Adjustable internal double limit stop for roller shades
Adjustable Internal Double Limit Stop for Roller Shades Abstract An architectural covering assembly (100) includes a rotatable roller tube (104), a covering (106) coupled to the rotatable roller tube (104), and first and second limit screws (124, 126) each having respective first and second ends. The second end (148) of the first limit screw (124) can engage the first end (152) of the second limit screw (126). One of the limit screws is rotationally and axially fixed with respect to an end plate (122). The other of the limit screws is movable between rotationally locked and rotationally unlocked positions with respect to the end plate (122). Limit nuts (128, 130) are threadably coupled to external threads of the limit screws. In the rotationally locked position the one of the limit screws is axially and rotationally fixed with respect to the end plate (122), and in the rotationally unlocked position the other of the limit screws is rotationally movable with respect to the end plate (122) to adjust an extension or retraction limit of the covering (106).
