Description

[Technical field]

[0001] The present invention relates to a combination furniture which combines a plurality of sofas or a plurality of sofas with other furniture. [Background technology]

[0002] A sofa is a piece of furniture similar to a chair, and often has a backrest at the back and armrests on both sides. The seat and backrest are soft and comfortable, and can accommodate one or several people to sit and relax. Sofas are found in living rooms, guest rooms, and reception rooms in homes, as well as in offices and hotel rooms. In this case, when a plurality of sofas are installed and used, or when a sofa is used in combination with other furniture, various proposals have been made from the viewpoints of usability, space efficiency, design, and the like.

[0003] For example, Patent Document 1 (Japanese Utility Model Publication No. 55-139759) discloses a sofa structure comprising armrest members, a backrest member and a seat cushion, wherein the armrest members have the same horizontal length of the armrest face and the same back thickness of the backrest member, and the seat cushion member has a square shape with one side being the length obtained by subtracting the back thickness of the backrest member from the length of the armrest face of the armrest member, and wherein the sofa structure comprises a sofa comprising a plurality of such seat cushion members arranged in parallel, another sofa from which one or both armrest members of the sofa are missing, or any combination of such other sofas. However, the sofa structure in Patent Document 1 is a combination of multiple sofas, each with a square-shaped seat cushion member, and as shown in Figure 2, it can only have an angular shape such as an L-shape or a U-shape, which causes a problem of poor design. Furthermore, with the sofa structure of Patent Document 1, when multiple sofas are arranged, empty spaces are generated which are surrounded by the sofas, and when not in use or when displayed in a store, require a larger installation area than the sofa area, resulting in poor space efficiency.

[0004] Incidentally, Patent Document 2 (Japanese Utility Model Publication No. 59-41148) discloses a unit furniture comprising a number of chairs supported at a predetermined height above the floor by legs attached to the four corners of the underside, a storage section whose periphery is surrounded by the front faces of the chairs, a yagura kotatsu (heated table with a raised floor) installed in this storage section, and a shielding body attached to the supporting legs of the yagura kotatsu, connected to the peripheral lower end of the storage section, and closing the gap between the undersides of the chairs and the floor. In the unit furniture of Patent Document 2, when the yagura kotatsu is combined with multiple chairs, there is no empty space between the yagura kotatsu and the chairs, and when not in use, it does not require an area larger than the yagura kotatsu and chairs, making it space-efficient; however, since the yagura kotatsu is located in the center, it can only be used as furniture that includes the yagura kotatsu.

As shown in the figure, the combination furniture 1 is composed of a stool 20 placed in the center and a group of sofas 10 placed around it. The group of sofas 10 consists of a first sofa 11, a second sofa 12, a third sofa 13 and a fourth sofa 14, and the stool 20 consists of small stools 21 and 22.

[0023] [sofa] As shown in FIG. 2, the first sofa 11 has a seat portion 11a, a backrest portion 11c, a right armrest portion 11c1, and a left armrest portion 11c2, and is symmetrical in shape. It is made of surface materials such as genuine leather (natural leather), synthetic leather, and fabric, cushioning material, a frame, etc., and is capable of seating 1 to 5 adults. The seat 11a has a seat surface 11Z on the upper side, a central front surface 11M on the front side, and a first side surface 11S1 and a second side surface 11S2 on the side sides, the central front surface 11M is curved to form the circumferential surface of a quadrant cylinder, and the first side surface 11S1 and the second side surface 11S2 are flat surfaces that are perpendicular to the circumferential surface of the central front surface 11M. In other words, the first side surface 11S1 and the second side surface 11S2 are flat surfaces that are normal to the circumferential surface of the quadrant cylinder formed by the central front surface 11M. Front legs 11k1, 11k2 are attached to the front side of a bottom surface 11B of the seat portion 11a, and rear legs 11k3, 11k4, 11k5 are attached to the rear side. The front legs 11k1, 11k2 and the rear legs 11k3, 11k4, 11k5 have the same cylindrical shape. The backrest 11b is curved horizontally and outwardly in an arc shape, inclined so as to widen in the vertical direction, and is attached to the rear side of the seat 11a integrally with the right armrest 11c1 and the left armrest 11c2. In this case, the outer surface of the right armrest 11c1 is arranged to extend along the first side surface 11S1, and the outer surface of the left armrest 11c2 is arranged to extend along the second side surface 11S2. As shown in FIG. 1, the second sofa 12, the third sofa 13 and the fourth sofa 14 respectively have seat portions 12a, 13a and 14a, backrest portions 12b, 13b and 14b, right armrest portions 12c1, 13c1 and 14c1, and left armrest portions 12c2, 13c2 and 14c2, and are of the same size, shape and material as the first sofa 11. In addition, all or part of the first sofa 11, the second sofa 12, the third sofa 13, and the fourth sofa 14 may be made to have a similar shape to the other sofas, for example, a similar shape with the right armrest, the left armrest, and the backrest slightly modified in shape.

