  However, the display device disclosed in Patent Document 1 has a tendency to increase in size because the stopper is rotated by the rotation of the display device.

  Therefore, an object of the present invention is to make it possible to regulate the position of the display unit in the height direction according to the rotation state of the display unit with a compact configuration as much as possible.

  In order to solve the above problems, the rotary display device includes a first housing having a display unit, a second housing, a rotation support mechanism that rotatably supports the first housing, and the second housing. A height direction fixed side member provided on the body side, and a height direction movable side member provided on the rotation support mechanism side, and the rotation support mechanism and the first case with respect to the second case. A height adjustment mechanism that supports the body so that the height of the body can be adjusted, and a height that can be moved in the height direction along with the height adjustment of the first housing and that can be rotated along with the rotation of the first housing. An adjustment restriction shaft and a height adjustment restriction member provided on the height direction fixed side member side, and at least a part of the height adjustment restriction shaft is formed in a non-circular cross-sectional shape part, The height adjustment restriction shaft has a height adjustment restriction shaft in a height adjustment non-restriction range. In the state where the non-circular cross-section portion can be rotatably arranged and the height adjustment restriction shaft is in the height adjustment restriction range, the non-circular cross-section portion is arranged at a predetermined rotation angle posture. A height adjustment restriction mechanism in which a height adjustment restriction groove is formed in which a restriction portion that can be provided is continuous along the height direction.

  According to the rotary display device configured as described above, the non-circular cross-sectional portion of the height adjustment restriction shaft is high when the height adjustment restriction shaft is in a predetermined rotation posture as the first casing rotates. It is movable along the non-regulating part and the restricting part of the height adjustment regulating groove. For this reason, in the said state, a height adjustment control shaft can be moved to a height direction, and the said rotation support mechanism and the said 1st housing | casing can be height-adjusted. On the other hand, when the height adjustment restriction shaft rotates with the rotation of the first housing and is not in a predetermined rotation posture, the non-circular cross-section portion of the height adjustment restriction shaft can be disposed in the restriction portion of the height adjustment restriction groove. Therefore, it cannot be disposed in the non-regulated portion. Thereby, the movement range of the height adjustment restriction shaft in the height direction is restricted, and the height adjustment range of the rotation support mechanism and the first housing can be restricted. Thereby, the position of the height direction of a display part can be controlled according to the rotation state of a display part. Further, since the height adjustment regulating shaft is a shaft that rotates around the axis, it can be configured as compact as possible.

A rectangular display unit 22 having one set of opposite sides longer than the other set of opposite sides is incorporated in one main surface side portion of the first housing 20. The display unit 22 is a thin display unit such as a liquid crystal display unit, an organic EL display unit, or a plasma display.

  The second housing 30 is a housing for supporting the first housing 20 via the rotation support mechanism 40. The height adjustment mechanism 80 is configured as a stand for supporting the first housing 20 in an upright manner. That is, the height adjustment mechanism 80 includes a placement unit 32 that is placed on the floor surface, a desk, or the like, and a back support unit 34 that protrudes upward from the placement unit 32.

  The second housing 30 includes a circuit unit having a power supply circuit and various processing circuits for processing image signals, and inputs / outputs various signals to / from the rotary display device 10. Input / output terminals and the like are provided (both not shown).

  But the 2nd housing | casing and the height adjustment mechanism 80 are not restricted to the structure supported by mounting on a floor etc., The structure etc. which are carried by hand etc. may be sufficient. Here, the vertical direction and the horizontal (left-right) direction are defined based on a normal use state such as a state where the second casing is placed on the floor or the like or a state where the second case is held by hand.

  The rotation support mechanism 40 is interposed between the first housing 20 and the second housing 30 and is configured to rotatably support the first housing 20. Here, in the normal use state, a state in which the long side of the first housing 20 is disposed along the substantially horizontal direction is referred to as a horizontally long state, and the long side of the first housing 20 is disposed along the vertical direction. The installed state is called a vertically long state.

  The height adjustment mechanism 80 is interposed between the second housing 30 and the first housing 20, the rotation support mechanism 40, and the second housing 30 between a predetermined lowermost position and a predetermined uppermost position. It is configured to support the height adjustable between them.

  That is, in the rotary display device 10, the first housing 20 having the display unit 22 is rotatably supported by the rotation support mechanism 40 so as to be switched between the horizontally long state and the vertically long state, and rotates with the first housing 20. The support mechanism 40 and the second housing 30 are supported by a height adjustment mechanism 80 so that the height can be adjusted.

  In addition, the height adjustment restriction mechanism 100 is configured to restrict the height adjustment range by the height adjustment mechanism 80 according to the rotation posture of the first housing 20. Here, the height adjustment restricting mechanism 100 adjusts the height by the height adjustment restricting mechanism 100 so that the first case 20 is disposed at the lowest position when the first case 20 is in the vertically long state. And the height adjustment restriction by the height adjustment restriction mechanism 100 so that the first case 20 can be moved between the lowermost position and the uppermost position. Is to be canceled.

  Hereinafter, for convenience of description, the configuration related to the rotation support mechanism 40 will be mainly described, and then the configuration related to the height adjustment mechanism 80 and the height adjustment restriction mechanism 100 will be described.

  2 is a front view showing the rotary display device 10 in the horizontally long state, FIG. 3 is a front view showing the rotary display device 10 in the vertically long state, and FIG. 4 is a state between the horizontally long state and the vertically long state ( It is a front view which shows the rotary type display apparatus 10 in the state rotated 45 degree | times from the horizontally long state). 2 to 4, for convenience of explanation, the configuration related to the height adjustment mechanism 80 and the height adjustment restriction mechanism 100 is omitted, and the configuration related to the rotation support mechanism 40 is mainly illustrated.

