Description

[Technical Field]

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

[0002] Patent Document 1 discloses a stand. The stand supports a display device. In the stand, a stand support is connected to the display device and a stand base. A connecting rod is connected to the movable base. The connecting rod is inserted into the stand base and is slidable. When the stand is installed away from a wall, the movable base is sufficiently extended from the stand toward the rear of the display device. When the stand is installed close to the wall, the amount of protrusion of the movable base toward the rear of the display device is reduced. The movable base is pushed toward the rear of the display device by a compression coil spring (paragraphs 0017, 0021, 0022, and 0027 and figures 1 to 5). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-34179 Summary of the Invention [Problem to be solved by the invention]

[0004] In the stand disclosed in Patent Document 1, when the stand is installed away from a wall and tilted backward, the rear end of the movable base remains in contact with the floor, while the stand base and the movable base other than the rear end are raised, and a force that compresses the compression coil spring is applied to the movable base. This may cause the compression coil spring to compress, reducing the amount of protrusion of the movable base toward the rear of the display device. This may cause the center of gravity of the display device to become unstable, potentially causing the stand to tip over.

[0005] In view of this problem, an aspect of the present disclosure provides a stand and a display device that can be installed either away from a wall surface or close to the wall surface and that can be prevented from tipping over. [Means for solving the problem]

[0006] A stand of a first aspect of the present disclosure comprises a foot having a connecting portion, a support to which the connecting portion is connected and which guides the connecting portion along a path from a first end to a second end higher than the first end, and a stopper that does not hinder movement of the connecting portion along the path when the support has a first posture, and that hinders movement of the connecting portion along the path when the support has a second posture tilted from the first posture.

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

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0010] 1. First embodiment 1.1 Display device Fig. 1 is a perspective view that schematically illustrates a display device according to the first embodiment, and also includes arrows that indicate the up-down, left-right, and front-rear directions of the display device according to the first embodiment.

[0011] 1 is placed on a floor. When the floor is a horizontal plane, the left-right and front-rear directions of the display device 1 are horizontal, and the up-down direction of the display device 1 is vertical.

[0012] As shown in FIG. 1, the display device 1 includes a stand 11 and a display 12 .

[0013] The stand 11 supports the display 12. The stand 11 is placed on the floor and supports the display 12 above the floor. The stand 11 supports the display 12 so that the up-down, left-right, and front-to-back directions of the display 12 respectively match the up-down, left-right, and front-to-back directions of the display device 1. The up-down direction of the display 12 may be tilted from the up-down direction of the display device 1. The left-to-right direction of the display 12 may be tilted from the left-to-right direction of the display device 1. The front-to-back direction of the display 12 may be tilted from the front-to-back direction of the display device 1.

[0014] The display 12 is a television receiver. Therefore, the display 12 displays a video according to a video signal included in the input received wave, and outputs a sound according to an audio signal included in the input received wave. The display 12 may be a display other than a television receiver. For example, the display 12 may be a monitor for a personal computer, digital signage, or the like.

[0015] 1.2 Stand As shown in FIG. 1, the stand 11 includes a base 21, a first support 22, a second support 23, a first leg 24, a second leg 25, a first link 26, and a second link 27.

[0016] The stand 11 has two supports, a first support 22 and a second support 23, two legs, a first leg 24 and a second leg 25, and two links, a first link 26 and a second link 27. The number of supports, legs, and links provided on the stand 11 may be increased or decreased from two.

[0017] The base 21 is placed on the floor surface and is parallel to the floor surface. The base 21 has a rectangular plate shape. The base 21 may have a plate shape other than a rectangular plate shape. The base 21 may have a shape other than a plate shape.

[0018] The lower ends of the first support column 22 and the second support column 23 are connected to the rear end of the base 21. As a result, the first support column 22 and the second support column 23 are supported by the base 21. When supported by the base 21 that is parallel to the floor surface, the first support column 22 and the second support column 23 extend in the vertical direction. In this state, the first support column 22 and the second support column 23 may extend in a direction inclined from the vertical direction.

