[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-173224 Summary of the Invention [Problem to be solved by the invention]

[0004] In the fixture described in Patent Document 1, the shape of the pressure plate must correspond to the leg, so it is necessary to prepare a variety of fixtures with pressure plates of different shapes so that a pressure plate corresponding to the shape of the leg can be selected. There has been a demand for an improvement in the fixture so that the same fixture can be used for legs of different shapes. [Means for solving the problem]

[0005] The fixing body that solves the above problem is a fixing body that fixes the legs of furniture to an installation surface, and is equipped with a fixing part that is fixed to the fixed surface and a holding part that holds the legs, and the holding part consists of a support part that stands upright in the erection direction and has an L-shaped cross section perpendicular to the erection direction, and a winding body that winds the legs that are abutted against the inner surface of the support part together with the support part.

[0006] In the fixed body, the support portion may be provided with a displacement prevention portion that protrudes from the support portion toward an outside of the support portion and prevents the wound body from being displaced in the erecting direction. In the fixed body, the wound body is in the shape of a strip that is wound so that one of two opposing surfaces abuts the support portion and the leg portion, a through hole is formed that passes through the two surfaces, and a protrusion is formed on the support portion that catches the wound body when inserted into the through hole.

[0007] The fixed body may have a support plate having an upper surface formed with a support surface on which the leg portion is placed and a lower surface formed with the fixing portion, and the support portion may be erected from the support plate. The fixing structure that solves the above problem is characterized in that the fixing body described above is fixed to the fixed surface, the leg portion is arranged inside the support portion, and the wound body winds the leg portion together with the support portion in a state in which the inner surface of the support portion abuts the leg portion at least at two points separated from each other around the outer circumference of the leg portion, and the wound body is in close contact with the outer surface of the support portion. [Effects of the Invention]

[0008] According to this invention, the legs can be fixed to the installation surface with their postures stabilized, regardless of the shape of the legs. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a perspective view showing furniture, legs, and a fixed body according to an embodiment. FIG. [Figure 2] FIG. [Figure 3] FIG. [Figure 4] FIG. [Figure 5] FIG. 3 is a cross-sectional view showing the legs and the fixed body. [Figure 6] FIG. [Figure 7] FIG. [Figure 8] FIG. [Figure 9] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the fixing body and fixing structure will be described below with reference to the drawings. For convenience of explanation, the following will describe furniture that is fixed using the fixing body before describing the fixing body and fixing structure.

[0011] <Furniture> As shown in FIG. 1, furniture 10 is placed on an installation surface F. Furniture 10 is fixed to installation surface F by a fixing body 20. Installation surface F is, for example, a floor surface. Installation surface F is a horizontal plane. A direction perpendicular to installation surface F is also referred to as the up-down direction X. Up-down direction X is also the direction of gravity. An example of furniture 10 is a sofa. Furniture 10 has a sofa body 11 and four legs 12. FIG. 1 illustrates two of the four legs 12. Sofa body 11 has, for example, a seat 11a on which a person can sit and a backrest 11b against which a person sitting on seat 11a can lean. Each leg 12 is fixed to a bottom 11c of sofa body 11. In this embodiment, each leg 12 is cylindrical. Each leg 12 extends from the bottom 11c of the sofa body 11 so that the axis of each leg 12 extends in the vertical direction X.

[0012] <Fixed body> The fixed body 20 has a support plate 21 and a holder 30 that holds the leg 12. One fixed body 20 is attached to each of the four legs 12 of the furniture 10. The fixed body 20 fixes the legs 12 of the furniture 10 to the installation surface F.

[0013] <Support plate> 2 and 3, the support plate 21 is made of metal and has a rectangular flat plate shape. The support plate 21 has a pair of first edges 21c extending in a first direction Y and a pair of second edges 21d extending in a second direction Z. The first direction Y and the second direction Z are perpendicular to each other. The first direction Y and the second direction Z are directions along the installation surface F and perpendicular to the up-down direction X. The support plate 21 has an upper surface 21a and a lower surface 21b perpendicular to the up-down direction X.

