Description
[0001] The present invention relates to electrical nail polishing
apparatus, and more particularly to an electrical nail polishing
apparatus comprising a motorised electrical nail polishing device
provided with a plurality of inter-changeable heads to impart at
least one of a filing or abrasion effect to the surface of a nail,
a buffing effect to the surface of a nail, or a polishing effect to
the surface of a nail.
[0002] Electrical motorised nail polishing devices with
interchangeable heads that can impart different effects in use are
known. In operation a user would typically use the device as part
of a three-stage process, firstly, the user would connect the
filing head. The user would then activate the device and the motor
causes the oscillating linear motion of the filing head and the
user would apply the filing surface of the head to a finger nail or
a toe nail to file the nail as required. The user would then
deactivate the head and exchange the filing head for a separate
buffing head. Similarly the user would then activate the device to
cause oscillating linear motion of the buffing head and would apply
this to the finger nail or toe nail as required. The user would
then deactivate the head and exchange the buffing head for a
separate polishing head. Lastly the user would then activate the
device to cause oscillating linear motion of the polishing head and
would apply this to the finger nail or toe nail as required and
then deactivate the device. These known devices provide the
oscillating linear motion at a high frequency to provide efficiency
of use in filing/buffering/polishing the user's nail, one potential
drawback is that due to the number of head changing operations
required a user may inadvertently expose their nails to inaccurate
filing/buffering/polishing should they incorrectly perform the head
changing operation. The present invention seeks to address this and
other drawbacks.
[0003] According to a first aspect of the present invention there
is provided an electrical nail polishing apparatus comprising an
electrical nail polishing device and a plurality of releasably
connectable heads, wherein the electrical nail polishing device
comprises: a main body housing accommodating a power source
electrically connected to a motor with a rotating shaft connected
to a transmission gearing mechanism connected to a proximal end of
a drive shaft, the transmission gearing mechanism is configured to
convert the rotational motion of the rotating shaft into
oscillating longitudinal movement of the drive shaft, the remote
end of the drive shaft extends beyond a tip end of the housing, the
tip end of the housing is configured to extend away from the main
body housing by at least 2 mm to provide a face surface with a flat
side at or adjacent a diameter line of the main body housing with
the ends of the flat side being joined by a curved side having one
or more radii;
and wherein the releasably connectable head comprises: a landing
plate which has one side provided with a nail contact material and
the other side of the landing plate is provided with a head housing
inboard of the periphery of the landing plate, the head housing is
closed at a top end and open at a base end and is provided with a
cavity that accepts the remote end of the drive shaft and the tip
end of the housing therein and wherein the cavity corresponds to
the shape of the tip end, within the cavity a socket is provided
that is configured to releasably connect to the drive shaft, and
wherein a landing plane is provided at the base end of the landing
plate by the cavity end of the head housing being located at least
2 mm inboard from the base end of the landing plate.
[0004] The present invention offers numerous advantages over the
prior art apparatuses, a principal advantage is the assurance that
the releasably connectable head can only be attached to the drive
shaft of the polishing device in a single orientation. The single
orientation is facilitated by the landing plane of the landing
plate which extends by at least 2 mm from the head housing at the
base of the landing plate. To correctly orientate and connect the
releasably connectable head to the polishing device a user will
push the head such that the cavity swallows the remote end of the
drive shaft to surround the tip end of the device housing such that
the landing plane is adjacent to the flat side of the of the tip
end which in turn will permit the cavity of the head housing to
accommodate the tip by virtue of it corresponding shape. In
contrast, if a user did not correctly orientate the releasably
connectable head to the tip end of the polishing device prior to
connection the landing plane will abut a part of the tip end of the
device and prevent connection therebetween.
[0005] A further advantage provided by the landing plane is the
provision of a greater surface area of the landing plate thus
increasing the surface area of the nail contact material which may
allow for improved nail polishing results for the user.
[0006] A yet further advantage provided by the landing plane is
that it permits a greater proportion of the tip to be surrounded by
the head which may afford improved stability during use when the
user is imparting perpendicular force on the connection between the
releasably connectable head and the polishing device during the act
of polishing finger nail or toe nail.
[0007] Preferably the landing plane extends beyond the cavity end
of the head housing from between 2 mm-10 mm, and more preferably
extends from between 2 mm-7 mm, and even more preferably extends
from between 3 mm-6 mm, and most preferably extends by 5 mm.
[0008] The head housing of the releasably connectable head is
provided with a cavity that accepts the remote end of the drive
shaft and the tip end of the housing therein and corresponds to the
shape of the tip end wherein the clearance between an interior of
the cavity and the tip end of the polishing device is between 1
mm-5 mm, and preferably between 1 mm-3 mm, and most preferably
between 1 mm-2 mm.
[0009] The landing plate is preferably curved at its top end to

may be provided with a collar, said collar being configured for
releasable connection with the socket of the head housing, said
releasable connection providing an audible click which may provide
the user with confirmation that the correct connection has been
made. Alternatively the drive shaft may be provided with a notch or
the like removed therefrom and the socket of the head housing is
configured for releasable connection with the notch, said
releasable connection providing an audible click which may provide
the user with confirmation that the correct connection has been
made.

from the main body housing by between 2 mm-10 mm, and more
preferably extends by between 2 mm-7 mm, and even more preferably
extends by between 3 mm-6 mm, and most preferably extends by 6
mm.
[0013] An intermediate housing may be provided between the tip end
and the main body housing, and where the intermediate housing is
provided, the tip end extends away from the intermediate housing
rather than the main body housing. The intermediate housing may be
provided with a tapered surface and may be provided with a cap
engagement means.
[0014] A cap may be provided with a cavity of sufficient volume to
accommodate a releasably connectable head connected to the drive
shaft of the device therein and said cap may be sized engage with
the cap engagement means of the intermediate housing to releasably
secure the cap to the device.
[0015] The device may be provided with a sliding switch to permit a
user to select the operating parameters of the apparatus. The
sliding switch may have two positions defining "on" and "off".
Preferably the sliding switch is provided with more than two
