Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door mirror provided in an automobile.

Generally, fender mirrors or door mirrors are known as rearview mirrors provided on the outside of automobiles, and in recent years, many cars have been equipped with door mirrors.

Unlike fender mirrors, this door mirror is attached to the outside of the door where the width of the car body is widest, so the mirror body 1 protrudes from the outermost side of the car body by a dimension Q, as shown in Figure 1. There is. If it protrudes like this, there is a risk of collision with an external object while the vehicle is running or stopped. In order to reduce the impact and reduce damage to external objects and the door mirror itself, a shock absorbing mechanism f side door mirror has been put into practical use, in which the mirror body 1 of the door mirror is made to tilt in the event of a collision.

This door mirror with a shock absorbing mechanism has a structure as shown in FIG. 2, for example. That is, reference numeral 2 denotes a mirror base fixed to a door of an automobile, and a mirror main body 1 is attached to this mirror base 2 via a hinge member 3 so as to be tiltable both forward and backward. The mirror body 1 has a mirror 4 fixed to a mirror body 5, and this mirror stay 5.
is movably supported relative to the mirror housing 6, and an electric drive unit 7 for moving the mirror body 5 to an appropriate inclination by remote control is built into the mirror housing 6. 7a is the same electric wire protection tube.

On the other hand, the hinge member 3 has one end that is rotatably attached to the mirror base 2 with a rear shaft 3a, and the other free end that is connected to the front shaft 3b of the mirror housing of the mirror body 1. 6
is rotatably attached.

As a result, the mirror main body 1 rotates in the direction of the arrow about the rear shaft 3a, that is, tilts backward, and rotates in the direction of the arrow B, centering on the front shaft 3b, that is, tilts forward. It has become.

A tension spring is installed between the mirror body 1 and the mirror base 2 so that the mirror body 1 supported in this manner is brought into contact with the mirror base 2 and maintained in a usage position protruding to the side of the vehicle body as shown in the figure. 8 is stretched so as to bias the mirror main body 1 in the direction of arrow C. Specifically, this tension spring 8 is rotatably attached to the mirror base 2 with a pin 9. One end is attached to the cut link IO, and the other end is attached to the mirror housing 6. It is being

In the door mirror with a shock absorbing mechanism configured in this way, when the mirror body 1 receives an external force in the direction of the arrow, the hinge member 3 rotates in the direction of the arrow around the rear shaft 3a, and the mirror body 1 is rotated in the direction of the arrow.
The hinge member 3 and the hinge member 3 tilt backward as shown by arrow A in FIG. 3 against the biasing force of the tension spring 8, and the impact of the external force is alleviated. When the external force is removed,
Of course, the tensile force of the tension spring 8 causes the mirror body 1 to return to its original position as shown in FIG.

Further, when the mirror main body 1 receives an external force in the direction of arrow F, the hinge member 3 rotates in the direction of arrow B around the front shaft 3b,
The mirror main body 1 is tilted forward as shown by arrow B against the biasing force of the tension spring 8, and the impact of external force is alleviated.

However, although the mirror body of such conventional door mirrors is designed to tilt to reduce impact, it is not possible to maintain the tilted position, so transportation by boat or I/Rator is not possible. In some cases, there is a problem in that the mirror body 1 protrudes laterally and occupies extra space. As a countermeasure against this problem, some conventional methods have been to ship the vehicle with the door mirrors not attached or removed, and then attach the door mirrors after landing. However, compared to installing door mirrors at an assembly factory, the work of installing door mirrors at the destination requires more time due to equipment and procedures, and there is a risk of defects, so it is not sufficient. Ta. On the other hand, in addition to the above-mentioned transportation, when entering a parking lot within the department, especially when entering a multi-storey parking lot, etc.
You may not be able to park because the Mira body 1 protruding to the side gets in the way.

It was extremely inconvenient.

This invention was made in view of the conventional situation, and it is equipped with a buffer function, allows the tilted posture of the main body of the mirror to be maintained with a small number of parts, and also makes it possible to maintain the tilted posture of the mirror body with a small number of parts. The object of the present invention is to provide a door mirror for an automobile that can be operated quickly and easily.

In order to achieve this object, the automobile door mirror of the present invention has a mirror base fixed to the door, and the mirror body is rotatably attached to the mirror base via a hinge member so as to be tilted toward the vehicle body (=J A tension spring is installed between the mirror base and the mirror body, which biases the mirror body so that it is always protruding to the side of the vehicle, and further tensions the mirror body. A locking mechanism is provided to hold the mirror body in a tilted position against the force of the spring, and the locking mechanism has a mirror stay rotatably attached to the mirror base.

