[Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 5-146316 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] However, manufacturing a curved beam has problems that processing becomes complicated, and manufacturing cost and assembly cost increase.

[0005] Accordingly, the present invention has been made in view of the above circumstances, and provides a furniture with a top plate that allows a beam supporting the top plate to have a simple configuration. [Means for Solving the Problem]

[0006] To achieve the above object, the present invention employs the following means. In other words, the fixture with a top plate according to the present invention comprises a top plate having a front edge and a rear edge arranged opposite to each other in the front-rear direction, and a left edge and a right edge arranged opposite to each other in the left-right direction, and a lower support extending along the lower surface of the top plate, wherein at least a portion of the rear edge of the top plate in the left-right direction has a top formed to bulge towards the rear in a plan view, and the lower support comprises a first outer beam that gradually extends towards the top as it moves from the left edge to the right, a second outer beam that gradually extends towards the top as it moves from the right edge to the left, and a first inner beam positioned in front of the first outer beam and extending from the left edge to the right The structure comprises a beam and a second inner beam positioned in front of the second outer beam and extending to the left from the right edge, wherein the first inner beam extends linearly along the left-right direction, or extends inclined with respect to the left-right direction such that the inclination angle of the first inner beam with respect to the left-right direction is less than the inclination angle of the first outer beam with respect to the left-right direction, and the second inner beam extends linearly along the left-right direction, or extends inclined with respect to the left-right direction such that the inclination angle of the second inner beam with respect to the left-right direction is less than the inclination angle of the second outer beam with respect to the left-right direction.

[0007] In this type of fixture with a tabletop, at least a portion of the rear edge of the tabletop in the left-right direction has a apex that bulges outwards towards the rear in a plan view. A first inner beam and a second inner beam are positioned at the front of the tabletop. A first outer beam and a second outer beam, positioned at the rear of the tabletop, extend toward the apex. Even without making the first outer beam, second outer beam, first inner beam, and second inner beam into complexly shaped members, the lower support stably supports the tabletop by positioning the first outer beam and second outer beam along the rear edge of the tabletop. Therefore, the first outer beam, second outer beam, first inner beam, and second inner beam can be made into a simple structure, making assembly and construction easier.

[0008] Furthermore, in the fixture with a top plate according to the present invention, the first outer beam, the second outer beam, the first inner beam, and the second inner beam may be members that extend in a straight line.

[0009] In a fixture with a top plate configured in this way, the first outer beam, second outer beam, first inner beam, and second inner beam are members that extend in a straight line. Therefore, there is no need to make the first outer beam, second outer beam, first inner beam, and second inner beam curved, and the first outer beam, second outer beam, first inner beam, and second inner beam can be made into a simple configuration.

[0010] Furthermore, in the fixture with a top plate according to the present invention, the lower support is provided with an intermediate beam extending in the front-rear direction, and the right end of the first outer beam, the left end of the second outer beam, the right end of the first inner beam, and the left end of the second inner beam may be connected to the intermediate beam.

[0011] In this configuration of a fixture with a tabletop, the intermediate beam is positioned away from the left and right edges of the tabletop, extending in the front-to-back direction. The right end of the first outer beam, the left end of the second outer beam, the right end of the first inner beam, and the left end of the second inner beam are connected to the intermediate beam. Therefore, the tabletop support strength can be increased by using the first outer beam, the second outer beam, the first inner beam, the second inner beam, and the intermediate beam to support the tabletop.

[0012] Furthermore, the fixture with a tabletop according to the present invention may be provided with legs that are installed on the floor and support the intermediate beam.

[0015] In a fixture with a top plate configured in this way, at least a portion of the rear edge of the top plate in the left-right direction has a apex that bulges outwards towards the rear in a plan view. An inner beam is positioned at the front of the top plate. The first outer beam and the second outer beam, positioned at the rear of the top plate, extend toward the apex. Even without making the first outer beam, the second outer beam, and the inner beam into complex shapes, the lower support stably supports the top plate by positioning the first outer beam and the second outer beam along the rear edge of the top plate. Therefore, the first outer beam, the second outer beam, and the inner beam can be made into a simple configuration.

[0016] Furthermore, in the fixture with a top plate according to the present invention, the first outer beam, the second outer beam, and the inner beam may be members that extend in a straight line.

