Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition wiring device which allows a cable to be inserted through a plurality of connected partitions.

[0002]

2. Description of the Related Art A so-called low partition having a height of about a half of a ceiling is adopted as one of partition walls for partitioning a living space such as an office floor into individual working spaces. This partition has a frame formed by connecting a pair of columns with a horizontal rod. A plurality of frames are linearly connected. One or a plurality of panels divided in the vertical direction of the columns are detachably attached to one and the other surfaces of the frame.

In recent years, many OA devices have been installed in a work space partitioned by such partitions. For this reason, a large amount of cables such as power supply wiring, communication wiring, and ground wiring are exposed, which causes a problem that the appearance is deteriorated.

One of the means for preventing the cable from being exposed and improving the appearance is a partition wiring device that allows the cable to be inserted over a plurality of partitions to be connected. Conventional devices of this type include, for example, Japanese Patent Laid-Open Nos. 8-165726 and 9-
There is one disclosed in Japanese Patent Publication No. 1375331. In each of these devices, a recess is formed in the panel mounting surface of the column, and a wiring insertion hole is formed by the recess and the panel.

Therefore, according to these devices, it is not necessary to insert the cable from the tip into the through hole, unlike the case where the through hole whose peripheral portion is closed is simply formed in the support column. That is, the cable can be housed in the recessed portion opened by removing the panel from the direction perpendicular to the mounting surface, and the wiring workability can be improved.

[0006]

However, in the above-mentioned conventional cable connecting device for partitions, the recesses for forming the wiring insertion holes are formed in the support columns. For this reason, the cross-sectional area of the support pillar is reduced at the recessed portion forming portion, which may reduce the strength of the support pillar.

Further, in order to prevent such a decrease in the strength of the column, a structure in which the column is integrally formed with a main column and a pair of sub columns sandwiching the main column is considered. In such a composite column, it is possible to divide a proper position of only the sub column to form a recess. However, in such a composite column, although strength reduction can be prevented, it is not easy to manufacture and the width of the column in the composite direction becomes large, which is an obstacle to thinning the partition.

Further, in the above-described conventional cable connecting device for partition, the position of the wire insertion hole cannot be changed because the recess is formed in the support. On the other hand, if a plurality of wiring insertion holes are provided in the vertical direction of the support in advance, the use position of the wiring insertion hole can be changed, but the above-mentioned decrease in the strength of the support becomes more remarkable.

The present invention has been made in view of the above circumstances, and provides a partition wiring device in which the strength of the supporting column is not reduced, the partition is not thinned, and the position of the wiring insertion hole can be changed. The purpose is to do.

A pair of upper and lower horizontal rods 3 and 3 are connected to the pair of columns 1 and 1 shown in FIG. 2, and the columns 1, 1 and the horizontal rods 3 and 3 form a gate-shaped frame 5. ing. The space sandwiched between the pair of columns 1 and 1 forms a wiring space 7.

As shown in FIG. 1, a panel 9 which is divided into a plurality of columns 1 and 1 in the vertical direction is detachably attached to one and the other surfaces of the frame 5. The columns 1, 1 and the panel 9 form a partition 10. As shown in FIG. 3, at least one of these panels 9 is a panel 13 with an insertion hole in which vertical frames 11 are formed at both left and right ends of the back surface. When the panel 13 with the insertion hole is attached to the frame 5, the vertical frame 11 comes into contact with the attachment surfaces 1a of the columns 1 and 1.

The panel 9 and the panel 13 with the insertion hole are made of a metal material, for example, in the panel body. When the panel body is made of a metal material, the vertical frame 11 is preferably made of an insulating material having elasticity. As the insulating material having elasticity, a resin material such as rubber or soft vinyl can be preferably used.

Panel 13 with an insertion hole according to this embodiment
The panel body is formed of a metal material in a U-shaped cross section. A vertical frame 11 made of a resin material, which is formed separately, is fixed to both ends of the panel body by a locking structure using locking claws, or by screws, rivets or the like.

