Description

[Technical field]

[0001] The present invention relates to a chair fixing structure and a space-configuring structure. [Background technology]

[0002] A known structure for fixing a chair to a wall surface is, for example, the method disclosed in Patent Document 1. In the configuration described in Patent Document 1, a holding member that holds the seat is attached to a wall member via a metal mounting base in order to ensure the mounting strength of the seat.

[0003] [Patent Document 1] Utility Model Registration No. 3203041 [Patent Document 2] JP 2017-119969 A Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, a structure has been considered in which a chair is fixed to a space-forming structure (for example, see Patent Document 2 above) that forms an internal space with multiple supports. In this case, it was difficult to fix the chair to the space-forming structure while ensuring the fixing strength of the chair and the dimensional freedom of the chair.

[0005] An object of the present invention is to provide a chair fixing structure and a space-forming structure that can ensure the fixing strength of the chair and the dimensional freedom of the chair. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, a chair fixing structure according to one embodiment of the present invention comprises a first support pillar and a second support pillar extending in the vertical direction, a panel spanning between the first support pillar and the second support pillar, a horizontal frame spanning between the first support pillar and the second support pillar on one side of the panel in the thickness direction relative to the panel, and a chair fixed to the horizontal frame.

[0007] According to this embodiment, the chair is fixed to a horizontal frame spanning the first and second pillars, so that the chair's fixing strength can be ensured regardless of the strength or material of the panel, unlike when the chair is fixed via a panel. In addition, because the chair is fixed to the support pillars via the horizontal frame, the width of the chair does not depend on the distance between the pillars, unlike a configuration in which the chair is directly suspended between the first and second support pillars, which improves the flexibility of the chair dimensions.

[0008] In the above-described embodiment of the chair fixing structure, a support mechanism may be provided whose upper end is connected to the seat of the chair and whose lower end is connected to the horizontal frame or the floor surface at a portion of the seat that is located closer to the horizontal frame than the center in the thickness direction. According to this aspect, the lower end of the support mechanism is connected to the horizontal frame or the floor surface at a portion of the seat that is located closer to the horizontal frame, making it easier to ensure space below the seat.

[0009] In the chair fixing structure of the above aspect, the width of the chair may be narrower than the distance between the first support pillar and the second support pillar. According to this aspect, the intervals between the support columns can provide a space separate from the space for installing chairs, thereby improving space efficiency.

[0010] In the chair fixing structure of the above aspect, the horizontal frame may bridge between the first support pillar and the second support pillar at a portion located below the seat surface of the chair. According to this aspect, since the horizontal frame is positioned below the seat surface, the horizontal frame is difficult to see, which improves the appearance of the fixing structure of the chair.

[0011] A spatial structure according to one aspect of the present invention has a first support and a second support extending in the vertical direction, and a panel spanning between the first support and the second support, and is equipped with a partition member that partitions an internal space, a horizontal frame that spans between the first support and the second support on one side of the panel in the thickness direction, and a chair fixed to the horizontal frame. According to this aspect, the chair is fixed to the support column via the horizontal frame as described above, so that the fixing strength of the chair and the dimensional freedom of the chair can be secured. Therefore, a chair of the desired size can be stably installed in the limited space in the space-forming structure.

[0012] In the spatial structure of the above aspect, the partition member may include a third support pillar located on one side of the chair in the thickness direction, and a beam connecting at least one of the first support pillar and the second support pillar, and the upper ends of the third support pillar. According to this aspect, the strength of the space-forming structure can be ensured by the pillars supporting each other through the beams. Therefore, the chairs fixed to the pillars through the horizontal frames can be set up more stably. Effect of the Invention

[0013] According to each of the above aspects, the fixing strength of the chair and the degree of freedom in dimensions of the chair can be ensured. [Brief description of the drawings]

[0015] Next, an embodiment of the present invention will be described with reference to the drawings. In each embodiment (and modified examples) described below, the same reference numerals may be used to designate corresponding configurations, and the description may be omitted. In the following description, expressions indicating relative or absolute arrangements, such as "parallel," "orthogonal," "center," and "coaxial," do not only strictly indicate such arrangements, but also indicate a state in which the components are relatively displaced with an angle or distance to an extent that the same function is obtained, or with a tolerance.