  As shown in FIGS. 1 to 4, the rotation support mechanism 40 includes a first housing side support member 50, a second housing side support member 60, a rotation center side guide pin 70, and a rotation restriction side guide pin 75. Have. The first housing side support member 50 is a member attached to the surface of the first housing 20 on the second housing 30 side (that is, the back surface), and the second housing side support member 60 is the second housing. 30 is a member attached to the surface (namely, the front surface) on the side of the first housing 20. Then, the first housing side support member 50 and the second housing side support member 60 are rotatably connected via the rotation center side guide pin 70 and the rotation restriction side guide pin 75, so that the second housing 30. In contrast, the first housing 20 is rotatably supported.

  More specifically, the first housing-side support member 50 is a member formed of a metal plate or a resin plate that has been punched or bent, and is substantially parallel to the main surface of the first housing 20. And a first housing side flat plate portion 51 facing the second housing 30 side. Further, the second housing side support member 60 is a member formed by a punched or bent metal plate, a resin plate or the like, and is substantially parallel to the main surface of the first housing 20 and is the first. It has the 2nd housing | casing side flat plate part 61 which faces the housing | casing 20 side. In the horizontally long state and the vertically long state, the first housing side flat plate portion 51 and the second housing side flat plate portion 61 are disposed to face each other so as to overlap at least partially.

  The second housing side flat plate portion 61 is formed with an upper and lower guide groove 62 and a rotation restricting guide groove 64.

  The vertical guide groove 62 is formed as a slit-like groove extending in the vertical direction, and is formed in an upper portion of the second housing side flat plate portion 61 here. The upper and lower guide grooves 62 mainly serve to regulate the upper position and the lower position of the first housing 20.

  The rotation restricting guide groove 64 is non-parallel to the upper and lower guide grooves 62, here, extends in an oblique direction, and is provided around the upper and lower guide grooves 62. Here, the rotation restricting guide groove 64 is formed as a slit-like groove extending in a linear direction in contact with a virtual circle C surrounding the upper and lower guide grooves 62. Here, the rotation restricting guide groove 64 is formed in a region extending from one side portion of the upper and lower guide groove 62 to the lower portion of the second housing side flat plate portion 62, and from the upper and lower guide groove 62 upward. It is formed so as to incline in the direction of leaving. As will be described later, the inclination angle of the rotation restricting guide groove 64 is moved along the upper surface of the mounting portion 32 at the lower corner portion on one side when the first housing 20 is rotated while being lifted upward. It is set to an angle that can be caused. The rotation regulation guide groove 64 also has a role of regulating the position of the horizontally long state and the vertically long state when the first housing 20 is rotated.

  The virtual circle C with which the rotation restricting guide groove 64 is in contact may be any circle as long as it surrounds the upper and lower guide grooves 62. Further, the extending direction of the rotation restricting guide groove 64 is not limited to the above example. For example, when the vertical guide groove is formed in the lower portion of the second housing support member and the rotation restriction guide groove is formed in a region extending from the side of the vertical guide groove to the upper portion, the rotation The restriction guide groove may be formed so as to incline downward in a direction away from the upper and lower guide grooves.

  The first casing side flat plate portion 51 is formed with a sub vertical guide groove 52 and a sub rotation restricting guide groove 54.

  The sub vertical guide groove 52 extends above the vertical guide groove 62 while rotating the first housing 20 with respect to the second housing 30, and with respect to the vertical guide groove 62 in other intermediate states. It is formed as a linear slit-like groove that can cross diagonally. Here, in the horizontally long state and the vertically long state, the auxiliary vertical guide groove 52 extends obliquely 45 degrees downward from the lower end portion of the vertical guide groove 62 and the first housing 20 is rotated 45 degrees from the horizontally long state. The upper and lower guide grooves 62 are formed in a position and posture extending upward from the upper end portion along the vertical direction.

  The sub-rotation restriction guide groove 54 extends in a direction intersecting the rotation restriction guide groove 64 in the middle of rotating the first housing 20 with respect to the second housing 30 and rotates in the horizontally long state or the vertically long state. The restriction guide groove 64 is formed in an arcuate slit groove shape extending from the lower end portion on one side. Here, the sub-rotation restriction guide groove 54 is an arc-shaped slit groove that is recessed on the side of the sub-upper and lower guide grooves 52 and protrudes on the opposite side. In the horizontally long state, the rotation restriction guide groove 64 extends from the lower end of the rotation restriction guide groove 64. In the vertically long state, it extends from the upper end of the rotation restricting guide groove 64 in a direction substantially perpendicular to the extending direction of the rotation restricting guide groove 64, and is in a horizontally long state or a vertically long state. In the middle of rotation, the position and posture intersect with the rotation restricting guide groove 64.

  The rotation center side guide pin 70 is slidably supported by the auxiliary vertical guide groove 52 of the first housing side support member 50 and is slidably supported by the vertical guide groove 62 of the second housing side support member 60. ing. As the rotation center side guide pin 70, for example, a pin-shaped member in which an annular groove capable of fitting the peripheral edge portion of the sub vertical guide groove 52 and an annular groove capable of fitting the peripheral edge portion of the vertical guide groove 62 is used. Can do. But the rotation center side guide pin 70 is not restricted to the said structure, What is necessary is just a structure which can be slidably arrange | positioned in the sub vertical guide groove 52 and the vertical guide groove 62. FIG. Further, when the sub vertical guide groove 52 is omitted, the rotation center side guide pin 70 may be provided in a protruding shape at a fixed position of the second housing side support member 60.

