Mode for Carrying Out the Invention

[0008] Hereinafter, the display device according to the embodiment of the present disclosure will be described with reference to the drawings. In the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant descriptions will not be repeated.

[0009] (Embodiment 1) The display device 1000 according to Embodiment 1 will be described with reference to FIGS. 1 to 7.

[0010] FIGS. 1 and 2 are front views of the display device 1000 according to the present embodiment. FIG. 2 is a right side view of the display device 1000 according to the present embodiment.

[0011] As shown in FIGS. 1 and 2, the display device 1000 includes a stand 100 and a display panel 200.

[0012] The stand 100 is placed, for example, on a desk or the floor. The stand 100 includes a stand body 10, a swivel 20 rotatably attached to the stand body 10, and a mounting portion 30 fixed to the swivel 20. The stand body 10 has a base plate 10A and a neck portion 10B. The base plate 10A is installed so as to extend along the surface of a desk or the floor or the like. The neck portion 10B extends upward from the base plate 10A. The base plate 10A and the neck portion 10B are integrally formed, but may be formed by joining two separate parts.

[0013] The swivel 20 is attached to the upper end of the neck portion 10B of the stand body 10. The attachment portion 30 is fixed to the upper end of the swivel 20. The attachment portion 30 is fixed to the rear surface of the display panel 200. In the present disclosure, the swivel refers to, for example, in a display device composed of a display panel and a stand to which the display panel is attached, a structure that enables the display panel to rotate with respect to the stand while maintaining the state in which the display panel is attached to the stand. This structure is not limited to the structure of a display device, but can be the structure of any device as long as it is a structure that enables the supported body to rotate while maintaining the state in which the supported body is attached to the support body in a device composed of a supported body to be supported and a support body to which the supported body is attached.

[0014] The display panel 200 has a screen 200A for displaying an image. The surface on which the screen 200A of the display panel 200 is provided is the front surface of the display device 1000. The display panel 200 has a horizontally long rectangular plate shape. The neck portion 10B of the stand 100 is attached to the back surface of the display panel 200. The display panel 200 is attached to the stand 100 by the swivel 20 so as to be rotatable. That is, the display panel 200 can perform a so-called nodding operation with respect to the stand 100. The nodding operation is, for example, an operation of rotating in the horizontal direction with respect to a rotation axis extending in the vertical direction (vertically).

[0015] The swivel 20 includes a fixed portion 1, a rotating portion 2, a locking portion 3, and an operating portion 4. The fixed portion 1 is attached to the upper end of the neck portion 10B of the stand body 10. The rotating portion 2 is provided at the upper end of the fixed portion 1. The rotating portion 2 is fixed to the lower end of the attachment portion 30. The locking portion 3 and the operating portion 4 are provided across both the fixed portion 1 and the rotating portion 2 at the front portion of the swivel 20.

[0016] FIG. 3 is a perspective view of the locking state of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 4 is a partial side view of the locking state of the locking portion 3 and the operation portion 4 of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 5 is a perspective view of the unlocking state of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 6 is a partial side view of the unlocking state of the locking portion 3 and the operation portion 4 of the swivel 20 of the display device 1000 according to the present embodiment.

[0017] In the present embodiment, the fixing portion 1 is fixed to the stand main body 10. However, the fixing portion 1 and the stand main body 10 may be integrally formed. That is, the fixing portion 1 may be a part of the stand main body 10.

[0018] The rotating portion 2 has a through hole 2A and is annular. A rotating shaft 12, which is a part of the fixing portion 1, is inserted into the through hole 2A. The rotating portion 2 is rotatably attached around the rotating shaft 12 of the fixing portion 1. That is, the rotating portion 2 is hinge-jointed to the fixing portion 1. The rotating portion 2 is fixed to the display panel 200 via the attachment portion 30.

[0019] The locking portion 3 includes a locked portion E2 rotatably provided on the fixing portion 1 and two locking portions E1 integrated with the rotating portion 2. Each of the locked portion E1 of the locking portion 3 and the operation portion 4 is a rod-shaped member. The locking portion E1 of the locking portion 3 and the operation portion 4 are integrated and form an equilateral mountain shape. The locking portion E1 of the locking portion 3 and the operation portion 4 are rotatably attached to both inner side surfaces of the vertical groove 1A of the fixing portion 1 around the rotary hinge 34. The locking portion E1 of the locking portion 3 is provided so as to extend from the upper portion of the fixing portion 1 to the rotating portion 2. The operation portion 4 is provided at the upper portion of the fixing portion 1.

