DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a seat armrest provided with a television receiver according to the present invention will be described below with reference to the drawings.

Figure 1 is a perspective view showing the television receiver taken out from the center armrest, and Figure 2 is a side sectional view of the same main part. The armrest 2 to be attached is a recess formed at the lower part of the cocktail tray 3 formed at the upper front end 1a of the armrest 1. In this embodiment, two recesses 2, 2 are formed in one armrest 1 in order to accommodate two television receivers.
This concave portion 2 accommodates a television receiver 5 having a somewhat large television display portion 4 of approximately 5 to 8 inches formed in the shape of a liquid crystal plate.

This television receiver 5 has a structure in which two arms 6a, 6a bent into a substantially L-shape are supported by a so-called double link arm 6 which is biased and parallel to each other at a predetermined interval. At the front upper end 2a position of the part 2, the entire double link arm 6 is rotatable within the front upper end 2a of the recessed part 2, and its upper ends 6b, 6b can be freely moved above the armrest 1. The rear end portions 6c, 6c are pivoted in the recessed portion 2 using rotation shafts 7, 7 so that the rear end portions 6c, 6c can be moved in and out. Moreover, a wiring cable (not shown) to the television receiver 5 side can be installed inside the double link arm 6. Reference numeral 8 designates a pocket which is provided on the side of the armrest 1 and is configured to be tiltable and is used to store small items such as glasses and cigarettes.

In this invention, double link arm 6
prevents free rotation of the television receiver 5 in the support posture by biasing the support portion of the arms 6a, 6a relative to the television receiver 5, which is a supported body, and prevents the television receiver 5 from freely rotating in the support posture, The structure is such that the television receiver 5 can always be supported horizontally regardless of the rotation angle.

Also, the front end 6 of the double link arm 6
b, 6b, a hinge mechanism 9 for horizontally rotating the television receiver 5 is constructed. This hinge mechanism 9 horizontally rotates the television receiver 5 supported on the upper end of the double link arm 6, and adjusts the orientation of the display section 4 of the television receiver 5 with respect to the line of sight of the seated person. It is something.

Figures 3a, b and 4 show the operation and structure of the spring cylinder. That is,
10 is the shaft attachment 7,7 of the double link arm 6
It is a spring cylinder attached to at least one arm 6a near the section. This spring cylinder 10 has a rod 10c wrapped around a coil spring 10b inside a cylinder 10a, and is always biased to project outward within a predetermined range. One side is attached to the arm 6a side, and the other side is attached to an appropriate position in the recessed part 2 to form a double link arm 6.
When the double link arm 6 is stored and used, it acts to push the double link arm 6 upward. That is, in response to the rotation of the double link arm 6, the spring cylinder 10 aligns the dead point A, that is, the mounting position in the recess 2, with the rotation axis 7 of the double link arm 6. When the double link arm 6 is pressed from below (in the direction of arrow B), the television receiver 6 is supported above the front part of the armrest 1.

5 and 6 show the structure of the height adjustment mechanism, and reference numeral 11 denotes a stopper attached to the vicinity of the pivot 7 of the double link arm 6 via guides 12, 12. This stopper 11 is
It is formed at the tip of the worm gear 13, and its lower end comes into contact with the upper end of the double link arm 6 to restrict upward rotation of the double link arm 6. That is, armrest 1
The worm gear 13 of this stopper 11 is engaged with the gear 15 formed at the tip of the height adjustment handle 14 disposed on the side, and the double link arm 6 is rotated by rotating the height adjustment handle 14. The vertical position can be adjusted.

When viewing the television receiver 5 configured as described above, the television receiver 5 housed in the recess 2 of the armrest 1 is attached to the pivot 7 of the rear end 6c of the double link arm 6. Center the part, lift it upwards, and rotate it another 180 degrees.
In this state, since the spring cylinder 10 that urges the double link arm 6 upward is beyond the dead point A, the downward rotation of the double link arm 6 can be prevented. Next, the television receiver 5 is rotated at an arbitrary horizontal angle in the line of sight direction of the seated person using the shaft attachment 9 of the tip 6b of the double link arm 6, and the television display section 4 is rotated to the seated person's line of sight. They can be made to face each other in different directions.

On the other hand, when the television receiver 4 is housed in the recess 2, the orientation of the television receiver 5 is returned to the parallel state with respect to the recess 2, and the double link arm 6
, centering on the shaft attachment 7 part of the rear end 6c,
At the same time, the television receiver 5 is rotated 180 degrees relative to the tip 6b of the double link arm 6, and the entire television receiver 5 and double link arm 6 are accommodated in the recess 2. . At this time,
Since the spring cylinder 10 acts to push up the double link arm 6 beyond the dead point A, the double link arm 6
can prevent downward rotation.

7 to 10 show a second embodiment in which the television receiver is taken out by hand operation of a handle or lever, and 16 is a passive member fixed to the rotation shaft 7 of the double link arm 6. It's a gear. This passive gear 16 is a drive shaft 19 of a handle 17 or lever 18 configured on the armrest 1 side.
The double link arm 6 is meshed with a drive gear 20 fixed to the tip thereof, and the double link arm 6 can be easily rotated by rotating the handle 17 or the lever 18, thereby allowing the television receiver 5 to be moved in and out of the recessed portion 2. It is possible.

In addition, on the side of the seat of the armrest 1 configured as described above, a switch, volume,
An operation panel section (not shown) on which a channel, an earphone jack, etc. are arranged may also be provided. With this configuration, the television receiver 5
Since only the television display section 4 needs to be configured, a larger screen configuration is possible. Further, this operation panel section can be combined with a reading light switch for reading that is installed in general aircraft seats, a call light switch for calling a stewardess, etc., and the like.

In this embodiment, a structure in which a television receiver is provided in the center armrest of the seat has been explained.
It is also possible to configure a television receiver on another side armrest or the like.

[Effect of idea]

Since the seat armrest equipped with the television receiver according to the present invention is configured as described above, it does not interfere with the use of various existing equipment such as cocktail trays, tables, and ashtrays, and can be used as a large television display. The television receiver can be set in the optimal line of sight direction of the seated person and viewed.

Also, since it has a double link arm and a spring cylinder, it is easy to move the TV receiver in and out of the recessed part, and even if the TV receiver is kept in any position, the TV display part is always on. The television receiver can be supported in a horizontal position, and the height position of the television receiver can be easily adjusted by operating the height adjustment handle.

Furthermore, if a gear mechanism is used for the rotating shaft of the double link arm, the TV receiver can be easily moved in and out using a handle, lever, etc. The practical effects of this are extremely large.
