[0030] Referring to FIGS. 1&2, an electrical nail polishing device 1 is shown. The device 1 has a main body housing 2 which is sized to accommodate a power source (not shown) such as one or more batteries, the power source is electrically connected to a motor (not shown). The motor is provided with a rotating shaft (not shown) connected to a transmission gearing mechanism (not shown) which is configured to drive a proximal end of a drive shaft 3. The transmission gearing mechanism is configured, in use, to convert the rotational motion of the rotating shaft into oscillating longitudinal movement of the drive shaft 3, the remote end 4 of the drive shaft 3 extends beyond a tip end 5 of the housing 2, the tip end 5 of the housing is configured to extend away from the main body housing 2 by at least 2 mm to provide a face surface 6 with a flat side 7 at or adjacent a diameter line of the main body housing 2 with the ends of the flat side 7 being joined by a curved side 8 having one or more radii. An intermediate housing 9 is provided between the tip end 5 and the main body housing 2.

[0031] The tip end 5 of the housing of the device preferably extends from the intermediate housing 9 by between 2 mm-10 mm, and in FIG. 2 the tip end 5 is shown as extending by about 6 mm.

[0032] The intermediate housing 9 is provided with a tapered surface 10 and is shown with a cap engagement means 11 at the border with the main body housing. A cap (not shown) may be provided sized to engage with the cap engagement means 11 of the intermediate housing 9 to releasably secure the cap to the device 1.

[0033] A sliding switch 12 is provided to permit a user to select the operating parameters of the device 1, the sliding switch 12 may have two positions defining on and off but preferably is provided with more than two positions, a first position defining off and other positions being on at differing speeds to allow a user to define the preferred frequency of movement for the particular action they wish to impart to their nail, such as filing, buffering or polishing, in use.

[0034] Turning to FIGS. 6&7, a releasably connectable head 13 is illustrated. The head 13 has a landing plate 14 which has one side provided with a nail contact material 15 and the other side of the landing plate 14 is provided with a head housing 16 inboard of the periphery of the landing plate 17. The head housing 16 is closed at a top end 18 and open at a base end 19 and is provided with a cavity (not shown) that accepts the remote end of the drive shaft 4 tip end 5 of the housing therein and the cavity corresponds to the shape of the tip end 5. Within the cavity a socket (not shown) is provided that is configured to releasably connect to the remote end of the drive shaft 4.

[0035] A landing plane 20 is provided at the base end 19 of the landing plate 14 by the cavity end of the head housing 16 being located at least 2 mm inboard from the base end 19 of the landing plate 14.

[0036] The landing plane 20 extends beyond the cavity end of the head housing from between 2 mm-10 mm, and is shown in FIGS. 6&7 to extend by about 5 mm.

[0037] The cavity accepts the remote end of the drive shaft 4 and the tip end 5 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 5 is between 1 mm-5 mm, and shown in FIGS. 3-5 as between about 1 mm-2 mm.

[0038] The landing plate 14 is curved at its top end 18 to facilitate more precise nail polishing.

[0039] The nail contact material 15 completely fills the surface area of the landing plate 14. The nail contact material 15 may be a material that is suitable for imparting one of the following effects, namely; filing; buffing; or polishing.

[0040] Turning to FIGS. 3-5 an electrical nail polishing apparatus 21 is shown comprising an electrical nail polishing device 1 with a releasably connectable head 13 releasably connected thereto. As can be seen, the releasably connectable head 13 can only be attached to the remote end of the drive shaft 4 of the polishing device 2 in a single orientation. The single orientation is facilitated by the landing plane 20 of the landing plate 14 which extends by at least 2 mm from the head housing 16 at the base 19 of the landing plate. To correctly orientate and connect the releasably connectable head 13 to the polishing device 2 a user will push the head 13 such that the cavity swallows the drive shaft 4 and surrounds the tip end 5 of the device housing such that the landing plane 20 is adjacent to the flat side 7 of the of the tip end 5 which in turn will permit the cavity to accommodate the tip 5 by virtue of its corresponding shape. In contrast, if a user did not correctly orientate the releasably connectable head 13 to the tip end 5 of the polishing device prior to connection the landing plane 20 will abut a part of the tip end 5 of the device and prevent connection therebetween.
