Description

[Technical Field]

[0001] The present invention is Seat area and table board Panel Prepared Chair with panel It is about units. [Background technology]

[0002] Traditionally, office furniture generally consisted of a desk and chair set, with single or multiple desks arranged side by side, with many people working in a row. It was also common to arrange rows of desks back to back. In these traditional working styles, a fixed address system was common, with specific people using specific seats.

[0003] However, in recent years, office working styles have been undergoing major changes, such as the free address system (non-territorial system) where employees can work wherever they like without being assigned a specific seat, the style where employees work in separate desks for one person, and the group working style where multiple people share a common seat.

[0004] One of the reasons behind these changes in working styles is the miniaturization of information devices such as laptops and tablets, which are used as work tools. In other words, because these laptops and tablets are easily portable, there is no longer a need to work at a specific desk, and as a result, the free address system has become increasingly popular.

[0005] Another factor behind this trend is the development of environments that bring out the creative abilities of workers. In other words, to enhance a worker's creative abilities and increase their intellectual productivity, they need an environment where they can concentrate on their thoughts, relax, or easily receive intellectual stimulation through discussions with colleagues. This has led to the trend toward separate seating and grouping. Therefore, it is preferable to be able to choose a seat according to purpose.

[0006] The balance between the closedness and openness of the environment surrounding a worker is important in relation to a worker's ability to concentrate and relax. For example, in a completely private room, external stimuli are diluted too much, leading to a lack of tension and often a drop in productivity. On the other hand, in an overly open environment, such as when working alone at tables scattered across a large floor, the worker is distracted by other people's movements and conversations and is concerned about their gazes, making it difficult to concentrate on thoughts and also difficult to adopt a relaxed posture (such as stretching or meditating) out of consideration for others.

[0007] Furthermore, intellectual productivity is closely related to the ease of use of devices such as laptops. In other words, if devices such as laptops are easy to use like your hands and feet, you can work more efficiently, but if the device is difficult to use, not only will you be distracted by the operation and neglect your essential thoughts, but it may also increase the strain on your body (for example, your arms), accelerating fatigue.

[0008] So, when we look at actual furniture (fixtures), we can find examples of furniture with a high degree of openness, such as those disclosed in Patent Documents 1 and 2. Patent Documents 1 and 2 show sofa-type chairs with foldable table tops attached, and when the table top is placed in a horizontal position, a laptop computer can be used.

[0009] On the other hand, an example of office furniture with a high degree of closedness is Patent Document 3. This Patent Document 3 divides a space with a partition that is shaped like a gudgeon when viewed from above, forming four work spaces, and each work space has a tabletop attached with its back facing the partition wall. Therefore, people work facing the partition wall. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-125616 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-58564 [Patent Document 3] CD-ROM of Jikkai Hei 05-29368 Summary of the Invention [Problem to be solved by the invention]

[0011] As mentioned above, in order to increase a worker's intellectual productivity, it is important to have a balance between the closed and open aspects of the work environment, and to ensure that the equipment (especially laptops) is easy to operate. However, although Patent Documents 1 and 2 are somewhat heavier than the pipe chair with a memo stand, they are too open, and it is difficult to say that they will contribute to improving intellectual productivity even when used for office work.

[0012] In addition, the table top is attached to the side of the chair and is entirely located above the seat, so when sitting down or leaving the chair, the table top must be flipped up and stored on the side of the chair, which is uncomfortable and not very user-friendly.

[0013] On the other hand, Patent Document 3 provides a kind of private room, which is too closed off and may result in insufficient improvement in intellectual productivity. Furthermore, Patent Document 3 also lacks convenience, as the tabletop, which is the same size as a regular desk, is surrounded on three sides by partition walls.

[0014] The present invention has been made to improve this situation, and is an innovative and user-friendly system with an unprecedented configuration. Panel-attached chair unit It should be noted that many novel aspects are presented in this application, and these novel and improved aspects are Panel-attached chair unit It may also be an objective to provide [Means for solving the problem]

[0015] The present invention This relates to a chair unit with a panel, As per claim 1, " A seat with a backrest, Panels surrounding the seat from the left and right sides and rear; a table plate used by a seated person sitting on the seat portion, The tabletop is supported by a height adjustment mechanism so that it can be raised and lowered. That composition is.

[0016] The present invention can be developed in various ways. Examples are given in each claim. The invention of claim 2 is as follows in claim 1: "The height adjustment mechanism is an expansion and contraction type in which a cylindrical outer member and an inner member are fitted together so as to be able to move relative to each other." It is structured as follows. It is also possible to employ a configuration in which the forward / backward position and the posture of the cable board can be adjusted separately.

[0017] Claim 1 or As a specific example of claim 2, claim 3 states: "The seat is supported from below by long stays in the left-right direction." The structure is as follows.

[0018] Claim 4 Now, the claim Any of 1 to 3 In "The panels include left and right side panels and a rear back panel, which are continuous in the circumferential direction." The structure is as follows.

[0019] Claim 1~ 3 As an example of a development of any of the claims, 5 So, "The table plate is supported by the height adjustment mechanism in a state where its position can be adjusted forward and backward." The structure is as follows.

