When the cable 2 is pulled out, the inner retainer 3 rotates within the outer frame 4.

〔Example〕

Embodiments of the present invention will be explained in detail based on the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a cable pull-out device according to the present invention, and a cable 2 is wound in the form of a wire.
It is provided with a plurality of inner retainers 3 for holding the inner retainers 3, and an outer frame 4 in which the inner retainers 3 are rotatably and removably housed.

The inner retainer 3 is manufactured from a synthetic resin material or the like and has an upper and lower divided connection type, and in the illustrated example, it consists of upper and lower divided bodies 5 and 6 of the same shape, a bearing member 12 described later, and the like. The upper divided body 5 and the lower divided body 6 are
Horizontal flat disk portions 40, 40 each having a center hole 11, 11 therethrough, and peripheral wall portions 41, 41 vertically erected from the outer periphery of the flat disk portions 40, 40;
It has ring-shaped flat wall portions 42, 42 extending horizontally from the peripheral edges of the peripheral wall portions 41, 41 in a radially outward direction. As is clear from FIGS. 1 to 4, the outer frame 4 is a pipe frame having an upwardly opening shape and a circular shape in plan view, which is formed by bending pipe materials and connecting them by welding or the like. A rotary disk 9 is rotatably supported on a central shaft 8 formed on the inner bottom surface 7 in an upwardly projecting shape. Specifically, the hollow protrusion 10 at the center of the rotary disk 9 fits onto the central shaft 8 . The inner retainer 3 is further rotatably supported on the protruding portion 10 of the rotary disk 9, and specifically, a bearing member 12 that fits into the center hole 11 of both the divided bodies 5, 6.
The inner retainer 3 is attached to the protrusion 10 through the above-mentioned protrusion 10 , and the bearing member 12 is loosely or loosely fitted into the protrusion 10 of the rotary disk 9 .

That is, the cylindrical portion 43 of the bearing member 12 that connects and fixes the upper and lower divided bodies 5 and 6 is rotatably supported on a central shaft 8 erected on the outer frame 4 via a rotary disk 9.

Further, the upper and lower divided bodies 5 and 6 are integrally connected to the bearing member 12 and are connected and fixed to each other in an overlapping manner.
Specifically, the flat disc parts 40 and 40 of the upper and lower divided bodies 5 and 6 are overlapped, and the cylindrical part 43 of the flanged cylindrical bearing member 12 is inserted into each center hole of the upper and lower divided bodies 5 and 6. 11, 11, and screw the flanged nut member 13 onto the male screw formed in the cylindrical portion 43, and the flanged nut member 13 and the flange portion 12a of the bearing member 12 separate the upper and lower parts. The inner peripheral edges 5a, 6a of the bodies 5, 6 are pressed together and connected. As shown in the figure, the lower divided body 6 and the bearing member 12 are connected by bolts.
It is also possible to connect with a connecting tool 14 such as a nut, and 15 is a mounting hole for the connection. In this way, by connecting the upper and lower divided bodies 5 and 6,
A concave circumferential groove-shaped cable storage portion 16 that holds the cable 2 in a wound shape is formed by the circumferential wall portions 41, 41 and the flat wall portions 42, 42. This flat wall portion 42,4
2 has a lifting window portion 18... and a reinforcing protrusion 19...
...is attached. The outer circumferential side of the storage section 16 is open all the way around, and the stored cable 2 can be pulled out by arbitrarily rotating the inner retainer 3. Note that the width H of the opening 33 on the outer circumferential side is set large in the example shown so that it is suitable for thick and rigid wires such as VVF cables, but this width H can be freely increased or decreased. In the case of a thin cable, it is desirable to make this width dimension H sufficiently small.

Next, as shown in FIG. 6, as the outer frame 4,
It is also preferable to use a bottomed cylindrical container with an upward opening, for example, a press molded product of a metal plate or a plastic molded product. Cable outlet ports 21 are provided in the outer peripheral wall 20. In addition, if the gap G in Fig. 6 is set slightly smaller than the minimum diameter of the cable to be stored,
This is preferable since it has the advantage that it does not fall between the outer circumferential surface of the inner retainer 3 and the inner surface of the outer frame 4.

