[0007] The embodiments described below are merely examples of the present disclosure, and the present disclosure is not limited to these embodiments. Various modifications other than these embodiments are possible depending on the design, etc., as long as they do not deviate from the technical concept of the present disclosure.

[0008] [Embodiment 1] A wall hanger 100 according to a first embodiment will be described with reference to FIGS. 1 to 9. FIG. 1 is a plan view illustrating the configuration of the wall hanger 100 according to the first embodiment. FIG. 2 is a perspective view illustrating the configuration of the wall hanger 100 according to the first embodiment. FIG. 3 is an exploded perspective view of the wall hanger 100 according to the first embodiment.

FIG. 6 is a first exploded perspective view of the elongated hole forming portion 20 of the first member 1, the insertion hole forming portion 40 of the second member 2, and the restricting member 3 of the wall hanger 100 according to the first embodiment. FIG. 7 is a second exploded perspective view of the elongated hole forming portion 20 of the first member 1, the insertion hole forming portion 40 of the second member 2, and the restricting member 3 of the wall hanger 100 according to the first embodiment. Fig. 8 is a cross-sectional view of the wall hanger 100 according to embodiment 1, showing the elongated hole forming portion 20 of the first member 1, the insertion hole forming portion 40 of the second member 2, and the vicinity of the restricting member 3. Fig. 9 is a bottom view of the wall hanger 100 according to embodiment 1.

[0009] The wall hanger 100 is used, for example, to hang a display device TV, which is an installation item, on a wall surface Wa of a wall W, which serves as an installation surface. Note that the installation item hung on the wall W using the wall hanger 100 is not limited to a display device TV, and may be an electronic device or component other than a display device.

[0010] As shown in FIGS. 1 to 5 , the wall hanger 100 includes a first member 1, a second member 2, and a restricting member 3. One of the first member 1 and the second member 2 is attached to a wall surface Wa of a wall W, and the other is attached to a display device TV installed on the wall surface Wa. The restricting member 3 restricts rotation of the second member 2 relative to the first member 1. The restricting member 3 may be, for example, a screw, a bolt, or a pair of bolts and nuts, but is not limited to these, and may be any member that can restrict rotation of the second member 2 relative to the first member 1.

[0011] In this embodiment, an example will be described in which, of the first member 1 and the second member 2, the first member 1 is attached to a wall surface Wa (see FIG. 4), and the second member 2 is attached to a rear surface TVa of the display device TV (see FIG. 5). The rear surface TVa of the display device TV is the surface opposite to the surface of the display device TV on which an image is displayed. The first member 1, the second member 2, and the restricting member 3 can each be formed using a metal material, but the material for forming each is not limited to metal. In particular, since the first member 1 is a member for supporting the display device TV to which the second member 2 is attached, it is preferable that it be formed using a metal material from the viewpoint of strength.

[0012] The first member 1 has a protrusion forming portion 10 in which a protrusion 12 is formed, and an elongated hole forming portion 20 in which an elongated hole 22a is formed. The second member 2 has an attachment portion 30 in which an opening 30a into which the protrusion 12 is inserted is formed, and an insertion hole forming portion 40 in which an insertion hole 42a (described later using FIG. 7 etc.) into which the restricting member 3 is inserted is formed.

[0013] The protrusion-forming portion 10 has a support portion 11 in addition to the protrusion portion 12 described above. The support portion 11 is, for example, a rectangular plate-like member, but is not limited to this. As an example, the support portion 11 extends so that the longitudinal direction is in the Y direction. A plurality of through holes 10h are formed on the edge of the support portion 11. The support portion 11 is fixed to the wall surface Wa by inserting a fixing member such as a nail, screw, bolt, or the like into each of the plurality of through holes 10h (see FIG. 4). In other words, the protrusion-forming portion 10 is fixed to the wall surface Wa. Note that the fixing members inserted into the plurality of through holes 10h may be any member capable of fixing the support portion 11 to the wall W.