[0020] The locking portion 3 is composed of one locked portion E2 of the fixing portion 1 and two locking portions E1 of the rotating portion 2. The locked portion E1 is integrated with the operation portion 4 and is rotatably attached to both inner side surfaces of the vertical groove 1A of the fixing portion 1 around the rotary hinge 34.

[0021] In the present embodiment, the locked portion E2 is inserted between the two locking portions E1 by rotating toward the rotating portion 2 around the rotary hinge 34. Thereby, the locked portion E2 is locked to the two locking portions E1. As a result, in the locked state, the rotating portion 2 cannot rotate around the rotation axis 12. On the other hand, the locked portion E2 is withdrawn from between the two locking portions E1 by rotating away from the rotating portion 2 around the rotary hinge 34. Thereby, the locking by the two locking portions E1 is released. As a result, in the unlocked state, the rotating portion 2 can rotate around the rotation axis 12.

[0022] As can be seen from FIGS. 3 to 6, the locked state of the locked portion E2 by the locking portion E1 is maintained by the fitting of the convex portion PR protruding from the locked portion E2 (both outer side surfaces of the rod-shaped member) and the concave portion DE provided on the locking portion E1 (both inner side surfaces of the groove) for receiving the convex portion PR. However, the locked state of the locked portion E2 by the locking portion E1 may be maintained only by the frictional force generated between the locked portion E2 and each of the two locking portions E1.

[0023] The lock portion 3 is switched to either the locked state shown in FIGS. 3 and 4 or the unlocked state shown in FIGS. 5 and 6 by the operation of the operation portion 4 by the user. Hereinafter, the swivel 20 in the locked state and the unlocked state will be specifically described.

[0024] When the user wants to set the swivel 20 to the locked state (locked state), the user operates the operation portion 4 with a hand inserted between the lower end of the display panel 200 and the upper end of the base plate 10A. Thereby, as shown in FIGS. 3 and 4, the lock portion 3 is switched to the locked state (locked state) that inhibits the rotation of the rotating portion 2 with respect to the fixed portion 1 by the operation of the operation portion 4 by the user. At this time, the locked portion E2 is locked to the locking portion E1. Therefore, in the locked state, the rotating portion 2 is fixed to the fixed portion 1. Thereby, the display panel 200 is fixed to the stand 100. As a result, the orientation of the screen 200A of the display panel 200 with respect to the stand 100 is fixed.

[0025] Similarly, when the user wants to unlock the swivel 20 (unlock state), the user operates the operation unit 4 with a hand inserted between the lower end of the display panel 200 and the upper end of the base plate 10A. As a result, as shown in FIGS. 5 and 6, the locking unit 3 is switched to an unlocked state (unlocked state) that allows the rotating unit 2 to rotate with respect to the fixing unit 1 by the operation of the operation unit 4 by the user. At this time, the locking of the locked portion E2 by the locking portion E1 is released. Therefore, in the unlocked state, the rotating unit 2 can rotate with respect to the fixing unit 1. Thereby, the orientation of the screen 200A of the display panel 200 with respect to the stand 100 can be changed.

[0026] In addition, when there is no space or the space is narrow between the lower end of the display panel 200 and the upper end of the base plate 10A, for example, the neck portion 10B of the stand 100 may be provided so as to extend to the vicinity of the uppermost portion of the display panel 200. In this case, the user can extend a hand from the upper side of the display panel 200 to the back side of the display panel 200 to lock or unlock the swivel 20 (locked state or unlocked state).

[0027] The operation unit 4 is integrated with the locked portion E2 of the locking unit 3. Therefore, when the operation unit 4 is rotated, the locked portion E2 of the locking unit 3 rotates around the rotary hinge 34. Therefore, the user can switch the locking unit 3 (locked portion E2) to either the locked state or the unlocked state by operating the operation unit 4.

[0028] Note that the operation unit 4 can be pulled out from the vertical groove 1A on the circumferential surface of the fixing unit 1 to lock the locked portion E1, but the locked portion E2 can also be pushed into the vertical groove 1A between the two locking portions E1 to lock the locked portion E2. Further, the locked portion E2 can be pulled out from between the two locking portions E1 to unlock the locked portion E2, but the operation unit 4 can also be pushed into the vertical groove 1A of the fixing unit 1 to unlock the locked portion E2. In these cases, it can be said that the locked portion E2 of the locking unit 3 and the operation unit 4 are constituted by an integrally inseparable same part.

