[0023] Hereinafter, a bench according to an embodiment of the present invention will be described with reference to the drawings. In the bench according to this embodiment, each seat plate can be easily attached and detached. It is also possible to attach a top plate instead of the seat plate. The seat plate and the top plate can be attached and detached without tools.

[0024] 1 to 5 are diagrams showing an example of a bench 10 according to this embodiment. The bench 10 has a bench frame 11 and three seat panels 12, namely, a first seat panel 13, a second seat panel 14, and a third seat panel 15. Each seat panel has a rectangular seating surface and serves as a seat.

[0025] The bench frame 11 has a first front leg 16, a second front leg 17, a first rear leg 18, a second rear leg 19, a first leg through hole 21, a second leg through hole 22, a base through hole 23, a first side panel 24, a second side panel 25, a first front panel 26, a second front panel 27, a first rear panel 28, and a second rear panel 29. These may be made of metal, for example.

[0026] The first front leg 16, the second front leg 17, the first rear leg 18, and the second rear leg 19 are pillars that extend in the height direction as legs, and are located at the four corners of a rectangular seat frame 31 on which the seat panel 12 is placed. The first front leg 16, the second front leg 17, the first rear leg 18, and the second rear leg 19 are all at the same height, and their upper surfaces form part of the seat frame 31.

[0027] The first leg through hole 21 and the second leg through hole 22 are reinforcing members that extend in the depth direction. The first leg through hole 21 connects the first front leg 16 and the first rear leg 18 at their lower sides. The second leg through hole 22 connects the second front leg 17 and the second rear leg 19 at their lower sides. Furthermore, the first leg through hole 21 and the second leg through hole 22 are connected at their lower sides by a ground through hole 23 that extends in the width direction. The ground through hole 23 is located approximately in the center of the first leg through hole 21 and the second leg through hole 22 in the depth direction, and the ground through hole 23 is also a reinforcing member.

[0028] The first side panel 24 and the second side panel 25 are beams extending in the depth direction. The first side panel 24 and the second side panel 25 are a pair of opposing panel members. The first side panel 24 connects the first front leg 16 and the first rear leg 18 at the upper side. The second side panel 25 connects the second front leg 17 and the second rear leg 19 at the upper side. The upper surfaces of the first side panel 24 and the second side panel 25 are flush with the upper surfaces of the first front leg 16, the second front leg 17, the first rear leg 18, and the second rear leg 19, and form part of the seat frame 31.

[0029] The first front curtain board 26, the second front curtain board 27, the first rear curtain board 28, and the second rear curtain board 29 are beams extending in the width direction. The first front curtain board 26 and the first rear curtain board 28 are a pair of opposing curtain boards. The first front curtain board 26 and the second front curtain board 27 connect the first front leg 16 and the second front leg 17 at their upper sides. The first front curtain board 26 is located above the second front curtain board 27, and the underside of the first front curtain board 26 abuts against the upper side of the second front curtain board 27. The first rear curtain board 28 and the second rear curtain board 29 connect the first rear leg 18 and the second rear leg 19 at their upper sides. The first rear curtain board 28 is located above the second rear curtain board 29, and the underside of the first rear curtain board 28 abuts against the upper side of the second rear curtain board 29. The upper surfaces of the first front curtain board 26 and the first rear curtain board 28 are flush with the upper surfaces of the first front leg 16, the second front leg 17, the first rear leg 18, the second rear leg 19, the first side curtain board 24 and the second side curtain board 25, and form part of the seat frame 31.

[0030] As shown in FIGS. 4 and 5 , the bench frame 11 is provided with six rods 32, namely, a first rod 33, a second rod 34, a third rod 35, a fourth rod 36, a fifth rod 37, and a sixth rod 38. The rods 32 are elongated bar-shaped members with a substantially circular cross section. The rods 32 extend between the first side panel 24 and the second side panel 25 and are fixed, for example, substantially parallel to the first side panel 24 and the second side panel 25, between the first front panel 26 and the first rear panel 28. The first rod 33 and the second rod 34 form a first pair, the third rod 35 and the fourth rod 36 form a second pair, and the fifth rod 37 and the sixth rod 38 form a third pair. One seat panel 12 can be attached to each pair. For example, a first seat plate 13 is attached to the first pair, a second seat plate 14 is attached to the second pair, and a third seat plate 15 is attached to the third pair.

[0031] FIG. 6 is a diagram showing an example of a cross section of the seat panel 12 (first seat panel 13, second seat panel 14, and third seat panel 15). The seat panel 12 has, for example, a bottom panel member 39, an internal cushion member 41, and a cover member 42 that forms the seat surface. The panel member 39 may be plywood. The cushion member 41 may be chip urethane. The cover member 42 may be slab urethane. The cover member 42 may be replaceable.

