Description

The present invention relates to a desk with a wiring duct on the opposite end of the top plate.

Various types of wiring ducts are known that are provided on the opposite end of the tabletop, but some have also been developed that have wiring ducts that can be flipped back and forth to guide the wiring in different ways (see, for example, Patent Document 1).

However, in conventional devices, the attachment sites for attaching the wiring duct to the desk body in the first usage mode and the attachment sites for attaching the wiring duct to the desk body in the second usage mode are different, which increases the number of attachment sites required on the desk body, making the structure more complicated and the assembly work more cumbersome (first issue).

In addition, with this type of desk, there may be requests to change the installation position of the wiring duct in the front-to-rear direction depending on whether or not the desk is facing the other person or the installation of a desktop panel. In such cases, there is a problem that with conventional desks, the arrangement of the installation points on the desk body becomes even more complicated (second issue).

First Embodiment (FIGS. 1 to 18)
Hereinafter, one embodiment of the present invention (embodiment 1) will be described with reference to FIGS.

As shown in Figs. 1 to 3 and 7 to 11, the desk D of this embodiment (which may be referred to as "desk D1" when it is necessary to distinguish this desk D from another desk D2 of the same structure) comprises a pair of left and right legs 1 having a first mounting point 1a and a second mounting point 1b at different heights, a top plate 2 that can be selectively attached to either the first or second mounting point 1a or 1b, and a shelf plate 3 that is attached to the first mounting point 1a while the top plate 2 is attached to the second mounting point 1b. The top surface 2a of the top plate 2 is configured to be flush and continuous with the top surface 2a, 3a of the top plate 2 or shelf plate 3 of the adjacent desk D2 of the same structure.

In more detail, as shown in Figs. 1 to 3 and 7 to 11, each leg 1 comprises a front leg column 11, a rear leg column 12, an upper connecting member 13 connecting the upper ends of the front leg column 11 and the rear leg column 12, and a lower connecting member 14 connecting the lower ends of the front leg column 11 and the rear leg column 12. The front leg column 11 is tilted backwards and the rear leg column 12 is substantially vertical, with the upper and lower connecting members 13 and 14 being horizontal. The first mounting location 1a is set at the upper end of the leg 1, and each first mounting location 1a is provided with, for example, three nuts n1 for mounting a top plate and two nuts n3 for mounting a shelf plate. Specifically, each nut n1, n3 is embedded in the front and rear leg columns 11, 12 with the screw holes open to the inner surface side of the leg 1. The second mounting locations 1b are set at a certain distance below the first mounting locations 1a, and each of the second mounting locations 1b is provided with, for example, three nuts n2 for mounting the tabletop. Specifically, each nut n2 is embedded in the front and rear leg columns 11, 12 with a screw hole opening on the inner side of the leg body 1, similar to the three nuts n1 provided at the first mounting locations 1a. Furthermore, the leg body 1 is provided with a third mounting location 1c for mounting the shelf board 3 at a position near the lower end when the tabletop 2 is attached to the first mounting location 1a. At this third mounting location 1c, a nut n4 with a screw hole opening on the inner side of the lower connecting member 14 of the leg body 1 is provided. As described above, the tabletop 2 can be selectively attached to either the first or second mounting location 1a, 1b. The front leg columns 11 and rear leg columns 12 are flattened prism pipes with a rectangular cross section, with the thickness dimension in the left-right direction set to be smaller than the width dimension in the front-rear direction. The upper connecting member 13 and lower connecting member 14 described above are shaped so as not to protrude from the outer surfaces 11x, 12x of the leg columns 11, 12, so that the outer surfaces 11x, 12x of the leg columns 11, 12 of another desk D2 having the same structure can be closely attached to the outer surfaces 11x, 12x of these leg columns 11, 12. The upper connecting member 13 is provided with a notch 13a.

As shown in Figs. 1 to 4 and 7 to 11, the tabletop 2 comprises a rectangular wooden tabletop body 21 and a tabletop support bracket 22, which is a tabletop support member that supports the tabletop body 21 and is attached to both left and right ends of the underside 21c of the tabletop body 21. The tabletop support bracket 22 comprises a bracket body 221 arranged on the side of the tabletop body 21 and an attachment portion 222 that extends from the lower edge of the bracket body 221 and is attached to the underside 21c of the tabletop body 21. The bracket body 221 has a screw insertion hole 22a corresponding to the nuts n1 and n2 for attaching the tabletop at the first and second attachment points 1a and 1b of the leg 1. Then, by screwing a bolt (not shown) that has passed through the screw insertion hole 22a into the nuts n1 and n2 for attaching the tabletop, the tabletop 2 can be detachably attached to either the first or second attachment point 1a or 1b.

