Description

The present invention relates to furniture with a tabletop that is suitable for installation in conference rooms, etc.

For companies, there are many types of communication that cannot afford to fail, such as important contracts and negotiations, job interviews, and exchanges between management-related boards. To make such communication successful, not only verbal information but also the whole picture, including facial expressions and gestures, is important, and fostering an implicit atmosphere in the room is important for reaching an agreement. Such communication often takes place in conference rooms, etc., and tables that are installed and used in such conference rooms and the like are known to have a tabletop and legs that support at least both ends of the tabletop (see, for example, Patent Document 1).

Nowadays, due to the COVID-19 pandemic, infection prevention has become a priority, and the use of conference rooms has been restricted to avoid crowding in enclosed spaces. As a result, people are forced to communicate in open environments with no confidentiality, or through transparent barriers such as acrylic panels, vinyl sheets, or glass panels.

However, for business purposes, there is a demand for conference rooms to be a place for safe, intimate communication.

The first vertical frame member 71 extends from near one end edge 1a of the tabletop 1 to near the other end edge 1b. The second vertical frame member 72 extends from near one end edge 1a of the tabletop 1 to near the center of the tabletop 1 in the width direction. The end horizontal frame member 73 supports the lower surfaces of the end plate members 61 and 63 of the tabletop body 6. The first intermediate horizontal frame member 74 connects the longitudinal centers of the first vertical frame members 71 and further extends toward the use ends 1c and 1d, connecting one end of the second vertical frame member 72 near the end. The second intermediate horizontal frame member 75 supports from below the boundary between the end plate member 61 and the intermediate plate member 62 on one end 1a of the tabletop 1 (tabletop body 6), the boundary between the intermediate plate members 62, and the boundary between the intermediate plate member 62 and the end plate member 63 on the other end 1b. The one end edge 1a of this tabletop support frame 7 is supported from below by the side unit 2.

The side unit 2 functions as a leg that supports one edge 1a of the tabletop 1, and as shown in Figures 1, 2, 9, and 10, has a side unit body 21 that has a space that opens outward and can store equipment inside, and a door 22 provided at the open end of this space. The side unit body 21 defines a space capable of storing the aforementioned equipment by a top wall 23, a back wall 24, both side walls 25, and a bottom wall 26.

On the other hand, as mentioned above, the other end edge 1b side of the tabletop 1 is supported by the end leg 31. As shown in Figures 2, 3, 5, 9 and 10, the end leg 31 is a plate-like member provided to support the other end of the tabletop support frame 7, in other words the end horizontal frame member 73 on the other end side, from below. An intermediate leg 32 is disposed between the side unit 2 and the end leg 31.

As shown in Figures 2, 3, 5, 9 and 10, the intermediate leg 32 is a plate-like member that is provided to support the center of the tabletop support frame 7, in other words, the central intermediate horizontal frame member 74, from below.

Furthermore, in this embodiment, as shown in Figs. 2, 5, 9 and 10, panel-shaped first auxiliary legs 33 are provided on the inner surfaces of the side unit 2 and the end leg 31, and on both sides of the intermediate leg 32. In addition, panel-shaped second auxiliary legs 34 are provided between the side unit 2 and the intermediate leg 4, and between the end leg 3 and the intermediate leg 4. A leg base 35 is attached to the lower ends of these auxiliary legs 33, 34. The upper end of the first auxiliary leg 33 reaches the lower surface of the top plate 1. The second holding leg 34 is fixed to the dust collection unit cover 51, which will be described later, by a bracket 341.

As shown in Figures 2, 5, 8, 9 and 10, a pair of dust collection unit support frames 8 are installed between the lower parts of the adjacent auxiliary legs 33, 34. The undersides of both ends of the dust collection unit support frame 8 are in surface contact with the leg base 35, and both ends are fixed to the auxiliary legs 33, 34 via brackets 81. A dust collection unit receiver 82 is installed between the pair of dust collection unit support frames 8, and the dust collection unit 4 is placed on the dust collection unit receiver 82. In other words, the dust collection unit 4 is supported in a state separated from the floor surface F by the dust collection unit support frame 8 and the dust collection unit receiver 82.