[0014] As shown in FIG. 2, the upper surface 21a of the support plate 21 functions as a support surface 22 on which the leg 12 is placed. That is, the support surface 22 is formed on the upper surface 21a of the support plate 21. The size of the support surface 22 relative to the upper surface 21a of the support plate 21 is the size of the lower end surfaces of the legs 12 placed on the support surface 22. The lower end surfaces of the legs 12 in this embodiment are circular and smaller than the upper surface 21a of the support plate 21. Therefore, a portion of the upper surface 21a of the support plate 21 functions as the support surface 22. The entire lower end surfaces of the legs 12 are placed on the support surface 22. In this embodiment, all of the legs 12 of the furniture 10 have the same shape.

[0015] As shown in FIG. 3 , an adhesive member for adhering the fixed body 20 to the installation surface F may be provided on the lower surface 21b of the support plate 21. An example of the adhesive member is an adhesive mat 15. The adhesive mat 15 is, for example, a rectangular flat plate that is slightly smaller than the support plate 21. The adhesive mat 15 may have adhesive surfaces 15a on both sides in the plate thickness direction. One adhesive surface 15a is attached to the lower surface 21b of the support plate 21, and the other adhesive surface 15a is attached to the installation surface F.

[0016] When the adhesive mat 15 provided on the lower surface 21b of the support plate 21 is attached to the installation surface F, the lower surface 21b of the support plate 21 functions as a fixing portion 23 that is fixed to the installation surface F, which is the fixed surface. That is, the fixing portion 23 is formed on the lower surface 21b of the support plate 21. In other words, the fixing body 20 is provided with the fixing portion 23.

[0017] <Holding part> 4, the holding section 30 is made up of a support section 40 and a wound body 31. The holding section 30 is located above the support plate 21.

[0018] <Wound body> The wound body 31 has a strip-like shape. The wound body 31 is formed, for example, from thick cloth, leather, or flexible resin. The wound body 31 has a pair of long edges 31c and a pair of short edges 31d. The pair of long edges 31c are parallel to each other. The pair of short edges 31d are parallel to each other. The extending direction of the long edges 31c is also referred to as the longitudinal direction of the wound body 31. The extending direction of the short edges 31d is also referred to as the lateral direction of the wound body 31. The wound body 31 has an elastic restoring force that causes it to stretch and return to its original shape when pulled in the longitudinal direction of the wound body 31. The longitudinal dimension of the wound body 31 is the dimension of the excess length of the wound body 31 when the wound body 31 is wound once around the leg portion 12 so that the circumferential direction of the leg portion 12 and the longitudinal direction of the wound body 31 are parallel to each other. With the fixed body 20 fixed to the installation surface F, the widthwise direction of the wound body 31 is parallel to the vertical direction X. The dimension of the widthwise direction of the wound body 31 is smaller than the dimension of the leg portion 12 in the vertical direction X.

[0019] The wound body 31 has two opposing surfaces, a first surface 31a and a second surface 31b. The first surface 31a and the second surface 31b are surfaces that face each other in the thickness direction of the wound body 31. A through hole 31h is formed in the wound body 31. The through hole 31h penetrates the first surface 31a and the second surface 31b of the wound body 31. In this embodiment, a plurality of through holes 31h are formed in the wound body 31. The plurality of through holes 31h are positioned apart from each other in the direction in which the long edge portion 31c of the wound body 31 extends. Each through hole 31h may be formed at a middle position of the wound body 31 in the direction in which the short edge portion 31d extends. Note that in FIGS. 3 and 5, some of the plurality of through holes 31h are illustrated, and the other through holes 31h are not illustrated.

