Portable vehicle adhesive remover for removing pinstripes, decals, side moldings and other adhered items from a vehicle

The present invention is a portable vehicle adhesive remover having (a) 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; (b) an extending shank having a proximal end attached to the elongated spindle of the motor unit and a distal end; and (c) 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 the 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.

BACKGROUND OF THE INVENTION 
1. Field of The Invention 
The present invention relates to the automobile and other vehicle 
manufacture and service industries. More particularly, the present 
invention relates to portable power tools designed and built for removing 
vehicle adhesive to remove pinstripes, decals, side moldings and other 
adhered items from a vehicle. 
2. Description of The Prior Art 
In automobile and other vehicle manufacture and service industries, people 
often need to remove pinstripes, decals, side moldings and other adhered 
items from the bodies of vehicles such as trucks or automobiles. 
Traditionally it is done by peeling, scratching or sanding off the 
pinstripes, decals, side moldings, etc. However, these traditional methods 
usually leave damage the original paint on the bodies of the vehicles. 
There is a significant need for an improved method to remove the 
pinstripes, decals, side moldings and other adhered items from a vehicle 
without damaging the paint on the vehicle. 
SUMMARY OF THE PRESENT INVENTION 
The present invention is a portable vehicle adhesive remover for removing 
pinstripes, decals, side moldings and other adhered items from a vehicle 
without damaging the paint or other body parts of the vehicle. 
It has been discovered, according to the present invention, that if the 
adhesive used for holding pinstripes, decals, side moldings and other 
adhered items on the paint or other body parts of a vehicle is heated, 
then it will lose its adhesion and thus release the pinstripes, decals, 
side moldings and other adhered items from the vehicle without damaging 
the paint or other body parts of the vehicle. 
It has also been discovered, according to the present invention, that if a 
vehicle adhesive remover having a circular eraser member rotating at high 
speed is engaged to the various adhered items on a vehicle, then the 
friction between the rotating eraser member and the adhered items can 
generate heat which in turn will warm up the adhesive and cause it to lose 
its adhesion. 
It has further been discovered, according to the present invention, that if 
the high speed rotating eraser member of the vehicle adhesive remover is 
made of rubber type material, then it will most effectively generate heat 
when it is frictionally engaged to the adhered items on the body of the 
vehicle. 
It has additionally been discovered, according to the present invention, 
that if the high speed rotating rubber type eraser member of the vehicle 
adhesive eraser is rotating at a speed approximately between 3,000 rpm and 
4,000 rpm, then the heat generated by its rotational engagement with the 
adhered items on the body of the vehicle is sufficient to cause the 
adhesive to substantially lose its adhesion and the adhered items will 
easily come off without damaging the paint on the vehicle. 
It has also been discovered, according to the present invention, that if a 
specialized metal disc member attached to the rotation shaft of the motor 
unit is embedded into the rubber type erasing member of the vehicle 
adhesive remover, then the disc member can best prevent the rubber type 
erasing member from slipping relative to the rotation shank of the motor 
unit and can also easily replace worn out eraser members. 
It has further been discovered, according to the present invention, that if 
the eraser unit of the vehicle adhesive remover is designed to be quickly 
detachable from the motor unit, then a user can use different sized 
erasers with one motor unit. 
It has additionally been discovered, according to the present invention, 
that if the motor unit of the vehicle adhesive eraser has an air die 
motor, then it can utilize compressed air as its power source, which is a 
very popular and convenient power source for the tools used in the 
automobile manufacture and service industries. 
It is therefore an object of the present invention to provide a vehicle 
adhesive remover, which can cause the adhesive used for adhering 
pinstripes, decals, side moldings and other adhered items on the paint or 
other body parts of a vehicle to lose its adhesion, so that the 
pinstripes, decals, side moldings and other adhered items can be removed 
from a vehicle without damaging the paint or other body parts of the 
vehicle. 
It is also an object of the present invention to provide a vehicle adhesive 
remover, which has a circular eraser member rotating at high speed and 
engaged to the various adhered items on a vehicle, so that the friction 
between the rotating eraser member of the vehicle adhesive eraser and the 
adhered items on the vehicle can generate heat which in turn will warm up 
the adhesive and cause it to lose its adhesion. 
It is a further object of the present invention to provide a vehicle 
adhesive eraser, where the high speed rotating eraser member of the 
vehicle adhesive remover is made of rubber type material, so that it will 
most effectively generate heat when it is frictionally engaged to the 
adhered items on the body of the vehicle. 
It is an additional object of the present invention to provide a vehicle 
adhesive eraser, where the high speed rotating rubber type eraser member 
of the vehicle adhesive remover is rotating at a speed approximately 
between 3,000 rpm and 4,000 rpm. Then the heat generated by its rotational 
engagement with the adhered items on the body of the vehicle is sufficient 
to cause the adhesive to substantially lose its adhesion and the adhered 
items will easily come off without damaging the paint on the vehicle. 