In this embodiment, a storage section S for storing the dust collection unit 4 is provided below the top plate 1. This storage section S is constructed using the above-mentioned top plate support frame 7, the legs 31 and 32 that support this top plate support frame 7, and the above-mentioned dust collection unit support frame 8.

As shown in Figures 2, 5, 6, 7, 9 and 1, the dust collection unit 4 is a well-known unit having an air intake 4a on the upper surface and an exhaust port 4b on the lower surface. Here, the width of the air intake 4a of the dust collection unit 4 is smaller than the width of the opening 1x of the top plate 1. In other words, the width of the opening 1x of the top plate 1 is set to a value larger than the width of the air intake 4a of the dust collection unit 4. The air above the top plate 1 and the floating matter in the air are guided to this dust collection unit 4 via the air introduction passage 5.

The air introduction passage 5 is formed between the top plate 1 and the dust collection unit 4, and as described above, connects to the outside only through the opening 1x of the top plate 1. As shown in Figures 6 and 7, the front and rear ends of this air introduction passage 5 are defined by the dust collection unit cover 51, and both left and right ends are defined by the first auxiliary legs 33. The lower end is defined by the dust collection unit 4 and the lid body 52, which is a horizontal plate-like member that closes the space between the dust collection units 4.

As shown in FIG. 7, the dust collection unit cover 51 includes a cover body 511 that connects the upper ends of adjacent first auxiliary legs 33, a sound insulation cushion 512 that is a first spacer that contacts the upper surface of the cover body 511 and fills the space between the top plate 1, and a cushion sheet 513 that is a second spacer that contacts the inner surface of the cover body 511 and fills the space between the dust collection unit 4. Both ends of the cover body 511 are fixed to the first auxiliary legs 33 via brackets 514.

As shown in Figures 7 and 9, the lid body 52 connects the upper surfaces of two adjacent dust collection units 4 and between the dust collection unit 4 and the auxiliary leg body 33, and forms the lower surface of the air introduction passage 5. The lid body 52 is fixed to the auxiliary legs 33 and 34 by brackets 53.

Furthermore, in this embodiment, as shown in Figures 1, 3, 4, 6 and 7, a partition plate 91 is arranged to stand up from the opening edge of the opening 1x of the top plate 1 and surround the opening 1x, and air is guided to the air introduction passage 5 through the upper air introduction passage 9 that is separated by this partition plate 91 and opens upward.

7, its outer surface is attached to the opening edge of the opening 1x in the tabletop, and its lower end reaches downward beyond the underside of the tabletop 1, and its lower end is sandwiched between the tabletop mounting bracket 92 and the auxiliary mounting plate 93. The tabletop mounting bracket 92 includes a horizontal plate-like mounting portion 921 fixed to the underside of the tabletop 1, a plate-like hanging portion 922 that hangs down from one end edge of the mounting portion 921 and attaches to the outer surface of the tabletop 11, and a horizontal plate-like support portion 923 that extends inward from the hanging end of the hanging portion 922 and supports the tabletop 91 from below. This support portion 923 also supports the auxiliary mounting plate 93 from below, and the outer surface of the auxiliary mounting plate 93 is attached to the inner surface of the partition plate 91. The partition plate 91 and the auxiliary mounting plate 93 are fastened together with screws (not shown), so that the partition plate 91 is attached to the top plate 1.

On the other hand, a horizontal partition plate 50 is placed above the auxiliary mounting plate 92, separating the upper air inlet passage 9 from the air inlet passage 5. As shown in FIG. 7, this horizontal partition plate 50 is equipped with a horizontal partition plate body 501 having a plurality of air flow openings (not shown) formed by punching to allow air to flow between the upper air inlet passage 9 and the air inlet passage 5, and a hanging part 502 that hangs down from the periphery of the horizontal partition plate body 501 and whose lower end abuts against the auxiliary mounting plate 93.