[0019] When a force that tilts the display device 1 forward is applied to the display device 1, a force that presses the front end of the base 21 against the floor surface is applied to the base 21. Therefore, the base 21 prevents the display device 1 from tilting forward. However, when a force that tilts the display device 1 backward is applied to the display device 1, a force that lifts the front end of the base 21 from the floor surface is applied to the base 21. Therefore, the base 21 does not prevent the display device 1 from tilting backward.

[0020] The upper ends of the first support column 22 and the second support column 23 are coupled to the display 12. In this way, the first support column 22 and the second support column 23 support the display 12.

[0021] The first support column 22 and the second support column 23 are spaced apart from each other in the left-right direction.

[0022] The first foot 24 and the second foot 25 have a flat bar shape. The first foot 24 and the second foot 25 may have a bar shape other than a flat bar shape. One end of the first foot 24 and the second foot 25 is connected to the middle of the first support column 22 and the second support column 23, respectively. The other end of the first foot 24 and the second foot 25 is in contact with the floor surface. The other end of the first foot 24 and the second foot 25 is located rearward of one end of the first foot 24 and the second foot 25, respectively, and is located lower than one end of the first foot 24 and the second foot 25, respectively. The other end of the first foot 24 and the second foot 25 is located rearward of the first support column 22 and the second support column 23, respectively.

[0023] When a force that tilts the display device 1 backward is applied to the display device 1 while the connection state of the first leg 24 to the first support column 22 and the connection state of the second leg 25 to the second support column 23 remain unchanged, a force that presses the other ends of the first leg 24 and the second leg 25 against the floor surface is applied to the first leg 24 and the second leg 25. Therefore, the first leg 24 and the second leg 25 prevent the display device 1 from tilting backward. However, when a force that tilts the display device 1 forward is applied to the display device 1, a force that lifts the other ends of the first leg 24 and the second leg 25 off the floor surface is applied to the first leg 24 and the second leg 25. Therefore, the first leg 24 and the second leg 25 do not prevent the display device 1 from tilting forward.

[0024] Therefore, the base 21, the first leg 24 and the second leg 25 cooperate to prevent the display device 1 from tilting forward or backward.

[0025] The first link 26 and the second link 27 have a flat bar shape. The first link 26 and the second link 27 may have a bar shape other than a flat bar shape. One end of the first link 26 and the second link 27 is connected to the lower end of the first support column 22 and the second support column 23, respectively. The other end of the first link 26 and the second link 27 is connected to the middle of the first leg 24 and the second leg 25.

[0026] When the connected position of the first support 22 to which one end of the first leg 24 is connected and the connected position of the first support 22 to which one end of the second leg 25 is connected do not change, the first link 26 and the second link 27 regulate the angle between the first leg 24 and the first support 22 and the angle between the second leg 25 and the second support 23 from changing.

[0027] The second support 23, the second leg 25, and the second link 27 have structures similar to those of the first support 22, the first leg 24, and the first link 26. For this reason, the following will only describe the first support 22, the first leg 24, and the first link 26 and the members associated therewith, and will omit redundant descriptions of the second support 23, the second leg 25, the second link 27, and the members associated therewith.

[0028] 1.3 Spreading and narrowing of the legs Fig. 2A is a side view schematically illustrating the display device of the first embodiment installed away from a wall surface. Fig. 2B is a side view schematically illustrating the display device of the first embodiment installed close to a wall surface. Figs. 2A and 2B also illustrate arrows indicating the up-down and front-back directions of the display device of the first embodiment.

[0029] As shown in FIGS. 2A and 2B, one end of the first leg 24 includes a connecting portion 31 .

