Abstract

A viewing screen protective shield is set forth removably securable in association with a viewing screen, such as LCR screens, as found in fish finders and the like, which are typically exposed to adverse weather conditions. The protective shield is readily removable and replaceable and include convex peripheral edges to conform the shield to the convex screen with an outwardly extending tab formed outwardly of a single corner of the shield to enhance manual grasping thereof. To enhance securement of the shield to the associated screen, a plurality of transparent adhesive strips may be secured to an interior surface of the shield to enhance securement of the transparent shield to the associated screen.

Claims

1. to the viewing screen..]..Iadd.2. A method of using a thin film to protectively shield an electronic instrument comprising the steps of:

providing an electronic instrument having a face plate having an outermost major surface portion,

providing a thin, flexible, transparent, plastic film of generally constant thickness having a major surface portion, and

completely applying and releasably adhering the major surface portion of the film to the outermost major surface portion of the face plate.

2. Iaddend..Iadd.3. The method of claim 2 further comprising the step of:

applying a releasable, clear, transparent, adhesive layer between the film and the face plate for enabling enhanced securement of the film to the face plate. .Iaddend..Iadd.4. The method of claim 2 wherein the thin film providing step further comprises the step of;

providing the thin film as a single sheet of polarized film to minimize glare when utilized in an environment exposed to sunlight.

3. Iaddend..Iadd. . A method of using a thin film to protectively shield an electronic instrument comprising the steps of:

providing an electronic instrument having a polymeric face plate having an outermost major surface portion,

providing a thin, flexible, transparent film of polymeric material of generally constant thickness having a major surface portion, and

completely contacting the major surface portion of the film directly to the outermost major surface of the face plate without an intermediate adhesive layer therebetween while naturally releasably adhering the film to the

4. face plate. .Iaddend..Iadd.6. A protective shield and electronic instrument assembly comprising:

an electronic instrument having a face plate having an outermost major surface portion,

a thin, flexible, transparent, plastic film of generally constant thickness having a major surface portion completely applied to and releasably adhered to the outermost major surface portion of the face plate.

6. to sunlight. .Iaddend..Iadd.9. A protective shield and electronic instrument assembly comprising:

an electronic instrument having a polymeric face plate having an outermost major surface portion,

a thin, flexible, transparent film of polymeric material of generally constant thickness having a major surface portion completely in direct contact with and releasably adhered to the outermost major surface portion of the face plate without an intermediate adhesive layer therebetween. .Iaddend.

5. Iaddend..Iadd.7. The assembly of claim 6 further comprising:

a releasable, clear, transparent, adhesive layer between the film and the face plate for enabling enhanced securement of the film to the face plate. .Iaddend..Iadd.8. The assembly of claim 6 wherein the film is a single polarized sheet to minimize glare when utilized in an environment exposed
