The glass is fractured and the unit manipulated into a desired shape. Once the adhesion has set the vinyl is removed.
Description
GLASS BENDING PROCESS
The present invention relates to a process for bending glass and more particularly, the present invention relates to a process for bending glass in the absence of applied heat or ancillary apparatus for effecting the bending.
Glass bending techniques have been previously proposed in the art. Generally speaking, the known techniques involve sizeable devices having press rollers and arrangements for applying heat. The heat is required to render the glass more malleable and thus bendable without fracture. Force is applied by rollers or other devices and sustained during cooling of the glass in order to "set" the desired shape.
Although useful, this technique typically involves a large area to accommodate the apparatus, skilled workers to operate the apparatus and has inherent limitations regarding the extent the glass can be bent prior to breakage.
Representative of the art is United States Patent No. 5,713,976, issued to Kuster et al., February 3, 1998. The reference teaches a process for bending glass sheets where the sheets are in pairs and are subjected to a preliminary stress on a concave bending device.
The profile of the device corresponds to the desired final profile of the glass sheets. The bending is also assisted by suction. The apparatus used to effect this bending is fairly complicated and involves multiple stages in order to effect the desired result.
Funk in United States Patent No. 6,009,726, issued January 4, 2000, teaches a further variation of glass bending methodology and an apparatus to effect the process. In this process, the glass being bent comprises an outer glass pane and an inner glass pane of laminated safety glass. The method is effected by a press bending device having a bending phase, a discharge phase and a means for conveying the glass from operational base to the other. The bending is effected by a combination of stress and heat where the unit to be bent is heated to a bending temperature. Once again, this method involves an apparatus that is fairly substantial and further, requires the use of heat in order to effect the bending.
In United States Patent No. 5,882,370, issued to Gamer et al., March 16, 1999, employs a molding apparatus which effectively applies weight to the unit to be bent and further incorporates the application of heat to raise the temperature of the unit sufficiently to effect bending. A cooling phase is also required to "set" the bend in the glass.

A cooling phase is also required to "set" the bend in the glass.
From a review of the art, it is evident that there is no provision for any process where heat is not required to effect the bending or any significant apparatus for the application of a preformed weight, etc.
It would be desirable if there were a method for bending glass or otherwise reconfiguring the glass from its initial planar state to a finer state by bending, twisting or otherwise manipulating, which method did not require the use of expensive apparatus, preformed molds or the application of heat. The present invention addresses all of these needs.
A generic object of the present invention is to provide a process for bending glass which is not encumbered by the use of high temperatures or expensive apparatus to effect bends in glass.
One aspect of one embodiment of the present invention is to provide a process for bending glass, comprising:
providing a first sheet of tempered glass and a second sheet of tempered glass;
providing an adhesive capable of bonding with the tempered glass;
applying the adhesive to at least one sheet;
positioning the first sheet of tempered glass in overlying relation with the second sheet of tempered glass forming a joined unit with adhesive there between;
providing flexible holding means for holding the joined unit during fracture of the glass;
fracturing the glass; and bending the joined unit within the holding means into a desired shape.
The process in accordance with the present invention is distinguished from, for example, safety glass preparation in that there is a requirement in the latter for a layer of support in the form of a plastic, inter alia, sheet. The present invention employs a settable adhesive between the sheets. Once the sheets are fractured locally or entirely, the adhesive penetrates interstitially of the individual fractured segments and between the sheets to result in innumerable bonds thus providing a consolidated unit. The provision of a holder or temporary containment member in the form of, for example, a flexible sheet imparts integrity to the formed structure while the adhesive sets. This is easily removed once the adhesive has set.

providing flexible material for temporary overlying contact with each sheet of the unit during fracture of the glass;
fracturing the glass;
bending the joined unit into a desired shape; and removing the flexible material upon setting of the adhesive.
Evidently, the process can produce a host of articles including as examples furniture, works of art, building materials, signage, among a host of others.
Another aspect of one embodiment of the present invention is to provide a contoured glass article, comprising:
a first contoured layer of shattered tempered glass;
a second contoured layer of shattered tempered glass in overlying relation with the first contoured layer and in a mating contour with a contour of the first contoured layer; and cured adhesive between each the layer to provide fixture of each layer to the other and between individual shattered glass segments of each of the first contoured layer and the second contoured layer to form a consolidated contoured article.

