Abstract

A decorative applique remover for removing an applique which has been relatively permanently applied, usually by an adhesive, to a substrate as, for example, an enlarged emblem or a pin stripping or other applique on an automotive vehicle or other substrate. The applique remover preferably exists in the form of an abrading disc which is specifically designed to physically engage, lift and remove the applique from the surface of the substrate, such as the surface of an automotive vehicle. The abrading disc is designed with a rubber-like surface capable of literally rubbing the applique from the surface of the substrate without marring or otherwise deleteriously affecting the surface of the substrate, such as the paint of an automotive vehicle surface.

Description

SPECIFICATION

BE IT KNOWN THAT I, ROSS L. SHEPHERD, a citizen of the United States and resident of the City of Burbank, State of Calif., have invented a certain new and useful DECORATIVE APPLIQUE REMOVER of which the following is a specification containing the best mode of the invention known to me at the time of filing an application for Letters Patent therefore.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates in general to certain new and useful improvements in decorative applique removers and, more particularly, to a decorative applique remover for removing an applique from the surface of a substrate without otherwise marring the surface finish of that substrate.

2. Brief Description of Related Art

In recent years, it has become very common to apply applique strips to the side walls of passenger automotive vehicles. These appliques may adopt the form of various types decals which may be in the nature of informative decals, such as police insignia, or otherwise they can be advertising or promotional decals or merely just aesthetic decals. In addition, pins appliques in the form of pin stripping is also frequently applied to the side walls of passenger automotive vehicles.

Appliques, generally formed of vinyl and polyester materials, are also applied to a variety of other surfaces, such as signs, including metal and plastic signs, glass windows, and the like. Moreover, appliques of this type are frequently applied to such items, including surfboards, skateboards, and the like. It may be appreciated that after a period of time the applique becomes marred, particularly on the surfaces of skateboards and surfboards, and in order to refurbish the item, it may be necessary to remove the applique and apply a new one.

One of the main problems in the removal of the applique is that most appliques, particularly after any extended period of time, become exceedingly difficult to remove from the surface of the automotive vehicle or other substrate without damaging or marring that substrate. In addition, and in attempting to remove an applique, so as to avoid damage in or marring the substrate surface, intensive and substantial time consuming manual effort is involved to remove the applique and still avoid damage to the surface finish of the item from which it is removed. In the case of a surfboard, and particularly one formed of reinforced plastic surface, it may quite difficult, if not impossible, to correct a marred surface finish.

In the case of public vehicles, such as police vehicles, these vehicles are frequently stripped of their radios, gun racks and the like and the exterior police identification must necessarily be removed before sale or other disposition of these vehicles, typically at municipal auctions therefor. Again, removal of a large applique which may extend across most of the side panel of a door must take place without marring or otherwise damaging the paint surface.

In the automotive industry, these appliques are frequently in the nature of stripes which are identified in that industry as pinstripes, as stated above. These pinstripes are of relatively narrow width and extend for a substantial distance across the length of the automotive vehicle. Appliques are also frequently applied to side walls of trucks, including both truck cabs, trailers and the like.

There have been various attempts to remove appliques from surfaces of automotive vehicles and other substrates and not the least of which is with the use of solvents. However, after an applique has been applied to a substrate for a period of time, the use of a solvent is not very effective. There have also been attempts to use various types of scrapers for literally prying the applique from the surface of the substrate. One of the techniques frequently used for removal of appliques is to apply heat to the applique. Typically, a torch, such as a gas fired torch, having a temperature of about 1200° F., is used to heat the applique causing a softening thereof and which is then removed with a scraper. However, it can be envisioned that, to the extent that the surface finish is not marred by the 1200° F. flame, it is frequently marred by the scraping of the vinyl from the surface of the vehicle or other substrate. The 1200° F. flame, if not used exceedingly carefully and if used on an automotive vehicle, will cause the paint on the vehicle to burn and this will again result in need for repainting of a portion of the vehicle. The inevitable result is that there is usually some scratching or other mar to the surface finish of the vehicle and this, of course, militates against and hampers the purchase price of that vehicle in a later sale.

There have also been attempts to use solvents for softening and otherwise removing, if not completely dissolving, the vinyl applique on a finished surface. However, relatively strong solvents are needed to attack a vinyl material. Consequently, very strong solvents, such as carbon tetrachloride or carbonticholoride can be used for this purpose. However, these solvents also have a tendency to soften the surface of the finish and to discolor the surface of the substrate. Moreover, the strong solvents are not only environmentally unfriendly, but they can be quite hazardous to human personnel who are required to use same. Disposal of these solvents also becomes a critical problem with present governmental regulations.

