Abstract:
1. A slide rail assembly comprising: an outer rail comprising an elongated rail body forming a holding portion, and a support bar fixed to the rail body and extending along a lengthwise direction of the rail body, the holding portion being adjacent to a front end of the support bar; an intermediate rail slidably coupled to the outer rail; an inner rail slidably coupled to the intermediate rail, and forming a stop portion; and a latch member pivotably mounted to the intermediate rail, and comprising a first lock tongue extending towards the outer rail, and a second lock tongue extending towards the inner rail; wherein the support bar of the outer rail supports the first lock tongue of the latch member to keep the latch member to a locking position, when the second lock tongue of the latch member abuts against the stop portion of the inner rail to enable the intermediate rail to slide forward in synchronization with the inner rail; the latch member is pivoted to an unlocking position, when the first lock tongue of the latch member is engaged with the holding portion in response to the first lock tongue sliding forward away from the support bar, and the second lock tongue of the latch member disengages from the stop portion of the inner rail to enable the inner rail slide forward relative to the intermediate rail; and the intermediate rail comprises a tab protruding towards the inner rail, the latch member further comprises a resilient arm resisting against the tab of the intermediate rail to be deformed in response to the latch member being at the locking position, thereby biasing the latch member towards the unlocking position.
