Description

The present invention relates to a booth used for office work, meetings, etc.

Conventionally, booths that can suppress the intrusion of outside noise and human voices and block views from the outside to increase concentration in the internal space have been known (see, for example, Patent Document 1).

However, this type of booth is generally assembled at the location where it is to be installed, and moving it is difficult. For this reason, booths have been developed that are equipped with casters and adjusters on the bottom, and after moving it using the casters, the entire booth can be lifted with the adjusters to adjust the installation height, and the caster function can be disabled to leave the booth stationary in the desired position.

However, with only this, there is a concern that the entire booth may shift in the event of an earthquake or the application of unexpected external forces. For this reason, it has been considered to further secure the base of the booth to the building floor using fixing brackets or anchor bolts, etc., but conventional wisdom would dictate that this work be carried out from the outside of the booth. As a result, the fixing brackets etc. would protrude to the outside, marring the appearance and obstructing passage, among other problems.

Furthermore, when placing this type of booth in a corner of a building, performing the fixing work from outside the booth can result in the following problems. That is, when placing such booths side by side with the backs of the booths butted up against the wall of the building, it is extremely difficult to perform the fixing work described above in a recessed position.

Japanese Unexamined Patent Publication No. 48-88752

The present invention aims to provide a booth that can simultaneously solve the various problems described above.

The booth of the invention described in claim 1 is a booth which has a base plate that covers the underside of the internal space, and is provided with casters on the underside of the base plate, and adjusters that lift the base plate relative to the building floor while disabling the rolling function of the casters. The base plate has an opening that connects the internal space to the external space, and a fixing device for fixing the base plate to the building floor is arranged near the opening. The fixing device is for anchoring the base plate to the building floor in a state in which the base plate is raised by adjusting the adjuster until the rolling function of the casters is disabled, and the fixing device is configured so that the attachment position of the fixing device relative to the structural material of the base plate can be adjusted in the vertical direction , thereby allowing the base plate to be closely attached to the building floor without the use of spacers .

The invention of claim 2 relates to a booth according to claim 1, in which the fixing device is supported by the structural material of the base that supports the casters and the adjuster.

The invention of claim 3 relates to a booth according to claim 1 or 2, in which the fixture is disposed inside the outer edge of the base plate in a plan view, and the opening is provided at a position where the fixture can be accessed from the internal space.

The present invention provides a booth that can be moved after assembly and can be set up in a desired position without causing problems such as the fasteners protruding beyond the outer edge of the booth.

One embodiment of the present invention will be described below with reference to Figures 1 to 18.

This embodiment shows the application of the present invention to a two-person booth B.

As shown in Figures 1 to 4, this booth B is equipped with a base 1 that covers the bottom side of the internal space IS, surrounding walls (front wall 2, side wall 3, back wall 4) that surround the periphery of the internal space IS, and a ceiling 5 that covers the top side of the internal space IS. A table 6 is placed in the center of the internal space IS, and chairs 7 are provided on either side of the table 6.

As shown in Figures 4, 5 and 9, the base plate 1 comprises a base body 11 made of, for example, sheet metal that constitutes the outer shell, reinforcing members (horizontal reinforcing members 12 extending left and right, horizontal reinforcing members 13 extending front and rear, and vertical reinforcing members 14) rigidly connected to the inner surface of the base body 11, a floor plate 15 placed on the base body 11 reinforced by the reinforcing members 12 to 14, and a mat 16 laid on the floor plate 15. The base plate 1 of this embodiment can be transported separately into a left bottom unit L, a middle bottom unit M, and a right bottom unit N, and when installed, the base bodies 11 of the bottom units L, M, and N and the horizontal reinforcing members 12 extending left and right are connected to each other via brackets 10 or the like to be integrated. That is, the base body 11 is divided into a base body 11 (L) belonging to the left bottom unit L, a base body 11 (M) belonging to the middle bottom unit M, and a base body 11 (N) belonging to the right bottom unit N. The floor plate 15 is divided into one floor plate 15 (L) placed on the left bottom unit L, two floor plates 15 (M) placed roughly on the middle bottom unit M, and one floor plate 15 (N) placed on the right bottom unit N. In the figure, 17 is a caster for moving the base plate 1 along the building floor F, 18 is an adjuster for adjusting the height position of the four corners of the base plate 1 after movement, and 19 is a fixing device for fixing the base plate 1 to the building floor F after the height adjustment is completed. This fixing device 19 is for fixing the base plate 1 to the building floor F using an anchor bolt T, as described later.

