Abstract

PURPOSE:To see enable the driver to see the side part and the head way direction of the vehicle by arranging the prism at the side mirror of the vehicle. CONSTITUTION:Since the bottom part of a triangular prism 1 is projected part sphere shaped, the light made incident in the head way direction of the vehicle, namely, in the A direction, is reflected at a projected part sphere 2 of the triangular prism 1, the light is reflected in the B direction and the light arrives at the driver of the vehicle. At such a time, since the bottom part of the triangular prism 1 is a projected part sphere, the substance in the A direction is reflected at the projected part sphere 2 and reflected in the B direction, the substance comes to be small and arrives at the eye of the driver. For the size, when the size of the curve of the projected part sphere 2 is made large, the substance in the A direction is seen small at the time of reflection, and therefore, the size of the curve is freely selected, and can be made into the size which the driver can easily see.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a front confirmation mirror or a front/rear confirmation mirror of a vehicle, particularly a side mirror for a four-wheeled vehicle.

Conventional side mirrors were generally located on both sides of the vehicle to allow the driver's seat to see both sides and rear of the vehicle.

In this case, both sides of the front wheels of the vehicle are out of sight, and when turning left, if there is an obstacle or a motorcycle, etc. is located near the front wheels, they are out of sight and may come into contact with the vehicle. There were many concerns. Also, with conventional spherical mirrors, the state immediately in front of the engine appears deformed, making it appear different from the actual state.

The present invention can solve the above-mentioned problems, is inexpensive, has a simple structure, can be made compact, can be constructed without major changes to the structure of conventional side mirrors, and can provide the desired visibility for parents. The present invention provides a device that can be viewed accurately, without deformation, and in its current state.

Hereinafter, the present invention will be explained in detail according to the drawings. First of all,
Figures 1 and 2 show a side mirror using a triangular prism 1. The bottom of the triangular prism is a convex spherical surface 2, and this part emits radiation. For reflection, a black reflecting surface 3 having a convex spherical surface 10 in the center is disposed on the back surface of the convex spherical surface 2. The reflective surface 3 is bonded to the convex spherical surface 2 of the triangular prism 1. Moreover, instead of adhesive, snap fastening, press fitting, or screw fastening may be used.

4F'! 5.6 with triangular side mirror case
is a hook part that is attached to a door or fender. A fixing plate 7 is made of a metal plate or resin and has a concave spherical surface 9 in the center, and is screwed to the case 4 with four screws 8.

A large hole 11 is provided in the convex spherical surface 10 of the reflective surface B so that the convex spherical surface 10 of the reflective surface B can rotate relative to the concave spherical surface 9 of the case 4 in a spherical relationship. 12, the convex spherical surface 10 and the concave spherical surface 9 can be moved relative to each other by screws. The case 4 has an opening 16 when viewed in the direction of arrow A, through which the front part of the vehicle can be seen.

The operation of the first embodiment will be explained with reference to FIGS. 1 and 2 above.
First, since the bottom of the triangular prism 1 has a convex spherical shape, light incident from the front of the vehicle, that is, from the entrance direction, is reflected by the convex spherical surface 2 of the triangular prism 1, and the light is reflected in the direction B. The light reaches the driver of the vehicle. At this time, since the bottom of the triangular prism 1 is a convex spherical surface, when an object in the A direction is reflected by the convex spherical surface 2, it becomes smaller when reflected in the B direction and reaches the driver's eyes. Also, if the size of the curvature of the convex spherical surface 2 is increased, objects in the A direction will appear smaller when reflected, so the size of the curvature can be freely selected to make it easy for the driver to see. is possible.

In addition, since the triangular prism 1 is rotatable in a quadratic limit between the convex spherical surface 10 and the concave spherical surface 9, when the field of view in the input direction reaches the driver, the prism 1 can be rotated freely by hand to the secondary limit. It can be rotated within a limited range to bring it to the optimal position. Moreover, the triangular prism 1 can be operated not only by hand but also by electric operation such as a remote control mirror.

Next, the second embodiment will be explained with reference to FIGS. 6 and 4.
The second embodiment differs from the first embodiment in that the bottom of the triangular prism 1 is a concave spherical surface 14. The other configurations are the same as those in the first embodiment, and will therefore be omitted. Incidentally, FIG. 4 is a view seen from the direction of arrow A in FIG. 6.