It is also an object of the present invention to provide a vehicle adhesive 
eraser, where a specialized metal disc member attached to the rotation 
shaft of the motor unit is embedded into the rubber type erasing member of 
the vehicle adhesive remover, so that the disc member can best prevent the 
rubber type erasing member from slipping relative to the rotation shank of 
the motor unit. 
It is a further object of the present invention to provide a vehicle 
adhesive eraser, where the eraser unit of the vehicle adhesive remover is 
designed to be quickly detachable from the motor unit. Then a user can use 
different sized erasers with one motor unit and can also easily replace 
worn out eraser members. 
It is an additional object of the present invention to provide a vehicle 
adhesive remover, where the motor unit of the vehicle adhesive eraser has 
an air die motor, so that it can utilize compressed air as its power 
source, which is a very popular and convenient power source for the tools 
used in the automobile manufacture and service industries. 
Further novel features and other objects of the present invention will 
become apparent from the following detailed description, discussion and 
the appended claims, taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Although specific embodiments of the present invention will now be 
described with reference to the drawings, it should be understood that 
such embodiments are by way of example only and merely illustrative of but 
a small number of the many possible specific embodiments which can 
represent applications of the principle of the invention. Various changes 
and modifications obvious to one skilled in the art to which the invention 
pertains are deemed to be within the spirit, scope and contemplation of 
the invention as further defined in the appended claims. 
Referring to FIG. 1, there is shown a perspective view of a portable 
vehicle adhesive remover 10. It has a motor unit 12 which has an air 
exhaust port 14 and a throttle control lever 16 at the bottom end, and a 
rotatable extending shank 18 at the top end. An eraser unit 20 is 
detachably attached to rotatable shank 18. Eraser unit 20 has a disc 
shaped rubber eraser member 22 having a flat transverse erasing surface 
24. Rotatable extending shank 18 may be detached by using pliers to hold 
both the nut 26 of motor unit 12 and the nut 28 of extending shank 18 and 
then turn them in opposite directions. Eraser unit 20 can be detached by 
hand holding rubber eraser member 22 and holding top nut 28 of extending 
shank 18 with a pair of pliers and then turning them in opposite 
directions. 
Referring to FIG. 2, there is shown an exploded view of motor unit 12 of 
portable vehicle adhesive remover 10. Motor unit 12 has a hollow 
cylindrical housing 114. Near the bottom end of housing 114 there are two 
opposite side openings and one bottom opening. An air exhaust sleeve 111 
is attached to the bottom opening with an "O" ring 112 and a retainer ring 
113 inserted. A throttler assembly is assembled inside the bottom portion 
of housing 114, a rotor assembly is assembled inside the middle portion of 
housing 114, and a gear assembly is assembled inside the top portion of 
housing 114. 
The throttler assembly includes an air regulator 104, a valve stem 107 and 
a valve bushing 108. One end of valve stem 107 is inserted with a spring 
105 into air regulator 104 with an "O" ring 106, so that spring 105 tends 
to push valve stem 107 out to block the air passage through air regulator 
104. The other end of valve stem 107 is stuck out from one of the side 
openings through valve bushing 108 which is in turn mounted on the side of 
housing 114 at the side opening. Air regulator 104 is assembled inside 
housing 114 and supported by a valve screw 101 with an "O" ring 103 
inserted which is in turn mounted on the side of housing 114 at the other 
opposite side opening with an "O" ring 102 inserted. A throttle lever 109 
is attached by a roll pin 110 to the side of housing 114 near the bottom 
end against the stuck out end of valve stem 107. 
The rotor assembly includes a cylinder 120 and a rotor 119 which has four 
side slots with blades 118 mounted respectively. Rotor 119 is supported by 
front ball bearing 122 and rear ball bearing 115 and assembled inside 
cylinder 120. Front end plate 121 and rear end plate 116 are assembled to 
the respective ends of cylinder 120 by two roll pins 131 and 117 
respectively. 
The gear assembly includes an internal gear 124 and planet cage 125 which 
has two side slots with planet gears 128 mounted respectively by planet 
pins 129. Planet cage 125 is supported by two ball bearings 126 and 123 
and assembled inside internal gear 124 with a wave washer 132 and two idle 
gears bushings 127 engaged with the two planet gears 128 respectively. 
Finally a housing cap 130 is screwed on top of housing 114 and the upper 
shaft of the planet cage sticks out from the top opening of housing cap 
130 for receiving a cap nut 26 and a hollow extending shank. Shown in 
detail in FIGS. 3 and 4, extending shank 18 has inner screw threads 51 and 
53 at its upper end 52 and lower end 54 respectively. The inner screw 
threads 51 at upper end 52 of extending shank 18 receives the eraser unit 
shown in FIG. 6. Lower end 54 of extending shank 18 is threaded onto the 
stuck out upper shaft of planet cage 125 of the gear assembly by lower 
threads 53. The outer periphery of the upper end of extending shank 18 is 
configured as a nut 28 for accommodating a pair of pliers. The outer 
periphery of the middle portion of extending shank is also configured to 
have two oppositely disposed flat surfaces 56 and 58 for accommodating a 
pair of pliers. 
