Description

[Technical Field]

[0001] The present invention relates to fixtures and booths. [Background technology]

[0002] Chairs that are switchable in seat position (seat orientation) between when in use and when not in use have been known. This type of chair includes a chair in which the seat and seat support are connected via a guide mechanism such as a link or slider, so that the seat can move between a seated position where the seat faces upward and a standing position where the seat faces forward (see, for example, Patent Documents 1 and 2 listed below). With this configuration, when the seat is in the seated position, the rear end of the seat moves upward while the front end of the seat moves backward, causing the seat to transition to the standing position. This is thought to enable the movement path of the seat when transitioning from the seated position to the standing position to be positioned further backward, compared to a configuration in which the seat rotates around the rear end (flip-up type).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 4-367622 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-4982 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional configuration, the guide mechanism is exposed to the outside, so there is a possibility that an article or the like may become caught in the guide mechanism or the seat.

[0005] The present invention aims to provide fixtures and booths that can prevent items and the like from getting caught. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, one embodiment of the fixture of the present invention comprises a base, a load support section located above the base and having a load support surface that supports a load, a support mechanism that connects the base and the load support section so that the load support section can move between a first position in which the load support surface faces upward and a second position in which the load support surface faces forward, and a cover member that surrounds the entire circumference of the support mechanism between the base and the load support section, and the cover member has an extension and contraction section that extends and contracts in accordance with the displacement of the support mechanism.

[0007] According to this aspect, the entire circumference of the support mechanism between the base and the load support part is surrounded by the cover member, which prevents articles and the like from passing between the base and the load support part and reaching the support mechanism, thereby preventing articles and the like from becoming caught in the load support part or the support mechanism. Furthermore, since the cover member is provided with an expandable portion, the expandable portion expands and contracts in response to the displacement of the support mechanism, thereby preventing the cover member from interfering with the displacement of the support mechanism and allowing the load support member to move smoothly between the first position and the second position.

[0008] In the fixture of the above aspect, the load support portion moves to the second position by the first side end portion, which is the front end portion at the first position, moving rearward while the second side end portion, which is the rear end portion, moves upward, and the extension / contraction portion may cover the support mechanism from the outside in the left-right direction. According to this aspect, when the load support part moves between the first position and the second position, the displacement of the support mechanism is greatest in a side view. Therefore, by covering the support mechanism from the outside in the left-right direction with the expandable part, it is possible to more reliably prevent the cover member from interfering with the displacement of the support mechanism.

[0009] In the fixture of the above aspect, the load support portion moves to the second position by the first side end portion, which is the front end portion in the first position, moving rearward while the second side end portion, which is the rear end portion, moves upward, and the telescopic portion may cover the support mechanism from behind when the load support portion is in the second position. According to this aspect, when the load support unit moves between the first position and the second position, the distance between the load support unit and the base expands and contracts. Therefore, by covering the support mechanism from behind with the expandable unit, it is possible to more reliably prevent the cover member from interfering with the displacement of the support mechanism. In addition, it is possible to prevent items, etc., that fall between the upper end of the base and the load support unit from reaching the support mechanism. This makes it possible to prevent items, etc., from getting caught in the load support unit or the support mechanism.

[0010] In the fixture of the above embodiment, the stretchable portion may be formed by a stretchable band-shaped body that surrounds the entire circumference of the support mechanism between the base and the load support portion, and both ends of the band-shaped body may be joined along the vertical direction at a portion located behind the support mechanism when the load support portion is in the second position. According to this aspect, by joining the band-shaped body behind the load support portion, the joint is less visible to users, thereby improving the aesthetic appearance of the fixture. Furthermore, because the stretch of the expandable section in the left-right direction is small behind the load support section, the joint is less likely to be pulled in the left-right direction, which makes it possible to prevent breakage of the joint over a long period of time.

[0011] In the fixture of the above aspect, the cover member may have a non-stretchable portion that covers the support mechanism from the front. According to this aspect, the support mechanism can be protected from the entry of users' feet, objects, etc. from the front of the fixture.

