Description

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

Since door mirrors are generally installed protruding from the sides of the automobile body, there is a risk of them colliding with external obstacles. Buffer-type door mirrors are used to reduce damage to other objects and prevent damage to the door mirror itself when a door mirror collides with the vehicle.

FIG. 1 is a plan view showing an example of a conventionally used shock-absorbing door mirror, in which 1 is a mirror base fixed to a vehicle body, and 2 is a mirror housing that supports a mirror (not shown). In the figure, the downward direction of the paper is the traveling direction of the automobile, and the mirror housing 2 drawn by a solid line is the normal mounting position.

The above-mentioned mirror base 1 and mirror housing 2 are brought into contact with each other via a rotatable fulcrum 3, and a tension spring 4 is interposed and engaged between the two, so that the mirror housing 2 is attached toward the mirror base 1. It is in force. 5 is a spring hanger fixed to the mirror housing 2; 7 is a lever rotatably supported on the mirror base 1 by a pin 6; a hole 7a is bored in its free end, and the tension spring 4 is hooked thereon; It is being

In the door mirror configured as described above, when an external force is applied to the mirror housing 2 as shown by the arrow A, the mirror housing 2 tilts around the fulcrum 3 as shown by the arrow B while resisting the biasing force of the tension spring 4. to reduce the impact of external forces. A virtual line C indicates a state in which the mirror housing 2 is tilted.

When a car equipped with the above-mentioned shock-absorbing door mirrors is loaded onto a ship or the like and transported, the door mirrors protrude to the sides of the vehicle body, which occupies extra space, which is uneconomical. In order to improve this uneconomical situation, the mirror housing 2 is tilted by hand in the direction of the arrow B using the above-mentioned tilting mechanism, and the imaginary line C
It is practiced to take the tilted posture shown in and hold this tilted posture C using some kind of locking means. However, when the mirror housing 2 is kept in the tilted position C, the tension spring 4 is stretched and stretched as shown by the imaginary line 4', so if the mirror housing 2 is kept in this state for a long time, the tension spring There is a problem that plastic deformation (so-called sagging) occurs. Further, there are other problems such as the need for a means for locking the mirror housing 2 in the tilted position C to be strong enough to withstand large forces.

The present invention improves the above-mentioned problems of the conventional technology, maintains the mirror housing in the tilted position C, reduces the tension of the tension spring, and returns the mirror housing to its normal position. It is an object of the present invention to provide a tilting posture holding device for a door mirror that can be operated extremely simply and easily.

In order to achieve the above object, the present invention brings a mirror base fixed to the automobile body into contact with a mirror housing supporting the mirror, and also inserts a tension spring between the mirror base and the mirror housing. In the buffer type door mirror, the base of the hook plate is connected to one end of the tension spring, and the tip of the hook plate forms a hook shape with a sloped head, and the mirror base is connected to the base of the hook plate. fixing a pin capable of slidingly contacting the slope of the head of the hook plate and engaging with the hook when the mirror base and the mirror housing abut, and facing the bottom wall of the mirror housing of the hook plate; A pin hole is provided at the position, and a temporary fixing pin for temporarily fixing the hook plate to the seat provided on the mirror base side of the bottom wall of the mirror housing when the mirror housing is held in a tilted position is inserted into the pin hole. Extending the temporary fixing pin to form an insertion pin part into the mirror base side that is integral with the temporary fixing pin, forming a bracket into which the pin part integral with the temporary fixing pin can be inserted into the mirror base, and fixing the temporary fixing pin integrally with the temporary fixing pin. The present invention is characterized in that the tilted posture of the mirror housing is maintained by temporarily fixing the hook plate to the mirror housing side with a pin and inserting the insertion pin portion into a bracket formed on the mirror base.

An embodiment of the present invention will now be described with reference to Figs.

