Abstract: The present invention relates to a pivotal armrest apparatus which comprises a cradle having a direct pivotal mechanism mounted on an anti-slip member. The pivotal mechanism automatically converts with the anti-slip member from the irregular movements of fingers (i.e. typing a keyboard) into stress releasing movements over the forearm without impairing a specific part of the wrist, whereby RSI can hardly be generated on the upper torso, nerves, and muscles. Also, the armrest enables a proper degree of rigidity to allow no drifting of the fingers, improves the repeatability of the finger position, and makes the installation area minimum while it is detachable and used as a comfortable rest means for respite.

A multi-height connecting and actuating structure enables the auxiliary pad to be positioned relative to the main keyboard tray at one of a plurality of heights by manual actuation of a single lever which is swingable through only a small angular extent.

Abstract: An adjustable support apparatus for supporting an object, such as a keyboard. The apparatus has a rotatable arm to which a rotatable support plate is attached. Rotation of the arm allows the height of the support plate to be adjusted. Rotation of the support plate allows its inclination to be adjusted. A constant force spring applies a varying upward moment to the support arm that approximates the varying downward weight moment applied to support arm, thereby restraining downward motion of the arm and making it easier for the user to raise the arm. Ratchet and pawl mechanisms lock the angular orientation of the support arm and the inclination of the support plate. The support plate is pivoted to the support arm so that twisting of the support plate disengages both the height and the inclination locking mechanisms.

According to a preferred embodiment, the vertically movable member comprises a cable, the counterbalancing return-force producing assembly comprises a first, spring-loaded reel, and the movement-resisting assembly comprises a second reel on which turns of the cable are wound and provided with at least one lateral face, and at least one friction disk applied to the lateral face of the second reel to resist to vertical movement of the wire.

Abstract: An armrest construction for chairs includes an armrest support having a lower end constructed for attachment to a chair, an upper end, and a mounting block attached to the upper end. A pivot block is pivoted to the mounting block at a main pivot, the pivot block having an upwardly-extending follower. First and second gears are each pivoted to the pivot block, the gears having intermeshing teeth at an inner end such that rotation of the first gear causes the second gear to simultaneously rotate in an opposite direction, the first and second gears further having outer ends. A support plate having pivot/slide members engages the outer ends of the first and second gears, and further has a guide operably engaging the follower to guide lateral movement of the support plate along a predetermined path.
