JPS5814923B2 - Parallel connector for rod-shaped bodies - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector for connecting a large number of rod-like bodies such as pipes and rods in parallel.

For example, shelves and fences formed by aluminum pipes, grids and fences formed by iron bars, etc. require a large number of rod-shaped bodies to be connected and fixed in parallel.

In such cases, connecting plates are usually applied from both sides of the rod-like bodies, and the connecting plates are screwed together between each rod-like body, or the connecting plates are directly welded to the connecting plates (or crossbars) to fix the connection.

If welding is not used due to low work efficiency due to welding or the material is difficult to weld, screws will be used, but if there are many rod-shaped objects, the number of screws will increase accordingly, reducing work efficiency. As this decreases, appearance also worsens.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector that requires fewer screws and that can securely connect a large number of rod-shaped bodies at once.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the connector 10 of the present invention is formed by a combination of two connecting plates 11 and 11' having the same structure.

The connecting plate 11 is formed into an elongated shape, and a plurality of bent pieces 12 are formed on one side of the connecting plate 11 at regular intervals by cutting and bending.

At both ends of the connecting plate 11, connecting pieces 13 and 13 are provided which are bent into an L shape in the same direction as the bent pieces 12, respectively.

The bent piece 12 protrudes approximately to the height of the connecting piece 13, 13', and has a curved surface 14 formed along the outer periphery of the pipe A to be connected at its upper end.

The structure of the connecting plate 11' is the same as the connecting plate 11 described above,
It is assembled with the front and back reversed.

As shown in FIG. 2, the bent piece 12 is formed so that its curved surface portion 14 contacts the connecting plate 11.11 on the opposite side.

However, this curved surface portion 14 is at least connected to the opposite connecting plate 11.
11, that is, in the case of the bent piece 12 standing up from the connecting plate 11, the curved part 14 is formed closer to the connecting plate 11 than the center of the pipe A, and the bent piece of the connecting plate 11 12 may also be formed in the same manner.

In order to connect the pipes A by the above-mentioned connecting plates 11.11, as shown in FIG.
2, place the connecting plate 11 on top of it, and pull both in opposite directions as shown by the arrows in Figure 2.
Pipe A has bent surface portions 1 of bent pieces 12 facing each other.
4.

Then, tighten the connecting pieces 13, 13 with the screw 15,
Join both connecting pieces 13.13.

In the illustrated case, one coupling piece 13 has a screw hole 16 formed therein, and the other coupling piece 13' has a hole 17 into which a screw 15 is loosely fitted.
are provided, and are stacked so that the connecting piece 13 is on the inside and the connecting piece 13' is on the outside.

Therefore, if the pipe A is held between the bending pieces 12 as described above and each screw 15 is tightened, the pipe A will be held between the bending pieces 12.
Support is fixed between 2.

Note that the above-mentioned connecting pieces 13 and 13' are connected to the connecting plates 11 and 11.
It is not necessarily necessary to provide it at both ends, and it may be provided only at one end.

FIG. 3 shows a pipe shelf constructed by connecting the pipes A in parallel as described above.

In this case, it is desirable to provide the upper connecting plate 11 with a side plate 18 for overturning the ends so that the ends of the pipe A are not exposed at both ends (see FIG. 4).

Further, if the pipe A is long, the middle part of the pipe A may be connected by the above-mentioned connecting plate 11.11.

The above shows an example in which the connecting device of the present invention is applied to a pipe shelf, but FIG. This shows the state in which the

In this case, one set of connectors 10 is used for each appropriate number of vertical beams B.

In each of the above embodiments, the bending shape of the bending piece 12 is determined depending on the shape of the rod-like body such as the pipe A and the length and breadth B.

Therefore, if the rod-shaped body is square, the curved surface portion 14 is formed in a square shape.

Further, instead of forming the above-mentioned bending piece 12 by cutting and raising the connecting plate 11, 11', it may be directly attached by welding.

As described above, when connecting a plurality of rod-like bodies in parallel as a set, the connecting tool of the present invention clamps each rod-like body between the curved surfaces of the bending pieces facing each other, so that it is difficult to fix the rod-like bodies. Since it is only necessary to connect the connecting plates to each other, the number of screws required is extremely small, which has the effect of significantly improving the work efficiency of screw tightening.

Also, since there are fewer screws, it looks good and is safe.

In addition, as long as the connecting plates are connected reliably, each rod-like body is supported and fixed by the bent piece, so there is an effect that the connection is ensured.

Furthermore, since the bending pieces are formed by cutting and raising the connecting plates, the bending pieces that support each rod-shaped body and the connecting plates that connect each bending piece can be constructed as one piece, and both connecting plates By relatively moving the rods in the length direction, the distance between the bent pieces changes, so rod-shaped bodies of various diameters can be accommodated.
