摘要：Counterbalance mechanisms for a vertically movable sash have componentsextending downward within guides on which the sash moves. The guides can movelaterally of the sash to allow the sash to tilt and be removed from the window, and thecounterbalance components are arranged within the guides to accommodate such lateralmovement. Slots in the guides accommodate interconnections between counterbalancecomponents within the guides and the sash running vertically against outward surfaces ofthe guides, and these interconnections also allow lateral movement of the guides andtilting of the sash. The guides are mounted on window jambs by resilient elements thatbias the guides into engagement with sash grooves and also accommodate lateralmovement of the guides out of the sash grooves, to allow the sash to tilt.
