Description

Technical Field

[0001] The present invention relates to a chair.

Background Art

[0002] Chairs used in facilities such as conference rooms, theaters, and halls are arranged with identification information such as seat numbers in order to recognize the location of the seats. In particular, among various facilities, in a facility used for multiple purposes (hereinafter referred to as a multi-purpose facility), it is necessary to change the layout of the chairs according to the content of the event. Therefore, the chairs adopted in multi-purpose facilities are configured to be movable so that they can be stored in a stacked state in, for example, a backyard when not in use and can be laid out at a predetermined position according to the event or use when in use.

[0003] However, when the identification information attached to each chair is fixed, there is a problem that the layout work of each chair is complicated for the following reasons, for example. First, chairs are not always stored in an organized state for each piece of identification information when not in use. Therefore, when rearranging the chairs stored in the backyard or the like, it is necessary to search for the chairs with the identification information corresponding to the installation position and to compare the identification information with the layout. Second, in multi-purpose facilities, the layout and identification information of the chairs may differ depending on the event or use. Therefore, when the identification information is fixed, there may be a case where chairs with unused identification information are stored closer to the front than chairs with the identification information to be used.

[0004] Here, for example, Patent Document 1 below discloses a configuration in which a display plate is loosely fitted in an opening groove of a chair and a soft magnetic body is built into the display plate. According to this configuration, the display plate can be removed from the opening groove by a removing means having a built-in magnet.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the above-described conventional technology, since it is necessary to attach and detach the display board every time the layout is changed, there is still room for improvement from the viewpoint of workability.

[0007] The present invention provides a chair capable of improving workability at the time of layout change or the like.

Means for Solving the Problems

[0008] In order to solve the above problems, the present invention adopts the following aspects. (1) A chair according to an aspect of the present invention includes a chair body having a pedestal surface facing a first side in a first direction and having a recess formed to open to the first side in the first direction, and a plurality of display members formed such that a thickness in the first direction is less than a depth of the recess in the first direction and arranged to be stackable in the recess while being supported by the pedestal surface. Among the plurality of display members, the display member arranged on a second side in the first direction and provided with first identification information is defined as a first display member, and the display member arranged on the first side in the first direction with respect to the first display member and provided with second identification information is defined as a second display member. In a state where the plurality of display members are stacked in the recess, the second display member covers the first display member so that at least the first identification information is not exposed to the outside through the opening of the recess.

[0009] According to this aspect, in a state where a plurality of display members are stacked in the recess, by covering the first display member with the second display member so that at least the first identification information is not exposed to the outside through the opening of the recess, new identification information can be displayed on the chair without removing the first display member. That is, when changing the layout of the chair or the like, a chair with new identification information can be provided simply by stacking the second display member on the first display member. Thereby, since it is not necessary to manage the chair based on the originally attached identification information, the layout of the chair can be easily changed. In this case, unlike the conventional method, it is not necessary to attach and detach the display plate every time the layout is changed, so the workability can be improved.

[0010] (2) In the chair according to the aspect (1) above, it is preferable that the thickness of the display member in the first direction is formed to be half or less of the depth of the recess in the first direction. According to this aspect, even if the display members are stacked, it is possible to suppress the second display member from bulging out of the recess. Thereby, when touching the vicinity of the recess during sitting or when changing the layout, it is possible to prevent hands or the like from touching the display member. This can suppress unexpected detachment of the display member and improve the usability and workability.

[0011] (3) In the chair according to any one of the aspects (1) or (2) above, in a state where a plurality of the display members are stacked in the recess, it is preferable that the surface of the first display member facing the first side in the first direction and the surface of the second display member facing the second side in the first direction are joined. According to this aspect, for example, compared with the case where a structure in which a plurality of display members can be stacked is formed in the chair body, the chair body can be provided at a low cost.

[0012] (4) In the chair according to the aspect (3) above, it is preferable that the plurality of display members each have an adhesive layer on the surface facing the second side in the first direction. According to this aspect, the first display member and the pedestal surface, as well as the first display member and the second display member, can be joined via an adhesive layer. As a result, a seal-shaped display member having a base material such as paper or resin can be used, and the cost of the display member can be reduced.

[0013] (5) In the chair according to the aspect of (3) or (4) above, it is preferable that at least a part of the pedestal surface is subjected to a roughening process. According to this aspect, the contact area between the first display member and the pedestal surface is reduced, and the first display member is easily peeled off from the pedestal surface. As a result, even when a plurality of display members are laminated on the pedestal surface, the plurality of display members can be easily removed together from the concave portion.