[0016] [Booth 1] FIG. 1 is a perspective view of the booth 1. As shown in FIG. 1, the booth 1 is installed on a floor surface F in various facilities such as an office or a public institution. The booth 1 is used, for example, when performing work such as office work in a state isolated from the outside space. The booth 1 of this embodiment is configured such that a lift-top fixture 11 and a chair 12 are installed in a booth body 13 (internal space S) facing each other. In the following explanation, directions such as front / back, up / down, left / right, etc. refer to directions as seen by a user of the chair 12. Therefore, the front / back / left / right directions of the lift-top fixture 11 are based on the direction that a user of the chair 12 faces.

[0017] <Booth body 13> The booth body 13 is formed in a rectangular parallelepiped shape extending in the vertical direction. Specifically, the booth body 13 includes a frame unit 21, a panel unit 22, an entrance / exit unit 23, and a ceiling unit 24. The frame unit 21 forms the contour (outer shape) of the booth body 13. The frame unit 21 includes a plurality of support column bodies 25 and a plurality of beams 26. The outer shape of the booth body 13 can be appropriately changed to a polygonal prism shape other than a rectangular parallelepiped, a cylindrical shape, or the like.

[0018] Each support body 25 extends in the vertical direction at a portion located at each corner of the booth body 13 in a plan view. Each support body 25 is installed on the floor surface F via an adjuster. In a cross-sectional view perpendicular to the vertical direction, each support body 25 in this embodiment is formed in a fan shape convex toward the outside of the booth body 13. Therefore, among each support body 25, the surface (inner surface) facing the adjacent support body 25 is formed as a flat surface. The number of each support body 25 can be appropriately changed. For example, when the booth body 13 has a polygonal shape in a plan view, the support body 25 may be disposed at each corner. Also, the support body 25 may be disposed between adjacent corners in the booth body 13.

[0019] The beam 26 spans between the upper ends of adjacent support body 25. In a cross section along the vertical direction, the beam 26 is formed in a fan shape that protrudes toward the outside of the booth body 13. Therefore, the lower surface of each beam 26 and the surface (inner surface) facing the adjacent beam 26 are formed as flat surfaces. However, the cross-sectional shape of the support body 25 and the beam 26 can be appropriately changed to a rectangular shape, a circular shape, or the like. The connecting portion between the support body 25 and the beam 26 is covered by a corner member 27. The outer surface of the corner member 27 is formed in a curved shape that smoothly connects to the outer surfaces of the support body 25 and the beam 26.

[0020] The panel unit 22 is disposed in an opening (hereinafter simply referred to as the opening) in the frame unit 21 defined by a pair of adjacent support body bodies 25 and a beam 26 spanning between the pair of support body bodies 25, and separates the external space from the internal space S. That is, the panel unit 22 constitutes the side walls of the booth body 13. The panel units 22 in this embodiment constitute the front and rear side walls and the right side wall of the chair 12. The panel units 22 are configured in the same manner as each other. Therefore, in the following explanation, the panel unit 22 (rear wall unit 22A) constituting the rear wall of the booth body 13 will be used as an example.

[0021] FIG. 2 is a cross-sectional view corresponding to the line II-II in FIG. As shown in FIG. 2, the rear wall unit 22A includes a frame material 31, and an outer panel 32 and an inner panel 33 provided on both the front and rear sides of the frame material 31. The frame material 31 is formed in a frame shape arranged along the inner peripheral edge of the rear opening of the frame unit 21. The frame material 31 is fixed to the inner surfaces of the pillar main body 25 and the beam 26. Of the frame material 31, a vertical frame portion 35 extending in the vertical direction is formed with a locking hole 36. The locking holes 36 are open on both the front and rear sides and are formed at intervals in the vertical direction. In this embodiment, the pillar main body 25 and the vertical frame portion 35 described above constitute the pillars (first pillar and second pillar).

[0022] The outer panel 32 covers the frame material 31 from the rear. The inner panel 33 covers the frame material 31 from the front, with the locking holes 36 opening forward in the vertical frame portions 35 exposed. Each panel 32, 33 in this embodiment preferably has light-shielding and sound-absorbing properties. Such materials may include a metal core covered with an outer skin such as cloth, or compressed nonwoven fabric. However, each panel 32, 33 may be made of a light-transmitting material such as glass or acrylic resin.

[0023] As shown in Fig. 1, the entrance / exit unit 23 is disposed in the left opening of the openings of the frame unit 21. The entrance / exit unit 23 is a so-called single sliding door. Specifically, the entrance / exit unit 23 is provided with a fixed door 41 and a sliding door 42 on a sash 40 fixed along the inner peripheral edge of the left opening of the frame unit 21.

