  The installation rail 13 serves as an installation rail for the display device 1 when the display device 1 is separated from the stand column 30, and is provided on the lower surface of the display device 1 (side closer to the stand base 29). As the material, a material having an anti-slip effect, such as rubber or silicon, can be used, and the shape is curved with a length that can be installed following the elevation angle of the display device 1 (approximately) The rail shape (convex shape) has an arc shape (including an arc shape having a center on the display device 1 side). The installation rails 13 can be provided at one or more places over a predetermined length under the display device 1 so as to exert the above-described effects, but by reducing the width and providing a plurality of them in parallel, The above effects can be realized with a small amount of material.

[Connector 15]
Next, the connecting body 15 will be described with reference to FIGS.
The connecting body 15 is formed in an annular shape, and includes a gripping portion 17, a fixing portion 19 that is fixed to the back side cover 7 of the display device 1, a substantially rod-shaped stand and connecting portion 23, and the stand and connecting portion 23. The first rotation shaft portion 21 is connected to the display device 1 so as to be rotatable.

  The stand and connecting portion 23 functions as a connecting portion that is inserted into the insertion hole 27 of the stand column 30 and connects the display device 1 and the stand column 30 in the first usage pattern. Further, in the second usage pattern, the stand and connecting portion 23 functions as a stand portion that supports the display device 1. Moreover, the stand and connecting portion 23 also functions as an insertion / removal unit that shifts the first usage pattern and the second usage pattern by inserting / removing the first usage pattern from the stand column 30.

  The gripping part 17 has an arc shape (ring), and an antiskid member 17a made of anti-slip rubber, silicon or the like when gripped is formed in an arc shape inside the arc shape ( FIG. 1).

  Further, as shown in FIG. 6, the grip portion 17 is also a portion that can be engaged with a protrusion provided on the wall 31 or the like, for example, a hook 33. Therefore, since the thickness of the first rotating portion 21 or the stand / connecting portion 23 (front side frame 1a-back side cover 7 direction D) is larger than the thickness of the fixed portion 19, the gripping portion 17 as shown in FIG. Is formed obliquely with respect to the fixed portion 19 in the direction away from the fixed portion 19 in the thickness direction D of the display device 1, that is, in the depth direction D 1 of the display device 1. More specifically, the position in the thickness direction D, that is, the dimension in the depth direction D1 of the display device 1, of the engaging portion (the arc tip portion) of the grip portion 17 with the hook 33 is the first rotation shaft portion 21. Alternatively, the grip portion 17 can be brought closer to the wall 31 by forming the stand / connecting portion 23 substantially the same as the dimension in the depth direction D1 of the display device 1, and the hook 33 having a short protruding length from the wall 31 can also be used. In addition to being attachable, the display surface of the liquid crystal display 3 can be substantially parallel to the surface of the wall 31 in a wall-mounted state.

  The fixing unit 19 is fixed to the internal chassis by screws with the back side cover 7 of the display device 1 interposed therebetween.

  The first rotation shaft portion 21 is positioned below the center position with respect to the length in the insertion / removal direction H with respect to the stand column 30 of the display device 1, so that the angle adjustment range in the upward direction is adjusted according to the usability. The stand-and-connecting portion 23 is clamped with such a strength that the display device 1 maintains the posture after the rotation in the elevation angle direction X. Further, the rotation axis is parallel to the width direction of the display device 1.

  The stand and connecting portion 23 includes a rotating portion 23a that is rotatably held by the first rotating shaft portion 21 at the base end portion, and rubber and silicon at the distal end side that is the other end side of the rotating portion 23a. It is formed in a circular cross section (regardless of a cylinder or a cylinder) having a slip stopper and a slip stopper / buffer member 23b functioning as a shock absorber.

  As shown in FIG. 2, the length of the stand and connecting portion 23 in the longitudinal direction (the direction from the base end portion to the distal end side) is set so that the length of the stand and connecting portion 23 is parallel to the liquid crystal display 3. In this state, the display device 1 is formed to have a length (including the same length) that is equal to or longer than the bottom 1b of the front frame 1a. In this embodiment, the length from the bottom side 1b of the front side frame 1a of the display device 1 is 113 mm, and the protruding amount is about 19 mm from the bottom side 1b. Therefore, the state of FIG. As shown in FIG. 1, the stand and connecting portion 23 has a length that extends below the bottom side 1 b of the front frame 1 a.

The reason for this configuration is as follows.
(1) For example, in the case of a liquid crystal display, which is a typical example of a thin display device, from the viewpoint of the tilt angle, the liquid crystal display has a problem of viewing angle, and can be used in various usage scenes such as watching the liquid crystal display lying down. The required tilt angle is necessary. In order to cope with this, when the stand and connecting portion 23 is used as a support stand for supporting the display device 1 as the second usage pattern, the length of the support stand is set so that the support stand is substantially parallel. The major point is that the length protrudes from the lower end side of the display unit. This protruding length provides a large degree of freedom in the variable angle.

