EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated using drawing.
(First embodiment)
First, a first embodiment of the present invention will be described with reference to FIGS. 1-9. In the following description, up, down, front, rear, left, and right refer to the directions of up, down, front, rear, left, and right, that is, the orientation of the automobile 1. Up, down, forward, backward, left and right directions when turned on. This also applies to the second embodiment described later. First, with reference to FIGS. 1 and 2, the front of the passenger compartment 1a of the automobile 1 according to the first embodiment and the half mirror device 5 will be individually described.

First, the front side of the compartment 1a will be described. As is clear from FIGS. 1 and 2, an overhead console 4 is assembled in the center of the ceiling 2 of the automobile 1 by the windshield 3 . This overhead console 4 is provided with a map lamp and an accessory case (both not shown). Thus, the occupants in the driver's seat and the passenger's seat (both not shown) can view the map in the vehicle interior 1a and store small items such as sunglasses in the overhead console 4 even at night.

Next, the half mirror device 5 will be explained. As is clear from FIGS. 3 and 4, the half-mirror device 5 mainly comprises a mounting base 10 and a half-mirror body 20. As shown in FIG. The mounting seat 10 and the half mirror main body 20 will be individually described below.

First, the mounting seat 10 will be described. The mounting seat 10 mainly includes a pair of left and right bases 11, a lever 12, an arm 13, and a pair of left and right support arms 14 (see FIGS. 5 and 6). The left and right bases 11 are formed with elongated holes 11a extending in the front-rear direction, into which left and right projecting shafts 13c of the arm 13, which will be described later, can be inserted. Further, the left and right bases 11 are formed with through holes 11b through which shafts 16a of knobs 16, which will be described later, can pass.

The lever 12 is formed with an overhanging portion 12a that overhangs to the left and right. In addition, a long hole 12b is formed in the side surface of the lever 12 so as to extend through the left and right. A notch groove 12c communicating with the long hole 12b is formed on the surface of the lever 12. As shown in FIG. A compression spring 12d is assembled in the cutout groove 12c. One end 12e of the assembled compression spring 12d is hooked on the inner surface of the notch groove 12c, and the other end 12f is hooked on the outer peripheral surface of a round pin 13b of the arm 13, which will be described later.

The arm 13 is formed with a round pin 13b bridging one end 13a of the arm 13 from side to side. Both ends of the round pin 13b form a columnar projecting shaft 13c projecting from the bridged arm 13. As shown in FIG. The arm 13 has a half-split structure, and is assembled to the lever 12 such that the round pin 13b is inserted into the elongated hole 12b of the lever 12. As shown in FIG. As a result, the elongated hole 12b of the lever 12 and the round pin 13b of the arm 13 are movable relative to each other.

The arm 13 is attached to the left and right bases 11 in such a manner that the left and right protruding shafts 13c are inserted into the long holes 11a of the left and right bases 11, respectively. As a result, the elongated hole 11a of the base 11 and the projecting shaft 13c of the arm 13 are movable relative to each other. One end 14 a of the left support arm 14 is pivotally attached (rotatably attached) to the left base 11 via a torque hinge 15 . The other end 14b of the left support arm 14 is pivotally attached (rotatably assembled) via a rotation shaft 13f formed on the left side of the other end 13d of the arm 13. As shown in FIG. Similarly, one end 14 a of the right support arm 14 is pivotally attached to the right base 11 via a torque hinge 15 .

The other end 14b of the right support arm 14 is pivoted via a rotary shaft 13f formed on the right side of the other end 13d of the arm 13. As shown in FIG. By being pivoted in this manner, the half mirror body 20 assembled to the arm 13 of the mounting seat 10 via the rod 30 as described later can move forward and backward with respect to the base 11 via the torque hinge 15. can be oscillated. A shaft 16a of a left knob 16 is fixed to the left projecting portion 12a of the lever 12 through a through hole 11b of the left base 11. As shown in FIG. Similarly, the shaft 16a of the right knob 16 is fixed to the right projecting portion 12a of the lever 12 via the through hole 11b of the right base 11. As shown in FIG. The mounting seat 10 is configured as described above.

