    Abstract: A razor assembly is provided that includes a razor cartridge with one or more razor blades, a shaving aid body, a handle, and a linkage pivotally connected to the handle. The linkage is connected to the razor cartridge and the shaving aid body in a manner such that the razor cartridge and the shaving aid body are moveable relative to the handle. Movement of one of the razor cartridge or the shaving aid body in a first direction causes the other of the razor cartridge or the shaving aid body to move in a second direction substantially opposite the first direction. As a result, the positions of the shaving aid body and the razor cartridge are continuously adjusted to maintain the contact surface of the shaving aid body approximately co-planar with the cutting edges of the razor blades within the razor cartridge.

    Abstract: A shaving system for use with mechanical hand-held shavers includes a housing in which is disposed a DC motor, an eccentric weight coupled to a shaft of the motor, and a DC power source. The eccentric weight and motor shaft are oriented such that the axis of vibrations produced by the motor are parallel to an axis of the cutting edge of a razor blade attached to a handle in mechanical vibratory communication with the motor. The result is vibratory displacement of the razor blade, typically back-and-forth, over a range approximating the dimension of a human hair. In one embodiment a housing accepts the handle of a generic shaver, and in a second embodiment the housing is bifurcated and the handle of a shaver.

The blades have apertures that allow lubricants removed from a surface of a shaver by the cutting edge of the blade to be transported through the blade and supplied to the cutting edge of the adjacent blade or to a skin engaging surface of the cap member, whichever the case may be. The apertures in the blades define flow paths that allow lubricants to reach successive cutting edges or skin engaging surfaces, thereby reducing irritation to the shaver. The blades are spaced apart by spacers that are constructed with passages that allow the free flow of lubricant through adjacent flow paths. The cap member includes passages that allow the free flow of lubricating agents through the flow paths to the skin engaging surface of the cap member.

    Abstract: In-line razor-blade shaving devices feature two sets of razor blade strips pointing inwardly in opposite directions. The devices are designed for safely and rapidly shaving hair from large body portions such as legs and arms. Each device features an elongated handle arranged in line with an elongated bi-directional razor blade head. Each set of razor blade strips in the head may be provided with one or more straight razor-sharp edges, which point in the same direction, while the blade edges of the two sets point inwardly toward from one another, generally in opposite directions. The edges of blade strips of the two sets may be arranged in one common working plane, or each set may be in its own working plane, with the planes at an angle to one another. The working planes are defined by the elongated front and rear guard surfaces of the blade-edge guarding system on the face of the razor head. These guard surfaces contact a user's skin before and after the razor-sharp edges to help ensure safe shaving.

  • Patent number: 6161288
    Abstract: Single-head bi-directional razor devices having an elongated bi-directional razor head with flexible guards along both outer longitudinal edges are disclosed. The razor head may be constructed as a removable cartridge if desired, and has first and second sets of razor blade strips are positioned within the head in a substantially common working plane, with their sharpened edges pointing outwardly. The working plane is defined in part by the flexible guards, which preferably are formed as elongate pliable fins arranged adjacent the outer edges of the razor head. The first and second sets of razor blade strips may consist of one, two or three razor blade strips, and are each preferably mounted for individual spring-loaded movement.

  • Patent number: 6141875
    Abstract: In-line razor-blade shaving devices feature two sets of razor blade strips pointing outwardly in opposite directions. The devices are designed for safely and rapidly shaving hair from large body portions such as legs and arms. Each device features an elongated handle arranged in line with an elongated bi-directional razor blade head. Each set of razor blade strips in the head may be provided with one or more straight razor-sharp edges, which point in the same direction, while the blade edges of the two sets point outwardly away from one another, generally in opposite directions. The edges of blade strips of the two sets may be arranged in one common working plane, or each set may be in its own working plane, with the planes at an angle to one another. The working planes are defined by the elongated front and rear guard surfaces of the blade-edge guarding system on the face of the razor head. These guard surfaces contact a user's skin before and after the razor-sharp edges to help ensure safe shaving.

  • Patent number: 5953824
    Abstract: Razors adapted to support a razor head during shaving while permitting the razor head to move relative to the razor in response to forces encountered during shaving. Preferred embodiments allow a razor head to swivel and also to pivot about an axis normal to a central axis of the razor and normal to an imaginary axis defined by the points of attachment of the razor to a razor head. According to another aspect, an engagement arm comprises a novel slot for controlling the movement of the engagement during shaving, as well as during loading/unloading of a razor head. Embodiments of this invention enable the razor head to maintain optimum shave relation with the skin regardless of the angular differences between the cartridge head, razor handle/grip and shaving motion during shaving.

  • Patent number: 5953825
    Abstract: In a safety razor, a blade assembly (2; 22; 52) is mounted to a handle by a mounting arrangement including several spring devices (8; 28: 68; 70) adapted so that the blade assembly is movable relative to the handle with several degrees of freedom, including pivotal movement about a longitudinal axis, pivotal movement about a transverse axis and translational movement in a downward direction substantially perpendicular to the plane defined by these axes. The longitudinal and transverse pivotal axes are not fixed in position and are variably located due to the spring suspension, allowing the blade assembly to follow closely the contours of a skin area being shaved.

  • Patent number: 5848475
    Abstract: The invention provides a razor having a retaining mechanism adapted to receive a blade longer than the mechanism for retaining the blade so that one or both wings of the blade extend past the retaining mechanism to provide a small straight razor. Additionally, the blade is positionable within the retaining mechanism so that its wing can be extended from one or the other side of the retaining mechanism. The retaining mechanism for the blade has a pivotably-attached handle to allow ergonomic adjustment of the shaving angle. The blade and retaining mechanism have associated mechanisms for retaining and aligning the blade in the retaining mechanism.

  • Patent number: 5787593
    Abstract: The present invention is directed to a razor comprising a handle, a razor blade unit having one or more razor blades which can be connected to the front end of the handle, and a connecting device for connecting the razor blade unit to the handle, such that the shaving results are improved for normal shaves as well as for specific applications like medical pre-operation shave. The razor blade unit of the present invention is mounted such that it can swivel relative to the handle about a swivel axis which intersects the cutting edge of the razor blade.
