Abstract
A shutter set includes a first vane and a first vane stop. The first vane is moveable between a first position and a second position. The first vane stop is selectively moveable between a locking position and a free position, relative to the first vane. The first vane stop is configured to apply a bias force or is configured to bias the first vane by a predetermined clearance distance when the first vane stop is in the locking position, and is configured to allow movement of the first vane between the first position and the second position when the first vane stop is in the free position.
Claims15
A shutter set comprising:
- a first vane moveable between a first position and a second position;
- a second vane moveable between a first position and a second position;
- a first vane stop selectively moveable relative to the first vane between a locking position and a free position, wherein the first vane stop includes:
- a first flexible connector configured to bias the first vane by a predetermined clearance distance when the first vane stop is in the locking position;
- a second flexible connector configured to bias the second vane by the predetermined clearance distance when the first vane stop is in the locking position;
- and
- wherein the first vane stop is configured not to bias the first vane when the first vane stop is in the free position and configured to allow movement of the first vane between the first position and the second position when the first vane stop is in the free position.
A shutter set comprising:
- a first vane set moveable between a first position and a second position;
- a second vane set moveable between a first position and a second position;
- and
- a vane stop selectively moveable relative to the second vane set between a locking position and a free position, wherein the vane stop is configured to apply a bias force to the second vane when the vane stop is in the locking position;
- a first actuator operatively attached to the first vane set, and operatively attached to the vane stop, wherein the first actuator is configured to drive the first vane set between the first position and the second position, and is configured to drive the vane stop between the locking position and the free position;
- and
- a second actuator directly connected to the second vane set and configured to drive the second vane set between the first position and the second position.
