Description

[Technical field]

[0001] The present invention relates to a booth. [Background technology]

[0002] Conventionally, booths for carrying out work and the like have been installed in offices, exhibition halls, public facilities, and the like (for example, see Patent Document 1). In particular, in recent years, the trend toward free address systems in offices and mobile work utilizing ICT (information and communication technology) such as mobile terminals and personal computers has progressed. As a result, there are an increasing number of opportunities to carry out work and the like in small booths at various destinations.

[0003] Thus, in recent years, as the demand for booths has increased, there has been a demand for booth doors that are more compact. For example, in a booth with a hinged door as shown in Patent Document 2, a space is required on the outside of the door so that the door can open, but if a horizontal sliding door is used instead of a hinged door, the space on the outside of the door is not required, but a space is required for the door to enter when it is opened, and for this reason, an entry space of the same width as the door is usually required next to the door.

[0004] In contrast, the booth described in the above-mentioned Patent Document 1 uses a swiveling sliding door, which means that it does not require a large space on the outside or sides. When using such a swiveling sliding door, if rails are provided on the floor inside the booth, there is a risk that objects may get caught in the rails or that booth users may trip over the rails. For this reason, in recent years, suspended sliding doors with rails on the upper side have been adopted. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-008783 [Patent Document 2] JP 2020-204231 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in booths that use suspended sliding doors, the weight of the door is supported by rails attached to the ceiling, so the rails installed on the ceiling must be large and rigid enough to support the weight of the door. However, in addition to the rails, it is necessary to provide booth equipment such as lighting, fire extinguishers, and speakers on the ceiling of the booth. On the other hand, as mentioned above, there is also a demand for making the booth more compact, and when a large rail supporting a suspended sliding door is provided on the ceiling of a compact booth, it is necessary to position other booth equipment in an appropriate position, and there is room for improvement in this regard. In particular, there is a demand for arranging the vents so that air can be ventilated more efficiently when the booth is made compact.

[0007] Therefore, the present invention has been made in consideration of the above circumstances, and provides a booth that can improve ventilation efficiency and ease of use by arranging at least a fire extinguishing equipment and an air vent in an appropriate position on the ceiling surface. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention employs the following means. In other words, the booth of the present invention comprises a ceiling surface, a sliding door that separates an internal space from an external space and is arranged to be openable and closable, and a guide rail that is arranged on the ceiling surface and supports the sliding door so that it can be opened and closed, the guide rail being arranged on one side of the width direction perpendicular to the front-to-back direction of the booth of the ceiling surface, and the ceiling surface is equipped with a fire outlet arranged in the center of the width direction, and an air vent arranged on the opposite side of the guide rail in the width direction, sandwiching the fire outlet therebetween.

[0009] In the booth according to the present invention, the fire extinguishing outlet and the ventilation opening can be installed without interfering with the guide rail. In other words, the fire extinguishing outlet can be installed in the center of the ceiling surface, resulting in an arrangement that can fully demonstrate the fire detection and water spraying efficiency without reducing it. In addition, since the ventilation opening is arranged on the opposite side of the guide rail in the width direction, a large ventilation opening can be used without interfering with the guide rail. In this way, in the present invention, at least the fire extinguishing equipment and the ventilation openings can be arranged in appropriate positions on the ceiling surface of the booth, thereby improving ventilation efficiency and ease of use.

[0010] In addition, the booth of the present invention may be characterized in that lighting is arranged on the ceiling surface on the opposite side of the entrance / exit opening between the internal space and the external space, across the fire exit in the front-to-back direction.

[0011] In a booth constructed in this way, lighting can be placed in the space between the rear end of the ceiling and the fire exit, allowing lighting to be provided so that it shines on the back side of the entrance opening (the side opposite the entrance opening in the front-to-back direction), which is an easy-to-use working position for users in the booth.

[0012] In addition, in the booth of the present invention, the air vent may be a first air vent, a second air vent is provided in a floor portion of the internal space, and the second air vent is arranged on the opposite side of the first air vent in the width direction, across the fire extinguisher, when viewed from above.