The front wall 2, which is a peripheral wall, closes the front of the internal space IS, and as shown in Figures 1, 2, 7 and 9, is equipped with a left fixed panel 21 having a width dimension corresponding to the left floor unit L described above, a door panel 22 having a width dimension corresponding to the middle floor unit M, and a right fixed panel 23 having a width dimension corresponding to the right floor unit N. The left and right fixed panels 21, 23 are made by fitting transparent plates 21b, 23b such as glass into frames 21a, 23a. The door panel 22 is equipped with a door edge frame 22b hinged to the fixed frame 22a, and a transparent plate 22c fitted into this door edge frame 22b. In the figures, 22d is a hinge and 22e is a handle.

As shown in Figs. 6 to 8, the side wall 3, which is the peripheral wall, comprises an outer plate 31, a sound-absorbing material 34 attached to the inner surface of the outer plate 31, and an interior sound-absorbing panel 35 arranged on the inner surface of the sound-absorbing material 34. The outer plate 31 has an area capable of blocking the entire side surface of the internal space IS. The outer plate 31 is made of, for example, sheet metal, and on its inner surface, a number of reinforcing members 32 extending in the front-rear direction and, for example, two reinforcing members 33 extending in the up-down direction are rigidly connected by welding or the like in a cross-like state and reinforced. The aforementioned sound-absorbing material 34 is arranged in the lattice-like space formed by these reinforcing members 32 and 33. The sound-absorbing material 34 has an uneven surface on the surface facing the sound-absorbing panel 35, and is made of a cushioning material such as slab urethane. The interior sound-absorbing panel 35 is, for example, made of a wooden plate member 36, a urethane 37 attached to one side of the plate member 36, and a non-flammable upholstery 38 that encases the urethane 37. The non-flammable upholstery 38 and the urethane material 37 are bonded together with hot melt. The sound-absorbing panel 35 is divided into an upper sound-absorbing panel 35(U) and a lower sound-absorbing panel 35(D). The lower sound-absorbing panel 35(D) is smaller in vertical dimension than the upper sound-absorbing panel 35(U), but has the same structure as the upper sound-absorbing panel 35(U). In the figure, 34a is the surface of the sound-absorbing material 34 that has projections and recesses. AG is an air gap formed between the surface 34a of the sound-absorbing material 34 that has projections and recesses and the plate member 36 of the sound-absorbing panel 35. Reference numeral 36a denotes a recess formed on the surface of plate-shaped member 36 opposite the surface to which urethane 37 is attached, for increasing the volume of the air gap AG. Note that plate-shaped member 36 may be a relatively thick (e.g., 15 to 17 mm) plate without recess 36a. In this case, air gap AG is formed only between surface 34a of sound-absorbing material 34, which has projections and recesses, and the portion where sound-absorbing material 34 contacts plate-shaped member 36.

As shown in Figures 4 and 7, the rear wall 4, which is a peripheral wall, comprises a left fixing panel 41 arranged between a support pillar (not shown) that supports the rear edge of the left side wall 3 and an intermediate support pillar 42, and a right fixing panel 43 arranged between the intermediate support pillar 42 and a support pillar (not shown) that supports the rear edge of the right side wall 3.

As shown in Figures 4, 9 to 11 and 14, the ceiling 5 comprises a top plate body 51 made of, for example, sheet metal that constitutes the outer shell, reinforcing members (horizontal reinforcing members 52 extending left and right, horizontal reinforcing members 53 extending front and rear, and vertical reinforcing members 54) rigidly connected to the inner surface of the top plate body 51, and an interior ceiling panel 56 disposed under the top plate body 51 reinforced by the reinforcing members 52, 53, and 54. The ceiling 5 in this embodiment can be transported separately into a left ceiling unit P, a middle ceiling unit Q, and a right ceiling unit R, and when assembled, the ceiling bodies 51 of the ceiling units P, Q, and R and the horizontal reinforcing members 52 extending left and right are connected to each other via brackets 55 or the like to be integrated. That is, the tabletop body 51 is divided into a tabletop body 51 (P) belonging to the left ceiling unit P, a tabletop body 51 (Q) belonging to the middle ceiling unit Q, and a tabletop body 51 (R) belonging to the right ceiling unit R. The ceiling panel 56 is also divided into a ceiling panel 56 (P) disposed under the left ceiling unit P, a ceiling panel 56 (Q) disposed under the middle ceiling unit Q, and a ceiling panel 56 (R) disposed under the right ceiling unit R. The tabletop bodies 51 (P), 51 (R) of the left and right ceiling units P, R are each provided with, for example, three ventilation fans 57, and the tabletop body 51 (Q) of the middle ceiling unit Q is equipped with a sprinkler 58. The sprinkler 58 is for spraying fire-extinguishing water into the internal space IS when a fire is detected, and its spray nozzle 58a faces the internal space IS through an opening 56a provided in the middle ceiling panel 56 (Q). The middle ceiling panel 56 (Q) is also equipped with downlights 59 to illuminate the interior space IS.

