This invention relates to personal care means, devices and apparatuses. More particularly, this invention relates to means, devices and apparatus for manicure and/or pedicure. More specifically, although of course not solely limited thereto, this invention relates to nail care apparatus.
In recent years, it has been noted that people are paying increasing attention to the beauty and care of their nails. As a result, manicure and pedicure products and services are becoming more and more visible in the personal care and beauty business or industries. To decorate finger or toe nails, many pedicure or manicure products such as nail polish, nail varnish, nail colours or nail gels are readily available.
Many nail care substances are in liquid, fluid or gel form which are to be applied in layers to achieve optimal results. Usually, optimal results can only be obtained if subsequent layers are applied after the previous layers have been thoroughly dried. As a result, a complete manicure or pedicure process can take a considerably long time. Most known fluid based nail care substances contain volatile solvents which have strong scent or odours and may be adverse to health if subject to prolonged exposure.
Therefore, it is highly desirable if there can be provided means, devices or apparatus which alleviate the above problems or potential hazards as well as shortening the time for optimal manicure or pedicure. While apparatus for drying decorated finger nails are known, their functions are limited to drying and do not provide sufficient utility or sufficiently alleviate the aforesaid problems. Furthermore, in using such drying apparatus, a user has to transfer his/her hand or foot from a support surface on which the nail caring substances were applied to the drying apparatus. This can be a nuisance if several layers of nail caring substances are to be applied. Accordingly, it would be highly desirable if improved means, devices or apparatus for nail care can be provided.
Accordingly, it is an object of the present invention to provide improved nail care means, devices or apparatus. More specifically, although of course not limited thereto, it is an object of the present invention to provide nail caring apparatus which alleviates at least some of the problems associated with conventional nail care methods or apparatus. Of course, the above objectives are to be read disjunctively with the minimum of providing the public with a useful choice.

Preferred embodiments of the present invention will be explained in further detail below by way of examples and with reference to the accompanying drawings, in which:
a is a top plan view of the apparatus of
Referring firstly to FIGS. 1 to 4, the nail care apparatus 100 includes a first housing 110, a second housing 120 and a support housing 130 interconnecting the first housing 110 and the second housing 120. The first housing 110 is generally made of a heat resistance and insulating material such as hard plastics and includes a hollow compartment 111. Nail curing means such as a conventional heater assembly 112, an ultra-violet radiation means 113 or other appropriate curing means, whether in combination or as alternatives, are accommodated in the hollow compartment 111 of the first housing 110. A rotary blower assembly 114 is also mounted inside the first housing 110 to supply hot air to speed up drying of the nail care substances.
The first housing 110 includes a top portion 115 and a bottom portion 116 between which the hollow compartment is formed. The bottom portion 116 of the first housing 110 includes a transparent window 117 for passage of the ultra-violet radiation generated by the ultra-violet source 113 and an air-window 118 for transmitting the heat or hot air generated by the heater assembly 112 towards the hand-or-foot receptacle 121 on the second housing 120.
The second housing 120 generally defines the base of the apparatus 100 and provides support to the entire apparatus 100. In this preferred embodiment, the second housing 120 is also made of a heat resistant material such as hard plastics and includes a hollow compartment inside which there is mounted a propeller fan 122. A volatile nail caring substances removal means 123, which can be, for example, absorption means, adsorption means or other appropriate means such as a de-odourizing means, a de-odourizing filter or other appropriate devices or arrangements suitable for removing smell, odour or volatile substances is disposed adjacent to the propeller fan 122. The volatile nail caring substances removing means is placed downstream to the propeller fan in this example. Of course, this volatile nail caring substances removal means can be placed upstream, downstream or both upstream and downstream of the propeller fan 122. The top portion 124 of the second housing 120 (or the base) which is facing or opposite the first housing 110 includes a perforated surface so that air in the space between the first 110 and the second housing 120 can enter the second housing 120 through the perforations and by the suction caused by the propeller fan 122.
The support housing 130 interconnects the first housing 110 and the second housing 120 so that the first housing 110 is elevated above the second housing 120. The space between the first housing 110 and the second housing 120 is for receiving the hand or the foot of a user to be explained below. The support housing 130 also includes an extension means so that the distance of separation between the first housing 110 and the second housing 120 can be adjusted and maintained. The extension means includes a telescopic-type structure with an internal helical spring 131 to provide spring bias so that when the catching mechanism is released while the extension means is under spring urge, the extension means will extend the support housing 13 upwards, thereby increasing the separation between the first housing 110 and the second housing 120.