  Further, in view of the relationship with the installation space, it is necessary to ensure a large inclination angle even in a narrow space. For this purpose, it is desirable that the position of the connecting portion of the stand and connecting portion 23 with the display device 1 is attached as low as possible. The distance between the grounding portion (lower side) of the display device 1 and the grounding portion (tip) of the stand / connection portion 23 can be reduced, and the stand / connection portion 23 can be used in a space-saving manner when the display device 1 is supported alone as a stand. Because.

  If the position of the first rotation shaft portion 21 is below the display device and the support stand is substantially parallel, the space slightly protrudes from the lower end side of the display portion. A large tilt angle can be obtained.

(2) In the case of a thin display device, it is one of the features that it is wall-mounted, but there is an advantage that the longer the support stand is, the more stable it can be attached.

  In addition, although the above-mentioned holding | grip part 17, the stand and connection part 23, and the 1st rotation part 21 are integrally formed as the connection body 15, and are attached to the display apparatus 1, they may be attached separately. Of course. However, the one-piece formation has the advantage that the assembly is easy and the manufacturing cost can be reduced.

[Stand post 30]
Next, the stand support | pillar part 30 is comprised from the support | pillar 25 and the stand base 29, and these are demonstrated referring FIGS. 1-5.
The support column 25 is a columnar member having a length capable of forming an insertion hole 27 that allows a rod-shaped portion having a circular cross section excluding the rotating portion 23 a of the stand-and-connecting portion 23 to be freely inserted and removed, and stands on the stand base 29. It is fixed and formed.

  The insertion hole 27 is a hole having a circular cross section, and in a state where the stand / connection portion 23 is inserted, the anti-slip / buffer material 23b of the stand / connection portion 23 abuts against the bottom of the insertion hole 27 and the stand / connection portion 23 is inserted. Support. Also, the diameter of the insertion hole 27 is such that the stand / connector 23 can be inserted / removed, and the stand / connector 23 has a gap that allows the stand / connector 23 to rotate about the longitudinal axis of the stand / connector 23. Is formed.

  The stand base 29 has a size capable of supporting the display device 1 at a predetermined height via the support column 25 and the connecting body 15.

Next, functions and effects of the above-described stand type thin television will be described.
First, in a first usage pattern in which the stand column 30 is used, as shown in FIGS. 2A to 2B, the stand and connecting portion 23 of the connecting body 15 fixed to the back side of the display device 1 is used as the column 25. The display device 1 is supported by being inserted into the insertion hole 27. The adjustment of the elevation angle direction X of the display device 1 in the first usage pattern is performed by rotating the first rotation shaft portion 21 with respect to the rotation portion 23a of the stand and connecting portion 23 as shown in FIG. It is done by doing. Further, the adjustment of the orientation in the horizontal direction Y of the display device 1 in the first usage pattern is performed in such a manner that the display device 1 is horizontally oriented with respect to the support column 25 with the stand and connecting portion 23 as the central axis as shown in FIG. Rotating to Y, that is, rotating the stand and connecting portion 23 around the longitudinal direction in the insertion hole 27 is performed. When the stand and connecting portion 23 is used by inserting it into the stand column 30 into the insertion hole 27, the longer the length of the stand and connecting portion 23, the more stably the display device 1 is supported. It is sufficient that the length of the display device 1 is such that the display device 1 can be supported by the stand support column 30 by inserting it into the insertion hole 27 of the stand support column 30. On the other hand, the length of the stand / connecting portion 23 inserted into the insertion hole 27 of the stand column 30 so that the display device 1 cannot be supported and falls without a screw or the like as in the conventional example (FIG. 26). Don't be. The specific length is designed according to the size / weight of the display device 1, the size of the stand base 29, the height of the stand column 30, and the like.

  Next, as shown in FIGS. 2 (b) to 2 (a), the second usage pattern in which the stand / connecting portion 23 is used as a stand for supporting the display device 1 without using the stand column 30 is, for example, gripping The stand and connecting portion 23 is pulled out from the insertion hole 27 of the column 25 with the portion 17, and the installation rail 13 provided on the lower surface of the display device 1 and the slide provided at the tip of the stand and connecting portion 23 as shown in FIG. It is formed by supporting the display device 1 with a stop / buffer material 23b.

  Since the length of the stand and connecting portion 23 is longer than the bottom side 1b of the display device 1, the angle of the stand and connecting portion 23 with respect to the liquid crystal display 3 is adjusted, so that the installation rail 13 and the non-slip The elevation angle X of the liquid crystal display 3 (the vertical direction of the liquid crystal display 3) can be adjusted stably while taking a wide space from the buffer material 23b.

  As described above, the installation rail 13 and the stand / connection portion 23 provided on the lower surface of the display device 1 support the display device 1. Therefore, if there is a small space between the display device 1 and the stand / connection portion 23, the display device 1. Can be placed.

  Further, since the elevation angle X is adjusted by the stand and connecting portion 23, the elevation angle X direction of the display device 1 can be adjusted with a simple structure and a small space.

