SIDE LOAD CARRIER AND BALANCE SYSTEM FOR WINDOW SASHES

摘要

A carrier assembly consisting of a carrier, a carrier encasement and a sash latch. The carrier is secured to the end of one or more balances, including spiral rod and block and tackle balances. The weight of the sash is borne by a platform on the carrier. The undesired vertical forces exerted by the balance on the carrier is thereby translated into a force urging the carrier toward the sash until firm contact is made between the carrier encasement and the side of the sash. The translation of the torsional force into a side directed force eliminates or substantially reduces the friction that might otherwise have existed between the carrier and the jamb channel caused by the undesired vertical forces exerted by the balance on the carrier.
