Description
BACKGROUND
This invention relates to fingernail and toenail clippers, specifically to nail clipping retaining devices that mount to nail clippers to prevent the annoying and unsanitary scattering of nail clippings during the manicuring procedure.
DESCRIPTION OF PRIOR ART
A typical nail clipper of the class which includes U.S. Pat. No. 3,013,334, issued Aug. 29, 1960 to Henry W. Bassett, consist of a pair of oppositely bowed spring members, an upper movable member and a lower stationary member. These spring members are joined together at one end by a weld or rivet, creating a spring mechanism when the opposite end of the spring members are compressed, creating a joined end and a free end. On most nail clippers, at the joined end, a rivet secures a pivoting nail file to the clipper. At the free end of the mechanism, opposing cutting jaws are coupled together by a lever arm pivot pin and a lever arm with a built in fulcrum. The pivot pin passes through both spring members via aligned holes near the cutting jaws at the free end, with the holes being slightly larger than the shaft of the pivot pin and the head of the pivot pin engaging the lower stationary spring member. The fulcrumed lever arm is then connected to the pivot pin above the upper movable member under the spring force of both compressed spring members creating an initially loaded compressive cutting mechanism. The head of the lever arm pivot pin prevents the pin from being pulled through the aligned hole in the lower stationary spring member when the fulcrumed lever arm is depressed.
With the aforementioned nail clipper design, the nail clippings shoot through the openings between the spring members and fly about the room in a random manner.
An exorbitant amount of time, energy and money has been spent trying to solve the annoying and unsanitary problem of nail clipping projectiles flying about the room during the manicuring process. There are more than fifty patents related to nail clipping retaining devices. Each of these devices has certain drawbacks that have inhibited their marketing and manufacturing feasibility.
After an examination of the prior art, five common methods of mounting the retaining devices were found:
1. Small plastic tabs that fasten the retaining device to the lower stationary spring member of the nail clipper.
2. Fasteners such as rivets which connect the retaining device to the nail clipper via holes in the spring members.
3. Rubber pouch retainers that are inserted between both spring members at the cutting end of the nail clipper and circumvent the lever arm pivot pin as a fastening means.
4. Full enclosures, usually manufacture of rubber, which slide over both spring members and elastically fasten to the nail clipper.
5. Fixed retainers which are either part of the lower stationary spring member or have a fastening hole which fits between the head of the lever arm pivot pin and the lower stationary spring member during the initial assembly of the nail clipper.
An examination of the prior art also suggested the following manufacturing and marketing issues:
1. The ability or ease of mounting and dismounting the retaining device for the purpose of emptying accumulated nail clippings, cleaning and sterilization.
2. Costly redesigns of conventional nail clippers with fixed retaining devices and mechanical apparatuses to increase ease of emptying.
3. Retaining devices of plastic that fasten to only one particular nail clipper design, relying on exact dimensions of the nail clipper and utilize a variety of different mounting methods.
Each device described performs the same function, the prevention of nail clippings from being strewn about, but none of the fastening methods discussed allow ease of mounting and dismounting for the purpose of emptying accumulated nail clippings, cleaning and sterilization of the device.
The following patents fall under category 1 previously defined for nail clipping retaining devices that are difficult or impossible to dismount:
U.S. Pat. No. 2,995,820 issued Jun. 23, 1958 and U.S. Pat No. 3,031,754 issued Aug. 15, 1961 to Pocoski, U.S. Pat. No. 3,169,312 issued Mar. 25, 1963 to Charles H. Fink, U.S. Pat. No. 3,188,737 issued Jun. 15, 1965 to P. J. Chase, and U.S. Pat. No. 4,062,109 issued Dec. 13, 1977 to Mana Min.
The following patents fall under category 2 previously defined for costly re designs of the conventional nail clipper with fixed retaining devices and elaborate actuating mechanisms which attempt to increase openings between cutting jaws to allow ease of emptying ac cumulated nail clippings.
U.S. Pat. No. 3,986,257 issued Oct. 19, 1976 to Masao Kiura, U.S. Pat. No. 5,072,511 issued Dec. 17, 1991 to Abraham E. Ro, and U.S. Pat. No. 5,261,160 issued Nov. 16, 1993 to Leonardo F. Campagna.
The following patents fall under category 3 previously defined for retaining devices which rely on small plastic tabs to secure the retaining device to specifically designed nail clippers and can not be interchanged between different manufacturers nail clippers because of dimensional restraints:
U.S. Pat. No. 2,887,773 issued Jun. 6, 1957 to Donald P. Killen, U.S. Pat. No. 2,970,376 issued Mar. 16, 1960 to Chi Sheng Kuo, U.S. Pat. No. 4,380,120 issued Apr. 19, 1983 to William Hannon. U.S. Pat. No. 4,640,011 issued Feb. 3, 1987 to William L. Gamble, U.S. Pat. No. 5,195,544 issued Mar. 23, 1993 to Vince Campagna.
In particular, it should be noted that the Hannon patent teaches a device that is constructed of plastic material. In one embodiment, the Hannon device is held onto the lower arm by means of projections 44a and 46a as shown in FIG. 4. The Hannon patent also teaches an alternate method of securing the nail clipping retaining device by means of applying adhesive strips to keep the clipping retainer affixed to the lower arm of the nail clipper.

BRIEF DESCRIPTION OF THE INVENTION
A unique and novel aspect of this invention is its design and mounting method. The nail clipping retaining device consists of a u-shaped elongated channel with a central bottom section and two vertical side sections engineered to cover side openings of a conventional nail clipper to prevent the annoying and unsanitary scattering of nail clippings during the manicuring process.
The device utilizes as a fastening system, a slotted mounting catch in the central bottom section of the u-shape channel. This slotted mounting catch slides into position between the head of the lever arm pivot pin and the lower stationary spring member of a typical nail clipper. The force between the head of the lever arm pivot pin and lower stationary spring member of the initially loaded compressive cutting mechanism of a typical nail clipper secures the retaining device tightly to the lower spring member. The device can be easily and effortlessly mounted and dismounted for the purpose of evacuating accumulated nail clippings, cleaning and sterilization.
To mount the retaining device to a nail clipper, one positions the retaining device on the lower stationary member of the nail clipper behind the lever arm pivot pin and slides the retaining device under the head of the lever arm pivot pin. The device slides into position with a snap and once coupled to the nail clipper, the retaining device is secured in check by the nail file mounting rivet which passes through the spring members at the opposite end.
To dismount the retaining device from a nail clipper, one raises the rear of the device slightly to clear the protruding rivet on the nail clipper and slides the device from under the head of the lever arm pivot pin. The nail clippings accumulate within the nail clipper and are dumped out via the opening between the jaws.
After the manicure is completed, the retaining device is removed and all remaining nail clippings are cleared from between the spring members. At this point, the nail clipper and retaining device can be sterilized to prevent infection. The retaining device may then be remounted to the nail clipper for future use.
