A tight-fitting corner construction is provided for use between adjacent, integrally connected parts of a common panel. A specially configured, three-sided miter groove is formed between the panel parts, and the panel is folded to close the groove and to form a corner between the panel parts. An overhanging lip is provided on one of the panel parts along one side of the groove. When the panel is folded to form a corner, the lip is brought into overlying engagement with inner surface portions of the other panel part to effect a thorough, tight-fitting closure of the groove. The panel preferably comprises a hollow, elongated plastic member which is used to form the sides and back of a drawer frame. Snap-acting locking devices are carried in hollow portions of the panel adjacent the corner locations to lock the panel in its folded configuration. A drawer front carries connectors which project into hollow portions of the drawer sides. Button-like locking formations are carried on the connectors and project into holes formed in interior portions of the drawer sides. Neither the snap-acting locking devices nor the drawer front connectors are exposed to view once the drawer construction is completed. Methods of forming panel corner connections and drawer constructions of the foregoing type are also described.
A drawer construction wherein a drawer side formation and a drawer back formation are formed integrally from a single, hollow, extruded plastic member which is folded along a miter-groove at a corner location between the side and back formations to form a corner of a drawer, and including snap-acting locking means carried in hollow portions of a selected one of the side and back formations at the location of a corner to be formed between these formations, the snap-acting locking means being operable when the formations are folded to close the miter groove lying therebetween to engage hollow portions of the other of these formations, for maintaining the folded configuration of these formations.
A drawer construction wherein drawer sides and a drawer back are formed integrally from a single, hollow, extruded plastic member which is folded along miter-grooves at corner locations between the sides and back to form corners of a drawer, and wherein snap-acting locking means are carried in hollow portions of selected of the sides and back at the corner locations, the snap-acting locking means being operable, when the sides and back are folded to close the miter-grooves lying therebetween, to engage hollow portions of the member to maintain the folded configuration of the member, and a drawer front having connectors secured thereto and extending into open ends of the drawer sides for establishing secure connections between the drawer front and the sides, the connectors carrying button-like projections which extend into holes formed in the drawer sides, the holes being formed at locations on the drawer sides which are not visible from either inside or outside the drawer once connections have been completed between the drawer sides and front.
A drawer assembly, comprising:
A drawer construction wherein drawer sides and a drawer back are formed integrally from a single, hollow, extruded plastic member, the member having spaced inner and outer walls extending along its length and defining an elongated channel therebetween, the member having a pair of transversely extending miter grooves severing the inner wall at spaced corner locations, the member having its outer wall folded at both corner locations to bring such portions of the inner wall as define opposite sides of each groove together to form corners between the sides and back, the folded configuration of the member being maintained by snap-acting means carried within the elongated channel at each of the corner locations, the snap-acting locking means being operable to maintain the folded configuration of the member once the member is folded from a relatively flat initial configuration to form corners between the drawer sides and back.
A tight-fitting, integral corner construction between first and second adjacent parts of a panel of the type having inner and outer side surfaces which are substantially flat and parallel, comprising:
