Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in consideration of the environment, it is required to reduce the amount of packing materials used and discarded. As the reduction of packing materials progresses in the packing of display devices, there is a risk that the amount of members sufficient to prepare a packing case capable of holding the stand and the support column as in Patent Document 1 cannot be secured. The present disclosure provides a stand that is easy to assemble and a display device supported by the stand by enabling the parts constituting the stand to hold each other in proper positions only by themselves when assembling the stand.

[0008] The embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to these embodiments and modifications. Various modifications are possible, other than those described herein, as long as they do not depart from the technical spirit of the present disclosure, depending on the design and other factors.

[0009] [Embodiment 1] Figure 1 is a schematic diagram of a display device 1 according to Embodiment 1. The display device 1 is a display device capable of displaying images such as videos and still images. Examples of such display devices include, but are not limited to, a television receiver or a monitor used in a personal computer.

[0010] [Display device] The display device 1 comprises a display unit 11 and a stand 21. The display unit 11 has a rectangular plate shape. The display unit 11 has a housing 13 and a display panel 15 to which the housing 13 is attached. Examples of the display panel 15 include a liquid crystal panel, an OLED (Organic Light Emitting Diode) display panel, a QLED (Quantum dot Light Emitting Diode) display panel, etc. The type of display panel 15 is not particularly limited as long as it can display an image. The stand 21 is placed on the mounting surface with its bottom surface facing downwards. The stand 21 is connected to the housing 13 of the display unit 11. The stand 21 supports the display unit 11 and holds the display unit 11 above the mounting surface.

[0011] [stand] FIG. 2 is a schematic view of the stand 21 according to Embodiment 1 as seen from the upper surface side. FIG. 3 is a schematic view of the stand 21 according to Embodiment 1 as seen from the bottom surface side. The stand 21 has a support column 23, a stand base 25, and a screw 27. The stand base 25 has a stand cover 251, a stand base 253, and a support column fixing member 255. The support column 23 is inserted into the stand cover 251 from the upper surface side of the stand base 25. Although details will be described later, the support column 23 is fixed to the stand base 25 from the bottom surface side of the stand base 25 by the screw 27.

[0012] [Support column] FIG. 4 is a perspective cross-sectional view of a part of the support column 23 cut. Specifically, a part of the support column 23 in FIG. 2 is cut along the length direction. The support column 23 is a long bar-shaped structure. The support column 23 can be formed of, for example, a resin material or a metal material. In the present embodiment, the support column 23 is a bar-shaped member having a channel-shaped cross section, but may be, for example, a bar-shaped member having an L-shaped cross section, a square pipe, or a solid square bar. A predetermined portion at one end of the support column 23 is defined as an end portion 237. Although details will be described later, the end portion 237 is a portion to be inserted into the support column insertion portion 2513 of the stand cover 251. The other end of the support column 23 on the side opposite to the end portion 237 is connected to the housing 13 of the display unit 11.

[0013] The end portion 237 includes a bottom portion 231, side portions 233, and a locked portion 235 provided on the side portions 233. In the present embodiment, the bottom portion 231 and the side portions 233 are plate-shaped parts, and are a bottom plate and side plates, respectively. The lower surface of the bottom portion 231 is a surface having a normal line parallel to the length direction of the support column 23. A screw hole 2311 is provided in the bottom portion 231. In the present embodiment, a plurality of screw holes 2311 are provided, but the number of screw holes 2311 can be arbitrarily set as long as it is one or more.

[0014] The side surface of the side part 233 is a surface having a normal perpendicular to the longitudinal direction of the support column 23. A locked part 235 is provided on the side part 233. The locked part 235 is a part to be locked by the claw part 2515 of the stand cover 251 described later. In the present embodiment, the locked part 235 is a hole formed in the plate-shaped side part 233. Note that when the support column 23 is a solid square bar, the locked part 235 may be a recess formed by denting a part of the side part 233.

