3 Claims. (Cl. 20-56.4)

The present invention relates to a sash construction and has for its primary object the provision of a sash construction particularly suited for mounting and retaining a pane of glass in a window opening.

Another object of the present invention is the provision of a new and improved sash construction for window openings in doors and the like and including primary and secondary glazing frames which can readily be inserted into an opening in the door and held in assembled relation therein.

A further object of the present invention isthe provision of a new and improved sash construction for window openings in doors or the like and including opposed primary and secondary frames insertable into the opening in the door from opposite sides of the door and which frames are constructed and arranged to provide a full floating mounting for a pane of glass and which are held in assembled relation by easily locked securing means, which securing means is hidden inside of the frames so that it is not visible.

In brief, the sash construction includes primary and secondary glazing frames insertable into a window opening in a door or the like. The primary glazing frame is insertable into the opening from one side of the door and the secondary glazing frame from the other side of the door. Each of the frames comprises a plurality of glazing strips connected at their ends to form a frame corresponding to the opening. Each of the primary strips includes a horizontal arm seated on the door structure at the edge of the opening and having a length slightly less than the thickness of the door, a vertical portion including a dependent flange abutted against one side of the door and an upwardly extending portion, and a portion above and parallel to the arm, the inner end of which extends to adjacent one side of a window pane to be held between the two frames. The secondary frame comprises a plurality of secondary glazing strips each of which in cludes a horizontal arm slidably seating on the horizontal arm of a primary glazing strip, a vertical portion including a dependent flange abutted against the other side of the door and an upwardly extending portion, and a portion above and parallel to the arm, the inner end of which extends to adjacent the other side of the window pane. The two frames are assembled relative to each other and the window pane by locking means disposed within the frames. The locking means includes a plurality of spring clips secured to the horizontal arms of the primary glazing strips and terminating in latching means associated with the latching means at the ends of the spring clips or other latching means on the horizontal arms of the secondary glazing strips. The locking means are so arranged that the secondaryglazing strip can be locked to the first simply by sliding movement thereof toward the door. A full floating mounting of the glass is provided by utilizing resilient sealing means between the dependent flanges on the primary and secondary frames and the adjacent surfaces of the door, and between the pane of glass and. the

adjacent ends of the upper portions or arms of the glazing strips.

Other objects and advantages of the present invention will become apparent from the ensuing description of an illustrative embodiment thereof, in the course of which reference is had to the accompanying drawing, in which:

Fig. l'is a front elevational view of a door including the sash construction of the present invention;

Fig. 2 is an enlarged fragmentary cross sectional view taken along the line 22 of Fig. 1; v

Fig. 3 is a similar view taken along the line 3-3 of Fig. 1;

Fig. 4 is a fragmentary and partly broken away front elevational view of the primary glazing frame apart from the door;

Pig. 5 is a fragmentary exploded cross sectional view illustrating a pane of glass supported adjacent theprimary glazing frame with the secondary frame ready to be installed (the door being omitted); and

Fig. 6 is an enlarged perspective view of one of the spring clips secured to the primary glazing member.

Referring now to the drawing and first to Fig. l, the sash construction of the present invention is indicated as a whole by the reference character 10. It will be noted that there are three such constructions mounted upon a door indicated as a whole by reference character 12.

Referring now briefly to Figs. 2 and 3 the door is shown as including a first wall surface 14 which may be the outer wall and a second and inner wall surface 16. These wall surfaces'are at the outer sides as of metallic panel members 18 and 210. The walls are separated by core structure which may include, for example, the panels 22 of wood or Masonite or the like which are, in turn, secured to opposite sides of a cellular honeycomb core structure indicated by the reference character 24. The door is provided with one or more suitable window openings, indicated by the reference character 26 in Figs. 2 and 3, in which the sash construction of the present invention is mounted.

The sash construction of the invention includes a primary glazing frame 30 and a secondary glazing frame 32, the two frames being in what might be considered opposed relation and securing between them a panel such as the glass panel 34. The frames provide a full floating mounting for the window pane and they are secured in assembled relation relative to each other and the door by a concealed securing means indicated generally by the reference charactor 36 and which will be described hereinafter.

The primary frame is constructed of four primary glazing strips 40 which will be described with particular reference to Figs. 2, 3 and 4. The glazing strips are connected to each other at their ends by generally right angled corner clips '42 which are secured to adjacent strips by four screws 44, see Fig. 3.

Each of the primary glazing strips includes a generally horizontal arm 46 seated on the edge of the opening 26 extending substantially but not quite across the full width of the door. The primary glazing strips include also a vertical portion 48 having a dependent flange 50 abutted against the outer surface 14 of the door. The lower portion of the flange is inturned as indicated by'the reference character 52 to provide a small space for the reception of a resilient glazing compound 54 spacing the strip from the door wall whereby there is provided a floating mounting of the primary frame structure relative to the door. The primary glazingstrip includes also a second arm portion 56 located above and parallel to the arm 46. The upper arm 56 extends vto adjacent the glass pane and terminates in a dependent channel structure 58 for the reception of the resilient glazing'compound -60 abutting against the glass pane .34 whereby thereis afforded a full floating connection between the pane of glass and the primary strip.

The secondary glazing frame 32 is constructed of four secondary glazing strips 62 which are connected together to form a frame by the corner clips 64 (only one of which is shown, Fig. 3) which are secured by the screws 66 to adjacent ends of two glazing strips. The secondary glazing strips are similar to the primary glazing strips but are arranged to be in opposed relation thereto and to seat upon the horizontal arms 46 of the primary strips. Accordingly, each of the secondary glazing strips is provided with a horizontal arm portion 68 slidably seated on the arms 46 of the primary strips. It includes a vertical portion '76 having a dependent flange 72 with an inturncd lip 74 at its lower end to provide a space for the glazing compound 76 providing afloating mounting for the secondary glazing strip. The secondary glazing strip includes also an upper horizontal arm 78 extending to adjacent the glass panel and terminating in the dependent channel structure fill for the reception of resilient glazing compound fill which abuts against the glass.

The primary and secondary glazing frames are held in assembled relation by the securing means 36 which, as noted heretofore, is mounted within the frame structure. The securing means includes a plurality of glazing clips 82 of which there may be several for each glazing strip. The glazing clips include a horizontal securing portion 84 apertured for the passage of securing screws 85 therethrongh and which are threaded into an opening in the lateral arms 46 of the primary glazing strips. Each glazing clip includes an upwardly inclined portion 86 and a reversely downwardly bent locking portion 88. The secondary glazing strips are each provided with a locking projection 9ft engageable under the locking projections 88 on the clips, as best illustrated in Fig. 2. The locking projections 90 are preferably coextensive in length with the secondary glazing strips.

From the foregoing detailed description of the invention it may be noted that the sash construction of the present invention can be constructed and installed readily and economically. Each of the frames is constructed as a complete unit prior to assembly, this requiring simply the connection of the four glazing strips to form a frame. In addition, the resilient glazing compounds 54, 69 and '76 may be applied prior to assembly. Thereafter, the primary glazing frame is inserted into the opening from one side of the door and the glazing clips are attached thereto. The window pane is then inserted into place and supported on the pads 94, after which the secondary glazing frame is inserted into place so that it abuts against the window pane and is locked in place by the securing means 36.

While the present invention has been described in connection with the details of a particular embodiment thereof, it should be understood that these details are not intended to be limitative of the invention except insofar as set forth in the accompanying claims.
