Abstract

An adjustable wide angle inside rear view mirror includes a stationary central mirror and a pair of extensible side mirrors which can be pulled out so that the driver has a view of other vehicles in the "blind spots" on either side of a conventional rear view mirror. The side mirrors are interconnected so that both side mirrors are extended when either one of the side mirrors is extended manually. The extension of the side mirrors is continuously adjustable, but the amount of travel is limited so that the side mirrors can be pulled out only about three-quarters of their length. The wide angle rear view mirror can be retracted to permit the driver to adjust the position of the car'"'"'s sun visors, and then reextended.

Claims

1. An adjustable wide angle inside rear view mirror including:

a) a stationary central reflective element; and

b) a first and a second extensible side reflective element, the side reflective elements being interconnected so that both side reflective elements are extended when either one of the side reflective elements is extended manually, the extension of the side reflective elements being continuously adjustable.

2. An inside rear view mirror according to claim 1 in which the extensible reflective elements are interconnected by a plurality of flexible cords.

3. An inside rear view mirror according to claim 2 in which each cord extends from the second extensible reflective element, through a first aperture in the stationary reflective element, through a first and a second aperture in the first extensible reflective element, back through a second aperture in the stationary reflective element, and to the second extensible reflective element.

4. An inside rear view mirror according to claim 3, in which each reflective element is generally rectangular and has a pair of ends, the extensible reflective elements each having an inner end and an outer end, the first and second apertures in the stationary reflective element being positioned proximate respective ends of the stationary reflective element, the first and second apertures in the first extensible reflective element being positioned proximate the outer end of the first extensible reflective element.

5. An inside rear view mirror according to claim 4 further comprising a box-like frame, the frame having a plurality of parallel upper and lower grooves for receiving the reflective elements.

6. An inside rear view mirror according to claim 5 in which a plurality of parallel upper grooves comprise a front, a middle and a rear groove, the plurality of parallel lower grooves comprising a front, a middle and a rear respective groove, the stationary reflective element being fixedly mounted in the middle grooves, and the front and rear reflective elements being movably mounted in the front and rear respective grooves.

7. An inside rear view mirror according to claim 6 further comprising means for limiting the outermost extension of the extensible reflective elements.

8. An inside rear view mirror according to claim 1 wherein each reflective element comprises a mirror and a mirror mounting element.

9. An inside rear view mirror according to claim 5 wherein the box-like frame include a generally planar back, the grooves being formed an angle of about 10 to 15 degrees to the back.

10. An inside rear view mirror according to claim 1 further comprising mounting means for attaching the inside wide angle rear view mirror to an existing rear view mirror.

11. An adjustable wide angle inside rear view mirror including:

a) a stationary central reflective element;

b) a first and a second extensible side reflective element, the side reflective elements being interconnected so that both side reflective elements are extended when either one of the side reflective elements is extended manually, the extension of the side reflective elements being continuously adjustable;

c) a box-like frame, the frame having a plurality of parallel upper and lower grooves for receiving the reflective elements; and

d) means for limiting the outermost extension of the extensible reflective elements.
