Description

[Technical field]

[0001] The present invention relates to furniture with a tabletop that is suitable for use in shared spaces such as offices and lobbies. [Background technology]

[0002] Conventionally, this type of furniture with a tabletop has been developed as comprising a furniture body having a tabletop, and two upper and lower sliding structures having a step floor lower than the tabletop and arranged so as to be able to move forward and backward in the space under the tabletop of the furniture body, with these sliding structures arranged in a telescopic manner (see, for example, Patent Document 1).

[0003] This furniture with a tabletop can take two modes: a recessed mode in which all of the sliding structures are recessed into the space under the tabletop of the furniture body, and an expanded mode in which the floor panels of all of the sliding structures protrude outside the space under the tabletop and are arranged in a staircase-like pattern, and it has gained popularity as furniture whose overall shape can be changed depending on how it is used.

[0004] However, in the conventional furniture, each sliding structure has two floor steps with a step, with the front floor step forming a seating area and the rear floor step forming an aisle area. Therefore, the structure of each sliding structure is relatively complicated, and the group of sliding structures is inevitably tall due to the step between the front and rear floor steps. Therefore, there is a problem that it is difficult to meet the demands for simplifying the structure or increasing the design freedom of the furniture tabletop height.

[0015] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0016] As shown in Figures 1 to 12, the furniture T with a top plate of this embodiment comprises a furniture main body 1 having a top plate 11, and a sliding structure (in this embodiment, an upper sliding structure 2 and a lower sliding structure 3) having floor boards 21, 31 at a position lower than the top plate 11 and arranged so as to be able to appear and disappear in the front and rear of the space S1 under the top plate of the furniture main body 1, and the multiple sliding structures 2, 3 with the floor boards 21, 31 at different heights are arranged in a telescopic manner. Note that in this specification, the "front-rear direction" means the direction in which the sliding structures 2, 3 appear and disappear, and may also be described as the "depth direction".

[0017] This furniture T with a tabletop is configured to be capable of taking an immersion mode (hereinafter referred to as "sofa mode P") in which a part of the sliding structures 2 is immersed in the space S1 under the tabletop of the furniture main body 1, and an expansion mode (hereinafter referred to as "stadium mode Q") in which the floor plates 21, 31 of all the sliding structures 2, 3 protrude out of the space S1 under the tabletop. In the sofa mode P in this embodiment, the upper sliding structure 2, which is a part of the sliding structures, is immersed in the space S1 under the tabletop, and the lower sliding structure 3 is immersed in the space S1 under the tabletop with a seat having a sofa exposed to the outside. In the immersion mode (sofa mode P) in this embodiment, both the sliding structures 2, 3 are stopped at the most retreated positions.

[0018] Each of the slide structures 2, 3 has a flush floor panel 21, 31, respectively, and the floor panel 31 of at least the lowest slide structure 3 has a seat area 31x on the leading edge side and an aisle area 31y on the trailing edge side.

[0019] That is, this furniture T with a top is configured to be capable of selectively adopting a sofa mode P as shown in Figs. 1 to 6 and a stadium mode (Q) as shown in Figs.

[0020] A specific description will be given below, in which the side from which the sliding structures 2 and 3 protrude and retract is defined as the "front", the protruding action of the sliding structures 2 and 3 is defined as the "forward movement", and the retracting action is defined as the "rear movement".

Similarly, in FIG. 13, the leg base 22, the support column 23, the floor support frame 24, and the auxiliary frame 28 of the upper slide structure 2 are shown in bold lines. Furthermore, in FIG. 13, the leg base 32, the support column 33, the floor support frame 34, and the auxiliary frame 39 of the lower slide structure 3 are also shown in bold lines. FIG. 14 is an explanatory diagram for explaining the function and effect of the tabletop-equipped furniture according to this embodiment, and is shown in a schematic cross-sectional side view. FIG. 14(a) shows a conventional tabletop-equipped furniture R, and FIG. 14(b) shows the tabletop-equipped furniture T of this embodiment.

[0024] In the furniture T with a tabletop of this embodiment shown in these drawings 1 to 14, the above-mentioned multiple sliding structures correspond to the lower sliding structure 3 and the upper sliding structure 2 having a floor board 21 at a position higher than the floor board 31 of the lower sliding structure. A seat area 31x and a passage area 31y are arranged adjacently in the front and rear on the floor board 31 of the lower sliding structure 3, and only the seat area 21x is arranged on the floor board 21 of the upper sliding structure 2. This will be described in detail below.