[0032] The plate member 39 is provided with a seat plate fitting portion 43 for attaching the seat plate 12 to the rod 32. Fig. 6 shows fitting members 46 and 47 attached to the plate member 39 via attachments 44 and 45. The fitting members may be made of, for example, resin.

[0033] As shown in FIG. 4, four fitting members 51, 52, 53, and 54 are provided on the back surface 48 of the first seat panel 13 as the seat panel fitting portion 43. The fitting members 51, 52, 53, and 54 have a substantially cylindrical inner peripheral surface that can fit onto the outer peripheral surface of the rod 32. In other words, the fitting members 51, 52, 53, and 54 are receiving members having a substantially semicircular cross section. The fitting members 51 and 53 form a pair and are fixed to the back surface 48 while being aligned in the depth direction of the bench 10 so that they can be attached to and detached from the same rod (e.g., the first rod 33). The fitting members 52 and 54 also form a pair and are fixed to the back surface 48 while being aligned in the depth direction of the bench 10 so that they can be attached to and detached from the same rod (e.g., the second rod 34).

[0034] Similarly, four fitting members 56, 57, 58, and 59 are attached to the back surface 55 of the second seat plate 14 as a seat plate fitting portion 43. The fitting members 56 and 58 form a pair and are detachable from the same rod (for example, the third rod 35), and the fitting members 57 and 59 form a pair and are detachable from the same rod (for example, the fourth rod 36). Similarly, four fitting members 62, 63, 64, and 65 are attached to the back surface 61 of the third seat plate 15 as a seat plate fitting portion 43. The fitting members 62 and 64 form a pair and are detachable from the same rod (for example, the fifth rod 37), and the fitting members 63 and 65 form a pair and are detachable from the same rod (for example, the sixth rod 38).

[0035] 1 to 5, the outer edge of the seat panel 12 is located inside the outer periphery of the seat frame 31. In addition, the outer edge of the seat panel 12 is located outside the inner periphery of the seat frame 31.

[0036] In this embodiment, the seat panels 12 of the bench 10 are detachable from the seat frame 31 independently of each other, and no tools are required for attachment or detachment. Attachment and detachment of the seat panel 12 will be described below, taking the attachment and detachment of the first seat panel 13 as an example.

[0037] 7 to 9 are diagrams illustrating the attachment and detachment of the first seat plate 13. The first seat plate 13 is attached to the upper side of the seat frame 31 by aligning the fitting members 51 and 53 on the back surface 48 with the first rod 33 and fitting them from above, and aligning the fitting members 52 and 54 on the back surface 48 with the second rod 34 and fitting them from above, so that the inner peripheral surfaces of the fitting members 51, 52, 53, and 54 expand slightly outward and fit along the outer peripheral surfaces of the first rod 33 and the second rod 34. When removing the first seat plate 13, the back surface 48 is pushed up, so that the inner peripheral surfaces of the fitting members 51, 52, 53, and 54 expand slightly outward, disengaging the fitting members 51 and 53 from the first rod 33 and disengaging the fitting members 52 and 54 from the second rod 34.

[0038] In the bench 10 of this embodiment, a tabletop 66 can be attached to the seat frame 31 instead of the seat plate 12. In the bench 10 shown in Fig. 10, a first seat plate 13 and a third seat plate 15 are arranged on the left and right sides of the seat frame 31, respectively, and the tabletop 66 is arranged in the center. The tabletop 66 may be of the same size (width and depth) as the seat plate 12, and an upper surface 67 of the tabletop 66 forms a flat table surface.

[0039] As shown in Fig. 10, when the top plate 66 is placed on the seat frame 31, the second seat plate 14 can be stored on the back side of the seat frame 31. Fig. 11 is a diagram for explaining the attachment of the second seat plate 14 to the back side of the seat frame 31. The second seat plate 14 is attached to the underside of the seat frame 31, for example, by aligning the fitting members 56, 58 on the back surface 55 of the second seat plate 14 with the third rod 35 and fitting them from below, and aligning the fitting members 57, 59 on the back surface 55 with the fourth rod 36 and fitting them from below, so that the inner peripheral surfaces of the fitting members 56, 57, 58, 59 expand slightly outward and fit along the outer peripheral surfaces of the third rod 35 and the fourth rod 36. When removing, by pressing down on the back surface 55, the inner surfaces of the engaging members 56, 57, 58, and 59 expand slightly outward, disengaging the engaging members 56 and 58 from the third rod 35 and disengaging the engaging members 57 and 59 from the fourth rod 36.

