Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, depending on the work style of the worker, there are cases where it is desired to secure a work environment that is conducive to concentration with the partition panel, and cases where, for example, communication with other workers is desired. However, if one moves away from the desk (furniture with a liftable top plate) to another location for communication with other workers, the work efficiency may decrease. For this reason, a furniture with a liftable top plate that can be used in more diverse forms is desired. An object of the present invention is to provide a furniture with a liftable top plate that can be used in more diverse forms and enhance the convenience for users.

Means for Solving the Problems

[0005] To solve the above problems, the present invention employs the following embodiments. (1) A liftable top-mounted furniture according to one aspect of the present invention comprises a top-mounted tabletop having an upward-facing work surface, a support structure that supports the top-mounted tabletop so that it can be raised and lowered vertically, and a panel member that can be raised and lowered integrally with the top-mounted tabletop and protrudes above the top-mounted tabletop to partition the space above the top-mounted tabletop and the space outside the top-mounted tabletop, wherein the top-mounted tabletop integrally comprises a first portion of the top-mounted tabletop extending in a first extending direction in the horizontal direction, and a second portion of the top-mounted tabletop extending from a part of the first portion of the top-mounted tabletop in a second extending direction different from the first extending direction in the horizontal direction, and the panel member comprises a first panel portion that extends in the first extending direction so as to be along at least a part of the rear edge of the top-mounted tabletop located on the rear side of the first depth direction which is the depth direction of the top-mounted tabletop. In this embodiment, the first panel portion is provided so as to be along at least a part of the rear edge of the first portion of the tabletop. Therefore, by positioning oneself on the front side of the first portion of the tabletop in the first depth direction, the user can partition the space above the tabletop and the space outside the tabletop in front of them, thereby ensuring a work environment that facilitates concentration. On the other hand, the tabletop includes a second portion of the tabletop that extends from a part of the first portion of the tabletop in a second extension direction different from the first extension direction, which is the extension direction of the first portion of the tabletop. Therefore, by facing the direction towards the second portion of the tabletop and positioning oneself on the front side of the second portion of the tabletop in the second depth direction, the user can face another person positioned on the rear side in the second depth direction, with the second portion of the tabletop in between. Thus, while using a single tabletop height-adjustable furniture, it is possible to obtain both a work environment that facilitates concentration and an environment that allows for communication with other people. Furthermore, since the panel components can be raised and lowered together with the tabletop, the panel components can be raised and lowered along with the tabletop when the tabletop is raised or lowered. This allows the user to maintain a tabletop height that is easy to work at, and to always maintain a work environment that is easy to concentrate on, as well as an environment that allows for communication with others. As a result, it can be used in a wider variety of forms, increasing convenience for users.

[0006] (2) In the liftable top shelf furniture according to the embodiment of (1) above, it is preferable that the space above the second portion of the top shelf is open on both sides in the second depth direction, which is the depth direction of the top shelf of the second portion of the top shelf. According to this embodiment, since the space above the second portion of the tabletop is open on both sides in the second depth direction, communication with other people facing each other across the second portion of the tabletop, and the exchange of items via the work surface of the second portion of the tabletop, can be carried out smoothly.

[0007] (3) In a tabletop lifting type furniture according to the embodiment of (1) or (2) above, the first portion of the tabletop is provided with a side edge at at least one end in the first extending direction, extending from the rear edge to the front in the first depth direction, and the panel member further comprises a second panel portion that extends in the first depth direction along at least a part of the side edge and is connected to the first panel portion at the rear in the first depth direction. According to this embodiment, by providing a second panel along at least a portion of the side edge of the first part of the tabletop, it is possible to partition the space above the tabletop and the space outside the tabletop on the side where the second panel is provided, as viewed from the user, thereby ensuring a work environment that facilitates concentration.

[0008] (4) In a tabletop lifting type furniture according to any of the embodiments of (1) to (3) above, it is preferable that the first panel portion is provided along the entire area of ​​the first extending direction at the rear edge. According to this embodiment, by providing the first panel along the entire area of ​​the first extending direction of the rear edge, it is possible to partition the entire space above the tabletop from the space outside the tabletop at the front as seen from the user's perspective. Furthermore, if a wall is located in front of the user, the first panel will be positioned between the rear edge of the first part of the tabletop and the wall, which helps to prevent objects, fingers, etc. from getting caught between the rear edge of the first part of the tabletop and the wall.

