Description

[Detailed Description of the Invention] This invention relates to a door mirror for a vehicle in which the angle of the sharp portion can be adjusted from inside the vehicle.

Even if the door mirror is located in a position where the passenger can easily operate it by opening the interior glass, when adjusting the angle of the sharp part in rainy weather, etc., it is difficult to adjust the angle of the sharp part while sitting in the car seat with the window glass closed. It is desirable that the passenger can operate it from inside the vehicle.

Conventionally, 3-wire types using three wires and motor-type types have been widely used, but both have complicated structures, are prone to failure, and are expensive, so they are not popular among the general public. The reality is that it has not been put to practical use in cars.

The object of this invention is to eliminate the above-mentioned drawbacks, provide a door mirror that is simple in structure, can be manufactured at low cost, and can be adjusted from inside the vehicle.

One embodiment of this invention will be explained with reference to the drawings.
In FIGS. 1 to 4, reference numeral 2 denotes a clavicle that holds a sharp portion 1 and has a spherical portion 3 at one end that is seated on a seat 7 of a drum 6.

10 fits into a vertical groove 4 formed in this spherical part 3 on one side,
A pivot part 11 is pivoted by a through shaft 25 so that the center of rotation is at the spherical center of the spherical part 3, and a machine screw 3 is attached to the inner surface of the clavicle 2.
1.32, the recess 12 engages with the torsion bar 24 to which the sharp portion 24a is fixed, the neck 13 corresponds to and loosely fits into the central opening 8 of the drum 6, and the end to which the operating knob 28 is fixed. An operation piece consisting of part 14.

Reference numeral 6 denotes a drum consisting of a peripheral portion 9 that rotatably slides on an inner surface 16a of a base 16, which will be described later, a seat 7 on which the spherical portion 3 of the clavicle 2 is seated, and a central opening 8 formed in the center of the seat 7.

Reference numeral 16 denotes a base in which screw holes 17 and 18 are fitted with screws 29 and 30 for attachment to the vehicle body 33, and a plate spring 15 is arranged, a part of which presses against the drum 6 to be installed inside and provides frictional resistance P. .

Note that the washer 19, compression coil spring 20, washer 21. The locking pin 26 is a component that presses the spherical portion 3 of the clavicle 2 against the seat 7 of the drum 6 so as to generate a frictional resistance Q.

Therefore, when operating, if the operating knob 28 is rotated in the A-B direction, it will fit into the base 16 with a frictional resistance P smaller than the frictional resistance Q between the spherical part 3 of the clavicle 2 and the seat 7 of the drum 6. Since the drum 6 rotates, the clavicle 2 moves in the GH direction without changing its relative position with the drum 6.

Next, if the operating knob 28 is swung in the C-D direction, the drum 6 does not rotate because no load is generated in the direction of rotating the drum 6, and the mirror part 2 is moved against the seat 7 of the drum 6. Since the spherical part 3 slides (swings), the mirror part 2 can be adjusted in the E-F direction.

The amount of rocking at this time is such that the neck 13 of the operating piece 10 comes into contact with the inner end of the central opening 8 of the seat 7.

In this way, the angle of the sharp portion can be adjusted by both operations of the operating piece 10.

Furthermore, when an external force is applied to the sharp portion 1 in the J direction or the The operating piece 10 is restrained.

When a further load is applied, the engagement of the torsion bar 24 with the recess 12 of the pivot portion 11 is released, and the mirror portion 2 rotates around the pivot point (through shaft) 25 independently of the operating piece 10, and the catch seat 7 The top rotates to cushion the impact.

Thus, according to this invention, a door mirror that can be adjusted from inside the vehicle can be manufactured with a simple structure and at low cost.

In particular, when the operation knob 28 is rotated in the A-B direction,
- By changing the location (sliding location) that obtains frictional resistance during the swing operation in the D direction, it is possible to make it possible to ensure that the load for operating the operating knob 28 hardly differs depending on the operating direction. becomes.

Claims (1)

[Claims for Utility Model Registration] A door mirror (a) characterized by having the following requirements: An operating piece with an operating knob fixed to one end is rotatably pivoted on the lower spherical part of the clavicle that holds the mirror. and this operating piece is restrained by an elastic body at a predetermined relative position to the clavicle. (b) A drum rotatable with frictional resistance P is interposed on a base fixed to a part of the vehicle body. (c) The lower spherical part of the clavicle is seated on a seat formed on the upper part of the drum, and the two are pressed against each other by an elastic body to generate frictional resistance Q during relative movement between the two. b) When rotating the operating knob around its axis, the operating piece and drum should not rotate relative to each other. (E) Frictional resistance P is smaller than frictional resistance Q.
