Description

[Detailed description of the invention] The present invention relates to an outside mirror.

2. Description of the Related Art Conventionally, outside mirrors having a large mirror area are known, as shown in FIGS. 1 to 3. This conventional outside mirror 1 is attached to a vehicle body such as a door (not shown) using fixing means such as bolts.

In addition, the seat surface 2 is crimped to the base 3 which is formed to be inclined to correspond to the curvature of the vehicle body, for example, a door outer panel, and the seat surface 2 of this base 3 by a coil-shaped spring 4VC, so that the seat surface 2 is substantially horizontal. It is composed of a protruding mirror body 5. The coil-shaped spring 4 is
In particular, as shown in FIGS. 2 and 3, one end 4a thereof is fixed to a reinforcing plate 6 fixedly installed inside the mirror body 5 with screws 6a, and the other end 4b is rotatable to the base 3 via a pin T. The mirror body 5 is supported by a shaft and stretched horizontally within the mirror body 5. In addition, the side surface 16VC of the base 3 of the mirror body 5, which is formed to be inclined corresponding to the seat surface 2 of the base 3, has a recessed hole 8 in the upper and lower sides. A protrusion 9 is formed to bulge at a portion of the seat surface 2 that faces the recessed hole 8.
are fitted to prevent the mirror body 5 from sliding along the seating surface 2VC of the 15 base 3 toward the ground. Visit,
10 is a mirror body, 11 is a lever for remotely controlling the mirror body 10 from indoors, 12 is a mirror holder that covers the mirror body 10 from the back side, 13 is a bearing protruding from the mirror holder 12, and 2014 is a lever from the reinforcing plate 6. A pivot 15 is protruded and rotatably supported by the bearing 13, and 15 is a lever 1.
1 shows a lever holder that transmits the operating force of 1 to the mirror holder 12. However, in the conventional outside mirror 1 having a large mirror area 25, when a collision load F acts on the mirror body 5 from the horizontal direction,
The vehicle body (not shown) rotates horizontally as shown by the imaginary line in Figure 4.
Rotate until it is almost in line with the

Thereafter, the tension of the spring 4 causes the mirror body 5 to return to the protruding state shown by the solid line in FIG. 4, 30. However, as shown in FIG. 2, since the angle θ between the tension direction T of the spring 4 and the seat surface 2 of the base 3 is inclined,
A component force P that moves upward along the seat surface 2 of the base 3 is always acting on the mirror body 5. 35 Therefore, as shown in FIG. 4, the mirror body 5 rotates and the protrusion 9 and the recess 8
When the engagement state with the mirror body 5 is released, the mirror body 5 moves upward as shown in FIG. 5, and the reinforcing plate 6 and the lever 11 interfere with each other, making it difficult to operate the lever 11. Was.

As a means to solve this problem, the seating surface 2' of the base 3', as shown in FIG.
should be formed vertically so as to be perpendicular to the tension direction T of the spring 4. However, if the seat surface 2/ is formed vertically, the area of the mirror body 1' becomes smaller. In order to replenish this, the mirror body 5' and the mirror surface body 10' must be enlarged and protruded outward, which causes the problem that the center of gravity moves further outward and vibrations are more likely to occur. The problem was that it could not be adopted suddenly.

This invention was devised in view of the current situation, and its purpose is to enable the mirror body to be folded down and to return to its original position smoothly without eccentricity when an external force acts on the mirror body. This is an attempt to provide an outside mirror that moves back to the front.

In order to achieve this object, the present invention has a mirror body protruding through a base fixed to the vehicle body,
The base and the mirror body can be rotated forward or backward when an external force is applied to the mirror body, and
In an outside mirror in which a spring is tensioned and connected so as to move back to the protruding position, the seat surface of the base and the surface of the mirror body pressed against the seat surface by the spring are in the direction in which the spring is pulled. The mirror body 4 on the base side is formed in a diagonal direction.
The mirror body is provided with a holder portion holding a spring to prevent eccentric movement of the mirror body with respect to the base.

Next, the present invention will be explained in detail based on the embodiment shown in FIG. 7 and thereafter.

The same or equivalent portions and parts as in FIGS. 1 to 6 are designated by the same reference numerals, and redundant explanations will be omitted. The outside mirror 100 according to this embodiment is composed of a mirror body 50, a base 30, and a coiled spring 4.

The mirror body 50 is made of die cast material such as plastic or aluminum, and a reinforcing plate 60 is fixed inside the mirror body 50 with screws 6a, and near the base 30 side of this reinforcing plate 60, In particular, as shown in FIG. 9, a holder portion 61 having a substantially J-shaped side surface and holding the spring 4 is integrally formed.

Since the holder portion 61 has a substantially J-shaped cross section, the work of hanging the spring 4 is simplified. Further, the base 30 is fixed to a vehicle body such as a door (not shown) via a bolt or the like, and its seat surface 20 is formed to be inclined in accordance with the curvature of the outer panel of the vehicle body, and A stop flange edge 21 that engages with the bottom end of the mirror body 50 on the base side is protruded from the upper and lower ends of the seat surface 20.
A protrusion 9 is formed in the lower part of the soil, and the protrusion 9 is connected to a concave hole 8 bored in the base side surface 16 of the mirror body 5, which is inclined to correspond to the seat surface 20 of the base 30. The mirror body 50 works together with the stopper edge 21 to restrict upward sliding movement of the mirror body 50 along the seat surface 20 of the base 30 under normal conditions.

The coiled spring 4 has one end 4a connected to a reinforcing plate 60.
The other end 4b is rotatably supported on the base 30 via a pin 7, and is stretched horizontally within the mirror body 50 to press the mirror body 50 to the base 30.

That is, the mirror body 50 has an angle θ between the tension direction T of the coiled spring 4 and the seat surface 20 of the pace 30.
is pressed to the seat surface 20 of the base 30 in a non-perpendicular state. Therefore, if the collision load F acts on the mirror body 50 as shown in FIG.
0 horizontally rotates as shown by the imaginary line in FIG. 8, and then, due to the tension of the coiled spring 4, the mirror body 50 returns to the protruding state shown by the solid line in FIG. At this time, as described above, since the tensile direction T of the coiled spring 4 and the seat surface 20 of the base 30 are inclined, the mirror body 50 has an upward movement along the seat surface 20 of the base 30. However, since the holder part 61 engages with the coiled spring 4 at the same time, the component force P is canceled out by the engagement between the holder part 61 and the coiled spring 4, and the mirror Eccentric movement of the body 50 is restricted. In the above embodiment, the holder part 61 is arranged on the base side of the reinforcing plate 60 because the offset position of the coiled spring 4 with respect to the component force P is close to the base side end of the coiled spring 4. This is because there are only a few.
Furthermore, even if the seat surface 20 and the tension direction T of the coiled spring 4 are perpendicular to each other, this is included in the present invention since it may have an effect depending on the direction of the impact load. Further, the spring 4 is not limited to a coil shape, but may be S-shaped or the like. According to the present invention, the mirror body rotates when an external force is applied to the mirror body, and the upward eccentric movement force of the mirror body can be offset by the engagement of the holder portion and the coiled spring. The mirror body can be smoothly returned to its original position.

Furthermore, in the above embodiment, the stopper edges 21 are provided protrudingly at the upper and lower ends of the seat surface 20 of the base 30, and the stopper edges 21
1 engages with the lower end of the base side surface 16 of the mirror body 50, so that eccentric movement when the mirror body 50 returns to its original position can be more reliably regulated.
