2. Description of the Related Art Conventionally, in order to use a power supply cable or a communication cable to use a desk lamp or a personal computer in an office or the like, a cable such as a floor cable must be used. It was wired on a surface, or the existing floor was made into a double floor and wired so as to pass through the double floor. When laying cables on the floor, the cables hinder walking and have aesthetic problems.On the other hand, when double floors are used, the surface material of the floor is limited to tile carpet etc. For this reason, for example, a desired surface material such as a wooden floor material cannot be used, and there is a problem that construction work and repair work for changing the pattern are troublesome and costly.

[0003] Therefore, a wiring structure in which the cables are routed on the ceiling side instead of on the floor side is conceivable. In such a case, considering the rearrangement in the office or the like, the cables are moved from the ceiling side to a desired place on the floor side. It was desired that the structure be able to be taken out. In addition, in order not to impair the beauty of the office and to protect the cable from damage, it is preferable that the exposed portion of the cable be as small as possible so that wiring can be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned disadvantages of the prior art, and has as its object to move a cable from a ceiling to a floor, that is, a desired place on a lower side. And a cable wiring guide used in the cable wiring structure.

And a cable wiring guide that is detachably or movably attached to the location and that routes the cable drawn from the cable housing member to the floor side. As a result, the cable is laid down from an arbitrary position in the longitudinal direction of the cable housing member to a desired position on the floor side, that is, a lower side. Therefore, even if the desired place on the floor side is changed, as long as the place is located below the cable housing member in the longitudinal direction, the mounting position of the cable wiring guide to the cable housing member is changed, so that the stepless operation is performed. Can be dealt with. In this specification, the term “down wiring” is used not only for wiring that hangs down almost straight from the ceiling side to the floor side, that is, downward, but also while being bent or curved in the middle, The concept includes a case where wiring is performed so as to descend from the side to the floor side.

Further, like the cable wiring structure according to the second aspect of the present invention, the cable accommodating members are arranged so as to be connected to the ceiling side in a lattice pattern and are positioned parallel to each other. It is preferable that an auxiliary cable housing member is detachably or movably connected and fixed between the cable housing members. As described above, the presence of the auxiliary cable housing member allows the cable to be lowered and routed to an arbitrary location on the floor side.

Further, as in the cable wiring structure according to the third aspect of the present invention, the cable wiring guide is provided with a wiring protection cover for wiring down to the floor side and protecting the cables. It is desirable to be attached so that it can be attached.

Further, in the illustrated embodiment, the cable housing members 2 and 2 extending in the vertical direction and the horizontal direction are provided so as to communicate with each other at positions where they intersect with each other. However, they may simply be provided so as to extend in one direction, do not communicate with each other, and simply intersect vertically. Further, even though the cable housing members 2 are not necessarily arranged so as to be connected in a grid pattern, for example, all the cable housing members 2, 2 are arranged so as to be parallel and extend in the same direction. You may just be there.

In addition, the cable wiring structure K is provided between arbitrary cable housing members 2 and 2 which are positioned parallel to each other.
The auxiliary cable accommodation member 8 is detachably connected and fixed. As shown in FIG. 3, the auxiliary cable housing member 8 has a pair of projecting pieces 9, 9 projecting downward from one end and the other end in the longitudinal direction.

On the inner side surfaces of the protruding pieces 9, 9, female screw members 10, 10 provided with screw holes on the inner peripheral surface are fixed, and through holes 11 communicating with the screw holes of the female screw members 10, 10 are provided. , 11 are provided so as to penetrate the projecting pieces 9, 9 in the thickness direction. Thus,
The auxiliary cable accommodating members 8 are located parallel to each other,
Each of the cable housing members 2, 2 is placed on the upper surface of any of the arbitrary cable housing members 2, 2 in the longitudinal direction such that the cable housing members 2, 2 are bridged. And a male screw member 12 such as a bolt.
Is screwed into the female screw member 10, and the shaft end of the male screw member 12 protruding from the female screw member 10 is
By making contact with the inner surfaces of the side wall portions 5 of the respective cable housing members 2 and 2 so as to press them, the auxiliary cable housing member 8 is connected and fixed to an arbitrary position in the longitudinal direction of each of the cable housing members 2 and 2. A roller is provided on the lower surface of the auxiliary cable housing member 8 so that the roller rolls on the upper surface of the cable housing member 2 so that the auxiliary cable housing member 8 can move with respect to the cable housing member 2. May be attached. However, in such a case, it is desirable to provide a rail-shaped roller receiving portion on the upper surface of the cable housing member 2 to receive the roller.

