[SUMMARY OF THE INVENTION]
[Problems to be solved by Invention]
[0005] In the above-described method, one of both end side parts of the optical fiber unit
is unwound from the upper side of the reel and is fed into one pipe, and the other
of both end side parts of the optical fiber unit is unwound from the lower side of
the reel and fed into the other pipe. In this way, since both end side parts of the
optical fiber unit are simultaneously unwound in the above-described method, it is
necessary to prepare two jetting machines, and it is necessary to synchronize the
feeding operation into the two pipes.

[MODE(S) FOR CARRYING OUT THE INVENTION]
[0010] Hereinafter, the embodiments of the present invention will be described with reference
to the drawings.
<<First Embodiment>>
[0011] FIG. 1 is a transparent perspective view showing a cable accommodating body in the
first embodiment of the present invention. In FIG. 1 and FIG. 2(a) to FIG. 2(d) described
later, a part of the container 20 or the entire container 20 is shown transparently
in order to facilitate understanding of the inside of the container 20.
[0012] As shown in FIG. 1, the cable accommodating body 1A of the present embodiment includes
a cable bundle 10 and a container 20 that accommodates the cable bundle 10. The cable
accommodating body 1A is used, for example, for the transporting work to the installation
site and the installing work itself at the time of the installing construction of
the cable 11.
[0013] The cable bundle 10 is formed by winding a single continuous cable 11 in an annular
shape (coil shape). In the present embodiment, the cable 11 constituting the cable
bundle 10 has no connection points between one end (first end) 12 and the other end
(second end) 13. The single continuous cable 11 may be configured by connecting a
plurality of cables, for example, by fusion bonding, connectors, or the like. That
is, as long as the cable is continuously connected without being divided between the
one end 12 and the other end 13, the "single continuous cable 11" in the present embodiment
may have no connection point between the ends 12 and 13 or may have one or more connection
points between the ends 12 and 13. Although an optical fiber cable can be exemplified
as a specific example of the cable 11, the cable 11 is not particularly limited thereto.
For example, a metal cable for power transmission, communication, or a combination
of these may be used as the cable 11.
[0014] As an example of the method of winding the cable 11 when forming the cable bundle
10, a traverse winding can be exemplified. The method of winding the cable 11 is not
particularly limited to the above, and the cable bundle 10 may be configured by winding
the cable 11 using other winding methods such as a figure-8 (eight) winding. For example,
the cable 11 may be wound to form the cable bundle 10 while applying the opposite
twist in the direction opposite to the twist at the time of unwinding of the cable
11 every time one winding of the cable 11 by the winding method as described in
JP Utility Model Registration No. 3035145 and
JP2000-255659A.
[0015] The cable bundle 10 of the present embodiment is formed, for example, by winding
the cable 11 using a parasol drum type winding device. In the winding device of this
type, the completed cable bundle 10 is removed from the winding device by contracting
the parasol drum after the winding of the cable 11. Therefore, the cable bundle 10
of the present embodiment has a so-called drumless structure in which the cable bundle
10 has no winding core such as a drum or a reel. As long as the cable bundle 10 does
not have a winding core, the cable bundle 10 may be formed using a winding device
of a type other than the parasol drum type described above.
[0016] In the present embodiment, since the cable bundle 10 has no winding core, the first
end 12 of the cable 11 and the second end 13 of the cable 11 can be simultaneously
unwound from the cable bundle 10. That is, it is possible to be simultaneously unwind
both ends 12 and 13 of the cable 11 from the cable bundle 10 in the present embodiment.
On the other hand, if the cable bundle is wound around the drum, the end on the winding
end side (E end, for example, one end) can be unwound from the cable bundle, but the
end on the winding start side (S end, for example, the other end) cannot be unwound
from the cable bundle because the end on the winding start side is fixed to the drum.
[0017] Further, in the present embodiment, since the cable bundle 10 has no winding core,
it is not necessary to rotate the cable bundle 10 itself when unwinding the cable
11, and it is possible to independently unwind both ends 12 and 13 of the cable 11
from the cable bundle 10. On the other hand, in the method described in Patent Document
1 described above, since it is necessary to simultaneously unwind both ends of the
cable with the rotation of the reel, it is impossible to independently unwind both
ends of the cable.
[0018] The container 20 is, for example, a box having six planes 21a to 21f and accommodates
the cable bundle 10 described above therein. The shape of the container 20 is not
particularly limited to the above as long as the container 20 has a space that can
accommodates the cable bundle 10. For example, the container 20 may have cylindrical
shape. By accommodating the cable bundle 10 in such a container 20, it is possible
to easily transport the cable bundle 10 and to suppress the occurrence of collapse
of the cable bundle 10.
