Description

[Technical Field]

[0001] The present disclosure relates to a stand and a display device. [Background technology]

[0002] A display device typically has a structure in which a display unit including a display screen is attached to a base such as a stand, so that it can be placed on the floor, furniture, etc. Some display devices have a swivel mechanism that allows the angle of the display unit to be adjusted so that it can swing left and right without moving the stand. For example, Patent Document 1 discloses a swivel mechanism that shows a hinge plate attached to the display unit and a hinge base attached to the stand, and has one rotation shaft that rotatably supports the hinge plate relative to the hinge base.

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-25222 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to ensure room space and a sufficient viewing distance, display devices are generally installed with the rear surface opposite the display screen as close as possible to the wall. In a display device with a swivel mechanism, when the display unit is rotated in either the left or right direction, one end of the display screen in the left-right direction moves forward, and the other end moves backward. In particular, as the screen size of the display device increases, the width of the display screen increases, the amount of backward movement of the other end increases. Therefore, in a display device installed close to the wall, the other end that moves backward may collide with the wall, making it impossible to rotate the display screen to the angle that the swivel mechanism would normally allow. Furthermore, when a display device is installed so that the display screen can be rotated to the angle that the swivel mechanism would normally allow, the distance between the display device and the wall increases, resulting in problems such as reduced room space and an inability to ensure a sufficient viewing distance.

[0005] In view of the above-mentioned problems, the present disclosure provides a stand that reduces the distance that the display unit moves backward when the orientation of the display unit is rotated left or right using a swivel mechanism, and a display device that includes the stand. [Means for solving the problem]

[0006] A stand according to one embodiment of the present disclosure comprises a stand base having a first groove and a second groove arranged symmetrically with respect to an axis of symmetry, each of the first and second grooves including a first section extending in a direction intersecting the axis of symmetry from one end of each groove to a midpoint of each groove, and a second section extending from the midpoint of each groove to the other end of each groove and approaching the axis of symmetry as it moves away from the midpoint of each groove; and a support having a first insertion portion slidably inserted into the first groove and a second insertion portion slidably inserted into the second groove, such that when the first insertion portion is at one end of the first groove, the second insertion portion can slide in the second section of the second groove, and when the second insertion portion is at one end of the second groove, the first insertion portion can slide in the second section of the first groove.

[0007] A display device according to an aspect of the present disclosure includes the stand according to an aspect of the present disclosure and a display unit supported by the stand. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] The embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiments and modifications. Various modifications other than the embodiments and modifications are possible depending on the design, etc., as long as they do not deviate from the technical concept of the present disclosure.

[0010] <Embodiment 1> FIG. 1 is a schematic diagram of a display device 100 according to a first embodiment. The display device 100 is a display device capable of displaying images such as moving images and still images. Examples of such display devices include, but are not limited to, television sets and monitors used in personal computers. The lower left, upper right, upper left, lower right, upper, and lower sides of FIG. 1 correspond to the front, rear, right, left, upper, and lower sides of the display device 100, respectively.

[0011] <Display device> The display device 100 includes a display unit 101 and a stand 102. The display unit 101 has a rectangular plate-like shape. The display unit 101 is, for example, a display panel attached to a housing. Examples of the display panel include a liquid crystal panel, an organic LED display panel, and a quantum dot LED display panel, but the type of display panel is not particularly limited as long as it can display an image. The stand 102 is placed with its bottom side facing down on an installation surface. In FIG. 1 , the front surface of the display device 100 is the main surface of the display unit 101, which is the surface on which an image is displayed. In the present disclosure, for example, the surface on which an image is displayed is rectangular, and is installed so that the long sides are aligned in the left-right direction and the short sides are aligned in the up-down direction.

[0012] The stand 102 includes a support column 200 connected to the display unit 101, and a stand base 300 serving as a pedestal. The support column 200 stands upright on the stand base 300, and the upper end of the support column 200 is connected to the display unit 101. As a result, in the display device 100, the display unit 101 is supported above the installation surface of the stand 102 by the support column 200. In the first embodiment of the present disclosure, a configuration in which the support column 200 is made up of two cylindrical members, a first insertion section 210 and a second insertion section 220, is exemplified.

