It is moved up and down between two possible positions, and when the display is in the storage position or the visible position, position detection means for detecting the position and control based on the position detection by the position detection means are performed. Drive means for rotationally driving the screw shaft.

According to the second aspect of the invention, the storage space is provided on a mesh rack of the vehicle.

[Operation] Therefore, according to the invention as set forth in claim 1, the drive means is controlled based on the position detection of the position detection means, and when the screw shaft is rotationally driven by the drive means, the moving member moves to the screw shaft. Is moved along the axis of. Then, turning force is applied to the support member, and the rotation of the support member causes the display to be stored in the storage space or exposed to a visible position.

According to the second aspect of the invention, by utilizing the space on the net rack of the vehicle as the storage space for the display, it is not necessary to provide a dedicated storage space on the ceiling of the vehicle, for example.

[Embodiment] An embodiment in which the vehicle display of the present invention is embodied in a bus vehicle will be described below with reference to FIGS.

As shown in FIG. 1, a storage box 5 is provided in a storage space 4 on each net shelf 3 provided on both sides of the ceiling portion 2 of the bus vehicle 1.
Are provided in plurality (three in this embodiment).
As shown in FIGS. 2 and 3, the storage box 5 is formed in a rectangular box shape with an opening at the bottom, and is fixed to a main body chassis (not shown) of the bus vehicle 1. A pair of support plates 6a and 6b are fixed to the side surfaces of the storage box 5 on both sides in the width direction of the storage box 5 by fixing members (not shown).

In the front part (left side in FIG. 3) of the storage box 5, a support shaft 7 is installed between the support plates 6a and 6b, and the support shaft 7 is arranged at a predetermined distance from each other and upwardly. A pair of extended arms 8 are rotatably attached. A connecting shaft 9 is installed above the arm 8, and a pair of support arms 10 are extended to the rear part (right side in FIG. 3) on both sides of the connecting shaft 9. A bracket 12 for supporting an upper portion of a television monitor 11 as a display is provided at the tip ends of the pair of support arms 10. In this embodiment, the arm 8, the connecting shaft 9, the support arm 10, and the bracket 12 constitute a support member.

Support plates 6a, 6 located on the tip side of the support arm 10
A pair of fixing plates 13a and 13b formed in a reverse channel cross section are fixed to the upper and lower positions of b. And
A motor 18 as a driving means is fixed to the fixed plate 13b located below via a base 17, and a shaft 18a protruding upward penetrates the fixed plate 13a. A drive gear 19 is fixed to the tip of the shaft 18a.

Behind the motor 18, fixed plates 13a, 13
A screw shaft 14 is rotatably erected between b and a transmission gear 16 is fixed to the tip of the screw shaft 14 protruding outside the fixed plate 13a and meshed with the drive gear 19. There is. Therefore, the drive gear 19 is rotated by the drive of the motor 18, and the screw shaft 1 is transmitted through the transmission gear 16.
4 is designed to rotate.

A moving member 15 having a rectangular parallelepiped shape is screwed onto the screw shaft 14 between the pair of fixing plates 13a and 13b, and is moved in the vertical direction by the rotation of the screw shaft 14. That is, guide rods 23 are provided on both sides of the moving member 15 in the width direction, and these guide rods 23 are rotatably fixed to the tip end portion of the support arm 10.
Therefore, since the relative rotation of the moving member 15 due to the rotation of the screw shaft 14 is restricted, the moving member 15 moves in the vertical direction with respect to the screw shaft 14, and the support arm 10 moves the connecting shaft 9 by the guide rod 23. It is designed to move up and down while rotating in the direction of the arrow A at the center.

In this embodiment, when the shaft 18a of the motor 18 rotates forward (clockwise), the moving member 15 moves downward, and when it rotates backward (counterclockwise), the moving member 1 moves.
5 is adapted to move upward.

As a result, the support arm 10 is rotated about the connecting shaft 9 by the drive of the motor 18, and the arm 8 is rotated about the support shaft 7 accordingly, and the arm 8 is provided at the tip of the support arm 10 via the bracket 12. TV monitor 11
Is moved up and down with respect to the storage box 5.

Further, actuating rods 20a and 20b are formed on the front and rear side surfaces of the moving member 15, respectively. One of the operating rods 20a comes into contact with the actuator 21a of the upper limit switch 21 as the position detecting means provided on the lower surface of the fixed plate 13a, and the other operating rod 20b is placed on the upper surface of the fixed plate 13b. The actuator 22a of the lower limit switch 22 as the provided position detecting means is brought into contact with the actuator 22a.

Therefore, the arm 8, the connecting shaft 9, the support arm 10, the screw shaft 14, the moving member 15, the guide rod 23, and the like constitute the elevator S.

Next, the operation of the elevator S configured as above will be described.

First, to watch a television in the bus vehicle 1, the motor 18 is driven by a remote controller (not shown) or the like to expose the television monitor 11 from the inside of the storage box 5. That is,
When the shaft 18a of the motor 18 is rotated in the forward direction by operating the remote controller, the drive gear 19 is rotated in the clockwise direction, so that the transmission gear 16 and the screw shaft 14 are rotated in the reverse direction. Then, since the moving member 15 moves downward with respect to the screw shaft 14, the guide rod 23 provided on the moving member 15 moves in the same direction, and the tip end of the support arm 10 moves in the direction of arrow A around the connecting shaft 9. It descends while rotating. As a result, bracket 1
The TV monitor 11 suspended and supported by 2 starts to be exposed from the storage box 5.

