Next, Embodiment 1 of the present invention will be described with reference to the drawings.
1 is a front view of the display device of the first embodiment, FIG. 2 is a side view of the display device of the first embodiment, FIG. 3 is a rear view of the display device of the first embodiment, FIG. Is an explanatory view showing the configuration of the coupling mechanism, and FIG. 6 is an operation explanatory view of the coupling mechanism.

As shown in FIGS. 1 to 3, the display device 10 includes a display member 12 and a placement member 14 placed on the placement surface 2, and the display member 12 and the placement member 14 are connected to each other. 16 are connected.
The display member 12 has a cover 1201 that constitutes an exterior. The cover 1201 is formed in a substantially rectangular plate shape having a length extending in the horizontal direction and a height extending in the vertical direction. The front surface 1204 has a back surface 1206 located opposite to the front surface 1204.
As shown in FIG. 4, the mounting member 14 extends in a direction perpendicular to the first arm 1402 from both ends of the first arm 1402 formed in a straight line and the first arm 1402 on the same plane. And a pair of second arms 1404 located on the left side.
Rotating shafts 1406 protrude from the respective distal end portions of the second arms 1402 outward in a direction parallel to the extending direction of the first arm 1402.
The mounting member 14 is rotatably supported by bearings (not shown) provided at two positions spaced apart in the lateral direction on the lower surface of the display member 12 on the back surface 1206 side of the mounting member 14. Thus, the display member 12 is rotated about the rotation axis 1406 in a state where the mounting member 14 is mounted on the mounting surface 2 and the display member 12 is raised on the mounting surface 2, whereby the display surface 1202 is rotated. It is comprised so that direction may be adjusted.

As shown in FIG. 5, the coupling mechanism 16 includes a fixed gear 1408, a gear damper 18, and a switching means 20 in addition to the two rotating shafts 1406.
The fixed gear 1408 is formed on each of the second arms 1402 so as to extend in a semicircular shape coaxially with the rotation shaft 1406. In this embodiment, the fixed gear 1408 is formed to extend in a range of approximately 180 degrees.
As shown in FIG. 3, the gear dampers 18 are respectively provided at two positions spaced apart in the lateral direction at the lower part on the back surface 1206 side of the display member 12.
As shown in FIG. 5, each gear damper 18 includes an annular gear portion 1802 that meshes with the fixed gear 1408, and a support that is provided on the inner periphery of the gear portion 1802 and rotatably supports the gear portion 1802. The support shaft portion 1804 is fixed to the display member 12 side.
For example, a viscous material (oil) having a high viscosity is enclosed between the inner periphery of the gear portion 1802 and the outer periphery of the support shaft portion 1804 facing the inner periphery, or a member having a large friction coefficient is interposed. When a rotational force is applied to the gear portion 1802, in other words, when the gear portion 1802 rotates on the support shaft portion 1804, the gear portion 1802 generates a predetermined resistance force (torque) in the rotational direction. It is configured to be rotated. As such a gear damper 18, for example, a commercially available product such as an oil damper manufactured by Nifco Corporation is used.
The resistance force of the gear damper 18 is set so that the display member 12 does not rotate suddenly due to the weight of the display member 12.

As shown in FIG. 6, the switching means 20 switches between allowing and preventing rotation of the gear portion 1604 of the gear damper 1602 and is provided at a position of the display member 12 close to at least one of the two gear dampers 18. It has been.
The switching means 20 includes a case 2001 provided at a location close to the gear damper 18, a gear member 2002, a biasing member 2004, and an operation member 2006.
The gear member 2002 has a stationary gear portion 2002A that can mesh with the gear portion 1802, and the stationary gear portion 2002A can be moved in a direction approaching and separating from the gear portion 1802 and cannot rotate. It is installed.
The urging member 2004 is provided inside the case 2001 and arranged to urge the gear member 2002 in a direction in which the stationary gear portion 2002A meshes with the gear portion 1802.
The operation member 2006 is formed in a shaft shape, the tip of the operation member 2006 faces the gear member 2002 inside the case 2001, and the other end protrudes outward from the case 2001, and the tip further passes through an opening provided in the back surface 1206 of the cover 1201. The spring member 2008 is biased so as to face the back of the cover 1201.
As shown in FIG. 6A, in a state where the operation member 2006 is not pressed, the gear member 2002 is urged by the urging member 2004, and the stationary gear portion 2002A is engaged with the gear portion 1802 of the gear damper 18, so that the gear The rotation of the part 1802 is prevented.
On the other hand, as shown in FIG. 6B, when the operation member 2006 is pressed against the biasing force of the spring member 2008 and the biasing member 2004, the stationary gear portion 2002A is the gear portion of the gear damper 18. The gear part 1802 is allowed to rotate away from the 1802.