[0025] As shown in Fig. 6, Fig. 12 and Fig. 13, the furniture body 1 comprises a pair of left and right leg bases 12 arranged in parallel, a pair of left and right support columns 13 each erected at the base end (rear end) of the leg bases 12, a tabletop support frame 14 cantilevered forward from the upper end of the support columns 13, and a tabletop 11 arranged on the tabletop support frame 14. The leg bases 12 are plate-shaped and placed on the floor surface F, and extend in the front-rear direction. The left and right support columns 13 are each in the form of a rectangular pipe, and are rigidly connected to each other by reinforcing frames such as lower cross members and upper cross members (not shown). The tabletop is supported by being fastened to the tabletop support frame 14 and reinforcing frames (not shown) by screws or the like.

[0026] The furniture body 1 has a space S1 under the top plate 11 that can accommodate the upper sliding structure 2, and the leg bases 12, the support columns 13, the top plate support frame 14, and a reinforcing frame material (not shown) are arranged to ensure the space S1 under the top plate. The furniture body 1 is provided with side panels 15 that hang down from both the left and right edges of the top plate 11, a front panel 16 that hangs down from the front edge of the top plate 11, and a back panel 17 that hangs down from the vicinity of the rear edge of the top plate 11. The side panels 15, the front panel 16, and the back panel 17 are fastened to the top plate 11 and the reinforcing frame material that supports the top plate 11 by fasteners such as screws. The upper end surfaces of the side panels 15 may protrude above the top surface of the top plate 11 as shown in Figs. 1 and 7, or may be aligned at the same height as shown in Figs. 3 and 9.

[0027] 2, 6, 8, 9, 10, 12, and 13, an adjuster 18 that comes into contact with the floor surface F is provided at the front end of the side panels 15 arranged on the left and right sides of the furniture main body 1, and an auxiliary wheel 1c that comes into rolling contact with the floor panel 21 of the sliding structure 2 is provided near the lower end of the front panel 16, as shown in Figs. 1-4, 7-10, 12, and 13. As shown in Fig. 13, the auxiliary wheel 1c is attached to the lower end of an auxiliary frame 19 suspended from the top panel 11 or a reinforcing frame material, and is provided at a position where it can roll into contact with both left and right ends of the floor panel 21 and the center in the left and right direction.

[0028] The rear edge of the tabletop 11 is the use end 11a, and the back panel 17 is offset forward from the use end 11a of the tabletop 11 to form a lower leg space S2 below the tabletop 11. That is, the use end 11a side of the tabletop 11 overhangs, and the lower leg space S2 is always formed below where the user can insert their legs. The top surface of the tabletop 11 is preferably set at a height of about 700 mm to 1050 mm above the floor surface F, but in this embodiment, it is set at 1050 mm assuming use in a standing position or a sitting position on a high-type chair.

[0029] As shown in Figs. 2, 3, 6, 8 to 13, the upper slide structure 2 is provided with a flat floor plate 21, and a seat 27 having a sofa 271 is formed on the floor plate 21. Specifically, as shown in Fig. 13, the slide structure 2 is provided with a pair of left and right leg bases 22 arranged in parallel, a pair of left and right support columns 23 each erected at the base end (rear end) of the leg bases 22, a floor plate support frame 24 cantilevered forward from the upper end positions of the support columns 23, and a floor plate 21 supported on both the floor plate support frames 24. The leg base 22 is provided with running wheels 2a that roll in the front-rear direction. The left and right support columns 23 are each in the form of a rectangular pipe, and are rigidly connected to each other by reinforcing frame members such as lower cross members and upper cross members not shown. The floor plate 21 is supported by being fastened to the floor plate support frame 24 and reinforcing frame members not shown by screws or the like.

[0030] The upper slide structure 2 has a space below the floor plate 21 capable of accommodating the lower slide structure 3, and the leg bases 22, posts 23, floor plate support frame 24, and a reinforcing frame material (not shown) are arranged to ensure this space. The upper slide structure 2 is provided with side plates 25 that hang down from both the left and right edges of the floor plate 21, and a front plate 26 that hangs down from the front edge of the floor plate 21. The side plates 25 and the front plate 26 are fastened to the floor plate 21 and the reinforcing frame material that supports the floor plate 21 via fasteners such as screws.

