Description

The present invention relates to a desk whose tabletop height can be changed.

A conventional desk of this type is one in which a connecting member is installed between a pair of legs and the top is fixed to the front of the connecting member (see, for example, Patent Document 1).

This fixture is designed so that the height of the tabletop can be changed by changing the attachment position of the connecting member relative to the legs. However, it is not envisaged that multiple such fixtures will be placed next to each other for use.

As a result, even if such fixtures are placed facing each other with the same tabletop height, the connecting members will exist as obstacles between the tabletops of one fixture and the other, preventing one of the benefits of placing fixtures facing each other from being achieved, namely, that the upper surfaces of the tabletops placed facing each other can be used as a continuous, flush surface.

Furthermore, no consideration is given to the height relationship between the tabletop and the shelves of other fixtures, making the space look cluttered when multiple fixtures are placed next to each other.

JP 2019-201740 A

The present invention aims to solve all of the above problems at the same time.

The desk of the invention described in claim 1 comprises legs having a first mounting point and a second mounting point which are at different heights, a tabletop which can be selectively attached to either the first or second mounting point, and a shelf which is attached to the first mounting point with the tabletop attached to the second mounting point, and is configured so that the upper surface of the tabletop or shelf can be flush and continuous with the upper surface of the tabletop or shelf of another desk of the same structure which is arranged adjacently or facing each other.

Here, "the upper surface of the tabletop or shelf can be flush and continuous with the upper surface of the tabletop or shelf of another desk of the same structure that is arranged adjacently or facing each other" is a concept indicating that there are no obstacles between the upper surface of the tabletop or shelf and the upper surface of the tabletop or shelf of the other desk, and items can be placed across them.

The desk according to the invention described in claim 2 is the desk described in claim 1, in which the tabletop attached to the first attachment point is held in a high level position suitable for use by a user in a standing position.

The desk according to the invention described in claim 3 is the desk described in claim 1, in which the tabletop attached to the second attachment point is held in a low-level position suitable for use by a user in a seated position.

The desk according to the invention described in claim 4 is the desk described in claim 1, 2 or 3, and has a valance hanging down from the opposite end of the tabletop, and is configured so that the tabletop can be moved together with the valance to be attached to either the first attachment point or the second attachment point.

The desk according to the invention described in claim 5 is the desk described in claim 4, and the legs are configured so that the rear end faces are raised substantially vertically, and the rear end of the tabletop when the relationship between the tabletop and the skirting board is such that the tabletop wins, or the rear end of the skirting board when the relationship between the tabletop and the skirting board is such that the rear end faces of the legs are substantially flush with each other.

The desk according to the invention described in claim 6 is the desk described in claim 4 or 5, in which a sub-shelf board different from the shelf board is arranged at the lower end of the back panel.

The invention of claim 7 relates to a desk according to claim 6, and the legs are provided with a third attachment point for attaching the shelf board to a position lower than the sub-shelf board when the top board is attached to the first attachment point.

This invention not only allows the height position of the tabletop to be changed to diversify the positions in which it can be used, but also allows the top surfaces of the tabletops or the top surfaces of the tabletop and shelf to be flush and continuous when placed next to other desks of the same structure. This makes it possible to use the top surfaces widely and effectively, while also providing a neat appearance.

One embodiment of the present invention (embodiment 1) will be described below with reference to Figures 1 to 11.

As shown in Figs. 1 to 6, 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 tabletop 2 that can be selectively attached to either the first or second mounting point 1a or 1b, and a shelf 3 that is attached to the first mounting point 1a while the tabletop 2 is attached to the second mounting point 1b. The top surface 2a of the tabletop 2 is configured to be flush and continuous with the top surface 2a, 3a of the tabletop 2 or shelf 3 of the adjacent desk D2 of the same structure.

