Description
(a) TECHNICAL FIELD OF THE INVENTION
[0001] The present invention generally relates to a rotary disc
structure of a polishing/grinding machine, and more particularly to
a rotary disc structure of a polishing/grinding machine that
carries out efficient polishing and waxing operations on an
automobile body, without causing scratching of the automobile
body.
(b) DESCRIPTION OF THE PRIOR ART
[0002] Automobiles are commonly used transportation in the modern
society. A lot of families own automobiles. Generally speaking, the
automobiles are expensive commodity and thus, in addition to
transportation, the automobiles are also a luxury of indication of
social position for rich people. Thus, maintenances of automobiles
are sometimes very expensive and elaborate. For example, the paint
of an automobile must be periodically cleaned and properly waxed in
order to eliminate attachment of contaminants to the automobile
body and also to protect the paint from being corroded by acidic
rainwater and to make the paint shinny and glittering. Generally,
the commonly adopted way of waxing an automobile is to first
attaching wax for automobiles to a sponge and then the sponge is
fast rotated on the automobile body to wax the automobile body.
With the progress of technology and science, electrical polishing
devices are now available, and the sponge for waxing can be
attached to a rotary dis, which is in turn coupled to an electric
motor so that the electrical motor may drive the sponge to fast
rotate thereby achieving an effect of fast waxing on the paint of
the automobile. In addition, the electric polishing device is also
operable for polishing and removing scratching of the automobile
paint.
[0003] However, the electric polishing devices that are currently
known are often configured with a rotary disc that is generally a
circular flat surface. Compared to hand waxing operation, the
electric polishing device shows features of fast waxing and
polishing for scratching removal, but use of such an electric
polishing device is not convenient. The rotary disc is coupled,
with a center thereof, to an electric motor and thus, the part of
the rotary disc that is relatively distant from the center of
rotation would carry a relative large torque. In other words, when
the rotary disc rotates, a radially outer portion of the rotary
disc would apply a relative large force to the automobile body.
Consequently, the operation of waxing or scratching removal for an
automobile body is generally conducted with the radially outer part
of the rotary disc. However, since the surface of an automobile
body often include curved parts and these parts make the operation
of waxing or scratching removal of the automobile body inconvenient
with the rotary disc that is generally of a flat surface.
Particularly, the outer circumferential part of the rotary disc
often undesirably causes scratching of the automobile paint.
SUMMARY OF THE INVENTION
[0004] The primary objective of the present invention is to achieve
easy and efficient automobile body polishing and scratching removal
or waxing without causing undesired scratching on the automobile
body by means of an arrangement of a slope section.
[0005] Another objective of the present invention is to allow a
cleansing member, such as a sponge, to be coupled to a rotary disc
by means of an arrangement of a coupling section.
[0006] A further objective of the present invention is to achieve
an effect of efficiency and effort saving by coupling a rotary disc
to an electric motor by means of an arrangement of a coupling
section.
[0007] To achieve the above objectives, the present invention
provides a structure that comprises a disc, and the disc is
configured with a flat section and at least one slope section
located on an outer side of the flat section. The flat section is
provided with at least one coupling section, and the coupling
section can be used to couple a cleansing member, such as sponge,
to the disc. Further, the disc is provided on a side thereof that
is distant from the coupling section with a coupling member. The
coupling member can be coupled to an electric motor. As such, with
an attempt to wax or polish an automobile body, a user attaches wax
to the cleansing member and activates the electric motor to
uniformly coat the wax on the automobile body. However, during the
rotation of the disc, the slope section that is located on the
outer side may apply a relatively large operation force to the
automobile body so that polishing or waxing the automobile body
with the slope section would allow the operation to be conducted on
a curved part of the automobile body, making the user more
convenient and efficient, and further, the arrangement of the
inclination prevents an edge of the disc from scratching and
damaging the automobile body, so as to provide practical
improvement in respect of utilization thereof.
[0008] With the above techniques, the problems of the prior art
rotary disc of an electrical polishing device that the use is
inconvenient and may readily cause scratching and damage to an
automobile body can be overcome to achieve the practical
improvement in respect of utilization of this invention as
mentioned above.
[0009] The foregoing objectives and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the
claims should be read in conjunction with the accompanying

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] The following descriptions are exemplary embodiments only,
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0019] Referring to FIGS. 1-3, which are respectively a perspective
view showing a preferred embodiment of the present invention, a
cross-sectional view of the preferred embodiment of the present
invention, and another cross-sectional view of the preferred
embodiment of the present invention, it can be clearly seen from
these drawings that the present invention comprises:
[0020] a disc 1, wherein the disc 1 is configured with a flat
section 11 and at least one slope section 12 located on an outer
side of the flat section 11;
[0021] at least one coupling section 13 provided on the flat
section 11, wherein the coupling section 13 comprises for example a
piece of hook-and-loop fastener for coupling with at least one
cleansing member 2, wherein the cleansing member 2 is for example a
sponge; and
[0022] a coupling member 14 provided on a side of the disc 1 that
is distant from the coupling section 13, wherein the coupling
member 14 is formed with a through-hole section 141 and the
through-hole section 141 is formed with at least one threaded
section 142 for coupling with an electric motor 3, wherein the
coupling member 14 is formed, on a side thereof that is distant
from the through-hole section 141, with at least one fixing section
143.