  Further, since the support column 25 is not required, it can be easily moved to a high position such as on a table and the elevation angle X can be adjusted.

  Further, as shown in FIG. 6, the display device 1 can be used as a wall-hanging TV by not using the stand and connecting portion 23 as a stand but using the gripping portion 17 as an attachment portion for hanging on the wall 31. In this case, since the hook 33 is engaged with the apex portion of the arc by forming the grip portion 17 in an arc shape, the display device 1 is not tilted and a stable posture can be maintained.

  In the case where the stand and connecting portion 23 appears to protrude from the bottom portion 1b of the display device 1 when it is hung on the hook 33 as it is from the state of FIG. As shown in FIG. 8, the stand-and-connecting portion 23 is protruded (exposed) from the bottom-side portion 1b by rotating the stand-and-connecting portion 23 about the rotation shaft portion 21 to the upper side of the display device 1 approximately 180 degrees. ) Can be suppressed, and the appearance can be prevented from being damaged. Moreover, the elevation angle of the display device 1 in the wall-mounted state can also be adjusted by controlling the rotation amount of the stand and connecting portion 23 around the rotation shaft portion 21 in a state where the display device 1 is wall-mounted.

  Here, if the dimension in the depth direction of the display device 1 of the first rotation shaft portion 21 is designed to be larger than the dimension in the depth direction of the display device 1 at the distal end portion of the grip portion 17, it is used as a wall-mounted TV. In this case, the display device 1 has a depression angle and is easy to see from below when hung on the top of the wall, which is suitable as a wall-mounted TV. At this time, the stand and connecting portion 23 functions as an angle adjusting portion that adjusts the elevation angle or depression angle of the display device 1.

  Moreover, if the front-end | tip part of the holding part 17 protrudes from the upper end part of the front side frame 1a like FIG. 7, it is suitable as wall hanging TV.

  Further, in the relationship between the wall-mounted TV and the second usage pattern, the stand / connection portion 23 functions as a stand / angle adjustment portion.

  In addition, since the 1st rotation axis | shaft part 21 is located below the center position regarding the length of the insertion / removal direction H with respect to the stand support | pillar part 30 of the display apparatus 1, it stands around the rotation axis part 21 as a center. Even if the cum connecting portion 23 is rotated by approximately 180 degrees, the stand cum connecting portion 23 does not protrude above the display device 1.

  In the stand-type thin television according to the first embodiment described above, the rotation of the display device 1 in the horizontal direction Y has been described by means for enabling the connecting body 15 to rotate with respect to the support column 25, but the present invention is limited to this. A second embodiment in which the display device 1, the connecting body 15, and the support column 25 rotate with respect to the horizontal direction Y with respect to the stand base 29 will be described below.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same part as above-described structure, the description is abbreviate | omitted, and it demonstrates centering on a different part from the said embodiment. The difference from the above-described embodiment is that the cross-sectional shape of the stand and connecting portion is changed from a circular shape to a substantially rectangular shape or the like (FIGS. 9 and 14). The shape is changed (FIGS. 9 and 14), the column can be rotated in the horizontal direction Y with respect to the stand base (FIG. 9), and the remote control device 53 of the display device 1 is held in the grip portion 17. The remote control holder 51 is provided (FIGS. 15 to 17). Details will be described below.

  The stand and connecting portion 35 according to the present embodiment includes a rotating portion 35a that is rotatably held by the first rotating shaft portion 21 at a base end portion, and a distal end that is the other end side of the rotating portion 35a. It has an anti-slip and shock-absorbing material 35b that functions as an anti-slip and shock-absorbing material formed of rubber, silicon, etc. on the side, and is long in the direction of the rotation axis (support axis direction) of the first rotation shaft portion 21 It is formed in a surface shape, for example, a substantially rectangular shape.

  By making the stand and connecting portion 35 have a rectangular cross section that is long in the rotating shaft direction of the first rotating shaft portion 21, the dimension of the connecting body 15 in the depth direction D1 (FIG. 10) of the display device 1 is reduced. The stability for supporting the display device 1 in the second usage pattern (when separated from the stand column 30) can be increased. That is, in the case of the stand and connecting portion 23 of the first embodiment, the contact portion with the installation location in the second usage pattern is the shape surrounded by the installation rail 13 and the antiskid / buffer material 23b. In the case of the stand and connecting portion 35 of the second embodiment, the anti-slip / buffer material 35b rotates the first rotary shaft 21 compared to the anti-slip / buffer material 23b. Since it is long in the axial direction (longitudinal direction of the lower part of the display device 1), the shape surrounded by the installation rail 13 and the anti-slip / buffer material 35b is such that the long side is between the installation rails 13 and the short side is non-slip / buffer In the case of a quadrangular or trapezoidal shape that is the length of the material 35b and the same inclination with respect to the display device 1, the stand and connecting portion 35 has a larger area for supporting the display device 1 and is more stable.

