Pull-out guide for drawers

A pull-out guide assembly for use on each of opposite sides of a drawer in an article of furniture of the type wherein a drawer is slidably insertable into and removable from a furniture body, said pull-out guide assembly comprising:

• a supporting rail and a pull-out rail adapted to be mounted on adjacent sides of the body and the drawer at positions to extend substantially horizontally and to be relatively longitudinally movable when the drawer is pushed into or pulled out from the body, said supporting rail and pull-out rail having respective vertically spaced and horizontally extending flanges;
• at least two roller means, positioned for rolling contact on said horizontally extending flanges, for taking up vertical forces between said pull-out rail and said supporting rail when the drawer is positioned within the body;
• said roller means being mounted within and supported by a carriage which is longitudinally movable with respect to said supporting and pull-out rails, said carriage comprising a single rigid and inflexible member extending longitudinally of said supporting and pull-out rails, said carriage and said rails being dimensioned such that said carriage is unitarily and completely tiltable in a single direction with respect to said rails about a horizontal axis transverse to the longitudinal direction of said rails only when said supporting rail and said pull-out rail are relatively longitudinally moved to a maximum drawer pull-out position;
• plural locking means staggered in said longitudinal direction for locking said carriage in one of said rails when said rails are moved to said maximum drawer pull-out position, each said locking means comprising a projection and aperture provided on said carriage and said one rail in relative positions such that said projection extends into said aperture when said carriage is tilted about said axis;
• and
• said one rail having at an inner end thereof, with respect to the direction of movement of the drawer, stop means for limiting the relative longitudinal movement between said carriage and said one rail.
