with a thick wire, If it is a groove cover of the side groove 5 provided on a path or the like that is allowed only for the personnel, it is possible to alert each worker during the passage, so it is not necessary to give so high strength, and the thin wire rod Is acceptable.

As shown in FIG. 3, the mesh member is knitted on a plurality of vertical lines 6 arranged in parallel to the side groove longitudinal direction L and a plurality of horizontal lines 7 in the side groove width direction W so as to intersect perpendicularly with them. It is preferable to knit in the form of handing over. The size of each mesh may be such that the fallen leaves do not pass through the mesh and fall into the side grooves 5 .

Sign-8 is a support portion which projects from both edges extending in the groove longitudinal direction L of Mizofuta body sideways, and is grounded on the road surface to support the Mizofuta body.

  Reference numeral 9 denotes a restricting portion that protrudes downward from both edges extending in the side groove longitudinal direction L of the groove lid main body and is inserted into the side groove 5 to restrict the movement of the groove lid in the side groove width direction W. The restricting portion 9 may be formed so that the restricting portions 9 are parallel to each other in the longitudinal section, but more preferably, as shown in FIG. In a free state, it is formed so as to become wider as it goes downward. In FIG. 5, the degree of opening of each restricting portion 9 to the outside is x = 93 °, but this point is appropriately adjusted in relation to the external force applied to the groove lid. When both restricting portions 9 are formed to have a vertical cross-sectional shape, the groove cover for the side groove is pushed into the side groove 5 so as to be pushed in from above, and each restricting portion 9 is inserted into the side groove 5 as shown in FIG. It installs so that it may contact | abut to each side wall elastically.

  In addition, as shown in FIG. 7, the support part 8 and the control part 9 may be provided so that the support part 8 comes inside the control part 9 provided at two places on each edge extending in the lateral groove longitudinal direction L. Good. Alternatively, a plurality of locations may be provided on each edge extending in the lateral groove longitudinal direction L.

  Reference numeral 10 denotes a hook-shaped connecting portion for connecting adjacent groove cover for side grooves. The hook-shaped connecting portion 10 may be manufactured separately from the groove lid body and attached later, or the vertical line 6 of the groove lid body is extended in the side groove longitudinal direction L, and the tip thereof is bent into a hook shape. May be. And as shown in FIG. 8, it hooks on the horizontal line 7 of the groove cover for another side groove adjacent, and connects each other groove cover. It is preferable that two or more hook-shaped connecting portions 10 are provided on the integral side groove cover.

  In addition, when not providing the hook-shaped connection part 10 in a groove lid, as a method of connecting adjacent groove lids, the method of bundling the horizontal lines 7 which mutually contact | abutted using the annular clip etc. is mentioned.

  The present invention employs the above-described structure with respect to the groove cover for the side groove, so that it can be used even if the side groove 5 has no receiving portion, and does not easily come off from the side groove 5, while the work of attaching and removing becomes easy. It is useful for use as a groove cover for the side groove 5 provided at least in places where it is not necessary to consider the passage of a car, such as a promenade, a slope step or a shoulder portion laid in the forest. is there. Further, since the groove lid is formed by using a mesh member, the manufacturing cost is low and it is economical.