[0012] The booth according to this aspect comprises a fixture according to any one of the above aspects and a booth body that forms an interior space in which the fixture is installed. According to this aspect, by providing the fixtures according to any of the above aspects, users can use the booth comfortably. [Effects of the Invention]

[0013] According to each of the above aspects, it is possible to prevent objects and the like from getting caught. [Brief explanation of the drawings]

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

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

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

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

[0019] The beams 26 span the space between the upper ends of adjacent support main bodies 25. In a cross-sectional view along the vertical direction, the beams 26 are formed in a fan shape that convex toward the outside of the booth main 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 shapes of the support main bodies 25 and the beams 26 can be changed as appropriate, such as to a rectangular shape or a circular shape. The connecting portions between the support main bodies 25 and the beams 26 are covered by corner members 27. The outer surfaces of the corner members 27 are formed as curved surfaces that smoothly connect to the outer surfaces of the support main bodies 25 and the beams 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 column bodies 25 and a beam 26 spanning the space between the pair of support column bodies 25, and separates the external space from the internal space S. That is, the panel unit 22 forms the side walls of the booth body 13. In this embodiment, the panel units 22 form the front, rear, and right side walls of the chair 12. Note that each panel unit 22 has the same configuration. Therefore, in the following explanation, the panel unit 22 (rear wall unit 22A) that forms the rear wall of the booth body 13 will be used as an example.

[0021] FIG. 2 is a cross-sectional view taken along line II-II in FIG. As shown in Figure 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, respectively. Of the frame material 31, a vertical frame portion 35 extending in the up-down 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 up-down direction.

[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, leaving the locking holes 36 that open forward in the vertical frame portions 35 exposed. Each of the panels 32, 33 in this embodiment preferably has light-blocking 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 of the panels 32, 33 may also be made of a light-transmitting material such as glass or acrylic resin.

[0023] As shown in Figure 1, entrance / exit unit 23 is disposed within the left opening of frame unit 21. Entrance / exit unit 23 is a so-called single sliding door. Specifically, entrance / exit unit 23 has a sash 40 fixed along the inner peripheral edge of the left opening of frame unit 21, and a fixed door 41 and a sliding door 42 attached to the sash 40.

[0024] The fixed door 41 is disposed at the front of 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 area defined by the fixed door 41 and the sash 40 forms an entrance / exit 43 that connects the inside and outside of the booth main body 13. The sliding door 42 is configured to be able to open and close the entrance / exit 43. In this embodiment, the sliding door 42 is supported by the sash 40 so as to be able to slide back and forth. When the sliding door 42 is in the open position (a position where it overlaps with the fixed door 41), people can enter and exit the booth 1 from the inside and outside of the booth main body 13 through the entrance / exit 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-blocking properties. The entrance / exit unit 23 is not limited to a single sliding door, and can be modified as appropriate, such as a double sliding door, a hinged door, or a folding door. Furthermore, in this embodiment, the booth body 13 has the left opening of the frame unit 21 as the entrance / exit 43, but this configuration is not limited thereto. 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 thereto. In a plan view, the booth body 13 may have a closed area formed by connecting adjacent support bodies 25.

[0026] The ceiling unit 24 has a bridging portion 45 that bridges between the left-right opposing portions of the beams 26 described above. A plurality of bridging 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 adjacent bridging portions 45. However, the ceiling unit 24 may completely separate the external space and the internal space S. Furthermore, a floor material unit may be separately provided on the floor surface F of the booth body 13.

[0027] <Lift-top fixture 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 has 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 columns 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. Note that each of the pair of legs 51 has the same configuration. Therefore, the following explanation will be given using the leg 51 disposed in the front left part of the booth body 13 as an example.

[0028] The leg bracket 55 is formed in a square cylindrical shape extending vertically along the support column main body 25 in the left front portion within the booth main body 13. The leg bracket 55 is equipped with a locking claw (not shown) that protrudes 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 top fixture 11 is fixed to the booth main body 13 via the leg bracket 55. However, the lifting top fixture 11 does not have to be connected to the booth main body 13.