Here, to explain the operation of the second embodiment, the triangular prism 1
Since the bottom of the spherical concave surface 14 is a concave spherical surface 14, when light enters an object on the side or front of the vehicle from the incident direction, it is reflected by the triangular prism 10 and the four spherical surfaces 14 in the B direction, and the driver's It reaches the eyes. At this time, when the light is reflected by the four-part spherical surface 14, the size of the object in the direction A appears larger. Furthermore, the size of the object that enters the driver can be freely changed depending on the degree of curvature of the spherical surface 14 of the concave portion. That is, the four-part sphere 1
If the curvature of 4 is large, the object entering the driver will appear large. Furthermore, as in the first embodiment, the triangular prism 1 rotates in a quadratic limited manner, so that the triangular prism 1 rotates in a two-dimensional limited manner. It is designed to be positioned freely within the driver's field of vision.

Next, the third example? This will be explained with reference to FIGS. 5 and 6. 6th
The figure is a view seen from arrow A in FIG. The sixth embodiment differs from the first embodiment in that the triangular prism 1
has a flat surface 15 at its bottom.

Hereinafter, the operation of the sixth embodiment will be explained with reference to the drawings. First, light enters an object on the side or front side of the vehicle from the direction of arrow A, and is further reflected by the flat surface 15. In this case, the incident angle θ1
The reflection angle e2 is the same as 1 and 6, and the magnitude of +θ2 is the angle θ of the triangular part of the triangular prism 1. determined by. Therefore, not only can the triangular prism 1 itself be rotated in a quadratic limit, but also the triangular prism 10 can be rotated by an angle θ. By freely changing the field of view, the driver can easily see what is in front of the vehicle. In addition, the triangular prism 10 angle θ. The selection of the size is the same for the first and second embodiments.

Next, what is the range of visibility depending on the size of the flat part 15 of the sixth embodiment? It can be changed. Also, this idea applies to the first and second
The same applies to the embodiments.

Next, referring to FIG. 7, the configuration of the fourth embodiment will be explained. 7th
In the figure, the side and rear portions of the vehicle are viewed through a spherical mirror 16, and the side and front portions of the vehicle are viewed through the triangular prism 1 shown in FIGS. 1 and 2. That is, it is a composite type side mirror in which a 1 ft triangular prism is arranged in one side mirror case 4 for forward confirmation, and a spherical mirror 16 is used for rear confirmation. Note that the spherical mirror 16 and the triangular prism 1 may not be housed in the case 4, but may be housed independently. Furthermore, the triangular prism 1 for checking the front can have a larger rotation range so that both the front and rear of the vehicle can be seen. In this case, it is easier to operate the triangular prism 1 not only by rotating it by hand but also by using an electric remote control. Further, FIG. 8 is a central vertical sectional view showing the mounting relationship and rotational relationship of the spherical mirror 16 of FIG. 7.

Reference numeral 7 denotes a fixing plate made of a metal plate or resin, which is usually screwed to the case 4 through a hole 17.

Furthermore, a concave spherical surface 9 is provided at the center of the fixing plate 7. 3
is a reflective surface, which is usually black in color, and is bonded or screwed to the spherical mirror 16. A convex spherical surface 10 is provided at the center of the reflective surface B, and corresponds to the four-part spherical surface 9. Further, a large hole 11 is provided in the convex spherical surface 10, and a spherical mirror 16 can rotate within the range of this hole. Also, 12 is a screw that connects the fixing plate 7 and the reflective surface 6? Fixed. 17 is a guide for the reflective surface 6. 18 is the nut of the screw 12.

In the configuration shown in FIG. 7 above, objects on the sides and rear of the vehicle are exposed to light that enters from the incident direction, is reflected by the spherical mirror 16, and exits in the B direction to reach the driver's eyes. , for an object on the side or front of the vehicle, light enters from direction A and the convex spherical surface 10
The light is reflected by the light, exits in direction B, and reaches the driver's eyes, making objects in front appear smaller. This will give you a wider field of vision both in front and behind you.

Next, referring to FIG. 9, the configuration of the fifth embodiment will be explained. It is similar to the fourth embodiment shown in FIG. 7, except that the triangular prism 1 has four spherical surfaces 10, making the object appear larger than it actually is It looks like this.

