1.3. Stand member 7
The structure of the stand member 7 is demonstrated based on FIG. The stand member 7 is a member that holds the first arm member 53 and the third arm member 57 so as to be rotatable around the fifth horizontal shaft member 739.

  The stand member 7 includes a flat plate member 71, an arm connecting member 73, an LCD position adjusting member 75, and a spring fixing member 77.

  The arm connecting member 73 includes vertical portions 733 and 735, a fourth horizontal shaft member 737, and a fifth horizontal shaft member 739. The vertical portions 733 and 735 are arranged perpendicularly to the flat plate member 71 at a predetermined interval.

  Similarly, the second arm member 55 and the fourth arm member 59 are connected to the arm connecting member 73 via the fourth horizontal shaft member 737. As a result, the second arm member 55 and the fourth arm member 59 can rotate around the fourth horizontal shaft member 737.

  As shown in FIG. 5, the first coil spring 751 has hooks f1 and f2 at both ends. The hook f1 is engaged with a hole provided in the horizontal portion 773 of the spring fixing member 77, and the first coil spring 751 is disposed at a predetermined position. The hook f <b> 2 is connected to one end of the first wire 755, and transmits the elastic force of the first coil spring 751 to the first arm member 53 via the first wire 755.

  The connection between one end of the first wire 755 and the hook f2 of the first coil spring 751 forms a loop by making one end of the first wire 755 into a loop shape and then crimping it at a predetermined position. This is achieved by hooking the hook f2 to the formed loop. In addition, the connection between the other end of the first wire 755 and the wire fixing member 537 of the first arm member 53 is to fix the other end of the first wire 755 in a loop shape and then crimp it at a predetermined position.

The first coil spring 751 and the second coil spring 753 are fixed to the flat plate member 71 via the spring fixing member 77 by engaging the hook f1 with a hole provided in the horizontal portion 773 of the spring fixing member 77. .

1.4. Friction member 8
The configuration of the friction member 8 will be described with reference to FIG. The friction member 8 has an outer friction plate 81 and an inner friction plate 83. The outer friction plate 81 and the inner friction plate 83 each have a through hole for passing through the fifth horizontal shaft member 739. One set of the outer friction plate 81 and the inner friction plate 83 penetrates the fifth horizontal shaft member 739, and the friction plate fixing portion 739T provided at the tip of the fifth horizontal shaft member 739 and the arm connecting member 73 is disposed between the vertical portion 733 and the vertical portion 733. The outer friction plate 81 is disposed on the friction plate fixing portion 739T side, and the inner friction plate 83 is disposed on the vertical portion 733 side.

  A frictional force is generated on the surface where the outer friction plate 81 and the inner friction plate 83 are in contact. With the help of this frictional force, the LCD 31 is fixed at a predetermined position.

2. Operation of Display Device 1 An outline of the operation of the display device 1 will be described with reference to FIG. In FIG. 6, the LCD 31 is not shown. Further, it is assumed that the own weight W of the LCD acts on the center point of the LCD fixing member 331.

  The first arm member 53 can rotate around the fifth horizontal shaft member 739. Further, the second arm member 55 can rotate around the fourth horizontal shaft member 737. Further, the first arm member 53 and the second arm member 55 are connected to the second horizontal shaft member 517 to the fifth horizontal shaft member 739 to form a parallel link. Although not shown in FIG. 6, the same applies to the third arm member 57 and the fourth arm member 59.

  The own weight W of the LCD acts in the direction of the arrow a1. Due to the weight W of the LCD, the tension T acts on the first wire 755 at the position of the wire fixing member 537 in the direction of the arrow a3. Therefore, the tensile force F acts on the first arm member 53 in the direction of the arrow a5 opposite to the arrow a3 at the position of the wire fixing member 537. The pulling force F has the same magnitude as the tension T, and the acting direction is a force opposite to the direction in which the tension T acts at the position of the wire fixing member 537.

  Further, the tension T acts on the first wire 755 in the direction of the arrow a7 at the connection portion between the first coil spring 751 and the hook f2. Therefore, the tensile force P acts on the first coil spring 751 in the direction of the arrow a9 in the direction opposite to the arrow a7 at the position of the hook f2. The pulling force P has the same magnitude as the tension T, and the direction in which it acts is a force that is opposite to the direction in which the tension T acts at the position of the hook f2.

  Thus, the first arm member 53 is rotated counterclockwise N about the fifth horizontal axis member 739 based on the weight W of the LCD. On the other hand, the first arm member 53 is rotated clockwise M around the fifth horizontal shaft member 739 based on the pulling force F. That is, the first wire 755 has the fifth arm M based on the rotation M of the first arm member 53 around the fifth horizontal shaft member 739 based on the elastic force of the first coil spring 751 and the own weight W of the LCD. The first coil spring 751 and the first arm member 53 are coupled so that the rotation N of the first arm member 53 centering on the horizontal shaft member 739 is opposed.

