  • Patent number: 5951133
    Abstract: A drawer head which is readily removable and replaceable from the front of a conventional drawer body is disclosed. The drawer head generally takes the form of a rectangular cover panel sized to cover the front panel of a drawer body. An arcuate handle extends outwardly along the top of the cover panel for allowing a user to easily grip the drawer head in order to slide the drawer in and out of a cabinet. The drawer head includes an elongated slot extending substantially between the sides of cover panel and being adapted to receive a header flange of a drawer body. To attach the drawer head to a conventional drawer body, the header flange of the drawer body is inserted through the elongated slot so that the header flange supports the drawer head with the drawer head in a contiguous relationship with the front panel of the drawer body. Fasteners are then used to secure the bottom of the drawer head to the drawer body.
