Abstract

A portable computer holder is adjustably mounted on a base portion that is attachable to the floor of a vehicle and is provided with a means for heating the portable computer when the computer is positioned in the holder. The heated holder effectively solves the problem of maintaining a portable computer at an operable temperature in cold environments.

Claims

1. A docking station for a portable computer having a viewable screen unit operably interconnected with a keyboard unit, said docking station comprising:

a base portion;

a holder coupled to said base portion and adapted for holding said portable computer, said holder comprising a keyboard support portion adapted to support the keyboard unit of said portable computer, and a screen support portion adapted to support said viewable screen unit of the portable computer, said screen support portion being pivotably connected to said keyboard support portion,

a means for heating said portable computer when said portable computer is positioned in said holder, said means for heating the portable computer including a first heating element mounted on said keyboard support portion and a second heating element mounted on said screen support portion.

2. A docking station, as set forth in claim 1, wherein said means for heating the portable computer includes a resistance heating element mounted on said holder.
