Abstract
A window balance assembly comprising an improved locking carrier mechanism is disclosed. The locking mechanism is actuated when the window sash is tilted. Cam surfaces on the receiver of the mechanism engage cam followers in the clamshell-type housing of the carrier forcing them apart outwardly to lock the carrier in the jamb channel of a window assembly and prevent movement of the carrier in the channel. The receiver incorporates two cams that engage two cam follower surfaces in the housing to improve the distribution of the locking forces of the carrier in the jamb channel. A dual-locking carrier expands in both the axial and lateral directions to contact both front and back surfaces and opposing side surfaces of the jamb channel.
