Description
FIELD OF THE INVENTION
[0001] The present invention relates to cassette framing systems, and more particularly to cassette framing systems using hinge assembly units. These hinge assembly units employ narrow joint profiles which provide aesthetics benefits. They also enable the ease of on the field installations. A cassette framing system includes at least one cassette comprising a frame and infill material, and at least one hinge assembly unit, which allows for loading the top of a cassette frame onto a structural mullion located within the cassette framing system.
DESCRIPTION OF THE PRIOR ART
[0002] The present invention refers to a cassette framing system consisting of one or more cassettes framed within a cassette framing system. Cassette framing systems are well known within the art. Such cassette framing systems have however, employed installation techniques different from those employed by the present invention. Such prior art systems do not provide for ease of use in the field and/or provide for bulkier joint profiles.
[0003] The prior art includes cassette framing systems using project-in fastening systems for loading a cassette within a cassette framing system. The project-in fastening systems required that a cassette be held in place in its target location by one or more installers, while the cassettes were fastened in the field. See FIG. 14. While project-in fastener systems involve smaller joint profiles, additional man hours and skilled labor are required to stabilize and hold a cassette in place while the cassette is fastened to the cassette frame. As the cassettes can have significant weight in the hundreds or thousands of pounds, holding the cassettes in place posed physical dangers to the installers, if the cassettes were to slip out of or within the cassette framing system. The cassettes may also be large in size, rendering the handling of the cassettes unwieldy and cumbersome.
[0004] Other prior art includes cassette framing systems using hook-on fastening systems for loading a cassette within a cassette framing system. Such hook-on systems provide some convenience and ease in on the field installations but required the use of larger joint profiles. See FIG. 15. The hook on systems have exterior horizontal dimensions which must be sufficiently sized to permit a cassette with an attached hook to be raised, angled, and mounted onto a structural mullion, within those horizontal dimensions. These hook on systems therefore required the use of additional space around the cassette frame, which resulted in larger joint profiles. These larger joint profiles detract from the aesthetics of the cassette framing systems, as they created a bulkier appearance.
SUMMARY OF THE INVENTION
[0005] It is an object of the present invention to create a cassette framing system of the aforementioned kind that will remedy the drawbacks of the known solutions. The cassette framing system according to the present invention substantially departs from conventional concepts and designs in the prior art. In so doing, it provides an apparatus which neither uses prior art devices such as project-in fasteners or hook-on fasteners. An aspect of the present invention is to provide a cassette framing system which provides for convenient on the field installation of cassettes within the framing system, while providing an aesthetically favorable joint profile.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] In view of the foregoing disadvantage inherent in the prior art, the present invention provides the convenience of on the field installation, while employing a narrow joint profile in the form of a hinge.
[0023] In an embodiment of the present invention, the cassette framing system is designed such that the top of the cassette may be aligned onto an anchor, which results in the stabilization and alignment of the cassette while the cassette is lowered or moved into place.
[0024] With reference now to the drawings, and in particular to FIGS. 1 through 13 thereof, a new cassette framing system embodying the principles and concepts of the present invention will now be described.
[0025] The present invention is adapted for use within an opening wherein structural mullions may be anchored into an opening of a cassette framing system. FIG. 1 shows a potential configuration for the placement of the structural mullions [1] against anchor points [2] located on an upper periphery edge [3] and on a lower periphery edge [4] of a cassette framing system [5]. The vertical mullions [6] are attached to anchor points [2] located on an upper periphery edge [3] and on a lower periphery edge [4] within a cassette framing system [5]. Note FIG. 2. Horizontal mullions [7] are attached to the vertical mullions [6] within the cassette framing system. Note FIG. 3.
[0026] One or more cassettes [15] may then be mounted onto the horizontal and vertical mullions [6, 7], into the open space or spaces [8] created by the placement of the mullions onto the cassette framing system. Note FIGS. 3, 4, 5. A close-up rendering of the mullions anchored onto the cassette framing system depicts the open spaces [8] created by the placement of such mullions. Note FIG. 6. A cassette is mounted onto the structural mullions such that the open space, created by the placement of the structural mullions, is filled when the cassette is in its mounted and resting position. FIGS. 6, 7, 8.
