Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of an auxiliary rear-view mirror disclosed in Japanese Utility Model Application No. 52-116848, which is used to be attached to an existing rear-view mirror inside an automobile.

[Conventional technology]

The above-mentioned conventional auxiliary room mirror has a downward fixed hanging jaw on the left and right sides of the upper side of the mirror frame, and an upward movable hanging jaw opposite to the fixed hanging jaw on the lower left and right sides of the mirror frame. The rod spring is loosely inserted into the spring bearing shaft between the left and right hanging jaws, and the spring rods at both ends are in elastic contact with each other. The left and right sides of the upper and lower sides of the auxiliary rearview mirror are elastically sandwiched, and the auxiliary rearview mirror is attached and held to the existing rearview mirror.

[The problem that the idea aims to solve]

In the auxiliary room mirror described in the above conventional technology, the movable hanging jaws on the left and right sides are composed of left and right integral parts, so the movable hanging jaws on the left and right sides always move together as one unit, so that the following There's a problem.

That is, as shown in Fig. 5A, the auxiliary room mirror A
When installing the auxiliary rearview mirror A in the middle of the existing rearview mirror as shown in the figure, if the auxiliary rearview mirror A is installed in the middle of the existing rearview mirror as shown in the figure, the movable hanging jaws on the left and right sides There is no problem because the fixed hanging jaw and the fixed hanging jaw equally hold the upper and lower sides of the left and right sides of the existing rearview mirror with the same width as the border, but if the auxiliary rearview mirror is moved to one side as shown in Figure 5B, If you shift it to the desired position for easy viewing, only the movable hanging jaw on one side (the one on the left side in the figure) located in the wide part of the existing rearview mirror will have a clamping effect, but the other side located in the narrow part will have a clamping effect. The movable hanging jaw (the one on the right in the figure) is in a floating state and does not perform any clamping action at all, even though the clamping force is applied by the bar spring. There is one place that should be securely clamped.
Since it is in a so-called cantilevered state, the mounting condition is inevitably unstable, and there is a risk that the auxiliary rearview mirror may shake due to vibrations of the car or may fall off.

Therefore, this invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to separate the left and right movable hanging jaws into left and right so that they can each move independently. The independent movement of the left and right sides allows the left and right movable jaws to always follow the shape of the bottom of the existing rearview mirror, even when the auxiliary rearview mirror is moved to one side in order to be easily seen. The purpose is to enable secure installation in this misaligned position, and to eliminate concerns such as the auxiliary rearview mirror shaking or falling off due to vibrations caused by automobile driving. .

[Means to solve the problem]

The structure of the present invention to achieve the above object includes downward fixed hanging jaws that protrude rearward on the left and right sides of the upper side of the mirror frame, and upward facing fixed hanging jaws that oppose the fixed hanging jaws on the left and right sides of the lower side of the mirror frame. In an auxiliary room mirror of a type in which a movable hanging jaw is provided, and the center portion of the left and right movable hanging jaws is engaged with the spring rod portions at both ends of a bar spring that is loosely inserted and wound around a spring bearing shaft between the left and right hanging jaws, The side movable hanging jaws are separated to the left and right so that they can be independently moved up and down with respect to the mirror frame, and the separated left and right movable hanging jaws are engaged with one end of each of the spring rod parts. This article focuses on an auxiliary rearview mirror for automobiles.

〔Example〕

First, details of the embodiment will be described with reference to the drawings.

A is an auxiliary room mirror, and this auxiliary room mirror A has downward fixed hanging jaws 3 that protrude rearward of the mirror frame 2 on the left and right sides of the upper side of the mirror frame 2 on which the mirror 1 is stretched on the front side. An upward movable hanging jaw 4 facing the fixed hanging jaw 3 is provided on each side, and the movable hanging jaw 4 is elastically biased toward the fixed hanging jaw 3 by a spring means.

The spring means is formed by winding the central part of one bar spring 5 so as to have a spring pressure, and this winding part 5a is attached to a spring receiver which is protruded from the mirror frame part between the left and right hanging jaws. The rod spring 5 is loosely inserted into the shaft 6, and the spring rod portions 5b at both ends of the bar spring 5 are engaged with the left and right movable hooks 4, respectively.

Therefore, the main structure of the present invention is to separate the left and right movable hanging jaws 4 so that they can each move independently relative to the lens frame, and to attach one end of the spring rod portion 5b to each of the separated left and right hanging jaws 4. It is engaged.

The separated left and right movable hanging jaws 4 are attached to individual actuation plates 4a, and each actuation plate 4a has a guide pin 1a and an actuation plate provided on the inner wall surface of the mirror frame 2 facing the mirror 1. 4a is engaged with the elongated hole 4b so as to be slidable up and down, and a spring hook portion 4c is bent at the upper end of the actuating plate 4a, and the spring rod of the rod spring 5 is attached to the spring hook portion 4c. The portion 5b is slidably engaged. In addition, the actuating plate 4a
The upper end is a stopper 1 for regulating the rise provided on the lens frame 2.
I am facing b.

[Effect of invention]

In order to attach the auxiliary room mirror A configured as described above to the existing room mirror B, the upper and lower sides of the existing room mirror B are pressed against the elasticity of the bar spring between the movable hanging jaw 4 and the fixed hanging jaw 3. The auxiliary room mirror A is attached and held to the existing room mirror B by being held between the two.

[Effect of idea]

As described above, according to the present invention, the left and right movable hanging jaws provided on the auxiliary rearview mirror are separated so that they can each move independently relative to the mirror frame, and by the independent movement caused by this separation, In order to make it easier to see the auxiliary rearview mirror, even if it is installed shifted to one side, the movable hanging jaws on the left and right sides and the fixed hanging jaws opposing it will cause the upper and lower sides of the existing rearview mirror in the above-mentioned misaligned positions to be fixed. It can be held elastically and reliably at two points.

In addition, the above-mentioned reliable clamping action stabilizes the auxiliary rearview mirror, thereby eliminating concerns such as the rearview mirror shaking or falling off due to vehicle vibrations, which has not been possible with conventional auxiliary rearview mirrors of this type. This has unexpectedly excellent practical effects.
