One embodiment of the present invention will be described below with reference to Figures 1 to 15. Note that Figure 7 is a schematic perspective view primarily used to explain the frame H that constitutes the booth G.

In this embodiment, the present invention is applied to a booth G installed in an office or public space.

The booth G has a booth space sp formed between the front wall 1 and the back wall 2. In this embodiment, as shown in Figures 1 to 7, the booth G has a booth space sp that is isolated to a certain extent from the outside space. The booth space sp is surrounded by the front wall 1, the back wall 2, the first and second side walls 3 and 4, the bottom wall 5, and the top wall 6. Users of the booth G can quickly carry out relatively short work tasks using a computer, smartphone, landline phone, etc., without worrying about external noise or information leaks such as sounds, even in designated locations within the office where the booth G is installed or in public places.

The booth G has a booth space sp inside that can accommodate a user in a standing position. The booth G is equipped with a front wall 1 that covers the front side of the booth space sp, a back wall 2 that covers the back side of the booth space sp, a first side wall 3 equipped with a movable surface material portion i2 that serves as a door covering one side (right side) of the booth space sp, a second side wall 4 that covers the other side (left side) of the booth space sp, a bottom wall 5 that covers the underside of the booth space sp, and a top wall 6 that covers the top side of the booth space sp. A top plate K is provided at a vertically intermediate position on the inner surface of the front wall 1. A buttocks support J without legs is provided at a vertically intermediate position on the inner surface of the back wall 2, protruding from the back wall 2.

The booth G is equipped with frames H to ensure shape retention, and partitioning materials I arranged between the frames H to separate the booth space sp from the outside space. The front wall 1, back wall 2, first and second side walls 3 and 4, bottom wall 5, and top wall 6 are primarily constructed from the partitioning materials I.

As shown in Figures 5-7, the frame H is made, for example, from square pipe material. The frame H has right and left side frame portions h1 formed in annular shapes that correspond to the outer edges of the first and second side walls 3, 4. (Note that the right side frame h1 is located on the right when viewing the booth G from the front, and the left side frame h1 is located on the left when viewing the booth G from the front.) The right and left side frame portions h1 each have a bottom wall corresponding portion h11 extending from the front to the rear, a front wall corresponding portion h12 extending upward from the front end of the bottom wall corresponding portion h11, a back wall corresponding portion h13 extending upward from the rear end of the bottom wall corresponding portion h11, a ceiling wall corresponding portion h14 connecting the upper ends of the back wall corresponding portion h13 and the front wall corresponding portion h12, and an intermediate vertical frame portion h15 connecting the front portion of the ceiling wall corresponding portion h14 to the front portion of the bottom wall corresponding portion h11.

The frame H comprises the top, upper, middle and lower front-side erection frame sections h2a, h2b, h2c and h2d erected between the front wall corresponding portions h12 of the right and left side frame sections h1; the top, upper, middle, lower and lower back-side erection frame sections h3a, h3b, h3c, h3d and h3e erected between the back wall corresponding portions h13 of the right and left side frame sections h1; front and rear bottom-side erection frame sections h4a and h4b erected between the bottom wall corresponding portions h11 of the right and left side frame sections h1; a top-side erection frame section h5 erected between the ceiling wall corresponding portions h14 of the right and left side frame sections h1; and an intermediate erection frame section h6 erected between the intermediate vertical frame portions h15 of the right and left side frame sections h1. The back wall portion h13 is formed in a roughly V-shape in side view, with its vertical center positioned at the rearmost position, corresponding to the height of the buttocks rest J. The bottom wall portion h11 is provided with a mounting plate portion h7. The booth G can be properly fixed to the floor using anchor bolts (not shown) that pass through the mounting plate portion h7.

As shown in Figures 1 to 6 and 8 to 13, the partition panel I comprises a fixed panel member i1 fixed to the outer surface of the front region of the right side frame member h1, a movable panel member i2 which is a door arranged on the outer surface of the rear region of the right side frame member h1, a side panel member i3 arranged on the inside of the left side frame member h1, a front panel member i4 arranged between the front wall corresponding portions h12 of the side frame member h1, upper and lower back panel members i5 and i6 arranged between the back wall corresponding portions h13 of the side frame member h1, a bottom panel member i7 arranged between the bottom wall corresponding portions h11 of the side frame member h1, and a top panel member i8 arranged between the top wall corresponding portions h14 of the side frame member h1.

As shown in Figures 1 to 4 and 6, the fixed surface material portion i1 is, for example, formed by attaching a panel to a frame material (not shown). The fixed surface material portion i1 is fixed to the front of the right side frame portion h1 using an appropriate method. An IC tag reader i11 is provided on the outer surface of the fixed surface material portion i1. One way to use the IC tag reader i11 is to unlock or lock the door, which is the movable surface material portion i2, by bringing an IC card containing registered user information close to the IC tag reader i11.

