Description

The present invention relates to a booth.

Conventionally, booths for office work, meetings, etc. may be set up in offices, exhibition halls, public facilities, etc. (see, for example, Patent Document 1). In particular, in recent years, mobile work utilizing ICT (information and communication technology) such as offices with free addresses and mobile terminals and personal computers has been progressing. Therefore, there are increasing opportunities for one or two people to work or have a meeting using a small space booth at various destinations. Such a booth can also be used as a small office.

When such a booth is installed in a place where ambient sound is loud, high sound insulation is required for the booth. For example, Patent Document 2 discloses a booth in which sound insulation is enhanced by including glass wool in a wall body.

Japanese Unexamined Patent Publication No. 2018-135722 Japanese Unexamined Patent Publication No. 60-92564

By the way, in Patent Document 2, since the sound insulation property is enhanced by including glass wool in the wall body, the sound insulation performance of the wall body cannot be easily adjusted. For example, in the case of a movable booth that can be easily moved by installing casters or the like in the booth, the booth will be moved to various places, and the sound insulation required for the booth depends on the location of the booth. Performance is different. For example, when it is necessary to hear an external announcement sound inside a booth, it is necessary to finely adjust the sound insulation performance so that the announcement sound can be heard while shielding the external noise. In such a case, in order to hear the announcement sound at a constant volume inside the booth, it is necessary to fine-tune the sound insulation performance of the booth according to the distance from the sound source of the announcement sound to the installation location of the booth, for example. .. However, in conventional booths, fine-tuning the sound insulation performance is not considered. By installing a speaker or the like in such a booth, it is possible to play an announcement sound at a constant volume inside, but in such a case, the equipment cost increases. In particular, in the case of a movable booth, it is difficult to make a wired connection, and if the broadcasting equipment such as offices and public facilities does not support wireless broadcasting, it is wireless to the broadcasting equipment such as offices and public facilities. A large capital investment will be required to enable the connection.

That is, in the present embodiment, four columns 3 are installed. These four columns 3 have the same height dimension in the present embodiment. The height dimensions of these columns 3 may be different. Also, the number of columns 3 can be changed.

The side walls 4 are arranged between the columns 3. Since there are four columns 3 in the present embodiment, four side walls 4 are provided in the present embodiment. Of these four side walls 4, the side wall 4 arranged on the front side of the booth 1 is the front side wall 9, the side wall 4 arranged on the right side of the booth 1 is the right side wall 10, and the side wall 4 arranged on the left side of the booth 1 is.

The rear side wall 12 is arranged between two columns 3 arranged on the rear side of the booth 1, and is arranged along one side on the rear side of the rectangular floor portion 2 in a plan view. The rear side wall 12 is erected on the upper surface of the floor portion 2, and the right edge portion is connected to the right column 3 and the left edge is connected to the left column 3. That is, the rear side wall 12 closes between the two columns 3 arranged on the rear side of the booth 1.

The door 5 is pivotally supported by the front side wall 9, and opens and closes the above-mentioned doorway E formed between the front side wall 9 and the support column 3. In the present embodiment, the door 5 is a hinge door rotatably fixed to the front side wall 9 via a hinge. As the door 5, a sliding door or a foldable door can be used instead of the hinge door.

The ceiling wall 6 closes the internal space K from above by being supported from below by the columns 3 and the side walls 4. The ceiling wall 6 includes a ceiling frame 6a and a ceiling panel 6b. The ceiling frame 6a is a frame-shaped member that surrounds the ceiling panel 6b from the horizontal direction and is connected to the peripheral edge of the ceiling panel 6b, and is fixed to the upper ends of the columns 3 and the side walls 4. In the present embodiment, the ceiling panel 6b has a rectangular shape in a plan view, and the ceiling frame 6a surrounding the ceiling panel 6b also has a rectangular shape in a plan view.

FIG. 2 is a cross-sectional view taken along the line AA of FIG. As shown in this figure, the ceiling frame 6a has a larger thickness than the ceiling panel 6b, and the ceiling panel 6b is fixed near the lower end edge. Therefore, the upper end edge of the ceiling frame 6a is arranged higher than the upper surface of the ceiling panel 6b.

The ceiling panel 6b is a plate-shaped member arranged so as to close the area surrounded by the ceiling frame 6a. As shown in FIG. 2, the peripheral edge of the ceiling panel 6b is bent upward to serve as a mounting piece with the ceiling frame 6a. FIG. 3 is a plan view of the ceiling panel 6b. As shown in this figure, the ceiling panel 6b has a rectangular shape in a plan view as described above, and has a large number (s) of sound passage holes 6b1 and two ventilation holes 6b2.

