A system for support of a sash that is laterally removable from between opposed window jambs that uses sash support arms that are movably arranged for transferring the weight of the sash to the shoes and for bridging distances between the sash stiles and the shoes. When not supporting the weight of the sash, the support arms move to positions that allow the sash to be lifted off of counterbalance support shoes and laterally removed from between the window jambs and conversely reinserted between window jambs and lowered onto the shoes. This is done while the shoes are locked in positions within the window jambs. When the support arms support the weight of the sash, they are in positions that rest the sash weight on the counterbalance shoes to support the weight of the sash. The shoes have hooks that can be deployed to lock the shoes reliably in the jambs by engaging projections formed in the jambs for this purpose. In the preferred embodiments, support arm latching members are provided on the hooks in the form of rear extensions that latch over interlock pins extending from the support arms when the hooks are disengaged from the jambs. Thus, the same hook elements that serve to hold the shoes in position when engaged to the jambs serve to further secure the support arms for the sash in position on the shoes when disengaged from the jambs.
Système de support d'un châssis de fenêtre à démontage latéral entre les montants de fenêtre opposés au moyen de bras de support de châssis de fenêtre qui sont disposés de manière amovible pour transférer le poids du châssis de fenêtre aux sabots et combler l'écart entre les montants de châssis de fenêtre et les sabots. Lorsque les bras de support n'appuient pas le poids du châssis de fenêtre, ils passent à des positions qui permettent de soulever le châssis de fenêtre des sabots de support de contrepoids et de le retirer latéralement entre les montants de fenêtre, puis de le réinsérer réciproquement entre les montants de fenêtre et de l'abaisser sur les sabots. Cela se fait pendant que les sabots sont verrouillés dans des positions à l'intérieur des montants de fenêtre. Lorsque les bras de support portent le poids du châssis de fenêtre, ils se trouvent dans des positions qui appuient le poids du châssis de fenêtre sur les sabots de contrepoids pour porter le poids du châssis de fenêtre. Les sabots sont munis de crochets qui peuvent être déployés afin de verrouiller les sabots solidement sur les montants en engageant les projections formées sur les montants à cette fin. Dans les modes de réalisation préférés, des organes de verrouillage du bras de support sont prévus sur les crochets sous forme d'extensions arrière qui verrouillent les goupilles d'interverrouillage s'étendant des bras de support lorsque les crochets sont désengagés des montants. Ainsi, les mêmes éléments de crochet qui servent à tenir place les sabots lorsqu'ils sont engagés avec les montants servent aussi à maintenir en place le bras de support pour le châssis sur les sabots lorsqu'ils sont désengagés des montants.
