However, in the above-described conventional structure, when the turning angle of the monitor 1 in the left-right direction is changed, the monitor 1 and the instrument panel IP interfere with each other. It is necessary to secure a gap S for the maximum turning angle in advance.
For this reason, since the monitor 1 protrudes from the instrument panel IP by a considerable dimension S, there has been a problem that the monitor 1 becomes an obstacle for the driver. If the dimensions of the monitor 1 and the instrument panel IP are reduced to solve this problem, the turning angle in the left-right direction is reduced, and conversely, the display of the monitor is difficult to visually recognize.

The present invention has been made in view of the above-mentioned problems associated with the prior art, and is excellent in the degree of freedom in the turning angle in the left-right direction, and has a very small amount of protrusion from an instrument panel or the like. It is an object of the present invention to provide a monitor fixing device.

A pin P that engages with the right guide groove 7R of the turning member 6 in the drawing.
2 are similarly provided, and these two pins P1, P2
Reference numeral 2 is a turning fulcrum of the present invention. Further, a pin 10 that engages with the guide 11 of the turning member 6 is fixed directly or indirectly. The two pins P1 and P2 are provided close to the front side of the instrument panel IP, that is, the back side of the monitor 1, and are separated by a predetermined distance. The pin 10 is provided substantially at the center of the pins P1 and P2 and fixed to the inner side of the case 2. The pin 10 and the guide 11 constitute the emergence control means of the present invention.

On the other hand, a pair of guide grooves 7 (general term for 7R and 7L) for engaging the pins P1 and P2 are formed in the turning member 6.
Are formed, and one guide groove (for example, FIG. 1A)
, The right guide groove 7R) is formed on the circumference of a radius r1 centered on the other pin P1, and the other guide groove (for example, the left guide groove 7L in FIG. 1A) is
It is formed on the circumference of a radius r2 centered on one pin P2. Therefore, when the monitor 1 is turned to the left, for example, the turning member 6 turns with the left pin P1 as a turning fulcrum, and the other pin P2 is guided along the right guide groove 7R.

Another guide groove 11 which engages with the pin 10 is formed in the turning member 6, and a circumferential locus centered on the pin P1 and a circumferential locus centered on the pin P2 are synthesized. The pin 10 and the guide groove 11
Are prevented from unnecessarily protruding and retracting from the case 2. However, a pair of pins P
Depending on the setting positions of the guide grooves 1 and P2 and the guide grooves 7R and 7L, the swinging member 6 can also be prevented from protruding and retracting by using them. In this case, the pins 10 and the guide grooves 11 can be omitted.

As shown in FIG. 1B, recesses 9 for temporarily fixing the turning position of the turning member 6 are formed on the back surface of the turning member 6 at predetermined intervals. The pivoting member 6 is fixed in position by fitting the spring-biased ball 12 of the click 8 fixed to the case 2 side. These click 8, recess 9 and ball 1
2 constitutes the holding means of the present invention.

The monitor 1 having the display surface 1a is fixed to the tip of the turning member 6. Next, the operation will be described.

As shown in FIG. 2, when the monitor 1 is turned to the left from the front position, the revolving member 6 starts revolving around the left pin P1 as a revolving fulcrum, and the other pin P2 becomes the guide groove 7R.
You will be guided along. The pin 10 is guided along the guide groove 11. At this time, the ball 12 of the click 8
Fits into any one of the recesses 9 formed on the back surface of the turning member 6, where the position is temporarily fixed.

On the other hand, when the monitor 1 is turned rightward from the front position, the revolving member 6 starts revolving around the right pin P2 as a revolving fulcrum, and the other pin P1 is guided along the guide groove 7L.

As described above, when the monitor 1 is turned to the left, the left pin P1 becomes a turning fulcrum, and when the monitor 1 is turned to the right, the right pin P2 becomes a turning fulcrum. Therefore, since the pin closer to the turning direction becomes the turning fulcrum, the turning angle is increased although the moving range of the end 1b of the monitor 1 shown in FIG. 2 is significantly reduced. Further, since the left and right pivot points are as close as possible to the back of the monitor 1, the pivot operation is performed at a position close to the instrument panel IP, which may hinder driving and operation of other parts. Absent. In addition, since the angle at which the turning member 6 is pushed in the turning operation is in the 90 ° direction (the front-back direction of the vehicle), the monitor 1 can be turned smoothly.

In addition, when the monitor 1 is not used, if the monitor 1 is directed to the front, the amount of protrusion from the instrument panel IP is extremely small, and there is no hindrance to the occupant. In addition, by using the plate-shaped turning member 6, a thin space (for example, a thickness of about 5 mm) is provided.
The rotation mechanism can be configured in the inside, and becomes a thin fixing device, which is particularly suitable for mounting on an instrument panel IP or the like.

Further, when the revolving member 6 is revolved, the other pin 10 is also engaged with the guide groove 11, so that the revolving member 6 is prevented from coming out of the case 2,
The vehicle turns smoothly without rattling.

As shown in FIG. 3, the end 1b of the monitor 1
Is given by the left turning operation from the front position, y = Rx
Cos (θ + θ ₀ ) −Rx · cos θ ₀ approaches the instrument panel IP side. Here, Rx is the distance from the turning fulcrum P to the monitor end 1b, θ is the turning angle, and θ ₀ is the front direction of the monitor end 1b with respect to the turning fulcrum P when the monitor 1 is facing the front (FIG. The angle of inclination from the (medium + Y direction).

As is apparent from the above equation, by setting the turning fulcrum P to a position in the + Y direction in order to shorten Rx,
The amount y of the monitor end 1b approaching the instrument panel IP can be reduced. With this technique,
The clearance between the instrument panel IP and the monitor end 1b can be designed. The clearance at the time of turning right can be designed in a similar manner.

Further, when the turning angle θ is determined and the rear end of the monitor 1 is cut as shown by the phantom line in FIG. 2, the monitor 1 does not come into contact with the instrument panel IP at all, and the predetermined turning angle θ Can be secured.

The embodiments described above are described for facilitating the understanding of the present invention, and are not described for limiting the present invention.

For example, the guide groove 7 or 11 does not need to have a shape penetrating the turning member 6, but as shown in FIG. 4, the guide groove 7 or 11 has a bottomed groove shape, and the pins P1 and P2 Alternatively, a structure in which 10 is fitted can be adopted. With this configuration, the pins P1 and P2 are not exposed on the upper surface of the turning member 6, so that
The guide groove 7 with grease is not shown to the occupant, and the appearance is improved. Also, the guide groove 7 or 1
Instead of 1, it is also possible to adopt a structure in which ribs facing each other are provided and the pins P1, P2 or 10 are guided between the pair of ribs.

Further, the structure of the click 8 and the recess 9 is shown in FIG.
There is no limitation to what is shown in (B). For example, as shown in FIG. 5, the turning member 6 is provided with a rib 6a,
The recess 9 and the click 8 may be provided inside this. In the present embodiment including the rib 6a, the turning member 6 also functions as a cover.

[0032]

As described above, according to the fixing device for a vehicle-mounted monitor according to any one of the first to third aspects, the display surface of the monitor tilts in the left-right direction about the turning fulcrum that changes in the turning direction. Therefore, the left and right turning angles of the display surface of the monitor are increased, and the left and right turning fulcrums are brought as close to the back of the monitor as possible, thereby realizing a swinging operation in which the amount of projection of the monitor is minimized. In addition, when the monitor is not used, if the monitor is directed to the center, the amount of protrusion from the instrument panel is extremely small, and there is no hindrance to the occupant.
