[0107] according to Figures 1 to 69 The accompanying drawings illustrate the support components involved in this utility model.

[0108] like Figures 1 to 16 As shown, the support member 20 in the first embodiment is used to support the base plate 3 of the rotatable headrest 2 and the base plate 5 of the rotatable armrest 4 provided on the sofa 1.

[0109] like Figure 1 as well as Figure 2 As shown, the support member 20 of this utility model is screwed into and embedded in the mounting hole 7 provided on the base material 6 of the sofa 1, and supports the support shaft 11 of the angle adjustment accessory 10. The angle adjustment accessory 10 supports the base plate 3 of the headrest 2 and the base plate 5 of the armrest 4 in a manner that allows them to rotate. It should be noted that the mounting hole 7 can be a bottomed hole or a through hole.

[0110] like Figures 3 to 6 As shown, the support member 20 consists of an annular flange portion 21 and a cylindrical body 30. The annular flange portion 21 is covered by a cover 22 of the same shape. It should be noted that the cover 22 can be installed as needed and is not an essential component.

[0111] like Figure 5 As shown, the aforementioned cylindrical body 30 can be divided into two parts along the axial direction, consisting of a main body 31 integral with the annular flange 21 and a segment 32 that can be separated from the annular flange 21. Furthermore, a semi-circular rib 33 located at the upper end of the segment 32 is engaged with the inner edge of the annular flange 21, and then the segment 32 is pressed against the main body 31. Thus, as... Figure 6 As shown, the mounting portion 35 of the dividing portion 32 is elastically engaged with the locking protrusion 34 of the main body portion 31, and the main body portion 31 and the dividing portion 32 are integrated.

[0112] It should be noted that although the above-mentioned cylindrical body 30 has a bottom surface, it is not necessary to have a bottom surface, and it can of course be formed into a through structure.

[0113] like Figures 7 to 12 As shown, a spiral-shaped protrusion serving as a mounting mechanism 36 is formed on the outer peripheral surface of the upper half of the cylindrical body 30. In the main body 31 and the dividing section 32, downward-facing elastic pieces 38 are formed through "コ"-shaped slits 37 located in their respective lower halves. A locking claw 39 protrudes from the lower edge of the inner peripheral surface of the elastic piece 38, engaging with the annular groove 12 of the support shaft 11 (described later) and preventing it from falling off (see [link]). Figure 6 ).

[0114] It should be noted that the locking claw 39 does not need to be a single ridge; it can also be one or more protrusions.

[0115] Alternatively, the mounting mechanism 36 and the elastic plate 38 can be configured by reversing their vertical positions.

[0116] As an example, regarding the method of using the support member 20 involved in this embodiment, such as... Figure 1 as well as Figure 2 As shown, it is used in the case of the angle adjustment accessory 10 that adjusts the angle of the base plate 3 supporting the headrest 2.

[0117] More specifically, the support member 20 is fixed to the mounting hole 7 by screwing it into and embedding it in the mounting hole 7 provided on the base material 6 of the sofa 1. Then, as... Figure 13 as well as Figure 14 As shown, when the support shaft 11 of the angle adjustment accessory 10 is inserted into the cylindrical body 30 of the support member 20, the elastic plate 38 is pushed outward. Furthermore, by pressing in the support shaft 11, as... Figure 15 as well as Figure 16 As shown, the locking claw 39 of the elastic piece 38 is locked to the annular groove 12 provided on the outer peripheral surface of the support shaft 11, thereby preventing the support shaft 11 of the angle adjustment accessory 10 from falling off and supporting the angle adjustment accessory 10.

[0118] It should be noted that the substrate 6 is not limited to wood, but can also be other materials, such as metal or synthetic resin.

[0119] like Figures 17 to 20 As shown, in the second embodiment, the support member 20 forms an upward elastic sheet 38 through a "ko"-shaped slit 37 provided in the lower half of the cylindrical body 30. A locking claw (not shown) protrudes from the upper edge of the inner circumferential surface of the elastic sheet 38 and can engage with the annular groove 12 of the support shaft 11.

[0120] Note that, as with the first embodiment described above, the cylindrical body 30 can of course be configured to be separable into the main body portion and the divided portion.

[0121] Since the other structures are the same as those of the above-described embodiments, the same symbols are assigned to the same parts and the description thereof is omitted.

[0122] As shown in FIG. 6, the support 20 according to the third embodiment is configured such that the elastic piece 38 is formed by providing the slit 37 in the "コ" shape in the lower half portion of the cylindrical body 30. A locking claw portion (not shown) capable of being locked to the annular groove portion 12 of the support shaft 11 is provided protruding from the inner peripheral surface of the elastic piece 38, for example, the upper end edge portion, the lower end edge portion, or the free end portion.