Referring now to the drawings, Figure 1illustrates an exploded view of one embodiment of the present invention. In the illustration, a first sheet of tempered glass 10 is provided in overlying relation with a second sheet of tempered glass 12.
A layer of adhesive represented by numeral 14 is disposed between sheets 10 and 12. A
containment member or holder, shown in the example as flexible sheets 16 and 18 overlie the outside major faces of each sheet 10 and 12. An adhesive (not shown) may be applied to each sheet 10 and 12 or alternatively, the flexible sheet may inherently include adhesive thereon.
The consolidated unit, globally referred to by numeral 20, is shown in Figure 2.
In order to shatter the sheets 10 and 12, an impact device, broadly referenced by numeral 22 is used. It has been found that a conventional punch can achieve desirable results.
The shattering is performed while the adhesive is wet and the flexible sheets 16 and/or 18 may be directly struck with the punch.
Once the degree of shattering has been achieved, the consolidated unit is sufficiently malleable to permit bending, contouring or otherwise shaping.
Containment is facilitated by the flexible sheet and adhesive.
Figure 4 illustrates an example of how the unit 20 may be molded. Molds 24 may be positioned about the unit 20 and remain there until such time as the adhesive has set.
Once this has occurred, the sheets 16 and 18 may be removed to leave a consolidate form taking the shape as shown in Figure 3.
Figures 4 and 4A illustrate the consolidated unit 20 in greater detail and with sheets 16 and 18 removed. As illustrated, the unit 20 comprises a network of individual glass segments 26 with adhesive 14 dispersed therein to form a network of individually bonded segments 26. Depending on the degree of shattering, the interface between the two sheets of glass 10 and 12 may disappear entirely with segments 26 from each sheet 10 and 12 being bonded together at the interface.
Where it is desired that the entire area of each sheet of glass be fractured, the flexible sheets 16 and 18 will cover the full area of each of the major faces of the glass sheets 10 and 12. However, if shattering is selected to be localized, the area to be fractured need only be covered. This embodiment is shown in Figures 5 and 5A.
By providing the flexible sheet material 16 and 18 (18 only shown in Figure 5), localized deformation is possible as illustrated in Figure 5A. A similar procedure tot hat discussed above may be observed to effect this result.
Referring now to Figure 6, a further embodiment of the present invention is illustrated. In this aspect of the invention, a single sheet of tempered glass 10 is employed. The sheet 10 is mounted to a substrate 28 other than tempered glass with adhesive 14 being applied between sheet 10 and substrate 28. Flexible sheet 18 is applied in overlying relation to sheet 18. Shattering or fracture of the glass is achieved as set forth herein previously while the sheet 10 contacts substrate 28. Once the adhesive has set, the sheet 18 may be removed.
The substrate may comprise any suitable surface compatible with the adhesive and impact forces from the fracture of the sheet 10. Plexiglass, non-tempered glass, wood, metal etc. are representative samples.
Referring now to Figure 7, there is shown another example of the invention. In this example, two sheets of glass (10) and (30) are fixed to a contoured mold (24) using an adhesive. Flexible sheet (16) is applied in an overlaying relationship to glass sheet (10). The glass is then shattered as previously described. Once the adhesive sets the flexile sheet can be removed.
Referring now to Figure 8, yet another example of the invention is illustrated. In this example, two glass sheets (10) and (30) are fixed to a substrate (28) using an adhesive. Flexible sheet (16) is applied in an overlaying relationship to glass sheet (10).
The glass is then shattered as previously described. Once the adhesive sets the flexible sheet (16) can be removed.
In order to enhance the aesthetic appearance of the article formed in accordance with the process, coloring agents such as pigments, chips, flakes may be added to, for example, the adhesive. Suitable adhesives for practicing the present process include suitable catalyst type adhesives, ultraviolet curable compounds (UvekolTM), etc.
With respect to the containment achieved by the flexible sheets, the sheets may be individual or comprise a single sheet simply folded about the glass. As an example, the flexible sheet material may comprise vinyl having adhesive on one side. Other materials may be used provided they are easily removed from the glass and permit fracture of the glass to occur. Examples of other useful arrangements for this purpose include materials which are sufficient to provide containment, but which are also easily removed fro the glass. This may be a film material or thicker materials allowing impact for fracture.
As a further alternate embodiment, the shattered glass may be laminated to other surfaces such as ceramic tile, concrete, wood, steel, drywall, fabric and any other surface, thus creating a though sparkling finish to any kind of material.
Although embodiments of the invention have been described above, it is not limited thereto and it will be appreciated to those skilled in the art that numerous modifications from part of the present invention insofar as they do not depart fro the spirit, nature and scope of the claimed and described invention.
