[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the rearrangeable furniture according to the present invention will be described below with reference to the accompanying drawings. In the following description, a sofa is taken as an example of the rearrangeable furniture. EXAMPLES

[0010] 1 to 9, rearrangeable furniture (hereinafter simply referred to as furniture) 10 according to the embodiment comprises a lower unit 12, an upper unit 14 disposed on the lower unit 12, and an attachment 16 disposed on the upper unit 14. The furniture 10 also comprises a support 18 that supports the attachment 16. The attachment 16 in the embodiment is supported by two supports 18, 18 provided separately on the left and right.

[0011] The lower unit 12 of the embodiment is configured by covering a frame of wood or the like with an exterior material such as cloth (see FIG. 8), and has a rectangular shape in a plan view that is long in the left-right direction. The lower unit 12 is supported by legs 20 provided at the four corners (see FIG. 4). The lower unit 12 is provided with a groove-shaped mounting portion 22 into which the support body 18 can be inserted. The mounting portion 22 opens on the upper surface of the lower unit 12 and extends in the left-right direction. The mounting portion 22 is preferably provided forward of the center in the front-rear direction of the lower unit 12 (see FIG. 8). As shown in FIGS. 10 and 11, the mounting portion 22 may be provided forward of the center in the front-rear direction of the lower unit 12, or may be provided in the center. Front and rear walls 24 that are arranged opposite each other and form the mounting portion 22 are made of a rigid material such as wood.

[0012] The upper unit 14 of the embodiment constitutes the seat surface (the design surface of the furniture) on which the user sits in the furniture 10, and it is preferable to use a cushion that is softer than that of the lower unit 12. The upper unit 14 has a rectangular shape in plan view that is elongated in the left-right direction like the lower unit 12 (see FIG. 3). As shown in FIGS. 1 to 3, the upper unit 14 is disposed so as to overlap the upper side of the mounting portion 22 provided on the lower unit 12, and the upper unit 14 hides the mounting portion 22. In the embodiment, the upper unit 14 is disposed so as to overlap the lower unit 12 so as to cover the entire upper surface of the lower unit 12. The upper unit 14 may be prevented from slipping by a hook-and-loop fastener provided between the lower unit 12 and the upper unit 14. Here, when a hook-and-loop fastener is provided, it is preferable to place it away from the position through which the insertion portion 26 of the support body 18, which will be described later, passes.

[0013] The attachment 16 is a member that provides a predetermined function to the user of the furniture 10, and the attachment 16 in the embodiment is a backrest (see Figs. 1 to 3). The attachment 16 in the embodiment is disposed on the rear side of the upper surface of the upper unit 14 (see Fig. 3). For example, a table-type attachment 36 shown in Fig. 12 may be added or replaced with another type of attachment that has a different function from the backrest or has the same function as the attachment 16 in the embodiment but has a different backrest height. The furniture 10 can be provided with not only one attachment 16, but also multiple attachments 16, 36 (see Fig. 12). In this way, the furniture 10 can be provided with various types and numbers of attachments 16, 36, and can easily provide usage according to the attachments 16, 36.

[0014] As shown in Figs. 8 and 9, the support 18 has an insertion portion 26 disposed between the lower unit 12 and the upper unit 14, and a connecting portion 28 connecting the insertion portion 26 and the attachment 16. The connecting portion 28 extends in a direction (vertical direction) intersecting with the horizontally extending insertion portion 26, rises along the peripheral wall surface of the upper unit 14, and connects to the attachment 16. The support 18 has a hook portion 30 extending in a direction intersecting with the insertion portion 26 and hooked onto the lower unit 12 (see Fig. 8). The hook portion 30 of the embodiment extends downward from the tip of the insertion portion 26 and can be inserted into the mounting portion 22 provided on the lower unit 12. The connecting portion 28 has a holding portion 32 that holds the upper unit 14 between the insertion portion 26 and the connecting portion 28 (see Figs. 8 and 9). In the embodiment, the support 18 has the sections 26, 28, 30, and 32 formed by bending a flat plate made of metal or the like.

[0015] As shown in Fig. 12, the hook portion 30 may be omitted and the attachment may be installed by simply inserting the insertion portion 26 between the lower unit 12 and the upper unit 14, as in the case of the support member 38 of the table-type attachment 36. Also, the holding portion 32 provided on the connecting portion 28 may be omitted.