[0024] The fixed door 41 is disposed at the front within the left opening of the frame unit 21. The fixed door 41 is fixed to the sash 40. At the rear of the left opening of the frame unit 21, the portion defined by the fixed door 41 and the sash 40 constitutes an entrance / exit 43 that connects the inside and outside of the booth body 13. The sliding door 42 is configured to be able to open and close the entrance 43. In this embodiment, the sliding door 42 is supported by the sash 40 so as to be able to slide in the front-rear direction. When the sliding door 42 is in the open position (a position where it overlaps with the fixed door 41), the booth 1 allows entry and exit from the inside and outside of the booth body 13 through the entrance 43.

[0025] In this embodiment, the fixed door 41 and the sliding door 42 are configured by fixing a light-transmitting partition material such as glass or acrylic resin to the inside of a frame material. However, the fixed door 41 and the sliding door 42 may have light-shielding properties. The entrance / exit unit 23 is not limited to a single sliding door, and can be appropriately changed to a sliding door, a hinged door, a folding door, or the like. Furthermore, in the booth body 13 of this embodiment, the left opening of the frame unit 21 is set as the entrance / exit 43, but this configuration is not limited to this. It is sufficient that at least one entrance / exit is provided in either the front, rear, left, or right direction. Furthermore, in this embodiment, a configuration in which the booth body 13 is surrounded on all four sides by the panel unit 22 or the entrance / exit unit 23 has been described, but this configuration is not limited to this. It is sufficient that the booth body 13 has a closed area formed by connecting adjacent support bodies 25 in a plan view.

[0026] The ceiling unit 24 includes a bridge portion 45 that bridges between the portions of the beams 26 that face each other in the left-right direction. A plurality of bridge portions 45 are provided at intervals in the front-rear direction. That is, the ceiling unit 24 of this embodiment vertically connects the external space and the internal space S through the gaps between the adjacent bridge portions 45. However, the ceiling unit 24 may completely separate the external space and the internal space S. In addition, the booth body 13 may have a floor material unit separately provided on the floor surface F.

[0027] <Lift-top display unit 11> Fig. 3 is a cross-sectional view of the booth 1 from the left side, showing the chair 12 in the seated position. Fig. 4 is a cross-sectional view of the booth 1 from the left side, showing the chair 12 in the seated position. As shown in Figures 3 and 4, the lifting tabletop fixture 11 is installed at the front of the booth body 13. The lifting tabletop fixture 11 includes a pair of legs 51 spaced apart in the left-right direction, and a tabletop 52 supported by the legs 51 from below. The legs 51 include a leg bracket 55, a lifting unit 56, and an upper support 57. Each leg 51 is disposed along one of the support pillar bodies 25 located on both the front left and right sides. Therefore, the lifting tabletop fixture 11 of this embodiment is disposed across the entire left-right area of ​​the booth body 13. However, the left-right width of the lifting tabletop fixture 11 can be changed as appropriate. The pair of legs 51 each have the same configuration. Therefore, in the following explanation, the leg 51 disposed at the front left part of the booth body 13 will be used as an example.

[0028] The leg bracket 55 is formed in a square tube shape extending vertically along the support body 25 at the left front portion inside the booth body 13. The leg bracket 55 is equipped with a locking claw (not shown) protruding forward. The locking claw is locked into a locking hole 36 formed in the vertical frame portion 35 of the panel unit 22 (front wall unit 22B) that constitutes the front wall. In other words, the lifting tabletop fixture 11 is fixed to the booth body 13 via the leg bracket 55. However, the lifting tabletop fixture 11 does not have to be connected to the booth body 13.

[0029] The lifting unit 56 is configured to be expandable and contractable in the vertical direction. Specifically, the lifting unit 56 includes a plurality of square tubes with different outer shapes in a plan view. The lifting unit 56 is configured by inserting a square tube with a smaller outer shape in a plan view inside a square tube with a larger outer shape in a plan view among the square tubes described above. The lifting unit 56 is configured to be expandable and contractable in the vertical direction by the operation of a drive mechanism (not shown) causing each square tube to move relatively in the vertical direction. The lifting unit 56 is installed on the floor surface F via an adjuster, with its lower portion (the rectangular tube having the largest outer shape in a plan view) housed within the leg bracket 55 described above.

[0030] The upper support 57 is connected to an upper end of the lifting unit 56. The upper support 57 extends rearward from the lifting unit 56 in a cantilever manner.