[0024] [stool] As shown in Figs. 4 and 5, the stool 20 is cylindrical and made up of two small stools 21 and 22, and has no backrest and functions primarily as a chair for one person. The small stool 21, like the first sofa 11, is made of a surface material such as genuine leather (natural leather), synthetic leather, fabric, etc., a cushioning material, a frame, etc., has a seat surface 21Z on the upper side, and is semi-cylindrical in shape with an outer periphery consisting of a curved peripheral surface 21W on the front side and a flat peripheral surface 21H on the back side. The seat surface 21Z is a curved surface that bulges slightly upward, the curved peripheral surface 21W is a surface that is curved in a semicircular shape, and the flat peripheral surface 21H is a flat surface. The small stool 21 has a bottom surface 21B to which are attached legs 21k1, 21k2, and 21k3, each of which has the same cylindrical shape. The small stool 22, like the small stool 21, is made of a surface material such as genuine leather (natural leather), synthetic leather, cloth, etc., a cushioning material, a frame, etc., has a seat surface 22Z on the upper side, and is semi-cylindrical in shape with an outer periphery consisting of a curved peripheral surface 22W on the back side and a flat peripheral surface 22H on the front side. The seating surface 22Z is ​​a curved surface that bulges slightly upward like the seating surface 21Z, the curved peripheral surface 22W is a semicircularly curved surface like the curved peripheral surface 21W, and the flat peripheral surface 22H is a flat surface like the flat peripheral surface 21H. The small stool 22 has a bottom surface 22B to which are attached legs 22k1, 22k2, and 22k3, each of which has the same cylindrical shape as the bottom surface 21B. The small stool 21 and the small stool 22 have the same size, shape and material, and the overlapping surface 21L and the overlapping surface 22L are overlapped to form the stool 20 whose outer peripheral surface is cylindrical. In this case, the corners at the boundary between the flat peripheral surface 21H and the curved peripheral surface 21W of the small stool 21 are rounded, and the corners at the boundary between the flat peripheral surface 22H and the curved peripheral surface 22W of the small stool 22 are also rounded, so that the corners of the small stools 21 and 22 of the stool 20 are slightly concave. However, stools in which part of the cylindrical surface is concave in this manner are also included in the cylindrical stools of the present invention. In addition, the height from the underside of the leg (21k1, etc.) of the stool 20 to the seat (seat 21Z, seat 22Z) is the same as the height from the underside of the leg (11k1, etc.) of the first sofa 11, etc. to the seat (11Z, etc.). Furthermore, the small stool 21 and the small stool 22 can be separated and used as individual stools.

