  • Patent number: 6935823
    Abstract: An anchor nut device for attachment to a structure, the device defining a threaded bore for the reception therein of a corresponding member. The device includes an anchor nut which is fabricated from a first material, the nut defining the bore and a plurality of radially extending ears. A base plate is fabricated from a second material, the plate having a first and a second face, the first face cooperating with the plurality of ears. The second face of the plate defines a plurality of dimples for facilitating welding of the plate to the structure. A plurality of arms extend from the plate, such that each ear of the plurality of ears is disposed between a corresponding arm of the plurality of arms and the first face of the plate for capturing the nut relative to the plate. Also, a stop extends from the anchor nut, the stop being disposed between adjacent ears for controlling rotational movement of the anchor nut relative to the plate.

  • Patent number: 6616204
    Abstract: An automotive vehicle door striker plate (10) includes first and second plate parts (22,24) coupled together by an edge flange (26). A continuous slot (28) separates the plate parts except for two bendable portions (30,32). In use, second plate part (24) is welded to a door closing surface in predetermined arrangement then the door has certain manufacturing operations. Next, the door is removed from the body for accessory mounting (e.g., windows). Finally, on reattachment of the door to the body, any reattachment positional adjustment is accomplished by bending the portions (39, 32) by force application.