[0015] [Stand cover] FIG. 4 is a perspective cross-sectional view of a part of the stand cover 251 according to Embodiment 1. Specifically, a part of the stand cover 251 in FIG. 2 is cut along a direction intersecting the longitudinal direction. The stand cover 251 is a member constituting the upper side of the stand base 25. The stand cover 251 can be formed of, for example, a resin material. An insertion port 2511, which is a generally rectangular opening, is formed on the upper surface of the stand cover 251. The stand cover 251 has a support column insertion part 2513 as a hole having the insertion port 2511 as an entrance and the inner wall 2517 as an inner side surface.

[0016] The one end part 237 can be inserted into the inside of the stand cover 251 from the insertion port 2511 formed on the upper surface of the stand cover 251 by the support column insertion part 2513. In a plan view, the shape of the insertion port 2511 conforms to the shape of the cross-section of the one end part 237. In the present embodiment, the shape of the insertion port 2511 is made generally rectangular in accordance with the support column 23 having a channel-shaped cross-section. Thereby, the wobbling of the support column 23 inserted into the support column insertion part 2513 can be suppressed.

[0017] A claw portion 2515 is provided on the inside of the support column insertion portion 2513. The claw portion 2515 is provided on the inner circumferential surface of the support column insertion portion 2513, on the surface facing the side portion 233 of the support column 23 when one end portion 237 is inserted into the support column insertion portion 2513. As will be described in detail later, when one end portion 237 is inserted into the support column insertion portion 2513 and the bottom portion 231 comes into contact with the contact portion 2551 of the support column fixing member 255, which will be described later, the claw portion 2515 locks the locking portion 235. Therefore, it is possible to suppress the movement of the support column 23 away from the support column insertion portion 2513 and maintain the correct position between the support column 23 and the stand base 25.

[0018] [Internal structure of the stand] Figure 6 is a perspective cross-sectional view of stand 21 taken from the VI-VI section in Figure 2. Figure 7 is a cross-sectional view of stand 21 taken from the VII-VII section in Figure 2.

[0019] [Stand Base] A stand base 253 is fixed to the bottom surface of the stand cover 251. The stand base 253 is a component that constitutes the lower part of the stand base 25. The stand base 253 has a plate-like shape. The bottom surface of the stand base 253 is the installation surface for the stand 21 and the stand base 25, and it is preferable that it has a bottom area sufficient to prevent the display device 1 from easily tipping over. The stand base 253 has enough weight so that even when one end 237 is inserted into the support column insertion part 2513 and the other end of the support column 23 is connected to the display unit 11, the installation surface of the stand 21 does not float above the installation location. The stand base 253 can be formed from, for example, a resin material or a metal material, or a combination of different materials. The stand base 253 has an opening 2531. In a plan view, the opening 2531 and the support column insertion part 2513 overlap.

[0020] [Support post fixing member] The support column fixing member 255 is attached to the upper surface of the stand base 253 opposite to the bottom surface. The support column fixing member 255 is installed between the stand cover 251 and the stand base 253. As will be described in detail later, the support column fixing member 255 is a member for fixing the support column 23 to the stand base 25. The support column fixing member 255 can be made of, for example, a metal material. The support column fixing member 255 has a plate-like structure in part, and a contact portion 2551 which is a plate-like part having the upper surface of the plate-like structure. The contact portion 2551 is provided with a through hole 2553 for passing a screw 27, which will be described later.

[0021] In plan view, the stand base 25 consists of the column insertion portion 2513 of the stand cover 251, the contact portion 2551 of the column fixing member 255, and the opening 2531 of the stand base 253, all overlapping. That is, the upper surface of the contact portion 2551 becomes the bottom surface of the hole which is the column insertion portion 2513. The opening 2531 is an entry point for inserting the screw 27 through the through hole 2553 from the bottom side of the stand base 25.