Next, the half mirror main body 20 will be explained. The half mirror main body 20 includes a main body case 21 whose longitudinal direction is the horizontal direction; and a mounting portion 23 assembled via a plurality of screws (not shown) so as to be sandwiched between the display 22 and the display 22 .

This display 22 has a mirror function that acts as a mirror and a display function that displays an image of the rear of the automobile taken by a camera (not shown). Therefore, when the display 22 displays an image of the rear of the automobile photographed by the camera, it functions as display means for displaying the image of the rear (the display function operates). On the other hand, the display 22 functions as a mirror (mirror function operates) unless the image of the rear of the automobile photographed by the camera is displayed. The half mirror main body 20 is configured as described above.

The half mirror main body 20 configured in this way is attached to the arm 13 of the mounting seat 10 via the rod 30 . The rod 30 is composed of a front shaft portion 31, a rear shaft portion 32, and a ball joint 33 connecting them. The front shaft portion 31 is fixed to the mounting hole 13 e of the arm 13 of the mounting seat 10 , and the rear shaft portion 32 is fixed to the mounting hole 23 a of the mounting portion 23 of the half mirror main body 20 .

Therefore, the orientation of the half mirror body 20 can be adjusted through the ball joint 33 so that the display surface 22a of the display 22 of the half mirror body 20 faces the passenger in the driver's seat. This description translates to "the half-mirror main body in an advanced state with respect to the mounting seat is rotatable about an axis having the longitudinal direction as an axial direction with respect to the mounting seat." Equivalent to That is, the orientation of the half mirror main body 20 can be adjusted with respect to the mounting seat 10 .

The half mirror device 5 is composed of the mounting seat 10 and the half mirror main body 20 . The mounting seat 10 of the half-mirror device 5 configured in this way is mounted on the windshield 3 near the overhead console 4 with an adhesive (not shown) (see FIG. 1). In this mounted state, the mounting seat 10 is covered with a cover 6 made of resin. That is, left and right engaging claws 6a formed on the cover 6 are assembled into engaging holes (not shown) formed on the left and right sides of the front end of the overhead console 4 while covering the mounting seat 10. As shown in FIG. (See Figure 2).

Next, the operation of the half mirror device 5 described above will be described with reference to FIGS. In this description, as shown in FIG. 7, the half mirror main body 20 of the half mirror device 5 is in the retracted state with respect to the mounting seat 10. As shown in FIG. In this retracted state, the display 22 of the half mirror main body 20 can be installed at a line-of-sight position far from the occupant in the driver's seat. Therefore, it is possible to suppress the movement of the line of sight of the occupant in the driver's seat looking at the display 22 . Also, in this retracted state, the compression spring 12d is in a steady state.

From this retracted state, the knob 16 is turned forward. Then, the lever 12 begins to rotate forward about the shaft 16 a of the knob 16 . As the lever 12 rotates, the round pin 13b of the arm 13 moves from the front end of the long hole 11a of the base 11 toward the rear end. Therefore, the half mirror main body 20 advances from the mounting seat 10 . That is, the half mirror main body 20 advances toward the rear with respect to the mounting seat 10 . When moving forward, the half mirror main body 20 swings in the front-rear direction by the left and right support arms 14 .

Also, due to the rotation of the lever 12, the projecting shaft 13c of the arm 13 moves from the upper end of the long hole 12b of the lever 12 toward the lower end while bending the compression spring 12d from the steady state. Incidentally, when the round pin 13b of the arm 13 reaches the center of the elongated hole 11a of the base 11, the compression spring 12d is in a state of maximum deflection (see FIG. 8). Then, when the knob 16 is turned forward until the round pin 13b of the arm 13 reaches the rear end of the elongated hole 11a of the base 11, the half mirror body 20 advances backward with respect to the mounting seat 10. It switches to the advanced state (see FIG. 9).

