[Figure 8]FIG. 10 is a perspective view showing an example of a mounting structure for a display device according to a third embodiment of the present invention. [Figure 9] FIG. 10 is a schematic diagram illustrating an example of a conventional mounting structure for a display device. DETAILED DESCRIPTION OF THE INVENTION

[0008] Conventionally, a swivel mechanism as shown in FIG. 9 is known that can change the orientation of a display screen by rotating the display screen left and right without moving the stand.

[0009] As indicated by reference numeral 900A, the display device 10 has a swivel section 40 that rotatably supports the display unit main body 20 relative to the support section 310 of the stand 30. Here, when viewing the display device 10 from the front, the direction toward the left in the width direction of the display device 10 is referred to as the X1 direction, and the direction opposite the X1 direction is referred to as the X2 direction. The direction from the rear side to the front side of the display device 10 is referred to as the Y1 direction, and the direction opposite the Y1 direction is referred to as the Y2 direction. When X1 and X2, and Y1 and Y2 are not distinguished from each other and are referred to collectively as the X direction and the Y direction, respectively, the intersection of the center of the X direction and the center of the Y direction of the display unit main body 20, as indicated on the top surface of the display unit main body 20, is referred to as the center P10 of the display unit main body 20 (see reference numerals 900C and 900D). Furthermore, the position of the center line of the display main body 20 in the Y direction when the display main body 20 faces the front side of the display device 10 is defined as center line C10 (see symbols 900C and 900D). When the display main body 20 faces the front side of the display device 10, center P10 is located on center line C10.

[0010] As indicated by the reference symbol 900B, the display device 10 is placed in front of a wall H located on the rear side of the display device 10. In this case, if a user on the X1 side of the display device 10 rotates the display main body 20 in the Q1 direction (clockwise when viewed from the front side of the display device 10) to make it easier to view the display screen 210, the left end 250 of the display main body 20 will hit the wall H, and the display main body 20 will not be able to be rotated any further.

[0011] As shown by reference numerals 900C and 900D, when the display main body 20 is rotated in the Q1 direction, the swivel unit 40 causes the display main body 20 to rotate around the axis of the support unit 310 as the rotation axis, along the outer periphery 310a of the support unit 310. As the display main body 20 rotates, the center P10 of the display main body 20 also rotates around the axis of the support unit 310 as the rotation axis, and moves in the Y2 direction (towards the rear side) by a length W10 from the center line C10. In this way, with a conventional swivel mechanism, when the display main body 20 is rotated, the center P10 of the display main body 20 moves towards the rear side (Y2 direction).

[0012] The swivel mechanism of the display device 1 according to this embodiment is configured so that when the display main body 2 is rotated, the center of the display main body 2 moves to the front side (Y1 direction), making it less likely for the display main body 2 to come into contact with an obstruction such as a wall H behind the display device 1. Details of the swivel mechanism of the display device 1 will be described later.

[0013] [Embodiment 1] <Appearance of mounting structure> A first embodiment of the present invention will be described below with reference to the drawings. A display device 1 according to the present invention can be applied to, for example, television sets, liquid crystal displays of computers, liquid crystal displays connected to various game devices, information displays, etc.

[0014] FIG. 1 is a perspective view showing an example of a mounting structure for a display device 1 according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view showing an example of the mounting structure for the display device 1. As shown in FIG.

[0015] 1 and 2, the display device 1 includes a display main body (main unit) 2, a stand 3, and a swivel unit 4. The display main body 2 is attached to the stand 3 via the swivel unit 4 so as to be rotatable in the left-right direction.

[0016] The display main body 2 includes a display screen 21, a first fitting portion 22, and a second fitting portion 23. The display screen 21 is realized by, for example, a liquid crystal display, an organic EL display, a plasma display, or the like, and displays images and various information, etc.

[0017] The first fitting portion 22 and the second fitting portion 23 are a pair of recesses formed in the display unit main body 2 for attaching the swivel unit 4 to the display unit main body 2. A first fixing portion 412 of a first swivel unit 41 (described later) is fitted into the first fitting portion 22, and a second fixing portion 422 of a second swivel unit 42 is fitted into the second fitting portion 23. The first fixing portion 412 and the second fixing portion 422 are fixed to the first fitting portion 22 and the second fitting portion 23 by bolts 24.

