The present invention relates generally to the field of clippers and more particularly to an adjustable double nail clipper.
Nail clippers are known in the art. Nail clippers can be found in the selves of the local convenience store. Most clippers are aimed at cutting fingernails. Toenails, on the other hand, are of a different character than fingernails. First, toenails are usually thicker and tougher than fingernails. Second, in many persons, toenails include extra material between the toe and the nail or are ingrown, especially in older people. Third, a significant percentage of the population has a nail fungus or other manifestation that makes toenails particularly hard to cut with prior art clippers or scissors. In addition, almost all prior art clippers are fixed in terms of the cutting channel size. It would be desirable to have an adjustable clipper to move between fingernails and toenails. It would also be advantageous to have a clipper that had a strong enough grip to cut really tough toenails with the problems listed above.
Jurena in U.S. Pat. No. 3,555,675 shows an adjustable nail clipper. It only has a single lever. Jung in U.S. Pat. No. 4,903,514 teaches a nail clipper that can also hold keys. None of these prior art clippers solves the problem of cutting touch, possibly ingrown or otherwise difficult toenails that require extra force, while still being able to adjust to fingernails.
The present invention relates to a double levered, adjustable nail clipper that is particularly adapted to overcome the difficulties in cutting toenails. A typical embodiment has two action levers in opposed positions that permit applying twice the force of a single lever clipper. In addition, at least one of the action levers is rotatable, turning a threaded penetrating pin that adjusts the width of the cutting channel. This allows a simple conversion in the gap width of the cutting channel between the jaws to a close configuration for fingernails and a wide configuration for toenails. A particular embodiment optionally allows the attachment and carrying of keys, such as house keys and the like, at the base of the unit. Finally, a particular embodiment has only a single lever and can also optionally carry keys.
Attention is now directed at several figures that illustrate features of the present invention.
Several drawings and illustrations have been presented to aid in understanding the present invention. The scope of the present invention is not limited to what is shown in the figures.
The present invention relates to a robust toenail/fingernail clipper that in particular embodiments is equipped with two opposing action levers permitting twice the pinching force to be applied to the jaws to cut tough toenails. In addition, at least one of these action levers rotates to adjust the width of the cutting gap by turning a threaded through-pin. This allows selection of a small gap for fingernails and a large gap for toenails, with several steps in between these two settings.
