Description

[Technical Field]

[0001] The present disclosure relates to a chair. [Background technology]

[0002] Chairs have been proposed that are equipped with cup holders on which beverages and the like can be placed so that the occupant can use the chair more comfortably. For example, Patent Document 1 discloses a chair with an opening formed in the armrest that can be used as a cup holder. Patent Document 2 also discloses a cup holder that can be attached to the leg of a chair. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-142444 [Patent Document 2] Special Publication No. 2011-529380 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, there are cases where the legs or the like are configured to allow multiple chairs to be stacked one on top of the other (so-called nesting) so that they can be stored compactly when not in use. If nestable chairs are equipped with cup holders like the chairs disclosed in Patent Documents 1 and 2, the cup holders may interfere and prevent the chairs from getting close enough together when nested, which could result in an increase in the width in the front-to-back direction.

[0005] The purpose of the present disclosure is to propose a technology that enables good nesting in chairs equipped with cup holders. [Means for solving the problem]

[0006] One aspect of the present disclosure is a nestable chair comprising a seat body having a seating surface, a support body rotatably supporting the seat body, and a cup holder. The support body comprises a pair of left and right side portions located on the left and right sides of the chair, and a connecting portion connecting the pair of left and right side portions. The chairs are configured so that, when two of the chairs are nested together, insertion portions that are at least a part of the pair of left and right side portions of the chair located in the front or rear are inserted between the pair of left and right side portions of the chair located in the other position. The cup holder is arranged along the outer edge of the chair in the left-right direction, excluding the insertion portions.

[0007] With this configuration, the cup holder is positioned in a different location from the insertion portion that is inserted into adjacent chairs in front and behind when nesting, so the cup holder is less likely to affect nesting, allowing for smooth nesting.

[0008] In the chair described above, the cup holder may be arranged along a portion of the pair of left and right side portions excluding the insertion portion. Because the side portions are part of the support that supports the seat body, they are less likely to deform or shake when the chair is in use. Therefore, the cup holder arranged along the side portions is also prevented from shaking or displacing significantly when the chair is in use. As a result, the cup holder holds a cup or the like stably, making it easier for the seated person to use the cup holder.

[0009] In the chair described above, the cup holder may be positioned so that its upper end is located below the rotation axis of the seat body. In this configuration, the cup holder is located below the rotation axis of the seat body, which prevents the cup holder from interfering with the operation of rotating the seat body by hand or the like.

[0010] In the chair described above, the connecting portion may connect the pair of left and right side portions excluding the insertion portion, and the cup holder may be located on the left-right outer side of the connecting portion. In such a configuration, the position where the connecting portion is provided is likely to be stronger than other portions due to the connection between the side portions and the connecting portion, so that the cup holder located on that side can be prevented from shaking or displacing significantly.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [1. Embodiment] [1-1. Overall structure] 1A, 1B, and 2, chair 1 includes seat body 10, support body 20, backrest 30, memo stand 40, rod shelf 50, and cup holder 60. This chair 1 is a so-called nesting chair, which means that identical chairs 1 can be stacked in the front-to-back direction for storage.

[0013] In the following description, the configuration of each part may be explained using directions such as front-back, left-right, and up-down, but these directions are used merely for the convenience of explanation and do not limit the embodiments of the present disclosure in any way. For the purpose of easy understanding, the above-mentioned directions are based on the position of an occupant seated normally in chair 1.

[0014] The seat body 10 is formed by stretching a sheet-like mesh 13, which serves as a seating surface, over an area surrounded by a rectangular frame body 11 in a plan view (see FIG. 1A). This seat body 10 is provided with seat-side fixed pieces 15 on both the left and right sides of the rear end, at positions corresponding to a pair of left and right back-side connecting pieces 77 described below. By fastening the seat-side fixed pieces 15 and the back-side connecting pieces 77 to the seat-side fixed pieces 15 through a shaft 19, the seat body 10 is rotatably supported with respect to the support body 20. The center line of the shaft 19 is an example of the rotation axis of the present disclosure.