[0009] (5) In a tabletop lifting type furniture according to any of the embodiments of (1) to (4) above, it is preferable that the panel member has a skirt portion that extends downward from the tabletop. According to this embodiment, the panel member having a skirt portion allows for a partition between the space below the tabletop and the space outside the tabletop. This makes it difficult to see the user's lower limbs or items placed below the tabletop from the space outside the tabletop.

[0010] (6) In a tabletop lifting type furniture according to any of the embodiments of (1) to (5) above, the furniture further comprises an operating unit for raising and lowering the tabletop, wherein the operating unit is preferably provided on the lower side of the front edge located on the front side in the first depth direction of the first portion of the tabletop. In this embodiment, since the control unit is located on the underside of the front edge of the first portion of the top panel, the control unit will be operated by a user positioned on the front side of the first portion of the top panel in the first depth direction. Therefore, it is possible to prevent other people from unintentionally operating the control unit. [Effects of the Invention]

[0013] Hereinafter, with reference to the accompanying drawings, a mode for implementing the top plate lifting furniture according to the present invention will be described. However, the present invention is not limited to only this embodiment.

[0014] (Top plate lifting furniture) FIG. 1 is a perspective view showing a top plate lifting furniture 100 according to this embodiment. As shown in FIG. 1, the top plate lifting furniture 100 is disposed on the floor surface F of a work space in an office, a public facility, or the like. The top plate lifting furniture 100 includes a top plate 10, a support structure 20, and a panel member 50. In the following description, the direction perpendicular to the floor surface F is referred to as the vertical direction Dv, the direction in which the first part 11 of the top plate described later extends in the horizontal direction is referred to as the first extending direction D1, and the direction intersecting the first extending direction D1 in the horizontal direction is referred to as the first depth direction D1a. Further, the direction in which the second part 12 of the top plate described later extends in the horizontal direction is referred to as the second extending direction D2, and the direction intersecting the second extending direction D2 in the horizontal direction is referred to as the second depth direction D2a.

[0015] (Top plate) FIG. 2 is a view of the top plate lifting furniture 100 according to this embodiment as seen from above. The top plate 10 is plate-shaped and extends along a plane intersecting the vertical direction Dv, and has a work surface 10f facing upward. As shown in FIGS. 1 and 2, the top plate 10 is formed in an L shape, for example, when viewed from above. The top plate 10 integrally includes a first part 11 of the top plate and a second part 12 of the top plate.

[0016] The first part 11 of the top plate extends in the first extending direction D1 in the horizontal direction. The first part 11 of the top plate is formed in a rectangular shape having the first extending direction D1 as the longitudinal direction and the first depth direction D1a as the short side direction when viewed from above.

[0017] The first part 11 of the top plate has a rear edge 11r, side edges 11s and 11t, and a front edge 11f. The rear edge 11r extends in the first extension direction D1 at the rear of the first depth direction D1a of the first portion 11 of the top plate. The rear edge 11r constitutes the first outer edge 10e1 of the top plate 10, which extends linearly in the first extension direction D1 at the rear of the first depth direction D1a.

[0018] The side edge 11s extends from the rear edge 11r to the front side of the first depth direction D1a at one end of the first portion 11 of the top plate in the first extending direction D1. The side edge 11t extends from the rear edge 11r to the front side of the first depth direction D1a at the other end of the first portion 11 of the top plate in the first extending direction D1. The side edges 11s and 11t extend parallel to each other. The front side edge 11f extends parallel to the rear edge 11r in the first extending direction D1 at the front side of the first depth direction D1a of the first portion 11 of the top plate, except for the part to which the second portion 12 of the top plate (described later) is connected.

[0019] As shown in Figures 1 and 2, the second portion 12 of the top plate extends from a part of the first portion 11 of the top plate in a second extending direction D2 that is different from the first extending direction D1 in the horizontal direction. In this embodiment, the second portion 12 of the top plate extends from one end of the first portion 11 of the top plate in the first extending direction D1 to one end in the second extending direction D2. In other words, the other end of the second portion 12 of the top plate in the second extending direction D2 is connected to the first portion 11 of the top plate. In this embodiment, the first extending direction D1 and the second extending direction D2 are perpendicular to each other.