[0013] FIG. 2 is a schematic exploded view of the display device 100 according to the first embodiment. In FIG. 2, the structure of the hidden portion of the display unit 101 is indicated by dotted lines. The stand base 300 is provided with a first groove 310 and a second groove 320, which are grooves that open upward. As can be seen from FIGS. 1 and 2, the lower end of the first insertion portion 210 is inserted into the first groove 310, and the lower end of the second insertion portion 220 is inserted into the second groove 320. The first insertion portion 210 is inserted slidably along the first groove 310, and the second insertion portion 220 is inserted slidably along the second groove 320. As will be described in detail later, the stand 102 and the display device 100 according to the present disclosure realize a swivel function that can change the angle of the main surface of the display unit 101 so that the display unit 101 swivels left and right in a plan view by sliding the first insertion portion 210 and the second insertion portion 220 along the first groove 310 and the second groove 320.

[0014] <Strut> 1 and 2, in the first embodiment of the present disclosure, the support column 200 is configured to include two cylindrical members, the first insertion section 210 and the second insertion section 220. However, the structure of the support column 200 can be modified as appropriate. For example, the portion of the support column 200 connected to the display section 101 may be configured to include a single thick plate member, and the cylindrical first insertion section 210 and the second insertion section 220 may protrude from the bottom surface of the thick plate member to an extent that they can be inserted into the first groove 310 and the second groove 320. Furthermore, the structure connecting the support column 200 and the stand base 300 may be any structure as long as the first insertion section 210 can slide along the first groove 310 in an upright position, and the second insertion section 220 can slide along the second groove 320 in an upright position. For example, a structure can be adopted in which a long, thin hole is provided at the bottom of each of the first groove 310 and the second groove 320 along the entire length of each groove, and screws are passed through the bottom of each of these holes to fasten to the underside of the first insertion portion 210 and the underside of the second insertion portion 220, or a structure can be adopted in which a rail is provided at the bottom of each of the first groove 310 and the second groove 320 along the entire length of each groove, and the underside of the first insertion portion 210 and the underside of the second insertion portion 220 can engage with the rail and move along the rail.

[0015] <Details of the swivel function in the first embodiment> 3, 4, 5, and 6 are views of the display device 100 according to the first embodiment as viewed from above. The left, right, upper, and lower sides of FIGS. 3 to 6 correspond to the right, left, rear, and front sides of FIGS. 1 and 2, respectively. A plan view is a viewpoint when the front-to-back and left-to-right directions are considered to be planes. In addition, in FIGS. 3 to 6, the display unit 101 is shown in a transparent state with its outline indicated by dotted lines, and the first insertion unit 210 and the second insertion unit 220 are shown in cross section as viewed from above. The swivel function according to the first embodiment of the present disclosure will be described in detail below with reference to FIGS. 3 to 6.

[0016] <First Groove and Second Groove of First Embodiment> 3, in the stand base 300, the first groove 310 and the second groove 320 are arranged symmetrically with respect to an axis of symmetry 400 extending in the front-rear direction in a plan view. The first groove 310 includes a first section 313 extending in a left-right direction intersecting the front-rear direction from one end 311 to an intermediate position 314, and a second section 315 extending from the intermediate position 314 to the other end 312 and approaching the axis of symmetry 400 as it moves forward from the intermediate position 314. The second groove 320 includes a first section 323 extending in a left-right direction intersecting the front-rear direction from one end 321 to an intermediate position 324, and a second section 325 extending from the intermediate position 324 to the other end 322 and approaching the axis of symmetry 400 as it moves forward from the intermediate position 324.

[0017] In embodiment 1 of the present disclosure, in a planar view, one end 311 of the first groove 310 is closer to the axis of symmetry 400 than the midpoint 314 of the first groove 310, and one end 321 of the second groove 320 is closer to the axis of symmetry 400 than the midpoint 324 of the second groove 320.

[0018] 3 shows a case where the swivel angle is zero, that is, the front surface of the display unit 101 that displays an image faces directly ahead. In this case, the first insertion section 210 is located at a position between one end 311 and an intermediate position 314 in the first section 313, and the second insertion section 220 is located at a position between one end 321 and an intermediate position 324 in the first section 323.

