(10) As used herein, the term slidably attached refers to means for enabling the shield to slide in a direction that either enlarges or reduces the size of the opening to the irradiation chamber in the device that is available to the user for insertion of an attendant hand or foot requiring nail gel curing.
(11) With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new fingernail gel curing device embodying the principles and concepts of the present invention and generally designated by the reference numeral 1 will be described. The device 1 comprises an outer housing 16, a base 14, and a dome 19 as shown in certain of FIGS. 1 through 6. The outer housing, base and dome are attached to one another and configured such that they define an irradiation chamber 8 within the device and below the apex of the dome. They also define a space between the outer housing 16 and the dome 19 in which the electronics, including the LEDs, timers, and power controls are located. They are attached to one another and configured such that the dome 19 and irradiation chamber 8 are within the outer housing. FIG. 1 is a perspective view taken from the back lower left of an exemplary embodiment of an LED-equipped fingernail gel curing device of the present invention having a shield 6 that reduces the level of extraneous secondary UV light to which a user is exposed outside the confines of the fingernail gel curing device. The shield is not visible if FIG. 1 but is visible in FIG. 2. In the embodiment shown in FIG. 1, a detachable tray 2 is magnetically affixed at the base of the device in a substantially horizontal manner in relation to the base. The rear of the device' outer housing has a viewing window 3 for the timer and three buttons 4 for preset times of irradiation. The device also has an electrical connection 5 for providing power to the device. The tray has a series of openings 12 that align with corresponding openings 13 in the base of the device, to which the tray is removably attached, to allow air to enter the internal space as defined by the outer housing, base and dome through the openings and exit through grillwork located in the apex of the dome. This air moving through the device enables heat generated by the LEDs or other electronics during operation to be removed from the device. The tray also has protuberances (or feet) 17 attached to its lower face to permit entry of outside air from underneath the device through the openings into the internal space of the device where the electronics are housed.
(12) FIG. 2 is a perspective view taken from the front upper right of the exemplary embodiment shown in FIG. 1. FIG. 2 depicts a slidable shield 6 set in the open position above the opening 7 to the irradiation chamber 8 in the embodiment shown. Two LEDs 9 of a plurality of such are shown inset into the side walls 10 of the dome comprising the irradiation chamber.
(13) FIG. 3 is a frontal view of the exemplary embodiment shown in FIG. 1. FIG. 3 better illustrates aspects of the dome, the irradiation chamber side walls 10, the LEDs 9 and the shield 6 in its open position.
(14) FIG. 4 is a side view taken from the left of the exemplary embodiment shown in FIG. 1. FIG. 4 illustrates the position and curvature of the shield 6 in an open position.
(15) FIG. 5 is a left perspective view of the exemplary embodiment shown in FIG. 1 taken from above the device. FIG. 5 shows the shield 6 in a slidably lowered position, reducing the size of the opening 11 to the irradiation chamber relative to when the shield is in its fully open position.
(16) FIG. 6 is an exploded perspective view of the exemplary embodiment shown in FIG. 1 turned upside down to allow viewing of the dome. FIG. 6 depicts a detached tray 2 with air openings 12 corresponding to the openings 13 in the device base 14, exposing the irradiation chamber 8 to visual inspection, including a view of the positions of 15 of the 18 2 W LEDs 9 employed for nail gel curing. An optional motion detector (exemplified by a two-part transmitter-receiver type) that is capable of activating the LEDs may be added with proper alignment, for example, to opposing facie of the dome.
(17) As seen in the embodiment shown in FIG. 6, the base 14 generally conforms to a horseshoe-like shape within a plane, with its outer edges 15 attached to the outer housing 16. The shape of the base's outer edge substantially corresponds to the shape of the bottom edge of the outer housing. The base has a number of perforations 13 or openings to assist in the circulation of air through the device. The base also has a plurality of protuberances 17 on its lower face that may act as feet in situations where the tray has been removed (such as for irradiation of toenails), as well as to provide spacing between the device and any surface upon which it rests, allowing for air to enter or exit the device for cooling purposes.
