Slide rail mechanism

A slide rail mechanism comprising:

• a supporting frame comprising a disengaging feature;
• and
• a slide rail assembly movable with respect to the supporting frame, the slide rail assembly comprising a first rail, a second rail and a third rail, the first rail being an outer rail, the second rail being a middle rail, and the third rail being an inner rail;
• wherein the second rail and the first rail displace synchronously during a displacement of the second rail with respect to the supporting frame away from a first predetermined position along a first predetermined direction;
• wherein the disengaging feature of the supporting frame is configured to terminate a displacement synchronization between the second rail and the first rail when the second rail and the first rail are synchronously displaced to a second predetermined position along the first predetermined direction;
• wherein the slide rail assembly further comprises a first auxiliary member and a second auxiliary member, the first auxiliary member is arranged on the first rail, the second auxiliary member is arranged on the second rail, and the second rail and the first rail displace synchronously by an abutment of the first auxiliary member and the second auxiliary member during the displacement of the second rail with respect to the supporting frame away from the first predetermined position along the first predetermined direction;
• wherein one of the first auxiliary member and the second auxiliary member is movable, and the one of the first auxiliary member and the second auxiliary member is configured to move to a first state for abutting against another one of the first auxiliary member and the second auxiliary member in response to a resilient deformation of a resilient member;
• wherein the disengaging feature of the supporting frame is configured to allow the resilient member to be released to drive the one of the first auxiliary member and the second auxiliary member from the first state to a second state to disengage from the another one of the first auxiliary member and the second auxiliary member for terminating the displacement synchronization between the second rail and the first rail when the second rail is displaced to the second predetermined position.