[0018] The stand 3 rotatably supports the display main body 2 via the swivel unit 4. A third fixing portion 413 of the first swivel unit 41 and a fourth fixing portion 423 of the second swivel unit 42, which will be described later, are fixed to the stand 3.

[0019] (Swivel part 4) The swivel unit 4 is configured as a pair, and includes a first swivel unit (first connecting member) 41 and a second swivel unit (second connecting member) 42. The first swivel unit 41 and the second swivel unit 42 connect the display unit main body 2 and the stand 3 together.

[0020] The first swivel portion 41 includes a connecting portion 411, a first fixed portion 412, and a third fixed portion 413. The connecting portion 411 is rotatably connected to the first fixed portion 412 by a link pin (bolt) LP1 around a first rotation axis J1, and is rotatably connected to the third fixed portion 413 by a link pin (bolt) LP3 around a third rotation axis J3. As described above, the first fixed portion 412 is fitted into the first fitting portion 22 and fixed to the display main body 2 by the bolt 24. The third fixed portion 413 is fixed to the stand 3.

[0021] As a result, the first swivel part 41 is rotatably connected to the display main body 2 about the first rotation axis J1, and is rotatably connected to the stand 3 about the third rotation axis J3.

[0022] The second swivel unit 42 has the same configuration as the first swivel unit 41, and includes a connecting unit 421, a second fixed unit 422, and a fourth fixed unit 423. The connecting unit 421 is rotatably connected to the second fixed unit 422 about the second rotation axis J2 by ​​a link pin (bolt) LP2, and is rotatably connected to the fourth fixed unit 423 about the fourth rotation axis J4 by a link pin (bolt) LP4. As described above, the second fixed unit 422 is fitted into the second fitting unit 23 and fixed to the display unit main body 2 by the bolt 24. The fourth fixed unit 423 is fixed to the stand 3.

[0023] As a result, the second swivel portion 42 is rotatably connected to the display main body 2 about the second rotation axis J2, and is rotatably connected to the stand 3 about the fourth rotation axis J4.

[0024] Additionally, the first swivel unit 41 and the second swivel unit 42 are disposed on the front side of the display device 1. As will be described in detail later, this allows the display main body 2 to move toward the front side of the display device 1 (in the Y1 direction) when the display main body 2 is rotated.

[0025] <Trapezoidal link structure of swivel part 4> 3 is a schematic diagram illustrating the trapezoidal link of the swivel unit 4, and is a view of the swivel unit 4 viewed from above. As shown in Fig. 3, a four-bar link is formed by the first swivel unit 41, the second swivel unit 42, a portion of the display unit main body 2 between the first rotation axis J1 and the second rotation axis J2 (hereinafter referred to as the "main body link portion Lk1": the portion indicated by the line connecting the first rotation axis J1 and the second rotation axis J2), and a portion of the stand 3 between the third rotation axis J3 and the fourth rotation axis J4 (hereinafter referred to as the "stand link portion Lk2": the portion indicated by the line connecting the third rotation axis J3 and the fourth rotation axis J4).

[0026] In addition, the first fitting portion 22, the second fitting portion 23, the third fixing portion 413, and the fourth fixing portion 423 are arranged so that the length L1 between the first rotation axis J1 and the second rotation axis J2 is smaller than the length L2 between the third rotation axis J3 and the fourth rotation axis J4.

[0027] As will be described in more detail later, by configuring a four-bar link in which the length L1 is smaller than the length L2, when the display main body 2 is rotated, the center P1 of the display main body 2 can be moved to the front side.

[0028] The four-bar link may also be a trapezoidal link. In this case, the length of the connecting portion 411 in the longitudinal direction is the same as the length of the connecting portion 421 in the longitudinal direction, and the length L3 between the first rotation axis J1 and the third rotation axis J3 is the same as the length L4 between the second rotation axis J2 and the fourth rotation axis J4. Note that as long as the length L3 and the length L4 are the same, the length of the connecting portion 411 in the longitudinal direction does not have to be the same as the length of the connecting portion 421 in the longitudinal direction.

