Description

TECHNICAL FIELD

The present disclosure relates in general to hand-held shavers and safety-razors with multiple razor-heads.

BACKGROUND

Recently, shaving has been predominantly accomplished by individuals using a traditional T-bar shaped shaver. The T-bar shaver generally comprises a single razor-head in which one or more blades are oriented perpendicular to an elongated handle forming a T-like shape. These shavers may be disposable after limited use or may have interchangeable razor-head cartridges that can be removed, disposed, and replaced. An example of this type of shaver is disclosed in U.S. Pat. No. 8,474,508. A shaver with a single razor-head is generally used for all shaving tasks regardless of the area of the body to be shaved. Although individual razor-heads come in differing sizes and configurations they are generally standardized and are usually of minimal size to accommodate finer, more detailed work such as the contours of the face and mouth.

Shavers with multiple razor-heads for various purposes are also known. Some shavers with multiple razor-heads are utilized to provide the ability to shave in two different directions and are referred to as bi-directional shavers. An example of this bi-directional shaver is disclosed in U.S. Pat. No. 6,141,875. Multi-headed shavers that are not simultaneously operable are further disclosed. These shavers usually include razor-heads of differing sizes and orientations in which the razor-heads face in opposing directions. These shavers may include a larger razor-head to efficiently accommodate larger shaving tasks for larger areas of the body and a smaller razor-head for more detailed shaving tasks in smaller areas of the body. An example of this type of razor is disclosed in U.S. Pat. No. 6,052,905. Multi-headed shavers that operate simultaneously have also been disclosed and make shaving large body parts such as the head or chest more efficient. An example of this type of shaver is disclosed in U.S. Pat. No. 9,701,033.

Shavers may be employed to remove or shorten hair on small or large areas of the body. Additionally, shaving may occur on curved areas of the body. Accordingly, it would be desirable to provide a shaver that efficiently accommodates shaving all areas of the body. Further, a shaver that accommodates shaving all areas of the body without interchanging, removing, or adding parts would be desirable.

A versatile multi-headed shaver comprising a plurality of razor-heads with a wide range of maneuverability could accommodate shaving tasks of various shapes and sizes. Such a shaver may also be able to accommodate shaving tasks of various shapes and sizes with minimal assembly or disassembly. The disclosed invention may accommodate some or all desirable features.

Alternatively, the pivotal joints 300 may be located at the connections between the arms 400 and the razor-heads 500. In some embodiments, the pivotal joints 300 may be within the arms 400. Some embodiments may include only a first plurality of pivotal joints 300 or a single pivotal joint 300 for each razor-head wherein each pivotal joint 300 allows each razor-head to rotate around two distinct axes-of-rotation. Some embodiments may include pivotal joints 300 that allow rotation around more than two distinct axes-of-rotation. Alternatively, some embodiments may include more than a first and second plurality of pivotal joints 300. For example, some embodiments may employ a single pivotal joint, two pivotal joints, three pivotal joints or more to allow rotations around three or more axes-of-rotation. Some embodiments may have pivotal joints 300 located in different locations for different razor-heads 500. For example, one embodiment may include three razor-heads 500, wherein the center razor-head 500 has a pivotal joint 300 located at the connection between the razor-head 500 and the arm 400 while the peripheral razor-heads 500 have pivotal joints 300 located at the connections between the arms 400 and the handle 200.

Some embodiments may require detaching parts and reattaching parts in new positions around an axis-of-rotation to lock the position. Alternatively, displacement may be used to disengage and engage restrictive elements. For example, in FIG. 1, the interior of the proximal portion of each hollow cylindrical receptacle 304 could be splined and the round shaft portion 402 of each arm 400 could be splined. In embodiments with splined portions, rotation of the arms 400 would be restricted when fully disposed in the hollow cylindrical receptacle 304 but allow the user to rotate the arms 400 when displaced in the distal direction. Alternatively, teeth located at the connection between the round shaft portion 402 of each arm 400 and the downward sloping portion 404 of each arm 400 could be engaged and disengaged with teeth located at the most distal portion of the hollow cylindrical receptacle 304. In embodiment with teeth at strategic locations the restrictive element could be disengaged by moving the arm in the distal direction and engaged by moving the arm in the proximal direction. In some embodiments the displacement could be manual. Alternatively, the displacement could be assisted by an elastomer, in what is known to one skilled in the art as elastomeric displacement. In elastomeric displacement an elastomeric material is attached to a portion of each adjacent part. The elastomeric material when at rest engages the restrictive element locking the position of the pivotal joint, however when stressed, either by pushing or pulling the adjacent parts, the elastomeric material is stretched so the restrictive element can be disengaged and the adjacent parts can be rotated. After releasing the adjacent parts, the elastomeric material returns to its rest position engaging the restrictive elements and locking the position. Some embodiments may include a combination thereof.

If an elastomeric material is included it may be composed of polyisoprene, polybutadiene, ethylene propylene diene, nitrile butadiene, urethanes, rubbers or any other suitable material known to one skilled in the art. In some embodiments, the pivotal joints 300 may alternatively be composed of acrylonitrile butadiene styrene, polystyrene, polyethylene, polyurethane, polycarbonate, polyester, polyethylene terephthalate, polyvinyl chloride, any vinyl material, acrylic, polyacrylate, or any other polymeric material. Some embodiments may include thermoplastic or thermosetting polymers. The pivotal joint 300 may also be composed of metal, wood or any other suitable material known to one skilled in the art. Some embodiments may include pivotal joint 300 composed of multiple materials. For example, the rivets 302 may be composed of stainless steel or plastic-coated aluminum and the remaining portion of the pivotal joints may be composed of polypropylene.

Some embodiments may further contain a light for illuminating the skin. An example of a shaver containing a light is disclosed in U.S. Pat. No. 4,094,062 and incorporated by reference in its entirety. The light may include an incandescent or luminescent lamp such as a light emitting diode (LED) bulb. In some embodiments, the light will be located at the distal portion of the shaver 100. Embodiments with a light should have a power source such a battery or multiple batteries. In some embodiments, the power source may use one or more rechargeable batteries. In some embodiments, the power source may use one or more disposable batteries. In some embodiments, the power source may be located within the handle 200. The power source and connecting wires may be covered and sealed to prevent water damage. Examples of a power source located in the handle are disclosed in U.S. Pat. Nos. 5,007,169, 8,683,701, U.S. Patent Publication No. 2010/0313425 and incorporated by reference in their entirety.