In more detail, as shown in Figs. 1 to 6, 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 a screw hole opening on the inner 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 top plate. Specifically, each nut n2 is embedded in the front and rear legs 11, 12 with a screw hole opening on the inner side of the leg body 1, like the four 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 top plate 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 top plate 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 6, the tabletop 2 comprises a rectangular wooden tabletop body 21 and brackets 22 attached to both the left and right ends of the underside 21c of the tabletop body 21. The bracket 22 comprises a bracket body 221 arranged on the side of the tabletop body 21 and an attachment portion 222 extending from the lower edge of the bracket body 221 and 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. The tabletop 2 can be detachably attached to either the first or second attachment point 1a or 1b 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 top plate 2 attached to the first mounting location 1a is held in a high level position (H) as shown in Figures 1 to 3, which is suitable for use by a user in a standing position, and the top plate 2 attached to the second mounting location 1b is held in a low level position (L) as shown in Figures 4 to 6, which is suitable for use by a user in a seated position. In this embodiment, the upper surface 2a of the top plate 2 held in the high level position (H) is held at a height position 900 mm away from the floor surface, and the upper surface 2a of the top plate 2 held in the low level position (L) is held at a height position 720 mm away from the floor surface. These numerical values are examples, and the design can be changed as appropriate. When the top plate 2 is attached to the first mounting location 1a, the shelf plate 3 is attached to the third mounting location 1c as shown in Figures 1 to 3, and when the top plate 2 is attached to the second mounting location 1b, the shelf plate 3 is attached to the first mounting location 1a as shown in Figures 4 to 6. The shelf board 3 attached to the third attachment point 1c can function not only as a shelf board, 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 board 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 2, 3, 5, and 6, 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 5 and 6, 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 2 and 3, 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 fascia board 4 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 2, 3, 5 and 6, 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 side edges of the fascia body 41, and a lower frame 44 extending forward from the lower edge of the fascia body 41. The upper plate 42 is screwed to the rear end of the lower surface of the top plate 2 (more precisely, the lower surface 21c of the top plate body 21), and the fascia 4 is detachably screwed to the leg body 1 by passing a bolt (not shown) through a screw insertion hole 43x of the side plate 43 and screwing it into the fascia mounting nut n5 of the rear leg column 12. In addition, a notch 43a is provided at the lower part of the side plate 43.

A sub-shelf board 5 different from the shelf board 3 described above is arranged at the lower end of the fascia board 4. As shown in Figures 2, 3, 5 and 6, this sub-shelf board 5 is provided with a sheet metal sub-shelf board body 51 with both front and rear edges and both left and right edges extending downward, and brackets 52 provided on both the left and right sides of this sub-shelf board body 51. A front frame 511 extending downward is provided at the front edge of the sub-shelf board body 51, a rear frame 512 extending downward is provided at the rear edge of the sub-shelf board body 51, and side plates 513 extending downward are provided at both left and right edges of the sub-shelf board body 51. The 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 the rear frame 512 of the sub-shelf board body 51. The sub-shelf body 51 is fixed to the 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, the relationship between the top board 2 and the back panel 4 is such that the top board wins, and the rear end 2b of the top board 2 is approximately flush with the rear end surface 12y of the leg body 1. Furthermore, in this embodiment, the rear end 4a of the back panel 4 is also approximately flush with the rear end surface 12y of the leg body 1. When this desk D1 is placed opposite another desk D2 having the same structure, the rear ends (surfaces) 12y, 2b, and 4a of the leg body 1, top board 2, and back panel 4 of this desk D1 can be brought into close contact with the rear ends (surfaces) 12y, 2b, and 4a of the leg body 1, top board 2, and back panel 4 of the other desk D2 having the same structure.

Here, FIG. 1 is an overall perspective view showing the tabletop 2 attached to the first attachment point 1a of the leg body 1. FIG. 2 is a central side cross-sectional view of the same. FIG. 3 is an exploded perspective view showing the manner in which the tabletop 2 is attached to the first attachment point 1a of the leg body 1. FIG. 4 is an overall perspective view showing the tabletop 2 attached to the second attachment point 1b of the leg body 1. FIG. 5 is a central side cross-sectional view of the same. FIG. 6 is an exploded perspective view showing the manner in which the tabletop 2 is attached to the second attachment point 1b of the leg body 1.