[0029] Furthermore, the first fitting portion 22, the second fitting portion 23, the third fixing portion 413, and the fourth fixing portion 423 are arranged so that the main body link portion Lk1 and the stand link portion Lk2 are parallel with each other when the display main body 2 is facing the front side of the display device 1. As a result, a trapezoidal link is formed by the connecting portion 411, the connecting portion 421, the main body link portion Lk1, and the stand link portion Lk2. By forming the trapezoidal link, the connecting portion 411 and the connecting portion 421 have the same length, making it easier to face the display main body 2 toward the front side of the display device 1.

[0030] It should be noted that the length L3 and the length L4 do not have to be the same, and the main body link portion Lk1 and the stand link portion Lk2 do not have to be parallel to each other.

[0031] (Trapezoidal link operation) 4 is a schematic diagram illustrating the operation of the trapezoidal link. The diagram indicated by reference numeral 400A is a plan view showing a state in which the display main body 2 faces the front side of the display device 1. The diagram indicated by reference numeral 400B is a plan view showing a state in which the display main body 2 has been rotated in the Q1 direction (clockwise when viewed from the front side of the display device 1). The diagram indicated by reference numeral 400C is a plan view showing a state in which the display main body 2 has been further rotated in the Q1 direction.

[0032] Here, the intersection of the center of the display main body 2 in the X direction and the center of the display main body 2 in the Y direction, as shown on the top surface of the display main body 2, is defined as the center P1 of the display main body 2. Furthermore, when the display main body 2 faces the front side of the display device 1, the position of the center line of the display main body 2 in the Y direction is defined as the center line C1.

[0033] As indicated by the reference numeral 400A, a trapezoidal link is formed by the connecting portion 411, the connecting portion 421, the main body link portion Lk1, and the stand link portion Lk2. When the display main body 2 faces the front side of the display device 1, the center P1 is located on the center line C1.

[0034] Because the third fixing portion 413 and the fourth fixing portion 423 are fixed to the stand 3, the third fixing portion 413 and the fourth fixing portion 423 do not move even when the display main body 2 is rotated. On the other hand, because the first fixing portion 412 and the second fixing portion 422 are fixed to the display main body 2, when the display main body 2 is rotated, the first fixing portion 412 and the second fixing portion 422 also move as the display main body 2 moves.

[0035] As indicated by reference numerals 400B and 400C, when the display main body 2 is rotated in the Q1 direction, the first fixed portion 412 and the second fixed portion 422 rotate in the Q2 direction (see FIG. 5, counterclockwise when viewed from the front side of the display device 1) around the third rotation axis J3 and the fourth rotation axis J4, respectively. At this time, because the swivel portion 4 is provided with a trapezoidal link, the first fixed portion 412 and the second fixed portion 422 rotate while maintaining the lengths L1 to L4.

[0036] As a result, the entire display main body 2 protrudes toward the front, and the center P1 of the display main body 2 moves toward the front (Y1 direction). Since the protrusion of the end 25 of the display main body 2 toward the rear (Y2 direction) is reduced, it becomes less likely to come into contact with an obstruction such as a wall H behind the display device 1.

[0037] Fig. 5 is a schematic diagram illustrating an example of movement of the display main body 2 toward the front side. As shown in Fig. 5, when the display main body 2 is rotated in the Q1 direction, the first fixing part 412 and the second fixing part 422 rotate in the Q2 direction around the third rotation axis J3 and the fourth rotation axis J4, respectively, in accordance with the rotational movement of the display main body 2. As a result, the center P1 of the display main body 2 moves toward the front side (Y1 direction) by W1 toward the center P1a.

