Therefore, the table can be easily used.

  Note that the above table can be arbitrarily changed in design as long as it meets the gist of the claims. An example of the design change will be described below. FIG. 5 is a diagram showing a state in which the table of the design change example is arranged with the chair, where (a) is a front view, (b) is a side view, and FIG. 6 is a state in which the table of the design change example is arranged with the chair. FIG. 7 is a bottom view showing a state in which the table of the same design change example is arranged with a chair, FIG. 8 is a bottom view showing the chair accommodation state of the table of the same design change example, and FIG. 9 is another design change. FIG. 10 is a bottom view showing a state in which the table of the design change example is placed with the chair, and FIG. 11 shows a state in which the table chair in the design change example is stored. It is a bottom view shown.

  The outer top plates 200a and 200b can be arbitrarily designed as long as they are provided at both ends of the central top plate 100 so as to be openable and closable. For example, it is possible to adopt a form in which the outer top plates are closed on the lower surface of the central top plate 100. In addition, it is arbitrary whether an accommodating part is provided in an outer side top plate.

  The center leg 300 can be omitted as shown in FIGS. 5, 6, 7 and 8. In addition, the central leg may be changed in design as long as it is foldable or detachably provided on the central top plate and can support the central top plate.

  Further, the outer legs 400a and 400b may be changed in design as long as the outer legs 400a and 400b are foldably or detachably provided on the outer top plate and can support the outer top plate. For example, as shown in FIGS. 9, 10, and 11, the outer legs 400 a ′ and 400 b ′ may have a pair of legs having the same configuration as the center leg 300. In this case, the outer leg portions 400a ′ and 400b ′ of the second and third accommodating portions 210a and 210b of the outer top plates 200a and 200b are reduced, so that the second and third accommodating portions 210a and 210b can be reduced. Space for accommodating other objects increases. Therefore, the chaise longue 600 or the like can be accommodated in the space. In addition, if the space is used together with the first accommodating portion 110 of the central top plate 100, various objects can be accommodated, so that the capacity of the table is increased.
