Abstract
Various aspects of the disclosure relate to modular sill systems for sliding panel doors and windows, collectively “sliding fenestration units.” In various examples, modular sill systems include multiple separate and distinct base components that provide tracks on which one or more panels are able to slide.
Claims15
A modular sill system for multiple sliding panels, the system comprising:
- a base member having a first end and a second end;
- a first sill frame element affixed to the base member;
- a second sill frame element, distinct from first sill frame element, affixed to the base member;
- a support member extending from the base member and arranged between the first sill frame element and the second sill frame element;
- and
- at least one cover component coupled to the first sill frame element and the second sill frame element that is configured to conceal a space between the first sill frame element and the second sill frame element.
A fenestration unit including a modular sill system for multiple sliding panels, the fenestration unit comprising:
- a first sliding panel and a second sliding panel;
- a base member having a first end and a second end;
- a first sill frame element affixed to the base member and forming a track upon which the first sliding panel slides;
- a second sill frame element, distinct from first sill frame element, affixed to the base member and forming a track upon which the second sliding panel slides;
- a cover component releasably coupled to the first sill frame element and the second sill frame element to cover a space between the first sill frame element, the second sill frame element and the base member.
A method of manufacturing a modular sill system for multiple sliding panels, the method comprising:
- affixing a first sill frame element to the base member;
- affixing a second sill frame element, distinct from first sill frame element, to the base member;
- arranging a support member in contact with the base member and between the first sill frame element and the second sill frame element;
- and
- coupling a cover component to the first sill frame element and the second sill frame element.
