Patent ID: 7878607

Claim:
A ball bearing slide assembly comprising: a first slide, the first slide forming a release portion; a second slide slidably receiving the first slide; a slide-aiding member slidably received between the first and second slides, and comprising a plurality of ball bearings slidably sandwiched between the first and second slides for facilitating the sliding movement of the first slide relative to the second slide, a locking portion extending from an end of the slide-aiding member and defining a locking hole; and a positioning member mounted to the second slide and forming a resilient cantilever, a positioning block being formed on the resilient cantilever and engaging in the locking hole of the slide-aiding member for temporarily locking the slide-aiding member to the second slide such that the first slide is slidable inward along the slide-aiding member without pushing the slide-aiding member inward, the cantilever forming a protrusion, when the first slide is further slid inward, the release portion of the first slide urging the protrusion of the cantilever to deform the cantilever of the positioning member to disengage the positioning block of the cantilever from the locking hole of the slide-aiding member such that the slide-aiding member is slidable relative to the first and second slides; wherein the locking portion is adjacent to the positioning member, a pressing tab extends from the positioning member, adjacent to the positioning block of the cantilever, and a distal end of the locking portion is inserted in a gap between the pressing tab and the positioning block of the cantilever and pressed by the pressing tab.