[0030] The connecting portion 31 is connected to the middle portion of the first support pillar 22. The connecting portion 31 is connected to the first support pillar 22 so as to be rotatable about a rotation axis parallel to the left-right direction. Therefore, the connecting portion 31 is connected to the first support pillar 22 so that the angle θ between the first leg 24 and the first support pillar 22 can be changed. As shown in FIG. 2A, when the angle θ increases, the front-rear distance L from one end of the first leg 24 and the first support pillar 22 to the other end of the first leg 24 increases, and the first leg 24 widens. On the other hand, as shown in FIG. 2B, when the angle θ decreases, the front-rear distance L decreases, and the first leg 24 narrows.

[0031] A slit 22a is formed in the first support 22. The connecting portion 31 includes a shaft 41. The shaft 41 is inserted into the slit 22a. The shaft 41 is movable in a direction parallel to the longitudinal direction of the slit 22a. As a result, the first support 22 guides the shaft 41 along a path 61 parallel to the longitudinal direction of the slit 22a. The path 61 extends from the first end 62 to the second end 63. The longitudinal direction of the slit 22a is parallel to the extension direction of the first support 22 and parallel to the up-down direction. The longitudinal direction of the slit 22a may be parallel to a direction inclined from the extension direction of the first support 22, or may be parallel to a direction inclined from the up-down direction. The shaft 41 extends in the left-right direction. The shaft 41 may extend in a direction inclined from the left-right direction. The second end 63 is located higher than the first end 62 and is farther from the floor surface 201 than the first end 62. The shaft 41 is rotatable relative to the first support column 22 about a rotation axis parallel to the left-right direction. As a result, as shown in FIG. 2A , as the shaft 41 approaches the first end 62, the angle θ between the first leg 24 and the first support column 22 increases, and the distance L in the front-to-rear direction from one end of the first leg 24 and the first support column 22 to the other end of the first leg 24 increases, causing the first leg 24 to widen. Furthermore, as shown in FIG. 2B , as the connecting portion 31 moves away from the first end 62, the angle θ decreases, the distance L in the front-to-rear direction decreases, and the first leg 24 narrows. The first support 22 may guide the connecting portion 31 along the path 61 by a method other than moving the shaft 41 provided on the connecting portion 31 in the longitudinal direction of the slit 22a formed in the first support 22. For example, the first support 22 may guide the connecting portion 31 along the path 61 by sliding the ring provided on the connecting portion 31 along a pipe provided on the first support 22 and passing through the link.

[0032] Shaft 41 has a columnar or cylindrical shape. Therefore, the outer circumferential surface of shaft 41 is a circumferential surface. When viewed from the left or right, the circumferential surface may have a circular or elliptical shape.

[0033] One end of the first link 26 is connected to the lower end of the first support column 22 so as to be rotatable about an axis of rotation parallel to the left-right direction. The other end of the first link 26 is connected to the middle of the first foot 24 so as to be rotatable about an axis of rotation parallel to the left-right direction.

[0034] As shown in FIGS. 2A and 2B, the stand 11 includes a torsion spring 28.

[0035] One end of the torsion spring 28 is coupled to the first leg 24. The other end of the torsion spring 28 is coupled to the first link 26. The torsion spring 28 applies an elastic force to the first leg 24 and the first link 26 in a direction that increases the angle θ between the first leg 24 and the first link 26 and lengthens the distance L in the front-to-rear direction from the one end of the first leg 24 and the first support 22 to the other end of the first leg 24. Therefore, as shown in FIG. 2A , when the other end of the first leg 24 does not abut against the wall surface 202, the connecting portion 31 is positioned at the first end 62, the angle θ is at its maximum, the distance L in the front-to-rear direction is at its longest, and the width of the first leg 24 is at its maximum. 2B , when the other end of first leg 24 abuts against wall surface 202, connecting portion 31 is positioned closer to second end 63 than first end 62, angle θ is smaller than the maximum angle, front-to-rear distance L is shorter than the maximum distance, and the spread of first leg 24 is narrower than the maximum spread. Torsion spring 28 may be replaced with a spring other than torsion spring 28. For example, torsion spring 28 may be replaced with a compression spring or tension spring. One end of the compression spring or tension spring is connected to first support post 22. The other end of the compression spring or tension spring is connected to shaft 41. The compression spring or tension spring applies an elastic force to first support post 22 and shaft 41 in a direction that moves shaft 41 closer to first end 62.