[0029] The operation unit 4 of the present embodiment is provided at any position on the front semi - circle around the rotation axis 12 of the swivel 20. That is, the operation unit 4 is provided at a position where it can be operated from the front side of the display device 1000. Therefore, the user can perform an operation on the operation unit 4 to switch the state of the locking unit 3 between the locked state and the unlocked state while staying in front of the display panel 200 without moving to the rear side of the display panel 200. Thus, the user can easily switch the locking unit 3 between the locked state and the unlocked state.

[0030] More specifically, the operation unit 4 of the present embodiment is provided so as to face the front side of the display device 1000. Therefore, the user can operate the operation unit 4 while looking at the position of the operation unit 4 at a position in front of the display device 1000. As a result, the operation of the operation unit 4 for switching the locking unit 3 can be performed extremely easily.

[0031] In the present embodiment, two locking portions E1 function as a mark portion indicating a position for locking the fixed portion 1 and the rotating portion 2 when the display device 1000 is viewed from the front side. Since there are two locking portions E1 as the mark portion, the user can easily insert the locked portion E2 between the two locking portions E1.

[0032] FIG. 7 is a plan view of a modified example of the rotating portion 2 of the swivel 20 of the display device 1000 of the present embodiment.

[0033] As shown in FIG. 7, a plurality of locking portions E1 may be provided on the rotating portion 2. According to this, the locked portion E2 is locked at a position between any two of the plurality of locking portions E1. Therefore, according to the number of positions between any two of the plurality of locking portions E1, the rotation angle of the rotating portion 2 with respect to the fixed portion 1 can be selected. That is, if a plurality of locking portions E1 are provided on the rotating portion 2, the orientation of the screen of the display panel 200 with respect to the stand 100 can be selected by selecting a position between any two of the plurality of locking portions E1.

[0034] (Embodiment 2) The display device 1000 according to Embodiment 2 will be described with reference to FIGS. 8 and 9. Note that descriptions of points that are the same as those of the display device 1000 according to Embodiment 1 will not be repeated below. The display device 1000 according to the present embodiment is different from the display device 1000 according to Embodiment 1 in the following points.

[0035] FIG. 8 is a perspective view of the lock state of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 9 is a perspective view of the unlock state of the swivel 20 of the display device 1000 according to the present embodiment.

[0036] As shown in FIGS. 8 and 9, the display device 1000 according to the present embodiment is different from the display device 1000 according to Embodiment 1 in that a recess 11 is provided at the upper end portion of the fixed portion 1. In the present embodiment, the lock portion 3 and the operation portion 4 are provided so as to straddle the lower end surface of the recess 11 in the vertical direction.

[0037] Both the left and right end surfaces of the recess 11 of the swivel 20 serve as a limiting portion R that limits the rotation range of the rotating portion 2 with respect to the fixed portion 1. The limiting portion R limits the rotational movement range of the locking portion E1. Thereby, the upper limit value and the lower limit value of the rotation angle of the rotating portion 2 with respect to the fixed portion 1 are determined. As a result, according to the display device 1000 of the present embodiment, the rotation range of the display panel 200 with respect to the stand 100 can be limited. Therefore, it is possible to suppress the rotation of the display panel 200 with respect to the stand 100 from becoming excessively large.

[0038] Also in this embodiment, the operation unit 4 is provided at a position where it can be operated from the front side of the display device 1000. More specifically, the operation unit 4 of this embodiment is provided so as to face the front side of the display device 1000. Therefore, the user can operate the operation unit 4 to switch the state of the locking unit 3 to either the locked state or the unlocked state while staying at a position in front of the display panel 200 without moving to the rear side of the display panel 200.

[0039] Also in this embodiment, as shown in FIG. 7 of Embodiment 1, a plurality of locking portions E1 may be provided on the rotating portion 2 at intervals along the rotation direction of the rotating portion 2. Also by this, similar to Embodiment 1, by selecting a position between any two of the plurality of locking portions E1, the screen orientation of the display panel 200 with respect to the stand 100 can be selected. Also in this case, similar to Embodiment 1, any two of the plurality of locking portions E1 function as a plurality of marking portions indicating positions for locking the fixed portion 1 and the rotating portion 2.

[0040] (Embodiment 3) The display device 1000 of Embodiment 3 will be described with reference to FIGS. 10 to 15. Note that the description of the points that are the same as those of the display device 1000 of Embodiment 1 or 2 will not be repeated below. The display device 1000 of this embodiment is different from the display device 1000 of Embodiment 1 or 2 in the following points.

