DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable storage case which is suitable for transportation and storage, and which allows easy feeding of a cable such as an electric wire or an optical fiber cable stored in a casing such as a cardboard.

[0002]

2. Description of the Related Art As a conventional cable storage case for storing a cable such as an electric wire or an optical fiber cable, there is one as shown in FIG.

That is, the cable storage case shown in FIG.
A cable bundle 1 in which a cable K is wound around substantially the same axis in a housing 100 formed of cardboard or the like.
02 is stored, and the cable K is stored in this state.
It is configured to be transported. When the cable K is pulled out from the housing 100, a cable outlet 101 is formed at the center of the upper surface of the housing 100, and the cable outlet 1 is formed.
It is configured to take out cable K from 01.

However, according to the cable storage case, the cable K taken out of the housing 100 is twisted or meandered. If the cable K is inadvertently straightened,
There is a possibility that the cable K may be damaged and electrical characteristics may be degraded.

Therefore, as shown in FIG.
Is formed into a cable winding bundle 102b. A twill winding means that the cable K is wound while applying a single twist every cycle of the winding, and when the cable K is pulled out from the cable winding 102b wound in such a way,
The twist generated at the time of the pull-out and the twist given in advance by the twill winding cancel each other out, and the cable K can be pulled out without causing the twist.

[0006]

However, FIG.
When the cable K is wrapped like a cable storage case shown in FIG. 5, the density of the cable K becomes coarse, the cable bundle 102b becomes large, and the transport efficiency and storage efficiency of the case storing the cable K decrease. There is a problem of doing.
In addition, a special device for performing such a twill winding is required.

As a device or case for pulling out the cable K without twisting or meandering, Japanese Utility Model Laid-Open No. 5-85757, Japanese Unexamined Patent Application Publication No. 8-225253, and Japanese Utility Model Application Laid-Open No. 63-1544.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cable storage case according to an embodiment of the present invention will be described below with reference to FIG.

This cable storage case is shown in FIGS.
As shown in FIG. 2, the cable bundle 20 is accommodated in the housing 10, and a pedestal 30 to which a support core member 40 is attached is interposed between the cable bundle 20 and the bottom surface of the housing 10.

The housing 10 is made of cardboard or the like, has a bottom surface formed in a substantially square shape, and has an outlet 12 for drawing out a cable on one side surface. The outlet 12 may be formed by cutting one side of the housing 10 with a cutter or the like, or may be perforated in advance on one side and opened after assembling the case.

The cable bundle 20 is formed by winding a cable K, such as an electric wire or an optical fiber cable, around substantially the same axis so as to form a hollow donut.

The pedestal 30 is made of a hard and rigid material, for example, a cardboard or the like.
The cable bundle 2 having a dimension slightly smaller than the side length and the cable bundle 2
0 is formed in a substantially disc shape slightly larger than the diameter of the bottom portion. A substantially cylindrical cable support shaft portion 34 having an outer diameter slightly smaller than the inner diameter of the cable bundle 20 is provided upright at the center thereof. The cable support shaft 34 is inserted through the hollow portion of the cable bundle 20 so that the cable bundle 20 is mounted on the pedestal 30.

The support core member 40 is made of a material such as a piece of wood, plastic, or the like that is hard and has a smooth surface and can reduce the coefficient of friction with the bottom of the housing. In addition, the shape is a diameter sufficiently smaller than the diameter of the pedestal 30, and when the pedestal 30 is stored in the housing 10, the pedestal 30 and the bottom surface of the housing 10 remain in contact such that the frictional resistance does not significantly increase. The semi-circular or go-stone-like shape or the go-stone is cut in half along the flat direction so that the support core member 40 is hard to bite into the bottom surface of the housing 10 while being finished to a height of about It is formed in a shape having a convex surface on both sides, a circular flat plate, or another rotating body shape.

Then, the support core member 40 is fixed to the center of the lower surface of the pedestal 30 and is housed in the housing 10, whereby the cable housing case is assembled.

When the cable K is pulled out of the cable storage case, as shown in FIG.
When the end portion of the cable K is taken out from the cable core and the end portion is pulled, the cable bundle 20 rotates together with the pedestal 30 with the support core member 40 as a fulcrum, and the cable K
Are sequentially fed out.

According to the cable storage case configured as described above, since the outlet 12 is provided on one side of the housing 10, when the cable K is pulled out from the outlet 12, the cable mounted on the pedestal 30. The cable K is sequentially fed out while the winding bundle 20 smoothly rotates around the support core member 40 together with the pedestal 30, and as a result, troubles such as twisting and meandering of the pulled-out cable K can be prevented.
Therefore, there is no need to extend the cable K as in the related art, and it is possible to prevent the electrical characteristics of the cable K from deteriorating even when the extracted cable K is laid. In addition, as a result that the cable K can be smoothly pulled out without twisting or the like, the workability of laying the cable K is excellent, and the appearance of the cable K after laying is good.

When the cable K is pulled out as described above,
Since the pedestal 30 rotates around the support core member 40 as a fulcrum with little contact with the bottom surface of the housing 10 or with a small frictional resistance, there is almost no frictional force that hinders the rotation,
The pedestal 30 and the cable bundle 20 rotate smoothly, and the cable K can be smoothly pulled out.

In order to prevent the cable K from being twisted,
Since it is not necessary to wire the cable K in the conventional way,
It is not necessary to use a special device for forming the cable bundle 20 in which the cable K is traversed, and the cable bundle 20 can be manufactured at low cost. In addition, the cable storage case can be downsized by using the cable bundle 20 in which the cable K is densely wound, and the case is excellent in transport efficiency and storage efficiency. More specifically, when the cable K having the same length is wound, a cable bundle 20 having a volume of about 80% is obtained as compared with the volume of the cable bundle 102b formed into a twill, shown in FIG.

