Abstract

A stowable wrist support assembly for a portable computer of the type having a bottom housing with top and bottom surfaces connected by a vertical peripheral side surface and having a keyboard on the top surface extending to a front edge and a top housing pivotally mounted to a back edge of the bottom housing, the support assembly comprises a generally thin flat panel having generally planar top support surface, a rear edge formed with a lip for detachably engaging and latching behind a shoulder proximate the front edge of the lower housing, and a panel support member extending downward from beneath the panel for engaging a lower front edge of the lower housing for supporting the panel in an outward position substantially in the plane of the keyboard.

Claims

1. A stowable wrist support assembly for a portable computer of the type having an upper housing and a lower housing, said lower housing having a front edge and a back edge, said upper housing being pivotally connected to the back edge of the lower housing, the lower housing having top and bottom surfaces connected by a vertical peripheral side surface and having a keyboard disposed on the top surface, said support assembly comprising:

a generally thin flat panel having a generally planar top support surface and a rear edge formed with a lip for detachably engaging and latching at a location proximate to the front edge of the lower housing; and

a panel support member extending downwardly from the underside of said thin flat panel for engaging the front edge of said lower housing for supporting said thin flat panel in an outwardly extending position substantially in the plane of the keyboard.

2. A wrist support according to claim 1 wherein said support assembly is stowable between said upper and lower housings when said upper housing is closed onto said lower housing.

3. A wrist support according to claim 2 wherein said panel support member comprises a brace member hinged to an underside of said thin flat panel and including a finger at an outermost end adapted for engagement with said lower housing.

4. A wrist support according to claim 3 wherein the underside of said thin flat panel comprises a recess having a shape for accommodating said brace member so that said brace member is stowable within said recess.

5. A wrist support according to claim 1 wherein said thin flat panel further comprises a front edge opposite said rear edge, said front edge having a front edge lip for increasing the stiffness of said thin flat panel, and wherein the lower housing includes a shoulder formed proximate to said front edge, and the rear edge of said thin flat panel is adapted for hooking over said shoulder.

6. A wrist support according to claim 5 wherein said front edge lip and said rear edge lip are spaced to extend between rows of keys on said keyboard for stowage of said thin flat panel on top of said keyboard.

7. A wrist support according to claim 1 wherein said support member comprises a thin flexible sheet and said brace member is a continuation of said flexible sheet that slideably extends below said lower housing for stowage.

8. A wrist support according to claim 7 wherein said flexible sheet comprises a laminate of polycarbonate and sheet metal.

9. A wrist support according to claim 7 wherein said lower housing includes an upper and a lower portion and a slot disposed therebetween, and wherein said rear edge of said support member extends through said slot.

10. A wrist support according to claim 7 further comprising detent means for maintaining said flexible sheet in selected extended and retracted positions.

11. A wrist support according to claim 1 wherein said support assembly further comprises a first panel defining said thin flat panel and a second panel defining said brace member, and said brace member is hinged to an outermost edge of said first panel and including an outermost edge adapted for latching engagement with a lower front edge of said lower housing.

12. A wrist support according to claim 11 wherein said first panel and said second panel have an underside that includes a plurality of recesses that match keys on said keyboard, said plurality of recesses for receiving said keys to enable stowage of said wrist support on top of said keyboard when said upper housing is closed onto said lower housing.

13. A wrist support according to claim 11 wherein one of said first and second panels comprises a slot and link members pivotally mounted in said slot and the other of said first and second panels includes a pin for latching said link members to situate said first and second panels in an angled relationship for engagement and support on said front edge of said lower housing.

20. A wrist support according to claim 3 wherein the keyboard includes keys arranged in rows and columns, and said wrist support further comprises a hinge that connects said thin flat panel with said brace member, wherein said hinge is positioned on said thin flat panel so that said hinge is situated between the keys when said upper housing is closed onto said lower housing.

14. A stowable wrist support assembly for a portable computer of the type having a bottom housing including a front edge, a back edge, spaced top and bottom surfaces connected by vertical peripheral side walls, a keyboard disposed on and substantially covering the top surface to the front edge, a shoulder formed proximate to said front edge, said portable computer including a top housing comprising a screen and hingeably mounted to the back edge of the bottom housing, said support assembly comprising:

a generally planar top support surface defined by a thin flat panel having a rear edge formed with a rear edge lip for detachably engaging and latching behind said shoulder; and

a support member extending downwardly from said thin flat panel for engaging said lower housing proximate to said front edge, said support member for supporting said thin flat panel in an outwardly extending position substantially in the plane of the keyboard.

15. A wrist support according to claim 14 wherein:

said thin flat panel comprises a front edge lip wherein said front edge lip and said rear edge lip are spaced to extend between rows of keys on said keyboard for stowage of said panel on top of said keyboard; and

said support member comprises a brace member hinged to an underside of said thin flat panel and including a finger at an outermost end adapted for latching engagement with said lower housing, and said panel support member is stowable in a recess therein.

16. A wrist support according to claim 14 wherein said thin flat panel has an outer most edge and said support member is defined by a second panel having an outer edge and said second panel is hingeably connected on its outer edge to said outermost edge of said thin flat panel, said second panel including an inner edge adapted for engagement with said lower housing, wherein said first panel and said second panel have an underside that includes a plurality of recesses that match keys on said keyboard, said plurality of recesses for receiving said keys to enable stowage of said wrist support on top of said keyboard when said upper housing is closed onto said lower housing.

17. A wrist support according to claim 16 wherein one of said first and second panels further comprises a slot and link members pivotally mounted in said slot, and said other of said first and second panels comprises a pin latchably engagable with said link members for latching said first and second panels in an angled relationship for engagement and support on said front edge of said lower housing.

18. A wrist support according to claim 14 wherein said lower housing includes an upper and a lower portion and a slot disposed therebetween, and wherein said support panel comprises a thin flexible sheet, said rear edge of said support member extends through said slot and said support member is a continuation of said flexible sheet that slideably extends below said lower housing for stowage.