[0041] FIG. 10 is a perspective view of the lock state of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 11 is a partial side view of the lock state of the lock portion 3 and the operation portion 4 of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 12 is a perspective view of the unlock state of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 13 is a partial side view of the unlock state of the lock portion 3 and the operation portion 4 of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 14 is a cross-sectional view of the unlock state of the swivel 20 of the display device 1000 according to the present embodiment, which is a cross-sectional view taken along line XIV-XIV of FIG. 13.

[0042] Unlike in the first and second embodiments, the lock portion 3 of the present embodiment has a locked portion E1 rotatably attached around the rotation hinge 24 of the rotating portion 2, and the locking portion E1 is provided on the fixed portion 1.

[0043] As shown in FIGS. 10 and 11, in the locked state, the operation portion 4 is configured to be able to move the locked portion E1 so that the locked portion E1 is locked by the two locking portions E1. Also, as shown in FIGS. 12 and 13, in the unlocked state, the operation portion 4 is configured to be able to move the locked portion E1 so that the locking of the locked portion E1 by the two locking portions E1 is released.

[0044] In the present embodiment, the lock portion 3 and the operation portion 4 are provided on the right side surface of the stand 100 so as to face the right side of the display device 1000. However, the operation portion 4 may be provided on the left side surface of the stand 100 so as to face the left side of the display device 1000. According to this, compared with the case where the operation portion 4 is provided on the front side surface of the stand 100 so as to face the front side of the display device 1000, it is possible to suppress the impairment of the aesthetics of the front portion of the display device 1000.

[0045] It can be said that the operation unit 4 of this embodiment is also provided at a position where it can be operated from the front side of the display device 1000. In other words, it can be said that the operation unit 4 of this embodiment is provided at any position on the front semi - circle around the rotation axis of the swivel 20. Therefore, also by the lock unit 3 of this embodiment, the user can very easily perform the operation of the operation unit 4 for switching the lock unit 3 between the locked state and the unlocked state while being in front of the display device 1000.

[0046] As shown in FIG. 11, the swivel 20 includes a maintaining unit M that maintains the unlocked state of the lock unit 3. The maintaining unit M maintains the locked state of the lock unit 3 by the fitting (press - fitting) of the convex portions M1 provided on both inner side surfaces of the protruding portion 22 of the rotating portion 2 with the concave portions M2 provided on both outer side surfaces of the locked portion E2. Therefore, it is possible to prevent the lock unit 3 from changing from the unlocked state to the locked state when the user does not intend it.

[0047] As shown in FIGS. 12 to 14, in the maintaining unit M, the concave portions M2 provided on both outer side surfaces of the locked portion E2 are placed on the convex portions M1 provided on both inner side surfaces of the protruding portion 22 of the rotating portion 2. Thereby, the maintaining unit M can maintain the unlocked state of the lock unit 3.

[0048] FIG. 15 is a plan view of a modification of the fixing portion 1 of the swivel 20 of the display device 1000 of this embodiment.

[0049] As shown in FIG. 15, in the modification of this embodiment, a plurality of locking portions E1 are provided on the rotating portion 2 at intervals along the rotation direction of the rotating portion 2. According to this, by selecting a position between any two of the plurality of locking portions E1, the orientation of the screen 200A of the display panel 200 with respect to the stand 100 can be selected. Also in this embodiment, similar to Embodiment 1, any two of the plurality of locking portions E1 function as a plurality of marking portions indicating positions for locking the fixing portion 1 and the rotating portion 2.

[0050] (Embodiment 4) The display device 1000 according to Embodiment 4 will be described with reference to FIGS. 16 and 17. Note that descriptions of the same points as the display device 1000 according to Embodiments 1 to 3 will not be repeated below. The display device 1000 according to the present embodiment is different from the display devices 1000 according to Embodiments 1 to 3 in the following points.

[0051] FIG. 16 is a perspective view of the lock state of the swivel 20 of the display device 1000 according to the present embodiment. FIG. 17 is a perspective view of the unlock state of the swivel 20 of the display device 1000 according to the present embodiment.

[0052] As shown in FIGS. 16 and 17, the locked portion E1 and the locking portion E1 according to the present embodiment have a shape in which the side surfaces of the ends of two rod-shaped members are connected to each other. In the present embodiment, the locked portion E1 and the operation portion 4 of the lock portion 3 are switched between a locked state and an unlocked state by rotating around the rotation hinge 14. Also in the present embodiment, the lock portion 3 and the operation portion 4 are provided on the right side surface of the stand 100 so as to face the right side of the display device 1000. However, the operation portion 4 may be provided on the left side surface of the stand 100 so as to face the left side of the display device 1000.