Another one of the present techniques which has been widely used for removal of an applique from a substrate is that of an abrading disc. However, and here again, the commercially available abrading discs or so-called wheels are not very effective in removing the applique without removing a portion of the surface finish. If the abrading disc is designed so as to avoid damage to a paint finish, then it is not effective as a remover of the applique.

Heretofore, there has not been an effective means to remove an applique from a substrate, such as an automotive vehicle or other substrate and, particularly, a metal substrate having a surface finish thereon.

OBJECTS OF THE INVENTION

It is, therefore, one of the primary objects of the present invention to provide a device for removing an applique from a surface of an substrate without otherwise damaging the surface finish of that substrate.

It is another object of the present invention to provide an abrading disc which can be used for lifting and removing an applique from a surface of a metal substrate without otherwise marring or damaging the surface finish of that substrate.

It is a further object of the present invention to provide an abrading disc of the type stated in which the wheel of the disc is constructed so that it can be mounted to a drive, such as a motor, for rotating same without enabling other components of that abrading disc to come into contact with the surface of the substrate from which an applique is being removed.

It is an additional object of the present invention to provide an abrading disc of the type stated which is constructed of a material which is effective to remove various sizes and shapes of appliques from the surface of an automotive vehicle without damaging the surface finish of that automotive vehicle.

It is another salient object of the present invention to provide a method of removing an applique from the surface of a substrate quickly, easily and effectively without consuming a substantial amount of manual labor and which does not otherwise mar the surface finish of the substrate from which the applique is being removed.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement and combination of parts and components present described and points out in the claims.

BRIEF SUMMARY OF THE INVENTION

A decorative applique remover for removing an applique from a surface of a substrate and, particularly, a metal or reinforced composite substrate. More particularly, in one embodiment, the invention relates to the removal of an applique from an automotive vehicle. The appliques which are normally applied to automotive vehicles are generally decorative in nature. However, in many cases, the appliques are provided for functional purposes, such as identifying an ambulance, police vehicle, etc. Nevertheless, these appliques are still decorative in nature and, hence, the term “decorative applique” in accordance with the present invention will include appliques which have more of a functional purpose to them.

The appliques which are generally applied to the surface of automotive vehicles and other substrates are generally formed of thin plastics, although they may be formed of plasticized paper materials. The thin plastics are preferred, since they are generally resistant to degradation from weathering and readily and easily accept an adhesive for application to the surface of a substrate, such as a wall of an automotive vehicle. The exact nature of the applique is not critical in accordance with the present invention. However, it is pointed out that the applique usually has a very thin wall construction and, hence, it is difficult to remove by buffing from the wall of an automotive vehicle without otherwise damaging the underlying surface paint.

The present invention provides an abrading disc which can be rotated, such as by a hand held buffer-grinder or a sander, or the like, at required speeds to effectively lift and remove the applique from the surface of the substrate. Surprisingly, with the device of the prevent invention, this disc does not mar or damage the surface of the substrate to which the applique has been provided without marring a substrate.

It should be understood in connection with the present invention that the applique remover is described in connection with removal of appliques from automotive vehicles, since these appliques are widely applied to automotive vehicles. However, it should also be understood that the present invention is not so limited and the applique remover can be used for removal of appliques from essentially any type of substrate where it is necessary to remove the applique without otherwise damaging the surface finish of that substrate.

The term “abrading” is used in a broad sense and is not limited to a mere polishing or cleaning operation. It similarly does not encompass a hard brush-like action which would occur in many cleaning operations. Rather, the term is used in a sense which represents more than a simple buffing or polishing action to include the actual lifting of an applique from a substrate surface without a hard abrasion. This substrate surface may adopt the form of a metal surface, reinforced composite surface, a plastic surface, or the like.

The applique remover of the present invention comprises a disc in the nature of a buffing disc having an applique removal surface composition formed of an elastomer and, particularly, a blended urethane material. In accordance with the present invention, it has been found that the compositions used for making a normal pencil eraser is actually highly effective for removal of appliques from surfaces of automotive vehicles. Indeed, it would not be anticipated that one would expect to find a pencil eraser effective in the removal of a plastic applique from a metal surface. Nevertheless, tests have revealed that a material similar to an eraser is highly effective in not only lifting and removing the applique but does so without substantially any damage whatsoever to the paint finish or other finish on the surface of the vehicle.

It has also been found that when a solvent, including many known organic solvents, is first used to impregnate the applique, removal with the buffing disc of the present invention becomes more efficient. Well known solvents are highly effective for this purpose, although care must be taken to avoid any hazardous vapors from such solvents. If the solvent is applied merely by a hand applicator and allowed to penetrate into the applique, removing the applique becomes relatively simple and easy.

