Abstract
An assembly for a door or window frame including an elongated sill and a corner key attached to each end of the sill. The corner key includes a water chamber for collecting water therein and a plurality of ports for diverting water from the water chamber outwardly through a drain port. The water chamber and plurality of ports are designed to temper a high-pressure gradient in the sill and effectively promote water egress away from the sill.
Claims20
A method of assembling a door or window frame, comprising:
- providing an elongated sill having a first end and an opposite second end, the sill including a first chamber, a second chamber, and a third chamber, the first chamber operable for collecting and storing water entering the sill;
- and
- providing a corner key having a sill-facing surface;
- and
- coupling the corner key to the sill along the sill-facing surface, the corner key comprising:
- a first port formed along the sill-facing surface, the first port defining a first passage between the first and second chambers of the sill for allowing water to flow from the first chamber to the second chamber;
- a second port formed along the sill-facing surface and offset from the first port, the second port defining a second passage between the second chamber and the third chamber of the sill for allowing water to flow from the second chamber to the third chamber;
- and
- a drain in communication with the third chamber and operable to direct water from the third chamber out of the corner key.
6 more elements
A method of manufacturing a corner key for a sill assembly comprising:
- forming a first face of the corner key with a port formed into and along the first face, the first face configured to face and couple to a sill of the sill assembly with the port fluidly connecting a first chamber of the sill and a second chamber of the sill, the port defining a first passage allowing water to flow from the second chamber to the first chamber;
- forming a second face of the corner key with a chimney vent having a first vent opening in communication with the port, the chimney vent operable to divert air and water ingress entering the port, the chimney vent having a second vent opening formed along the second face of the corner key that is configured to face away from the sill;
- and
- forming a channel along the second face of the corner key, the channel in communication with the second vent opening of the chimney vent, the channel including one or more walls arranged for collecting water moving through the chimney vent and the channel.
