ABSTRACT:
An apparatus, for retaining a sash in a desired open position in a projected window, comprises at least one retaining unit adapted to be mounted on an outer frame, and at least one transforming unit adapted to be mounted within an inner frame. The retaining unit includes a tube-like member adapted to be pivotally connected to the outer frame, and a rod turnably and telescopically received in the tube-like member. The transforming unit is operatively connected to a handle (on the inner frame) and the rod for, in response to angular movement of the handle, turning the rod between a first position in which the rod is prevented from being longitudinally or axially moved relative to the tube-like member and a second position in which the rod is allowed to be longitudinally or axially moved relative to the tube-like member.