[0020] 5, the wound body 31 is wound around the leg portion 12 together with the support portion 40. The wound body 31 is wound so that a first surface 31a, which is one of two opposing surfaces, abuts against the support portion 40 and the leg portion 12. In the portion of the wound body 31 wound around the leg portion 12, the longitudinal direction of the wound body 31 is parallel to the circumferential direction of the leg portion 12.

[0021] <Support part> As shown in FIG. 6, the support part 40 stands upright from the support plate 21. The support part 40 stands upright in a standing direction D and has an L-shaped cross section perpendicular to the standing direction D. In this embodiment, the standing direction D is parallel to the vertical direction X and extends from bottom to top. The support plate 21 and the support part 40 are integrally formed. The support part 40 is made up of a first support part 41 and a second support part 42. The support plate 21, the first support part 41, and the second support part 42 may be integrally formed by bending a metal flat plate material.

[0022] The first support portion 41 extends upward from one of a pair of first edge portions 21c of the support plate 21. The second support portion 42 extends upward from one of a pair of second edge portions 21d of the support plate 21. The first support portion 41 and the second support portion 42 are positioned to face each other across one corner of the upper surface 21a of the support plate 21.

[0023] The second support portion 42 has a second main body portion 43 and a second protrusion portion 44. The second main body portion 43 is a flat plate that stands upward from the second edge portion 21d of the support plate 21. The second main body portion 43 has a second inner surface 43a located on one side in the thickness direction of the second main body portion 43, and a second outer surface 43b located on the other side in the thickness direction of the second main body portion 43. The second inner surface 43a and the second outer surface 43b are flat surfaces that extend perpendicular to the first direction Y.

[0024] The second main body portion 43 has a first end 43c located at one end of the second main body portion 43 in the second direction Z, and a second end 43d located at the other end of the second main body portion 43 in the second direction Z. The first end 43c of the second main body portion 43 extends upward in a straight line from the second edge portion 21d of the support plate 21. The second end 43d of the second main body portion 43 extends upward while curving from the second edge portion 21d of the support plate 21.

[0025] 7, the second protrusion 44 has a rectangular flat plate shape extending in the first direction Y from the upper end 43e of the second main body portion 43 so as to move away from the support plate 21. In other words, the second protrusion 44 protrudes from the support portion 40 toward the outside of the support portion 40. The second protrusion 44 is provided on the support portion 40.

[0026] 6, the first support portion 41 has a first main body portion 33 and a first protrusion portion 34. The first main body portion 33 is a flat plate extending upward from the first edge portion 21c of the support plate 21. The first main body portion 33 has a first inner surface 33a located on one side in the thickness direction of the first main body portion 33, and a first outer surface 33b located on the other side in the thickness direction of the first main body portion 33. The first inner surface 33a and the first outer surface 33b are flat surfaces extending perpendicular to the second direction Z.

[0027] The first main body portion 33 has a first end 33c located at one end of the first main body portion 33 in the first direction Y, and a second end 33d located at the other end of the first main body portion 33 in the first direction Y. The first end 33c of the first main body portion 33 extends while curving upward from the first edge portion 21c of the support plate 21.

[0028] The first protrusion 34 has a rectangular flat plate shape extending in the second direction Z from the upper end 33e of the first main body portion 33 so as to move away from the support plate 21. In other words, the first protrusion 34 protrudes from the support portion 40 toward the outside of the support portion 40. The first protrusion 34 is provided on the support portion 40.

[0029] A cutout 36 is formed in the first main body 33. The cutout 36 is formed in a part of the first main body 33, and is formed by cutting out a part of the first main body 33 from the first end 33c. The cutout 36 is formed in the first main body 33 at a position closer to the first protrusion 34 than the support plate 21 in the up-down direction X.

[0030] A protrusion 35 is formed on the first support portion 41. In other words, the support portion 40 has the protrusion 35 formed thereon. The protrusion 35 extends from the first main body portion 33. The protrusion 35 protrudes from the inside of the cutout portion 36 toward the outside of the support portion 40. The protrusion 35 is positioned so as to be sandwiched by the first main body portion 33 on both sides in the up-down direction X.

