    摘要： A multi-adjustable armrest assembly for a chair can be adjusted in a variety of different aspects including laterally, vertically, forwards and backwards, and rotationally. Such an armrest assembly can include an armrest base securable to a chair and having a tubular portion, an armrest support having a vertical leg and a horizontal leg slidably disposed in the tubular portion, a shroud slidably disposed on the vertical leg, a post member attached to the shroud, a collar connected to the post, and an armrest connected to the collar. Additionally, the armrest can have a bottom portion slidably connected to the collar and the collar can be rotatably connected to the post. Furthermore, a positive adjustment mechanism can be provided to control each adjustable aspect of such an armrest assembly.

    摘要： A chair tilt control mechanism for a pedestal base chair having a chair control housing mounted on the pedestal chair base and pivotally supporting a chair seat support member. A laterally movable front stop member retained within the chair control housing is movable and contacts the front flange of the chair seat support member and limits the pivotal movement of the chair seat support member to predetermined angular positions with respect to the chair control housing and the floor supporting the chair. Also disclosed is a lever member adapted to lock the chair seat support member in one or more predetermined angular positions. Also disclosed is a hollow plastic pivot pin for pivotally connecting a chair control housing to a chair seat support member.

    摘要： A tension control device is provided, for example, for locking and unlocking a movable support arm for a keyboard or the like, by engaging or disengaging rotational joints having axially displaceable rotationally lockable couplings traversed by a tension line. A control, preferably a caliper, has levers pivoted on a pin, normally biased by a spring to close. The spring pulls the caliper closed; however, the caliper is arranged by linkages to clamp tension onto the line rather than to couple spring tension to the line. A front linkage isolates the spring bias from the line when closed, by folding inwardly such that tension is transmitted substantially exclusively via compression of two pivoted members of the from linkage that align nearly parallel to the line. The biasing spring is coupled between a rear linkage that operates oppositely, and a fixed point such as the caliper pivot pin. The two linkages are such that the spring has maximum mechanical advantage to hold the caliper closed when in the closed position, tension nevertheless being rigid, clamped and not resilient, for rigidly locking the support arm.