[0022] [Stand structure] One end portion 237 is inserted into the support column insertion portion 2513 from the upper side of the stand base 25 through the insertion opening 2511. The insertion into the support column insertion portion 2513 is completed when the first lower end surface 2313, which is the lower end surface of the bottom portion 231 of the one end portion 237, comes into contact with the upper surface of the contact portion 2551. At this time, in a plan view, the screw hole 2311 and the through hole 2553 provided in the bottom portion 231 of the one end portion 237 overlap.

[0023] As described above, the cross-sectional shape of one end 237 and the shape of the insertion opening 2511 are approximately the same in plan view. Furthermore, in plan view, the cross-sectional shape of one end 237 and the cross-sectional shape surrounded by the inner wall 2517 that extends vertically inside the support column insertion part 2513 are approximately the same. The side surface of the support column 23 and the inner wall 2517 are adjacent to each other, facing each other and in surface contact. Therefore, the movement of one end 237 is restricted from the surroundings by the inner wall 2517, which suppresses the tilting of the support column 23 and makes it easy for the support column 23 to maintain a posture that extends perpendicularly to the upper surface of the stand base 25. In this embodiment, the inner wall 2517 is provided around the entire circumference inside the support column insertion part 2513 as an example, but it may be provided only partially.

[0024] [Different examples of interior walls] The first lower end surface 2313, which is the lower end surface of the bottom 231 of one end portion 237, is above the second lower end surface 25171, which is the lower end surface of the inner wall 2517. However, in order to maintain the vertical position of the support column 23, it is preferable that the first lower end surface 2313 and the second lower end surface 25171 be at the same height.

[0025] Figure 8 is a perspective cross-sectional view corresponding to Figure 6, relating to a modified example of Embodiment 1. In the structure shown in Figure 8, the first lower end surface 2313 and the second lower end surface 25171 are at the same height, and the inner wall 2517 makes surface contact with the entire side surface of one end 237, thereby more reliably maintaining the position in which the support column 23 extends perpendicularly to the upper surface of the stand base 25.

[0026] As shown in Figures 6 and 7, when the bottom portion 231 and the contact portion 2551 come into contact, the claw portion 2515 engages with the locking portion 235. The claw portion 2515 temporarily fastens the support column 23 to the stand base 25. At this time, the claw portion 2515 prevents the support column 23 from moving away from the support column insertion portion 2513, thereby maintaining the proper position of the support column 23 and the stand base 25. The claw portion 2515 can be formed from, for example, a resin material and may be integrated with the stand cover 251.

[0027] More specifically, in this embodiment, the claw portion 2515 has a projection 25153 that protrudes toward the area inside the support column insertion portion 2513 into which the support column 23 is inserted. The projection 25153 protrudes toward the side portion 233 of one end portion 237. In this embodiment, the projection 25153 protrudes into the locking portion 235, which is a hole opened in the side plate that is the side portion 233 of one end portion 237. That is, when one end portion 237 is inserted into the support column insertion portion 2513, the claw portion 2515 locks the locking portion 235 by the projection 25153 entering the hole that is the locking portion 235. At this time, the lower end surface of the projection 25153 is adjacent to the upper surface of the lower side of the hole in the locking portion 235. The lower end surface of the protruding portion 25153 contacts the upper surface of the lower edge of the hole which is the locking portion 235, thereby preventing the support column 23 from moving away from the stand base 25, and preventing the temporarily fixed support column 23 from falling out of the stand base 25.

[0028] As shown in Figure 6, it is preferable that the width of the protruding portion 25153 be approximately the same as the width of the locking portion 235 in the direction intersecting the direction in which the support column 23 is inserted, thereby maximizing the strength of the protruding portion.

[0029] The amount by which the protruding portion 25153 protrudes toward the support column 23 may gradually increase from the side into which the support column 23 is inserted toward the opposite side. As shown in Figure 7, in this embodiment, the protruding portion 25153 has a structure that slopes upward toward the opposite side from the side into which the support column 23 is inserted. The upward slope of the protruding portion 25153 prevents the lower end surface of the bottom portion 231 from catching on the protruding portion 25153 when the support column 23 is inserted into the support column insertion portion 2513, allowing the support column 23 to be inserted smoothly into the support column insertion portion 2513, and preventing damage to the claw portion 2515 and the protruding portion 25153.

