Abstract
A soft case which encloses a portable device such as a hand held computer has a top cover portion which overlies a large screen at the front or top of the computer. This cover portion has a flat, soft foam pad which engages against the glass screen to cushion the screen and spread the force of any impact against the closed case at the screen. Further, there may be included in the screen cover a rigid member captured within the injection molded foam and spanning across the screen, providing further protection against impact to the screen.

A case for covering a hand held computer having a large frontal screen and a rigid frame around the screen,
- and for protecting the screen against impact, comprising,
- a base portion of the case and a cover portion of the case secured to the base portion,
- the cover portion being formed of a compressible material and extending over the computer screen and including screen padding means for engaging substantially the entire screen to cushion and distribute any impact or pressure occurring to the cover portion at the screen, and
- the screen cover portion further including a rigid member encapsulated within the cover portion and of a larger dimension than the screen so as to span across the screen and overlap the rigid frame, for further preventing impact or pressure from being transferred to the screen by transferring pressure to the rigid frame
A soft foam case for covering a portable device having a large frontal screen, and for protecting the screen against impact, comprising,
- a base portion of the case and a cover portion of the case secured to the base portion,
- the cover portion extending over the screen and including screen padding means for engaging substantially the entire screen to cushion and distribute any impact or pressure occurring to the cover portion at the screen,
- the case being formed of an injection molded neoprene polyethylene and polypropylene alloy which is foamed into a closed-cell soft foam during molding,
- the portable device having a rigid frame surrounding the screen, and the screen cover portion further including a rigid member encapsulated within the cover portion and a larger dimension than the screen so as to span across the screen and overlap the rigid frame, for further preventing impact or pressure from being transferred to the screen by transferring pressure to the rigid frame.
In combination with a hand held computer having a large frontal screen and a rigid frame around the screen, a case for covering and protecting the computer and for protecting the screen against impact, comprising,
- a base portion of the case and a cover portion of the case secured to the base portion,
- the cover portion being formed of a compressible material and extending over the computer screen and including screen padding means for engaging substantially the entire screen to cushion and distribute any impact or pressure occurring to the cover portion at the screen,
- the computer having a terraced configuration with a lower shoulder or ledge below the rigid frame and extending outwardly beyond the frame at least on two opposed sides of the computer, with a channel formed between the upper and lower ledges, and
- the base portion of the case having a pair of side walls positioned to engage against said two opposed sides of the computer and the side walls each including inwardly extending rails oriented longitudinally along the side walls, positioned to engage over the upper surface of the lower shoulder or ledge.
A computer case for covering a hand held computer having a screen and a rigid frame around the screen and for protecting the screen against impact, the screen surface being recessed below the frame surface, the case comprising:
- a base and a cover secured to the base, the cover being formed of a compressible material and having a portion extending over the computer screen and a portion extending over the frame, the portion of the cover over the screen extending below the portion of the cover over the frame in substantially the same amount that the screen is recessed below the frame.
