Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door mirror for an automobile, and particularly to a door mirror suitable for a manually operated remote control door mirror.

FIG. 1 is a horizontal sectional view of an example of a remote-controlled door mirror. A mirror body 2 to which a mirror 1 is fixed is tiltably supported by a mirror housing 4 via a pivot joint 3. A mirror base 5 supports the mirror housing 4 described above and is fixed to the automobile body 6. The mirror housing 4 is elastically biased toward the mirror base 5 by a tension spring 7, and has a structure that can tilt around a fulcrum 8 or 9 to buffer the impact when a large external force is applied. It is.

Manual or electric operating means are provided for tilting the mirror body 2 about the pivot joint 3 as desired. The remote control type door mirror to which the present invention is applied is manually operated using an operating lever 10 and a transmission link/lever device 11.

The operating lever 10 is rotatably supported by a ball bearing 10a, and can be rotated in the directions of arrows A and B and in the directions of arrows C and D by holding the handle 10b by hand. This rotation is transmitted via the link lever device 11 to the mirror body 2, which rotates around the pivot joint 3 by the arrows A',
B', and rotated as shown by arrows C' and D'. The detailed structure of this part is as follows.

The lever link mechanism 11 described above is mainly composed of a lever 11a and a link 11b. This lever 11a is rotatably supported by a pin 11c, and is rotated by an operating lever 10 via a link 11b. The rotation of the lever 11a is transmitted to the mirror body 2 via the interlocking mechanism E. FIG. 2 shows a perspective view of the interlocking mechanism E described above. Guides 2a and 2b and 2c and 2d facing each other vertically are integrally formed on the back surface of the mirror body 2 so as to form a left and right pair. The tip of the lever 11a is inserted between the guides 2a and 2c, and the pin 11d is fixed to the tip of the lever 11a so that the pin 11d protrudes from both the left and right sides of the lever 11a, and the pin 11d is inserted into the guide 2a. and the guide 2b, and between the guide 2c and the guide 2d so as to be able to freely slide in the direction of the coordinate axis Y-Y. This allows the movement of the tip of the lever 11a in the coordinate axis Z-Z direction and the coordinate axis Y-
The rotation around Y is transmitted to the mirror body 2.

The coordinate axis Y includes the center line W of the pin 11d.
A cross-sectional view taken along a plane perpendicular to -Y is shown in FIG. Reference numeral 12 denotes a holder (not shown in FIG. 2) provided for backing up and reinforcing the guides 2a and 2c.

In the conventional transmission mechanism explained above,
Since the pin 11d and the guides 2a, 2b, 2c, and 2d are in direct contact and in a line contact state, the sliding surfaces are likely to be worn. In particular, since the pin 11d is generally made of a metal material and the guides 2a to 2d are made of synthetic resin integrally with the mirror body, the service life of the entire automobile door mirror is shortened due to early wear of the guide. be shortened.

In the present invention, a pair of vertically opposing guides are provided on the rear surface of the mirror body 2, which is tiltably supported as described above, and a pin is fixed through the tip of the operating lever so that the pin protrudes to the left and right of the lever. To provide a door mirror for an automobile in which a pin is slidably fitted between the above-mentioned vertically opposing guides, and the durability can be improved by preventing wear of the sliding part between the pin and the guide in a remote control door mirror. The purpose is to

In order to achieve the above object, the present invention provides a member that connects a pair of pin covers that fit and hold a pin fixedly fixed to the lever, and a recess into which the tip of the lever can be inserted. A slider is formed of synthetic resin, and the slider is attached to the tip of the lever by fitting a pair of pin covers to the pins protruding from both sides of the lever, and each pin cover of the slider is vertically opposed to each other. A feature is that the guides are slidably fitted in a state of surface contact between the guides.

Next, an embodiment of the present invention will be described with reference to FIGS. 4 to 11.

FIG. 4 is a sectional view of the sliding part of an automobile door mirror constructed by applying the present invention to the conventional device described above.

The slider 13 includes a pair of pin covers 13a and 13b that fit and hold the pin 11d;
Connect the above pair of pin covers and lever 1
A member 13c that fits and holds the distal end of 1a so as to be rotatable is integrally formed of synthetic resin. That is, as shown in FIG. 11, the pin covers 13a and 13b have a cylindrical inner surface that can fit closely with the pin 11d, and a portion beyond the semicircumference of the pin cover 11d. The member 13c that connects the pin covers 13a and 13b has a recess 13d in which the tip of the lever 11a can be gently inserted and the lever 11a can rotate slightly around the pin 11d. Furthermore, the thickness of the pin covers 13a and 13b is made approximately equal to the distance between the guides 2a and 2b and the distance between the guides 2c and 2d.

The slider 13 configured as described above is attached to the tip of the lever 11a. Specifically, a pair of pin covers 13a and 13b are forcibly fitted on both sides of the pin 11d, respectively. Along with this, connection member 1
3c is naturally attached to the tip of the lever 11a.
In this state, the pin 11d with the pin covers 13a and 13b fitted thereon is fitted between the guides 2a and 2b and between the guides 2c and 2d.

In FIG. 11, 2a and 2b indicated by imaginary lines are the aforementioned guide surfaces. In this way, pin 11d
does not directly contact the guides 2a, 2b, and the pin covers 13b, 13 do not contact the guides 2b, 2d).
The pin covers _13b , ₁ are in surface contact with the guides 2a, 2c through the bottom surfaces 13b -1, 13a -1 of the guides 2a, 2c.
Edge surfaces 13b _-2 , 13a _-2 and 13 of 3a
