Abstract

See full text

This hanger system for use in window balances features a hanger connected at a lower end of a window balance. The hanger has a carrier interface for connection to the window sash carrier. The carrier has a hanger interface for connection to the hanger. The interfaces are connected and disconnected by a pivoting motion of the hanger with respect to the carrier. Once connected these elements cannot be pulled apart and disconnected by tensile forces without first reversing the assembly steps. A snap connection may also be advantageously added to the hanger and carrier, allowing them to snap together in permanent or non-permanent fashion when fully or partially pivoted into alignment with each other.