The tabletop 2 attached to the first attachment point 1a is held in a high-level position (H) as shown in Figures 1 to 4 and 7, which is suitable for use when the user is standing or sitting on a high-type chair, and the tabletop 2 attached to the second attachment point 1b is held in a low-level position (L) as shown in Figures 8 to 11, which is suitable for use when the user is sitting on a normal office chair. In this embodiment, the top surface 2a of the tabletop 2 held in the high-level position (H) is held at a height position 900 mm above the floor surface, and the top surface 2a of the tabletop 2 held in the low-level position (L) is held at a height position 720 mm above the floor surface. These values are merely examples, and the design can be modified as appropriate. When the top plate 2 is attached to the first attachment point 1a, the shelf plate 3 is attached to the third attachment point 1c as shown in Figures 1 to 4 and 7, and when the top plate 2 is attached to the second attachment point 1b, the shelf plate 3 is attached to the first attachment point 1a as shown in Figures 8 to 11. The shelf plate 3 attached to the third attachment point 1c can function not only as a shelf plate, but also as a footrest. In that case, it is desirable to attach a cover with a U-shaped cross section (not shown) to the top surface 3a of the shelf plate 3.

The shelf 3 is made of sheet metal with both front and rear edges and both left and right edges extending downward. The front and rear edges of the shelf 3 are provided with a front frame 31 and a rear frame 32 extending downward, respectively, as shown in Figures 3, 7, 10, and 11, and the left and right edges of the shelf 3 are provided with side plates 33 extending downward. The side plates 33 are formed with a notch 33a for inserting a screw. As shown in Figures 10 and 11, when the top plate 2 is attached to the second attachment point 1b, the shelf 3 can be detachably attached to the first attachment point 1a by screwing a bolt (not shown) that has passed through the notch 33a for inserting a screw into two nuts n3 for attaching the shelf at the first attachment point 1a. On the other hand, when the top plate 2 is attached to the first attachment point 1a, as shown in Figures 3 and 7, the shelf plate 3 can be detachably attached to the third attachment point 1c by screwing the bolts (not shown) through the screw insertion notches 33a into the nuts n4 of the lower connecting plate 14.

Furthermore, in this embodiment, a fascia board 4 is provided hanging down from the opposite end of the top plate 2, and the top plate 2 can be moved together with the wiring duct 6 and fascia board 4 described below to be attached to either the first attachment point 1a or the second attachment point 1b described above.

In more detail, as shown in Figures 1 to 3 and 7 to 11, the fascia 4 is made of sheet metal and has a flat fascia body 41, an upper plate 42 extending forward from the upper edge of the fascia body 41, side plates 43 extending forward from both the left and right edges of the fascia body 41, and a lower frame 44 extending forward from the lower edge of the fascia body 41. The fascia 4 is removably screwed to the leg body 1 in a position where the upper plate 42 can support the underside of the wiring duct 6 attached to the top plate 2, by screwing a bolt (not shown) through the screw insertion hole 43x of the side plate 43 into the fascia attachment nut n5 of the rear leg column 12. In addition, a notch 43a is provided in the lower part of the side plate 43.

A sub-shelf 5 different from the shelf 3 described above is arranged at the lower end of the apron 4. As shown in Figures 1 to 3 and 7 to 11, this sub-shelf 5 is made of sheet metal and has both front and rear edges and both left and right edges extending downward, and shelf support brackets 52 provided on both the left and right sides of this sub-shelf body 51. A front frame 511 extending downward is provided at the front edge of the sub-shelf body 51, a rear frame 512 extending downward is provided at the rear edge of the sub-shelf body 51, and side plates 513 extending downward are provided at both left and right edges of the sub-shelf body 51. The shelf support bracket 52 is provided with a bracket body 521 that is attached to the inner surface of the rear leg column 12, and a receiving plate 522 that extends inward from the bracket body 521 and supports the widthwise ends of the front frame 511 and rear frame 512 of the sub-shelf body 51. The sub-shelf body 51 is fixed to the shelf support bracket 52 by screwing a bolt (not shown) that has passed through the screw insertion hole 522a of the receiving plate 522 into a nut n6 provided in the front frame 511 and rear frame 512 of the sub-shelf body 51, and the rear part of the bracket body 521 is placed in the notch 43a of the side plate 43, and the sub-shelf 5 is removably attached to the leg body 1 by screwing a bolt (not shown) that has passed through the screw insertion hole 521a of the bracket body 521 into a nut n7 for attaching the sub-shelf to the rear leg column 12.

