Abstract: A sliding mechanism includes a slide frame and a resilient plate fixed on the slide frame, has a front section exposed from a front end of the slide frame. A first fixing element mounted on the slide frame, has a protrusion extending outwardly from the front end along a longitudinal direction, wherein the protrusion is constituted by two concentrically disposed cylindrical portions with different diameters. A casing includes a second fixing element having at least one engaging hole with a cross-section adapted to engage the outer periphery of one of the cylindrical portions of the protrusion while the hook unit of the resilient plate engages an end plate of the slide frame, thereby preventing untimely disengagement of an assembly of the slide frame, the resilient plate and the first fixing element from the casing.

Abstract: A sliding mechanism with locking function includes a slide frame and a resilient plate. The slide frame includes opposite front and rear ends and an end plate formed at the front end and extending outward from the front end in a transverse direction relative to a longitudinal length of the slide frame. The end plate is formed with a through hole. The resilient plate has a width smaller than that of the slide frame, a rear section fixed to the slide frame and a front section opposite to the rear section and formed with a locking element exposed to an exterior of the through hole in the end plate in such a manner that the locking element is movable limitedly and resiliently in the transverse direction upon an external force applied thereto.

Abstract: A positioning device for a sliding mechanism includes slidably connected exterior plate, intermediate plate and interior plate, characterized by the exterior plate having a stop block; the intermediate plate formed with a through hole, including having a pivot element mounted pivotally adjacent to the through hole and having a projection extending through the hole to engage the stop block, thereby preventing sliding action between the exterior and intermediate plates, a resilient element having a free end in contact with the rear end of the pivot element; and the interior plate having a push element with cam face; when an external force applied on so as to cause sliding action between the interior plate and the intermediate plate results in abutment of the cam face against the resilient element, thereby deforming the resilient element and rotating the pivot element about its axis, thereby disengaging the projection from the stop block.

Abstract: A positioning device for a sliding mechanism that includes exterior, intermediate and interior plates, each plate defining inner and outer side surfaces, the positioning device is characterized by: the intermediate plate having a stop block formed on the inner side surface; and the interior plate including an elongated release rod that is mounted movably on the outer side surface and that has a limit notch receiving the block, and a resilient element engaging the propeller portion for restricting a longitudinal movement of the rod, the interior plate having a position limiting unit constituted by two limiting stubs mounted movably on the outer side surface and having pointed free ends and a biasing element for biasing the limiting stubs in such a manner that the pointed free ends extend into the notch to contact opposite ends of the block, thereby preventing relative movement between the interior and intermediate plates.
