  • Patent number: 4993154
    Abstract: A shaving apparatus is described that has a handle, a bifurcated expansion means with one end connected to the handle and with another end attached to a razor head containing at least one blade and at least one spacer that are retained in a base in such a manner so as to allow the blades and spacers to move longitudinally as the base, blades and spacers are moved from a convex curve through a straight configuration to a concave curve to accommodate the various surfaces requiring shaving on the body. There is an adjustment means on the apparatus that allows the user to select the curvature of the blade desired without visually referencing the apparatus. There is a contraction means to enhance the movement of the blades from the expanded position of the concave configuration to the retracted position of the convex configuration.

  • Patent number: 4961262
    Abstract: An eyebrow shaving apparatus comprised of an elongate handle having at least one blade and preferably a pair of blades mounted on a flat portion of the handle. The blades are preferably arcuate in shape so as to enable an easy trimming or shaving of a user's eyebrows. The blades have sharp edges facing away from the flat surface of the handle and are arranged so that the entire shaving apparatus can easily be manipulated by the user. Furthermore, the handle is provided with an angularly bent portion so as to enable the user to grasp the handle and easily trim the eybrows while also displacing the user's hands from a line of sight. In this way, a user can carefully and easily munipulate the apparatus while viewing in a mirror. The apparatus is also highly effective and relatively safe in use.

  • Patent number: 4955136
    Abstract: A shaving apparatus including a handle with a rigid portion for gripping, and a bendable, non-resilient portion which receives a disposable, detachable blade unit. The bendable, non-resilient portion can be bent to a fixed angle to provide a large number of possible handle angles for shaving. Alternatively, a shaving apparatus is provided which forms a twin-edged razor blade assembly from two single- or double-edged blades. The device includes a blade assembly comprising two blades mounted on a step-shaped insert in an offset relationship with a spacer between the blades. The blade assembly is locked in the shaving apparatus between a rotating plate and a shank by either a left or right half cover during use. When not in use, both half covers cover the exposed blades. Either half cover forms a handle with a handle extension slidably received in either half cover in a longitudinal arrangement.

  • Patent number: 4845848
    Abstract: This invention is concerned with the mounting of a flexible razor blade on a flexible holder such that the blade may be flexed about an arc having a radius as small as 1/8" or smaller to permit the blade to flow over protrusions or be flexed to shave through dimpled areas of the skin being shaved. The razor is useful for shaving over the jaw bone or shin bone areas for example without cutting the skin and may be pressed by the fingers of the user to delicately shave most any contoured area found on the normal skin of a human being.

  • Patent number: 4587730
    Abstract: A sleeve for a safety razor having a handle with a blade-carrying head pivotably attached thereto includes a body portion generally elliptical in cross-section formed by two inwardly-curved opposing side walls joined along one pair of opposing edges by a flat top wall with an aperture between the other pair of opposing edges, further including flanges connected to the edges of the side walls adjacent the aperture and a set of tabs extending laterally from the outer surface of one of the curved side walls. In use, the sleeve is slid over the razor head and held in place by engagement of the flanges with the portion of the handle extending through the aperture. When a plurality of sleeve-bearing razors are stacked vertically atop one another such as during shipping, storage or sale, the tabs interlockingly engage the handle portion of the adjacent razor and thereby prevent premature removal of the sleeves from the razors.
