Abstract: The invention relates to a cassette (1) intended for building up drawer cabinets, a drawer (2) being included in the cassette. In order to carry and guide the drawer (2) inside the cassette (1), a rail (24) made of plastic is arranged on each side of the cassette, said rail being mountable on a lower flange (10) projecting inwards from each side wall (7, 7′) of the cassette. From the top side of the rail, a longitudinal ridge (29) protrudes, which is distanced from an outside pressable against the side wall of the cassette with a distance which in the main corresponds to half the difference between the width of the cassette and the width of the drawer, and the rail at opposite end portions having similar ramp surfaces (35), which are oblique in the direction upwards/inwards from the ends of the rail towards the plane top side of the rail. In this way, one and the same rail is, in a universal way, mountable either to the right or to left in the cassette.

Abstract: This invention relates to a cassette (1) intended for building up drawer cabinets, in which a drawer (2) having a frontal piece (18) is included, a lock (22) is included in the drawer for locking of the same in the cassette. According to the invention, the lock (22) includes a house (23) located inside the frontal piece (18) of the drawer and in connection with an opening (44) therein, inside which house there is a spring-loaded plunger (25), which is movable vertically in relation to a hole (45) in a bottom piece (19) of the drawer, viz. between a lower, locking position in which a free end of the plunger (25) is behind and below an upper edge of a flange (16) in a frontal frame of the cassette, and an upper, opening position in which the free end of the plunger is located above the flange (16) and goes free therefrom. By the location thereof in the bottom part of the drawer, the lock guarantees that heavily loaded thereby deformed drawers do not risk to unintentionally be pulled out from the cassette.