As shown in Figures 1 and 4, the table 6 arranged in the internal space IS is equipped with a top plate 61 whose base end is supported by the intermediate support 42 of the back wall 4, and a leg support 62 that supports the vicinity of the tip of the top plate 61, and a leg base 63 supported by the base plate 1 is provided at the lower end of the leg support 62.

As shown in Figures 1, 4 and 12, the chairs 7 arranged on both sides of the table 6 each include a chair base 71 placed on the mat 16 of the base 1, a box-shaped chair body 72 with an open bottom that is placed on the chair base 71, and a backrest 79 erected at the back of the chair body 72.

As shown in FIG. 5, each chair base 71 is a frame-shaped combination of frame materials in a square shape, and the inner space 71S of each chair base 71 is connected to the slit-shaped ventilation openings 11a formed in the base body 11(L) and 11(N) via the notches 16a formed at both the left and right ends of the mat 16 and the notches 15a formed in the floorboard 15, as shown in FIGS. 4, 12, and 13, so that air AI from the external space OS is introduced into the inner space 71S of each chair base 71 through these ventilation openings 11a and the notches 15a and 16a. In addition, a communication opening 71b is formed in the front frame material 71a of the chair base 71, which connects the inner space 71S of the chair base 71 to the internal space IS of the booth B.

As shown in FIG. 12, the chair body 72 includes a front panel 73 facing the internal space IS of the booth B, a rear panel 74 located under the backrest 79, a seat support plate 75 installed between the upper ends of the front panel 73 and the rear panel 74, side panels 76 covering the side ends of the front panel 73 and the rear panel 74, and an intermediate panel 77 interposed between the middle parts of the side panels 76 and dividing the chair body 72 into a rear space 72S and a front space 72T. A seat 78 is formed on the seat support plate 75. In addition, a number of cutouts 77a are formed on the upper edge of the intermediate panel 77 to form a gap 72U between the seat support plate 75, and the rear space 72S and the front space 72T of the chair body 72 are connected through the cutouts 77a.

As explained above, the booth B forms an internal space IS isolated from the external space OS, and as shown in Figures 4, 12 and 14, air flow paths 8(V), 8(W) that guide the air AI while redirecting it are formed in the first and second structures V, W that face the internal space IS, and one end of the air flow paths 8(V), 8(W) is connected to the external space OS and the other end is connected to the internal space IS.

4 and 12, the first structure V is a box-shaped chair 7 having a seat 78 on its upper surface, and the rear space 72S and the front space 72T of the chair body 72 are connected to each other through a notch 77a provided at the upper end of the intermediate plate 77 to form an air flow path 8(V). One end of the air flow path 8(V) is connected to the external space OS through the inner space 71S of the chair base 71, the notch 16a of the rug 16, the notch 15a of the floor plate 15, and the ventilation port 11a of the base body 11. The other end of the air flow path 8(V) is connected to the inner space 71S of the chair base 71, which is connected to the front space 72T, and to the internal space IS through the communication port 71b opened in the front frame material 71a of the chair base 71. That is, the air flow path 8(V) is opened to the bottom surface Ba of the booth B facing the building floor F. Sound-absorbing material 70 is attached to the inner wall surface of air flow path 8 (V). Specifically, sound-absorbing material 70 is attached to the inner surfaces of front plate 73, rear plate 74, seat support plate 75, and side plate 76 of chair body 72, and to both sides of middle plate 77. Note that the sound-absorbing material 70 attached to the inner surface of side plate 76 is not shown. Sound-absorbing material 70 has an uneven surface facing air flow path 8 (V) and is made of a cushioning material such as slab urethane.

The second structure W is the ceiling 5 having the double wall structure described above, and as shown in Figures 4 and 14, an air flow path 8 (W) is formed between the ceiling body 51 (P), (R) and the ceiling panel 56 (P), (R). The air flow path 8 (W) is formed inside the left and right ceiling units P and R, and the horizontal reinforcement 53 extending forward and backward has an opening 53a that allows the air AI to flow. One end of the air flow path 8 (W) is connected to the external space OS via the ventilation fan 57, and the other end is connected to the internal space IS through the cutout 35a formed at the upper end of the sound-absorbing panel 35 (U) of the side wall 3. In other words, this air flow path 8 (W) is opened to the top surface Bb of the booth B facing the architectural ceiling E.