Fig. 2 is a schematic plan view showing the door mirror of the present invention held in a normal position; Fig. 3 is a perspective view of the main parts of the mirror housing held in a tilted position;
FIG. 4 is a partially cutaway plan view. The mirror base 1, mirror housing 2, fulcrum 3, tension spring 4, and pin 6 fixed to the mirror base, which have the same drawing reference numbers as the conventional door mirror (Fig. 1), are the same as or similar to the conventional door mirror. It is a constituent member of The hook plate 8 in this embodiment is similar to the lever 7 in the conventional type.
This is a structural member corresponding to the above, which has a hook shape near its tip, a slope 8a on its head, and a pin hole in the vicinity where the hook plate 8 faces the bottom wall 2a of the mirror housing 2. 8b, and constitutes a temporary fixing pin 9 that fits into this pin hole 8b.

2b is a window-shaped opening provided in the bottom wall 2a so that the hook plate 8 can pass therethrough. As shown in FIG. 3, a pin hole 8 is provided near the edge of this opening 2b.
Seats 10, 10 are formed to abut and support the temporary fixing pin 9 inserted through b.

Then, two places of the temporary fixing pin 9 are bent at right angles to form a crank shape, and the other end is used as a pin part 9' for insertion into the base side, and on the other hand, the pin part 9' is inserted into the mirror base. A bracket 11 is formed so that the pin portion 9' can be inserted into the bracket 11 on the base side when the mirror housing 2 is tilted.

Since the door mirror tilting posture holding device according to the present invention has the above-described configuration, as shown in FIGS. 3 and 4, when the temporary fixing pin 9 is inserted into the pin hole 8b of the hook plate 8, When the hook-shaped portion 8 is removed from the pin 6, the tension spring 4 urges the hook plate 8 in the direction of pulling it into the mirror housing 2 (in the direction of arrow D), and the hook plate 8 pulls the temporary fixing pin 9 into the seat 10.
The mirror housing 2 can now be freely tilted about the fulcrum 3, and when tilted in the direction of arrow B, the pin portion 9' that is integral with the temporary fixing pin 9 is fixed. Bracket 1
1, the mirror housing 2 will be placed at the fulcrum 3.
Rotation around the body is stopped and the body is kept in a tilted position.
In this state, the tension spring 4 is not strongly stretched, so there is no risk of it becoming sagging.

To carry out multiple operations from the above-described tilted position to the normal operating state, the pin portion 9' integral with the temporary fixing pin 9 is removed from the bracket 11, as shown in FIG. This allows the mirror housing 2 to freely rotate around the fulcrum 3. In this state, when the mirror housing 2 is turned by hand in the direction of arrow G, the tip of the hook plate 8 comes into contact with the pin 6, resulting in the state shown in FIG. 6. When a force is further applied in the direction of arrow G to the mirror housing, the hook plate 8
The hook plate 8 is pivoted about the temporary fixing pin 9 in the direction of arrow F so that the hook-shaped portion can be hooked onto the pin 6. FIG. 7 is a perspective view of the hook plate 8 hooked onto the pin 6. After hooking the hook-shaped portion of the hook plate 8 onto the pin 6 in this manner, applying manual force to the mirror housing 2 and slightly turning it in the direction of the arrow H, as shown in FIGS. 8 and 9, The temporary fixing pin 9 is separated from the seat 10, and the temporary fixing pin 9 easily fits into the pin hole 8 of the hook plate 8.
b, or the temporary fixing pin 9 will fall off due to its own weight.

After the hook-shaped portion of the hook plate 8 is hooked onto the pin 6 by operating as described above and the temporary fixing pin 9 is removed from the hook plate 8, the force applied by the hand in the direction of the arrow H is relaxed. and mirror housing 2
is rotated in the opposite direction of the arrow H by the biasing force of the tension spring 4, contacts the mirror base 1, and is restored to its normal position as shown by the solid line in FIG.

As described above, according to the present invention, by temporarily fixing the hook plate to the mirror housing side using the temporary fixing pin and inserting the pin part integral with the temporary fixing pin into the bracket formed on the mirror base, It is possible to hold the mirror housing in a tilted position and prevent excessive tension from being applied to the tension spring, and further,
The effect is that the operation of restoring the tilted state to the normal position can be performed extremely simply and easily.