[0019] In the present embodiment, the cable bundle 10 is accommodated in the container 20
in a horizontal posture, and the cable bundle 10 is disposed in the container 20 with
a posture (i.e., " horizontal posture") in which the winding axial L
1 of the cable bundle 10 is substantially parallel to the horizontal direction (XY
plane direction in the drawing). In this way, by accommodating the cable bundle 10
in the container 20 in the horizontal posture, it is possible to suppress the occurrence
of kinking in the cable 11 due to the weight of the cable bundle 10 or the like. In
the second to fifth embodiments described later, the cable bundle 10 may be accommodated
in the container in the horizontal posture.
[0020] Although not particularly limited, for example, the container 20 is formed using
cardboard made of paper. For example, the container 20 may be formed using a plastic
cardboard made of a resin material such as polypropylene (PP), or the container 20
may be formed using a metallic box.
[0021] As shown in FIG. 1, the container 20 of the present embodiment has two outlets 22
and 23. The first outlet 22 is formed in a first plane 21a that is the left side plane
of the box in FIG. 1. The first outlet 22 penetrates the first plane 21a in the thickness
direction of the first plane 21a. On the other hand, the second outlet 23 is formed
in the second plane 21b that is the right side plane of the box in FIG. 1. The second
outlet 23 also penetrates the second plane 21b in the thickness direction of the second
plane 21b.
[0022] Both of the first and second planes 21a and 21b are substantially perpendicular to
the winding axial direction L
1 of the cable bundle 10, and the first and second outlets 22 and 23 are respectively
formed in the first and second planes 21a and 21b that are opposite to each other.
The cable 11 is pulled out from the container 20 through the first outlet 22, and
the first end 12 side of the cable 11 passes through the first outlet 22. On the other
hand, the cable 11 is also pulled out from the container 20 through the second outlet
23, and the second end 13 side of the cable 11 passes through the second outlet 23.
[0023] The posture of the cable bundle 10 in the container 20 and the planes in which the
first and second outlets 22 and 23 are formed are not particularly limited to the
above. FIG. 2(a) to FIG. 2(d) are transparent perspective views showing the first
to fourth modifications of the cable accommodating body in the first embodiment of
the present invention.
[0024] For example, as shown in FIG. 2(a), the cable accommodating body 1A shown in FIG.
1 may be used with being rotated 90 degrees clockwise. In this case, since the first
plane 21a is the lid plane of the box in the drawing and the second plane 21b is the
bottom plane of the box in the drawing, the first outlet 22 is located above the cable
bundle 10 and the second outlet 23 is located below the cable bundle 10. Further,
the cable bundle 10 is accommodated in the container 20 in a vertical posture, the
cable bundle 10 is disposed in the container 20 with a posture (i.e., "vertical posture")
in which the winding axial direction L
1 of the cable bundle 10 is substantially parallel to the vertical direction (Z direction
in the drawing).
[0025] Alternatively, as shown in FIG. 2(b), the first and second outlets 22 and 23 may
be formed in the third and fourth planes 21c and 21d. Alternatively, as shown in FIG.
2(c), the first outlet 22 may be formed in the first plane 21a, and the second outlet
23 may be formed in the fourth plane 21d. Alternatively, as shown in FIG. 2(d), both
the first and second outlets 22 and 23 may be formed in the same plane 21a. In FIG.
2(a) to FIG. 2(d), the third and fourth planes 21c and 21d are the side planes of
the box in the drawing. Although the third plane 21c and the fourth plane 21d are
opposite to each other in FIG. 2(b), it is not particularly limited thereto. For example,
the third plane 21c and the fourth plane 21d may be planes adjacent to each other.
[0026] In the second and fifth embodiments, the first and second outlets 22 and 23 may be
formed in the planes shown in FIG. 2(a) to FIG. 2(c). Alternatively, in the third
and fourth embodiments, the first and second outlets 22 and 23 may be formed in the
planes shown in FIG. 2(b) to FIG. 2(d).
[0027] Returning to FIG. 1, the container 20 of the present embodiment may have protrusions
24 on the inner wall of the container 20. Each of the protrusions 24 has a triangular
cross-sectional shape and extends in a direction (Y direction in the drawing) substantially
perpendicular to the winding axis L
1 of the cable bundle 10. Each of the protrusions 24 is formed of, for example, a cardboard
having an L-shaped cross-sectional shape and is formed by being attached to the inner
surface of the container 20. The cross-sectional shape of the protrusion 24 is not
particularly limited to the above as long as it protrudes in a convex shape and may
be, for example, a rectangular shape or an arc shape. The protrusion 24 may be formed
of a plastic cardboard or a metal member instead of a cardboard made of paper.