The configuration of the pond is the same as in Figure 7. Therefore, light enters the concave spherical surface 10 from direction A when objects are on the side or in front of the vehicle.
The light is reflected in direction B and reaches the driver's eyes. At this time, the object in the A direction appears larger than it actually is.

Next, referring to FIG. 10, the sixth embodiment will be explained. In contrast to the fourth embodiment shown in FIG.
The only difference is that it is set to 0, and the other configurations are the same. That is, if the bottom of the triangular prism 1 is made flat,
Light enters an object on the side or front of the vehicle from the entrance direction, is reflected by the flat surface 10, and the light exits in the B direction and enters the driver's eyes. At this time, since the bottom part is the flat part 10, an object in the entrance direction enters the driver's eyes with approximately the same size in the B direction. 16 is a spherical mirror that allows you to see the sides and rear of the vehicle.

Next, referring to FIG. 11, the configuration of the seventh embodiment will be explained. In this embodiment, the left triangular prism is arranged as a husband prism that allows viewing the side and front of the vehicle, and the right triangular prism allows viewing directly below the engine compartment of the vehicle. 1 is a triangular prism, and the bottom thereof has a convex spherical surface 10. 17
is another triangular prism, the bottom of which has a convex spherical surface 10. This is a 4 case. The mirrors shown in FIG. 11 are installed at both corners of the engine compartment of a vehicle. That is, light enters an object on the side or front of the vehicle from the entrance direction and is reflected by the convex spherical surface 10 of the triangular prism 1, and the light exits in the B direction and is reflected in the driver's eyes. On the other hand, light enters an object located in front of or directly below the engine compartment of the vehicle from the entrance direction, is reflected by the convex spherical surface 10, and the light exits in the B direction and enters the driver's eyes. In this case, what is the size of the object with the conventional convex spherical surface? Although it was not possible to see the object uniformly, in this embodiment, the size of the object can be seen uniformly, making it extremely easy to see the object.

Next, FIG. 12 is a central cross-section showing the attachment relationship of the triangular prism 1 of each embodiment. 2 has a convex spherical surface of the prism 1, 3 has a black reflective surface, 7 has a concave spherical surface 9 in the center,
Further, at the four corners there is a fixing plate with mounting holes 8 that are screwed to the case 4, 17 is a guide, 12 screws are used to fix the fixing plate 7 and the reflecting surface 6, and there is no play in the four spherical surfaces 9. It has a hole 11, and six reflective surfaces can freely rotate within the range of this hole. Further, the reflective surface 3 is bonded or screwed to the triangular prism 1.

With the above configuration, the triangular prism can freely rotate within the range of the one hole 11. Therefore, the triangular prism can be oriented at any angle.

Although each of the above embodiments shows only triangular prisms, the present invention is not limited to triangular prisms, and triangular prisms may be synthesized as shown in Figure 1. The direction can be changed freely.

Here, to explain the structure and function of triangular prism 1 in Figure 1, prism 1 is a combination of two triangular prisms, and 6 is a reflective surface that is black and is fixed to prism 1 with screws or adhesive. It is being 6 forms a four-part sphere.

The prism 1 can be housed in the case 4 of each embodiment.

With the above configuration, the light entering from A is reflected by the reflective surface 3, and it is also possible to exit from another reflective surface 3 and emit light in the B direction to reach the driver's eyes. In embodiments, conventional mirrors may be mounted on fenders or mounted on doors. Furthermore, it may be placed at the front of the vehicle or at the rear of the vehicle, so that it can be seen by the driver wherever it is placed.

From the above explanation of the structure and operation, it is clear that in the present invention, the conventional convex spherical mirror could not provide visibility to the driver.
Any field of view easily using a triangular prism? It is something that can be seen, especially the side/front of the vehicle or the front/directly below the engine room. Furthermore, with a spherical mirror, the size of the object appears to the driver to be unbalanced in length and width, but with the present invention, the object appears to be in a uniformly compressed and expanded shape that is close to the real thing, making it extremely easy to see the object.

In addition, since it can be obtained with a triangular prism, it can be obtained at a low cost. Furthermore, since it is compact in shape, there are no problems with installation and it has the advantage of being downsized.