  As shown in FIGS. 9 and 10, the length of the stand and connecting portion 35 in the longitudinal direction (the direction from the base end portion to the distal end side) is the same as the length of the stand and connecting portion 35 in the liquid crystal display 3. In a state of being parallel to each other, the display device 1 is formed to have a length that is equal to or longer than the bottom 1b of the front frame 1a (including the same length). In the present embodiment, the length from the front side frame 1a of the display device 1 to the bottom side 1b is 113 mm and the protruding amount is about 19 mm from the bottom side 1b. Therefore, the state of FIG. 10B is seen from the front. As shown in FIG. 9, the stand and connecting portion 35 has a length that extends below the bottom side 1 b of the front frame 1 a.

  As shown in FIG. 14, the column 37 according to the present embodiment has an elliptical cross-sectional outer shape, and is provided with an insertion hole 39 that is similar to the substantially rectangular shape of the cross-section of the stand and connecting portion 35.

  The insertion hole 39 is a hole having a substantially rectangular cross section. When the stand / connection portion 35 is inserted, the anti-slip / buffer material 35b of the stand / connection portion 35 abuts against the bottom of the insertion hole 39 and the stand / connection portion. 35 is supported. Further, the size of the cross section of the insertion hole 39 is formed such that the inserted stand and connecting portion 35 does not cause unpleasant rattling and the stand and connecting portion 35 can be inserted and removed. Accordingly, the turning force in the horizontal direction of the display device 1 is transmitted to the support column 37 via the connecting body 15 and the stand / connecting portion 35.

  Since the support 37 and the stand base 45 can be rotated in the horizontal direction Y, the fitting 41 and the fitting 43 are similar to the fittings 105 and 106 shown in the prior art. The fitting fitting 41 and the fitting receiving fitting 43 are made into shapes that engage with each other so as to be rotatable.

  In addition, a smooth member 47 is provided at the bottom of the support 37 on the side of the stand base 45 in order to suppress generation of unpleasant frictional noises and the like when rotating with the stand base 45 and to prevent contact scratches. The smooth member 47 can be appropriately selected in relation to the material of the stand base 45. For example, plastic, hard rubber, silicon, or the like can be used.

  As shown in FIG. 9, the connecting portion between the support column 37 and the stand base 45 is rotated as shown in FIG. 9 in order to realize smooth rotation of the support column 37 and suppress frictional noise and contact damage when the stand base 45 rotates. The gap 49 is formed so as to increase as the distance from the center fitting fitting 41 and fitting receiving fitting 43 increases. The stand base 45 has a size capable of supporting the display device 1 at a predetermined height via the support column 37 and the connecting body 15.

  In the present embodiment, as shown in FIGS. 15 to 19, a remote control holder 51 that holds the remote control device 53 of the display device 1 is provided in the grip portion 17. Since the display device 1 of the present embodiment can be used separately from the support column 37, there is a possibility that the display device 1 and the remote control device 53 are also separated from each other. By providing the remote control holder 51 on the gripping portion 17 to be attached, the remote control device 53 can be attached to the destination, so that accidental misplacement or loss of the remote control device 53 can be avoided in advance.

  As shown in FIG. 18, the remote control holder 51 in the present embodiment has an attachment portion 51 a attached to the display device 1 side and two claw pieces 51 b shaped to be able to be engaged with and held by the remote control device 53. Yes.

  Specifically, when the remote control device 53 has a shape in which the distal end 53a is greatly narrowed to the other end 53b as shown in FIG. 19, the remote control device 53 is shaped to be narrowed as shown in FIG. When the two claw pieces 51b are engaged with each other by being inserted from the end 53b side, they are caught on the larger tip 53a side, and are engaged as shown in FIG. In this case, the distance between the claw pieces 51b-51b of the remote control holder 51 is set to a shape having an appropriate inclination so as to be narrowed from the upper side to the lower side of the display device 1, so that the remote control device 53 has a narrow shape. This is desirable because of better fit.

  Further, when the remote control holder 51 is formed using a material having moderate flexibility such as plastic, and the remote control device 53 is formed into a shape that can be clamped between the two claw pieces 51b-51b, When a slight force is applied to the control device 53 in the direction of insertion into the remote control holder 51, the claw piece 51 b breaks and the remote control device 53 can be brought into a narrow pressure engagement state in the remote control holder 51.

  If the claw piece 51b of the remote control holder 51 is designed to be slightly tightened when the remote control device 53 is held, the shape of the remote control device 53 is enlarged at the tip (53a side) or the other end (53B side). There is no need to make it narrow, and the remote control device 53 of various shapes can be held.

  The shape and mounting position of the remote control holder 51 are not limited, and may be directly mounted on the back surface of the display device 1. Any shape, form, and location that can move the remote control device 53 together with the display device 1 may be used. Further, any shape may be used as long as it can be fitted with the remote controller. The remote control device 53 may be fitted to the display device 1 itself so that it can be carried at the same time.

  As mentioned above, although a structure and an effect were demonstrated centering on the difference in 2nd Embodiment, it cannot be overemphasized that the effect described in 1st Embodiment is also show | played.