[0030] As can be seen from Figures 5 and 7, a portion of the claw portion 2515 is plate-shaped and acts as an elastic leaf spring 25151. Specifically, the claw portion 2515 is provided in the portion of the inner wall 2517 that has been removed, specifically the portion facing the side portion 233 of one end 237. The structure is such that the leaf spring 25151 and the protruding portion 25153 are connected in that order from the insertion opening 2511 side downwards. In other words, along the insertion direction when the support column 23 is inserted, the claw portion 2515 has the leaf spring 25151 on the insertion opening 2511 side and the protruding portion 25153 on the contact portion 2551 side. This structure allows the claw portion 2515 to temporarily move the protruding portion 25153 out of the area through which the support column 23 passes, by bending the leaf spring 25151 outwards from the support column insertion portion 2513 during the insertion process from when the support column 23 is inserted into the support column insertion portion 2513 until the protruding portion 25153 enters the locking portion 235.

[0031] When the first lower end surface 2313 of the bottom portion 231 comes into contact with the upper surface of the contact portion 2551, the locked portion 235 is at the same height as the protruding portion 25153. Due to the elasticity of the leaf spring 25151, the protruding portion 25153 returns to the inside of the support column insertion portion 2513 and enters the locked portion 235. This prevents excessive load from being placed on the claw portion 2515 and the protruding portion 25153 when inserting the support column 23, thus preventing damage to the claw portion 2515 and the protruding portion 25153, and allowing the support column 23 to be smoothly inserted into the support column insertion portion 2513.

[0032] Furthermore, in this embodiment, since the cross-sectional shape of the support column 23 is channel-shaped, the inside of the support column 23 can be accessed from one open side of the support column 23. By pressing the protruding portion 25153 located inside the hole which is the locking portion 235 from the inside of the support column 23, the leaf spring 25151 can be bent outwards from the support column insertion portion 2513, thereby releasing the lock between the claw portion 2515 and the locking portion 235, and the support column 23 can be easily removed from the stand base 25. Therefore, for example, when the installation method of the display device 1 is changed to wall mounting, and the stand 21 is no longer needed, the stand 21 can be easily disassembled into its components and stored.

[0033] The screw 27 is inserted into the through hole 2553 from the opposite side of the stand base 25 from the side with the support column 23 and screwed into the screw hole 2311. In this embodiment, the screw 27 is inserted into the through hole 2553 from the bottom side of the stand base 253 through the opening 2531 and screwed into the screw hole 2311 of the bottom 231 of the support column 23. Therefore, the support column 23 and the support column fixing member 255 are fixed to each other by the screw 27 with the bottom 231 of the support column 23 in contact with the contact portion 2551. The support column 23 and the stand base 25 are permanently fixed by the screw 27, and the stand 21 is assembled. In this embodiment, each of the multiple screw holes 2311 and the multiple through holes 2553 is screwed into each of the multiple screws 27.

[0034] When installing the screw 27, once the support column 23 and the stand base 25 are temporarily fixed, as shown in Figure 3, the screw 27 must be inserted into the through hole 2553 with the bottom surface of the stand 21 facing upwards. In this state, gravity causes the support column 23 to move away from the stand base 25, but as mentioned above, in this embodiment, the claw portion 2515 and the locking portion 235 are locked together, preventing the support column 23 from moving away from the stand base 25, and preventing the temporarily fixed support column 23 from falling off the stand base 25. Therefore, the correct position of the support column 23 and the stand base 25 can be maintained, improving work efficiency. Furthermore, the correct position of each other can be maintained by the support column 23 and the stand base 25 alone, eliminating the need to prepare another jig to maintain the positional relationship of these components during work. Furthermore, when screwing in the screw 27, a force is applied to the screw hole 2311 of the bottom portion 231 in a direction that causes the support column 23 to move away from the stand base 25. However, even in this case, the locking of the claw portion 2515 and the locking portion 235 prevents the support column 23 from moving away from the stand base 25.

