Description

The present invention relates to panel furniture and booth furniture that constitutes booth furniture that can be used for personal office work or tasks, for example in offices, public facilities, etc.

In offices, public facilities, etc., booths that include left and right side panels and a back panel that connects one end of these side panels are known as spaces for individual office work or work (see, for example, Patent Document 1). Inside the booth, a tabletop is arranged along the left and right side panels and the back panel, creating a space where users who are seated facing the tabletop can concentrate on their office work or work without being distracted by their surroundings.

Patent No. 4804939

One example of booth furniture with panel materials is one that includes a pair of side panels arranged opposite each other and a back panel connected between one end of the side panels. The booth furniture is self-supporting because it is U-shaped when viewed from above, and forms an interior booth space that serves as living space. In booth furniture, a curved cover is attached to the butted corners where the side panels and back panel are joined at right angles.

In addition, multiple booth furniture pieces may be combined to be used as a booth unit. For example, in a booth unit consisting of two booth furniture pieces connected vertically, if the rear panel is made of a single shared panel material, the two side panels are connected to the rear panel in an approximately T-shape. In this case, a flat cover is attached to the butt corner where the two side panels and the rear panel are connected.

Therefore, a structure is needed that allows optional parts such as curved covers or flat covers to be easily attached to the edge of the panel material.

The present invention was made with an eye on these issues, and aims to create new panel furniture and booth furniture that allows optional parts to be easily attached to the edges of the panel material.

To achieve this objective, the present invention takes the following measures:

In other words, the panel furniture of the present invention has a fixture that can be attached and detached to the edge of the panel material and that allows optional parts to be attached from a 90-degree or 135-degree direction to the panel surface of the panel material, and the fixture has first to third legs that extend radially in three directions from a central portion, and the second and third legs extend at 90 degrees and 135 degrees, respectively, to the first leg.

This makes it easy to attach optional parts to the edge of the panel material using mounting fixtures.

In the panel furniture of the present invention, it is preferable that the panel material has a vertical peripheral groove formed on the left and right edges, and at least one of the legs of the mounting fixture is in the form of a plate that is inserted into this vertical peripheral groove.

In this way, when attaching the fixture to the edge of the panel material, the fixture can be firmly fixed to the edge of the panel material by inserting the plate-shaped legs. In addition, the attachment position of the fixture can be guided by the peripheral grooves formed on the left and right edges of the panel material.

In the panel furniture of the present invention, the mounting fixture preferably has legs at 90 degrees to the first leg and 135 degrees from there in the same direction, and when turned upside down, it has a symmetrical shape.

By doing this, the fixture will be configured to have a symmetrical shape when flipped upside down, so the same fixture can be used on both the left and right.

In the panel furniture of the present invention, it is preferable that the optional part is a cover having two sets of parallel U-shaped engaging parts that engage with the legs of the mounting fixture.

In this way, the fixture and optional part can be attached simply by inserting the engaging part of the optional part into the leg of the fixture from one direction.

In the panel furniture of the present invention, the optional part is preferably a cover that is attached to the butt corner of two panels that are joined at a right angle.

This makes it easy to attach the cover to the butt corner of two panels that are joined at a right angle.

In the panel furniture of the present invention, the optional part is preferably a cover that is attached to the butt corner of three panels connected in a roughly T-shape.

This makes it easy to attach the cover to the butt corners of three panels that are connected in a roughly T-shape.

In the panel furniture of the present invention, it is preferable that when the cover is attached to the butt corner portion, the mounting fixture is covered by the cover and cannot be seen from the outside.

This improves the appearance of the butt corners because the fittings are covered and cannot be seen from the outside.

In the panel furniture of the present invention, it is preferable that the upper ends of the adjacent panel materials at the butt corner portion are connected by a connector, and that the inner surface of the cover is formed with a locking protrusion that locks onto the upper surface of the connector when attached to the butt corner portion.

This prevents the cover from moving downwards when it is attached to the butt corner portion.

The booth furniture of the present invention is characterized in that multiple pieces of panel furniture as described above are connected in a U-shape to form an interior space with at least one side open.

In this way, optional parts can be easily attached to the edge of the panel furniture included in the booth furniture via mounting fixtures.

The present invention makes it easy to attach optional parts to the edge of the panel material.

The following describes an embodiment of the present invention with reference to the drawings.

First Embodiment
Fig. 1 is a perspective view of the booth furniture 1 according to the first embodiment of the present invention, Fig. 2 is a front view of the booth furniture 1 in Fig. 1, Fig. 3 is a plan view of the first booth, and Fig. 4 is a cross-sectional view of the booth furniture 1 in Fig. 1. Note that the cross-sectional view of Fig. 4 does not show two chairs 2. Fig. 5 is an exploded perspective view of the booth furniture 1, showing only the main parts.

The booth furniture 1 shown in Figures 1 to 4 includes a pair of side panels 10, 11 arranged opposite each other, and a back panel 12 connected between one end (rear end) 10a, 11a of these side panels 10, 11, and is U-shaped in plan view, making it self-supporting, forming an interior booth space S1 that serves as living space. Two chairs 2 are arranged inside the booth furniture 1. The two chairs 2 are arranged along the inner surfaces of the side panels 10, 11, respectively.

The side panels 10, 11 and the back panel 12 are each made of panel material of approximately the same shape, and are horizontally elongated rectangular shapes with a relatively large width. The other ends (front end parts) 10b, 11b of the side panels 10, 11 are connected to the front panels 13a, 13b. The front panels 13a, 13b are each made of panel material of approximately the same shape, and are vertically elongated rectangular shapes with a relatively small width.

The front panels 13a and 13b are arranged to face the rear panel 12, and their width is smaller than the width of the rear panel 12. Therefore, the space between the front panels 13a and 13b is an opening OP for users to enter and exit the booth space S1. The side panels 10 and 11, the rear panel 12, and the front panels 13a and 13b are set to the same height.

