Irridescent drawing or sketching device

Claim 2

A sketching device for making an irridescent image comprising a housing having an upper member and a complementary lower member, said upper member having a window formed therein, a transparent imaging surface having disposed therein an irridescent dye, a sheet of opaque plastic material disposed below said imaging surface, said imaging surface and sheet of opaque material being disposed in interfacing relationship, an inner annular frame disposed between said upper and lower members in alignment with said window, means for securing said imaging surface and underlying opaque material to said inner frame, a courser disposed in contacting relationship with said sheet of opaque material for imparting a pressure thereon and actuating means for moving said courser along an X and Y axis either independently or simultaneously relative to said sheet of opaque material whereby the pressure applied by the courser as it is translated relative to said sheet develops an irridescent image at said imaging surface along the points of applied pressure, said actuating means including a pair of courser arms disposed at right angles to one another and crossing each other, each of said courser arms having elongated slot formed therein, and said courser being captive by said courser arms at the intersection thereof whereby said courser is guided along said slots as one or both of said courser arms is translated relative to said imaging sheet.

Claim 3

A sketching device as defined in claim 1 wherein said courser includes a courser body held captive by the intersecting slots if said courser arms, a courser tip projecting out from said courser and a spring for normally biasing said courser tip against said sheet of opaque material.

Claim 4

A sketching device as defined in claim 2 wherein said courser includes a bottom member connected to said body member, and said body member including an inturned flange to define an opening therein, and said courser tip projects beyond said opening.

Claim 5

A sketching device for making an irridescent image comprising a housing comprising an upper member and a lower base member, said upper member having a window opening formed therein, and a pair of elongated slots disposed normal to one another adjacent a corresponding edge of said window opening, an inner endless frame member disposed in alignment with said window opening between said upper member and said base member, a transparent imaging plate having an irridescent dye disposed therethrough, an opaque plastic sheet disposed in interfacing relationship to said imaging plate, means for securing said imaging plate and opaque sheet to said frame member whereby said imaging plate is disposed within said window opening, and said opaque sheet underlying said imaging plate, said inner frame member having a depending flange defining a guide rail extending along adjacent normally disposed edges thereof, said guide rails being disposed parallel relative to a corresponding elongated slot, a pair of courser arms crossing one another for movement along the X and Y axis of said imaging plate interposed between said inner frame member and said lower base member, each of said courser arms having an elongated slot formed therein, said slots being disposed in intersecting relationship, a courser means confined to said intersecting slots at the point of intersection, said courser means including a body portion that is retained at the intersection of said elongated, intersecting slots, each of said courser arms having an operating knob projecting upward through corresponding housing slot, a guide groove formed on each of said courser arms for receiving a corresponding depending guide rail of said inner frame member, said courser means including a body portion confined in the courser arm slots at the intersection thereof, a courser tip movably mounted in said body portion, a spring means for biasing said courser tip toward said opaque sheet, and an erasing means, said erasing means comprising a handle portion and connecting opposed depending flanges, an erasing strand extending between the opposed flanges of said handle, said erasing strand being disposed between said imaging plate and said opaque sheet whereby said strand effects separation between said imaging plate and opaque sheet at the point of contact therebetween to erase the irridescent image.

Claim 6

A sketching device for making an irridescent image comprising a housing comprising an upper member and a lower base member, said upper member having a window opening formed therein, and a pair of elongated slots disposed normal to one another adjacent a corresponding edge of said window opening, an inner endless frame member disposed in alignment with said window opening between said upper member and said base member, a transparent imaging plate having an irridescent dye disposed therethrough, an opaque plastic sheet disposed in interfacing relationship to said imaging plate, means for securing said imaging plate and opaque sheet to said frame member whereby said imaging plate is disposed within said window opening, and said opaque sheet underlying said imaging plate, said inner frame member having a depending flange defining a guide rail extending along adjacent normally disposed edges thereof, said guide rails being disposed parallel relative to a corresponding elongated slot, a pair of courser arms crossing one another for movement along the X and Y axis of said imaging plate interposed between said inner frame member and said lower base member, each of said courser arms having an elongated slot formed therein, said slots being disposed in intersecting relationship, a courser means confined to said intersecting slots at the point of intersection, said courser means including a body portion that is retained at the intersection of said elongated, intersecting slots, each of said courser arms having an operating knob projecting upward through corresponding housing slot, a guide groove formed on each of said courser arms for receiving a corresponding depending guide rail of said inner frame member, said courser means including a body portion confined in the courser arm slots at the intersection thereof, a courser tip movably mounted in said body portion, a spring means for biasing said courser tip toward said opaque sheet, and an erasing means, said erasing means comprising a handle portion and connecting opposed depending flanges, an erasing strand extending between the opposed flanges of said handle, said erasing strand being disposed between said imaging plate and said opaque sheet whereby said strand effects separation between said imaging plate and opaque sheet at the point of contact therebetween to erase the irridescent image.