[0035] When the entire screw 27 is screwed into the screw hole 2311, it is located on the side of the support column fixing member 255 rather than the bottom surface of the stand base 253. Therefore, the screw head of the screw 27 does not protrude from the bottom surface of the stand base 25, and the bottom surface of the stand base 25, which is the installation surface, is used as a general plane, improving the ease of installation of the stand 21. Specifically, a through hole 2553 for the screw 27 to pass through is provided in the contact portion 2551, and the contact portion 2551 is a plate-like part having the upper surface of a platform-like structure, which is a part of the support column fixing member 255. With this structure, the entire screw 27 is located on the side of the stand cover 251 rather than the upper surface of the stand base 253, and the screw head of the screw 27 does not protrude from the bottom surface of the stand base 25.

[0036] The support column fixing member 255 may be omitted. In that case, for example, instead of providing an opening 2531 in the stand base 253, a contact portion and a through hole can be formed in the stand base 253 itself. If the screw 27 is a countersunk screw, even if a through hole is directly provided in the stand base 253, the screw head can be prevented from protruding from the bottom surface of the stand base 253, and the ease of installation of the stand 21 can be maintained.

[0037] [Embodiment 2] Figure 9 is a schematic diagram of the stand 31 according to Embodiment 2, viewed from above. The stand 31 according to Embodiment 2 differs from that of Embodiment 1 mainly in the structure of the support column 33 and the stand base 35. Hereafter, the same reference numerals are used for parts common to Embodiment 1, and the explanation will not be repeated.

[0038] [Support column of Embodiment 2] Figure 10 is a schematic diagram of the support column 33 according to Embodiment 2. In Embodiment 2, the support column 33 is a long, rod-shaped member, and its cross-sectional shape is channel-shaped. The support column 33 can be made of, for example, a resin material or a metal material. In this embodiment, the support column 33 is shown as a rod-shaped member with a channel-shaped cross-section, but it is sufficient that the side end surface 3331 of the side plate 333 is exposed, and for example, it may be a rod-shaped member with an L-shaped cross-section. A predetermined portion at one end of the support column 33 is defined as the end portion 337. As will be described in detail later, the end portion 337 is the portion that is inserted into the support column insertion portion 2513 of the stand cover 351. The other end of the support column 33, opposite to the end portion 337, is connected to the housing 13 of the display unit 11.

[0039] One end portion 337 includes a bottom portion 331, a side plate 333 having a side end surface 3331, and a locking portion 335 provided as a cutout portion of the side end surface 3331 of the side plate 333. In this embodiment, the bottom portion 331 is a plate-like portion and serves as a base plate. The lower surface of the bottom portion 331 is a surface having a normal parallel to the longitudinal direction of the support column 33. Screw holes 2311 are provided in the bottom portion 331. In this embodiment, multiple screw holes 2311 are provided, but any number of screw holes 2311 can be provided as long as there is one or more.

[0040] The main surface of the side plate 333 is a surface having a normal perpendicular to the longitudinal direction of the support column 33. A locking portion 335 is provided on the side end surface 3331 of the side plate 333. The locking portion 335 is the part that is locked by the claw portion 3515 of the stand cover 351, which will be described later. In this embodiment, the locking portion 335 is a part of the side end surface 3331 of the side plate 333 that has been cut out.

[0041] [Stand cover of Embodiment 2] Figure 11 is a perspective cross-sectional view of a stand cover 351 according to Embodiment 2, with a portion cut out. Specifically, the stand cover 351 in Figure 9 is partially cut along a direction intersecting the longitudinal direction. The stand cover 351 is a component that constitutes the upper part of the stand base 35. The stand cover 351 can be formed from, for example, a resin material. An insertion opening 2511, which is roughly rectangular in shape when viewed from above, is formed on the upper surface of the stand cover 351.

