Abstract: A dynamic posture chair is disclosed which is capable of use in a range of sit/stand positions. The chair includes a mobile base that is selectively movable by the user and the chair member that is mounted to the base with a tilt mechanism that enables the chair member to be selectively and infinitely tilted over a predetermined of tilt positions while resistively restraining the chair member in the selected tilt position. The chair member includes seat and back members that relatively subtend an angle in the range of about 120 degrees to 135 degrees. The chair member has a uniquely shaped fixed seat/back contour that instantly supports in comfort the back, buttocks and thighs of the user in its lowest and highest vertical positions, and in all positions in between.

Abstract: Multi-jointed and pivoted support system for support of a flat panel video display and/or keyboard tray, incorporating a plurality of pivot points providing for pivotal motion of one or more components about a plurality of vertical, horizontal and elevational axis. Support arms having elevational pivot assemblies, including plastic friction washers and nitrogen gas springs which offer elevational arm control requiring constant and predetermined positioning effort on the part of the video display operator and keyboard operator.

Abstract: A video monitor suspension system including a four bar linkage arm for adjustable and positionable vertical and horizontal support of a video monitor, computer, computer keyboard, or a like structure. A weight counterbalance sliding anchor mechanism assembly adjustably compensates for various weights of a load held by an angled arm. Gas springs provide for vertical support of a four bar linkage arm. Reinforcement channels in the four bar linkage arm members provide for increased torsional rigidity of the video monitor suspension system and allow for the incorporation of lighter weight linkage arm members. A large pivot bearing assembly also provides for stability when used with an input device, such as a keyboard. Additional structure provides for the safety of the computer suspension system operator.

Abstract: Vertical work center for positioning a computer monitor vertically and horizontally about a floor or ceiling mounted column. A positionable arm is pivotally secured to the upper portion of the mounting column in the case of a floor mounted column or to the lower portion of the mounting column in the case of a ceiling mounted column. The outward end of the positionable arm includes a tilt/swivel mount which supports a monitor caddy.

Abstract: A suspension system for a personal computer or monitor comprising a carriage in which the monitor or computer is mounted, the carriage being supported from above by a frictionally secured swivel and tilt mechanism in turn attached to a pivotable and rotatable support arm. The support arm is balanced by an adjustable pneumatic pressure cylinder, and is mounted on a roller assembly such that it may be carried along a path defined by a track assembly, thereby permitting the monitor or computer to be transported between first and second positions, as well as simultaneously being raised or lowered vertically, tilted, rotated, or swiveled. The track assembly may be attached to the underside of a shelving unit and incorporated into a modular partition system, or attached to a freestanding frame.

Abstract: A device designed for mounting cathode ray tube has the ability to both tilt and swivel in order to provide a most advantageous angle at a working station. A cross-piece is rotatably mounted in a base and a mounting plate is designed to tilt about the cross-piece, there being a frictional engagement between the cross-piece and a portion of the mounting plate. This frictional engagement has provision for varying the amount of friction so as to lock or allow varying difficulty of tilt depending on the weight of the device to be mounted and the desire of the operator. The device is designed for one-handed operation.