[0019] As shown in FIG. 3 , in a plan view, the width of the first groove 310 is approximately the same as or slightly larger than the diameter of the first insertion portion 210 over the entire section of the first groove 310. When the first insertion portion 210 moves within the first groove 310 in the width direction of the first groove 310, that is, in a direction intersecting the extension direction of the first groove 310 in a plan view, the side surface 211 of the first insertion portion 210 abuts against the inner sidewall of the first groove 310, thereby restricting the movement of the first insertion portion 210 in the intersecting direction. On the other hand, when the first insertion portion 210 moves in the extension direction of the first groove 310, the side surface 211 of the first insertion portion 210 does not abut against the sidewall of the first groove 310, and the movement of the first insertion portion 210 is not restricted. Therefore, the first insertion portion 210 can slide along the extension direction of the first groove 310. The above description also applies to the second groove 320 and the second insertion portion 220 as shown in FIG. 3, and the second insertion portion 220 can slide along the direction in which the second groove 320 extends.

[0020] 3, the first section 313 of the first groove 310 may be provided with two locking portions 500 that protrude inward of the first section 313. Similarly, the first section 323 of the second groove 320 may be provided with two locking portions 500 that protrude inward of the first section 323. The two locking portions 500 are spaced apart in the left-right direction in which the first section 313 and the first section 323 extend so that the first insertion section 210 or the second insertion section 220 can be sandwiched between them from the left and right.

[0021] The locking portion 500 includes abutting portions 510 that protrude toward the inside of the first section 313 and the inside of the first section 323, and an elastic portion 520 that is elastically deformable toward the outside of the first section 313 and the outside of the first section 323. For example, in the first section 313, a recess may be formed in the side wall of the first groove 310, and the elastic portion 520 may be fixed in the recess on the outside of the first section 313, with the abutting portion 510 fixed to the elastic portion 520 protruding toward the inside of the first section 313. As shown in FIG. 3 , the first insertion portion 210 and the second insertion portion 220 are each locked between two locking portions 500. More specifically, inside the first section 313, the abutting portions 510 of the two locking portions 500 abut against the side surfaces 211 of the first insertion portion 210 from the left and right, thereby locking the first insertion portion 210. Furthermore, inside the first section 323, the abutting portions 510 of the two locking portions 500 abut against the side surfaces 221 of the second insertion portion 220 from the left and right, thereby locking the second insertion portion 220.

[0022] FIG. 4 shows an intermediate stage before the display unit 101 is rotated so as to swing toward the right. In FIG. 4, the display unit 101 is being moved to the left. Accordingly, the first insertion portion 210 moves inside the first section 313 toward the one end 311. Furthermore, the second insertion portion 220 moves inside the first section 323 toward the intermediate position 324. At this time, the elastic portion 520 of the locking portion 500, which is in the direction in which the first insertion portion 210 and the second insertion portion 220 slide, elastically deforms outward, and the abutting portion 510 moves outward of the first section 313 and the first section 323. As a result, the first insertion portion 210 and the second insertion portion 220 are released from the locking portion 500, and the first insertion portion 210 and the second insertion portion 220 become slidable.

[0023] 3 and 4, the abutment portion 510 may have an inclined portion 511 that is inclined with respect to the sliding direction of the first insertion portion 210 and the second insertion portion 220 in a plan view. For example, as can be seen from FIG. 4, when the first insertion portion 210 moves and presses the abutment portion 510, the direction of the force applied to the abutment portion 510 is changed to a force that presses the abutment portion 510 upward due to the inclined portion 511, causing the elastic portion 520 to elastically deform outward, and the abutment portion 510 to move outward from the first section 313. Therefore, the locking by the locking portion 500 can be released only by the force that moves the display unit 101, without applying a separate force that pushes the abutment portion 510 outward from the first section 313.

[0024] FIG. 5 shows an intermediate stage in which preparation for rotating the display unit 101 is complete. In FIG. 5, the first insertion portion 210 has moved to a position where it abuts against the one end 311, and the second insertion portion 220 has moved to an intermediate position 324. At this time, the first insertion portion 210 is engaged between the one end 311 and the locking portion 500. In other words, the side surface 211 of the first insertion portion 210 is sandwiched and engaged so as to contact the side wall of the first groove 310 at the one end 311 and the abutting portion 510 of the locking portion 500, respectively. This allows the first insertion portion 210 to rotate around the center of the cross section when viewed from above at the one end 311. Also, as shown in FIG. 5, the second insertion portion 220 can slide along the second section 325 of the second groove 320, which extends downward from the intermediate position 324.

[0025] 6 shows a state in which the display unit 101 has been rotated to the maximum angle at which the front surface on which the image is displayed faces rightward. As shown in FIG. 6, the swivel angle at this time is defined as angle θ. The center of rotation about the first insertion portion 210 at one end 311 is defined as center O.