Here, the sub-shelf 5 is located above the third mounting point 1c regardless of whether the top plate 2 is attached to the first or second mounting point 1a, 1b. In particular, when the top plate 2 is attached to the first mounting point 1a and the shelf plate 3 is attached to the third mounting point 1c, the shelf plate 3 is located below the sub-shelf 5.

In this desk D, a wiring duct 6, as described below, is provided on the opposite end 2b of the top plate 2, i.e., above the back panel 4 and behind the top plate 2.

As shown in Figures 4 to 6, 13 and 14, the wiring duct 6 comprises a bottom wall 61, a tip wall 62 extending from the tip of the bottom wall 61 in a direction substantially perpendicular to the bottom wall 61, and an attachment portion 63 provided on the base end side of the bottom wall 61 for detachably attaching the bottom wall 61 to the underside of the top plate 2. The attachment portion 63 comprises a first attachment portion 64 for attaching the bottom wall 61 to the top plate 2 in a position in which the tip wall 62 stands upward (hereinafter referred to as the first attachment position (P)), and a second attachment portion 65 for attaching the bottom wall 61 to the top plate 2 in a position in which the tip wall 62 hangs downward (hereinafter referred to as the second attachment position (Q)). Either the first attachment portion 64 or the second attachment portion 65 can be selectively attached to the common attachment portion 23 of the top plate 2. Here, Figs. 1 to 11 show the wiring duct 6 attached to the top plate 2 in the first mounting position (P). Figs. 12 to 18 show the wiring duct 6 attached to the top plate 2 in the second mounting position (Q). Wiring can be led from devices (not shown) placed on the upper surface 2a of the top plate 2 to the wiring insertion space 6s formed above the bottom wall 61. In this embodiment, the first mounting portion 64 and the second mounting portion 65 are provided at different positions in the front-to-rear direction.

In more detail, as shown in Figures 5, 6 and 14, the left and right ends of the front part of the bottom wall 61 are provided with cutouts 61a for inserting wiring, so that wiring that has risen from the floor can be led onto the bottom wall 61. In addition, the left and right ends of the rear part of the bottom wall 61 are provided with engagement parts 61b for engaging with the top plate support bracket 22. That is, the rear end of the top plate support bracket 22 is provided with an engagement recess 22b in the shape of a substantially horizontal slit that is open to the rear, so that the engagement part 61b of the wiring duct 6 described above can be slid into engagement recess 22b from the rear.

4 and 13, the first mounting portion 64 is integrally provided with a horizontal plate 641, a front vertical plate 642 extending from the front edge of the horizontal plate 641, and a rear vertical plate 643 extending from the rear edge of the horizontal plate 641. The horizontal plate 641 is provided with a screw insertion hole 641a. The second mounting portion 65 is integrally provided with a horizontal plate 651, a front vertical plate 652 extending from the front edge of the horizontal plate 651, and a rear vertical plate 653 extending from the rear edge of the horizontal plate 651. The horizontal plate 651 is provided with a screw insertion hole 651a. The rear vertical plate 653 of the second mounting portion 65 is integrally formed continuously with the front vertical plate 642 of the first mounting portion 64 from the same sheet metal material. Either the horizontal plate 641, 651 of the first mounting portion 64 or the second mounting portion 65 is selectively fastened to the common mounting portion 23 of the top plate 2. More specifically, the wiring duct 6 is fastened to the top plate 2 by screwing a screw 66 inserted through either of the screw insertion holes 641a, 651a into an embedded nut 231 embedded in the common mounting portion 23. That is, the common mounting portion 23 in this embodiment is a linear portion set parallel to the opposite end 2b of the lower surface 21c of the top plate 2, and a plurality of embedded nuts 231 are provided intermittently at intervals in the left-right direction. The distance d3 between the common mounting portion 23 and the opposite end 2b of the top plate 2 is set so that an overhang portion 2X is formed in the vicinity of the opposite end 2b of the top plate 2, where a space is formed between the underside 21c of the top plate 2 and the wiring duct 6, regardless of whether the wiring duct 6 is mounted in the first mounting position (P) or the second mounting position (Q). The overhang portion 2X has a different rearward extension dimension when the wiring duct 6 is mounted in the first mounting position (P) or the second mounting position (Q). In either case, however, the overhang portion 2X is designed to be able to be fitted with a clamp or the like (not shown) for optional mounting. In this embodiment, the vertical distance d1 between the bottom wall 61 and the first mounting portion 64 is set equal to the vertical distance d2 between the bottom wall 61 and the second mounting portion 65.

