Abstract

A limit stop assembly for setting a travel limit position of a covering of an architectural-structure covering is disclosed. The limit stop assembly including a first state of operation and a second state of operation. The limit stop assembly being transitioned from the first state of operation to the second state of operation by moving the covering from a first position towards a second position. Transitioning the limit stop assembly from the first state of operation to the second state of operation automatically sets the travel limit of the covering for the second position. In one example of an embodiment, the limit stop assembly includes a screw shaft, a limit nut threadably received on the screw shaft, a hub, and a collar selectively movable between first and second collar positions.

Claims19

Dependent claims

A method for automatically setting a travel limit of an architectural-structure covering, the architectural-structure covering including a central shaft, a rotatable member rotatable relative to the central shaft, a covering coupled to the rotatable member and movable between a first position and a second position via rotation of the rotatable member, and a limit stop assembly movable between a first state of operation and a second state of operation, the method comprising:

providing the covering of the architectural-structure covering in the first position;
moving the covering from the first position towards the second position;
and
upon reaching the second position, moving the covering towards the first position;
wherein moving the covering from the second position to the first position automatically transitions the limit stop assembly from the first state of operation to the second state of operation thus setting the travel limit of the covering at the second position;
wherein in the first state of operation, the limit stop assembly is arranged and configured to enable the covering to be moved from the first position to the second position to set the travel limit of the covering, and in the second state of operation, the travel limit is set.

A method for automatically setting a travel limit an architectural-structure covering, the architectural-structure covering including a covering movable between a first retracted position and a second extended position and a limit stop assembly movable between a first state of operation and a second state of operation, the method comprising:

providing the covering in the first retracted position, the limit stop assembly being in the first state of operation;
moving the covering from the first retracted position towards the second extended position;
and
upon reaching the second extended position, retracting the covering towards the first retracted position;
wherein moving the covering from the second extended position to the first retracted position automatically transitions the limit stop assembly from the first state of operation to the second state of operation thus setting the travel limit of the covering at the second extended position for future subsequent use;
wherein in the first state of operation, the limit stop assembly is arranged and configured to enable the covering to be moved from the first retracted position to the second extended position to set the travel limit of the covering, and in the second state of operation, the travel limit is set.
