the present invention provides a device 10 to shape a nail 100 and a method of using the device 10 to achieve a uniform manicure in less time than prior manicuring methods . in one embodiment , the device 10 includes a pair of blades 20 a and 20 b , a first lever 30 and a base 40 which are separated by a biasing element 50 biasing a first end 32 of the first lever 30 and a first end 42 of the base 40 apart . the biasing element 50 may comprise a metal or plastic spring or springs , a tab or strut - like element made of resilient and compressible material , a resilient biasing member . one of ordinary skill in the art would understand there are many ways to provide resilient bias between two elements which are associated at one end in a spaced apart manner . the blades 20 a and 20 b each comprise a cutting end , 34 and 44 . the cutting ends further comprise a shape 25 . the device 10 may comprise integration of a second end 36 of the first lever 30 which may be associated with the blade 20 a near its cutting end 34 for example , at 70 . the second end 46 of the base 40 may be associated with the lower blade 20 b near its cutting end 44 . in another embodiment , the lower blade 20 b may be an integrally formed part of the base 40 or the lower blade 20 b may be formed to also serve as the base 40 . one embodiment of the device 10 comprises engagement 60 of a non - cutting end 20 c and 20 d of each of the blades 20 a and 20 b to each other , with the biasing element 50 positioned oppositely near the cutting ends 34 and 44 . the first lever 30 is associated with blade 20 a near the cutting end 34 ; the base 40 is associated with blade 20 b near its cutting end 44 . alternatively , the device 10 may comprise means to detachably associate 80 the cutting ends 34 and 44 and the blades 20 a and 20 b . this detachable association 80 may comprise a snap - lock , biasing device , pin , friction fit , or the like . this embodiment would allow the device to employ interchangeable cutting end pairs , having different shapes for cutting the nails . in one embodiment the first lever 30 comprises a depression or stand - off 90 which extends toward the blade 20 a ; when pressure is applied to the first lever 30 the stand - off leverages that pressure to the blade 20 a to close its cutting end 34 against cutting end 44 . in some embodiments the base 40 may include a similar stand - off 90 on the base 40 for better positioning of the blade 20 b and cutting end 44 relative to blade 20 a . the embodiments comprising blade 20 b integrated with base 40 or serving as base 40 may provide means for operation that does not require the user to squeeze the first lever 30 and the base 40 together while holding the device but , instead , allows for operation by placing the base 40 on a surface and pressuring the first lever 30 toward the base to cut the nail 100 . in some embodiments the base 40 may be formed substantially the same as the first lever 30 and may or may not include a stand off . this embodiment would be more amenable to the user holding the assembly 10 in one hand between fingers and thumb and squeezing the lever 30 and the base 40 together to cut the nail 100 . however , an appropriately shaped base 40 could allow operation either by squeezing lever 30 and base 40 together , or by pressuring the lever 30 while base 40 rests against a work surface 110 . the method of using the device requires selecting a pair of generally identically shaped cutting ends 34 , 44 of the appropriate and desired shape 25 and attaching them to blades 20 a and 20 b ; alternatively , one may select a device 10 that includes cutting ends 34 , 44 permanently affixed to blades 20 a and 20 b . the upper cutting end 34 associated with lever 30 is then positioned above the first finger &# 39 ; s nail &# 39 ; s distal edge 102 , the lower cutting end 44 below , with the center of the blades &# 39 ; shape generally over the center of the nail &# 39 ; s distal edge ; the base 40 and the lower cutting end 44 may be generally horizontally aligned although such alignment is not required . in one embodiment , a horizontally parallel alignment is achieved by using a base 40 shaped to provide a spaced apart relationship between the lower cutting end 44 and a work surface 110 on which the base 40 rests , thereby allowing the finger to rest on the work plane 110 and the nail &# 39 ; s distal edge 102 to easily slide between the cutting ends 34 and 44 . other arrangements may be employed to allow the finger to rest appropriately below the lower cutting end , including providing a finger rest associated with the device , or a slightly raised platform 40 a upon which the cutting ends and blades are mounted . once positioned , the base 40 of the device 10 rests on work surface 110 . the first lever 30 is depressed and the cutting ends 34 and 44 cut the nail in the shape 25 of the cutting ends 34 and 44 . the shape 25 may be oval , square , round , oblong , etc . each cut is substantially identical in shape and clean . minimal smoothing of the cut edge is all that is required . each nail can , in its turn , be inserted between the cutting ends and using the free hand or other means of applying pressure , the first lever 30 is easily pressed downward ( more particularly minimized in embodiments comprising the stand - off ) toward the work surface 110 and the base 40 to simply effect the nail &# 39 ; s cut without two - handed operation , and with minimal pressure . one advantage of the present invention is to facilitate minimal cut strokes to assist those with arthritis or other painful maladies of the joints or wrist that may be bothered by squeezing . a second advantage of the present invention is to provide a simpler method to achieve a good manicure without the assistance of another person . a third advantage is to avoid multiple cuts and to minimize or eliminate the time consuming task of adjusting the shape of each of the nails relative to the others to achieve uniformity in shape and length . the present invention has been described with particularity , however , it should be understood that the shape of the blade pair may take on any of many . further , while it is important that one blade be associated with the lever , and another blade be associated with the base ( or another element highly similar to the lever ) in order to provide the simplest use , the exact means and arrangement of that association is not particularly important so long as it addresses the need to provide means to cut a fingernail that requires less hand strength or coordination . one embodiment describes one or two stand - offs or depressions positioned against either or both blades in a manner to create means for closing the cutting blades using less movement of the lever , and / or less pressure to do so . the simplicity of cutting a nail by simply pressing on the lever while the base is supported by a table or counter - top is inventive . further , providing pre - shaped blade reduces the efforts required to obtain a uniform nail set . detachable / replaceable blades further extend the usefulness of the assembly by allowing its use to attain different nail shapes as desired . other relationships that allow for such ease of use are also contemplated by the invention .
a nail clipping device is disclosed which is designed to increase ease of use for users with diminished capacity , improve uniformity , and increase efficiency of a manicure . the device includes a lever and base each associated with a blade ; the blades are biased apart and the device includes at least one stand - off to magnify pressure applied to the lever . the base may be designed to rest on a work surface eliminating the need for a user to squeeze the blades together . a cutting end of each blade comprises a shape ; in one embodiment the cutting ends are detachable allowing interchangeability for different shapes .