With such a configuration, by attaching the top plate 2 to the first attachment position 1a on the left and right leg bodies 1, the upper surface 2a of the top plate 2 is held in a high level position (H), and the user can face the top plate 2 in an upright position. In this case, the shelf board 3 can be attached to the third attachment position 1c on the leg body 1. Therefore, this shelf board 3 is located below the sub-shelf board 5 that is located at the lower end of the fascia board 4 and attached to the leg body 1, and both the shelf board 3 and the sub-shelf board 5 can be used by placing files and other stored items on them. In this case, the back of the space formed between the sub-shelf board 5 and the top plate 2 is hidden by the fascia board 4, so that the stored items placed on the sub-shelf board 5 can be prevented from being seen by others from behind. Furthermore, if a high-type chair with a seating surface higher than chairs normally used in offices is prepared separately and used with desk D with the top surface 2a of the tabletop 2 held at a high level position (H), the desk D can be used in a seated position, making it easy for the occupant to stand up and sit down, making it suitable for communication between the seated and standing person, and allowing two levels of A4-sized files to be stored under the feet.

When multiple desks D1, D2 are arranged side-by-side (see FIG. 7) or facing each other (see FIG. 9) in such a position, the upper surfaces 2a of the tabletops 2 of both desks D1, D2 will be flush and continuous. In other words, in such an installation mode, the upper surface 2a of the tabletop 2 of a specific desk D1 will be flush and continuous with the upper surface 2a of the tabletop 2 of another desk D2 that has the same structure as that desk D1.

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 at a low level position (L), which is suitable for the user to face the tabletop 2 in a seated position. In this case, the shelf 3 can be removed from the third attachment point 1c and attached to the first attachment point 1a. In this case, the upper surface 3a of the shelf 3 is held at a high level position (H) higher than the upper surface 2a of the tabletop 2 held at the low level position (L). The fascia 4 can be moved together with the tabletop 2 and attached to the legs 1 in a hanging position from the tabletop 2 at the low level position (L). The sub-shelf 5 can also be moved downward in the same way and attached to a new position, and the relative positions of the sub-shelf 5 and the tabletop 2 in this attached state are configured to be the same. Therefore, a certain space is always formed above the sub-shelf 5, and the back of this space is hidden by the fascia 4. Therefore, even when the top plate 2 is held in the low-level position (L), items placed on the sub-shelf plate 5 can be prevented from being seen by others from behind.

When multiple desks D1, D2 are arranged side-by-side (see FIG. 8) or facing each other (see FIG. 10) in such a position, the upper surfaces 2a, 3a of the tabletops 2 or shelves 3 of both desks D1, D2 will be flush and continuous. In other words, in such an installation mode, the upper surfaces 2a, 3a of the tabletops 2 or shelves 3 of a specific desk D1 will be flush and continuous with the upper surfaces 2a, 3a of the tabletops 2 or shelves 3 of another desk D2 that has the same structure as that desk D1.

7 and 9 show an example in which desks D with tabletops 2 held in a high level position (H) are arranged adjacent to each other, and Figs. 8 and 10 show an example in which desks D with tabletops 2 held in a low level position (L) are arranged adjacent to each other, but for example, as shown in Fig. 11, desks D1 and D2 with tabletops 2 held in a high level position (H) and desks D3 and D4 with tabletops 2 held in a low level position (L) can be arranged adjacent to each other. Even in this case, the upper surface 2a of the tabletops 2 of desks D1 and D2 with tabletops 2 held in a high level position (H) and the upper surface 3a of the shelf board 3 of desks D3 and D4 with tabletops 2 held in a low level position (L) will be flush and continuous.