As shown in Figures 5 and 6, cutouts 10c, 11c, and 12c are formed at the upper ends of both horizontal ends of the side panels 10 and 11 and the back panel 12. Similarly, cutouts 13c and 13c are formed at the upper ends of one horizontal end side (the side connected to the side panels 10 and 11) of the front panels 13a and 13b.

The upper ends of the butt corners of the side panels 10, 11 and the back panel 12, the upper ends of the butt corners of the front panel 13a and the side panel 11, and the upper ends of the butt corners of the front panel 13b and the side panel 11 are each connected by fastening bolts 14a using L-shaped connectors 14 in a plan view as a simple connection means.

For example, the upper ends of the butt corners of the side panel 10 and the rear panel 12 are connected by fastening bolts 14a with connectors 14 that are L-shaped in plan view placed in the cutouts 10c of the side panel 10 and the cutouts 12c of the rear panel 12 as shown in FIG. 6(a). Then, as shown in FIG. 6(b), the cutouts 10c of the side panel 10 and the cutouts 12c of the rear panel 12 are closed by placing lids 15.

Although detailed explanations are omitted, the bottom ends of the butt corners of the side panels 10, 11 and the back panel 12, the bottom ends of the butt corners of the front panel 13a and the side panel 11, and the bottom ends of the butt corners of the front panel 13b and the side panel 11 are also connected by bolts using L-shaped connectors (not shown) as a simple connection means.

On the sides of the booth furniture 1, covers (end covers) 16 extending in the vertical direction are attached to the butt corners of the side panels 10, 11 and the back panel 12, the butt corners of the front panel 13a and the side panel 11, and the butt corners of the front panel 13b and the side panel 11.

Adjusters 3 are attached to the bottom ends of the side panels 10 and 11 at three equally spaced locations, the rear panel at four locations in the center, and the front panels 13a and 13b at one location on the end of the opening OP side, as ground contact members to adjust the ground contact height.

In the booth furniture 1, as shown in Figs. 1 and 4, an upper panel 31 is provided above the booth interior space S1, extending from near the upper ends of the side panels 10 and 11 toward the inside of the booth interior space S1. The upper panel 31 is inclined so as to be positioned upward as it moves away from near the upper ends of the side panels 10 and 11. The upper end of the upper panel 31 is positioned at approximately the same height as the upper ends of the side panels 10 and 11. In addition, the lower end of the upper panel 31 contacts the inner surfaces of the side panels 10 and 11 below the upper ends of the side panels 10 and 11. In addition, as will be described later, a block portion 51 surrounded by two sets of grooves 50 extending approximately parallel to each other is formed on the inner surface of the back panel 12, and the base portion of the upper panel 31 is positioned so as to correspond to the grooves 50 extending horizontally on the inner surfaces of the side panels 10 and 11.

The top panel 31 is attached to the top of the side panels 10, 11, which are above the two chairs 2 arranged along the inner surfaces of the side panels 10, 11 in the booth interior space S1. The top panel 31 at the top of the side panel 10 faces the chair 2 arranged at the bottom of the opposing side panel 11, effectively absorbing the voices of the person sitting in the opposing chair. The top panel 31 at the top of the side panel 11 and the chair 2 at the bottom of the side panel 10 are in the same relationship, so that the booth interior space S1 contains two sets of top panels 31 and chairs 2 arranged opposite each other. This provides a sound absorption effect that effectively reduces the voices of people talking while seated in the booth from leaking upwards.

To attach the top panel 31, brackets 32 are provided near the upper ends of the front and back ends of the side panel 10, as shown in FIG. 7(a). The brackets 32 are fastened with bolts 33 to the outer peripheral grooves 60a formed in the front and back ends of the side panel 10, respectively.

As shown in FIG. 7(b), both ends of the top panel 31 are held on the brackets 32, so that the top panel 31 is held near the upper end of the side panel 10. The top panel 31 that is held near the upper end of the side panel 11 is also attached in the same manner.

The structures of the side panels 10, 11, the rear panel 12, the front panels 13a, 13b, and the top panel 31 will be described. Note that in this embodiment, the structure of the rear panel 12 shown in FIG. 8 will be described in detail, but the structures of the side panels 10, 11, the front panels 13a, 13b, and the top panel 31 are also similar.

The inner surface of the rear panel 12 (the surface facing the booth interior space S1) is a panel material having a panel structure in which multiple block sections 51 surrounded by two sets of grooves 50 extending approximately parallel to each other are arranged vertically and horizontally through the grooves 50, as shown in FIG. 8(a). The block sections 51 are rectangular and are arranged over the entire inner surface of the rear panel 12.

Specifically, as shown in FIG. 8(b), the back panel 12 has a lightweight core material 60 such as paper honeycomb, MDF 61 (Medium Density Fiberboard) provided on one side of the core material 60, MDF 62 provided on the other side of the core material 60, a surface material 63 provided to cover the MDF 61, and an upholstery material (upholstery) 64 provided to cover the MDF 62.

The core material 60 is a member disposed inside the rear panel 12. As described above, the upper surface of the rear panel 12 has cutouts 12c at both ends, which are formed at both ends of the upper surface of the core material 60. In addition, the cutouts 12c have bolt holes 60c formed therein for fastening the connector 14 with bolts 14a, as shown in Figures 9(a) and 9(b).

A linear peripheral groove 60a is formed on the upper end surface of the core material 60 between the two cutouts 12c. The peripheral groove 60a is formed in the center of the thickness direction of the core material 60 as shown in FIG. 9(b). Similarly, two cutouts 12c are formed on both ends of the lower end surface of the core material 60, and a peripheral groove 60a is formed between the two cutouts 12c. Similarly, linear peripheral grooves 60a are formed on the left and right end surfaces of the core material 60 in the center of the thickness direction of the core material 60 as shown in FIG. 9(c).

