The present invention relates generally to portable glass repair kit systems and, more particularly, to a glass repair kit for windshield repair for laminated glass.
Vehicle windshields must be resilient enough to withstand constantly being struck with tiny pebbles, sand, gravel, and other such road debris. Therefore, modern vehicles are equipped with laminated glass. Laminated glass is a type of safety glass which does not completely shatter into dangerous shards upon impact. Laminated glass is formed from two or more thin sheets of tempered glass that are fused to a rubber or plastic central layer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). The outer layers are independent, one on the outside of the vehicle and one on the inside of the vehicle. The central layer acts by absorbing the shock from an impact and reduces the chance of breakage from small particles such as pebbles or the like.
If an object strikes the windshield glass with sufficient force, a chip or crack may be formed. However, the chip is usually localized to only the outer layer of glass. The inside layer of glass within the vehicle is protected from breaking due to the central membrane absorbing the shock of the impact and thereby mitigating further damage to the inside layer of glass. Windshield repair is a viable solution to repair the rock chips that have damaged the outer layer of the glass and prevent further damage, such as cracks spreading from the chip, causing irreparable harm. When done properly, the strength and clarity is sufficiently restored for most safety related purposes.
Prior art glass repair systems are typically complicated involving expensive specialized tools which are not intuitive to operate. These systems advantageously fill cracks or chips in windshields caused from rocks, debris, or other impacts causing damage. Unrepaired damage eventually may permanently damage the windshield as water permeates the layers of glass, causing condensation and decreasing visibility. This may lead to the entire windshield structure being compromised to the point of requiring replacement. Commercial repair kits utilize a special resin which is injected into the center of the chip by first removing moisture, dirt, foreign matter, loose glass, and contamination from the damaged area. The damaged area may then be accessed through probing or drilling to reach the central layer. Resin is then injected using a specialized tool such as a bridge type holding structure having a metal structure with an injector secured to the windshield by suction cups, which offers leveraging and mechanical advantage. The holding structure or bridge holds the injector in place while repairing the damage. The structure controls both pressure on the resin injection and pressure on the glass so that the resin will efficiently fill the crack or chip. After which a vacuum is used to remove air and apply pressure causing the resin to spread and fill the cracks extending from the center of the chip. It is sometimes desirable to be able to quickly repair cracks or chips without the need of visiting a repair center. Repair centers may not be close to a driver's location, open at the time, or may also require a separate visit leading to increased time, effort, and costs.
There exists a need for a glass repair kit that is easy to use for one with little or no skill in repairing windshields, highly portable, and very economical. Consequently, those skilled in the art will appreciate the present invention.

Referring now to the drawings and more specifically to
In this embodiment, housing 108 comprises a top surface 134 and a bottom surface 136. Housing 108 is configured with a central portion capable of retaining porous material 104. Centered within housing 108 is an opening 140 which may be generally circular or other suitable shape depending on the application. The opening could also be configured with perforations or the like that are broken during operation to allow the resin to flow into the glass as discussed herein. The resin is UV (ultraviolet) sensitive so that it begins to harden after being exposed to UV light. UV sensitive resin is readily available and has been used in the prior art for years to fix windshields. In one possible embodiment, adhered to the top surface 134 is a film 138. Film 138 may be vacuum sealed onto housing 108 over porous material 104 thereby creating a pocket 102 retaining porous material 104 within the housing 108. A flexible dome or hemisphere may be created forming the pocket 102 when the film 138 is vacuum sealed to the housing 108. A mold or other means of forming pocket 102 may also be used. Both the film and porous material may therefore be flexible. Pocket 102 may be comprised of flexible, compressible material. Pressing on the pocket 102, which may be a dome shape and created by the flexible film, may then be used to urge or inject the resin into the windshield 124. In one possible embodiment, film 138 may be configured to act as UV shield 112 and therefore a separate UV shield may be omitted. Therefore, film 138 may be opaque and act as a UV shield to block UV light from entering into pocket 102. In another possible embodiment, film 138 may be transparent or translucent and configured to allow UV light to penetrate into a pocket 102, therefore would require a separate UV shield placed over film 138 to block UV light.
