Abstract: An astragal formed as a part of an extruded door sash is described. The astragal is formed integral with the door sash as an elongated forwardly projecting member constituting an astragal base. An elongated detachable cap is releasably secured to the base member and extends forwardly thereof. A core member is disposed internally of the door sash and projects along the outer end edge portion of the sash and at least in part within the astragal. The astragal base member and the door sash form a unitary member.

Abstract: A modular anti-warping door panel for use in the construction of a door or door panels. The door panel comprises a rigid reinforcing frame constructed of material resistant to warping. The reinforcing frame is defined by two spaced apart elongated rigid members and one or more transverse spaced members. The reinforcing frame is retained in an elongated butte stile and a lock stile and a top and bottom rail. The stiles and rails are formed as hollow members of rectangular cross-section forming a peripheral panel frame. The two elongated rigid members are retained along an inner peripheral channel of the rectangular door frame. Panels are retained in an opening defined by the inner peripheral channel. A rigid post is secured in the butte and lock stiles along an outer edge portion thereof and concealed within the hollow stiles.

Abstract: A latch mechanism for securement to an edge portion of a closure element, and more particularly, but not exclusively, a sliding door. The door latch mechanism has a housing with a slide member having keeper engaging hook members to engage a keeper secured to a door jamb for locking and unlocking the door within a door frame. The slide member is guided along a straight axis and is connected to a finger engaging knob to displace it along that axis to lock and unlock the mechanism with the keeper. The slide member has one or two elongated through bores extending co-extensively with the straight axis and a load transfer pin-like member extends through the bores and connected on opposed sides to transfer lateral loads applied to the slide member to the door latch mechanism housing and door stile.

Abstract: A latch assembly for securement to a common side of a sliding pane and frame to lock the sliding pane to the frame. Particularly, but not exclusively, the latch assembly is secured to a sliding door and the frame of that door. The assembly comprises a handle member having a handle housing for receiving a lock assembly having a locking element actuable therein. The housing has a slotted portion for receiving a securement flange provided on a stile on the common side of the sliding pane for securement to the flange. A keeper member is secured to the frame in alignment with the locking element to receive same therein when the lock assembly is positioned thereagainst. The handle member and keeper member are both secured to the stile and frame respectively, by fasteners which extend substantially parallel to the plane of the sliding plane.
