Mode for Carrying Out the Invention

[0009] Next, with respect to the configurable furniture according to the present invention, a preferred embodiment will be described below with reference to the accompanying drawings. In the following description, a sofa is exemplified as the configurable furniture.

Embodiment

[0010] As shown in FIGS. 1 to 9, the configurable furniture (hereinafter simply referred to as furniture) 10 according to the embodiment includes 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 includes a support 18 that supports the attachment 16. The attachment 16 of the embodiment is supported by two supports 18, 18 provided at a distance from each other in the left-right direction.

[0011] The lower unit 12 of the embodiment is configured by covering a frame such as wood with an exterior material such as cloth (see FIG. 8) and has a rectangular shape in 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 attachment portion 22 into which the support 18 can be inserted. The attachment portion 22 opens on the upper surface of the lower unit 12 and extends in the left-right direction. Further, the attachment portion 22 is preferably provided on the front side of the lower unit 12 rather than at the center in the front-rear direction (see FIG. 8). As shown in FIGS. 10 and 11, the attachment portion 22 may be provided on the front side of the lower unit 12 rather than at the center in the front-rear direction, or may be at the center. The front and rear walls 24 that face each other and constitute the attachment portion 22 are made of a material having rigidity such as wood.

[0012] The upper unit 14 of the embodiment constitutes the seating surface (the designed surface of the furniture) on which the user sits in the furniture 10, and a cushion softer than the lower unit 12 may be used. The upper unit 14 is rectangular in plan view and as long as the lower unit 12 in the same left - right direction (see FIG. 3). As shown in FIGS. 1 to 3, the upper unit 14 is arranged so as to overlap the upper side of the attachment portion 22 provided on the lower unit 12, and the attachment portion 22 is hidden by the upper unit 14. In the embodiment, the upper unit 14 is arranged to overlap the lower unit 12 so as to cover the entire upper surface of the lower unit 12. Note that the upper unit 14 may be fixed in place with a surface fastener provided between the lower unit 12 and the upper unit 14. Here, when providing a surface fastener, it is desirable to arrange it outside the position through which the insertion portion 26 (described later) of the support 18 passes.

[0013] The attachment 16 is a member that provides a predetermined function to the user of the furniture 10. The attachment 16 of the embodiment is a backrest (see FIGS. 1 to 3). The attachment 16 of the embodiment is arranged on the rear side of the upper surface of the upper unit 14 (see FIG. 3). For example, like the table - type attachment 36 shown in FIG. 12, those having a function different from the backrest or different types having the same function as the attachment 16 of the embodiment but different backrest heights may be additionally installed or installed in place of the attachment 16. In the furniture 10, not only one attachment 16 can be installed, but also a plurality of attachments 16, 36 can be installed (see FIG. 12). In this way, the furniture 10 can install various types and numbers of attachments 16, 36 and can easily provide usage methods 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 that connects the insertion portion 26 and the attachment 16. The connecting portion 28 extends in a direction (vertical direction) intersecting the horizontally extending insertion portion 26, rises along the peripheral wall surface of the upper unit 14, and leads to the attachment 16. The support 18 has a latching portion 30 that extends in a direction intersecting the insertion portion 26 and catches on the lower unit 12 (see FIG. 8). The latching 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 sandwiches the upper unit 14 between it and the insertion portion 26 (see FIGS. 8 and 9). The support 18 of the embodiment is formed by bending a flat plate such as metal to form the respective portions 26, 28, 30, 32.

[0015] Similar to the support 38 of the table-type attachment 36 shown in FIG. 12, the latching portion 30 may be omitted, and the attachment may be installed simply by inserting the insertion portion 26 between the lower unit 12 and the upper unit 14. 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 latching portion 30 is inserted into the mounting portion 22, the insertion portion 26 is placed on the upper surface of the lower unit 12, and the attachment 16 is disposed on the lower unit 12 (see FIGS. 10, 11(a) and (b)). At this time, the latching portion 30 is restricted from moving in the front-rear direction by the front and rear walls 24, 24 of the mounting portion 22, but can move in the left-right direction along the groove of the mounting portion 22, so the left-right position of the attachment 16 can be easily adjusted (see FIGS. 10(b) and (c)). Next, the upper unit 14 is inserted between the insertion portion 26 and the holding portion 32 of the attachment 16, and the upper unit 14 is placed on the lower unit 12 (see FIG. 11(c)). Thereby, the upper unit 14 is disposed on the lower unit 12, and the furniture 10 with the attachment 16 disposed on the upper unit 14 is formed (see FIG. 11(d)).