[0014] The protrusion 12 is formed to protrude from the support portion 11. For example, the protrusion 12 is formed on the support portion 11 so as to protrude from one of the two main surfaces of the support portion 11 opposite the back surface facing the wall surface Wa. The protrusion 12 functions as a hook for hanging the attachment portion 30 of the second member 2. The protrusion 12 has, for example, a shaft portion and a plate-shaped portion 12a having a diameter larger than that of the shaft portion. The base of the shaft portion is connected to the surface of the support portion 11, and the top of the shaft portion is connected to the plate-shaped portion 12a. The shaft portion may be, for example, cylindrical. The plate-shaped portion 12a may be, for example, circular in plan view. Note that the shapes of the shaft portion and the plate-shaped portion 12a are not limited to cylindrical and circular, respectively. Furthermore, the plate-shaped portion 12a, the shaft portion, and the support portion 11 may be fixed to each other by connecting them with fixing members such as screws, bolts, or the like, or may be formed integrally.

[0015] The protrusions 12 protrude, for example, in a direction intersecting the longitudinal direction (e.g., the Y direction) of the protrusion-forming portion 10. In this embodiment, the protrusions 12 are formed on the support portion 11 so as to protrude from the surface of the support portion 11 in the X direction perpendicular to the Y direction. The direction in which the protrusions 12 protrude from the support portion 11 is not limited to the perpendicular direction, and may be, for example, a direction substantially perpendicular to the longitudinal direction of the support portion 11. Furthermore, the protrusion-forming portion 10 is not limited to the above-mentioned shape, etc., as long as the protrusions 12 are formed thereon.

[0016] 1 to 9 , the elongated hole forming portion 20 has a first plate-shaped portion 21 and a first bent portion 22 that is bent from the first plate-shaped portion 21 and has an elongated hole 20a formed therein. For example, in this embodiment, the elongated hole forming portion 20 is a member that is provided away from the protrusion forming portion 10. When the first member 1 is attached to the wall surface Wa, the elongated hole forming portion 20 is attached to the wall surface Wa so as to be positioned vertically below the protrusion forming portion 10.

[0017] In this way, by configuring the first member 1 so that the elongated hole forming portion 20 and the protrusion forming portion 10 are spaced apart, it becomes easier to adjust the distance between the protrusion forming portion 10 and the elongated hole forming portion 20. Therefore, it is possible to easily adjust the distance between the protrusion forming portion 10 and the elongated hole forming portion 20 depending on the size and weight of the display device TV to be installed on the wall surface Wa. Therefore, when installing a display device TV on the wall surface Wa using the wall hanger 100, the range of sizes and weights of display devices TVs that can be installed can be widened, so that the wall hanger 100 can be used for various types of display device TVs and can be made more versatile.

[0018] A plurality of through holes 20h are formed in the first plate-shaped portion 21, for example, on both edges and between the both edges. A fixing member such as a nail, screw, bolt, or the like is inserted into each of the plurality of through holes 20h, thereby fixing the first plate-shaped portion 21 to the wall surface Wa (see FIG. 4). In other words, the slotted hole forming portion 20 is fixed to the wall surface Wa. Note that the fixing members inserted into the plurality of through holes 20h may be any member that can fix the first plate-shaped portion 21 to the wall W.

[0019] The first bent portion 22 bends from the lower end of the first plate-shaped portion 21 in a direction away from the wall surface Wa when the first plate-shaped portion 21 is attached to the wall surface Wa. For example, the first bent portion 22 extends from the lower end of the first plate-shaped portion 21 so that the longitudinal direction is a direction intersecting the direction in which the protrusion 12 of the protrusion-forming portion 10 protrudes (e.g., the X direction). In this embodiment, the first bent portion 22 extends so that the longitudinal direction is the Y direction, which is perpendicular to the X direction in which the protrusion 12 protrudes. In this embodiment, the first bent portion 22 extends linearly. Note that the first bent portion 22 and the first plate-shaped portion 21 may be integrally formed by bending a single plate, or the first plate-shaped portion 21 and the first bent portion 22 may be formed separately and connected and fixed to each other by fixing members such as screws, bolts, or the like.