As shown in FIG. 8(b), the surface material 63 is composed of three layers: nonwoven fabric 52 arranged on the MDF 61, sound-absorbing material (urethane) 53 with convex stripes, and upholstery material 54 covering the surface of the sound-absorbing material 53. Therefore, the block portion 51 is composed of the area surrounded by two sets of grooves 50 that extend approximately parallel to each other, the nonwoven fabric 52, the sound-absorbing material 53, and the upholstery material 54.

In this way, in the rear panel 12, the block portion 51 is arranged on only one side of the rear panel 12, and the surface on which the block portion 51 is arranged becomes the inner surface of the booth interior space S1. Note that, in the side panels 10, 11 and the front panels 13a, 13b, the block portion 51 is also arranged on only one side. In the top panel 31, the block portion 51 is arranged on both sides.

As a result, as shown in FIG. 1, the side panels 10, 11, rear panel 12, and front panels 13a, 13b are provided with convex sound absorbing material 53 in the portions facing the booth interior space S1 of the booth furniture 1, and the convex sound absorbing material 53 is not provided in the portions not facing the booth interior space S1. Note that the top panel 31 is provided with convex sound absorbing material 53 in the portions facing the booth interior space S1 of the booth furniture 1 and in the portions not facing the booth interior space S1.

The procedure for installing the three-layer surface material 63 described above to cover the MDF 61 installed on the core material 60 will be explained with reference to Figure 10.

The surface layer 63 has a three-layer structure of nonwoven fabric 52, sound-absorbing material 53, and upholstery material 54, and is formed to be longer than the length of the core material 60. Therefore, the surface layer 63 is cut according to the length of the core material 60, such as the back panel 12, before use.

First, bring the surface material 63 close to the MDF 61 provided on the core material 60, and check that the groove 50A at the end of the block portion 51 is aligned along the end 60A of the core material 60, as shown in FIG. 10(a).

Then, as shown in FIG. 10(b), the nonwoven fabric 52 and the sound absorbing material 53 are cut along the groove 50A at the end of the block portion 51. At this time, the upholstery material 54 is not cut along the groove 50A at the end of the block portion 51. Therefore, the upholstery material 54 covering the surface of the block portion 51 extends outward beyond the end 60A of the core material 60. As will be described later, the upholstery material 54 is cut to a length that allows its end to be pushed into the peripheral groove 60a formed on the end face of the core material 60.

The surface layer 63, which is made by cutting the nonwoven fabric 52 and sound absorbing material 53 according to the length of the core material 60, is placed on the surface of the MDF 61 provided on the core material 60 so that the groove 50A at the end of the block portion 51 coincides with the end 60A of the core material 60. In this state, as shown in FIG. 10(c), the end of the upholstery material 54 is pushed into the peripheral groove 60a formed on the end face of the core material 60. Then, the surface layer 63 is attached without any gaps to the surface of the MDF 61 provided on the core material 60.

The procedure for providing the upholstery material 64 to cover the MDF 62 provided on the core material 60 on the side opposite to the side on which the surface layer 63 of the core material 60 is provided is similar. That is, the upholstery material 64 is cut according to the length of the core material 60, and the upholstery material 64 is placed on the surface of the MDF 62 provided on the core material 60. In this state, the end of the upholstery material 64 is pushed into the peripheral groove 60a formed on the end face of the core material 60. Then, the upholstery material 64 is attached to the surface of the MDF 62 provided on the core material 60 without any gaps.

As described above, covers 16 extending in the vertical direction are attached to the butt corners of the side panels 10, 11 and the back panel 12, the butt corners of the front panel 13a and the side panel 10, and the butt corners of the front panel 13b and the side panel 11 on the sides of the booth furniture 1. The covers 16 are of the 90-degree R type that are attached to the butt corners of two panels connected at a right angle.

The method of attaching the cover 16 to the booth furniture 1 will be described below with reference to Figures 11 to 16. In this embodiment, a method of attaching the cover 16 to the butt corner portion of the side panel 10 and the back panel 12 will be described, but the method of attaching the cover 16 to other butt corner portions is similar.

Figure 11 shows the booth furniture 1 with the cover 16 attached to the butt corner portion of the side panel 10 and the back panel 12. When the cover 16 is pulled in a direction away from the butt corner portion, the cover 16 is removed from the butt corner portion as shown in Figure 12.

When the cover 16 is removed from the butt corners, multiple mounting fixtures 80 for attaching the cover 16 to the edges of the side panel 10 and the back panel 12 become visible. Figure 13 shows the state in which the multiple mounting fixtures 80 have been removed from the edges of the side panel 10 and the back panel 12. The mounting fixtures 80 are configured to be detachable from the edges of the core material 60 of the side panel 10 and the back panel 12.

As shown in FIG. 14(a), the mounting fixture 80 has a cylindrical central portion 80a, a first leg portion 81, a second leg portion 82, and a third leg portion 83. The first to third legs 81 to 83 are each formed in a plate shape and extend radially in three different directions from the central portion 80a. The first leg portion 81 is inserted into the peripheral groove 60a formed in the edge portion of the core material 60. Therefore, the outer peripheral surface of the first leg portion 81 is formed into a shape that makes it difficult for it to come out of the peripheral groove 60a.

As shown in FIG. 14(b), the second leg 82 extends at an angle of 90 degrees to the first leg 81, and the third leg 83 extends at an angle of 135 degrees to the first leg 81. The second leg 82 and the third leg 83 are disposed on the opposite side of the first leg 81.