[0020] The invention of claim 6 Please also Request 1~ 3 one of This is an example of the expansion of "The table top can be changed between a horizontal position and a backward tilted position." The structure is as follows. The invention of claim 7 is also a development example of any of claims 1 to 3, " The panel has left and right side panels and a back panel, each consisting of two panels, a lower panel and an upper panel, The lower panel is higher than the seat surface and lower than the upper end of the backrest, The upper panel is higher than the top of the backrest. The structure is as follows.

[0021] Claim 8 is a development example of claim 7, "The upper panel is membrane-like." The structure is as follows.

[0022]

[0023] [Effects of the Invention]

[0024] In the present invention, the table top is, It can be used in the same condition as a regular desk top. Therefore, it is suitable for office use. Height (also front and rear positions in claim 5) The table top can be adjusted to suit the user's preferences and working conditions. Height (and front-to-back position) This can greatly contribute to improving intellectual productivity.

[0025] In addition, since the table top is located in front of the seat, it is easy to leave and return to your seat with devices such as a laptop computer or documents on the table top, making it user-friendly and suitable for office use. do.

[0026] The table top is designed so that you can <Height (and Anteroposterior position ) Although the structure may be modified, 6 Like To the side By adopting a configuration that allows the viewing posture to change, for example, when the table top is pulled forward while leaning backward, it becomes easier to operate the keys on a laptop computer placed on the table top and also makes it easier to see the monitor.

[0027] In other words, when the user is standing upright, they are looking down at the tabletop, so if the tabletop is placed in a roughly horizontal position, the laptop of operation or Writing Action However, if you lean your body back, you will be looking at the tabletop at an angle, so it is easier to operate a laptop or write on it if you keep the tabletop tilted back from the horizontal. And, as in the embodiment, the rotating supportWhen this is adopted, the tabletop can be automatically adjusted to a comfortable position according to the user's posture, in conjunction with the adjustment of the front and back positions. R .

[0028]

[0029] Now, when working with a laptop placed on a tabletop, the laptop's LCD monitor is best viewed from a direction perpendicular to the screen, so when a person stands with their upper body upright, their head is tilted slightly forward and the laptop monitor is tilted back more than vertical. However, when a person leans their body back, their head moves back and downward, so the angle their line of sight makes with the horizontal (elevation angle) becomes smaller. Therefore, simply pulling the tabletop closer to the person results in a situation where they are looking up at the monitor from below, making it difficult to see the text on the monitor.

[0030] In contrast, An embodiment using a rotating support column When a person leans back and pulls the tabletop toward their body, the tabletop tilts forward and the laptop monitor also changes position to approach vertical, automatically maintaining the relationship between the monitor and their line of sight in an appropriate state so that the person's line of sight is kept approximately perpendicular to the screen.

[0031]

[0032] Further, embodiments Like, Uses a rotating support Pillar pivot point of When positioned behind the front edge of the tabletop, the tabletop tilts backward without significantly lowering its height, so even if the tabletop's front-to-back position changes, people can operate the laptop with their hands naturally extended without significantly changing the height of their wrists, resulting in excellent operability of the laptop.

[0033] Te The front and rear position and angle of the cable board can be adjusted separately. andThe condition of the tabletop can be finely adjusted according to the user's preferences.

[0034] Claim 4 When the configuration of Constructing a panel that is U-shaped when viewed from above The left and right side panels and the back panel are connected in a continuous line, which gives the chair a more solid feel and further enhances its territory definition function, contributing to the creation of an environment where the user can concentrate on their work. In particular, if the height of the side panels and back panel is set so that the seated person's head is hidden, the sense of closure is further enhanced, which is ideal for realizing an environment where the user can concentrate on their work.

[0035] When the side panels and back panel are at a height that just covers the head of a seated user, for example, the side panels and back panel define a work space surrounding the user. However, the difference with Patent Document 3 is that in Patent Document 3 the user has their back to the opening of the furniture (partition device), whereas in the present invention the table top is positioned at the opening of the work space, and the user sits with their back to the back panel and facing the opening of the work space.

[0036] In this way, a space is formed that is enclosed by the side and back panels, and the user faces the opening, which harmonizes the closed and open feel and allows the user to concentrate on their work with a moderate sense of tension, which can be said to improve intellectual productivity.

[0037]

[0038] As mentioned above, it is possible to increase the height of the side panels and back panel to make the work space more closed off, but in this case, the side panels and back panels function as strength members and are usually of a certain thickness but not translucent, so simply increasing the height of the side panels and back panels may result in a feeling of increased oppression.

[0039] In contrast, if the configuration of claim 7 is adopted, The side panel part of the lower panel By making it possible to use it as an elbow pad, it increases the convenience of the user, Top Panel This makes it possible to eliminate the feeling of pressure and ensure a moderate degree of closedness. Top Panel It is particularly preferable to use a translucent, non-transparent resin plate, such as a frosted glass-like resin plate, since this eliminates the feeling of oppression while ensuring a moderate degree of closure.

[0040] Embodiment By providing a front panel like this, the concealing function helps to increase concentration on work. This is particularly desirable for women. Another advantage is that bags and other belongings can be placed behind the front panel while remaining hidden. Furthermore, by abutting the front panel against the floor, the front panel and the front panel reinforce each other, increasing stability. This means that the chair can stand on its own even without a back panel located behind the seat, thereby increasing design freedom.

[0041] Embodiment By providing a base plate as shown, the chair can stand upright and become more stable. It also makes it easier to place bags. Adding foot support to the base plate has the advantage of improving comfort.

