Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mirror device used in trucks, buses, and other automobiles.

In the case of large trucks and other vehicles in which the driver's seat is in a high position, there is a blind area on the side opposite to the driver, usually on the left side, even though the vehicle has a main rearview mirror and an under mirror outside the vehicle. Therefore, if there are people or bicycles within the blind area, the driver will not be able to see them, and accidents involving people or bicycles will occur due to the difference between the rear wheels when turning left, which has become a social problem. ing.

FIG. 1 is a front view of a part of a conventional truck, and FIG. 2 is a side view of the same.

As shown in these figures, in trucks, etc., the main outside mirror b is attached to the stay a that protrudes into the interior.
and an under mirror C are installed, but the field of view with the main outside mirror B is B shown in Figure 3, and the field of view with the under mirror C is C, which is required for safety in Area Y notified by the Ministry of Transport. On the other hand, there is a blind area X.

Furthermore, since the under mirror C has a small radius of curvature of 100 to 120 R, the image produced by the under mirror C is small, and the distortion of the image is large, resulting in poor visibility.

The image is reversed, and the exact positional relationship is also good.

In view of the above circumstances, the inventors of the present invention have developed a blind area visualization device for automobiles that eliminates the blind area, provides a wide field of view, enlarges the image, and provides an erect image, making it easier to understand the positional relationship. proposed.

(Refer to Japanese Utility Model Application No. 55-157201) As shown in Figures 4 to 6, this device is installed at the top near the corner opposite to the driver's seat, and covers the front and front sides of the vehicle body. An under mirror 1 made of a convex mirror for visual field, and eyeglasses 2 that reflect the image of the under mirror 1 in the direction of the driver so that the driver can see the image.
Therefore, a cover 3 having a size that prevents unnecessary light from entering the eyeglasses 2 when viewing the eyeglasses in the eye zone is disposed on the under mirror 1.

In this way, as shown in FIG. 6, it is possible to obtain a field of view Z that was previously a blind area, and the image obtained through the under mirror 1 and the eyeglasses 2 is erect. This has the effect of making it easier to understand the positional relationship.

(In the figure, EP indicates the driver's eye point.) The cover 3 is used to prevent dazzling light from entering the driver and to prevent obstacles such as raindrops from adhering to the mirror surface. However, in reality, it is impossible to avoid raindrops etc. from adhering to the mirror surface, and
I learned that it is difficult to remove raindrops etc. once they have adhered to the mirror surface.

That is, as shown schematically in Fig. 7, the airflow accompanying the running of the car becomes a vortex-like turbulent flow at the front and rear parts of the mirror surface 1', especially at the rear part, as indicated by the arrows in the same figure, and the cleaning function is not achieved. On the contrary, the turbulent air flow at the rear hits the mirror surface 1', and rainwater carried along with the air flow adheres to the mirror surface 1', resulting in reduced visibility.

The present invention not only improves the problems of the prior art as described above and allows the user to see areas that were previously blind areas, but also enables the user to see even if raindrops etc. adhere to the mirror surface. , it is an object of the present invention to provide an automobile mirror device that can improve visibility by forcibly removing this.

In order to achieve the above object, the present invention provides an opening in the mirror device shown in FIGS. It is characterized by being designed to blow rainwater etc. backwards.

Under mirror 1 and cover 3 used in the device of the present invention
Specific examples of this are shown in FIGS. 8 and 9.

That is, as shown in FIG. 8 which is a longitudinal side view and FIG. 9 which is viewed from below, the cover 3 of this example includes a substantially horizontal flat base 32 and an overhanging portion 33 that extends diagonally downward from the base 32. This projecting portion 33 is located at the front (3 in the figure).
3') and both sides (indicated by 33'' and 33'' in the figure), and are not formed in the rear part, so that the base 32 only extends in the horizontal direction.

Therefore, as a result, the rear portion of the cover 3 forms an opening 31.

In the figure, reference numeral 4 denotes a bracket for attaching the mirror to the side of the vehicle body, to which the cover 3 is fixed with rivets or the like.

A body 5 is fixed to the lower surface of the cover 3 by welding or the like, and the periphery of the under mirror 1 is gripped and attached to the outer periphery of the body 5.

Further, this peripheral gripping portion has a ring 6 interposed therebetween.

A ring 7 is also attached to the entire circumference of the cover 3.

Since the mirror device according to the present invention is configured as described above, it is possible to eliminate blind areas and provide a wide field of vision, but it also prevents raindrops and other visual obstacles from adhering to the under mirror. Even if it does get stuck, it can be removed by the airflow while driving, allowing you to always see clear images.

That is, when the vehicle is stopped or operating at low speed, the cover itself acts like an umbrella to prevent raindrops from adhering to the mirror surface.

Furthermore, since the opening 31 is provided behind the mirror surface of the cover 3, the airflow flowing through the opening 31 becomes a flow that wipes away the mirror surface as shown in Fig. 8, and raindrops etc. adhering to the mirror surface are removed. Even if there is such a foreign object, it will be moved to the rear of the mirror surface by the airflow generated by the vehicle, and eventually it can be blown backwards and removed, ensuring good visibility at all times. can do.

Figures 10 to 13 show separate covers.

The cover 3a shown in FIG. 10 has an overhanging portion 33a formed around the entire circumference from a substantially circular base 32a to give the entire shape a substantially flat truncated cone shape, and a window-shaped opening cut out only in the rear part of the overhanging portion 33a. 31a is provided.

The cover 3b in FIG. 11 has almost the same shape as the example in FIG. 10, but has a plurality of independently cut out (four in the figure) divided windows 31b, which are used as openings. It is.

The cover 30 in the example shown in FIG. 12 has the lower edges 34a and 34b left as a result of making the opening into a window shape in the examples shown in FIGS. 10 and 11, whereas the cover 30 in the example shown in FIG. The cut-out portion 31c is used as an opening.

The one shown in FIG. 13 is similar to that shown in FIGS. 8 and 9, and only the mounting direction of the bracket 4 is different.

In addition, in FIGS. 10 to 12, 4a, 4b, and 4c indicate brackets.

It is obvious that the examples shown in FIGS. 10 to 13 have the same effects as the embodiments shown in FIGS. 8 and 9 described above.

As mentioned above, the mirror device of the present invention is installed in the upper part of the driver's cab of a car near the corner on the opposite side from the driver's seat, and consists of a convex mirror that provides a field of vision to the front and front sides of the car body. In an automobile mirror device comprising a mirror and pair of glasses that reflect an image of the under mirror and make the image visible to a driver, a cover having a periphery of a protruding portion that covers the mirror is disposed on the under mirror. In addition, the cover is characterized in that an opening is provided on the rear side of the mirror surface, and the foreign matter adhering to the mirror surface is discharged rearward by the airflow flowing through the opening. In addition to significantly improving driving safety by eliminating all areas of friction, it also prevents foreign objects such as raindrops and snow from adhering to the mirror surface, which can impede visibility.
Even if these foreign substances adhere to the vehicle, they can be cleaned and removed by the airflow during the vehicle, which is extremely beneficial in practice.
