Abstract
The specification disloses an automobile molding with an integral connector protruding from the inner surface of the molding. The connector has a central core opening and a transverse securing slot having a wall which cants away from the inner surface of the molding as the slot extends toward the central opening thereby facilitating removal of a core pin used in molding the connector and simplifying the mold and the molding operation.
Claims8
An automobile molding comprising:
- an elongated molded plastic strip having an outer surface for facing away from an automobile and an inner surface for facing toward an automobile;
- and
- at least one elongated molded plastic connector extending outward from said inner surface to an outward extremity spaced away from said inner surface for coupling said automobile molding to the automobile, said connector having a longitudinal central core opening extending from said extremity inwardly into said connector towards said inner surface of said strip, generally along the longitudinal axis of said connector, and a transverse slot extending along at least one side of said connector transverse to its longitudinal axis and defining an oppening from the exterior of said connector into said central core opening, said transverse slot including an inner edge wall located towards said inner surface of said strip and an outer edge wall spaced from said inner edge wall in a direction away from said inner surface of said strip, said outer edge wall of said transverse slot being a canted wall, said canted wall canting outward with respect to said inner surface of said strip as said canted wall extends from the exterior of said connector into said central core opening, thereby facilitating removal of a single piece mold portion, for forming said central core opening and said transverse slot, from said central core opening and said transverse slot and facilitating engagement of said connector to the automobile.
An integral, single piece automobile molding formed by injection molding comprising:
- an elongated molding strip having an outer surface for facing away from an automobile and an inner surface for facing toward an automobile;
- an elongated, cylindrical connector extending outward from said inner surface to an outer extremity for coupling said automobile molding to the automobile, said connector having a longitudinal, cylindrical, central core opening, a pair of circumferentially spaced, transverse slots radially opposed to one another, extending partially around the circumference of said connector from one lateral extremity to another and each having an inner edge wall spaced towards said inner surface of said strip and an outer canted edge wall spaced away from said inner edge wall and said inner surface of said strip, said canted walls canting outward with respect to said inner surface of said strip as said canted walls extend from the exterior of said connector into said central core opening, a pair of radially opposed longitudinal slots, extending longitudinally from said outward extremity of said connector toward said inner surface, each longitudinal slot circumferentially located between said lateral extremities of said circumferentially spaced transverse slots, and a pair of front tapered surfaces at the outward extremity of said connector, said tapered surfaces tapering outward in a direction away from said outward extremity towards said inner surface of said strip to reduce the transverse dimension of said connector at said canted wall, each tapered surface being defined by the intersection of an inclined plane with a portion of said cylindrical connector between said longitudinal slots.
