DESCRIPTION:
BRIEF SUMMARY
This invention is concerned with window and door assemblies. Conventional window assemblies as used for many years comprise a wooden or metal frame incorporated within a window aperture. Glazing is subsequently fitted into the frame and held in position by putty or the like.
The installation of such window frames is time consuming and requires skilled labour.
Conventional wooden doors are supported upon hinges which are directly attached to the frame work forming a door aperture and supporting the door in use. Heavy duty doors are costly and difficult to install and again generally require skilled labour.
It is from a consideration of existing window and door assemblies which has lead to the development of the present invention.
According to a first aspect of this invention there is provided a door or window assembly comprising a rigid first frame defining an opening, and a second frame adapted to be fitted into and close off the opening in the first frame, the first frame being at least partly or wholly hollow and having a surface part with an opening leading into a channel section partly defined by side walls of the said first frame, the second frame including retaining means of which a part can enter said channel section through said opening and thereafter securely engage the first frame to prevent the second frame from being withdrawn from the first frame.
According to a second aspect of this invention, a method of constructing a window or door assembly is provided in which a first frame is incorporated within a building structure during construction thereof, the second frame, with or without attached third frame, as defined above including retaining means is offered up to the first frame whereupon the retaining means are actuated to securely affix the second frame to the first frame.
The second frame can include a glazing unit or a door structure, preferably through the intermediary of a third frame. In this regard the first frame is most conveniently incorporated within the building structure during its erection. A ready-made door or glazing unit which is essentially complete can readily be applied to the first frame and subsequently secured thereto in a convenient manner which does not require skilled labour.
In the case of a door assembly such third frame is conveniently pivotally connected to the second frame. In the case of a window assembly the second frame may be pre-glazed and again easily inserted into the opening defined by the first frame whereafter the retaining means can be actuated to rigidly hold the second frame in position upon the first frame.
In a preferred construction retaining means comprises a bolt and anchor assembly. The anchor most conveniently is capable of resting within a recessed part of the second frame to be level with or flush with that surface of the second frame which is intended to be located adjacent that surface of the first frame which includes said opening. Accordingly the anchor may then be inserted through the opening, into the channel section and then caused to engage the side walls. Such an arrangement will become more apparent from the description of a preferred embodiment.
The first frame is preferably constructed from channel section having a surface part adapted to engage that surface part of a second frame which includes the recess, and which surface part is generally parallel with a base part adapted to engage the aperture within the building structure. The said channel frame can be securely mounted to the building structure within the appropriate aperture by means of ties and the like. It is convenient for the first frame to be substantially completely hollow and include generally parallel and upright side walls and/or depending lips which can engage a part of the retaining means.
In order that the invention may be more readily understood, it will be now described by way of example only with reference to the accompanying drawings depicting a preferred embodiment and in which:
FIG. 1 is a vertical section through a second frame forming part of the asse