[0042] When a cavity is provided in the side panel as in the embodiment, The side panels can be used as storage areas for items. hand It is very useful. It is also possible to install a power outlet or USB port in the hollow part and use it to charge a smartphone. The hollow part faces the seated person, so it is essentially blocked by the user, making it useful as a place to store valuables.

[0045] Next, an embodiment of the present invention and reference examples The following will be explained based on the drawings. In this application, the terms "front, back, left, right" are used to specify directions, but these directions are based on the direction of a person normally sitting on the chair. A front view is a view from the direction opposite the seated person. The forward and backward movements of the table top refer to the movement of the table top towards the seated person. but Moving backwards means moving away from the occupant, while moving forwards means moving forward.

[0046] (1) Overview of the First Embodiment First, an outline of the first embodiment will be explained based on Fig. 1 and Fig. 2(A). The furniture of the first embodiment comprises a chair part 3 consisting of a seat 1 and a backrest 2, and left and right side panels located on the left and right outer sides of the chair. bottom Side panels 4 and 5, a back panel 6 located behind the seat part 3, and a right At the bottom It has a front panel 7 located in front of the side panels 5, and a table top 9 is attached to the front panel 7 via support posts 8 so that it can rotate back and forth. The table top 9 is large enough to stably place a laptop computer (not shown), and has horizontally elongated stoppers 10 at its rear end to prevent the laptop computer or other device from slipping off.

[0047] Left and right bottom Side panels 4, 5 and bottom The back panel 6 is integrally connected. bottom Side panels 4, 5 and bottom Together with the back panel 6, a forward-facing, open, U-shaped enclosure is formed. bottom Side Panels 4,5 An upper panel 11 is erected on the lower back panel 6, and the side panels and back panel are configured in two stages. The lower side panels 4, 5 are at a height that allows a seated person to rest their elbows on, and are therefore higher than the seat surface and lower than the top end of the backrest 2. The lower side panels 4, 5 are The width must be such that a seated person can rest their elbows stably (for example, around 20 cm). The upper panel 11 is A shroud made of thin plate material such as a resin plate and is erected on the upper surface of the lower panel.

[0048] The top panel 11 is Therefore, even though it is a thin plate, it is highly stable. Top Panel 11 can be made of a translucent but opaque resin plate, such as a milky white acrylic resin plate. Of course, a plate material that does not translucently transmit light can also be used. A screen-shaped (film-shaped) plate can also be used.

[0049] Top Panel 11 is Higher than backrest 2 The seat is set at a height that covers the head of the seated person, but it can also be set at shoulder height or higher than the head of the seated person. death It is also possible to The top panel 11 is for example, bottomThe height of the side panels 4 and 5 can be lower than the height of the back panel 6, bottom At the locations of the side panels 4 and 5, it is also possible to incline the upper surface so that the height decreases toward the front.

[0050] Also, Top Panel 11 is bottom Side panels 4, 5 and bottom Back Panel 6 In the bottom panel The seats are positioned outward. bottom The elbows can be stably rested on the upper surfaces of the side panels 4 and 5. bottom The side panels 4 and 5 can be used as elbow rests. bottom On the top surfaces of the side panels 4 and 5, items such as writing implements, booklets, and smartphones can be placed. bottom The side panels 4 and 5 can also be used as a platform for placing items.

[0051] In this embodiment, the front panel 7 is formed in a hollow rectangular box shape. bottom The width is set to be approximately the same as that of the side panels 4 and 5. Top Panel The front partition plate 12 is set upright and is set outward so that it is aligned with one side of the front panel 7 in a plan view. Therefore, the upper surface of the front panel 7 can be used as a table for placing items and as a work surface for operating a mouse, etc. Top Panel It is preferable that the material be the same as that of 11. It is also preferable that the two are connected by a joint.

[0052] The front panel 7 has a rectangular shape in plan view, but other shapes in plan view, such as a trapezoidal shape that widens or narrows in front, can also be used. Also, as will be described in other embodiments, it does not have to have a hollow structure, and it may even have a top panel attached to a support. Furthermore, from the viewpoint of shielding function, it is preferable that it be in the form of a panel with a surface area, but from the viewpoint of the function of attaching the table board 9, it may be a structure in which a top board or frame material is attached to the upper end of the support pillar, for example. Therefore, rather than using the term "front panel," it may be more appropriate to call it a front member that has at least one of the following functions: shielding function, table board attachment function, and workbench function.

[0053] As shown in Figure 2(A), Nopa Nell 4,5 ,11 The seat part 3 and the left seat part 4 are inclined at a slight angle to the center line of the longitudinal direction in a plan view so that they widen toward the front. Right Pa Nell 4,5 ,11 and back panel 6 ,11 The furniture body, which is composed of the above, has a trapezoidal shape in a plan view. On the other hand, the front panel 7 is arranged parallel to the longitudinal center line. bottom right The side panel 5 is disposed in a bent position in a plan view.

[0054] The support pillar 8 is L-shaped with a rearward-facing portion 8b at the lower end of a base portion 8a extending vertically, and the rear end of the rearward-facing portion 8b is rotatably connected to the inner surface of the front panel 7. When the base portion 8a of the support pillar 8 is in a vertical position, the table top 9 is in a substantially horizontal position, and in the horizontal position, the rearward-facing portion 8b rests stably on the floor. The advantages of pivoting around the rear end of the rearward-facing portion 8b will be described later.

