Description

The present invention relates to a system for automatically storing an openable display device for providing information to passengers in an aircraft or the like when a passenger's head or the like touches a monitor.

2. Description of the Related Art In recent years, there are an increasing number of transportation means such as airplanes, trains, buses, passenger ships, and the like that are provided with display devices for providing information such as passengers enjoying images. Further, there is an increasing demand for enjoying various images individually in the transportation means, and there is a demand for providing a display device having a light and thin monitor that takes up as little space as possible. For this reason, in passenger aircraft in particular, various types of monitors can be used by pulling out the monitor housed in the lower part of the luggage rack at the ceiling of the passenger seat and using it for video distribution services, etc. The configuration is presented. Such an open / close display device is driven by a motor when the power switch of the device is turned on, and a rectangular flat plate-shaped monitor rotates around its one side and is pulled out from the ceiling storage portion above the seat, After the image is displayed and used at an angle that is easy for the passenger to see, the device is turned and stored again in the original ceiling when the power switch of the device is turned off.
However, safety is the most important aspect for all aircraft, and the display device is no exception. When an impact is applied to the passenger's head while using the monitor as described above, It is required to immediately retract the monitor into the storage unit.
To realize the above-mentioned operation, an open / close type using a mechanism that detects the force in the rotational direction of the monitor using an angle sensor and a slip mechanism that slips when a predetermined amount of force is applied in the rotational direction. Display devices have been proposed.

However, a force detection mechanism using an angle sensor may malfunction in a vibrating environment such as an airframe. Furthermore, a complicated electrical circuit for using the sensor and a link mechanism for transmitting an external force to the sensor are required.
In order to solve such problems, the present invention uses a method in which a display device is accommodated when a load is applied by a push switch without a link or the like when a passenger collides with a monitor. An object of the present invention is to provide an open / close type display device that is rotated and automatically stored in a shroud regardless of vibration.

In order to achieve the above-described object, a display device that is operatively mounted between a storage position and a screen viewing position, a holding mechanism that holds the screen viewing position of the display device, and storage of the display device And a storage mechanism for performing the above. In addition, the display device includes a pressure switch that is attached near the outer periphery of the back surface and detects a load, and a back plate that transmits the load to the pressure switch, and the display device is accommodated when the load is applied to the pressure switch. It is characterized by being.
Furthermore, the pressing switch may be arranged at four corners on the back surface.
Further, a spring mechanism that pushes up the back plate may be disposed on the back plate.
By adopting such a configuration, there is an effect that it is possible to prevent malfunctioning in an environment in which the airframe or the like to which the openable display device is attached vibrates.

According to the open / close display device of the present invention, when an impact is applied to the monitor part by a passenger's head or the like during use of the monitor part, the monitor part is integrated with the monitor part regardless of the place where the impact is applied to the back plate. An external force can be detected by an external force detection mechanism using a push switch, and the monitor can be immediately pulled into the storage unit.

It is a side view which shows the state which attached the monitor apparatus which concerns on embodiment of this invention to the ceiling of a passenger aircraft. It is the force detection mechanism schematic of the monitor apparatus which concerns on embodiment of this invention. It is a figure of the monitor apparatus accommodation state shown by the AA cross section of FIG. 2 which concerns on embodiment of this invention. It is a figure of the monitor apparatus expansion | deployment state shown by the AA cross section of FIG. 2 which concerns on embodiment of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, what is shown in FIG. 1 is a passenger cabin 1 inside a passenger aircraft. Seats 4 are attached to the floor 2 at regular intervals so that passengers can sit there. 5 is a window. A monitor 6 is attached to the ceiling 3. The monitor 6 includes a liquid crystal panel 7, a frame 16 that supports the liquid crystal panel 7, and a back plate 15 (see FIG. 2). Further, a shroud 8 in which the monitor 6 is stored at the time of storage is provided. Here, the case of a passenger aircraft will be described here as an example, but the present invention is not limited to an aircraft, and can be applied to various transportation means such as trains, buses, passenger ships and the like.
FIG. 3 is a cross-sectional view taken along line AA of FIG. 2 showing the storage state of the monitor, and FIG.
Referring to FIG. 3, the monitor 6 as a whole has a rectangular flat plate-like shape and has a panel-like display portion 7 such as an LCD. It is rotatably supported by bearings on both sides, is used by being rotated and developed at a screen angle that is easy to see for passengers by a drive mechanism 11 disposed above, and is stored in the shroud 8 again after use.
Next, a specific configuration of the present embodiment will be described. In the monitor 6, support shafts 9 provided at both ends near one side are rotatably supported by bearings on both sides of the shroud 8, and one end portion 10 </ b> A of the link 10 attached to the support shaft 9 is rotatable. It is connected to. The other end 10 </ b> B of the link 10 is connected to a connecting block 13 that is connected to the ball screw shaft 12 of the drive mechanism 11. The link 10 is a member for connecting the connecting block 13 and the ball nut 14 to the monitor 6 to rotate the monitor 6. The ball nut 14 moves linearly by the rotation of the ball screw shaft 12. The ball screw shaft 12 is arranged so that the axis of the ball screw shaft 12 is orthogonal to the axis of the support shaft 9 of the monitor 6. By moving linearly in a direction perpendicular to the support shaft 9 of the monitor 6, the monitor 6 is rotated and deployed and stored.
The rotatable monitor 6 may have an electromagnetic brake that holds the fully open position. Further, a spring that drives the monitor 6 from the fully open position to the retracted position may be provided.
Next, the external force detection mechanism will be described. The external force detection mechanism includes a frame 16 that supports the display unit 7 of the monitor 6, a back plate 15, and a conductor 17 provided therebetween. The external force detection mechanism is connected to the monitor 6 so as to rotate and deploy together with the monitor 6. The external force detection mechanism includes a frame that supports a liquid crystal provided with a contact portion such as metal and a back plate provided with a contact portion such as metal. Contact portions such as metal are arranged at the four corners of the frame and the back plate in order to come into contact with any part of the back plate (see FIG. 2). In the state where the monitor 6 is opened or is about to open, the drive mechanism is energized when the conductors come into contact with each other, and the monitor is automatically stored. In the force detection mechanism, a mechanical switch may be arranged on the frame 16 or the back plate 15 instead of a contact point of metal or the like. A spring mechanism 18 is provided between the back plate 15 and the frame 16 in order to provide a certain space.

  The present invention relates to an open / close display device, and more particularly to a system that automatically stores when a passenger's head or the like touches a monitor, and the monitor of the open / close display device is opened or rotated and deployed. Provided is a retractable system that automatically retracts by contact between conductors when an external force is applied to the back plate of the monitor. The present invention can be applied to an aircraft retractable display device.