  The rotation center side guide pin 70 is urged toward one end side of the sub vertical guide groove 52 by a coil spring 74 which is a first urging member. Here, the coil spring 74 is provided on the upper end side extension of the auxiliary vertical guide groove 52 inside the first housing side support member 50, and each end thereof is supported by the rotation center side guide pin 70 and the first housing side support. The member 50 is attached to the inner surface portion in an extended state. Thus, the coil spring 74 constantly urges the rotation center side guide pin 70 toward the upper end side of the sub vertical guide groove 52.

  As the first urging member, a spring, a torsion coil spring or the like may be used in addition to the coil spring.

  The rotation restricting guide pin 75 is slidably supported in the sub-rotation restricting guide groove 54 and slidably supported in the rotation restricting guide groove 64. As the rotation restricting side guide pin 75, as in the case of the rotation center side guide pin 70, a configuration that can be arranged so as to be movable along the groove can be adopted.

  Further, the rotation restricting guide pin 75 is urged to one end side of the sub rotation restricting guide groove 54 by a coil spring 79 which is a second urging member. Here, the coil spring 79 is provided on the inner side of the first housing side support member 50 on the extension on the lower end side of the auxiliary rotation restriction guide groove 54 (on the extension of the end portion far from the rotation center side guide pin 70). Both ends thereof are attached to the rotation restricting guide pin 75 and the inner surface portion of the first housing side support member 50 in an extended state. Accordingly, the coil spring 79 constantly urges the rotation restricting guide pin 75 toward the lower end side of the sub rotation restricting guide groove 54. As the second urging member, a spring, a torsion coil spring or the like may be used in addition to the coil spring.

  In the present embodiment, the rotation center side guide pin 70 slides in the auxiliary vertical guide groove 52 during the rotation of the first casing 20, thereby rotating the rotation center side guide pin 70 on the first casing 20 side. And the rotation restricting guide pin 75 are changed.

  However, the distance between the guide pins 70 and 75 is changed by sliding the rotation restricting side guide pin 75 in the sub rotation restricting guide groove 54 during the rotation of the first housing 20. Also good.

  Further, during the rotation of the first housing 20, the distance between the guide pins 70 and 75 is changed by sliding both the rotation center side guide pin 70 and the rotation restriction side guide pin 75. May be. However, the direction of rotation of the first housing 20 is stabilized when one of the guide pins 70 and 75 is fixed. In the present embodiment, in consideration of this point, the rotation restricting guide pin 75 is fixed at a fixed position as much as possible during the rotation of the first housing 20.

  Further, the sub vertical guide groove 52 and the sub rotation restriction guide groove 54 are not essential, and the rotation center side guide pin 70 and the rotation restriction side guide pin 75 are supported at a fixed position with respect to the first housing side support member 50. Also good. In this case, for example, the rotation center side guide pin moves in the perspective direction with respect to the rotation restriction guide groove as the rotation restriction side guide pin moves in the rotation restriction guide groove due to the rotation of the first housing. The upper and lower guide grooves may be formed so as to be able to.

  The operation of the rotation support mechanism 40 will be described.

  First, in the horizontally long state, as shown in FIG. 2, the sub-upper and lower guide grooves 52 are connected in a diagonally downward direction from the lower end portion of the upper and lower guide grooves 62. Further, the sub-rotation restriction guide groove 54 is in a continuous state so as to extend from the lower end portion of the rotation restriction guide groove 64 along the outward direction of the rotation restriction guide groove 64. The rotation center side guide pin 70 is positioned at the lower end portion of the upper and lower guide grooves 62 and is positioned at the upper end portion of the auxiliary rotation restriction guide groove under the biasing force of the coil spring 74. Further, the rotation restricting guide pin 75 is located at the lower end of the rotation restricting guide groove 64, and against the urging force of the coil spring 79 by the weight of the first housing 20, at the upper end of the sub rotation restricting guide groove 54. It is in a position.

  When switching from the horizontally long state to the vertically long state, the first housing 20 is rotated while being lifted. Then, first, while the rotation center side guide pin 70 moves upward in the vertical guide groove 62 and moves downward in the sub vertical guide groove 52, the rotation restriction side guide pin 75 is subjected to rotation restriction under the urging force of the coil spring 79. The sub-rotation restricting guide groove 54 moves to the lower end of the guide groove 64 while being positioned at the lower end of the guide groove 64. Thereafter, the rotation center side guide pin 70 moves upward in the vertical guide groove 62 and moves downward in the sub vertical guide groove 52, while the rotation restriction side guide pin 75 is located at the lower end of the sub rotation restriction guide groove 54. It moves toward the upper side of the rotation restricting guide groove 64 while keeping the position.

  Then, as shown in FIG. 4, the first housing 20 is rotated upward by a predetermined angle (here, 45 degrees) in a predetermined direction (right rotation direction in FIG. 4). Then, the rotation center side guide pin 70 reaches the upper end portion of the vertical guide groove 62 along the vertical guide groove 62. At this time, the sub vertical guide groove 52 moves above the vertical guide groove 62 while changing the posture around the rotation center side guide pin 70. The sub vertical guide groove 52 extends linearly above the vertical guide groove 62. In this state, the rotation center side guide pin 70 is moved to the lower end portion in the sub vertical guide groove 52.