[0014] (6) In the chair according to any one of the aspects (1) to (5) above, the chair body includes a display support portion in which the concave portion is formed, and the display support portion penetrates the display support portion in the first direction so as to open at the pedestal surface, and it is preferable that a through hole having a smaller diameter than the display member is formed when viewed from the first direction. According to this aspect, by inserting a tool or the like into the concave portion through the through hole from the space on the second side in the first direction with respect to the display support portion, the first display member can be easily removed from the pedestal surface. As a result, even when a plurality of display members are laminated on the pedestal surface, the plurality of display members can be easily removed together from the concave portion.

Effect of the Invention

[0015] According to each of the above aspects, the workability at the time of layout change or the like can be improved.

Mode for Carrying Out the Invention

[0017] Next, embodiments of the present invention will be described with reference to the drawings. In the embodiments and modifications described below, corresponding components may be denoted by the same reference numerals and the description thereof may be omitted. In the following description, expressions indicating relative or absolute arrangements such as "parallel", "orthogonal", "center", "coaxial", etc. not only strictly represent such arrangements, but also represent states in which they are relatively displaced with tolerances and angles or distances that can obtain the same function. Further, in the present embodiment, "opposite" includes not only the case where the orthogonal directions (normal directions) of two surfaces coincide with each other, but also the case where the orthogonal directions intersect each other.

[0018] (First Embodiment) FIG. 1 is a perspective view of the chair 1 as seen from the front. FIG. 2 is a perspective view of the chair 1 as seen from below. The chair 1 shown in FIGS. 1 and 2 is a portable (carryable) chair 1 installed, for example, in a multipurpose facility. The chairs 1 are arranged in a predetermined layout in the multipurpose facility during use. On the other hand, the chairs 1 are stored in a stacked state, for example, in a backyard or the like when not in use. Note that stacking means that a plurality of chairs 1 are stored in a state where they are stacked in the vertical direction (first direction). In the following description, the directions such as front, back, up, down, left, and right are the same as the directions of a person (seated person) sitting in the regular posture on the chair 1. In this case, the arrow UP in the figure indicates upward, the arrow FR indicates forward, and LH indicates left.

[0019] The chair 1 includes a chair body 5 and a display member 120. The chair body 5 is a so-called nude shell type chair body 5 in which the backrest 2 and the seat 3 do not have cushioning materials. Specifically, the chair body 5 is configured such that the backrest 2 and the seat 3 are supported by a support structure 4. Note that at least one of the backrest 2 and the seat 3 of the chair body 5 may have a cushioning material.

[0020] <Support structure 4> The support structure 4 includes a pair of left and right legs 10, a rear connecting rod 11, a front frame 12, and side frames 13. Each leg 10 has a configuration in which a pipe material made of metal or the like is bent into a trapezoidal frame shape in a side view. Specifically, the leg 10 includes a front leg 21, a rear leg 22, a lower connecting rod 23, an upper connecting rod 24, and a backrest support portion 25.

[0021] The front leg 21 constitutes the front portion of the leg 10. The front leg 21 extends in the vertical direction in a state where it is gradually inclined forward as it goes downward. The lower connecting rod 23 extends rearward from the lower end portion of the front leg 21. The lower connecting rod 23 is grounded to the floor surface F (see FIG. 1) via a grounding cap 26. The rear leg 22 constitutes the rear portion of the leg 10. The rear leg 22 extends upward from the rear end portion of the lower connecting rod 23. In the present embodiment, the rear leg 22 is inclined forward as it goes upward. The upper connecting rod 24 extends rearward from the upper end of the front leg 21. The rear end of the upper connecting rod 24 overlaps with the upper end of the rear leg 22 in side view. In the illustrated example, the rear end of the upper connecting rod 24 is disposed inside the upper end of the rear leg 22 in the left-right direction.

[0022] The backrest support portion 25 is configured such that a portion bent upward from the rear end of the upper connecting rod 24 and a portion protruding upward from the upper end of the rear leg 22 among the pipe members constituting the leg body 10 are joined together by welding or the like.

[0023] As shown in FIG. 2, the rear connecting rod 11 bridges the rear portions of the upper connecting rods 24 in each leg body 10. The rear connecting rod 11 has an arc shape convex rearward in plan view. Both left and right ends of the rear connecting rod 11 are joined to the corresponding upper connecting rods 24 by welding or the like.