[0020] The second portion 12 of the top plate is formed in a rectangular shape, for example, when viewed from above. In this embodiment, the second portion 12 of the top plate is formed in a rectangular shape with the second extending direction D2 as the longitudinal direction and the second depth direction D2a, which intersects the second extending direction D2 in the horizontal direction, as the short direction.

[0021] The second portion 12 of the top plate has a first edge 12a, a second edge 12b, and a third edge 12c. The first edge 12a is on the first side of the second depth direction D2a of the second portion 12 of the top plate and extends in the second extension direction D2. The first edge 12a and the front edge 11f are continuously connected, for example, via an arc-shaped edge 12r when viewed from above. In this embodiment, "continuous" means without steps or corners. The second edge 12b extends in the second extension direction D2 parallel to the first edge 12a on the second side of the second depth direction D2a of the second portion 12 of the top plate, and is located parallel to the first edge 12a. The second edge 12b extends continuously to the side edge 11s of the first portion 11 of the top plate. The second edge 12b and the side edge 11s constitute the second outer edge 10e2 of the top plate 10, which extends linearly in the second extension direction D2 on the second side of the second depth direction D2a. The third edge 12c connects the first edge 12a and the second edge 12b at one end of the second portion 12 of the top plate in the second extending direction D2. In this embodiment, the third edge 12c extends linearly in the second depth direction D2a. In this embodiment, the angle between the first extending direction D1, in which the first portion 11 (first outer edge 10e1) of the top plate extends, and the second extending direction D2, in which the second portion 12 (second outer edge 10e2) of the top plate extends, is, for example, 90°. Therefore, the first extending direction D1 and the second depth direction D2a coincide, and the second extending direction D2 and the first depth direction D1a coincide.

[0039] (Panel component) As shown in Figure 1, the panel member 50 protrudes above the top plate 10, thereby separating the space above the top plate 10 S1 from the space outside the top plate 10 Sa. As shown in Figures 1 and 2, the panel member 50 has a first panel section 51 and a pair of second panel sections 52 and 53. Each of the first panel section 51 and the second panel sections 52 and 53 is made of, for example, metal or resin and is formed in the shape of a plate. The space outside Sa is the area located outside the outer shape of the top plate 10 when viewed from above. Of the space outside Sa, the portion enclosed by the front edge 11f and the first edge 12a is designated as the user workspace Sa1, and the space other than the user workspace Sa1 is designated as the lateral space Sa2.

[0040] The first panel portion 51 extends in the first extending direction D1 along at least a portion of the rear edge 11r of the first portion 11 of the top plate. In this embodiment, the first panel portion 51 is provided along the entire area of ​​the first extending direction D1 at the rear edge 11r. The first panel portion 51 is attached to the lower surface of the first portion 11 of the top plate via a bracket 55 (see Figure 2). The first panel portion 51 is provided with a gap in the first depth direction D1a between it and the rear edge 11r of the first portion 11 of the top plate.

[0041] The second panel portion 52 extends in the first depth direction D1a along at least a portion of the side edge 11s of one end 11B in the first extending direction D1 of the first top plate portion 11. The second panel portion 52 is connected to the first panel portion 51 at the rear side in the first depth direction D1a. In this embodiment, the second panel portion 52 is provided only on a portion of the side edge 11s at the rear side in the first depth direction D1a. That is, the front end of the side edge 11s in the first depth direction D1a is exposed to the outer space Sa. However, the second panel portion 52 may be provided to cover the entire area of ​​the side edge 11s in the first depth direction D1a. The second panel portion 52 is attached to the lower surface of the first top plate portion 11 via a bracket (not shown). The second panel portion 52 may be provided with a gap in the first extending direction D1 between it and the side edge 11s.