As described above, at the edge portions of the side panel 10 and the back panel 12, the ends of the upholstery materials 54, 64 are pressed into the peripheral groove 60a formed in the end face of the core material 60, and the first leg 81 is inserted into the peripheral groove 60a to be attached to the end face of the core material 60. In this state, the first leg 81 is positioned between the upholstery materials 54 and 64 within the peripheral groove 60a.

The fixture 80 has a second leg 82 and a third leg 83 at a position 90 degrees from the first leg 81 and 135 degrees from there in the same direction. Therefore, when the fixture 80 is turned upside down, it has a symmetrical shape. This allows the same parts to be used for the fixture 80 to be attached to the edge of the side panel 10 and the fixture 80 to be attached to the edge of the back panel 12.

As shown in FIG. 15, the cover 16 has a curved cover body 16a. Two mounting parts 16b extending parallel to each other in the vertical direction are formed on the inner surface of the cover body 16a. The mounting parts 16b have two plate-shaped members extending in the vertical direction that protrude from the inner surface of the cover body 16a. At the tip of the mounting parts 16b, mounting grooves 16c are formed that extend in the vertical direction over the entire vertical area of the mounting parts 16b. In this way, the cover 16 has two sets of mounting grooves 16c with a U-shaped cross section arranged in parallel as engagement parts for the legs of the mounting fixture 80.

When attaching the cover 16 to the butt corners of the side panel 10 and the back panel 12, first, multiple mounting fixtures 80 are attached to the edge portions of the core material 60 of the side panel 10 and the back panel 12 as shown in FIG. 12. In this case, for example, the multiple mounting fixtures 80 are attached at a height position separated vertically from the edge portion of the core material 60 of the side panel 10. Also, the multiple mounting fixtures 80 are attached to the edge portion of the core material 60 of the back panel 12 at a height position approximately the same as the height position at which the mounting fixtures 80 are attached to the edge portion of the core material 60 of the side panel 10. In FIG. 12, four mounting fixtures 80 are attached to each of the edge portions of the side panel 10 and the back panel 12.

16(a) shows a horizontal cross section at a height position where the mounting fixture 80 is attached to the edge portion of the core material 60 of the side panel 10 and the back panel 12. In the horizontal cross section of FIG. 16(a), one mounting fixture 80 is attached to the edge portion of the core material 60 of the side panel 10, and one mounting fixture 80 is attached to the edge portion of the core material 60 of the back panel 12. At this time, the third leg 83 of the mounting fixture 80 attached to the edge portion of the side panel 10 faces in a 135 degree direction with respect to the panel surface of the side panel 10. Similarly, the third leg 83 of the mounting fixture 80 attached to the edge portion of the back panel 12 extends in a 135 degree direction with respect to the panel surface of the back panel 12.

In this state, as shown in FIG. 16(b), the cover 16 is attached from the direction in which the third leg 83 of the fixture 80 attached to the edge portions of the side panel 10 and the back panel 12 extends. Specifically, the cover 16 is attached to the butt corner portion of the side panel 10 and the back panel 12 so that the third leg 83 of the fixture 80 is positioned within the mounting groove 16c formed on the inner surface of the cover 16. In the booth furniture 1 of this embodiment, when the cover 16 is attached to the butt corner portion, the fixture 80 is covered by the cover 16 and cannot be seen from the outside.

As shown in FIG. 15, the inner surface of the cover body 16a has locking projections 16t formed near the upper end and the lower end. The locking projections 16t are formed to protrude from the inner surface of the cover body 16a. The two locking projections 16t are both of the same shape, and are substantially rectangular plate-like members. When the cover 16 is attached to the butted corner portions so as to extend vertically, the lower surface of the locking projections 16t is positioned substantially horizontally.

Therefore, when the cover 16 is attached to the butt corner portion of the side panel 10 and the back panel 12, the cover 16 is attached so that the underside of the locking projection 16t formed near the upper end of the cover body 16a contacts the upper surface of the connector 14 that connects the upper ends of the butt corner portions of the side panel 10 and the back panel 12. This allows the underside of the locking projection 16t of the cover 16 to be locked to the upper surface of the connector 14, preventing the cover 16 from moving downward.

When the cover 16 is attached to the butt corner portion of the side panel 10 and the back panel 12, the locking projection 16t formed near the bottom end of the cover body 16a is positioned below and away from the connector 14 that connects the bottom ends of the butt corner portion of the side panel 10 and the back panel 12. In this embodiment, the two locking projections 16t are formed near the top and bottom ends of the cover body 16a so that the cover 16 can be attached to the butt corner portion of the side panel 10 and the back panel 12 even if it is inverted vertically.

As described above, the bracket 32 for mounting the top panel 31 is secured to the outer peripheral groove 60a formed on the front end and rear end of the side panel 10 by the bolt 33 as shown in FIG. 17(a). As shown in FIG. 17(b), the bolt 33 is fastened to the bolt hole 60a1 formed on the bottom surface of the outer peripheral groove 60a, thereby mounting the bracket 32.

As explained above, the booth furniture 1 of this embodiment is a booth furniture in which the side panels 10, 11 and the back panel 12 are connected in a U-shape to form an internal space with at least one side open, and has a mounting fixture 80 that can be attached and detached to the edge portions of the side panels 10, 11 and the back panel 12 and is used to attach the cover 16 from a 90-degree or 135-degree direction relative to the panel surface. The mounting fixture 80 has first to third legs 81-83 that extend radially in three directions from a central portion 80a, and the second leg 82 and third leg 83 extend at 90 degrees and 135 degrees, respectively, relative to the first leg 81.

In this way, optional parts such as the cover 16 can be easily attached to the edge portions of the side panels 10, 11 and the back panel 12 included in the booth furniture 1 via the mounting fixtures 80.