  In addition, although the said stand and connection part 35 demonstrated the cross section substantially rectangular shape long in the rotation axis direction of the 1st rotation shaft part 21, it is not limited to a cross section substantially rectangular shape, A stand and connection is carried out. Any shape can be used as long as the rotation of the portion 35 can be transmitted to the support column 37.

  Further, although the remote control holder 51 has been described in the second embodiment, it goes without saying that the remote control holder 51 can also be applied to the first embodiment.

  In the first and second embodiments, the stand and connecting portions 23 and 35 are pulled out from the insertion holes 27 and 39. However, the stand and connecting portions 23 and 35 are prevented from coming off from the insertion holes 27 and 39. A rod-shaped connecting pin (not shown) can be formed so as to penetrate the support columns 25 and 37 and be inserted into the stand and connecting portions 23 and 35. By adopting such a configuration, it is possible to move the display unit 1 to the stand bases 29 and 49 as a unit by lifting the grip portion 17. Needless to say, the means for preventing the disconnection is not limited to the method of inserting the connecting pin. This will be described in more detail as a third embodiment.

[Third Embodiment]
Hereinafter, a third embodiment of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same part as above-described structure, the description is abbreviate | omitted, and it demonstrates centering on a different part from the said 2nd Embodiment. The difference from the second embodiment is that the stand and connecting portion is provided with a recess 59 for preventing removal and a protrusion 61 for restricting the insertion direction so that the length is parallel to the liquid crystal display 3. In this state, the length is changed to a length equal to or less than the length (including the same length) to the bottom side 1b of the front frame 1a of the display device 1 (FIGS. 20 and 21) to prevent the stand and connecting portion from coming off. A mechanism is provided on the support (FIGS. 20 to 24), and a protrusion 55 is provided on the first rotating shaft 21 in order to restrict the elevation angle of the display device 1 when the support is connected to the stand / connector and after connection. The upper end shape of the column is changed (FIGS. 20 and 21), and a notification mechanism for an angle recommended as the elevation angle of the display device 1 is provided between the first rotating shaft portion 21 and the stand / connection portion (FIG. 25). It is in. Details will be described below.

[Stand and connecting part 57]
The stand and connecting portion 57 according to the present embodiment has a substantially rectangular cross-sectional shape like the stand and connecting portion 35, but the length of the stand and connecting portion 57 is the same as that of the bottom side 1 b (installation rail 13) of the front frame 1 a of the display device 1. The length does not exceed (including the same length) and is at least long enough to support the display device 1 as a stand in the second usage pattern. By setting the stand and connecting portion 57 to such a length, the center of gravity of the display device 1 in the second usage pattern is hung on the stand and connecting portion 57 side (the back side cover side), and the stand and connecting portion 57 falls. Even if an external force is applied, the display device 1 can be reliably prevented from being damaged by merely falling over to the back cover 7 side.

  The stand / connector 57 is provided with a recess 59 (FIG. 20) for preventing it from being connected to the support 65 and a restricting protrusion 61 (FIG. 21) for restricting the insertion direction to the support 65 in one direction. ing.

[Stand and connecting part side slip prevention mechanism]
A recess 59 (FIG. 20) is provided on the back side of the surface facing the display device 1 with the anti-slip / buffer material 35b of the stand and connecting portion 57 facing the bottom side 1b of the display device 1. In addition, it is formed from the free end side (slip prevention / buffer material 35b side) in the longitudinal direction (rotating portion 35a-slip / buffer material 35b direction). The shape of the drop-out prevention recess 59 is a substantially triangular prism shape that is long in the width direction of the stand and connecting portion 57, and the depth of the recess is gradually deepened toward the free end side (the anti-slip / buffer material 35b side). is doing.

[Insertion restriction mechanism]
The restricting protrusion 61 (FIG. 21) is formed on the back side of the recess 59 for preventing the stand and connecting portion 57 from being removed, and is perpendicular to the direction in which the stand and connecting portion 57 is inserted into the support column 65 (when abbreviated as “inserting vertical direction”). It is a mountain-shaped, convex-shaped part extending to The restricting projection 61 is an example of an insertion restricting mechanism that restricts the insertion direction of the stand and connecting portion 57 to the support column 65 in one direction, and is not limited to the position and shape of the restricting projection 61. When the insertion restricting mechanism is formed by, for example, a protrusion or a groove (a dent, a dent, or a notch), a protrusion having a mountain shape, a convex shape, or the like in a direction perpendicular to the insertion direction in a portion inserted into the column 65 of the stand / connector 57 The cross-sectional shape of the stand-and-connecting portion 57, that is, the cross-sectional shape that restricts the shape inserted into the support column 65 in one direction, such as a trapezoidal cross-section, may be formed. May be.