[0029] The lifting unit 56 is configured to be extendable and retractable in the vertical direction. Specifically, the lifting unit 56 includes a plurality of rectangular tubes with different outer shapes in a plan view. The lifting unit 56 is configured by inserting a rectangular tube with a smaller outer shape in a plan view, among the rectangular tubes described above, inside a rectangular tube with a larger outer shape in a plan view. The lifting unit 56 is configured to be extendable and retractable in the vertical direction by the operation of a drive mechanism (not shown) causing the rectangular tubes to move relative to each other 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 plan view) housed in the leg bracket 55 described above.

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

[0031] The top plate 52 spans 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-to-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-to-rear direction. This makes it easier to ensure space below the top plate 52.

[0032] The top plate 52 has a work surface 52a facing upward. The work surface 52a is a flat surface perpendicular to the vertical direction. The top plate 52 is configured to be movable in the vertical direction in accordance with the extension and contraction movement of the lifting unit 56. As a result, the work surface 52a of the top plate 52 is configured to be able to change its height 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 taken along line VV in FIG. As shown in Fig. 5, the top plate 52 is trapezoidal in plan view. Specifically, the front edge of the top plate 52 extends linearly in the left-right direction. Both left and right end edges of the top plate 52 extend linearly in the front-rear direction. The shape of the top plate 52 in plan view can be changed as needed, such as to a rectangular shape or a semicircular shape.

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

[0035] An operating section 56a of the lifting unit 56 is disposed on the underside of the tabletop 52, in a portion located closer to the linearly extending section 58. In this embodiment, the operating section 56a is disposed on the right side of the underside of the tabletop 52.

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

[0037] <Chair 12> As shown in Figures 3 and 4, chair 12 faces liftable tabletop fixture 11 in the front-to-rear direction. Chair 12 is arranged along rear wall unit 22A within booth main body 13. Chair 12 in this embodiment can be used by a user in both a seated position (see Figure 4) and a standing position (see Figure 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. 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 of 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 22 A. The length of the mounting plate 65 in the left-right direction is equal to that of the rear wall unit 22 A. 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 make up the rear wall unit 22A. This allows the horizontal frame 61 to be fixed to the support main body 25 via the rear wall unit 22A. Note that the horizontal frame 61 may also be configured to be fixed directly to the support main body 25. Furthermore, the horizontal frame 61 is not limited to being locked via the locking portions 66, and can be secured by appropriate modifications such as screw fastening or welding.

[0040] The backrest brackets 62 are respectively fastened to the fastening holes 36 located above the horizontal frames 61 (fastening portions 66) in the vertical frame portions 35 constituting the rear wall unit 22A. In this embodiment, multiple pairs (for example, two pairs) of left and right backrest brackets 62 are attached at intervals 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 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 horizontal frame 61, for example, by 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 connecting mechanism 74, a biasing member 75, and a cover member .

[0043] <Base 71> The base 71 is attached to the horizontal frame 61 in 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 length of the base 71 in the left-right direction is shorter than the length of the horizontal frame 61 (the distance between adjacent support main bodies 25 in the left-right direction). The base 71 is formed in a C-shape that opens forward in a plan view. Specifically, the base 71 includes a rear panel 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-to-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 support main body 25 via the horizontal frames 61 and the vertical frame portions 35. However, the attachment method of the rear plate 81 can be changed as appropriate.

[0045] As shown in Figures 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 panel 81. The lower surface of the rear panel 81 is in contact with the floor F via an adjuster. The upper surface of the sidewall member 82 forms an inclined surface 82a that extends downward toward the front. In this embodiment, the entire upper surface of the sidewall member 82 forms the inclined surface 82a. However, the upper surface of the sidewall member 82 may be curved or stepped, or may be a flat surface perpendicular to the up-down direction, as long as it does not interfere with the seat 73.

[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 plate-shaped with its thickness in the front-to-rear direction, and is longer in the left-to-right direction than the base 71.

[0047] The backrest 72 is fixed to the backrest bracket 62 described above with screws or the like. As a result, the backrest 72 is spanned between the support pillar bodies 25 via the vertical frame portion 35 of the rear wall unit 22A. Meanwhile, the left side (the side facing the entrance 43) 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 from the same material as the decorative cover 63 described above. The backrest 72 may also be configured to be located only above the base 71.

