  • Patent number: 9611688
    Abstract: Windows and secure corner assemblies are generally described. The windows may include a sash having stiles arranged on vertical sides thereof and rails arranged on horizontal sides thereof. Primary reinforcement members may be arranged within the stiles. Secure corner assemblies may be configured to be arranged within corners of the sash formed by intersections of the stiles and the rails. The secure corner assemblies may include at least one secondary reinforcement member arranged on an external surface of one of the rails, such as a top rail. A tilt mechanism may be configured to be coupled to a primary reinforcement member and the at least one secondary reinforcement member, thereby providing a continuous reinforcement connection around the window sash. Vinyl windows using corner assemblies according to some embodiments may have increased pressure ratings compared to vinyl windows that do not include such corner assemblies.