In this embodiment of the booth furniture 1, the side panels 10, 11 and the rear panel 12 have vertical peripheral grooves 60a formed on the left and right edges, and the first leg 81 of the mounting fixture 80 is in the form of a plate that is inserted into the vertical peripheral grooves 60a.

In this way, when attaching the fixture 80 to the edge portions of the side panels 10, 11 and the rear panel 12, the fixture 80 can be firmly fixed to the edge portions of the side panels 10, 11 and the rear panel 12 by inserting the plate-shaped first leg portion 81. In addition, the attachment position of the fixture 80 can be guided by the peripheral grooves 60a formed on the left and right edges of the side panels 10, 11 and the rear panel 12.

In this embodiment of the booth furniture 1, the fixture 80 has a second leg 82 at a position 90 degrees from the first leg 81, and a third leg 83 at a position 135 degrees from there in the same direction, resulting in a symmetrical shape when turned upside down.

In this way, the mounting fixture 80 is configured to have a symmetrical shape when flipped upside down, so the same mounting fixture 80 can be used on both the left and right sides.

In this embodiment of the booth furniture 1, the cover 16, which is an optional part, has two parallel sets of engagement parts with a U-shaped cross section that engage with the legs of the mounting fixture 80.

In this way, the mounting fixture 80 and the cover 16 can be attached simply by inserting the engaging portion of the cover 16 into the leg of the mounting fixture 80 from one direction.

In the booth furniture 1 of this embodiment, the cover 16, which is an optional part, is attached, for example, to the butt corner portion of the side panel 10 and the back panel 12, which are connected at a right angle.

This makes it easy to attach the cover to the butt corner of two panels that are joined at a right angle.

In the booth furniture 1 of this embodiment, when the cover 16 is attached to the butt corner portion of the side panel 10 and the back panel 12 that are connected at a right angle, the mounting fixture 80 is covered by the cover 16 and cannot be seen from the outside.

In this way, the mounting fixture 80 is covered by the cover 16 and cannot be seen from the outside, improving the appearance of the butt corner portion.

In the booth furniture 1 of this embodiment, for example, the upper ends of adjacent side panels 10 and rear panels 12 at the butt corners of the side panels 10 and rear panels 12 are connected by connectors 14, and the inner surface of the cover 16 is formed with a locking protrusion 16t that locks onto the upper surface of the connector 14 when attached to the butt corners.

This prevents the cover 16 from moving downwards when it is attached to the butt corner portion.

Second Embodiment
The booth furniture 101 of this embodiment differs from the booth furniture 1 of the first embodiment mainly in that, in the first embodiment, the booth furniture 1 is used alone, whereas in this embodiment, two booth furniture 101 are used as a booth unit. In the configuration of the booth furniture 101 of this embodiment, detailed description of the parts similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

Two booth furniture pieces 101 are connected vertically to form a booth unit. Booth furniture pieces 101a and 101b have the same configuration, and one back panel 112 is shared between booth furniture pieces 101a and 101b.

The booth furniture 101 shown in Figures 18 and 19 includes a pair of side panels 110, 111 arranged opposite each other, and a rear panel 112 connected between one end (rear end) 110a, 111a of these side panels 110, 111, and is U-shaped in plan view, making it self-supporting, forming an interior booth space S101 that serves as a living space inside. A table 102 is arranged inside the booth furniture 101. The top plate 102a of the table 102 is rectangular and is arranged along the inner surfaces of the side panels 110, 111 and the inner surface of the rear panel 112.

The width of the side panels 110, 111 and the rear panel 112 is smaller than the width of the side panels 10, 11 and the rear panel 12 of the first embodiment. The structure of the side panels 110, 111 and the rear panel 112 is substantially the same as the structure of the side panels 10, 11 and the rear panel 12 of the first embodiment.

In the booth furniture 101, as shown in Figs. 18 and 19, an upper panel 131 is provided above the booth interior space S101, extending from near the upper end of the rear panel 112 toward the inside of the booth interior space S101. The upper panel 131 is inclined so that it is positioned upward as it moves away from the rear panel 112. The upper end of the upper panel 131 is positioned at approximately the same height as the upper end of the rear panel 112. In addition, the lower end of the upper panel 131 is in contact with the inner surface of the rear panel 112 below the upper end of the rear panel 112.

In the booth furniture 101, as shown in FIG. 18, a top panel 131 is disposed near the upper end of the rear panel 112. In order to attach the top panel 131, brackets (not shown) are provided near the upper ends of the left and right ends of the rear panel 112, as in the first embodiment. Both ends of the top panel 131 are held on the brackets, so that the top panel 131 is held near the upper end of the rear panel 112.

The top panel 131 is attached to the top of the back panel 112, which is above the top plate 102a of the table 102 arranged along the inner surface of the back panel 112 of the booth interior space S110. The top panel 131 at the top of the back panel 112 is arranged above the top plate 102a, so that it effectively absorbs the voice of the person sitting in the chair in front of the table 102 that is reflected upward by the top plate 102a. This provides a sound absorption effect that effectively reduces the voices of people talking in a web conference or the like while seated in the booth from leaking upward.

In this embodiment, a cover (end cover) 116 extending in the vertical direction is attached to the butt corner portion between the side panels 10, 11 and the rear panel 12 on the side of the booth unit. The cover 116 is a 3-way flat plate type that is attached to the butt corner portion of three panel materials connected in a roughly T-shape. When attaching the cover 116 to the butt corner portion, the same mounting fixture 80 as in the first embodiment is used.

The following describes how to attach the cover 116 to the butt corners of the side panels 10, 11 and the rear panel 12, with reference to Figure 19.

