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 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.

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.

Display for personal computer

The liquid crystal display of a portable computer is pivotally mounted with respect to a base fixed to the computer chassis. The pivot mount is effected by means of a pivot shaft arrangement that operates, in addition, to secure the opposite end portions of a circuit strip extending between and electrically connecting the terminals on the display and the base, respectively. The pivot shaft is axially split to secure an intermediate portion of the circuit strip whereby that portion of the circuit strip that extends from the base is windingly received on the exterior of the shaft to accommodate pivotal movement of the display. The other end of the strip is secured within the split segments of the shaft and extends axially therefrom within the display housing.

Contact strip-to-flex bushing connector

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.

Locking mechanism and support legs for removable display assembly

Personal computer

A portable computer includes a plate mounted to the chassis for pivotal movement between a position covering the connector terminals in the chassis rear wall to a position angularly spaced therefrom wherein the plate extends below the lower surface of the chassis thereby supporting the rear of the chassis in raised relation with respect to the front thereof. Cam surfaces consisting of angularly spaced flats are engageable with cooperating spring-biased followers for retaining the plate in its various angularly spaced positions.

Three-position closure panel

A peripheral or stand-alone computerized stamp printer is provided particularly for office use in which a print assembly including a pressure cam and leaf spring arrangement is associated with a heated print head which contacts and impresses a daisy wheel character against an imprinting tape in a confined cartridge to serially print computer-selected letters or characters on a binder, binder spine, or other workpiece. The printer assembly may move on an X or Y axis along a fixed or movable gantry upper arm. If the gantry is fixed, means are provided for moving paper stock, binders or other workpieces into proper position for clamping on a work surface on the top surfaces of the printer chassis. A spine-holding drawer may be provided in the chassis for supporting the spine of a binder for printing letters, logos, or the like, on the binder spine. The print assembly is a discrete unit and includes a replaceable tape cartridge fitted into drive mechanisms within the printer assembly.

A two-part binding system includes one or more bifurcated posts integrally extending from a clamping strip or member. The posts are inserted into one or more apertures in a stack of punched paper or other material and a second clamping strip having one or more integral or separate latching buttons inserted over and around the posts. Each button includes one or a pair of toothed pawls integrally hinged to a cross bar extending across a button aperture. The posts contain a series of transverse ratchets facing each other. As the second strip and its integral or snap-in latching button is manually pressed over the posts toward the first clamping strip, the teeth of the pawl teeth ratchet successively into the posts toward the base of the posts until the stack of paper is firmly grasped and the teeth mesh with a final transverse ratchet. At this position, the strips are bowed putting the edges of the stacked sheets in compression. A spine is also disclosed which has a series of parallel spaces score lines, and is bent around the edges of both clamping strips and firmly adhered to the strips. A simple tool to unlock the pawls is also disclosed. This allows substitute pages to be inserted into the stack and the same clamping strips to be manually reconnected.
