Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a connecting fitting for connecting adjacent gratings of gratings used for various purposes such as being attached to side gutters.

<Prior Art> In order to connect adjacent gratings and hold them without wobbling or to prevent the gratings from being stolen, it is necessary to fix the gratings. By the way, when fixing the grating, it may not be possible to fix the grating to the loading shelf at its end.

Another fixing means in this case is a method of connecting adjacent gratings to each other. As shown in FIG. 5, a conventional connecting fitting x used in such a method has a generally rectangular cross section with an elastic opening y formed at its lower part and consisting of a pair of curved pieces that expand outward. , is externally fitted across the two outermost bearing bars 2a, 2a of the adjacent gratings 1, 1 from above by the expansion operation of the elastic opening y, and surrounds the bearing bars 2a, 2a, and its side plate part. The bearing bar pair is sandwiched between z and z.

<Problems to be solved by the invention> The dimensions of the grating are set taking into account the forming error and the construction error of the groove length. For example, if the installation size is 1 m, the grating is designed in advance to have a length of 995 mm. Close the lid,
This is because if the length corresponds directly to the set dimensions, a fatal problem will occur in which the last piece cannot be attached to the groove path due to molding errors. In order to neatly lay the gratings on the groove path while taking into consideration the short length of the gratings, when attaching each grating, the gratings are not placed in close contact with each other, but a gap m is created as shown in FIG. 5.

In this way, since there is a gap m between each grating, in the conventional configuration described above, this gap m
This allows the bearing bars 2a, 2a to move in the direction of the arrow α within the connecting fitting x, and since no elastic force is applied by the side plates z, z, there is a drawback that their retention is insufficient. Ta.

The object of the present invention is to provide a grating connection fitting that does not have the above-mentioned drawbacks.

<Means for Solving the Problems> The present invention provides an inverted U-shaped envelope that is fitted from above over at least two adjacent outermost bearing bars of gratings that are laid adjacent to each other on the left and right. an elastic pressure welding end coupled to both lower ends of the enclosing part and disposed between the bearing bars of each grating and contacting the inward surface of the outer bearing bar; It is characterized by comprising a tongue-shaped holding piece having an elastic pressure contact end that comes into contact with the holding piece.

<Function> Between the outer bearing bar of each grating and the adjacent bearing bar on the inner side,
Tongue-shaped holding pieces connected to the left and right sides of the connecting fittings are fitted from above, and their inward and outward surfaces are pressed against elastic press-contact ends provided on the tongue-like holding pieces, respectively.

Each grating is tightly attached by the urging force in the inner and outer directions.

Therefore, adjacent gratings are restrained from moving inwardly and outwardly.

<Example> In Figs. 1 to 4, 1 indicates a grating, which has a rectangular plate shape in which bearing bars 2 are arranged in parallel at regular intervals, and each is connected by a twist bar 3 perpendicular to the above. . When the gratings 1 are attached to a side gutter, for example, a large number of the gratings 1 are arranged in rows on the gutter while creating gaps m between each grating 1.

Reference numeral 10 denotes a connecting fitting according to the present invention, which has a U-shape and is fitted from above over the two outermost bearing bars 2a, 2a of the gratings 1, 1 which are laid adjacent to each other. It has a shaped enclosing part 11, and tongue-shaped holding pieces 12, 12 connected to both lower ends thereof and arranged between bearing bars 2a, 2b of each grating 1, 1. In addition, the connecting fitting 1
0 has two hook pieces 14, 1 having an outer fitting groove 13 that fits into the twist bar 3 from below.
4 is formed.

The tongue-like holding pieces 12, 12 have a gap between their inner and outer edges larger than a gap between the opposing bearing bars 2a, 2b of each grating 1, and their inner edges contact the inward surface 4 of the bearing bar 2a. It has an elastic pressure contact end 15, and an elastic pressure contact end 16 whose outer edge is pressed against the outward facing surface 5 of the bearing bar 2b.

The procedure for attaching the connecting fitting 10 will be explained.

First, the adjacent gratings 1, 1 are brought close to each other, and then the connecting fitting 10 is inclined with respect to the grating 1, and the adjacent bearing bars 2a, 2a are
The wrapping part 11 is externally fitted to the hook pieces 14, 14.
After hooking the outer fitting grooves 13, 13 on the twist bar 3 as shown by the chain lines in FIG. 3, the tongue-shaped holding piece 12 is press-fitted between the bearing bars 2a, 2b. So,
As shown in the solid line in FIG. 3 and in FIG. 4, the tongue-shaped holding piece 12 is located between the bearing bars 2a and 2b,
The elastic press contact end 15 of the tongue-shaped holding piece 12 presses against the inward facing surface 4 of the bearing bar 2a, and the elastic press contact end 16 press against the outward facing surface 5 of the bearing bar 2b. Therefore, the elastic press ends 15 and 16 contract slightly and come into elastic contact with the inward surface 4 and the outward surface 5.

In this installed state, the grating 1
is restrained from moving in the left-right direction by the elastic contact between the elastic press-contact ends 15 and 16, and is held immovable. Furthermore, a gap m between each grating 1 is defined by the elastic press-contact ends 15, 15.

In the embodiment described above, the enclosing portion 11 may have a wide configuration in which two or more bearing bars 2 can be fitted onto the outside.

In the above embodiment, the gap m between the adjacent gratings 1, 1 is defined by the elastic pressure contact ends 15, 15. Variations in the dimensions of each grating 1 can be accumulated between the gratings placed at the end, and this can be eliminated by taking measures such as omitting the connecting fittings at that position and narrowing the gap m. Since it can be absorbed, there is no problem in adhesion of the grating 1.

<Effects of the invention> As described above, the present invention forms the enclosing part 11 in the connecting fitting 10, and also provides a pair of left and right elastic press-contact ends 15, 16, and the press-contact ends 15:
holding the inward surface 4 of the bearing bar 2 to prevent the gratings 1, 1 from moving in the direction of separation;
Furthermore, the pressure contact ends 16 hold the outward facing surface 5 to prevent the gratings 1, 1 from moving in the approaching direction, and the pressure contact ends 15, 16 are provided with elasticity to sandwich the bearing bar 2. The holding is performed stably without wobbling, and the connecting fitting 10 cannot be easily removed upward after the bearing bar 2 of the enveloping portion 11 is fitted onto the outside. For this reason, when laying grating 1 continuously, each grating 1, 1
By connecting them to each other, their alignment can be maintained, and since the grating 1 cannot be easily removed, theft can be prevented.
There are excellent effects such as being able to maintain the installation of the grating 1.