[0025] [Arrangement of sofa group 10 and stool group 20] As shown in FIG. 1, a combination furniture 1 is formed by placing a stool 20 in the center and arranging a first sofa 11, a second sofa 12, a third sofa 13, and a fourth sofa 14 of a sofa group 10 in the circumferential direction around the stool 20 in that order. In this case, the central front surface 11M of the seat 11a of the first sofa 11 forms the circumferential surface of a quarter cylinder, and since the radius of this quarter cylinder is the same as the radius of the cylinder formed by the stool 20, the circumferential length of the central front surface 11M is one-fourth of the circumferential length of the cylinder formed by the stool 20, and the central front surface 11M overlaps with a part of the outer peripheral surface of the stool 20 (one-fourth of the circumference) without any gaps. The central front surfaces of the seats 12a of the second sofa 12, 13a of the third sofa 13, and 14a of the fourth sofa 14 also form the circumferential surface of a quarter cylinder of the same size as that of the first sofa 11, and therefore overlap without any gaps with a part of the outer circumferential surface of the stool 20 (a quarter of the circumference). In addition, in the seat portion 11a of the first sofa 11, the first side surface 11S1 and the second side surface 11S2 are flat surfaces normal to the circumferential surface of the quarter cylinder formed by the central front surface 11M, and a right armrest portion 11c1 is provided along the first side surface 11S1, and a left armrest portion 11c2 is provided along the second side surface 11S2. In the other seats 12a of the second sofa 12, 13a of the third sofa 13, and 14a of the fourth sofa 14, the first and second sides of each seat are flat surfaces normal to the circumferential surface of the quarter cylinder formed by the central front, and right armrests 12c1, 13c1, 14c1 are provided along the first side, and left armrests 12c2, 13c2, 14c2 are provided along the second side. As a result, as shown in Figure 1, the group of sofas 10 can be arranged around the stool 20 so that each central front overlaps with a portion of the outer peripheral surface of the stool 20 without any gaps, the adjacent first and second side surfaces of each sofa in the group of sofas 10 overlap without any gaps, and the adjacent right and left armrests of each sofa in the group of sofas 10 overlap without any gaps, so that no empty space is created between the group of sofas 10 and the stool 20, and no empty space is created between adjacent sofas in the group of sofas 10.

[0026] Next, the height from the underside of each leg (11k1, etc.) in the sofa group 10 (first sofa 11, second sofa 12, third sofa 13, fourth sofa 14) to the seat (11Z, etc.) is the same as the height from the underside of the leg (21k1, etc.) of the stool 20 to the seat (seat 21Z, seat 22Z), and when the sofa group 10 and the stool 20 are placed on the same flat installation surface, no step is created between the seat (11Z, etc.) of each sofa in the sofa group 10 and the seat (seat 21Z, seat 22Z) of the stool 20, and each seat forms a flat surface. As a result, when the group of sofas 10 are arranged tightly around the stool 20 as shown in Figure 1, the stool 20 becomes the center of the flower, and the first sofa 11, the second sofa 12, the third sofa 13, and the fourth sofa 14 represent the petals, forming a flower shape as a whole and presenting an appearance with excellent design.

[0027] FIG. 6 is a plan view of a combination furniture set in which a group of sofas consisting of a first sofa 11, a second sofa 12, a third sofa 13, and a fourth sofa 14 are arranged around a stool 20 so that the center front of each sofa is a certain distance away from the outer peripheral surface of the stool 20. In the figure, 1' denotes the combination furniture set, and 10' denotes the group of sofas. As shown in FIG. 6, in the combination furniture 1', the sofa group 10' is composed of the same sofas as the sofa group 10, and each sofa of the sofa group 10 (the first sofa 11, the second sofa 12, the third sofa 13, and the fourth sofa 14) is arranged around the stool 20 with the center front of each sofa being a certain distance d away from the outer peripheral surface of the stool 20. In this way, by separating the central front of each sofa in the sofa group 10' by a certain distance d from the outer peripheral surface of the stool 20, a certain space is formed between each sofa and stool 20 and between adjacent sofas, allowing adults to sit on each sofa and stool 20 and to move between each sofa and stool 20 and between adjacent sofas. In this case, since the height of the seat surface (11Z, etc.) of each sofa in sofa group 10' is the same as the seat surface (seat surface 21Z, seat surface 22Z) of stool 20, the eye height of the person sitting on stool 20 and the person sitting on the sofa facing it, or the people sitting on adjacent sofas, are all at the same height and can face each other and chat. Furthermore, the stool 20 forms the center of the flower, with the first sofa 11, the second sofa 12, the third sofa 13, and the fourth sofa 14 representing the petals, maintaining the overall shape of a flower, making this an excellent arrangement from a design perspective.