[0053] Similar to the operation portion 4 according to the foregoing embodiment, the operation portion 4 according to the present embodiment is also provided at a position where it can be operated from the front side of the display device 1000. In other words, the operation portion 4 according to the present embodiment is provided at any position on the front half circle around the rotation axis 12 of the swivel 20. Therefore, the user can operate the operation portion 4 for switching the lock portion 3 to either the locked state or the unlocked state while staying at the position on the front side of the display panel 200 without moving to the rear side of the display panel 200.

[0054] Also, in this embodiment as well, similar to Embodiment 3, the operation unit 4 is provided so as to face the right side or the left side of the display device 1000. Therefore, while suppressing the impairment of the aesthetics of the front portion of the display device 1000, the operation of the operation unit 4 for switching the lock unit 3 to either the locked state or the unlocked state can be easily performed.

[0055] Also in this embodiment, as shown in FIG. 7 of Embodiment 1, a plurality of locking portions E1 may be provided on the rotating portion 2 at intervals along the rotating direction of the rotating portion 2. Also in this embodiment, similar to Embodiment 1, any two of the plurality of locking portions E1 function as a plurality of marking portions indicating positions for locking the fixed portion 1 and the rotating portion 2.

[0056] (Embodiment 5) The display device 1000 of Embodiment 5 will be described with reference to FIGS. 18 to 20. Note that the description of the points that are the same as those of the display device 1000 of Embodiments 1 to 4 will not be repeated below. The display device 1000 of this embodiment is different from the display devices 1000 of Embodiments 1 to 4 in the following points.

[0057] FIG. 18 is an exploded perspective view of the swivel 20 of the display device 1000 of this embodiment. FIG. 19 is a partial side view of the swivel 20 of the display device 1000 of this embodiment in the locked state. FIG. 20 is a partial side view of the swivel 20 of the display device 1000 of this embodiment in the unlocked state.

[0058] As shown in FIGS. 18 to 20, also in this embodiment, the lock portion 3 includes a locked portion E2 and a locking portion E1 to which the locked portion E2 is locked. The locked portion E2 is fixed to the operation portion 4 and is movably attached to the rotation portion 2 together with the operation portion 4. The locked portion E2 is constituted by an insertion portion P attached to the rotation portion 2. The insertion portion P is inserted into the second through hole T2 after being inserted into the first through hole TH1. The locking portion E1 is constituted by a second through hole TH2 provided in the fixed portion 1 so as to be able to lock the locked portion E2. When the locked portion E2 (insertion portion P) moves downward by the operation of the operation portion 4, it is locked (inserted) to the locking portion E1 (second through hole TH2) in the locked state. On the other hand, in the unlocked state, when the locked portion E2 (insertion portion P) moves upward by the operation of the operation portion 4, it is released from the locking (insertion) by the locking portion E1 (second through hole TH2).

[0059] That is, in the display device 1000 of this embodiment, the lock portion 3 includes a second through hole TH2 provided in the fixed portion 1 as the locking portion E1 and an insertion portion P provided in the rotation portion 2 as the locked portion E1. When the insertion portion P as the locked portion E1 rotates downward around the rotation hinge 24 by the operation of the operation portion 4, it is inserted into both the first through hole TH1 and the second through hole TH2. Thereby, the lock portion 3 is in the locked state. On the other hand, when the insertion portion P as the locked portion E1 rotates upward around the rotation hinge 24 by the operation of the operation portion 4, it comes out of the first through hole TH1 and the second through hole TH2. Thereby, the lock portion 3 is in the unlocked state. When the lock portion 3 is in the unlocked state, as shown in FIG. 20, even if the user releases their hand from the operation portion 4, friction is generated between the inner peripheral surface of the hole into which the rotation hinge 24 is inserted and the outer peripheral surface of the rotation hinge 24 so that the operation portion 4 is held in that position. The inner peripheral surface of the hole into which the rotation hinge 24 is inserted and the outer peripheral surface of the rotation hinge 24 are formed so that this frictional force increases as the operation portion 4 moves upward. Thereby, the operation portion 4 stops at a certain height and does not fall due to gravity from that position.

[0060] Also in this embodiment, the operation unit 4 is provided on the right side surface of the stand 100 so as to face the right side of the display device 1000. However, the operation unit 4 may be provided on the left side surface of the stand 100 so as to face the left side of the display device 1000.

[0061] Such an operation unit 4 of this embodiment is also provided at a position where it can be operated from the front side of the display device 1000, similar to the operation unit 4 of the foregoing embodiment.