  On the other hand, the rotation restricting side guide pin 75 slides upward from the lower end portion of the rotation restricting guide groove 64 while being positioned at the lower end portion of the sub rotation restricting guide groove 54. As shown in FIG. 4, when the first housing 20 is at a predetermined angle, the rotation restricting guide pin 75 is located in the middle of the rotation restricting guide groove 64 in the longitudinal direction. At this time, the auxiliary rotation restriction guide groove 54 moves along the rotation restriction guide groove 64 and extends in a direction intersecting the rotation restriction guide groove 64.

  Thereafter, when the first housing 20 is further rotated while being moved downward, the rotation center side guide pin 70 is moved above the auxiliary vertical guide groove 52 under the biasing force of the coil spring 74 as shown in FIG. And move downward along the upper and lower guide grooves 62. In accordance with this, the rotation restricting side guide pin 75 moves upward along the rotation restricting guide groove 64. When the first housing 20 is rotated in the vertically long state, the sub vertical guide groove 52 is in a state of being connected obliquely downward from the lower end portion of the vertical guide groove 62, and the sub rotation restriction guide groove 54 is Thus, the rotation restriction guide groove 64 extends from the upper end portion toward the rotation center side guide pin 70 in a posture substantially orthogonal to the extending direction of the rotation restriction guide groove 64. In this state, the rotation center side guide pin 70 is positioned at the lower end portion of the upper and lower guide grooves 62, and is positioned at the upper end portion of the sub-rotation restriction guide groove under the bias by the coil spring 74. Further, the rotation restricting guide pin 75 is located at the upper end portion of the rotation restricting guide groove 64 and is located at the lower end portion of the sub rotation restricting guide groove 54 under the biasing force of the coil spring 79.

  The sub-upper / lower guide groove 52, the upper / lower guide groove 62, the sub-rotation restriction guide groove 54, and the rotation restriction guide groove 64 are placed on the lower corner portion of one side of the first housing 20 during the rotation operation. The inclination angle, the length dimension, the relative positional relationship, etc. are set so as to move along the upper surface of the portion 32.

  Since the first housing 20 can be rotated while being lifted upward in this way, the lower corner of the first housing 20 is not brought into contact with the placement portion 32, and the placement portion 32 is not touched. The first housing 20 can be rotated so as to move along the upper surface.

  Further, when rotating from the vertically long state to the horizontally long state, the operation is reversed.

  The structure which concerns on the height adjustment mechanism 80 and the height adjustment control mechanism 100 is demonstrated.

  As described above, the height adjustment mechanism 80 supports the rotation support mechanism 40, the first housing 20, and the second housing 30 so that the height can be adjusted. The height adjustment restriction mechanism 100 is configured to switch between a state in which the height adjustment is restricted and a state in which the restriction is released in response to an operation in which the rotation restriction guide pin 75 slides in the rotation restriction guide groove 64. Has been.

  The height adjustment mechanism 80 includes a height direction fixed side member 82 and a height direction movable side member 84 (see FIG. 1). The height direction fixed side member 82 is a substantially plate-like member attached and fixed to the back support portion 34, and has upper and lower grooves extending in the vertical direction. The height direction movable side member 84 is a member provided on the second housing 30 side, and can be moved up and down by the height direction fixed side member 82 and can be stopped at a predetermined height position. . Here, a pair of extending movable portions 85 extending from the height direction movable side member 84 to the back side are inserted into the upper and lower grooves of the height direction movable side member 84 so as to be vertically movable. . Such a height adjustment mechanism itself can be realized by various configurations including a known configuration such as a configuration using a rail and a movable body that moves the rail.

  As illustrated in FIG. 1, the height adjustment restriction mechanism 100 includes a height adjustment restriction shaft 110 and a height adjustment restriction member 130. The height adjustment regulating shaft 110 is configured to be movable in the height direction with the height adjustment of the first housing 20 and to be rotatable with the rotation of the first housing 20. Further, the height adjustment restricting member 130 is provided at a certain height position on the height direction fixed side member 82 side, and the height adjustment restricting shaft rotates according to the height position of the height adjustment restricting shaft 110. It is configured to be switchable to a state in which posture change is allowed and restricted.

  Here, the height adjustment restriction shaft 110 is configured to be able to change the rotation posture with the rotation of the first housing 20 by the restriction state switching member 120.

  5 is an exploded perspective view showing the height adjustment restriction shaft 110 and the restriction state switching member 120, FIG. 6 is a view showing the posture (non-regulation posture) of the restriction state switching member 120 in the horizontally long state, and FIG. It is a figure which shows the attitude | position (regulation attitude | position) of the regulation state switching member 120 in a vertically long state.

  That is, as described above, when the first housing 20 is rotated when the first housing 20 is switched from the horizontally long state to the vertically long state, the rotation restricting side guide pin 75 is moved from the lower end of the rotation restricting guide groove 64. It slides toward the upper end of the rotation restricting guide groove 64. Further, when the first housing 20 is rotated to switch the first housing 20 from the vertically long state to the horizontally long state, the rotation restricting side guide pin 75 is directed toward the end portion from the upper end portion of the rotation restricting guide groove 64. Move the slide.

  The restriction state switching member 120 can be changed in posture between the non-restricted posture and the restricted posture as the rotation restricting guide pin 75 slides between the lower end portion and the upper end portion of the rotation restricting guide groove 64. It is configured.