[0031] The top plate 52 spans between the upper ends of the legs 51. Specifically, an upper support 57 is connected to the underside of the top plate 52. The upper support 57 extends in the front-rear direction along both the left and right ends of the top plate 52. In this embodiment, the lifting unit 56 is located forward of the center of the top plate 52 in the front-rear direction. This makes it easier to ensure a space below the top plate 52.

[0032] The top plate 52 has a working surface 52a facing upward. The working surface 52a is a flat surface perpendicular to the up-down direction. The top plate 52 is configured to be movable in the up-down direction in accordance with the extension and contraction operation of the lifting unit 56. As a result, the working surface 52a of the top plate 52 is configured to be height-adjustable while forming a certain angle (0° in this embodiment) with the floor surface F. The top plate 52 may be provided with, for example, a wiring insertion port or a wiring duct.

[0033] FIG. 5 is a cross-sectional view corresponding to the line VV in FIG. As shown in Fig. 5, the top plate 52 is formed in a trapezoidal shape in a plan view. Specifically, the front end edge of the top plate 52 extends linearly in the left-right direction. Both left and right end edges of the top plate 52 each extend linearly in the front-rear direction. The shape of the top plate 52 in a plan view can be appropriately changed to a rectangular shape, a semicircular shape, or the like.

[0034] The rear edge of the top plate 52 includes a linear extension portion 58 and an inclined portion 59 . The straight extension portion 58 extends in a straight line from the rear end of the right edge of the top plate 52 toward the left side. In this embodiment, the straight extension portion 58 is located rearward of the center in the front-rear direction of the booth body 13. However, the position of the straight extension portion 58 in the front-rear direction may be either the center or forward of the center. In addition, the left end of the straight extension portion 58 is located to the left of the center in the left-right direction of the booth body 13. However, the left-right length of the straight extension portion 58 relative to the left-right dimension of the booth body 13 can be changed as appropriate.

[0035] An operation part 56a of the lifting unit 56 is disposed on the lower surface of the tabletop 52, in a portion located closer to the linear extension part 58. In this embodiment, the operation part 56a is disposed on the right side of the lower surface of the tabletop 52.

[0036] Inclined portion 59 is connected to the left end of linear extension portion 58. Inclined portion 59 is linearly inclined forward as it approaches the left side (entrance / exit 43). The left end of inclined portion 59 is connected to the left edge of tabletop 52. Therefore, the length of tabletop 52 in the front-to-rear direction is uniform at the position corresponding to linear extension portion 58, and gradually becomes shorter as it approaches the left side at the portion corresponding to inclined portion 59. Note that inclined portion 59 is not limited to being linear, and may be arc-shaped or stepped, as long as it extends further forward than linear extension portion 58.

[0037] <Chair 12> 3 and 4, the chair 12 faces the liftable tabletop fixture 11 in the front-rear direction. The chair 12 is arranged along the rear wall unit 22A inside the booth body 13. The chair 12 of this embodiment can be used by a user in both a seated position (see FIG. 4) and a standing position (see FIG. 3).

[0038] FIG. 6 is a perspective view showing a state in which the attachment mechanism 60 is attached to the booth body 13. As shown in FIG. 6, the chair 12 is connected to the booth body 13 via an attachment mechanism 60. The attachment mechanism 60 includes a horizontal frame 61, a backrest bracket 62, and a decorative cover 63. The horizontal frame 61 is attached to the lower part of the rear wall unit 22A from the front of the rear wall unit 22A. A plurality of (for example, two) horizontal frames 61 are attached at intervals in the vertical direction. Specifically, the horizontal frame 61 in this embodiment includes a mounting plate 65 and a locking portion 66.

[0039] The mounting plate 65 extends in the left-right direction along the front surface of the rear wall unit 22A. The length of the mounting plate 65 in the left-right direction is equal to that of the rear wall unit 22A. The locking portions 66 protrude rearward from both left and right ends of the mounting plate 65. The locking portions 66 are respectively locked in locking holes 36 that open forward in the vertical frame portions 35 that constitute the rear wall unit 22A. In this way, the horizontal frame 61 is fixed to the pillar main body 25 via the rear wall unit 22A. The horizontal frame 61 may be configured to be directly fixed to the pillar main body 25. The horizontal frame 61 is not limited to being locked via the locking portions 66, and can be appropriately modified by means of screws, welding, or the like.

[0040] The backrest brackets 62 are engaged in the locking holes 36 located above the horizontal frames 61 (locking portions 66) in the vertical frame portions 35 constituting the rear wall unit 22A. In this embodiment, a pair of left and right backrest brackets 62 are attached in multiple pairs (for example, two pairs) spaced apart in the vertical direction.