[0017] In a fixture with a top plate configured in this way, the first outer beam, the second outer beam, and the inner beam are members that extend in a straight line. Therefore, there is no need to make the first outer beam, the second outer beam, and the inner beam curved, and the first outer beam, the second outer beam, and the inner beam can be made into a simple configuration.

[0018] Furthermore, in the furniture with a top plate according to the present invention, the lower support may include an intermediate beam extending in the front-rear direction, and the right end portion of the first outer beam and the left end portion of the second outer beam may be connected to the intermediate beam.

[0019] In the furniture with a top plate configured as described above, the intermediate beam is arranged so as to extend in the front-rear direction at a position separated from the left edge and the right edge of the top plate. The right end portion of the first outer beam and the left end portion of the second outer beam are connected to the intermediate beam. Therefore, the first outer beam, the second outer beam and the intermediate beam can enhance the top plate supporting strength for supporting the top plate.

[0020] Furthermore, the furniture with a top plate according to the present invention may be provided with a leg portion that is installed on a floor surface and supports the intermediate beam.

[0021] In the furniture with a top plate configured as described above, the leg portion is installed on the floor surface and supports the intermediate beam. Therefore, the leg portion can stably support the top plate.

[0022] Furthermore, in the furniture with a top plate according to the present invention, at least a part of the front edge portion of the top plate in the left-right direction may have a recess formed to be recessed rearward in a plan view.

[0023] In the furniture with a top plate configured as described above, in the top plate in which a recess is formed in at least a part of the front edge portion of the top plate in the left-right direction so as to be recessed rearward in a plan view, the first outer beam and the second outer beam can have a simple configuration.

[0024] Furthermore, in the furniture with a top plate according to the present invention, the lower support may include a first side beam that supports the right edge portion of the top plate from below, and a second side beam that supports the left edge portion of the top plate from below.

[0025] In the furniture with a top plate configured as described above, the first side beam supports the right edge of the top plate from below. The second side beam supports the left edge of the top plate from below. Therefore, the first side beam and the second beam support the right edge and the left edge of the top plate, which can improve the support strength of the top plate. [Effects of the Invention]

[0065] As shown in Figure 1, among the multiple leg portions 7 and 8, leg portion 7 is referred to as the intermediate leg 7, and leg portion 8 is referred to as the end leg 8.

[0066] The intermediate legs 7 are positioned at three locations: the center of the tabletop member 10 in the left-right direction, the boundary between the tabletop member 10 and the tabletop member 20, and the boundary between the tabletop member 10 and the tabletop member 30. The legs 8 are positioned at two locations: to the right of the left edge 23 of the tabletop member 20, and to the left of the right edge 34 of the tabletop member 30.

[0067] Figure 4 is a side view of the central portion of the table system 100 in the left-right direction. Figure 5 is a perspective view showing the configuration of the connection between the first front and rear beams 41 and the intermediate legs 7. The intermediate leg 7, positioned in the center of the top plate member 10 in the left-right direction, will now be described. As shown in Figure 4, the intermediate leg 7 is positioned below the top plate member 10. The intermediate leg 7 supports the top plate member 10 from below. As shown in Figure 5, the intermediate leg 7 is connected to the first front and rear beams 41. The following illustrated examples are examples of the connection structure between the intermediate leg 7 and the first front and rear beams 41, and the connection structure between the first front and rear beams 41 and beams 51, 52, 53, and 54, and the connection structure between the intermediate leg 7 and the first front and rear beams 41, and beams 51, 52, 53, and 54 can be set as appropriate.

[0068] The intermediate leg 7 is formed in a T-shape when viewed from the left or right. The intermediate leg 7 has a pair of front and rear support columns 71 and a panel cover 73.

[0069] Each support column 71 is formed in a cylindrical shape extending vertically. Each support column 71 is installed on the floor surface via an adjuster 71a. In a cross-sectional view perpendicular to the vertical direction, each support column 71 is formed in a semi-elliptical shape with a flat inner end surface (opposite surfaces) in the front-rear direction and a projection on the outward side in the left-right direction. The upper end of each support column 71 is connected to the first front-rear beam 41 with screws (not shown). Note that there may be one support column 71, not just two. The cross-sectional shape of the support column 71 can also be set as appropriate. The middle of a pair of support columns 71 in the vertical direction is connected by a connecting member (not shown).