As shown in FIG. 19, the cover 116 has a flat cover body 116a. Two mounting parts 116b extending parallel to each other in the vertical direction are formed on the inner surface of the cover body 116a. The mounting parts 116b are formed so as to protrude from the inner surface of the cover body 116a. At the tip of the mounting part 116b, a mounting groove 116c is formed that extends in the vertical direction over the entire vertical area of the mounting part 116b.

When attaching the cover 116 to the butt corners of the side panels 10, 11 and the rear panel 12, first, the multiple mounting fixtures 80 are attached to the edge portions of the core material 60 of the side panels 110, 111. In this case, for example, the multiple mounting fixtures 80 are attached to the edge portion of the core material 60 of the side panel 110 at a height position spaced apart in the vertical direction. Also, the multiple mounting fixtures 80 are attached to the edge portion of the core material 60 of the side panel 111 at a height position substantially the same as the height position at which the mounting fixtures 80 are attached to the edge portion of the core material 60 of the side panel 10.

20(a) shows a horizontal cross section at a height position where the mounting fixture 80 is attached to the edge portion of the core material 60 of the side panels 110 and 111. In the horizontal cross section of FIG. 20(a), one mounting fixture 80 is attached to the edge portion of the core material 60 of the side panel 110, and one mounting fixture 80 is attached to the edge portion of the core material 60 of the side panel 111. At this time, the second leg 82 of the mounting fixture 80 attached to the edge portion of the side panel 110 faces in a 90-degree direction with respect to the panel surface of the side panel 110. Similarly, the second leg 82 of the mounting fixture 80 attached to the edge portion of the side panel 111 extends in a 90-degree direction with respect to the panel surface of the side panel 111.

In this state, as shown in FIG. 20(b), the cover 116 is attached from the direction in which the second leg 82 of the fixture 80 attached to the edge of the side panels 10, 11 extends. Specifically, the cover 116 is attached to the butt corner portion of the side panels 110, 111 and the rear panel 112 so that the second leg 82 of the fixture 80 is positioned within the mounting groove 116c formed on the inner surface of the cover 116. In the booth furniture 101 of this embodiment, when the cover 116 is attached to the butt corner portion, the fixture 80 is covered by the cover 116 and cannot be seen from the outside.

In addition, like the cover 16 of the first embodiment, the inner surface of the cover body 116a has locking protrusions (not shown) formed near the upper and lower ends. Therefore, when the cover 116 is attached to the butted corners of the side panels 110, 111 and the rear panel 12, the lower surfaces of the locking protrusions of the cover 116 are locked to the upper surface of the connector, preventing the cover 116 from moving downward.

In the booth furniture 101, a top panel 131 is attached near the upper end of the back panel 112, and a lighting fixture 135 is attached below it. A table 102 is placed inside the booth furniture 101. The top plate 102a of the table 102 is rectangular and is placed along the inner surfaces of the side panels 110, 111 and the inner surface of the back panel 112.

Therefore, brackets 132 for mounting the top panel 131 are provided near the upper ends of the left and right ends of the rear panel 112. This is similar to the first embodiment in which brackets 32 for mounting the top panel 31 are provided near the upper ends of the front and rear ends of the side panels 10 and 11.

In addition, brackets 136 for mounting the lighting fixture 135 are provided on the left and right ends of the rear panel 112. In this embodiment, the brackets 136 are integrally provided on both ends of the lighting fixture 135.

In addition, near the center of the height direction at the left and right ends of the rear panel 112, a top plate support 103 for supporting the top plate 102a of the table 102 is provided. The rear end of the top plate 102a of the table 102 is supported at both ends by the top plate support 103, and the front end of the top plate 102a is supported at both ends by legs 102c. The two legs 102c are fixed to both ends of the front side of the underside of the top plate 102a.

As shown in FIG. 21, bracket 132a, bracket 136a, and tabletop support 103a for booth furniture 101a, and bracket 132b, bracket 136b, and tabletop support 103b for booth furniture 101b are attached to the left end of the rear panel 112. The same is true for the right end of the rear panel 112.

In this way, when the two brackets 132a, 132b for mounting the top panel 131 are attached back-to-back to the rear panel 112, bracket 132a has mounting portion 132a1, and bracket 132b has mounting portions 132b1, 132b2. In this case, the mounting portion 132a1 of bracket 132a is attached to the left end of the rear panel 112 so that it is positioned between mounting portions 132b1 and 132b2 of bracket 132b in the up-down direction.

In this state, the mounting portion 132a1 of the bracket 132a is secured to the left end of the rear panel 112 by a bolt 133 in the outer circumferential groove 60a formed in the end face of the core material 60, and the mounting portions 132b1 and 132b2 of the bracket 132b are secured to the outer circumferential grooves 60a formed in the end face of the core material 60 by a bolt 133. This allows the brackets 132a and 132b to be attached using the entire thickness of the rear panel 112 without overlapping.

Similarly, when two brackets 136a, 136b for mounting a lighting fixture 135 are attached back-to-back to the rear panel 112, bracket 136a has mounting portions 136a1, 136a2, and bracket 136b has mounting portions 136b1, 136b2. In this case, mounting portion 136a1 of bracket 136a is attached to the left end of rear panel 112 so as to be positioned between mounting portions 136b1 and 136b2 of bracket 136b in the up-down direction. Furthermore, mounting portion 136b2 of bracket 136b is attached so as to be positioned between mounting portions 136a1 and 136a2 of bracket 136a.

Attachment parts 136a1 and 136a2 of bracket 136a are secured to the left end of rear panel 112 by bolts 133 in the outer circumferential grooves 60a formed in the end face of core material 60, and attachment parts 136b1 and 132b2 of bracket 136b are secured to the outer circumferential grooves 60a formed in the end face of core material 60 by bolts 133. This allows brackets 136a and 136b to be attached using the entire thickness of rear panel 112 without overlapping.