[0055] (2) Example of layout with multiple furniture Front Panel 7 bottom It is separate from the side panels 4 and 5, and can be mounted on either the left or right side. bottom It can also be connected to the side panels 4 and 5. The front panel 7 has left and right sides, but the table top 9 can be attached to either side. By appropriately combining the connecting position of the front panel 7 and the position of the table top 9, various layouts can be realized. Examples are shown in Figures 2(B) to 3.

[0056] In the layout example shown in Figure 2(B)(C), many pieces of furniture are (Chair unit with panel) The furniture pieces are connected to the left and right with their opening directions alternating, so that a zigzag shape is formed in a plan view by the numerous pieces of furniture. Therefore, the furniture pieces in the middle, excluding the furniture pieces at both ends, leave a passage-like space in front of the user. In other words, the furniture pieces in the middle are recessed. This results in a high degree of closedness. In this layout example, only one front panel 7 is placed between the furniture pieces placed in front and behind.

[0057] In the layout examples of Figures 2(B) and (C), right-handed tabletops 9 positioned to the right of the seated person and left-handed tabletops 9 positioned to the left of the seated person are arranged alternately on the left and right. Therefore, the distance between adjacent tabletops 9 on the left and right is constant.

[0058] On adjacent furniture, bottom The side panels 4, 5 and the front panel 7 are aligned in series and on the same plane. Top Panel 11 and the front partition plate 12 are provided, Top Panel A gap is formed between the front end of the front partition plate 11 and the front end of the front partition plate 12. This gap can be actively used for communication with the person sitting next to you, or it can be closed.

[0059] If you want to close the gap, bottom A front plate is provided at the front edge of the side panels 4 and 5. Top Panel The front end of the front panel 7 may be configured to be L-shaped in plan view, or a front plate may be provided at the front end of the front panel 7, and the front partition plate 12 may be configured to be L-shaped in plan view. Top Panel In either case, the front panel or the shielding panel can be attached to the material and height. Top Panel 11 and the front partition plate 12 are preferably aligned in the same manner.

[0060] Shift adjacent furniture from front to back to the left or right, and Top PanelIt is also possible to arrange the front end of the front partition panel 11 of the other piece of furniture so that it butts against the front end of the front partition panel 12 of the other piece of furniture, in which case no gap will be created.

[0061] As mentioned above, there is a passage-like space in front of the furniture in the middle except for the two ends of the furniture group, but the left and right side panels 4,5 ,11 Because the space is configured in a V-shape, the entrance to the corridor-like space is wide, making it easier for people to enter and exit. In addition, the space has a certain degree of openness, which helps to reduce the feeling of oppression.

[0062] In Figures 3(A) and (B), two pieces of furniture are arranged facing each other from front to back. Therefore, the two pieces of furniture form an approximately C-shaped space. When the table tops 9 of the front and rear pieces of furniture are not rotated forward, they are abutting or close to each other back to back. In this embodiment, the two pieces of furniture form a space with one entrance and exit. Therefore, the overall space has a high degree of closedness. Therefore, it is suitable for situations where high shielding from the outside is required, such as business negotiations or confidential meetings.

[0063] In the layout examples of Figures 3(C) and (D), two pieces of furniture, each with a front panel 7, are arranged so that their openings are offset to the left and right and open in opposite directions. Because there are two front panels 7 at the boundary between adjacent pieces of furniture, the distance between the front and rear pieces of furniture is longer than in the case of Figures 2(B) and (C).

[0064] In the layouts (C) and (D), the table top 9 is positioned to the left of the user for left-handed use, while in the layout examples shown in Figures 3(E) and (F), the table top 9 is positioned to the right of the user for right-handed use. In both the layout examples (C) and (D) and the layout examples (E) and (F), these can be used as one unit and multiple units can be connected to the left and right, in which case the layout will be similar to the layouts in Figures 2(B) and (C).

[0065] Front panel 7 is the left bottomThe table can be used left-handed, with the table top 9 attached to the side panel 4, or right-handed. bottom There is a right-hand use version in which a table board 9 is attached to the side panel 5, but these left-hand and right-hand use versions may be prepared as dedicated items in advance, or may be accommodated by switching the support posts 8 to the right and left sides of one type of front panel 7.

[0066] In the embodiments (C) to (F), a table top 9 is attached to each of the two front panels 7 arranged in a row, but it is also possible to share one front panel 7 between the front and rear furniture pieces and attach table tops 9 to both sides of the panel. In this case, too, a dedicated product with table tops 9 attached to both sides may be prepared, or the front panel 7 may be shared and table tops 9 may be attached to both sides of the single front panel 7.

[0067] Although not shown in the diagram, it is also possible to place two pieces of furniture back to back. It is also possible to place them side by side with their openings facing in the same direction. In each layout example, adjacent pieces of furniture may be connected to each other, or simply placed side by side.

[0068] Forming the chair portion 3 into a trapezoidal shape in plan view as in this embodiment has the advantage of making it easier to sit down and get up, whether the furniture is used alone or in a row. In particular, when the chairs are arranged facing each other as in Figure 3(A) or in a zigzag pattern as in Figures 2(B) and (C), it is preferable because it allows for a wide space for entering and exiting.

[0069] For example, a typical single-person chair has a width from side to side that is roughly the same as the maximum width of the user. Therefore, if a table top is provided along with left and right side panels, a person cannot sit or leave the chair unless the table top is flipped up.