[0015] As shown in Figure 2, this seat body 10 has an inclined surface with an upward slope from its rear end to its front end at the seating position (seat body 10 shown by the solid line in Figure 2) described below, and the front end is a hanging piece that hangs down.

[0016] The frame body 11 of this seat body 10 has a pair of abutment members 17 on the backside of the left and right pieces extending forward and backward on the left and right sides, which abut against the connecting portion 80 described later to position the seat body 10 in a seated position.

[0017] The abutment member 17 protrudes from the rear surface of the frame body 11 and has a trapezoidal shape that narrows as it moves away from the frame body 11 in a side view (see FIG. 2). The amount of protrusion of the abutment member 17 from the frame body 11 is set so that the lower end of the mesh 13 does not come into contact with the connecting portion 80 even if the mesh 13 is deformed when a person sits on the seat body 10.

[0018] The support body 20 rotatably supports the seat body 10. The support body 20 includes a pair of left and right side members 70 located on the left and right sides of the chair 1, and a connecting member 80 that is a columnar member having a length in the left-right direction. Note that the left and right sides of the chair 1 refer to the left and right sides of the center of the seat body 10 in the left-right direction. Therefore, a portion of the side member 70 may be located closer to the center than the left and right ends of the seat body 10 in the left-right direction.

[0019] Each of the pair of left and right side portions 70 has a front leg 71, a rear leg 73, a support side connecting piece 75, and a back side connecting piece 77. The front legs 71 are columnar members that extend forward and downward from positions closer to the center of the left and right ends of the connecting part 80. The rear legs 73 are columnar members that extend rear and downward from the left and right ends of the connecting part 80, which are positions outside the positions where the front legs 71 are provided on the connecting part 80. Casters 79 are provided at the lower end of each leg.

[0020] The support-side connecting pieces 75 are columnar members extending rearward and upward from the left and right ends of the connecting portion 80. The back-side connecting piece 77 is a columnar member whose lower end is connected to the upper end of the support-side connecting piece 75 to form a single rod.

[0021] As described above, the back connecting pieces 77 are positioned so that they sandwich the rear end of the seat body 10 from the left and right. The back connecting pieces 77 secure the seat body 10 so that it can rotate about the shaft 19 extending in the left-right direction. As a result, as shown in Figure 2, the seat body 10 can rotate between a seated position (seat body 10 shown by the solid line in Figure 2) in which the seat body 10 is reclined so that the mesh 13, which forms the seating surface, is flush with the ground, and an upright position (seat body 10A shown by the two-dot chain line in Figure 2) in which the seat body 10 is flipped up so that the seating surface intersects with the ground.

[0022] The connecting portion 80 has a width in the front-rear direction greater than its thickness in the vertical direction, and has a flat upper surface. When the seat body 10 is in the seating position, the abutment member 17 abuts against the upper surface of the connecting portion 80.

[0023] The backrest 30 is a plate-like member with an upper portion tilted slightly backward and an arc-shaped portion that convexly faces backward in plan view, so that it fits the back of a seated user. The lower ends of the backrest 30 on both the left and right sides are integrally formed with back-side connecting pieces 77, and are thereby supported by the support body 20 via the support-side connecting pieces 75.

[0024] Memo stand 40 is attached to chair 1 via arm 41 extending from connecting part 80. A rotation support part 43 is provided at the tip of arm 41, and this rotation support part 43 allows memo stand 40 to move between a use position and a storage position.

[0025] 1A, 1B, and 2, the notepad 40 is in a horizontal position with a slight upward tilt at the front, allowing you to write notes or place a notebook-type personal computer on it. The storage position is along the right side of the chair 1, as shown by the dashed line in FIG. 1B.

[0026] A part of the rotation support part 43 rotates about a rotation axis extending substantially from front to back from the use position described above, and the memo stand 40 moves to an upright position (the upper part of the memo stand 40 shown by the two-dot chain line in FIG. 2). In this state, the rotation support part 43 rotates about a rotation axis extending substantially from left to right, and the memo stand 40 moves to a storage position (the lower part of the memo stand 40 shown by the two-dot chain line in FIG. 2).