[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 seated position (see FIG. 4: first position) in which the seat surface 73a faces upward, and an upright position (see the dashed line in FIG. 3: second position) in which the seat surface 73a faces forward. In the following explanation, unless otherwise specified, the state in which the seat 73 is in the seated position will be described as an example. In addition, in the seated position, the front side of the seat 73 may be referred to as the first side, and the rear side may be referred to as the second side.

[0049] FIG. 8 is a cross-sectional view showing the chair 12 in a seated position corresponding to the line VIII-VIII in FIG. As shown in Figure 8, seat 73 has the same length in the left-right direction as base 71 and has a triangular appearance in side view. Seat 73 is constructed with a framework made of plywood or the like covered with cushioning and upholstery. Specifically, seat 73 is thickest in the portion closer to the front of the center in the front-to-rear direction (hereinafter referred to as thickest portion 90), and gradually becomes thinner from thickest portion 90 toward both sides in the front-to-rear direction. Seat 73 comprises a main portion 91 and side portions 94.

[0050] The main portion 91 is formed like a plate 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. The first side end surface 91a of the main portion 91 extends rearward (to the second side in the front-to-rear direction) as it extends downward. On the other hand, the second side end surface 91b of the main portion 91 extends rearward as it extends downward.

[0051] In the plan view shown in FIG. 5 , the front edge of the main portion 91 extends linearly in the left-right direction. Therefore, the front edge of the main portion 91 extends parallel to the linear extension portion 58 of the top plate 52. In the illustrated example, the left-right length of the seat 73 is slightly shorter than the linear extension portion 58 of the top plate 52. However, the lengths of the base 71, seat 73, and top plate 52 can be changed as appropriate. By setting the left-right lengths of the base 71 and seat 73 to be equal to or shorter than the length of the linear extension portion 58, an entrance / exit space S1, where no furniture is installed, is formed around the entrance / exit 43 in the internal space S of the booth main body 13. The entrance / exit space S1 can be used for entering and exiting the booth main 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 of 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. Furthermore, the front end portion of the main portion 91 overlaps with the rear end portion of the table top 52 in a plan view. In other words, the front end edge of the main portion 91 is located forward of the rear end edge of the table top 52. However, the front end edge of the main portion 91 may be located at the same position as the rear end edge of the table top 52 or rearward.

[0053] 8, the side portions 94 are provided at both left and right ends of the main portion 91, respectively, over the entire length in the front-rear direction. The outer surfaces of the side portions 94 are arranged flush with the outer surfaces of the side wall members 82 (at positions where they overlap in a plan view). Below the main portion 91, the space surrounded by the side portions 94 forms a recess 98 that opens downward and toward both the front-rear direction and the rear.

[0054] The side portion 94 is formed with a first side clearance portion 95 and a second side clearance 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 relief portion 95 is formed by opening forward and downward from the front edge of the side portion 94 to the thickest portion 90. An edge portion 95a of the first side relief portion 95 slopes rearward as it extends downward. The second side relief portion 96 is formed by opening rearward and downward from the rear edge of the side portion 94 to the thickest portion 90. An edge portion 96a of the second side relief portion 96 slopes 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] FIG. 9 is a cross-sectional view showing the chair 12 in the standing position, taken along line VIII-VIII in FIG. 9, in the standing position, the edge 95a of the side portion 94 extends along the inclined surface 82a of the side portion 94. In the example shown, 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] <Connection Mechanism 74> 8 and 9, the connection mechanism 74 includes a link mechanism 120, a connecting portion 121, a first stopper 122, and a second stopper 123. A pair of link mechanisms 120 are provided on the left and right sides inside the base portion 71. In the following explanation, one of the link mechanisms 120 will be described as an example. The link mechanism 120 includes a slider 124 , a fixed link 125 , a first rotating link 126 , a second rotating link 127 , and a third rotating link 128 .