In addition, in this embodiment, a fascia 10 that conceals the dust collection unit 4 from the outside space is disposed below the top plate 1. As shown in Figs. 3 and 6, a lower exhaust port 10a is provided at the lower edge of this fascia 10, through which exhaust air from the dust collection unit 4 passes, and an upper exhaust port 10b is provided at the upper edge of this fascia 10, through which exhaust air from the dust collection unit 4 passes.

As shown in FIG. 6, the fascia 10 includes a fascia body 101 that closes the front or rear ends of the adjacent auxiliary legs 33, 34, and a mounting bracket 102 that is provided at both left and right ends of the back surface of the fascia body 101 and has engagement recesses 103 that engage with fascia locking pins 104 provided on the auxiliary legs 33, 34. The fascia 10 is attached to the auxiliary legs 33, 34 by engaging the engagement recesses 103 of the mounting bracket 102 with the fascia locking pins 104. A space is formed between the lower edge of the fascia 10 and the floor surface F, and this space is the lower exhaust port 10a. A space is also formed between the upper edge of the fascia 10 and the top plate 1, and this space is the upper exhaust port 10b.

The following describes the air flow around table T when dust collection unit 4 is operating.

The air above the top plate 1 of the table T, as well as floating objects contained in the air, are taken into the dust collection unit 4 through the upper air inlet passage 9 and the air inlet passage 5 and the dust collection unit 4 through the intake port 4a of the dust collection unit 4. The floating objects contained in the air taken into the dust collection unit 4 are separated from the air by a filter or the like in the dust collection unit 4 and are stored in the dust collection unit 4 or are removed by electrolysis or the like. Meanwhile, the air taken into the dust collection unit 4 is exhausted downward from the exhaust port 4b of the dust collection unit 4. The air exhausted from the dust collection unit 4 is guided through the lower exhaust port 10a at the lower edge of the skirting board 10 and the upper exhaust port 10b at the upper edge of the skirting board 10 to the outside of the skirting board 10, i.e., the side where the seated person is seated.

Here, FIG. 1 is a top perspective view of table T of this embodiment, and FIG. 2 is a bottom perspective view of table T. FIG. 3 is a front view of table T, FIG. 4 is a plan view of table T, and FIG. 5 is a bottom view of table T. FIG. 6 is a cross-sectional view taken along line X-X in FIG. 3. FIG. 7 is an enlarged view of portion Y in FIG. 6, and FIG. 8 is an enlarged view of portion Z in FIG. 6. FIG. 9 is a top perspective view of table T with table top 1 and back panel 13 removed, and FIG. 10 is a bottom perspective view of table T.

As described above, according to the configuration of this embodiment, the air above the tabletop 1 is led to the dust collection unit 4 through the opening 1x of the tabletop 1 that is open upward and the air introduction path 5. Therefore, even if the air above the tabletop 1 contains dust or saliva particles with viruses attached, the dust and saliva particles are led to the dust collection unit 4 together with the air, and the air from which the dust and saliva particles have been removed is discharged from the dust collection unit 4. In addition, since the air introduction path 5 is connected to the outside only through the opening 1x of the tabletop 1, dust and saliva particles do not leak to the outside on the way from the opening 1x of the tabletop 1 to the dust collection unit 4. This makes it possible to meet the demand for a conference room in which this table T is installed to be a place for safe, close communication.

In addition, a partition plate 91 is arranged to stand up from the edge of the opening 1x of the tabletop 1 and surround the opening 1x, and air is guided to the air introduction passage 5 via the upper air introduction passage 9 that is separated by this partition plate 91 and opened upward, so that more air above the tabletop 1 and more suspended matter in the air can be guided to the dust collection unit 4. In addition, because this partition plate 91 is transparent, communication between people seated on either side of the partition plate 91 can be facilitated.

Below the top plate 1 is a storage section S for storing the dust collection unit 4, and this storage section S has a dust collection unit support frame 8 that supports the dust collection unit 4 while keeping it away from the floor surface F, so that the air taken in by the dust collection unit 4 from above the top plate 1 can be smoothly discharged downward with any floating objects removed.