In the present embodiment, the sound passage hole 6b1 has an oval shape having a longitudinal direction in the left-right direction, and is provided so as to penetrate the ceiling panel 6b in the vertical direction. In the present embodiment, six sound passage holes 6b1 are provided and are arranged at equal intervals in the front-rear direction. That is, in the booth 1 of the present embodiment, a plurality of slit-shaped sound passage holes 6b1 long in the left-right direction are arranged in the front-rear direction. For example, the sound passage holes 6b1 are arranged at a pitch twice the dimension in the lateral direction (that is, the front-rear direction of the booth 1).

These sound passage holes 6b1 are openings for passing sound from the external space of the booth 1 of the present embodiment to the internal space K. In the booth 1 of the present embodiment, these sound passage holes 6b1 form a sound passage region R for passing sound from the external space of the booth 1 of the present embodiment to the internal space K. The sound transmission region R may be a region on the ceiling wall 6 where sound can easily pass through the internal space K with respect to other regions of the sound transmission region R, and is not necessarily the region of the present embodiment. It does not have to be formed by through holes. In such a sound-transmitting region R, the sound in the external space easily passes through the internal space K in proportion to the number of open sound-transmitting holes 6b1. That is, when the volume in the external space is constant, the volume in the internal space K changes according to the number of open sound passage holes 6b1.

The ventilation holes 6b2 have a circular shape and are provided so as to penetrate the ceiling panel 6b in the vertical direction. A fan (not shown) is installed in the ceiling panel 6b so as to be housed in the ventilation holes 6b2. By driving such a fan, the air inside the internal space K is discharged to the external space through the ventilation holes 6b2. As described above, in the booth 1 of the present embodiment, the above-mentioned sound passage hole 6b1 is provided separately from the ventilation hole 6b2. Therefore, the number of open sound passage holes 6b1 can be adjusted without affecting the intake / exhaust performance of the booth 1.

Note that FIG. 3 illustrates a ceiling panel 6b provided with two openings, a sound passage hole 6b1 and a ventilation hole 6b2. However, when the booth 1 installs a device (not shown) such as lighting equipment on the ceiling wall 6, the ceiling panel 6b is provided with another opening as needed.

The ceiling wall 6 including the ceiling frame 6a and the ceiling panel 6b is formed of a magnetic material. That is, in the present embodiment, the ceiling panel 6b provided with the sound transmission region R is capable of attracting magnets.

The shielding cover 7 is a member that can be fixed to the upper surface 6b3 of the ceiling panel 6b and adjusts the opening ratio of the sound transmission region R (that is, the number of the open sound passage holes 6b1). 4A and 4B are an overall view of the shielding cover 7, in which FIG. 4A is a perspective view seen from above, FIG. 4B is a perspective view seen from below, and FIG. 4C is B in FIG. 4A. −B sectional view. As shown in these figures, the shielding cover 7 includes a base plate 7a and a protruding frame portion 7b.

The base plate 7a is a rectangular plate member, and has a front and back surfaces wider than the sound transmission region R. The end portion in the longitudinal direction of the base plate 7a is bent toward the surface side, and is used as a gripping piece to be gripped by the operator when moving the shielding cover 7. When the sound passage region R is covered from above, such a base plate 7a blocks the sound passage hole 6b1 to prevent the passage of sound in the sound transmission hole 6b1. As described above, since the front and back surfaces of the base plate 7a are wider than the sound transmission region R, it is possible to simultaneously close all of the plurality of sound transmission holes 6b1 provided in the sound transmission region R.

The protruding frame portion 7b is a portion fixed to the back surface side of the base plate 7a and provided so as to project from the back surface of the base plate 7a, and has a rectangular frame shape when viewed from the normal direction of the back surface of the base plate 7a. .. The protruding frame portion 7b has a shape such that the region surrounded by the protruding frame portion 7b can cover the entire area of the sound transmission region R. Therefore, the protruding frame portion 7b can simultaneously enclose all of the plurality of sound passage holes 6b1 provided in the sound transmission region R.

In the present embodiment, the protruding frame portion 7b is formed by four magnets 7c. Each magnet 7c constitutes each of the four sides of the rectangular protruding frame portion 7b. Such a magnet 7c is attracted to the ceiling panel 6b formed of the magnetic material when the shielding cover 7 is attached to the ceiling panel 6b. That is, in the present embodiment, the shielding cover 7 is fixed to the ceiling wall 6 by a magnetic force. It is not always necessary to form all the magnets of the protruding frame portion 7b. Only a part of the protruding frame portion 7b may be used as a magnet, or a magnet may be provided separately from the protruding frame portion 7b.

