CA2986852A1 - Standalone and self-mounting vibration device for enhanced laminated glass repair - Google Patents

Abstract

An apparatus for greatly enhancing the quality of a vehicle windshield or laminated glass repair, including a sound frequency generator ideally operating in the 50HZ to 1,000HZ range, and suction cup for attachment to the glass surface. The sound frequency generator includes a cylindrical speaker, integrated on/off switch, integrated rechargeable battery, SD card pre-programmed to deliver sound frequencies in a specified frequency range and pattern, mechanically connected suction cup or magnet system for safe and scratch-resistant attachment to the glass surface. The apparatus can also be driven by a custom electronic circuit board which can produce the desired sound frequency range and pattern. The apparatus is used in conjunction with any windshield repair kit using vacuum systems to enable the flow of optically clear resins which harden upon exposure to UV light. The vibrations produced by the apparatus greatly enhance the flow and penetration of the resin into the glass chip or crack.

Description

STANDALONE AND SELF-MOUNTING VIBRATION DEVICE FOR ENHANCED
LAMINATED GLASS REPAIR
TECHNICAL FIELD
The invention relates to apparatus for greatly improving the technique and methods of laminated glass damage repair, more particularly but not exclusively in the field of repair of vehicle glass, which is frequently chipped by flying stones or other material.
BACKGROUND ART
Existing apparatus and methods for repair of damaged vehicle glass involve subjecting a space around the area of damage to a partial vacuum to allow satisfactory penetration of an optically compatible resin into the area of damage, and extraction of air from the resin itself, curing the resin once the damaged area has been filled, and finishing the repair by removing excess cured resin and polishing the surface of the previously damaged area. The quality of the repair depends heavily upon the penetration of the resin into the glass chip or crack, which in turn depends upon the repair kit equipment, the training and skill of the technician, and the type and extent of the damage.
Vehicle glass repair originated in the early 1970s, when laminated glass windshields including a polyvinyl butyrate (PVB) layer became widely available. Glass repair became more widespread with the innovations provided by NOVUS Inc. and the Glass Medic system. During the last 40 years, numerous vehicle glass repair kits have been patented, marketed, and sold under various trade names. Predictions are that windshield glass repair will continue to grow as insurance companies and consumers understand the cost and product benefits. Today windshield repair is an accepted product, not only in the United States, but also within almost every country around the world.
PRIOR ART
The prior art contains two references (U.S. Pat. Nos. 3,562,366 and 6,656,541) to a handheld Ultra-High Frequency (UHF) generating device for effecting a glass repair, but these employ a UHF generator wand that must be held in place by hand, is very expensive, and is largely ineffective because UHF frequencies do not effectively improve resin flow, and they greatly increase the possibility of breaking the glass substrate.
It is apparent that the prior art fails to provide any reference to a standalone, electronic, special sound frequency (ideally 50HZ to 1,000HZ) generating glass-mounted device, that safely produces greatly improved resin flow.

SUMMARY OF INVENTION
The invention pertains to a standalone, easily, and safely glass-mounted vibration apparatus, comprising at least one vibration generator, designed to generate electronic frequencies in a range and repeatable pattern that optimizes the flow of resin into a glass chip or crack;
whereby (a) the vibration apparatus can be attached to any smooth surface with the attachment apparatus, (b) the vibration generator can transmit vibrations to the surface on which it is fixed, (c) any resin injector is also attached to the smooth surface, (d) the smooth surface has at least one cavity (chip or crack) to be filled with resin, (e) the resin injector is used to inject resin inside the cavity of the smooth surface, (f) the vibrations transmitted to the smooth surface by the vibration apparatus will positively influence the flow of the resin, and (g) the vibrations transmitted to the glass surface enable thicker resins to flow to every possible part of the chip or crack, thus ensuring stronger and longer lasting repairs.
The invention provides a means of greatly enhancing the quality and durability of repairing a chip or crack in the laminated glass surface. The use of sound frequencies of a particular range and pattern of sufficient power enables superior flow of the liquid resin into the chip or crack, thereby yielding a better, stronger, more visually esthetic, and longer lasting repair.
The vibrations produced by the frequency generator are ideally in the 50 HZ to 1,000 HZ
range. The applied sound frequencies effect full penetration of the repair resin into the glass flaw, and effectively reduces the viscosity of the resin causing better flow to all regions of the flaw.
In operation, the invention is attached to the laminated glass surface, approximately 10cm from the location of the flaw, by use of the built-in suction cup or magnets.
The apparatus is then turned on, and the repair kit is then activated to release the repair resin as per the kit manufacturer's instructions. The invention enables a much better and deeper penetration of the resin into all parts of the flaw, resulting in a far superior repair.
The repair resin comprises a flowable, viscous, optically transparent resinous material, typically methyl methacrylate, polyester acrylic resin, and/or methacrylic acid. Once properly injected into the glass chip or crack, the resin is subjected to ultraviolet light which hardens and cures it.
TECHNICAL PROBLEM
The quality of any laminated glass repair depends heavily upon the penetration of the resin into the glass chip or crack, which in turn depends upon the repair kit equipment, the training and skill of the technician, and the type and extent of the damage. In particular, a technician without much training or experience will not be capable of producing reliable and long-lasting repairs, nor will the repaired area have a smooth and clear appearance. They might also break the glass surface, necessitating a much more costly replacement.
SOLUTION TO PROBLEM
The invention pertains generally to vehicle glass repair devices, but works perfectly well on any laminated glass surface. More specifically, the invention relates to a revolutionary new standalone vibration device, that easily mounts on any vehicle windshield or glass surface via suction cup or magnets, and that in conjunction with any vehicle glass repair kit, provides an optimal pattern of unique sound frequencies proven to improve the flow of any resin into a glass chip or crack, including higher viscosity, stronger resins. The invention ensures optimal chip repair, every time, regardless of the type of chip, skill of the user, or the repair equipment being used.
ADVANTAGEOUS EFFECTS OF INVENTION
The invention possesses particular benefits and advantages over known vehicle glass repair kits. In particular, the invention provides for a much improved flow of resin than any previous repair device, which typically provide resin flow using vacuum and pressure. The improved resin flow delivered by the invention ensures a much better quality of repair, with many fewer failures. The vibrations transmitted to the glass surface allow for thicker, stronger resins to be used, and for all resins to penetrate to all possible locations of the chip or crack. Additionally, the improved resin flow results in a better visual appearance from both outside the vehicle and inside it. Because the invention is so simple to use, very little training is required, and so an inexperienced repair technician immediately becomes an expert by using the invention. Finally, the time required to complete a repair is shortened, because the invention ensures a more rapid and even flow of the resin to all areas of the chip or crack.
The invention may be used repeatedly for many thousands of times without any fear of wear or failure. The electronic components of the sound generator are of a highly robust design, with zero maintenance and very long life. The suction cup mechanism is of a highly reliable mechanical design, with long-lasting rubber components that clamp onto the glass surface. The magnetic fastening system includes a mechanically mounted round magnet that is covered with a thin layer of fabric such as felt, and placed onto the exterior glass surface, which is then held in place by another similarly shaped magnet also covered in a thin layer of fabric such as felt, which is placed directly under the apparatus on the inside surface of the glass. Magnets are extremely long-lasting and maintenance free.