A switching actuator 141 is mounted on the first housing 110 for actuating and de-actuating the nail curing means (including the heater assembly 112, the ultra-violet radiation source 113 and the blower 114). The switching actuator 141 includes a shaft which spans transversely across the support housing 130 and is controllable by a switching lever 142. The switching lever 142 includes a plurality of salient or protruding actuation contacts which are positioned and adapted for mechanically coupling with the switching actuator 141 at various positions of the support housing 130, including the unextended and various pre-determined extended positions of the support housing.
Referring to
Turning to an exemplary use of this apparatus. After application of nail caring substances onto a user's nails has been completed, the first housing 110 can be tilted upwards to provide more space so that a user can place his hand or foot onto the hand-or-foot receptacle 121 while alleviating the risk of the newly treated or painted nails from being scratched by the first housing 110. Alternatively, a user can also apply nail caring substances with his hand or foot placed on the hand-or-foot receptacle 121 while the first housing 110 is tilted upwards to save the trouble of having to move the hand or foot from where the nail curing substances were applied to the hand-or-foot receptacle 121. Of course, the hand-or-foot receptacle 121 may also include an ergonomically shaped surface for receiving the palm or the plantar surface of the foot for enhanced comfort.
When a hand or foot having been applied with nail caring substances is placed on the hand-or-foot receptacle 121, the first housing 110 is restored to the configuration of FIGS. 2 or 3, depending on the size of the hand or foot. Next, the nail curing means will be activated so that the treated nails will be subject to the appropriate curing treatments such as heating, ultra-violet irradiation or a combination of both. The blower 114 may also be activated to increase the drying speed where appropriate. When the curing process is taking place, the propeller fan 122 will operate as a first air-moving means to draw air in the vicinity of the nails towards the de-odouring filters to reduce or alleviate the smell, odour or the volatile substances which may be hazardous to health.
In a slightly modified version of this first preferred embodiment, the first housing 110 includes a perforated top surface 119. This perforated surface 119 is disposed at the top of the first housing 110 and is distal or distant from the second housing 120. This perforated surface 119 provides a path for air above it to move into the hollow compartment 111 for subsequent removal of the residual nail caring substances by absorption means disposed in the second housing described below. In addition, this perforated surface 115 is adapted for receiving the palm of a user and is ergonomically shaped for this purpose.
Turning now to an exemplary use of this slightly modified version of the first preferred embodiment, the top perforated surface 115 of the first housing is optimally designed to receive the palm of a user to facilitate comfortable and convenient application of nail caring substances such as, for example, nail coating or polishes, nail varnish or nail gels. The perforated surface 115 is ergonomically designed and curved for enhanced comfort while the nails are being attended to. To alleviate problems with smell or odour emanating from the volatile nail caring substances, the nail, the air blower 114 and the propeller 122 will be actuated during application of the volatile nail caring substances to draw air in the vicinity of the perforated surface 115 towards the filter 123, thereby removing smell, odour or the residual volatile nail caring substances.
Hence, in the present example of the slightly modified version, the apparatus includes first air-moving means comprising the propeller fan 122 for moving air from the hand-and-foot receptacle to the de-odourizing means arid second air-moving means comprising the air blower 114 for moving scented air in the vicinity of the top perforated surface 115 towards the deodorizing means.
In the following, numeral reference to the figures has the following convention where appropriate and unless otherwise stated. The first digit refers to the embodiment number and the last two digits refer to the parts as designated by the second and third digits of the numerals used in the first preferred embodiment even if the numerals are not further described or repeated in the specification for brevity.
Referring to FIGS. 5 to 8, there is shown a second preferred embodiment of a nail care apparatus of the present invention. The apparatus 200 includes a first housing 210, a second housing 220 and a support housing 230 interconnecting the first housing and the second housing. Similar to the first preferred embodiment, nail curing means such as a conventional heater assembly 212, an ultra-violet radiation means 213 or other appropriate curing means, whether in combination or as alternatives, are mounted in the hollow compartment 211 of the first housing 210. Similarly, a rotary blower assembly 214 is also mounted inside the hollow compartment 211. Unlike the first preferred embodiment, the rotary blower assembly is functioning both as the first air-moving means for moving air from the hand-and-foot receptacle and the second air-moving means for moving scented air in the vicinity of the top perforated surface 215 of the first housing 210 towards the de-odourizing means. The dual functionality of this rotary blower is made possible by configuring the hollow compartment into two alternative air-channels or air-passage ways and through the control of a two-way valve 250.
