Abstract

There is provided an image projection system for use with a light post disposed adjacent a thoroughfare. The image projection system includes a projection device configured to project an image for observation by a viewer on the thoroughfare. A projection device support member is connected to the projection device and is also connectable to the light post. The image projection system also includes a display screen moveable between a deployed configuration and a stowed configuration. The display screen is disposed for observation by the viewer and in optical communication with the projection device to display the image projected by the projection device when in the deployed configuration. The display screen is withdrawn from view by the viewer when the display screen is in the stowed configuration. A display screen support member is connected to the display screen and is also connectable to the light post.

Claims

1. An image projection system for use with a light post disposed adjacent a thoroughfare, the light post having a light post shaft and a light source connected to the light post shaft, the light post shaft being connected to a foundation, the image projection system comprising:

a projection device configured to project an image for observation by a viewer on the thoroughfare;

a projection device support member connected to the projection device and connectable to the light post shaft;

a display screen being moveable between a deployed configuration and a stowed configuration, the display screen being exposed for observation by the viewer and in optical communication with the projection device to display the image projected by the projection device when in the deployed configuration, the display screen being withdrawn from view by the viewer when in the stowed configuration; and

a display screen support member connected to the display screen and connectable to the light post shaft.

2. The image projection system as recited in claim 1 wherein the display screen support member is sized and configured to dispose the display screen above the light post when the display screen is in the deployed position.

3. The image projection system as recited in claim 1 wherein the display screen is formed of a flexible material.

4. The image projection system as recited in claim 1 wherein the display screen is biased toward the stowed configuration.

5. The image projection system as recited in claim 1 wherein the display screen support member includes a screen stowing element configured to collect the display screen as the display screen moves toward the stowed configuration.

6. The image projection system as recited in claim 5 wherein the screen stowing element includes a rod being rotatable, the display screen moving between the stowed configuration and the deployed configuration as the rod rotates.

7. The image projection system as recited in claim 6 wherein the rod rotates in a first direction to move the display screen toward the deployed configuration and in a second direction to move the display screen toward the stowed configuration.

8. The image projection system as recited in claim 7 wherein the rod is biased toward the second direction.

9. The image projection system as recited in claim 1 wherein the image projected by the projection device is a static image.

10. The image projection system as recited in claim 1 wherein the image projected by the projection device is a dynamic image.

11. An image projection system for use with a light post disposed adjacent a thoroughfare, the light post having a light post shaft and a light source connected to the light post shaft, the light post shaft being connected to a foundation, the image projection system comprising:

a first projection device configured to project a first image for observation by a viewer on the thoroughfare, the first projection device being connectable to the light post shaft;

a second projection device configured to project a second image for observation by a viewer on the thoroughfare, the second projection device being connectable to the light post shaft;

a first display screen being moveable between a deployed configuration and a stowed configuration, the first display screen being exposed for observation by the viewer and in optical communication with the first projection device to display the image projected by the first projection device when in the deployed configuration, the first display screen being withdrawn from view by the viewer when in the stowed configuration;

a first display screen support member connected to the first display screen and connectable to the light post shaft, the first display screen support member being sized and configured to dispose the first display screen above the light post when the first display screen is in the deployed position;

a second display screen being moveable between a deployed configuration and a stowed configuration, the second display screen being exposed for observation by the viewer and in optical communication with the second projection device to display the image projected by the second projection device when in the deployed configuration, the second display screen being withdrawn from view by the viewer when in the stowed configuration; and

a second display screen support member connected to the second display screen and connectable to the light post shaft, the second display screen support member being sized and configured to dispose the second display screen above the light post when the first display screen is in the deployed position.

12. The image projection system as recited in claim 11 wherein the first and second display screens are arranged in a v-shaped configuration.

13. The image projection system as recited in claim 11 wherein the first display screen support member includes a first screen stowing element configured to collect the first display screen as the first display screen moves toward the stowed configuration.

14. The image projection system as recited in claim 13 wherein the second display screen support member includes a second screen stowing element configured to collect the second display screen as the second display screen moves toward the stowed configuration.

15. The image projection system as recited in claim 11 wherein the first display screen is biased toward the stowed configuration.

16. The image projection system as recited in claim 15 wherein the second display screen is biased toward the stowed configuration.

17. A method of displaying an image adjacent a light post disposed adjacent a thoroughfare, the light post having a light post shaft and a light source connected to the light post shaft, the light post shaft being connected to a foundation, the method comprising the steps of:

(a) providing a projection device and a display screen, the projection device configured to project an image for observation by a viewer on the thoroughfare, the display screen configured to display the image projected by the projection device, the display screen being moveable between a deployed configuration and a stowed configuration;

(b) connecting the projection device to the light post shaft; and

(c) connecting the display screen to the light post shaft, the display screen being positioned to be exposed for observation by a viewer and in optical communication with the projection device to display the image projected by the projection device when in the deployed configuration, the display screen being withdrawn from view by the view when in the stowed configuration.

18. The method as recited in claim 17 wherein step (a) includes providing a display screen formed of a flexible material.

19. The method as recited in claim 17 wherein step (a) includes providing a display screen that is biased toward the stowed configuration.

20. The image projection system as recited in claim 17 wherein step (a) includes providing a projection device configured to project a dynamic image.
