2. Description of the Related Art A method of mounting a dropping mirror for a vehicle requires a step.
The mounting part that supports the base of the vehicle is attached to the front of the ceiling of the passenger compartment
There are things that adhere to windshields. Izu
These are also located above the driver's head.
Avoid sudden injuries by hitting your head or face when bumping
That is what it is . 5 to 7 show a conventional glass contact.
Explanatory diagram showing a mounting example of a wearing type inner mirror ,
It is a partial enlarged view and an operation explanatory view at the time of a collision. Inner mirror M is sometimes head hits even while wearing the temporarily seat belt like shock unexpectedly to relax the impact
Therefore, an inner mirror M in which the mirror is dropped is used to prevent the occurrence of injury.

[0003] Mirror M This is a stay 32 provided with the pivot 31 for supporting the mirror housing 30, in order to fall off can hold the base of the stay 32, the stay 3
3 and the upper base 33 via a spring plate 34 is fixed by a lock bolt 35, thereafter the lower base 37 fixed to the windshield (front glass) 36, securing the upper portion base 33 by mounting screws 38 .

[0004] The spring plate 34 is provided with four cross-shaped projections 39 for locking the head 35a of the lock bolt 35 at the center thereof, and a locking hole 40 at the center thereof. ing.

[0005] The inner mirror M is a driver.
Head hits the mirror housing 30, an external force or cult arrow F direction in the stay 32, the base portion of the stay 32 is rotated P of the upper end portion as a fulcrum. At that time , lock bolt 35
, A rearward pulling force is generated, and the head of the lock bolt 35 comes out of the locking hole 40 while elastically deforming the locking claw 39, and the mirror housing 30 is dropped together with the stay 32.

[0006]

However, in the conventional example , as shown in FIG. 5 , an external force (load) is applied to the upper base 33.
When acting within the angle θ on the extension line connecting the engaging portion of the stay 32 and the center of the pivot 31 , the stay does not act as a force for rotating, and the mirror body is pushed in the direction of the window glass. In order to work, it does not function as a buffer mechanism.

[0007] In the above case, it is easy to fall off.
For this purpose, the base with the stay
It is necessary to incorporate means for sliding off the adhered base . As a result, there arises a problem that the dropping mechanism becomes complicated and the number of components increases, which increases the cost. As the other problems, and to arrange Rashi not the Mounting glass portion of the stay in order to drop out moment is more likely to occur, eye or we the glass mounting portion of the driver will be seen, supposed to be compromising the aesthetics glass there is a disadvantage that the superiority of the adhesive formula mirror is eliminated.

Further, according to domestic laws and regulations, the tip of the stay
It is stipulated that it must fall off at a load of 45 kgf or less with a load applied from a range supposed to be a 45-degree cone with the pivot as the center. Was.

[0009]

Accordingly, the present invention provides a stay
Glass mounting part is invisible to the driver while driving
To the mirror housing windscreen.
Place the glass mount in the projection plane of the
Thus, the above problem has been solved. That is,
The falling mirror is a stay that holds the mirror housing.
At the end of the mirror, which is the movable center of the mirror housing
With a cone of approximately 45 degrees around the pivot.
Supports the stay base at a position outside the specified angle range
Mirrors for vehicles with glass mounting parts
The glass mounting portion is used to assemble the stay base.
Base and lower base glued to the windshield
Between the mounting screws for fixing the bases and the bases.
Leaf spring having a pawl interposed between the leaf spring and the upper base
A lock bolt that fixes
The mounting is not visible from the driver's
So that it is located within the projection plane of the mirror housing
Glue the lower base of this mounting part to the windshield
Glass-bonded inner mirror, characterized in that:
It is .

[0010]

[Effect of the invention] The driver's head is a mirror when stopping suddenly
When it hits the housing , the impact acts as a fall-off external force
Then the mirror housing comes off with the stay. That is, the pivot at the tip of the stay holding the mirror housing
Within an angle assuming a cone of at least 45 degrees centered on
When external force acts on the upper base and the stay,
Negative on the extension line connecting the engagement point of
θ, the glass mounting part is
At a position deviated from the range of angles assumed cone, moreover since it is disposed in the projection plane of the mirror <br/> over housing, dropping moment in the glass mounting portion is transmitted through the stay, to fix the stay If the external force is greater than the locking force between the leaf spring and the lock bolt, the lock bolt comes off the leaf spring and the mirror falls off.