In one possible embodiment in which film 138 acts as UV shield 112, film 138 may be permanently adhered to top surface 134. UV light would be blocked from interacting with resin 106 until removal of glass repair kit 100. This would allow resin 106 to flow freely throughout an impact point and cracks to prevent resin 106 from curing prematurely. To completely fill the damaged area may take approximately 5-10 minutes. Once the damaged area has been completely filled in with resin, glass repair patch or kit 100 may be removed. Upon interaction with UV light, resin 106 may cure relatively quickly, for example in 5-10 minutes, making it important to prevent light from penetrating through UV shield 112.
In another possible embodiment, film 138 may be transparent to be configured to allow transmission of UV light into said pocket 102 after removal of a UV shield 112, which is positioned over film 138. In this embodiment, a removable UV shield 112 covers the entire housing. Removable UV shield 112 may be adhered above film 138 and entirely shields pocket 102 from transmission of ultraviolent (UV) light. UV shield 112 may be flexible and removable by peeling apart relative top surface 134 of housing 108.
In another embodiment, the housing may be retained in a UV shielded package, sack, or the like that blocks UV light prior to and during usage so that the housing 108 or pocket 102 does not require a separate removable UV shield mounted to the housing. In another embodiment, removable UV shield 112 may be placed over the pocket 102 only rather than the entire housing 108.
In a preferred embodiment, porous material 104 may be for example a sponge which is placed in the opening 140 of housing 108 whereby when film 138 is vacuum sealed on the top surface 134 of the housing a pocket 102 is formed. Film 138 may be adhered to top surface 134 sealing porous material 104 within housing 108. In another embodiment, porous material 104 may be a sponge, breakable capsule, or other like permeable device operable to retain resin 106 and urge resin during compression. As discussed herein when flexible pocket 102 is compressed then the resin 106 is forced into the impact point 118 or cracks 120 of the glass. In other words, when flexible pocket 102 is compressed, porous material 104 is compressed secreting resin 106 which may be urged or injected through opening 140 into impact point 118 (See
In another embodiment, pocket 102 may remain flush with top surface 134 and be flexible or otherwise compressible to allow compression of pocket 102. For example, pocket 102 could be a cylinder and the top of the pocket, which might be a rigid disk, could act as a piston to compress resin into an impact point. In this embodiment, resin may be stored with or without a permeable material or may simply be placed in the cylinder and may or may not comprise any additional non-porous container such as a capsule. Pocket 102 may also be referred to as flexible pocket or compressible pocket 102.
In the embodiment shown in
In one embodiment, backing 110 may be adhered to bottom surface 136 and seals opening 140 and pocket 102 from being introduced to outside air as well as stopping resin 106 from desiccation prior to use of glass repair kit 100. Adhesive for backing 110 may be sticky but allow removal of backing 110 as discussed below wherein the same adhesive can then be used to adhere housing 108 to the windshield. However, if desired other arrangements such as separate adhesive could be used. Backing 110 may also be secured to bottom surface 136 without adhesives such as by sliding on, snapping on, or the like. Backing 110 is operable to block transmission of UV light from penetrating through opening 140 and into pocket 102. Backing 110 may be flexible and removable by peeling apart from housing 108. In another embodiment, backing 110 may be perforated in an area relative to opening 140. Upon applied pressure to pocket 102, the perforations would break allowing resin 106 to be released through opening 140.