[0070] In contrast, in the present embodiment, the seat is about 1.5 times wider than a normal chair, so by shifting the table top to the right or left, it is possible to create space beside the table top 9 for people to enter and exit. Also, in the initial state when the support pillar 8 is not tilted backward, there is a distance between the table top 9 and the seat 1 in the front and back directions so that a person can insert their feet. Therefore, people can sit down and get up without the need to make the table top 9 a flip-up type. Therefore, it is possible to sit down and stand up with items such as a laptop computer left on the table top 9. This makes it extremely easy to use.

[0071] Moreover, as in this embodiment, (seat) If 3 is formed into a trapezoid in plan view, the space above the seat 1 will widen forward, making it easier for people to slide their body in when sitting down and to move away when leaving. This makes it even easier to sit down and leave. Also, from a visual (psychological) perspective, it gives a strong impression that the chair is easy to sit down and leave and is easy to use. In addition, side panels 4 and 5 ,11 It is also possible to have it protrude in front of the seat 1, but in this case, the ease of sitting down and getting out of the seat becomes even more pronounced when it is formed into a trapezoid in plan view.

[0072] (3) Specific examples of structures Next, the structure of each part will be described mainly with reference to FIG. bottom Panel 4~ 6 and front panel 7 It has a hollow structure with an outer peripheral plate, an inner peripheral plate, and a top plate. A bottom plate may or may not be present. The outer peripheral plate and the top plate may be made of wood or metal such as steel. Resin molded products may also be used. In any case, it is preferable to cover at least the surface that comes into contact with the human body with a covering material such as cloth. bottom The upper surfaces of the side panels 4 and 5 may be provided with cushioning material.

[0073] The seat 1 has a structure in which cushioning material 16 is stretched over a seat board 15, and the cushioning material 16 is covered with a surface material. The seat board 15 can be made of a wooden board, a metal board, a resin board, or the like, as required. The seat board 15 has left and right bottomIt is supported (fixed) by stays 17 that span the side panels 4 and 5. The backrest 2 also has a structure in which cushioning material 19 is stretched over a back panel 18, which is fixed to the back panel 6. The cushioning material 19 of the backrest 2 is also covered with a covering material. The width of the seat portion 3 is set slightly wider than that of a normal chair, allowing for a relaxed sitting position.

[0074] The support 8 is an example of a height adjustment mechanism. A bracket 20 is fixed to the upper end, and a table plate 9 is fixed to the bracket 20 with screws or the like. A horizontally elongated rotating shaft 21 is fixed to the rearward-facing portion 8b of the support column 8, and the rotating shaft 21 enters the interior of the front panel 7 via a collar 22. Meanwhile, a bearing tube 23 into which the rotating shaft 21 is fitted is disposed inside the front panel 7, and the bearing tube 23 is fixed to the inner and outer plates of the front panel 7 (it may also be fixed to the bottom plate).

[0075] Slits 24 that open upward are formed in the left and right midpoints of the bearing sleeve 23, and a movable friction plate 25 is fixed to the rotating shaft 21 at the location of these slits 24. Fixed friction plates 26 on the left and right are fixed to the bearing sleeve 23 so as to sandwich the movable friction plate 25, and friction material 27 with a large friction coefficient is attached to the fixed friction plates 26 and the movable friction plates 25.

[0076] When a certain amount of pulling or pushing force is applied to the table top 9 from the front or rear, the table top 9 can be rotated back and forth against the friction between the friction materials 27. When the hands are released from the table top 9, the table top 9 is maintained in a state where it cannot be rotated even by operating the laptop computer or writing on it.

[0077] Various means can be used to maintain the front-to-rear position of the table plate 9 (the attitude of the support column 8), such as placing a friction plate or a coil spring between the collar 22 and the front panel 7. In this embodiment, the front-to-rear position of the table plate 9 can be adjusted continuously, but a stepped adjustment method can also be used. It is also possible to employ a locking means that can be switched between a locked state and an unlocked state by operating a lever, and to provide the lever on the table plate 9 or the front panel 7.

[0078] Top Panel As shown in FIG. 4(C), the mounting means for the front partition plate 11 and the front partition plate 12 is as follows. Top Panel A downward-facing foot 30 is provided on a receiver 29 that clamps and holds the lower ends of the front panel 11 and the front partition plate 12, and this foot 30 is fixed inside the front panel 7 and fitted into a guide member 31. The foot 30 may be plate-shaped or rod-shaped. The receiver 29 can also be fixed to the outer surface or top surface of the front panel 7 with screws or the like.

[0079] (4) Summary of the first embodiment In this embodiment, the table board 9 is attached to the front panel 7 that protrudes forward of the seat part 3, and therefore, as shown in FIG. 2, the table board 9 is disposed in front of the seat 1. Therefore, people can easily sit down and leave the chair portion 3 without changing the position of the table top 9. Therefore, it is easy to use.

[0080] In addition, the seated person Panels 4-7, 11 Since the space is enclosed on almost three sides by chairs, it has a moderate degree of closedness, creating an environment where people can concentrate on their work. Moreover, the area in front of the seated person is open, providing an open environment where superiors and colleagues can easily speak to them (from the superior's perspective, it is easy to keep track of the work status and is also excellent for management). The harmony between this closed and open nature creates an environment where concentration and stimulation can be balanced, and intellectual productivity can be increased.