[0028] The protrusions 24 is disposed on the third and fourth planes 21c and 21d connecting
the first plane 21a and the second plane 21b described above. The protrusions 24 are
disposed on the inner surface of the third plane 21c and are disposed on the inner
surface of the fourth plane 21d. The third plane 21c is the bottom plane of the box
in FIG. 1, while the fourth plane 21d is the lid plane of the box in FIG. 1. The protrusions
24 are arranged in parallel to each other on the upper surface (inner surface) of
the third plane 21c to form a wave-shaped structure. Similarly, the protrusions 24
are arranged in parallel to each other on the lower surface (inner surface) of the
fourth plane 21d to form a wave-shaped structure. The number of protrusions 24 disposed
on one plane is not particularly limited and may be arbitrarily set.
[0029] By forming such a wave-shaped structure consisting of the protrusions 24 on the planes
21c and 21d substantially parallel to the axial direction L
1 of the cable bundle 10, it is possible to insert the protrusions 24 between the cable
11 constituting the cable bundle 10 and to hold the cable 11 by the protrusions 24.
Thus, even when the cable bundle 10 is accommodated in the container 20 in a horizontal
posture, it is possible to suppress the cable bundle 10 from falling down or collapsing.
[0030] The plane on which the wave-shaped structure consisting of the protrusions 24 is
formed is not particularly limited to the above as long as the plane is substantially
parallel to the axial L
1 of the cable bundle 10. For example, the protrusions 24 may be disposed on the fifth
and sixth planes 21e and 21f. The fifth plane 21e is the front plane of the box in
FIG. 1, and the sixth plane 21f is the back plane of the box in FIG. 1. Alternatively,
the protrusions 24 may be disposed on the third to sixth planes 21c to 21f (that is,
all the planes of the box substantially parallel to the axial direction L
1 of the cable bundle 10). In the second to fifth embodiments, for example, when the
cable bundle is accommodated in the container in the horizontal posture, the container
may have the convex protrusions 24.
[0031] FIG. 3 is a cross-sectional view showing the fifth modification of the cable accommodating
body viewed from the side in the first embodiment of the present invention.
[0032] Instead of the protrusions 24 described above, as shown in FIG. 3, the inclined surfaces
25a and 25b may be disposed on the planes 21c to 21f substantially parallel to the
axial direction L
1 of the cable bundle 10. The first inclined surface 25a is inclined with respect to
the direction axial L
1 of the cable bundle 10 and has a tapered funnel shape in which the accommodating
space narrows as approaching the first outlet 22. The second inclined surface 25b
is also inclined with respect to the axial direction L
1 of the cable bundle 10 and has a tapered funnel shape in which the accommodating
space narrows as approaching the second outlet 23.
[0033] By holding the entire cable bundle 10 by the inclined surfaces 25a and 25b, even
when the cable bundle 10 is accommodated in the container 20 in a horizontal posture,
it is possible to suppress the cable bundle 10 from falling down or collapsing. In
the case of the example shown in FIG. 3, the shape of the cable bundle 10 can be matched
to the inclined surfaces 25a and 25b, for example, by varying the number of windings
of the cable 11 in the axial direction L
1 of the cable bundle 10. In the second to fifth embodiments, for example, when the
cable bundle is accommodated in the container in the horizontal position, the container
may have inclined surfaces 25a and 25b.
[0034] For example, when there is no possibility of the cable bundle 10 falling down or
collapsing, or when the cable bundle 10 is disposed in the container 20 in the vertical
posture as shown in FIG. 2 (a) to FIG. 2 (d), the container 20 may not have the protrusions
24 or the inclined surfaces 25a and 25b.
[0035] Below, the method of installing the cable 11 by the air blown cable installing method
using the cable accommodating body 1A described above will be explained with reference
to FIG. 4 (a) to FIG. 4 (d). FIG. 4(a) to FIG. 4(d) are diagrams showing a cable installing
method in the first embodiment of the present invention.
[0036] First, as shown in FIG. 4(a), two ducts 51 and 52 are laid. The ducts 51 and 52 may
be ducts already laid. Next, the above-described cable accommodating body 1A is placed
between the two ducts 51 and 52, and the jetting machine 60 is set at one end of the
first duct 51. Next, the operator (see FIG. 1) pulls out the first end 12 of the cable
11 through the first outlet 22 of the container 20 and inserts it into the jetting
machine 60.