[0026] The display unit 101 rotates around the first insertion portion 210 as an axis so as to face the display unit 101 to the right, and in response to this, the second insertion portion 220 slides downward along the second section 325. This allows the display device 100 of the present disclosure to realize a swivel mechanism that rotates the display unit 101 left and right to orient the screen in a desired direction. When the display unit 101 is rotated to the maximum angle towards the right, the second insertion portion 220 moves to the position of the other end 322 of the second groove 320.

[0027] As shown in Fig. 3, half the width of the display unit 101 in the left-right direction is W, and the distance between the right edge of the display unit 101 and the first insertion portion 210 is S1. From Fig. 6, the relationship of W>S1 is established. As shown in Fig. 6, when the swivel angle of the display unit 101 is angle θ, the distance D1 that the right edge of the display unit 101 moves toward the rear of the display device 100 is S1 sin θ.

[0028] <Comparison between the first embodiment and the conventional example> 7 and 8 show a display device 600 with a swivel mechanism as a conventional example. The display device 600 includes a display unit 601 and a stand 602 having a support 603 and a stand base 604. In a plan view, the display device 600 has one support 603, which serves as a rotation axis, connected to the center of the left-right direction of the display unit 601. Here, as shown in FIG. 7, half the width of the display unit 601 in the left-right direction is defined as W, the same as that of the display unit 101.

[0029] FIG. 8 illustrates a state in which the display unit 601 of the conventional display device 600 is rotated so that the swivel angle of the display unit 601 is angle θ, similar to the display device 100 of the first embodiment of the present disclosure shown in FIG. 6 . At this time, the distance D2 by which the right edge of the display unit 601 moves rearward from the display device 600 is W·sinθ. Therefore, due to the relationship of W>S1, distance D2>distance D1. That is, even with the same swivel angle as the display device 600 of the conventional display device 600, the distance by which the edge of the display unit 101 moves rearward from the display device 100 is reduced compared to the display device 600 of the conventional display device 600. Therefore, compared to the conventional display device 600 of the first embodiment of the present disclosure, the display device 100 of the first embodiment of the present disclosure can increase the angle at which the display unit 101 can be tilted by the swivel mechanism when the distance from the wall is the same. Furthermore, when the display unit 101 can be tilted to the same swivel angle, it can be installed closer to the wall, thereby increasing the space in the room.

[0030] 3 to 6 illustrate an example in which the display unit 101 is rotated so as to swing to the right. However, when the display unit 101 is rotated so as to swing to the left, the movements in FIGS. 3 to 6 can be performed in the opposite direction, symmetrically with respect to the axis of symmetry 400. For example, when the states in FIGS. 5 and 6 are reversed symmetrically with respect to the axis of symmetry 400, the second insertion portion 220 moves to a position where it abuts against the one end 321, and the first insertion portion 210 moves to the intermediate position 314. At this time, the second insertion portion 220 is engaged between the one end 321 and the locking portion 500. In other words, the side surface 221 of the second insertion portion 220 is sandwiched and engaged between the side wall of the second groove 320 at the one end 321 and the abutting portion 510 of the locking portion 500 so as to contact each other. This allows second insertion portion 220 to rotate around the center of the cross section when viewed from above at one end 321. First insertion portion 210 can slide along second section 315 of first groove 310, which extends downward from midway position 314. Note that in each of the following examples and embodiments, as in embodiment 1, symmetrical movements can be made to rotate display unit 101 so that it faces left.

[0031] The display unit 101 is rotated around the second insertion portion 220 as an axis so as to face leftward, and accordingly, the first insertion portion 210 slides downward along the second section 315. When the display unit 101 is rotated to the maximum angle so as to face leftward, the first insertion portion 210 moves to the position of the other end 312 of the first groove 310.

[0032] It is preferable that the first insertion portion 210 and the second insertion portion 220 have a cylindrical shape. In this case, as shown in Figures 3 to 6, it is possible to smoothly rotate the first insertion portion 210 and the second insertion portion 220 around one end 311 and one end 321. Furthermore, when the first insertion portion 210 and the second insertion portion 220 slide, the contact area with the side walls of the first groove 310 and the side walls of the second groove 320 is always minimized, which reduces frictional resistance and allows for smooth sliding movement.