[0058] As shown in Figures 2 and 8, the slider 124 is supported on the inner surface (the surface facing inward in the left-right direction) of the sidewall member 82 so as to be able to move up and down. Specifically, a guide 130 is provided on the inner surface of the sidewall member 82. The guide 130 is formed in the shape of a plate extending in the up-down direction. As shown in Figure 2, the guide 130 has a rail 131 that protrudes inward in the left-right direction. The rail 131 is configured with a pair of L-shaped protrusions that extend in the up-down direction in a plan view. The inner side of the rail 131 is formed in the shape of a dovetail groove in a plan view.

[0059] The slider 124 includes a slide plate 135 and a roller 136 . The slide plate 135 is formed in a plate shape with its thickness in the left-right direction. The slide plate 135 is disposed inside the guide 130 in the left-right direction and along the guide 130 in the up-down direction. The rollers 136 protrude outward in the left-right direction from the slide plate 135. The rollers 136 are supported by the slide plate 135 so as to be rotatable about axes along the left-right direction. The rollers 136 are housed inside the rails 131. The slider 124 moves up and down while the rollers 136 rotate due to contact between the outer circumferential surfaces of the rollers 136 and the inner surface of the rails 131. Note that the slider 124 only needs to be supported by the guides 130 so as to be able to move up and down, and is not limited to a combination of the rails 131 and the rollers 136. For example, the slider 124 may be supported by a combination of a protrusion and a groove or an elongated hole, or a combination of a roller and an elongated hole.

[0060] 8, the fixed link 125 is fixed to the lower surface of the main portion 91. The fixed link 125 extends in the front-rear direction. The first rotating link 126 connects the fixed link 125 and the rear panel 81. Specifically, one end of the first rotating link 126 is rotatably connected to the front part of the fixed link 125 via a first pin 140 extending in the left-right direction. The other end of the first rotating link 126 is rotatably connected to a link stay 139 provided on the rear panel 81 via a second pin 141 extending in the left-right direction.

[0061] The second rotating link 127 connects the fixed link 125 and the slider 124. The second rotating link 127 is shorter than the first rotating link 126. One end of the second rotating link 127 is rotatably connected to the rear part of the fixed link 125 via a third pin 142 extending in the left-right direction. The other end of the second rotating link 127 is rotatably connected to the upper end of the slide plate 135 via a fourth pin 143 extending in the left-right direction. In this embodiment, the fourth pin 143 is located above and rearward of the second pin 141.

[0062] The third pivot link 128 connects the first pivot link 126 and the slider 124. One end of the third pivot link 128 is pivotally connected to a portion of the first pivot link 126 located closer to the other end thereof via a fifth pin 144 extending in the left-right direction. The other end of the third pivot link 128, together with the second pivot link 127 described above, is pivotally connected to the slide plate 135 via a fourth pin 143. However, the third pivot link 128 does not need to be connected coaxially with the second pivot link 127 as long as it is pivotally connected to the slider 124.

[0063] 7, the connecting portion 121 extends in the left-right direction along the rear plate 81 behind the link mechanism 120. The connecting portion 121 bridges between the upper ends of the sliders 124 (slide plates 135) of the pair of link mechanisms 120.

[0064] When the seat 73 is in the seating position shown in FIG. 8, the first pivot link 126 and the second pivot link 127 face obliquely upward and forward, and the third pivot link 128 faces obliquely upward and rearward.

[0065] FIG. 10 is an explanatory diagram of the operation of the seat 73. As shown in FIG. 10, when the seat 73 moves from the seated position to the standing position, the link mechanism 120 rotates the rotary links 126-128 around the pins 140-144, causing the slider 124 to move upward. As a result, the second end of the seat 73 moves upward while the first end moves rearward, resulting in the standing position in which the seat surface 73a faces forward, as shown in FIG. 9. In this state, the rotary links 126-128 extend vertically with some portions overlapping each other when viewed from the left and right. The upper end of the slider 124 protrudes from the guide 130. In the standing position, the first rotary link 126 is tilted slightly forward in the vertical direction. Meanwhile, in the standing position, the second rotary link 127 is tilted slightly forward in the vertical direction.

