Description

[Detailed Description of the Invention] The present invention relates to a device for fixing a lattice-shaped groove cover or the like to a receiving frame.

Conventionally, grid-like groove covers (also called gratings) made of metal plates used for road cross-cutting grooves, etc. have been fitted with a receiving frame to prevent rattling and sideways sliding as vehicles pass over the groove cover. Although they are fixed using bolts, nuts, etc., gutter covers installed on side gutters are usually simply placed on a receiving frame because vehicles and the like rarely pass over the gutter covers.

In recent years, gutter covers installed on side gutters, etc.
To prevent rattling when a vehicle passes by, and to prevent metal gutter covers from expanding and contracting due to changes in temperature, a small gap is provided between the gutter covers to prevent the gutter covers from moving when a vehicle passes by. In some cases, the gap becomes wide or the grooves come into close contact with each other, and in order to prevent this displacement, it has become desirable to fix the groove cover to the receiving frame.

In order to meet these demands, various fixing devices have been used, such as attaching protrusions or springs to the groove cover or receiver frame, or inserting rubber plates, etc. Although the lid does not easily come off easily, it is difficult to process, and in the case of a clip type device with a spring on the outside attached to the side plate of the groove lid, that is, the fixing device 11 as shown in FIG. If a force is applied to lift the groove upward or a force is applied in the direction of flow of the groove, the groove cover 6 may lift up or shift, leaving the fixing device 11 behind, or the fixing device 1 as shown in FIG.
Similarly, in the case of 1', there was a drawback that the groove cover 6 floated up and down while the fixing device 11' was attached.

In order to meet these demands, the present invention is an improved clip-type fixing device, and will be described below with reference to embodiments shown in the drawings.

As shown in Fig. 1, the present invention consists of a narrow strip made of elastic metal formed into a U-shape, which is latched on both sides of one side strip end 4 in parallel to the strip of the clip 2. This is a fixture 11, such as a groove cover, in which pieces 3, 3 are arranged side by side in an H-shape, and the upper ends of the locking pieces 3, 3 are bent outward and the lower ends are bent inward.

Since the present invention is constructed as described above, it is used by being attached to the side plate 7 at at least the four corners of the groove cover 6 such as a grating as shown in FIG.
As shown in FIGS. 3 and 4, the fixture 1 is fixed to the side plate 7 of the groove cover 6 with two clips so that the locking pieces 3, 3 are located between the groove cover 6 and the receiving frame 9. be done. When clamping the fixture 1, the tips of the locking pieces 3, 3 are bent outward, so it is easy to insert and fit, and when clamped, the lower ends of the locking pieces 3, 3 are bent inward. Since it is bent, there is no fear that the locking pieces 3, 3 will bite into the side plate 7 of the groove lid and fall off due to their elasticity. Furthermore, when placing the groove cover 6 on the receiving frame 9, the lower ends of the locking pieces 3, 3 of the fixture 1 are bent inward and are in contact with the side plate 7 of the groove cover 6, so that the groove cover 6 can be easily placed on the receiving frame 9. It can be inserted and placed, and since the upper ends of the locking pieces 3, 3 are bent outward, the elasticity of the locking pieces 3, 3 can be used to press the locking pieces 3, 3 so as to bite into the inner surface of the receiving frame 9. Since the gutter cover is fixed in place, even when a vehicle or the like passes over the gutter cover, there is no fear that the gutter cover will float up and generate a rattling sound, or that it will shift and cause lopsidedness.

In addition, since it can be manufactured by punching and forming an elastic metal plate, it can be provided at a low cost.
