JP7619066B2 - Furniture with tabletop - Google Patents

Description

The present invention relates to furniture with a tabletop that is suitable for use in shared spaces such as offices and lobbies.

Conventionally, counter-type tables that can be used by multiple people at the same time have been known as furniture with a tabletop that is placed in shared spaces such as offices and lobbies (see, for example, Patent Document 1).

However, conventional furniture is basically specialized for use as a specific piece of furniture, such as a table, and is not intended for use for other purposes.

On the other hand, there are also known podium-shaped pieces of furniture that can be placed in shared spaces and allow seating at various heights (see, for example, Non-Patent Document 1), but this furniture is not one whose basic form can be altered to change its use. In other words, this type of furniture is excellent for creating a forum for open discussion or creating a space suitable for lectures or presentations by devising various ways to use it while maintaining its podium-shaped form, but it is not intended that the basic podium-shaped form will be altered as needed.

The sliding structures 2, 3 are configured to be able to take a table mode (P) in which they are retracted into the space S1 under the tabletop of the furniture main body 1, and an expanded mode (Q1), (Q2) in which the step floors 25, 26, 35, 36 of the sliding structures 2, 3 protrude out of the space S1 under the tabletop.

As shown in Figures 1, 2, 4, 5, 7, 8 and 10, this furniture with a tabletop T is made up of multiple sliding structures (upper sliding structure 2 and lower sliding structure 3) with different heights of step floors 25, 26, 35, 36 arranged in a telescopic manner, and in the deployment modes (Q1) and (Q2), the step floors 25, 26, 35, 36 of these sliding structures 2 and 3 and the tabletop 4 are deployed in a staircase-like manner with a predetermined drop g. In addition, this furniture with a tabletop T is entirely movable.

That is, this furniture with a top T is configured to be able to selectively adopt a table mode (P) as shown by phantom lines in Figures 1 to 3 and 8, a sofa mode (Q1) (first mode of the unfolded mode) as shown in Figures 4 to 6, and a stadium mode (Q2) (second mode of the unfolded mode) as shown in Figures 7 to 9. The table mode (P) of the furniture with a top T is also shown by phantom lines in Figure 8.

A detailed explanation will be given below, but in this explanation, the side from which the sliding structures 2 and 3 protrude and retract will be referred to as the "front", and the protruding action of the sliding structures 2 and 3 will be referred to as the "forward movement", and the retracting action as the "rear movement". In this embodiment, the upper sliding structure 2 and the lower sliding structure 3 are arranged in a telescopic manner under the furniture body 1.

As shown in Figs. 2 to 10, the furniture body 1 comprises a pair of left and right leg bases 11 arranged in parallel, a pair of left and right support columns 12 each erected at the base end (rear end) of the leg bases 11, a tabletop support frame 13 cantilevered forward from the upper ends of the support columns 12, and a tabletop 4 arranged on the tabletop support frame 13. The leg bases 11 are equipped with rolling elements 111 such as wheels that roll in the front-rear direction. The furniture body 1 is movable using the rolling elements 111. The left and right support columns 12 are each in the form of a rectangular pipe, and are rigidly connected to each other by a lower cross member 14 and an upper cross member 15. The upper cross member 15 is in the form of a channel that opens forward, and both ends are positioned near the side ends of the tabletop 4. The tabletop support frame 13 extends forward from the support column 12 in a cantilever manner, with a first support leg 131 at the front end and a second support leg 132 in the middle. Both of these support legs 131 and 132 hang down from each tabletop support frame 13 and have rolling elements 133 at their lower ends.