[0020] At least one elongated hole 20a, which is a through hole, is formed in the first bent portion 22. The elongated hole 20a is formed in the first bent portion 22 so that the longitudinal direction of the elongated hole 20a is a direction intersecting the direction in which the protrusion 12 of the protrusion-forming portion 10 protrudes (e.g., the X direction). For example, the elongated hole 20a is formed so that the longitudinal direction of the elongated hole 20a is a Y direction perpendicular to the X direction in which the protrusion 12 protrudes. When the restricting member 3 is inserted into the elongated hole 20a, which overlaps with an insertion hole 40a (see FIG. 7) formed in the second bent portion 42 (described later), the angle (i.e., attitude) of the second member 2 (i.e., the display device TV to which the second member 2 is attached) relative to the first member 1 (i.e., the wall surface Wa to which the first member 1 is attached) is adjusted within the range of the longitudinal length L (see FIG. 9) of the elongated hole 20a and then fixed.

[0021] Only one elongated hole 20a may be formed in the first bent portion 22, but from the viewpoint of the strength for fixing the angle (i.e., attitude) of the second member 2 relative to the first member 1, it is preferable that a plurality of elongated holes 20a be formed in the first bent portion 22. Then, by inserting the restricting members 3 so as to pass through each of the plurality of elongated holes 20a and through the insertion holes 40a (see FIG. 7 ) that overlap each of the plurality of elongated holes 20a, the first bent portion 22 and the second bent portion 42 are fixed by the plurality of restricting members 3, and the angle (i.e., attitude) of the second member 2 relative to the first member 1 can be fixed more firmly.

[0022] For example, by making the longitudinal direction (e.g., Y direction) of the first bent portion 22 coincide with the longitudinal direction (e.g., Y direction) of the elongated hole 20a, the multiple elongated holes 20a can be formed linearly aligned in their respective longitudinal directions (e.g., Y direction) in the longitudinal direction (e.g., Y direction) of the first bent portion 22. This allows the restricting member 3 to be inserted through the multiple linearly aligned elongated holes 20a and the insertion holes 40a that overlap with each of the multiple elongated holes 20a, thereby more firmly fixing the angle (i.e., attitude) of the second member 2 relative to the first member 1. Note that the longitudinal directions of the first bent portion 22 and the elongated holes 20a are not limited to directions perpendicular to the direction in which the protrusion 12 protrudes (e.g., X direction), and may be directions substantially perpendicular to the direction in which the protrusion 12 protrudes (e.g., X direction).

[0023] In this embodiment, a plurality of elongated holes 20a are formed in the first bent portion 22. The plurality of elongated holes 20a include a plurality of elongated holes 20a1 that are lined up along the Y direction on a side relatively closer to the first plate-shaped portion 21, and a plurality of elongated holes 20a2 that are lined up along the Y direction on a side relatively farther from the first plate-shaped portion 21 than the plurality of elongated holes 20a1.

[0024] The second member 2 is hung on the first member 1 so that either the multiple elongated holes 20a1 or the multiple elongated holes 20a2 overlaps with the multiple insertion holes 40a, depending on the shape of the back surface TVa of the display device TV, etc. Then, multiple regulating members 3 are inserted into the multiple insertion holes 40a and the multiple elongated holes 20a1 or the multiple elongated holes 20a2, which overlap each other, and are screwed together, for example, to regulate the rotation of the second member 2 relative to the first member 1. In other words, the angle of the second member 2 relative to the first member 1 is fixed. Note that the elongated hole forming portion 20 is not limited to the above-mentioned shape, as long as it has at least one elongated hole 20a formed therein.