[0041] The decorative cover 63 covers each of the horizontal frames 61 from the front at the lower left side of the rear wall unit 22A. The decorative cover 63 is formed in a plate shape with its thickness direction being in the front-to-rear direction. The front surface of the decorative cover 63 is formed in a flat surface perpendicular to the front-to-rear direction. In this embodiment, the decorative cover 63 is configured such that a cushioning material that covers a base material from the front is covered by an outer skin. The decorative cover 63 (base material) is attached to each of the horizontal frames 61 by, for example, locking or the like.

[0042] FIG. 7 is a perspective view of the chair 12 as seen from the rear. As shown in FIG. 7, the chair 12 includes a base 71, a backrest 72 (see FIG. 1), a seat 73, a connection mechanism 74, a biasing member 75, and a cover member .

[0043] <Base 71> The base 71 is attached to the horizontal frame 61 at a portion located in front of the rear wall unit 22A (see FIG. 1) and to the right of the decorative cover 63. That is, the left-right length of the base 71 is shorter than the length of the horizontal frame 61 (the distance between adjacent pillar bodies 25 in the left-right direction). However, the length of the base 71 may be equal to the length of the horizontal frame 61. The base 71 is formed in a C-shape that opens forward in a plan view. Specifically, the base 71 includes a rear plate 81 and a side wall member 82.

[0044] The rear plate 81 extends in the left-right direction with the thickness direction being the front-rear direction. The rear plate 81 covers each of the horizontal frames 61 from the front at the bottom of the rear wall unit 22A. The rear plate 81 is attached to each of the horizontal frames 61 by, for example, screws. Therefore, the base 71 is fixed to the pillar main body 25 via the horizontal frames 61 and the vertical frame portions 35. However, the method of attaching the rear plate 81 can be changed as appropriate.

[0045] As shown in Figs. 3 and 4, the sidewall member 82 is formed in a block shape. The sidewall member 82 protrudes forward from both left and right ends of the rear plate 81. The lower surface of the rear plate 81 is in contact with the floor surface F via an adjuster. The upper surface of the sidewall member 82 is an inclined surface 82a that extends downward toward the front. In this embodiment, the entire upper surface of the sidewall member 82 is the inclined surface 82a. However, as long as the upper surface of the sidewall member 82 does not interfere with the seat 73, it may be a curved surface or a stepped surface, or may be a flat surface perpendicular to the up-down direction.

[0046] <Backrest 72> 1 and 3, the backrest 72 is attached from the front to a portion of the rear wall unit 22A that is located above the base 71. The backrest 72 is a plate-like member having a thickness in the front-rear direction, and is longer in the left-right direction than the base 71.

[0047] The backrest 72 is fixed to the backrest bracket 62 by screws or the like. As a result, the backrest 72 is spanned between the support body 25 via the vertical frame portion 35 of the rear wall unit 22A. Meanwhile, the left side (the entrance 43 side) of the lower end of the backrest 72 is connected to the upper end of the decorative cover 63. In this embodiment, the front surface of the backrest 72 is disposed flush with the front surface of the decorative cover 63. The right side of the lower end of the backrest 72 is connected to the upper end of the base 71 (rear panel 81). The backrest 72 is formed of the same material as the decorative cover 63 described above. The backrest 72 may be configured to be located only above the base 71. Furthermore, the backrest 72 and the decorative cover 63 may be formed integrally. In that case, no gap is generated between the backrest 72 and the decorative cover 63, and a good appearance can be obtained.

[0048] <Locus 73> The seat 73 is connected to the base 71 via a connection mechanism 74. As shown in Figs. 3 and 4, the seat 73 is configured to be movable between a seating position (see Fig. 4: first position) where the seat surface 73a faces upward, and an upright position (see dashed line in Fig. 3: second position) where the seat surface 73a faces forward. In the following explanation, unless otherwise specified, the seat 73 is in the seating position. In addition, the front side of the seat 73 in the seating position may be referred to as the first side, and the rear side may be referred to as the second side.

[0049] The seat 73 has the same length in the left-right direction as the base 71, and has a triangular appearance in a side view. The seat 73 is constructed with a framework made of plywood or the like covered with cushioning material and upholstery material. Specifically, the seat 73 is thickest in a portion (hereinafter referred to as the thickest portion 90) toward the front-to-rear center, and becomes gradually thinner from the thickest portion 90 toward both sides in the front-to-rear direction. The seat 73 comprises a main portion 91 and side portions 94.