[0066] The first stopper 122 protrudes forward from the rear panel 81. The first stopper 122 restricts the rearward movement of the first rotating link 126. Specifically, when the seat 73 is in the upright position shown in FIG. 9, the first rotating link 126 approaches the first stopper 122 from the front. Note that the first rotating link 126 may abut against the first stopper 122 from the front when the seat 73 is in the upright position.

[0067] As shown in FIG. 8 , the second stopper 123 is provided on a portion of the rear panel 81 that is located laterally inward of the first stopper 122. The second stopper 123 is crank-shaped in side view. The second stopper 123 is disposed with its lower end fixed to the rear panel 81 and its upper end spaced apart from the rear panel 81. When the seat 73 is in the seating position, the connecting portion 121 enters from above into a gap between the upper end of the second stopper 123 and the rear panel 81. As a result, the forward movement of the connecting portion 121 is restricted by the upper end of the second stopper 123, and the downward movement of the connecting portion 121 is restricted by a connecting portion that connects the upper and lower ends of the second stopper 123. Note that the second stopper 123 may restrict the downward and forward movement of the connecting portion 121 using separate members.

[0068] 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 panel 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 portion 91 so as to be rotatable about an axis along the left-right direction. Specifically, when the seat 73 is in the seating position, the upper end of the biasing member 75 is connected rearward of the first pin 140. In the illustrated example, the upper end of the biasing member 75 is connected to the main portion 91 between the first pin 140 and the second pin 141 in the front-rear direction. As a result, the biasing member 75 biases the seat 73 toward the upright position and also biases the seat 73 forward. Note that the biasing member 75 is not limited to a gas spring and can be appropriately changed, for example, to a torsion spring. Furthermore, the biasing member 75 is not an essential component.

[0069] 3, 4, and 7, at least a portion of the connection mechanism 74 and the biasing member 75 is surrounded on 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. On the other hand, 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). This makes at least a portion of the connection mechanism 74 and the biasing member 75 invisible in a side view.

[0070] <Cover member 76> As shown in FIGS. 7 to 9, the cover member 76 includes a non-stretchable portion 160 and a stretchable portion 161. As shown in FIGS. The non-extendable portion 160 is a plate material made of, for example, metal, etc. The non-extendable portion 160 spans between the pair of first pivot links 126 in the link mechanism 120. The non-extendable portion 160 extends over approximately the entire length of the first pivot links 126, and covers the connection mechanism 74 and the biasing member 75 from the front.

[0071] As shown in FIG. 7 , the stretchable portion 161 is formed in a band shape using, for example, a woven fabric. The stretchable portion 161 is stretchable in both the vertical and horizontal directions. The stretchable portion 161 has a joint 165 at a portion located behind the connection mechanism 74 when the seat 73 is in the upright position. The joint 165 is a portion of the stretchable portion 161 where both ends of the band are joined together using a hook-and-loop fastener or the like. In this embodiment, the joint 165 extends over the entire length of the stretchable portion 161 in the upright direction when the seat 73 is in the upright position. As a result, the stretchable portion 161 is formed in a cylindrical shape that surrounds the connection mechanism 74 and the biasing member 75 between the base 71 and the seat 73.

[0072] Of the upper edge of the expandable portion 161, the portions located rearward and on both the left and right sides of the link mechanism 120 are joined to the underside of the main portion 91 by, for example, a hook-and-loop fastener. Of the lower edge of the expandable portion 161, the portions located rearward and on both the left and right sides of the link mechanism 120 are joined to the front surface of the rear panel 81 by, for example, a hook-and-loop fastener. On the other hand, the portion of the extension / contraction section 161 that is located in front of the link mechanism 120 is fixed to the first rotating link 126 together with the non-extension / contraction section 160. However, the method of fixing the cover member 76 can be changed as appropriate.

[0073] [How to use Booth 1] Next, we will explain how to use the booth 1 described above. The following explanation will mainly focus on how to use the booth in the standing position and how to use the booth in the sitting position. Note that the following explanation will be given assuming that the seat 73 is in the standing position due to the biasing force of the biasing member 75, and the top panel 52 is set to the height used when the seat 73 is in the standing position, as the initial state. As shown in Figure 1, first, the sliding door 42 is moved to the open position, and the person enters the booth body 13 through the entrance 43. Then, the person enters between the liftable tabletop fixture 11 and the chair 12, and faces the liftable tabletop fixture 11.