When this wiring duct 6 is attached to the top plate 2 in the first attachment position (P), i.e., when the first attachment portion 64 is attached to the top plate 2, the outer surface 62a of the tip wall 62 is approximately flush with the rear end surface of the leg 1 supporting the top plate 2 (rear end surface 12y of the rear leg column 12), as shown in Figures 2 to 4, 9 and 10.

On the other hand, when the wiring duct 6 is attached to the tabletop 2 in the second attachment position (Q), i.e., when the second attachment portion 65 is attached to the tabletop 2, the outer surface 62a of the tip wall 62 protrudes outward from the rear end surface of the leg 1 (rear end surface 12y of the rear leg column 12) as shown in Figures 12, 13 and 17. In this case, as shown in Figures 15, 16 and 18, by arranging another desk D2 having the same configuration facing each other and butting the outer surfaces 62a of the tip walls 62 against each other, a wiring insertion space 6s is formed that spans above the bottom walls 61 of the wiring ducts 6 of both desks D1, D2 and is accessible from above. 12, 13, 15, and 16 show the tabletop 2 attached to the first attachment point 1a of the leg 1 (held in the high-level position (H)), and 17 and 18 show the tabletop 2 attached to the second attachment point 1b of the leg 1 (held in the low-level position (L)).

Here, FIG. 1 is an overall perspective view showing a state in which the top plate 2 is attached to the first attachment point 1a of the leg body 1 (the top plate 2 is held in a high level position (H)) and the wiring duct 6 is attached to the top plate 2 in a first attachment position (P) (the outer surface 62a of the tip wall 62 is flush with the rear end surface of the leg body 1). FIG. 2 is an overall rear perspective view of the same. FIG. 3 is a side cross-sectional view of the same. FIG. 4 is an enlarged view of the main parts in FIG. 3. FIG. 5 is an oblique view showing the wiring duct 6 and the top plate support bracket 22 in the state of FIG. 1. FIG. 6 is a plan view showing the wiring duct 6 and the top plate support bracket 22 in the same state. FIG. 7 is an exploded perspective view showing a manner in which the top plate 2 is attached to the first attachment point 1a of the leg body 1. FIG. 8 is an overall perspective view showing a state in which the top plate 2 is attached to the second attachment portion 1b of the leg body 1 (the top plate 2 is held in the low level position (L)) and the wiring duct 6 is attached to the top plate 2 in the first attachment position (P) (the outer surface 62a of the tip wall 62 is flush with the rear end surface of the leg body 1). FIG. 9 is an overall rear perspective view of the same. FIG. 10 is a side cross-sectional view of the same. FIG. 11 is an exploded perspective view showing a manner in which the top plate 2 is attached to the second attachment portion 1b of the leg body 1. FIG. 12 is an overall perspective view showing a state in which the top plate 2 is attached to the first attachment portion 1a of the leg body 1 (the top plate 2 is held in the high level position (H)) and the wiring duct 6 is attached to the top plate 2 in the second attachment position (Q) (the outer surface 62a of the tip wall 62 protrudes outward from the rear end surface of the leg body 1). FIG. 13 is a side cross-sectional view of the same. FIG. 14 is a perspective view showing the wiring duct 6 and the top plate support bracket 22 in the state of FIG. 12. FIG. 15 is an overall perspective view showing the state in which the desks D1 and D2 in the state of FIG. 12 are arranged facing each other. FIG. 16 is an enlarged cross-sectional view of the main part in the state of FIG. 15. FIG. 17 is an overall perspective view showing the state in which the top plate 2 is attached to the second attachment point 1b of the leg body 1 (the top plate 2 is held in the low level position (L)) and the wiring duct 6 is attached to the top plate 2 in the second attachment position (Q) (the outer surface 62a of the tip wall 62 protrudes outward from the rear end surface of the leg body 1). FIG. 18 is an overall perspective view showing the state in which the desks D1 and D2 in the state of FIG. 17 are arranged facing each other. The cut portions of FIG. 3 and FIG. 10 are planes corresponding to the widthwise position corresponding to the axis of the screw insertion holes 641a and 651a on the left side of the widthwise center of the wiring duct 6.