[0036] 1.4 Stoppers to prevent tipping 2C is a side view schematically illustrating the display device of the first embodiment in a state where it is installed away from a wall surface and tilted backward, and also includes arrows indicating the up-down and front-back directions of the display device of the first embodiment.

[0037] 2A, in a state in which base 21 is parallel to floor surface 201, first support column 22 has a first posture in which it extends in the vertical direction, and the longitudinal direction of slit 22a is parallel to the vertical direction. In a state in which the front end of base 21 is lifted off floor surface 201, in which first support column 22 has a second posture in which it extends in a direction inclined rearward from the vertical direction, and the longitudinal direction of slit 22a is parallel to the direction inclined from the vertical direction.

[0038] As shown in FIGS. 2A to 2C, the stand 11 includes a stopper 29.

[0039] Stopper 29 is suspended from first support column 22. Stopper 29 is supported by first support column 22 so as to be rotatable about a rotation axis parallel to the left-right direction. Therefore, stopper 29 maintains a constant posture due to its own weight, whether first support column 22 is in the first posture or the second posture.

[0040] As shown in FIGS. 2A and 2B , the entire stopper 29 is positioned outside the path 61 when the first support column 22 has the first posture. As shown in FIG. 2C , at least a portion of the stopper 29 is positioned within the path 61 when the first support column 22 has the second posture. As a result, the stopper 29 does not inhibit the movement of the shaft 41 along the path 61 when the first support column 22 has the first posture. As a result, when the display device 1 is not tilted, the first legs 24 can be spread and also contracted. As a result, when the display device 1 is not tilted, the display device 1 can be installed away from the wall surface 202, and the display device 1 can also be installed without being separated from the wall surface 202. Furthermore, when the first support column 22 has the second posture, the stopper 29 abuts against the shaft 41 attempting to move along the path 61, inhibiting the shaft 41 from moving along the path 61. As a result, when the display device 1 is tilted backward, the first leg 24 cannot be retracted. As a result, when the display device 1 is tilted backward, the first leg 24 retracts, preventing the display device 1 from further tilting backward. At least a portion of the stopper 29 is disposed within the path 61 and prevents the shaft 41 from moving along the path 61, for example, when the first support column 22 is tilted by 10° or more.

[0041] FIG. 3 is a side view schematically illustrating a state in which the display device of the reference example is installed away from a wall surface and tilted backward.

[0042] A display device 9 of the reference example shown in FIG. 3 differs from the display device 1 of the first embodiment in that it does not include a stopper 29.

[0043] 3, when a force that tilts the display device 9 of the reference example backward is applied to the display device 9 of the reference example, the axis 41 moves away from the first end 62, and the distance L in the front-to-rear direction from one end of the first leg 24 and the first support 22 to the other end of the first leg 24 becomes shorter. As a result, the center of gravity of the display 12 may not be able to maintain a stable state, and the display device 9 of the reference example may not be able to be prevented from tipping over.

[0044] 2C, when a force that tilts the display device 1 of the first embodiment backward is applied to the display device 1 of the first embodiment, the axis 41 remains at the first end 62, and the distance L in the front-to-rear direction from one end of the first leg 24 and the first support column 22 to the other end of the first leg 24 is maintained. This allows the center of gravity of the display 12 to remain stable, and makes it possible to prevent the display device 1 of the first embodiment from tipping over.

[0045] 1.5 Stopper structure Fig. 4A is an enlarged side view of a first support column, a first leg, and a stopper of a stand provided in the display device of the first embodiment, the first support column being in a first position. Fig. 4B is an enlarged side view of a first support column, a first leg, and a stopper of a stand provided in the display device of the first embodiment, the first support column being in a second position. Figs. 4A and 4B also show arrows indicating the up-down and front-back directions of the display device of the first embodiment.