[0024] The front frame 12 is configured such that a plate material such as metal extends along the left-right direction. The front frame 12 bridges the corners formed by the upper connecting rod 24 and the front leg 21 in each leg body 10. Both left and right ends of the front frame 12 are joined to the corresponding corners by welding or the like. In the present embodiment, the front frame 12 extends downward as it goes forward following the corner formed by the upper connecting rod 24 and the front leg 21.

[0025] The side frame 13 projects inward in the left-right direction (toward the center of the chair body 5) from the upper connecting rod 24 in each leg body 10. The side frame 13 is formed of a plate material such as metal and extends in the front-rear direction with the up-down direction as the thickness direction. In the present embodiment, the rear connecting rod 11, the front frame 12, the side frame 13, and the upper connecting rod 24 constitute a seat support portion 30 having a rectangular frame shape in plan view.

[0026] <Backrest 2> As shown in FIGS. 1 and 2, the backrest 2 is supported by a backrest support portion 25. The backrest 2 supports the waist and back of the seated person from behind. In the present embodiment, the backrest 2 is integrally formed by injection molding a resin material. Specifically, the backrest 2 includes a backrest main body 31, a frame portion 32, and a leg housing portion 33.

[0027] The backrest main body 31 constitutes the front view outer shape of the backrest 2. Specifically, the backrest main body 31 has an arc shape that is convex rearward in plan view and an arc shape that is convex forward in side view. A plurality of through holes 31a are formed in the backrest main body 31. The through holes 31a are arranged at intervals in the vertical and horizontal directions. Further, at the upper part of the backrest main body 31, a handle hole 31b is formed at the center in the left-right direction. The handle hole 31b penetrates the backrest main body 31 in the front-rear direction, and the front view outer shape is formed larger than the through hole 31a. The handle hole 31b allows an operator's hand to be inserted, for example, when carrying the chair 1.

[0028] The frame portion 32 extends rearward from the entire outer peripheral edge of the backrest main body 31 so as to surround the periphery of the backrest main body 31. Therefore, an open space S1 (a space on the second side in the first direction with respect to the display support portion) that is open rearward is defined by the frame portion 32 and the backrest main body 31. Specifically, the frame portion 32 includes an upper frame portion 32a, a pair of side frame portions 32b, and a lower frame portion 32c. The upper frame portion 32a protrudes rearward from the upper end edge of the backrest main body 31. The upper frame portion 32a extends over the entire length in the left-right direction at the upper end edge of the backrest main body 31. In the illustrated example, the upper frame portion 32a has a gradually increasing dimension in the front-rear direction (the amount of protrusion from the backrest main body 31) from both ends in the left-right direction toward the center. The lower surface of the upper frame portion 32a is exposed in the open space S1.

[0029] The side frame portions 32b protrude rearward from the left and right end edges of the backrest main body 31. The upper end edges of the respective side frame portions 32b are connected to the left and right ends of the upper frame portion 32a, respectively. As shown in FIG. 2, the lower frame portion 32c protrudes rearward from the lower edge of the backrest main body 31. It extends over the entire length in the left-right direction at the lower edge of the lower frame portion 32c. Both left and right end portions of the lower frame portion 32c are respectively connected to the lower end portions of the respective side frame portions 32b.

[0030] The leg accommodating portions 33 protrude rearward at both left and right end portions of the backrest main body 31. Each leg accommodating portion 33 opens downward. In each leg accommodating portion 33, the leaning support portion 25 is separately inserted. Thereby, the backrest 2 is supported by the support structure 4. Note that the backrest support portion 25 may be fixed to the backrest 2 by screws or the like in a state of being accommodated in the leg accommodating portion 33, or may be fixed to the backrest 2 by being press-fitted into the leg accommodating portion 33.

[0031] <Seat 3> As shown in FIGS. 1 and 2, the seat 3 is supported from below by the support structure 4. Specifically, the seat 3 includes a seat main body 51 and a connecting portion 52. The seat 3 is integrally formed by injection molding a resin material. The seat main body 51 is formed in a plate shape with the vertical direction as the thickness direction. The seat main body 51 supports the buttocks, thighs, etc. of the seated person from below during seating. Specifically, the seat main body 51 includes a main support portion 55, a front continuous portion 56, and a rear continuous portion 57.