[0040] Like the seat panel 12, the top panel 66 can also be stored on the back side. For example, when the second seat panel 14 is placed in the center of the seat frame 31 as shown in Figure 1, the top panel 66 can be stored on the back side of the seat frame 31. Figure 12 is a diagram for explaining how the top panel 66 is attached to the back side of the seat frame 31.

[0041] Four fitting members 71, 72, 73, and 74 are attached to the back surface 68 of the top plate 66 as a top plate fitting portion 69. The fitting members 71, 72, 73, and 74 have a substantially cylindrical inner peripheral surface that can fit onto the outer peripheral surface of the rod 32. In other words, the fitting members 71, 72, 73, and 74 are receiving members having a substantially semicircular cross section. The fitting members 71 and 73 form a pair and are fixed to the back surface 68 with their positions aligned in the depth direction so that they can be attached to and detached from the same rod (e.g., the third rod 35). The fitting members 72 and 74 also form a pair and are fixed to the back surface 68 with their positions aligned in the depth direction so that they can be attached to and detached from the same rod (e.g., the fourth rod 36).

[0042] The outer edge of the top plate 66 is located inside the outer periphery of the seat frame 31. In addition, the outer edge of the top plate 66 is located outside the inner periphery of the seat frame 31.

[0043] The seat panel fitting portion 43 and the top panel fitting portion 69 are arranged offset from each other in the extension direction of the rod 32, that is, in the depth direction of the bench 10. Therefore, the seat panel 12 and the top panel 66 can be attached to the upper and lower sides of the same rod 32 at the same time.

[0044] 13, even if the seat plate fitting portion 43 and the top plate fitting portion 69 are at the same position in the extension direction of the rod 32 when attached to the upper side of the seat frame 31, by inverting them when attached to the lower side of the seat frame 31, the seat plate fitting portion 43 and the top plate fitting portion 69 will be positioned offset from each other in the extension direction of the rod 32, and the seat plate fitting portion 43 and the top plate fitting portion 69 can be attached simultaneously to the upper and lower sides of the same rod 32. In this case, it is also possible to attach seat plates 12 simultaneously to the upper and lower sides of the same rod 32.

[0045] The position of the table top 66 is not limited to the center, and may be located at the end. Fig. 14 is a perspective view showing an example of a bench in which the table top 66 is provided on the left of the seat frame 31, the second seat panel 14 is provided in the center, and the third seat panel 15 is provided on the right.

[0046] 15 is an enlarged front view showing an example of the concealing member 75 of the seat panel 12 stored on the back side. The concealing member 75 can conceal the seat panel 12 or the top panel 66, and may be made of, for example, sheet metal. The concealing member 75 may be L-shaped. The concealing member 75 covers the side of the seat panel 12 or the top panel 66.

[0047] As described above, in this embodiment, the back surfaces 48, 55, and 61 of the first seat panel 13, second seat panel 14, and third seat panel 15 arranged on the seat frame 31 are provided with seat panel fitting portions 43 that detachably fit onto the rod 32 that spans between a pair of opposing headboards of the seat frame 31. This makes it possible to provide a bench that allows individual seat panels to be easily attached and detached. The back surface 68 of the top panel 66 is also provided with a top panel fitting portion 69 that detachably fit onto the rod 32 that spans between a pair of opposing headboards of the seat frame 31. This makes it possible to provide a bench that allows the top panel to be easily attached and detached. The seat panel fitting portions 43 and the top panel fitting portions 69 have inner peripheral surfaces that fit the outer peripheral surfaces of the rod 32, allowing for easy attachment and detachment without the need for tools. Attachment and detachment can be easily performed even by non-specialized workers.

[0048] For example, as shown in FIG. 10, if a first seat panel 13 and a third seat panel 15 are placed on the left and right, respectively, and a top panel 66 is placed in the center, the seats can be spaced apart, which is effective in ensuring social distancing.

[0049] Furthermore, one seat plate 12 is provided with a plurality of fitting members as seat plate fitting portions 43, and each fitting member is attached to a different rod, so that the seat plate 12 can be firmly fixed.

[0050] In this embodiment, the rod 32 extends in the depth direction between the first side curtain board 24 and the second side curtain board 25. By attaching the seat board 12 to the rod 32 that extends in the depth direction shorter than the width direction of the seat frame 31, the rod 32 is less likely to bend.

