Claim:
A two way travel three section slide drawer slide assembly permitting a drawer to be selectively pulled out from opposite open ends of a compartment of a cabinet, comprising in combination: an elongated outer section comprising a flat track threadedly secured to the compartment, and two sets of two projecting stop elements wherein the stop elements of either set are opposite and formed on one of two lengthwise curved edges of the track of the outer section; an elongated intermediate section disposed in the outer section and comprising a flat track, two engaging members at both ends respectively, and two sets of two projecting stop members wherein one set of stop members is proximate to the engaging members at one end, and the other set of stop members is proximate to the engaging members at the other end; two elongated sliding members each slidably disposed either between upper edges of the outer section and the intermediate section or between lower edges of the outer section and the intermediate section wherein each sliding member is limited to travel in a distance between the stop members of one set and the stop members of the other set; an elongated inner section releasably secured to the drawer and comprising a two-end open flat track, an intermediate opening, two positioning members at both ends of the intermediate opening respectively, and two lanced out tabs each spaced from the positioning member; an elongated bearing member disposed between the intermediate section and the inner section; two stop units releasably secured to the engaging members respectively, each stop unit comprising two bent projections on upper and lower edges respectively, two flanges extending from the upper and lower edges respectively but opposing the adjacent projection, each flange including an inclined first surface at one end and an inclined second surface at the other end, and two horizontal sliding members each extending from one edge of the adjacent projection, each sliding member including a cavity at one end; and a flexible limit member comprising an intermediate flat portion adjacent to the intermediate opening, the limiting member further comprising, on each end of the flat portion, a latching member including an inclined surface at one end and an inclined extension at an intermediate portion, a ramp formed on the latching member, a slot abutted on the ramp, and a rectangular cut formed at the other end of the latching member distal the slot; wherein the inner section is secured to the limit member by putting the slots on the positioning members and putting the cuts on the tabs in friction fit respectively; and wherein the drawer is prevented from pulling further either (i) from one end of the compartment when one inclined surface is stopped by the other inclined first surface in a complementary engagement or (ii) from the other end of the compartment when the other inclined surface is stopped by one inclined first surface in a complementary engagement.