[0037] Next, as shown in FIG. 4(b), the air subjected to the drying process is supplied
from the compressor 70 to the jetting machine 60. The jetting machine feeds the cable
11 into the first duct 51, for example, by the air and pushing with a caterpillar,
and the first end 12 side of the cable 11 is sequentially fed out from the container
20 through the first outlet 22 along with this feeding. Then, when the first end 12
of the cable 11 is exposed from the opposite end of the first duct 51, the jetting
machine 60 is stopped. As a result, the installing work of the cable 11 into the first
duct 51 is completed.
[0038] Next, as shown in FIG. 4(c), the jetting machine 60 is removed from the end of the
first duct 51 and is set at one end of the second duct 52. Then, the operator (see
FIG. 1) pulls out the second end 13 of the cable 11 through the second outlet 23 of
the container 20 and inserts the cable 11 into the jetting machine 60.
[0039] Next, as shown in FIG. 4(d), the air subjected to the drying process is supplied
from the compressor 70 to the jetting machine. The cable 11 is fed into the second
duct 52 by the air and pushing with the jetting machine 60 to sequentially feed out
the second end 13 side of the cable 11 from the container 20 through the second outlet
23. Then, when the second end 13 of the cable 11 is exposed from the opposite end
of the second duct 52, the jetting machine 60 is stopped. As a result, the installing
work of the cable 11 into the second duct 52 is completed.
[0040] Next, after removing the container 20 of the cable accommodating body 1A from the
cable 11, the installing work the cable 11 into the ducts 51 and 52 is completed by
connecting the ends of the two ducts 51 and 52.
[0041] Although the installation of cable 11 into the other duct 52 is started after the
installation of cable 11 into one duct 51 is completed in the above-described cable
installing method, the timing of installation of two ducts 51 and 52 is not particularly
limited to this. For example, when two jetting machines 60 can be prepared, the installing
work of the cable 11 into one duct 51 and the installing work of the cable 11 to the
other duct 52 may be carried out in parallel. In this case, since it is possible to
individually and independently perform the installing work of the cable 11 into the
two ducts 51 and 52 without synchronizing by using the cable accommodating body 1A
of the present embodiment, it is excellent workability.
[0042] In the present embodiment, since the cable bundle 10 has no winding core and the
container 20 accommodating the cable bundle 10 has the first and second outlets 22
and 23 through which the cable 11 is pulled out from the inside of the container 20,
it is possible to independently unwind both ends 12 and 13 of the cable 11 from the
cable bundle 10.
<<Second Embodiment>>
[0043] FIG. 5(a) is a cross-sectional view showing a cable accommodating body viewed from
the side in the second embodiment of the present invention, and FIG. 5(b) is a cross-sectional
view taken along VB-VB of FIG. 5(a). FIG. 6(a) to FIG. 6(c) are diagrams showing a
winding method of a cable bundle in the second embodiment of the present invention.
[0044] The present embodiment is different from the modification shown in FIG. 2(d) of the
first embodiment described above mainly in that (a) the cable bundle is divided into
a plurality of cable bundles 10A and 10B and (b) the container 20 has a partition
plate 26. Hereinafter, the cable accommodating body 1B in the second embodiment will
be described only with respect to differences from the first embodiment, parts having
the same configuration as those in the first embodiment are denoted by the same reference
numerals, and description thereof will be omitted.
[0045] As shown in FIG. 5(a), the cable accommodating body 1B of the present embodiment
includes a plurality of (two in the present embodiment) cable bundles 10A and 10B.
The cable bundles 10A and 10B are continuously connected together by a single cable
11. That is, the cables 11 constituting the cable bundles 10A and 10B has no connection
points between the first end 12 and the second end 13. The single continuous cable
11 may be configured by connecting a plurality of cables, for example, by fusion bonding,
connectors, or the like, and this cable 11 may be used to form a plurality of cable
bundles 10A and 10B. In this case, the connection point is preferable located in the
cable bundles 10A and 10B. Thus, even if stresses are applied to the part of the cable
11 between the cable bundles 10A and 10B (the part of the cable 11 that connects the
cable bundles 10A and 10B), it is possible to suppress the occurrence of a defect
at the connection point. The number of the cable bundles included in the cable accommodating
body 1B is not particularly limited to the above as long as it is plural.
[0046] The cable bundle 10A and 10B is formed as follows.
