Abstract
A drawer side wall of aluminum includes a vertical flange forming the lateral limitation of a drawer, a lower fastening flange for attachment of the bottom of the drawer and an upper horizontal running flange for a supporting roller to be mounted on the body of an article of furniture. At the front end of the drawer side wall, the vertical flange has formed therein a deformation positioned below an oblique or inclined portion of the running flange. The profile of the side wall of aluminum is injection molded or extruded. After such operation, the front end of the vertical flange of the drawer side wall is impressed to form the deformation, and thus, the horizontal flange is bent upwards.
Claims16
A drawer side wall for incorporation into a drawer to be mounted for sliding movement into and out of the body of an article of furniture, said drawer side wall having upper and lower sides and forward and rearward ends and comprising:
- a vertical flange to define a lateral limit of the drawer;
- a lower fastening flange extending laterally from a lower portion of said vertical flange and to be used for attaching said drawer side wall to a bottom of the drawer;
- an upper horizontal running flange extending laterally from an upper portion of said vertical flange and to run on a support roller to be mounted on the body of the article of furniture;
- said vertical flange, said lower fastening flange and said upper running flange comprising an integral and unitary metal structure resulting from the injection molding or extrusion of said metal;
- said vertical flange having formed therein, adjacent a forward end thereof, a recess;
- said upper running flange having a forward portion inclined upwardly toward a forward end thereof;
- and
- said upwardly inclined forward portion of said upper running flange resulting from upward deformation of the metal of said vertical flange above said recess upon the formation of said recess by mechanical deformation into said vertical flange.
A process for manufacturing a drawer side wall for incorporation into a drawer to be mounted for sliding movement into and out of the body of an article of furniture, said process comprising:
- forming by injection molding or extrusion an integral and unitary metal structure including a vertical flange to define a lateral limit of the drawer, a lower fastening flange extending laterally from a lower portion of said vertical flange and to be used for attaching said drawer side wall to a bottom of the drawer, and an upper horizontal flange extending laterally from an upper portion of said vertical flange and to run on a support roller to be mounted on the body of the article of furniture;
- and
- mechanically deforming said vertical flange at a position adjacent a forward end thereof to thereby form a recess in said vertical flange, and thus deforming upwardly the metal of said vertical flange above said recess by an amount sufficient to cause a forward portion of said upper running flange to incline upwardly toward a forward end thereof.