[0025] As shown in FIGS. 1 to 5, the mounting portion 30 has a main portion 31 with an opening 30a formed therein and edge portions 32 and 33, which are both edges of the main portion 31. The main portion 31 is, for example, a plate-like member having a rectangular outer shape with a notch formed at the bottom, but is not limited thereto. An opening 30a having an area larger than that of the plate-like portion 12a of the protrusion 12 of the protrusion-forming portion 10 is formed in the approximate center of the main portion 31. When the mounting portion 30 is viewed from the normal direction of the main surface (when viewed from above), the upper end of the opening 30a is cut so that it gradually convex upward (in the Z-axis direction (vertically upward) perpendicular to the XY plane when the XY plane is considered to be a horizontal plane) from both ends of the upper end toward the approximate center of the upper end. The top of the opening 30a has a convex shape with a triangular apex angle curved. When the protrusion 12 is inserted into the opening 30a, the curved inner side surface of the top of the opening 30a comes into contact with the outer circumferential surface of the shank (not shown) of the protrusion 12. As a result, the attachment portion 30 is attached to the protrusion-forming portion 10 on which the protrusion 12 is formed so as to be rotatable around the protrusion 12 as the center of rotation. Furthermore, the plate-like portion 12a of the protrusion 12, which is provided on the top of the shank, has a larger diameter than the shank. Therefore, the plate-like portion 12a functions as a stopper that prevents the attachment portion 30 from slipping off the shank of the protrusion 12. Note that the above-described shape of the opening 30a is one example, and any shape may be used as long as it allows the attachment to be rotatable around the protrusion 12 as the center of rotation.

[0026] Each of the edge portions 32 and 33 is formed so as to curve toward the main portion 31 or the display device TV (e.g., the X direction) and contact the rear surface TVa of the display device TV when the mounting portion 30 is mounted on the display device TV. In a plan view, the edge portions 32 and 33 extend, for example, along the end of the main portion 31 so that their longitudinal direction is in a predetermined direction (e.g., the Z axis direction perpendicular to the XY plane). For example, a plurality of through holes 30h are formed in the edge portions 32 and 33. Then, a fixing member such as a nail, screw, bolt, or the like is inserted into each of the plurality of through holes 30h, thereby fixing the mounting portion 30 to the rear surface TVa of the display device TV (see FIG. 5). Note that the fixing member inserted into the plurality of through holes 30h may be any member capable of fixing the mounting portion 30 to the rear surface TVa of the display device TV.

[0027] When the mounting base 30 is fixed to the rear surface TVa of the display device TV, the edges 32 and 33 come into contact with the rear surface TVa of the display device TV, while the main portion 31 protrudes from the edges 32 and 33 and is spaced apart from the rear surface TVa of the display device TV. That is, the edges 32 and 33 of the mounting base 30 function as support members that support the main portion 31 so as to keep it spaced apart from the rear surface TVa of the display device TV. This prevents the plate-like portion 12a, which is the top of the protrusion 12, from contacting and interfering with the rear surface TVa of the display device TV when the protrusion 12 is inserted into the opening 30a of the main portion 31. As a result, when the mounting base 30 is attached to the protrusion 12, it can be smoothly rotated around the protrusion 12 as a rotation center, facilitating fine adjustment of the angle of the second member 2 relative to the first member 1. The mounting base 30 is not limited to the above-described shape, as long as it has an opening 30a through which the protrusion 12 can be inserted.

[0028] 1 to 9 , the insertion hole forming portion 40 has a second plate-shaped portion 41 and a second bent portion 42 that is bent from the second plate-shaped portion 41 and has an insertion hole 40a, which is a through hole, formed therein. For example, in this embodiment, the insertion hole forming portion 40 is a member that is provided away from the mounting base 30. When the second member 2 is mounted on the rear surface TVa of the display device TV, the insertion hole forming portion 40 is mounted on the rear surface TVa of the display device TV so as to be positioned vertically below the mounting base 30.

[0029] In this way, by configuring the second member 2 so that the mounting portion 30 and the insertion hole forming portion 40 are spaced apart, it becomes easier to adjust the distance between the mounting portion 30 and the insertion hole forming portion 40. Therefore, it is possible to easily adjust the distance between the mounting portion 30 and the insertion hole forming portion 40 depending on the size and weight of the display device TV to be installed on the wall surface Wa. Therefore, when installing a display device TV on the wall surface Wa using the wall hanger 100, the range of sizes and weights of display devices TVs that can be installed can be expanded, making it possible to realize a highly versatile wall hanger 100.

[0030] A plurality of through holes 40h are formed in the second plate-shaped portion 41. A fixing member such as a nail, screw, bolt, or the like is inserted into each of the plurality of through holes 40h, thereby fixing the second plate-shaped portion 41 to the rear surface TVa of the display device TV (see FIG. 5). That is, the insertion hole forming portion 40 is fixed to the rear surface TVa of the display device TV. Note that the fixing members inserted into the plurality of through holes 40h may be any member as long as they can fix the second plate-shaped portion 41 to the rear surface TVa of the display device TV.

[0031] The second bent portion 42 bends from the lower end of the second plate-shaped portion 41 in a direction away from the rear surface TVa of the display device TV when the second plate-shaped portion 41 is attached to the rear surface TVa of the display device TV.

[0032] For example, when the second member 2 is attached to the first member 1, the insertion hole forming portion 40 is disposed so as to face and separate from the elongated hole forming portion 20. Specifically, of the insertion hole forming portion 40, the second plate-shaped portion 41 faces and separates from the first plate-shaped portion 21 in the elongated hole forming portion 20, and the second bent portion 42 faces and separates from the first bent portion 22 in the elongated hole forming portion 20.

[0033] The longitudinal direction of the second bent portion 42 is a direction along the longitudinal direction of the first bent portion 22 in the elongated hole forming portion 20. In the example of the present embodiment, the longitudinal direction of the second bent portion 42 is the Y direction, which is the same as the longitudinal direction of the first bent portion 22 in the elongated hole forming portion 20. In the present embodiment, the second bent portion 42 is provided to extend linearly.

[0034] The second plate-shaped portion 41 and the second bent portion 42 may be integrally formed by bending a single plate, or the second plate-shaped portion 41 and the second bent portion 42 may be formed separately and then fixed to each other by connecting them with fixing members such as screws, bolts or the like.

[0035] At least one insertion hole 40a (see FIG. 7) is formed in the second bent portion 42 as a through hole for inserting the regulating member 3. The insertion hole 40a may have any shape that allows the inserted regulating member 3 to be fixed. For example, if the regulating member 3 is a screw or a bolt, the insertion hole 40a may have a thread groove formed on the inner side surface, which allows the inserted regulating member 3 to be fixed. Also, if the regulating member 3 is a bolt or a nut, the insertion hole 40a may not have a thread groove formed on the inner side surface, and may have any shape that allows the shaft portion of the regulating member 3 to be inserted therein.

[0036] When the second member 2 is attached to the first member 1, the insertion hole 40a overlaps with the elongated hole 20a formed in the first bending portion 22. The restricting member 3 is inserted into the insertion hole 40a and the elongated hole 20a, which overlap each other in this way, and the restricting member 3, which is, for example, a screw or a bolt, is screwed into the insertion hole forming portion 40, thereby fixing the angle (i.e., attitude) of the insertion hole forming portion 40 relative to the elongated hole forming portion 20. In other words, the angle (i.e., attitude) of the display device TV, to which the second member 2 is attached, relative to the wall surface Wa, to which the first member 1 is attached, is fixed.

[0037] In this embodiment 1, the second bent portion 42 in which the insertion hole 40a is formed is positioned above the first bent portion 22 in which the long hole 20a is formed, but this is not limited to this, and the second bent portion 42 in which the insertion hole 40a is formed may also be positioned below the first bent portion 22 in which the long hole 20a is formed.