A vertical frame 1 that abuts the mounting surface 1a of the columns 1 and 1.
On one contact surface 11a, for example, two upper and lower concave grooves 15 are formed. The groove 15 crosses the vertical frame 11 and has both ends open to the wiring space 7 and the outside 8. Therefore, as shown in FIG. 5, when the panel 13 with the insertion holes is attached to the frame 5, a space surrounded by the concave groove 15 and the attachment surface 1a is formed between the vertical frame 11 and the columns 1 and 1. Will be done. This space serves as a wiring insertion hole 17 that connects the wiring space 7 and the outside 8.

The panel 13 with the insertion holes can be attached to the frame 5 by replacing the other upper and lower panels 9. The upper and lower end portions of the contact surface 11a of the vertical frame 11 are shown in FIG.

1 is elastically movable up and down, and is rotatable by a horizontal shaft 23, for example. The upper hook 21 is biased in the counterclockwise direction a in FIG. 4 by a biasing means (not shown).
The upper hook 21 is restricted from rotating counterclockwise from the vertical position shown in FIG. 4 by a stopper (not shown). Therefore, the upper hook 21 is rotated in the clockwise direction b against the urging force and then returned to the vertical position by the urging means when the external force is released.

Plural locking holes 25 (see FIG. 2) are formed in the columns 1 and 1 in the vertical direction. The locking holes 25 are arranged so that all the panels 9 and the panel 13 with the insertion holes can be replaced and attached at arbitrary positions.

The panel 9 and the panel 13 with the insertion hole are attached by locking the lower hook 19 in the lower locking hole 25 and pushing the upper hook 21 into the upper locking hole 25.
The upper hook 21 is pushed into the upper locking hole 25 to rotate against the biasing force, and then returns to the vertical position again to lock in the locking hole 25. As a result, the panel 9 and the panel 13 with the insertion hole are attached to the lower hook 19 and the upper hook 2.
It is removably attached to the frame 5 via 1.

Panel 9 according to this example, panel 1 with an insertion hole
No. 3 exemplifies that the heights in the vertical direction are different,
These panels may be formed at the same height. In addition, 27 of FIG. 1 is a skirting board detachably attached to the columns 1 and 1.

At the positions of the columns 1 and 1 to which the panel 13 with the insertion hole is attached, a cable support 29 is provided corresponding to the wiring insertion hole 17. The cable support 29 is
It is formed in an upward U shape having a pair of parallel standing pieces 29a, 29a. The cable supporting member 29 is similar to the above-mentioned panel in that the columns 1 and 1 are formed by hooks and locking holes.
It can be detachably attached to the surface of the wiring space 7 side. That is, the cable support 29 can be interchangeably attached at any position in the vertical direction of the column.

As shown in FIG. 2, in the cable support 29 attached to the columns 1 and 1, the upright pieces 29a and 29a project outward from the attachment surface 1a of the columns 1 and 1. Standing piece 29
A cable insertion gap s is formed between a and 29a and the mounting surface 1a. Further, the upright pieces 29a, 29a protruding outward from the mounting surface 1a come into contact with the back surface of the panel 13 with the insertion hole.

In the partition wiring device 31 having such a configuration, when the cable 33 is routed between the plurality of connected partitions 10, the insertion hole-equipped panel 13 is not attached. That is, in this state, as shown in FIG. 6, the wiring space 7 and the cable support 29 are exposed to the outside 8.

In this state, the cable 33 is inserted into the cable supporting member 29 from above and supported from one surface of the partition 10. As shown in FIG. 6, in the connecting portion 35 between the partitions 10, the cable 33 is routed outside the columns 1 and 1 through the cable insertion gap s (see FIG. 2). The cable 33 may be an optical cable in addition to power supply wiring, communication wiring, and ground wiring.

When the wiring of the cable 33 is completed in this way, the panel 13 with the insertion holes is attached to the panel non-attached portion by the above-mentioned procedure.