An exemplary embodiment may be comprised of housing 108 formed from high bond double sided acrylic foam tape with an opening 140 created in the center. A porous material 104, such as a sponge, may be inserted into the opening 140. The porous material retains resin 106 within. A film 138 may be vacuumed formed onto top surface 134 and adhered due to an adhesive on both the top and bottom of the housing 108. As film 138 is vacuum formed, a pocket 102 is formed over porous material 104. A backing 110 may be placed on the bottom surface 136 and adhered due to adhesive 114. In this embodiment, the housing remains flexible, lightweight, and relatively thin. Additionally, the adhesive on the bottom surface can be used to both secure backing 110 to the housing and prevent interaction with other surfaces prior to use, as well as, in operation securing glass repair kit 100 to the windshield.

In one embodiment, film 138 is preferably opaque and adhered to top surface 134. Film 138 may configured to not be removable, such that no incidental exposure of light may penetrate pocket 102. UV light reacts with resin 106 allowing resin 106 to harden after the resin flows through opening 140 and into impact point 118 and to the cracks 120 in the windshield. Resin 106 hardens generally quickly after exposure to UV light, such as in a few minutes.
In another embodiment, a separate UV shield 112 may be opaque and above film 138 which may be transparent. UV shield 112 may remain secured to housing 108 while resin 106 may flow into the damaged area. Upon resin 106 completely filling surface pits 118 and cracks 120, then UV shield 112 may be removed. Upon removal of UV shield 112, pocket 102 may be transparent to allow UV light to penetrate to porous material 104 and resin 106.
In another embodiment, a UV shield is used somewhere in housing 108 above pocket 102 and the entire housing 108 is removed in order to expose the resin to UV light.
Backing 110 may be adhered to bottom surface 136 by an adhesive 114. Adhesive 114 may be of a type that is very sticky and forms a seal between the housing and the windshield as discussed hereinafter but may remain soft and relatively removable during clean up. Adhesive 114 may be used to adhere backing 110 to bottom surface 136. Adhesive 114 may also be used to adhere bottom surface 136 to windshield 124 after removal of backing 110. Adhesive 114 may be of the type that does not set or harden, but rather remains pliable and sticky or viscid to secure glass repair kit 100 to a windshield during use but may remain pliable enough to be removed by a user without leaving residue on the windshield after removal of the glass repair kit. Leftover residue may impede a driver's view, therefore having an adhesive that does not leave residue upon removal decreases additional time and work while using glass repair kit 100. Also, it is advantageous to be able to use the same adhesive to secure backing 110 to the housing and also to use the same adhesive to secure the housing to the windshield. However, in other embodiments, adhesive may be applied separately or not at all. In some embodiments, glass repair kit 100 may be secured to the windshield by other means such as suction cups or the like. Other means may also be used to secure glass repair kit 100 to windshield 124 such as sealants, elastomeric seals, synthetic chemicals, cement, paste, glue, tape, epoxies, or the like. Such means to secure glass repair kit 100 to the windshield may also provide a means to provide a seal (for example see
Backing 110 comprises a material operable to block UV light penetration through opening 140 and into pocket 102. Backing 110 may be flexible and peeled off just prior to applying glass repair kit 100 to windshield or glass surface 124. Utilizing backing 110 as a means to retain adhesive 114 makes the kit easier to use without the need to separately apply adhesive.
Referring to
As discussed previously, glass repair kit 100 may further comprise a porous material 104 within pocket 102. Porous material 104 may be a sponge, but may also be any other permeable material capable of retaining resin 106 within. In another possible embodiment, a capsule retaining resin 106 may be utilized wherein applied pressure is capable of breaking the capsule. Upon the capsule breaking, resin 106 may be released to flow. In one embodiment, the porous material and/or sponge may be selected to permit UV light flow therethrough once a removable UV shield is removed.