[0013] In the booth configured in this way, for example, the first vent can be used as an air supply port and the second vent can be used as an exhaust port, or the first vent can be used as an exhaust port and the second vent can be used as an air supply port. As a result, the air supply port and the exhaust port are arranged diagonally, so that air in the interior space of the booth flows from the second vent in the floor toward the first vent arranged on the opposite side of the fire extinguisher in the width direction when viewed from above, or in the opposite direction. Therefore, the entire interior space can be efficiently ventilated with a sufficient amount of ventilation.

[0014] In addition, in the booth of the present invention, the sliding door may be curved in an arc shape centered on a rotation axis located in the internal space and be capable of rotating around the rotation axis, and a speaker may be arranged on the ceiling surface between the fire exit and the guide rail, and the speaker may be arranged in an opening that is circular in a plan view formed on the ceiling surface.

[0015] In a booth configured in this way, the guide rail for pivoting the sliding door is arranged in a state where it bulges outward in the width direction in the center of the booth in the front-rear direction. The space between the fire extinguisher and the guide rail on the ceiling surface is a restricted space that is inside the arc-shaped space bulging outward in the width direction of the guide rail. Therefore, a circular opening in a plan view for mounting a speaker can be efficiently arranged in this space. In this way, in addition to the fire extinguisher and the vent, the speaker can also be arranged in an appropriate position without interfering with the guide rail. Effect of the Invention

[0016] According to the booth of the present invention, by arranging at least the fire extinguishing equipment and the ventilation openings in appropriate positions on the ceiling surface, it is possible to improve the efficiency of ventilation and improve usability.

The underside of the floor section 2 is provided with a plurality of casters and a plurality of height-adjustable adjusters at appropriate positions. The casters are provided so as to be able to contact the floor surface F, and by rolling, the entire booth 1 can be easily moved. Furthermore, when installing the booth 1, by contacting the adjusters with the floor surface F, the casters are separated from the floor surface F, and movement of the booth 1 is restricted.

[0023] A part of the front end of the floor section 2 has an entrance / exit section 23 of the booth 1 below the entrance / exit opening E (see FIG. 4). The entrance / exit section 23 has an arc shape that follows the shape of the door surface of the sliding door 4, which has an arc surface, and forms a convex curved surface that is convex outward.

[0024] As shown in FIG. 1, the outer wall portion 3 includes a support 31 , a side wall 32 , and a ceiling wall 33 .

[0025] The pillars 31 are column members erected on the floor portion 2. The pillars 31 are disposed at each of the four corners of the floor portion 2, which is rectangular in plan view. These four pillars 31 have the same height. However, the heights of these pillars 31 may differ. The number of pillars 31 can also be changed.

[0026] The side walls 32 are disposed between the adjacent columns 31. The side walls 32 have a front wall portion 32A disposed at the front side of the booth 1, a right wall portion 32B disposed at the right side of the booth 1, a left wall portion 32C disposed at the left side of the booth 1, and a rear wall portion 32D disposed at the rear side of the booth 1.

[0027] Between a pair of pillars 31, 31 provided on the front side of the outer wall 3, there are a front wall 32A fixed to the left pillar 31, and an entrance opening E forming an entrance / exit for users, where a sliding door 4 is arranged so as to be able to open and close between the front wall 32A and the right pillar 31. The front wall 32A is erected on the floor surface 2b on the upper surface of the floor 2, and the lower part of the front wall 32A and the lower part of the right pillar 31 are connected by the entrance / exit part 23 of the floor 2. The right wall portion 32B, the left wall portion 32C, and the rear wall portion 32D are erected on the floor surface 2b of the floor portion 2, and both ends thereof are connected to the pillars 31.

[0028] As shown in FIG. 1, a desk 70 consisting of a tabletop is provided at the rear of the internal space K1 surrounded by the front wall 32A, the right wall 32B, the left wall 32C, and the rear wall 32D (see FIG. 4). In other words, the desk 70 is located opposite the entrance opening E across a chair (not shown). The desk 70 is attached in contact with the inner wall surface 32a of the rear wall 32D and is provided so as to extend forward from the rear wall 32D. The right edge of the desk 70 is fixed to the right wall 32B, and the left edge is fixed to the left wall 32C. The height of the desk 70 is set to a height that can be used by a user seated in a chair (not shown).