[0032] The main support portion 55 covers the above-described seat support portion 30 from above. The main support portion 55 is formed in a rectangular shape in plan view. The main support portion 55 has a downwardly convex arc shape in a cross-sectional view orthogonal to the front-rear direction and in a cross-sectional view orthogonal to the left-right direction. Of the outer peripheral portion of the main support portion 55, both left and right end portions are close to or in contact with the upper connecting rod 24 in the vertical direction. Of the outer peripheral portion of the main support portion 55, the rear end portion is close to or in contact with the rear connecting rod 11 in the vertical direction.

[0033] The front continuous portion 56 is connected to the front edge of the main support portion 55. Specifically, the front continuous portion 56 extends while curving downward as it goes forward following the corner formed by the upper connecting rod 24 and the front leg 21 in a side view.

[0034] The rear continuous portion 57 is connected to the rear edge of the main support portion 55. Specifically, the front part of the rear continuous portion 57 extends while curving upward as it goes backward following the corner formed by the upper connecting rod 24 and the backrest support portion 25 in a side view. The rear part of the rear continuous portion 57 extends while inclining downward as it goes backward.

[0035] As shown in FIG. 2, a first rib 65 and a second rib 66 are formed on the lower surface (rear surface) of the rear continuous portion 57. The first rib 65 is arranged at intervals in the left - right direction at the central portion in the left - right direction of the rear continuous portion 57. The first rib 65 extends in the front - rear direction so as to straddle the front part and the rear part of the rear continuous portion 57. The second rib 66 extends in the left - right direction at the front part of the rear continuous portion 57. The front end portion of the first rib 65 is connected to the second rib 66. Note that the shape, pitch, etc. of each rib 65, 66 can be changed as appropriate.

[0036] The connecting portion 52 is a portion that connects the seat 3 to the support structure 4. The connecting portion 52 includes a side connecting portion 70 and a front connecting portion 71. The side connecting portion 70 is formed at both ends in the left - right direction on the lower surface of the main support portion 55. Specifically, the side connecting portion 70 extends in the front - rear direction at a position overlapping with the side frame 13 in a plan view on the lower surface of the main support portion 55. The side connecting portion 70 is connected to the side frame 13 by screws or the like. The front connecting portion 71 is formed at the front end on the lower surface of the main support portion 55. Specifically, the front connecting portion 71 extends in the left - right direction at a position overlapping with the front frame 12 in a plan view on the lower surface of the main support portion 55. The front connecting portion 71 is connected to the front frame 12 by screws or the like.

[0037] FIG. 3 is a cross-sectional view corresponding to line III-III in FIG. 1. FIG. 4 is a cross-sectional view corresponding to line IV-IV in FIG. 3. As shown in FIGS. 3 and 4, a back recess (recess) 100 is formed in an upper frame portion (display support portion) 32a of the backrest 2. The back recess 100 is for accommodating and holding a plurality of display members 120. The back recess 100 is formed in a bottomed shape that opens only upward at the central portion in the left-right direction in the upper frame portion 32a. Specifically, the inner surface of the back recess 100 includes a back bottom surface (pedestal surface) 100a and a back inner peripheral surface 100b.

[0038] The back bottom surface 100a constitutes the bottom surface of the back recess 100. The back bottom surface 100a is formed in a rectangular shape in a plan view with the left-right direction as the longitudinal direction and the front-back direction as the short-side direction. The entire area of the back bottom surface 100a is formed as a smooth surface facing upward (the first side in the first direction).

[0039] The back inner peripheral surface 100b extends upward from the outer peripheral edge of the back bottom surface 100a so as to surround the entire circumference of the back bottom surface 100a. The upper edge of the back inner peripheral surface 100b is continuous with the upper surface of the upper frame portion 32a. In the illustrated example, the boundary portion between the back inner peripheral surface 100b and the upper surface of the upper frame portion 32a is continuous via a chamfered portion such as a round chamfer. Therefore, the upper end portion of the back recess 100 gradually expands in plan view as it goes upward. Note that the back recess 100 may gradually expand in plan view as it goes upward over the entire length in the vertical direction, for example, by inclining the entire back inner peripheral surface 100b. Also, the back recess 100 may be open not only upward but also rearward or the like.

[0040] Of the upper frame portion 32a, a portion (hereinafter referred to as the back pedestal wall portion 101) located between the back bottom surface 100a and the lower surface of the upper frame portion 32a is formed with a back insertion hole (through hole) 101a. The back insertion hole 101a penetrates the back pedestal wall portion 101 in the vertical direction. The back insertion hole 101a is formed in a tapered shape in which the outer diameter gradually decreases as it goes upward. The upper end opening of the back insertion hole 101a opens on the back bottom surface 100a. On the other hand, the lower end opening of the back insertion hole 101a opens on the lower surface of the upper frame portion 32a, thereby opening into the open space S1. That is, the inside of the back recess 100 communicates with the open space S1 through each insertion hole 101a. Note that the back insertion hole 101a may have a uniform inner diameter.