In the present embodiment, the friction member 8 has a first rotation based on the rotation M of the first arm member 53 centered on the fifth horizontal shaft member 739 based on the elastic force of the first coil spring 751 and the weight W of the LCD. Since the frictional force that corrects the imbalance with the rotation N of the first arm member 53 centering on the fifth horizontal shaft member 739 is generated, the LCD 31 can be fixed at a predetermined position.

[Other Examples]
(1) Coil spring (type)
In the above-described first embodiment, the first coil spring 751 and the second coil spring 753 are shown as the elastic members, but the elastic members are not limited to the examples as long as they generate elastic force. For example, a hydraulic spring, a pneumatic spring, a conston spring, a torsion coil spring, rubber or the like may be used.

(2) Coil spring (number)
In the first embodiment described above, the two first coil springs 751 and the second coil spring 753 are shown as the elastic members. However, the elastic member is not limited to the illustrated example as long as it is one or a plurality of elastic members. For example, the elastic member may be configured by a single coil spring. In this case, when using two wires of the first wire 755 and the second wire 757 as in the first embodiment, as shown in FIG. 7A, the two wires are connected to one end of the coil spring. That's fine.

(3) Coil spring (position)
In the first embodiment described above, the first coil spring 751 and the second coil spring 753 as elastic members are provided on the base member, but the invention is not limited to the example. For example, each coil spring may be provided on the LCD fixing member 33.

(4) Wire (form)
In the above-described first embodiment, the first wire 755 and the second wire 757 are shown as the connecting members. However, the connecting member is not limited to the illustrated example as long as the elastic member and the supporting member are connected. For example, chemical fiber, plastic, chain, natural fiber, etc. may be used.

(5) Wire (number)
In the first embodiment described above, the two first wires 755 and the second wires 757 are shown as the connecting members. However, the connecting member is not limited to the illustrated one as long as it is one or a plurality of connecting members. For example, the connecting member may be constituted by a single wire. In this case, when using two coil springs of the first coil spring 751 and the second coil spring 753 as in the first embodiment, as shown in FIG. 7B, one end of the two coil springs is connected to one end of the wire. What should I do?

(6) Wire receiver In the above-mentioned Example 1, the sleeve receivers were illustrated as the wire receivers 737U and 739U. However, the present invention is not limited to the examples as long as the positions of the wires in the fourth horizontal shaft member 737 and the fifth horizontal shaft member 739 do not shift and the wires can move smoothly. . For example, a rotation free shaft and a pulley may be used.

(7) Arm member In the above-described first embodiment, each of the first arm member 53 to the fourth arm member 59 has a U-shape. However, as long as one end of the connecting member is fixed and a part of the connecting member can be stored, the connecting member is not limited to the example. For example, each arm member may have an arch shape. In this way, by making the design of each arm member a free shape, it is possible to create a new design of the display device.

(8) Friction member 8 (configuration)
In the first embodiment, the friction member 8 is composed of the outer friction plate 81 and the inner friction plate 83. However, when the first arm member 53 to the fourth arm member 59 are about to rotate, The first arm member 53 to the fourth arm member 59 are not limited to those illustrated as long as the rotation preventing force is generated in the direction of preventing the rotation. For example, a latch, a rotary damper, or the like may be used.

(9) Friction member 8 (location)
In the first embodiment described above, the friction member 8 is disposed on the fifth horizontal shaft member 739 and generates a frictional force in a direction that prevents the rotation of the first arm member 53 to the fourth arm member 59. However, the present invention is not limited to the illustrated arrangement location as long as the rotation prevention force that prevents the rotation is generated. For example, the second horizontal shaft member 517, the third horizontal shaft member 519, and the fourth horizontal shaft member 737 may be disposed.

  Further, the arrangement location of the friction member 8 is not necessarily limited to one place, and a frictional force may be generated by arranging the friction member 8 at a plurality of places.

(10) Interference prevention sheet In the above-mentioned Example 1, the interference prevention sheet was provided for the purpose of preventing the power supply wiring or the monitor wiring from interfering with the wire. However, the interference prevention sheet need not be provided. In addition, the sheet used as the interference prevention sheet may be a sheet other than a plastic sheet as long as it prevents interference between the power supply wiring or the monitor wiring and the wire.

(11) Eccentric cam In the first embodiment, the lengths of the first wire 755 and the second wire 757 are the same so that the first coil spring 751 and the second coil spring 753 operate in the same manner. The position of the wire fixing member 537 in the first arm member 53 and the position of the wire fixing member 577 in the third arm member 57 are the same position. However, the first coil spring 751 and / or the second coil spring 753 may have different operations. For example, the sleeve-shaped wire receiver 739U in 1 in FIG. 8A embodiment may have an eccentric cam shape. Thereby, it becomes possible to operate one coil spring from a predetermined state by the design of the eccentric cam.

  Further, as shown in FIG. 8B, three wire members may be provided, and an eccentric cam may act on each of them.

Further, when a plurality of coil springs are provided, the strength values of the coil springs may be different.