The movable surface material portion i2 constitutes a door that can be opened and closed. As shown in Figures 1 to 4 and 6, the movable surface material portion i2 is formed, for example, by fitting a glass or synthetic resin panel i22 inside a frame material i21. In this embodiment, the panel i22 used in the movable surface material portion i2 is transparent at the lower portion corresponding to the user's feet, and opaque or frosted glass at the upper portion corresponding to the area above the user's feet. The base end of the movable surface material portion i2 is supported by the fixed surface material portion i1 via a hinge i23. A handle i24 is attached to the tip of the movable surface material portion i2, which the user can use to open and close the door.

As shown in Figures 1, 4, 5, and 6, the side panel i3 is primarily composed of an outer panel i31 and an inner panel i32, both made of sheet metal. The outer panel i31 is attached to the left side frame h1. The inner panel is attached to the outer panel i31 with screws v, sandwiching the middle vertical frame portion h15. If necessary, a sound-absorbing lining material (not shown) can be attached to the inner panel i32 facing the booth space sp.

As shown in Figures 1, 4-6, and 11-13, the front material portion i4 is primarily composed of an outer panel i41 and an inner panel i42, both made of sheet metal. The outer panel i41 is attached to the top front-side erection frame portion h2a and the bottom front-side erection frame portion h2d. The inner panel i42 is attached to the inner surface of the outer panel i41, sandwiching the upper and middle front-side erection frame portions h2b and h2c. The inner panel i42 is fastened to the outer panel i41 using screws v. If necessary, a sound-absorbing lining (not shown) may be attached to the inner surface of the inner panel i42 facing the booth space sp.

As shown in Figures 1, 3-6, and 8-10, the upper backing material portion i5 is primarily composed of an outer panel i51 and an inner panel i52, both made of sheet metal. The outer panel i51 is attached to the top rear-side erection frame portion h3a and the bottom rear-side erection frame portion h3e. The inner panel i52 is attached to the inner surface of the outer panel i51, sandwiching the upper, middle, and lower rear-side erection frame portions h3b, h3c, and h3d. The inner panel i52 is fastened to the outer panel i51 using screws v. If necessary, a sound-absorbing lining (not shown) may be attached to the inner surface of the inner panel i52 facing the booth space sp.

As shown in Figures 1, 3-5, and 10, the lower back material portion i6 is primarily composed of, for example, a sheet metal outer panel i61 and a synthetic resin inner panel i62 with a thickness large enough to withstand the user's weight. The outer panel i61 is attached to the lowest rear-side erection frame portion h3e and the rear bottom-side erection frame portion h4b. The inner panel i62 is positioned facing the inside of the outer panel i61, with its upper end abutting the underside of the lowest rear-side erection frame portion h3e. The lower end of the inner panel i62 is integrally connected to the inner panel of the bottom material portion i7, which will be described later.

As shown in Figures 4 to 6, the bottom material portion i7 is primarily composed of an outer panel i71 made of sheet metal and an inner panel i72 made of synthetic resin with a thickness large enough to withstand the weight of a user. The outer panel i71 is attached to the lower front-side erection frame portion h2d and the front bottom-side erection frame portion h4a. The inner panel i72 is positioned on the underside of the booth space sp with its front end abutting the underside of the lower front-side erection frame portion h2d. The rear end of the inner panel i72 is integrally connected to the inner panel i62 of the lower back material portion i6.

As shown in Figures 1, 4, 5, and 11, the ceiling material portion i8 is primarily composed of an outer panel i81 and an inner panel i82, both made of sheet metal. The outer panel i81 is attached to the upper-side installation frame portion h5 and the uppermost front-side installation frame portion h2a. The inner panel i82 is attached to the inner surface of the outer panel i81. The inner panel i82 is fastened to the outer panel i81 using screws v. If necessary, a sound-absorbing lining material (not shown) may be attached to the inner surface of the inner panel i82 facing the booth space sp.

The configuration of the partitioning surface material I is as described above. The front wall 1 of the booth G is mainly composed of the front surface material portion i4 of the partitioning surface material I. The back wall 2 of the booth G is mainly composed of the upper back surface material portion i5 and the lower back surface material portion i6 of the partitioning surface material I. The first side wall 3 of the booth G is mainly composed of the fixed surface material portion i1 and the movable surface material portion i2. The second side wall 4 of the booth G is mainly composed of the side surface material portion i3. The top wall 6 of the booth G is mainly composed of the top surface material portion i8. The bottom wall 5 of the booth G is mainly composed of the bottom surface material portion i7.