[0029] The ceiling wall 33 is supported from below by the columns 31 and the side walls 32, thereby closing off the internal space K1 from above. The ceiling wall 33 includes a ceiling frame (not shown) and a ceiling panel 33A. The ceiling frame is a frame-like member that surrounds the ceiling panel 33A in the horizontal direction and is connected to the periphery of the ceiling panel 33A, and is fixed to the upper ends of the columns 31 and the side walls 32. The ceiling panel 33A is a plate-like member that is supported by the ceiling frame and is arranged inside the ceiling frame in a plan view. In this embodiment, an equipment housing section 76 for housing part of the booth equipment 7 is provided above the ceiling panel 33A.

[0030] As shown in FIG. 1, the sliding door 4 is a hanging door that is suspended and supported by an upper guide mechanism 5 so as to be movable to open and close. The sliding door 4 is a door body curved in an arc shape centered on a pivot axis C (see Figs. 3 and 4), and is capable of opening and closing the entrance opening E by an upper guide mechanism 5. The sliding door 4 includes a glass panel 41, an upper edge frame 42, a lower edge frame 43, and a side edge frame 44 (see Fig. 4). The sliding door 4 pivots about the pivot axis C and enters the internal space K1 in an open state.

[0031] The glass panel 41 is a panel body made of glass and has a rectangular shape when viewed from the front and rear. Although the glass panel 41 is used to ensure the light transmittance of the sliding door 4, a panel body made of another material can be used if light transmittance is not required.

[0032] The upper edge frame 42 is a frame member joined to the upper edge of the glass panel 41. The lower edge frame 43 is a frame member joined to the lower edge of the glass panel 41. The side edge frames 44 are frame members joined to the right and left edges of the glass panel 41, and are fixed to the ends of the upper edge frame 42 and the lower edge frame 43 by bolts (not shown). Two such side edge frames 44 are provided in this embodiment. The upper edge frame 42, the lower edge frame 43, and the side edge frames 44 are formed of, for example, an aluminum alloy.

[0033] The sliding door 4 has a curved shape such that the center part bulges toward the external space K2 in a plan view. When the sliding door 4 is placed in a closed position that closes the entrance opening E, the center part of the sliding door 4 protrudes toward the external space K2 from the outer wall surface of the front wall part 32A in a plan view. In other words, as shown in FIG. 2, when the sliding door 4 is closed, the center part of the sliding door 4 protrudes forward from the outer wall surface of the front wall part 32A. Such a sliding door 4 is capable of pivoting about a pivot axis C along the vertical direction so as to open and close the entrance opening E.

[0034] As shown in FIG. 1, the upper guide mechanism 5 is supported by being suspended from the front side of the ceiling wall 33, and is disposed above the entrance opening E provided in the front wall portion 32A. The upper guide mechanism 5 is provided on the ceiling surface 33a and includes a guide rail 51 that suspends and supports the sliding door 4 so that the sliding door 4 can be opened and closed in the circumferential direction around the pivot axis C shown in FIG. 3 along the vertical direction. That is, the upper edge frame 42 of the sliding door 4 is supported by the upper guide mechanism 5. For example, the upper guide mechanism 5 includes a linear motor (not shown) or the like. When the upper guide mechanism 5 includes a linear motor in this manner, the sliding door 4 moves automatically.

[0035] Next, the booth equipment 7 provided on the ceiling surface 33a of the ceiling wall 33 and the floor surface 2b of the floor portion 2 will be specifically described. As shown in Figures 2 and 3, on the ceiling surface 33a of the ceiling wall 33, the guide rail 51 of the upper guide mechanism 5 described above, a fire outlet 71, an air outlet 72 (first air outlet), a speaker 73, and a light 74 are provided.

[0036] A portion of the guide rail 51 located in the internal space K1 is disposed on one side (left side) in the width direction of the ceiling surface 33a.

