Abstract: A rotating blade assembly provides a multiplicity of rotating blades for shaving. The rotating blades engage a surface, and create a multiplier effect for an enhanced shave. Multiple rotating blades minimize contact between each blade and the skin to extend the life of the blades, and also funnel hair and shaving cream away from the surface. A pair of gear assemblies inside the blade housing rotatably engages to provide smooth rotation for the blades. Openings in the blade housing create a space for the blades to extend out of, an opening for water to pass through during cleaning and usage, and an opening for the hair and shaving cream to pass through. A shaft locks the gear assembly to prevent rotation for more precise shaving of side burns, mustaches, and goatees. A hollow handle with an opening at the end allows residue to pass through during cleaning and usage.

Abstract: A self-powered razor head for shaving hair from a skin surface with at least one reciprocating blade with a roller with an annular skin engaging surface rotatably supported by a support case. In one embodiment, a first razor shuttle has first and second drive arms extending therefrom to travel oppositely in phase against a plurality of ridges and troughs of the roller to induce a reciprocation of the first razor shuttle and a first razor blade that is attached thereto in response to a rotation of the roller. A reciprocation of a second razor shuttle is generated by a pivoting drive lever that has a first end pivotally coupled to the first razor shuttle, a second end pivotally coupled to the second razor shuttle, and a fulcrum point therebetween. Instead of the second drive arm and the ridges and troughs against which it is disposed, the first drive arm may be biased to travel against the plurality of ridges and troughs of the first end of the roller by a resilient biasing member.

Abstract: A safety razor, comprises a handle element, a blade-carrying head element provided with at least one blade, a rotatable element having an axis and connected with the head element so as to rotate relative to the head element but jointly move in an axial direction, and a unit for imparting to the rotatable element a movement in the axial direction in response to contact of the rotatable element with a surface to be shaven, so that when user moves the handle element and therefore the head element in a predetermined direction during shaving, the rotatable element and therefore the head element of the blade is displaced in a direction which is tranverse to the predetermined direction in response to rotation of the rotary element, the imparting unit including a shaped grove provided in the rotary element and a spherical member arranged between the handle element and their rotatable element and movably engageable in the groove of the rotatable element.
