Claim:
A drawer expander comprising: (a) a plurality of tray units, each tray unit including (1) a planar surface having a first end which is a front end when said tray units are in use, a second end which is a rear end when said tray units are in use, a longitudinal axis which extends between the first end and the second end, a first side, a second side, a transverse axis which extends between the first side and the second side, (2) a first side wall on the first side of the planar surface, the first side wall extending perpendicular to the planar surface, (3) a second side wall on the second side of the planar surface, the second side wall extending perpendicular to the planar surface, (4) a first end wall on the first end of the planar surface, the first end wall extending perpendicular to the planar surface, and (5) a second end wall on the second end of the planar surface, the second end wall extending perpendicular to the planar surface; (b) each tray unit of said plurality of tray units being oriented in a stacked configuration with each tray unit of said plurality of tray units being larger than a superadjacent tray unit; (c) a tray unit connecting unit which includes (1) a plurality of first connecting arms, (2) a plurality of second connecting arms, (3) a first spring-biased pivot connection connecting each of the first connecting arms to an associated tray, (4) a second spring-biased pivot connection connecting each of the second connecting arms to an associated tray, (5) each spring-biased pivot connection biasing the tray to which it is connected in a direction toward the second end walls of the trays; and (d) at least one tray unit of said plurality of tray units being connected to a support member.
