Abstract
Description
- The current application claims a priority to the U.S. Provisional Patent application Ser. No. 61/818,938 filed on May 3, 2013.
- The present invention relates generally to a shearing apparatus. More specifically, the present invention is a baby safe trimming tool that is designed to allow a user to safely trim the fingernails and toenails of a baby with minimal risk of the user inflicting injury on the baby.
- Personal hygiene is a very important part of modern society. There are many components that combine to make up the general term of personal hygiene. Some examples of actions which fall within the realm of personal hygiene include, but are not limited to, brushing teeth, flossing, showering, washing hands, and trimming nails. The trimming of nails may not seem to be linked to personal hygiene, but it is indeed very important to personal hygiene for at least one reason. Longer nails can promote the collection of dirt and grime underneath the nail, and such dirt and grime can be difficult to remove from under the nail. Additionally, long nails can cause some problems. For example, long fingernails can easily scratch other people. Combine this with the aforementioned accumulation of dirt and grime under the nail, and it is not impossible for a person to sustain a scratch wound which can become infected. Long toenails can be an issue as they may become caught on the interior of socks. The toenail can potentially damage the sock or break off and cause a painful hangnail. Therefore, it is important to maintain shorter fingernails and toenails to ensure that none of the issues described above are experienced.
- There are many ways by which a person can trim their nails. The most common method is through the use of a specially designed nail clipper. It is important to use a nail clipper as opposed to simply using a standard pair of scissors. Although it is possible to trim nails using a standard pair of scissors, however this method is highly risky because of the composition of human nails and their proximity to soft flesh. Human nails are comprised of a hard protein substance known as keratin, which can easily cause a standard pair of scissors to slip during cutting, thereby potentially injuring the owner of the nails. It is also possible for a person to trim their nails by using their teeth, however this method is widely considered to be uncivilized and is indeed not very hygienic as the human mouth harbors a wealth of infectious bacteria.
- There are many different types of nail clippers available on the market, however they are all designed for the same task, to trim the nail efficiently and with minimal risk of injuring the user. All currently available nail clippers are efficient at trimming nails, and are indeed quite safe when a user trims their own nails using them. However, it is very easy for the user to injure another person whose nails they are trimming. This is of particular importance for children and babies who are incapable of trimming their own nails and require a parent to perform this task for them. It can be very easy for the parent to accidentally injure their child when using one of the currently available designs of nail clippers; this is very stressful for all parties involved as the parent is upset over causing their child pain, and the child is upset over being in pain. It is clear that there is significant room for improvement in the field of nail trimming apparatuses.
- Therefore, it is an object of the present invention to introduce a baby safe trimming tool that allows a user to trim the nails of another person with reduced risk of injuring the person whose nails are being trimmed. The present invention accomplishes this through a the unique design of the blades and handle. It is a further object of the present invention to be small and nimble enough such that it can be easily used to trim the smaller nails of a human child.

The firstcutting edge 101 is positioned along thefirst blade 10 and is a sharpened edge that allows thefirst blade 10 to slice through the tough keratin of human nails. The slight curve is present because most human nails have a natural curve at the terminating end of each of the nails. By matching the curve of thefirst blade 10 to the curve at the terminating end of the nails as closely as possible, the cutting efficiency of the present invention is maximized. - In reference to
FIG. 2-3 , the firstblunt end 102 is positioned on thefirst blade 10 opposite thefirst handle 11 and prevents thefirst blade 10 from being used in a stabbing manner. The firstblunt end 102 of thefirst blade 10 is rounded such that there is no sharp point that is capable of piercing human flesh. As babies move around quite often, there is the opportunity for the user to miscalculate maneuvering the present invention. In such an instance, the firstblunt end 102 would prevent the baby from being stabbed by the present invention. - In reference to
FIG. 1-2 , thehinge 13 provides a point of connection between thefirst arm 1 and thesecond arm 2. Furthermore, thehinge 13 connects thefirst arm 1 and thesecond arm 2 in a way such that thefirst arm 1 and thesecond arm 2 are allowed to rotate relative to one another, as depicted inFIG. 7-8 . Thehinge 13 may be formed by a small pin, rod, rivet, fastener, etc. Thehinge 13 is perpendicularly connected to thefirst blade 10, wherein ahinge axis 3 traverses along thehinge 13, and thehinge 13 is positioned adjacent to thefirst handle 11. The end of thefirst blade 10 opposite thefirst handle 11 is curved towards thehinge axis 3, such that a mid-curve103 of thefirst blade 10 is coplanar with thehinge axis 3, wherein the mid-curve103 is coplanar with a mid-plane104 of thefirst blade 10, as depicted inFIG. 5 . In the preferred embodiment of the present invention, ahinge 13 cavity is positioned into thefirst blade 10 section, adjacent to thefirst handle 11. Thehinge 13 cavity is a circular hole which is drilled into the material of thefirst arm 1. Thehinge 13 is positioned into and connected to thefirst blade 10 via thehinge 13 cavity. - In reference to