[0028] As described above, the assembled furniture 1 is composed of the stool 20 arranged in the center and the sofa group 10 (first sofa 11, second sofa 12, third sofa 13, fourth sofa 14) arranged around the stool 20, the stool 20 has a cylindrical outer peripheral surface, each sofa of the sofa group 10 has a central front surface that overlaps with a part of the outer peripheral surface of the stool 20 (a quarter of the circumference), each of the sofas has a backrest that is curved horizontally and outwardly in an arc shape, and when the sofas are arranged around the stool 20, Each of the above sofas overlaps with the outer peripheral surface of the stool 20 without any gaps, leaving no empty space between the outer peripheral surface of the stool 20 and each of the above sofas, and adjacent sofas overlap with each other without any gaps, leaving no empty space between adjacent sofas. This eliminates any empty space in the installation space for the sofa group 10 (first sofa 11, second sofa 12, third sofa 13, fourth sofa 14) and stool 20 when they are not in use or are on display, etc., thereby improving the efficiency of the installation space.

Like the seat 11a and backrest 11b of the first sofa 11, the seat 31a and backrest 31b are made of a surface material such as genuine leather (natural leather), synthetic leather, or fabric, a cushion material, a frame, and the like. As shown in FIG. 7, the second main sofa 32, the third main sofa 33, and the fourth main sofa 34 each have a seat portion 32a, 33a, 34a and a backrest portion 32b, 33b, 34b, and are of the same size, shape, and material as the first main sofa 31.

[0031] As shown in Figs. 9(a) to (d), the first auxiliary sofa 35 has a seat portion 35a and a backrest portion 35b, similar to the first main sofa 31, and has no armrests, so that one or two adults can sit on it. The seat portion 35a has a seat surface 35Z on the upper side and a first side surface 35S1 and a second side surface 35S2 on the side sides. Unlike the first main sofa 31, there is no central front, and the seat surface 35Z is in the shape of a quarter circle. The first side surface 35S1 and the second side surface 35S2 are flat surfaces, and the first side surface 35S1 and the second side surface 35S2 are perpendicular to each other. Legs 35k1, 35k2, 35k3, and 35k4 are attached to a bottom surface 35B of the seat 35a, and these legs have the same cylindrical shape. The backrest portion 35b, like the backrest portion 31b of the first main sofa 31, is curved in an arc horizontally and outwardly and inclined so as to widen in the vertical direction, and its outer surface (back surface) forms part of the circumferential surface of a truncated cone and is attached to the back side of the seat portion 35a. In this case, there is no step at the boundary between the first side 35S1 and second side 35S2 of the seat portion 35a and the side of the backrest portion 35b, and the first side 35S1 and the left side of the backrest portion 35b form the same flat surface, and the second side 35S2 and the right side of the backrest portion 35b form the same flat surface. An inner circular arc 35L1 is formed at the boundary between the seat surface 35Z and the backrest portion 35b, and an outer circular arc 35L2 is formed at the boundary between the upper surface of the backrest portion 35b and the rear surface. Like the seat 31a and backrest 31b of the first main sofa 31, the seat 35a and backrest 35b are made of a surface material such as genuine leather (natural leather), synthetic leather, or fabric, a cushion material, a frame, etc. As shown in FIG. 7, the second auxiliary sofa 36, ​​the third auxiliary sofa 37, and the fourth auxiliary sofa 38 each have seat portions 36a, 37a, 38a and backrest portions 36b, 37b, 38b, and are of the same size, shape, and material as the first auxiliary sofa 35.

