【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a left side view of a central longitudinal section of a desk to which the present invention is applied (hereinafter, the direction will be described with the left side of FIG. 1 as the front), and a pair of left and right legs (only the right side is shown) (1) is composed of a horizontal leg (2), a top plate supporting rod (3), a rear support (4) and an intermediate support (5), and is integrally formed integrally in a forward U-shape.

A reinforcing rod (6) having a substantially hexagonal cross-section is laid horizontally on the same plane as the upper surface of the top plate supporting rod (3) in the rearward direction between the left and right top plate supporting rods (3). There is. The vertically elongated rectangular opening (7) formed between the rear strut (4) and the intermediate strut (5) is covered by a pair of left and right side plates (8).

(9) is a top plate placed on the upper surfaces of the left and right top plate supporting rods (3) and the reinforcing rods (6). Between the left and right rear columns (4), the curtain plate (10) fits into the vertically elongated holes (4a) formed from the upper end to the lower side, which are formed on the inner side surfaces of the columns (4) at both ends thereof. Therefore, it is installed.

At this time, a required gap (S) is formed between the upper end of the curtain plate (10) and the rear lower end surface of the top plate (9).

(D) is a duct unit, which is configured as follows. That is, as shown in an enlarged manner in FIGS. 2 and 3, the supporting substrate (11) in the duct unit (D) is integrally molded with a synthetic resin in a horizontally long rectangular shape, and the left and right sides thereof have left and right legs (1). The length between the rear end of the leg (1) and the reinforcing rod (6) is approximately the length that can be accommodated between the legs.

A hinge part (12) is formed in the left and right directions toward the rear of the support substrate (11) by making the plate thickness thin over a required width, and the support substrate (11) is a hinge. The part (12) can be bent up and down around the center.

On the upper surface of the front end portion of the support substrate (11), a pair of front and rear locking pieces (13) (13) elastically engageable with the reinforcing rod (6) are directed upward in the left-right direction. It is lined up. The continuous position of the locking piece (13) from the rear end of the support base plate (11) is substantially equal to the dimension from the rear end of the leg (1) to the fixing position of the reinforcing rod (6). (11a) is a grip for engaging and disengaging.

A pair of front and rear partitions (14) and (14) which are parallel to each other are continuously provided on the upper surface of the intermediate portion of the support substrate (11) in an upward direction facing the left-right direction.

At the rear end of the support substrate (11), a closing piece (15), which is slightly inclined forward and whose upper end is bent forward in an arc shape, is continuously provided upward. The upper and lower dimensions of the closing piece (15) are formed to have almost the same length as the closing pillar (15) so as to close the gap (S) between the rear support column (4) and the top plate (9), and the front portion. When pressed to, it can be elastically deformed forward with the base end as the center.

On the lower surface of the support substrate (11) rearward of the hinge portion (12), a reinforcing piece (16) that can come into contact with the inner surface of the upper end of the curtain plate (10) is continuously provided downward. . Similarly, behind the reinforcement piece (16), a retaining piece (17) that can be fitted in a recessed groove (10a) formed in the upper end surface of the curtain plate (10) facing in the left-right direction is continuously provided downward. Has been done.

When the duct unit (D) having the above-mentioned configuration is mounted just below the rear end of the top plate (9), before the curtain plate (10) is mounted between the legs (1), the support substrate (11) is attached. After pre-fitting the retaining piece (17) from the side into the groove (10a) at the upper end of the curtain plate (10) from the side, connect the both ends of the curtain plate (10) to the vertically long holes of the rear support column (4). It suffices to fit it into (4a) and fit both locking pieces (13) of the support substrate (11) into the reinforcing rod (6) from below.

As a result, in the support substrate (11), the inwardly bent V-shaped bent portions of both locking pieces (13) are elastically engaged with the outwardly facing top surfaces of the hexagonal reinforcing rods (6). By this, the space between the lower surface of the top plate (9) and the support substrate (11) at the time of mounting becomes a storage part (18) for the wiring cable (C) such as a power cord. .

As described above, in the above embodiment, the closing piece (15) provided at the rear end of the supporting board (11) in the duct unit (D) is as shown by an imaginary line in FIG. The wiring cable (C) and its extra length cable can be pushed into the storage part (18) from the rear of the desk by elastically deforming it slightly forward. Moreover, after the storage or wiring, the gap (S) is properly covered by the closing piece (15), so that the wiring cable (C) is not exposed from the outside and the appearance is improved.

On the other hand, when the engagement piece (13) of the support substrate (11) and the reinforcing rod (6) are disengaged, the support substrate (11) is moved downward with the hinge portion (12) as the center. Since it can be rotated and tilted, the wiring cable (C) and the extra length cable can be easily stored or wired in the storage section (18) from the front of the desk, and also inserted from the rear of the desk. The wiring cable (C) can be easily routed to other places. At this time, if the wiring cable (C) is located between the two partition parts (14), it can be restrained from moving inadvertently in the front-rear direction.

Since all the members in the duct unit (D) are integrally connected to each other, the number of parts is extremely small and no special tool is required for mounting on the desk. And work efficiency are greatly improved.

The present invention is not limited to the above-mentioned embodiment, but can take various modes. For example, the support substrate (11) and the reinforcing rod (6) may be engaged with each other as shown in FIG. 4 or 5.

That is, in the structure shown in FIG. 4, a locking groove (6a) facing in the left-right direction is formed on the front and rear surfaces of the reinforcing rod (6) having a substantially square cross section, and the locking groove (6a) is formed in the locking groove (6a). The inward projections (13a) of both locking pieces (13) erected upright on the support substrate (11) are detachably engaged with each other.

In addition, as shown in FIG. 5, a proper number of locking holes (19) are formed on the lower surface of the reinforcing rod (6) having a square cross section, and the supporting holes are supported in the locking holes (19). A resin fastener (20) fixed to or integrally molded with the upper surface of the substrate (11) is detachably engaged with the resin fastener (20). INDUSTRIAL APPLICABILITY The present invention can be easily applied to a desk or the like in which the reinforcing rod (6) faces the front-rear direction.