[0038] As an example, if the display device 1 is 65 inches, the length L10 in the X direction of the display main body 2 is approximately 144 cm. The length L1 between the first rotation axis J1 and the second rotation axis J2 is approximately 12 cm, and the length L2 between the third rotation axis J3 and the fourth rotation axis J4 is approximately 13 cm. The length L3 between the first rotation axis J1 and the third rotation axis J3 and the length L4 between the second rotation axis J2 and the fourth rotation axis J4 are the same length, approximately 8 cm each.

[0039] In this example, when the display main body 2 is rotated 20° in the Q1 direction, the amount of movement W1 of the center P1 of the display main body 2 toward the front side is approximately 5 cm. As a result, compared to a display device not equipped with the swivel unit 4 according to the present invention, there is an additional approximately 5 cm in the distance from the rear wall H when the display main body 2 is rotated, and therefore the display main body 2 can be rotated by that amount.

[0040] The size of the display device 1 is not limited to this, and may be larger or smaller than the above size.

[0041] <Support member 50> 6 is a schematic diagram illustrating an example of the support member 50. The diagram indicated by reference numeral 600A is a schematic diagram of the display device 1 as seen from the side, the diagram indicated by reference numeral 600B is a side view of the support member 50, and the diagram indicated by reference numeral 600C is a perspective view of the support member 50.

[0042] As shown by reference numeral 600A, the display main body 2 is attached to the free end portions 45 of the connecting portions 411 and 421, and therefore a large rotation moment F due to the weight of the display main body 2 is applied to the free end portions 45.

[0043] For this reason, as indicated by the reference numeral 600B, each of the connecting parts 411 and 421 includes a support member 50 that supports the display main body 2 on the surface opposite to the surface facing the display main body 2. The support member 50 is disposed between the connecting parts 411 and 421 and the stand 3. This makes it possible to prevent the connecting parts 411 and 421 from being deformed or damaged by the rotation moment F.

[0044] Furthermore, as indicated by the reference numeral 600C, the support member 50 may be configured to include, for example, rollers so that it can rotate and move on the stand 3. By making the support member 50 rotatable, friction between the support member 50 and the stand 3 can be reduced, allowing the display main body 2 to rotate smoothly.

[0045] Note that a rail, a recess, or the like may be provided along the path of movement of the support member 50 at the portion where the support member 50 moves on the stand 3. This allows the display main body 2 to rotate more smoothly.

[0046] In the above example, the display device 1 is placed on, for example, the floor, a desk, a TV stand, etc., but it may also be mounted on a wall, a ceiling, etc. When mounting the display device 1 on a ceiling, the stand 3 is attached to the top surface of the display main body 2 via the swivel unit 4 so that the display main body 2 can rotate left and right, and the stand 3 is attached to the ceiling. When mounting the display device 1 on a wall, the stand 3 is attached to the side of the display main body 2 via the swivel unit 4 so that the display main body 2 can rotate up and down, and the stand 3 is attached to the wall.

[0047] [Embodiment 2] A second embodiment of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the first embodiment, and the description thereof will not be repeated.

[0048] As described above, in the first swivel unit 41 of the first embodiment, the connecting portion 411 is rotatably connected to the first fixed portion 412 and the third fixed portion 413. The first fixed portion 412 is fixed to the display main body 2, and the third fixed portion 413 is fixed to the stand 3. The second swivel unit 42 has the same configuration as the first swivel unit 41. As a result, the display main body 2 is rotatably connected to the stand 3 via the first swivel unit 41 and the second swivel unit 42.

[0049] On the other hand, the swivel section 4A of the second embodiment has a sliding section that slidably fits with the fitting section of the display main body 2A and the fitting section of the stand 3A, respectively.

[0050] Fig. 7 is a perspective view showing an example of the mounting structure of a display device 1A according to embodiment 2 of the present invention. As shown in Fig. 7, a display main body 2A includes a first fitting portion 22A (fitting portion) and a second fitting portion (fitting portion) 23A. The first fitting portion 22A and the second fitting portion 23A are a pair of cylindrical recesses formed in the display main body 2A for mounting a pair of swivel portions 4A to the display main body 2A.

[0051] A first sliding portion (cylindrical portion) 412A of the first swivel portion 41A is slidably fitted into the first fitting portion 22A, and a second sliding portion (cylindrical portion) 422A of the second swivel portion 42A is slidably fitted into the second fitting portion 23A.