[0032] Here, in the main sofa, the height from the bottom of the legs (31k1, etc.) of the first main sofa 31 to the seat 31Z, the height from the bottom of the legs of the second main sofa 32 to the seat, the height from the bottom of the legs of the third main sofa 33 to the seat, and the height from the bottom of the legs of the fourth main sofa 34 to the seat are all the same, and the height from the bottom of the legs (31k1, etc.) of the first main sofa 31 to the top of the backrest 31b, the height from the bottom of the legs of the second main sofa 32 to the top of the backrest 32b, the height from the bottom of the legs of the third main sofa 33 to the top of the backrest 33b, and the height from the bottom of the legs of the fourth main sofa 34 to the top of the backrest 34b are all the same. In addition, in the auxiliary sofas, the height from the underside of the legs (35k1, etc.) of the first auxiliary sofa 35 to the seat 35Z, the height from the underside of the legs of the second auxiliary sofa 36 to the seat, the height from the underside of the legs of the third auxiliary sofa 37 to the seat, and the height from the underside of the legs of the fourth auxiliary sofa 38 to the seat are all the same, and the height from the underside of the legs (35k1, etc.) of the first auxiliary sofa 35 to the upper surface of the backrest 35b, the height from the underside of the legs of the second auxiliary sofa 36 to the upper surface of the backrest 36b, the height from the underside of the legs of the third auxiliary sofa to the upper surface of the backrest 37b, and the height from the underside of the legs of the fourth auxiliary sofa 38 to the upper surface of the backrest 38b are all the same. The height from the underside of the legs of each of the main sofas to the seat is the same as the height from the underside of the legs of each of the auxiliary sofas to the seat, and the height from the underside of the legs of each of the main sofas to the upper surface of the backrest is also the same as the height from the underside of the legs of each of the auxiliary sofas to the upper surface of the backrest. In addition, the horizontal length of the first side and the second side of each main sofa is the same as the horizontal length of the first side and the second side of each auxiliary sofa. Furthermore, the horizontal length of each of the main sofas added to the first side surface of the left side of the backrest, the horizontal length of each of the main sofas added to the second side surface of the right side of the backrest, and the horizontal length of each of the auxiliary sofas added to the first side surface of the left side of the backrest, and the horizontal length of each of the auxiliary sofas added to the second side surface of the left side of the backrest are all the same.

[0033] [stool] As shown in FIGS. 10(a) to (g), the stool 40 is made up of a base portion 41 and a seat portion 42, and like the stool 20, functions primarily as a chair for one person. Like the first main sofa 31, the base 41 is made of a surface material such as genuine leather (natural leather), synthetic leather, or fabric, cushioning material, a frame, etc., and has a slightly flattened rectangular shape with rounded corners, consisting of a top surface, outer peripheral surface and bottom surface 41B. The upper surface of base portion 41 is a square with rounded corners, and the outer peripheral surface of base portion 41 consists of a first peripheral surface 41S1, a second peripheral surface 41S2, a third peripheral surface 41S3, and a fourth peripheral surface 41S4, each of which has the same shape and size. On a bottom surface 41B of the base portion 41, identical cylindrical leg portions 41k1, 41k2, 41k3, and 41k4 are attached. The seat portion 42 is configured by laminating a cushion portion 42a and a plate portion 42b, and has a flat rectangular parallelepiped shape with rounded corners. The cushion portion 42a is made of a cushioning material, and its upper surface serves as a seating surface 42aZ, which is a square with rounded corners. The board portion 42b is made of a hard material such as wood or plastic, and its underside serves as a table surface. This table surface is a square with rounded corners and has the same size as the seat surface 42aZ. In addition, the height from the underside of the legs (11k1, etc.) of the stool 40 (base portion 41) to the seat surface 42aZ of the seat portion 42a is the same as the height from the underside of the legs (31k1, etc.) of the first main sofa 31, etc. to the seat surface (31Z, etc.).

[0034] Figure 11(a) is an enlarged front view of stool 40 in a state in which seat 42 is placed on the upper surface of base 41, with cushion portion 42a on the upper side and plate portion 42b on the lower side, and Figure 11(b) is an enlarged front view of stool 40 in a state in which seat 42 is placed on the upper surface of base 41, with plate portion 42b on the upper side and cushion portion 42a on the lower side; in the figure, plate portion 42 is shown in gray. As shown in FIG. 11(a), when seat 42 is placed on the top surface of base 41 with cushion portion 42a facing up, the top surface of stool 40 becomes seat 42a, on which a person can sit, and stool 40 functions as a traditional stool. Also, as shown in FIG. 10(b), when the seat 42 is placed on the upper surface of the base 41 with the board portion 42b facing up, the upper surface of the stool 40 becomes the table surface of the board portion 42b, and the stool 40 functions as a table.