  More specifically, the restriction state switching member 120 is configured such that two switching contact portions 122 are connected in a substantially V shape via a support shaft portion 124. Further, the height adjustment restriction shaft 110 is formed in a substantially rod shape, and one end 111 thereof is coupled to the restriction state switching member 120 in a non-rotating state. More specifically, the height adjustment regulating shaft 110 is formed in a round bar shape whose middle part in the longitudinal direction has a circular cross-sectional shape, and both end portions 111 and 112 thereof have a non-circular cross-sectional shape (here, circular both side portions). Is formed in a substantially oval shape as if cut out. Then, the one end 111 of the height adjustment restriction shaft 110 is fitted into the connecting hole 124h formed in the support shaft part 124, so that the height adjustment restriction shaft 110 and the restriction state switching member 120 are in a non-rotating state. It is connected. Note that each end of the restricted state switching member 120 may be oval, semicircular, polygonal, or the like.

  Further, the height adjustment regulating shaft 110 is movable in the height direction in conjunction with the first housing 20 by the height direction movable side member 84 or the second housing side support member 60, etc., and has its own central axis. It is supported so that it can rotate freely. In this supported state, the one end 111 of the height adjustment regulating shaft 110 is disposed between the second housing side support member 60 and the first housing side support member 50. The restriction state switching member 120 is disposed between the second housing side support member 60 and the first housing side support member 50 so that the rotation posture can be changed between the non-regulation posture and the restriction posture. .

  Here, as shown in FIG. 6, the switching contact portion 122 on one side is disposed in the rotation restricting guide groove 64, and the switching contact portion 122 on the other side is disposed on the lower end side along the rotation restricting guide groove 64. The attitude of the restricted state switching member 120 toward the position is the non-regulated attitude. Further, as shown in FIG. 7, the switching contact portion 122 on the other side is excreted in the rotation restricting guide groove 64 and the switching contact portion 122 on the one side is directed along the rotation restricting guide groove 64 toward the upper end side. Further, the posture of the restricted state switching member 120 is the restricted posture.

  As shown in FIG. 6, in the horizontally long state, the rotation restriction side guide pin 75 is positioned at the lower end of the rotation restriction guide groove 64, and the restriction state switching member 120 is in the non-restricted posture. In this state, when switching from the horizontally long state to the vertically long state, the rotation restricting guide pin 75 moves along the rotation restricting guide groove 64 from its lower end to its upper end. At this time, the rotation restricting guide pin 75 contacts the switching contact portion 122 on one side of the restricting state switching member 120. Accordingly, the restriction state switching member 120 changes its rotational posture so that the switching contact portion 122 on the one side of the restriction state switching member 120 is pushed to the upper end side of the rotation restriction guide groove 64. In the vertically long state, as shown in FIG. 7, the restricted state switching member 120 changes its posture to the restricted posture. Further, when switching from the vertically long state to the horizontally long state, the restricted state switching member 120 changes its posture from the restricted posture to the non-restricted posture by the reverse operation.

  8-10 is explanatory drawing which shows the height adjustment control shaft 110 and the height adjustment control member 130. FIG.

  As shown in FIGS. 1 and 8 to 10, the height adjustment restricting member 130 is provided at a certain height position on the height direction fixed side member 82 side. Here, it is fixed to the back support 34 on the second housing 30 side.

  The height adjustment restricting member 130 is formed as a plate-like member having a vertical dimension larger than the moving range in the height direction of the first housing 20. The height adjustment regulating member 130 is formed with a height adjustment regulating groove 132 along the vertical direction. The height adjustment regulating groove 132 is formed in a groove shape in which the non-regulating portion 133 and the regulating portion 134 are continuous along the height direction. More specifically, the height adjustment restricting groove 132 is formed in a substantially keyhole shape above a substantially round hole-shaped non-restricting portion 133, in which a slit groove-like restricting portion 134 having a predetermined width continues substantially linearly. ing. The non-regulating portion 133 is formed in a round hole shape having a sufficiently large diameter so that the other end portion 112 portion having a non-circular cross-sectional shape of the height adjustment regulating shaft 110 can be rotatably disposed. The restricting portion 134 is formed in a slit groove shape having substantially the same width as the minimum width of the other end 112 of the height adjustment restricting shaft 110 (here, the dimension in the minor axis direction of the oval cross-sectional shape). . The other end portion 112 of the height adjustment restricting shaft 110 can be disposed in the restricting portion 134 only in a predetermined posture in which the major axis direction is disposed along the load in the extending direction of the restricting portion 134. It can be moved up and down along the portion 134.

  Thereby, the height adjustment restriction shaft 110 is in a height adjustment non-restriction range corresponding to the non-restriction portion 133 (here, the lowest position in the height direction support range by the height adjustment mechanism 80). The other end 112 can be disposed in the non-restricted portion 133 in a state of being rotatable around its own central axis. Further, the height adjustment restriction shaft 110 is in a height adjustment restriction range corresponding to the restriction portion 134 (here, a range above the lowest position of the height direction support range by the height adjustment mechanism 80). Then, the other end 112 of the height adjustment restricting shaft 110 can be disposed in the restricting portion 134 only in a predetermined posture (a posture in which the long axis direction is aligned with the extending direction of the restricting portion 134). It is said that.

  The height adjustment restriction groove 132 may be a groove shape penetrating the front and back of the height adjustment restriction member 130 or may be a bottomed groove shape, or a groove shape that opens to the first housing 20 side. I just need it.

  An operation of regulating the position in the height direction by the rotary display device 10 configured as described above will be described.

  First, in the horizontally long state, the restricted state switching member 120 is in a non-restricted posture (see FIG. 6), and accordingly, the other end portion 112 of the height adjustment restricting shaft 110 has its major axis direction in the height direction. It is the posture arranged along. In this state, as shown in FIGS. 8 and 9, the other end portion 112 of the adjustment regulating shaft 110 can move in the vertical direction in the non-regulating portion 133 and the regulating portion 134 of the height adjustment regulating groove 132. is there. For this reason, in the horizontally long state, the first housing 20 can be adjusted and moved along the height direction under the support of the height adjusting mechanism 80.

