本発明は自動車用のバツクミラーに関するもの
であつて、特に車体のドアパネル上部又は三角窓
隅角部にとりつけて使用するバツクミラーに係
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rearview mirror for an automobile, and more particularly to a rearview mirror that is attached to the upper part of a door panel or the corner of a triangular window of a vehicle body.
一般に汎用されているドアミラーには大別して
２種類あり、その一つはドアパネル外面にロツド
エンド軸受を固着してバツクミラーを取付けたも
のであり、ミラーの反射角度を調節するに当つ
て、ミラーボデー自体を直接動かさねばならない
ので、車室内からその角度を調節することはでき
なかつた。 Generally speaking, there are two types of door mirrors that are commonly used. One type has a back mirror attached to the outside of the door panel with a rod end bearing fixed to it. In order to adjust the reflection angle of the mirror, the mirror body itself must be adjusted. Since it had to be moved directly, it was not possible to adjust the angle from inside the vehicle.

あつた。 The other type allows the reflection angle of the mirror to be adjusted remotely by rotating a handle on the passenger compartment side. For example, in West German Utility Model Publication No. 1899306, spherical sliding bearings are installed on the inner and outer surfaces of the door panel, a mirror body is attached to the outer spherical sliding bearing, and a lever is installed on the inner spherical sliding bearing to protrude into the passenger compartment. Furthermore, a universal joint is provided at the rod ends of both spherical plain bearings to connect them, and the angle of the mirror can be adjusted in two directions, the vertical axis and the horizontal axis of the vehicle body, with respect to the stem attachment part by rotating a lever. ing. Furthermore, in French Patent No. 2129234, the stay is rotatably installed in the horizontal direction within the stay, and the mounting shaft of the mirror body is supported at the outer tip of the cylinder shaft, and the end of the cylinder shaft on the passenger compartment side. A first operation handle for rotating the mirror body about the horizontal axis of the vehicle body is fixed to the cylindrical shaft, and a core shaft is inserted into the cylindrical shaft, and a bevel gear is provided at one end to mesh with the bevel gear of the mirror body mounting shaft. It is disclosed that the other end is provided with a second operating handle for rotating the mirror body about a vertical axis. However, with the methods disclosed in these publications, not only do angle adjustment operations tend to be unsmooth, but once the angle has been adjusted, the reflection angle cannot be maintained reliably, making it difficult to adjust the angle while driving. There was a problem in that the setting angle was likely to be distorted due to vibration and impact.

得んとしたものである。 The present invention enables the angle of the rearview mirror to be adjusted remotely by operating the handle on the passenger compartment side, and is a product that is easy to operate, has a compact structure, and can reliably maintain the set angle. This is what we were trying to achieve.

ない。 That is, the present invention provides a bracket on the outer surface of the stay and mounts a first spherical slide bearing to support the stem of the mirror body, and also mounts a second spherical slide bearing on the inner surface of the stay to protrude toward the passenger compartment. In addition, rods are installed vertically on both spherical sliding bearings, and the lower ends of both rods are connected by a lever mechanism using a four-bar link that makes the swing angle of the mirror body smaller than the operating angle of the operating handle. It is characterized by: In this way, the angle of the mirror body rotated via both lever mechanisms is always smaller than the apparent rotation angle of the operating handle, so the mirror angle can be finely adjusted. Furthermore, after setting the angle at one end, the adjusted mirror reflection angle is ensured by the combination of both spherical sliding bearings and the four-bar link, and there is no fear that the set angle will change due to running, vibration, etc.

のとされている。 Between the lower ends of the rods 8 and 23 of the first and second spherical plain bearings 4 and 5, a lever mechanism 6 formed by a four-bar link is interposed. That is, ring plates 28 and 29 are fixed to the lower ends of rods 8 and 23 using nuts or screws 26 and 27, respectively, and links 31 and 31 are connected using pins 30 at the ends of both ring plates. Since the link plate 28 on the first rod side is slightly longer than the second link plate 29, the rotation angle of the link 29 on the lower end of the first rod 8 is different from the rotation angle of the link 29 on the lower end of the second rod 23. The swing angle is always considered small.