[0042] The other second panel portion 53 extends in the first depth direction D1a along at least a portion of the side edge 11t of the other end 11A in the first extending direction D1 of the first top plate portion 11. The second panel portion 53 is connected to the first panel portion 51 at the rear side in the first depth direction D1a. In this embodiment, the second panel portion 53 is provided only on a portion of the side edge 11t at the rear side in the first depth direction D1a. That is, the front end of the side edge 11t in the first depth direction D1a is exposed to the outer space Sa. The second panel portion 53 may be provided to cover the entire area of ​​the side edge 11t in the first depth direction D1a. The second panel portion 53 is attached to the lower surface of the first top plate portion 11 via a bracket (not shown). The second panel portion 53 may be provided with a gap between it and the side edge 11t.

[0043] Furthermore, the panel members 50 (first panel section 51, second panel sections 52, 53) have a skirt section 50s that extends downward from the top plate 10.

[0044] At the other end of the first portion 11 of the top plate in the first extending direction D1, an operating section 95 is provided on the underside of the front edge 11f. The operating section 95 is fixed to the underside of the first portion 11 of the top plate. The operating section 95 can be operated by a user facing the front edge 11f in the user workspace Sa1. However, the operating section 95 can be provided at any position and in any number on the top plate 10.

[0045] Thus, the panel members 50, each consisting of a first panel section 51 and second panel sections 52 and 53 attached to the tabletop 10, can be raised and lowered together with the tabletop 10. In the tabletop lifting type furniture 100, when a user operates the control unit 95 (see Figure 1), the first leg member 21, the second leg member 22, and the third leg member 23 extend and retract synchronously, causing the tabletop 10 and the panel members 50 to rise and lower together.

[0046] Thus, in this embodiment, the liftable top shelf 100 comprises a top shelf 10 having an upward-facing work surface 10f, a support structure 20 that supports the top shelf 10 so that it can move up and down in the vertical direction Dv, and a panel member 50 that can move up and down integrally with the top shelf 10 and protrudes above the top shelf 10, thereby partitioning the space above the top shelf 10 S1 and the space outside the top shelf 10 Sa, and the top shelf 10 extends in the first horizontal direction The panel member 50 integrally comprises a first top plate portion 11 extending in D1, and a second top plate portion 12 extending from a part of the first top plate portion 11 in a second extending direction D2 that is different from the first extending direction D1 in the horizontal direction. The panel member 50 is configured to include a first panel portion 51 that extends in the first extending direction D1 so as to be along at least a part of the rear edge 11r of the top plate 10 located on the rear side of the first depth direction D1a, which is the depth direction of the top plate first portion 11. In this configuration, the first panel portion 51 is provided so as to follow at least a part of the rear edge 11r of the first portion 11 of the tabletop. Therefore, in the user workspace Sa1, by positioning on the front side of the first depth direction D1a of the first portion 11 of the tabletop, the user can partition the space above the tabletop 10 S1 and the space outside the tabletop 10 Sa (lateral space Sa2) in front of the user, thereby ensuring a work environment that facilitates concentration. On the other hand, the tabletop 10 includes a second portion 12 of the tabletop that extends from a part of the first portion 11 of the tabletop in a second extension direction D2 different from the first extension direction D1. Therefore, in the user workspace Sa1, by facing the direction towards the second portion 12 of the tabletop and positioning on the first side (front side) of the second depth direction D2a of the second portion 12 of the tabletop, the user can face another person positioned on the second side (rear side) of the second depth direction D2a, which is the tabletop depth direction of the second portion 12 of the tabletop, in the lateral space Sa2, with the second portion 12 of the tabletop between them. Therefore, by using a single height-adjustable tabletop furniture unit 100, it is possible to obtain both a work environment conducive to concentration and an environment that allows for communication with others. Furthermore, since the panel member 50 can be raised and lowered together with the tabletop 10, when the tabletop 10 is raised or lowered, the panel member 50 can also be raised or lowered together with the tabletop 10. This allows the user to always have a work environment that is easy to concentrate on, as well as an environment that allows for communication with others, at a tabletop 10 height that is easy for the user to work at. As a result, it can be used in a wider variety of forms, increasing convenience for users.