  When the first housing 20 is switched and rotated from the horizontally long state to the vertically long state, the operation is as follows.

  First, when the first housing 20 is supported at the lowest position by the height adjustment mechanism 80, the other end portion 112 of the height adjustment restriction shaft 110 has a height adjustment restriction groove 132 as shown in FIG. Is disposed in the non-restricted portion 133 at the lowermost end. When the first housing 20 is rotated in this state, the rotation restricting side guide pin 75 slides along the rotation restricting guide groove 64 from the lower end to the upper end. By contacting the rotation restricting guide pin 75, the restricting state switching member 120 changes its posture from the non-restricting posture to the restricting posture, and the other end 112 of the height adjustment restricting shaft 110 has its long axis direction left and right. The posture is arranged along the direction (see FIG. 10). In this state, the other end 112 of the height adjustment restriction shaft 110 cannot be moved from the lowermost non-restriction part 133 of the height adjustment restriction groove 132 into the restriction part 134 above it. Therefore, the first housing 20 cannot be moved upward from the lowest position in a state where the first housing 20 is changed to the vertically long posture. That is, in a state where the first housing 20 is changed to the vertically long posture, the stable state in which the center of gravity of the first housing 20 is lowered as much as possible is maintained.

  On the other hand, when the first housing 20 is supported at a position above the lowest position by the height adjustment mechanism 80, the other end portion 112 of the height adjustment restriction shaft 110 is restricted by the height adjustment restriction groove 132. It is disposed in the portion 134 and cannot rotate around its own central axis. Since the rotation of the height adjustment regulating shaft 110 is regulated, the regulated state switching member 120 is also regulated so as to be maintained in the regulated posture. For this reason, even if the first housing 20 is to be rotated, the rotation restricting side guide pin 75 comes into contact with the switching contact portion 122 of the restricting state switching member 120 while being slid along the rotation restricting guide groove 64. Then, the movement from there is restricted. Thereby, in the state where the first housing 20 is above the lowest position, the posture change of the first housing 20 from the horizontally long state to the vertically long state is restricted.

  The switching operation from the vertically long state to the horizontally long state is as follows.

  That is, in the vertically long state, as described above, the first housing 20 can be positioned only at the lowest position. In this state, the other end portion 112 of the height adjustment restricting shaft 110 is disposed in the lowermost non-restricting portion 133 of the height adjustment restricting groove 132 as shown in FIG. When the first housing 20 is rotated in this state, the rotation restricting guide pin 75 slides along the rotation restricting guide groove 64 from its upper end portion toward its lower end portion. By contacting the rotation restricting guide pin 75, the restricting state switching member 120 changes its posture from the restricting posture to the non-restricting posture, and the other end portion 112 of the height adjustment restricting shaft 110 moves its longitudinal axis up and down. The posture is arranged along the direction (see FIG. 8). And when the 1st housing | casing 20 will be in a horizontally long state, as mentioned above, the 1st housing | casing 20 will be in the state supported by the height adjustment mechanism 80 so that height adjustment is possible.

  According to the rotary display device 10 configured as described above, the height adjustment regulating shaft 110 is rotated in a predetermined rotational posture (here, the major axis direction of the other end 112 is increased as the first housing 20 rotates). In the posture disposed in the vertical direction (horizontal state), the height adjustment restriction shaft 110 is movable along the non-restriction portion 133 and the restriction portion 134 of the height adjustment restriction groove 132. For this reason, in the said state, the height adjustment regulation shaft 110 can be moved to a height direction, and the height adjustment of the rotation support mechanism 40 and the 1st housing | casing 20 can be performed. On the other hand, when the height adjustment restriction shaft 110 is not in the predetermined rotation posture as the first housing 20 rotates (here, a posture in which the major axis direction of the other end portion 112 is disposed along the left-right direction, In the vertically long state), the other end 112 of the height adjustment restriction shaft 110 can be disposed only in the restriction portion 134 of the height adjustment restriction groove 132 and cannot be disposed in the non-restriction portion 133. Thereby, the position (or moving range) of the height adjustment restriction shaft 110 in the height direction is restricted. Thereby, the position of the height direction of the 1st housing | casing 20 can be controlled according to the rotation state of the 1st housing | casing 20 which has the display part 22. FIG. Here, the height adjustment can be performed in a state where the first housing 20 is in the horizontally long state, and the first housing 20 can be switched to the vertically long state only in a state where the first housing 20 is disposed at the lowest position. When the first housing 20 is in the vertically long state, the height cannot be adjusted from the lowest position. Thereby, the position of the height direction of the display part 22 can be regulated according to the rotation state of the 1st housing | casing 20 which has the display part 22. FIG. Further, since the height adjustment restricting shaft 110 rotates around its own axis, such restriction can be realized with a compact configuration as much as possible. Further, since the restriction can be realized by the position and rotation posture of the height adjustment restriction shaft 110, a relatively simple configuration with a relatively small number of parts can be achieved, and the cost can be reduced. Furthermore, as a result of being able to achieve a compact size, the amount of raw materials can be reduced.

  In addition, as the rotation restricting guide pin 75 slides between one end and the other end of the rotation restricting guide groove 64, the height adjustment restricting shaft 110 is rotated to move the moving range in the height direction. It is possible to switch between a state of regulating the state and a state of not regulating. For this reason, the rotation posture state of the height adjustment regulating shaft 110 can be greatly different between the horizontally long state and the vertically long state (here, the mutual postures rotated by about 90 degrees), and the moving range in the height direction can be more reliably ensured. Can be regulated.

