Disclosed is a fixed frame or opening frame, resulting from an assembly of joinery profiles, forming the mullions and the cross-members of the frame, with the profiles of the mullions and the cross-member profiles being assembled by their ends. The frame includes at least one device for compressing, including at least one mechanical connection extending interiorly along an intermediary portion of the frame, the at least one mechanical connection connecting by its ends of supports of the device for compressing, the supports being integral respectively with mullions or cross-members, on either side of the intermediate portion of the frame, the mechanical connection being solicited in traction in order to provide the maintaining under constraint of the ends of the joinery profiles of the intermediate portion of the frame against the corresponding ends of the joinery profiles, arranged on either side of the intermediate portion, belonging to the mullions or cross-members.

A frame assembly with strengthened corners is described. The frame assembly includes internal corner sets that squeeze or pull mitered or angled edges of frame sections together. The corner sets fit into openings at corners between adjacent frame sections. The frame assembly includes corner braces that snap lock over a corner between adjacent frame sections. The corner braces fit over exterior surfaces of the frame sections forming the frame assembly. The corner brace snaps into grooves in the exterior surfaces of the frame sections. The frame assembly includes a corner member that engages to an outer flange of joining frame sections. The corner member spans the corner between the joining frame sections.

A screen includes a frame and a panel coupled to the frame. The frame includes a first frame member having a first longitudinal axis, a first opening extending therethrough along the first longitudinal axis, and an aperture extending along an axis that intersects the first longitudinal axis, a second frame member having a second longitudinal axis and a second opening extending therethrough along the second longitudinal axis, and a connecting member coupled between the first frame member and the second frame member. The connecting member has a first portion that is received within the first opening and having a plate movable via a fastener to clamp the plate against the first frame member. The first fastener is accessible through the aperture. The connecting member also includes a second portion that is received in the second opening.

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.

A connection assembly 10 usable for interconnecting two elongate frame members 12 which each include a channel 14. An elongate link member 22 is locatable in the channels 14 of the adjacent members 12 and extending therebetween. A respective connection assembly 20 is locatable in each of the channels 14 to engage against the link member 22 and retain same in the respective channel 14. Each connection assembly 20 is selectively movable between an engaged and a disengaged condition to respectively connect the two frame members 12, or permit the frame members 12 to be pulled apart.
