The present disclosure relates to an adhesive removal tool, more specifically, but not by way of limitation, more particularly to a rubber wheel coupled to a fastener that is optionally coupling to a power tool for removing adhesive on painted and non-painted automotive parts.
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Currently there is no adhesive remover wheel on the market that is specifically made for moldings and current adhesive wheels do not remove adhesive from painted plastic panels without damaging the painted finish. Typically, a scrape with a razor and a degreaser is employed to remove adhesive, which tend to be fairly bulky and unable to get into tight crevices. Furthermore, exterior plastic body panels are on the rise and current adhesive wheels fail to remove adhesive without damaging paint.
U.S. Pub. No. 2006/0218739 A1 (Hsu) discloses a wheel having several equidistantly spaced apart gaps on each of the annular edges of two sides thereof, and a tooth-shaped portion between every two adjacent ones of the gaps; when the wheel is turned while being pressed against an object, which has adhesive on the surface, the adhesive will be removed; because the gaps are formed, when the wheel is used to remove adhesive from the surface of an object, the area of contact between the wheel and the object won't be too large, and in turn damage of the surface of the object is prevented, and the wheel will wear down more slowly. Shortcomings include a lack of durability, and the wheel isn't manufactured from EPDM to ensure prevention of damaging paint or plastic during the adhesive removal.
U.S. Pub. No. 2011/0225749 A1 (Wang) discloses an eraser wheel for cleaning viscose, which comprises an eraser wheel body and a coupling member. The eraser wheel body has an axial hole and a plurality of slots thereon. The axial hole is located at a central portion of the eraser wheel body. The slots are located beside the axial hole. The coupling member includes a coupling axle and a plurality of coupling ribs. One end of the coupling axle is provided with a connecting unit, and another end of the coupling axle is connected with the coupling ribs. The coupling axle is inserted through the axial hole. The coupling ribs are positioned in the slots. Accordingly, it is only required to replace with a new eraser wheel, without making a replacement of the coupling member. Besides, the eraser wheel can be produced alone, which simplifies the production procedure. Shortcomings include an inability to easily assemble and disassemble for maintenance and replacing parts, a lack of durability, the eraser isn't manufactured from EPDM to ensure prevention of damaging paint or plastic during the adhesive removal and the eraser isn't lightweight.
U.S. Pat. No. 5,259,914 A (Fisher) discloses a portable vehicle adhesive remover having a motor unit assembled inside a housing including a throttler, a rotor and a gear assembly where the motor unit has an elongated spindle extending out from the top opening of the housing; an extending shank having a proximal end attached to the elongated spindle of the motor unit and a distal end; and an eraser unit attached to the distal end of the extending shank including a resilient eraser member and a disc member embedded in the eraser member. When the eraser unit and the motor unit are attached and a high pressure compressed air is sent into the bottom opening of the housing, the compressed air will be gushed into the rotor by the throttler assembly, which in turn will drive the eraser unit through the gear assembly and cause the resilient eraser member to rotate at a high speed. When a high-speed rotating eraser member is engaged to pinstripes, decals, side moldings and other adhered items, it can generate adequate heat to cause the adhesive to lose its adhesion and thus release the pinstripes, decals, side moldings and other adhered items, so they can be removed without damaging the paint or other body parts of the vehicle. Shortcomings include an inability to easily assemble and disassemble for maintenance and replacing parts, a lack of durability, the portable vehicle adhesive remover isn't manufactured from EPDM to ensure prevention of damaging paint or plastic during the adhesive removal, lacks the ability to be operated manually and the portable vehicle adhesive remover isn't lightweight.
U.S. Pat. No. 5,856,396 A (Vipperman) discloses a method of manufacturing rubber wheels and composition therefor used on a portable vehicle adhesive remover for removing pinstripes, decals, side moldings and other items adhering to a vehicle without damaging the original paint of the vehicle. Shortcomings include an inability to easily assemble and disassemble for maintenance and replacing parts, a lack of durability, the rubber wheel isn't manufactured from EPDM to ensure prevention of damaging paint or plastic during the adhesive removal, lacks the ability to be operated manually and the portable vehicle adhesive remover isn't lightweight.
U.S. Pat. No. 5,879,504 A (Winter) discloses a soft elastomeric disc for removal of polymeric compositions from an underlying substrate. The disc is useful for removing decorative decals, stripes, graphics, emblems, protective moldings, paint and adhesive and is made from a filled elastomeric composition. The elastomeric composition is filled with a system that combines an organic lubricant and a non-abrasive particulate. Shortcomings include an inability to easily assemble and disassemble for maintenance and replacing parts, a lack of durability, the soft elastomeric disc isn't manufactured from EPDM to ensure prevention of damaging paint or plastic during the adhesive removal, lacks the ability to be operated manually and the soft elastomeric disc isn't compact enough to perform in tight spaces and isn't lightweight.

Each of the discs includes an annular lip disposed in the cavity in a related one of the sides of the rotary eraser and at least one block disposed in the recess in the related side of the rotary eraser. The threaded bolt is inserted through the rotary eraser and the discs. The nut is engaged with threaded bolt. Shortcomings include an inability to easily assemble and disassemble for maintenance and replacing parts, a lack of durability, the rotary eraser isn't manufactured from EPDM to ensure prevention of damaging paint or plastic during the adhesive removal and isn't lightweight.
U.S. Pat. No. 8,007,347 B1 (Lampka et al.) discloses a rotary abrading tool of the erasure-type. The invention includes a wheel assembly comprising an annular eraser wheel having an outer crown of radially directed teeth, a central core of an elastomeric material that radially expands during operation, and a pair of discoid hubs secured on opposite axial ends of the eraser wheel. The teeth of the eraser wheel are helically arranged. Shortcomings include an inability to easily assemble and disassemble for maintenance and replacing parts, a lack of durability, the rotary abrading tool isn't manufactured from EPDM to ensure prevention of damaging paint or plastic during the adhesive removal, lacks the ability to be operated manually and the rotary abrading tool isn't lightweight.
U.S. Pat. No. 8,286,291 B2 (Lampka et al.) discloses a two-piece eraser assembly, including an eraser disk and an eraser hub for mounting and holding the eraser disk. The eraser hub includes upper and lower surfaces a flange at the peripheral edge of the hub and a stub shaft on the lower surface positioned axially with a through bore. The eraser hub includes a plurality of spaced apertures for engaging with and detachably locking eraser disk extensions on the backside. The upper surface of the eraser disk includes a central recess and an aperture in the recess. The eraser disk includes a plurality of abrading teeth running radially from the central recess. The lower surface of the eraser disk further comprises a plurality of mounting elevations keyed for engaging with the spaced apertures or slots in the eraser hub for securely locking the eraser disk to the eraser hub.