[0070] The panel cover 73 is detachably attached to the support column 71 from both the left and right sides. The panel cover 73 has a structure in which both the front and rear ends of the board material are bent.

[0071] Intermediate joints 60 are provided at both the front and rear ends of the first front and rear beams 41. The intermediate joints 60 are formed in a T-shape when viewed from above or below. Specifically, the intermediate joints 60 have an arm connecting portion 61, an outer casing portion 62, and a rod connecting portion 63.

[0072] The arm connecting portion 61 is formed in a rectangular tubular shape extending in the front-rear direction. The arm connecting portion 61 is inserted into both the front and rear ends of the cylindrical first front and rear beams 41. The arm connecting portion 61 and the first front and rear beams 41 are connected to each other by screws (not shown). The connection structure between the intermediate joint 60 and the first front and rear beams 41 can be set as appropriate.

[0073] The outer casing 62 is formed in a rectangular tubular shape extending in the left-right direction. The outer casing 62 is connected to the front end of the arm connecting portion 61, for example by welding. The rod connecting portion 63 extends in the left-right direction and is formed in a C-shape that opens downwards. The rod connecting portion 63 penetrates the outer casing 62 in the left-right direction. The rod connecting portion 63 is connected to the outer casing 62, for example by welding. Note that the rod connecting portion 63 is not limited to a C-shape and may be formed in a rectangular tubular shape or the like.

[0074] The rod connecting portion 63 is inserted through the first left and right beams 51, the second left and right beams 52, the third left and right beams 53, and the fourth left and right beams 54, which are formed in a rectangular tubular shape. The rod connecting portion 63 is screwed to the lower surface of the top plate unit 1 together with the first left and right beams 51, the second left and right beams 52, the third left and right beams 53, and the fourth left and right beams 54, respectively.

[0075] The upper end of the end leg 8 shown in Figure 1 is connected to the connection portion between the fifth left and right beam 55 and the fourth front and rear beam 44, the connection portion between the sixth left and right beam 56 and the fourth front and rear beam 44, the connection portion between the seventh left and right beam 57 and the fifth front and rear beam 45, and the connection portion between the eighth left and right beam 58 and the fifth front and rear beam 45.

[0076] In the table system 100 configured in this way, the center of the rear edge 12 of the tabletop member 10 in the left-right direction has a top portion 12a that bulges out towards the rear in a plan view. The third left and right beams 53 and the fourth left and right beams 54 are arranged at the front of the tabletop member 10. The first left and right beams 51 and the second left and right beams 52, which are arranged at the rear of the tabletop member 10, extend toward the top portion 12a. Even without making the first left and right beams 51, the second left and right beams 52, the third left and right beams 53 and the fourth left and right beams 54 into members with complex shapes, the lower support 4 stably supports the tabletop member 10 by arranging the first left and right beams 51 and the second left and right beams 52 along the rear edge 12 of the tabletop member 10. Therefore, the first left and right beams 51, the second left and right beams 52, the third left and right beams 53 and the fourth left and right beams 54 can have a simple configuration, making assembly and construction easier.

[0077] Furthermore, the first left and right beams 51, the second left and right beams 52, the third left and right beams 53, and the fourth left and right beams 54 are members that extend in a straight line. Therefore, there is no need to make the first left and right beams 51, the second left and right beams 52, the third left and right beams 53, and the fourth left and right beams 54 into curved members, and the first left and right beams 51, the second left and right beams 52, the third left and right beams 53, and the fourth left and right beams 54 can be made into a simple structure.

[0078] Furthermore, the first front and rear beams 41 are positioned away from the left edge 13 and right edge 14 of the top plate member 10, extending in the front-rear direction. The right end of the first left and right beams 51, the left end of the second left and right beams 52, the right end of the third left and right beams 53, and the left end of the fourth left and right beams 54 are connected to the first front and rear beams 41. Thus, the top plate support strength for supporting the top plate member 10 can be increased by the first left and right beams 51, the second left and right beams 52, the third left and right beams 53, the fourth left and right beams 54, and the first front and rear beams 41.

[0079] Furthermore, the intermediate legs 7 are installed on the floor and support the first front and rear beams 41. Thus, the intermediate legs 7 can stably support the top plate member 10.

[0080] Furthermore, in a top plate member 10 in which a recess 11a is formed in the center of the left-right direction of the front edge portion 11 of the top plate member 10 so as to be recessed toward the rear in a plan view, the first left and right beams 51 and the second left and right beams 52 can be made into a simpler structure.

