[0027] As shown in Figs. 1, 2, 4, 5 and 7 to 10, the upper slide structure 2 is provided with a pair of stepped floors 25, 26 having a height difference corresponding to the drop g described above. Specifically, the slide structure 2 is provided with a pair of left and right leg bases 21 arranged in parallel, a pair of left and right support columns 22 each erected at the base end (rear end) of the leg bases 21, a rear floor board support frame 23 cantilevered forward from the upper end positions of the support columns 22, a front floor board support frame 24 cantilevered forward from the middle position of the support columns 22, a rear stepped floor 25 provided on the rear floor board support frame 23, and a front stepped floor 26 provided on the front half of the front floor board support frame 24. The leg base 21 is provided with rolling elements 211 such as wheels that roll in the front-rear direction. The left and right support columns 22 are each a rectangular pipe and are rigidly connected to each other by a lower cross member 27 and an upper cross member 28. The upper cross member 28 is a channel-like member that is open to the front, and both ends of the upper cross member 28 are located near the side ends of the tabletop 4.

[0028] 2, 5, 8 and 10, the front floor board support frame 24 is long and its front half extends forward from the front end 23a of the rear floor board support frame 23, with a first support leg 241 provided at the front end and a second support leg 242 provided in the middle. Each support leg 241, 242 hangs down from the front floor board support frame 24 and has a rolling element 243 at its lower end. The front end 23a of the rear floor board support frame 23 is rigidly connected to the middle position of the front floor board support frame 24 via a vertical frame 231. Reference numeral 29 denotes a front curtain board and 20 denotes a rear curtain board.

[0029] As shown in Figs. 1, 2 and 4 to 10, the lower slide structure 3 is provided with a pair of stepped floors 35, 36 having a height difference corresponding to the drop g. Specifically, the slide structure 3 is provided with a pair of left and right leg bases 31 arranged in parallel, a pair of left and right support columns 32 each erected on the base end (rear end) of the leg bases 31, a rear floor support frame 33 cantilevered forward from the upper end positions of the support columns 32, a front floor support frame 34 cantilevered forward from the middle position of the support columns 32, a rear stepped floor 35 provided on the rear floor support frame 33, and a front stepped floor 36 provided on the front half of the front floor support frame 34. The leg base 31 is provided with rolling elements 311 such as wheels that roll in the front-rear direction. The left and right support columns 32 are each in the form of a rectangular pipe and are rigidly connected to each other by an upper cross member 38. The upper cross member 38 is a channel-like member that is open toward the front, and both ends of the channel are positioned near the side ends of the top plate 4.

[0030] 2, 5, 8 and 10, the front floor board support frame 34 is long and its front half extends forward beyond the front end 33a of the rear floor board support frame 33. A vertical frame 341 is provided hanging down from the front end of the front floor board support frame 34, and the lower end of the vertical frame 341 is rigidly connected to the leg base 31. The front end 33a of the rear floor board support frame 33 is rigidly connected to the middle position of the front floor board support frame 34 via the vertical frame 331. Reference numeral 39 denotes a front curtain board, and 30 denotes a rear curtain board.

[0031] The upper sliding structure 2 and the lower sliding structure 3 thus constructed are assembled in a telescopic manner and arranged so as to be able to protrude and retract into the space S1 under the top board of the furniture main body 1, as shown in Figs. 3, 6 and 9. That is, the lower sliding structure 3 is assembled so that the left and right leg bases 31 are positioned inside the left and right leg bases 21 of the upper sliding structure 2 and can slide in the front-rear direction. A stopper 212 is provided at the front end of the leg base 21 of the upper sliding structure 2 to abut against the support 32 of the lower sliding structure 3 and to stop the lower sliding structure 3 from protruding further. The stopper 212 is attached after the lower sliding structure 3 is assembled under the upper sliding structure 2.

[0032] 3, 6 and 9, the upper sliding structure 2 is assembled so that the left and right leg bases 21 are positioned inside the left and right leg bases 11 of the furniture main body 1 and can slide in the front-rear direction. A stopper 112 is provided at the front end of the leg base 11 of the furniture main body 1 to abut against the support column 22 of the upper sliding structure 2 and stop the upper sliding structure 2 from protruding any further. This stopper 112 is also attached after the upper sliding structure 2 is assembled under the furniture main body 1.