Such a protruding frame portion 7b is embedded between the upper surface 6b3 of the ceiling panel 6b and the back surface (lower surface) of the base plate 7a when viewed from the side, and the upper surface 6b3 of the ceiling panel 6b and the back surface of the base plate 7a ( Prevents sound from leaking from the bottom surface). For example, when the base plate 7a is arranged above one sound passage hole 6b1, the sound transmission hole 6b1 is covered by the protruding frame portion 7b, and sound is transmitted from the sound transmission hole 6b1 to the internal space K. It is possible to prevent leakage.

As described above, such a shielding cover 7 is fixed to the upper surface 6b3 of the ceiling panel 6b in the present embodiment. In the present embodiment, the lower surface of the ceiling panel 6b is a wall surface on the K side of the internal space of the ceiling wall 6. That is, in the present embodiment, the shielding cover 7 is fixed to a wall surface different from the wall surface on the internal space K side of the ceiling wall 6.

The covering cloth 8 is a cloth material that covers the lower surface of the ceiling panel 6b from the internal space K side, and is supported by being sandwiched between the ceiling frame 6a and the peripheral edge of the ceiling panel 6b as shown in FIG. ing. If necessary, the covering cloth 8 may be attached to the lower surface of the ceiling panel 6b with an adhesive or the like. Such a covering cloth 8 covers the sound passage hole 6b1 provided in the ceiling panel 6b from below, thereby preventing the user of the internal space K from seeing the sound passage hole 6b1. Further, the covering cloth 8 is very thin as compared with the ceiling panel 6b, and has many fine gaps so that sound and air can pass through. Therefore, the covering cloth 8 prevents the sound passage hole 6b1 from being visually recognized, but does not prevent the sound passing through the sound transmission hole 6b1 from being transmitted to the internal space K. The covering cloth 8 may be arranged so as to cover the ventilation holes 6b2, but may have an opening corresponding to the sound passage holes 6b1.

In the booth 1 of the present embodiment having such a configuration, when the booth 1 is installed, the way of hearing the sound in the internal space K is adjusted by adjusting the position of the shielding cover 7. FIG. 5 is a plan view schematically showing the booth 1 of the present embodiment, in which (a) is a state in which all the sound passage holes 6b1 are closed by the shielding cover 7 (that is, the opening ratio of the sound transmission region R is 0%), (b) indicates a state in which half of the sound passage holes 6b1 are blocked by the shielding cover 7 (that is, a state in which the opening ratio of the sound transmission region R is 50%), and (c) Indicates a state in which all the sound passage holes 6b1 are not blocked by the shielding cover 7 (that is, a state in which the opening ratio of the sound transmission region R is 100%).

As shown in FIG. 5A, when the opening ratio of the sound passage region R is 0%, all the sound passage holes 6b1 are closed, so that the outermost space among the three states shown in FIG. Sound becomes difficult to hear in the internal space K. On the other hand, as shown in FIG. 5 (c), when the opening ratio of the sound transmitting region R is 100%, all the sound transmitting holes 6b1 are opened, and therefore, among the three states shown in FIG. The sound in the outer space is most easily heard in the inner space K. Further, as shown in FIG. 5 (b), when the open ratio of the sound transmission region R is 50%, the volume is intermediate between the state shown in FIG. 5 (a) and the state shown in FIG. 5 (c). It is possible to hear the sound of the external space in the internal space K.

For example, when a plurality of booths 1 are arranged in a direction away from the speaker in the external space, the opening ratio of the sound transmission area R in the booth 1 closest to the speaker is minimized, and the sound transmission area increases as the distance from the speaker increases. By gradually increasing the opening ratio of R, it becomes possible to hear the sound from the speaker at substantially the same volume in the internal space K of all booths 1.

In the booth 1 of the present embodiment as described above, a sound transmission region R for passing sound from the external space to the internal space K is provided in a part of the partition wall, and the sound transmission region R is fixed to the partition wall so as to be covered. It is provided with a shielding cover 7 that makes it possible and adjusts the opening ratio of the sound transmission region R. According to the booth 1 of the present embodiment as described above, the volume passing through the partition wall can be easily adjusted by changing the fixed position of the shielding cover 7 to adjust the opening ratio of the sound transmission region R. The sound insulation performance of the booth 1 can be easily adjusted.

Further, in the booth 1 of the present embodiment, the sound passage region R is formed by a plurality of sound passage holes 6b1 penetrating the partition wall. According to the booth 1 of the present embodiment as described above, the opening ratio of the sound transmission region R can be easily grasped by the number of sound transmission holes 6b1 covered by the shielding cover 7. Therefore, for example, when a plurality of booths 1 are arranged at different distances from the sound source in the external space, the volume in the plurality of booths 1 can be easily made constant.