Bonding the base over scan 3, whereas, under the upper base 6 attached to the stay 5 which supports the mirror housing 12 by mounting screws 4
It is fixed to the base 3 .

[0012] The upper base over the scan 6 not have a through-hole 7 substantially at the center
You. A leaf spring 10 having an outer periphery slightly larger than the through hole 7 and having a plurality of claws 8 and a through hole 9 at the center is disposed on the through hole 7 of the base 6. make integrated base of the base 6 and the stay 5 is inserted through the male threaded portion of the locking bolt 11 within.

[0013] scan tape 5, the top by means of a locking bolt 11
The plate spring 10 is fixed to the base 3 at this time.
The head 11a of the lock bolt 11 is held by the claw 8 so that the mirror 1 does not easily fall off even if it is subjected to vibration or some shock during traveling. The leaf spring 10
Is the center of rotation of the mirror housing 12 pivots 1
45 from the direction assuming an approximately 45-degree cone centered at 3
When an external force of not less than kgf is applied, the head 11a is pulled out of the through hole 9 against the elasticity of the claw 8, and the stay is held so that the stay is dropped from the upper base 6.

As an example, the shape of the stay 5 can be substantially Z-shaped as shown in FIG. 1, but is not limited to this.
No. That is, the stay 5 of the present invention locks the plate spring provided on the glass mounting portion A when an external force acts on the mirror 1.
In the form in which the pulling force acts in the direction in which the bolt is pulled out, that is, in the direction opposite to the direction of the windshield 2, and
Any shape may be used as long as it is located within the projection plane of the mirror housing 12 with respect to the windshield .

[0015] distal end portion of the stay 5 as before mentioned forms a pivot 13 for supporting the mirror housing 12, or
At the base of the stay, a female screw for screwing the screw of the lock bolt 11 is engraved on a flat surface to be joined to the upper base 6.

At the base of the stay 5 , the pivot 1
A glass mounting portion A composed of a pair of upper and lower bases 3 and 6 is provided at a position deviating from a projection plane assuming an approximately 45-degree cone with the center at 3 and within the projection plane of the mirror housing.
In such a configuration , the driver 's eyes
The mounting portion A is located in the projection plane of the mirror housing 12 and cannot be visually recognized by the driver.

[0017] Thus, the present invention is, above the Mounting glass portion
By placing it at a specific position, the moment in the direction applied to the mirror 1 acts on the force to pull the stay, and the base
6 separates from the lower base 3 of the mounting part A, and the mirror 1 comes off.

Conventionally, approximately 45 around the pivot 13
Since the glass mounting portion A was located within the range of the degree, the direction of the impact force almost coincided with the direction of the mounting portion A, and only the pressing force was generated without generating a dropping moment. The device is designed to be approximately 45 around the pivot 13.
Field from which direction within the range of a cone of degrees
In any case , it acts as a dropping moment.

For example, when a force from the front (lower right in the figure) toward the back (upper left in the figure) of the X axis in FIG.
A force that causes the mirror 1 to move to the left in the drawing is generated, and that force generates a force that pulls the stay 5 to the left via the pivot 13, thereby pulling the upper base 6 integrated with the stay 5 toward the user.

Then, the head 11a of the lock bolt 11 fixed to the stay 5 is pulled by the stay 5, and the plate spring 10
The claw 8 is elastically deformed without being able to withstand the force, the head 11a comes out of the through hole 9, and the locked state between the stay 5 and the upper base 6 is released.

According to the present invention, the pivot is substantially centered.
At a position outside the angle range assuming a 45-degree cone,
As a result of arranging the glass mounting portion for supporting the stay base, before
It goes without saying that the position of the glass mounting portion, in which the external force applied to the mirror acts in the direction in which the lock bolt is pulled, is arbitrarily changed in accordance with the left-hand drive or right-hand drive vehicle.

[0022]

[Effect of the invention] In the present invention, the glass mounting part is inside the pivot.
It is arranged out of the assumed position of the 45-degree cone as the center
So that external force from any direction within the cone
A moment is likely to be generated for dropping.
Even at the site where the highest moment does not occur, in the case towards the external force is greater than the locking force of the plate spring and the lock bolt can be dropped mirrors off the lock bolt from the leaf spring.

Further, the glass mounting portion is a mirror housing.
It is located in the projection plane of the
The driver's direct view is wide, so it is safe
And it does not spoil the aesthetics.

The present invention is simple and has few parts, so
Durability and low cost can be realized .