[0042] The stand cover 351 has a support column insertion section 2513, which is a hole with an insertion opening 2511 as an entrance and an inner wall 2517 as an inner side. The support column insertion section 2513 allows one end 337 to be inserted into the interior of the stand cover 351 through the insertion opening 2511 opened on the upper surface of the stand cover 351. In a plan view, the shape of the insertion opening 2511 matches the shape of the cross-section of the one end 337. In this embodiment, the shape of the insertion opening 2511 is roughly rectangular to match the support column 33 which has a channel-shaped cross-section. This makes it possible to suppress the wobbling of the support column 33 inserted into the support column insertion section 2513.

[0043] A claw portion 3515 is provided on the inside of the support column insertion portion 2513. The claw portion 3515 is provided on the inner circumferential surface of the support column insertion portion 2513, on the surface facing the side end surface 3331 of the side plate 333 when one end 337 is inserted into the support column insertion portion 2513. As will be described in detail later, when one end 337 is inserted into the support column insertion portion 2513 and the bottom portion 331 comes into contact with the contact portion 2551 of the support column fixing member 255, which will be described later, the claw portion 3515 locks the locking portion 335. Therefore, it is possible to suppress the movement of the support column 33 away from the support column insertion portion 2513 and maintain the correct position between the support column 33 and the stand base 35.

[0044] [Internal structure of the stand in embodiment 2] Figure 12 is a perspective cross-sectional view of stand 31 as seen from the XII-XII section in Figure 9. Figure 13 is a cross-sectional view of stand 31 as seen from the XIII-XIII section in Figure 9.

[0045] As shown in Figures 11 and 12, when the bottom portion 331 and the contact portion 2551 come into contact, the claw portion 3515 engages with the locking portion 335. The claw portion 3515 temporarily fastens the support column 33 to the stand base 35. At this time, the claw portion 3515 prevents the support column 33 from moving away from the support column insertion portion 2513, thereby maintaining the proper position of the support column 33 and the stand base 35. The claw portion 3515 can be formed from, for example, a resin material and may be integrated with the stand cover 351.

[0046] More specifically, in this embodiment, the claw portion 3515 has a projection 35153 that protrudes toward the area inside the support column insertion portion 2513 into which the support column 33 is inserted. The projection 35153 protrudes toward the side end face 3331 of one end portion 337. In this embodiment, the projection 35153 protrudes into the locking portion 335, which is a cut-out portion of the side end face 3331 of the side plate 333. That is, when one end portion 337 is inserted into the support column insertion portion 2513, the claw portion 3515 locks the locking portion 335 by the projection 35153 entering the cut-out portion which is the locking portion 335. At this time, the lower end face of the projection 35153 is adjacent to the upper surface of the lower side of the cut-out portion of the locking portion 335. The lower end surface of the protruding portion 35153 contacts the upper surface of the lower edge of the notched portion which is the locking portion 335, thereby preventing the support column 33 from moving away from the stand base 35 and preventing the temporarily fixed support column 33 from falling out of the stand base 35.

[0047] As shown in Figure 12, the width of the protrusion 35153 may be such that it can engage both of the locking portions 335 on the side end faces 3331 of the two side plates 333 in a direction intersecting the direction in which the support column 33 is inserted, or multiple protrusions 35153, each with a width that can engage one locking portion 335, may be arranged side by side in a direction intersecting the longitudinal direction of the support column 33. Note that the locking portion 335 only needs to be provided on the side end face 3331 of at least one of the side plates 333, and the claw portion 3515 only needs to be able to engage with at least one of the locking portions 335.

[0048] The amount by which the protruding portion 35153 protrudes toward the support column 33 may gradually increase from the side into which the support column 33 is inserted toward the opposite side. As shown in Figure 13, in this embodiment, the protruding portion 35153 has an upward sloping structure from the side into which the support column 33 is inserted toward the opposite side. The upward sloping of the protruding portion 35153 prevents the lower end surface of the bottom portion 331 from catching on the protruding portion 35153 when the support column 33 is inserted into the support column insertion portion 2513, allowing the support column 33 to be inserted smoothly into the support column insertion portion 2513, and preventing damage to the claw portion 3515 and the protruding portion 35153.

