Abstract

A computer enclosure having a first enclosure portion with an integral display window and side panels, a resilient elastomeric molding covering the side panels by encapsulating a flange portion around the side panels so as to form a permanent mechanical bond between the resilient molding and the side panels. An elastomeric fitting connects to the first enclosure portion surrounding the display window to protect the window from impact damage. An elastomeric gasket fits on the inside perimeter of the display window to form an impact-resistant interface between the display window and a computer display component within the hand-held computer. A second enclosure portion forms the bottom of the computer enclosure.

Claims

1. An enclosure for a hand-held computer comprising:

a first enclosure portion having a top panel, a display window formed integral with said top panel, and side panels connected to said top panel;

a second enclosure portion having a bottom panel and side panels connected to said bottom panel; and

a resilient molding attached to said first enclosure so as to at least partially surround said first enclosure side panels and top panel while leaving said display window substantially unobscured, said molding adapted to engage said second enclosure side panels so as to form a seal between said first and second enclosure portions.

2. The enclosure of claim 1 wherein said first enclosure side panels have a flange portion that is encapsulated by said resilient molding to fixedly attach said resilient molding to said first enclosure side panels.

3. The enclosure of claim 2 wherein said flange portion has apertures therein, said resilient molding extending through said apertures to form a permanent connection between said resilient molding and said first enclosure side panels.

4. The enclosure of claim 1 wherein said first enclosure portion is a rigid, one-piece, molded unit.

5. The enclosure of claim 4 wherein said first enclosure portion is manufactured of a translucent plastic.

6. The enclosure of claim 1 wherein said resilient molding is manufactured of a flexible, impact resistant, elastomeric overmold bonded to said first enclosure portion.

7. The enclosure of claim 1, further including an external resilient fitting extending around said display window to protect said display window from impact damage.

8. An enclosure for a computer comprising:

a first enclosure portion shaped to receive a circuit board component and computer display component, said enclosure having a top panel, a display window formed integral with said top panel, and side panels forming a component receiving area, said display window having an inside surface and an inside perimeter portion that communicates with said display component;

a resilient covering attached to said side panels and said top panel forming a protective covering around said first enclosure such that said display widow is substantially unobscured; and

a second enclosure portion having a bottom panel and side panels connected to said bottom panel, said second enclosure side panels adapted to engage said resilient covering so as to form a seal between said first and second enclosure portions.

9. The enclosure of claim 8 wherein said resilient covering comprises an impact resistant elastomeric material molded onto said first enclosure side panels, and a fitting secured to said first enclosure portion around said display window.

10. The enclosure of claim 8 wherein said first enclosure portion is manufactured of a rigid, one-piece, molded enclosure portion.

11. The enclosure of claim 10 wherein said first enclosure portion is manufactured of a translucent plastic enclosure portion.

12. The enclosure of claim 8 wherein said first enclosure side panels have a flange portion encapsulated by said molding to fixedly attach said resilient molding to said first enclosure side panels.

13. The enclosure of claim 12 wherein said flange portion has apertures therein, said resilient molding extending through said apertures to form a permanent connection between said resilient molding and said first enclosure side panels.

14. The enclosure of claim 8, further including a resilient gasket connected to said inside perimeter of said display window to form an impact resistant interface between said display window and the computer display components.

15. The enclosure of claim 14 wherein said component receiving area shaped to loosely receive the computer display component in a nesting manner thereby allowing said display component to move relative to said first enclosure.

16. The enclosure of claim 8 wherein said first enclosure portion and said second enclosure portion are sized to form a housing for a hand-held computer.

17. A method of manufacturing a computer enclosure having a top enclosure portion with a top panel, a display window integral with said top panel, and side panels connected to the top panel, and a bottom enclosure portion with a bottom panel and side panels connected to the bottom panel, comprising the steps of:

molding the top enclosure portion with the display window being transparent;

molding the bottom enclosure portion; and

injection-molding a resilient elastomeric material onto the top enclosure side panels such that the display window is substantially unobscured, and the resilient elastomeric material encapsulates at least a portion of the top enclosure side panels.

18. The method of claim 17, further comprising the step of assembling the top and bottom enclosure portions with the resilient elastomeric material engaging the bottom enclosure side panels to form a seal between the top and bottom enclosure side panels.