The distal end of the mirror stay is formed with a locking part that locks with the locked part of the hinge member when the mirror body is in the tilted position to maintain the tilted position. The present invention is characterized in that a release means is provided for disengaging the locking portion from the locked portion and returning the mirror main body to the usage position by the biasing force of the tension spring.

The present invention will be explained below based on the drawings. In this description, parts that are the same or equivalent to the conventional parts or part H will be designated by the same reference numerals, and redundant description will be omitted.

4 to 8 are diagrams showing a first embodiment of the present invention.

First, to explain the structure, in the automobile door mirror of this embodiment, the mirror body 1 is rotated to the mirror base 2 fixed to the door via a hinge member 3 so as to tilt forward and backward toward the vehicle body. A tension spring 8 is tensioned between the mirror main body 1 and the mirror base 2, and a locking mechanism 15 is further provided to maintain the tilted posture of the mirror main body 1.

One side of the hinge member 3 is located at the rear end of the mirror base 2 of the vehicle as shown in FIG.

The mirror housing 6 of the mirror main body 1 is rotatably mounted on the other side by a front shaft 3b, which is not visible in FIG. This makes it possible to tilt the mirror body 1 forward and backward.

As shown in FIG. 4, the tension springs 8 are almost completely built into the mirror main body 1, and two tension springs 8 are disposed substantially parallel to each other in the upper and lower parts. One end 8a of these tension springs 8 is hooked on the tip of the link IO, and the other end (not shown) is attached to a bracket 1 (not shown) provided in the mirror body 1. There are 4 tensions.

On the other hand, the locking mechanism 15 includes a mirror stay 16 and a release means I7.

The mirror stay 16 has the shape of a curved elongated plate, is rotatably attached to the base end of the mirror base 2 by a shaft 18, and biased in the direction of arrow 1-1 by a spring 19. In addition, this mirror stay 16 has
Curved guide hole 16. l is formed in the longitudinal direction,
This guide hole 16a is bent at the tip of the mirror stay 16. This bent part A is the locking part 16b.
It is said that A locking pin 3c, which is a locked portion formed in the hinge member 3, is inserted into this guide hole 16a. The locking portion 1 between the locking pin 3c and the guide hole L6a
6b is set such that when the mirror main body 1 is tilted, the locking pin 3c enters into the locking portion IGb and locks. In addition, the spring 19 mentioned in niJ
acts to cause the locking pin 3c to enter the locking portion 16b.

Further, the release means 17 includes the aforementioned locking pin 3c and the locking portion I.
It is for releasing the lock from Gb, and consists of a release rod 20 and a lever part 21. The release iron 20 has a crank shape and is rotatably attached to the mirror base 2, with one end 20a abutting against the side of the mirror stay 16, and the other end 20b protruding from the bottom of the mirror stay 2. There is. A lever part 21 is fixed to the other end 20b, and the lever part 21 is urged in the direction of arrow 1 by a spring 22, so that the one end 20a of the release iron 20 is always attached to the side of the mirror stay 16. They are designed to touch each other.

The operation of the door mirror having such a configuration will be explained. When the door mirror is used while the vehicle is running, the guide hole 1 of the mirror stay 16 should be opened as shown in Fig. 5.
The locking pin 3c of the hinge member 3 is positioned on the base end side of the hinge member 6a, and the mirror body 1 is pulled by the force of the tension spring 8 and protrudes toward the side of the vehicle as shown by the solid line in FIG. The usage position is as shown. Here, even if the vehicle vibrates, the tension spring 8
The mirror main body 1 does not blur due to the tensile force, and rearward visibility can be sufficiently performed.

When a collision occurs with an external object while driving, the mirror body 1 resists the biasing force of the tension spring 8 and tilts backward or tilts around the rear shaft 3a or the front shaft 13b, as described in the conventional example. By leaning forward as shown in the figure, the impact is softened and damage to the mirror body 1 or external objects is reduced.

On the other hand, in order to park in a place where the parking space is narrow, such as a multi-story parking lot, the following procedure is performed.

That is, the tension link 8 is applied to the mirror body 1 by hand.
Rotate it backwards against the urging force of. As the hinge member 3 rotates rearward around the rear shaft 3a,
The locking pin 3C moves through the guide hole 16a of the mirror stay 16 toward the tip side. When the mirror main body 1 is tilted backwards as shown in FIG. As the locking pin 3C rotates, the locking pin 3C enters and locks into the locking portion 16b of the guide hole 1 (ia).

Even if you release your hand in this state, the mirror stay 16 becomes a protruding support rod due to this adjustment, and as shown in FIG. held against. In this way, by folding the Mira main body 1 as shown by the two-dot chain line in FIG. 8, it becomes possible to park the vehicle even in a place with a narrow parking space, such as a V1 multi-story parking lot.