[0027] The rod shelf 50 is a shelf located below the support 20 and is formed by bending a metal rod. The rod shelf 50 is assembled in a generally flat shape and is inclined so that the front faces slightly downward. The rod shelf 50 is attached to the connecting part 80 via a connecting part 51 that extends vertically.

[0028] Cup holder 60 is a cylindrical member with a bottom, and is configured to be able to hold, for example, a container such as a cup or a plastic bottle. Through holes are formed in the bottom and part of the side. In this embodiment, cup holder 60 is positioned outside, to the left of connecting part 80. Cup holder 60 is also positioned so that its upper end is located below the rotation axis of seat body 10 (i.e., the center line of shaft body 19).

[0029] As shown in Figure 3, cup holder 60 is connected to support body 20 via cup holder mounting bracket 61. Cup holder mounting bracket 61 has a holder holding portion 63 that fixes cup holder 60 with a screw, and a frame connecting portion 65 that is attached to connecting portion 80 with a screw. Holder holding portion 63 is fixed to the side surface (i.e., the cylindrical portion) of cup holder 60. Frame connecting portion 65 is fixed to the underside of connecting portion 80. The upper end surface of cup holder 60 is at approximately the same height as the upper end surface of connecting portion 80.

[0030] [1-2. Nesting Operation] The pair of left and right side portions 70 are formed so that the distance between the pair of left and right rear legs 73 is wider than the distance between the pair of left and right front legs 71. This allows chairs 1 of the same shape to be stacked in the front-to-rear direction, as shown in Fig. 4A.

[0031] FIG. 4B shows a schematic right side view of the nested chairs 1, with the memo stand 40 and rod shelf 50 omitted. When two chairs 1 are nested, the insertion portions 91 of the pair of left and right side portions 70 of the rear chair 1 are inserted between the pair of left and right side portions 70 (rear legs 73) of the front chair 1. Note that the insertion portions 91 here refer to at least a portion of the pair of left and right side portions of the chair 1 that is positioned either in the front or rear when nested. In this embodiment, as shown in FIG. 4B, the insertion portions 91 refer to the portions of the front legs 71 that are forward of the portions that overlap with the rear legs 73 of the front chair 1 when nested in a side view.

[0032] When nesting, the memo stand 40 is moved to the storage position and the seat body 10 is moved to the upright position. Because the memo stand 40 and rod shelf 50 are slightly inclined in the front-to-rear direction, they do not interfere with the memo stands 40 and rod shelves 50 of the chairs 1 in front and behind, allowing nesting. Furthermore, the cup holders 60 do not interfere with the cup holders 60 of the chairs 1 in front and behind when nested. In this embodiment, the backrest 30 of the front chair 1 and the abutment member 17 of the rear chair 1 can approach each other during nesting to a position where they come into contact. However, the chairs 1 may be configured to be able to approach each other until other parts of the chairs 1 interfere with each other during nesting. Although FIGS. 4A and 4B show two chairs 1 nested together, three or more chairs can be nested together in the same manner.

[0033] [1-3. Cup holder installation variations] Cup holder 60 is disposed on the outside of connecting portion 80 as described above, but if cup holder 60 is positioned at a position other than insertion portion 91 shown in FIG. 4B, nesting is less likely to be restricted.

[0034] For example, cup holder 60 may be provided at a position other than insertion portion 91, along any part of the outer edge portion in the left-right direction of chair 1 (outer edge portion 93 shown in FIG. 4B ). Specifically, outer edge portion 93 includes the portion of front leg 71 rearward of insertion portion 91, rear leg 73, the sides of connecting portion 80, support-side connecting piece 75, back-side connecting piece 77, and the left and right ends of backrest 30. In this embodiment, outer edge portion 93 is a portion that can be seen from the side.