[0081] Furthermore, the second front and rear beam 42 supports the right edge 14 of the top plate member 10 from below. The third front and rear beam 43 supports the left edge 13 of the top plate member 10 from below. Therefore, the second front and rear beam 42 and the third front and rear beam 43 support the right edge 14 and the left edge 13 of the top plate member 10, thereby increasing the top plate support strength.

[0082] The second front and rear beams 42 and the third front and rear beams 43 are members that extend in a straight line. Therefore, there is no need to make the second front and rear beams 42 and the third front and rear beams 43 curved members, and the second front and rear beams 42 and the third front and rear beams 43 can be made into a simple structure.

[0083] (Second Embodiment) Next, a table of a second embodiment of the present invention will be described, mainly with reference to Figure 6. In the embodiments described below, components corresponding to the embodiments shown above may be denoted by the same reference numerals and their descriptions may be omitted.

[0084] Figure 6 is a view from above of a fixture with a tabletop according to the second embodiment of the present invention, with the tabletop unit indicated by dashed lines. As shown in Figure 6, in the table system 100A, the third left and right beams (first inner beam) 53A and the fourth left and right beams (second inner beam) 54A are inclined with respect to the left and right directions.

[0085] The third left and right beams 53A are positioned in front of the center of the top plate member 10 in the front-to-back direction. The third left and right beams 53A are positioned in front of the first left and right beams 51. The third left and right beams 53A are positioned behind the front edge 11 of the top plate member 10. The third left and right beams 53A are inclined in the left-to-right direction, gradually moving towards the rear as they move from the left edge 13 side of the top plate member 10 toward the right side. The inclination angle of the third left and right beams 53A in the left-to-right direction is less than the inclination angle of the first left and right beams 51 in the left-to-right direction. The third left and right beams 53A are not inclined towards the rear as much as the first left and right beams 51. The third left and right beams 53A are not inclined in the left-to-right direction to the extent that they are parallel to the first left and right beams 51. The third left and right beams 53A are members that extend in a straight line. The left end of the third left and right beams 53A is connected to the second front and rear beams 42. The right end of the third left / right beam 53A is connected to the first front / rear beam 41. The third left / right beam 53A is fixed to the underside of the top plate member 10.

[0086] The fourth left and right beams 54A are positioned in front of the center of the top plate member 10 in the front-to-back direction. The fourth left and right beams 54A are positioned in front of the second left and right beams 52. The fourth left and right beams 54A are positioned behind the front edge 11 of the top plate member 10. The fourth left and right beams 54A are inclined in the left-to-right direction so that they gradually move towards the rear as they move from the right edge 14 side of the top plate member 10 toward the left side. The inclination angle of the fourth left and right beams 54A in the left-to-right direction is less than the inclination angle of the second left and right beams 52 in the left-to-right direction. The fourth left and right beams 54A are not inclined to the rear as much as the second left and right beams 52. The fourth left and right beams 54A are not inclined to the left-to-right direction to the extent that they are parallel to the second left and right beams 52. The fourth left and right beams 54A are members that extend in a straight line. The right end of the fourth left and right beams 54A is connected to the third front and rear beams 43. The left end of the fourth left / right beam 54A is connected to the first front / rear beam 41. The fourth left / right beam 54 is fixed to the lower surface of the top plate member 10.

[0087] In the table system 100A configured in this way, at least a portion of the rear edge 12 of the tabletop member 10 in the left-right direction has a top portion 12a formed to bulge outwards towards the rear in a plan view. The third left-right beam 53A and the fourth left-right beam 54A are arranged at the front of the tabletop member 10. The first left-right beam 51 and the second left-right beam 52, which are arranged at the rear of the tabletop member 10, extend toward the top portion 12a. Even without making the first left-right beam 51, the second left-right beam 52, the third left-right beam 53A and the fourth left-right beam 54A into members with complex shapes, the lower support 4 stably supports the tabletop member 10 by arranging the first left-right beam 51 and the second left-right beam 52 along the rear edge 12 of the tabletop member 10. Therefore, the first left-right beam 51, the second left-right beam 52, the third left-right beam 53A and the fourth left-right beam 54A can have a simple configuration, making assembly and construction easier.

[0088] (Third embodiment) Next, the table of the third embodiment of the present invention will be described mainly with reference to Figure 7.