[0046] 4A and 4B, stopper 29 is disposed forward of slit 22a. Stopper 29 is supported by first support column 22 so as to be rotatable about rotation axis 29c that is parallel to the left-right direction. When viewed from the left or right, stopper 29 has a trapezoidal shape whose size in the front-to-rear direction increases downward.

[0047] As shown in FIGS. 4A and 4B, the stopper 29 includes a supported portion 81, a center of gravity portion 82, and a blocking portion 83.

[0048] The supported portion 81 is supported by the first support column 22 so as to be rotatable about a rotation axis 29c that is parallel to the left-right direction. This allows the stopper 29 to rotate about the rotation axis 29c relative to the first support column 22. This allows the center of gravity portion 82 and the blocking portion 83 to rotate about the rotation axis 29c relative to the first support column 22.

[0049] The center of gravity 82 has a center of gravity 29g of the stopper 29. Because the center of gravity 82 is rotatable relative to the first support column 22 around the rotation axis 29c, the center of gravity 29g is disposed below the rotation axis 29c. Therefore, the center of gravity 82 extends downward from the supported column 81. The state in which the center of gravity 29g is disposed below the rotation axis 29c and the center of gravity 82 extends downward from the supported column 81 is maintained both when the first support column 22 has the first posture and when the first support column 22 has the second posture.

[0050] As a result, the supported portion 81 and the center of gravity portion 82 constitute a maintaining mechanism 91 that maintains the stopper 29 in a constant attitude both when the first support column 22 has the first attitude and when the first support column 22 has the second attitude. The constant attitude that is maintained is an attitude in which the center of gravity 29g of the stopper 29 is positioned vertically below the rotation axis 29c, and the center of gravity portion 82 hangs down vertically from the supported portion 81.

[0051] The blocking portion 83 is located at the lower end of the stopper 29. The vertical distance from the rotation shaft 29c to the blocking portion 83 is sufficiently longer than the front-to-rear distance from the rotation shaft 29c to the path 61. The front-to-rear distance from the rotation shaft 29c to the rearmost end of the blocking portion 83 is shorter than the front-to-rear distance from the rotation shaft 29c to the path 61. As a result, the blocking portion 83 is located outside the path 61 when the first support column 22 has the first posture. Furthermore, the blocking portion 83 is located inside the path 61 when the first support column 22 has the second posture. As a result, when the first support column 22 has the second posture, the blocking portion 83 abuts against the shaft 41 attempting to move along the path 61, and inhibits the shaft 41 from moving along the path 61.

[0052] When the blocking portion 83 is disposed in the path 61, it is disposed along the axis 41 disposed at the first end 62. As a result, the blocking portion 83 abuts against the axis 41 that tends to move away from the first end 62, and keeps the axis 41 near the first end 62.

[0053] The blocking portion 83 is located below the supported portion 81. Therefore, the blocking portion 83 has a bottom surface 83a facing downward. When the blocking portion 83 is placed in the path 61, the bottom surface 83a abuts against the shaft 41. The bottom surface 83a is flat. The bottom surface 83a is horizontal.

[0054] 1.6 Variations Fig. 5A is an enlarged side view schematically illustrating a first support column, a first leg, and a stopper of a stand provided in a display device of a first modified example of the first embodiment, in a state where the first support column has a first posture. Fig. 5B is an enlarged side view schematically illustrating a first support column, a first leg, and a stopper of a stand provided in a display device of a first modified example of the first embodiment, in a state where the first support column has a second posture. Figs. 5A and 5B also illustrate arrows indicating the up-down direction and the front-back direction of the display device of the first modified example of the first embodiment.

[0055] In the first variant of the first embodiment, as shown in Figures 5A and 5B, when viewed from the left or right, the stopper 29 has a rectangular shape whose front-to-rear size does not change even when moved downward.

