Abstract: A modular table top system includes a variety of differently shaped modular table tops, including rectangular, triangular, curved, semi-circular, etc., which can be selectively linked to form customized table or desk shapes. Each modular table top accommodates leg brackets along linkable edges thereof in alternative positions. In a first position, each leg bracket is positioned completely under the table top proximate the linkable edges thereof, and, in a second position, each leg bracket is rotated 180 degrees to a position straddling two adjacent linked table tops. With leg brackets straddling adjacent table tops, the number of legs required to support a linked structure is reduced, allowing greater freedom of chair placement, and reducing overall cost.

Abstract: An adjusting mechanism is provided for selectively positioning a chair component such as an armrest or a backrest. The adjusting mechanism utilizes a first member having a longitudinal axis. A plurality of ratchet recesses are spaced longitudinally along the first member. A second member having a longitudinal axis is disposed in substantially parallel relation with the longitudinal axis of the first member. The second member supports a ratchet dog. The first and second members are relatively movable along their longitudinal axes between a ratchet dog-blocking position and a ratchet dog-releasing position. A spring is mounted on the second member for urging the ratchet dog into successive engagement with the plurality of ratchet recesses. A slider is movably mounted on the second member for selectively displacing the spring to effect disengagement of the ratchet dog from the successive ratchet recesses.