With this configuration, the first mounting portion 64 or the second mounting portion 65 of the wiring duct 6 can be selectively attached to the common mounting portion 23 set at a specific location on the top plate 2, making it possible to guide the wiring in different ways while eliminating the need for complicated mounting locations.

In addition, since the first mounting part 64 and the second mounting part 65 are provided at different positions in the front-to-rear direction, the relative position of the wiring duct 6 with respect to the top plate 2 in the front-to-rear direction can be changed by attaching either the first mounting part 64 or the second mounting part 65 to the common mounting portion 23.

In addition, the vertical separation distance d1 between the bottom wall 61 and the first mounting portion 64 in the wiring duct 6 is set equal to the vertical separation distance d2 between the bottom wall 61 and the second mounting portion 65, so that the relative height position of the bottom wall 62 with respect to the top plate 2 does not change regardless of whether the mounting position is the first or second mounting position (P) or (Q).

The top plate support bracket 22 is provided with engagement recesses 22b that engage with the engagement portions 61b at both ends of the bottom wall 61 of the wiring duct 6, so that the top plate support bracket 22 and the wiring duct 6 can be positioned by engaging these engagement portions 61b with the engagement recesses 22b. In particular, in this embodiment, regardless of whether the mounting position is the first or second mounting position (P) or (Q), the engagement portion 61b of the wiring duct can be engaged with one type of engagement recess 22b, so that the complexity of the structure can be suppressed.

The first mounting part 64 and the second mounting part 65 are channel-shaped and each of them is integrally provided with a horizontal plate 641, 651, a front vertical plate 642, 652 extending from the front edge of the horizontal plate 641, 651, and a rear vertical plate 643, 653 extending from the rear edge of the horizontal plate 641, 651. Either the horizontal plate 641 of the first mounting part 64 or the horizontal plate 651 of the second mounting part 65 is selectively fastened to the common mounting part 23 of the top plate 2. This allows the first and second mounting parts 64, 65 of the wiring duct 6 to act as reinforcing members that suppress warping of the top plate 2.

The wiring duct 6 is configured so that in the first mounting position (P), the outer surface 62a of the tip wall 62 is substantially flush with the rear end surface 12y of the rear leg column 12, and in the second mounting position (Q), the outer surface 62a of the tip wall 62 protrudes outward beyond the rear end surface 12y of the rear leg column 12. This allows a wide wiring insertion space 6s when the wiring duct 6 is mounted on the tabletop 2 in the second mounting position (Q) and the two desks D1, D2 are arranged facing each other. In addition, because a gap can be formed between the legs 1 of the two desks D1, D2 when they are arranged facing each other, this gap can also be used as an installation space for a partition panel or the like, as in the second and third embodiments described below.

In addition, by attaching the tabletop 2 to the first attachment position 1a on the left and right legs 1, the upper surface 2a of the tabletop 2 is held in a high-level position (H), allowing the user to face the tabletop 2 in a standing position. If a high-type chair with a seating surface higher than chairs normally used in offices is separately prepared and used together with the desk D with the upper surface 2a of the tabletop 2 held in the high-level position (H), the desk D can also be used in a seated position.

On the other hand, by attaching the tabletop 2 to the second attachment position 1b on the left and right legs 1, the upper surface 2a of the tabletop 2 is held in a low level position (L), which is suitable for the user to face the tabletop 2 in a seated position.

Second Embodiment (FIGS. 19 to 26)
Hereinafter, another embodiment (embodiment 2) of the present invention will be described with reference to FIGS.

As shown in Figures 19, 20, and 22 to 26, the desk DD of the second embodiment has a first partition panel 71 that functions as a desktop panel near the opposite end 2b of the top plate 2, and a second partition panel 72 that functions as a side panel near one side end 2c of the top plate 2.