Below the top plate 1, a pair of dust collection unit covers 51 are provided, one in front and one in back, which are in surface contact with the dust collection units 4 and close the space between the underside of the top plate 1 and the dust collection units 4. The space between the dust collection units 4 is closed by a horizontal plate-like member, a lid body 52, which serves as the underside of the air introduction passage 5. This allows the air introduction passage 5 to be configured using the space between the underside of the top plate 1 and the upper surface of the dust collection units 4 with a simple structure.

A panel 10 is arranged below the top plate 1 to conceal the dust collection unit 4 from the outside space, so the dust collection unit 4 is not exposed to the outside, and the appearance of the table T can be improved.

A lower exhaust port 10a is provided at the lower edge of the fascia panel 10 to allow exhaust air from the dust collection unit 4 to circulate, and an upper exhaust port 10b is provided at the upper edge of the fascia panel 10 to allow exhaust air from the dust collection unit 4 to circulate, improving the efficiency of exhaust from the dust collection unit 4 and thus increasing the efficiency of air intake above the top panel 1 by the dust collection unit 4.

And because there are multiple air flow openings below the top plate 1 and above the dust collection unit 4, and a horizontal partition plate 50 is provided to separate the air inlet passage 5 and the upper air inlet passage 9, even if an item falls into the upper air inlet passage 9, the fall can be prevented by the horizontal partition plate 50.

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

For example, the shape of the tabletop is not limited to a trapezoidal shape as in the above-described embodiment, but may be rectangular, circular, elliptical, or other suitable shape. In addition, the tabletop is not limited to a tabletop formed by combining multiple plate-like members as in the above-described embodiment, but may be a single plate-like tabletop with an opening at a suitable position, for example, in the center in the depth direction.

In the above-described embodiment, a horizontal partition plate having multiple air flow openings is provided below the top plate and above the dust collection unit. In such a configuration, it is preferable to make the horizontal partition plate as described below in order to increase the efficiency of air intake into the dust collection unit. In other words, it is preferable to make the opening rate of the horizontal partition plate larger in other areas than directly above and near the dust collection unit.

In the above-described embodiment, the outer surface of the partition plate that forms the upper air intake passage may be provided with an option mounting portion to which optional components such as a small display shelf for placing plants or a power outlet can be attached.

On the other hand, there are also configurations that do not have an upper air intake passage. One example of such a configuration is one in which a panel is erected at the center of the depth direction of the opening in the top plate, and air can be drawn into the dust collection unit from both sides of the space above the top plate divided by the panel.

The location of the power outlet is not limited to the underside near the usable end of the tabletop as in the above-mentioned embodiment, or to the outer surface of the partition plate as described above, but may be, for example, midway between the opening of the tabletop and the usable edge. In this case, if the power outlet is of a pop-up type that can be placed in a usable position with its upper surface flush with the tabletop surface when not in use, this is desirable in that it allows the seated person to use a larger area of the tabletop surface.

In the above-described embodiment, a lower exhaust port is provided at the lower edge of the fascia board, and an upper exhaust port is provided at the upper edge of the fascia board, but the location of the upper exhaust port is not limited to the upper edge of the fascia board. In other words, an opening may be provided at the midpoint of the fascia board in the height direction, and this opening may be used as the upper exhaust port. Furthermore, in some cases, the fascia board itself may be omitted.

On the other hand, if the dust collection unit exhausts downward and an upper exhaust port is provided on the fascia, it is preferable to provide an exhaust guide element that guides part of the exhaust air from the dust collection unit to the upper exhaust port. Providing such an exhaust guide element can improve the exhaust efficiency from the dust collection unit, and thus improve the intake efficiency of the dust collection unit.

In addition, in the above-described embodiment, a dust collection unit cover is provided to close the space between the underside of the top plate and the dust collection unit, separate from the top plate support frame that supports the top plate. However, it is of course also possible to adopt a configuration in which part of the top plate support frame also serves as the dust collection unit cover.

Various modifications may be made without departing from the spirit of the present invention.