[0089] Figure 7 is a view from above of a fixture with a tabletop according to the third embodiment of the present invention, with the tabletop unit indicated by dashed lines. As shown in Figure 7, in the table system 100B, the tabletop member (tabletop) 10B, which is positioned between the tabletop member 20B and the tabletop member 30B, has a front edge 11B, a rear edge 12B, a left edge 13B, and a right edge 14B.

[0090] The front edge portion 11B is the front edge of the top plate member 10 in a plan view. The front edge portion 11B is formed in a straight line extending in the left-right direction. The front edge portion 11B is arranged parallel to the third left-right beam 53 and the fourth left-right beam 54. The first left-right beam 51 and the second left-right beam 52 may be arranged below the front edge portion 11B.

[0091] The rear edge portion 12B is the rear edge portion of the top plate member 10 in a plan view. The rear edge portion 12B is formed such that its center in the left-right direction is convex toward the rear. The center of the rear edge portion 12B in the left-right direction has a apex portion 12b that bulges toward the rear in a plan view. The rear edge portion 12B has a shape that gradually extends toward the rear as it moves from the left-right end toward the center in the left-right direction. The rear edge portion 12B is formed in a straight line and has a pointed shape toward the rear at the apex portion 12b in the center in the left-right direction. The rear edge portion 12B has a symmetrical shape toward the center in the left-right direction. In the illustrated example, the inclination angle of the rear edge portion 12B with respect to the left-right direction is greater than the inclination angle of the first left-right beam 51 and the second left-right beam 52 with respect to the left-right direction. Note that the inclination angle of the rear edge portion 12B with respect to the left-right direction may be smaller than the inclination angle of the first left-right beam 51 and the second left-right beam 52 with respect to the left-right direction. The first left and right beams 51 and the second left and right beams 52 may be parallel to the trailing edge portion 12B and positioned below the trailing edge portion 12B.

[0092] The left edge 13B connects the left end of the leading edge 11B to the left end of the trailing edge 12B. The right edge 14B connects the right end of the leading edge 11B to the right end of the trailing edge 12B.

[0093] The front edge 21B of the top plate member 20B and the front edge 31B of the top plate member 30B are formed in a straight line that is continuous with the front edge 11B of the top plate member 10B. The rear edge 22B of the top plate member 20B and the rear edge 32B of the top plate member 30B are formed in a straight line that is continuous with the rear edge 12B of the top plate member 10B.

[0094] In the table system 100B configured in this way, the center of the rear edge portion 12B of the tabletop member 10B in the left-right direction has a top portion 12b that is formed to bulge outwards towards the rear in a plan view. The third left and right beams 53 and the fourth left and right beams 54 are arranged at the front of the tabletop member 10B. The first left and right beams 51 and the second left and right beams 52, which are arranged at the rear of the tabletop member 10B, extend toward the top portion 12b. Even without making the first left and right beams 51, the second left and right beams 52, the third left and right beams 53 and the fourth left and right beams 54 into members with complex shapes, the lower support 4 stably supports the tabletop member 10B by arranging the first left and right beams 51 and the second left and right beams 52 along the rear edge portion 12B of the tabletop member 10B. Therefore, the first left and right beams 51, the second left and right beams 52, the third left and right beams 53 and the fourth left and right beams 54 can have a simple configuration, making assembly and construction easier.

[0095] (Fourth Embodiment) Next, the table of the fourth embodiment of the present invention will be described mainly with reference to Figure 8.

[0096] Figure 8 is a view from above of a fixture with a tabletop according to the fourth embodiment of the present invention, with the tabletop unit indicated by dashed lines. As shown in Figure 8, in the table system 100C, the tabletop member (tabletop) 10C, which is positioned between the tabletop member 20C and the tabletop member 30C, has a front edge 11B, a rear edge 12, a left edge 13C, and a right edge 14C.

[0097] The front edge portion 11B is formed in a straight line extending in the left-right direction, as shown in the top plate member 10B of the second embodiment. The rear edge portion 12 is formed in an arc shape, as shown in the top plate member 10 of the first embodiment. The left edge portion 13C connects the left end of the front edge portion 11B and the left end of the rear edge portion 12C. The right edge portion 14C connects the right end of the front edge portion 11B and the right end of the rear edge portion 12C.

