US 11,459,822 B2 · Tilt-control assembly for use with an operating mechanism in an architectural-structure covering

Abstract

A tilt-control assembly for use with an operating mechanism of an architectural-structure covering is disclosed. The tilt-control assembly includes a limiter having an external screw thread and a ball operatively associated with the screw threads so that rotation of the limiter moves the ball relative to the limiter. The screw threads may include variable pitch threads. For example, the screw thread may include a middle thread pitch in a middle portion of the screw thread and an end thread pitch adjacent to the ends of the screw thread, the middle thread pitch being smaller than the end thread pitch. In addition, the limiter and/or screw threads may include a variable diameter. The ball may be positioned within a groove including a contoured surface that substantially corresponds to the variable diameter. The ends of the screw thread may include substantially spherically shaped end portions for receiving the ball therein.

Dependent claims

A tilt-control assembly for use with an operating mechanism of an architectural-structure covering, the tilt-control assembly comprising:

a limiter having an external screw thread, said screw thread extending from a first end to a second end, the screw thread including a middle portion positioned between said first and second ends;
and
a ball operatively associated with said external screw thread so that rotation of said limiter moves said ball relative to said limiter;
wherein said screw thread includes variable pitch threads;
and
wherein said screw thread includes a variable minor diameter such that said screw thread has a first minor diameter in said middle portion and a second minor diameter adjacent to said first and second ends, said second minor diameter being larger than said first minor diameter.

A horizontally-extending architectural-structure covering comprising:

a head rail assembly including a control system;
a covering operatively coupled to said control system, said covering being movable between an extended position and a retracted position, and said covering being pivotable between an open configuration and a closed configuration;
an operating mechanism for actuating said control system to move said covering between said extended position and said retracted position, and for pivoting said covering between said open and closed configurations;
and
a tilt-control assembly for controlling an amount of pivoting of said covering, said tilt-control assembly including:
a limiter having an external screw thread, said screw thread extending from a first end to a second end, the screw thread including a middle portion positioned between said first and second ends;
and
a ball operatively associated with said external screw thread so that rotation of said limiter moves said ball relative to said limiter;
wherein said screw thread includes variable pitch threads;
and
wherein said screw thread includes a variable minor diameter such that said screw thread has a first minor diameter in said middle portion and a second minor diameter adjacent to said first and second ends, said second minor diameter being larger than said first minor diameter.