Next, the function and effect of the display device 10 will be described.
When changing the orientation of the display surface 1202 of the display device 10, as shown in FIG. 2, the mounting member 14 is mounted on the mounting surface 2 and the display member 12 is erected on the mounting surface 2. Thus, as shown in FIG. 6 (A), the operation member 2006 is pressed and the gear unit 1802 is allowed to rotate by the switching means 20.
In this state, the display member 12 is gripped and the display member 12 is rotated to an arbitrary rotation position by applying a force to be described later in the direction around the rotation shaft 1406 against the resistance force generated by the gear damper 18. The direction of the twelve display surfaces 1202 is adjusted to a desired position.
When the rotation position of the display member 12 is fixed, if the pressure on the operation member 2006 is released, the rotation of the gear portion 1802 is blocked by the switching means 20 and the rotation of the display member 12 around the rotation axis 1406 is prohibited. The orientation of the display surface 1202 of the display member 12 is securely fixed.

The force required to rotate the display member 12 only needs to exceed the combined force of the force P1 generated by the weight of the display member 12 and the resistance force Pr generated by the gear damper 18, and will be described in detail as follows. is there.
(1) When the force applied by the weight of the display member 12 is the same as the rotation direction, the force (Pr) obtained by subtracting the rotation direction force P1 applied by the weight of the display member 12 from the resistance force Pr generated by the gear damper 18 A force exceeding -P1) may be applied to the display member 12. If Pr <P1, the display member 12 can be rotated with almost no force applied to the display member 12.
(2) When the force acting on the display member 12 due to its own weight is opposite to the rotation direction, the resistance force Pr generated by the gear damper 18 and the rotation direction force P1 acting on the display member 12 due to its own weight are added together. A force exceeding the force (Pr + P1) may be applied to the display member 12.
Therefore, in the case of (2), the display member 12 can be moved with a force that exceeds the sum of the resistance force Pr of the gear damper 18 and the force P1 by the display member 12, and in the case of (1) The display member 12 can be moved with a smaller force than the case, and in any case, the direction of the display surface 1202 of the display member 12 can be adjusted with a small force, which is advantageous in improving usability.
In addition, when the display member 12 rotates, a predetermined resistance force Pr is generated by the gear damper 18, so that the movement speed of the display member 12 is stabilized, so that the display member 12 can be moved smoothly, This is advantageous for smooth adjustment of the display member 12.
Further, the switching means 20 engages the stationary gear portion 2002A of the gear member 2002 with the gear portion 1802 of the gear damper 18 so as to prevent the gear portion 1802 from rotating. That is, it is advantageous in finely adjusting the direction of the display surface 1202.
Further, if the gear member 2002, the urging member 2004, and the operation member 2006 are assembled in advance in the case 2001, it is advantageous in simplifying the assembling work.
Further, the conventional display device using the spring hinge or the hydraulic hinge has a drawback that the space occupied by the spring hinge or the hydraulic hinge is large and the cost is high. However, in the display device 10 of this embodiment, the gear damper 18 and the switching device are switched. There is an advantage that the space occupied by the means 20 can be reduced and the cost can be relatively low.

  In this embodiment, the fixed gear 1408 is provided on the mounting member 14 and the gear damper 18 is provided on the display member 12. On the contrary, the fixed gear 1408 is provided on the display member 12 and the gear damper 18 is provided. You may provide in the mounting member 14. FIG.
