[Problems to be solved by the invention]
By the way, desks are sometimes arranged face-to-face and side-by-side for effective indoor use. When such a face-to-face arrangement is performed, power lines, communication lines, and the like can be relatively easily wired using a wiring duct in the lateral direction. On the other hand, when wiring between desks facing each other, if you try to pass the wiring through the wiring duct of the facing desk, draw out the power line or communication line from one end of the wiring duct of one desk, and After the wiring is routed on the surface, it is necessary to draw the wiring from one end of the wiring duct of the other desk into the wiring duct. For this reason, when such a desk is arranged face-to-face, the power line and the communication line, etc., go out of the wiring duct, such as the floor, from the wiring duct. There was a problem that it was trapped. In addition, since power lines and communication lines are exposed on the floor, it is not only unsightly, but also the feet tend to be complicated when using a desk, and the safety is reduced by stepping on casters such as chairs and wagons. It became something.
[0005]
In view of such problems, it is conceivable to double the floor and wire power lines and communication lines between the slab and the floor, but this is not only expensive at the time of installation, but also, for example, the arrangement of desks In the case of changing the wiring, it was necessary to turn over the floor to carry out wiring change work, which increased the work time and increased costs.
[0006]
In view of the above problems, the present invention is to provide a desk that can easily wire a power line, a communication line, and the like between facing desks.
[0007]
[Means for Solving the Problems]
That is, the desk according to the present invention has a wiring passage having an upper and a front-rear opening communication portion capable of communicating with a wiring space arranged near the rear edge of the top plate and an external space in the facing direction. A desk provided with a hole in a part of a rear wall of a wiring space, wherein the wiring through-hole is detachably provided with a closing member for closing at least an upper part of the communication part.
[0008]
According to such a configuration, the external space and the wiring space in the facing direction can communicate with each other through the communication portion. It can be routed outside. In addition, since at least the upper portion of the communication portion is removably closed by the closing member, it is possible to prevent the inconvenience that the article falls into the wiring hole during use.
[0009]
In order to smoothly take out the wiring from the wiring space to the external space and to make the communication part inconspicuous from the outside to improve the appearance, it is preferable that the communication part has an inclined surface that is inclined rearward and downward.
[0010]
In order to use the closing member in common regardless of the length of the communicating portion, the closing member comprises a beam member which is attached over substantially the entire upper end of the back member attached to the back end of the top plate. Is preferred.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

A back panel 5 as a back member is mainly formed, a wiring hole 11 is formed at an upper end 5A of the back panel 5, and a beam member 11B as a closing member is mounted on the upper end thereof so as to be covered. I have. In this embodiment, the wiring hole 11 is arranged at the center of the upper end 5A.
[0013]
A duct cover 6 that opens and closes a gutter 9 that forms a wiring duct space DS for holding wiring provided on the rear panel 5 is provided on the rear end side of the top plate 4 so as to open and close. Attached in between. The duct cover 6 is made of synthetic resin and has a flat plate shape. In this embodiment, the duct cover 6 is divided into left and right covers 6a and 6b and a central cover 6c. The left and right covers 6a, 6b are provided with cutout holes 61 which are always closed by lids 61a slidably attached to one side end thereof. The duct cover 6 is attached so that its upper surface is substantially flush with the upper surface of the top plate 4 and the upper surface of the beam member 11B attached to the upper end 5A of the back panel 5, and is substantially together with the upper surface of the beam member 11B. The upper surface of the top plate 4 of the desk 1 is extended. The left and right side ends of the wiring duct space DS are closed by side covers 10 having an angle shape in a front view.
[0014]
The side cover 10 has an inverted L-shape when viewed from the front, and the lower half of the side surface is formed to be separable. That is, when the side cover 10 is detached from the attachment portion of the desk 1, the side cover 10 can be separated into the side cap 101 and the upper surface member 102 constituting the lower half of the side surface. On the upper surface portion of the upper surface member 102, a double-opening lid is attached in a downward direction when attached to the desk 1. By removing the side cap 101, the wiring in the wiring duct space DS can be taken out in the lateral direction of the desk 1. That is, when the desks 1 are arranged in the horizontal direction, the wiring duct spaces DS of the adjacent desks 1 can communicate with each other via the opening of the side cover 10 from which the side cap 101 is removed.
