Abstract
A threshold assembly includes a unitary compression molded plastic composite body formed to define an upwardly open threshold cap channel, jamb boots at its ends, and a support substrate outboard of the channel. An extruded aluminum sill plate is snapped into place on the plastic body and a vertically adjustable threshold cap is disposed in the upwardly open channel. Drain channels may be formed in the plastic body to direct water outwardly and away from the threshold assembly. The plastic body forms a stable foundation that will not rot, swell, or rack in the presence of moisture and fabrication of the assembly is greatly simplified as compared to traditional threshold assemblies.
Claims28
A threshold assembly for spanning bottoms of vertical jambs of an entryway, said threshold assembly comprising:
- an elongated unitarily molded body defining an upwardly open channel along an inside edge portion and a support substrate projecting outwardly from said channel to an outside edge;
- a sill plate attachment slot formed in said elongated body;
- a sill plate mounted on said body covering and supported by said support substrate, said sill plate having an outside edge portion profiled to fit over said outside edge of said support substrate, and an inside edge;
- said molded body being formed with an upstanding nosing along said inside edge portion, said nosing forming an inside wall of said upwardly open channel;
- said sill plate being formed with a vertical wall along its inside edge, a first portion of said vertical wall extending downwardly to engage with said sill plate attachment slot to secure said sill plate to said body and a second portion of said vertical wall extending upwardly to define a dam;
- and
- a threshold cap disposed in said upwardly open channel for underlying a closed door.
A threshold assembly comprising:
- a unitarily molded body defining an elongated upwardly open channel from which a support substrate extends outwardly to an outside edge;
- an attachment slot formed along said molded body;
- a sill plate mounted on said molded body covering and supported by said support substrate, said sill plate having an outside edge portion disposed along said outside edge of said support substrate and an inside edge portion formed with a vertical wall;
- said vertical wall defining an outside wall of said upwardly open channel and having a downwardly projecting portion disposed in said attachment slot holding said sill plate in place on said body and an upwardly projecting portion forming a dam;
- and
- a threshold cap disposed in said upwardly open channel.