[0047] In this embodiment, the space S2 above the second portion 12 of the top plate is open on both sides in the second depth direction D2a, which is the depth direction of the second portion 12 of the top plate. With this configuration, the space S1 above the second part 12 of the tabletop is open on both sides in the second depth direction D2a, so that communication with other people facing each other across the second part 12 of the tabletop, and the exchange of items via the work surface 10f of the second part 12 of the tabletop can be carried out smoothly.

[0048] In this embodiment, the first top plate portion 11 has side edges 11s and 11t extending from the rear edge 11r to the front side of the first depth direction D1a at at least one end in the first extending direction D1, and the panel member 50 further includes second panel portions 52 and 53 that extend in the first depth direction D1a along at least a portion of the side edges 11s and 11t and are connected to the first panel portion 51 at the rear side of the first depth direction D1a. With this configuration, by providing the second panel sections 52 and 53 along at least a portion of the side edges 11s and 11t of the first section 11 of the tabletop, it is possible to partition the space above the tabletop 10 S1 and the space outside the tabletop 10 Sa, thereby ensuring a work environment conducive to concentration.

[0049] In this embodiment, the first panel portion 51 is provided along the entire area of ​​the first extending direction D1 at the rear edge 11r. With this configuration, by providing the first panel section 51 along the entire area of ​​the first extending direction D1 of the rear edge 11r, it is possible to partition the entire upper space S1 of the top plate 10 from the outer space Sa of the top plate 10 in front of the user. Furthermore, if a wall is located in front of the user, the first panel portion 51 will be positioned between the rear edge 11r of the first portion 11 of the tabletop and the wall, thereby preventing items, fingers, etc. from getting caught between the rear edge 11r of the first portion 11 of the tabletop and the wall.

[0050] In this embodiment, the panel member 50 has a skirt portion 50s that extends downward from the top plate 10. With this configuration, the panel member 50 has a skirt portion 50s, which allows it to partition the space below the tabletop 10 from the space outside the tabletop 10 Sa. As a result, the user's lower limbs and items placed below the tabletop 10 are less visible from the space outside the tabletop 10 Sa.

[0051] In this embodiment, the tabletop lifting type fixture 100 further includes an operating unit 95 for raising and lowering the tabletop 10, and the operating unit 95 is provided on the lower side of the front edge 11f located on the front side of the first portion 11 of the tabletop in the first depth direction D1a. With this configuration, the control unit 95 is located on the underside of the front edge 11f of the first portion 11 of the top plate. Therefore, the control unit 95 will be operated by a user positioned on the front side of the first depth direction D1a of the first portion 11 of the top plate. Consequently, it is prevented for someone other than the user to inadvertently operate the control unit 95.

[0052] (Modified examples of the embodiment) In the above embodiment, the planar shape of the top plate 10 is L-shaped, where the first extending direction D1 of the first portion 11 of the top plate and the second extending direction D2 of the second portion 12 of the top plate are perpendicular to each other, but it is not limited to this. The planar shape of the top plate 10 may be V-shaped, where the intersection angle between the first extending direction D1 of the first portion 11 of the top plate and the second extending direction D2 of the second portion 12 of the top plate is less than 90° or 90° or more.

[0053] Figure 4 is a plan view showing a modified example of this embodiment of a tabletop lifting type furniture unit 100. Alternatively, as shown in Figure 4, for example, the top plate 10D may be shaped like a T when viewed from above, and may include a first top plate portion 11D extending in a first extending direction D1, and a second top plate portion 12D extending in a second extending direction D2 from the middle of the first top plate portion 11D in the first extending direction D1. In a tabletop lifting type furniture 100 equipped with such a tabletop 10D, the panel member 50D may include a first panel portion 51 that extends along at least a part of the rear edge 11r of the first portion 11E of the tabletop.

[0054] Figure 5 is a plan view showing a liftable tabletop furniture unit 100 in another modified example of this embodiment. Alternatively, as shown in Figure 5, for example, the top plate 10E may be made arc-shaped when viewed from above, with one side in the top plate extension direction (circumferential direction around the center of curvature of the arc) designated as the first top plate portion 11E and the other side as the second top plate portion 12E. In this case, the first top plate portion 11E extends in an arc shape toward one side in the top plate extension direction from the portion J where the first top plate portion 11E and the second top plate portion 12E are connected. The second top plate portion 12E extends in an arc shape toward the other side in the top plate extension direction from the portion J where the first top plate portion 11E and the second top plate portion 12E are connected.