The length of the elongated hole 11a of the base 11 is such that the line C connecting the overhanging shaft 13c and the rotating shaft 13f of the arm 13 is parallel to the mounting seat 10 when the half mirror main body 20 is retracted and advanced. (see FIGS. 7 and 9). Thereby, even if the half mirror main body 20 is switched to the advanced state, the tilt in the front-rear direction of the display surface 22a of the display 22 of the half mirror main body 20 can be made the same as that in the retracted state. That is, even if the half mirror main body 20 is in the retracted state or advanced state, the tilt of the display surface 22a of the half mirror main body 20 is the same (in the first embodiment, as shown in FIGS. 7 and 9, along the line). Therefore, it is possible to prevent deterioration of the visibility of the occupant in the driver's seat.

Moreover, when it switches to this advanced state, the bent compression spring 12d will be returned to a normal state. In this manner, the half mirror main body 20 can be advanced backward with respect to the mounting seat 10 . That is, the occupant in the driver's seat can pull out the half mirror main body 20 to the near side. If it can be pulled out in this way, the pulled-out half mirror main body 20 is separated from the windshield 3, so that the display surface 22a of the display 22 of the half mirror main body 20 faces the occupant in the driver's seat. Even if the orientation of the main body 20 is adjusted, the display 22 of the adjusted half mirror main body 20 does not interfere with the windshield 3.

In order to return the half mirror main body 20, which has been switched to the advanced state (see FIG. 9) with respect to the mounting seat 10, to the retracted state, the knob 16 described above may be turned to the back side. Then, an operation opposite to the operation described above, that is, an operation is performed in which the half mirror main body 20 retreats forward with respect to the mounting seat 10 (see FIG. 8). Therefore, the half mirror main body 20 can be returned to the retracted state with respect to the mounting seat 10 (see FIG. 7).

Further, when the return is performed, if the orientation of the half mirror body 20 is adjusted so that the display surface 22a of the display 22 of the half mirror body 20 faces the occupant in the driver's seat, the body of the half mirror body 20 The substantially U-shaped guide cover 21 b of the case 21 interferes with the substantially U-shaped edge 6 b of the cover 6 . Therefore, this adjusted orientation is returned to the state before adjustment. This description is referred to in the scope of claims, "When the half mirror main body in the advanced state with respect to the mounting seat is returned to the retracted state, the half mirror main body is tilted around the axis with the front-rear direction as the axial direction. Even if it is adjusted to , it is returned so that this inclination disappears.

The half mirror device 5 according to the first embodiment of the present invention is constructed as described above. According to this configuration, when the knob 16 is rotated, the half mirror main body 20 can move back and forth with respect to the mounting seat 10 . Therefore, when the half-mirror body 20 is retracted with respect to the mounting seat 10, the display 22 of the half-mirror body 20 can be installed at a line-of-sight position far from the occupant in the driver's seat. Also, the orientation of the half mirror main body 20 can be adjusted with respect to the mounting seat 10 . Therefore, when the half mirror main body 20 is advanced with respect to the mounting seat 10, the advanced half mirror main body 20 is separated from the windshield 3, so that the half mirror main body 20 is prevented from interfering with the windshield 3. direction can be adjusted. Therefore, when using the display 22 of this half mirror main body 20 as a mirror function, the direction of this display 22 can be adjusted.

Further, according to this configuration, when the half mirror main body 20 is set in the retracted state or advanced state with respect to the mounting seat 10, the compression spring 12d is in a steady state. Further, when the half mirror main body 20 is placed in the intermediate state between the retracted state and the advanced state with respect to the mounting seat 10, the compression spring 12d is in a bent state. With this configuration, the half mirror main body 20 is biased by the compression spring 12d so as to be held in a facing state or an advanced state with respect to the mounting seat 10. As shown in FIG. Therefore, it is possible to prevent the half mirror main body 20 from being held halfway between the retracted state and the advanced state. Therefore, the half mirror main body 20 can always be held in the retracted state or advanced state.