Housing 108 comprises a top surface 134 and a bottom surface 136. Housing 108 may be formed of a thermoplastic material utilizing a mold, however, other like materials such as other plastics, rubber, or the like that could be flexible yet sufficiently rigid to maintain support for the housing 108 from becoming overly flexible or loose and to maintain a substantially flat configuration. In one embodiment, bottom surface 136 may be coated with an adhesive 114 operable to adhere bottom surface 136 to windshield 124. While it would be possible to apply adhesive separately, in this embodiment, adhesive 114 is already in place on bottom surface 136 underneath backing 110. In one embodiment, bottom surface 136 may be substantially flat or slightly bendable to conform to the windshield. In another embodiment, bottom surface 136 may be curved or have other shapes that are still sufficiently operable to conform to the curvature of windshield 124. Centered in housing 108 and bottom surface 136 may be opening 140. In another possible embodiment, opening 140 may be comprised of a perforated material configured to open with the application of downward pressure. As shown in
During manufacture, porous material 104 may be inserted through opening 140 into pocket 102. Pocket 102 is sufficiently sized to retain porous material within housing 108. As shown in
Referring to
Opening 140 may be placed directly over impact point 118 so as to also align porous material 104 to be above the impact point 118 (See
UV light is required to cure resin 106, therefore UV shield 112 may be removed to allow UV light to penetrate into pocket 102 and interact with resin 106. UV shield 112 may be a thin, flexible plastic or other such material thereby allowing removal from housing 108. UV shield 112 may be removed by peeling from top surface 134 of housing 108. In an embodiment with a removable UV shield, UV shield 112 may be removed after resin 106 has had sufficient time to flow throughout the impact point and cracks. In another embodiment, UV shield is not removable, but rather bonded to housing 108. The entire apparatus may be removed after the resin has filled in the damaged area in order to allow UV light to be transmitted to 106 resin to cure.
Referring to
Housing 108 may be adhered to windshield 124 by adhesive 114 (see, for example,
Once a seal is formed around pocket 102 and opening 140, and preferably over the entire bottom surface 136 of housing 108, with adhesive 114, a user 122 may apply pressure to compress pocket 102 whereby porous material 104 is also compressed. Due to the seal which prevents resin from flowing elsewhere, the resin 106 contained within porous material 104 will then flow through opening 140 and into impact point 118. A relative vacuum, or flow from higher pressure to lower pressure, created by the air tight seal from adhering glass repair kit 100 to windshield 124 further allows resin 106 to flow freely through any remaining cracks or legs 120. When compared to a typical commercial repair center that requires additional heavy tooling, a decreased amount of pressure is required to be applied to windshield 124 thereby mitigating any further damage or cracking from occurring. Greater pressure is often required when utilizing commercial tools and creates a risk of a crack “running” which increases damage, time, and costs associated with repairing a windshield.
As discussed herein, in one possible embodiment, UV shield 112 may be removed from top surface 134, preferably after housing 108 is adhered to windshield 124 and the resin has flowed into the damaged area. Removable UV shield 112 may be a thin, flexible material such as plastic or rubber which may be adhered to top surface 134. UV shield 112 may be peeled off or other like means to be removed from top surface 134 thereby exposing pocket 102 to UV light. UV light is transmitted into pocket 102, through opening 140, and reacts with resin 106 to begin the curing process. Resin 106 may typically cure within approximately 5 to 10 minutes, but may require more or less time as the size of the impact point and cracks are increased or decreased.
In another embodiment, UV shield 112 not be removable but rather may be bonded to top surface 134 of the housing. After user 122 has compressed pocket 102, resin 106 will be urged into the impact point and cracks due to the compression and pressure differential of the vacuum created by the seal 116 from the adhesive 114 between bottom surface 136 and windshield 124. After allowing the resin 106 to flow, user 122 may remove glass repair kit 100 as described below.
