Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a television receiver that can be stored in the front lower part of the armrest of various seats in aircraft or vehicles, and particularly relates to as well as
This relates to a mechanism that holds the VTR's picture output wiring code.

[Conventional technology]

Conventionally, a recess for storing a television receiver is formed in the front part of the armrest of various seats of aircraft or vehicles, and a hinge mechanism with a support mechanism fixed to the upper front end of the recess is attached to the support mechanism. It has been proposed that the television receiver is pivoted so as to be able to move in and out of the recess, and that a television receiver is attached to the support mechanism so as to be rotatable in the front and back and left and right directions.

[The problem that the idea attempts to solve]

However, when the television receiver is configured to be stored in the recess of the armrest, the wiring cord for the power supply of the television receiver and the output of the VTR must be placed in the recess, and the hinge mechanism cannot be rotated. As a result, the wiring cord is pulled or pressed, bent, and in the worst case, cut by the equipment.

Furthermore, in order to allow the wiring cord to freely expand and contract in response to the rotation of the hinge mechanism, it is conceivable to wind the wiring cord in a spiral shape so as to extend it along the outer periphery of the support mechanism. However, when the television receiver is put in and taken out, the wiring cord becomes entangled with the support mechanism or the hinge mechanism, making it impossible to take out the television receiver easily.

The present invention was devised in view of the above-mentioned problems, and by reducing fluctuations in the wiring cord due to the rotation of the television receiver relative to the armrest, it increases its durability and eliminates the above-mentioned causes of failure that occur in the wiring cord. It is an object of the present invention to provide a wiring holding mechanism for a television receiver that can eliminate the problem.

[Means to solve the problem]

In order to achieve the above object, the wire holding mechanism for a television receiver according to the present invention forms a recess for storing the television receiver in the front part of the armrest of various seats of an aircraft or vehicle, and an upper part of the front end of the recess. A hinge mechanism having a support mechanism fixed thereon is pivotally installed so that the support mechanism can move in and out of the recess, and the television receiver is attached to the support mechanism in the front and back and left and right directions. In a rotatably mounted television receiver, the fixed end of the wiring guide, which is bent into a substantially arc shape toward the inside of the armrest recess, is rotatably mounted on the base end of the support mechanism in the direction of rotation. At the same time, a guide hole is formed at the tip of the wiring guide, and a protective tube with an opening facing the guide hole of the wiring guide is disposed in the armrest recess, and a protective tube is provided in the support mechanism section. The gist is to route the inserted television receiver wiring cord through the wiring guide and the inside of the protective tube.

Further, a protective strap made of an elastic member or an elastic member can be placed between the tip of the wiring guide and the opening of the protective tube.

[Effect]

According to the above configuration, when the television receiver is moved in and out of the recessed part of the armrest, the wiring cord inserted into the support mechanism part is guided by the curved inner surface of the wiring guide and the guide hole to the opening side of the protective tube. Slide forward and backward.

Even if the wiring cord becomes slack at the opening end of the protective tube, the protective strap can reliably receive the wiring cord and guide it toward the protective tube.

This is a recess formed in the lower part of the cocktail tray 3 formed at the upper end of the front part. In this embodiment, two television receivers 4, 4 are installed at the front end of the armrest 1 so that users of both seats can use them separately.
The recesses 2, 2 corresponding to the respective television receivers 4, 4 are formed in parallel. This recess 2 holds a somewhat large TV display part 5 formed in the shape of a liquid crystal plate, which is rotatably supported forward of the armrest 1 via a hinge mechanism 7 to which a supporting mechanism part 6 (described later) is fixed. The TV receiver 4 is housed therein. The recess 2
The television receiver 4, which is housed in the
It is equipped with an operation section such as a volume control.

2 to 5 show a wire holding mechanism according to the present invention.

The support mechanism section 6 horizontally rotates the television receiver 4 mounted on the upper part of the support mechanism section 6, and adjusts the orientation of the television display section 5 of the television receiver 4 with respect to the line of sight of the user. A ball shaft 6b, which is vertically disposed from the lower surface of a television holder 8 formed at the lower edge of the television receiver 4, is rotatably held by a ball bearing 6a formed on the 7 side. This TV holder 8 has a structure in which a groove is formed to be fitted from the side of the bottom of the TV receiver 4, and it can be attached and detached as appropriate.If the TV receiver 4 breaks down, the TV holder 8 can be easily removed by removing screws, etc. The receiver 4 can be configured to be replaceable. Then,
The television receiver 4 is rotatably supported within a range of approximately 90 degrees around a spherical shaft 6b, and can be held at a storage position and a viewing position.

