Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical cable and an I cable.
The present invention relates to an assembling drum used for winding lightweight electric wires and cables such as V and OW.

[0002]

2. Description of the Related Art Conventionally, electric wires and cables such as optical cables, IVs, and OWs have been wound on wooden drums or plastic drums, and thus have the following problems.

It is difficult to dispose of used drums. Takes place for storage because it is bulky. Being bulky, transportation costs are incurred. It is difficult to reduce costs because it is processed in a drum factory. The drum is heavy.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems described in the prior art, and is easy to dispose after use, occupies a small space for storage, and has a light assembly type. It is intended to provide drums.

[0005]

The assembly type drum according to the present invention is provided with a shaft hole at a central portion, radially spaced from the center of the shaft hole, and a plurality of radially extending through holes at appropriate intervals. Two flanges made of a paper material such as a cardboard having a hole formed therein, and a cardboard provided with cutouts which can be inserted into the through holes and are provided on the inner long sides from both ends so as to be fitted to the flanges. And a plurality of strip-shaped body plates made of a paper material such as.

In another assembly type drum according to the present invention, a shaft hole is formed in a central portion, a plurality of through holes are radially spaced from a center of the shaft hole, and a plurality of through holes are radially formed at appropriate intervals. And two flanges made of a paper material such as a corrugated cardboard, and a shaft hole formed at the center, and a plurality of through holes radially spaced from the center of the shaft hole and radially spaced at appropriate intervals. And a middle flange made of a paper material such as a cardboard having a notch at the edge, and the flange and the middle flange which can be inserted through the through-hole and extend from both ends to the inner long side. And a plurality of strip-shaped body plates made of a paper material such as a cardboard provided with a notch that can be fitted into the body.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an example of the first embodiment of the present invention will be described with reference to the drawings.
As shown in the figure, the two flanges A, A are provided with a shaft hole 1 at the center thereof, radially separated from the center of the shaft hole 1, and provided with a plurality of radially spaced through holes 2 at appropriate intervals. Made of a paper material such as a cardboard with perforations.

As shown in FIG. 3, the strip-shaped body plate B can be inserted into the through hole 2 of the flange A, and the inner long sides a, b from both ends.
And a paper material such as a cardboard provided with a notch 3 which can be fitted to the flange A.

When assembling the flanges A, A and the body plate B,
As shown in FIG. 1, the body plate B is inserted into the through hole 2 of the flange A,
The notch 3 on the long side a of the body plate B is fitted to the side wall of the through hole 2 of the flange A on the shaft hole 1 side.

Next, the notch 3 on the long side b of the body plate B is shown in FIG.
4 is folded from the position shown by the dotted line as shown in FIG. 4 (bent to the right in FIG. 4).

[0011] The assembly operation is now completed. In this example, the notches 3 provided on the long sides a and b of the body plate 3 have the same length. However, the present invention is not limited to this. For example, the notch 3 on the long side b is replaced with the notch 3 on the long side a. It may be longer than 3.

An embodiment of the invention according to claim 2 will be described with reference to the drawings. In addition to the flanges A and A, a middle collar C is provided at a central portion as shown in FIG. A shaft hole 1 is drilled, a plurality of through holes 2 are radially spaced from the center of the shaft hole 1 and radially spaced at appropriate intervals, and a notch 4 provided with a notch 4 at an edge. It is made of paper materials such as

As shown in FIG. 7, the strip-shaped body plate B '
Dumbo which has a notch 5 which can be inserted into the through holes 2 of the flanges A, A and the middle flange C, and is provided on the inner long sides a ', b' from both ends and which can be fitted to the flanges A, A and the middle flange C. It is made of paper materials such as

When assembling the flanges A, A, the middle collar C and the body plate B ', as shown in FIG. 5, the body plate B' is inserted into the through holes 2 of the collars A, A and the middle collar C, The notch 5 on the long side a 'of the body plate B' is fitted to the side wall of the through holes 2 of the flanges A, A and the middle flange C on the shaft hole 1 side.

Next, the notch 5 on the long side b 'of the body plate B' is
From the position shown by the dotted line in FIG. 7, it is bent as shown in FIG. 8 (bent to the right in FIG. 8).
The left collar A and the middle collar C and the middle collar C and the right collar A are brought into contact with each other.

Thus, the assembling operation is completed. In this example, the notches 5 provided on the long sides a 'and b' of the body plate B 'have the same length. However, the present invention is not limited to this. The length may be longer than the notch 5 on the side a ′.

The drum assembled as shown in FIG. 5 has, for example, an optical cable wound two to three turns in a space formed by a left collar A and a middle collar C. Notch 4
Through which the remaining optical cable is wound around the space formed by the middle and right flanges C and A.

With this arrangement, when the cable is laid while being rewound from the drum, a new cable can be sequentially connected to the winding start end, so that the laying operation can be efficiently performed. There is an advantage that it can be implemented.

As can be seen from FIG. 1 and FIG.
B ′ is radially mounted on the collars A, A and the middle collar C,
Since the load of the wound cable is borne by the back of the body plates B and B ', the optical cable, IV, OW
It has sufficient strength for winding light electric wires and cables.

Also, at the time of assembling, a part of the body plates B and B '(dotted line portions in FIGS. 3 and 7) is bent and brought into contact between the flanges A and A or between the flange A and the middle collar C. , And serves as a reinforcing member for preventing the inward bending of the collars A, A and the middle collar C.

The number of through holes 2 is not limited, and can be freely increased or decreased as needed. There is no particular limitation on the paper material.

[0022]

As described above, the present invention has the following advantages. Disposal of the used drum is easy. It is not bulky and does not take up space for storage. Since it is not bulky, transportation costs can be saved. Since mass production can be performed at the paper processing plant, costs can be reduced. The drum is light.