[0098] The front edge 21C of the top plate member 20C is formed in a straight line that is continuous with the front edge 11B of the top plate member 10C. The rear edge 22C of the top plate member 20C is formed in a curved shape that is continuous with the rear edge 12C of the top plate member 10C. The left edge 23C of the top plate member 20C is formed in a curved shape that connects the left end of the front edge 21C and the left end of the rear edge 22C.

[0099] The front edge 31C of the top plate member 30C is formed in a straight line that is continuous with the front edge 11B of the top plate member 10C. The rear edge 32C of the top plate member 30C is formed in a curved shape that is continuous with the rear edge 12C of the top plate member 10C. The right edge 34C of the top plate member 30C is formed in a curved shape that connects the right end of the front edge 31C and the right end of the rear edge 22C.

[0100] In the table system 100C configured in this way, the center of the rear edge portion 12C of the tabletop member 10C in the left-right direction has a top portion 12a formed to bulge outwards towards the rear in a plan view. The third left and right beams 53 and the fourth left and right beams 54 are arranged at the front of the tabletop member 10C. The first left and right beams 51 and the second left and right beams 52, which are arranged at the rear of the tabletop member 10C, extend toward the top portion 12a. Even without making the first left and right beams 51, the second left and right beams 52, the third left and right beams 53 and the fourth left and right beams 54 into members with complex shapes, the lower support 4 stably supports the tabletop member 10C by arranging the first left and right beams 51 and the second left and right beams 52 along the rear edge portion 12C of the tabletop member 10C. Therefore, the first left and right beams 51, the second left and right beams 52, the third left and right beams 53 and the fourth left and right beams 54 can have a simple configuration, making assembly and construction easier.

[0101] (Fifth embodiment) Next, a table of the fifth embodiment of the present invention will be described mainly with reference to Figure 9.

[0102] Figure 9 is a view from above of a fixture with a tabletop according to the fifth embodiment of the present invention, with the tabletop unit indicated by dashed lines. As shown in Figure 9, in the table system 100D, the left and right beams (inner beams) 59 support the lower surface of the front part of the tabletop member 10. The left and right beams 59 are positioned in front of the center of the tabletop member 10 in the front-to-back direction. The left and right beams 59 are positioned in front of the first left and right beams 51 and the second left and right beams 52. The left and right beams 59 are positioned behind the front edge 11 of the tabletop member 10. The left and right beams 59 extend in the left-to-right direction from the left edge 13 to the right edge 14 of the tabletop member 10. The left and right beams 59 are linearly extending members. The left end of the left and right beams 59 is connected to the second front and rear beam 42. The right end of the left and right beams 59 is connected to the first front and rear beam 41. The left and right beams 59 are fixed to the lower surface of the tabletop member 10. A notch is formed in the front part of the first front and rear beam 41, and the left and right beams 59 are positioned in this notch. Furthermore, the first front and rear beams 41 may be divided at the front, and the first front and rear beams 41 may be positioned at the division point.

[0103] In the table system 100D configured in this way, the center of the rear edge 12 of the tabletop member 10 in the left-right direction has a top portion 12a that bulges out towards the rear in a plan view. Left and right beams 59 are arranged at the front of the tabletop member 10. The first left and right beams 51 and the second left and right beams 52, which are arranged at the rear of the tabletop member 10, extend toward the top portion 12a. Even without making the first left and right beams 51, the second left and right beams 52 and the left and right beams 59 into members with complex shapes, the lower support 4 stably supports the tabletop member 10 by arranging the first left and right beams 51 and the second left and right beams 52 along the rear edge 12 of the tabletop member 10. Therefore, the first left and right beams 51, the second left and right beams 52 and the left and right beams 59 can have a simple configuration, making assembly and construction easier.

[0104] Furthermore, the first left and right beams 51, the second left and right beams 52, and the left and right beams 59 are members that extend in a straight line. Therefore, there is no need to make the first left and right beams 51, the second left and right beams 52, and the left and right beams 59 curved members, and the first left and right beams 51, the second left and right beams 52, and the left and right beams 59 can be made into a simple structure.

[0105] Furthermore, the first front and rear beams 41 are positioned away from the left edge 13 and right edge 14 of the top plate member 10, and extend in the front-rear direction. The right end of the first left and right beams 51 and the left end of the second left and right beams 52 are connected to the first front and rear beams 41.
