(Cl. 'l2-99) 7 Claims.

This invention relates to composite windows of a decorative or display nature.

Many types of decorative or display windows and glass panels have heretofore been proposed. One such type is the conventional leaded glass window which consists or" transparent or translucent pieces of glass held together in a series of lead channels. Such a unit is usually supported in a wood or metal frame which is built into the associated building structure. This construction is expensive and employs a substantial amount of metal. The lead channels projecting beyond the face of the glass tend to hold dirt and make cleaning a difficult operation. Moreover, such an assembly is inefcient in the conservation of heat since the metal parts employed provide a good heat transfer medium.

An object of the present invention is to provide a composite window having a smooth, continuous, easily maintained glass surface. Another object is to provide such a window wherein the decorative or display element constitutes a thermal barrier. Still another object is to p-rovide a window unit comprising a composite assembly of concrete, plastic composition, and glass, which may be easily installed in masonry walls by artisans having ordinary skill, and which eliminates the use of metals and other difiicultly available construction materials.

IThe manner of attaining these and other ob jects will become apparent from the following description of the invention, with particular reference to the accompanying drawing, in which:

Figure l is a side elevation of a window constructed in accordance with the invention,

Figure 2 is a sectional end elevation of the window,

Figure 3 is an enlarged sectional end elevation of a portion of the window,

Figure 4 is a side elevation of a slightly varied form of window, and

Figure 5 is an enlarged sectional, partial, end elevation of a modified form of window structure.

Referring to the drawing, the window shown comprises a pair of substantially similar concrete frames l and 2, which may be readily cast or molded in a simple trough mold. The inner or meeting faces 3 and of the frames are substantially identical. A decorative or display panel or partition 5 of a suitable synthetic plastic composition, such as polystyrene, is interposed between the frames l and 2. The panel 5 has a continuous marginal portion 6 which extends throughout the area of meeting faces 3 and 4 and projects somewhat beyond the inner corner portions of the frames to provide a flange or strip l for engagement by the peripheral portions of a pair of glass sheets B, the main portion of the panel being sandwiched between such glass sheets. During assembly, the opposite side surfaces of the panel portion t are softened as by use of a suitable solvent and then pressed between the faces 3 and l to form on hardening a sealing lm 9 on each side of portion and bonding the latter to the faces 3 and Il.

The edges of each glass sheet are seated in a glazing strip lll, which may comprise a molded rubber or like resilient strip or any suitable glazing compound of conventional nature, which will adequately seal the glass sheets in the assembly. Preferably, the inner corners of each frame l and 2 are recessed at Il to receive the glazing strip, the latter being wedged into the recess and thereby exerting sealing pressure on the edges of the glass sheet.

The outer corners of each frame l and 2 adjacent the periphery of panel 5 are preferably recessed as indicated at l2 to receive a waterproof sealing compound or strip I3, which engages the peripheral edge of panel 5.

The decorative or display motif incorporated in panel 5 may vary as desired. As shown in Figures 1 and y2, it may comprise a plurality of cut-out openings forming a series of transparent areas lll and translucent or opaque bars I5. As shown in Figure fl, it may comprise portions i@ of decorative outline which may be in connected or disconnected relation to each other. Alternatively, as illustrated in Fig. 5, the motif may be formed by pockets or depressions Il of varying depth and outline in the. plastic panel. The pockets il', normally filled with air, cause a refraction of light not possible Where the glass and panel are in intimate contact. The differences in refraction of the transmitted light proj vide a plurality of areas of contrasting shades, which enhances the appearance of the panel. Portions of the panel may be formed in contrasting colors.

The concrete frames each has a generally rectangular section which is easily formed and .readily disengaged from a rigid mold. As shown,

I3, and the outer periphery of the glass sheets 8 being in sealing engagement with the resilient glazing strips l0. The extension of the panel for the purpose of providing the ledge 'l against which one side of each glass sheet bears and the provision of the recesses Il to receive the resilient glazing strips is advantageous.

The fact that the glass sheet on either side of the panel may be removed and replaced independently, greatly simplifies repairs and reduces cost of maintenance. i

Ii desired, frame 2 may be recessed as indicated at i9 to receive a sill 20 of a Window supporting structure 2|.

What is claimed is:

1. A composite window structure comprising a pair of separate masonry frames arranged in laterally alined relation, a plastic composition panel having a continuous marginal portion rigidly sandwiched between said frames and supported thereby, said panel having a continuous ledge portion projecting inwardly beyond said frames, a resilient glazing strip seated on each of said frames in juxtaposed relation to said ledge portion, and a pair of glass sheets, the edge oi each sheet being seated in a respective one or" said strips and each having its peripheral portion engaging said ledge portion, said panel being thereby also sandwiched between said glass sheets.

2. A composite window structure as defined in claim l., said panel having cut-out openings therein forming a display motif.

3. A composite window structure as defined in claim l, said panel having in one surface thereof depressions forming a display motif.

A composite window structure as defined in claim 1, said panel having in one surface thereof depressions of varying outline and depth to form a display motif therein.

5. A composite Window structure comprising a pair of separate masonry frames arranged in laterally alined relation, said frames having substantially identical faces in spaced, facing relation to each other, a plastic composition panel having a continuous marginal portion rigidly sandwiched between said meeting faces and supported thereby, said panel having a continuous ledge portion extending inwardly beyond the inner corners of said frames, a pair of glass sheets each having its peripheral portion engaging said ledge portion, said panel being thereby also sandwiched between said glass sheets, and a resilient glazing strip seated on each of said frames in juxtaposed relation to said ledge portion, the edge of each glass sheet being seated on a respective one of said strips.

6. A window structure as defined in claim 5 each said fraine having a recess therein extending continuously around the inner corner thereof, said glazing strip being seated in said recess.

'7. A window structure as defined in claim 5, each said frame having a recess therein extending continuously around an outer corner thereof adjacent the periphery of said panel, and a sealing strip seated in said recess and engaging the periphery of said panel.