Similarly, when two brackets 103a, 103b for mounting the top plate support 103 are attached back to back to the rear panel 112, bracket 103a has mounting parts 103a1, 103a2, and bracket 103b has mounting parts 103b1, 103b2. In this case, mounting part 103a2 of bracket 103a is attached to the left end of the rear panel 112 so as to be positioned between mounting parts 103b1 and 103b2 of bracket 103b in the up-down direction. Furthermore, mounting part 103b1 of bracket 103b is attached so as to be positioned between mounting parts 103a1 and 103a2 of bracket 103a.

Attachment parts 103a1 and 103a2 of bracket 103a are secured to the left end of rear panel 112 by bolts 133 in the outer circumferential grooves 60a formed in the end face of core material 60, and attachment parts 103b1 and 103b2 of bracket 103b are secured to the outer circumferential grooves 60a formed in the end face of core material 60 by bolts 133. This allows brackets 103a and 103b to be attached using the entire thickness of rear panel 112 without overlapping.

As described above, the bracket 132 for mounting the top panel 131, the bracket 136 for mounting the lighting fixture 135, and the bracket 103 for mounting the top plate support 103 are attached to the left end of the rear panel 112, and then the rear end of the side panel 110 is connected to the left end of the rear panel 112.

In this state, when the bracket 132 for attaching the top panel 131 is viewed from inside the booth furniture 101, as shown in FIG. 22(a), the area near the mounting portion of the bracket 132 is hidden by the connection between the rear panel 112 and the side panel 110, making it inconspicuous and neatly stored.

Similarly, when the bracket 103 for mounting the tabletop support 103 is viewed from inside the booth furniture 101, as shown in FIG. 22(b), the area near the mounting portion of the bracket 103 is hidden by the connection between the rear panel 112 and the side panel 110, making it inconspicuous and neatly stored.

In the booth furniture 101 of this embodiment, the cover 116, which is an optional part,
For example, it is attached to the butted corners of side panels 110, 111 and a rear panel 112 which are connected in a substantially T-shape.

In this way, the cover 116 can be easily attached to the butt corners of the side panels 110, 111 and the rear panel 112, which are connected in an approximately T-shape.

As described above, the booth unit having side panels 110, 111 and rear panel 112, which is the panel furniture of this embodiment, provides the same effects as the first embodiment.

Third Embodiment
The booth furniture 201 of this embodiment differs from the booth furniture 1 of the first embodiment mainly in that the booth furniture 1 of the first embodiment is provided with two top panels 31, whereas the booth furniture 201 of this embodiment is not provided with a top panel. A detailed description of the parts of the configuration of the booth furniture 201 of this embodiment that are similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

The booth furniture 201 shown in FIG. 23 includes a pair of side panels 10, 11 arranged opposite each other, and a rear panel 12 connected between one end (rear end) 10a, 11a of these side panels 10, 11, and is U-shaped in plan view, making it self-supporting, forming an interior booth space S1 that serves as a living space inside. A table 202 with a top plate 202a is arranged inside the booth furniture 201. The table 202 is arranged in approximately the center of the interior booth space S1.

In the booth furniture 201 of this embodiment, as shown in FIG. 23, two sets of sound absorbing panels 80A are arranged above the booth interior space S1. Both sets of sound absorbing panels 80A have approximately the same configuration. Each set of sound absorbing panels 80A includes three sound absorbing panels 80a to 80c. The sound absorbing panels 80a to 80c are each suspended from the ceiling via a suspension member 82. The sound absorbing panels 80a to 80c all have the same configuration and are flat plate-like members having an approximately circular shape in a plan view. In the following description, each of the sound absorbing panels 80a to 80c may be simply referred to as a sound absorbing panel 80.

The sound-absorbing panels 80a to 80c are each suspended from the ceiling via a hanging member 81 so that they are positioned above the booth interior space S1. The sound-absorbing panels 80a to 80c are positioned at different horizontal positions in a plan view. That is, the three sound-absorbing panels 80a to 80c are positioned so that they do not overlap in a plan view. The three sound-absorbing panels 80a to 80c are also positioned at different height positions. That is, the sound-absorbing panel 80a is positioned at the lowest height position, followed by the sound-absorbing panels 80b, 80c in order of increasing height positions.

The structure of the sound-absorbing panel 80 is explained with reference to FIG. 24.

The sound-absorbing panel 80 is formed in a substantially circular, flat plate shape. The sound-absorbing panel 80 is configured in the same manner as the back panel 12 described above. That is, the lower surface of the sound-absorbing panel 80 (the surface facing the booth interior space S1) is a panel material having a panel structure in which a plurality of block portions 51 surrounded by two sets of grooves 50 extending substantially parallel to each other are arranged vertically and horizontally through the grooves 50. The block portions 51 are rectangular in shape and are arranged over the entire lower surface of the sound-absorbing panel 80.

Specifically, the sound-absorbing panel 80, like the back panel 12 described above, has a lightweight core material 60 such as paper honeycomb, MDF 61 (Medium Density Fiberboard) provided on one side of the core material 60, MDF 62 provided on the other side of the core material 60, a surface material 63 provided to cover the MDF 61, and an upholstery material (upholstery) 64 provided to cover the MDF 62.

The surface material 63 is composed of three layers: nonwoven fabric 52 placed on the MDF 61, sound-absorbing material (urethane) 53 with convex stripes, and tension material 54 that covers the surface of the sound-absorbing material 53. Therefore, the block portion 51 is composed of the nonwoven fabric 52, sound-absorbing material 53, and tension material 54 in the area surrounded by two sets of grooves 50 that extend approximately parallel to each other.

In this way, in the booth furniture 201 of this embodiment, multiple sound-absorbing panels 80 are arranged above the top plate 202a of the table 202 installed in the booth interior space S1. Therefore, the voices of the occupants seated around the table 202 in the booth furniture 201 are reflected upward by the top plate 202a and are effectively absorbed by the sound-absorbing panels 80.