[0038] Furthermore, although only one insertion hole 40a may be formed in the second bent portion 42, from the standpoint of the strength for fixing the angle (i.e., posture) of the second member 2 relative to the first member 1, it is preferable that multiple insertion holes 40a be formed in the second bent portion 42, and that a regulating member 3 be inserted into each of the multiple insertion holes 40a so that the first bent portion 22 and the second bent portion 42 are fixed by the multiple regulating members 3.

[0039] In this embodiment, three insertion holes 40a are formed in the second bent portion 42 so as to be aligned in a row in the longitudinal direction (Y direction) of the second bent portion 42. The three insertion holes 40a are arranged so as to overlap the three elongated holes 20a1. Three restricting members 3 are inserted through the three insertion holes 40a and the elongated holes 20a1 that overlap with the three insertion holes 40a, respectively, and are, for example, screwed together. This fixes the position of the second bent portion 42 relative to the first bent portion 22 by the restricting members 3. Therefore, in the wall hanging device 100 according to this embodiment, the angle (i.e., attitude) of the second member 2 relative to the first member 1 is more firmly fixed. Note that the insertion hole forming portion 40 is not limited to the above-described shape, as long as it has at least one insertion hole 40a that can overlap the elongated hole 20a.

[0040] As described above, the wall hanger 100 includes a first member 1, a second member 2, and a restricting member 3. The first member 1 is formed with a protrusion 12 that protrudes in the Y direction (first direction). The second member 2 is formed with an opening 30a into which the protrusion 12 is inserted. The second member 2 is attached to the first member 1 so as to be rotatable around the protrusion 12 as a rotation center by inserting the protrusion 12 into the opening 30a. The restricting member 3 restricts rotation of the second member 2 that is attached to the first member 1 so as to be rotatable around the protrusion 12 as a rotation center. Specifically, the first member 1 is formed with an elongated hole 20a whose longitudinal direction is a direction (e.g., the X direction) that intersects the Y direction (first direction), and the second member 2 is formed with an insertion hole 40a into which the restricting member 3 is inserted. The restricting member 3 is inserted into the elongated hole 20a and the insertion hole 40a, which overlap with each other, to restrict rotation of the second member 2 relative to the first member 1.

[0041] In this way, after the restricting member 3 is inserted into the overlapping elongated hole 20a and the insertion hole 40a, the second member 2 attached to the first member 1 can freely and finely adjust its angle (i.e., orientation) relative to the first member 1 around the protrusion 12 as the center of rotation within a range of the longitudinal length L (see FIG. 9 ) of the elongated hole 20a, the longitudinal direction of which is a direction (e.g., the X direction) in which the protrusion 12 protrudes. After the angle (i.e., orientation) of the second member 2 relative to the first member 1 is finely adjusted, the restricting member 3 is, for example, screwed into the second member 2, thereby fixing the angle (i.e., orientation) of the second member relative to the first member 1. That is, the restricting member 3 is inserted into the overlapping elongated hole 20a and the insertion hole 40a, and restricts the rotation of the second member 2 relative to the first member 1. Furthermore, if it becomes necessary to adjust the angle (i.e., attitude) of the second member 2 relative to the first member 1 again, the force (e.g., the degree of screw engagement) with which the restricting member 3 restricts the rotation of the second member 2 relative to the first member 1 can be loosened, allowing the second member 2 to rotate around the protrusion 12 of the first member 1 as the center of rotation, making it easy to fine-tune the angle (i.e., attitude) of the second member 2 relative to the first member 1. In this way, with the wall hanger 100 according to this embodiment, it is easy to fine-tune the attitude of the second member relative to the first member 1 after the first member 1 has been attached to the second member.