[0031] Furthermore, running wheels 2a that roll on the floor surface F are axially attached to the leg bases 22 of the upper slide structure 2, and auxiliary wheels 2c that roll into contact with the floor plate 31 of the lower slide structure 3 are disposed near the lower end of the front plate 26 as shown in Figures 1 to 4, 7 to 10, 12 and 13. The auxiliary wheels 2c are axially attached to the lower end of the auxiliary frame 28 suspended from the floor plate 21 or the reinforcing frame material, and are provided in positions that allow them to roll into contact with both left and right ends and the left and right center of the floor plate 31.

[0032] As shown in Figs. 7 to 11, a seat 27 is provided on the upper sliding structure 2. That is, the floor board 21 of the sliding structure 2 has a small depth dimension in which only the seat area 21x is formed, and the seat 27 is formed by placing a sofa 271 on the seat area 21x. The depth dimension of the seat area 21 in this embodiment is set to, for example, about 450 mm. In this embodiment, the front end 271a of the sofa 271 protrudes slightly (about 50 mm) forward from the front edge 21a of the floor board 21. Therefore, when the sofa mode P is set, the front end 271a of the sofa 271 protrudes forward from the front end of the furniture main body 1 as shown in Figs. 2 and 3. As a result, the front end 271a of the sofa 271 can function as a lumbar support that supports the waist area of ​​a person sitting on the seat 37 of the lower sliding structure 3.

[0033] As shown in Figs. 1-5, 7-11, 13 and 14, the lower slide structure 3 has a flush floor plate 31, and a seat 37 having a sofa 371 and an aisle 38 are formed on the floor plate 21. Specifically, as shown in Figs. 6, 12 and 13, the slide structure 3 has a pair of left and right leg bases 32 arranged in parallel, a pair of left and right pillars 33 erected on the base ends (rear ends) of the leg bases 32, a floor plate support frame 34 extended forward from the upper ends of the pillars 33, and a floor plate 31 supported on both the floor plate support frames 34. The leg base 32 has running wheels 3a that roll in the front-rear direction. The left and right pillars 33 are each a rectangular pipe shape, and are rigidly connected to each other by reinforcing frame members such as lower cross members and upper cross members not shown. The floor board 21 is supported by being fastened to a floor board support frame 24 or a reinforcing frame material (not shown) using screws or the like.

[0034] The lower sliding structure 3 is provided with side plates 35 hanging down from both left and right edges of the floor plate 31, and a front plate 36 hanging down from the front edge of the floor plate 31. The side plates 35 and the front plate 36 are fastened to the floor plate 31 and a reinforcing frame material supporting the floor plate 31 by fasteners such as screws.

[0035] 6 and 12, a plurality of running wheels 3a that roll on the floor surface F are axially attached to the leg bases 32 of the lower sliding structure 3, and a plurality of running wheels 3b that roll on the floor surface F are also arranged at locations other than the leg bases 32. These running wheels 3b are also intended to support the load placed on the floor plate 31 on the floor surface F, and are arranged at both left and right ends of the floor plate 31 and at the center in the left and right direction.

[0036] The depth dimension of the lower slide structure 3 is set to be larger than the depth dimension of the upper slide structure 2. The lower slide structure 3 also has a flat floor plate 31 without any step, and is provided with a seat area 31x on the front edge side and a passage area 31y on the rear edge side. A sofa 371 is placed on the seat area 31x to form a seat 37, and the passage area 31y can be used as a passage 38. In this embodiment, the depth dimension of the seat area 31x is set to about 450 mm, and the depth dimension (passage width dimension) of the passage area 31y is set to about 550 mm. This passage width dimension is set as a dimension that can secure both a space for a seated person P seated on the seat 27 of the upper slide structure 2 to place his / her feet and a space required for others other than the seated person P to pass in front of him / her, which is significantly different from the conventional one.