Referring now to FIGS. 5-8, there is shown the eraser unit 20 of the 
present invention portable vehicle adhesive remover 10. FIG. 5 is an 
exploded view of eraser unit 20, FIG. 6 is a perspective view of eraser 
unit 20, FIG. 7 is a cross-sectional view of eraser unit 20 taken along 
line 7--7 of FIG. 6, and FIG. 8 is a perspective view of the novel disc 
member of eraser unit 20. 
Eraser unit 20 has a disc-shaped rubber eraser member 22 having a flat top 
erasing surface 24, and a disc member 30 embedded inside eraser member 22. 
Disc member 30 includes a disc 32 having a central opening 34 and two rim 
notches 36 and 38, a bolt 40 having an elongated shaft 42, a washer 44 and 
a nut 46. The elongated shaft 42 of bolt 40 extends through the central 
opening 34 of disc 32 and is secured by nut 46 with washer 44 inserted. 
When molding the rubber eraser member 22 with the disc member embedded, 
the rubber material will fill in the two rim notches 36 and 38 of disc 30, 
so that rubber eraser member 22 will not slip relative to disc 30 during 
rotational motion. After molding, only the elongated shaft 42 of bolt 40 
is exposed out of rubber eraser member 22, which is in turn engaged with 
the upper end 52 of extending shank 28 of motor unit 12. 
When high pressure compressed air is sent into the bottom end 14 of motor 
unit 12 and throttle control lever 16 is pressed, the compressed air will 
be gushed into the rotor assembly through the throttler assembly and blow 
blades 118 to make rotor 119 rotate, which in turn drives extending shank 
18 to rotate through the gear assembly. Consequently rubber eraser member 
22 is rotated by embedded disc member 30, and its erasing surface 24 can 
be engaged to pinstripes, decals, side moldings and other adhered items on 
vehicle bodies. By using pliers eraser unit 20 can be detached from motor 
unit 12, which enables a user to use alternative eraser units having 
different sized erasing surfaces with one motor unit. When the rubber 
erasing member is engaged to the vehicle pinstripes or decals or the 
adhesive holding side molding to a vehicle, the high velocity rotation of 
the rubber erasing member will generate adequate heat to cause the vehicle 
adhesive to lose its adhesion and thus release the pinstripes, decals, 
side moldings and other adhered items, so the pinstripes, decals, side 
moldings and other adhered items can be removed by the rubber erasing 
member without damaging the paint or other body parts of the vehicle. 
Like any standard rubber eraser, the rubber portion of the eraser member of 
the present invention vehicle adhesive remover will be used up in 
extensive usage. However, as the rubber portion of the rubber erasing 
member is worn out, the whole eraser unit 20 can be easily detached from 
the motor unit 12 and be replaced. Preferably the rubber material of the 
eraser member is 45 degree in hardness, and the disc shaped rubber member 
is three and half inches in diameter. 
The novel feature of the present invention portable remover is that, unlike 
the conventional tools designed for removing the pinstripes, decals, side 
moldings and other adhered items, the present invention remover does not 
remove the pinstripes, decals, side moldings and other adhered items by 
physically deteriorating, destroying or disintegrating them which often 
results in damaging the original paint or other body parts of the vehicle, 
but rather removes the pinstripes, decals, side moldings and other adhered 
items by using a high speed rotating rubber eraser to 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 will 
come off without damaging the paint or other body parts of the vehicle. 
The present invention vehicle adhesive remover can be used to remove 
anything adhered onto the vehicle by vehicle adhesives. As mentioned 
above, it can be used to remove pinstripes, decals, side moldings, etc. 
Sometimes when a side molding is pulled off a vehicle, it was held on by a 
two-sided adhesive. The present invention adhesive remover can also remove 
this type of two-sided adhesive effectively. In addition, the present 
invention vehicle adhesive remover can be used to remove other items 
adhered on various parts of the body of a vehicle, such as factory 
stickers adhered on certain parts of the vehicle, or price tickets and 
advertising slips adhered on the glass windows of the vehicle. 
The present invention adhesive remover has many advantages including: (a) 
it uses safe, convenient and harmless compressed air as its power source; 
(b) it is a light and small portable device; (c) it increases the speed of 
the process of removing various adhered items of a vehicle, yet reduces 
its difficulty; (d) it leaves no damage on the original paint or body part 
of the vehicles; and (e) the eraser unit is detachable so different sized 
eraser units may be used with a common motor unit.
