Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to vehicles such as aircrafts, buses, railway vehicles, and ships,
The present invention relates to various seats used in conference rooms, halls, and the like, and more particularly to a monitor device for seats in which a monitor for watching a video program or a television broadcast program is attached to an armrest.

[Problems to be Solved by Conventional Techniques and Inventions] Mainly for vehicles such as airplanes, buses, and railway vehicles so that passengers seated in the seats can personally watch video programs and television broadcast programs. In order to do so, development is underway to attach a small monitor using liquid crystal or the like to each seat.

The seat monitor devices developed so far include, for example, the following ones, but each has a problem.

(1) Monitor device attached to the back of the backrest Although this structure is simple, when the front backrest or one's backrest reclines, the relative positional relationship between the monitor and one's eyes and the tilt angle. Since there is a large change in the value, there is a problem that the monitor is difficult to see.

(2) A monitor device in which a support plate with a connector pivotally provided at the front end of the upper surface of the armrest is erected so that the tilt angle can be adjusted and is detachably attached to the support plate (Japanese Utility Model Publication No. 64-47458). Although the problem of (1) above is alleviated,
The tilt angle of the monitor cannot be adjusted to point to the line of sight of the passenger, which is still difficult to see. In addition, the detachable monitor may be stolen.

(3) A monitor device attached to the intermediate box between the left and right seats via an arm, a slide arm and a swing arm (Japanese Utility Model Laid-Open No. 64-54079). According to this structure, the tilt angle and swing angle of the monitor can be adjusted. Since it can be adjusted, the problem (1) or (2) is solved. However, each arm has to be largely moved when the monitor is taken out from the intermediate box or stored, which is troublesome to operate.

(4) A monitor device is provided on the front of the armrest with a monitor storage hole and is attached to the upper front end of the armrest via a universal joint (aircraft seats exhibited at the World Design Expo held in Nagoya in 1989). Although this structure also solves the above problem (1) or (2), when taking out the monitor from the storage hole in the front of the armrest, it is necessary to collapse the natural sitting posture and lean a little. Also, it is good that the tilt angle and swing angle of the taken out monitor can be arbitrarily adjusted by moving the universal joint in a complicated manner, but conversely, when the monitor is stored, the tilt angle and swing angle are in the original state. Since the way of moving the universal joint to return to is complicated (the movement is not fixed), unfamiliar passengers may worry about the operation.
Further, since the monitor is housed so as to be surrounded by the housing hole, it is necessary to consider so that heat radiation of the monitor immediately after housing, for example, in the case of a liquid crystal panel, cooling of the backlight is not hindered.

The object of the present invention is to solve the above-mentioned problems and allow the monitor to be taken out and stored without any hesitation by a simple and easy operation in a natural sitting posture, and the tilt angle and swing angle of the monitor can be adjusted. An object of the present invention is to provide a monitor device for a new seat that can be adjusted to an angle that is easy to see and that does not interfere with heat dissipation immediately after the monitor is stored.

[Means for Solving the Problems] In order to achieve the above object, a monitor device for a seat according to the present invention is provided with a recess for storing a monitor provided at a front end of a side surface of an armrest of a seat, and a front end of the recess for storing. A first rotating member rotatably mounted about a first hinge shaft extending in the vertical direction and a second rotating shaft extending in the horizontal direction with respect to the first rotating member. A second pivoting member movably attached to the second pivoting member, and a monitor pivotally attached to the second pivoting member around a third hinge shaft extending in a direction perpendicular to the second hinge shaft. The configuration was taken.

[Operation] (1) In the seat monitor device configured as described above, when the monitor is taken out and used, the following operation is performed.

The monitor housed in the housing recess at the front end of the side surface of the armrest is rotated about the first hinge shaft to be taken out from the housing recess, and the swing angle of the monitor is adjusted to an angle that is easy to see. At this time, the monitor screen is lying sideways.

Next, the monitor is rotated about the second hinge shaft to raise the screen of the monitor substantially vertically.

Next, the monitor is rotated about the third hinge shaft to adjust the tilt angle of the monitor so that it is easy to see.

As described above, since the monitor in the present invention is located at the front end of the side of the armrest that can be reached by the seated person, it can be taken out in a natural sitting posture without leaning forward.
Even an unskilled seated person can easily take out the monitor and adjust its tilt angle and swing angle simply by performing three rotation operations whose movement is simple and small as described above. And it can be done easily.

(2) When storing the monitor, operate as follows.

The monitor is rotated around the third hinge axis to return the tilt angle of the monitor to the original vertical state.

Next, the monitor is turned around the second hinge shaft to tilt the screen of the monitor sideways.

Next, the monitor is rotated around the first hinge shaft and fitted into the storage recess to be stored.

Therefore, the monitor according to the present invention can be stored in a natural sitting posture, and even if it is an unskilled seated person, the movement is simple and small as described above. It can be stored easily and easily just by performing operations. Further, since the monitor is housed in the housing recess on the side surface of the armrest and is not surrounded as in the conventional example (4), heat radiation of the monitor immediately after housing is hardly disturbed.

[Embodiment] Next, an embodiment of a seat monitor device embodying the present invention will be described in detail with reference to FIGS. 1 to 6.

