The invention is a method, an apparatus and a kit of parts for assembling a universal frame with at least two jambs, a lintel and a sill. The resulting frame is suitable for any size of opening and any size of door, with the option to include single doors or double doors as well as side screens and/or side lights. The frame is typically assembled by cutting the jambs (and optionally the sill and/or lintel) to a selected size, attaching keys to each end of each jamb and inserting the keys into keying channels in the sill and lintel.

A window assembly includes a polymer (e.g., polyvinyl chloride, vinyl) window frame made and a glass unit carried by the window frame. The window frame includes a pair of jambs and an astragal that extends between and interconnects the pair of jambs. The jambs have a channel or slot sized to receive therethrough one or more end walls of the astragal so that at least a portion of said one or more end walls extend into a hollow cavity in the jambs that is in fluid communication with one or more weep holes of the window assembly. The one or more end walls of the astragal and channel or slot of the jambs define a flow path configured to channel water from the astragal, through the channel or slot in the jambs and into the hollow cavity such that said water exits the hollow cavity and the window assembly via the one or more weep holes.

The present invention provides a door frame comprising of two piece units and the method of installment to provide connection between the casing and the frame with a self-alignment system. This is done by a tongue and groove connection and plurality of prefabricated dowels that are specially formed to engage the grooves provided in the frame through the entire attachment area of the frame units together. The door frame units are being assembled and secured together by providing a solid reinforced assembly. In the door frame system of the present invention a strong square joint can be produced by inserting dowels at critical joints which is significantly stronger fastening mechanism than other fastening means such as nails, staples, etc. Low expansion reinforced foam fills the cavities of the frame and creates a solid bond between door system and casing.

A frame assembly for installation into a door or window casing is provided. The casing has a top and two side studs. The assembly includes a head jamb, a pair of side jambs, and a pair of connecting mechanism. The head jamb is removably securable to the top stud. Each side jamb is removably securable to a respective one of the two side studs. Each connecting mechanism for connecting a respective one of the side jambs with a corresponding end of the head jamb includes a first component and a second component. The first component is provided on the head jamb, and the second component is provided on the side jambs. The first and second components are removably engageable, and allow the frame assembly to be installed and uninstalled from the door or window casing. A method for removably installing the frame assembly is also provided.

A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.

An apparatus for an architectural opening may include a plurality of panels. At least one of the plurality of panels may include a frame including a plurality of first frame members and a plurality of second frame members sealed together at respective interfaces to define at least one opening. The interfaces may be defined by ends of the first frame members positioned at least partially within respective apertures defined in the second frame members. Each frame member may include an internal cavity, with the apertures fluidically connecting the internal cavities of the frame members. An inset panel may be secured within the at least one opening. One or more hinges may pivotably connect a first panel of the plurality of panels to a second panel of the plurality of panels. The apparatus may be a garage door, an entry door, a window, or a storefront.

A method of connecting hollow elongate members 12 which may be window frame members. The method comprising locating a plastics material insert 16 extending outwardly for a short distance from each hollow member 12, heating the inserts, and bringing the hollow members together such that the heated inserts 16 fuse together to connect the hollow members 12.