[0051] The seat panel fitting portion 43 and the top panel fitting portion 69 can be fitted to the rod 32 on the upper or lower side of the seat frame 31, allowing unused seat panels 12 or top panels 66 to be stored below the seat frame 31. In particular, the seat panel fitting portion 43 and the seat panel fitting portion 43 or top panel fitting portion 69, which are provided on the upper and lower sides of the rod 32, are offset from each other in the extension direction of the rod 32. This allows seat panels 12 to be attached to each other, or the seat panel 12 and top panel 66 to be attached to the upper and lower sides of the same rod 32 at the same time. For example, as shown in FIG. 10 , when the first seat panel 13 and the third seat panel 15 are arranged on the left and right, respectively, and the top panel 66 is arranged in the center, the unused second seat panel 14 is attached to the lower side of the rod 32, so there is no need to worry about where to store the second seat panel 14. This allows for storage of unused seat panels 12. 1, even when used as a normal bench, the unused tabletop 66 is attached to the underside of the rod 32, so there is no need to worry about where to store the tabletop 66. A storage space for the unused tabletop 66 can be secured.

[0052] By positioning the outer edges of the seat board 12 and the top board 66 more inward than the outer periphery of the seat frame 31, people or objects (e.g., shopping carts or strollers) are less likely to collide with the seat board 12 and the top board 66, reducing the possibility of damage to the seat board 12 and the top board 66.

[0053] By positioning the outer edges of the seat plate 12 and the top plate 66 outside the inner periphery of the seat frame 31, the seat plate 12 and the top plate 66 can be hung on the upper surface of the seat frame 31, reducing deflection of the seat plate 12 and the top plate 66 and providing stable support.

[0054] By providing a blind member 75 for the seat board 12 or the top board 66 attached to the underside of the seat frame 31, the seat board 12 or the top board 66 stored on the underside is hardly visible from the side, and a good-looking bench can be provided.

[0055] The bench frame 11 has a ground support 23 located approximately in the center of the first leg through 21 and the second leg through 22 in the depth direction and connecting the first leg through 21 and the second leg through 22, so that people and objects are less likely to collide with the ground support 23 and the bench frame 11 is less likely to be damaged while maintaining the strength of the bench frame 11.

[0056] 16 to 18 are views showing a bench 80 according to a modified example of this embodiment. Components of the bench 80 that are the same as those of the bench 10 are given the same reference numerals. The bench 80 has a bench frame 11 and three seat plates 81, namely, a first seat plate 82, a second seat plate 83, and a third seat plate 84.

[0057] The bench frame 11 is provided with two rods 85, namely, a first rod 86 and a second rod 87. The rod 85 is a long, thin bar-shaped member with a substantially circular cross section. The rod 85 spans between the first front panel 26 and the first rear panel 28, which are a pair of opposing panel heads of the seat frame 31, and is fixed, for example, between the first side panel 24 and the second side panel 25, substantially parallel to the first front panel 26 and the first rear panel 28. The first seat panel 82, the second seat panel 83, and the third seat panel 84 are attached to the first rod 86 and the second rod 87.

[0058] Four fitting members 91, 92, 93, and 94 are attached to the back surface 88 of the first seating surface 82 as seat plate fitting portions 89. The fitting members 91, 92, 93, and 94 have a substantially cylindrical inner surface that can fit onto the outer circumferential surface of the rod 85. In other words, the fitting members 91, 92, 93, and 94 are receiving members having a substantially semicircular cross section. The fitting members 91 and 93 form pairs and are fixed to the back surface 88 with their widthwise alignment so that they can be attached to and detached from the same rod (for example, the first rod 86). The fitting members 92 and 94 form pairs and are fixed to the back surface 88 with their widthwise alignment so that they can be attached to and detached from the same rod (for example, the second rod 87). Similarly, four fitting members are attached to the second seating surface 83 and the third seating surface 84 as seat plate fitting portions 89.

[0059] The first seat plate 82 is attached to the upper side of the seat frame 31 by aligning the fitting members 91 and 93 on the back surface 88 with the first rod 86 and fitting them from above, and by aligning the fitting members 92 and 94 on the back surface 88 with the second rod 87 and fitting them from above. When removing the first seat plate 82, the back surface 88 is pushed up to release the fitting between the fitting members 91 and 93 and the first rod 86, and the fitting members 92 and 94 and the second rod 87.

[0060] In bench 80, a seat panel fitting portion 89 that detachably fits onto a rod 85 that spans between a pair of opposing skirting boards of seat frame 31 is provided on the backside of each of first seat panel 82, second seat panel 83, and third seat panel 84 that are arranged on seat frame 31. This makes it possible to provide a bench in which the individual seat panels can be easily attached and detached. As seat panel fitting portion 89 has an inner peripheral surface that fits onto the outer peripheral surface of rod 85, it can be easily attached and detached without tools.

[0061] Although the embodiments of the present invention have been described above, various modifications and variations are possible without departing from the spirit of the present invention. For example, the number of seat panels is not limited to three, and a bench may have multiple seat panels that can be individually attached and detached.