The back wall 2 is inclined so that the portion located below the buttocks rest J gradually shifts forward as it moves downward. In other words, in a side view, the upper portion of the back wall 2, located above the buttocks rest J, extends approximately perpendicular to the floor, while the lower portion, located below the buttocks rest J, is tilted backward.

Next, we will explain about the buttocks pad J.

As shown in Figures 3, 5-7, and 9, the buttocks support J can support the user's buttocks from behind and diagonally below when they lean against the back wall 2. The buttocks support J is primarily made of cushioning material. It is located at the vertical center of the inner surface of the back wall 2. When viewed from the front or back, the buttocks support J has a generally horizontally elongated rectangular shape, and does not have legs interposed between it and the bottom wall 5. The buttocks support J is shorter than the left-right dimension of the back wall 2 and is located in the left-right center of the back wall 2. The front-to-back thickness of the buttocks support J is set so that the lower part j1 is larger than the upper part j2. In other words, the front-to-back thickness of the upper part j2 of the buttocks support J is set smaller than the front-to-back thickness of the lower part j1 of the buttocks support J.

More specifically, the buttocks pad J has a width that corresponds to the width of the buttocks of a typical user. The lower part j1 of the buttocks pad J is shaped to bulge forward so that it can support the user's buttocks from diagonally below, and the upper part j2 is shaped so that it can support the buttocks from behind.

As shown in Figure 9, the rear end of the upper part j2 of the buttocks pad J is fastened to the middle rear-side frame part h3c using a screw v, and the rear end of the lower part j1 is fastened to the lower rear-side frame part h3d using a screw v.

Next, we will explain about the top plate K.

The top plate K is located at the vertically middle position on the inner surface of the front wall 1. The top plate K has an area large enough to accommodate a personal computer, the user's personal belongings, etc. The base end of the top plate K is fastened to the middle front-side installation frame part h2c using screws v. The underside of the tip of the top plate K is fastened to the intermediate installation frame part h6 using screws v.

A touch panel display device L is provided on the inner surface of the front wall 1, above the tabletop K. The display device L has a built-in camera that can capture images of the user, allowing for teleconferencing and other office work.

In addition, a lighting device M is provided on the inner surface of the ceiling wall 6.

When a user pulls the handle i24 to open the movable surface member i2, which serves as the door, the booth space sp is opened to the outside. Users can then enter the booth space sp from outside. Once inside the booth space sp, they can work using the tabletop K or other equipment while simply standing upright, without leaning against the buttocks rest J. Furthermore, when performing work that requires the use of the tabletop K, users can work in a semi-standing position, leaning against the buttocks rest J to support their buttocks. Because the buttocks rest J is positioned behind the rear end of the bottom wall 5 in a side view, the buttocks rest J is recessed in the back wall 2, and the buttocks rest J is less likely to get in the way of the user, even when working while simply standing upright without leaning against it.

As described above, the booth G of this embodiment has a booth space sp inside that can accommodate a user in a standing position. The booth G comprises a front wall 1 that covers the front side of the booth space sp, a back wall 2 that covers the back side of the booth space sp, a first side wall 3 equipped with a movable surface material portion i2 that serves as a door covering one side of the booth space sp, the left side, a second side wall 4 that covers the other side of the booth space sp, the right side, a bottom wall 5 that covers the bottom side of the booth space sp, and a top wall 6 that covers the top side of the booth space sp. A top plate K is provided at a vertically intermediate position on the inner surface of the front wall 1, and a buttocks rest J without legs is provided at a vertically intermediate position on the inner surface of the back wall 2. This allows for the provision of a booth G with excellent design flexibility, allowing for a configuration that at least facilitates user entry and exit from the booth space sp. In other words, because the buttocks rest J, which does not have legs, is provided on the inner surface of the back wall 2, it is possible to advantageously adopt a configuration that makes it easier for the user to enter and exit compared to conventional configurations that have a seat supported by legs.

Furthermore, because users work with their buttocks resting against the buttock rest J, it is possible to effectively prevent them from staying in the booth G for long periods of time. In other words, the booth G in this embodiment allows users to comfortably and effortlessly carry out relatively short work sessions using a personal computer or smartphone within the booth space sp, which is isolated to a certain extent from the outside, while also effectively preventing users from staying in the booth for unnecessarily long periods of time. In other words, this booth G encourages users to use the booth quickly and can adjust the turnover rate to an appropriate value.