[0042] As described above, the elongated hole forming portion 20 has a first plate-shaped portion 21 and a first bent portion 22 bent from the first plate-shaped portion 21 and having the elongated hole 20a formed therein. The insertion hole forming portion 40 has a second plate-shaped portion 41 and a second bent portion 42 bent from the second plate-shaped portion 41 and having the insertion hole 40a formed therein. By inserting the restricting member 3 into the overlapping elongated hole 20a and the insertion hole 40a, the first bent portion 22 and the second bent portion 42 are fixed to each other by the restricting member 3. This provides a configuration in which the angle (i.e., posture) of the second member relative to the first member is fixed. That is, by inserting the restricting member 3 into the overlapping elongated hole 20a and the insertion hole 40a, a configuration in which the rotation of the second member 2 relative to the first member 1 is restricted can be provided.

[0043] [Embodiment 2] A wall hanger 100 according to a second embodiment will be described with reference to Figs. 10 to 17. Fig. 10 is a plan view showing the configuration of the wall hanger 100 according to the second embodiment. Fig. 11 is a cross-sectional view showing the configuration of the wall hanger 100 according to the second embodiment. Fig. 12 is a bottom view of the wall hanger 100 according to the second embodiment. Fig. 13 is a cross-sectional view of the first member 1 according to the second embodiment. Fig. 14 is a plan view of the first member 1 according to the second embodiment. Fig. 15 is a plan view of the second member 2 according to the second embodiment. Fig. 16 is a cross-sectional view of the second member 2 according to the second embodiment. Fig. 17 is a bottom view of the second member 2 according to the second embodiment.

[0044] As shown in Figures 10, 11, 13 and 14, the first member 1 provided in the wall hanging device 100 according to the second embodiment differs from the first member 1 according to the first embodiment in that the protrusion forming portion 10 and the long hole forming portion 20 are not separate but are integrally formed.

[0045] In the second embodiment, the protrusion forming portion 10 includes a protrusion 12 and a support portion 11 on which the protrusion 12 is formed, similar to the first embodiment. Also, in the second embodiment, the long hole forming portion 20 includes a first plate-shaped portion 21 and a first bent portion 22, similar to the first embodiment. In the second embodiment, the support portion 11 and the first plate-shaped portion 21 are integrally and continuously formed.

[0046] In this way, in embodiment 2, the first member 1 has the protrusion forming portion 10, in which the protrusion portion 12 is formed, and the long hole forming portion 20, in which the long hole 20a is formed, integrally formed, thereby making it easy to attach the first member 1 to the wall surface Wa of the wall W (see Figure 4), and forming a wall hanging device 100 that makes the installation work easier.

[0047] For example, the support portion 11 and the first plate-shaped portion 21 may be integrally formed by, for example, bending and punching a single continuous metal plate. Furthermore, the support portion 11, the first plate-shaped portion 21, and the first bending portion 22 may be integrally formed by, for example, bending and punching a single continuous metal plate. Note that the support portion 11 and the first plate-shaped portion 21 may be connected to each other via a connecting member such as a metal plate, so that the protrusion-forming portion 10 and the elongated hole-forming portion 20 are configured as a single member that can be handled integrally.

[0048] As shown in Figures 10, 11, 15 and 16, the second member 2 provided in the wall hanging device 100 according to the second embodiment differs from the second member 2 according to the first embodiment in that the mounting portion 30 and the insertion hole forming portion 40 are not separate but are integrally formed.

[0049] In the second embodiment, the mounting portion 30 has an opening 30a formed therein, similar to the first embodiment. Also, in the second embodiment, the insertion hole forming portion 40 has a second plate-shaped portion 41 and a second bent portion 42, similar to the first embodiment. In the second embodiment, the mounting portion 30 and the second plate-shaped portion 41 are integrally and continuously formed.

[0050] In this way, in embodiment 2, the second member 2 is formed integrally with the mounting portion 30 having the opening 30a and the insertion hole forming portion 40 having the insertion hole, thereby making it easy to mount the second member 2 on the back surface TVa (see Figure 5) of the display device TV, and forming a wall hanging device 100 that makes the mounting work easier.

