Abstract
Abstract This disclosure relates to a frame for automobile rearview mirrors which is constructed and arranged for the removal of moisture from the face of a mirror mounted in the frame. The frame is so constructed that when air impinges thereon, a region of low pressure is established along one or more edges thereof. Moisture on the face of the mirror will then move across the face of the mirror toward the region of low pressure and will be removed from the face of the mirror.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
A support frame for an automobile rearview mirror adapted to be mounted to the outside of the automobile, said frame having means for mounting a mirror thereon, the periphery of said frame including at least one margin portion extending no further than the front surface of a mirror mounted to said frame, the back of said frame behind said margin portion having a first surface disposed at an acute angle to a first vertical plane and a second surface disposed at an acute angle to a second plane perpendicular to the first plane, a first curvature joining said first and second surfaces, said second surface extending to said peripheral portion at a second curvature so that when air impinges on the back of said frame behind said margin portion, it is directed past said margin portion at an increased velocity and reduced pressure with respect to the remainder of the periphery of said frame.
Claim 2
Dependent Claim
154 words
A support frame for an automobile rearview mirror adapted to be mounted to the outside of the automobile, said frame having means for mounting a mirror thereon, the periphery of said frame including at least one margin portion extending no further than the front surface of a mirror mounted to said frame, the back of said frame behind said margin portion having a first surface disposed at an acute angle to a first vertical plane and a second surface disposed at an acute angle to a second plane perpendicular to the first plane, a first curvature joining said first and second surfaces, said second surface extending to said peripheral portion at a second curvature so that when air impinges on the back of said frame behind said margin portion, it is directed past said margin portion at an increased velocity and reduced pressure with respect to the remainder of the periphery of said frame.
Claim 3
Dependent Claim
17 words
The frame of claim 1 wherein said peripheral portion is at the lower portion of said frame.
Claim 4
Dependent Claim
44 words
The frame of claim 1 wherein said frame is so formed that the first surface is disposed at an angle no less than 10* to the first vertical plane and the second surface is disposed at an angle of 20*-40* with the second plane.
Claim 5
Dependent Claim
16 words
The frame of claim 3 wherein said first curvature is no less than 3/8 -inch radius.
Claim 6
Dependent Claim
16 words
The frame of claim 3 wherein said second curvature is no less than 1/8 -inch radius.
Claim 7
Dependent Claim
23 words
The frame of claim 3 wherein the periphery of said frame is generally rectangular and said margin portion extends along the bottom thereof.
Claim 8
Dependent Claim
33 words
The frame of claim 3 wherein the periphery of said frame is generally rectangular and said frame has two of said margin portions, said margin portions being at opposite sides of said frame.
Claim 9
Dependent Claim
46 words
The frame of claim 1 wherein said margin portion defines a seat for an edge of the mirror and said edge of the mirror is received in said seat with the front surface of said margin extending no further than the front surface of the mirror.

The frame of claim 1 wherein said margin abuts the rear surface of the mirror.
Claim 11
Dependent Claim
33 words
The frame of claim 1 wherein the distance between the face of the mirror and the rear of said margin is no greater than one-fourth inch at the extreme edge of said margin.
Claim 12
Dependent Claim
33 words
The frame of claim 3 wherein the distance between the fAce of the mirror and the rear of said margin is no greater than one-fourth inch at the extreme edge of said margin.
Claim 13
Dependent Claim
22 words
The frame of claim 1 further including a mirror mounted therein wherein said mirror has two viewing surfaces on an integral body.
