  • Patent number: 11187032
    Abstract: In one aspect, a power assist module for covering for an architectural structure may include a spring and a spring shaft extending through the spring. Additionally, the power assist module may include a threaded shaft member coupled to the spring shaft and a drive plug assembly coupled to the threaded shaft member for rotation relative thereto. The drive plug assembly includes a follower member and a separate threaded insert configured to be received within the follower member. The threaded insert is configured to threadably engage the threaded shaft member to allow the follower member to be rotationally coupled to the threaded shaft member in a manner that allows the follower member to move axially along the threaded shaft member as the follower member is rotated relative to the threaded shaft member.