When multiple desks D1, D2 are arranged side-by-side, as shown in Figures 7, 8, and 11, the upper connecting members 13 of the desks D1, D2 come into contact with each other, and the notches 13a of the upper connecting members 13 face each other and communicate with each other, functioning as wiring insertion holes downward.

In this way, the upper surface 2a of the tabletop 2 of this desk D can be flush and continuous with the upper surfaces 2a, 3a of the tabletop 2 or shelf 3 of another adjacent desk D of the same structure. This not only allows the height position of the tabletop 2 to be changed to diversify the positions of use, but also allows the upper surfaces 2a of the tabletop 2, the upper surfaces 3a of the shelf 3, or the upper surfaces 2a, 3a of the tabletop 2 and shelf 3 to be flush and continuous when placed adjacent to or facing another desk D of the same structure. This makes it possible to use the upper surfaces 2a, 3a widely and effectively, while also providing a neat appearance.

The tabletop 2 attached to the first and second attachment points 1a and 1b is designed to be held at a high level position (H) and a low level position (L), respectively. By changing the attachment point of the tabletop 1 as needed, it can be used as a so-called high desk used by the user in a standing position, or as a normal desk used by the user in a seated position.

And because the legs 1 are provided with a third mounting point 1c for mounting the shelf 3 at a lower position than the sub-shelf 5 when the top plate 2 is attached to the first mounting point 1a, there is no need to secure a separate storage location for the shelf 3 removed from the first mounting point 1a when changing the mounting point of the top plate 2 from the second mounting point 1b to the first mounting point 1a, and furthermore, as mentioned above, the shelf 3 can also function as a footrest.

Note that the present invention is not limited to the embodiments described above.

The desk D of the embodiment 1 described above has a structure in which the top board is dominant, but the present invention is of course not necessarily limited to this, and may be, for example, a desk with a top board dominant such as desk DD (embodiment 2) shown in Figures 12 to 14, desk DDD (embodiment 3) shown in Figures 15 to 18, or desk D4 (embodiment 4) shown in Figures 19 to 21.

FIG. 14 is a cross-sectional view taken along line X-X in FIG. 12.

The desk DDD of the third embodiment has a structure in which the back panel is the same as the desk DD of the second embodiment, but unlike the second embodiment, the top end 4x of the back panel 4 forms a wiring duct H. More specifically, as shown in Figures 15 to 18, the back panel 4 of the desk DDD is made of sheet metal and integrally includes a flat back panel body 41, a duct horizontal panel 47 extending forward from the upper edge of the back panel body 41, a duct standing panel 48 erected from the extending end of the duct horizontal panel 47, a mounting panel 49 extending forward from the upper edge of the duct standing panel 48 and fastened to the rear end vicinity of the lower surface 21c of the tabletop body 21, side panels 43 extending forward from both the left and right side edges of the back panel body 41, and a lower frame 44 extending forward from the lower edge of the back panel body 41. The duct horizontal panel 47 and the duct standing panel 48 form a wiring duct H that is open upward and backward. In addition, a guard member 6 for guiding the wiring on the wiring duct H is provided at the middle part of the duct horizontal plate 47. The guard member 6 is integrally provided with a rear plate 61 rising from the upper edge of the front panel main body 41, an upper plate 62 extending forward from the upper edge of the rear plate 61, and a mounting plate 63 hanging down from the extended end of the upper plate 62, and the mounting plate 63 is fixed to the rear end 21b of the top panel main body 21. Here, the rear surface 61a of the rear plate 61 is flush with the rear end 4a of the front panel 4. In addition, the upper surface 62a of the upper plate 62 is flush with the upper surface 2a of the top panel 2. The left and right ends of the duct horizontal plate 47 are provided with a notch 47a for inserting the wiring. Note that the configuration other than that described above is similar to that of the first embodiment, and the same reference numerals are used for the same or corresponding parts as those of the first embodiment, and the description thereof will be omitted.
