Claim:
A drawer slide comprising: a first slide member; a second slide member which is slidably extensible from within the first slide member, from a rearward position to a forward position; a third slide member which is slidably extensible from within the second slide member from a retracted position to an extended position relative to the second slide member; a staging lock having a forward end, a rearward end, a central portion, a follower tab extending from said forward end toward the first slide member, and a lock tab extending from said forward end toward the third slide member; the staging lock further comprising a spring relief space formed into a side of said staging lock to define a relief surface which is spaced apart from said side by a relief edge; a mounting boss extending between said central portion of said staging lock and a web portion of the second slide member, wherein said mounting boss rotatably secures said staging lock to the web portion of the second slide member, such that said staging lock is moveable between an open position and a closed position; a bias spring having opposite end portions, one of said end portions engaging the second slide member and an other of said end portions secured to said staging lock, wherein said opposite end portions of said bias spring are spaced apart from said mounting boss, on opposite sides of said mounting boss; said spring relief space receiving said bias spring to enclose at least said opposite end portions of said bias spring between said relief surface and the web portion of the second slide member; said third slide member including a staging lock catch for engaging said lock tab to secure said third slide member in fixed relation to said second slide member as said third slide member is moved from the extended position into the retracted position; and said first slide member including an actuating cam which engages said follower tab and rotates said staging lock from said closed position to said open position, such that said lock tab is moved away from engaging said staging lock catch and the third slide member is released for moving from the retracted position toward the extended position.