Further, in the booth 1 of the present embodiment, a ceiling wall 6 that closes the internal space K from above is provided as a partition wall, and a sound transmission region R is formed in the ceiling wall 6. According to the booth 1 of the present embodiment as described above, the sound transmission region R is formed on the ceiling wall 6. Since the booth 1 for performing work or the like in the internal space K has a user inside, the height of the ceiling wall 6 is higher than the line of sight of a person passing through the external space. Therefore, by providing the sound-transmitting area R on the ceiling wall 6, the sound-transmitting area R can be made difficult to be visually recognized by a person in the external space, and the sound-transmitting area R affects the design of the booth 1. Can be prevented.

Moreover, in public facilities and the like, speakers are often provided on the ceiling. Therefore, by providing the sound passage region R on the ceiling wall 6, the sound from the speaker can enter the internal space K while preventing the noise from entering the internal space K of the booth 1.

Further, in the booth 1 of the present embodiment, the ceiling wall 6 surrounds the plate-shaped ceiling panel 6b arranged with the front and back surfaces facing in the vertical direction and the ceiling panel 6b from the horizontal direction on the peripheral edge of the ceiling panel 6b. A configuration is adopted in which the ceiling frame 6a is connected and the upper end edge is higher than the upper surface of the ceiling panel 6b, and the sound transmission region R is formed in the ceiling panel 6b.

According to the booth 1 of the present embodiment as described above, the sound transmission region R is formed in the ceiling panel 6b surrounded by the ceiling frame 6a and arranged at a position lower than the upper end edge of the ceiling frame 6a. Therefore, the sound transmission area R is formed at a position hidden by the ceiling frame 6a, the sound transmission area R can be made difficult to be seen by a person in the external space, and the sound transmission area R affects the design of the booth 1. It can be prevented from giving.

Further, the booth 1 of the present embodiment is provided with a covering cloth 8 that allows sound to pass through and covers the sound transmission region R from the internal space K. According to the booth 1 of the present embodiment as described above, the sound transmission region R is hidden from the internal space K side by the covering cloth 8 through which sound can pass. Therefore, it is possible to prevent the sound transmission region R from being visually recognized from the internal space K while suppressing the attenuation of the sound passing through the sound transmission region R. Therefore, according to the booth 1 of the present embodiment, it is possible to prevent the sound transmission region R from affecting the design of the internal space K.

Further, in the booth 1 of the present embodiment, a configuration in which the covering cloth 8 is formed of a cloth material is adopted. According to the booth 1 of the present embodiment as described above, the covering cloth 8 is formed of a material that is easy to change in shape and is lightweight. Therefore, it is possible to reduce the work load when the covering cloth 8 is installed.

Further, in the booth 1 of the present embodiment, the ceiling wall 6 is formed of a magnetic material, and the shielding cover 7 has a magnet 7c. According to the booth 1 of the present embodiment as described above, the shielding cover 7 can be fixed to the ceiling wall 6 by a magnetic force. Therefore, the position of the shielding cover 7 with respect to the ceiling wall 6 can be easily changed.

The outer panel 9b is a panel member that is arranged on the outside (external space side) of the booth 1A with respect to the side wall frame 9a and covers the entire side wall frame 9a from the outside. The outer panel 9b is arranged to face the inner panel 9c arranged inside the booth 1A (internal space K side) with respect to the side wall frame 9a. Such an outer panel 9b is provided with a plurality of (three in the present embodiment) openings 9d arranged at equal intervals in the vertical direction.

The inner panel 9c is a panel member that is arranged inside the booth 1A (internal space K side) with respect to the side wall frame 9a and covers the entire side wall frame 9a from the inside. The inner panel 9c is provided with a plurality of (three in the present embodiment) sound transmission regions R arranged at equal intervals in the vertical direction. These sound transmission regions R are formed at the same height as the opening 9d, and are provided at positions overlapping the opening 9d when viewed from the horizontal direction. It should be noted that each of these sound transmission regions R is formed by a plurality of sound transmission holes 9e, as in the first embodiment. In this embodiment, the plurality of sound passage holes 9e forming one sound transmission region R are arranged at equal intervals in the vertical direction.

Such an inner panel 9c is formed of a magnetic material. Further, in the booth 1A of the present embodiment, the shielding cover 7 is fixed to the surface of the inner panel 9c facing the outside of the booth 1A. The shielding cover 7 is provided for each of the sound transmission regions R. The surface of the inner panel 9c facing the inside of the booth 1A is the wall surface of the front side wall 9 on the internal space K side. That is, also in this embodiment, the shielding cover 7 is fixed to a wall surface different from the wall surface on the K side of the internal space of the partition wall.

Further, in the booth 1A of the present embodiment, the covering cloth 8 covers the inner surface of the inner panel 9c. That is, also in the present embodiment, the covering cloth 8 covers the sound transmitting area R from the internal space K side, and prevents the user of the internal space K from visually recognizing the sound transmitting area R. Such a covering cloth 8 is supported by being sandwiched between the side wall frame 9a and the inner panel 9c.
