Telescoping slide rail with latching and alignment mechanisms

A telescoping slide rail assembly comprising:

• a stationary slide rail and an intermediate slide rail interconnected such that the intermediate slide rail is movable relative to the stationary slide rail to extend and retract between a fully extended position and a fully retracted position;
• a mounting slide rail interconnected to the intermediate slide rail for movement relative thereto such that the mounting slide rail extends and retracts relative to the intermediate slide rail between a fully extend position and a fully retracted position;
• the intermediate slide rail including a latch mechanism that engages a first opening in the stationary slide rail when the intermediate slide rail is disposed in the fully extended position in order to secure the intermediate slide rail in the fully extended position until the latch mechanism is disengaged;
• and
• the latch mechanism including an second opening formed in the intermediate slide rail, an arm having a bearing portion defined on an inner end of the latch arm and an interlock defined on an outer end of the latch arm and a biasing element configured to bias the bearing portion in the direction of an outer end of the intermediate slide rail and disposed such that the interlock engages the first and second openings, when aligned, and prevents unwanted movement of the intermediate slide rail toward the fully retracted position, wherein a tongue defined at an inner end of the mounting slide rail is configured offset from a wall of the mounting slide rail and the tongue is passed over the interlock in order to engage the bearing portion and disengages the latch mechanism by moving the bearing portion in a direction opposite the direction of the outer end of the intermediate slide rail when the mounting slide rail is moved toward the fully retracted position such that the intermediate slide rail will subsequently be moved toward the fully retracted position.
