Cam locking type sliding and swiveling device

Abstract

A sliding and swiveling device that includes a sliding plate having a surface for supporting an attachment unit such as a chair and two laterally spaced sliding portions. The device further includes a holder which has a pair of laterally spaced sliding sections that are in a sliding relationship with respect to the two sliding portions of the sliding plate. The holder also includes a sleeve portion which is dimensioned for receiving a sleeve member in a swivel relationship. The device also features a first locking assembly for releasably locking the sliding plate and holder against rotation with respect to the sleeve member. A second locking assembly is provided for releasably locking the sliding plate and holder against longitudinal sliding. The device features a handle member and an assembly for triggering a release of the first locking assembly upon adjustment of the handle member in a first direction (e.g., clockwise) and for triggering a release of the second locking assembly upon adjustment of the same handle member in a second direction (e.g., counter-clockwise). Biasing devices are provided to place the two locking assemblies in a locking state when the handle member is not rotated in one direction or the other. The invention also includes a method for manufacturing a sliding and swiveling device.