As described above, the booth furniture 201 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

Fourth Embodiment
The booth furniture 301 of this embodiment differs from the booth furniture 1 of the first embodiment mainly in that the booth furniture 1 of the first embodiment is provided with two top panels 31 and front panels 13a, 13b, whereas the booth furniture 301 of this embodiment is not provided with a top panel or a front panel. A detailed description of the parts of the configuration of the booth furniture 301 of this embodiment that are similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

The booth furniture 301 shown in FIG. 25 includes a pair of side panels 10, 11 arranged opposite each other, and a rear panel 12 connected between one end (rear end) 10a, 11a of these side panels 10, 11, and is U-shaped in plan view, making it self-supporting, forming an interior booth space S1 that serves as a living space inside. A table 302 having a top plate 302a is arranged inside the booth furniture 301. The table 302 is arranged in approximately the center of the interior booth space S1.

Two mounting members 81a and 81b are placed approximately in parallel between the vicinity of the center of the upper end of the side panel 10 and the vicinity of the center of the upper end of the side panel 11. The mounting member 81a is placed on the front side, and the mounting member 81b is placed on the rear side of the booth furniture 1 relative to the mounting member 81a.

In the booth furniture 301 of this embodiment, four sound absorbing panels 380a and four sound absorbing panels 380b are arranged above the booth interior space S1. The four sound absorbing panels 380a and the four sound absorbing panels 380b are arranged at approximately the same height. As shown in FIG. 26, the sound absorbing panels 380a and 380b each have a hole 380c formed at the front end and a hole 380c formed at the rear end. Therefore, the sound absorbing panels 380a and 380b are supported by inserting the mounting member 81a into the hole 380c at the front end and the mounting member 81b into the hole 380c at the rear end.

The sound absorbing panels 380a, 380b are both long, flat members having a predetermined length. The sound absorbing panels 380a and 380b are arranged alternately and approximately parallel to each other in the direction from the side panel 10 toward the side panel 11. When the booth furniture 301 is viewed from the front, the sound absorbing panel 380a is inclined so that its right end is positioned higher than its left end, and the sound absorbing panel 380b is inclined so that its left end is positioned higher than its right end.

In this way, in the booth furniture 301 of this embodiment, the sound absorbing panels 380a, 380b are supported with a gap between them on the mounting members 81a, 81b that span across the upper ends of the opposing side panels 10, 11. As a result, the sound absorbing panels 380a, 380b are positioned above the top plate 302a of the table 302 installed in the booth interior space S1 with a gap between them. Therefore, the voices of the occupants seated around the table 302 in the booth furniture 301 that are reflected upward by the top plate 302a are effectively absorbed by the sound absorbing panels 380a, 380b.

As described above, the booth furniture 301 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

Although the embodiments of the present invention have been described above, the configuration of each part is not limited to the above-described embodiments.

In the first embodiment, the first leg 81 of the mounting fixture 80 is in the form of a plate that is inserted into the outer peripheral groove 60a formed on the left and right edges of the side panels 10, 11 and the rear panel 12, but is not limited to this. When the first leg 81 of the mounting fixture 80 is inserted into the outer peripheral groove 60a, the first leg 81 of the mounting fixture 80 does not have to be formed in a plate shape. Also, the outer peripheral groove 60a may not be formed on the left and right edges of the side panels 10, 11 and the rear panel 12, and the mounting fixture 80 may be attached to the left and right edges of the side panels 10, 11 and the rear panel 12 by a method such as screwing. The same applies to the second to fourth embodiments.

In the first embodiment, an example of the shape of the mounting fixture 80 is shown, but the shape of the mounting fixture 80 is arbitrary. For example, the number, arrangement, and length of the legs of the mounting fixture 80 are arbitrary. The same applies to the second to fourth embodiments.

In the first embodiment, the cover 16 has two parallel sets of mounting grooves (engagement parts) with a U-shaped cross section as engagement parts for the legs of the mounting fixture 80, but this is not limited to this. The configuration of the engagement parts for the legs of the mounting fixture 80 formed on the inner surface of the cover 16 can be arbitrary. The same applies to the second to fourth embodiments.

In the above first embodiment, the optional part, the cover 16, is attached to the left and right edges of the panel material 12P of the rear panel 12 via the mounting fixtures 80, but the optional part that is attached to the edges of the panel material is arbitrary. In other words, it may be an optional part other than the cover 16. The same applies to the second to fourth embodiments.

In the first embodiment, the first leg 81 of the mounting fixture 80 is inserted into the outer peripheral groove 60a formed on the edge of the panel material, and when the mounting fixture 80 is attached to the edge of the panel material, the first leg 81 is disposed between the upholstery material 54 and the upholstery material 64 over its entire length in the outer peripheral groove 60a, but is not limited thereto. For example, as shown in FIG. 28, a groove portion 160a1 having a width smaller than that of the outer peripheral groove 60a is formed on the bottom surface of the outer peripheral groove 60a, and the mounting fixture 180 may be attached to the edge of the panel material by inserting the tip of the first leg 181 of the mounting fixture 180 into the groove portion 160a1. Note that the first leg 181 of the mounting fixture 180 is formed to be longer than the length of the first leg 81 of the mounting fixture 80 in the first embodiment. In that case, the end of the upholstery material 54 and the end of the upholstery material 64 may be disposed in the outer peripheral groove 60a, and may not be disposed in the groove portion 160a1.

In the booth furniture 1 of the first embodiment described above, a wire storage device 360 for fixing wiring T and the like may be attached to the edge of the front panels 13a and 13b. The case where the wire storage device 360 is attached to the edge of the front panel 13a will be described with reference to FIG. 29.