[0037] The upper sliding structure 2 and the lower sliding structure 3 constructed as described above are combined in a telescopic manner and arranged so as to be capable of projecting and retracting into the space S1 under the top board of the furniture main body 1, as shown in Figures 7 to 9. A stopper (not shown) is provided between the furniture main body 1 and the upper sliding structure 2, which determines the most rearward and most forward positions of the sliding structure 2 relative to the furniture main body 1. A stopper mechanism (not shown) is provided between the upper sliding structure 2 and the lower sliding structure 3, which determines the most rearward and most forward positions of the lower sliding structure 3 relative to the upper sliding structure 2.

[0038] Therefore, in the sofa mode P (see Figs. 1 to 6) in which the sliding structure 2 is in the most rearward position relative to the furniture main body 1 and the sliding structure 3 is in the most rearward position relative to the sliding structure 2, the upper sliding structure 2 is recessed into the space S1 under the top board of the furniture main body 1, and the lower sliding structure 3 is recessed into the space S1 under the top board leaving the seat 37. When the lower sliding structure 3 is pulled forward from this sofa mode P, when this sliding structure 3 reaches the most forward position relative to the upper sliding structure 2, the sliding structure 2 also follows and starts to move forward. Then, when the upper sliding structure 2 reaches the most forward position, the forward movement of both sliding structures 2 and 3 is stopped by the furniture main body 1, and the stadium mode Q (see Figs. 7 to 12) is entered.

[0039] When the lower sliding structure 3 is pushed backward from this stadium mode Q, the sliding structure 2 follows and starts to move backward when the lower sliding structure 3 reaches its most rearward position relative to the sliding structure 2, and the rearward movement of all the sliding structures 2, 3 is stopped when the sliding structure 2 reaches its most rearward position relative to the furniture main body 1. In other words, this furniture T with a tabletop returns to its original sofa mode P. The notch 36a provided in the front panel 36 of the lower sliding structure 3 is for attaching a towing tool (not shown).

[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] Moreover, in the present furniture with a tabletop T, instead of providing each of the sliding structures 2, 3 with multiple stepped floors, flat floor panels 21, 31 are provided, and the seating areas 21x, 31x and the aisle area 31y are formed on the flat floor panels 21, 31, so that the structure of the sliding structures 2, 3 can be simplified compared to a structure in which stepped seating steps and stepped aisle steps are provided separately. In other words, when multiple stepped steps are provided on each sliding structure, step floor support frames of different heights are required, but in the sliding structures 2, 3 of the present application having flat floor panels 21, 31, it is sufficient to provide linear floor board support frames 24, 34, and the structure is simplified.

[0042] In addition, in the furniture with a tabletop T of the present application shown in Fig. 14(b), the seat area 31x and the passage area 31y are provided on the flush floor board 31 of the lowest sliding structure 3, so that the height dimension k of the passage 38 can be reduced. That is, in the conventional furniture with a tabletop R in which the steps for seats and the steps for passage are alternately provided in a staircase shape as shown in Fig. 14(a), even the lowest passage 138 has a relatively large height dimension j, so that it is desirable to provide handrails or auxiliary furniture for preventing falls on the sides of the furniture with a tabletop R, but in the furniture with a tabletop T of the present application, such consideration is not essential. Therefore, with such furniture with a tabletop T, it is possible to climb up and down onto the passage 38 from the side, and safety and usability are significantly improved.

[0043] Furthermore, in the conventional furniture R, the depth dimension of the step floor for the passage is set relatively small, so that the separation distance m between the front and rear seated persons u1 and u2 is relatively small. However, in the furniture T with a tabletop of the present application, the depth dimension of the passage 38 is set to, for example, about 550 mm. Therefore, this passage 38 can secure both a space for the seated person q2 to put his / her feet and a space for other people other than the seated person q2 to pass through. The depth dimension of the passage 38 of the furniture T with a tabletop can be easily changed by changing the relative forward / rearward movement dimension of the lower sliding structure 3 with respect to the upper sliding structure 2. Incidentally, in the embodiment of FIG. 14, for example, the separation distance m between the seated persons u1 and u2 of the conventional furniture R with a tabletop is set to about 219 mm, while the separation distance n between the seated persons q1 and q2 of the furniture T with a tabletop of the present application is set to about 429 mm.