  Moreover, as the height adjustment regulating shaft 110, a shaft having a round bar shape at the middle portion in the longitudinal direction and a non-circular shape at both end portions is used, and is supported rotatably at the middle portion in the longitudinal direction and rotated at both end portions. The structure which aimed at stopping can be used. In particular, even if a relatively large rotational moment acts on the height adjustment restriction shaft 110, the restriction state switching member 120 can be connected in a non-rotating state with a relatively simple configuration.

Embodiment 2. FIG.
A rotary display device according to Embodiment 2 will be described. Note that the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted, and differences will be mainly described.

  FIG. 11 and FIG. 12 are diagrams showing the restriction state switching member 120 and its biasing member portion of the rotary display device according to the second embodiment. FIG. 11 shows the restricted state switching member 120 in the restricted posture, and FIG. 12 shows the restricted state switching member 120 in the unregulated posture.

  The height adjustment regulation mechanism according to the present embodiment includes a biasing member 210 that biases the regulation state switching member 120 to a regulation posture and a non-regulation posture.

  Here, the urging member 210 is constituted by a coil spring. One end portion of the urging member 210 is fixed to an inner corner side portion of the restriction state switching member 120 where the two switching contact portions 122 extend, and the other end portion of the urging member 210 is height-adjusted. It is fixed to the second housing side flat plate portion 61 on the opposite side of the other end portion with the restriction shaft 110 in between, and is provided in an extended state. The urging member 210 urges the restricted state switching member 120 to a restricted posture or a non-restricted posture with a state passing through the central axis of the height adjustment restricting shaft 110 as a boundary. That is, when the restricted state switching member 120 is changed from the neutral posture between the non-restricted posture (see FIG. 11) and the restricted posture (see FIG. 12) to the restricted posture side, the urging member 210 switches the restricted state. The member 120 is urged toward the regulation posture side. Further, when the restricted state switching member 120 is changed from the neutral posture to the non-regulated posture side, the biasing member 210 biases the restricted state switching member 120 to the non-regulated posture side.

  The second casing-side flat plate portion 61 is formed with a protrusion 220 that regulates the change in the posture of the restriction state switching member 120 in a state where the restriction state switching member 120 is changed to the restriction posture or the non-regulation posture. Yes. The urging force by the urging member 210 is received by the protrusion 220.

  According to the second embodiment, when the rotation restricting guide pin 75 moving along the rotation restricting guide groove 64 presses the switching contact portion 122, the restricting state switching member 120 changes its posture beyond the neutral position. Then, the regulation state switching member 120 changes the attitude more reliably to the regulation attitude or the non-regulation attitude. Accordingly, the height adjustment regulating shaft 110 can be clearly switched between a height adjustable state and a height adjustment restricted state, and the height adjustment allowable state and the restricted state can be more reliably switched. it can.

Embodiment 3 FIG.
A rotary display device according to Embodiment 3 will be described. Note that the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted, and differences will be mainly described.

  13 is an explanatory view showing a rotary display device according to Embodiment 3, FIG. 14 is a perspective view showing a height adjustment regulating shaft 310, and FIG. 15 is a bending structure portion 314 of the height adjustment regulating shaft 310. It is a figure which shows a part.

  In the present embodiment, a posture change mechanism unit 320 (also referred to as a tilt structure) that supports the first housing 20 so that the posture can be changed is provided between the rotation support mechanism 40 and the height adjustment mechanism 80. Here, the posture change mechanism unit 320 has a posture change axis in at least the left-right direction and the vertical direction. As a result, the first housing 20 is configured to be able to change its posture in the front diagonally up and down direction, and can be changed in posture to the front diagonally left and right direction. Regarding the structure of the support mechanism itself that can change the posture in at least two axial directions, various mechanisms used in general liquid crystal display devices, such as a shaft support structure using a concavo-convex structure, a spherical body, and a spherical body are used. Since it is realizable with various structures using the dent etc. to hold | maintain, detailed description is abbreviate | omitted here.

  The height adjustment restriction shaft 310 is a member corresponding to the height adjustment restriction shaft 110. Here, the height adjustment restriction shaft 310 includes the shaft portion 310A on the first housing 20 side and the second housing 30 side. The shaft portions 310 </ b> B and the shaft portions 310 </ b> A and 310 </ b> B are connected via a bending structure portion 314.

  The bending structure portion 314 can be bent at least in the vertical direction and the horizontal direction, and can be bent around the posture changing axis L1 along the vertical direction and the posture changing axis L2 along the horizontal direction by the posture changing mechanism 320. It is preferable.

  Here, an example is shown in which an elastic relay member that can be bent by elastic deformation, more specifically, a coil spring is used as the bending structure portion 314. By using a coil spring, it can be set as a comparatively cheap structure.

  According to the third embodiment, the rotation of the one end portion 311 is transmitted to the other end portion 312 even when the posture of the display portion 22 and the first housing 20 is changed and the height adjustment restricting shaft 310 is bent. Rotate. Then, the other end portion 312 of the height adjustment restriction shaft 310 can be kept in the height adjustment restriction groove 132 so as not to be disengaged from the height adjustment restriction groove 132. For this reason, the effect of the said Embodiment 1 can be implement | achieved, enabling the attitude | position change of the display part 22 and a 1st housing | casing.

