Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation-in-part of application
Ser. No. 10/819,248, filed Apr. 6, 2004. This application is
incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to sanders and, more
particularly, to random orbital sanders having multiple gripping
members, including a spaced vertical handle.
BACKGROUND OF THE INVENTION
[0003] Orbital sanders generally include a vertically orientated
housing having a handle at an axial end of the housing. Thus, the
handle is positioned above the orbital sanding element so that a
workman applies force directly onto the orbital sanding element.
These handles have various types of designs in order to accommodate
the workman's hand. Also, orbital sanders exist which include
handles which extend from the housing substantially perpendicular
to the orbital sander housing. These types of handles are in a
horizontal orientation. Thus, during use, for a significant period
of time, vibration can cause the user's hand to become fatigue.
Accordingly, it is desirable to have an orbital sander which
enables the user various gripping orientations to overcome the
shortcoming of the prior art.
[0004] The present invention provides the art with a orbital sander
that provides multiple gripping positions. The orbital sander
provides the user with a gripping surface spaced from the housing
and substantially parallel to the housing. Also, the present
invention provides the user with a gripping portion which surrounds
the housing to provide a 360 degree handle for various orientations
of the orbital sander. Also, the present invention provides the
user with a palm grip having a gel portion to reduce vibration in
the tool. The present invention also enables the user to utilize
both hands at various positions on the sander during operation.
SUMMARY OF THE INVENTION
[0005] According to a first aspect of the invention, an orbital
sander comprises a housing with an overall axial orientation. A
motor is positioned within the housing. An output is coupled with
the motor to drive the orbital sanding element. A power source is
coupled with the motor. An activation member is coupled with the
motor and the power source. The activation member energizes and
de-energizes the motor which, in turn, randomly rotates the output
and sanding element. A handle having an overall vertical
orientation is spaced from the housing. The housing ordinarily has
a cylindrical portion and a truncated conical portion adjacent the
cylindrical portion. A gripping member is positioned at the
intersection of the cylindrical portion and a truncated conical
portion. The gripping member surrounds a portion of the housing.
The gripping member that surrounds the housing is formed from an
elastomeric material providing comfort and feel for the user. Also,
a gripping member maybe positioned on an end of the housing
opposing the output. This gripping member may include a gel
portion.
[0006] According to a second aspect of the invention, an orbital
sander comprises a housing that has an overall axial orientation
with two ends. A motor is positioned within the housing. An output,
coupled with the motor, is positioned at one of the ends of the
housing to drive a sanding element. A power source is coupled with
the motor. An activation member is coupled with the motor and the
power source to energize and de-energize the motor which, in turn,
drives the output and the sanding element. A gripping member
surrounds the housing. The gripping member is positioned between
the ends of the housing. The gripping member is elastomeric to
provide comfort and feel. The gripping member is continuous 360
degrees around the housing. The gripping member has an annular
portion and an extending tail portion. The gripping member is
positioned on a truncated conical portion of the housing.
[0007] According to a third aspect of the present invention, an
orbital sander comprises a housing having an axial orientation with
a pair of ends. A motor is positioned within the housing. An
output, coupled with the motor, is positioned at one of the end to
drive a sanding element. A power source is coupled with the motor.
An activation member is coupled with the motor and the power source
to energize and de-energize the motor which, in turn, drives the
output and the sanding element. A plurality of gripping members are
coupled with the housing. At least one gripping member is spaced
from and positioned substantially parallel to the housing. The one
gripping member is a handle. The others of the gripping members are
on the housing. One of the gripping members surrounds a portion of
the housing. One of the gripping members is positioned on the end
of the housing opposing the output.
[0008] From the following detailed description taken in conjunction
with the accompanying drawings and subjoined claims, other objects
and advantages of the present invention will become apparent to
those skilled in the art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] The following description of the preferred embodiment(s) is
merely exemplary in nature and is in no way intended to limit the
invention, its application, or uses.
[0017] The following description of the preferred embodiment(s) is
merely exemplary in nature and is in no way intended to limit the
invention, its application, or uses.
[0018] Turning to the figures, an orbital sander is illustrated and
designated with the reference numeral 10. The orbital sander
includes a housing 12, a motor 14 positioned within the housing, an
output 16 driven by the motor 14, and a platen or carrier 18 that
is coupled to the output and oscillatingly driven. A sanding
element (not shown) is attached to the carrier 18. It should be
understood that a polishing or other similar element, other than a
sanding element, may be attached to carrier 18 and still be within
the scope of the invention.
[0019] A dust collection system 20 is coupled with the housing 12.
Also, a plurality of gripping members 22, 24, and 26 are coupled
with the housing. An AC power cord 28 is coupled with the housing
to provide power to the motor 14. An activation member 30 is
coupled with the housing to energize and de-energize the motor 14,
in turn, the output 16 which, in turn, rotates the carrier 18.
[0020] The housing 12 defines a central axis 13 and is normally
used in a vertical orientation. The housing 12 includes a
cylindrical portion 32 and a truncated conical portion 34
positioned on axis 13. The truncated conical portion 34 at its end
includes a skirt 36. The skirt 36 provides durability and protects
the work surface while sanding.