To pull out the cable 2 inside the inner retainer 3, the terminal section is taken out from the outlet 21 of the outer frame 4 and pulled, and the inner retainer 3 rotates together with the rotary disk 9 to continuously pull out the cable 2. can be extracted. To replace the inner retainer 3 with another inner retainer 3, as shown in FIG.
After that, the inner retainer 3 containing the desired cable 2 is fitted into the outer frame 4 from above. The above-mentioned attachment and detachment of the inner retainer 3 can be done by placing a hand on the lifting window 18, and therefore the radial distance between the outer frame 4 and the inner retainer 3, that is, the gap G, can be adjusted. There is no harm in setting it quite small. When the inner retainer 3 rotates, the weight of the inner retainer 3 including the cable 2 is supported by the central shaft 8 of the outer frame 4 along with the weight of the rotary disk 9. To separate the two divided bodies 5, 6, it is sufficient to simply remove the nut member 13.

In addition, if the outer frame 4 is constructed as shown in the embodiments shown in FIGS.
It can be composed of only 2... The central shaft 8 is joined to each end 24 of the hollow member 22 by welding or the like via a circular plate 23 disposed at the center.

Regarding other connection structures of the upper and lower divided bodies 5 and 6,
As shown in FIG. 9, a circumferential groove 25 is formed at or near the inner peripheral edge 5a of the upper divided body 5, and locking pieces 26 are slidably fitted into the circumferential groove 25.
is formed on the lower divided body 6, and the locking piece 26...
A projecting piece 27 that engages with the groove 25 is formed on the upper divided body 5 to project within the groove 25 at the same pitch and arc length. Both divided bodies 5 and 6 are interconnected by twisting one of them in the direction of the arrow.

Instead of the lifting windows 18 provided on the flat wall portions 42, 42 of the upper and lower divided bodies 5, 6, gripping protrusions 28 may be provided on the flat wall portions 42, 42 as shown in FIG. Preferably, it is also preferable to protrude in the inner radial direction as shown by the imaginary line.

The inner cage 3 according to each of the above embodiments has an outer frame 4
When not in use, that is, even when used alone, it can be used for pulling out the cable 2, and as shown in Fig. 8, the support rod 29 arranged horizontally supports both ends.
This can also be carried out by inserting it into the bearing member 12 of the inner retainer 3 and appropriately rotating it in the direction of the arrow.
Note that the upper and lower divided bodies 5 and 6 may be connected by providing screw portions (not shown) directly on each of the divided bodies 5 and 6 and then screwing them together.

The bearing member 12 serves to connect the upper and lower divided bodies 5 and 6, and by providing the bearing member 12, both the divided bodies 5 and 6 can be made into exactly the same shape, and therefore a common mold can be used. However, it is of course possible to omit the bearing member 12 by providing a threaded portion on either one of the two divided bodies 5, 6 and screwing it into the nut member 13.

Although the present invention is suitable for thick and heavy cables such as VVF cables, it can also be used with ordinary electric wires. Note that the term "cable" is used to include small-diameter insulated wires and the like. Although not shown, it may be preferable to use the inner retainer 3 as an integrated type that cannot be divided into upper and lower parts, and to selectively attach it to the outer frame 4 from a plurality of pieces. A bobbin can be used.

[Effect of idea]

The present invention has significant effects as described below.

The upper and lower divided bodies 5 and 6 of the inner retainer 3 can be quickly connected and fixed by simply screwing one nut member 13 onto the male thread of the bearing member 12, and the division can also be done using the nut member 13.
The cable 2 can be easily and quickly retained or replaced by simply removing it.

The cable storage section 16 of the inner holder 3 functions as a protective container that prevents the cable 2 held in a wound form from being bent or scratched by external force, and prevents the cable 2 from being bent or scratched due to external force. It is convenient because there is no need for packaging during storage, etc.

When the terminal side of the cable 2 is pulled, the inner retainer 3, which is pivotally supported on the central axis 8 of the outer frame 4, rotates easily and the cable 2 is pulled out smoothly and continuously, thereby preventing the cable 2 from becoming tangled. There is no.

This cable pulling device has a simple structure, can connect the upper and lower divided bodies 5 and 6, and can rotate the inner retainer 3, and can be manufactured at low cost with a small number of parts.