[0027] Hinge assembly units are used to mount the cassettes within the open space. A hinge assembly unit is comprised of a cassette receiver [9] located on a structural mullion [1], and the upper rim [10] of a cassette frame [11]. See FIGS. 9, 10. The upper rim [10] of the cassette frame [11] connects with a cassette receiver [9] which contains a groove [12] for receiving the hinge frame. FIG. 9 shows a partial cross section view of a cassette receiver attached to a horizontal structural mullion. FIG. 10 shows a partial cross section view of the upper rim [10] of the cassette frame with a mounting arm [14] located on the cassette frame, which fits into the groove [12] in the cassette receiver [9]. Infill material [13], such as glass, is attached to the cassette frame [11]. Options for infill materials include, but are not limited to plastic, metal, stone, concrete, and cement. A variety of types of infill materials may be used.
[0028] The upper rim [10] of the cassette frame [11] is mounted onto the structural mullion [1] by positioning and resting the mounting arm [14] of the cassette frame [11] within the groove [12] of the cassette receiver [9]. FIGS. 10, 11. The cassette frame is then affixed to the structural mullion and to the cassette framing system.
[0029] The cassette frame may be affixed to the structural mullion and to one or more neighboring mullions with screws or other mechanical fasteners. The use of a chemical adhesive is another option for affixing the cassette frame to one or more structural mullions. Heat may also be used to solder, weld, braze, or otherwise fasten the cassette to one or more structural mullions. Another option is to have the cassette frame extend down the sides of the cassette. Yet another option is to have the cassette frame extend to the bottom edge [16] of the cassette. FIG. 12 Thus, the cassette may be affixed with screws, mechanical fasteners, soldered, welded, brazed or otherwise affixed along the sides or along the bottom edge of the cassette frame. Mechanical fasteners, heat, and chemical adhesives may similarly be used to affix the horizontal mullions to the vertical mullions. FIGS. 11, 12 shows a partial cross section view of a second cassette [15] being mounted onto the cassette framing system, and into the open space created by neighboring structural mullions. As set in this paragraph, one embodiment of the invention is to add a bottom edge to the second cassette's frame and to mount the bottom edge to the frame of the cassette located directly below the subject cassette. The bottom edge may be affixed to the top edge of a second cassette's frame for additional support and stability. FIG. 13. Alternatively, the bottom edge may be affixed directly to a horizontal mullion. Other embodiments may eliminate the bottom edge of a cassette.
[0030] While the included drawings depict a cassette frame with an upper rim and a mounting arm which spans the top edge of the cassette, one skilled in the art would appreciate that the mounting arm may be reduced in width. The width of the mounting arm may be reduced considerably such that the mounting arm resembles a clasp, which catches onto the groove located on the cassette receiver, during the mounting process. One skilled in the art would also appreciate that additional materials such as gaskets, thermal breaks, structural silicone, and glazing tape may be used to increase the structural integrity of the cassette framing system, to prevent the conduction of energy through the cassettes, to improve the sealing of edges surrounding the edges of the cassette frame, infill material and mullions, and to prevent leakages of air, water, and other substances.
[0031] In other embodiments of the invention, the placement of the structural mullions within the opening may vary and result in different configurations of the mullions. In another embodiment of the invention, the cassette framing system may consist of a single cassette, or it may consist of more than one cassette.
[0032] The present invention is not limited to the embodiments described herein. One embodiment would be the installation of glass window cassettes within a cassette framing system. But the present invention is not limited to this embodiment. As noted herein, other infill materials such as steel may be used, for various other applications. Those skilled in the art will appreciate that the invention, upon which this disclosure is based may readily be used as a basis for designing other structures, methods, and system for carrying out the purposes of the present invention.
[0033] With respect to the description herein, optimal dimensional relationships for the parts of the invention, including variations in size, materials, shape, form, function, manner of operation, assembly and use are deemed readily apparent and obvious to one skilled in the art. All equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
[0034] The foregoing is considered as illustrative only as to the principles of the invention. Numerous modifications and changes will readily occur to those skilled in the art and the foregoing is not intended to limit the invention to the exact construction and operation shown and described. Accordingly, all suitable modifications and equivalents are resorted to fall within the scope of the invention.
