DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a cable receiving basket according to the present invention will be described below in detail with reference to FIGS.

FIG. 1 is a side view showing a cable receiving cage, and FIG.
Is a side view showing a correction state of the cable entrance when the hanging start position of the flat cable is shifted from directly above the center of the cable catch, FIG. 3 is a plan view showing the vicinity of the cable entrance of the cable catch, FIG. 4 is a perspective view showing a cable receiver of the cable receiver cage. In addition, the same reference numerals are given to the same portions as those of the cable catch described in the related art, and the detailed description of the same reference numerals is omitted.

The cable receiving cage 1 is different from the conventional one in the following features. That is, as shown in FIG. 1, facing pieces 19, 19 having slots 19 a facing each other parallel to each other along the longitudinal direction of the upper side of the flat box-shaped thing in which the upper part of the cable receiving cage 1 is open. Provided,
On both sides of the flat cable F, there are provided rotating rollers 2 and 2 corresponding to a cable guide, each having a shaft 20 extending in the slots 19a and 19a.
a and a cable receiver 11 composed of a gantry 11b placed under the intermediate portion of the strip-shaped plate 11a.

The rotating rollers 2 and 2 provided with the shafts 20 extending transversely in the slots 19a and 19a are independently provided in the slots 19a.
a, 19a, that is, along the opening in the upper part of the cable receiving cage 1, it can be slid and fixed at an arbitrary position. In addition, the gantry portion 11b
It is a rectangular box that can be moved and fixed at an arbitrary position on the bottom of the cable receiving basket 1. In this embodiment, an intermediate connection terminal block 17 is provided inside, and also serves as a joint box. The belt-shaped plate 11a is placed on the gantry portion 11b, and both ends hang down, and the middle portion forms a raised ridge. In addition, the strip | belt-shaped board 11a may have flexibility uniformly uniformly,
As shown in FIG. 4, for example, V-shaped grooves may be provided at intervals in the width direction, and the V-shaped grooves may be provided with a turning property, that is, a concentrated bent portion that can be repeatedly bent.

The cable receiving basket 1 as described above can be handled as follows, and the loose flat cable F
Can be folded naturally left and right. In other words, when the wire rope W is wound up and the loose flat cable F is folded and stored in the cable receiving basket 1 while swinging naturally left and right, the flat cable F is moved to the left and right rotating rollers 2, 2. Rollers 2 and 2
Rotates easily. Therefore, the effective length La of the cable entrance 10a on the upper part of the cable receiving cage 1 (rotary rollers 2, 2)
The flat cable F can be naturally folded right and left as much as possible under its own weight and stored without having to make the distance between them so long.

In other words, although the loose flat cable F is naturally folded right and left and folded and stored in the cable receiving cage 1, it is necessary to restrict the effective length La of the cable entrance 10a to be narrow. Therefore, it is possible to make the right and left swing width of the flat cable F outside the cable receiving basket 1 within a narrow range, and it is possible to reduce the possibility of damage due to contact with an obstacle.

In addition, for the convenience of the stage, a cable fixture J (shown in FIG. 5) is provided just above the center of the cable receiving basket 1 so that the flat cable F cannot be suspended therefrom. For example, as shown in FIG. 2, even in a case where the flat cable F can only hang down from a position slightly biased to the right from directly above the center of the cable receiving basket 1, the rotating rollers 2 and 2 are respectively moved to the right. The gantry 11b is also moved to the right along with the
It can be adjusted so that the cable fixture J (shown in FIG. 5) is located directly above the center of the raised ridge of a.

Therefore, depending on the situation at the site, the cable receiving cage 1
Even if the flat cable F can only hang down from a position slightly deviated right or left from directly above the center of the cable, it is possible to prevent the flat cable F from being spilled due to uneven storage, Even if there is an obstacle between the fixture J (shown in FIG. 5) and the cable receiving cage 1, it can be avoided to some extent.

The cable guide for regulating the effective length of the cable inlet 10a is not limited to a rotary roller, but is coated with a Teflon-based resin having a small friction coefficient with a flat cable. It may be something like an aperture adjustment shutter.

[0027]

According to the first aspect of the present invention, since the cable guide is provided at the cable entrance, even if the cable entrance is restricted to be narrow, the flat cable is naturally folded right and left fully and stored. Can reduce the swing of the flat cable outside the cable catch when the loose flat cable naturally folds left and right, and the flat cable can be used as another obstacle. This provides an effect of providing an excellent cable receiving cage that can prevent damage due to contact with the cable.

According to the second aspect of the present invention, the effective length and the position of the cable entrance can be changed, so that in addition to the effect of the first aspect, the flat cable can be brought into contact with other obstacles. Position can be adjusted freely to prevent damage,
This has the effect of providing an excellent cable receiver that is easy to use.

According to the third aspect of the present invention, since the cable guide is a rotary roller, the frictional resistance between the cable guide and the flat cable can be made extremely small. Furthermore, the present invention has an effect of providing an excellent cable receiving cage which is simple and inexpensive, and can provide a flat cable that can be naturally folded fully left and right even when the cable entrance is narrowed.

According to the fourth aspect of the present invention, since the cable receiver includes the pedestal part movable to the left and right and the flexible band-shaped plate, the cable receiver is adjusted to the position of the cable inlet. The position of the raised portion of the flat cable can be moved, and in addition to the effect of the invention described in claim 3, even if the starting point of hanging of the flat cable is deviated to the left and right to some extent, the flat cable naturally moves to the left and right. It is possible to provide an excellent cable receiving cage that can be folded fully and can be stored without spillage of the flat cable.

According to the fifth aspect of the present invention, the gantry constituting the cable receiver is also used as a joint box. Therefore, in addition to the effect of the fourth aspect, an effective use of space can be achieved. This has the effect of providing a cable catch cage.