[0033] In addition, in a plan view, it is preferable that the second section 315 of the first groove 310 is along an arc centered on one end 321 of the second groove 320, and the second section 325 of the second groove 320 is along an arc centered on one end 311 of the first groove 310. For example, in FIG. 6 , the second section 325 is shaped along an arc centered on a center O, which is the center of rotational movement around the first insertion section 210 at one end 311. Furthermore, the second section 315 is shaped along an arc centered on the center of rotational movement around the second insertion section 220 at one end 321. This allows for smooth rotational movement of the display unit 101 around the first insertion section 210 and the second insertion section 220.

[0034] <Modifications of the locking portion of the first embodiment> 9 to 11 are enlarged views of a portion of the first groove 310 of the stand 102 according to a modification of the first embodiment. This modification is characterized in that a leaf spring 530 is used in the locking portion 500, and is otherwise the same as in FIGS. 3 to 5. Note that this modification illustrates the first groove 310, but the same modification can also be used for the second groove 320.

[0035] As shown in Fig. 9, the leaf spring 530 has a mountain-like shape that protrudes toward the inside of the first section 313 of the first groove 310 in a plan view. Similar to Fig. 3, Fig. 9 shows a case where the swivel angle is zero, and the first insertion section 210 is sandwiched between two leaf springs 530 on the left and right. More specifically, inside the first section 313, the two leaf springs 530 abut against the side surfaces 211 of the first insertion section 210 on the left and right, thereby locking the first insertion section 210. Therefore, the leaf spring 530 includes an abutment portion 510.

[0036] 10, like FIG. 4, shows an intermediate stage of moving the first insertion portion 210. The leaf spring 530, which is in the direction in which the first insertion portion 210 slides, elastically deforms itself outward and moves toward the outside of the first section 313. This releases the first insertion portion 210 from the engagement of the leaf spring 530, allowing the first insertion portion 210 to slide. That is, the leaf spring 530 includes the abutting portion 510 and also the elastic portion 520.

[0037] 9 to 11 , for example, the leaf spring 530 preferably has a curved mountain-like shape in a plan view and includes an inclined portion 511 that is inclined relative to the sliding direction of the first insertion portion 210. When the first insertion portion 210 moves and presses the abutting portion 510, the direction of the force applied to the abutting portion 510 is changed by the inclined portion 511 to a force that presses the abutting portion 510 upward, causing the leaf spring 530 to elastically deform outward, and the abutting portion 510 to move outward from the first section 313. Therefore, the locking by the leaf spring 530 can be released only by the force that moves the first insertion portion 210, without applying a separate force that pushes the abutting portion 510 outward from the first section 313.

[0038] 11 shows a state in which the first insertion section 210 has moved to a position where it abuts against the one end 311, similar to FIG. 5. At this time, the first insertion section 210 is locked between the one end 311 and the leaf spring 530. In other words, the side surface 211 of the first insertion section 210 is sandwiched and locked so as to contact the side wall of the first groove 310 at the one end 311 and the abutment portion 510 of the leaf spring 530, respectively. This allows the first insertion section 210 to rotate around the center of the cross section when viewed from above at the position of the one end 311. From this state, similar to FIG. 6 of the first embodiment, the display unit 101 can be rotated left and right to orient the screen in a desired direction.

[0039] <Embodiment 2> Next, a stand 102 and a display device 100 according to a second embodiment of the present disclosure will be described. The stand 102 according to the second embodiment is different from the first embodiment in the shapes of the first groove 310 and the second groove 320 in a plan view, but is otherwise common to the first embodiment. Note that descriptions of the configurations common to the first embodiment will be omitted as appropriate.

[0040] <Details of the swivel function in the second embodiment> 12, 13, 14, and 15 are views of the display device 100 according to the second embodiment as viewed from above. The left, right, upper, and lower sides of FIGS. 12 to 15 correspond to the right, left, rear, and front sides of FIGS. 1 and 2, respectively. A plan view is a viewpoint when the front-to-back and left-to-right directions are considered to be a plane. In addition, in FIGS. 12 to 15, the display unit 101 is shown in a transparent state with its outline indicated by dotted lines, and the first insertion unit 210 and the second insertion unit 220 are shown in cross section as viewed from above. The swivel function according to the second embodiment of the present disclosure will be described in detail below with reference to FIGS. 12 to 15.