[0037] The fire extinguisher 71 is disposed at the center of the ceiling surface 33a and at the center in the width direction. The fire extinguisher 71 is provided in a fire extinguishing device 710. The fire extinguishing device 710 includes an extinguishant container 711 filled with an extinguishant, a heat detection sensor 712 exposed to the internal space K1 on the lower surface of the extinguishant container 711, and the fire extinguisher 71 having a downward discharge type extinguisher nozzle that discharges the extinguishant in the extinguishant container 711 downward when the heat detection sensor 712 detects heat. The planar shape of the extinguishant container 711 is set according to the amount of extinguishant based on conditions such as the size of the internal space K1 of the booth 1. In the fire extinguisher 710 of this embodiment, the fire outlet 71 and the extinguishant container 711 are integrally provided, but the fire extinguishant container 711 may be disposed at a location away from the fire outlet 71.

[0038] The ventilation opening 72 is an opening that communicates the internal space K1 with the external space K2, and is disposed in the first space S1 of the ceiling surface 33a on the opposite side of the guide rail 51 across the fire extinguishing opening 71 in the width direction. In this embodiment, two ventilation openings 72A and 72B are disposed in the front-rear direction. The ventilation openings 72 are designated by the reference symbol 72A on the near side (the entrance / exit opening E side) and the reference symbol 72B on the far side. Note that the ventilation opening 72 may be provided with an exhaust fan when forced exhaust is performed from the ventilation opening 72, and may be provided with an air supply fan when forced air is supplied from the ventilation opening 72.

[0039] 4 is a plan view of floor surface 2b, and two vents 72A, 72B arranged on ceiling surface 33a are indicated by two-dot chain lines. As shown in FIG. 4, vent 72B, which is located at the back of the two vents 72, is arranged in a position overlapping with the top of desk 70 in plan view.

[0040] In the above embodiment, the ceiling surface 33a is provided with a plurality of (two) vents 72A, 72B, but it is also possible to adopt a configuration in which, for example, one vent extending long in the front-to-rear direction is disposed in the first space S1 of the ceiling surface 33a as a modified example of the vent 72. Even in the case of this modified example, it is preferable that at least a portion of the rear side of the vent long in the front-to-rear direction is disposed so as to overlap above the desk 70 in a plan view.

[0041] The speaker 73 is disposed in a second space S2 between the fire exit 71 and the guide rail 51. The second space S2 is a restricted area that is on the inside of a circular arc that bulges outward in the width direction of the guide rail 51. The speaker 73 is provided in an opening that is circular in plan view and formed in the ceiling surface 33a.

[0042] The lighting 74 is disposed in the third space S3 of the ceiling surface 33a on the opposite side of the entrance opening E between the internal space K1 and the external space K2, with the fire exit 71 sandwiched between them in the front-to-rear direction.

[0043] As shown in Fig. 4, a second air vent 75 is provided on the floor surface 2b of the floor portion 2 of the internal space K1 to send air into the internal space K1 or send air from the internal space K1 to the external space K2. The second air vent 75 is disposed in the center in the front-rear direction and is disposed on the opposite side of the air vent 72 in the width direction across the fire outlet 71 in top view. Note that the second air vent 75 may be provided with an air supply fan when forced air is sent from the second air vent 75, and the second air vent 75 may be provided with an exhaust fan when forced exhaust is sent from the second air vent 75.

[0044] In the booth 1 configured in this manner, the fire extinguisher 71 and the ventilation opening 72 can be provided without interfering with the guide rail 51. That is, the fire extinguisher 71 can be installed in the center of the ceiling surface 33a, resulting in an arrangement that can fully demonstrate fire detection and water spraying efficiency without reducing it. In addition, since the ventilation opening 72 is disposed on the opposite side to the guide rail 51 in the width direction, a large ventilation opening 72 can be used without interfering with the guide rail 51. In this manner, in this embodiment, at least the fire outlet 71 and the ventilation opening 72 can be disposed at appropriate positions on the ceiling surface 33a of the booth 1, improving ventilation efficiency and ease of use.

