ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to activity units and, more specifically, to automobile activity screens. The present invention, the automobile activity screen, is designed to occupy children while traveling in an automobile. The activity screen of the present invention is mounted to an extension rod, such as those having spring tension, that attaches to the garment hooks located in the rear seat area of an automobile. There will be various models, each enthralling to the age group designed to occupy. Each screen will provide intriguing elements such as colorful screens for newborns adjusting eyesight, learning games such as letters of the alphabet and numbers. There will be screens that will teach time and screens that will teach hand and eye coordination.
There is also a screen with a chalkboard for children to practice writing or drawing. The chalkboard model provides a fold down eating tray or book rest. The activity screens will ride on an extension rod that is attached to the garment hooks located in the rear seating area of an automobile. The screen holder attaches to an extension rod, having an opening into which the activity screen slides. The screen holder is attached to one end of a connection member, which is pivotally connected to the activity screen on the other end. At the top of the screen holder, is a wing nut that allows the user to adjust the positioning of the activity screen longitudinally and rotationally along the extension rod.
Located in close proximity to the wing nut is an angle adjustment knob, which allows the user to rotate the connection member, thereby rotating the activity screen. The child then can play games and will have the activity screen directly in front of them and at an appropriate distance. The screen can also be locked in various tilted positions for optimum viewing and access for children of any size.
These games are all one piece, so there are no pieces to be dropped on the floorboard of the vehicle or possibly swallowed by younger siblings.
The present invention allows parents to concentrate on the task of driving the vehicle without the occurrence of an extraneous interruption. To change screens, the user removes the extension rod hook from the extension rod and slides off the current screen. The desired screen is then slid onto the extension rod and the user reattaches the rod hook to the extension rod and the extension rod to the garment hook located in the rear seating area of the vehicle.