Note that the ball bearing 6a and the ball shaft 6b may be installed upside down. Furthermore, a stopper is formed protruding from the inner periphery of the ball bearing 6a so as to reliably restrict the rotation angle to approximately 90 degrees around the shaft, and a stopper that engages with the stopper is also provided around the ball shaft 6b. It is also possible to form a protrusion.

The hinge mechanism 7 consists of a hinge bearing part (not shown) and a rotation shaft 7a, and is attached to the television receiver 4 at the upper front end of the recess 2 of the armrest 1.
The whole can freely move in and out of the opening of the recess 2, and holds the television receiver 4 fixed at a predetermined position. Reference numeral 9 denotes an insertion hole drilled in the support mechanism section 6 for the power source of the television receiver 4 and the wiring cord 10 for outputting images of the VTR.

The wiring cord 10 has a connector 11a attached to the tip thereof pulled out through the insertion hole 9 of the support mechanism section 6 on the armrest 1 side, and connects the connector 11a to the television receiver 4.
It is continuous with the female connector 11b which is recessed in the lower surface. Note that it is also possible to connect the wiring cord 10 by forming a direct contact point between the television holder 8 and the sliding contact surface on which the television receiver 4 is attached.

12 is a wiring guide formed in a substantially arc shape. A guide hole 13 for the wiring cord 10 is formed in the distal end 12a of the wiring guide 12, and the fixed end 12b of the wiring guide 12 is provided at the lower front side of the base end 6a of the support mechanism section 6. The guide 12 is rotatably pivoted with its curved inner surface facing the hinge mechanism 7 side. Further, as shown in FIG. 2, an opening 1 is provided in the recess 2 of the armrest 1.
4a faces the guide hole 13 side of the wiring guide 12, and a protective tube 14 is provided which is bent toward the lower surface of the armrest 1 in a substantially hook shape. The wiring cord 10 is pulled out from the other end of the protective tube 14 to the outside of the armrest 1, and is connected to the relay connector 1.

Thus, as shown in FIG. 6a, the support mechanism section 6
When the television receiver 4 is stored, the wiring cord 10 inserted into the insertion hole 9 is connected to the support mechanism 6 in conjunction with the storing operation of the television receiver 4, as shown in FIG. 6b. When the armrest 1 rotates forward and downward about the hinge mechanism 7, it is guided by the curved inner surface of the wiring guide 12 and the guide hole 13, and is pushed back toward the opening 14a of the protection tube 14. That is, the guide hole 13 of the wiring guide 12 is always aligned with the protective tube 14 in any state in which the support mechanism part 6 is upright, in the middle of being stored in the recess 2, or in any state in which it is stored in the recess 2. Opening 1
It will face 4a side. Therefore, the wiring cord 10 inserted through the guide hole 13 can smoothly slide forward and backward within the wiring guide 12 and the protective tube 14 in response to the rotation of the support mechanism section 6. It does not interfere with the movement of the image receiver 4 in and out, and does not protrude to the support mechanism section 6 or hinge mechanism 7 side and get tangled.

Reference numeral 16 denotes a protective strap made of a bendable or stretchable soft material and stretched between the tip 12a of the wiring guide 12 and the opening 14a of the protective tube 14. In this embodiment, the protective strap 16 is fixed on the wiring guide 12 side, and the magic tape 17 is fixed on the opening 14a side of the protective tube 14.
It is configured to be detachable at will. Therefore, when the television receiver 4 is stored, the protective strap 16 can reliably guide the wiring cord 10 toward the protective tube 14 that holds the wiring cord 10. 14 openings 14a can prevent it from getting caught.

In this embodiment, Teflon material is used for the protective tube 14 and the protective strap 16 in order to make the wiring cord 10 slide more smoothly, but any Teflon material can be used as long as it has the above effect. In addition, without limitation, the protective tube 1
Of course, the shape of 3 can also be formed into, for example, an arc shape other than the substantially hook shape.

[Effect of idea]

The wiring holding mechanism of the television receiver according to the present invention is as follows:
With the above configuration, the wiring cord is inserted into the support mechanism section and also through the protective tube, so the wiring cord does not interfere with the movement of the television receiver in and out and its rotation, and the support mechanism section Also, accidents such as getting entangled with the hinge mechanism and being cut off are also prevented.

Furthermore, since the passenger's hands and fingers do not touch the wiring cord directly, it is highly safe, and the design is also excellent in appearance.The practical effects of this invention after implementation are extremely large.
