Buffering Device for the Slide Rail of a Drawer

A slide rail assembly, comprising:

• a fixed slide rail having a length between a first end and a second end, wherein said fixed slide rail has a rear wall and side walls that define an open channel that extends said length;
• a hook plate mounted to said rear wall of said fixed slide rail within said open channel, wherein said hook plate has a locking groove formed therein;
• a base affixed to said fixed slide rail within said open channel at said first end;
• a buffer frame disposed in said open channel between said base and said second end, wherein said buffer frame can move in said open channel between a first position in abutment with said base and a second position over said hook plate;
• a toggle plate mounted at a pivot connection to said buffer frame, wherein said toggle plate can rotate about said pivot connection between a free position and a locked position;
• a locking pin that extends from said toggle plate, wherein said locking pin engages said locking groove on said hook plate when said buffer frame moves into said second position from said first position, and wherein said locking pin is free to move in said locking groove when said toggle plate is in said free position and becomes locked in said locking groove when said toggle plate is in said locked position;
• a movable slide rail that selectively moves within said open channel of said fixed slide rail, wherein said movable slide rail engages said toggle plate and moves said toggle plate between said free position and said locked position as said movable slide rail moves toward said first end of said fixed slide rail and away from said first end of said fixed slide rail, respectively.
