Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a foldable door mirror using a link bar and a clamp member.

[Prior Art] Because door mirrors structurally protrude from the outermost line of a vehicle, they are structured to collapse in the direction of an external force when the mirror body comes into contact with a human body or other structure. Various types of door mirrors are known, but those in which a double-hinged link is interposed between the base and the mirror body are widely used because they have an excellent impact avoidance function. For example, the one shown in FIG.
This is a combination of the contents disclosed in the No. 3307532 publication, and the base 41 and mirror body 42
are connected by a U-shaped link 43 to rotatably support the mirror body relative to the base, and a clip mold 47 is attached to the inner end surface 46 of the mirror body at a position facing several protrusions 45 provided on the outer surface 44 of the base. When the mirror body 42 is in a normal use state (upright position), the protrusion 45 is engaged with the clip piece 47, and when an impact is to be avoided, the engagement between the protrusion 35 and the clip piece 37 is released as shown in the figure. There is.

[Problem that the invention aims to solve] Apart from the above-mentioned impact avoidance, door mirrors can be used to narrow the vehicle width as much as possible to increase space utilization efficiency and avoid danger in advance when parking, loading, etc. In order to do this, it is necessary to maintain a forward or backward position.

However, in the link connection type door mirror as shown in FIG.
Although the upright position of the mirror can be maintained by engagement with the mirror body, it is difficult to attach the inclination holding means because the space between the outer surface of the base and the inner end surface of the mirror body is narrow.

The object of the present invention is to provide a door mirror using a bar link that can be reliably maintained in a forward or backward tilted state.

[Means for Solving the Problems] In order to achieve the above object, the door mirror of the present invention has a link bar interposed between the base provided on the vehicle side and the mirror body, so that the mirror body can be tilted in the front and rear directions. In the mounted door mirror; the link bar includes an intermediate portion, a pair of arm portions connected from both ends of the intermediate portion, and upper and lower portions extending from the ends of each arm portion in opposite directions within the same plane and parallel to the intermediate axis. It has a crankshaft shape consisting of a pair of shaft parts, the intermediate part is rotatably supported by the base, and the upper and lower shaft parts are rotatably supported by the base side end surface of the mirror body; When the mirror body is in the normal use position and the rearward position, the arm portion of the link bar is pulled toward the base side and engaged, and when the mirror body is in the forward position, the arm portion of the link bar is disengaged. A clamp is provided on the end face of the mirror body to elastically clamp the outer surface of the holder when the mirror body is in the normal use position, and to release the clamp from the outer surface of the holder when the mirror body is tilted forward or backward. Attaching the members: A spring for holding the mirror body tilted is provided on the mirror body side supporting portion of one of the shaft portions of the link bar, and a tilting angle regulating means is further provided on the shaft supporting portion. It is characterized by being attached.

The backward angle regulating means is formed by a convex strip formed in the direction of the generatrix near the upper end of one shaft of the link bar, and a predetermined angle range on the wall surface of the shaft insertion hole in the supporting portion of the shaft. It is made up of a convex engagement recess.

[Function] Since the present invention has the above-mentioned configuration, in normal use, the holder to which the link bar is engaged is clamped by the clamp member, and the outer surface of the base and the inner end surface of the mirror body are brought into close contact with each other.

When the mirror body is manually tilted backwards or when an external force is applied from the front of the vehicle, the grip between the clamp member and the holder is released and the mirror body rotates backwards, and at the end of the rotation, the spring The lodging state is maintained. Furthermore, when an external force is applied from the rear of the vehicle, the link bar and holder are released from the sandwiched state and can be tilted forward.

[Example] Hereinafter, the present invention will be explained in detail with reference to the drawings.

As shown in FIG. 1, the door mirror 10 includes a base 11 fixed to the outer panel of the vehicle, and a mirror body 12 attached to the base 11 so as to be able to stand up and be retracted.