[0056] In a first modified example of the first embodiment, the bottom surface 83a of the blocking portion 83 is an arcuate surface centered on the rotation axis 29c. When the bottom surface 83a is an arcuate surface, the central portion of the bottom surface 83a protrudes toward the first end portion 62, and the distance that the shaft 41 moving away from the first end portion 62 moves before it abuts on the blocking portion 83 is shortened, compared to when the bottom surface 83a is a flat surface. Furthermore, when the bottom surface 83a is an arcuate surface, it is possible to prevent the distance from changing due to a change in the angle of inclination of the first support column 22.

[0057] Fig. 6A is an enlarged side view schematically illustrating a first support column, a first leg, and a stopper of a stand provided in a display device of a second modified example of the first embodiment, in a state where the first support column has a first posture. Fig. 6B is an enlarged side view schematically illustrating a first support column, a first leg, and a stopper of a stand provided in a display device of a second modified example of the first embodiment, in a state where the first support column has a second posture. Figs. 6A and 6B also illustrate arrows indicating the up-down direction and the front-back direction of the display device of the second modified example of the first embodiment.

[0058] In the second variant of the first embodiment, as shown in Figures 6A and 6B, when viewed from the left or right, the stopper 29 has a rectangular shape whose front-to-rear size does not change even when moved downward.

[0059] In the second modified example of the first embodiment, the bottom surface 83a of the blocking portion 83 is concave. The concave surface curves in the same direction as the curved outer circumferential surface of the shaft 41, and has a radius of curvature equal to or greater than the radius of curvature of the outer circumferential surface of the shaft 41. This makes it easier for the shaft 41 to remain in the recess formed by the bottom surface 83a when the bottom surface 83a abuts against the shaft 41. This makes it possible to stably prevent the shaft 41 from moving along the path 61. Desirably, the concave surface has a radius of curvature approximately the same as the radius of curvature of the outer circumferential surface of the shaft 41. This makes it possible for the convex surface included in the outer circumferential surface of the shaft 41 to come into contact with the concave surface when the concave surface abuts against the shaft 41.

[0060] Fig. 7A is an enlarged side view schematically illustrating a first support column, a first leg, and a stopper of a stand provided in a display device of a third modified example of the first embodiment, in a state where the first support column has a first position. Fig. 7B is an enlarged side view schematically illustrating a first support column, a first leg, and a stopper of a stand provided in a display device of a third modified example of the first embodiment, in a state where the first support column has a second position. Figs. 7A and 7B also illustrate arrows indicating the up-down direction and the front-back direction of the display device of the third modified example of the first embodiment.

[0061] In the third variant of the first embodiment, as shown in Figures 7A and 7B, the stopper 29 has a rectangular shape when viewed from the left or right, and its front-to-rear size does not change even when it moves downward.

[0062] In the third modified example of the first embodiment, similarly to the first modified example of the first embodiment, the bottom surface 83a of the blocking portion 83 is an arcuate surface centered on the rotation axis 29c.

[0063] In the third modified example of the first embodiment, the outer peripheral surface of the shaft 41 includes a surface 41a that becomes a second arcuate surface when the above-described arcuate surface is defined as a first arcuate surface. The surface 41a curves in the same direction as the curve of the bottom surface 83a of the blocking portion 83, and has a radius of curvature that is approximately the same as the radius of curvature of the bottom surface 83a of the blocking portion 83. As a result, when the bottom surface 83a of the blocking portion 83 abuts against the shaft 41, the surface 41a of the shaft 41 comes into contact with the bottom surface 83a of the blocking portion 83. This brings the shaft 41 and the blocking portion 83 into surface contact with each other. This makes it possible to stably inhibit the shaft 41 from moving along the path 61.

[0064] Fig. 8A is an enlarged side view schematically illustrating a state in which the first support pillar has a first posture, of the first support pillar, a first leg, and a stopper of the stand provided in the display device of the fourth modified example of the first embodiment. Fig. 8B is an enlarged side view schematically illustrating a state in which the first support pillar has a second posture, of the first support pillar, a first leg, and a stopper of the stand provided in the display device of the fourth modified example of the first embodiment. Figs. 8A and 8B also depict arrows indicating the up-down direction and the front-back direction of the display device of the fourth modified example of the first embodiment.