The present invention does utilize a solvent which can be employed to remove the vinyl applique after abrading thereof. The solvent which is employed is that known as a D-limoline solvent which is a citrus based solvent. This solvent does not otherwise affect the substrate.

It is possible to use many types of elastomer materials, such as eraser compositions, when modified to have proper resilience and hardness, as previously stated. However, the material must be sufficiently durable so that it does not quickly wear down requiring frequent replacement. It may be appreciated that if the abrading material wears unduly fast, an inattentive operator could allow other portions of the buffing instrument to contact the metal paint of the vehicle, such as a bare portion of the rotating disc or the like. This would indeed damage the surface finish of the automotive vehicle. Further, undue wear of the abrading material would require frequent replacement and the attendant down time.

The abrading disc is constructed so that a metal plate having a hub for mounting on a rotatable shaft is provided. The hub is on the outer surface of the buffing wheel so that it does come into contact with the metal or other surface on which the applique exists. The metal plate and the side of the metal plate which would be used to remove the applique is entirely covered with the abrading material, such as the urethane material mentioned above. As a result, the only exposed portion of the abrading disc which could contact the surface of the automotive vehicle or other surface and the applique is that applied urethane buffing material. As indicated above, the hub is on the opposite side and therefore not accessible to be engaged with the surface of the automotive vehicle.

The plate is provided with a series of openings along its periphery so that the urethane or other buffing material when applied, particularly in a liquid form, will immediately bond to both sides of that plate and entirely cover the plate.

In addition, a red plastic alert element is incorporated in the urethane material adjacent to the metal plate. Thus, when the urethane material wears down to the point where the red warning element becomes visible, the user is effectively warned that the disk should be replaced. Otherwise, continued use thereof could result in damage to the surface finish of the item from which the applique is removed.