[0031] The protrusion 35 has a first protrusion 35a and a second protrusion 35b. The first protrusion 35a extends in the second direction Z from the first main body 33 so as to move away from the support plate 21. The second protrusion 35b extends in the first direction Y from the end of the first protrusion 35a opposite to the end connected to the first main body 33.

[0032] As shown in FIG. 7 , the first support portion 41 has an extension portion 37. The extension portion 37 is a rectangular flat plate. The extension portion 37 extends in the second direction Z from the second end 33d of the first main body portion 33. The first main body portion 33 and the extension portion 37 are integral, and the first main body portion 33 and the extension portion 37 extend in different directions by bending a single plate so that a cross section perpendicular to the erection direction D is L-shaped. The extension portion 37 has an inner surface 37a located on one side of the thickness direction of the extension portion 37 and an outer surface 37b located on the other side of the thickness direction of the extension portion 37. The inner surface 37a and the outer surface 37b are flat surfaces extending perpendicular to the first direction Y.

[0033] 8, the inner surface 37a of the extension portion 37 extends along the second outer side surface 43b of the second main body portion 43. The inner surface 37a and the second outer side surface 43b are welded together, thereby connecting the extension portion 37 and the second main body portion 43.

[0034] The extension portion 37 is located below the second protruding portion 44 of the second support portion 42. The thickness dimension of the extension portion 37 is smaller than the dimension of the second protruding portion 44 in the first direction Y. Therefore, a portion of the second protruding portion 44 protrudes further outward from the support portion 40 than the extension portion 37.

[0035] The inner surface of the support part 40 is made up of the first inner surface 33a of the first main body part 33 and the second inner surface 43a of the second main body part 43. The outer surface of the support part 40 is made up of the first outer surface 33b of the first main body part 33, the second outer surface 43b of the second main body part 43, and the outer surface 37b of the extension part 37.

[0036] <Attachment of the wound body to the support part> 2 and 4, the protrusion 35 of the support portion 40 is inserted into the through hole 31h of the wound body 31, so that the wound body 31 is caught on the protrusion 35. Specifically, the first protrusion portion 35a of the protrusion 35 is inserted into the through hole 31h. The second protrusion portion 35b of the protrusion 35 is located outside the through hole 31h.

[0037] In this embodiment, of the multiple through holes 31h in the wound body 31, protrusions 35 are inserted into two through holes 31h: the through hole 31h closest to one of the pair of short edge portions 31d and the through hole 31h closest to the other of the pair of short edge portions 31d. With the protrusion 35 inserted into one of the two through holes 31h, the wound body 31 is wound around the leg portion 12, and then the protrusion 35 is inserted into the other through hole 31h. Portions of the wound body 31 around the two through holes 31h into which the protrusions 35 are inserted overlap each other in the thickness direction of the wound body 31. In this embodiment, both ends of the wound body 31 in the longitudinal direction of the wound body 31 overlap each other. The dimension of the first protrusion 35a in the second direction Z is greater than the dimension of the double-layered wound body 31 in the thickness direction. Therefore, the second protrusion 35b is located outside the support part 40 relative to the double-layered wound body 31.

[0038] 5, the wound body 31 is wound around the support portion 40, with the leg portion 12 abutting against a first inner surface 33a and a second inner surface 43a, which serve as inner surfaces of the support portion 40. In the portion of the wound body 31 wound around the leg portion 12, the first surface 31a of the wound body 31 abuts against the outer peripheral surface of the leg portion 12, and the longitudinal direction of the wound body 31 coincides with the circumferential direction of the leg portion 12. In the portion of the wound body 31 wound around the support portion 40, the first surface 31a of the wound body 31 abuts against a first outer surface 33b and an outer surface 37b, which serve as outer surfaces of the support portion 40. The portion of the wound body 31 wound around the support portion 40 extends along the first main body portion 33 and the extension portion 37.

