ADJUSTABLE SILL AND THRESHOLD ASSEMBLY

摘要

ADJUSTABLE SILL AND THRESHOLD ASSEMBLY An adjustable sill and threshold assembly in which the stationary sill includes a one-piece, molded base having a metal clad tread portion and a threshold portion having a groove extending longitudinally thereof. An adjustable threshold overlies the groove and has downwardly extending legs received in the groove with a pair of legs extending along an outer edge of the threshold cooperating with an upstanding leg formed by one edge of the metal cladding to form a labrynth seal against the entry of dirt and moisture into the groove. Moisture which may enter the groove along its opposite, inner edge or by condensation, can escape through drainage channels which extend from the groove to a collection chamber formed along the outer edge of the sill. The adjustable threshold is moved vertically by actuators which are slidably received in the groove and have inclined ramps cooperating with inclined ramps on inner surfaces of the legs of the threshold. The actuators are interlocked with portions of the groove and with the inclined ramps on the threshold to prevent separation of the threshold from the sill during adjustment, and a tool engaging portion of the actuators extends upwardly for engagement by a suitable tool to permit the actuators to be positioned longitudinally of the groove as required to provide the desired adjustment of the threshold.