[0050] The main portion 91 is formed in a plate shape extending in the left-right direction with the thickness direction being the up-down direction. The upper surface of the main portion 91 constitutes the above-mentioned seat surface 73a. In this embodiment, the seat surface 73a is a flat surface formed along a plane perpendicular to the up-down direction.

[0051] In the plan view shown in FIG. 5, the front edge of the main part 91 extends linearly in the left-right direction. Therefore, the front edge of the main part 91 extends parallel to the linear extension part 58 of the top plate 52. In the illustrated example, the length of the seat 73 in the left-right direction is slightly shorter than the linear extension part 58 of the top plate 52. However, the lengths of the base 71, the seat 73, and the top plate 52 can be changed as appropriate. By setting the length of the base 71 and the seat 73 in the left-right direction to be equal to or less than the length of the linear extension part 58, an entrance / exit space S1 in which no fixtures are installed around the entrance / exit 43 is formed in the internal space S of the booth body 13. The entrance / exit space S1 can be used for entering and exiting the booth body 13, for storing luggage, etc.

[0052] The length of the seat 73 (main portion 91) in the front-to-rear direction is set to be equal to or less than half that of the side wall member 82. In this embodiment, the front end surface of the side wall member 82 is located rearward of the center of the main portion 91 in the front-to-rear direction. Also, the front end portion of the main portion 91 overlaps with the rear end portion of the table top 52 in a plan view. That is, the front edge of the main portion 91 is located forward of the rear edge of the table top 52. However, the front edge of the main portion 91 may be located at the same position as the rear edge of the table top 52 or rearward.

[0053] As shown in Fig. 4, the side portions 94 are provided on both left and right ends of the main portion 91 over the entire length in the front-rear direction. The outer surface of the side portion 94 is disposed flush with the outer surface of the side wall member 82 (at a position where they overlap in a plan view). Below the main portion 91, the space surrounded by the side portions 94 forms a recess 98 (see Fig. 7) that opens downward and toward both the front-rear direction and the rear direction.

[0054] The side portion 94 is formed with a first side escape portion 95 and a second side escape portion 96, so that the side portion 94 is formed in a triangular shape whose length in the front-rear direction tapers downward in a side view. The first side escape portion 95 is formed by opening forward and downward from the front end edge to the thickest portion 90 of the side portion 94. An edge portion 95a of the first side escape portion 95 is inclined backward as it extends downward. The second side escape portion 96 is formed by opening rearward and downward from the rear end edge of the side portion 94 to the thickest portion 90. An edge portion 96a of the second side escape portion 96 is inclined forward as it extends downward. In this embodiment, the angle between the seat surface 73a and the edge portion 95a is larger than the angle between the seat surface 73a and the edge portion 96a.

[0055] A side portion 94 of the seat 73 faces the side wall member 82. In the seated position, an edge portion 96a of the seat 73 extends along the inclined surface 82a of the side wall member 82. In the illustrated example, the edge portion 96a and the inclined surface 82a are arranged parallel to each other.

[0056] 3, the edge 95a of the side portion 94 extends along the inclined surface 82a of the side portion 94. In the illustrated example, the edge 95a and the inclined surface 82a are arranged parallel to each other. Note that the seat 73 may be supported (abutted) from below by the side wall member 82 in either the sitting position or the standing position.

[0057] As shown in Fig. 7, the connection mechanism 74 includes a link mechanism 120 and a coupling portion 121. The link mechanism 120 connects the underside of the seat 73 and the front surface of the base 71 by, for example, a four-joint link or the like. A pair of link mechanisms 120 are provided on the left and right sides inside the base 71. The fixed structure of the chair 12 of this embodiment is composed of the chair 12, the support pillar main body 25, the panels 32, 33, the vertical frame portion 35, the horizontal frame 61, etc. Furthermore, the base 71 and the connection mechanism 74 compose the support mechanism of this embodiment.

[0058] The connecting portion 121 extends in the left-right direction along the rear plate 81 behind the link mechanisms 120. The connecting portion 121 bridges between the pair of link mechanisms 120.

