BOTTOM OFFSET DOOR PIVOT AND SPLINE THRESHOLD An improved bottom offset door pivot is disclosed which comprises an elongated threshold and a door pivot body. The threshold has a keyway formed therein in a direction generally parallel to the axis of elongation of the threshold. The door pivot body has a pivot spindle projecting upwardly therefrom for pivotably mounting a lower portion of a door to the pivot body. The pivot body further has a hook formed thereon configured to mechanically hook into the keyway in the threshold. A flange formed on the lower surface of the pivot body engages a groove formed in the upper surface of the threshold. The flange is disposed relative to the pivot spindle such that when the flange engages the keyway, the pivot spindle is properly offset with respect to the threshold. In the disclosed embodiment, when the lateral edge of the pivot body abuts the vertical door jamb, the pivot spindle is properly offset with respect to the doorjamb. The bottom offset door pivot of the present invention eliminates the necessity for notching the frame and threshold and thereby provides a simple method for securing the offset door pivot to the threshold. The door pivot further provides the advantage that a single pivot may be used for either left- or right-handed doors. |
