Abstract
In various aspects, a covering for an architectural structure includes a bottom rail assembly that can be efficiently and effectively assembled during manufacturing of the covering. Specifically, in one embodiment, the bottom rail is configured such that one or more operating system components of the covering can be mounted within and directly supported by the bottom rail. In addition, a separate cover may be coupled to the bottom rail during the assembly process.
Claims11
A covering for an architectural structure, said covering comprising:
- a headrail assembly;
- a bottom rail assembly supported relative to said headrail assembly via one or more lift cords, said bottom rail assembly comprising:
- a bottom rail including a top wall extending along a top side of said bottom rail, said bottom rail further including opposed first and second sidewalls extending from said top wall along respective first and second sides of said bottom rail towards a bottom side of said bottom rail, said top wall of said bottom rail defining at least one mounting aperture;
- a lift system positioned within an interior of said bottom rail and operable to raise and lower said bottom rail assembly relative to said head rail assembly by adjusting an effective length of said one or more lift cords extending between said headrail and bottom rail assemblies, said lift system including at least one system component, said at least one system component comprising at least one mounting element configured to be inserted into said at least one mounting aperture, said at least one mounting element and said at least one mounting aperture being configured to provide a snap-fit connection between said system component and said top wall of said bottom rail;
- and
- a user actuatable component positioned relative to one of said first sidewall or said second sidewall along an exterior of said bottom rail, said user actuatable component configured to be actuated to control an operation of said lift system,
- wherein:
- said at least one mounting element comprises a first mounting element and a second mounting element, said first mounting element being sized or shaped differently than said second mounting element;
- said at least one mounting aperture comprises a first mounting aperture and a second mounting aperture, said first mounting aperture being sized or shaped differently than said second mounting aperture;
- and
- said first mounting element is configured such that said first mounting element can only be inserted through one of said first mounting aperture or said second mounting aperture when installing said system component relative to said top wall of said bottom rail.

A covering for an architectural structure, said covering comprising:
- a headrail assembly;
- a bottom rail assembly supported relative to said headrail assembly via one or more lift cords, said bottom rail assembly comprising:
- a bottom rail including a first sidewall and a second sidewall, said first sidewall extending along a front side of said bottom rail between opposed top and bottom sides of said bottom rail and said second sidewall extending along a rear side of said bottom rail between said opposed top and bottom sides, said bottom rail further including a third wall extending between said first and second sidewalls along one of said top side or said bottom side of said bottom rail and first and second rail retention elements provided in operative association with said first and second sidewalls, respectively;
- a separate cover configured to be coupled to the bottom rail such that said bottom rail and said cover at least partially define an interior volume of said bottom rail assembly, said cover including first and second cover retention members configured to be snapped into position relative to said first and second rail retention elements, respectively, of said bottom rail to secure said cover to said bottom rail;
- and
- a lift system comprising least one system component mounted to one of said third wall of said bottom rail or said cover such that said at least one system component is supported within said interior volume of said bottom rail assembly by said one of said bottom rail or said cover;
- wherein:
- said one of said third wall of said bottom rail or said cover defines a first mounting aperture and a second mounting aperture, said first mounting aperture being sized or shaped differently than said second mounting aperture;
- said at least one system component comprises a first mounting element and a second mounting element, said first mounting element being sized or shaped differently than said second mounting element;
- said first and second mounting elements and said first and second mounting apertures are configured to provide a snap-fit connection between said system component and said one of said third wall of said bottom rail or said cover;
- and
- said first mounting element is configured such that said first mounting element can only be inserted through one of said first mounting aperture or said second mounting aperture when installing said system component relative to said bottom rail.