[0041] As shown in FIG. 4, a plurality (for example, two) of back insertion holes 101a are formed in the back pedestal wall portion 101 at intervals in the left-right direction. In the illustrated example, each back insertion hole 101a is arranged to be distributed on both the left and right sides with respect to the center in the left-right direction on the back bottom surface 100a. In this case, the distance D1 (center distance) between each back insertion hole 101a is longer than the distance D2 between the insertion hole 101a located on one side in the left-right direction and one side edge in the left-right direction of the back bottom surface 100a, and the distance D3 between the insertion hole 101a located on the other side in the left-right direction and the other side edge in the left-right direction of the back bottom surface 100a. However, the number, position, etc. of each insertion hole 101a can be changed as appropriate.

[0042] FIG. 5 is a cross-sectional view corresponding to the line V-V in FIG. 1. FIG. 6 is a cross-sectional view corresponding to the line VI-VI in FIG. 5. As shown in FIGS. 5 and 6, in the seat 3, a seat-side recess (recess) 110 is formed in the rear-side continuous portion (display support portion) 57. The seat-side recess 110 is formed at the center in the left-right direction in the rear-side continuous portion 57 and is a bottomed recess that opens upward. In the present embodiment, the seat-side recess 110 opens obliquely upward to the front following the extending direction of the rear-side continuous portion 57. The seat-side recess 110 overlaps with the first rib 65 and the second rib 66 in a plan view. Note that the seat-side recess 110 has a configuration corresponding to the back-side recess 100. Therefore, hereinafter, regarding the configuration similar to the back-side recess 100 in the seat-side recess 110, the description will be appropriately omitted.

[0043] Similar to the back-side recess 100, the seat-side recess 110 has a seat-side bottom surface 110a and a seat-side inner peripheral surface 110b. The depth of the seat-side recess 110 is formed to be equal to the depth of the back-side recess 100. Note that the depth of the back-side recess 100 is the dimension of the back-side recess 100 in a direction orthogonal to the back-side bottom surface 100a, and the depth of the seat-side recess 110 is the dimension of the seat-side recess 110 in a direction orthogonal to the seat-side bottom surface 110a. Note that the dimensions of the back-side recess 100 and the seat-side recess 110 may be different from each other.

[0044] In the rear-side continuous portion 57, a portion (hereinafter referred to as a seat-side pedestal wall portion 111) located between the seat-side bottom surface 110a and the lower surface of the rear-side continuous portion 57 is formed with a seat-side insertion hole (through hole) 111a. The seat-side pedestal wall portion 111 is penetrated in the vertical direction. The upper end opening of the seat-side insertion hole 111a opens on the seat-side bottom surface 110a. On the other hand, the lower end opening of the seat-side insertion hole 111a opens on the lower surface of the rear-side continuous portion 57, thereby being opened to the lower space S2 of the seat 3 (the space on the second side in the first direction with respect to the display support portion). That is, the inside of the seat-side recess 110 communicates with the lower space S2 of the seat 3 through the seat-side insertion hole 111a. In the present embodiment, the seat-side insertion hole 111a is formed in a portion of the rear-side continuous portion 57 that is behind the second rib 66 and located between the adjacent first ribs 65. However, the relative positions of the respective seat-side insertion holes 111a and the ribs 65, 66 can be appropriately changed.

[0045] Here, a plurality of display members 120 can be stored in a stacked state in the back concave portion 100 and the seat-side concave portion 110. Hereinafter, taking the display member 120 provided in the back concave portion 100 as an example, the details of the display member 120 will be described.

[0046] FIG. 7 is a cross-sectional view corresponding to FIG. 4 showing a state in which three display members 120 are stacked. As shown in FIG. 7, the display member 120 of the present embodiment includes a lowermost-layer display member 120A, a first upper-layer display member 120B, and a second upper-layer display member 120C. Each of the display members 120A to 120C has the same configuration. Therefore, when it is not necessary to distinguish each of the display members 120A to 120C, it will simply be described as the display member 120.

[0047] The display member 120 is a seal (sticker) type display member 120. Specifically, the display member 120 has a configuration in which a base material and an adhesive layer are laminated. The base material has, for example, a single-layer structure or a laminated structure of paper or resin. On the base material, identification information for identifying the position (for example, row or column) of each chair 1 among a plurality of chairs 1 arranged in a multi-purpose facility, such as a seat number, is visibly attached. Note that a surface layer covering the base material may be provided on the surface of the base material.