[0047] That is, first, as shown in FIG. 6(a), the cable bundle 10B is formed by winding
the cable 11 supplied from the supplying drum 80 using the above-described parasol
drum type winding device. At this time, the second end 13 of the cable 11 is located
below the cable bundle 10B.
[0048] Next, after removing the cable bundle 10B from the winding device, the cable bundle
10B is reversed as shown in FIG. 6(b). As a result, the second end 13 of the cable
11 is located above the cable bundle 10B.
[0049] Next, as shown in FIG. 6(c), the cable bundle 10A is formed by winding the cable
11 supplied from the supplying drum 80 using the above-described parasol drum type
winding device. At this time, the first end 12 of the cable 11 is located above the
cable bundle 10B. Since the cable bundle 10A is formed without cutting the cables
11 after forming the cable bundle 10B, the two cable bundles 10A and 10B are continuously
connected by the single cable 11.
[0050] The method of forming the cable bundles 10A and 10B is not particularly limited to
the above method. For example, the cable-bundles 10A and 10B may be formed by the
following method. That is, after forming the cable bundle 10B in the manner shown
in FIG. 6(a), the cable bundle 10A is formed without removing the cable bundle 10B
from the winding device. Then, after removing the two cable bundles 10A and 10B from
the winding device, the cable bundle 10B may be reversed.
[0051] Returning to FIG. 5(a), the container 20 of the present embodiment has a partition
plate 26, and the partition plate 26 divides the inner space of the container 20 into
two accommodating rooms 27a and 27b. The two cable bundles 10A and 10B described above
are individually accommodated in these two accommodating rooms 27a and 27b. Specifically,
the cable bundle 10A is accommodated in the accommodating room 27a, and the cable
bundle 10B is accommodated in the accommodating room 27b. At this time, both cable
bundles 10A and 10B are accommodated in the accommodating rooms 27a and 27b in a vertical
posture. The container 20 may have a plurality of partition plates 26 according to
the number of the cable bundles included in the cable accommodating body 1B.
[0052] In the first, third, and fourth embodiments, the container may include a partition
plate that partitions the inner space of the container into a plurality of accommodating
rooms, and the cable accommodating body may have a plurality of cable bundles individually
accommodated in the plurality of accommodating rooms.
[0053] The partition plate 26 has two through holes 28 and 29. Both of the two through holes
28 and 29 penetrate the partition plate 26 in the thickness direction thereof. The
first end 12 of the cable 11 is pulled out from the inside of the container 20 through
the first outlet 22 formed in the first plane 21a of the container 20. The part of
the cable 11 between the cable bundles 10A and 10B passes through the first through
hole 28 of the partition plate 26. The second through hole 29 is formed in the partition
plate 26 so as to face the second outlet 23 formed in the first plane 21a of the container
20. The second end 13 of the cable 11 enters the upper accommodating room 27a from
the lower accommodating room 27b through the second through hole 29 and is further
pulled out from the inside of the container 20 through the second outlet 23.
[0054] In the present embodiment, since the cable bundles 10A and 10B have no winding core
and the container 20 accommodating the cable bundles 10A and 10B has the first and
second outlets 22 and 23 through which the cable 11 is pulled out from the inside
of the container 20, it is possible to independently unwind both ends 12 and 13 of
the cable 11 from the cable bundles 10A and 10B.
[0055] Further, in the present embodiment, the partition plate 26 partitions the inside
of the container 20 into a plurality of accommodating rooms 27a and 27b, and the plurality
of cable bundles 10A and 10B are individually accommodated in the plurality of accommodating
rooms 27a and 27b. Therefore, even when the cable bundles 10A and 10B are disposed
in the container 20 in the vertical posture, since the cable 11 can be pulled out
upward for both cable bundles 10A and 10B, it is possible to suppress the occurrence
of kinking in the cable 11 due to the weight of the cable bundles 10A and 10B or the
like. If there is no effect on the cable 11 such as the occurrence of kinking, the
outlet 23 may be arranged on the accommodating room 27b side, and the through hole
29 may be omitted.
<<Third Embodiment>>
[0056] FIG. 7(a) is a cross-sectional view showing a cable accommodating body viewed from
the side in the third embodiment of the present invention, and FIG. 7(b) is a diagram
showing a state in which the inner containers shown in FIG. 7(a) are taken out from
the outer container.
