Description

[Detailed Description of the Invention] This invention relates to a rearview mirror equipped with an appropriate angle adjustment mechanism and a mirror.

In conventional devices of this kind, the mirror holder that holds the mirror is generally part of the angle adjustment mechanism, so when the angle adjustment mechanism is assembled, the mirror is also assembled into the angle adjustment mechanism at the same time. .

However, in such conventional devices, the angle adjustment mechanism cannot be assembled independently from the mirror, making the assembly work complicated and troublesome.In addition, many angle adjustment mechanisms of the same standard are assembled, and these are assembled with various types. There were various drawbacks such as the inability to perform efficient assembly work such as assembling mirrors of the standard to produce products.

The object of this invention is to eliminate the drawbacks of the above-mentioned conventional rearview mirror and to provide a rearview mirror in which the mirror can be easily assembled to an angle adjustment mechanism assembled separately from the mirror.

This invention will be explained with reference to embodiments shown in the drawings.

FIG. 1 shows an embodiment of this invention, in which 1 is a housing;
2 is an appropriate manual angle adjustment mechanism provided in the housing 1; 3 is a holder plate provided at the front of the angle adjustment mechanism 2; and 4 is tilted upward, downward, leftward, rightward, and in a combined direction when the angle adjustment mechanism 2 is operated; is a mirror holder that holds the mirror 5 and is assembled to the holder plate 3 from the front.

The holder plate 3 is approximately annular as shown in FIGS. 3 to 7, and has a spherical portion 6 at the rear that cooperates with the angle adjustment mechanism 2, and an arcuate portion at the front periphery. protrusion? , 7, 7.7 and arcuate flanges 8.8.8.8 are formed adjacent to each other alternately in the circumferential direction.

As shown in FIG. 6, each protrusion 7 extends forward from the peripheral edge of the holder plate 3, has an outwardly bent bent portion 9 formed at the front end, and has a groove 10 formed inside the base. Therefore, each protrusion 7 can be deformed inwardly when subjected to an external force.

Each flange 8 has a protrusion 7. slightly rearward of each bend 9 as shown in FIG. 7. 7. As shown in Fig. 3.4, protrusions 11 for positioning are formed on the front surface only at l locations.

The mirror holder 4 has a shape that matches the shape of the mirror 5, as shown in FIGS. 8 to 11, and has a circular opening 12 formed in the center.

A flange portion 13 is formed around the entire front surface of the mirror holder 4, and an appropriate number of projections 14 (12 in FIG. 8) as shown in FIG. 2 are formed adjacent to the flange portion 13, and an opening An annular rib 15 is formed adjacent to the mirror holder 12, and the mirror 5 is held apart from the front surface of the mirror holder 4 by the flange portion 13, the protrusion 14, and the annular rib 15.

What is the diameter of the opening 12 of the holder plate 3 excluding the bent portion 9? , 7, 7.7, and has a fitting portion 1 corresponding to the protrusion 7, 7, 7°7 on its periphery.
6, 16, 16, 16 and flange 8. 8. 8. 8
Engaging portions 17, 17, 17, 17 corresponding to the above are formed adjacent to each other alternately in the circumferential direction.

Each fitting part 16 is configured such that when the mirror holder 4 is pressed against the holder plate 3, the front surface thereof is engaged with the bent part 9 of each protrusion 7 that deforms inwardly and passes through the opening 12. The rear surface of the engaging portion 17 comes into contact with each flange 8 when each fitting portion 16 is locked, so that the mirror holder 4 is tightly attached to the holder plate 3 in the front-rear direction.
It is designed to be assembled into.

In addition, the fitting parts 16, 16, 16, 16 and the engaging parts 17, 17
．． 17, 17 are shifted in the front-rear direction as shown in FIG. It can also be tightly assembled to the holder plate 3 in the circumferential direction.

Reference numeral 18 denotes a positioning recess formed in each engaging portion 17.

In the above rearview mirror, when the mirror holder 4 is pressed against the holder plate 3 of the angle adjustment mechanism 2 while aligning the convex part 11 and any one of the concave parts 18, each fitting part 16
The front surface of the mirror holder 4 is engaged with the bent portion 9 of each protrusion 7 passing through the opening 12, and the rear surface of each retaining portion 17 abuts on each flange 8, so that the mirror holder 4 can be rotated both in the front-rear direction and in the circumferential direction. It is also tightly assembled to the holder plate 3.

FIG. 12 shows another embodiment of this invention, in which the housing 1
, mirror holder 4, and mirror 5 are the same as those shown in FIG.

The holder plate 23, which is provided in the front part of a suitable electric angle adjustment mechanism 22 and is tilted upward, downward, leftward, rightward, and in a combined direction by its operation, has a substantially disk shape as shown in FIGS. 13 to 16. It has an angle adjustment mechanism 2 at the rear.
In addition to being equipped with a ball joint 26 that cooperates with 2,
This is similar to FIG. 1.

This rearview mirror is also similar to the rearview mirror in Figure 1.
By simply pressing the mirror holder 4 against the holder plate 23, the mirror holder 4 can be tightly assembled to the holder plate 23 both in the front-rear direction and in the circumferential direction.

In addition, in the above embodiment, the protrusion 7, the flange 8, the fitting part 16
and the engaging portions 17 were provided at four locations each, but the present invention is not limited to this, and the shape of the peripheral edge of the holder plate (3.23) and the shape of the opening 12 corresponding thereto are both circular, but the present invention is not limited to this. If the engaging portions 17, 17° 17.17 are formed to extend inward of the opening 12, the mirror holder 4 can be attached to the holder plates 3, 2.
When pressed against the holder plate 3.2, each retaining portion 17 is pressed against the holder plate 3.2.
3 itself, the flange 8. 8.
8. 8 can be omitted, and it goes without saying that this invention can be modified in various ways to the above embodiment.

Since this invention is constructed as described above, by simply pressing the mirror holder holding the mirror against the holder plate of the angle adjustment mechanism, the front surface of the fitting part is locked to the bent part of the protrusion, and the retention is achieved. Since the rear surface of the retaining part contacts the holder plate, the mirror holder is tightly assembled to the holder plate in the front-rear direction, and the end of the retaining part contacts the end of the bent part of the protrusion, so the mirror holder is attached to the holder plate. Therefore, the mirror holder can be tightly assembled to the holder plate both in the front-to-back direction and in the circumferential direction, and the angle adjustment mechanism can be assembled separately from the mirror, making its assembly easier. It simplifies the work and improves efficiency, and also enables efficient assembly work, such as assembling a large number of angle adjustment mechanisms of the same standard and assembling mirrors of various standards to these to produce a product. It has excellent effects such as being able to perform