[0052] The stand 3A includes a third fitting portion (fitting portion) 31 and a fourth fitting portion (fitting portion) 32. The third fitting portion 31 and the fourth fitting portion 32 are a pair of cylindrical recesses formed in the stand 3A for attaching the pair of swivel portions 4A to the stand 3A.

[0053] The third sliding portion (cylindrical portion) 413A of the first swivel portion 41A is slidably fitted into the third fitting portion 31, and the fourth sliding portion (cylindrical portion) 423A of the second swivel portion 42A is slidably fitted into the fourth fitting portion 32.

[0054] The first swivel portion 41A includes a connecting portion 411A, a first sliding portion 412A, and a third sliding portion 413A. The first sliding portion 412A is a cylindrical portion provided at the end of the connecting portion 411A on the display main body 2A side, and has a central axis on the first rotation axis J1. The first sliding portion 412A is fitted into the first fitting portion 22A so as to be rotatable while sliding around the first rotation axis J1.

[0055] The third sliding portion 413A is a cylindrical portion provided at the end of the connecting portion 411A on the stand 3A side, and has a central axis on the third rotation axis J3. The third sliding portion 413A is fitted into the third fitting portion 31 so as to be rotatable while sliding about the third rotation axis J3.

[0056] As a result, the first swivel portion 41A is rotatably connected to the display main body 2A while sliding about the first rotation axis J1, and is rotatably connected to the stand 3A while sliding about the third rotation axis J3.

[0057] The second swivel portion 42A includes a connecting portion 421A, a second sliding portion 422A, and a fourth sliding portion 423A. The second sliding portion 422A is a cylindrical portion provided at the end of the connecting portion 421A on the display main body 2A side, and has a central axis on the second rotation axis J2. The second sliding portion 422A is fitted into the second fitting portion 23A so as to be rotatable while sliding about the second rotation axis J2.

[0058] The fourth sliding portion 423A is a cylindrical portion provided at the end of the connecting portion 421A on the stand 3A side, and has a central axis on the fourth rotation axis J4. The fourth sliding portion 423A is fitted into the fourth fitting portion 32 so as to be rotatable while sliding around the fourth rotation axis J4.

[0059] As a result, the second swivel portion 42A is rotatably connected to the display main body 2A while sliding about the second rotation axis J2, and is rotatably connected to the stand 3A while sliding about the fourth rotation axis J4.

[0060] The connecting portion 411A, the connecting portion 421A, the main body link portion Lk1, and the stand link portion Lk2 form a trapezoidal link.

[0061] As a result, when the display main body 2A is rotated, the display main body 2A protrudes overall toward the front, and the center P1 of the display main body 2A moves toward the front (in the Y1 direction), making it less likely to come into contact with obstructions such as a wall H behind the display device 1A.

[0062] [Embodiment 3] A third embodiment of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the first embodiment, and the description thereof will not be repeated.

[0063] As described above, in the first swivel unit 41 of the first embodiment, the connecting portion 411 is rotatably connected to the first fixed portion 412 and the third fixed portion 413. The first fixed portion 412 is fixed to the display main body 2, and the third fixed portion 413 is fixed to the stand 3. The second swivel unit 42 has the same configuration as the first swivel unit 41. As a result, the display main body 2 is rotatably connected to the stand 3 via the first swivel unit 41 and the second swivel unit 42.

[0064] On the other hand, in the swivel section 4B of the third embodiment, the first swivel section 41B and the second swivel section 42B are configured as a pair of disks, and the first swivel section 41B and the second swivel section 42B connect the display main body 2B and the stand 3B.

[0065] Fig. 8 is a perspective view showing an example of the mounting structure of a display device 1B according to embodiment 3 of the present invention. As shown in Fig. 8, a display main body 2B includes a first fitting portion 22B and a second fitting portion 23B. The first fitting portion 22B and the second fitting portion 23B are a pair of recesses formed in the display main body 2B for mounting a pair of swivel portions 4B to the display main body 2B.