  By providing the insertion restricting mechanism as described above, the display device 1 is positioned in an unexpected direction, so that it is possible to obtain an unbalanced first usage pattern or to prevent a fall. That is, the stand base 45 (FIG. 21) has a shape that protrudes more toward the display surface than the rear side of the column 65 in order to prevent the column 65 having a center of gravity on the display device 1 from falling down. If the stand and connecting portion 57 is inserted in the opposite direction to 65, there is a possibility of falling, so that the possibility of falling can be reliably eliminated by providing an insertion restricting mechanism.

[Rotation restricting member]
In order to restrict the elevation angle of the display device 1 when the column 65 and the stand / connection portion 57 are connected and after the connection, a protrusion 55 is provided on the first rotating shaft portion 21 (FIGS. 20 and 21).

  The protrusion 55 is formed on the first rotation shaft portion 21 with a predetermined length in the rotation direction of the stand and connection portion 57. In the present embodiment, the surface of the first rotation shaft portion 21 where the protrusion 55 is not formed is formed in a substantially semicircular shape equidistant from the rotation shaft center of the stand and connecting portion 57, thereby forming the protrusion 55. In this portion, the distance from the rotation axis of the stand and connecting portion 57 is made longer than the portion where the protrusion 55 is not provided, so that the removal preventing mechanism does not function normally when the protrusion 55 interferes with the column 65. It becomes an unstable posture and can inform the user that the attachment is in a posture exceeding the allowable range.

  In addition, even when the first use mode in which the removal prevention mechanism functions normally is performed, the lower side surface 55a of the protrusion 55 is the upper surface 69 of the support column 65 in the case of tilting in the elevation direction so as to be in an unstable balance state. It interferes with and collides with the rear edge 69a (FIG. 21), and further rotation in the elevation angle direction is restricted, so that unbalanced use in the first usage pattern can be prevented.

  Further, the projection 55 is engaged with or close to the upper surface 69 of the support column 65, and is provided on a portion that rotates in synchronism with the display device 1, for example, the first rotation shaft portion 21, whereby the second usage pattern. Without restricting the elevation angle of the display device 1 in the above, it is possible to realize posture regulation when shifting to the first usage pattern and unreasonable rotation regulation of the display device 1 in the first usage pattern. As a result, the elevation angle change allowable range of the display device 1 in the first usage pattern and the allowable range in the second usage pattern can be different from each other, and a safe use according to the usage pattern can be ensured.

  In addition, as a means for realizing the restriction, it is sufficient if the distance from the rotation shaft of the stand and connecting portion 57 to the surface of the first rotation shaft portion 21 is different (longer distance of the restriction range), for example, A similar effect can be obtained by forming the surface of the first rotation shaft portion 21 in an ellipse or the like instead of the projection 55. In the present embodiment, the protrusion 55 or the protrusion 55 and the rear edge 69a of the column 65 are formed so that the inclination angle from the vertical direction of the installation surface of the display device 1 can be inclined by about 10 degrees.

[Grip part 17b]
The display device 1 includes a gripping portion 17b for easy carrying. The gripping part 17b may be anything that can be gripped. In the present embodiment, in order to facilitate the insertion / removal of the column 65 and the stand / connecting portion 57, the gripping portion 17 b has a smaller inclination angle with respect to the fixed portion 19 than the gripping portion 17. Thereby, since the display apparatus 1 does not shake when the holding part 17b is held, the first and second usage forms can be easily and smoothly shifted.

  Further, the gripping part 17b is convenient for carrying and wall hanging if it is a circular shape, but a rectangular shape is also suitable for carrying and a triangular shape for wall hanging.

[Prop 65]
The strut 65 differs from the strut 37 of the second embodiment in terms of the shape of the upper surface 69, the shape of the insertion hole 71, the opening / closing lid 73, the stand-off connecting mechanism 57 and the like prevention mechanism 77. (FIGS. 20 to 24).

  The upper surface 69 of the column 65 is formed so as to gradually increase in height from the display surface side of the display device 1 toward the back surface side so as to engage with the lower surface of the first rotation shaft portion 21. ing. With such a shape, the gap between the support column 65 and the first rotation shaft portion 21 can be reduced in the first usage pattern, and the separable display device 1 side and the support column 65 side can be given a sense of unity. Can be excellent. Further, when the stand and connecting portion 57 is inserted into the support column 65, when the projection 55 is in contact with the upper surface 69, the upper surface 69 and the lower surface of the first rotating shaft portion 21 are uneven. Since a gap occurs without matching, it is possible to make the user recognize that the insertion is inappropriate.

  The insertion hole 71 is a hole into which the stand / connection portion 57 is inserted, and is formed in a shape substantially similar to the cross-sectional shape in the insertion vertical direction of the stand / connection portion 57 provided with the regulation protrusion 61 (FIG. 22).

[Interference prevention member]
In the insertion hole 71, cushioning materials 72a and 72b made of rubber, plastic, silicon or the like in the form of blocks, rods, and / or plates, etc., are inserted into the insertion hole 71 as interference preventing members that maintain a predetermined gap with the stand / connecting portion 57. It is provided on the opening side from the longitudinal center in 71. The buffer materials 72a and 72b may be provided annularly or partially with respect to the insertion vertical direction. The stand and connecting portion 57 inserted into the insertion hole 71 is supported in the insertion hole 71 by way of cushioning materials 72a and 72b on the shaft side surface and the anti-slip / buffering material 35b on the tip side. Therefore, unpleasant wobble and interference sound of the display device 1 with respect to the support column 67 can be reduced.