[0035] [Arrangement of sofas 30 and stools 40] As shown in FIG. 7, a combination furniture 2 is formed by placing a stool 40 in the center and arranging the first main sofa 31, the first auxiliary sofa 35, the second main sofa 32, the second auxiliary sofa 36, ​​the third main sofa 33, the third auxiliary sofa 37, the fourth main sofa 34, and the fourth auxiliary sofa 38 of the sofa group 30 in the circumferential direction around the stool 40 in that order. Specifically, with regard to the main sofa, the central front surface 31M of the first main sofa 31 overlaps with the first peripheral surface 41S1 of the base portion 41 of the stool 40, but since the central front surface 31M and the first peripheral surface 41S1 are both flat surfaces and have the same horizontal (circumferential) length, they overlap without any gaps. The central front surfaces of the other second main sofa 32, third main sofa 33, and fourth main sofa 34 are also flat and have the same horizontal (circumferential) length as each peripheral surface of the base 41 of the stool 40, so that each central front surface overlaps without any gaps with the second peripheral surface 41S2, the third peripheral surface 41S3, and the fourth peripheral surface 42S4.

[0036] Next, with regard to the auxiliary sofas, the first auxiliary sofa 35 is positioned between the first main sofa 31 and the second main sofa 32, the second auxiliary sofa 36 is positioned between the second main sofa 32 and the third main sofa 33, the third auxiliary sofa 37 is positioned between the third main sofa 33 and the fourth main sofa 34, and the fourth auxiliary sofa 38 is positioned between the fourth main sofa 34 and the first main sofa 31. With regard to the first auxiliary sofa 35, the first side surface 35S1 overlaps with the second side surface 31S2 of the first main sofa 31, and the second side surface 35S2 overlaps with the first side surface of the second main sofa 32, but since each overlapping surface is flat and the horizontal lengths of the second side surface 31S2 of the first main sofa 31, the first side surface 35S1 and the second side surface 35S2 of the first auxiliary sofa 35, and the first side surface of the second main sofa 32 are the same, the sides of each sofa overlap without any gaps. In addition, in the first main sofa 31, the second side surface 31S2 and the right side surface of the backrest portion 31b are the same flat surface, in the first auxiliary sofa 35, the first side surface 35S1 and the left side surface of the backrest portion 35b are the same flat surface, the second side surface 35S2 and the right side surface of the backrest portion 35b are the same flat surface, and in the second main sofa 32, the first side surface and the left side surface of the backrest portion 32b are the same flat surface, and the horizontal length of the right side surface of the backrest portion 31b of the first main sofa 31, the horizontal lengths of the left side surface and right side of the backrest portion 35b of the first auxiliary sofa 35, and the horizontal length of the left side surface of the backrest portion 32b of the second main sofa 32 are all the same. As a result, the right side of the backrest portion 31b of the first main sofa 31 and the left side of the backrest portion 35b of the first auxiliary sofa 35 overlap without any gaps, and the right side of the backrest portion 35b of the first auxiliary sofa 35 and the left side of the backrest portion 32b of the second main sofa 32 also overlap without any gaps.

[0037] Similarly, with regard to the second auxiliary sofa 36, ​​the first side overlaps without any gaps with the second side of the second main sofa 32, the second side overlaps without any gaps with the first side of the third main sofa 32, the left side of the backrest portion 36b overlaps without any gaps with the right side of the backrest portion 32b of the second main sofa 32, and the right side of the backrest portion 36b overlaps without any gaps with the left side of the backrest portion 33b of the third main sofa 33. With regard to the third auxiliary sofa 37, the first side surface overlaps with the second side surface of the third main sofa 33 without any gaps, the second side surface overlaps with the first side surface of the fourth main sofa 34 without any gaps, the left side surface of the backrest portion 37b overlaps with the right side surface of the backrest portion 33b of the third main sofa 33 without any gaps, and the right side surface of the backrest portion 37b overlaps with the left side surface of the backrest portion 34b of the fourth main sofa 34 without any gaps. With regard to the fourth auxiliary sofa 38, the first side surface overlaps with the second side surface of the fourth main sofa 34 without any gaps, the second side surface overlaps with the first side surface of the first main sofa 31 without any gaps, the left side surface of the backrest portion 38b overlaps with the right side surface of the backrest portion 34b of the fourth main sofa 34 without any gaps, and the right side surface of the backrest portion 38b overlaps with the left side surface of the backrest portion 31b of the first main sofa 31 without any gaps. As a result, as shown in Figure 7, the sofa group 30 can be arranged around the stool 40 so that the central front faces of the main sofas overlap with the peripheral surfaces of the base 41 of the stool 40 without any gaps, and the side faces of each auxiliary sofa overlap with the side faces of the adjacent main sofas without any gaps, so that no empty space is created between the sofa group 30 and the stool 40, and no empty space is created between adjacent main sofas and auxiliary sofas in the sofa group 30.

