A portable computer having a base housing and a removable display pivotably mounted thereon, the display being removable from the base housing to be made free-standing on pivotable support feet, while having a removable electrical cable to the base housing.

Personal computer docking station

A docking module facilitates conversion of a portable computer between a lap-top mode of operation and a desk-top mode of operation by permitting simultaneous attachment of the computer to a plurality of electrical connectors thereby eliminating the need for individual cable connections between the computer and the respective individual apparatus. Toggle latches that attach the docking module to the computer chassis contain spring biased latches designed to emit an audible signal indicating proper alignment between the complementary connectors on the facing surfaces of the docking module and the computer chassis, whereby toggling of the latches can be undertaken without danger of damaging the connectors.

Docking module

A liquid crystal display for a portable computer is adapted for pivotal mounting to a base. The pivot hinge apparatus includes a torsion rod that is operative to counterbalance the display against the effect of gravity in various angular positions with respect to the base. A band brake cooperates with the torsion rod to permit angular adjustment of the display with respect to the computer.

Torsion bar and band brake

A battery pack apparatus particularly adapted for use on a portable appliance, as for example, a lap-top computer, is removably attached to the appliance by a coupling arangement that is organized so as to compel a wiping action to occur between the contacts of the apparatus and those of the appliance during assembly and disassembly of the apparatus to the appliance. In this way, the buildup of oxide deposits on the respective contacts is prevented. Also disclosed is a detent operated latching arrangement in which the detent is operated by a spring-biased, cam-actuated lever arm that, in turn, is operated by a spring-biased selectively operated actuator bearing a cam which cooperates with an inclined plane follower surface on the lever arm.

Locking arrangement for a battery pack

Display for personal computer

A liquid crystal display for a portable computer adapted for utilization as an integral part of the computer chassis is separable therefrom to be free-standing in a position remote from the chassis thereby enhancing desk-top operation of the computer. The display possesses locking members that serve to secure the display to the chassis. Manually operated levers effect movement of the locking members between a display-locking condition and a display-releasing condition. Following release of the display the locking members and the levers serve as supports enabling the display to be free-standing remote from the chassis.
