A support system for a heavy sash that is laterally removable from between opposed window jambs includes a pair of sash support arms pivotally mounted on each sash stile and counterbalance shoes that engage the support arms to uphold the sash. The support arms, in inwardly dependent positions, can engage the shoes as a sash is lowered onto the shoes; and the support arms, in outwardly extending positions, support the weight of the sash on the shoes. Hooks dependent from the shoes can lock the shoes to the jambs during sash removal or replacement; and the sash support arms, the shoes, and the hooks are all preferably cut from metal extrusions.

Cette invention concerne un système de supportage pour châssis lourd qui peut être retiré par le côté de son emplacement entre montants opposés d'un cadre de fenêtre. Il comprend une paire de bras de supportage montés à pivot sur les deux montants du châssis et de patins d'équilibrage qui reçoivent les bras de soutien pour retenir le châssis. Les bras de supportage, lorsqu'ils sont orientés vers l'intérieur, peuvent prendre appui sur les patins à l'abaissement du châssis vers ces derniers et, lorsqu'ils sont orientés vers l'extérieur, ils transfèrent le poids du châssis sur lesdits patins. Des crochets fixés aux patins permettent de verrouiller ceux-ci aux montants à l'enlèvement ou au remplacement du châssis. Tous ces éléments, bras de supportage, patins et crochets, sont de préférence découpés de profilés métalliques.