On the other hand, as shown in FIGS. 2, 4 and 5, the cable wiring guide 3 extends vertically in an arc-shaped cross section so as to face the side wall 5 of the cable housing member 2. At the left and right of the upright wall portion 12 and the upper portion of the upright wall portion 12, the left and right 1 protrude from the upright wall portion 12 in the direction of the side wall portion 5 of the cable housing member, extend stepwise from the middle thereof, and extend a predetermined distance. Upper piece 13, 13 of the pair
And a lower piece formed by extending in the same direction as the side on which the upper pieces 13 and 13 are formed so as to become narrower from the lower portion of the upright wall portion 12 and then notching the front end. 14 is provided. The lower piece 14 is provided with side wall portions 15, 15 rising up a small distance at both ends formed in a straight line. The lower piece 14 has two through holes (not shown) penetrating vertically, and female screw members 16, 16 having screw holes communicating with the through holes are provided on the lower piece 14. It is provided on the upper surface side. Further, the lower piece 14 is provided with a long hole 17 extending vertically in the center thereof and penetrating vertically. The elongated hole 17 is provided with one end of a hanging member 19 such as a wire extending from the wiring protection cover 18 for hanging a wiring protection cover 18 to be described later. On the upper side of the lower piece 14, the one end is attached to the suspension member 20 and suspended. Thereby, the cable wiring guide 3 can hang the wiring protection cover 18 and the handling of the cable 1 becomes convenient.

The material and the shape of the wiring protection cover 18 are not particularly limited as long as the cable 1 can be protected, and an existing one may be used, but the wiring protection cover 18 is hung from the ceiling side to the floor side. It is desirable to take into account some aesthetic aspects as they are placed in a prominent position. For example, in the illustrated embodiment, the wiring protection cover 18 has a structure in which several types of cables 1 and 1 are separated for each same type of cable 1 so as not to interfere with each other.
Is used. That is, the wiring protection cover 18
In order to allow the hanging member 19 to pass through the center, a cylindrical portion 21 extending vertically in the center and extending a predetermined distance radially from the cylindrical portion 21 in a plan view, and then extending in a counterclockwise direction as required. It is composed of segment pieces 22 extending in a circular shape by a distance, and the segment pieces 22 are provided in multiple stages at regular intervals along the longitudinal direction of the cylindrical portion. Then, a plurality of cable accommodation sections 23, 23 are formed so as to surround the partitioning pieces 22, 22 (three in the illustrated embodiment).
The same kind of cable 1 is accommodated in 3 and 23.
In this way, the cable 1 is divided for each cable of the same kind, and the exposed portion is reduced.
Without being damaged from the outside, the aesthetic appearance will be improved.

However, for example, when it is desired to minimize the electric influence from another cable 1 such as a power cable, such as a LAN communication cable 1a used in network communication, the wiring protection cover 18 alone is sufficient. Not always. Therefore, the wiring protection cover 18 has a shielding plate 2 made of a magnetic material containing iron or the like.
4 is passed through just so as to fit into one of the cable accommodation sections 23.

Next, the details of the cable wiring structure K using the cable wiring guide 3 will be described.

First, the cable 1 accommodated in the cable accommodating member 2 is pulled out from the upper opening 7 substantially vertically above a desired place on the floor side, and is pulled down along the side wall 5 of the cable accommodating member 2. So that it hangs down. Then, the cable wiring guide 3 is set so that the upright wall 13 faces the side wall 5 of the cable housing member 2 while the cable 1 is being drawn therein, and the upper piece 13 is connected to the upper end of the cable housing member 2. Portion, that is, the cable housing member 2
(See FIG. 4). At this time, the upper piece 13 is hooked on the upper end of the bent portion 6 from the middle of the upper piece 13 until it is stepped down, and further extends after being stepped down, that is, the part on the tip side is upward. It extends to the opening 7 and acts as a holding piece 25 for holding the cable 1 pulled up from the cable housing member 2 from rising. With the provision of such a holding piece 25, the exposure of the cable 1 can be reduced. Further, by providing the holding piece 25 on the tip end side of the upper piece 13, it becomes easier to manufacture than providing the holding piece 25 separately and is advantageous in terms of cost. In order to prevent the cable 1 from being damaged, a cable damage prevention cover 26 made of a synthetic resin is attached to the pressing piece 25 so as to cover the periphery thereof.

The term “to pull in the cable 1” as used herein means that the cable 1 is connected to the left and right 1
From the space 27 between the pair of upper pieces 13, 13, a gap 28 formed between the inner surface of the upright wall 13 and the side wall 5 of the cable housing member 2, and the upper surface of the lower piece 14 and the cable housing member 2 The cable 1 is passed through the cable routing guide 3 so as to hang down through a gap 29 formed between the cable 1 and the lower surface of the cable 1 (see FIG. 5). By providing such gaps 28 and 29, the cable 1 can be taken out to a desired place on the floor side so as to be guided through the gaps 28 and 29. But cable 1
The cable 1 may pass through the lower piece 14 so that the cable 1 passes through the gap 28 formed between the inner surface of the upright wall 13 and the side wall 5 of the cable housing member 2 and hangs downward. Possible cable passages may be provided.

