Magnetic Patents (Class 30/74)
  • Patent number: 8789282
    Abstract: Shaving systems include a replaceable shaving assembly and a cartridge connecting structure for connecting the shaving assembly to a handle. The cartridge connecting structure has a magnetic portion configured to help draw the cartridge onto the handle and retain the cartridge in place when the razor is not in contact with the skin, and a mechanical engagement that provides the necessary retention forces required to keep the system intact during shaving.

  • Patent number: 8381406
    Abstract: A replacement blade razor including a holder having a head portion, a razor head supported by the head portion of the holder, and a blade member removably mounted in the razor head is provided. The head portion of the holder or the razor head includes a holding mechanism that assists in mounting of the blade member in the razor head by attracting or adhering to the blade member and thus causing the razor head to hold the blade member.

  • Patent number: 7913393
    Abstract: A safety razor blade unit mounted for pivotal movement relative to a razor handle about a pivot axis substantially perpendicular to a blade mounted in the blade unit. The blade unit is biased to a rest position by a magnetic return force generated by a set of magnetic elements. The set of magnetic elements are so disposed that the return force increases as the pivotal displacement of the blade unit from the rest position increases.

  • Patent number: 7698822
    Abstract: A personal care apparatus having a hair trimmer, a main part and a head part. The head part being connected to the main part in a region of the main part that is adjacent to the head part and is pivotable relative to the main part. A personal care tool is provided on the head part and comprising a toothed cutting mechanism that has at least one drivable toothed blade and a spring of a U-shaped configuration has a cross-member connected to the head part and two sides co-operating with at least one position extension connected to the main part in the region of each of its two sides. The spring acts between the head part and the main part, and the head part is pivotable by the spring in synchronization with varying displacing forces that act on the head part in the course of a personal care process.

  • Patent number: 7422180
    Abstract: The present invention relates to a magnetic knife stand which comprises one or more slits for inserting knives. On the upper inner side of each inserting slit, one or more magnets are disposed. A hole or a hollow is disposed on the upper inner side of each inserting holes, and the magnet is placed inside the hole or hollow on the upper inner side of the inserting slit. During and after the process of inserting the knives into the knife stand, the magnets will keep the cutting edges of the knives away from the bottom inner sides of the inserting slits, thereby effectively preventing the edges from becoming blunt, which is caused by their rubbing against the inserting slits. The frequency of sharpening the blades can be reduced and the lifespan of the knives can be extended. Further, this magnetic knife stand is more effective in protecting the knife stand from being cut or worn out by the knives. This invention enables the knives to be stored securely in the knife stand.

  • Patent number: 7275461
    Abstract: An apparatus and method for sharpening razor blades and the like whereby rectangularly-shaped magnets are placed end-to-end in a rectangular enclosure that snaps on securely over a razor blade during non-use times in such a manner that the magnetic field generated by the magnets acts upon the cutting edge of the blade so as to maintain the sharpness of the cutting edge.

  • Patent number: 6559563
    Abstract: An improved linear oscillating actuator is capable of minimizing the undesired vibrations while moving first and second oscillators in parallel paths. The first and second oscillators carry first and second drive elements respectively for driving connection to individual reciprocating loads. The first and second drive elements project upwardly respectively from the first and second oscillators such that the first drive element is disposed immediately upwardly of the second oscillator and the second drive elements is disposed immediately upwardly of the first oscillator. With this reverse arrangement of the first and second drive elements relative to the first and second oscillators, the individual oscillating systems each including the oscillator, the drive element and the corresponding reciprocating load can have its mass center disposed in close proximity to a mass center of the actuator, thereby enabling to reduce undesired vibrations which would otherwise occur around the mass center of the actuator.

  • Patent number: 6463661
    Abstract: A magnetic shaving system includes a pre-trimming solution containing particles having magnetic properties and a shaving apparatus having a magnet. The shaving apparatus may include only a magnet or may include a magnet in proximity of a typical razor blade. The pre-trimming solution is applied to the desired area and the magnetic shaving apparatus is applied over the solution. The magnetic solution surround the hairs and causes the hairs to be drawn toward the magnetic shaving apparatus and away from the skin, yielding a more comfortable and effective shave.