[0057] The present embodiment is different from the second embodiment described above mainly
in that (a) the plurality of cable bundles 10A and 10B are accommodated in separate
containers 20A and 20B and (b) the plurality of containers 20A and 20B are further
accommodated in an outer container 30. Hereinafter, the cable accommodating body 1C
in the third embodiment will be described only with respect to differences from the
second embodiment, parts having the same configuration as those in the second embodiment
are denoted by the same reference numerals, and description thereof will be omitted.
[0058] As shown in FIG. 7(a), the cable accommodating body 1C of the present embodiment
includes a plurality of (two in the present embodiment) containers 20A and 20B. The
two containers 20A are stacked in the vertical direction. The cable bundles 10A and
10B are individually accommodated in the two containers 20A and 20B. Specifically,
one cable bundle 10A is accommodated in the upper container 20A, and the other cable
bundle 10B is accommodated in the lower container 20B. At this time, both cable bundles
10A and 10B are accommodated in the containers 20A and 20B in the vertical posture.
The number of containers included in the cable accommodating body 1C is not particularly
limited to the above, and for example, the number of containers can be set according
to the number of cable bundles included in the cable accommodating body 1C.
[0059] The first end 12 of the cable 11 is pulled out from the inside of the upper container
20A through the first outlet 22 of the upper container 20A. The part of the cable
11 between the cable bundles 10A and 10B passes through the second outlet 23 of the
upper container 20A and the first outlet 22 of the lower container 20B. Further, the
second end 13 of the cable 11 is pulled out from the inside of the lower container
20B through the second outlet 23 of the lower container 20B.
[0060] In the present embodiment, in the upper container 20A, the first outlet 22 is formed
in the first plane 21a, and the second outlet 23 is formed in the second plane 21b.
On the other hand, in the lower container 20B, the first outlet 22 is formed in the
second plane 21b, and the second outlet 23 is formed in the first plane 21a. The second
outlet 23 of the upper container 20A may be formed in the side plane of the upper
container 20A. The first outlet 22 of the lower container 20B may be formed in the
side plane of the lower container 20B.
[0061] Further, the cable accommodating body 1C of the present embodiment includes an outer
container 30. The two containers 20A and 20B are accommodated in the outer container
30 in a state where the containers 20A and 20B are stacked on each other. At this
time, the upper container 20A and the lower container 20B are stacked to be out of
alignment, and the second outlet 23 of the lower container 20B is exposed from the
upper container 20A. The container 20B may be stacked on the container 20A. In this
case, the containers 20A and 20B are stacked to be out of alignment so that the first
outlet 22 of the container 20A is exposed from the container 20B.
[0062] Third and fourth outlets 32 and 33 are formed in the upper plane 31a of the outer
container 30. The third outlet 32 faces the first outlet 22 of the upper container
20A. The first end 12 of the cable 11 is pulled out from the inside of the upper container
20A to the outside of the outer container 30 through the first outlet 22 of the upper
container 20A and the third outlet 32 of the outer container 30. Similarly, the fourth
outlet 33 faces the second outlet 23 of the lower container 20B. The second end 13
of the cable 11 is pulled out from the inside of the lower container 20B to the outside
of the outer container 30 through the second outlet 23 of the lower container 20B
and the fourth outlet 33 of the outer container 30. The plane of the outer container
30 in which the third and fourth outlets 32 and 33 are formed is not limited to the
upper plane 31a, and the third and fourth outlets 32 and 33 may be formed in the side
plane or the bottom plane of the outer container 30. The third and fourth outlets
32 and 33 may be formed in different planes of the outer container 30.
[0063] In the first, second, and fifth embodiments, the cable accommodating body may include
a plurality of containers. In this case, a plurality of containers may be stacked
on each other such that the winding axial direction of the cable bundle is in the
vertical direction. In the first, second, and fifth embodiments, the cable accommodating
body may include an outer container that accommodates the plurality of containers.
[0064] When the cable 11 is installed using the cable accommodating body 1C of the present
embodiment, the first end 12 side of the cable 11 is fed out from the first outlet
22 of the upper container 20A into the first duct 51. On the other hand, the second
end 13 side of the cable 11 is fed out from the second outlet 23 of the lower container
20B into the second duct 52.
[0065] As shown in FIG. 7(b), the cable accommodating body 1C may be placed at the installation
site in a state in which the inner containers 20A and 20B are taken out from the outer
container 30. Therefore, it is possible to facilitate the short distance transporting
of the cable accommodating body 1C at the installation site. Further, even when the
space for placing the cable accommodating body at the installation site is small,
it is possible to cope with the site by taking out the inner containers 20A and 20B
from the outer container 30 and dividing the cable accommodating body 1C into the
containers 20A and 20B.