[0035] Furthermore, for example, cup holder 60 may be provided along any part of side portion 70 other than insertion portion 91 (specific side portion 95 shown in FIG. 4B ). Specifically, specific side portion 95 includes the part of front leg 71 rearward of insertion portion 91, rear leg 73, the side of connecting portion 80, support-side connecting piece 75, and back-side connecting piece 77. Cup holder 60 may be disposed so as to overlap outer edge portion 93 or specific side portion 95 described above in a side view.

[0036] Cup holder 60 may also be attached via an arm. In this case, it is preferable that the arm itself is positioned so as not to interfere with nesting. Note that the position where cup holder 60 is positioned does not refer to the position where an arm or metal fitting is attached on the chair body, but the position where cup holder 60 itself is positioned. In other words, for example, "cup holder 60 is positioned along the left and right outer edges of a pair of side portions 70" means that cup holder 60 is positioned on the left and right outer sides of side portions 70, regardless of how cup holder 60 is connected to side portions 70.

[0037] [1-4.Effects] According to the embodiment described above in detail, the following effects can be obtained. (1a) Chair 1 is configured so that when two chairs 1 are nested, insertion portion 91, which extends from the front end to partway through front leg 71 of the rear chair 1, is inserted between rear legs 73 of the front chair 1. Cup holder 60 is provided along outer edge 93. More specifically, cup holder 60 is provided in the portion of side portion 70 located on the left side excluding insertion portion 91, along a position that is outwardly to the left of connecting portion 80. Therefore, because cup holder 60 does not hinder nesting, chairs 1 can be nested with a sufficiently small gap between them.

[0038] (1b) In chair 1, cup holder 60 is provided along a portion of side portion 70 excluding insertion portion 91 (specific side portion 95). Side portion 70 has high strength to support seat body 10, which prevents cup holder 60 from shaking or displacing significantly when chair 1 is in use. This stabilizes cup holder 60, making it easier for the seated person to use cup holder 60. Furthermore, cup holder 60 is provided at a position outside connecting portion 80. The position at which connecting portion 80 is provided is stronger than other portions due to the connection between side portion 70 and connecting portion 80, further stabilizing cup holder 60.

[0039] (1c) In chair 1, the upper end of cup holder 60 is located at a position lower than the center line of shaft 19 (the rotation axis of seat 10), which prevents cup holder 60 from interfering with the operation of rotating the seat by hand or the like.

[0040] [2. Other embodiments] Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above embodiments and can take various forms as long as they fall within the technical scope of the present disclosure.

[0041] (2a) The specific configuration of the chair 1 can be various forms as long as nesting is possible. For example, the insertion portion may be the rear legs. In other words, the pair of rear legs of the chair 1 placed in front may be configured to be inserted between the pair of front legs of the chair 1 placed behind.

[0042] Furthermore, there are no particular limitations on the specific shapes of the front legs 71, rear legs 73, support-side connecting piece 75, and back-side connecting piece 77. For example, in the above embodiment, the support-side connecting piece 75 and back-side connecting piece 77 are combined, but they may be originally one member, in which case the main portion of the backrest 30 and the back-side connecting piece 77 may be different members.

[0043] Furthermore, the specific shape of the support body 20 is not particularly limited as long as it has parts that perform the same functions as the front legs 71, rear legs 73, support side connecting pieces 75, connecting parts 80, and the like. Furthermore, the memo stand 40, rod shelf 50, and casters do not have to be provided. The connecting portion 80 does not have to be a member that supports the seat body 10 in the seated position. The cup holder 60 may be provided on the right side.

[0044] (2b) In the above embodiment, a cylindrical member having a bottom was exemplified. However, the specific shape of the cup holder can be various as long as it is configured to hold a cup. For example, the cup holder may be ring-shaped or cage-shaped and made of a linear member formed of metal, resin, or the like. Furthermore, for example, the cup holder may be a member having a through hole and configured to hold a cup whose diameter decreases toward the bottom by the edge of the through hole.

[0045] (2c) Multiple functions of one component in the above embodiments may be realized by multiple components, or one function of one component may be realized by multiple components. Also, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Also, part of the configuration of the above embodiments may be omitted. Also, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments. [Explanation of symbols]
