Abstract

PURPOSE:To facilitate a change in orientation of a mirror housing, by a method wherein a bracket is rotatably mounted to a mirror base through a spring means which energizes a repulsion force, and a tension sleeve is located between the bracket and the mirror housing. CONSTITUTION:A mirror housing 2 is inclined and rotated counterclockwisely through an external force is a direction A as a tension spring 7 is forcibly expanded. When the tension of the spring 7 exceeds the energizing force of a coil spring 15, a rotary bracket 8' is rotated counterclockwise. Along with such rotation, an axle 11, supporting the spring 15 to a bracket 8', is also rotated couterclockwise. When the axle 11 is rotated across a line, interconnecting an axle 6 of the bracket 8' and an axle 14 of the mirror base 1' for supporting the spring 15, the energizing force of the spring 15 is exerted in a direction in which counterclockwise rotation of the bracket 8' is assisted. This causes the mirror housing 2 to be held in an inclining orientation. The mirror housing 2, if it is rotated clockwise against the energizing force of the spring 15, is returned to a regular orientation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for tilting a mirror housing of a shock-absorbing door mirror.

Door mirrors are installed so that they protrude from the side of the vehicle, so
There are some bumps in the road where you collide with obstacles while driving.

In the event of a collision, shock-absorbing door mirrors are used to cushion the impact.

gi diagram shows 01 examples of buffer type door mirrors conventionally used (
(Refer to Japanese Utility Model Publication No. 57-96403) FIG.

1 is a mirror pace fixed to the single unit side, 2 is a mirror 3v
I-supported mirror housing. A hinge member 4 is interposed between the mirror paste 1 and the mirror housing 2, and is made of bran.

That is, lfi of the hinge member 4 is rotatably attached to the mirror housing 2 via the front side s5, and the other end is attached to the mirror pace l via the rear side axis 6, respectively.

In order to elastically support each of the mirror housings 2t in the normal posture shown in FIG. 1, a tension spring 7 is provided that biases the mirror housing 2 in the direction of pressing the mirror housing 2 toward the mirror pace 1.

One end of this tension spring 7 is attached to the mirror housing 2, and the other end is attached to a spring hook lO.
and is attached to the mirror pace 1 via a rotation bracket 8. At the above-mentioned rotation bracket 8, one end t is attached.
- It is rotatably attached to the mirror base 1 by a rear shaft 6, and the other end is attached to the mirror base l by a screw 9.
Vc is fixed. 11 is -nself sgeling hook 1
When the mirror housing 2 of the above-mentioned 5l HI type door mirror is subjected to an external force in the direction of the arrow, the mirror housing 2 is moved along with the hinge member 4 to the rear shaft 6Ll. The center is tilted in the direction of rotation shown in the figure, resulting in the state shown in Figure 2. The above #1 is carried out against the biasing force of the tension spring 7, so the gun sword is sucked into the field. Further, when the external force disappears, the biasing force of the tension spring 7 causes the robot to return to the normal posture shown in FIG.

The door mirrors have the aforementioned μ openings (protruding to the sides of the vehicle body, so they can be placed between narrow obstacles, such as when driving in a garage). f- If it passes, it becomes a member. For this reason, it would be very convenient if the mirror housing 2 could be held in the tilted position as shown in FIG. 2, but since the spring force of the tension spring 7 is quite strong, it is not easy to hold it in this position.

A similar problem occurs when shipping automobiles equipped with door mirrors, and in order to shorten the distance between automobiles and reduce transportation costs, the mirror housing is held in an inclined position as described below.

1 pJa mirror housing 2 as shown in the picture 1
ltll (on the front side with respect to the car body) Tilt and rotate the VC to remove the screw 9t and remove the rotation bracket 8.
Make it possible to rotate around the axis 6. Next, when the vehicle body is tilted to the rear side as shown in FIG. For example, the U-shaped lock 1 shown in the diagram
The state shown in Figure Is4 (tilted posture) can be maintained using a locking tool such as 2.

However, it is extremely troublesome to handle each screw 9 and attach the U-shaped lock 12t-Ml during daily driving such as when parking the vehicle in a garage.

The present invention was made in view of the above-mentioned circumstances, and it is possible to quickly and easily hold the mirror housing in a tilted position with a simple operation.
9. It is an object of the present invention to provide a tilting device t' that can tilt the bale base into a normal posture.

The door of the present invention for kniting purpose of upper dC,
The mirror tilting device has one end of the hinge wall material coated with bran on the single solid mirror base, a mirror housing on the other end of the hinge member, and a bran layer on the other end of the hinge wall material, and In a buffer-type door mirror in which a tension spring is layered between the bracket and the mirror housing, which are axially layered so that the rotatable bracket and the mirror base can be rotated, a repulsive force is created between the rotatable bracket and the mirror base. Did you provide a spring means for biasing it? 1-% mold.

Next, one embodiment of the present invention will be described with reference to FIGS. 5 to 9. This embodiment is an improved version of the conventional shock-absorbing door mirror described above by applying the present invention. 4. The front shaft 5, the rear shaft 6, the tension spring 7, and the spring hooks 1O1 and @11 are the same or similar structural members as in the conventional example.・1'C shown with a dash is the same as in the conventional example. The member 8' corresponding to the mirror base l is also the rotating bracket 8.
This is a member corresponding to.