[0038] Here, in the first main sofa 31, an inner circular arc 31L1 is formed at the boundary between the seat surface 31Z and the backrest portion 31b, and in the first auxiliary sofa 35, an inner circular arc 35L1 is formed at the boundary between the seat surface 35Z and the backrest portion 35b, but the radius of the inner circular arc 31L1 of the first main sofa 31 and the inner circular arc 35L1 of the first auxiliary sofa 35 are the same. In addition, in the other second main sofa 32, third main sofa 33, and fourth main sofa 34, an inner arc identical to the inner arc 31L1 is formed at the boundary between the seat and the backrest, and in the other second auxiliary sofa 36, ​​third auxiliary sofa 37, and fourth auxiliary sofa 38, an inner arc identical to the inner arc 35L1 is formed at the boundary between the seat and the backrest. And since the height from the bottom surface (placement surface) of the legs of each main sofa and each auxiliary sofa to the seat surface is the same, the height of the inner arc of each main sofa and the inner arc of each auxiliary sofa are also the same. As a result, the inner arcs of the main sofas and the inner arcs of the auxiliary sofas are connected without any misalignment in the front, back, up or down directions, forming an inner circle 30L1 as shown in FIG. Next, in the first main sofa 31, an outer circular arc 31L2 is formed at the boundary between the upper surface and the back surface of the backrest portion 31b, and in the first auxiliary sofa 35, an outer circular arc 35L2 is formed at the boundary between the upper surface and the back surface of the backrest portion 35b, but the radius of 31L2 of the first main sofa 31 and the outer circular arc 35L2 of the first auxiliary sofa 35 are the same. In addition, in the other second main sofa 32, third main sofa 33, and fourth main sofa 34, an outer arc identical to the outer arc 31L2 is formed at the boundary between the upper surface of the backrest and the back surface, and in the other second auxiliary sofa 36, ​​third auxiliary sofa 37, and fourth auxiliary sofa 38, an inner arc identical to the outer arc 35L2 is formed at the boundary between the upper surface of the backrest and the back surface. Furthermore, since the height from the bottom surface (placement surface) of the legs to the top surface of the backrest of each main sofa and each auxiliary sofa is the same, the heights of the inner arcs of each main sofa and the outer arcs of each auxiliary sofa are also the same. As a result, the outer arcs of the main sofas and the outer arcs of the auxiliary sofas are connected without any misalignment in the front, back, up or down directions, forming an outer circle 30L2 as shown in FIG.

[0039] Furthermore, since the height from the underside (placement surface) of the legs of the stool 40 to the seat 42aZ is the same as the height from the legs to the seats of each main sofa and each auxiliary sofa, the boundary line between the seats of each main sofa and the seat of the stool 40, and the boundary line between the seats of each main sofa and the seat of each auxiliary sofa are on the same plane as the inner circle 30L1. Therefore, the sofa group 30 (each main sofa and each auxiliary sofa) and the stool 40 form a square formed by the stool 40 at the center of the circular plate formed by the inner circle 30L1, the inner circle 30L1 and this square are separated by lines extended from each side of the square, the outer circle 30L2 is formed outside the inner circle 30L1, and the inner circle 30L1 and the outer circle 30L2 form a convex ring. Overall, it is reminiscent of an old coin with a convex ring portion on the outer periphery of a circular plate with a square hole in the center, and convex lettering between each side of the square and the ring portion. The arrangement of the sofa group 30 and the stool 40 is also excellent in terms of design. In addition, the circumferential surfaces of the truncated cone formed by the outer surfaces (backs) of the backrests of each main sofa and each auxiliary sofa are connected without coming off to form a truncated cone, resulting in a harmonious appearance in terms of design.