Further, according to this configuration, the half mirror main body 20 can swing in the front-rear direction with respect to the base 11 via the torque hinge 15 . Therefore, even if the half mirror main body 20 is in the retracted state or advanced state, the inclination of the display surface 22a of the half mirror main body 20 is the same (in this example, as shown in FIGS. state). Therefore, it is possible to prevent deterioration of the visibility of the occupant in the driver's seat. Further, by using the torque hinge 15, rattling during running of the automobile 1 can be absorbed.

Further, according to this configuration, when returning the half mirror body 20 to the retracted state, the orientation of the half mirror body 20 is adjusted so that the display surface 22a of the display 22 of the half mirror body 20 faces the occupant in the driver's seat. Then, the substantially U-shaped guide cover 21 b of the body case 21 of the half mirror body 20 interferes with the substantially U-shaped edge 6 b of the cover 6 . Therefore, the body case 21 of the half mirror body 20 is guided along the edge 6 b of the cover 6 . Therefore, when the half mirror main body 20 is returned, the direction of the half mirror main body 20 being adjusted can also be returned. As a result, it is possible to save the trouble of returning the direction of the half mirror main body 20 .

Further, according to this configuration, the length of the elongated hole 11a of the base 11 is such that the line C connecting the extension shaft 13c of the arm 13 and the rotation shaft 13f is such that the half mirror main body 20 is retracted with respect to the mounting seat 10. It is set so as to be parallel to the advanced state (see FIGS. 7 and 9). Therefore, even if the half mirror main body 20 is in the retracted state or advanced state, the inclination of the display surface 22a of the half mirror main body 20 is the same (in the first embodiment, as shown in FIGS. along the line). Therefore, it is possible to prevent deterioration of the visibility of the occupant in the driver's seat.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. 10-14. The half mirror device 105 of the second embodiment has a simplified structure as compared with the half mirror device 5 of the first embodiment already described. In the following description, members having the same or equivalent configuration as the members described in the first embodiment are denoted by the same reference numerals in the drawings, thereby omitting redundant description.

The half-mirror device 105 of the second embodiment is mainly composed of the mounting seat 10 and the half-mirror body 20, like the half-mirror device 5 of the first embodiment. However, in the half mirror device 105 of the second embodiment, as is clear from FIGS. 10 and 11, the protruding shaft 13c of the arm 13 has a quadrangular prism shape. Moreover, the half mirror device 105 of the second embodiment does not require the left and right support arms 14 and the torque hinges 15 .

The half mirror device 105 according to the second embodiment of the invention is constructed as described above. According to this configuration, it is possible to obtain the same effects as those of the half mirror device 5 of the first embodiment (see FIGS. 12 to 14). As described above, since the protruding shaft 13c of the arm 13 is in the shape of a quadrangular prism, the same effects as those of the half mirror device 5 of the first embodiment can be obtained without the need for the left and right support arms 14. be able to.

The contents described above are merely related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.

In each embodiment, as the display function of the display 22, the function of displaying the image of the rear of the car captured by the camera has been described. However, the present invention is not limited to this, and the display function of the display 22 may be a function of displaying images (for example, movies) stored in a storage medium (not shown). In this way, when the display function of the display 22 is the function of displaying images stored in a storage medium (not shown), the half mirror main body 20 can be in either a retracted state or an advanced state with respect to the mounting base 10. I don't mind. For example, while resting in the car 1, the display 22 of the half-mirror body 20 allows the user to watch a movie or the like.

Moreover, in each embodiment, a tension spring may be used without using the compression spring 12d. Further, in the second embodiment, the knob 16 may be slidable in the front-rear direction.