[0039] 9, the wound body 31 is located below the first protruding portion 34 and the second protruding portion 44 of the support portion 40. The first protruding portion 34 and the second protruding portion 44 prevent the wound body 31 from being displaced in the erection direction D. Therefore, the first protruding portion 34 and the second protruding portion 44 function as a displacement prevention portion that prevents the wound body 31 from being displaced in the erection direction D.

[0040] While hooked on the protrusion 35, one of the pair of long edges 31c of the wound body 31 is adjacent to the first protrusion 34 and the second protrusion 44. Even if the legs 12 of the furniture 10 move upward due to earthquake shaking, causing the wound body 31 to displace toward the first protrusion 34 and the second protrusion 44, the wound body 31 immediately abuts against the first protrusion 34 and the second protrusion 44. Therefore, a load is unlikely to be applied from the protrusion 35 to the wound body 31 around the through hole 31h, and deformation of the through hole 31h is unlikely to occur. This prevents the wound body 31 from coming off the protrusion 35 due to deformation of the through hole 31h.

[0041] <Fixed structure> As shown in FIGS. 1 and 2, the fixed bodies 20 are fixed to an installation surface F, which is a surface to be fixed to. Four fixed bodies 20 are fixed to the installation surface F. Each of the four fixed bodies 20 is attached to the installation surface F with an adhesive mat 15. The legs 12 of the furniture 10 are placed on the upper surface 21a of the support plate 21. The legs 12 are arranged inside the support parts 40. When fixing the fixed bodies 20 to the installation surface F, the positions of the support parts 40 may be adjusted in the circumferential direction of the legs 12 so that the support parts 40 are less noticeable. In this case, the positions of the support parts 40 relative to the legs 12 may be different for each leg 12.

[0042] 5, the leg portion 12 abuts against the first inner surface 33a of the first main body portion 33 and the second inner surface 43a of the second main body portion 43. This causes the leg portion 12 to abut against the inner surface of the support portion 40. A position P1 of the leg portion 12 at which the leg portion abuts against the first inner surface 33a and a position P2 at which the leg portion abuts against the second inner surface 43a are spaced apart from each other around the outer periphery of the leg portion 12. That is, the inner surface of the support portion 40 abuts against the leg portion 12 at two positions spaced apart from each other around the outer periphery of the leg portion 12. The wound body 31 winds the leg portion 12 together with the support portion 40 in a state in which the first inner surface 33a and the second inner surface 43a as the inner surfaces of the support portion 40 abut against the leg portion 12 at two positions P1 and P2 spaced apart from each other around the outer periphery of the leg portion 12. The wound body 31 winds the leg portion 12 together with the support portion 40 in a state in which the wound body 31 is in close contact with a first outer surface 33b and an outer surface 37b, which serve as outer surfaces of the support portion 40. By wrapping the wound body 31 around the leg portion 12 so as to tighten the leg portion 12, the leg portion 12 is pressed against a first inner surface 33a and a second inner surface 43a, which serve as inner surfaces of the support portion 40.

[0043] [Operation of the embodiment] Next, the operation of this embodiment will be described. The lower surface 21b of the support plate 21, which serves as the fixing portion 23, is fixed to the installation surface F, which serves as the fixed surface, thereby fixing the fixed body 20 to the installation surface F. The fixing body 20 is fixed to the installation surface F with the holding portion 30 holding the leg portion 12, thereby fixing the leg portion 12 to the installation surface F. The holding portion 30 stands in the erection direction D and has a support portion 40 having an L-shaped cross section perpendicular to the erection direction D. The leg portion 12 abuts against a first inner surface 33a and a second inner surface 43a, which serve as inner surfaces of the support portion 40.

[0044] In this embodiment, the leg portion 12 is cylindrical. In this embodiment, the inner surface of the support portion 40 abuts against the leg portion 12 at two positions P1 and P2 that are spaced apart from each other around the outer periphery of the leg portion 12.