Here, FIG. 1 is an overall perspective view of the booth B. FIG. 2 is a front view of the booth B, and FIG. 3 is a plan view of the same.

This booth B has a symmetrical shape, and while Figure 12 shows only the air flow path 8 (V) inside the chair 7 on the left side, and Figure 14 shows only the air flow path 8 (W) inside the left ceiling unit P, a similar air flow path 8 (V) is also formed inside the chair 7 on the right side, and a similar air flow path 8 (W) is also formed inside the right ceiling unit P.

The booth B described above can be anchored to the building floor F when assembled, and the detailed structure for this purpose is as follows:

As described above, this booth B has a base plate 1 that covers the underside of the internal space IS, and as shown in Figures 15 to 17, casters 17 and adjusters 18 that disable the rolling function of the casters 17 are provided on the underside of the base plate 1. An opening 11b that connects the internal space IS to the external space OS is provided in the base plate 1, and a fixing device 19 for fixing the base plate 1 to the building floor F is arranged near the opening 11b.

The caster 17 is attached to the horizontal reinforcement (structural member) 13 extending from the front to the rear of the base plate 1 and the horizontal reinforcement 12 extending from left to right via the mounting member 1X, and is a normal one that includes a base 17a screwed to the mounting member 1X, a caster body 17b connected to the base 17a so as to be horizontally rotatable, and a wheel 17c journaled on the caster body 17b, as shown in Figs. 16 and 17. The mounting member 1X is a box-shaped one that includes a top plate 1Xa that is rectangular in plan view and a hanging plate 1Xb that hangs down from each side of the top plate 1Xa, and the caster 17 is screwed to the top plate 1Xa. The two perpendicular hanging plates 1Xb of the mounting member 1X are attached to the horizontal reinforcement 13 extending from the front to the rear and the horizontal reinforcement 12 extending from left to right, which are mutually perpendicular, and are rigidly connected by welding or the like. Thus, the mounting member 1X also plays the role of a reinforcing member that firmly connects the orthogonal horizontal reinforcing members 12, 13 (orthogonal structural members). In this embodiment, such mounting members 1X are provided at each corner of the left and right bottom units L and N, and at each of the four corners of the middle bottom unit M, and the casters 17 and adjusters 18 are supported by each mounting member 1X. As shown in Figures 16 and 17, the adjuster 18 is equipped with a screw shaft 18a screwed into a screw hole (not shown) of the caster body 17b, and a grounding body 18b provided at the lower end of the screw shaft 18a, and the height position of the grounding body 18b can be changed by screwing the screw shaft 18a forward and backward relative to the caster body 17b.

On the other hand, the fixing device 19 is attached to the horizontal reinforcement 13 extending in the front-rear direction, which is a structural member of the base plate 1 that supports the casters 17 and adjusters 18. That is, as shown in Figures 16 to 18, the horizontal reinforcement 13 extending in the front-rear direction is made of sheet metal and includes a top plate 13a and side plates 13b, 13c hanging down from both the left and right edges of the top plate 13a, with the aforementioned mounting member 1X supporting the casters 17 and adjusters 18 being rigidly connected to one side plate 13b, and the fixing device 19 being provided on the other side plate 13c. The fixing device 19 is made of sheet metal and includes a horizontal portion 19a that is attached to the building floor F and an upright portion 19b that stands up from one end of the horizontal portion 19a, for example, as shown in Figures 16 to 18. The horizontal portion 19a of the fixing device 19 has a screw insertion hole t for inserting an anchor bolt T driven into the building floor F, and the fixing device 19 is fixed to the building floor F by screwing a nut Q into the tip of the anchor bolt T inserted into the screw insertion hole t. The upright portion 19b of the fixing device 19 has a screw insertion hole 19d for inserting a set screw 19c for fixing the fixing device 19 to the horizontal reinforcement 13. That is, the fixing device 19 can be fixed to the horizontal reinforcement 13 by screwing the set screw 19c inserted into the screw insertion hole 19d into the nut 19e fixed to the side plate 13c of the horizontal reinforcement 13. The screw insertion hole 19d is an elongated hole extending vertically, and the fixing device 19 can be tightened and fixed after adjusting the relative fixing position of the fixing device 19 to the base plate 1.

