Abstract
Abstract A convex mirror has a frosted non-reflective elongated and horizontal line, approximately midway of the mirror and of a width less than the thickness of the mirror, and a light source is disposed adjacent the reflective surface with a colored filter positioned between the light source and the frosted line whereby a predetermined safe distance is indicated for changing lanes into a position in front of the immediately passed vehicle. In another mirror, safe turning distances are indicated by predetermined lines extending vertically of the convex mirror.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
A distance indicating mirror device for attachment to a passing vehicle comprising a convex mirror for reflecting an image of a passed vehicle, a housing for supporting said mirror, said housing having a chamber therein partially defined by the reflective surface portion of said mirror, and indicia means on said mirror and viewable outwardly of said mirror for indicating a predetermined safe distance between a passing and a passed vehicle whereby a passing vehicle may relatively safely pull over in front of an immediately passed vehicle, said indicia means including a non-reflective surface portion of the otherwise reflective surface of said mirror located at a light transmitting predetermined horizontal position on said mirror when attached to a passing vehicle above which the image of a passed vehicle will be reflected when said predetermined safe distance is achieved, illuminating means disposed within said chamber for emitting light, and a colored filter between said non-reflective surface portion and said illuminating means for passing colored light through said non-reflective surface portion of said mirror.
Claim 2
Dependent Claim
171 words
A distance indicating mirror device for attachment to a passing vehicle comprising a convex mirror for reflecting an image of a passed vehicle, a housing for supporting said mirror, said housing having a chamber therein partially defined by the reflective surface portion of said mirror, and indicia means on said mirror and viewable outwardly of said mirror for indicating a predetermined safe distance between a passing and a passed vehicle whereby a passing vehicle may relatively safely pull over in front of an immediately passed vehicle, said indicia means including a non-reflective surface portion of the otherwise reflective surface of said mirror located at a light transmitting predetermined horizontal position on said mirror when attached to a passing vehicle above which the image of a passed vehicle will be reflected when said predetermined safe distance is achieved, illuminating means disposed within said chamber for emitting light, and a colored filter between said non-reflective surface portion and said illuminating means for passing colored light through said non-reflective surface portion of said mirror.
Claim 3
Dependent Claim
15 words
In the device as defined in claim 1 wherein said non-reflective surface portion is frosted.
Claim 4
Dependent Claim
28 words
In the device as defined in claim 1 further comprising reflector means disposed between said housing and illuminating means for directing the light through said non-reflective surface portion.
Claim 5
Dependent Claim
76 words
In the device as defined in claim 1 further comprising a universal mounting means for said housing to adjustably position said mirror with respect to a driver of a passing vehicle, said illuminating means including a bulb within said chamber and electrical wiring means extending through said universal mounting means into said chamber and being electrically coupled to said bulb, said wiring means being adapted for connection to an electrical energy source of a passing vehicle.
Claim 6
Dependent Claim
36 words
In the device as defined in claim 4 wherein said illuminating means includes a receptacle rigidly mounted with respect to said housing, said receptacle receiving said bulb and being electrically connected to said electrical wiring means.
Claim 7
Dependent Claim
41 words
In the device as defined in claim 1 wherein said non-reflective surface portion is of a predetermined width interrupting the reflective surface of said mirror, said mirror having a thickness greater than said predetermined width to minimize spurious reflections and refractions.
Claim 8
Dependent Claim
15 words
In the device as defined in claim 6 wherein said non-reflective surface portion is frosted.
Claim 9
Dependent Claim
20 words
In the device as defined in claim 1 wherein said non-reflective surface portion is disposed approximately midway of said mirror.
Claim 10
Dependent Claim
40 words
In the device as defined in claim 1 wherein said indicia means further includes generally vertical and spaced light transmitting non-reflective portions to denote proper turning clearances around a corner for a passing vehicle to which said device is attached.