[0015]
The upper end portion 5A of the rear panel 5 has its depth dimension (width dimension in the front-rear direction) set smaller than the width of the duct cover 6, and has a wire panel 11 at both ends through the wiring holes 11. A corner cover 8 fixed to the sleeve 3 is connected. Thereby, the upper end portion 5A functions as a rear wall near the upper edge of the wiring duct space DS. The height of the front surface 5d of the upper end portion 5A facing the wiring duct space DS is set to a size in which a related piece 11Bb provided on the inner surface of the front wall portion 11Ba of the beam member 11B described later is engaged. The upper surface of the corner cover 8 is provided with a square hole for mounting an option such as a desktop panel, and a post cap made of a substantially rectangular flat plate is provided near the upper end of the square hole. The square hole is closed by being engaged with the groove.
[0016]
As shown in FIG. 2, the wiring hole 11 is formed by cutting off a part of the upper end 5A of the rear panel 5 and opening or communicating with the opening 11A, which is open in the front-rear direction and the upward direction of the desk 1, and the beam. It is constituted by a member 11B.
[0017]
In this embodiment, since the communication portion 11A is elongated, a support 11Aa is provided substantially at the center in the length direction of the communication portion 11A to support the beam member 11B, and the decorative members 7A are provided at both ends thereof. Is provided with a connecting column 11Ab for the end portion of the light emitting element. Therefore, the substantial communication part 11A is divided into two parts by the support 11Aa.
[0018]
The columns 11Aa and the connection columns 11Ab are made of, for example, sheet metal, and have the same height as the upper surface 5e of the upper end 5A, and are fixed to the rear panel 5. At the upper end of the front surface of the support column 11Aa and the connection column 11Ab facing the top plate 4, there is provided a mounting groove 11Ac into which the related piece 11Bb of the front wall portion 11Ba of the beam member 11B is inserted, and the rear surface is a rear panel. 5 has an inclined surface 11Ad along the upper end inclined surface 5a, a vertical surface 11Ae vertically continuous from the upper end of the inclined surface 11Ad, and a downward surface 11Af horizontally continuous from the upper end of the vertical surface 11Ae. That is, the pillar 11Aa and the connecting pillar 11Ab are pillars having a concave portion having a downward inclined surface 11Ad on the rear surface. When the beam member 11B is attached to the communication portion 11A, a space defined by the vertical surface 11Ae and the downward surface 11Af becomes an opening in the wiring hole portion 11, and the communication portion 11A is inclined rearward and downward as described below. The upper edge inclined surface 5a is provided. Note that when the length of the communication portion 11A is short, that is, the beam member 11B is not bent when the beam member 11 is attached to the communication portion 11A, or the beam member 11B is not easily deformed when pressed from above. In this case, the support 11Aa is unnecessary.
[0019]
The beam member 11B attached to such a communication portion 11A is made of, for example, a synthetic resin and has a basically channel shape. As shown in FIG. 3, the beam member 11B is used to attach the duct cover 6 to the front wall portion 11Ba. A related piece 11Bb having a groove 11Bc and protruding rearward on the inner surface thereof, and a lower surface of the rear wall 11Bd formed by being bent toward the front side, and a lower surface of the connecting column 11Ab and the column 11Ac. 11Af and the engaging edge 11Be which engages. The beam member 11B has a length extending from one end to the other end of the upper end 5A, and also functions as a mounting member for the duct cover 6.
[0020]
In the above configuration, when the desk 1 is in use, the beam member 11B is attached to the upper end 5A. That is, the beam member 11B engages the associated piece 11Bb of the front wall portion 11Ba with the upper end portion 5A, engages with the associated groove 11Ac of each of the connecting column 11Ab and the column 11Aa, and sets the engaging edge 11Be of the rear surface at the upper end. The portion 5A, the connecting pillar 11Ab, and the supporting pillar 11Aa are engaged with the downward facing surfaces 5f, 11Af, respectively. When the beam member 11B is attached to the upper end portion 5A7 in this manner, the opening of the communication portion 11A exists at the position of the wiring hole 11 on the rear surface side of the decorative member 7, but the opening of the communication member 11B is The upper edge inclined surface 5a of the back panel 5 has a structure in which the upper edge inclined surface 5a faces the engaging edge 11Be of the wall portion 11Bd, and the upper end 5aa of the upper edge inclined surface 5a which is a substantial opening is located on the front side of the rear surface 5c of the rear panel 5. , The rear appearance is difficult to be recognized (shown in FIG. 4). Therefore, in the case where the power line and the communication line are not drawn out using the wiring hole 11, it is possible to eliminate discomfort even if the power line and the communication line are arranged in the same row as a normal desk without the wiring hole 11 (FIG. 4).
