Claim Text:
1. A slide rail assembly comprising: a first rail; a second rail slidably connected to the first rail, the second rail having an opening; a third rail slidably connected to the second rail; a guiding base provided on the first rail to protrude therefrom toward the second rail, the guiding base having a pair of guiding portions and a stop portion defining a guiding path, the guiding path being closed at one longitudinal end by the stop portion and extending longitudinally to a guiding entrance in communication therewith; a first contact member provided on the second rail, the first contact member being deflectable and having a pair of first contact portions extending between the second and third rails, and a pair of second contact portions connected to the first contact portions and passing through the opening of the second rail to extend between the second and first rails; and a second contact member provided on the third rail, the second contact member having at least one lateral portion extending between the second and third rails for engagement with one of the first contact portions of the first contact member; wherein the guiding path of the guiding base defines a first width, the guiding entrance of the guiding base defines a second width, and the second contact portions of the first contact member define a third width therebetween, the third width being greater than the first width but less than the second width; wherein when the third rail is longitudinally displaced from a retracted position relative to the second rail, the lateral portion of the second contact member engages a corresponding one of the first contact portions of the first contact member for displacement therewith; and wherein as the second and third rails displace together beyond a predetermined position relative to the first rail, the second contact portions of the first contact member are received in conformed manner through the guiding entrance into the guiding path of the guiding base to be longitudinally stopped therein, the first contact member being responsively deflected to displace the first contact portions toward each other and disengage from the lateral portion of the second contact member, the second contact member being thereby released to pass over the first contact member for displacement of the third rail relative to the second rail.