Unlike the first preferred embodiment, while the second housing 220 functions as the supporting base of the apparatus 200, it does not provide a perforated surface or a passageway for air to move from the hand-and-foot receptacle 221 towards the deodurizing means 253. Instead, a perforated surface, which is in communication with an air channel formed inside the first housing 210, and the support housing 230 is formed on the surface of the support housing adjacent the hand-and-foot receptacle 221. By controlling the two-way valve 251, two alternative air-passage paths, namely, the first air-passage path and the second air-passage path, are formed.
The first air-passage path defines generally the direction of air-flow while the apparatus is configured as means for removing volatile nail caring substances when the nails are being treated and with the palm resting on the top perforated surface 219. During this operation mode, the two-way valve 251 is moved anti-clockwisely until the second air-passage path is closed. In this operating mode, the rotary blower operates as the second air-moving means and the low-pressure region generated by the air-blower will cause air in the vicinity of the top perforated surface 219 to move towards the hollow compartment 211 through the de-odourizing filter 253 and exhaust through the air-window 218. Alternatively, and as shown in
Referring to FIGS. 9 to 11, there is shown a third preferred embodiment of a nail care apparatus 300 of the present invention. The apparatus 300 is generally identical to the apparatus 200 of the second preferred embodiment except that the hollow compartment and the air channels are configured so that a common volatile nail caring substances removal means, for example, a de-odorising filter 354, is installed along a common path shared by the first and the second alternative air-passage paths through the control of the two-way valve 351. More specifically, a buffering compartment 355 is formed inside the hollow compartment 311. The buffering compartment 355 includes first 356 and second 357 alternative inlets which are respectively connected to the first and the second air-passage channels and at the upstream ends of the buffering compartment 355. The common de-odourizing filter 354 is disposed at the outlet or the downstream end of the buffering compartment. By selectively switching the opening or closing of the two-way valve 351, the de-odourizing filter 354 will function as a de-odourizing filter for the respective air-passage channels, thereby simplifying the structure of the apparatus as well as reducing the number of individual de-odourizing filters required.

On the other hand, when the nail care apparatus 300 is operated as means for removing odour during application of the volatile nail caring substances onto nails as shown in
Referring to
The first housing 410 includes a hollow compartment 411 inside which there are mounted a rotary air blower 414, a heater assembly 412 and an ultra-violet radiation source 413. An air-window 418 and a transparent window 417 are respectively provided for passage of hot air emanating from the heater assembly and for passage of the curing radiation emanating from the ultra-violet or other appropriate curing sources.
The second housing 420 includes a first air-moving means and comprises a propeller fan 432 for moving air from the hand-and-foot receptacle 421 to a de-odourizing means disposed downstream of the propeller fan 422.
The support housing 430 includes a hollow chamber 434 and an extension means for extending the support housing so as to change the elevation of the first housing above the second housing. Unlike the first preferred embodiment, a perforated surface 433 is formed on the surface of the support housing opposite the hand-and-foot receptacle to allow passage of air in the vicinity of the hand-and-foot receptacle into the support housing. The air channel formed inside the hollow compartment of the support housing provides a path for air streams originating from the hand-and-foot receptacle to move towards the upstream end of the propeller fan for further transmission towards the filtering or de-odourizing means and then for subsequent release from the apparatus.
In this preferred embodiment, the top surface 424 of the second housing 420 is non-perforated so that motion of the propeller fan will generate a low-pressure region within the second housing to provide adequate suction to attract air in the vicinity of the perforated surface of the support housing. Similar to other preferred embodiments, the first housing can also be tilted relative to the support housing and can be latched at several pre-determined positions for more convenient placing of a hand or foot onto the hand-and-foot receptacle.
FIGS. 17 to 20 show a fifth preferred embodiment of a nail care apparatus 500 of the present invention. The apparatus includes a first housing 510, a second housing 520 and a support housing 530. The first housing 510 is substantially identical to that of the first preferred embodiment. The second housing 520 is substantial identical to that of the second housing. The support housing 530 is generally the same as that of the fourth preferred embodiment except that the de-odourizing means 554 and the air-moving means 556 are both disposed within the support housing 530 and are configured to suck and filter the air in the vicinity of the hand-and-foot receptacle through the perforated surface and then to release the filtered air at the back of the support housing.