In this embodiment, two small monitors 2 for left and right passengers are attached to the front ends of the left and right side surfaces of an armrest 1 provided between two seats (not shown). A liquid crystal type is generally used as the monitor 2, but another type may be used as long as it is small. Since the two monitors 2 are mounted symmetrically, only the monitor 2 for passengers on the left side (which appears on the right side in FIG. 1) will be described below.

At the front end of the side surface of the armrest 1, a storage recess 3 for storing the monitor 2 is provided at a depth substantially the same as the thickness of the monitor 2. Further, a recess 4 is formed in the upper part of the front end of the storage recess 3, and the first rotating member 6 is rotated around the screw through a screw as a first hinge shaft 5 extending in the vertical direction. Is rotatably attached. The first rotating member 6 can rotate in the range of 0 to 120 degrees, and since it has an appropriate frictional force between itself and the first hinge shaft 5, it can be rotated at any angle. It can be stopped.

A second rotating member 8 is attached to the side surface of the first rotating member 6 via a screw as a second hinge shaft 7 extending in the horizontal direction so as to be rotatable around the screw. The second rotating member 8 can rotate in the range of 0 ° to 90 °, and since it has an appropriate frictional force with the second hinge shaft 7, it is usually 90 °. It can be stopped at the rotated position.

The monitor 2 is attached to the second rotating member 8 via a screw serving as a third hinge shaft 9 extending in a direction perpendicular to the screw 7.
Is rotatably mounted around the screw. That is, two convex plates 10 are provided on the second rotating member 8 so as to be spaced apart from each other, and a groove into which the convex plate 10 is fitted is attached to the bottom plate of the monitor 2.
11 is formed, and the third hinge shaft 9 is passed through the convex plate 10 and the groove 11. Then, since the claw 12 provided at the tip of the convex plate 10 is engaged with the engagement end 13 provided in the groove 11, the rotation limit of the monitor 2 is regulated, so that the rotation range is 0 degree. It is ~ 45 degrees. Further, since an appropriate frictional force is given between the monitor 2 and the third hinge shaft 9,
The monitor 2 can be stopped at any angle.

Further, a finger-holding concave portion 14 is provided on the top surface of the monitor 2, and a finger-inserting concave portion 15 is provided on the rear edge of the storing concave portion 3 of the armrest 1. It is easy to take out.

The operation and effect of the present embodiment configured as described above will be described separately when the monitor is taken out and when it is stored.

(1) First, when the monitor 2 is taken out and used, it is operated as follows.

As shown in FIG. 1, the monitor 2 housed in the housing recess 3 at the front end of the side surface of the armrest 1 is rotated around the first hinge shaft 5 as shown in FIG. At the same time as taking it out from the monitor, the head swing angle of the monitor 2 is adjusted to an angle that is easy to see. At this time, the screen 2a of the monitor 2 is lying sideways.

Next, as shown in FIG. 5, the monitor 2 is rotated around the second hinge shaft 7 to raise the screen 2a of the monitor 2 substantially vertically.

Next, as shown in FIG. 6, the monitor 2 is rotated around the third hinge shaft 9 to adjust the tilt angle of the monitor 2 to an angle that is easy to see.

As described above, since the monitor 2 of this embodiment is located at the front end of the side surface of the armrest 1 that can be reached by the seated person, the monitor 2 can be taken out in a natural sitting posture without leaning forward.
Even an inexperienced seated person can take out the monitor 2 and adjust its tilt angle and swing angle by simply performing three rotation operations whose movements are simple and small as described above. Easy and easy to do.

(2) When storing the monitor 2, operate as follows.

As shown in FIG. 5, the monitor 2 is rotated around the third hinge shaft 9 to return the tilt angle of the monitor 2 to the original substantially vertical state. In the case of the present embodiment, this operation can also be performed together in the last operation.

Next, as shown in FIG. 4, the monitor 2 is rotated around the second hinge shaft 7 to tilt the screen 2a of the monitor 2 sideways.

Next, as shown in FIG. 1, the monitor 2 is rotated around the first hinge shaft 5 and fitted into the storage recess 3 to be stored.

Therefore, the monitor 2 of the present embodiment can be stored in a natural sitting posture, and even if the user is unfamiliar, the movement is simple and small as described above three times or more. It can be stored easily and easily by performing two rotation operations (when the operations are performed together). Also, the monitor has its screen 2a
Since the side only fits into the storage recess 3, the heat radiation of the monitor 2 immediately after storage is hardly disturbed.

The present invention is not limited to the configuration of the above-described embodiment, and may be embodied by being arbitrarily modified within the scope not departing from the spirit of the invention as follows.

(1) The first to third hinge shafts are not limited to the screws,
Any known or modified hinge shaft may be employed. For example, instead of a shaft body such as a screw, only the both ends may be rotatably supported, and the space between them may exist as an axis line (space).

(2) As a mechanism for stopping the rotation around the first to third hinge axes at an arbitrary angle, for example, a click stop mechanism may be provided instead of the friction force.

[Advantage of the Invention] Since the seat monitor device of the present invention is configured as described above, the monitor can be taken out and stored without any hesitation by a simple and easy operation in a natural sitting posture. It is possible to adjust the tilt angle and the swinging angle of the monitor to an angle that is easy to see, and there is an excellent effect that there is no fear of hindering heat radiation immediately after the monitor is stored.