[0041] <First Groove and Second Groove of Second Embodiment> 12 , in the stand base 300, the first groove 310 and the second groove 320 are arranged symmetrically with respect to an axis of symmetry 400 extending in the front-to-rear direction in a plan view. The first groove 310 includes a first section 313 extending from one end 311 in a left-to-right direction intersecting the front-to-rear direction to an intermediate position 314, and a second section 315 extending from the intermediate position 314 to the other end 312 and approaching the axis of symmetry 400 as it moves forward from the intermediate position 314. The second groove 320 includes a first section 323 extending from one end 321 in a left-to-right direction intersecting the front-to-rear direction to an intermediate position 324, and a second section 325 extending from the intermediate position 324 to the other end 322 and approaching the axis of symmetry 400 as it moves forward from the intermediate position 324.

[0042] In embodiment 2 of the present disclosure, in a planar view, the midpoint 314 of the first groove 310 is closer to the axis of symmetry 400 than one end 311 of the first groove 310, and the midpoint 324 of the second groove 320 is closer to the axis of symmetry 400 than one end 321 of the second groove 320.

[0043] 12 shows a case where the swivel angle is zero, in which the front surface of the display unit 101 that displays an image faces directly ahead. In this case, the first insertion unit 210 is located between one end 311 and an intermediate position 314 of the first section 313, and the second insertion unit 220 is located between one end 321 and an intermediate position 324 of the first section 323. Furthermore, for example, the first section 313 of the first groove 310 may be provided with two locking portions 500 that protrude inward of the first section 313. Similarly, the first section 323 of the second groove 320 may be provided with two locking portions 500 that protrude inward of the first section 323. As in the first embodiment, the two locking portions 500 can lock the first insertion unit 210 or the second insertion unit 220 by sandwiching them between them from the left and right. More specifically, inside the first section 313, the abutment portions 510 of the two locking portions 500 abut against the side surfaces 211 of the first insertion portion 210 from the left and right, thereby locking the first insertion portion 210. Also, inside the first section 323, the abutment portions 510 of the two locking portions 500 abut against the side surfaces 221 of the second insertion portion 220 from the left and right, thereby locking the second insertion portion 220.

[0044] FIG. 13 shows an intermediate stage before the display unit 101 is rotated so as to swing toward the right. In FIG. 4, the display unit 101 is moved to the right. Accordingly, the first insertion portion 210 moves inside the first section 313 toward the one end 311. The second insertion portion 220 moves inside the first section 323 toward the intermediate position 324. At this time, the elastic portion 520 of the locking portion 500, which is in the direction in which the first insertion portion 210 and the second insertion portion 220 slide, elastically deforms outward, and the abutting portion 510 moves outward of the first section 313 and the first section 323. As a result, the locking of the first insertion portion 210 and the second insertion portion 220 by the locking portion 500 is released, and the first insertion portion 210 and the second insertion portion 220 become slidable. As in the first embodiment, the contact portion 510 may have an inclined portion 511 that is inclined with respect to the direction in which the first insertion portion 210 and the second insertion portion 220 slide in plan view.

[0045] FIG. 14 shows an intermediate stage in which preparation for rotating the display unit 101 is complete. In FIG. 14, the first insertion portion 210 has moved to a position where it abuts against the one end 311, and the second insertion portion 220 has moved to an intermediate position 324. At this time, the first insertion portion 210 is engaged between the one end 311 and the locking portion 500. In other words, the side surface 211 of the first insertion portion 210 is sandwiched and engaged so as to contact the side wall of the first groove 310 at the one end 311 and the abutting portion 510 of the locking portion 500, respectively. This allows the first insertion portion 210 to rotate around the center of the cross section when viewed from above at the one end 311. Furthermore, as shown in FIG. 14, the second insertion portion 220 can slide along the second section 325 of the second groove 320, which extends downward from the intermediate position 324.

[0046] 15 shows a state in which the display unit 101 has been rotated to the maximum angle at which the front surface on which the image is displayed faces rightward. As shown in FIG. 6, the swivel angle at this time is defined as angle θ. The center of rotation about the first insertion section 210 at one end 311 is defined as center O.

[0047] The display unit 101 rotates around the first insertion portion 210 as an axis so as to face the display unit 101 to the right, and in response to this, the second insertion portion 220 slides downward along the second section 325. This allows the display device 100 of the present disclosure to realize a swivel mechanism that rotates the display unit 101 left and right to orient the screen in a desired direction. When the display unit 101 is rotated to the maximum angle towards the right, the second insertion portion 220 moves to the position of the other end 322 of the second groove 320.