The fixing device 19 is disposed inside the outer edge of the base plate 1 in a plan view. The opening 11b is provided at a position where the fixing device 19 can be accessed from the internal space IS. Therefore, all anchoring operations of the base plate 1 using the fixing device 19 can be performed from the internal space IS. That is, in the final assembly state of the booth B, the opening 11b is closed by the lid 11c and covered by the floor plate 15 and the mat 16, but before the lid 11c, the floor plate 15, and the mat 16 are attached or removed, the fixing device 19 can be accessed from the internal space IS through the opening 11b. The lid 11c is, for example, a flat plate having a quadrilateral shape, and is removably attached to the opening end surface of the opening 11b using screws 11d as shown in FIG. 18.

Here, Fig. 15 is a perspective view of the base plate 1 with the floor plate 15 and mat 16 omitted, and parts of the base body 11 and the horizontal reinforcement members 13 extending in the front-rear direction are cut away to clearly show the casters 17, adjusters 18, and fixtures 19. Fig. 16 is an enlarged view of the main parts in Fig. 15 as seen from the arrow H. Fig. 17 is an enlarged view of the main parts in Fig. 15 as seen from the arrow I. Fig. 18 is an exploded perspective view showing the mounting manner of the fixtures 19 and the lid 11c.

A booth B with this configuration can be installed and used as appropriate in spaces such as an office, a train station, or an exhibition hall, and work or meetings can be carried out within the internal space IS using tables 6 and chairs 7. In this case, since the internal space IS is surrounded by the base plate 1, surrounding walls, and ceiling 5, it is isolated from the external space OS formed between the building floor F and the building ceiling E, making it possible to concentrate on work or meetings.

Moreover, since the base plate 1 of the booth B has casters 17 and adjusters 18, it can be assembled in a large space, etc., and then moved to a required location by the casters 17, and then the height position of each part can be adjusted by the adjusters 18 to install it in an appropriate position. The installation location of the booth B can be easily changed by a similar method. Furthermore, in addition to the casters 17 and adjusters 18, the base plate 1 is fixed to the building floor F by the fixing device 19, so that even if an unexpected external force acts on the booth B after installation, the position of the booth B can be effectively prevented from shifting. In this embodiment, an opening 11b is provided that connects the internal space IS to the external space OS, and the above-mentioned fixing device 19 is arranged near the opening 11b, so that the anchoring work of the base plate 1 can be performed from the internal space IS side, even though the fixing device 19 is arranged inside the outer edge of the base plate 1 in a plan view. Therefore, even when the booth B is installed in a corner of a room, the base plate 1 can be firmly fixed to the building floor F, and the problem that may occur when the anchoring work of the base plate 1 is performed from the outside of the booth B, that is, when the back surface of the booth is butted against the wall surface of the building and such booths are arranged side by side, the anchoring work of the base plate 1 is very difficult to perform in a recessed position, does not occur. Furthermore, according to this configuration, since the fixing device 19 is arranged inside the outer edge of the base plate 1 in a plan view, the presence of the fixing device 19 does not cause problems such as impairing the appearance of the booth B or obstructing passage. Furthermore, in this embodiment, the fixing device 19 is attached to the structural material (the horizontal reinforcement 13 extending in the front and rear) of the base plate 1 that supports the caster 17 and the adjuster 18. In other words, the mounting member 1X of the caster 17 and the adjuster 18 and the fixing device 19 are attached to the horizontal reinforcement 13, which is a common structural material. Therefore, the configuration of the structural parts that are subjected to the load can be simplified, facilitating strength design, and it is possible to reduce the number of parts and manufacturing man-hours.

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

For example, while the embodiment described above applies the present invention to a two-person booth B, the present invention may also be applied to a four-person booth B2 as shown in FIG. 19, or a one-person booth B3 as shown in FIG. 20. In FIG. 19 and FIG. 20, parts corresponding to the embodiments described above are given the same reference numerals, and descriptions thereof will be omitted. In the one-person booth B3 shown in FIG. 20, the base body 1 and the top board body 5 are not divided into left and right, and the front wall 2 consists only of a door panel 22. In addition, only a table (not shown) is arranged in the internal space of this one-person booth B3.

In addition, the fixing device is not limited to one that is screwed to the structural material, but if it can be removed from the structural material as in the above embodiment, the fixing work to the anchor bolt can be performed smoothly. Moreover, if the mounting position of the fixing device can be adjusted in the vertical direction relative to the structural material, the fixing position of the fixing device can be changed according to the adjustment of the adjuster, and the fixing device can be closely attached to the building floor without using spacers or the like.

Furthermore, the shape and size of the opening are not limited to those shown in the illustrated example, but if it is as shown in the illustrated example, it will be possible to operate a tool engaged with the adjuster through the opening when the fixing device is removed, and it will also be possible to adjust the adjuster from the inside space.

The fixing device may also be integrally formed with the adjuster.

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