1. A drawer slide assembly comprising:
a first drawer slide member having opposing first and second ends, said first drawer slide member having a first pair of spaced-apart stopper elements disposed proximate the first end of first drawer slide member and a second pair of spaced-apart stopper elements disposed between the first pair of stopper elements and the second end of the first drawer slide member, a first stopper element of the first pair of stopper elements being spaced from a second stopper element of the first pair of stopper elements by a distance that is substantially equal to a distance by which a first stopper element of the second pair of stopper elements is spaced from a second stopper element of the second pair of stopper elements;
a first roller mechanism having a substantially flat, rectangular body portion comprising two opposing ends and opposing first and second sides, and having a roller associated therewith; said first roller mechanism having a first leg portion extending substantially perpendicular from one end of the body portion, and having a roller associated therewith; and a second leg portion extending substantially perpendicular from the opposite end of the body portion, and having a roller associated therewith;
a first pair of spring arms extending from the first side of the body portion of the first roller mechanism, and a second pair of spring arms extending from the second side of the body portion of the first roller mechanism, said first roller mechanism being rollingly supported on the first drawer slide member between a first position of the first roller mechanism with a first spring arm of the first pair of spring arms of the first roller mechanism aligned to abut the first stopper element of the first pair of stopper elements and a second position of the first roller mechanism with a first spring arm of the second pair of spring arms of the first roller mechanism disposed directly opposite the first spring arm of the first pair of spring arms of the first pair of spring arms aligned to abut the second stopper element of the first pair of stopper elements;
a second roller mechanism having a substantially flat, rectangular body portion with opposing first and second sides and a first pair of spring arms extending from the first side of the body portion of the second roller mechanism and a second pair of spring arms extending from the second side of body portion of the second roller mechanism, said second roller mechanism being rollingly supported on the first drawer slide member between a first position of the second roller mechanism with a first spring arm of the first pair of spring arms of the second roller mechanism aligned to abut the first stopper element of the second pair of stopper elements and a second position of the second roller mechanism with a first spring arm of the second pair of spring arms of the second roller mechanism disposed directly opposite the first spring arm of the first pair of spring arms aligned to abut the second stopper element of the second pair of stopper elements; and
a second drawer slide member rollingly supported on the first and second roller mechanisms.