[0045] In addition, in the booth 1 according to this embodiment, the guide rail 51 for pivoting the sliding door 4 is arranged in a state in which it bulges in an arc shape so as to be convex outward in the width direction in the center part in the front-rear direction of the booth 1. The space between the fire outlet 71 and the guide rail 51 on the ceiling surface 33a forms a restricted second space S2 that is the inside of the arc shape bulging outward in the width direction of the guide rail 51. Therefore, in the second space S2, an opening that is circular in plan view can be efficiently arranged for mounting the speaker 73. Thus, in this embodiment, in addition to the fire outlet 71 and the ventilation opening 72, the speaker 73 can also be arranged in an appropriate position without interfering with the guide rail 51.

[0046] Furthermore, in the booth 1 according to this embodiment, the lighting 74 can be arranged by utilizing the third space S3 between the rear end of the ceiling surface 33a and the fire exit 71. This allows the lighting 74 to be provided so that light falls on the back side of the entrance / exit opening E (the side opposite the entrance / exit opening E in the front-to-rear direction), which is easily used as a work position for users in the booth 1.

[0047] Furthermore, in this embodiment, two vents 72A, 72B are arranged in the front-rear direction, and one of them (the vent with reference symbol 72B) is arranged at a position overlapping above the desk 70 in a plan view, so that air in the internal space K1 of the booth 1 flows toward the vent 72B located above the desk 70, allowing ventilation with a sufficient volume around the mouth of a user working at the desk 70. For example, if a vent is arranged in front of a user working at the desk 70 (on the side of the entrance / exit opening E), the back of the user is ventilated, which reduces the volume of ventilation around the user's mouth. This can be improved.

[0048] Furthermore, since the ventilation opening 72 extends long in the front-to-rear direction, even when at least a portion of the ventilation opening 72 overlaps above the desk 70 in a plan view, the air in the internal space K1 of the booth 1 flows toward the ventilation opening 72 located above the desk 70, so that a sufficient amount of ventilation can be provided to the mouths of users working at the desk 70.

[0049] In addition, in the booth 1 according to this embodiment, the second vent 75 provided in the floor surface 2b of the floor portion 2 and the vent 72 (first vent) provided in the ceiling surface 33a are arranged diagonally, so that the air in the internal space K1 of the booth 1 flows from the second vent 75 in the floor portion 2 toward the vent 72 arranged on the opposite side across the fire outlet 71 in the width direction when viewed from above, or in the opposite direction. Therefore, the entire internal space K1 can be efficiently ventilated with a sufficient amount of ventilation.

[0050] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0051] For example, in the embodiment described above, the ceiling surface 33a is configured to include the speaker 73 and the lighting 74 in addition to the guide rail 51, the fire extinguisher 71, and the ventilation hole 72, but the speaker 73 and the lighting 74 may be omitted. Also, in the embodiment, the speaker 73 is disposed in the second space S2 and the lighting 74 is disposed in the third space S3, but they may be disposed in other positions as long as they do not interfere with the guide rail 51. Furthermore, it is of course possible to arrange other booth equipment not exemplified in the above-mentioned embodiment on the ceiling surface 33a in an area where it does not interfere with the guide rail 51.

[0052] In this embodiment, the vent 72 provided in the ceiling surface 33a is used for exhaust and the second vent 75 in the floor surface is used for supplying air, but the present invention is not limited to this. For example, the vent in the ceiling surface 33a may be used as an air supply port and the second vent in the floor surface may be used as an exhaust port, or the ceiling surface 33a may have the functions of both an exhaust vent and an air supply vent.

[0053] In addition, in this embodiment, the sliding door supported by the guide rail 51 is of a pivoting type, but the sliding door is not limited to the pivoting type. In short, it is sufficient that the guide rail provided on the ceiling surface 33a is disposed on one side of the width direction of the ceiling surface perpendicular to the front-rear direction of the booth, and for example, the guide mechanism can be applied to a sliding door that can be opened and closed linearly in the width direction.

[0054] In the embodiment, the booth 1 in which only one user can enter the internal space K1 has been described. However, the present invention is not limited to this, and may be applied to a booth in which multiple people can enter the internal space K1.

[0055] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
