Patent ID: 7794029

Claim:
A ball bearing slide assembly, comprising: a first slide; a second slide slidably receiving the first slide and defining a receiving hole; a slide-aiding member comprising a plurality of ball bearings slidably sandwiched between the first slide and the second slide for facilitating the sliding movement of the first slide relative to the second slide, the slide-aiding member defining a slot; and a positioning member pivotably mounted to the slide-aiding member and forming a positioning tab, the positioning tab extending through the slot of the slide-aiding member configured to engage in the receiving hole of the second slide for locking the slide-aiding member with the second slide such that the first slide is slidable inward relative to the second slide without pushing the slide-aiding member inward, the first slide, when slid inward, capable of pushing the positioning member to pivot to disengage the positioning tab of the slide-aiding member from the receiving hole of the second slide such that the slide-aiding member is slidable relative to the first and second slides when the first slide slides relative to the second slide; wherein the second slide comprises a web and two arms respectively extending from two lateral edges of the web, the web forms a longitudinal base plate and two recessed troughs, an upper portion of the receiving hole is defined in the base plate and a lower portion of the receiving hole is defined in a junction of the base plate and a lower one of the troughs such that the positioning tab is capable of sliding into the lower portion of the receiving hole via the lower one of the troughs to engage in the upper portion of the receiving hole.
