The lightweight drawer support assembly of the present invention includes a plurality of drawers each having an open frame and a depending flexible compartment. In a closed condition, the drawers are supported in a hollow rectangular frame in vertically stacked alignment on upstanding front and rear fixed drawer support posts. In an open condition out of the hollow interior of the frame, any one of the drawers is supported on its front end by the upstanding fixed front drawer support posts, and on its rear ends on upstanding movable rear drawer support posts slidably mounted to the sides of the hollow frame for movement in a direction generally transverse to their long axes. The upstanding movable rear drawer support posts have a plurality of vertically spaced rearwardly extending projections that yoke and support corresponding laterally and outwardly extending shoulder portions at the rear of the drawers. A plurality of latching arms are rotatably mounted eccentrically to the upstanding fixed rear drawer support posts in registration with the lower rearwardly extending projections and are cooperative therewith to latch the drawers in the closed condition in response to any drawer being in an open condition.

The drawer assembly of claim 6, further including fifth means coupled to said upstanding movable rear drawer support posts for returning said upstanding movable rear drawer support posts from an open to a closed condition. 8. The drawer assembly of claim 7, wherein said fifth means includes loops of VELCRO slidably mounted loosely between upper and lower rearwardly extending projections, and complementary VELCRO strips pivotably mounted to the confronting faces of said laterally and outwardly extending shoulders. 9. The drawer assembly of claim 4, wherein said third means includes a plurality of latching arms rotatably mounted eccentrically on confronting lateral faces of said upstanding fixed rear drawer support posts proximate said horizontally extending channels. 10. The drawer assembly of claim 9, wherein said latching arms include a bevelled surface on the ends thereof closest to the axis of eccentric rotation. 11. The drawer assembly of claim 4, wherein the lateral and outwardly extending shoulders have bevelled alignment surfaces. 12. The drawer assembly of claim 1, further including a flexible cover removably mounted to the open top, and to the open sides, of said frame. 13. The drawer assembly of claim 7, further including sixth means for removably retaining said upstanding rear drawer support posts in said closed condition thereof. 14. The drawer assembly of claim 13, wherein said sixth means includes first and second loops of VELCRO, said first loop mounted to said upstanding movable rear drawer support post, and said second loop mounted to said upstanding fixed rear drawer support post.