[0059] FIG. 8 is a cross-sectional view corresponding to FIG. 3, showing the seat 73 in a state between the seated position and the standing position. As shown in Figs. 7 to 9, as the seat 73 moves from the seated position to the standing position by the operation of the link mechanism 120, the second side end moves upward while the first side end moves backward. As a result, the seat 73 is in the standing position with the seat surface 73a facing forward. The seat 73 may move between the seated position and the standing position by a configuration other than the link mechanism 120 (for example, a slider or a slide groove). The seat 73 may also change between the seated position and the standing position by having the rear end rotatably connected to the base 71 (so-called flip-up type). Furthermore, the seat 73 may not be movable, but may be fixed in the seated position.

[0060] The biasing member 75 biases the seat 73 toward the upright position. The biasing member 75 is, for example, a gas spring. The lower end (piston rod) of the biasing member 75 is connected to the rear plate 81 so as to be rotatable about an axis along the left-right direction. Meanwhile, the upper end (cylinder) of the biasing member 75 is connected to the lower surface of the main part 91 so as to be rotatable about an axis along the left-right direction. Specifically, the upper end of the biasing member 75 is connected at a portion located toward the rear of the seat 73 when the seat 73 is in the seated position. Note that the biasing member 75 is not limited to a gas spring, and can be appropriately changed to a torsion spring or the like. Also, the biasing member 75 is not an essential component.

[0061] In this embodiment, at least a portion of the connection mechanism 74 and the biasing member 75 is surrounded from both the left and right sides by the side wall members 82 of the base 71 and the side portions 94 of the seat 73 in both the seated position and the standing position. Specifically, the lower portions of the connection mechanism 74 and the biasing member 75 are housed inside the pair of side wall members 82. Meanwhile, the upper portions of the connection mechanism 74 and the biasing member 75 are housed inside the pair of side portions 94 (inside the recesses 98). As a result, at least a portion of the connection mechanism 74 and the biasing member 75 cannot be seen in a side view.

[0062] The cover member 76 is formed in a cylindrical shape surrounding the connection mechanism 74 and the biasing member 75 between the base 71 and the seat 73. The cover member 76 is preferably formed of, for example, a stretchable woven fabric.

[0063] [How to use Booth 1] Next, a method of using the above-mentioned booth 1 will be described. In the following explanation, a method of using the booth 1 in the standing position and a method of using the booth 1 in the sitting position will be mainly described. In the following explanation, the seat 73 is in the standing position due to the biasing force of the biasing member 75, and the tabletop 52 is set to the height used when the seat 73 is in the standing position will be described as an initial state. 1, first, the sliding door 42 is moved to the open position, and the person enters the booth body 13 through the entrance 43. After that, the person enters between the lift-top furniture 11 and the chair 12, and faces the lift-top furniture 11.

[0064] As shown in Fig. 3, when the seat 73 is in the standing position, the seat surface 73a faces diagonally upward and forward, with the first side end positioned downward and the second side end positioned upward. In this state, when a user leans back on the seat 73, the buttocks are supported by the second side end of the seat 73 (sitting position). This allows the user to sit on the seat 73 in an upright position and work facing the lift-top furniture 11.

[0065] Next, when the seat 73 is to be used in a seated position, the second side end is pushed downward with respect to the seat 73 in the upright position shown in Fig. 3. Then, as shown in Fig. 8, the seat 73 moves toward the seated position while resisting the biasing force of the biasing member 75. Specifically, the seat 73 moves toward the seated position along the front surface of the backrest 72 and the inclined surface 82a of the side wall member 82 by sliding the second side end downward and the first side end forward.

[0066] When the seat 73 is in the seated position, the seat surface 73a faces upward, allowing the user to sit on the seat 73 with the area from the buttocks to the thighs supported by the seat surface 73a, as shown in FIG.

[0067] In addition, the user can set the height of the tabletop 52 to suit the seated posture by operating the operation unit 56a. Specifically, when the operation unit 56a is operated, the lifting unit 56 contracts, and the tabletop 52 descends. This allows the user to work on the tabletop 52 while seated on the seat 73.

[0068] When the user stands up while the seat 73 is in the seated position, the seat 73 returns to the standing position due to the biasing force of the biasing member 75. That is, the second side end of the seat 73 moves upward, while the first side end moves backward. As a result, the seat 73 is in the standing position with the seat surface 73a facing forward.

