PURPOSE:To enable the operation of a mirror housing handily and quickly not resisting against a spring force of a tension spring by interposing a zigzaged spring compressed between the neutral plate and the mirror base of a door mirror. CONSTITUTION:A control lever 29 is lifted up to pull a wire 25 against a spring force of a compressed spring 23 so that the free end of the neutral plate 16 is held abbuting on a base plate 3. At this position, a mirror housing 6 housing a mirror 9 is upright at the using position thereof. Under such a condition, when the front of a door mirror 4 hits an outside object under running, a hinge 10 receiving a force F turns backward on a rear shaft 12. When receiving an outside force on the rear face thereof under backward runing, the door mirror 4 turns forward against a spring force of a tension spring 14 centering a front shaft 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door mirror for an automobile that is attached to the outside of a front door.As shown in FIG. There is a type in which a mirror base 3.3 is fixed to the outside of the lower front end of the window frames 2, 2, and door mirrors 4, 11 are respectively attached to the outside of each mirror base 3.3.

In this type of automobile, the door mirror 4 is
Since the door mirror 4 protrudes by the dimension Q from the maximum width of the door mirror 4, there is a risk that the door mirror 4 will collide with an external object while driving, and damage the door mirror 4 itself or the external object. However, since it is undesirable for such a situation to occur, it is necessary to provide a structure that, when the door mirror 4 collides with an external object, reduces the impact and reduces damage to the external object and the door mirror 4 itself. As a structure for this purpose, for example, the structure shown in FIGS. 2 and 3 has been devised. In FIGS. 2 and 3, the door mirror 4 is.

a mirror housing 6 that opens toward the rear of the vehicle body 5;
Remote control installed inside the mirror housing 6. The mirror body 8 includes an electric drive device 7 for operation, a mirror body 8 tilted by the electric drive device 7, and a mirror 9 held by the mirror body 8.

One end of a hinge member 10 is pivotally attached to the front end of the base of the mirror housing 6 via a front shaft 11 that extends in the vertical direction, and the other end of the hinge member 10 extends in the vertical direction to the rear of the mirror base 3. It is pivotally connected via a rear shaft 12. As a result, the door mirror 4 is attached to the front shaft 11 or the rear shaft 12.
It can be rotated (tilted) back and forth around the center.

Moreover, one end of a ring 13 is pivotally attached to the mirror base 3 by a pivot 13a, and a tension spring 14 disposed inside the mirror housing 6 is interposed between the link 13 and the mirror housing 6.

As a result, the base end of the mirror housing 6 is brought into contact with the mirror base 3 and maintained in its normal position. In the figure, 15 is a protection tube that protects the electrical wiring to the electric drive device 7.

In a car equipped with such a door mirror 4, even if the door mirror 4 collides with an external object from the front and rear directions, the door mirror 4 resists the spring force of the tension spring 14 and moves back and forth around the front shaft 11 or the rear shaft 12. Therefore, damage to the door mirror 4 itself and external objects can be reduced.

On the other hand, when shipping cars equipped with such door mirrors 4, it is desirable to minimize the space occupied by each car to increase the number of cars shipped. However, since the 1-mirror 4 protrudes laterally by the dimension Q, there is a problem in that the door mirror 4 occupies an extra space corresponding to the protrusion. Therefore, it is conceivable to increase the number of vehicles that can be shipped by loading the vehicles with the door mirrors 4 removed and attaching the door mirrors 4 to the mirror base 3 after landing.

However, in the above-mentioned door mirror 4 with a shock absorbing mechanism,
The mirror housing 6 is elastically supported by the mirror base 3 fixed to the front door 1, and a strong tension spring 14 is provided inside to create a structure that can tilt back and forth when subjected to external force. Therefore, installing the door mirror 4 requires a highly specialized technique, and it is not easy to install the door mirror 4 after landing.For these reasons, cars equipped with a door mirror 4 equipped with a shock absorbing mechanism have generally been equipped with a door mirror 4 as shown in Fig. 1. In addition, since the door mirrors 4 attached to the outside of the vehicle body were still being transported by sea while projecting to the side of the vehicle body 5, it was not possible to increase the number of vehicles shipped, and as a result, transportation costs increased, making it uneconomical.

Therefore, when shipping a car equipped with a door mirror 4, by tilting the mirror housing 6 backward and maintaining this position as shown in FIG. And, mirror 9
Although it is advantageous that the mirror housing 6 is placed close to the vehicle body 5 and covered by the mirror housing 6, there are the following technical difficulties.

