The drawer rail system comprises two rails (20) attached to the carcass, two rails (10) attached to the bottom of the drawer and two intermediate rails (30). Two wheels (41, 41') are mounted at the front end of each intermediate rail whose axes are at equal angles to the horizontal, but in opposite directions, two similar wheels (43, 43') halfway down it and a single upright roller (42) at its back end. A similar roller (44) is mounted halfway down it. The rail attached to the drawer has surfaces bent to cooperate with the front set of sloping and upright wheels while the rail attached to the carcass has similar surfaces which cooperate with the middle wheels. |