[0065] In the fourth variant of the first embodiment, as shown in Figures 8A and 8B, when viewed from the left or right, the stopper 29 has a rectangular shape whose front-to-rear size does not change even when moved downward.

[0066] In the fourth modification of the first embodiment, the blocking portion 83 has a side surface 83b facing rearward. The side surface 83b abuts against the shaft 41 when the blocking portion 83 is disposed in the path 61.

[0067] In the fourth modified example of the first embodiment, a V-shaped groove is formed in shaft 41. As a result, the outer peripheral surface of shaft 41 includes a first surface 41b and a second surface 41c that define the V-shaped groove. When a bottom surface 83a and a side surface 83b of blocking portion 83 abut against shaft 41, first surface 41b and second surface 41c come into contact with bottom surface 83a and side surface 83b, respectively. As a result, movement of shaft 41 along path 61 can be stably inhibited.

[0068] 2. Second embodiment The following describes the differences between the second embodiment and the first embodiment. For points that are not described, the second embodiment also employs the same configuration as that employed in the first embodiment.

[0069] Fig. 9A is an enlarged side view of a first support column, a first leg, and a stopper of a stand provided in a display device of the second embodiment, the first support column being in a first position. Fig. 9B is an enlarged side view of a first support column, a first leg, and a stopper of a stand provided in a display device of the second embodiment, the first support column being in a second position. Figs. 9A and 9B also show arrows indicating the up-down and front-back directions of the display device of the second embodiment.

[0070] 9A and 9B, in the second embodiment, the blocking portion 83 is located at the upper end of the stopper 29. The blocking portion 83 is located outside the path 61 when the first support column 22 has the first posture. The blocking portion 83 is located inside the path 61 when the first support column 22 has the second posture. As a result, when the first support column 22 has the second posture, the blocking portion 83 comes into contact with the shaft 41 attempting to move along the path 61, and inhibits the shaft 41 from moving along the path 61.

[0071] The blocking portion 83 is located above the supported portion 81. The blocking portion 83 is separated upward from the supported portion 81 across a gap 101 that can accommodate the shaft 41. Therefore, the blocking portion 83 has an abutment surface 83c that faces the gap 101 and faces downward. The abutment surface 83c abuts against the shaft 41 when the blocking portion 83 is placed in the path 61.

[0072] As shown in FIGS. 9A and 9B, the stopper 29 includes a connecting portion 84 .

[0073] One end of the connecting portion 84 is connected to the supported portion 81. The other end of the connecting portion 84 is connected to the rear end of the interrupting portion 83. As a result, the connecting portion 84 connects the interrupting portion 83 to the supported portion 81. The interrupting portion 83 and the connecting portion 84 connected to each other form a structure having a hook shape. A gap 101 that opens forward is formed in the formed structure. The stopper 29 is positioned rearward of the slit 22a. As a result, when the posture of the first support 22 changes from the first posture to the second posture, the shaft 41 enters the gap 101 through the open portion. As a result, the abutment surface 83c of the interrupting portion 83 abuts against the shaft 41.

[0074] In the stopper 29 provided in the display device 1 of the first embodiment, the blocking portion 83 is located below the supported portion 81, and the shaft 41 abuts against the blocking portion 83 from below. Therefore, when the shaft 41 abuts against the blocking portion 83, the stopper 29 may rotate, causing the blocking portion 83 to move forward or backward.

[0075] In contrast, in the stopper 29 provided in the display device of the second embodiment, the blocking portion 83 is located above the supported portion 81, and the shaft 41 abuts against the blocking portion 83 from below. Therefore, when the shaft 41 abuts against the blocking portion 83, the stopper 29 rotates, preventing the blocking portion 83 from moving forward or backward. Therefore, movement of the shaft 41 along the path 61 can be stably prevented.

[0076] The present disclosure is not limited to the above-described embodiments, and may be replaced with a configuration that is substantially the same as the configuration shown in the above-described embodiments, a configuration that has the same effect, or a configuration that can achieve the same purpose.
