ABSTRACT:
BACKGROUND OF INVENTION
1. Field of Invention
This invention relates to projection type television screens and more particularly to an improved screen guard clip and method of mounting such protective guard on the various types of televisions.
Protective screen guards for projection-type televisions or so-called Big Screen TV's are well known to those skilled in the art. Such a screen guard is fabricated from a sheet of transparent plastic and dimensioned to closely fit within a peripheral frame of the television screen.
The screen guard is typically installed by means of a screen guard clip which engages both the edges of the screen guard and the edges of the screen frame to secure it in position.
A problem arises during the installation of after-market screen guards in that a screen guard clip for a Sony television, for example, will not properly fit onto a Mitsubishi or Zenith screen frame, etc.

BRIEF DESCRIPTION OF INVENTION
After much research and study into the above mentioned problems, the present invention has been developed to provide a versatile, cost-effective method of installing after-market screen guards on projection type television screens. The present invention provides a universal fit with big screen televisions of various manufacturers to give the consumer an after-market screen guard at a reasonable price.
The above is accomplished through the provision of an arcuate clip that is rolled into an elliptical shape at one end and includes an outwardly projecting locking tab when viewed in lateral cross-section. This elongated clip is made from a material with a memory which gives a spring action when deformed to hold the screen guard in place juxtaposed to the television projection screen.
There are four clips used in the normal installation, a bottom clip, a top clip, and two side clips to cover the entire periphery of the screen guard where such periphery joins the frame for the television screen.
In view of the above it is an object of the present invention to provide a universal screen guard clip that mounts the screen guard juxtaposed to the screen.
Another objection of the present invention is to provide a universal screen guard clip that inserts between the television screen and the television frame to support a protective screen guard over said screen.
Another object of the present invention is to provide a screen guard clip that is arcuate in cross section, is extruded, and is made of a material that has a memory.
Another object of the present invention is to provide a screen guard clip that is arcuate in cross section and includes an outwardly projecting locking tab that runs the entire longitudinal length of the clip.
Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawings which are merely illustrative of such invention.