  Further, by forming a portion 89 or the vicinity of the anti-slip / buffer material 35b of the stand and connecting portion 57 in the insertion hole 71 with a magnet, and forming the anti-slip / buffer material 35b with metal, In the first mode of use, unpleasant wobble and interference sound of the stand and connection portion 57 in the support column 67 can be reduced by attracting the tip of the stand and connection portion 57 to the magnet at the bottom of the insertion hole 71.

[Cover member 73]
The open / close lid 73 is a lid member that is pivotally supported at one end side in the upper portion of the insertion hole 71 and is always biased in a direction to close the opening of the insertion hole 71 (FIGS. 22 and 23). In the second use state, the opening / closing lid 73 closes the opening of the insertion hole 71, so that the dirt in the insertion hole 71 can be prevented.

[Protruding side prevention mechanism]
23 is a cross-sectional perspective view taken along the line BB in FIG. 22, FIG. 24 is a perspective view from the back side of the slip prevention mechanism 77 portion in FIG. 23, and FIG. 25 presses the operation unit 79 from the state of FIG. It is a perspective view explaining the effect | action of the drop prevention mechanism 77 at the time.

  As shown in FIG. 23, the removal preventing mechanism 77 is inserted into the recess 59 for preventing removal (FIG. 20) with the user's operation unit 79 in the first use state, and is engaged with the projections and depressions to operate the operation unit 79 (for example, And the insertion / extraction portion 85 for releasing the engagement of the concave and convex portions, the frame 81 for accommodating the operation portion 79 and the insertion / extraction portion 85 so as to be slidable back and forth, and the operation portion 79 and the insertion / extraction portion. 85 are formed by springs 83 and 87 for urging 85 from the frame 81 outward.

  The operation unit 79 has a chamfered operation button with a recessed center in order to increase the contact surface with the finger and disperse the pressing force, and the portion inserted into the removal prevention recess 59 of the insertion / extraction unit 85 is prevented from being removed. The shape of the recess 59 is similar to a substantially triangular prism shape. The sliding direction of the operation unit 79 and the insertion / extraction unit 85 in the frame 81 is substantially vertical to each other, and the biasing directions of the springs 83 and 87 are also substantially vertical.

  On the side wall of the frame 81, as shown in FIG. 24, a first guide hole 81a that guides the movement of the operation portion 79 in the movement direction, and a second guide hole 81b that guides the movement of the insertion / extraction portion 85 in the movement direction. The guide protrusion 79a of the operation portion 79 is engaged with the first guide hole 81a, and the link rod 85a of the insertion / extraction portion 85 is engaged with the second guide hole 81b so as to be reciprocally slidable.

  The operation unit 79 is provided with a link side 79b that is an inclined side that presses and displaces the link rod 85a along the second guide hole 81b as the operation unit 79 moves.

  With the above configuration, when the gripping portion 17b is pulled up in a state where the stand and connecting portion 57 is connected to the support column 65 (FIG. 23), the stand and connecting portion 57 that opposes the first interference surface 85c of the insertion / extraction portion 85 is removed. The second interference surface 59a of the prevention recess 59 interferes, and the support column 67 and the stand base 45 can be pulled up as a unit, and can be moved in the first use state.

  When shifting to the second use state, the operation projection 79 is pressed against the urging force of the spring 83, so that the guide projection 79a is formed in the first guide hole as shown in FIGS. When the link side 79b presses the link rod 85a while moving in 81a, the link rod 85a moves backward (in the direction in which the insertion / extraction portion 85 is pulled out from the removal-preventing recess 59) in the second guide hole 81d, and The insertion / extraction part 85 which forms the link rod 85a synchronously moves backward against the spring 87, and the insertion / extraction part 85 is pulled out from the inside of the removal prevention recess 59. The first interference surface 85c of the insertion / extraction portion 85 does not interfere with the second interference surface 59a by pulling up the gripping portion 17b while the operation portion 79 is pressed in the insertion direction H1 of the stand / connection portion 57. The stand and connecting portion 57 is pulled out from the above. At this time, a force is applied to the operation portion 79 in the insertion direction H1 of the stand / connection portion 57 to prevent the support portion from lifting, and the grip portion 17b is lifted to lift the stand / connection portion 57 from the stand support portion. Since a force acts in the separation direction H2, a reaction force is applied to facilitate removal and stable removal.

[Notification mechanism]
FIG. 25 shows the sounding portion 91 provided on the first turning shaft portion 21 (FIG. 20) and the turning portion 35 a of the stand / connection portion 57 as an example of a recommended elevation angle notification mechanism of the display device 1. Yes.

