FIG. 3 is a longitudinal sectional view of FIG. 1, and FIG.
It is a cross-sectional view in the lateral direction of the drawing.

The panel case block 5 and the main case block 10 are arranged so as to overlap each other in plan view.

The panel case block 5 includes a cover glass 11, a panel front case 12, a panel unit 13 including a display body, a panel back case 14, a switch panel 40 which is an operating means, a switch circuit block as necessary, a screw 15, a small fluorescent tube, If necessary, it is composed of a fluorescent tube drive circuit, a control circuit block having a synchronous control circuit, and the like.

After setting the panel unit 13 in the panel front case 12, screw
The panel unit 13 is fixed by 57 to ensure vibration resistance. Next, the rotary lever 17 of the tilt unit 16 which is a rotary member is set from the inside to the side wall of the panel front case 12 with the guide pin 18 as a guide. From the outside, fix two cup-screw type screws 19 on each of the left and right. In this way, by fixing the tilt unit 16 and the panel unit 13 to the panel front case 12 that is a box-shaped component, the deformation applied to the most delicate panel unit 13 during rotation is suppressed to a small level. Switch panel
Set 40 from the front side, fix with screws from the back, then attach the panel back case 14 and fix with screws 15.

The main case block 10 is composed of a main front case 20, a circuit block A21, a circuit block B22, a main back case 23, a high frequency connector, a power supply connector, a headphone jack and the like. The circuit block A21 and the circuit block B22 include a power supply circuit, a tuning circuit, an IF processing circuit, a video processing circuit, an audio processing circuit, a chroma / video processing circuit, a synchronization control circuit, a fluorescent tube drive circuit, and a switch circuit as necessary. It is composed of Panel case block 5 with tilt unit 16 after attaching a high frequency connector, power connector, headphone jack, etc. to the main table case 20.
Attach the pin 24 (Fig. 5) to the guide from the front side, and fix it with the cup screw from the back side using two screws on each side.

FIG. 5 is a perspective exploded view showing main parts, and shows the appearance of the assembly portion well.

The switch panel 40 is a mode display section 41 that displays a mode with LEDs, a mode switch 42 that selects a mode from multiple videos, UHF, VHF, a channel switch 43 that selects a channel by auto tuning when selecting UHF, VHF, and an electronic volume. It has a volume switch 44 for adjusting the volume, a brightness switch 45 for adjusting the brightness with an electronic brightness control, and a power switch 46 for turning the power on and off.

The tilt unit 16 is a high torque rotating member that uses the friction between the coil spring 47 and the rotating shaft 48, and the rotating torque differs depending on the rotating direction. That is, the rotational torque in the A direction is large, and the B
Rotation torque in the direction is small. Therefore, in order to make the rotational torque about the same in both directions of rotation, the left and right tilt units have opposite rotational torque characteristics. Further, in this embodiment, since the switch panel 40 is on the right side,
The tilt unit, which has a large rotational torque in the direction in which the force to push the switch acts (direction A in the right tilt unit), is placed on the right side to reduce rotation and deflection when operating the switch and improve the operational feeling. . Further, in order to reduce the amount of deformation applied to the panel unit 13 during rotation, the length of the rotary lever 17 is made as long as possible, and the hole 49 for the guide pin 18 is located on the outside to have a long pitch.

The main front case 20 has a stepped portion 25 which is lowered by one step at the lower portion, and this stepped portion is further lowered by one step from the flank 26 of the panel case block 5.

In this way, the headphone jack is provided on the main case block side so that the headphone plug and cord do not get in the way when watching TV, adjusting the viewing angle, and operating the switch.

It returns to FIG. 4 and FIG. 5 and demonstrates.

Next, the circuit block A21 and the circuit block B22 are fixed with screws and the main back case 23 is fixed with screws. This completes the TV set 3.

Insert the plug of the wiring wired in the seat into the connector of the TV set 3, and then attach it to the seat.

There is a hole on the back of the seat back that is slightly smaller than the edge 28, and the TV set 3 is attached thereto.

The backrest has a back plate 30 made of plywood, a reinforcing plate 31 made of metal, and a cushion 32 fixed to the front side of the pipe 29. There is a hole in the part of the back plate 30 where the TV set 3 is inserted,
By inserting a thin and strong reinforcing plate in this part, the total thickness of the backrest can be reduced. On the back side of the pipe 29, an upper back plate 34 made of plywood having a fixing plate 33 made of metal for fixing tapping screws and a sheet material 35 are fixed. Below the TV set, a fixing plate 36 for tapping screws is firmly fixed on the back side of the back plate 30, and further on the back side, a decorative plate whose surface is covered with sheet cloth.
37 is fixed with screws. An auxiliary plate 38 is sandwiched between the back plate 30 and the upper back plate 34, and the upper back plate 34 when the TV set is fixed.
To prevent deformation.

After the TV set 3 is attached, the TV fixing screws 56, which are tapping screws as fixing means, are fixed to the fixing plates 33 and 36 by tightening the screws.

In this way, the TV set 3 is constructed by stacking the panel case block 5 and the main case block 10, and all the visible parts of the TV set are functionally necessary parts, that is, the screen, the operation part, and the edge part. As a result, the planar shape can be reduced, and the appearance and the atmosphere when watching a television can be improved.

When rotating the panel case block 5, the lower part of the panel case block 5 is grasped with a finger 39 and rotated. The part of the panel back case 14 that is gripped with fingers has an inverted rounded shape, which makes it easy to grip with fingers. Since the edge 28 of the main front case 20 is larger than the outer shape of the panel case block 5, it is possible to prevent the finger or hand from directly hitting the sheet material during the rotating operation, and the sheet material can be prevented from being soiled. Instead of the main table case
The 20 gets dirty, but it's plastic or painted plastic and is easy to clean.

As described above, by rotating only the panel case block 5, that is, by reducing the rotating portion and reducing the weight, the earthquake resistance is improved and the durability of the rotating member is also improved.

FIG. 6 is a view showing another embodiment of the main case of the present invention, in which an edge 52 of the lower step portion is extended downward and a headphone hooking portion is provided there. The ribs 50 and 51 having the projections 54 for preventing the headphones from coming off have appropriate spring properties, and the headphones 50 are located between the ribs 50 and 51.
By holding the 55 band, and setting it so that an appropriate pressure works while holding it, noise due to vibration is prevented.

Although the embodiments have been described above, the present invention is not limited to the above embodiments and can be widely used for seats such as airplanes, trains, automobiles, conference rooms, offices, etc., or TVs such as backrests and walls corresponding to the seats. Wherever there is, it can be applied.

[Advantages of the Invention] As described above, according to the present invention, by disposing the panel case block and the main case block in an overlapping manner and making the panel case block rotatable, the outer shape of the TV is small and the appearance is good, and the rotation is good. It is possible to provide a seat with a TV that is light and reliable and has high earthquake resistance.

By providing a stepped portion that is lowered by one step at the bottom of the main front case and providing an edge around the entire circumference, the panel case block can be easily rotated, and the structure of the seat can be simplified to achieve low cost. Further, there is an effect that the stain of the sheet material can be prevented, and the running cost can be kept low especially for commercial use such as a bus.