[0074] As shown in Figure 3, when seat 73 is in the standing position, 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 seat 73, their buttocks are supported by the second side end of seat 73 (seated position). This allows the user to sit on seat 73 in an upright position and work facing lift-top furniture 11.

[0075] FIG. 11 is a cross-sectional view showing the chair 12 in a seated position corresponding to the line VIII-VIII in FIG. As shown in FIG. 11 , when a user sits on the seat 73 in the standing position, the user's weight acts on the seat 73 diagonally downward and rearward. This causes the pivot links 126-128 to pivot about the pins 140-144. This places the seat 73 in a seated position tilted backward relative to the standing position. In the seated position, the second side end of the seat 73 abuts against the backrest 72, or the first pivot link 126 abuts against the first stopper 122, restricting rearward movement of the seat 73. In addition, in the seated position, the first pivot link 126 is perpendicular to the floor surface F or slightly tilted backward. Therefore, even if a downward load acts on the seat 73, the first pivot link 126 is less likely to pivot forward. As a result, the seat 73 is prevented from unexpectedly moving from the seated position to the standing position and then to the sitting position.

[0076] Next, when using the seat 73 in the seated position, the second side end is pushed downward with the seat 73 in the upright position shown in Fig. 9. Then, as shown in Fig. 10, the pivot links 126-128 pivot about the pins 140-144, and the slider 124 moves downward. As a result, the seat 73 moves toward the seated position against 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.

[0077] 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.

[0078] Furthermore, the user can set the height of the tabletop 52 to suit the seated posture by operating the operating unit 56a. Specifically, when the operating unit 56a is operated, the lifting unit 56 contracts, causing the tabletop 52 to lower. This allows the user to work on the tabletop 52 while seated on the seat 73.

[0079] Here, in the process of the seat 73 moving from the standing position to the sitting position, the first pivot link 126 and the second pivot link 127 of the link mechanism 120 rotate so that they lean forward, while the third pivot link 128 rotates rearward. As a result, the distance between the first pivot link 126 and the second pivot link 127 increases in side view. In other words, as the seat 73 moves between the sitting position and the standing position, the change in the outline (displacement) of the link mechanism 120 in side view is greatest. Then, the expandable portion 161 expands and contracts in response to the displacement of the link mechanism 120, and the seat 73 moves between the sitting position and the standing position with the connection mechanism 74 always covered by the cover member 76.

[0080] If 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, as the rotary links 126-128 rotate about the pins 140-143, the slider 124 moves upward, and the second side end of the seat 73 moves upward while the first side end moves backward. As a result, the seat 73 stands up while avoiding the rear edge of the top plate 52, and assumes the standing position with the seat surface 73a facing forward.

[0081] In this manner, in this embodiment, the cover member 76 that surrounds the entire periphery of the link mechanism (support mechanism) 120 between the base 71 and the seat 73 is provided. This configuration can prevent articles and the like from passing between the base 71 and the seat 73 and reaching the link mechanism 120. This can prevent articles and the like from getting caught in the seat 73 or the link mechanism 120. Moreover, in this embodiment, the cover member 76 is configured to include the expansion and contraction portion 161 that expands and contracts in response to the displacement of the link mechanism 120. With this configuration, the expandable portion 161 expands and contracts in response to the displacement of the link mechanism 120. This prevents the cover member 76 from interfering with the displacement of the link mechanism 120, allowing the seat 73 to move smoothly between the seated position and the standing position.

[0082] In this embodiment, the expandable portion 161 covers the link mechanism 120 from the outside in the left-right direction. With this configuration, when the seat 73 moves between the seated position and the standing position, the link mechanism 120 undergoes the greatest displacement in a side view. Therefore, by covering the link mechanism 120 from the outside in the left-right direction with the expandable portion 161, it is possible to more reliably prevent the cover member 76 from interfering with the displacement of the link mechanism 120.