  The sound generating portion 91 is engaged with a roller 93 rotatably provided in a long hole 22 c (FIG. 25B) provided in the bearing portion 22 fastened to the first rotating shaft portion 21, and the roller 93. The plate-shaped roller receiving part 95 provided with the notches 94a and 94b, and an urging means 97 for always urging the roller 93 toward the roller receiving part 95 are configured.

  The bearing portion 22 includes a fastening surface 22a fastened to the first rotation shaft portion 21 by screwing or the like, a shaft support surface 22b that supports the rotation shaft 36 of the rotation portion 35a, and the shaft support surface 22b. A long hole 22c that allows the roller 93 to rotate freely is provided.

  The long hole 22c is close to the bearing 22d of the rotating shaft 36 and is located at a position facing the notches 94a and 94b. The short diameter loosely fits the roller 93 with a predetermined gap. The movement of the roller 93 in the longitudinal direction of the long hole 22c is regulated by the bearing 22d at one end side and by the base end portion 97a of the biasing means 97 at the other end side. It should be noted that the long hole 22c only needs to have a size and shape so that at least the roller 93 can swing in the biasing direction upon receiving the biasing force of the biasing means 97.

  The roller 93 uses a sphere, but may have a rotatable shape, for example, a cylindrical shape or a conical shape. The roller 95 is made of metal, but any material such as metal or resin may be used in consideration of the rotational contact sound with the roller receiving portion 95 and the notification sound when engaged with the notches 94a and 94b. You can choose.

  The roller receiving portion 95 is a plate-like member that protrudes in a bowl shape from the rotation shaft 36 that is pivotally supported by the shaft support surface 22b, and is a notch 94a that is notched in a ring shape at a substantially equal distance from the rotation shaft 36. , 94b. Although the roller receiving portion 95 is formed in a flat plate shape, by providing a guide rail of the roller 93 at a contact portion with the roller 93, the roller receiving portion 95 can be guided in the moving direction of the roller 93 and can be smoothly rotated. For example, the guide rail can be formed by a groove having a width capable of guiding the roller 93.

  The notches 94a and 94b have an opening through which the roller 93 does not pass, and are formed in a ring shape having a diameter smaller than the diameter of the roller 93 in order to increase the stability of the engaged roller 93, whereby the centering of the roller 93 is performed. The effect is gained. Further, a curved surface (contact surface) 94c that engages with the roller 93 is formed on the opening edges of the notches 94a and 94b so that the stability and centering of the roller 93 that engages with the notches 94a and 94b are formed. Increases the effect.

  The notch 94a has a recommended angle for connecting the stand and connecting portion 57 to the support column 65 when the second using mode is changed to the first using mode, that is, the stand and connecting unit 57 is connected to the display device 1. The roller 93 is provided at a position facing the roller 93 when substantially parallel (approximately 0 degrees), and the notch 94b is displayed with respect to the recommended inclination angle of the display device 1, for example, the vertical direction of the installation surface in the second usage pattern. The roller 93 is provided at a position facing the roller 93 when the display screen of the device 1 is inclined at about 15 degrees. Note that the number and positions of notches are not limited to this, and can be arbitrarily changed according to an event that the user wants to know as a recommended angle.

  The urging means 97 constantly urges the roller 93 toward the roller receiving portion 95, and the base end portion 97a is fastened with a screw 99 on the roller receiving portion 95 side of the shaft supporting surface 22b. The abdomen surface 97b in the vicinity of the free end presses the roller 93 against the roller receiving part 95 with a predetermined urging force.

  With the above configuration, when the stand and connecting portion 57 is axially rotated from the state in which the roller 93 is engaged with the notch 94 a, the rotation shaft 36 and the roller receiving portion 95 also have the urging force that the roller 93 receives from the urging means 97. Rotating against the centering force between the roller 93 and the notch 94a, the roller 93 rolls on the flat surface of the roller receiving portion 95 and receives from the biasing means 97 when it engages with the curved surface 94c of the notch 94b. A notification sound is generated to tell the recommended angle with the “click” due to the force and the centering force between the roller 93 and the notch 94b. Therefore, since the user is notified of the recommended angle, the user can know that the use is safe, and the user-friendly device can be obtained. The rotation from the notch 94b to the notch 94a is the same, and the angle of the stand and connecting portion 57 to be inserted into the support column 65 can be known by a notification sound that tells the recommended angle with the “click”. Recognize that the angle is safe.

  The biasing means 97 is not limited to a leaf spring, and may be an elastic member that constantly presses the roller 93 against the roller receiving portion 95, such as rubber.

  In addition, the configuration in which the recommended angle is audibly notified to the user as the notification mechanism, for example, the sound generation unit 93 has been described. However, the configuration is not limited, and any configuration may be used as long as the sound can be output in accordance with the angle change. In addition, the same effect can be obtained by visually informing the user of the recommended angle by using, for example, the light emitting element and the light emitting member.

  Needless to say, the same effects can be obtained by applying the configuration of the third embodiment to the configuration of the first embodiment.