When the car is taken out of the parking lot as described in 2 and is driven, the release means 1 is used to move the Mira body 1 from the backward tilted position.
9 to return to the working position. That is, the lever portion 21 is held and rotated in the direction of the arrow 1 in FIG. By this rotation, the mirror stay 16 is pressed by the one end 20a of the release rod 20, and is slightly rotated against the biasing force of the spring 19. This causes the locking pin 3C to move into the guide hole 1.
6a is released from the locking portion 16b, and the mirror main body 1 can be rotated.

The mirror main body 1 is rotated from the backward tilted position to return to its original position by the force of the tension spring 8, and assumes the usage position as shown in FIG. This will allow you to see backwards. Note that since the release rod 20 is always in contact with the mirror stay 16 due to the spring 22, the release rod 20 and the lever part 21 will not get stuck.

In this way, the mirror main body 1 can be held in the tilted position and returned to the use position by the simple operation of rotating the mirror main body 1 and the lever part 21. Therefore, it is not necessary to take much effort to operate the door mirrors, and the vehicle can be easily parked in and departed from a narrow space, thereby improving the usability of the vehicle. Of course, even when transporting, if you fold it up, you can reduce the space it occupies in a single car, reduce transport costs, and eliminate the work of installing door mirrors on site, making it very easy to transport. It will be done.

Further, since the locking mechanism 15 has a simple structure consisting of the mirror stay 16 and the release means 17, a narrow space is sufficient for installation, and the locking mechanism 15 can be easily installed without increasing the size of the door mirror.

9 to 12 show a second embodiment of the invention.

In the automobile door mirror of this embodiment, a locking mechanism 25 is different from the locking mechanism 15 of the first embodiment.

The lock mechanism 25 of this embodiment consists of a mirror stay 26 and a release means z7. The mirror stay 26 is
It has an elongated plate shape, and its base end is rotatably attached to the mirror base 2 by a shaft 28 or the like, and is biased in the direction of arrow 1 by a spring 29.

This mirror stay 26 is provided with a locking portion 26a formed by cutting out at a substantially right angle at the tip thereof.

This locking portion 26a is configured to lock with the locking pin 3C of the hinge member 3 when the mirror main body 1 is in a backward tilted position.

On the other hand, the release means 27 has substantially the same configuration as the first embodiment, and the difference is that one end 30a of the release rod 30 is located on the opposite side of the mirror stay 26 from the first embodiment. The reason is that it is set so that it is always in contact with the side part.

1 when driving a vehicle (if you are using mirrors,
As shown in FIG. 10, the locking pin 3c of the hinge member 3 is in contact with the proximal side of the mirror stay 26, and is arched by the tension spring 8, so that the mirror body 1 is not used. It is a posture.

In the event of a collision with an external object, the first embodiment tilts backward or forward as shown in FIG. 12 around the rear shaft 3a or front shaft 3b to soften the impact and reduce the impact. Damage to the main body 1 or external objects is reduced.

On the other hand, in order to park in a narrow parking space such as a multi-story parking lot, the Mira main body 1 is manually rotated backward against the force of the tension spring 8. Hinge member 3
As the locking pin 3c rotates rearward around the rear shaft 3a, the locking pin 3c holds the side of the mirror stay 26 on the tip side 7\
Move towards it.

When the mirror main body 1 reaches the 11th backward tilting position as shown, the locking pin 3c reaches the tip of the mirror stay 26, and the mirror stay is fixed by the biasing force of the sub link 29 in the direction of the arrow ■. 26 is rotated, the locking pin 3c enters into the locking portion 26a and is locked. In this state, the mirror stay 26 serves as a protruding support rod to maintain the rearward tilted posture of the mirror body 1.

To return the mirror main body l from the backward tilted position to the operating position, 1 rotate a part of the lever (not shown) and release the lever 3.
By pressing and rotating the mirror stay 26 at 0, the locking state between the locking pin 3c and the locking portion 26a is released. Then, the mirror main body 1 is rotated by the force of the tension spring 8 and returned to the usage position shown in FIG. 10.

Other main growth and operations are the same as those in the first embodiment, so explanations will be omitted.

The release means according to the present invention is comprised of the release rod 20, 30 and the lever part 21 in each of the above embodiments, but is not limited thereto, and may have various configurations. In other words, since this release means releases the locked state between the mirror stay and the hinge member,
-As an example, one possibility is to extend the rod from inside the vehicle to reach the mirror stay, and then operate this rod from inside the vehicle to rotate the mirror stay and release the lock. It will be done.

As explained above, according to the present invention, a locking mechanism that is easily installed without increasing the size of the door mirror not only provides an impact function but also maintains the tilted posture of the mirror body. Moreover, it has the effect of being able to be quickly and easily operated into the tilting position and the use position.