As shown in Figures 1, 2, 4, 5 and 7 to 10, the tabletop 4 comprises a first tabletop portion 41 having a use end 41a on the side (front side) where the sliding structures 2 and 3 appear and disappear, and a second tabletop portion 42 having a use end 42a on the opposite side, and is configured so that the position of the first tabletop portion 41 can be changed in the direction in which the sliding structures 2 and 3 appear and disappear (front-rear direction) relative to the second tabletop portion 42. In other words, the use end 42c of the second tabletop portion 42 overhangs, and a lower leg space S3 is always formed below it into which the user U can insert his/her legs. On the other hand, the first tabletop 41 can be selectively fixed to either the front fixed position (F) as shown in FIG. 1 and FIG. 2 set on the tabletop support frame 13 or the rear fixed position (R) as shown in FIG. 4, FIG. 5, and FIG. 7 to FIG. 10. In the above-mentioned unfolded modes (Q1) and (Q2), it is fixed to the rear fixed position (R), and in the table mode (P), it is fixed to the front fixed position (F). Under the first tabletop 41 fixed to the front fixed position (F), a lower leg space S2 is formed that is the same as the lower leg space S3 formed under the second tabletop 42. In other words, the first tabletop 41 is configured so that the lower leg space S2 can be formed under its use end 41c by changing its position in the table mode (P), and the second tabletop 42 is configured so that the lower leg space S3 is always formed under its use end 42c.

When the first tabletop 41 is fixed in the front fixed position (F), as shown in Figs. 1 and 2, a gap S4 for inserting wiring is formed between the opposite end 41b of the first tabletop 41 and the opposite end 42b of the second tabletop 42, and a wiring duct 43 is arranged below the gap S4. In addition, a shielding plate 44 such as a transparent acrylic plate is erected along the gap S4 to suppress mutual diffusion of droplets emitted by the facing users. This tabletop 4 is arranged at a height of 800mm to 1050mm from the floor surface F, and is suitable for use in a standing position or while sitting on a high-type chair. 45 is the rear panel and 46 is the front panel.

As shown in Figures 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 support frame 23 cantilevered forward from the upper end positions of the support columns 22, a front floor support frame 24 cantilevered forward from the middle position of the support columns 22, a rear stepped floor 25 provided on the rear floor support frame 23, and a front stepped floor 26 provided on the front half of the front floor support frame 24. The leg base 21 is provided with rolling elements 211 such as wheels that roll in the forward and backward directions. 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-shaped member that is open to the front, and both ends are located near the side edges of the tabletop 4.

As shown in Figures 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. A first support leg 241 is provided at the front end, and a second support leg 242 is provided in the middle. Each support leg 241, 242 hangs down from the front floor board support frame 24 and has a rolling body 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. 29 is a front curtain board, and 20 is a rear curtain board.

As shown in Figures 1, 2 and 4 to 10, the lower slide structure 3 is equipped with a pair of stepped floors 35, 36 having a height difference corresponding to the drop g described above. Specifically, the slide structure 3 is equipped with a pair of left and right leg bases 31 arranged in parallel, a pair of left and right pillars 32 each erected at the base end (rear end) of the leg bases 31, a rear floor support frame 33 cantilevered forward from the upper end position of the pillars 32, a front floor support frame 34 cantilevered forward from the middle position of the pillars 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 equipped with rolling elements 311 such as wheels that roll in the front-rear direction. The left and right pillars 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-shaped member that is open to the front, and both ends are located near the side edges of the top plate 4.

As shown in Figures 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 suspended 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. 39 is a front panel, and 30 is a rear panel.

The upper sliding structure 2 and the lower sliding structure 3 constructed as described above 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 body 1, as shown in Figures 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 forward and backward. 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 stop the lower sliding structure 3 from protruding any further. This stopper 212 is attached after the lower sliding structure 3 is assembled under the upper sliding structure 2.

As shown in Figures 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 body 1 and can slide forward and backward. A stopper 112 is provided at the front end of the leg base 11 of the furniture body 1 to abut against the support 22 of the upper sliding structure 2 and prevent 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 body 1.

