Abstract
Abstract A flashing reflector system in which at least one retroreflective reflector having at least one wide angle area thereon is mounted on one side of a revolvable wheel member. When this assembly is revolved, a characteristic, highly visible flashing of retro-reflected light is produced which is visible over wide side angles relative to the revolving wheel member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
202 words
An assembly for producing a light flashing effect comprising in combination A. a rotatable wheel member having a wheel axis, B. a reflector unit having at least one region comprised of transparent solid material and having a region axis normal thereto, said region having formed therein a group of cube corner reflector elements, such elements each having a central optical axis, each respective such optical axis being both disposed substantially parallel to the respective such optical axes of the other such elements in said group, and inclined at a predetermined angle relative to said region axis, said region being retroreflective of light directed thereon at least over an angle of from about 20* to 70* relative to said region axis in the direction of said predetermined angle, C. mounting means to mount said reflector fixedly to a side portion of said wheel member, D. said wheel member, said reflector and said mounting means coacting together so that, when said wheel is rotated, said reflector is adapted to retro-reflect light intermittently so as to produce a flashing light signal viewable within a viewing angle of at least about 20* to 70* relative to said wheel axis once during each 360* of wheel rotation.
Claim 2
Dependent Claim
202 words
An assembly for producing a light flashing effect comprising in combination A. a rotatable wheel member having a wheel axis, B. a reflector unit having at least one region comprised of transparent solid material and having a region axis normal thereto, said region having formed therein a group of cube corner reflector elements, such elements each having a central optical axis, each respective such optical axis being both disposed substantially parallel to the respective such optical axes of the other such elements in said group, and inclined at a predetermined angle relative to said region axis, said region being retroreflective of light directed thereon at least over an angle of from about 20* to 70* relative to said region axis in the direction of said predetermined angle, C. mounting means to mount said reflector fixedly to a side portion of said wheel member, D. said wheel member, said reflector and said mounting means coacting together so that, when said wheel is rotated, said reflector is adapted to retro-reflect light intermittently so as to produce a flashing light signal viewable within a viewing angle of at least about 20* to 70* relative to said wheel axis once during each 360* of wheel rotation.
Claim 3
Dependent Claim
202 words
An assembly for producing a light flashing effect comprising in combination A. a rotatable wheel member having a wheel axis, B. a reflector unit having at least one region comprised of transparent solid material and having a region axis normal thereto, said region having formed therein a group of cube corner reflector elements, such elements each having a central optical axis, each respective such optical axis being both disposed substantially parallel to the respective such optical axes of the other such elements in said group, and inclined at a predetermined angle relative to said region axis, said region being retroreflective of light directed thereon at least over an angle of from about 20* to 70* relative to said region axis in the direction of said predetermined angle, C. mounting means to mount said reflector fixedly to a side portion of said wheel member, D. said wheel member, said reflector and said mounting means coacting together so that, when said wheel is rotated, said reflector is adapted to retro-reflect light intermittently so as to produce a flashing light signal viewable within a viewing angle of at least about 20* to 70* relative to said wheel axis once during each 360* of wheel rotation.
Claim 4
Dependent Claim
202 words
An assembly for producing a light flashing effect comprising in combination A. a rotatable wheel member having a wheel axis, B. a reflector unit having at least one region comprised of transparent solid material and having a region axis normal thereto, said region having formed therein a group of cube corner reflector elements, such elements each having a central optical axis, each respective such optical axis being both disposed substantially parallel to the respective such optical axes of the other such elements in said group, and inclined at a predetermined angle relative to said region axis, said region being retroreflective of light directed thereon at least over an angle of from about 20* to 70* relative to said region axis in the direction of said predetermined angle, C. mounting means to mount said reflector fixedly to a side portion of said wheel member, D. said wheel member, said reflector and said mounting means coacting together so that, when said wheel is rotated, said reflector is adapted to retro-reflect light intermittently so as to produce a flashing light signal viewable within a viewing angle of at least about 20* to 70* relative to said wheel axis once during each 360* of wheel rotation.
Claim 5
Dependent Claim
76 words
The assembly of claim 1 wherein said reflector contains two such regions, said wheel member; said reflector and said mounting means coacting together so that, when said wheel is rotated, said reflector is adapted to retro-reflect light intermittently so as to produce two flashing light signals, each one of said signals being viewable within a viewing angle of at least about 20* to 70* relative to said wheel axis once during each 360* of wheel rotation.
Claim 6
Dependent Claim
16 words
The assembly of claim 2 wherein the respective region axes are substantially parallel to each other.
Claim 7
Dependent Claim
99 words
The assembly of claim 3 wherein said reflector contains a third region, said third region being generally retro-reflective of light directed thereon at least over an angle of about 30* about its region axis, said area having a group of cube corner reflector elements formed therein, the respective optical axes of said reflector elements being disposed substantially parallel to its said region axes, all region axes of said reflector being substantially parallel to each other, said reflector having a combined zone Of reflectorization which is at least about 80* measured transversely in one direction relative to said region axes.