[0081] In addition, the position of the table board 9 can be adjusted forward and backward, so that the position of the table board 9 can be changed according to the tilt of the seated person's upper body, for example, so that the position can be set to make it easier for the person to operate a laptop computer or the like.

[0082] For example, when a seated person operates a laptop computer in an upright position, they typically tilt their head slightly forward and tilt the laptop monitor toward them relative to the vertical line (i.e., away from them), and the monitor is often positioned so that the person's line of sight is generally perpendicular to the screen.

[0083] On the other hand, when a seated person leans back, the height of the head lowers and the position of the eyes also lowers, so if the monitor is simply moved back in parallel without changing posture, the monitor will be viewed from below the perpendicular to the screen, which may result in poor visibility of the text, etc. In this regard, it may be possible to change the angle of the monitor according to the backward lean of the body, but it is a hassle to have to reach for the monitor every time to adjust the angle.

[0084] In contrast, in this embodiment, when the table board 9 is pulled toward the body in accordance with the backward tilt of the body, the table board 9 While changing the height Because the table tilts backward, the monitor of a laptop computer placed on the table top 9 also tilts at a smaller angle relative to the vertical, and therefore the relationship between the monitor and the line of sight is automatically maintained in an appropriate state so that the person's line of sight is kept approximately perpendicular to the screen. This is therefore user-friendly. Connecting the support column 8 to the front panel 7 near the floor, as in the embodiment, is particularly preferable because it increases the pivot span of the support column 8 and makes it easier to match the degree of backward tilt of the body.

[0085] In addition, since the pivot point of the support 8 is located below the table board 9, the height of the table board 9 remains the same even when the support 8 rotates. Although it changes The height is not too low, so a person can operate the notebook computer with their hand naturally extended. This is also one of the major advantages of this embodiment.

[0086] In this embodiment, the rear end of the rearward-facing portion 8b of the support column 8 is rotatably connected to the front panel, and as shown in Figure 4(A), the connecting portion of the support column 8 is located almost directly below the rear end of the table top 9. As can be easily seen from Figure 5(A), when the table top 9 tilts backward, its front end first rises and then descends. Therefore, when viewed as a whole, the table top 9 tends to tilt backward with almost no change in height, and therefore the table top can be tilted backward by a large amount without impairing the operability of the notebook computer.

[0087] It is also possible to extend the rearward-facing portion 8b of the support column 8 further rearward than shown in the figure and connect its rear end to the rear end of the front panel 7. In this case, the table top 9 can be raised when the chair is tilted backward.

[0088] In order to position the pivot point of the support pillar 8 below the rear end of the table top 9, the support pillar 8 does not have to be L-shaped. It may be straight and upright without a horizontal section at the bottom, or it may be straight and tilted forward. Contrary to the embodiment, the support pillar can be L-shaped with a forward-facing section at the bottom of the base 8a, and the base 8a can be positioned near the rear end of the table top 9. This also increases stability when the base 8a is upright. The support pillar 8 can be formed into a plate-like shape with a large front-to-rear width (for example, a plate-like shape with a width approximately half the front-to-rear width of the table top 9), and the bottom of the rear end can be connected to the front panel 7.

[0089] It is also possible to attach the bracket 20 to the upper end of the support column 8 so that it can rotate back and forth, allowing the table board 9 to be adjusted to any angle at any forward or backward position.

[0090] In this embodiment, the furniture is open above, and Top Panel Since the floor 11 and the front partition 12 are translucent, work can be done using the floor lighting without the need for dedicated lighting, but if a brighter environment is desired, a separate lamp can be installed. Top Panel11 or the front partition plate 12. Top Panel It is also possible to provide the front partition plate 11 and the front partition plate 12 with a surface emitting material such as an organic EL film.

[0091] Although not shown, bottom The side panels 4, 5 and the front panel 7 can be provided with power outlets, USB ports for charging mobile phones, smartphones, and tablet devices, LAN ports, and the like. bottom It is also possible to incorporate a wireless power transmitter into the upper surfaces of the side panels 4 and 5, the front panel 7, or the table top 9.

[0092] Power outlets and the like can be provided symmetrically in the front and rear directions, for example, on the top or side of the front panel 7 (the side below the table top 9). In this way, even if one front panel 7 is placed between the front and rear furniture pieces when two pieces of furniture are placed facing each other as shown in Figures 3(A) and 3(B), each person approaching can access power from one front panel 7. In other words, one front panel 7 can also be used as a power supply means for the people facing each other.

[0093] The height of the front panel 7, bottom By making the front panel 7 slightly higher than the side panels 4 and 5, the upper part of the front and rear bottom If the front panel 7 is exposed on the side panels 4, 5 and an outlet, LAN port, USB port, etc. is provided on the exposed front and rear surfaces, the outlet, LAN port, etc. will face the user, making it even more user-friendly and preventing a reduction in the area available for placing items. Note that if one front panel 7 is shared by furniture in the front and rear, it is preferable to position the table top 9 symmetrically from front to back.

[0094] If a power supply means such as an outlet is provided on each of the left and right sides of the front panel, when two pieces of furniture are placed in opposite orientations but shifted left and right rather than facing each other, as shown in Figures 3(C)(D), (E)(F), even if only one front panel 7 is placed between the two pieces of furniture, the single front panel 7 can be shared by the two pieces of furniture as a means of power supply, etc.