[0069] In this manner, in this embodiment, the seat is configured to include a horizontal frame 61 that spans between the vertical frame portions 35 (pillars) fixed to the pillar main body (pillar) 25 at the front (one side in the thickness direction) of the inner panel (panel) 33, and a chair fixed to the horizontal frame 61. According to this configuration, the chair 12 is fixed to the horizontal frame 61 that is spanned between the vertical frame sections 35. Therefore, unlike when the chair 12 is fixed via the panels 32, 33, the fixing strength of the chair 12 can be ensured regardless of the strength or material of the panels 32, 33. In addition, because the chair 12 is fixed to the vertical frame parts 35 via the horizontal frames 61, the width of the chair 12 does not depend on the distance between the vertical frame parts 35, unlike a configuration in which the chair 12 is directly spanned between the vertical frame parts 35. Therefore, the degree of freedom in the dimensions of the chair 12 can be improved.

[0070] In this embodiment, the configuration is provided with a support mechanism (connection mechanism 74 and base 71) whose upper end is connected to the seat 73 and whose lower end is connected to the horizontal frame 61 or the floor surface F at the rear of the seat 73. According to this configuration, the lower end of the support mechanism is connected to the horizontal frame 61 or the floor surface F at the rear of the seat 73, making it easier to ensure a space below the seat 73.

[0071] In this embodiment, the width of the chair 12 (base 71 and seat 73) is narrower than the distance between adjacent vertical frame portions 35 in the left-right direction. According to this configuration, a space (entrance / exit space S1) separate from the installation space of the chair 12 can be secured by the interval between each vertical frame portion 35. This can improve space efficiency.

[0072] In this embodiment, the horizontal frame 61 is configured to bridge between the vertical frame portions 35 at a portion located below the seat surface 73a of the chair 12. According to this configuration, the horizontal frame 61 is positioned below the seat surface 73a, so that the horizontal frame 61 is difficult to see. Therefore, the appearance of the fixing structure of the chair 12 can be improved.

[0073] In the booth 1 of this embodiment, as described above, the chair 12 is fixed to the vertical frame portion 35 via the horizontal frame 61, thereby ensuring the fixing strength of the chair 12 and the dimensional freedom of the chair 12. Therefore, within the limited space in the booth 1, the chair 12 of the desired dimensions can be stably installed.

[0074] The booth 1 of this embodiment is configured to include beams 26 that connect the upper ends of the support pillar bodies 25 together. According to this configuration, the pillar bodies 25 support each other via the beams 26, thereby ensuring the strength of the booth body (compartment member) 13. Therefore, the chairs 12 fixed to the vertical frame parts 35 via the horizontal frames 61 can be installed more stably.

[0075] (Other variations) Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the scope of the attached claims. In the above embodiment, a configuration has been described in which the chair 12 and the lift-top fixture 11 are installed inside the booth body 13, but the present invention is not limited to this configuration. The chair 12 does not have to be installed inside the booth body 13, and does not have to be installed in combination with the lift-top fixture 11. The chair 12 may also be a sofa, a sofa bed, or the like. In the above embodiment, the booth body 13 is configured by the support body 25 and the panel unit 22, but the configuration is not limited to this. The chair 12 may be fixed to a wall surface configured by the support body 25 and the panel unit 22.

[0076] In the above embodiment, the biasing member 75 is used to hold the seat 73 in the upright position, but the present invention is not limited to this configuration. In the upright position, a mooring member for mooring the seat 73 to the rear wall unit 22A, the backrest 72, or the like may be provided. In addition, the seat 73 only needs to have at least a component facing upward in the seated position and at least a component facing forward in the upright position.

[0077] In the above embodiment, the case where the operation unit is disposed on the right side of the lower surface of the tabletop 52 has been described, but the present invention is not limited to this configuration. For example, the operation unit may be disposed on the lower surface of the tabletop 52 on the entrance / exit 43 side (for example, near the inclined portion 59). In the above embodiment, the base 71 and the seat 73 are fixed to the horizontal frame 61, but the present invention is not limited to this configuration. It is sufficient that at least some of the components of the chair 12 are fixed to the horizontal frame 61. In the above-mentioned embodiment, the seat 73 is supported via the base 71 and the connection mechanism 74 fixed to the horizontal frame 61, but the present invention is not limited to this configuration. The seat 73 may be directly fixed to the horizontal frame 61, for example, as shown in Fig. 9. Also, as shown in Fig. 10, legs 200 that contact the floor surface F may be fixed to the horizontal frame 61, and the seat 73 may be supported by the legs 200. In this case, the seating load acting on the seat 73 is stably supported by the legs 200. By positioning the front end surface of the legs 200 rearward of the center of the seat 73 in the front-rear direction, the amount of overhang of the seat 73 can be secured, and the space below the seat 73 can be secured.

[0078] 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]
