Abstract

A mobile information handling system comprising a chassis having a processor, a memory, and a wireless interface with a display screen operatively coupled to the chassis and the chassis having a spring, such as shape memory foam pads, internally mounted thereon and compressed between the chassis and the display screen and a mechanical connector fittingly engaging an access side of the chassis with the display screen, wherein the mechanical connector maintains pressure on the spring by holding the display screen in a closed position and an access seam at the edge of the display screen is operable to open due to a counter force exerted by the spring when the mechanical connector is disengaged from the display screen.

Claims

1. A mobile information handling system comprising:

a chassis having a processor and a memory;

a display screen operatively coupled to the chassis;

the chassis having a compressive force foam pad internally mounted thereon and compressed between the chassis and the display screen;

an attachment screw inserted through an access side of the chassis and fittingly attached to a screw receiving nub operatively coupled to the display screen, wherein the attachment screw maintains pressure from the display screen on the compression force foam pad; and

an access seam at the edge of the display screen operable to open due to a counter force exerted by the compression force foam pad when the attachment screw is removed from the screw receiving nub.

2. The system of claim 1, wherein the display screen includes a glass surface, display electronics and a display screen bezel operatively coupled between the compressive force foam pad and the display screen glass surface.

3. The system of claim 1, wherein a plurality of attachment screws are inserted through the access side of the chassis and fittingly attached to a plurality of screw receiving nubs operatively coupled to the display screen.

4. The system of claim 1, wherein the compressive force foam pad is mounted on the chassis along the access side of the chassis.

5. The system of claim 1, wherein the compressive force foam pad engages the display screen in a closed position outside an active area of the display screen.

6. The system of claim 1, further comprising:

a hinge mounted on a second side of the chassis and opposite to the access side to provide hinged access in an open position.

7. The system of claim 1, further comprising:

an interlock internally mounted along a second side of the chassis;

a corresponding guide mounted on the display screen for aligning the display screen with respect to the chassis.

8. The system of claim 7, wherein the interlock internally mounted along a second side of the chassis aligns the display screen via snap fit engagement of the corresponding guide into the interlock and wherein the interlock is disengageable from the corresponding guide with application of force.

9. A mobile information handling system comprising:

a chassis having a processor, a memory, and a wireless interface;

a display screen operatively coupled to the chassis;

the chassis having a spring internally mounted thereon and compressed between the chassis and the display screen;

an attachment screw inserted through an access side of the chassis and fittingly attached to a screw receiving nub operatively coupled to the display screen, wherein the attachment screw maintains pressure from the display screen on the spring; and

an access seam at the edge of the display screen operable to open due to a counter force exerted by the spring when the attachment screw is removed from the screw receiving nub.

10. The system of claim 9, wherein the spring is selected from a compression spring, a leaf spring, or a shape memory urethane foam pad.

11. The system of claim 9, wherein a plurality of attachment screws are inserted through the access side of the chassis and fittingly attached to a plurality of screw receiving nubs operatively coupled to the display screen.

12. The system of claim 9, wherein the spring is mounted on the chassis along the access side of the chassis.

13. The system of claim 9, wherein the spring is mounted on the display screen corresponding to the access side of the chassis.

14. The system of claim 9, wherein the spring engages the display screen in a closed position outside an active area of the display screen.

15. The system of claim 9, further comprising:

the display screen hinged to the chassis along a second side of the chassis.

16. The system of claim 9, further comprising:

a chassis bezel mounted between the chassis and edge of the display screen wherein the access seam is disposed between the chassis bezel and the edge of the display screen.

17. A mobile information handling system comprising:

a chassis having a processor, a memory, and a wireless interface;

a display screen operatively coupled to the chassis;

the chassis having a spring internally mounted thereon and compressed between the chassis and the display screen;

a mechanical connector fittingly engaging an access side of the chassis with the display screen, wherein the mechanical connector maintains pressure on the spring by holding the display screen in a closed position; and

an access seam at the edge of the display screen operable to open due to a counter force exerted by the spring when the mechanical connector is disengaged from the display screen.

18. The system of claim 17, wherein the spring is selected from a compression spring, a leaf spring, or a shape memory urethane foam pad.

19. The system of claim 17, wherein mechanical connector is selected from a mechanical latch, a pin, or an attachment screw for engaging the access side of the chassis with the display screen.

20. The system of claim 17, further comprising:

the display screen hinged to the chassis along a second side of the chassis.