[0048] As shown in Fig. 12, half the width of the display unit 101 in the left-right direction is W, and the distance between the right edge of the display unit 101 and the first insertion portion 210 is S2. From Fig. 12, the relationship of W>S2 is established. As shown in Fig. 15, when the swivel angle of the display unit 101 is angle θ, the distance D3 by which the right edge of the display unit 101 moves toward the rear of the display device 100 is S2 sin θ.

[0049] <Comparison between the second embodiment and the conventional example>

[0050] In the display device 600 of the conventional example shown in FIGS. 7 and 8 , when the display unit 601 is rotated so that the swivel angle of the display unit 601 is angle θ, the distance D2 by which the right edge of the display unit 601 moves rearward of the display device 600 is W·sinθ. Therefore, because of the relationship of W>S2, distance D2>distance D3. That is, even with the same swivel angle as the display device 600 of the conventional example, the display device 100 of the second embodiment of the present disclosure has a shorter distance by which the edge of the display unit 101 moves rearward than the display device 600 of the conventional example. Therefore, compared to the conventional example, the display device 100 of the second embodiment of the present disclosure can increase the angle at which the display unit 101 can be tilted by the swivel mechanism when the distance from the wall is the same. Furthermore, when the display unit 101 can be tilted to the same swivel angle, it can be installed closer to the wall to increase the space in the room.

[0051] 12 to 15 illustrate an example in which the display unit 101 is rotated so as to swing to the right. However, when the display unit 101 is rotated so as to swing to the left, the movements in FIGS. 12 to 15 can be performed in the opposite direction, symmetrically with respect to the axis of symmetry 400. For example, when the states in FIGS. 12 and 13 are reversed symmetrically with respect to the axis of symmetry 400, the second insertion portion 220 moves to a position where it abuts against the one end 321, and the first insertion portion 210 moves to the intermediate position 314. At this time, the second insertion portion 220 is engaged between the one end 321 and the locking portion 500. In other words, the side surface 221 of the second insertion portion 220 is sandwiched and engaged between the side wall of the second groove 320 at the one end 321 and the abutting portion 510 of the locking portion 500 so as to contact each other. This allows second insertion portion 220 to rotate about the center of the cross section when viewed from above at one end 321. First insertion portion 210 can slide in second section 315 of first groove 310, which extends downward from midpoint 314.

[0052] The display unit 101 is rotated around the second insertion portion 220 as an axis so as to face leftward, and accordingly, the first insertion portion 210 slides downward along the second section 315. When the display unit 101 is rotated to the maximum angle so as to face leftward, the first insertion portion 210 moves to the position of the other end 312 of the first groove 310.

[0053] The larger the screen size of the display unit 101, the heavier it becomes, and a greater force is required to move it. Therefore, particularly when sliding the display unit 101 left or right, the user performs a pressing operation with the palm of the hand, which is easier to apply force to. In the second embodiment, for example, when moving the display unit 101 as shown in FIGS. 12 to 15, the user faces the display unit 101, places his / her right hand on the left edge of the display unit 101 and pushes it to the right to slide it to the state shown in FIG. 14, and then pulls the left edge of the display unit toward himself / herself with his / her right hand to change the angle, which is a continuous operation. In contrast, in the first embodiment, when moving the display unit 101 as shown in FIGS. 3 to 6, the user faces the display unit 101, places his / her left hand on the right edge of the display unit 101 and pushes it to the left to slide it to the state shown in FIG. 5, and then places his / her right hand on the left edge of the display unit and pulls it toward himself / herself to change the angle, which is a two-step operation. Therefore, the stand 102 and the display device 100 of the second embodiment make it easier for the user to change the swivel angle of the display unit 101 compared to the first embodiment.

[0054] <Embodiment 3> Next, a stand 102 and a display device 100 according to a third embodiment of the present disclosure will be described. The stand 102 according to the third embodiment is different from that according to the first embodiment in the shapes of the first insertion portion 210 and the second insertion portion 220 and the shapes of the first groove 310 and the second groove 320 in a plan view, but is otherwise common to the first embodiment. Note that a description of the configuration common to the first embodiment will be omitted as appropriate.

