An improved composite structural member comprising a complex profile structural member, made of a composite comprising a polypropylene polymer and a wood fiber. The material is useful in conventional construction applications. The complex profile, in the form of an extruded thermoplastic composite member can be used in residential and commercial structures as described. Preferably, the structural member is used in the manufacture of the fenestration components such as windows and doors. Such linear members are designed with specifically configured cross-sectional shapes to form structural elements in the fenestration units. Structural elements must possess sufficient strength, thermal stability and weatherability to permit the manufacture of a structurally sound window unit that can be easily installed into a rough opening but can maintain its attractive appearance and structural integrity over the life of the window unit often twenty years or more. The structural member comprises a hollow complex cross-section with at least one structural web or one fastener web formed within the component. The exterior of the extruded component has a visible capstock layer and is shaped and adapted for installation in rough openings. The exterior also contains shape and components capable of supporting the elements of the fenestration unit such as a window, sash or movable door unit. The improved polypropylene structural members have unique advantages and can be assembled in thermoplastic weld processes.

A sliding latch and locking mechanism, for windows and doors, whereby the latching mechanism provides a means for discrete position retention of a sliding window or door and provides an increased measure of security. The latching system combines four modes of operation i.e. lock, close only, raise (free sliding), and tilt to provide angular pivoting of window sash, that allow three levels of security, i.e. fully locked, close only with discrete positions maintained, and raise or lower without discrete positions maintained (free sliding). The latching system security levels are accomplished by means of a selector knob positioned to the desired mode of operation. Also, a mechanism is integrated to provide interlocking in the fully closed position with the upper or adjacent window or door sash.

A combination of profiles for forming slider and double hung sash windows or patio doors includes a common outer profile and two different inner profiles so that one inner profile can be used to form the double hung and the other to form the slider. This allows the slider top inner to be cut away to form a floating section resting on the top of the sash. This allows the drain holes to be formed separately in the inner and the outer to be longitudinally offset to prevent direct air penetration. The sash frame is formed with a removable glass stop on one side which snaps into engagement at right angles to the glass surface of the sealed unit to allow formation of a tri-pane with 0.5 inch spacing and to allow the use of two strips of adhesive one on each side of the sealed unit with no need for drainage.

This fenestration locking system for a swinging sash or door is characterized by the use of a linear member running continuously from an actuating assembly to a locking pin assembly. The linear member can be a flexible linear member, allowing it to convey motion to the locking pin assembly around corners. The locking pin assembly has a moveable locking pin with an actuator and an extension that can engage a keeper. The linear member has multiple actuator engagement sites along its length where the actuator of the locking pin can engage the linear member. The linear member can then be used to move the locking pin with respect to the locking pin assembly so that the extension can engage or disengage a keeper. The locking pin assembly can be mounted on a fenestration frame and the keeper opposingly mounted on a window or door mounted in the fenestration frame. Alternately, the keeper can be incorporated into the fenestration frame and the locking pin assembly opposingly mounted on the window or door mounted in the fenestration frame.

A retractable badge reel with a billboard designed to display a logo, such that unadorned badge reels can be manufactured separately from the billboards that contain the logos. The billboard is optionally removable, allowing the logo being displayed to be changed without having to produce new retractable badge reels in their entirety. In another embodiment, a billboard designed to display a logo is adapted to be installed over the face of an existing retractable badge reel, such that the logo on the existing unit is hidden and the new logo on the billboard is instead displayed. A casement comprising the billboard and a back housing member have a mating portion that mates with a bob mating portion of a bob attached to the exterior end of the retractable cord to prevent the bob from shifting or twisting when the cord is in the retracted position.

A laminated glass retention system for securing a laminated glass subassembly within a window sash or frame member or door panel or similar component includes a retention member applied to the laminated glass subassembly. The retention member generally can include a leg portion that engages of the laminated glass subassembly, and can further include a base portion that is coupled to the frame member in which the laminated glass subassembly is seated. The retention member helps retain the insulating glass subassembly within its frame member when subjected to high winds and wind-borne debris.

A pivot hinge for roof windows with a sash pivoting around the axis located between the upper and the lower member of a window, has a balancing system, which ensures the state of equilibrium of a window sash when its centre of gravity is located outside the sash rotating axis and the friction spring of the hinge is unable to hold the sash pivoted in each its position. At the same time the window fittings, its assembly, installation in a roof and its appearance remain unchanged. Also the method of separating of both hinge parts (taking a sash out of a window frame) remains unchanged.

A sash lock mechanism includes a handle, a housing adapted to be supported by a sash window assembly, the housing having an opening receiving the handle therethrough, and a rotor coupled to the handle. The rotor is moveable between at least a locked position and an unlocked position by movement of the handle. The sash lock mechanism also includes a locking mechanism that contains a pivotable member pivotably connected to the housing. The pivotable member is pivotable between a first position and a second position. When the rotor is in the locked position and the pivotable member is in the first position, the pivotable member confronts the rotor to prevent movement of the rotor to the unlocked position. When the pivotable member is in the second position, the pivotable member does not prevent movement of the rotor.
