JPS58105105A - Rearview mirror distance confirmation mark of vehicle - Google Patents

Abstract

PURPOSE:To confirm the distance to a vehicle which approaches from behind roughly during drive when its reflected image becomes large as a line frame mark, by printing the line frame of some size on a rearview mirror with a convex surface. CONSTITUTION:Large and small confirmation marks 1 and 2 for line frames are used in combination. Those marks are used to confirm reflected images of following vehicles at short and long distances on left and right sides. The sizes depend upon the size of the surface of a rearview mirror 5.

Description

[Detailed Description of the Invention] This invention relates to rear view mirrors for automobiles and motorcycles, and is capable of confirming the distance when the shadow of a car approaching from the left and right rear is captured on the rear view mirror (5). Display line frame (
1) (This refers to 2+.

The conventional rear view mirror (5) is simply approached from the left and right rear.
Its only function is to check for cars, and distances are determined by a sixth sense. This judgment is developed and acquired over many years of driving, and therefore, it can be somewhat dangerous for beginners when changing direction or when they cannot see in the rearview mirror.

In order to eliminate this drawback, the feature of the conventional rear view mirror (5) that reduces the size of the curved surface can be used to create a frame of a certain size (fl).
(2+ is displayed by printing it on the rear view mirror (5), and the shadow of the car approaching from the left and right rear while driving is shown in the frame (1) f21
The time when it reaches the size of a mark [Figure 3] (1), the time (
2) allows you to check the approximate distance.

(The method for confirming the distance is that the driver memorizes a table calculated for each vehicle type.) The advantage of this is that it allows you to calculate the approximate distance of vehicles approaching from the left and right rear. For example, when changing course when overtaking or cutting in, if you change course at a distance within the size of the reel (2) [Figure 3] that will not interfere with other vehicles behind you. , you will be responsible for driving all the time.

Also, while looking ahead, I noticed the shadows of vehicles approaching from the left and right rear.
By knowing the approximate distance, you will be able to obtain information to make appropriate decisions for better and safer driving.

Below, we will explain these features along with their drawings (a)
Wire bar confirmation mark (1) (2+ means large (1) and small (2)
), and it is constructed by combining these.

The large mark (1) is a line bar mark f1) +2) used to confirm the shadow of a vehicle that is close to the left and right rear distances, and the small mark (2) is a wire bar mark f1) +2) that is used to confirm the shadow of a vehicle that is far away from the left and right rear.

(b) The size of the wire rods (1) and (2) differs depending on the size of the rear view mirror (5) of each car model, but the small (2) mark indicates the same distance between the left and right rear vehicle shadows. A wire rod of the size of the shadow of a vehicle approaching within 30 meters from 2 meters [Figure 3]
2).

The large (1) mark indicates the size of the vehicle shadow approaching within 6 meters to 15 meters between the left and right rear vehicle shadows [3
This is the wire rod (1) in the figure.

The line bar in (1) is also the distance from the rearview mirror at which the shadow of the vehicle disappears.

(c) The wire rods (1) and (2) were combined so that the center point (3) of the wire rods (1) and (2) were misaligned so that the left and right diagonally backward cars were captured in a straight line. This combination is different from the wire rod on the left (Figure 2) and the wire rod on the right (Figure 1).

(d) This wire bar mark is generally composed of a wire bar mark (11 (2+) printed on synthetic resin transparent paper (4) and placed in close contact with the rearview mirror (5), or a rear view mirror (5). At the manufacturing stage of the mirror (5), a wire rod (11 (2+) is embedded using piano wire or a similar wire, or it is printed directly on the front and back surfaces.

Confirmation marks constituting the features explained in (a), (b), (c), and (d) above +1) (2) are displayed on the rear view mirror (5), so that the shadow of a vehicle approaching from the left and right rear is a straight line. Bar (1) (2+
The time (1) and the time (
In 2), the distance can be found by memorizing the attached calculation table for each vehicle type.

[Brief explanation of the drawing]

Figure 1 shows the wire rod on the right side. Figure 2 shows the wire rod on the left side. Figure 3 shows the wire rod used for the rear view mirror (1). The wire rod is close to the rear (2).・

Claims (4)

[Claims] (1) Confirmation mark frame (11 (2+) is a combination of circular, square, triangular, rectangular, and polygonal sizes from 1 to -L. (2) Reel frames (1) and (2) are printed on synthetic resin transparent paper. (3) Reel fl) (2+ is printed directly on the front and back sides of the rear view mirror. (4) At the rear view mirror manufacturing stage, use piano wire or wire to create a frame (