[0051] For example, the attachment portion 30 and the second plate-shaped portion 41 may be integrally formed by, for example, bending and drilling a single continuous metal plate. Furthermore, the attachment portion 30, the second plate-shaped portion 41, and the second bent portion 42 may be integrally formed by, for example, bending and drilling a single continuous metal plate. Note that the attachment portion 30 and the second plate-shaped portion 41 may be connected to each other via a connecting member such as a metal plate, so that the attachment portion 30 and the insertion hole forming portion 40 are configured as a single member that can be handled integrally.

[0052] In the second embodiment, as shown in FIG. 12, an example is shown in which one elongated hole 20a is formed in the first bent portion 22, and as shown in FIG. 17, an example is shown in which one insertion hole 40a is formed in the second bent portion 42. With this configuration, as shown in FIGS. 10 to 17, after the restricting member 3 is inserted into the mutually overlapping elongated hole 20a and insertion hole 40a, the second member 2 attached to the first member 1 can be freely and finely adjusted in angle (i.e., attitude) relative to the first member 1 around the protrusion 12 as the center of rotation within the range of the longitudinal length L (see FIG. 12) of the elongated hole 20a, the longitudinal direction of which is the direction (e.g., the X direction) in which the protrusion 12 protrudes. After the angle (i.e., attitude) of the second member 2 relative to the first member 1 is finely adjusted, the restricting member 3 can be, for example, screwed in, thereby fixing the angle (i.e., attitude) of the second member relative to the first member. That is, the restricting member 3 can be inserted into the overlapping elongated hole 20a and the insertion hole 40a to restrict the rotation of the second member 2 relative to the first member 1. Furthermore, even if it becomes necessary to adjust the angle (i.e., attitude) of the second member 2 relative to the first member 1 again, the angle (i.e., attitude) of the second member 2 relative to the first member 1 can be easily fine-tuned by loosening the force (e.g., the degree of screw engagement) with which the restricting member 3 fastens the first member 1 and the second member 2. In this way, in the wall hanger 100 according to the second embodiment as well, it is easy to fine-tune the attitude of the second member relative to the first member after attaching the first member 1 to the second member.

[0053] In addition, in embodiment 2, the first bent portion 22 may have multiple long holes 20a aligned in the Y direction, and the second bent portion 42 may have multiple insertion holes 40a aligned in the Y direction.

[0054] Fig. 18 is a plan view of a wall hanger 100 according to a modified example of the second embodiment. As shown in Fig. 18, the first bent portion 22 and the second bent portion 42 may each have an arc-shaped curve when viewed in plan (when viewed from the normal direction of the second member 2). In the example shown in Fig. 18, the first bent portion 22 and the second bent portion 42 each have a shape that forms part of a circle when the protrusion 12 is the center of the concentric circle. It is preferable that the first bent portion 22 or the second bent portion 42, whichever is closer to the protrusion 12, has an arc-shaped shape.

[0055] In this way, it is preferable that the one of the first bent portion 22 and the second bent portion 42 that is closer to the protrusion 12 has an arc-shaped curved shape. This makes it possible to prevent a part of the second bent portion 42, such as a corner of the second bent portion 42 or a surface of the second bent portion 42 that faces the first bent portion 22, from coming into contact with the first bent portion 22 when the second member 2 is rotated around the protrusion 12 as the center of rotation. This makes it possible to configure a wall hanger 100 that allows for smoother fine adjustment of the angle of the second member 2 relative to the first member 2.

[0056] In addition, by making the first bent portion 22 and the second bent portion 42, in addition to the one closer to the protrusion 12, also the one farther from the protrusion 12, curved in an arc shape, it is possible to configure a wall hanger 100 that is smaller in size and lighter in weight. This makes it possible to obtain a wall hanger 100 that makes it even easier to attach the display device TV to the wall W.

[0057] The present disclosure is not limited to the configurations of the above-described embodiments and modified examples, and may be replaced with a configuration that is substantially identical to the configurations shown in the above-described embodiments and modified examples, a configuration that has the same effect, or a configuration that can achieve the same purpose.