[0017] Furniture 10 has an insertion part 26 that is connected to the attachment 16 via a connecting part 28 and is arranged between a lower unit 12 and an upper unit 14 that overlap vertically, with the attachment 16 arranged on top of the upper unit 14. In this way, since furniture 10 arranges the insertion part 26 of the support 18 that supports the attachment 16, there is no need to provide holes, grooves, etc. that open in the seating surface (upper surface) of the upper unit 14. Therefore, since there are no holes, grooves, etc. for the attachment 16 in the seating surface of the upper unit 14, the appearance of the upper unit 14, which is a relatively noticeable part in the furniture 10, can be improved. Also, unlike a configuration where there are holes, grooves, etc. for the attachment 16 in the seating surface of the upper unit 14, small items and dust do not enter the holes, etc., improving usability. Furthermore, since furniture 10 can avoid arranging a member that obstructs the function of the upper unit 14, such as a plywood board, for supporting the attachment 16 in the upper unit 14, the sitting comfort of the upper unit 14 can be improved, and the function of the upper unit 14 can be appropriately exerted.

[0018] Even when the upper unit 14 is placed on top of the insertion part 26, the furniture 10 can move the insertion part 26 along the upper surface of the lower unit 12, so the position of the attachment 16 can be easily adjusted. In this way, the furniture 10 can adjust the attachment 16, for example, to the right or left and freely rearrange it according to the user's preference.

[0019] The support body 18 extends in a direction intersecting the insertion part 26 and has a latching part 30 that catches on the lower unit 12. Due to the engagement between the lower unit 12 and the latching part 30, it is possible to prevent the insertion part 26 from coming out from between the lower unit 12 and the upper unit 14, and it is possible to restrict the unintended movement of the attachment 16. Since the lower unit 12 has a groove-shaped attachment part 22 into which the latching part 30 can be inserted, the engagement between the latching part 30 and the attachment part 22 can restrict the unintended movement of the attachment 16. In the case of an embodiment, when the latching part 30 catches on the rear wall 24 in the attachment part 22, the rearward movement of the attachment 16 is restricted, and the back of the user leaning on the attachment 16 can be appropriately supported. Also, even when a force is applied to rotate the attachment 16 backward with the bottom of the attachment 16 as a fulcrum, the rotation of the attachment 16 is restricted when the latching part 30 catches on the front wall 24 in the attachment part 22, and the load applied to the attachment 16 can be appropriately supported. And by moving the latching part 30 along the groove of the attachment part 22, the movement of the attachment 16 can be stabilized.

[0020] Since the support body 18 has a holding part 32 that sandwiches the upper unit 14 between it and the insertion part 26, the displacement of the upper unit 14 can be suppressed. Since the support body 18 has a connecting part 28 that rises from the insertion part 26, the upper unit 14 can be positioned by placing the upper unit 14 against the connecting part 28.

[0021] For the attachment 16 arranged at the rear part of the upper unit 14, by providing the attachment part 22 on the front side of the center in the front-rear direction of the lower unit 12, the insertion part 26 can be lengthened and the attachment 16 can be stabilized. Also, even when the insertion part 26 is inserted from the front side between the lower unit 12 and the upper unit 14 and the latching part 30 is inserted into the attachment part 22, the attachment 16 can be arranged at the front part of the upper unit 14. At this time, the attachment 16 can be arranged to protrude forward, and the seating surface of the upper unit 14 can be widened.

[0022] (Modification example) Not limited to the above-described matters, for example, the following may be used. Note that the present invention is not limited to the specific descriptions of the embodiments and the following modification examples. (1) In the embodiment, a sofa is cited as the reconfigurable furniture, but it is not limited thereto, and for example, a bed or other furniture may be used. (2) The front, rear, left, and right in the embodiment are referred to for convenience, and the attachment may be arranged at any position in the front, rear, left, and right on the upper unit. (3) The positioning of the attachment may be performed by, for example, hooking the support on the peripheral surface such as the front surface of the lower unit or hooking it on the bottom surface of the lower unit. (4) The attachment portion is not limited to the configuration that opens on the upper surface of the lower unit, and for example, it may open on the peripheral surface such as the front surface of the lower unit or on the bottom surface of the lower unit. When the attachment portion opens on the peripheral surface of the lower unit, it is desirable to cover the peripheral surface where the attachment portion opens with the upper unit.