FIG. 2 , thefirst handle 11 section is adjacently connected to thefirst blade 10 just after thehinge 13. Thefirst handle 11 is tapered towards thefirst blade 10, such that the end of thefirst handle 11 opposite thefirst blade 10 is substantially wider than the end of thefirst handle 11 adjacent to thefirst blade 10, as to provide sufficient surface area for gripping and squeezing thefirst handle 11. The width of thefirst handle 11 is large enough such that the user can comfortably apply force to thefirst handle 11, and such that the present invention is sufficiently stable while being operated by the user. In reference toFIG. 2-3 , thefirst spring 12 is adjacently connected to thefirst handle 11 opposite thefirst blade 10. Thefirst spring 12 is constructed from a much thinner piece of material relative to thefirst handle 11 section. Additionally, thefirst spring 12 is thin enough such that thefirst spring 12 is able to elastically deform from the application of small amounts of force. When a force is applied to thefirst arm 1 through thefirst handle 11, the force acts to deform thefirst spring 12. As thefirst spring 12 is deformed, energy is stored within thefirst spring 12, and when the force is removed from thefirst arm 1, the energy is released, thus returning thefirst spring 12 to the original shape of thefirst spring 12. - In reference to
FIG. 1 , thesecond arm 2 comprises asecond blade 20, ahinge hole 23, asecond handle 21, and asecond spring 22. Thesecond arm 2 may be constructed from any number of different materials, however, metal is the most appropriate choice and is the material used in the preferred embodiment of the present invention. Thesecond blade 20 is thin and has a slight curve as can be seen inFIG. 1 , and is adjacently connected to thesecond handle 21. Furthermore, thesecond blade 20 comprises a secondblunt end 202 and asecond cutting edge 201. Thesecond cutting edge 201 is positioned along thesecond blade 20 and is a sharpened edge that allows thesecond blade 20 to slice through the tough keratin of human nails. The slight curve is present because most human nails have a natural curve at the terminating end of each of the nails. By matching the curve of thesecond blade 20 to the curve at the terminating end of the nails as closely as possible, the cutting efficiency of the present invention is maximized. - In reference to
FIG. 2 andFIG. 4 , the secondblunt end 202 is positioned on thesecond blade 20 opposite thesecond handle 21 and prevents thesecond blade 20 from being used in a stabbing manner. The secondblunt end 202 of thesecond blade 20 is rounded such that there is no sharp point that is capable of piercing human flesh. As babies move around quite often, there is the opportunity for the user to miscalculate maneuvering the present invention. In such an instance, the secondblunt end 202 would prevent the baby from being stabbed by the present invention. - In reference to
FIG. 1-2 , thehinge hole 23 provides a point of connection between thefirst arm 1 and thesecond arm 2. Furthermore, thehinge 13 connects thefirst arm 1 and thesecond arm 2 in a way such that thefirst arm 1 and thesecond arm 2 are allowed to rotate relative to one another, as depicted inFIG. 7-8 . Thehinge hole 23 traverses through thesecond blade 20 and is positioned adjacent to thesecond handle 21. The end of thesecond blade 20 opposite thesecond handle 21 is curved towards thehinge axis 3 running through thehinge 13, such that a mid-curve203 of thesecond blade 20 is coplanar with thehinge axis 3, wherein the mid-curve203 of thesecond blade 20 is coplanar with a mid-plane204 of thesecond blade 20. Thehinge 13 is positioned through thehinge hole 23, wherein thesecond arm 2 is pivotally connected to thehinge 13 and the first curved blade and the second curved blade are scissionably aligned. More specifically, thefirst cutting edge 101 and thesecond cutting edge 201 are scissionably aligned. - In reference to
FIG. 2 , thesecond handle 21 section is adjacently connected to thesecond blade 20 just after thehinge hole 23. Thesecond handle 21 is tapered towards thesecond blade 20, such that the end of thesecond handle 21 opposite thesecond blade 20 is substantially wider than the end of thesecond handle 21 adjacent to thesecond blade 20, as to provide sufficient surface area for gripping and squeezing thesecond handle 21. The width of thesecond handle 21 is large enough such that the user can comfortably apply force to thesecond handle 21, and such that the present invention is sufficiently stable while being operated by the user. - In reference to
FIG. 2 andFIG. 4 , thesecond spring 22 is adjacently connected to thesecond handle 21 opposite thesecond blade 20. Thesecond spring 22 is constructed from a much thinner piece of material relative to thesecond handle 21 section. - Additionally, the
second spring 22 is thin enough such that thesecond spring 22 is able to elastically deform from the application of small amounts of force. When a force is applied to thesecond arm 2 through thesecond handle 21, the force acts to deform thesecond spring 22. As thesecond spring 22 is deformed, energy is stored within thesecond spring 22, and when the force is removed from thesecond arm 2, the energy is released, thus returning thesecond spring 22 to the original shape of thesecond spring 22. - The