[0045] Let us consider a case in which legs 52, 62, each having a different shape from the leg 12 of the present embodiment, are fixed to the installation surface F by the fixture 20. The leg 52 is cylindrical, as shown by the dashed line in FIG. 5 , like the leg 12 of the present embodiment. Furthermore, the cross-sectional area of ​​the leg 52 perpendicular to its axis is smaller than the cross-sectional area of ​​the leg 12 perpendicular to its axis. The leg 52 abuts against the inner surface of the support part 40 at two positions different from the positions P1, P2 at which the leg 12 of the present embodiment abuts. Furthermore, the leg 62 is rectangular prism-shaped, as shown by the dashed line in FIG. 5 . The leg 62 abuts against the inner surface of the support part 40 at two positions over a wider area than the leg 12 of the present embodiment.

[0046] As described above, even for the legs 52, 62 having a shape different from the leg 12 of the embodiment, the inner surface of the support part 40 abuts at two positions spaced apart from each other around the outer periphery of the legs 52, 62. With the leg 12 abutting against the inner surface of the support part 40 in this manner, the leg 12 and the support part 40 are wound by the wound body 31.

[0047] [Effects of the embodiment] According to the above embodiment, the following effects can be obtained. (1) The fixed body 20 includes a fixing portion 23 that is fixed to an installation surface F as a fixed surface, and a holding portion 30 that holds the leg portion 12. The holding portion 30 is made up of a support portion 40 that stands in an erection direction D and has an L-shaped cross section perpendicular to the erection direction D, and a winding body 31 that winds the leg portion 12, which is in contact with the inner surface of the support portion 40, together with the support portion 40. Therefore, regardless of the shape of the leg portion 12, the leg portion 12 can be wound together with the support portion 40 by the winding body 31 in a state in which the leg portion 12 is in contact with two or more points on the inner surface of the support portion 40. Therefore, regardless of the shape of the leg portion 12, the leg portion 12 can be fixed to the installation surface F with the posture of the leg portion 12 stabilized.

[0048] (2) The support portion 40 is provided with the first protrusion 34 and the second protrusion 44 as displacement prevention portions that protrude from the support portion 40 toward the outside of the support portion 40. Therefore, the first protrusion 34 and the second protrusion 44 as displacement prevention portions prevent the wound body 31 from being displaced in the erection direction D, so that the wound body 31 can hold the leg portion 12 to the fixed body 20 more stably.

[0049] (3) The wound body 31 is in the shape of a strip that is wound so that the first surface 31a of the wound body 31 abuts against the support portion 40 and the leg portion 12. The wound body 31 has a through-hole 31h that penetrates the first surface 31a and the second surface 31b of the wound body 31. The support portion 40 has a protrusion 35 that is inserted into the through-hole 31h and onto which the wound body 31 is hooked. Therefore, the wound body 31 can be installed on the support portion 40 by inserting the protrusion 35 into the through-hole 31h of the wound body 31. Therefore, installation of the wound body 31 on the support portion 40 is easier than when installing the wound body 31 on the support portion 40 using an adhesive for bonding the wound body 31 to the support portion 40 or a fixing member for fixing the wound body 31 to the support portion 40.

[0050] (4) The fixed body 20 has a support plate 21 having a top surface 21a on which a placement surface 22 on which the leg 12 is placed and a bottom surface 21b on which a fixing portion 23 is formed. The support portion 40 stands upright from the support plate 21. Therefore, by positioning the fixing portion 23 below the leg 12, the weight of the furniture 10 acts on the fixing portion 23 via the leg 12. Therefore, compared to when the fixing portion 23 is positioned in a position shifted from below the leg 12, the fixing portion 23 can more firmly fix the fixed body 20 to the installation surface F as the surface to be fixed.