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

As shown in Figures 1, 2, 4, 5, 7, 8 and 10, the lower step of each slide structure 2, 3, i.e., the step 26 in front of the upper slide structure 2 and the step 36 in front of the lower slide structure 3, has a sofa 7 with a thickness corresponding to the above-mentioned drop g. As shown in Figure 7, each step 26, 36 has at least one of an aisle area (A) and a seating area (C), and the sofa 7 is placed in the seating area (C). In more detail, in this embodiment, the step 36 in front of the lower slide structure 3 has seating areas (C) on both sides of the aisle area (A) set in the center, and the sofa 7 is placed in both seating areas (C). The entire area of the step 35 behind the lower slide structure 3 is designated as the aisle area (A). A seating area (C) is set 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 it, 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). Furthermore, 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).

Here, FIG. 1 is an overall perspective view of the furniture with a top T in table mode (P), FIG. 2 is a right side view, and FIG. 3 is a bottom view. FIG. 4 is an overall perspective view of the furniture with a top T in sofa mode (Q1), FIG. 5 is a right side view, and FIG. 6 is a bottom view. FIG. 7 is an overall perspective view of the furniture with a top T in 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 table mode (P) with imaginary lines. Also, in FIG. 3, FIG. 6, and FIG. 9, the used end 42a of the second top portion 42 is shown as the right side. FIG. 10 is an exploded perspective view of the furniture with a top T.

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

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 where a small number of people can communicate. Figure 11 shows an example of a refreshment lounge area RA created by placing furniture T with a tabletop set to sofa mode (Q1) in a corner of an office space OS.

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 stepped floors 25, 26, 35, 36 of each sliding structure 2, 3 will unfold in a staircase-like manner. This makes it possible to create a collaboration area CA where events such as open innovation seminars with a limited number of participants can be held.

Figure 12 shows an example in which furniture with a top T set to table mode (P) is placed in one corner of an office space OS to create a flexible work area FA, and furniture with a top T set to stadium mode (Q2) is placed next to it to create a collaboration area CA where seminars and other events can be held.

With furniture T with a tabletop configured in this way, its 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 T with a tabletop 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, 3 relative to the furniture body 1, eliminating the time and effort required for replacing dedicated furniture.

In addition, in this embodiment, multiple sliding structures 2, 3 with different heights of step floors 25, 26, 35, 36 are arranged in a telescopic manner, so that even though a vast tiered form can be realized in the unfolded state, 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.

Furthermore, since each of the sliding structures 2, 3 has a pair of step floors 25, 26, 35, 36 with 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 sliding structures 2, 3 to a minimum, and it is possible to prevent an increase in the number of parts and a complicated structure.

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 telescoped without removing the sofa 7, minimizing the effort required for changing modes.

Of course, the present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.

For example, in the above embodiment, the case where the deployment mode has two different mode configurations has been described, but the deployment mode may be only one of the sofa mode and the stadium mode.

The number of types of sliding structures is also not limited to two, and may be one or three or more. Increasing the number of types of sliding structures will also make it possible to further increase the number of deployment modes.

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 mentioned above, it is possible to realize a staircase shape that is easy to move around in while keeping the number of slide structures to a minimum, and it is possible to prevent an increase in the number of parts and a complicated structure.

In addition, in the illustrated example, each floor step has 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, the effect is that it is easier to optimize the design of the aisles.

The tabletop of the furniture body is not limited to having a first tabletop portion and a second tabletop portion, and may be, for example, a single piece. However, if the fixed position of the first tabletop portion can be changed as in the illustrated example, the advantage is that in the table mode, the lower leg space can be effectively created on both the front and rear sides of the tabletop, and in the unfolded mode, the first tabletop portion can be retracted so as not to get in the way.

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

In addition, side panels may be provided to hide the space below the tabletop or the step floor from the lateral space, 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.

The overall width of the furniture with a tabletop is of course not limited to the example shown in the figure, and can be modified in various ways. In addition, multiple pieces of furniture with a tabletop according to the present invention, each having a predetermined width, can be connected together in the width direction for use.

Various modifications are possible without departing from the spirit of the present invention.
