Abstract

A portable computer docking station that is capable of allowing rotational movement of the computer'"'"'s viewable screen in at least three different planes, thereby facilitating viewing and other utilization (e.g., using a pen) of the screen within a motor vehicle. The docking station defined herein is provided with a means for heating the portable computer when the computer is positioned in the docking station'"'"'s holder portion. The heated holder portion effectively solves the problem of maintaining a portable computer at an operable temperature in cold environments. A vehicular computer assembly is also provided.

Claims

1. A docking station for a portable computer having a viewable screen, said docking station comprising:

a base portion; and

a holder portion positioned on said base portion and adapted for holding said portable computer therein, said holder portion being rotationally adjustable in at least three different planes and including a first bracket assembly rotationally adjustable on said base portion in one of said three different planes and a second bracket assembly rotationally adjustable in a second of said three different planes substantially perpendicular to said one of said planes in which said first bracket assembly is rotationally adjustable.

2. The docking station of claim 1 further including a third bracket assembly fixedly secured to said first bracket assembly, said second bracket assembly being rotationally adjustable on said third bracket assembly.

3. The docking station of claim 1 wherein a third of said three different planes is oriented at an acute angle with respect to said one of said three different planes in which said first bracket assembly is rotationally adjustable.

4. The docking station of claim 1 wherein said base portion comprises a support column, said first bracket assembly being rotationally adjustable on said support column in said one of said three different planes.

5. The docking station of claim 4 wherein said support column includes an outer part, and an inner part movably positioned within said outer part.

6. The docking station of claim 5 wherein said inner part is movable in a substantially linear manner within said outer part.

7. The docking station of claim 4 wherein said first bracket assembly includes a rotational sleeve, said rotational sleeve being rotationally movable on said support column.

8. The docking station of claim 1 wherein said holder portion further includes a support member, said support member rotationally adjustable with respect to said second bracket assembly.

9. The docking station of claim 1 further including means for heating said portable computer when said portable computer is positioned in said holder.

10. The docking station of claim 11 wherein said means for heating said portable computer includes a resistance heating element mounted on said holder portion.

11. The docking station of claim 1 wherein said holder portion further comprises a keyboard support member adapted for supporting a keyboard unit associated with said portable computer, and a screen support member adapted to support said viewable screen of said portable computer, said screen support member being pivotally connected to said keyboard support member.

12. The docking station of claim 11 wherein said means for heating said portable computer includes a first heating element mounted on said keyboard support member and a second heating element mounted on said screen support member.

13. The docking station of claim 12 wherein said first and second heating elements have a thin pad construction with heating elements disposed therein.

14. The docking station of claim 10 wherein said means for heating said portable computer is electrically coupled to an external power source other than the power source of said motor vehicle.

15. A vehicular computer assembly comprising:

a portable computer including a viewable screen;

a base portion adapted for being positioned within a motor vehicle; and

a holder portion positioned on said base portion and including means for holding said portable computer therein such that said viewable screen of said portable computer can be rotationally adjusted in at least three different planes, said holder portion further including a first bracket assembly rotationally adjustable on said base portion in one of said three different planes and a second bracket assembly rotationally adjustable in a second of said three different planes substantially perpendicular to said one of said planes in which said first bracket assembly is rotationally adjustable.

16. The vehicular computer assembly of claim 15 wherein said viewable screen of said portable computer is retained by said holder portion during said rotational adjustment of said viewable screen.

17. The vehicular computer assembly of claim 15 wherein said portable computer further includes a keyboard portion, said keyboard portion being retained by said holder portion during said rotational adjustment of said viewable screen.

18. The vehicular computer assembly of claim 15 further including a port replicator positioned on said holder portion and electrically coupled to said portable computer.

19. The vehicular computer assembly of claim 15 wherein said portable computer is pen-actuated.

20. The vehicular computer assembly of claim 15 further including means for heating said portable computer when said computer is positioned within said holder portion.

21. The vehicular computer assembly of claim 20 wherein said means for heating said portable computer comprises a resistance heating element mounted on said holder portion.

22. The vehicular computer assembly of claim 15 wherein said means for heating said portable computer is electrically coupled to an external power source other than the power source of said motor vehicle.