[0049] As can be seen from Figures 11 and 13, a portion of the claw portion 3515 is plate-shaped and acts as an elastic leaf spring 35151. Specifically, the claw portion 3515 replaces the inner wall 2517 that faces the side end face 3331 of one end 337, and has a structure in which the leaf spring 35151 and the protruding portion 35153 are connected in that order from the insertion opening 2511 side downwards. In other words, along the insertion direction when the support column 33 is inserted, the claw portion 3515 has the leaf spring 35151 on the insertion opening 2511 side and the protruding portion 35153 on the contact portion 2551 side. This structure allows the claw portion 3515 to temporarily move the protruding portion 35153 out of the area through which the support column 33 passes, by bending the leaf spring 35151 outwards from the support column insertion portion 2513 during the insertion process from when the support column 33 is inserted into the support column insertion portion 2513 until the protruding portion 35153 enters the locking portion 335.

[0050] When the first lower end surface 3313 of the bottom portion 331 comes into contact with the upper surface of the contact portion 2551, the locked portion 335 comes to the same height as the protruding portion 35153. Due to the elasticity of the leaf spring 35151, the protruding portion 35153 returns to the inside of the support column insertion portion 2513 and enters the locked portion 335. This prevents excessive load from being placed on the claw portion 3515 and the protruding portion 35153 when inserting the support column 33, thus preventing damage to the claw portion 3515 and the protruding portion 35153, and allowing the support column 33 to be smoothly inserted into the support column insertion portion 2513.

[0051] Furthermore, in this embodiment, since the cross-sectional shape of the support column 33 is channel-shaped, the inside of the support column 33 can be accessed from one open side. By pressing the claw portion 3515 and the protruding portion 25153 from the inside of the support column 33 and bending the leaf spring 35151 outward from the support column insertion portion 2513, the locking between the claw portion 3515 and the locking portion 335 can be released, and the support column 33 can be easily removed from the stand base 35. Therefore, for example, when the installation method of the display device 1 is changed to wall mounting, and the stand 31 is no longer needed, the stand 31 can be easily disassembled into its components and stored.

[0052] [Modified version of Embodiment 2] Figure 14 is a cross-sectional view of a modified stand according to Embodiment 2. In this modified example, one end portion 337 includes a bottom portion 331 and a side plate 333, with the bottom portion 331 serving as the locking portion. Therefore, it is not necessary to provide a locking portion on the side plate 333.

[0053] More specifically, the claw portion 3515 has a projection 35153 that protrudes towards the area inside the support column insertion portion 2513 into which the support column 33 is inserted. In this modified example, the projection 35153 protrudes above the upper surface of the bottom portion 331. That is, when one end portion 337 is inserted into the support column insertion portion 2513, the claw portion 3515 locks the bottom portion 331 as the locking portion. At this time, the lower end surface of the projection 35153 is adjacent to the upper surface of the bottom portion 331. The lower end surface of the projection 35153 contacts the upper surface of the bottom portion 331, which prevents the support column 33 from moving away from the stand base 35, and prevents the temporarily fixed support column 33 from falling out of the stand base 35. Furthermore, in this modified example, since the bottom portion 331 becomes the locking portion, there is no need to process a hole or notch in the end portion 337 of the support column 33 to serve as the locking portion. In this modified example, it is sufficient that there is space at the end portion 337 for the claw portion 3515 to protrude above the bottom portion 331, and for example, the cross-sectional shape of the support column 33 may be L-shaped.

[0054] Furthermore, this disclosure is not limited to the embodiments and modified configurations described above, and may be replaced with configurations that are substantially the same as those shown in the embodiments and modified configurations described above, configurations that produce the same effects, or configurations that can achieve the same purpose.