[0048] The adhesive layer is provided on the back surface of the base material. The adhesive layer is, for example, a layer made of a pressure-sensitive adhesive that exhibits adhesiveness by applying only a slight pressure at room temperature for a short time without using a solvent or heat. As the pressure-sensitive adhesive, for example, an acrylic-based or silicone-based adhesive can be appropriately selected. Note that the adhesive layer may be formed over the entire back surface of the base material, or may be formed in an arbitrary range on the back surface of the base material.

[0049] The display member 120 is formed in a rectangular shape whose outer shape when viewed from the thickness direction is slightly smaller than the outer shape of the back recess 100 in plan view. Specifically, the display member 120 is sized to collectively cover each of the back insertion holes 101a within the back recess 100 and is formed smaller than the outer shape of the back recess 100 in plan view. However, the display member 120 only needs to be sized to cover at least any one of the back insertion holes 101a (the inner diameter of the back insertion hole 101a is smaller than the outer shape of the display member 120).

[0050] The thickness of the display member 120 is preferably less than the depth of the back recess 100 and is set to be less than half of the depth of the back recess 100. In the present embodiment, the thickness of the display member 120 is set to be less than 1 / 3 of the depth of the back recess 100. Therefore, all three display members 120 are accommodated in the back recess 100 so as not to protrude from the back recess 100.

[0051] The stacked state of each display member 120 will be described. Among the display members 120, the lowermost display member (first display member) 120A is attached onto the back bottom surface 100a in a state of collectively covering each insertion hole 101a. The lowermost display member 120A is exposed to the outside through the upper end opening of the back recess 100 in a state where only the lowermost display member 120A is attached onto the back bottom surface 100a. That is, in a state where only the lowermost display member 120A is attached onto the back bottom surface 100a, the identification information (first identification information) attached to the lowermost display member 120A is visible through the upper end opening of the back recess 100.

[0052] As shown in FIG. 4, the first upper layer display member (the first display member, the second display member) 120B is attached onto the surface of the lowermost layer display member 120A in a state of covering the surface of the lowermost layer display member 120A. That is, the first upper layer display member 120B is laminated on the lowermost layer display member 120A in a state of covering the identification information attached to the lowermost layer display member 120A. In a state where the lowermost layer display member 120A and the first upper layer display member 120B are laminated on the back bottom surface 100a, the identification information (the first identification information, the second identification information) attached to the first upper layer display member 120B is visible through the upper end opening of the back recess 100. Note that the first upper layer display member 120B may be laminated on the lowermost layer display member 120A in a state of being partially displaced with respect to the lowermost layer display member 120A as long as at least the identification information is covered.

[0053] As shown in FIG. 7, the second upper layer display member (the second display member) 120C is attached onto the surface of the first upper layer display member 120B in a state of covering the surface of the first upper layer display member 120B. That is, the second upper layer display member 120C is laminated on the lowermost layer display member 120A and the first upper layer display member 120B in a state of covering the identification information attached to the lowermost layer display member 120A and the first upper layer display member 120B. In a state where the display members 120A to 120C are laminated on the back bottom surface 100a, the identification information (the second identification information) attached to the second upper layer display member 120C is visible through the upper end opening of the back recess 100. Note that the second upper layer display member 120C may be laminated on the lowermost layer display member 120A and the first upper layer display member 120B in a state of being partially displaced with respect to the lowermost layer display member 120A and the first upper layer display member 120B as long as the respective identification information is covered. Further, in the illustrated example, the surface of the second upper layer display member 120C is positioned below the upper surface of the upper frame portion 32a (the upper end opening of the back recess 100).

[0054] Next, a method of using the chair 1 will be described. The chair 1 of this embodiment is installed in a state where a plurality of them are arranged side by side in a multi-purpose facility during use. At this time, by visually recognizing the identification information attached to the display member 120 accommodated in the back recess 100 or the seat-side recess 110, the seat or the like to be used can be confirmed.

[0055] As shown in FIGS. 4 and 7, in the case where a layout change occurs in a multi-purpose facility or the like, after rearranging the chairs 1, a new display member 120 (for example, the second upper-layer display member 120C shown in FIG. 7) is pasted on the uppermost-layer display member 120 (for example, the first upper-layer display member 120B shown in FIG. 4). For the new display member 120, for example, a labeler or the like may be used. Thereby, the identification information attached to the display member 120 located in the uppermost layer can be updated without peeling off the already pasted display member 120.

