A window having a frame with at least two oppositely disposed side members, a top member, and a bottom member. Operably connected to each frame side member is a jamb liner having a front face and at least one jamb channel. Mounted within the frame is at least one sash having two oppositely disposed sides. The sash tilts away from the frame for easy cleaning. Within each jamb channel is a locking slide block for slidably and rotatably mounting the sash to the frame. A plough extends from the face of each jamb liner in the direction of the opposite frame side member. Each side of the sash has a sash groove for slidably mounting the sash in the frame by receiving adjacent ploughs. The plough and sash grooves have interlocking edges which engage to resist unintentional tilting of the sash. The jamb liner is mounted for lateral displacement from a first position wherein the plough is engaged with a sash groove to a second position wherein the plough is at least partially retracted from the groove so that the window can be tilted. There is a counterbalance operatively connected to the frame which has a counterbalance tab with an elongated portion having a flange proximate one end for connecting the counterbalance to the locking slide block.

Double-hung tilting sash type window system

The present invention is directed to a locking slide block slidably and pivotably mounting a window sash to a side member of a window frame having a vertical jamb channel. The locking slide block has a housing with oppositely disposed sliding surfaces for guiding the housing in the jamb channel. Operably connected to the housing is a locking means for selectively engaging the jamb channel and locking the housing in a fixed position, and a cam for selectively operating the locking means. A sash pivot operatively connected to the cam is operably connectable to the sash. The housing also has a sash pivot retainer spring. A retaining means is utilized to protect a free second end of the retainer spring from bowing and deforming due to forces applied to the window sash in operation.

Locking slide block

The present invention is directed at a locking slide block for slidably and pivotally mounting a window sash to a side member of a window frame having a vertical jamb channel. The window pivot has a housing with oppositely disposed sliding surfaces for guiding the housing in the jamb channel. Operably connected to the housing is a locking spring for selectively engaging the jamb channel and locking the housing in a fixed position. A sash pivot is operably connected to the sash and to the housing. The housing also has a sash pivot retainer spring. The pivot and housing have flanges to prevent the pivot from being pulled away from the housing proximately parallel to the longitudinal axis of an elongated portion of the pivot.