[0040] FIG. 12 is a plan view of a combination furniture in which a group of sofas consisting of the main sofa and auxiliary sofas are arranged around a stool 40 so that the center front of the main sofa is a certain distance away from the outer peripheral surface of the stool 40. In the figure, 2' is the combination furniture and 30' is the group of sofas. As shown in FIG. 12, in a combination furniture 2', a sofa group 30' is composed of the same main sofa and auxiliary sofa as the sofa group 30, but the arrangement of the main sofa and the like is different from that of the sofa group 30. Specifically, in the sofa group 30', the third main sofa 33 is placed on the right side of the first main sofa 31, the right side of the first main sofa 31 and the left side of the third main sofa 33 are overlapped without any gaps, the first auxiliary sofa 35 is placed on the right side of the third main sofa 33, and the right side of the third main sofa 33 and the left side of the first auxiliary sofa 35 are overlapped without any gaps, and the arrangement of the first auxiliary sofa 35, the second main sofa 32 and the second auxiliary sofa 36, ​​and the arrangement of the first main sofa 31, the fourth auxiliary sofa 38, the fourth main sofa 34 and the third auxiliary sofa 37 are the same as in the sofa group 30. In this case, the distance between the opposing second main sofa 32 and fourth main sofa 34, and the distance between the opposing second auxiliary sofa 36 and third auxiliary sofa 37, is increased by the width of the third main sofa 33, and the stool 40 is placed in the center of the space surrounded by the first main sofa 31, the third main sofa 33, the second main sofa 32, the fourth main sofa 34, the second auxiliary sofa 36 and the third auxiliary sofa 37.

[0041] This creates a certain amount of space around the stool 40, allowing adults to sit on each of the main sofas, auxiliary sofas, and stool 40, and also allowing adults to move around the stool 40. Since the seat of each main sofa and auxiliary sofa in the sofa group 30' is the same height as the seat of the stool 40, the person sitting on the main sofa or auxiliary sofa facing the person sitting on the stool 40 will be at the same eye height and can chat face-to-face. In addition, in the sofa group 30', the shapes of the inner circle 30L1 and outer circle 30L2 formed by the sofa group 30 are not significantly distorted, and a convex annular portion (outer circle 30L2) is provided on the outer periphery of a circular plate (inner circle 30L1) with a square hole (stool 40) in the center, and the image of an old coin with convex letters between each side of the square and the annular portion remains, and the arrangement of the fur group 30' and the stools 40 is excellent in terms of design.

[0042] As described above, the combination furniture 2 is composed of the stool 40 arranged in the center and the sofa group 30 (the first main sofa 31, the first auxiliary sofa 35, the second main sofa 32, the second auxiliary sofa 36, ​​the third main sofa 33, the third auxiliary sofa 37, the fourth main sofa 34, and the fourth auxiliary sofa 38) arranged around the stool 40, the stool 40 has a rectangular parallelepiped outer peripheral surface, each of the main sofas in the sofa group 30 has a central front surface that overlaps with each surface that is a part of the outer peripheral surface of the stool 40, each of the main sofas and each of the auxiliary sofas in the sofa group 30 has a backrest portion that is curved in an arc shape horizontally and outwardly, and when each of the main sofas and each of the auxiliary sofas are arranged around the stool 40, each of the main sofas The auxiliary sofas overlap the outer peripheral surface of the stool 40 without any gaps, leaving no empty space between the outer peripheral surface of the stool 40 and each of the main sofas, and the auxiliary sofas are arranged between the main sofas, and each main sofa and each adjacent auxiliary sofa overlap without any gaps, leaving no empty space between adjacent main sofas and auxiliary sofas.This prevents any empty space from being generated in the installation space for the sofa group 30 (first main sofa 31, first auxiliary sofa 35, second main sofa 32, second auxiliary sofa 36, ​​third main sofa 33, third auxiliary sofa 37, fourth main sofa 34, fourth auxiliary sofa 38) and the stool 40 when they are not in use or are on display, etc., and improves the efficiency of the installation space. [Industrial Applicability]