[0095] (4) Second embodiment FIG. 5(B) shows an example in which the chair portion 3 has a reclining structure (or a rocking structure). In this embodiment, the seat 1 has two bottom The seat 1 is supported by longitudinal support rails 33 provided on the side panels 4 and 5, and is divided into front and rear sections so as to bend around a hinge section 34, with the front section 1a and rear section 1b supported by the support rails 33 via front and rear sliders 35 and 36, and the portion of the support rail 33 where the front slider 35 is attached is inclined forward.

[0096] Therefore, when the seat 1 moves forward, the rear portion 1b moves forward without changing its position, but the front portion 1a moves forward while changing its position downward. The lower end of the backrest 2 is connected to the rear end of the seat 1 by a hinge 37. Both the seat 1 and the backrest 2 have a structure in which a cushion is stretched over an inner shell made of resin or the like, and a hinge 34 is formed in the inner shell of the seat 1 by forming a slit or the like.

[0097] The sliders 35 and 36 are biased backward by springs, and when the seated person leans against the backrest 2, the backrest 2 tilts backward against the spring, and the seat 1 moves forward. In this way, by adopting a reclining structure for the chair part 3, the user can operate the laptop computer in a comfortable position, which can make it easier to come up with good ideas. Top Panel 11, you can recline without worrying about being seen by others. Therefore, it is also suitable for women.

[0098] Needless to say, various reclining structures can be adopted. When the seat 1 is configured as a bending type, it is also possible to adopt a configuration in which the front part 1a moves forward without changing its posture and the rear part 1b tilts backward. Of course, the seat 1 may simply move forward, or only the backrest 2 may tilt backward.

[0099] (5) Third to Sixth Embodiments Fig. 6(A) shows a third embodiment. In this embodiment, the support 8 is of an expandable type in which an outer tube 38 and an inner member 39 are fitted together, and the inner member 39 is connected to the front panel 7, and the table board 9 is fixed to the outer tube 38. There is an appropriate amount of friction between the outer tube 38 and the inner member 39, and when a certain amount of force is applied to push or pull the table board 9, the height of the table board 9 can be adjusted. Large The table top 9 will not slide down during normal use.

[0100] The lower end of the support pillar 8 is rotatably connected to the front panel 7, and the connecting part is provided with an unlock button 40 that moves left and right along the rotation axis. When the unlock button 40 is pressed toward the front panel 7 with the foot, the lock is released and the table top 9 can be rotated back and forth. When the foot is removed from the unlock button 40, the support pillar 8 is held in that rotated position. In other words, when the unlock button 40 is pressed, the movable locking member and the fixed locking member are disengaged, and when pressure on the unlock button 40 is released, the movable locking member is pushed by a spring and engages with the fixed locking member.

[0101] If the support pillar 8 is long, there is a concern that the table top 9 may become unstable. Therefore, in this embodiment, the stability of the table top 9 is also taken into consideration. That is, a guide groove 41 (or a guide means such as a guide body) with a radius of curvature centered on the pivot point of the support pillar 8 is provided on the inner surface of the upper part of the front panel 7, and a slider 42 is provided on the upper end of the support pillar 8, which fits slidably and cannot come out of the guide groove 41. The outer cylinder 38 is fitted to the slider 42 so as to be able to move up and down.

[0102] 6(B), a guide groove 41 (or guide body) curved concavely downward is provided on the upper inner surface of the front panel 7, while a slider 42 is attached to the bracket 20 to which the table plate 9 is fixed, so that it can slide freely and cannot come off the guide groove 41. The guide groove is formed in an arc shape with a radius of curvature centered on the lower end of the front panel 7, but it may also be linear in a backward tilted position.

[0103] As shown in Figure 7(A) First reference example In this example, a guide groove 41 (or guide body) is provided in the front panel 7, and a slider 42 is attached to this guide groove 41 so that it cannot be removed and can slide freely back and forth. A bracket 20 is attached to the slider 42 so that it can rotate back and forth, and a table plate 9 is fixed to the bracket 20. Therefore, the position of the table plate 9 can be adjusted back and forth, and the angle can be adjusted as desired in either the front or back position.

[0104] The first one shown in FIG. 5 In this embodiment, similar to the first embodiment, when a bracket 20 is attached to the upper end of a support column 8 that can rotate back and forth, a table board 9 is attached to the bracket 20 so that it can be flipped up toward the front panel 7. In this embodiment, the front of the seat section 3 can be left wide open, making it easy for people to enter and exit.

[0105] (6) Seventh embodiment In the first embodiment, bottom The side panels 4, 5 and the front panel 7 are formed in a hollow structure having an inner plate and an outer plate. 6 In an embodiment, bottom The side panels 4, 5 and the front panel 7 are formed into a bag structure with no inner panels and a top panel attached to the upper ends of the outer panels. The front panel 7 is provided with a front panel 7a to increase stability.

[0106] In this embodiment, bottom The inside of the side panels 4, 5 and the front panel 7 can be used as a luggage storage area, which has the advantage of increasing the storage capacity of items. bottom It extends to the outer plates of the side panels 4 and 5. Therefore, luggage such as bags and documents, or clothes such as coats can be placed on the seat 1.

[0107] In this embodiment, the chair portion 3 can also be made reclining, but in this case, it is possible to make the entire seat 1 movable, or it is also possible to make only the portion corresponding to the backrest 2 movable, as shown by the dashed dotted line. If only the portion corresponding to the backrest 2 is made movable, the seat 1 is naturally divided into three parts, left and right.

