OF THE INVENTION
1. Field of the Invention
The present invention relates to fingernail clippers, and more specifically to a new and improved self-operating, hands-free fingernail clipper especially adapted for individuals who, through lack of strength in one or both hands or because of any deformity, find using conventional clippers too difficult or impossible.
2. Description of the Prior Art
Various types of nail clippers are known in the prior art. A typical example of such an item is found in:
U.S. Pat. No. 7,222,427 to Kaidi et al. This patent teaches a conventional leaf-spring type clipper having a sleeve attached to catch clippings.
U.S. Pat. No. 7,194,807 issuing to Weiss is a variation of the former with a different apparatus to catch the clippings.
U.S. Pat. No. 7,159,318 to Farag discloses a clipper unit having a shield with various configurations of shapes cut into it for the purpose of sticking the user's nail through to be sheared off.
U.S. Pat. No. 6,865,812 issuing to Martin Jr. primarily teaches a toenail clipper due to the presence of an extended handle.
U.S. Pat. No. 6,438,845 to Jung teaches a scissor-type nail clipper.
U.S. Pat. No. 4,819,673 to McMullen teaches a clipper somewhat similar in concept to a conventional leaf-spring type clipper wherein the cutters are positioned on the side rather than on the leading edge. Lastly,
U.S. Pat. No. 3,986,257 to Kiura discloses another nail clipper similar to a conventional leaf-spring type clipper but having a chamber to collect the clippings.
While all the above-mentioned devices may be suitable for their intended usage, none is specifically designed for persons who have some degree of difficulty in squeezing the clipper\'s levers due to inherent deformity or strength problems, nor are these devices particularly adapted for persons who suffer from certain bone and/or joint diseases whose strength and/or flexibility negates the use of conventional means to cut their nails.

OF THE INVENTION
The present invention addresses the deficiencies of prior art nail clippers as relate specifically to usage by persons having digital strength problems or joint/bone disease that result in lack of strength and/or deformity. The present invention is a new and greatly improved hands-free nail clipper which can be used by the group of individuals described above as well as by persons who have no problem using the currently available, conventional-type nail clippers. The nail-clipper of this invention makes use of an electric motor-driven, Tri-lobed cam to power a conventional leaf-spring type clipper. When the unit of this invention is placed on a surface and turned on, the user can easily place his/her nail in the clipper and allow the motorized cam to depress the clipper handle to operate the clipper; or, in the case of individuals with some degree of deformity, such as caused by arthritis or other bone diseases, such individuals will be able to guide each fingernail into the clipper with the other functional hand. Because this motor runs continuously once the activation switch is activated, the user needs only to sit in front of the unit and guide his/her nails into the cutting edges.
Therefore it is an object of the present invention to provide a new and improved self-operating, hands-free fingernail clipper for use by persons who may be unable to squeeze a conventional nail clipper or who may be unable to physically align their fingernails with a conventional clipper while simultaneously try to manage a conventional clipper with the other hand.
It is another object of the present invention to provide a new and improved self-operating, hands-free fingernail clipper.
It is a further object of the present invention to introduce a self-operating fingernail clipper which is of durable and reliable construction.
It is a still further object of the present invention to provide self-operating clipper which is of simple construction, providing low cost of manufacture and assembly, and which can be easily and efficiently manufactured and marketed.
For a better understanding of the present invention, reference should be made to the accompanying drawings and description of the Preferred Embodiment.