[0021] A housing gripping member 22 is positioned at the
intersection of the cylindrical portion 32 and the truncated
conical portion 34. The housing gripping member 22 includes an
annular portion comprising a gripping surface 40 and a tail surface
42. The gripping surface 40 surrounds the housing providing a 360
degree grip on the housing. The gripping surface 40 is positioned
at the other end of the truncated conical portion 34 wherein it
intersects the cylindrical portion 32. The tail surface 42 extends
from the gripping surface 40 towards the skirt 36. The housing
gripping member 22 is an elastomeric member and may be over molded
onto the housing 12. The elastomeric member provides a comfortable
grip as well as increased feel to the user.
[0022] The other end of the housing 12 includes an upper gripping
member 24. The extending end of the cylindrical portion 32 has a
teardrop shaped head 44 with the upper gripping member 24
positioned on top of the head 44. The upper gripping member 24 has
a teardrop shape and is formed from a gel material that forms an
upper gripping surface. Thus, the gel provides a top surface to
absorb vibration of the sander to increase the duration of use by
the user without fatigue.
[0023] Vertical axis 13 is located substantially centrally relative
to the sander housing 12 throughout its entire extent. That is,
axis 13 is centrally located with respect to all of upper gripping
member 24, cylindrical portion 32 and conical portion 34. Further,
as evident with reference to FIGS. 3a and 3c, upper gripping member
24 defines an outer perimeter such that a downward projection of
the outer perimeter defines a volume in which the housing 12 is
substantially disposed within throughout its entire extent. In
other words, the middle and lower parts of housing 12 do not extend
outwardly of upper gripping member 24 for any substantial
extent.
[0024] A handle gripping member 26 is spaced from the housing 12.
The handle gripping member 26 runs substantially parallel to the
housing 12, and has a vertical orientation enabling the user to
grip handle gripping member 26 to provide a different orientation
for the user's hands. The gripping orientations are illustrated in
FIGS. 2a-2e. Also, the user may use two hands when gripping the
handle gripping member 26 with another one of the gripping members
22 or 24.
[0025] The handle gripping member 26 is ordinarily formed with the
housing 12 to provide a clamshell type of housing member. The
handle gripping member 26 includes gripping surface 46 and 48 on
each of its sides. The gripping surfaces 46 and 48 are similar to
gripping surface 40, and made of an elastomeric material to provide
comfort and feel to the user.
[0026] An open space is formed between gripping surfaces 46, 48 and
housing 12 to allow for gripping of the gripping surfaces, with the
user's hand oriented in a substantially vertical orientation, as
explained below.
[0027] During operation, a user may grip the orbital sander at
gripping member 22, 24 or 26. This allows the user to vary his hand
positions to reduce fatigue during prolonged operation. Also, the
user may use a plurality of the gripping members at one time. The
user may use grips 22 and 26, 24 and 26, or 22 and 24 at one time
to add increased control to the sander during operation.
[0028] Although as discussed above, the sander may be gripped with
two hands utilizing various combinations of grips 22, 24 and 26,
the preferred overall configurations and weight allow for the
sander to be operated by the user with one hand by solely gripping
upper grip 24. As shown in FIG. 2a, in this sole gripping position,
the user's hand may extend substantially over the entire extent of
the sander housing 12. In such a configuration, the user's palm
rests substantially in a horizontal plane. One advantage provided
by this invention is that in addition to allowing for such
overhanded gripping at the top of the sander, the user also can
grip the sander with his second hand gripping spaced handle 26. In
particular, as shown in FIG. 2b, the user grips gripping surfaces
46 and 48 of handle 26 such that the palm of the second hand is
disposed substantially vertically and therefore perpendicular to
the palm of the first hand, to provide increased control during
operation.
[0029] With reference to FIG. 3a, preferred dimensions in
millimeters for the sander are shown. In a preferred embodiment,
the weight of the orbital sander may be approximately 3.5 pounds.
As shown, the handle 26 need not be disposed precisely
perpendicular to the gripping surface of upper grip 24, that is, it
need not be disposed precisely vertical. For example, in one
preferred embodiment handle 26 and thus gripping surfaces 46 and 48
may be disposed substantially vertically at 103.46.degree. to the
horizontal gripping surface of upper grip 24, and thus at an angle
of 13.46.degree. to the vertical axis of housing 12. Prefereably,
this angle may be varied within a range of 5.degree..
[0030] FIGS. 4a and 4b show a second embodiment of the invention,
where the carrier 18, and consequently the sanding element (not
shown), is rectangular shaped. The orbital sander shown in FIGS. 4a
and 4b is a 1/4 sheet sander, with the approximate dimension of the
sander shown in millimeters.
[0031] The description of the invention is merely exemplary in
nature and, thus, variations that do not depart from the gist of
the invention are intended to be within the scope of the invention.
Such variations are not to be regarded as a departure from the
spirit and scope of the invention.