[0055] 16, 17, 18, and 19 are views of the display device 100 according to the third embodiment as viewed from above. The left, right, upper, and lower sides of FIGS. 16 to 19 correspond to the right, left, rear, and front sides of FIGS. 1 and 2, respectively. A plan view is a viewpoint when the front-rear and left-right directions are considered to be a plane. In addition, in FIGS. 16 to 19, the display unit 101 is shown in a transparent state with its outline indicated by a dotted line, and the first insertion unit 210 and the second insertion unit 220 are shown in cross section as viewed from above.

[0056] 16, the cross section of the first insertion portion 210 and the second insertion portion 220 when viewed from above has an elliptical shape that is long in the front-to-rear direction. Furthermore, in the stand base 300, the first groove 310 and the second groove 320 are provided symmetrically with respect to an axis of symmetry 400 that extends in the front-to-rear direction in a plan view. The first section 313 of the first groove 310 and the first section 323 of the second groove 320 have a larger width in the front-to-rear direction than in the first embodiment so that the elliptical first insertion portion 210 and the second insertion portion 220 can slide in the left-to-right direction.

[0057] 16 to 19, the first insertion portion 210 is slidably inserted into the first groove 310. In other words, the first insertion portion 210 inserted into the first groove 310 can slide along the first groove 310. The second insertion portion 220 is slidably inserted into the second groove 320. In other words, the second insertion portion 220 inserted into the second groove 320 can slide along the second groove 320.

[0058] 16 to 19, in first section 313 and first section 323, the side walls at positions between one end 311 and midway position 314 and between one end 321 and midway position 324 in plan view may be shaped to be partially deformed toward the rear. This makes first insertion portion 210 and second insertion portion 220 slidable in the left-right direction, and allows first insertion portion 210 and second insertion portion 220 to be locked at desired positions without providing locking portion 500 of embodiment 1.

[0059] 16 shows a case where the swivel angle is zero, that is, the front surface of the display unit 101 that displays an image faces directly ahead. In this case, the first insertion section 210 is located at a position between one end 311 and an intermediate position 314 in the first section 313, and the second insertion section 220 is located at a position between one end 321 and an intermediate position 324 in the first section 323.

[0060] FIG. 17 shows an intermediate stage in which preparation for rotating the display unit 101 is complete. In FIG. 17, the first insertion portion 210 has moved to a position where it abuts against one end 311, and the second insertion portion 220 has moved to an intermediate position 324. This allows the first insertion portion 210 to rotate around the first insertion portion 210 as the rotation axis at the one end 311. Also, as shown in FIG. 17, the second insertion portion 220 can slide along the second section 325 of the second groove 320, which extends downward from the intermediate position 324. For example, it is preferable that the front-to-rear and left-to-right widths of the first section 313 at the one end 311 and the first section 323 at the one end 321 are larger than the cross-sectional sizes of the first insertion portion 210 and the second insertion portion 220 in a plan view. 17, for example, a space can be secured between the side surface 211 of the first insertion portion 210 and the side wall of the first section 313 in a plan view, allowing the first insertion portion 210 to rotate. Furthermore, it is preferable that the side walls of one end 311 and one end 321 are curved in a plan view so as to match the trajectory of rotation about the first insertion portion 210 and the second insertion portion 220, which have oval cross sections that are long in the front-to-rear direction. By doing so, the first insertion portion 210 and the second insertion portion 220 can rotate without resistance at the positions of the one end 311 and one end 321, achieving a swivel mechanism with smooth movement.

[0061] Figure 18 shows the state in which the front surface of the display unit 101 on which the image is displayed is rotated toward the right, and Figure 19 shows the state in which the front surface of the display unit 101 on which the image is displayed is rotated toward the right to the maximum angle that it can be rotated.

[0062] 18 and 19 , the display unit 101 is rotated around the first insertion portion 210 as an axis so as to face the right side, and accordingly, the second insertion portion 220 slides downward along the second section 325. In this way, the display device 100 of the present disclosure realizes a swivel mechanism that rotates the display unit 101 left and right to orient the screen in a desired direction. When the display unit 101 is rotated to the maximum angle toward the right side, the second insertion portion 220 moves to the position of the other end 322 of the second groove 320. Note that the left and right widths of the second section 315 and the second section 325 are preferably larger than the left and right widths of the first insertion portion 210 and the second insertion portion 220 in a plan view. In this way, for example, in FIG. 18, in a plan view, space can be secured between the side surface 221 of the second insertion portion 220 and the side wall of the second section 325, allowing the second insertion portion 220 to slide smoothly inside the second section 325.

[0063] 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 the same as 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.