This invention possesses many other advantages and has other purposes which may be made more clearly apparent from a consideration of the forms in which it may be embodied. These forms are shown in the drawings forming a part of and accompanying the present specification. They will now be described in detail for purposes of illustrating the general principles of the invention. However, it is to be understood that the following detailed description and the accompanying drawings are not to be taken in a limiting sense.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Referring now in more detail and by reference characters to the drawings, which illustrate a preferred embodiment of the present invention, A designates a decorative applique remover which can be used for removing a decorative applique from the surface of a substrate, such as a surface of an automotive vehicle. [0039]
The term “automotive vehicle” is used in a broad sense to include both passenger automotive vehicles, pick-up trucks, truck cabs and trailers and the like. Essentially, the term is used to include essentially any type of road driven movable vehicle, whether or not a driven vehicle or one which is pulled in the nature of a trailer. It is to be understood, however, that the invention is not only limited to automotive vehicles, but can be used for removing appliques from other vehicles, such as boats, airplanes, and the like, as well as from other movable and stationary objects. The invention is also effective in removing appliques from a variety of other substrates including, for example, surfboards, refrigerators, truck trailers, and numerous other substrates. [0040]
The applique remover of the present invention exists in the form of an abrading disc, as aforesaid, and comprises an inner relatively [0041] rigid base plate 10 which serves as a structural element. The plate has a relatively flat upper surface 12 and a relatively lower surface 14. The disc is also formed with an integral upstanding centrally located hub 18, as best shown in FIG. 3. The plate 10 is preferably formed of a light weight relatively rigid plastic material, although it may be formed of an aluminum, steel or other structural material to provide rigidity and body to the disc.
Applied to both the [0042] upper surface 12 and the lower surface 14 of the disc 10, as well as the central hub 18, is an elastomeric material having an upper section 20 and a lower section 22, in the manner as best shown in FIG. 3 of the drawings. The upper section 20 is integrally connected to the lower section 22 by means of integral elastomeric projection sections 24 extending through openings 26 formed in the plate 10. In this way, the upper elastomeric upper section 20 and lower elastomeric section 22 become integral with one another. In addition, the two portions 20 and 22 are bonded by a peripheral angularly extending end portion 28 of the same elastomeric material and extending around a peripheral edge 30 of the plate 10. In effect, the upper and lower sections and end section therefore are really a single, integral piece of material which merely defines upper and lower layers and a peripheral layer on the disc itself. Thus, there is only one single elastomeric material.
In the embodiment of the invention as shown in FIG. 3, it can be observed that the elastomeric section is provided with a relatively flat [0043] upper surface 36 and an integrally formed upwardly and inwardly diverging arcuate side wall 38 which merges into a relatively flat top wall 40. The lower section 22 similarly has an downwardly and inwardly projected truncated side wall 42 and a flat centrally located bottom surface 44.
In the embodiment of the invention as shown in FIG. 3, it can be observed that the relatively [0044] flat side wall 42 is somewhat arcuately shaped and constitutes a relatively large surface area of the lower section 22. This slightly arcuate surface 42 actually serves as the preferred buffing surface. The relatively flat bottom surface 44 is relatively small, since it is not used in the buffing operation.
The [0045] disc 10 is provided with the enlarged openings 26, as aforesaid. In the preferred embodiment, the plate 10 is somewhat pentagonal in shape with rounded corner portions, although other shapes could be used. The three such openings 26 are provided and are generally located at the apex of an imaginary equilateral triangle each of these three corner portions, as best shown in FIG. 1 of the drawings.
Three additional [0046] smaller diameter openings 46 may also be formed in the plate 10 and in the central hub 18 in order to further provide for integral bonding of the upper and lower sections around the hub. Again, although three such openings 46 are illustrated, it should be understood that the number of openings and the exact location thereof is not critical in accordance with the present invention.
A plurality of brightly colored elements, three as shown, are also located in slightly spaced apart relationship to and preferably on the bottom surface [0047] 14 of the disk 10. In place of the plurality of elements 50, a bright plastic thin layer could be included for this purpose. Moreover, the thin layer or plurality of elements may be in the form of a relatively thin film and is completely incorporated within the resin material surrounding the disk 10. However, the resin is somewhat translucent. Not withstanding, when a user of the device first observes the red colored layer 50, which will become apparent when the abrading material has been removed or worn down to within a few mills of that layer, the user is alerted to the fact that he or she must change the abrading disk 10 for a new one in order to potentially avoid damage to the substrate surface.
Again, it can be observed that the urethane buffing material and, particularly, the upper section [0048] 16 thereof, is disposed completely over the plate and fully encloses the plate 10. The central hub 18 of the plate 10 is also provided with an opening to receive a fitting 52 and which is, in turn, provided with a threaded interior central bore 54 for receiving a shank of an instrument, such as that shank 56 illustrated in FIG. 3 of the drawings. A washer 58 is disposed on the upper surface of the fitting 52 and is similarly provided with an opening 60 matching the opening 54 to thereby allow receipt of the shank 56. Moreover, and by further reference to FIG. 3, it can observed that the washer 58 is flush with the upper surface 40 and is retentively held in place by the urethane material.
The driving instrument on which the disc of the present invention is used may adopt the form of a hand held buffer, grinder or sander. One [0049] such instrument 70 is more fully illustrated in FIG. 4 of the drawings. In this case, it can be observed that the instrument 70 is provided with an elongate hand holding section 72, a pistol grip handle 74, with an actuating trigger 76. The forward end of the instrument 70 is provided with an externally threaded shaft 56 which is adapted to fit within the aligned openings 54 and 60. In this way, the disc may be threadedly secured to the shank 56.
The urethane material, which is hereinafter described in the more detail, is typically applied to the disc in a die. When the [0050] plate 10 is provided, it is inserted into a die and the urethane is effectively introduced into the die cavity and secured to the disc in the manner as previously described. Moreover, and in accordance with this construction, it is possible to insure that the abrading material covers the lower portion of the disc and to insure a sufficient thickness of buffing material is formed on the plate 10.
The material, which is applied to the disc, is preferably initially in liquid form. Typically, the material must be heated until the urethane or other material achieves a liquid temperature. Formation in a die is almost always preferred, since it is possible to control the amount of time that the disc remains in the die and to insure that the abrading material fully covers the disc in the desired locations and it insures a sufficient thickness of buffing material on the surface of the applique remover. [0051]
As indicated previously, urethane materials are highly effective for use as the abrading material. Some of those abrading materials which have been found to be highly effective in the present invention include the elastomeric polyurethanes and, particularly, those urethanes with a polyether polyol and a urethane elastomer. Some of these urethanes may be formed with a hydroxy terminated polyol, such as, for example, oxyalkylene. [0052]
Other elastomeric compounds which can be used are chosen from suitable polycarbonates, polyethylene therephthalate, polypropylene, polyesters, polyamides, polyimides, polyvinyl chloride, acrylic resins, alkyd resins, and the like. These urethanes approach the feel and characteristics of a paper eraser, but have been found to be highly effective in the removal of vinyl like products. [0053]
Thus, there has been illustrated and described a unique and novel decorative applique remover and which thereby fulfills all of the objects and advantages which have been sought. It should be understood that many changes, modifications, variations and other uses and applications which will become apparent to those skilled in the art after considering the specification and the accompanying drawings. Therefore, any and all such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by the invention. [0054]