That is, the normal usage state of this door mirror 4 (Fig. 2)
In order to bring the mirror housing 6 into contact with the mirror base 3 and maintain its normal posture, the tension spring 14 must be made quite strong. Therefore, a large amount of force is required to tilt the mirror housing 6 rearward as shown in FIG. 3, and if an operator attempts to do this by hand, there is a problem in that a large amount of effort must be expended. Moreover, there is a problem in that a strong locking tool must be used to hold the mirror housing 6 in this tilted position.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a door mirror for an automobile whose mirror housing can be folded easily and quickly without resisting the spring force of a tension spring.

In order to achieve this object, the present invention has a neural plate pivotally attached at its rear end to a mirror base provided on a vehicle door so as to be freely rotatable back and forth, and a mirror housing mounted on one surface of the neutral plate. A tension spring is interposed between the mirror housing and the neutral plate to hold the mirror housing perpendicular to one surface of the neutral plate. A folding spring is compressed and interposed between the neutral plate and the mirror base, and the free end side of the neutral plate and the mirror folding operation means in the vehicle are connected via a wire. This is a characteristic feature.

Hereinafter, this invention will be explained based on FIGS. 4 to 12. In addition, in this description, the same reference numerals are given to parts or members that are the same as or equivalent to the conventional ones, and redundant description will be omitted.

4 to 8, neutral plates 1 to 16 are attached to the rear shaft 12 so as to be rotatable back and forth, and a protrusion 17 is integrally provided on one surface 16a of the neutral plate 16. And this projection 817 has link 1
One end of the link 3 is pivotally supported by a pivot shaft 18 that extends up and down, and a tension spring 14 is interposed between the other end of the link 13 and the mirror housing 6.

Further, on the upper side of the other surface 16b of the neutral plate 16, as shown in FIG. 19, one end of a rotation regulating rod 20 is rotatably mounted on a pivot 21. This rod 20 is connected to the inner wall 3a of the base plate 3.
The rod 20 extends through the rod 20 and protrudes to the opposite side from the neutral plate 16, and a flange 22 for regulating removal is protruded from the other end of the rod 20.

A compression coil spring 23 loosely fitted around the outer periphery of the rod 20 is interposed between the inner i3a and the other surface 16b of the neutral play 1-16 as a folding spring.

Further, on the other surface of the neutral plate 16, a pair of locking hooks 24, 24 are provided at the lower part of the neutral plate 16 at intervals vertically.
is provided protrudingly, and a wire 2 is attached to this locking hook 24.24.
A locking shaft 26 fixed to one end of 5 is rotatably held. The wire 25 is slidably inserted into a guide tube 27, and one end of the guide tube 27 passes through the inner wall 3a. Furthermore, as shown in FIGS. 9 and 10, the guide tube 27 is arranged along the front of the front floor 28 to the vicinity of the driver's seat of the console box 28a.

A parking brake type operating lever 29 is provided near the driver's seat side of the console box 28a as an operating means for folding the mirror, and this operating lever 29 is attached to the front 1-floor 28. When the knob 29a (FIG. 10) of the operating lever 29 is pressed, the locked state of a ratchet locking mechanism (not shown) is released.

Moreover, the first m-th tooth of the plurality of teeth of this ratchet locking mechanism is set so as to be able to withstand a force of at least 25 kg or more.

Furthermore, the other end of the wire 25 described above is attached to the intermediate portion (not shown) of the operating lever 29. The wire 25 is pulled by pulling the operating lever 29.

Although the above-mentioned configuration has been described for one (left side) door mirror 4, the other (right side) door mirror 4' also has the same configuration, so the same parts will be designated with dashed numbers and the explanation will be omitted.

Next, the operation of the automobile door mirror having such a configuration will be explained.

During normal use, by pulling the operating lever 29, the wire 25 is pulled against the spring force of the compression coil spring 23 to keep the free end of the neural plate 16 in contact with the base plate 3. In this state, the operating lever 29 remains in a state triggered by a ratchet locking mechanism (not shown), and the left and right door mirrors 29
, 4' are kept open as shown in FIG.

If, for example, the front surface of the door mirror 4 collides with an external object while the vehicle is traveling with the door mirrors 4, 4' open, the door mirror 4 will receive an external force F from the front as shown in FIG. This external force F causes the hinge member 10 to rotate rearward around the rear shaft 2, and the door mirror 4 to tilt rearward around the rear shaft 12 as shown in FIG. on the other hand.

