Patent ID: 8550416

Claim:
A mounting apparatus for mounting a slide rail to a rack post, the rack post defining a through hole, the mounting apparatus comprising: a supporting bracket fixed to the slide rail, the supporting bracket comprising an end plate and an inserting pin extending from the end plate to extend through the through hole of the rack post; a latch member comprising a slide bracket slidably coupled to the supporting bracket, and a positioning pin secured to the slide bracket, the slide bracket comprising a blocking plate parallel and aligned with the end plate of the supporting bracket, the positioning pin comprising a plurality of abutting blocks stacked up one by one and having different distances relative to the blocking plate; and a holding member comprising a mounting portion fixed to the supporting bracket, an elongated portion extending from a front end of the mounting portion, and a retaining portion extending from a front end of the elongated portion, the retaining portion forming a rearward side facing the mounting portion; wherein the latch member is operable to slide between a locking position where the blocking plate of the latch member abuts against a side of the rack post opposite to the end plate of the supporting bracket to prevent the inserting pin from disengaging from the through hole of the rack post, and an unlocking position where the blocking plate of the latch member moves away from the rack post to enable the inserting pin to disengage from the through hole of the rack post; the retaining portion of the holding member selectively abuts against one of the abutting blocks of the positioning pin to keep the latch member at the locking position, and the retaining portion selectively abuts against one of the abutting blocks of the positioning pin to keep different distances between the blocking plate of the slide bracket and the end plate of the supporting bracket to sandwich rack posts of different thicknesses.