In one embodiment, after sufficient time has passed to allow resin 106 to flow, a user 122 may remove glass repair kit 100 by peeling, scraping, or other like means from windshield 124. User 122 may then visually inspect the repair to determine that the impact point and cracks have been sufficiently repaired. A user 122 may also physically inspect the repair such as by carefully running their finger over, using a scraper or flat edge, or other like means to ensure an acceptable repair. In one embodiment, glass repair kit may include a receptacle containing additional resin, scraper, and transparent film such as tape. In the event user 122 determines a repair is not sufficient, such as cracks remain visible or the resin is not even relative to the outer layer 126 of the glass, user 122 may utilize the receptacle to place additional resin. Typically only one drop of resin is necessary, but may be more, for the area that has been determined to be insufficient. After which, clear film or tape may be placed over the area to create an air tight seal and allow the additional resin to flow into the cracks. UV light may then react with the additional resin to cure. Curing time may typically range from a few seconds to 5-10 minutes, but more time may be necessary depending on the size of the remaining damage area. After sufficient time has passed, user 122 may then remove the clear film by peeling and/or utilizing a scraper to remove any leftover adhesive or excess resin to create a smooth surface relative outer layer 126.

After a user has depressed pocket 102 thereby injecting resin 106 into impact point 118, resin 106 flows outward to fill cracks 120. UV light interacts with resin 106 after the resin has flowed to repair the damage in windshield 124. In one possible embodiment, the duration of the curing process may be approximately 5-10 minutes, but may be longer depending on the size and severity of any damage. Larger and deeper impact points 118 and longer, wider cracks 120 may accordingly require increased time to properly saturate and fill the damaged areas. As is shown in
As discussed above, an inspection of the area is recommended to determine if the repair is satisfactory. A visual and tactile inspection may be necessary to determine that resin 106 has cured level with outer layer 126 of windshield 124. If the repair is not level and resin protrudes from the windshield, a scraper may be used to remove excess resin and adhesive from the repaired area. If the repair has not fully filled in the damaged area leaving a depression or nick in the windshield, additional resin may be injected with a transparent film or tape placed over the affected area. UV light may cure the resin will additional time. Upon completion of the curing process, an additional inspection may be made to determine if the repair is satisfactory.

If an object strikes the windshield glass with sufficient force, a chip or crack 120 may be formed. However, the impact point 118 is usually localized to only the outer layer 126 of the windshield 124. As described above, the inner layer 130 is located within the vehicle and is protected from breaking due to the central layer 128 acting as a central membrane absorbing the shock of the impact and thereby mitigating further damage to the inner layer 130 of glass. Windshield repair is a viable solution to repair the impact points or surface pits 118 that have damaged the outer layer 126 of the glass and prevent further damage such as cracks 120 spreading from the impact point 118 causing irreparable harm. When done properly, the strength and clarity is sufficiently restored for most safety related purposes.
As shown in
In summary, during operation of one embodiment of the invention, UV shield 112 remains and backing 110 is removed. In another embodiment, UV shield 112 may also be removable. Housing 108 is positioned on the windshield with pocket 102 directly over the impact point 118. The housing is pressed and smoothed overall and around pocket 102 so that adhesive 114 seals around impact point 118 and opening 140. Once the housing has been pressed to make sure the adhesive is applied, then flexible pocket 102 can be pressed. This forces the resin out of porous material 104 into the cracks of the windshield to thereby prevent the cracks from continuing to run. The UV light will cure the resin with adequate time. In many cases, the resin will cure in a way that the cracks are no longer visible.
The glass repair kit may further comprise additional resin and an injector to inject the resin after removal of the housing as a touch up. Once injected, a piece of transparent tape or the like is placed over the crack wherein the additional resin will fill in any remaining cracks. The glass repair kit may further comprise a scraper to scrape any excess adhesive and resin to provide a smooth surface.
During manufacture of one embodiment, the glass repair kit construction may comprise providing a housing with an opening centrally located relative to the housing. A porous material comprising a resin may be placed within the opening and a film may be vacuum sealed relative to the top surface of the housing creating a pocket containing the porous material and the resin therein. An adhesive may be applied to the bottom surface of the housing and a backing adhered to the bottom surface sealing the porous material within from premature desiccation as well as from interacting with UV light. A UV shield may be provided and adhered to the top surface to block transmission of UV light from penetrating into the pocket to interact with the resin therein.
The foregoing description of the preferred embodiments of the invention has been presented for purposes of illustration and description only.
