Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to front and rear foldable door mirrors attached to the doors of automobiles.

Currently, automobile doors are equipped with front and rear folding door mirrors whose housings will fall forward or backward in the event of a collision with a pedestrian or the like, thereby minimizing damage to the pedestrian or the like. This door mirror is the first
As shown in FIGS. 3 to 3, a connecting plate 3 is interposed between the housing 1 and the stay 2, one end of the connecting plate 3 is pivotally connected to the housing 1, and the other end is pivotally connected to the stay 2. and the stay 2 are connected by a return spring 4 disposed in the center of the housing 1. In this type of door mirror, the front and rear ends of the housing 1 on the stay side are cut out to allow the connecting plate 3 to pivot. part is exposed to the outside. As a result, rainwater enters into the housing 1 through the notches 5 and 6 of the housing 1, causing rust and clogging of the shaft fittings, making the folding operation of the housing 1 unsmooth, and as a result, the folding door mirror In addition, when the vehicle collides with a pedestrian or the like, the exposed pivot portion of the connecting plate 3 may cause injury. Furthermore, since the shaft attachment portion is directly exposed between the housing 1 and the stay 2, the appearance is poor and the design of the automobile is impaired.

The present invention aims to eliminate these drawbacks and provide a door mirror that can be used safely for a long period of time and has a good appearance.

That is, the present invention provides a double-hinged folding mirror with a front edge that faces the stay from the front and rear walls of the housing, covers both axes of the connecting plate, and that can come into close contact with the housing mounting surface of the stay when the housing is raised. Each of the rear edges extends, and a groove with an arcuate cross section is formed in the housing mounting surface of the stay into which the front or rear edge that rotates when the housing is collapsed. With this structure, the shaft of the double-hinged connecting plate is covered by the front and rear edges and is not exposed to the outside.
It has a good appearance, prevents rainwater from entering the shaft attachment part and prevents rust, and allows the double hinge to maintain its functionality for a long time.

Next, embodiments of the present invention will be described based on the drawings.

Fig. 4 is a front view of the door mirror of the present invention, and Fig. 5 is a cross-sectional plan view of the housing attachment part.
1 is a housing on which the mirror 12 is attached, 13 is a return spring, 14 is a stay, 15 is a spring locking protrusion formed protruding from the stay, and 16 is a double hinge type interposed between the housing 11 and the stay 14. It is a connecting plate.

The connecting plate 16 has two front and rear axes, one shaft 19 is supported by a bearing part 18 provided at the inner end of the front wall of the housing 11, and the other shaft 21 is supported by a bearing part protruding from the housing mounting surface of the stay 14. It is supported by section 20. The housing 11 has a return spring 13 disposed approximately at the center inside thereof, and has one end connected to the inside of the housing 11 and the other end connected to a protrusion 15 protruding from the stay 14 to constantly urge the housing 11 to stand up. I'll keep it. Further, both shafts 1 of the connecting plate 16 are arranged toward the stay 14 from the front and rear walls of the housing 11.
6 and 21 and which can come into close contact with the housing mounting surface of the stay when the housing is erected.
b and trailing edge 11a, respectively.

On the other hand, grooves 22 and 23 having an arcuate cross section are formed in the housing mounting surface of the stay 14. The grooves 22 and 23 having an arcuate cross section are formed on the front edge 11b of the housing 11 when the housing 11 is laid down in any direction.
Alternatively, the rear edge 11a is provided so that it can be inserted without interfering with the stay 14 or damaging the outer surface of the stay. That is, the groove 22 is formed by an arc whose radius is the axis 19 of the connecting plate 16 and the tip of the front edge 11b of the housing 16, and the groove 23 is formed by the axis 21.
and a circular arc whose radius is the tip of the rear edge 11a of the housing 16. Reference numeral 17 is a through hole provided in the center of the connecting plate 16, and when the housing 11 is in the upright state (normal position) by passing the protrusion 15 of the stay 14 through the through hole 17, Protrusion 1
5 and the connecting plate 16 are prevented from coming into contact with each other.

As described above, in the front and rear foldable door mirror, the housing 11 is attached to the housing attachment surface of the stay 14 with the double hinge type connecting plate 16 interposed therebetween. The housing 11 is constantly pressed against the mounting surface by the tension of the spring 13, and is set in an upright state toward the outside of the vehicle as shown in FIGS. 4 and 5. In this state, the front edge 11b of the housing
Since the rear edge 11a is in close contact with the upper ends of the grooves 22 and 23 of the stay 14, rainwater is prevented from entering the shaft portion of the double hinge type connecting plate 16. Further, the shafts 19 and 21 have a front edge 11b and a rear edge 11a.
Each is covered by a cover and is not exposed to the outside.

Next, when the housing 11 collides with a pedestrian's property, the impact causes the housing 11 to move against the shaft 19.
Or rotate forward or backward around 21. At this time, a rear edge 11a or a front edge 11b formed at the stay side end of the front and rear walls of the housing 11
fits into a groove 22 or 23 having an arcuate cross section provided in the stay 14, and rotates without interfering with the stay 14. For example, when a collision occurs from the front, the housing 11 falls to the rear of the vehicle as shown by the chain line in FIG. .

As described above, the front and rear foldable door mirror according to the present invention is a foldable door mirror equipped with a circular double-hinged connecting plate, in which the front and rear walls of the housing are directed toward the stay, and both axes of the connecting plate are covered. , and extending a front edge and a rear edge that can come into close contact with the housing mounting surface of the stay when the housing is erected,
Since the housing mounting surface of the stay is formed with an arc-shaped groove into which the front or rear edge that rotates when the housing is collapsed, even though the housing is normally in close contact with the stay, when the housing is collapsed, The stay can be tilted back and forth accurately without damaging the outer surface of the stay. Furthermore, since the housing is in close contact with the stay, the connecting plates and bearings are not visible from the outside at all times, simplifying the appearance and giving it a good appearance. Also, there is no chance of rainwater entering the housing, causing rust on the shaft fittings, or loss of function as a hinge.
Therefore, it can be used safely for a long period of time. Furthermore, since the metal connecting plate is not exposed, even if the vehicle collides with a pedestrian or the like, it does not give off an appearance.