[0033] 2, 5 and 8, the furniture T with a tabletop assembled in this manner has height differences corresponding to the aforementioned drop g between the step floors 25, 26, 35, 36 of the adjacent sliding structures 2, 3, and between the highest step floor 25 and the tabletop 4. That is, a common drop g is set between the step floors 25, 26 in front of and behind the upper sliding structure 2, and between the step floors 35, 36 in front of and behind the lower sliding structure 3, and further, dimensions are set so that a height difference the same as the aforementioned common drop g is formed between the step floor 35 behind the lower sliding structure 3 and the step floor 26 in front of the upper sliding structure 2, and between the step floor 25 behind the upper sliding structure 2 and the tabletop 4 of the furniture main body 1. This furniture T with a tabletop can take on a table mode (P) as shown in Figures 1 to 3, a sofa mode (Q1) (first mode aspect of the unfolded mode) as shown in Figures 4 to 6, and a stadium mode (Q2) (second mode aspect of the unfolded mode) as shown in Figures 7 to 9.

[0034] As shown in Figs. 1, 2, 4, 5, 7, 8 and 10, the lower step floors of the slide structures 2 and 3, i.e., the step floor 26 in front of the upper slide structure 2 and the step floor 36 in front of the lower slide structure 3, are provided with sofas 7 having a thickness corresponding to the above-mentioned drop g. As shown in Fig. 7, each step floor 26, 36 is provided with at least one of an aisle area (A) and a seating area (C), and the sofas 7 are provided in the seating area (C). More specifically, in this embodiment, the step floor 36 in front of the lower slide structure 3 has seating areas (C) formed on both sides of the aisle area (A) set in the center, and the sofas 7 are provided in both seating areas (C). The entire area of ​​the step floor 35 behind the lower slide structure 3 is designated as the aisle area (A). A seating area (C) is defined in the center of the step floor 26 in front of the upper sliding structure 2, and aisle areas (A) are formed on both sides of the seating area (C), with a sofa 7 placed in the seating area (C). The entire step floor 26 behind the upper sliding structure 2 is designated as the aisle area (A). When used in stadium mode (Q2), the sofa 7 is also detachably placed over the entire area of ​​the first tabletop portion 41 of the tabletop 4 located behind the aisle area (A).

[0035] Here, FIG. 1 is an overall perspective view showing the furniture with a top T in the table mode (P), FIG. 2 is a right side view, and FIG. 3 is a bottom view. FIG. 4 is an overall perspective view showing the furniture with a top T in the sofa mode (Q1), FIG. 5 is a right side view, and FIG. 6 is a bottom view. FIG. 7 is an overall perspective view showing the furniture with a top T in the stadium mode (Q2), FIG. 8 is a solid line showing the right side view, and FIG. 9 is a bottom view. FIG. 8 shows the furniture with a top T in the table mode (P) with imaginary lines. Also, in FIG. 3, FIG. 6, and FIG. 9, the use end 42a of the second top portion 42 is shown as the right side. FIG. 10 is an exploded perspective view showing the furniture with a top T.

[0036] This furniture T with a tabletop can be used appropriately as a counter table with multiple people using it from both the front and back of the tabletop 4 when it is in table mode (P) with the upper and lower sliding structures 2, 3 retracted under the tabletop 4, creating a flexible work area FA that can utilize the surrounding space for multiple purposes.

[0037] Furthermore, from this state, if only the lower sliding structure 3 is advanced forward and protruded to change the configuration to sofa mode (Q1), the lower sliding structure 3 can be used as a sofa 7. This makes it possible to create a refreshment lounge area RA where low-concentration work can be done or a small number of people can communicate. Figure 11 shows an example of creating a refreshment lounge area RA by placing furniture T with a tabletop set to sofa mode (Q1) in a corner of the office space OS.

[0038] Furthermore, when the upper sliding structure 2 and the lower sliding structure 3 are fully extended forward relative to the furniture body 1 to change to stadium mode (Q2), the top plate 4 of the furniture body 1 and the step floors 25, 26, 35, 36 of each sliding structure 2, 3 will unfold in a staircase shape. This makes it possible to create a collaboration area CA where events such as open innovation seminars can be held with a limited number of participants.

