Reusable Modular False Nail Assembly with Concealed Prong-and-Socket Engagement

Abstract

A reusable false fingernail device includes a false nail and a nail plate configured to be secured to a natural nail. The false nail and nail plate engage through concealed mechanical coupling without adhesive. In one form, a convex mound on the nail plate contains a female socket that receives a male prong on the false nail to form a dovetail-type joint. In another form, the false nail includes an attachment tab slidingly received in a grooved channel having one or more retention notches for adjustable locking. In yet another form, a grooved channel within the false nail engages one or more projecting male tabs on the nail plate. Each configuration permits repeated attachment and removal while maintaining natural appearance, comfort, and structural integrity. The device limits excessive repeated use of adhesives, improves hygiene, accommodates nail growth, and provides durable, customizable artificial nails.

         4 . The device of  claim 1 , wherein said convex protruding mound has a dome-shaped exterior configured to mate with a complementary concavity in said false nail. 
     
     
         5 . The device of  claim 1 , wherein said convex protruding mound has a downward sloped exterior to reduce bulk and conceal said false nail plate. 
     
     
         6 . The device of  claim 1 , wherein said false nail comprises a plurality of male prongs and said false nail plate comprises a corresponding plurality of female sockets arranged to engage said plurality of male prongs. 
     
     
         7 . The device of  claim 6 , wherein said recessed female socket is located between adjacent male prongs of said plurality of male prongs on said false nail, and said male prong is located between adjacent female sockets of said corresponding plurality of female sockets on said false nail plate. 
     
     
         8 . The device of  claim 6 , wherein said plurality of male prongs and said corresponding plurality of female sockets are symmetrically arranged relative to a longitudinal axis of said false nail. 
     
     
         9 . The device of  claim 6 , wherein said plurality of male prongs and sockets are asymmetrically arranged to distribute stress and resist lateral rocking. 
     
     
         10 . The device of  claim 1 , wherein said convex protruding mound is positioned selectively at a center, a cuticle end, or a tip end of said false nail plate. 
     
     
         11 . The device of  claim 1 , wherein said convex protruding mound may be dome-shaped or sloped to provide concealment and comfort flexibility. 
     
     
         12 . The device of  claim 1 , wherein said false nail plate remains secured to said natural fingernail while said false nail is repeatedly attached and detached without deformation. 
     
     
         13 . The device of  claim 1 , wherein said reusable false fingernail device is configured as a false toenail sized and shaped for toenail anatomy. 
     
     
         14 . A reusable false fingernail device comprising:
 a false nail having an attachment tab projecting from an underside;   a nail plate configured to be secured to a natural fingernail, said nail plate including a convex protruding mound, said convex protruding mound having a longitudinal grooved channel dimensioned to slidingly receive said attachment tab;   wherein said longitudinal grooved channel includes at least one retention notch configured to engage said attachment tab to lock said false nail in place;   wherein said longitudinal grooved channel lacks a stopper wall at a cuticle end and said convex protruding mound on said nail plate is shortened in length, thereby permitting said false nail to slide into said longitudinal grooved channel from a tip end for engagement; and   wherein said attachment tab and said longitudinal grooved channel remain concealed beneath said false nail when engaged, and said false nail is removably secured without adhesive.   
     
     
         15 . The device of  claim 14 , wherein said longitudinal grooved channel includes a plurality of retention notches spaced along a length of said longitudinal grooved channel, each notch defining a distinct locking position to permit repositioning of said false nail to accommodate nail growth. 
     
     
         16 . The device of  claim 14 , wherein said nail plate comprises two parallel grooved channels and said false nail comprises two corresponding attachment tabs, each receivable in a respective channel. 
     
     
         17 . The device of  claim 14 , wherein said attachment tab and said longitudinal grooved channel are formed of polymeric material dimensioned to flex during an engagement and provide an audible click when seated in said retention notch, said engagement exhibiting characteristics of a snap-fit annular joint. 
     
     
         18 . The device of  claim 14 , wherein a shortened mound geometry reduces profile thickness, enhancing concealment beneath said false nail. 
     
     
         19 . The device of  claim 14 , wherein a sliding configuration of said longitudinal grooved channel and said attachment tab permits repeated attachment and removal cycles without structural deformation. 
     
     
         20 . A reusable false fingernail device comprising:
 a false nail having a hollowed underside curved to accommodate a nail plate, said hollowed underside further comprising a hollowed grooved channel embedded within said false nail, said hollowed grooved channel including a plurality of retention notches comprising a first retention notch and a second retention notch;   said nail plate configured to be secured to a natural fingernail, said nail plate including a plurality of projecting male tabs, comprising at least a first projecting male tab, each dimensioned to slidingly engage said hollowed grooved channel of said false nail;   wherein said hollowed grooved channel includes at least one more retention notch than said plurality of projecting male tabs;   wherein said plurality of projecting male tabs are curved or sloped to facilitate smooth engagement; and   wherein said hollowed grooved channel and said plurality of projecting male tabs remain concealed beneath said false nail when engaged, and said false nail is removably secured without adhesive.   
     
     
         21 . The device of  claim 20 , wherein said male tab of said nail plate is positioned selectively at a center, a cuticle end, or a tip end of said nail plate.
