Patent ID: 7124902

Claim:
A rack apparatus comprising: a rack body having a plurality of stings extending downwardly therefrom, each of said plurality of stings having a plughole at a bottom end thereof; a slide rest having a generally rectangular shape, said slide rest having a pair of spaced columns extending upwardly therefrom, the columns being received by the plugholes; a compartmental roller rotatably mounted to said slide rest, said compartmental roller having a pair of rollers with a rut therebetween, said pair of rollers having a portion extending downwardly beyond a bottom of said slide rest, said compartmental roller having an axle supporting said pair of rollers and extending through a through hole in said slide rest; a pair of sliding tracks arranged in parallel relation to each other, each of said pair of slide tracks supporting said slide rest and said compartmental roller thereon, each of said pair of slide tracks comprised of a plurality of track segments joined in end-to-end relation, said pair of sliding tracks being affixed by bolts to an underlying surface and supporting said rack body thereon, each of said plurality of track segments connected together by a tongue-and-groove connection, each of said pair of sliding tracks being convex with a convex edge in a center thereof, said rut of said compartmental roller receiving said convex edge therebetween; a blocker affixed at an end of at least one of said pair of sliding tracks so as to stop a movement of said rack body thereon; and a braking mechanism installed so as to be cooperative between said slide rest and said compartmental roller, said braking mechanism comprising a T-shaped plate and an elastic member, said T-shaped plate having a horizontal board positioned outwardly of said slide rest so as to serve as a control button for said braking mechanism, said T-shaped plate having a vertical portion extending through an opening in said slide rest, said axle extending through a through-hole formed in said vertical portion, said vertical portion positioned between said pair of rollers, said vertical portion having a bottom rim having a surface suitable for contacting said convex rim of the sliding rail when said vertical portion is at a first angle, said surface of said bottom rim releasing from said convex rim when said vertical portion is at a second angle, said elastic member positioned between said horizontal board and said slide rest so as to resiliently urge said T-shaped plate to a home position.