[0066] In the present embodiment, since the cable bundles 10A and 10B have no winding core
and the containers 20A and 20B accommodating the cable bundles 10A and 10B respectively
have the first and second outlets 22 and 23 through which the cable 11 is pulled out
from the inside of the containers 20A and 20B, it is possible to independently unwind
both ends 12 and 13 of the cable 11 from the cable bundles 10A and 10B.
[0067] Further, in the present embodiment, the plurality of cable bundles 10A and 10B are
individually accommodated in the plurality of containers 20A and 20B. Therefore, even
when the cable bundles 10A and 10B are disposed in the containers 20A and 20B in the
vertical posture, since the cable 11 can be pulled out upward for both cable bundles
10A and 10B, it is possible to suppress the occurrence of kinking in the cable 11
due to the weight of the cable bundles 10A and 10B or the like.
[0068] Further, in the present embodiment, since the two containers 20A and 20B are accommodated
in one outer container 30, it is possible to efficiently transport the cable accommodation
body 1C.
<<Fourth Embodiment>>
[0069] FIG. 8 is a cross-sectional view showing a cable accommodating body viewed from the
side in the fourth embodiment of the present invention.
[0070] The present embodiment is different from the third embodiment described above mainly
in that the cable accommodating body 1D includes four cable bundles 10A to 10D and
four containers 20A to 20D. Hereinafter, the cable accommodating body 1D in the fourth
embodiment will be described only with respect to differences from the third embodiment,
parts having the same configuration as those in the third embodiment are denoted by
the same reference numerals, and description thereof will be omitted.
[0071] As shown in FIG. 8, the cable accommodating body 1D of the present embodiment includes
two cable bundles 10C and 10D in addition to the two cable bundles 10A and 10B. That
is, the cable accommodating body 1D includes four cable bundles 10A to 10D. The cable
bundles 10A to 10D are continuously connected together by a single cable 11, and the
cables 11 constituting the cable bundles 10A to 10D has no connection points between
the first end 12 and the second end 13. The single continuous cable 11 may be configured
by connecting a plurality of cables, for example, by fusion bonding, connectors, or
the like, and this cable 11 may be used to form a plurality of cable bundles 10A to
10D. In this case, the connection point is preferable located in the cable bundles
10A to 10D.
[0072] Further, the cable accommodating body 1D includes two containers 20C and 20D in addition
to the two containers 20A and 20B in order to individually accommodate the cable bundles
10A to 10D. That is, the cable accommodating body 1D includes four containers 20A
to 20D. Specifically, the cable bundle 10A is accommodated in the container 20A, the
cable bundle 10B is accommodated in the container 20B, the cable bundle 10C is accommodated
in the container 20C, and the cable bundle 10D is accommodated in the container 20D.
At this time, all cable bundles 10A to 10D are accommodated in containers 20A to 20D
in the vertical posture.
[0073] In the present embodiment, the four containers 20A to 20D are stacked in the vertical
direction. Specifically, the containers 20C and 20D are stacked between containers
20A and 20B. The four containers 20A to 20D are accommodated in the outer container
30 in a state where the containers 20A to 20D are stacked on each other. At this time,
the container 20D and the container 20B are stacked to be out of alignment, and the
second outlet 23 of the container 20B is exposed from the container 20D.
[0074] The first end 12 of the cable 11 is pulled out from the inside of the container 20A
to the outside of the outer container 30 through the first outlet 22 of the container
20A and the third outlet 32 of the outer container 30. On the other hand, the second
end 13 of the cable 11 is pulled out from the inside of the container 20B to the outside
of the outer container 30 through the second outlet 23 of the container 20B and the
fourth outlet 33 of the outer container 30.
[0075] The part of the cable 11 between the cable bundles 10A and 10C passes through the
second outlet 23 of the container 20A and the first outlet 22 of the container 20C.
Similarly, the part of the cable 11 between the cable bundles 10C and 10D passes through
the second outlet 23 of the container 20C and the first outlet 22 of the container
20D. Further, the part of the cable 11 between the cable bundles 10D and 10B also
passes through the second outlet 23 of the container 20D and the first outlet 22 of
the container 20B.
[0076] When the cable 11 is installed using the cable accommodating body 1D of the present
embodiment, the first end 12 side of the cable 11 is sequentially fed out from the
first outlets 22 of the containers 20A, 20C and 20D into the first duct 51. On the
other hand, the second end 13 side of the cable 11 is fed out from the second outlet
23 of the container 20B into the second duct 52.