[0051] [Example of change] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0052] The means for connecting the extension portion 37 and the second main body portion 43 is not limited to welding. For example, the extension portion 37 may be connected to the second main body portion 43 by fixing the inner surface 37a of the extension portion 37 and the second outer surface 43b of the second main body portion 43 to each other with an adhesive or the like.

[0053] The extension portion 37 may be omitted from the first support portion 41. In this case, the first support portion 41 and the second support portion 42 are fixed to each other by welding, adhesive, or the like. The first outer surface 33b and the second outer surface 43b become the outer surfaces of the support portion 40. The wound body 31 abuts against the first outer surface 33b and the second outer surface 43b.

[0054] The wound body 31 may have one through hole 31h. In this case, the overlapping portions of the first surface 31a and the second surface 31b of the wound body 31 may be adhered to each other, thereby winding the wound body 31 around the leg portion 12 and the support portion 40. The protrusion 35 may be inserted into the through hole 31h at either the start or end of winding the wound body 31 around the leg portion 12 and the support portion 40. This makes it easier to install the wound body 31 on the support portion 40.

[0055] The protrusions 35 may be omitted from the support portion 40. The through holes 31h may be omitted from the wound body 31. The shape of the wound body 31 is not limited to a strip shape. For example, the wound body 31 may be in the shape of a string.

[0056] The first protrusion 34 may extend from a position lower than the upper end 33e of the first main body portion 33. The second protrusion 44 may extend from a position lower than the upper end 43e of the second main body portion 43.

[0057] At least one of the first protrusion 34 and the second protrusion 44 may be omitted from the support portion 40. The shape of the support plate 21 is not limited to a rectangular flat plate. For example, the support plate 21 may be a polygonal flat plate other than a rectangle, or may be a circular flat plate.

[0058] Instead of the adhesive mat 15, an adhesive may be applied to the lower surface 21b of the support plate 21, thereby fixing the lower surface 21b to the installation surface F as the fixing surface. In this case, the support plate 21 also has fixing portions 23 formed on the lower surface 21b.

[0059] The fixing portion 23 may be formed in a part other than the lower surface 21b of the support plate 21. In this case, the fixing portion 23 may be fixed to a fixed surface other than the installation surface F. For example, if the installation surface F is a floor surface, the fixed surface may be a wall surface.

[0060] The support plate 21 may be omitted from the fixed body 20. In this case, the legs 12 may be placed directly on the installation surface F. The legs 12 may be fixed to the installation surface F by attaching the lower end surfaces of the legs 12 to the installation surface F using fixing means such as an adhesive mat 15 or adhesive. In this case, the fixed body 20 includes fixing means for fixing the legs 12. The support part 40 may be erected in the erection direction D from the installation surface F.

[0061] The shape of the leg portion 12 is not limited to a cylindrical shape. For example, the leg portion 12 may be a square prism or a polygonal prism other than a square prism. Of the multiple legs 12 of the furniture 10, some of the legs 12 may have a different shape from the other legs 12.

[0062] The number of legs 12 of the furniture 10 may be three or less, or may be five or more. Of the plurality of legs 12 of the furniture 10, the fixing members 20 provided on some of the legs 12 may have different configurations from those provided on the other legs 12.

[0063] The furniture 10 is not limited to a sofa. The furniture 10 may be a single-seater chair, a desk, a shelf, or the like. The installation surface F to which the fixed body 20 fixes the legs 12 is not limited to the floor. For example, the installation surface F may be a wall.

[0064] Of the multiple legs 12 of the furniture 10, the fixing bodies 20 may be provided on all of the legs 12, or the fixing bodies 20 may be provided on one leg 12 or on some but not all of the legs 12.

[0065] In the fixed body 20 provided on the leg 12 of the furniture 10, the support part 40 is preferably positioned below the furniture 10 across the leg 12. In other words, the support part 40 erected from the edge of the support plate 21 positioned below the leg 12 is preferably positioned at the farthest point from the outside in the space below the furniture 10. This can prevent a person's legs from hitting the support part 40. [Explanation of symbols]
