Description

[Detailed Description of the Invention] The present invention relates to a holding device for an outside mirror of a large vehicle such as a truck.

As shown in Fig. 1, in the conventional model of this type, the back side of the mirror unit m is attached to the stay S attached to the side of the car body.
The assembly is fixed through.

The details of its assembly are as shown in Figures 2 and 3, with the first bracket b fixed to the back surface of the mirror unit m.
1 and both mounting pieces alt82 of the second bracket b2, which has a hollow space for clamping the stay S, are assembled using bolts C, and this bolt c is tightened by force on the bracket b1. b
The rotational holding force of the two comrades (rotational torque shown by the arrow A in the figure) and the clamping holding force of the stay S of the bracket b2 (the rotational torque shown by the arrow B in the figure)
The rotational torque (shown by ) is adjusted.

Note that p in the figure represents a resin spacer.

However, in the conventional structure as described above, the bracket b1
．． Since the rotational holding force (arrow A) between b2 cannot be made sufficiently large, the mirror may tilt against the stay unnecessarily, and the clamping force of the stay S by the bracket b2 cannot be adjusted as desired. This is extremely difficult.

In view of the above-mentioned points, the present invention aims to provide a retaining device for an automobile mirror that can easily adjust the clamping force of the stay and that can also securely attach the mirror to the bracket. .

In order to achieve the above-mentioned object, the present invention provides a tapered convex portion and a concave portion that can fit into each other on the mirror body and the mirror body joint side of the bracket, and on the side opposite to the tapered part of the bracket. An elastic holding part of the stay is provided, a stay holder is interposed between the elastic holding part and the bracket, and a bolt is passed through the mirror body, the flaket, and the stay holder through the tapered protrusion and recess, and The stay is inserted into the elastic clamping part of the bracket, and the clamping edge of the bracket to the stay and the pressure contact force between the tapered convex part and the concave part of the bracket and the mirror body can be adjusted by tightening the bolt. do.

Hereinafter, an embodiment of the automobile mirror holding device according to the present invention will be described with reference to FIGS. 4 to 6.

The mirror holding device in this embodiment is particularly used for the outside mirror of a large vehicle such as a truck, and includes a mirror body 1 that supports a mirror 11, and a vehicle body (
(not shown), a bolt 3, a bracket 4, a spring washer 5, and a flat washer 6.
, a holder connecting nut 7, and a stay presser 8.

The mirror body 1 is provided with a tapered convex portion 12 protruding outward, and the convex portion 12 has a through hole 13 in the center thereof for insertion of the bolt 3, and a stepped portion for engaging the head of the bolt 3. 14 is provided.

The bracket 4 is provided with a tapered recess 41 into which the tapered convex part 12 of the □ mirror body 1 can fit, on the side of the mirror body joint.
A through hole 42 through which the bolt 3 can be inserted is provided, and a small engagement groove 43 into which a rotation stopper projection 31 provided approximately in the middle of the bolt 3 can be engaged is provided. A substantially U-shaped elastic clamping portion 44 is provided on the opposite side to clamp the stay 2 in a direction perpendicular to the bolt 3.

The stay presser 8 has a semicircular stay pressing surface 8 on one end surface.
1, and a through hole 82 through which the bolt 3 can be inserted is provided approximately in the center.

Then, a stay presser 8 is interposed between the bracket 4 and its elastic clamping part 44, and a stay 2 is inserted between the elastic clamping part 44 and the stay clamp 8, and the mirror body 1
The bolt 3 is inserted into the through hole 13, the bracket 4, and the through hole 42°82 of the stay holder from the inside, and the holder connecting nut 7 is screwed onto the bolt 3.

Since the mirror holding device of the present invention has the above-mentioned configuration, tightening of the holder connecting nut 7 increases the clamping force of the elastic clamping portion 44 of the flaket 40 to the stay 2 and the clamping force of the bracket 4 to the stay 2.
The pressing force between the tapered concave portion of the mirror body 1 and the tapered convex portion 12 of the mirror body 1 can be adjusted.

That is, when the holder connecting nut 7 is tightened, the elastic clamping part 44 of the bracket 4 bends and clamps the stay, and the pressing surface 81 of the stay presser 8 presses the stay 2 against the elastic clamping part 44 of the bracket 40, causing the stay to tighten. The clamping force is made uniform, and thus the bracket 4 and the stay 2 are integrated.

Further, the tapered concave portion 41 of the bracket 4 fits into the tapered convex portion 12 of the mirror body 1, so that the bracket 4 and the mirror body 1 are integrated, and the mirror body 1 is fixed to the stay 2 via the bracket 4.

At this time, the small protrusion 31 of the bolt 3 engages with the small engagement groove 43 of the bracket 4 to stop the bolt 3 from rotating, so there is no risk that the threaded connection between the bolt 3 and the holder connecting nut 7 will loosen. do not have.

When the holder connecting nut 7 is loosened, the elastic clamping part 44 of the bracket 40 returns to its original state due to the elastic restoring force, and the clamping of the elastic clamping part 44 of the bracket 4 to the stay 2 is released.
Furthermore, the fitted state between the tapered recess 41 of the bracket 4 and the tapered protrusion 12 of the mirror body 1 is released, and the mirror body 1 can be tilted in the direction of the arrow C and arrow D in FIG.

7 and 8 are partial sectional views showing other embodiments of the present invention, in which the mirror body 1 is provided with a tapered concave portion 15, while the bracket 4 is provided with a tapered convex portion 45.
Fig. 8 shows a case in which a normal nut 71 is used in place of the holder connecting nut 7.

As described above, in the present invention, the clamping force of the bracket to the stay and the pressing force between the bracket and the mirror body can be adjusted by tightening the bolts. Since the force is made uniform, it is easy to adjust the tilt of the mirror body.

Furthermore, since the bracket and mirror body are assembled with the tapered concave portion and tapered convex portion fitted together, the mirror can be assembled securely and firmly without the mirror tilting unnecessarily relative to the stay as in the conventional case. .