[0055] In such a tabletop 10E, the first virtual line V1 is defined as a line that passes through the center in the depth direction (normal direction to the tabletop extension direction) of the first portion 11E of the tabletop and extends in the tabletop extension direction. The direction in which the tangent to the first virtual line V1 at the center of the first portion 11E in the tabletop extension direction is defined as the first extension direction D1. In addition, the second virtual line V2 is defined as a line that passes through the center in the depth direction (normal direction to the tabletop extension direction) of the second portion 12E of the tabletop and extends in the tabletop extension direction. The direction in which the tangent to the second virtual line V2 at the center of the tabletop extension direction of the second portion 12E is defined as the second extension direction D2. In this case, the first extension direction D1 and the second extension direction D2 extend in different directions from each other. Note that the virtual lines V1 and V2 do not necessarily have to be at the centers of the first extension direction D1 or the second extension direction D2, but may be virtual lines at any point other than part J in the first part 11E and the second part 12E of the top plate.

[0056] In a tabletop lifting type furniture 100 equipped with such a tabletop 10E, the panel member 50E may include a first panel portion 51 that extends along at least a part of the rear edge 11r of the first portion 11E of the tabletop.

The present invention is not limited by the above description, but only by the appended claims. For example, although the configuration of the support structure 20 was described in the above embodiment, the configuration of the support structure 20 can be changed as appropriate, as long as it can support the top plate 10 from below. In the above embodiment, the first reinforcing beam 41 and the second reinforcing beam 42 are connected to the third leg member 23 via the connecting member 30, but the embodiment is not limited to this. The first reinforcing beam 41 and the second reinforcing beam 42 may be connected directly to the third leg member 23 without the connecting member 30.

[0058] In the above embodiment, the planar shape of the top plate 10 is L-shaped, where the first extending direction D1 of the first portion 11 of the top plate and the second extending direction D2 of the second portion 12 of the top plate are perpendicular to each other, but it is not limited to this. For example, the planar shape of the top plate 10 may be V-shaped, where the intersection angle between the first extending direction D1 of the first portion 11 of the top plate and the second extending direction D2 of the second portion 12 of the top plate is less than 90° or greater than 90°.

[0059] In the above embodiment, the second portion 12 of the top plate is rectangular in shape, with the second extending direction D2 as the longitudinal direction and the second depth direction D2a, which intersects the second extending direction D2 in the horizontal direction, as the short direction. However, it is not limited to this. For example, the second portion 12 of the top plate may be rectangular in shape, with the second extending direction D2 as the short direction and the second depth direction D2a as the longitudinal direction. Alternatively, the second portion 12 of the top plate may be square in shape, with the second extending direction D2 and the second depth direction D2a having the same length.

[0060] In the above embodiment, the third end edge 12c of the second portion 12 of the top plate is shown to extend linearly in the second depth direction D2a, but it is not limited to this. The third end edge 12c may be formed in a semi-circular shape, for example.

[0061] In the above embodiment, the first panel section 51 and the second panel sections 52 and 53 are each attached to the top plate 10, but the first panel section 51 and the second panel sections 52 and 53 may also be attached to the support structure 20. Furthermore, in the above embodiment, the panel member 50 comprises a first panel portion 51 and second panel portions 52 and 53. However, the panel member 50 may also comprise only the first panel portion 51 and one of the second panel portions 52 and 53. Alternatively, the second panel portions 52 and 53 may be omitted. In the above embodiment, the second panel portions 52 and 53 are provided only on a portion of the rear side of the side edges 11s and 11t in the first depth direction D1a. However, the second panel portions 52 and 53 may be provided along the entire first depth direction D1a of the side edges 11s and 11t. In the above embodiment, the second panel sections 52 and 53 are connected to the first panel section 51 at the rear end in the first depth direction D1a, but the second panel sections 53 do not necessarily have to be connected to the first panel section 51. Furthermore, without departing from the spirit of the present invention, the components in the embodiments described above can be replaced with well-known components as appropriate, and the modifications described above can be combined as appropriate.