By the way, the cable 1 passing through the gap 28 formed between the inner surface of the upright wall 13 and the side wall 5 of the cable housing member 2 has the upright wall 12 with respect to the side wall 5 of the cable housing member 2. By being able to face each other so as to surround the front side thereof, that is, by contacting the left and right ends of the upright wall portion 12 with the side wall portion 5 of the cable housing member 2,
It is hidden from the outside, and the exposure of the cable 1 is suppressed as much as possible. For this reason, the cable 1 is protected from damage, and the appearance is improved. Especially on the aesthetic side,
Since the outer surface of the upright wall surface 13 of the cable wiring guide 3 protrudes in a curved shape, it is possible to give a more comfortable impression to a viewer than to be angular.
Of course, the shape of the outer surface of the upright wall 13 is determined based on the premise that the gaps 28 and 29 for the cable 1 to pass are provided, in addition to the aesthetic surface, and the ease of handling. This may be determined in consideration of the above, and is not limited to the illustrated embodiment.

Next, in order to fix and attach the cable wiring guide 3 to the cable housing member 2, a male screw member 30 with a knob is screwed into the female screw member 16 provided on the upper surface of the lower piece 14 from below. Then, the lower end of the cable housing member 2 is pressed between the lower piece 14 and the upper piece 13 by pressing the lower surface of the cable housing member 2 with the shaft end of the male screw member 30. However, the fixing means for fixing the cable wiring guide 3 to the cable housing member 2 includes the female screw member 16 and the male screw member 3.
It is not limited to the combination with 0. For example,
If the lower piece 14 of the cable wiring guide 3 has a sufficient thickness to provide a screw hole, the female screw member 16 may not be necessary only by providing such a screw hole. Also, for example,
As the fixing means, a cam mechanism that provides an eccentric cam or the like on the upper surface of the lower piece 14 may be used, or a link mechanism may be used. Furthermore, the fixing means may be provided not on the lower piece 14 but on the upper piece 13. However, since the work of attaching the cable wiring guide 3 to the cable housing member 2 is usually performed overhead, it can be said that the fixing means is preferably provided on the lower piece 14 in terms of work.

In this manner, the cable wiring guide 3 can be easily detachably attached to an arbitrary position in the longitudinal direction of the cable housing member 2. Therefore, even if the desired place on the floor side is changed, the place is changed to the cable housing member 2.
Can be easily handled by changing the attachment position of the cable wiring guide 3 to the cable housing member 2. Further, if the auxiliary cable housing member 8 is used, such an auxiliary cable housing member 8 is connected and fixed to arbitrary positions in the longitudinal direction of the cable housing members 2 and 2 which are positioned parallel to each other.
Regardless of where the desired place is located on the floor side, the cable 1 can be taken out to that place.

Thereafter, the cable 1 exits from a portion of the cable wiring guide 3 where the front portion of the lower piece 14 is cut off, and is passed through so as to be accommodated in the wiring protection cover 18. It is pulled out from the lower end of the protective cover 18 and is provided on a desk or a partition 31 for surrounding or partitioning the desk (in the illustrated embodiment, a partition panel connecting corner member for connecting the partition panels). The wiring is wired into the wiring duct portion (or wiring space chamber) 32. Due to the wiring duct portion (or the wiring space chamber) 32, the exposure of the cable 1 is suppressed even on the floor side, and the cable 1 is reliably guided and wired to a terminal location such as electricity.

The present invention is not limited to the embodiment described above, and various other modifications are possible. For example, the holding piece 26 for holding the cable 1 from rising is formed at an appropriate position on the upper part of the upright wall 13 separately from the upper piece 13 even if it is not provided on the tip side of the upper piece 13. But the number is 2
The number is not limited to one, and may be one, or three or more. Further, for example, when the cable 1 does not rise so much, the holding piece 26 is not necessarily required if the cable 1 is merely pulled into the cable wiring guide 3.

The cable wiring guide 3 is provided so that the upper piece 1 can be moved in the longitudinal direction of the cable housing member 2.
3, a roller that rolls on the bent portion 6 may be provided at a position facing the bent portion 6. Of course, also in this case, the cable wiring guide 3 is fixed by the fixing means at an arbitrary position in the longitudinal direction of the cable housing member 2.

In the illustrated embodiment, an example has been described in which the cable 1 pulled out from the cable housing member 2 is wired by the cable wiring guide 3 so as to hang almost straight down to the floor side, that is, downward. However, the cable 1 may be wired such that it does not necessarily hang down straight, but bends or curves in the middle and goes down to the floor side.