[0056] FIG. 8 is an explanatory diagram for explaining the removal operation of the display member 120 and is a cross-sectional view corresponding to FIG. 7. As shown in FIG. 8, when it is desired to newly stack the display members 120 in a state where a predetermined number (for example, three or more layers) of the display members 120 are stacked, or in other cases, during the pasting operation (information update operation) of the new display member 120, if there is a risk that the uppermost-layer display member 120 bulges out from the back recess 100, all the display members 120 are once removed from the back recess 100. For the removal operation of the display member 120, for example, a rod-shaped tool 150 (for example, a driver or the like) formed to have a diameter smaller than the minimum inner diameter of the back insertion hole 101a is used. Specifically, the rod-shaped tool 150 is inserted into the back recess 100 through the lower end opening of at least any one of the back insertion holes 101a. Then, the back surface of the lowermost-layer display member 120A is pushed up by the rod-shaped tool 150, so that the entire display member 120 is pushed up away from the back bottom surface 100a. As a result, only the back surface of the lowermost-layer display member 120A is peeled off from the back bottom surface 100a in a state where the display members 120 are joined together. Then, by pulling up each display member 120 from the back recess 100, each display member 120 can be removed collectively.

[0057] After removing each display member 120, by stacking a new display member 120 on the back bottom surface 100a again, it is possible to newly update the identification information each time the layout is changed.

[0058] As described above, the chair 1 of the present embodiment has bottom surfaces (pedestal surfaces) 100a and 110a, and a chair body 5 (backrest 2 and seat 3) in which recesses 100 and 110 that open upward (the first side in the first direction) are formed, and a plurality of display members 120 that can be stacked in the recesses 100 and 110. In a state where the plurality of display members 120 are stacked in the recesses 100 and 110, the upper display members (second display members) 120B and 120C are configured to cover the lower display members 120A and 120B so that at least the identification information of the lower display members 120A and 120B is not exposed to the outside through the openings of the recesses 100 and 110. According to this configuration, in a state where the plurality of display members 120 are stacked in the recesses 100 and 110, by covering the lower display members 120A and 120B with the upper display members 120B and 120C so that at least the identification information of the lower display members 120A and 120B is not exposed to the outside through the openings of the recesses 100 and 110, it is possible to display new identification information on the chair 1 without removing the lower display members 120A and 120B. That is, when changing the layout of the chair 1 or the like, by simply stacking new display members 120B and 120C on the lower display members 120A and 120B, a chair 1 with new identification information displayed can be provided. As a result, since it is not necessary to manage the chair 1 based on the originally attached identification information, the layout of the chair 1 can be easily changed. In this case, unlike the conventional method, it is not necessary to attach and detach the display plate each time the layout is changed, so the workability can be improved.

[0059] In the chair 1 of the present embodiment, the thickness of the display member 120 is configured to be half or less of the depth of the recesses 100 and 110. According to this configuration, even if the display members 120 are stacked, it is possible to suppress the upper display members 120B and 120C from bulging out of the recesses 100 and 110. As a result, when touching near the recesses 100 and 110 during sitting or when changing the layout, it is possible to prevent a hand or the like from touching the display member 120. This can suppress unexpected detachment of the display member 120 and improve usability and workability.

[0060] In the chair 1 of the present embodiment, in a state where the display members 120 are stacked within the recesses 100 and 110, the surfaces of the lower display members 120A and 120B (the surfaces facing the first side in the first direction) and the back surfaces of the upper display members 120B and 120C (the surfaces facing the second side in the first direction) are configured to be joined. According to this configuration, for example, compared to forming a structure in which a plurality of display members 120 can be stacked on the backrest 2 or the seat 3, the chair body 5 can be provided at a low cost.

[0061] In the chair 1 of the present embodiment, the display member 120 is provided with an adhesive layer on the back surface. According to this configuration, the lowermost display member 120A and the bottom surfaces 100a and 110a, as well as adjacent display members 120, can be joined via the adhesive layer. As a result, a seal-shaped display member 120 made of a base material such as paper or resin can be used, and the cost of the display member 120 can be reduced.

