Abstract

A visual communicator for a rear window of a vehicle. The communicator is semi-transparent and adapted to be disposed in the rear window of the vehicle for viewing from outside of the vehicle. The degree of transparency is such as to accommodate normal use of an inside rearview mirror of the vehicle by a driver of the vehicle. The communicator also includes a message display unit including a plurality of light emitting diodes comprising in a matrix arrangement and disposed in a limited discrete portion of the rear window. The light emitting diodes are selectively energizable to emit light in the form of a message. The communicator further includes a message control unit operationally interconnected to the light emitting diodes for selectively energizing the light emitting diodes. The message control unit is programmed to energize the light emitting diodes in any one of a plurality of preselected patterns. With this arrangement, the preselected patterns form messages for viewing from outside of the vehicle upon selective actuation of the message control unit.

Claims

a message display unit including a plurality of light emitting diodes arranged in a matrix, said light emitting diodes comprising at least a portion of semi-transparent means and being selectively energizable to emit light, said matrix being disposed in a limited discrete portion of said rear window;

a message control unit for selectively energizing said light emitting diodes, said message control unit being operationally interconnected to said light emitting diodes and being programmed to energize said light emitting diodes in any one of a plurality of preselected patterns, said preselected patterns forming messages for viewing from outside of said vehicle; and

means for selectively actuating said message control unit.

2. The visual communicator as defined by claim 1 wherein said semi-transparent means also comprises a window screen formed of a semi-transparent material and including means for mounting said window screen in said rear window of said vehicle, said light emitting diodes being supported by said window screen.

3. The visual communicator as defined by claim 2 wherein said means for mounting said window screen in said rear window of said vehicle is an adjustable frame, said frame being dimensionally adjustable to substantially conform to the periphery of said rear window of said vehicle.

4. The visual communicator as defined by claim 3 wherein said window screen is sized to overlap said frame in a position of maximum dimensional adjustment, said window screen being trimmable to substantially conform dimensionally to the periphery of said frame after adjustment.

5. The visual communicator as defined by claim 4 including means for securing said window screen to the periphery of said frame after trimming.

6. The visual communicator as defined by claim 5 wherein said adjustable frame is comprised of at least four tubular members adapted to be secured in a generally rectangular configuration, said window screen also having a generally rectangular configuration dimensioned to overlap each of said tubular members of said frame.

7. The visual communicator as defined by claim 6 wherein said tubular members are generally square in cross section and including a connector member for joining adjacent ends of said tubular members.

8. The visual communicator as defined by claim 7 wherein each of said connector members includes a first portion adapted for insertion into one of said tubular members and a second portion adapted for insertion into the next adjacent of said tubular members.

9. The visual communicator as defined by claim 8 including hinge means joining said first and second portions of each of said connector members for assembly of said adjustable frame, said hinge means accommodating pivotal movement of one of said tubular members relative to the next adjacent of said tubular members to form a right angle during assembly of said adjustable frame, said hinge means being rendered inoperative after assembly of said adjustable frame.

10. The visual communicator as defined by claim 6 wherein said means for securing said window screen to the periphery of said frame includes a plurality of screen retaining caps, said caps being adapted to securely retain said window screen in substantially conforming overlapping relation to at least three of said tubular members of said adjustable frame.

11. The visual communicator as defined by claim 10 wherein said window screen includes a pocket along one edge adapted to receive one of said tubular members of said adjustable frame, said message display unit being disposed adjacent said pocket, said caps being adapted to securely retain the other three edges of said window screen in substantially conforming overlapping relation to the other three of said tubular members of said adjustable frame.

12. The visual communicator as defined by claim 11 wherein said message control unit is operationally interconnected to said light emitting diodes by means of electrical wires, said electrical wires extending from said light emitting diodes to said message control unit through a second pocket in said window screen, said second pocket extending along said window screen between said light emitting diodes and said pocket adapted to receive one of said tubular members.

13. The visual communicator as defined by claim 11 wherein at least said tubular members to be overlapped by edges of said window screen each have a pair of longitudinally extending projections on oppositely facing parallel surfaces thereof, each of said caps being in the form of a longitudinally extending channel defined by a pair of parallel walls joined along corresponding edges thereof by a top wall, said channels each having a pair of longitudinally extending indentations to cooperate with the corresponding pairs of longitudinally extending projections on inwardly facing parallel walls thereof.

14. The visual communicator as defined by claim 13 wherein said trimmable edges of said window screen are trimmable to overlap said pairs of longitudianally extending projections on said oppositely facing parallel surfaces of said tubular members, each of said caps being adapted to be pressed onto one of said tubular members after said trimmable edges of said window screen have been made to overlap said pairs of longitudinally extending projections, said pairs of longitudinally extending indentations on said inwardly facing parallel walls of said channels cooperating with said pairs of longitudinally extending projections on said oppositely facing parallel walls of said tubular members to securely retain said window screen in substantially conforming overlapping relation to said tubular members.

15. The visual communicator as defined by claim 6 wherein each of said tubular members includes a plurality of break points adjacent at least one end thereof, said break points facilitating adjustment of said frame to substantially conform to the periphery of said rear window of said vehicle.

16. The visual communicator as defined by claim 15 wherein said tubular members are generally square in cross section and including a connector member for joining adjacent ends of said tubular members.

17. The visual communicator as defined by claim 16 wherein each of said connector members includes a first portion adapted for insertion into one of said tubular members and a second portion adapted for insertion into the next adjacent of said tubular members.

18. The visual communicator as defined by claim 17 including hinge means joining said first and second portions of each of said connector members for assembly of said adjustable frame, said hinge means accommodating pivotal movement of one of said tubular members relative to the next adjacent of said tubular members to form a right angle during assembly of said adjustable frame, said hinge means being rendered inoperative after assembly of said adjustable frame.

19. The visual communicator as defined by claim 18 wherein said means for securing said window screen to the periphery of said frame includes a plurality of screen retaining caps, said caps being adapted to securely retain said window screen in substantially conforming overlapping relation to at least three of said tubular members of said adjustable frame.

20.