[0108] No. 6 In this embodiment, the table plate 9 is attached to the upper end of a support column 8 that pivots back and forth via a bracket 20 and a spacer 44. The support column 8 is in the form of a plate, and a pin 45 is rotatably connected to the inner surface of the outer plate of the front panel 7. Since the bracket 30 is inserted inside the front panel 7, the table plate 9 is fixed to the bracket 20 via the spacer 44.

[0109] A wide portion 8c is provided at the upper end of the support column 8, and a guide groove 46 with a radius of curvature centered on the pin 45 is formed in this wide portion. Meanwhile, a reinforcing plate 47 that overlaps with the wide portion 8c of the support column 8 in a side view is fixed to the outer plate of the front panel 7, and a guide pin 48 that fits non-detachably into the guide groove 46 is attached to the reinforcing plate 47. A friction ring 49 located between the support column 8 and the reinforcing plate 47 is fitted into the guide pin 48. Therefore, the front-rear position and posture of the table top 9 are maintained by the frictional force of the friction ring 49.

[0110] (7) Eighth to Eleventh Embodiments In Figure 9(A), Second reference example This shows Second reference example So, bottom The side panels 4, 5 and the front panel 7 are configured in a bag-like shape as in Figure 8, but bottom The side panel 4 has an inner plate facing upward cut away above the seat 1 to form an article storage section 50 with an upward opening below the seat 1.

[0111] As shown by the dashed line, bottom It is also possible to hollow out the rear portions of the top plates of the side panels 4 and 5 inward. The table plate 9 can be moved back and forth by the same means as in the case of Fig. 8. In this case, as shown by the dashed line, the table plate 9 may be configured to be able to rotate and flip up towards the front panel 7. In Figs. 8 and 9, Top panel 11 and divider 12 is omitted.

[0112] As shown in Figure 9(B) Third reference example This is a modified example of the embodiment shown in Fig. 8. The difference from the embodiment shown in Fig. 8 is that the table board 9 is set to a height that allows it to fit inside the front panel 7, and is attached to the bracket 20 by guide means 51 such as a linear rail so that it can slide left and right.

[0113] In FIG. 10(A), 7 In this embodiment, first, bottom The side panels 4, 5 and the back panel 6 each have a two-layer structure consisting of an inner layer 4', 5', 6' and an outer layer 4", 5", 6", bottom The outer layers 4" and 5" of the side panels 4 and 5 have sound-permeable openings at the front and top, and a privacy plate 52 such as a resin plate is attached to the opening. The outer layer of the back panel 6 is of a height that surrounds the seated person and is made of an opaque plate material.

[0114] In this embodiment, one bottom A wall plate 53 is attached to the outer surface of the side panel 4 so as to be slidable back and forth, and the front part of the wall plate 54 is bottom The front panel 7 is formed by protruding forward from the side panels 4 and 5. In the figure, a table plate 9 is attached to the front panel 7 via supports 8 so that it can move back and forth freely, but it is also possible to attach the table plate so that it fits inside the thick part of the front panel 7, so that the front panel 7 can be pulled out and then tilted to a horizontal position.

[0115] Alternatively, the table plate can be configured as a separate structure from the front panel 7, and can be detachable from the front panel 7 by combining an engaging hole with an engaging claw, etc. Furthermore, the upper part of the front panel 7 can be configured to be bent inward, and part of the front panel can be used as a table plate.

[0116] Wall panel 53 bottom It is the same height as side panels 4 and 5, bottom The openness is enhanced when the table top 9 is set at the same height as the inner layers 4', 5' of the side panels 4, 5. In this case, the table top 9 can be attached to the front panel 7 in front of the wall panel 53 so that it can be freely moved between a folded, hanging position overlapping the outer surface of the front panel 7 and a horizontal, raised position positioned in front of the seat 1.

[0117] In this and other embodiments, the table board 9 can be connected to the upper end of the support column 8 or the like so as to be horizontally rotatable, if conditions permit.

[0118] In Figure 10(B), 4th reference example This shows Reference example So, bottom The side panels 4, 5 and the front panel 7 are configured as a bag structure, and on the side where the table board 9 is not attached, as in FIG. 9(A), bottom An upwardly opening article storage section 50 is formed in the side panel 4. Reference example As a feature of this product, the table board 9 is not attached. bottom The front half of the side panel 4 is cut away above the seat 1, so that people can easily enter and exit the furniture from the side.

[0119] Also, This reference example In the example, the table plate 9 is attached to a slide frame 54 having legs 54a, and the slide frame 54 is attached to the front panel 7 so as to be able to move back and forth. Casters 55 such as roller type wheels are attached to the legs 54a of the slide frame 54, so the table plate 9 can be moved back and forth in a stable manner.

[0120] Furthermore, this Reference example In this case, the table board 9 is rotatably attached to the horizontal part of the slide frame 54. Therefore, the posture as seen from the side can be arbitrarily adjusted to any front or rear position. The legs 54a of the slide frame 54 are attached to the left side of the slide frame 54, which is located on the opposite side of the front panel 7. At the bottom It protrudes forward from side panel 4, but bottom The side panel 4 is cut out so that people can easily enter and exit the furniture. The legs 54a of the slide frame 54 do not get in the way of the person's legs while they are working.
