Abstract
Abstract A turn signal indicating system for a vehicle wherein a rotary and a stationary polarized sheet are mounted with respect to an end of a vehicle, along with a light source. A light intercepting sheet having a pattern of embossed lines formed thereon is disposed in the path of the light between the polarized sheets so that, upon rotation of the rotary sheet, traveling shadows are produced which give the illusion of linear motion in the direction to be turned.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
In combination, a motor vehicle including a body having at least one open face; and a turn signal unit mounted on said vehicle, said turn signal unit comprising a polarized sheet rotatably mounted on said body, drive means mounted on said body for rotating said polarized sheet, a source of light mounted on said body and directed towards said polarized sheet, control means on said vehicle for controlling the energization of said drive means and light source, reflecting means mounted on said body for reflecting the light from said source passing through said polarized sheet in a direction longitudinally of said vehicle and through said open face, means mounted on said body for defining at least one light intercepting pattern of motion lines extending across said open face and intercepting the reflected light from said reflecting means, and means for polarizing said reflected light, said pattern of motion lines being oriented relative to said reflecting means and said polarizing means to produce shadows traveling laterally with respect to said vehicle and in a single direction to indicate the particular direction of turn.
Claim 2
Dependent Claim
182 words
In combination, a motor vehicle including a body having at least one open face; and a turn signal unit mounted on said vehicle, said turn signal unit comprising a polarized sheet rotatably mounted on said body, drive means mounted on said body for rotating said polarized sheet, a source of light mounted on said body and directed towards said polarized sheet, control means on said vehicle for controlling the energization of said drive means and light source, reflecting means mounted on said body for reflecting the light from said source passing through said polarized sheet in a direction longitudinally of said vehicle and through said open face, means mounted on said body for defining at least one light intercepting pattern of motion lines extending across said open face and intercepting the reflected light from said reflecting means, and means for polarizing said reflected light, said pattern of motion lines being oriented relative to said reflecting means and said polarizing means to produce shadows traveling laterally with respect to said vehicle and in a single direction to indicate the particular direction of turn.
Claim 3
Dependent Claim
25 words
The combination of claim 1 wherein said means for defining said pattern of motion lines comprises a light intercepting sheet extending across said open face.
Claim 4
Dependent Claim
32 words
The combination of claim 2 further comprising a light transmitting member extending across said open face in a spaced relation to said reflecting means and in the path of said reflected light.
Claim 5
Dependent Claim
24 words
The combination of claim 3 wherein said polarizing means is in the form of a stationary polarized sheet disposed adjacent said light intercepting sheet.
Claim 6
Dependent Claim
32 words
The combination of claim 4 wherein said light intercepting sheet, said stationary polarized sheet, and said light transmitting member are all bonded together by a transparent adhesive to form a laminated unit.
Claim 7
Dependent Claim
43 words
The combination of claim 1 wherein said light source and said polarized sheet are mounted relative to said body in a manner so that the light passing through said polarized sheet is directed at an angle to the longitudinal axis of said vehicle.
Claim 8
Dependent Claim
27 words
The combination of claim 1 wherein said reflecting means is adapted to reflect said light in a direction away from said polarized sheet and said light source.
Claim 9
Dependent Claim
30 words
The combination of claim 1 further comprising a light transmitting layer having a figure thereon disposed in the path of said light in a position to be illuminated and animated.
Claim 10
Dependent Claim
39 words
The combination of claim 8 wherein said figure is an arrow pointing in the direction to be turned, and wherein said traveling shadows produce an illusion of animated linear motion of said arrow in the direction to be turned.