The rotating bracket 8' of this embodiment is rotated by the rear shaft 6! Although it is similar to the conventional device in that E11 can be pivoted to the mirror base 1', it is not attached to the mirror base 1' by a T screw (.9 in the conventional example) near its free end.

As shown in Figure 5, the platen fixed to the mirror base 1')
13 is completely solidified and supports the shaft 14 in one leg.

A torsion coil spring 1st is compressed between the shafts 11 and 14, and the rotating bracket 8' and the mirror base 1' are connected via the shafts 11 and 14t. A repulsive force is applied in a direction that causes them to separate from each other.

The position of the shaft 14 is set to be offset from the mirror housing 1lI4c compared to the line B connecting the shaft 11 and the rear surface 6 to t. As a result, the torsion coil spring 15 applies a rotation force to the rotation bracket 8' in the clockwise direction as shown in the figure.
The rotating bracket 8' acts to press the rotating bracket 8' toward the mirror pace 1'. For this reason, the rotation bracket 8
Even if it is not screwed to the 'hammirror base 1', it will come into contact with the mirror base 1' and be stable, and the rotation bracket 8
' attracts the mirror housing 2 via the tension spring 7 and maintains the mirror housing 2 in its normal posture as shown in FIG.

In this embodiment, the above torsion coil spring 1
Spring means (not shown) for assisting in holding the pivot bracket 8' in position by 5't-ff. This spring means will be described later with reference to FIGS. 8 and 9.

When the mirror housing 2 receives an external force in the direction of the arrow in the normal posture shown in FIG.
' while being stretched out, it is tilted and rotated in the counterclockwise direction in the figure around the rear shaft 6. As the tension spring 7 expands, its tension increases, and the biasing force in the counterclockwise direction against the rotation bracket 8' increases. When the biasing force in the direction becomes larger than the biasing force in the direction, (b) the movable bracket 8'
The coil spring 15 rotates counterclockwise while being compressed.

Along with the above-mentioned counterclockwise rotation, the shaft 11 rotates counterclockwise around the rear shaft 6, but when it crosses the line Ci connecting the rear shaft 6 and the shaft 14, the torsion coil spring 15 The biasing force acts to assist the counterclockwise rotation of the bracket 8', resulting in the state shown in FIG. 6. In this state, the torsion coil ring 15 applies a counterclockwise rotational force to the mirror housing 2 via the rotation bracket 8' to hold the mirror housing 2 in the tilted position as shown in the figure. Due to the action, the door mirror tilt f of this embodiment
When an external force is applied to the mirror housing 2 in the direction of arrow A, the device tilts rearward as shown in FIG. 6 to function to alleviate the impact. Moreover, even when a hand force is applied in the direction of the arrow A, the tilting posture is maintained after the tilting is performed in the same manner. To restore this to the normal posture (Fig. 5), apply manual force to the mirror housing 2, and apply torsion coil spring 1.
All you have to do is turn it clockwise against the biasing force 5.

Furthermore, when the mirror housing 2 is in the normal posture as shown in Fig. 5, and an external force is applied in the direction of the arrow, the mirror housing 2 resists the biasing force of the tension spring 7 and rotates 9 times clockwise around @11111J @5. Then, the state shown in FIG. 7 is reached, and the phase of the shock t-slows. In this case, there is a lack of tension in the tension spring 7.
Since the distance d between the line of action of F and the rear shaft 6 is narrowed, the counterclockwise rotational moment exerted on the bracket 8' is small, and the biasing force of the spring 15 of the bracket 8' causes the mirror base l' Shichimi is in a posture that touches the body.

FIG. 8 is a perspective view of the mirror housing 2 as seen in the direction of arrow E, with the mirror housing 2 tilted rearward as shown in FIG. 6.

In order to reliably maintain the state in which the mirror base 1 is in contact with the mirror base 1 in the m direction 1a, that is, the normal posture, in this embodiment, the spring retaining pieces are cut and raised on the bracket 8' to support both ends of the rod-like sedge ring 16, and the mirror base 1 is A hook 17t, which is connected to the rod-like spring 16, is fixed to the seat side of the seat.

FIG. 9 is a sectional view of the rod-like spring 16 in a state in which it is engaged with the hook 17. mirror housing.

Immediately before the bracket 2 rotates with the bracket 8' and assumes the normal position, the rod-like spring 16 contacts the 7 claw 17 and is bent, and when the normal position is achieved, the rod spring 16 engages as shown in Figure 9. Further, when the mirror housing 2 in the normal posture rotates together with the bracket 8' and begins to tilt, the rod-like spring 16 acts to elastically prevent the above-mentioned rotation m, thereby maintaining the normal posture. When the mirror housing 2 receives a large rotational force, the rod-like spring 16 deforms and comes off from the seven hooks 17.

By providing the rod-like spring 16 and the hook 17t, the mirror housing 2 is reliably maintained in its normal posture, and there is no chance of it vibrating during running or tilting due to a slight external force.

As detailed above, the door mirror tilting of the present invention! Ifr
