CORDLESS BLIND SYSTEM AND RETRO-FIT METHOD

摘要

An enclosed drive system for use in conjunction with a lift cord extending from a headrail of an architectural cover. The enclosed system encases and engages the lift cord with a drive mechanism within the enclosure, thereby avoiding hazardous loops. A method for retro-fitting an architectural cover lift cord assembly including a lift cord associated with a cord lock and extending from a headrail of the architectural cover is also described, for modifying the architectural cover to eliminate hazardous loops therefrom. Also disclosed in this disclosure is a cord lock mechanism that pinches the cord, a handle that actuates the cord lock mechanism, and a driving mechanism having a cord guide that engages the cord and a slider that slides along the handle to actuate the cord while the cord is enclosed within an enclosure defined by the handle.

主权项

1. A drive system for use in conjunction with one or more lift cords extending from a headrail of an architectural cover, said drive system comprising:
an enclosure adapted to conceal at least a portion of at least one lift cord; a first drive mechanism in the enclosure, adapted to engage the at least one lift cord, and coupled to a handle mechanism for manual operation; a bracket adapted to connect the enclosure to the headrail of an architectural cover; and a cord lock disablement mechanism for disabling a cord lock of the architectural cover.