[0023] Referring to FIGS. 1-4, which are respectively a perspective
view showing a preferred embodiment of the present invention, a
cross-sectional view of the preferred embodiment of the present
invention, another cross-sectional view of the preferred embodiment
of the present invention, and a schematic view illustrating an
operation of use of the preferred embodiment of the present
invention, it can be clearly seen from these drawings that with an
attempt to wax or polish an automobile body 4, a user may couple
the cleansing member 2 to the coupling section 13 and screw the
coupling member 14, by means of the threaded section 142 formed in
the through-hole section 141, to the electric motor 3 so as to
couple the disc 1 and the electric motor 3 together. The fixing
section 143 provided on the coupling member 14 allows the user to
apply a wrench to easily couple or remove the coupling member 14 to
or from the electric motor 3. Further, the user may attach wax to
the cleansing member 2 and then activate the electric motor 3 to
allow the electric motor 3 to drive the cleansing member 2 to
rotate so that the cleansing member 2 may coat the wax uniformly on
the automobile body 4. However, since, during the rotation of the
disc 1, the slope section 12 that is spaced from a center of the
disc 1 by a distance greater than a distance of a part or the
entirety of the flat section 11 from the center the disc 1 provides
a torque larger than that provided by the flat section and thus
would apply a relatively large operation force to the automobile
body 4. Thus, the operation of waxing or polishing for scratching
removal of the automobile body 4 can be conducted in a more
efficient way by means of the slope section 12. It is more
important that the slope section 12 is arranged as being inclined
with respect to the flat section 11 and can thus be positioned more
closely and tightly on a curved part of the automobile body 4.
Further, in use, the inclined arrangement of the slope section 12
allows an outer circumferential edge of the disc 1 not to easily
contact the automobile body 4, so that undesired scratching on the
automobile body 4 by the edge of the disc 1 can be prevented.
[0024] Further, the disc 1 is integrally formed as a unitary
structure and thus possesses the advantages of efficient
fabrication and cost saving.
[0025] Referring to FIG. 5, which is a cross-sectional view showing
another embodiment of the present invention, it can be clearly seen
from the drawing that a disc 1a is configured with a flat section
11a and at least one slope section 12a arranged at an outer side of
the flat section 11a and the slope section 12a is provided with at
least one coupling section 13a for coupling with a cleansing member
2a. The disc 1a is formed, on a side thereof that is distant from
the coupling section 13a, with a coupling member 14a that is formed
with a through-hole section 141a comprising a threaded section 142a
for coupling the disc 1a to an electric motor. Further, the
coupling member 14a is provided with a fixing section 143a that
allows a user to use a wrench to easily couple or remove the
coupling member 14a to or from the electric motor. A difference of
the instant embodiment from the previous embodiment is that the
coupling section 13a is provided on the slope section 12a, rather
than the flat section 11a so that the cleansing member 2a can be
more closely positioned on the slope section 12a to achieve the
purpose of preventing a circumferential edge of the disc 1a from
scratching the automobile body.
[0026] Referring to FIGS. 6 and 7, which are respectively a
cross-sectional view showing a further embodiment of the present
invention and a schematic view illustrating an operation of use of
said further embodiment of the present invention, it can be clearly
seen from the drawings that a disc 1b is configured with a flat
section 11b and at least one slope section 12b arranged at an outer
side of the flat section 11b, wherein the flat section 11b and the
slope section 12b are provided with at least one coupling section
13b. The coupling section 13b is provided for coupling with at
least one cleansing member 2b so that a user may use the electric
motor 3b to drive a cleansing member 2b that is coupled to the disc
1b to conduct waxing or polishing for scratching removal on an
automobile body 4b. A difference of the instant embodiment from the
previous embodiments is that the coupling section 13b is provided
on both the slope section 12b and the flat section 11b so that the
cleansing member 2b can be more closely positioned on both the
slope section 12b and the flat section 11b to prevent the cleansing
member 2b from easily detaching from the disc 1b during a waxing
operation and thus, achieving the purpose of preventing the disc 1b
from scratching and damaging the automobile body 4b.
[0027] Reference is now made to all the drawings. The present
invention, when put into use, provides the following advantages
over the prior art devices:
[0028] (1) The arrangement of the slope section 12 allows for easy
and efficient polishing and waxing an automobile body 4 without
causing undesired scratching or damage to the automobile body
4.
[0029] (2) The arrangement of the coupling section 13 allows a
cleansing member 2, such as sponge, to be coupled to the disc
1.
[0030] (3) The arrangement of the coupling member 14 allows
coupling of the disc 1 to an electric motor 3 to be conducted with
an effect of being efficient and effort saving.
[0031] (4) The arrangement of the fixing section 143 allows the
user to use a wrench to easily couple or remove the coupling member
14 to or from an electric motor 3.
[0032] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0033] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claims, it
is not intended to be limited to the details above, since it will
be understood that various omissions, modifications, substitutions
and changes in the forms and details of the device illustrated and
in its operation can be made by those skilled in the art without
departing in any way from the claims of the present invention.