If the rear surface of the door mirror 4 collides with an external object while the automobile is moving backward, the door mirror 4 will receive an external force F' from the rear surface as shown in FIG. This external force F causes the door mirror 4 to tilt forward about the front shaft 11 as shown in FIG. Moreover, such a forward and backward tilting operation of the door mirror 4 is performed against the spring force of the tension spring 14.

Moreover, this tilting operation absorbs the impact force when the door mirror 4 collides with an external object, thereby reducing damage to the door mirror 4 itself and the external object.

Then, when the external force is removed from the door mirror 4, the door mirror 4 returns to its original state by the spring force of the tension spring 14.

In addition, when loading automobiles, etc., press the knob 29a of the operating lever 29 in FIG. 10 to release the locking by the ratchet locking mechanism (not shown), and then
tilt it forward to release the tension on the wire 25. As a result, the neutral plate 16 and the door mirror 4 are rotated rearward around the rear shaft 12 by the spring force of the compression coil spring 23, the door mirror 4 is folded rearward, and the flange 22 of the rond 20 is folded against the inner wall. 3a and immediately before the door mirror 4 contacts the outer surface of the front door 1, the rearward tilting of the door mirror 4 is stopped. At this time, the tension spring 14
The spring force does not act as a drag force against the folding of the door mirror 4.

Such a folding operation is performed in exactly the same manner for the door mirror 4', and is performed simultaneously with the operation of the door mirror 4.

In the embodiment described above, an example was shown in which the wire 25 linked to the door mirror 4 and the wire linked to the door mirror 4' (path shown) are directly attached to the intermediate part of the operating lever 29, but it is not necessary to do so. do not have. for example,
As shown in Figure 11, the neutral plate of the right door mirror 4' (path shown) and the left door mirror (path shown)
is connected to the neutral plate with one wire 30, and this wire 30 and its guide tubes 31, 3
1' are disposed inside the instrument panel 32, and guide rollers 33, . 34, an engagement member 35 may be engaged with the portion of the wire 30 between the rollers 33 and 34 from above, and the engagement member 35 and the operating lever 29 may be connected by a wire 36. Note that the engaging member 3
5 may be either a molded plate or a roller. In the figure,
37 is a guide tube for the wire 36. In this case, the left and right door mirrors 4 (the other not shown) can be tilted and raised (expanded) in the same state.

Further, in the embodiment described above, the operating lever 29 as an operating means is disposed at the foot of the driver's seat so that the door mirrors 4, 4' can be tilted and raised at the foot, and the neutral plate 16 can be operated at the foot of the driver's seat. Compression coil spring 2
Although an example in which the power is energized in step 3 is shown, the present invention is not necessarily limited to this. For example, as shown in FIG. 12, the neutral plate 16 is biased in the opening direction by a leaf spring 38 (folding spring) fixed to the mirror base 3, and the mirror base 3 fixed to the base member 39 is biased in the opening direction. A space 40 is formed in the space 40, through holes 43 and 44 are formed in the walls 41 and 42 forming this space 40, and a base mounting member 39 fixed to a window frame (not shown) passes through the through hole 43 to connect the space 40 and the vehicle. An operating rod 45 protruding into the room is provided, a knob 46 is provided at one end of the operating rod 45, and a wire 47, one end of which is connected to the new 1 heral plate 16 in the same manner as the wire 25, is inserted through the through hole 44. A pullout prevention piece 48 larger than the through hole 411 and smaller than the through hole 43 is attached to the other end of the wire 47, and the pullout prevention piece 48 and the operating rod 45 are inserted into the space 40.
It is also possible to provide a fixing means for connecting the neutral plays 1-16 to the mirror base 3 and fixing the neutral plays 1-16 to the mirror base 3 with the free ends of the neutral plays 1-16 in contact with the mirror base 3. In this case, the fixing means may include a hook provided on one of the neural plate 16 and the mirror base 3, and a locking pin or a locking hole provided on the other. In this case, by pulling the operating rod 45 from the indoor side against the spring force of the leaf spring 38, the locking hook engages with the locking pin or the locking hole, and the lock release operation member is operated. By doing so, the locking hook can be removed from the locking pin or the locking hole.

As explained above, in this invention, a neutral play 1- is pivoted at its rear end to a mirror base provided on a door of a vehicle so as to be freely rotatable back and forth, and a mirror is mounted on a surface of the neutral play 1-. The housing is attached so that it can rotate freely back and forth,