(18) The base and the dome may be prepared from a wide range of construction materials or combinations of construction materials. Suitable construction materials include those that are reflective of or do not otherwise transmit appreciable UV-VIS light, are durable, lightweight (for portability purposes), or are easily machined or molded into a desired shape. Such materials would be readily apparent to one of ordinary skill in the art, once armed with the present disclosure. It is convenient to prepare these from a metal, such as stainless steel, to take advantage of the durability of the metal, its magnetic properties and the light reflectiveness of its surface. The base and dome may be of a continuous material or prepared separately and subsequently joined together. The shape of the base's inner edge 18 substantially corresponds to the lower edges of the dome such that the dome edges can be attached to the base's inner edge, for example, by soldering or tack welding. In the embodiment shown in FIG. 6, the dome is formed from a single sheet of metal. The interior shape of the dome may be any shape that provides support for the LEDs and that reflects the UV-VIS rays sufficiently to provide curing to the nail gel. In the illustrative embodiment, the dome's apex 19 adopts the shape of a non-equilateral octagon having a longest side with the plane of the apex being generally parallel to the base of the device. The octagon-shaped apex has a plane of symmetry perpendicular to the plane of the dome's apex, the plane bisecting the longest side and the opposing side of the octagon. Extending from each of the non-longest sides of the octagon is a metal petal, each petal shaped substantially as an isosceles trapezoid with the shorter of its parallel sides adjoining one of the non-longest sides of the dome's apex octagon. The outside edge of each of the trapezoid (longer of its two parallel sides) is attached to the base at the base's inside edge, the attachment defining an acute angle between the plane of the base and each petal, such that the petals, so attached, together form the sidewalls of the irradiation chamber. The longest side of the octagon, having no trapezoid-shaped petal, generally defines the top of the opening for the device irradiation chamber.
(19) The embodiment in FIG. 6 also shows grillwork 20 that allows air warmed by electronics' generated heat to escape the internal space in the device, the grillwork located in the apex of the dome which at least in part defines the irradiation chamber.
(20) With reference now to the drawings, and in particular to FIGS. 7 through 10 thereof, a new fingernail gel curing device embodying the principles and concepts of the present invention and generally designated by the reference numeral 21 will be described. The device 21 comprises an outer housing 22, a base, and a dome 32. The dome is visible in FIG. 10. The outer housing, base and dome are attached to one another and configured such that they define an irradiation chamber within the device and below the apex of the dome. They also define a space between the outer housing and the dome in which the electronics, including the LEDs, timers, and power controls are located. FIG. 7 is a perspective view taken from the front upper right of an exemplary embodiment of an LED-equipped fingernail gel curing device of the present invention having a shield 23 that reduces the level of extraneous secondary UV light exposure to which a user is exposed outside the confines of the fingernail gel curing device. The device has an optional stand 24. FIG. 8 is a perspective view taken from the back lower right of an exemplary embodiment of an LED-equipped fingernail gel curing device of the present invention. The rear of the device' outer housing has a viewing window 25 for the timer and three buttons 26 for preset times of irradiation. The device also has an electrical connection 27 for providing power to the device. In FIG. 8, the base of the device is resting on an optional stand. A detachable tray 30 (see FIG. 9) is magnetically and removably affixed to the base of the device in a substantially horizontal manner in relation to the base. The tray is interposed between the base 34 of the device and the optional stand 24. The tray and the stand have a series of matched openings 28 that align with corresponding openings 28 in the base of the device to allow air to enter or exit the internal space as defined by the outer housing, base and dome through the openings. This air moving through the device enables heat generated by the LEDs or other electronics during operation to be removed from the device.
(21) FIG. 9 is a exploded perspective view taken from the front upper right of the exemplary embodiment shown in FIG. 7. FIG. 9 depicts a slidable shield 23 set in the open position above the opening 29 to the irradiation chamber 32. In FIG. 9, a detachable tray 30, with openings 28 for air circulation assistance, is magnetically affixed at the base of the device in a substantially horizontal manner in relation to the base. The optional stand 24 is also depicted.
(22) FIG. 10 is an exploded perspective view of the exemplary embodiment shown in FIG. 7 taken from below the device. FIG. 10 further depicts a detached tray 30 with air openings 28 corresponding to the openings 33 in the device base, exposing the irradiation chamber 32 to visual inspection, including three LEDs 31 of a plurality of such shown inset into the irradiation chamber's dome 32 comprising the irradiation chamber.
(23) As seen in the embodiment shown in FIG. 10, the base 34 generally conforms to a horseshoe-like shape within a plane, with its outer edges attached to the outer housing 35. The shape of the base's outer edge substantially corresponds to the shape of the bottom edge of the outer housing. The base has a number of perforations 33 or openings to assist in the circulation of air through the device. The base also has a plurality of protuberances 36 formed on or attached to its lower face that may act as feet in situations where the tray has been removed (such as for irradiation of toenails), as well as to provide spacing between the device and any surface upon which it rests, allowing for air to enter or exit the device for cooling purposes, such as may be need for example to moderate heat generation by the enclosed electronics. These protuberances are aligned with similarly sized openings 37 in the tray to assist in the alignment of the base and tray. The tray also has plurality of protuberances 38 formed on or attached to its lower face that may act as feet in situations where the optional stand is not present, as well as to provide spacing between the device and any surface upon which it rests, allowing for air to enter or exit the device for cooling purposes. The protuberances in the base are also aligned with similarly sized insets in the optional stand 24 to assist with the alignment of the base to the stand when the tray is not in use, including the alignment of the ventilation openings of the base and stand.