[0039] Figure 12 shows an example of creating a flexible work area FA by placing furniture with a top set to table mode (P) in a corner of the office space OS, and creating a collaboration area CA next to it by placing furniture with a top set to stadium mode (Q2) where seminars and other events can be held.

[0040] With furniture T with a tabletop having such a configuration, the basic form can be changed significantly, and this change can accommodate changes in use that could not be accommodated with conventional dedicated furniture. Therefore, a single type of furniture with a tabletop T can provide the same usability as preparing multiple types of dedicated furniture and replacing them as needed. Moreover, with such furniture, the basic form can be changed simply by sliding the sliding structures 2 and 3 relative to the furniture body 1, so there is no need for the effort and time required to replace dedicated furniture.

[0041] In addition, in this embodiment, a plurality of sliding structures 2, 3 with step floors 25, 26, 35, 36 of different heights are arranged in a telescopic manner. Although a vast tiered form can be realized when deployed, these sliding structures 2, 3 can be stored compactly under the top plate 4 of the furniture body 1, making it possible to realize dynamic changes to the basic form.

[0042] Furthermore, since each of the slide structures 2, 3 is provided with a pair of step floors 25, 26, 35, 36 having a height difference corresponding to the aforementioned drop g, it is possible to realize a staircase configuration that is easy to move around in while keeping the number of slide structures 2, 3 to a minimum, thereby preventing an increase in the number of parts and a complicated structure.

[0043] In this case, if a sofa 7 with a thickness corresponding to the staircase drop g is placed on the lower step (front step 26, 36) of each sliding structure 2, 3 as described above, the sliding structures 2, 3 can be telescopically operated without removing the sofa 7, minimizing the effort required for changing modes.

[0044] Of course, the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0045] For example, in the above embodiment, the case has been described where two types of mode configurations are provided as the deployment mode, but the deployment mode may be only one of either the sofa mode or the stadium mode.

[0046] Furthermore, the number of types of the sliding structure is not limited to two, but may be one type or three or more types. By increasing the number of types of the sliding structure, it is possible to further increase the number of deployment modes.

[0047] In the illustrated example, each slide structure has a pair of step floors with a height difference, but each slide structure may have only one step floor or three or more step floors. However, if each slide structure has a pair of step floors with a height difference as in the illustrated example, as described above, it is possible to realize a staircase shape that is easy to move around in while minimizing the number of slide structures, and it is possible to prevent an increase in the number of parts and a complicated structure.

[0048] In addition, in the illustrated example, each floor step is provided with an aisle area and a seating area, and sofas are arranged in the seating areas in advance, but for example, all floor steps may be made into an aisle shape, and sofas may be placed in any desired location so that people can sit freely. However, if the seating areas are determined in advance as in the illustrated example, it is possible to obtain the effect of making it easier to optimize the design of the aisle.

[0049] In addition, the top plate of the furniture body is not limited to one having a first top plate portion and a second top plate portion, and may be, for example, a single piece. However, if the fixing position of the first top plate portion can be changed as in the illustrated example, it is possible to obtain an advantage that in the table mode, a space for the lower legs can be effectively formed on both the front and rear sides of the top plate, and in the unfolded mode, the first top plate portion can be retracted so as not to get in the way.

[0050] The height of the tabletop is not limited to 800mm to 1050mm from the floor, but if it is set within this range, it is possible to obtain the effect of being able to store multiple slide structures without sacrificing usability. In other words, if it is set below 800mm, it becomes difficult to store two or more slide structures, and if it exceeds 1050mm, many users will find it difficult to use even in a standing position because it is too high.

[0051] In addition, side panels may be provided to hide the space below the tabletop or the step floor from the side spaces, and means such as handrails may be provided to prevent a user seated on the tabletop or the step floor of the upper sliding structure from falling. The side panels and handrails may be attached after the mode is changed, or may be attached in advance to the sides of the furniture body and the sides of each sliding structure. In this case, the side panels and handrails must be attached so that they do not interfere with each other when the sliding structures slide.

[0052] The width of the entire furniture with a tabletop is not limited to that shown in the figure, and may be modified in various ways. In addition, a plurality of furniture with a tabletop according to the present invention having a predetermined width may be connected together in the width direction for use.

[0053] In addition, various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