The portion of the back wall 2 located below the buttocks rest J is inclined so that it gradually moves forward as it moves downward. This allows the user to easily grasp the front and back of the booth G, as suggested by the shape of the back wall 2, and allows them to adopt an optimal posture when entering the booth space sp.

The booth is equipped with a bottom wall 5 that covers the bottom side of the booth space (sp) and allows the seated occupant to stand on top of it. The portion of the back wall 2 located below the position where the buttocks rest J is attached is inclined downward so that it gradually moves forward, and its lower end is connected to the rear end of the bottom wall 5. The buttocks rest J is set to be located behind the rear end of the bottom wall 5 in a side view. As a result, the buttocks rest J is located in a recessed position in the back wall 2, so it is less likely to get in the way of the user when working in an upright position.

The booth G is equipped with frames H to ensure shape retention, and partitioning materials I that are arranged between the frames H and separate the booth space sp from the outside space. The front wall 1, back wall 2, first and second side walls 3 and 4, bottom wall 5, and top wall 6 are primarily constructed from the partitioning materials I. Therefore, by simply replacing the partitioning materials I with the frames H, it is possible to flexibly accommodate specification changes to suit the installation location, etc.

The buttocks rest J is set shorter than the left-right dimension of the back wall 2 and is positioned in the left-right center of the back wall 2. This makes it difficult for the buttocks rest J to occupy a large area in the booth space sp, making it easier to create a large free area within the booth space sp.

The front-to-back thickness of the upper part j2 of the buttocks pad J is set smaller than the front-to-back thickness of the lower part j1 of the buttocks pad J. This ensures that the user's buttocks are properly supported.

A sound-absorbing lining material (not shown) is provided on the inner surface of the partitioning material I, making it difficult for sounds generated within the booth space sp to be heard from the outside.

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

Of course, the booths are not limited to being used for office work using computers or smartphones, but can also be used simply as telephone booths.

The booth described above is constructed from a frame and partitioning material, but is not limited to this. For example, the booth may be constructed primarily from a shell-shaped component that functions as both a frame and a partitioning material. However, in the embodiment described above, various partitioning materials can be applied to the frame, making it easy to flexibly accommodate specification changes such as the installation of electrical equipment or design changes.

While the above-described embodiment shows a configuration in which only a portion of the upper surface of the booth space is covered by a ceiling wall, this is not limited to this. The ceiling wall may cover the entire upper surface of the booth space. For example, when installing a booth in an office, if installation conditions allow, the ceiling wall of the booth may cover the entire upper portion of the booth space to improve the soundproofing performance of the booth space. On the other hand, the booth may not have a ceiling wall. The booth may be configured so that the presence or absence of a ceiling wall can be selected depending on the installation location. For example, the ceiling wall may be configured to be easily attached and detached from the frame, allowing for selective use of a configuration with or without a ceiling wall (including leaving a portion of the ceiling wall). However, as shown in the above-described embodiment, a configuration in which only a portion of the upper surface of the booth space is open is preferable, as it can achieve a certain degree of isolation from the outside and reduce the feeling of claustrophobia felt by users.

In the above-described embodiment, the mounting plates are attached to the bottom wall-facing portions of the right and left side frame sections, but this is not limited to this. For example, multiple mounting plates extending in the front-to-rear direction may be provided on the bottom wall-facing portions of the right and left side frame sections, or on the bottom-side erection frame section erected between the bottom wall-facing portions of the right and left side frame sections. In this case, to ensure booth stability, it is preferable to position the rear ends of the mounting plates so that they are roughly the same position as the rear end of the back wall in a side view, or further rearward. In this case, the booth can be prevented from tipping over without having to be fixed to the floor using anchor bolts or the like.

In the above-described embodiment, the lower part of the back wall gradually displaces forward as it moves downward, but this is not limited to this. In other words, the back wall may be erected so that it is approximately perpendicular to the floor surface over almost the entire area from the top end to the bottom end.

Naturally, various arrangements of the frame and the partitioning material relative to the frame can be applied. For example, the frame may be structurally divided into a front half structure primarily made up of the front wall and the front half of the first and second side walls, and a rear half structure primarily made up of the back wall and the rear half of the first and second side walls. In this way, the front half structure and rear half structure can be assembled at the installation site, which contributes to the convenience of installation work.

A booth is a space that can be used by a single user.

Doors can take various forms and are not limited to those shown in the above-mentioned embodiments. For example, the door may be completely opaque, or may be made of mirrored glass that allows the outside to be seen only from the inside. The door may also be constructed primarily from completely transparent materials. The door may also be designed to electrically change its transparency using a liquid crystal panel or the like.

The front wall, back wall, side walls, top wall, and ceiling wall may be made of mesh-like or blind-like materials, as appropriate.

In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.