[0062] In the chair 1 of the present embodiment, the chair body 5 includes a display support portion (the upper frame portion 32a and the rear continuous portion 57) in which the recesses 100 and 110 are formed. The display support portion is configured to have insertion holes (through holes) 101a and 111a that penetrate the display support portion so as to open at the bottom surfaces 100a and 110a and are formed to have a smaller diameter than the display member 120. According to this configuration, by inserting a rod-shaped tool 150 or the like into the recesses 100 and 110 through the insertion holes 101a and 111a from below with respect to the display support portion, the display member 120 can be easily removed from the pedestal surface. Thereby, even when a plurality of display members 120 are stacked on the bottom surfaces 100a and 110a, the plurality of display members 120 can be easily removed together from the recesses 100 and 110. In particular, in the present embodiment, since a plurality of display members 120 are stacked, when the display member 120 is pushed up by the rod-shaped tool 150, it is possible to resist the pressing force by the rod-shaped tool 150. Thereby, it is possible to suppress the display member 120 from being punctured or the like, and it is easy to remove the plurality of display members 120 at once.

[0063] (Second Embodiment) FIG. 9 is a plan view of a recess according to the second embodiment. In the recess 200 shown in FIG. 9, fine uneven portions 200a1 are formed on the bottom surface 200a by embossing. The fine uneven portions 200a1 are formed in a region of the bottom surface 200a excluding the outer peripheral portion. That is, the bottom surface 200a includes a smooth portion 200a2 formed in a frame shape on the outer peripheral portion, and the fine uneven portions 200a1 surrounded by the smooth portion 200a2. In the illustrated example, the insertion hole 201 opens on the fine uneven portions 200a1.

[0064] According to the present embodiment, the contact area between the lowermost display member (first display member) 120A and the bottom surface 200a is reduced, and the lowermost display member 120A can be easily peeled off from the bottom surface 200a. Thereby, even when a plurality of display members 120 are stacked on the bottom surface 200a, the plurality of display members 120 can be easily removed together from the recess 200. Note that the formation range of the fine uneven portions 200a1 can be changed as appropriate.

[0065] (Other Modification Examples) As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other changes 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 embodiments, the case where all the display members 120 have the same configuration has been described, but the present invention is not limited to this configuration. The display members 120 of each layer may have different configurations from each other. In this case, the upper display member may have a configuration that covers at least the identification information in the lower display member. In the above-described embodiments, the configuration in which each display member is coupled via an adhesive layer has been described, but the present invention is not limited to this configuration. Each display member may have a configuration in which they are coupled by fitting such as unevenness or claws. Further, the display members are not limited to a configuration in which they are coupled by the coupling means provided in the display members, and may be accommodated in a stacked state in the recess by the coupling means (for example, claws) provided in the recess or the like.

[0066] In the above-described embodiments, the configuration in which the display member 120 is provided on the backrest 2 or the seat 3 has been described, but the present invention is not limited to this configuration. The display member 120 can be provided at any position of the chair body 5. In the above-described embodiments, the configuration in which the plurality of stacked display members 120 are pushed up and removed through the insertion holes 101a and 111a has been described, but the present invention is not limited to this configuration. A configuration in which the display member 120 is removed by inserting a tool or the like into the recesses 100 and 110 through the upper end openings of the recesses 100 and 110 may be employed. In this case, the insertion holes 101a and 111a are not an essential configuration. In the above-described embodiments, the case where the movable chair 1 is applied to the present invention has been described, but the present invention is not limited to this configuration. The chair 1 may be immovable.

[0067] In the above-described embodiments, the configuration in which the display member 120 is stacked in the recesses 100 and 110 has been described, but the present invention is not limited to this configuration. For example, as shown in FIGS. 10 and 11, a configuration in which only one display member 300 is provided in the recesses 100 and 110 may be employed. Specifically, the display member 300 includes a display plate 301 and a pin 302. The display plate 301 is arranged with the vertical direction as the thickness direction. Identification information is attached to the surface (upper surface) of the display plate 301. Pin 302 protrudes downward from the back surface (lower surface) of the display board 301. The pin 302 is inserted into each insertion hole 101a, 111a.

[0068] In the configuration shown in FIGS. 10 and 11, in order to update the identification information when changing the layout or the like, the pin 302 is pushed up using a rod-shaped tool 150 or the like. As a result, the display member 300 can be removed from the recesses 100, 110. Then, a new display member 300 is fitted into the recesses 100, 110 so that the pin 302 is inserted into each insertion hole 101a, 111a. In this case, if at least the insertion holes 101a, 111a are formed in the backrest 2 and the seat 3 that serve as the display support portion, the recesses 100, 110 as in the above-described embodiment are not an essential configuration.