[0077] That is, in the present embodiment, since the first duct 51 is longer than the second
duct 52, the cable 11 of the three upper cable bundles 10A, 10C and 10D in the outer
container 30 is installed in the first duct 51, and the cable 11 of only the lowest
one cable bundle 10B is installed in the second duct 52. In this way, in the present
embodiment, it is possible to set the number of the cable bundles in which the cable
11 installed in the first duct 51 is wound and the number of the cable bundles in
which the cable 11 installed in the second duct 52 is wound according to the length
of each of the ducts 51 and 52.
[0078] Although not particularly shown, at the installation site, the cable accommodating
body 1D may be placed in a state where the inner containers 20A to 20D are taken out
from the outer container 30. Therefore, it is possible to facilitate the short distance
transporting of the cable accommodating body 1D at the installation site, and it is
also possible to cope with the installation site having a small space.
[0079] In the present embodiment, since the cable bundles 10A to 10D have no winding core
and the containers 20A to 20D accommodating the cable bundles 10A to 10D respectively
have the first and second outlets 22 and 23 through which the cable 11 is pulled out
from the inside of the containers 20A to 20D, it is possible to independently unwind
both ends 12 and 13 of the cable 11 from the cable bundles 10A to 10D.
[0080] Further, in the present embodiment, the plurality of cable bundles 10A to 10D are
individually accommodated in the plurality of containers 20A to 20D. Therefore, even
when the cable bundles 10A to 10D are disposed in the containers 20A to 20D in the
vertical posture, since the cable 11 can be pulled out upward for all the cable bundles
10A to 10D, it is possible to suppress the occurrence of kinking in the cable 11 due
to the weight of the cable bundles 10A to 10D or the like.
[0081] Further, in the present embodiment, since the four containers 20A to 20D are accommodated
in one outer container 30, it is possible to efficiently transport the cable accommodation
body 1D.
«Fifth Embodiment»
[0082] FIG. 9 is a transparent perspective view showing a cable accommodating body in the
fifth embodiment of the present invention. Similar to FIG. 2(a) to FIG. 2(d) described
above, the entire container 20 is shown transparently in FIG. 9 in order to facilitate
understanding of the inside of the container 20.
[0083] The present embodiment is different from the second embodiment described above mainly
in that (a) the container 20 does not have the partition plate 26 and (b) the other
cable bundle 10B is disposed inside one cable bundle 10A. Hereinafter, the cable accommodating
body 1E in the fifth embodiment will be described only with respect to differences
from the second embodiment, parts having the same configuration as those in the second
embodiment are denoted by the same reference numerals, and description thereof will
be omitted.
[0084] In the present embodiment, since the container 20 of the cable accommodating body
1E does not have a partition plate 26, one cable bundle 10A has the first inner diameter
D
1, whereas the other cable bundle 10B has the first outer diameter D
2 smaller than the first inner diameter D
1 (D
2<D
1). The cable bundle 10B is disposed inside the cable bundle 10A. At this time, both
cable bundles 10A and 10B are accommodated in the container 20 in the vertical posture.
In the first to fourth embodiments, the cable accommodating body may include first
and second cable bundles, and the second cable bundle may be disposed inside the first
cable bundle.
[0085] The number of the cable bundles included in the cable accommodating body 1E is not
particularly limited to the above as long as it is plural. Also in this case, it is
possible to accommodate the plurality of cable bundles in a nested manner by making
the diameters of the plurality of cable bundles different from each other.
[0086] The first end 12 of the cable 11 is pulled out from the inside of the container 20
through the first outlet 22 formed in the upper plane 21a of the container 20. The
second end 13 of the cable 11 is also pulled out from the inside of the container
20 through the second outlet 23 formed in the upper plane 21a of the container 20.
[0087] In the present embodiment, since the cable bundles 10A and 10B have no winding core
and the container 20 accommodating the cable bundles 10A and 10B has the first and
second outlets 22 and 23 through which the cable 11 is pulled out from the inside
of the container 20, it is possible to independently unwind both ends 12 and 13 of
the cable 11 from the cable bundles 10A and 10B. In the present embodiment, after
the unwinding work of the first end 12 side of the cable 11 is completed, the unwinding
work of the second end 13 side of the cable 11 is started.
[0088] It should be noted that the embodiment described above are described to facilitate
understanding of the present disclosure and are not described to limit the present
disclosure. It is therefore intended that the elements disclosed in the above embodiment
include all design modifications and equivalents to fall within the technical scope
of the present disclosure.