[0016] As an example of assembling the furniture 10 of the embodiment, the hooking part 30 is inserted into the mounting part 22, the inserting part 26 is placed on the upper surface of the lower unit 12, and the attachment 16 is placed on the lower unit 12 (see Fig. 10, Fig. 11(a) and (b)). At this time, the hooking part 30 is restricted from moving in the front-rear direction by the front and rear walls 24, 24 of the mounting part 22, but since it can move in the left-right direction along the groove of the mounting part 22, the left-right position of the attachment 16 can be easily adjusted (see Fig. 10(b) and (c)). Next, the upper unit 14 is inserted between the inserting part 26 and the holding part 32 of the attachment 16, and the upper unit 14 is placed on the lower unit 12 (see Fig. 11(c)). As a result, the upper unit 14 is placed on the lower unit 12, and the furniture 10 in which the attachment 16 is placed on the upper unit 14 is obtained (see Fig. 11(d)).

[0017] In the furniture 10, the insertion portion 26 connected to the attachment 16 via a connecting portion 28 is disposed between the lower unit 12 and the upper unit 14, which are stacked vertically, and the attachment 16 is disposed on the upper unit 14. In this way, the furniture 10 does not need to provide a hole or groove that opens on the seat surface (top surface) of the upper unit 14 because the insertion portion 26 of the support body 18 that supports the attachment 16 is disposed. Therefore, since the furniture 10 does not have a hole or groove for the attachment 16 on the seat surface of the upper unit 14, the appearance of the upper unit 14, which is a relatively conspicuous part of the furniture 10, can be improved. In addition, unlike a configuration in which the seat surface of the upper unit 14 has a hole or groove for the attachment 16, the furniture 10 does not allow small items or dust to get into the holes, etc., and is easy to use. Furthermore, the furniture 10 can avoid placing members on the upper unit 14 that would impede the function of the upper unit 14, such as plywood for supporting the attachments 16, so the upper unit 14 can properly function, such as being more comfortable to sit on.

[0018] In the furniture 10, even when the upper unit 14 is placed on the insertion portion 26, the insertion portion 26 can be moved along the top surface of the lower unit 12, so the position of the attachment 16 can be easily adjusted. In this way, the furniture 10 can be freely rearranged to suit the user's preference by adjusting the attachment 16, for example, to the right or left.

[0019] The support 18 has a hook portion 30 that extends in a direction intersecting with the insertion portion 26 and hooks onto the lower unit 12. The hooking of the lower unit 12 and the hook portion 30 can prevent the insertion portion 26 from slipping out from between the lower unit 12 and the upper unit 14, and can limit unintended movement of the attachment 16. Since the lower unit 12 has a groove-shaped mounting portion 22 into which the hook portion 30 can be inserted, the hooking of the hook portion 30 and the mounting portion 22 can limit unintended movement of the attachment 16. In the embodiment, the hook portion 30 hooks onto the rear wall 24 of the mounting portion 22, restricting rearward movement of the attachment 16 and appropriately supporting the back of the user leaning against the attachment 16. Furthermore, even if a force is applied that rotates the attachment 16 backward with the bottom of the attachment 16 as a fulcrum, the hook portion 30 hooks onto the front wall 24 of the mounting portion 22, thereby restricting the rotation of the attachment 16 and making it possible to appropriately support the load on the attachment 16. Then, by moving the hook portion 30 along the groove of the mounting portion 22, the movement of the attachment 16 can be stabilized.

[0020] The support body 18 has a holding portion 32 that holds the upper unit 14 between itself and the insertion portion 26, which can prevent the upper unit 14 from shifting out of position. The support body 18 has a connecting portion 28 that rises from the insertion portion 26, so that the upper unit 14 can be positioned by contacting the connecting portion 28 with the upper unit 14.

[0021] For the attachment 16 placed at the rear of the upper unit 14, by providing the mounting portion 22 forward of the center in the front-to-rear direction of the lower unit 12, the insertion portion 26 can be made longer to stabilize the attachment 16. Also, even if the insertion portion 26 is inserted between the lower unit 12 and the upper unit 14 from the front and the hook portion 30 is inserted into the mounting portion 22, the attachment 16 can be placed at the front of the upper unit 14. In this case, the attachment 16 is placed so that it protrudes forward, making it possible to widen the seating surface of the upper unit 14.

[0022] (Example of change) The present invention is not limited to the above, and may be, for example, as follows: It should be noted that the present invention is not limited to the specific descriptions of the examples and the following modified examples. (1) In the above embodiment, a sofa is given as an example of rearrangeable furniture, but the present invention is not limited to this and may be, for example, a bed or other furniture. (2) The front, rear, left and right in the embodiments are designated for convenience, and the attachment may be disposed in any position on the upper unit, front, rear, left or right. (3) The attachment may be positioned by, for example, hooking the support to the peripheral surface, such as the front surface, of the lower unit, or to the bottom surface of the lower unit. (4) The mounting portion is not limited to a configuration in which it opens on the top surface of the lower unit, but may open on a peripheral surface such as the front surface of the lower unit or on the bottom surface of the lower unit. If the mounting portion opens on the peripheral surface of the lower unit, it is preferable that the upper unit cover the peripheral surface where the mounting portion opens.
