摘要

The guide for a drawer pulled out to its full extent consists of a rail (6) on the main piece of furniture; a rail (7) on the drawer; and a rail (8) between them. The drawer-rail is connected by cogging to a cog wheel's (23) outer cogging (24, 26). Between the middle rail (8) and the small-diameter cog-wheel is cogging (26, 27). The inward-pointing cogging (27) of the middle rail engages with the cog-wheel's outer cogging (26). The middle rail rolls on a small diameter roller (5) which, with the cog-wheel, is in two parts, rotating on the same axle. ADVANTAGE - When the drawer is pulled right out, there is no slippage between the middle rail and the rails on the drawer and furniture.
