Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a gutter cover for covering road side gutters, etc., and in particular relates to an improved gutter cover with an improved attachment part for attaching the gutter cover main body to the receiving frame. .

<Prior art> The gutter cover body originally performs its function simply by placing it in the receiving frame, but it gradually moves during long-term use, creating a large gap between the gutter cover bodies, which is dangerous for walking. The gutter cover body collides with the receiving frame each time a vehicle passes by, causing rattling and noise. In order to prevent this, conventionally,
As disclosed in Japanese Patent No. 46691, the four joints of the gutter cover body were directly fixed to the receiving frame with bolts.

<Problems to be Solved by the Invention> However, in the conventional method of installing the gutter cover body as described above, each bolt had to be completely removed in order to clean the side gutter, which was troublesome. In particular, when it is necessary to remove a large number of gutter cover bodies from the gutter at the same time, the number of bolts to be removed becomes extremely large, making the removal work extremely troublesome.
There was a problem that the removed bolts had to be used to re-fasten the gutter cover body, so they had to be stored so that they would not be lost.This invention solves the drawbacks and problems of the conventional gutter cover as mentioned above. The purpose of the present invention is to provide a groove cover that eliminates the problem.

<Means for solving the problem> The gutter cover according to this invention includes receiving frames provided along both edges of the gutter, and a gutter cover body fitted and supported between these receiving frames. There is. A recess is formed at a suitable position in the portion of the groove cover body located on the receiving frame, and the bottom of the recess is formed with step portions facing each other at a predetermined interval. In addition, a holding metal fitting that is longer in length than the distance between the step portions and narrower in width than the distance between the step portions is arranged so as to straddle the step portions when the groove cover main body is fixed. A bolt fixed to the support frame passes through the presser metal fitting. A nut for tightening the presser fitting is threaded onto the bolt, and a nut stopper is provided at the tip of the bolt to prevent the nut from coming off.

<Function> In the groove cover of this invention, the groove cover body is fixed to the receiving frame by arranging the presser fitting so as to straddle the steps of the groove cover body and tightening the nut.
When removing the groove cover main body, loosen the nut a little to the extent that the presser metal fitting can rotate freely, and rotate the presser metal fitting approximately 90 degrees from the state in which it straddled the stepped portions when tightened. Since the width of the holding metal fitting is made narrower than the interval between the steps, the holding fitting does not come into contact with the stepped parts at all, and the groove cover body can be removed from the receiving frame. In this case, the tip of the bolt is Since a nut stop is provided, the nut will not be unnecessarily removed from the bolt, and there is no fear of losing the nut.

<Example> Hereinafter, the gutter cover according to this invention will be explained with reference to the illustrated example. In Fig. 1, reference numeral 2 denotes a so-called lattice-type gutter cover body, and the gutter cover body 2 is fitted and supported between L-shaped angle receiving frames 4 provided along both edges of the side gutter. There is. The L-shaped angle of the receiving frame is fixed by anchors 6, 6, . Second
As shown in the enlarged diagrams and FIG.
Recesses 8, 8... for mounting are formed on both sides,
At the bottom thereof, facing steps 10, 1 at a constant interval are provided.
0 is formed. The receiving frames 4, 4 have recesses 8, 8
Cross recessed round head bolt 1 at the position corresponding to...
2, 12, etc. are installed in an upright manner, and their lower ends are screwed into a nut 14 that is previously fixed to the back surface of the receiving frame 4 by welding 16, and furthermore, both are fixed by welding.

A spring washer 18 is fitted into the bolt 12, and presser fittings 20, 20...
It is arranged so as to straddle 0 and 10. As shown in an enlarged view in FIG. 2, the presser metal fitting 20 has an oval or elliptical planar shape, and its length (longer diameter side) is the same as that of the stepped portions 10 and 10 as described above.
longer than the distance A between the stepped portions so as to straddle the gap,
Its width (shorter diameter side) B is slightly narrower than the above-mentioned distance A. The center portion of the presser metal fitting 20 is bent downward, and its tip abuts against the spring washer 18.
The cross-recessed round head 26 of the bolt 12 acts as a nut stopper to prevent the nut 22 from coming off completely.

To fix the groove cover body 2 on the receiving frames 4, 4, loosen the nuts 22, 22... and the presser metal fittings 20, 20
... are pushed up by the action of the spring washers 18, 18.... In this state, as shown by the imaginary line in FIG.
10, and insert the bolts 12, 1 into the center of the groove cover body 2 in the recesses 8, 8...
2... is placed on the receiving frames 4, 4.
At this time, the bottom surfaces of the presser fittings 20, 20, . Here, presser metal fitting 2
0, 20... respectively by 90 degrees to the position where they straddle the stepped portions 10, 10 as shown in the figure, and tighten the nuts 22, 22..., the presser metal fittings 20, 2 will be removed.
0... holds down the step portions 10, 10, and the groove cover main body 2 is fixed on the receiving frames 4, 4.

When removing the groove cover main body 2 from the receiving frames 4, 4, loosen the nuts 22, 22, contrary to the fixing described above, and move the presser metal fitting 20 from the fixed position shown by the solid line in FIG. 2 to the position shown by the imaginary line. Rotate it 90 degrees. Since the width B of the presser fitting 20 is shorter than the distance A between the stepped portions 10, 10, it can be removed from the receiving frames 4, 4 by lifting the groove cover main body 2. In this case, since the nut 22 is prevented from coming off by the nut stopper 26, the groove cover main body can be removed by simply rotating the presser metal fitting 20 by 90 degrees without removing the nut from the bolt. By mistake, Natsu 2
2 will never be removed, and loss of the nut is therefore completely prevented.

In the above embodiment, the nut 14 is welded to the back side of the receiving frame 4 in advance, and the round head bolt 12 is attached to this.
In addition to this, insert a normal hexagonal head bolt from the back of the receiving frame to the front, weld the hexagonal head to the receiving frame 4, and attach a washer 18 and a holding metal fitting 20 to the bolt. After each is installed, the nuts 22 may be screwed together, and a suitably shaped nut stopper may be welded to the upper end of the bolt, or a cotter pin may simply be inserted into the tip of the bolt. Note that the spring washer 18 is attached to the presser metal fitting 20 when the nut 22 is loosened.
Since the presser metal fitting 20 is pushed up so that the lower surface is located above the upper surface of the stepped portions 10, 10, when attaching the groove cover body, you can simply rotate the presser metal fitting 20 by 90 degrees without lifting it by hand. It's nice and convenient, but it's not necessarily necessary for the purpose of this invention.

<Effects> As described above, according to this invention, simply loosening the bolt and rotating the presser metal fitting 20 by 90 degrees will remove the stepped portion 1.
The groove cover main body 2 can be removed from the receiving frame by simply making sure that it does not engage with the groove parts 0 and 10. Conversely, when fixing the groove cover main body to the receiving frame, align the presser metal fittings in a direction in which they do not engage with the stepped portions. It is only necessary to place the groove cover main body at a predetermined position on the receiving frame in this state, rotate the presser metal fitting 90 degrees, and tighten the nut 22, which simplifies the attachment and detachment work of the groove cover main body. Furthermore, according to this invention, since the nut stopper 26 is provided,
This prevents the nut from being removed from the bolt by mistake, and completely prevents the accident of losing not only the nut but also the retaining metal fitting when removing the groove cover body 2 for cleaning or the like. can.