first spring 12 engages thesecond spring 22 opposite thefirst handle 11 and thesecond handle 21, such that when a force is applied to either thefirst arm 1 or thesecond arm 2, both thefirst spring 12 and thesecond spring 22 deform. In reference to FIG. 3 , thefirst spring 12 comprises aspring notch 121, while thesecond spring 22 comprises aspring tab 221. Thespring tab 221 is positioned on thesecond spring 22 opposite thesecond handle 21, wherein thespring tab 221 has a smaller width than the remainder of thesecond spring 22. Thespring notch 121 is positioned through thefirst spring 12 opposite thefirst handle 11, and provides an opening with a width slightly larger than the width of thespring tab 221. Thespring tab 221 engages thespring notch 121, wherein thespring tab 221 traverses through thespring notch 121, thus securely engaging thefirst spring 12 to thesecond spring 22.- The present invention is operable between an open configuration, as shown in
FIG. 1 , and a closed configuration, as shown inFIG. 7 , wherein the open configuration is achieved by applying zero force to either thefirst handle 11 or thesecond handle 21. In the open configuration, thefirst blade 10 and thesecond blade 20 are positioned adjacent to each other, such that there is a gap between thefirst cutting edge 101 and thesecond cutting edge 201 for positioning the material to be cut. Both thefirst spring 12 and thesecond spring 22 are in the original, non-deformed shape, and engage each other such that thefirst arm 1 and thesecond arm 2 cannot freely pivot about thehinge axis 3. - The closed configuration is achieved by applying a force to the
first handle 11 orsecond handle 21 in order to overcome the spring force of thefirst spring 12 and thesecond spring 22. As the force is applied by the user, thefirst spring 12 and thesecond spring 22 collapse, allowing thefirst arm 1 and thesecond arm 2 to pivot about thehinge axis 3. As thefirst arm 1 andsecond arm 2 pivot, thefirst cutting edge 101 and thesecond cutting edge 201 progressively engage each other, producing a shear force to cut material positioned in the gap between thefirst blade 10 and thesecond blade 20. The closed configuration is reached when thefirst blade 10 and thesecond blade 20 completely overlap each other, wherein thefirst blade 10 and thesecond blade 20 are flush with one another. At this point, the material positioned in the gap between thefirst blade 10 and thesecond blade 20 will be fully cut along the length of thefirst cutting edge 101 and thesecond cutting edge 201. - In reference to
FIG. 2 , thesecond handle 21 comprises astop 213. Thestop 213 is positioned in between thefirst handle 11 and thesecond handle 21, and is positioned adjacent to thesecond spring 22. Thestop 213 is a protrusion that extends out from thesecond handle 21 towards thefirst handle 11. When in the closed configuration, the end of thestop 213 opposite thesecond handle 21 engages thefirst handle 11, as shown inFIG. 8 , thus preventing thefirst arm 1 and thesecond arm 2 from pivoting any further. - The present invention can be constructed with a number of grip configurations. In reference to
FIG. 1-4 , in a first grip configuration, thefirst handle 11 comprises afirst grip area 111 and a first plurality ofgripping grooves 112, while thesecond handle 21 comprises asecond grip area 211 and a second plurality ofgripping grooves 212. Thefirst grip area 111 is positioned on thefirst handle 11 opposite thesecond handle 21 and provides a surface of thefirst handle 11 for the user to grip thefirst arm 1. Similarly, thesecond grip area 211 is positioned on thesecond handle 21 opposite thefirst handle 11 and provides a surface of thesecond handle 21 for the user to grip thesecond arm 2. The first plurality ofgripping grooves 112 is positioned across thefirst handle 11 about thefirst grip area 111, while the second plurality ofgripping grooves 212 is positioned across thesecond handle 21 about thesecond grip area 211. The first plurality ofgripping grooves 112 and the second plurality ofgripping grooves 212 provide thefirst grip area 111 and thesecond grip area 211, respectively, with an irregular surface. The irregular surface of thefirst handle 11 and thesecond handle 21 enhances the user's grip as compared to a smooth surface, thus reducing or eliminating the possibility of the present invention slipping from the user's hand while being used. - In reference to
FIG. 9-12 , in a second grip configuration, thefirst arm 1 further comprises afirst loop 14, while thesecond arm 2 further comprises asecond loop 24. Thefirst loop 14 is adjacently connected to thefirst handle 11 opposite thesecond handle 21, such that the user may insert a thumb or finger(s) through thefirst loop 14 when gripping thefirst handle 11; wherein the opening through thefirst loop 14 is directed across thefirst handle 11. Similarly, thesecond loop 24 is adjacently connected to thesecond handle 21 opposite thefirst handle 11, such that the user may insert a thumb or finger(s) through thesecond loop 24 when gripping thesecond handle 21; wherein the opening through thesecond loop 24 is directed across thesecond handle 21. Thefirst loop 14 is positioned on thefirst handle 11 adjacent to thefirst spring 12, while thesecond loop 24 is positioned on thesecond handle 21 adjacent to thesecond spring 22. In this way, less force can be exerted by the user in order to operate the present invention. - In the second grip configuration, the
