Abstract

(57) [Summary] [Purpose] The purpose is to provide a groove cover that does not generate rattling noise and has a connecting mechanism. [Structure] The groove cover that forms the main unit has an isosceles triangular shape, and at the top formed by two equal sides, contact legs are provided on the back surface, and locking grooves that open on both sides are formed on the front surface in an inverted L shape or The groove of the sub-unit body is formed in a Z-shape, and has locking sides that are substantially the same shape as the locking groove protruding from both ends of the bottom side, and is positioned at both ends of the groove cover of the main unit body. The lid has a right triangular shape divided into two equal parts by a line connecting the center of the top and bottom of the groove lid of the main unit, and is configured so that contact legs are also provided at the top of the right angle.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a gutter cover that can be installed on road side ditches, cross ditches, drainage ditches in parking lots, etc. For more details, the applicant has filed an application as Utility Model Publication No. 61-2213. This relates to improvements to gutter covers that have been announced and registered.

0002

[Conventional technology]

Traditionally, gutter covers installed on roadside gutters have been made of stainless steel plates etc. in the form of strips. Gratings, which are cut into pieces and assembled into a lattice pattern, are widely used to prevent vehicles from passing. In many places, it is fixed to the receiving frame with bolts and nuts, etc., so that there is no wobbling. It was common.

0003 However, when gratings are assembled by welding, the welds peel off and form into strips. flat steel plates may bend, so the applicant uses cast iron, which has good pressure resistance, to By manufacturing the groove cover separately into isosceles triangular units, it is durable and does not rattle. Provide a groove cover and also contact the back side of each vertex as seen in Publication No. 61-2213. When the legs are installed vertically and the groove cover is connected, a bolt insertion hole is provided in the contact leg that meets the bolt. We provide groove covers that are configured to connect the groove covers by connecting them with nuts, and have a wide It is widely used.

0004

[Problem that the idea aims to solve]

As mentioned above, the applicant of the present application has the We have provided groove covers for connections such as this, but bolts and nuts are used for connection. Therefore, it is desirable to be able to easily remove it in places where cleaning is done inside the grooves. I'm starting to be able to do it.

[0005] Also, when they are installed consecutively, there is no wobbling due to the three-point support, but pebbles may fall under the leg pieces. If they were caught, a difference in level could occur between the groove lid and the adjacent groove cover.

[0006] The present invention provides a groove cover that is easy to connect, does not create a step, and does not rattle. The purpose is to

[0007]

[Means to solve the problem]

The groove cover of the main unit is shaped like an isosceles triangle, and the top formed by two equal sides is In addition to providing contact legs, the bottom supports both ends and locks when connected. This problem was solved by configuring the system so that

[0008] In other words, the groove cover of the main unit has an isosceles triangular shape, with two equal sides forming A contact leg is provided on the back side of the top part, and a locking groove that opens on both sides is provided on the surface. , with locking pieces protruding from both ends of the bottom that have the same shape as the locking groove formed on the top. be.

[0009] In addition, the groove covers of the sub unit body located at both ends of the continuous groove cover of the main unit body are The groove cover of the body is divided into two equal parts by a line connecting the center of the top and the bottom, making it a right triangle shape. Contact legs are also provided on the top of the corner.

0010 The gutter cover is made of cast iron and has drainage holes formed over its entire surface.

[0011]

[Effect]

The groove cover of the present invention is suspended on stepped receiving frames provided at the upper ends of both side walls of the groove. The groove cover, which forms the main unit, is fitted and locked at the top, and the necessary parts are sequentially installed. The groove cover of the sub-unit in the shape of a right triangle is similarly connected at both ends. It will be done.

0012

【Example】

The present invention will be explained according to the embodiment shown in the drawings. has an isosceles triangular shape as shown in Figure 1, and the apex (3) formed by two equal sides As shown in Figure 2, a contact leg (7) is provided on the bottom surface that contacts the receiving frame of the groove, and the surface is provided with locking grooves (6) that open on both sides, and at both ends of the bottom, as shown in Figures 1 and 2. At both ends of the base (4), that is, at the top formed by two equal sides and the base, at the top (3) Attach locking pieces (5) that have almost the same shape as the locking groove (6) provided on two equal sides along the bottom (4). It can be installed protrudingly.

[0013] In addition, the groove cover (2) forming the sub-unit body is attached to the top part (3) of the groove cover (1) of the main unit body as shown in Figure 1. ) and the center of the base (4) divides the shape into two equal parts, with the top making a right angle. A contact leg (8) is also provided at the bottom.

[0014] The locking grooves (6) provided at the top of the groove covers (1) and (2) are as shown in Figures 2 and 3. It has an inverted L-shape with an opening on the side so that the surfaces are flush when installed in a row. However, in order to prevent the locking piece from floating further, it forms a Z-shape from the side as shown in Figure 4. It is best to form a locking groove (6´) like this, in which case it is protruding from both ends of the bottom of the groove cover. The locking piece (4') has a Z-shape and is shaped to fit into the locking groove (6').

[0015] The top (3) of the groove cover (1) is a trapezoid with a triangular tip cut out as shown in Figures 1 and 2. It may have a shape, or it may have a shape with a rectangular protrusion protruding from it. The gutter cover is cast from cast iron, and although only one part is shown in the drawing, there are through holes throughout the entire surface. I get kicked.

[0016]

[Effect of the idea]

Since the gutter cover of the present invention is constructed as described above, it can be accessed from one side or from the installation location. From the center, fit and lock the locking piece of the adjacent groove cover into the locking groove of the groove cover and connect them. However, the groove cover of the main unit is an isosceles triangle, and the groove is closed only at the top formed by two equal sides. It is in contact with the receiving frame and carries locking pieces protruding from both ends of the bottom of the groove cover adjacent to the top. Since each groove cover is supported at three points, there is no rattling and no stones are caught between the contact legs. This eliminates the risk of creating a level difference with the adjacent gutter cover even if the height is increased due to It is something that has fruit.