  Further, in the third embodiment, the other end portion 312 of the height adjustment regulating shaft 310 is formed so that the cross-sectional shape gradually decreases toward the distal end side. As a result, even if the vertical center axes of the bending structure portion 314 in the vertical direction and the horizontal direction are slightly deviated from the posture change axes L1 and L2 by the posture change mechanism portion 320, the other end portion 312 has the height adjustment restriction groove 132. It is possible to keep the state in which the rotation is restricted and the movement is restricted.

  Below, the modification of the said Embodiment 3 is demonstrated. Note that the same components as those in the first embodiment or the third embodiment are denoted by the same reference numerals and the description thereof will be omitted, and differences will be mainly described.

  FIG. 16 is an exploded perspective view showing the height adjustment regulating shaft 410 according to the first modification. In the height adjustment regulating shaft 410, the shaft portions 310 </ b> A and 310 </ b> B are connected via the bending structure portion 412.

  The bending structure portion 412 includes a pair of shaft connecting pieces 411A provided on the shaft portion 310A, a pair of shaft connecting pieces 411B provided on the shaft portion 310B, and a relay rotating shaft portion 414. The relay rotation shaft portion 414 is formed in a columnar shape that can be disposed between the pair of shaft coupling pieces 411A and between the pair of shaft coupling pieces 411B.

  Then, the relay rotation shaft portion 414 and the pair of shaft connection pieces 411A can be freely rotated by the pair of shaft connection pieces 411A so as to sandwich the relay rotation shaft portion 414 from above and below in the axial direction via the fixing pins 416A and the projections 414a. Link. Further, the relay rotation shaft portion 414 and the pair of shaft connection pieces 411A are rotatably connected via the fixing pins 416B so that the relay rotation shaft portion 414 is sandwiched from both sides by the pair of shaft connection pieces 411B.

  Thereby, similarly to the above, a configuration in which the height adjustment restriction shaft 410 can be bent in at least two directions is realized.

  FIG. 17 is a cross-sectional view showing a height adjustment regulating shaft 510 according to a second modification, FIGS. 18 and 19 are cross-sectional views showing a principal part of the bending structure 512, and FIG. 20 shows an end of the shaft portion 310B. FIG. 21 is a perspective view showing an end portion of the shaft portion 310A.

  In the height adjustment regulating shaft 510, the shaft portions 310 </ b> A and 310 </ b> B are connected via a bending structure portion 512.

  The bending structure portion 512 has an uneven joint structure having a convex spherical portion 514 formed at the end of the shaft portion 310A and a concave spherical portion 516 formed at the end of the shaft portion 310B.

  The convex spherical portion 514 is formed in a substantially hemispherical shape, and the concave spherical portion 516 is formed in a substantially hemispherical concave shape into which the convex spherical portion 514 can be fitted.

  Further, the concave spherical portion 516 has a protrusion 516a. Here, the protrusion 516a is formed in a protrusion having a constant width extending along the left-right direction.

  Further, the convex spherical portion 514 is formed with a concave strip portion 514a into which the protruding strip portion 516a can be fitted with play. Here, the depth dimension of the recess 514a is set to be larger than the protrusion dimension of the protrusion 516a. Then, with the protrusion 516a fitted in the recess 514a, the convex spherical portion 514 and the concave spherical portion 516 can be bent in a plane including the respective extending directions (here, in the left-right direction). ing. Moreover, the width dimension of the concave strip part 514a is substantially the same as the width dimension of the protruding strip part 516a on the back side thereof, and is gradually increased toward the opening side. Accordingly, the convex spherical portion 514 and the concave spherical portion 516 can be bent so that the neck sways on both sides in the thickness direction of the protruding portion 516a in a state where the protruding portion 516a is fitted in the recessed portion 514a. ing.

  Then, the protrusions 516a are fitted into the concave ridges 514a, and the convex spherical portions 514 are fitted into the concave spherical portions 516 so that the shaft portions 310A and 310B are arranged to face each other, thereby adjusting the height adjustment. It is possible to realize a configuration in which the shaft 510 can be bent in at least two directions and the rotation of one end can be transmitted to the other end.

  The extending direction of the protrusion 516a and the recess 514a may be the vertical direction.

Modified example.
Note that the positional relationship between the non-regulating portion 133 and the regulating portion 134 of the height adjustment regulating groove 132 described above is an example, and is not necessarily limited to the above example. For example, a regulation portion that is normally narrow may be formed at both ends in the height direction (upward and downward) of the non-regulation portion that is normally wide. In short, it is sufficient that the restriction portion as described above is formed at a predetermined height position or range that is subject to rotation restriction. The shape of the restriction portion 134 is not limited to the above example, and may be any shape that can form a space in which the other end 112 of the height adjustment restriction shaft 110 can be rotated.

  Further, the height adjustment regulating shaft is not limited to the above example, and can be moved in the height direction in accordance with the height adjustment of the first casing, and the first casing can be rotated (particularly between the horizontally long state and the vertically long state). It suffices if it can be rotated along with (switching rotation). For example, if the first housing 20 is configured to rotate around a predetermined rotation axis, the shaft portion connected to the rotation axis may be used as the height adjustment restriction shaft.

  In each of the above embodiments, the horizontally long state and the vertically long state may be switched by rotating in the opposite direction. In this case, the configuration may be symmetrical with respect to the vertical line.

  Moreover, the 1st housing | casing side support member 50 and the 1st housing | casing 20 and the 2nd housing | casing side support member 60 and the 2nd housing | casing 30 may be comprised as the same member.

  In this embodiment, a stand-type display device has been described as an example. However, the present invention is not limited to this example, and can be applied to various display devices that rotatably support a display unit.

  Moreover, each structure demonstrated by said each embodiment and each modification can be suitably combined unless it mutually contradicts.