[0083] In this embodiment, the extendable portion 161 is configured to cover the link mechanism 120 from behind when the seat 73 is in the upright position. According to this configuration, the distance between the seat 73 and the base 71 expands and contracts as the seat 73 moves between the seated position and the standing position. Therefore, by covering the link mechanism 120 from behind with the expandable portion 161, it is possible to more reliably prevent the cover member 76 from interfering with the displacement of the link mechanism 120. It is also possible to prevent objects, etc. that fall between the upper end of the base 71 and the seat 73 from reaching the link mechanism 120. This makes it possible to prevent objects, etc. from getting caught in the seat 73 or the link mechanism 120.

[0084] In this embodiment, both ends of the band-shaped body constituting the extension section 161 are joined in the vertical direction at a portion located behind the link mechanism 120 when the seat 73 is in the upright position. According to this configuration, by joining the band-shaped body behind the seat 73, the joint 165 is less visible to the user. As a result, the aesthetic appearance of the chair 12 can be improved. Additionally, at the rear of the seat 73, the extension portion 161 does not stretch much in the left-right direction, so the joint portion 165 is less likely to be pulled in the left-right direction. As a result, the joint portion 165 can be prevented from breaking or the like for a long period of time.

[0085] In this embodiment, the cover member 76 is configured to include a non-stretchable portion 160 that covers the link mechanism 120 from the front. According to this configuration, the link mechanism 120 can be protected from the entry of the user's feet, objects, etc. from the front of the chair 12.

[0086] The booth 1 of this embodiment is provided with the chairs 12 described above, so that users can use the booth 1 comfortably.

[0087] (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 appended claims. In the above-described embodiment, the fixture according to the present invention is applied to chair 12, but the present invention is not limited to this configuration. The fixture may be, for example, a desk or shelf, as long as the load-bearing part (for example, a top plate) is configured to move between a first position and a second position. In the above embodiment, a configuration has been described in which chairs 12 and liftable tabletop fixtures 11 are installed inside booth main body 13, but this configuration is not limiting. Chairs 12 do not have to be installed inside booth main body 13, and do not have to be installed in combination with liftable tabletop fixtures 11. Chairs 12 may also be sofas, sofa beds, etc.

[0088] In the above-described embodiment, the case where the operation unit is arranged on the right side of the underside of the top plate 52 has been described, but the present invention is not limited to this configuration. For example, the operation unit may be arranged on the underside of the top plate 52 on the side closer to the entrance 43 (for example, near the inclined portion 59).

[0089] In the above-described embodiment, the link mechanism 120 has been described as an example of the support mechanism, but the support mechanism may be other than the link mechanism 120, and for example, the load support part may be supported by a slide groove or the like so that it can move between the first position and the second position. Also, it is sufficient that the seat 73 has at least an upward-facing component in the first position (seated position), and at least an upward-facing component in the second position (standing position). In the above-described embodiment, a configuration in which the expandable portion 161 surrounds the entire periphery of the link mechanism 120 has been described, but this configuration is not limited to this. As long as the entire periphery of the link mechanism 120 is surrounded by the cover member, for example, the entire periphery of the link mechanism 120 may be surrounded by a combination of the non-expandable portion 160 and the expandable portion 161. Furthermore, as long as the cover member includes at least the expandable portion 161, the cover member may not have the non-expandable portion 160. In the above-described embodiment, the stretchable portion is configured to ensure stretchability by using woven fabric, but this configuration is not limiting. The stretchable portion may be formed in a bellows shape or may contain a rubber material. Furthermore, the non-stretchable portion and the stretchable portion may be formed from the same material or different materials. By using different materials, it is possible to select a material with excellent stretchability for the stretchable portion while using a strong material with low stretchability for the non-stretchable portion to protect the link mechanism. In the above-described embodiment, the base 71 is configured to include the rear panel 81 and the side wall member 82, but the configuration is not limited to this. The base may be, for example, the support column body 25 or panel unit 22 of the booth body 13, or a wall that constitutes the office space.

[0090] In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