[0044] Furthermore, according to the furniture T with a tabletop of this embodiment, the passage 38 of the lower sliding structure 3 is lower than the seat surface of the seat 37, so the position of the seat 27 of the upper sliding structure 2 can also be set lower than the position of the seat 127 in the conventional furniture R. This makes it possible to secure a large surplus space S3 formed between the upper sliding structure 2 and the tabletop 11 of the furniture main body 1. This results in a wider setting range for the height dimension h of the tabletop 11 of the furniture main body 1, which has the effect of increasing the degree of freedom in design. Furthermore, when the height dimension h of the tabletop 11 is close to the conventional value, this surplus space S3 can also be used as a storage space.

[0045] Of course, the present invention is not limited to the above-described embodiment, and includes the following aspects.

[0046] In other words, in the invention of claim 1, the sliding structure is not limited to two, one above and one below, as in the above embodiment, but three or more sliding structures may be provided when there are circumstances in which the height of the tabletop of the furniture body can be arranged at a high position, for example, when the architectural floor surface on the use end side of the tabletop is higher than the architectural floor surface on the opposite use end side. Even when two sliding structures are used, for example, a configuration in which a seat area and an aisle area are provided on the floor panels of both the upper and lower sliding structures can be considered. When adopting this configuration, it is desirable to provide a seat area on the opposite end of the top panel of the furniture body to the usable end, and to detachably mount a seat element such as a sofa on the seat area.

[0047] Also, the front-to-rear width dimension of the passage area is preferably set to a value that ensures both a space for the person sitting on the sofa above to put their feet and a space for other people to pass in front of the person sitting on the sofa, but it can also be set to another dimension. That is, according to the present invention, since the seat area and the passage area are formed on a single, flush floor board, the dimensional ratio between the seat area and the passage area can be set and changed relatively freely by appropriately selecting the sliding mode of the sliding structure.

[0048] Furthermore, in the above embodiment, the immersion mode (sofa mode) in which the upper sliding structure is immersed in the space under the tabletop and the lower sliding structure is retreated into the space under the tabletop leaving the seating portion outside, and the deployment mode (stadium mode) in which the floor panels of all the sliding structures protrude outside the space under the tabletop have been described, but an immersion mode (table mode) in which all the sliding structures are almost completely immersed in the space under the tabletop may be added. In this case, various modes are possible, such as a combination of the sofa mode and the stadium mode, a combination of the table mode and the stadium mode, or a combination of the table mode, the sofa mode and the stadium mode.

[0049] In addition, the height h of the tabletop is not limited to 700mm 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 to less than 700mm, 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.

[0050] In the embodiment shown in Figs. 1 to 14, the height h of the tabletop 11 of the furniture main body 1 is set to 1050 mm, but it may be, for example, as shown in Fig. 15 (another embodiment). That is, the furniture with a tabletop 1 of the other embodiment shown in Fig. 15 is made possible by minimizing the spare space S3 of the above-mentioned embodiment, and the height h of the tabletop 11 of the furniture main body 1 is set to about 700 mm, which is the height of a normal desk tabletop. The configuration of the other embodiment shown in Fig. 15 is basically the same as that of the above-mentioned embodiment, and the same or corresponding parts are denoted by the same reference numerals and description thereof will be omitted.

[0051] FIG. 15 is a side view showing a tabletop-equipped furniture T of another embodiment, and running wheels and the like are omitted. The dimensional relationship in this embodiment is specifically described as follows. The depth dimension v of the tabletop 11 in the tabletop-equipped furniture 1 of FIG. 15 is set to about 1000 mm, the maximum protruding dimension w of the upper sliding structure 2 relative to the furniture body 1 is set to about 450 mm, and the maximum protruding dimension x of the lower sliding structure 3 relative to the upper sliding structure 2 is set to about 1000 mm. The above settings are in accordance with the above-mentioned embodiment. On the other hand, the height k of the passage 38 of the sliding structure 3 from the floor surface F is set to about 280 mm, which is lower than that of the embodiment. The seat heights y and z of the seats 27 and 37 of the sliding structures 2 and 3 are suppressed to about 400 mm.

[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 pieces 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 the above embodiment, the furniture body does not slide relative to the floor surface, but the furniture body may also be slid back and forth. However, by making the furniture body a non-sliding type, and by making each sliding structure have a flush floor board as in the above embodiment, and further by limiting the selection modes to sofa mode and stadium mode, it is possible to particularly promote the simplification of the structure and the compactness of the entire product.

[0054] In addition, various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