The outer ring 19 has open square holes 24, 25 (Fig. 1,
(Fig. 3) with the handle mounting rod 22,
Since the link attachment rod 23 is inserted, the mirror angle can be adjusted smoothly without interfering with the horizontal direction of the handle and the left and right rotation of the handle shaft. Furthermore, since the movement is transmitted to the mirror body 2 via the double lever mechanism 6 which has a boosting effect, it is possible to perform delicate angle adjustment operations by making the mirror rotation angle smaller than the apparent rotation angle of the handle. Since the movement of the operating handle 21 and the direction of mirror inclination are in the forward direction in any of the above cases, the angle can be easily adjusted without erroneous operation.

ラーの傾きを調節できる。 The gear 45 meshes with the gear 52, and the gear 45 also meshes with the gear 52.
8 has a dimensional relationship that meshes with the gear 53.
Assuming that the center diameter of gears 45 and 53 is 1, gear 4
8, 52 with a center diameter of 2, and when the operating handle 21 is rotated by an angle of θ,
Since the gear 45 is supported by the guide 39 and does not rotate, the gear 52 rotates by an angle of θ. A gear 53, which is integrated with the gear 52 and has a center diameter of 1/2, rotates by an angle of θ. At this time, the rod 22, which is integral with the gear 48, the spherical shaft 21, the link plate 29, the link 31, both lever mechanisms 6, and the rod 8 rotate by 1/2θ angle. That is, the handle 21
When rotated by θ angle, mirror M becomes 1/2 on the X-X axis.
Rotate by θ angle. Mirror M has a spherical sliding bearing that provides sliding resistance to withstand wind pressure, vibration, etc.
If the torque required to move this is T, then when the rotation angle of the handle 21 is 2β, which is necessary to move the mirror M by β angle against the torque T, 1/2T is provided since the rotation reduction mechanism is interposed. (However, if losses in gear mechanisms, link mechanisms, etc. are ignored). In this embodiment, as in the case of FIGS. 1 to 5, the tilt of the mirror can be adjusted in the forward direction with the movement of the operating handle 21.

一層正確で容易なものとすることができる。 As described above, in the embodiment shown in FIGS. 6 to 8, since the rotation reduction mechanism is provided inside the handle 21, it is possible to rotate the mirror M with a small torque. In addition, an outer ring member 38 with a guide hole 39 is attached to the outside of the ball shaft 20, and a holding member 40 is also provided, so that the operating handle can be rotated in the horizontal direction and in the axial direction (X-X direction). This can be done completely separately, making it possible to adjust the angle of the mirror more accurately and easily.

効果を有している。 As described above, according to the present invention, spherical sliding bearings are provided on the inner and outer surfaces of the back mirror mounting stay, a stem and an operating handle are provided, and rods are provided hanging from both spherical sliding bearings. Since both lever mechanisms with four-bar links are interposed between the lower ends, the mounting angle of the rearview mirror can be adjusted remotely by rotating the operating handle inside the vehicle interior. The lever mechanism installed between the bearings ensures that the mirror swing angle is always smaller than the apparent rotation angle of the handle, making it possible to make subtle adjustments to the mirror installation angle, as well as to control the horizontal movement of the operating handle. Since the mirror always moves in the forward direction when rotating from side to side, it is easy to adjust the mirror angle without making any mistakes. In addition, once the angle is set, the adjustment angle can be secured as long as the handle is not operated by connecting the rod of the spherical slide bearing and both lever mechanisms, and the angle can be changed by driving like the conventional type. There is no risk that this will occur. Furthermore, by rotating one handle horizontally and axially, the rearview mirror can be accurately rotated in two axes, the vertical axis and the transverse axis of the vehicle, around one spherical axis. Moreover, it has excellent effects such as being able to provide a rear view mirror that has a compact structure as a whole and does not cause failure or damage.