[0021]
On the other hand, when desks of the same type are arranged face-to-face, the wiring holes 11 of the desks 1 face each other as shown in FIG. In the case of this embodiment, the desks 1 are not necessarily connected to each other because the wiring hole 11 is located at the center in the width (left and right) direction of the desk 1 and the length of the opening of the communication section 11A is relatively long. Even if the both end portions do not coincide in the width direction, the wiring through holes 11 partially overlap each other.
[0022]
After arranging the desk 1 in this manner, the beam member 11B is removed from the upper end 5A. As a result, the communication portion 11A of each desk 1 is exposed with its upper side open. In this case, if the duct cover 6 is removed, the state where the wiring duct space DS and the communication portion 11A communicate with each other can be reliably grasped. Then, after confirming, among the wirings in the wiring duct space DS, the wiring that needs to be routed to the desk 1 that is placed facing the desk, the wiring WR is transferred to the desk that is placed facing the desk 1 through the respective wiring holes 11. It is routed to the first wiring duct space DS. In the case of the desk 1 of the same type, since the back panel 5 is almost in close contact, the wiring holes 11 are also in close contact with each other on the back surface. Therefore, it is possible to minimize the slack of the wiring extended between the desks 1.
[0023]
After the wiring is completed, the beam member 11B is attached to the upper end 5A, and the duct cover 6 is attached. When the beam member 11B is attached to the upper end portion 5A, a space as a communication portion is formed between the engaging edge 11Be of the beam member 11B and the upper end inclined surface 5a of the rear panel 5, so that the wiring hole portion is formed. The wiring drawn from 11 is not compressed by the beam member 11B. In addition, since the wiring in the wiring duct space DS reaches the wiring duct space DS of the desk 1 which is directly opposed to the wiring duct space DS via the communication portion 11A, the wiring is in the lower limb space or the floor of the desk 1. It is possible to prevent the wiring from being exposed. Therefore, it is possible to avoid stumbling on these wires and pulling them with a shock or stepping on casters such as a chair or a wagon, and thus the wires can be reliably protected.
[0024]
Further, when a plurality of desks 1 are arranged in parallel in the horizontal direction and the desks 1 are arranged facing each other, the wiring duct space DS and the wiring hole 11 of each desk 1 are used. Thus, wires such as power lines and communication lines can be routed without having to crawl on the floor. Since such wiring work can be performed from the upper side of the desk 1, for example, the work efficiency can be increased as compared with the work in the lower limb space of the desk 1, and the burden on the operator can be reduced.
[0025]
The present invention is not limited to the embodiment described above.
[0026]
In the above-described embodiment, the beam member 11B is attached over the entire length of the upper end portion 5A including the upper portion of the communication portion 11A. However, the beam member 11B may be attached only to the communication portion 11A. Good. In this case, when the height of the support 11Aa and the connection pillar 11Ab is set to be lower by the thickness of the beam member 11B, and the beam member 11B is attached to the support 11Aa and the connection pillar 11Ab, the upper surface and the upper end of the beam member 11 are formed. The upper surface of 5A is flush with the upper surface.
[0027]
The formation position and the length (size) of the wiring through-holes 11 may be appropriately set, and when the desk 1 is arranged to face, the positions where the wiring through-holes 11 at least partially overlap each other. Is set, and the length of the overlapping portion is set so as to be as long as possible. By adopting such a configuration, even when desks having different dimensions other than the height, for example, desks having different top plate sizes are arranged face-to-face, the wiring holes 11 communicate with each other. be able to. Further, the wiring hole portion 11 does not need to be provided at one place, and may be provided at a plurality of places at intervals.
[0028]
In the above-described embodiment, the desk having the sleeve has been described. However, the above-described wiring hole 11 can be applied to a case where the top plate 4 is supported by the two side panels 2. It is.
[0029]
In addition, the specific configuration of each unit is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