In addition, the size can be reduced as described above, and
Since the cable K can be pulled out from the side surface of the housing 10, for example, when laying a plurality of cables K in parallel, a plurality of cable storage cases can be stacked up and down to perform the laying work, which is necessary for laying work. Work space is reduced.

It should be noted that only the cable bundle 20 is
In the case where the cable K is pulled out from the outlet 12 while being housed in the cable 0, the cable bundle 20 may not be able to rotate smoothly in the housing 10, and the cable K may bite into the cable bundle 20, or The cable bundle 20 may lose its shape. However, in this embodiment, since the pedestal 30 to which the support core member 40 is fixed is interposed between the cable bundle 20 and the bottom surface of the housing 10, the cable bundle 20 rotates smoothly around the support core member 40 as a fulcrum. However, such a situation can be more reliably prevented.

Further, since the cable support shaft portion 34 is inserted through the hollow portion of the cable bundle and the cable bundle 20 is mounted on the pedestal 30, the cable bundle 20 is supported by the support shaft portion 34. While rotating cable K
Is pulled out, so that the cable bundle 20 can be prevented from being deformed.

Since the cable storage case can be assembled only by mounting the cable bundle 20 on the pedestal 30 and storing the cable bundle 20 in the housing 10, the housing 10 is not subjected to any special processing or the like. The cable storage case can be assembled with a very simple operation.

When the housing 10 is formed of, for example, corrugated cardboard, the support core member 40 may bite into the bottom surface of the housing 10 and the smooth rotation of the pedestal 30 may be hindered.
In such a case, as shown in FIG. 3, if a hard sheet 50 made of plastic or the like is laid on the bottom surface of the housing 10, the support core member 40 hardly bites into the hard sheet 50, so that the pedestal 30 can rotate smoothly. it can.

The support core member 40 does not necessarily have to be fixed to the lower surface of the pedestal 30.
What is necessary is just to provide between the bottom surfaces and on the central axis of the cable bundle 20. For example, as shown in FIG. 4, even if a sheet 50b is interposed between the pedestal 30 and the bottom surface of the housing 10, and the support core member 40b is fixed to the upper surface of the sheet 50b, the same effect as in the above case is obtained. Can be obtained.

Further, the cable support shaft 34 erected at the center of the pedestal 30 does not need to have a columnar shape.
It may be formed in a polygonal column shape like the cable support shaft portion 34c shown in FIG. 5, or may be erected by crossing two vertical plates in a cross shape in plan view like the cable support shaft portion 34d shown in FIG. Good.

As shown in FIG. 7, an opening 12e formed on one side of the housing 10 is formed with a hole large enough to allow the cable K to pass therethrough, that is, slightly larger than the cross-sectional shape of the cable K. Hole.

FIG. 8 is a view showing the relationship between the storage form of the cable K and the pulling force of the cable K. Here, A is the case of the conventional example of FIG. 9, B is the case of the conventional example of FIG. 10, C is the case where the cable bundle 20 is stored in the housing 10 without using the pedestal 30, D is When the cable bundle 20 is stored in the housing 10 using the pedestal 30 to which the support core member 40 is not fixed, E indicates the case of the present embodiment shown in FIGS. 1 and 2, respectively.

According to this, when the cable bundle 20 is stored in the housing 10 as it is (C) or when the cable bundle 20 is stored in the housing 10 using the pedestal 30 to which the support core member 40 is not fixed. (D) shows the conventional case (A,
Although a larger pulling force is required than B), when the cable bundle 20 is housed as in the embodiment of the present invention in FIGS. 1 and 2 (E), it is the same as the conventional case (A, B). It can be seen that the drawing force is extremely small.

[0034]

As described above, according to the cable storage case of the present invention, the cable outlet formed on one side of the housing and the cable housed in the housing are wound around the vertical axis. A cable winding, a substantially disc-shaped pedestal interposed between the cable winding and the housing bottom, and a support core member provided on the vertical axis between the pedestal and the housing bottom. Since the pedestal on which the cable bundle is placed can be rotated around the support core member as the cable is pulled out from the cable outlet, the cable bundle smoothly rotates with the pedestal as the cable is pulled out. In addition, it is possible to prevent the occurrence of troubles such as twisting and meandering and to draw out the cable. Also, without twisting the cable, twisting of the cable drawn out can be prevented, so that a cable bundle tightly wound with the cable can be used. Excellent efficiency and storage efficiency.
Further, since the pedestal rotates extremely smoothly with the support core member as a fulcrum, the cable can be smoothly pulled out.

Moreover, the cable bundle is mounted on the base,
Since the cable storage case can be assembled by storing the cable storage case in the housing, the cable storage case can be assembled by a simple operation without performing any special processing on the housing.

When the support core member is provided at the center of the lower surface of the pedestal, if a hard sheet for preventing the support core member from digging into the bottom surface of the housing is interposed between the pedestal and the bottom surface of the housing, Since the support core member is prevented from digging into the bottom surface of the housing, it is possible to ensure a smooth extraction of the cable.

Further, when the cable support shaft is erected at the center of the pedestal and the cable support shaft is inserted through the center of the cable bundle, and the cable bundle is stored in the housing, the cable bundle is Is rotated while being supported by the support shaft portion, and it is possible to prevent the cable bundle from breaking down.