Further, when the TV monitor 11 descends, the support arm 1
Pulled by 0, the arm 8 rotates about the support shaft 7 in the direction of arrow B. Then, the operating rod 20b of the moving member 15
When the actuator contacts the actuator 22a of the lower limit switch 22, the limit switch 22 is turned off and the motor 1
8 stops automatically.

In this state, the TV monitor 11 is completely exposed from the storage box 5 and can be visually recognized.
Guests can watch TV. Further, the television monitor 11 is lowered with rotation, and in the state in which it is located at the visible position, the screen of the monitor 11 faces diagonally downward,
That is, the state is suitable for the passenger in the bus vehicle 1. Therefore, the passenger in the bus vehicle 1 can watch the television from the optimum angle even though the television monitor 11 is located above itself.

When the user wants to store the television monitor 11 in the storage box 5 after watching the television, the procedure is reversed. That is, by rotating the shaft 18a of the motor 18 in the reverse direction by operating the remote controller, the screw shaft 14 is rotated in the normal direction and the moving member 15 is raised. Then, the guide rod 23 causes the support arm 10 to rotate in the counter-A arrow direction about the connecting shaft 9 and the arm 8 to rotate in the counter-B arrow direction about the support shaft 7. And the motor 1
When the driving of No. 8 is continued and the moving member 15 continues to rise, the operating rod 20a of the moving member 15 contacts the actuator 21a of the upper limit switch 21, and the driving of the motor 18 is automatically stopped.

As a result, the TV monitor 11 can be completely stored in the storage box 5, and the TV monitor 11 can be moved up and down as needed, so that the aesthetic appearance of the bus vehicle 1 can be improved.

Further, if each of the television monitors 11 is individually operated to move up and down, only the customer who wants to watch the television can watch the television, which is a personal preference. By disposing a plurality of TV monitors 11 in the bus vehicle 1, the passengers in the rear part of the bus vehicle 1 can easily watch the television.

Also, in this embodiment, the TV monitor 11 is the support arm 1.
It is rotatably supported by 0 or the like, and is lifted or lowered as the support arm 10 or the like is rotated. The support arm 10 and the like are guided by the guide rod 23 to the moving member 15 screwed onto the screw shaft 14.
And is moved by moving the moving member 15 up and down as the screw shaft 14 rotates. That is, although the television monitor 11 has a relatively large weight, as in the present embodiment, by vertically moving the large television monitor 1 using the screw shaft 14, the vertical movement is stable. Can be done reliably.

Moreover, when the TV monitor 11 is moved up and down and is positioned at the storage position or the visible position, the position is detected by the upper limit or lower limit switches 21 and 22. Then, based on the position detection by the limit switches 21 and 22, the driving of the motor 18 is stopped, and the television monitor 11 is accurately stopped and held at the storage position or the visible position. Therefore, the TV monitor 11 is rotated beyond those positions, the monitor 11 collides with other members and is damaged, or the operation of each component forming the elevator S is unreasonably caused. There is no risk of damage.

In addition, in this embodiment, since the storage box 5 for storing the TV monitor 11 is provided in the storage space 4 on the net shelf 3 which is provided in advance in the bus vehicle 1, for example, the ceiling of the bus vehicle 1 It is not necessary to form a dedicated storage section for storing the TV monitor 11 in the section 2. Therefore, a space for housing the TV monitor 11 can be secured with an inexpensive structure, and the housing part of the TV monitor 11 itself is not exposed to the inside of the bus vehicle 1. The aesthetics of can be further improved.

[Advantages of the Invention] As described in detail above, according to the present invention, the display is raised and lowered as necessary so that the display is stored in the storage space and not exposed in the vehicle when the display is not used. Therefore, it is possible to improve the aesthetics of the vehicle and to provide a plurality of displays so that each of them can be individually raised and lowered, and thus it is possible to respond to a personal preference. Also, by moving the display up and down using the screw shaft, even if the display is relatively heavy, the up and down movement can be reliably performed in a stable state. Moreover, since the display is raised and lowered as it rotates, for example, when the display is placed on the ceiling side of the vehicle, the display is placed in a position where it can be seen, and it is optimally placed for viewing diagonally downward. It is possible to set the angle. Further, when the display is moved up and down to be in the storage position or the visible position, the position is detected by the position detection means, and the drive means is controlled based on the position detection, thereby making the display in the storage position or the visible position. It can be stopped and held in the correct position. Therefore, the display is rotated beyond those positions, the display collides with other members and is damaged, or the operation of each component forming the elevator is unreasonably damaged. There is no fear.
In addition, by using the net-like space of the vehicle as the storage space for the display, it is not necessary to provide a dedicated storage space on the ceiling of the vehicle, for example, and the space for storing the display can be provided at a low cost. In addition to securing the display, the storage of the display itself is not exposed to the inside of the vehicle, and the aesthetics of the inside of the vehicle can be further improved.
