Patent Application
20110016722
This application relates generally to hair trimming or shaving devices and more particularly to an improved razor system.
Shaving, or otherwise trimming hair, frequently involves approaching hair from a variety of awkward angles and passing a razor, or other hair cutting implement, over an uneven skin surface. Thus, shaving, or otherwise trimming hair, can often lead to nicks, cuts and scratches on one's skin. Therefore, it would be beneficial to have the capability to easily approach the hair from a variety of angles, trim hair protruding from a variety of uneven surfaces, while also protecting the skin against nicks, cuts and/or scratches.
In particular, this application discloses a razor system comprising a cage comprising a plurality of arcuate members, wherein the arcuate members are separated by adjacent openings, each opening operable to receive hair for trimming; a rotatable shaft extending into the cage; and one or more blades coupled to the rotatable shaft, each blade operable to trim hair received by each opening of the cage.
This application also discloses a method for trimming hair comprising: rotating at lease one blade within a cage, wherein the cage comprises a plurality of arcuate members, wherein the arcuate members are separated by adjacent openings, each opening operable to receive hair for trimming; and placing the cage against hair for trimming, wherein at least a portion of hair enters at least one opening to be trimmed by the blade.
This application further discloses a razor system comprising: a substantially spherical cage comprising a plurality of arcuate members, wherein the arcuate members are separated by adjacent openings, each opening operable to receive hair for trimming; a rotatable shaft extending into the cage; one or more blades coupled to the rotatable shaft, each blade operable to trim hair received by each opening of the cage; and a motor for rotating the rotatable shaft.
The drawings, when considered in connection with the following description, are presented for the purpose of facilitating an understanding of the subject matter sought to be protected.
Referring now to
The rotatable shaft 104 extends from a handle or casing 120 into the cage 102. The distal end 122 of the shaft 104 may be rotatably coupled to the top portion 112 of the cage 102. As will be discussed further below, the shaft 104 is operable to rotate relative to the cage 102 and provide a hair cutting motion to the blade(s) 106 coupled thereto. The shaft 104 may be rotated by any suitable means, including, but not limited to, manually, via an electric motor, etc. In one embodiment, the shaft 104 is rotated by an electric motor that is encased, along with one or more batteries, in the casing 120.
One or more blades 106 is coupled to the shaft 104. The blade(s) 106 may be coupled to the shaft by any suitable means, including, but not limited to, mechanical fasteners, adhesive, bonding, welding, etc. In one embodiment, at least one edge 124 of each blade 106 is beveled and/or sharpened such that the blade 106 may cut hair. Also, in one embodiment, one or more blades 106 may be arcuate in shape. As shown in
Also, as shown in
The system 100 may optionally include one or more guard bars 128 that intersect, or are otherwise coupled to, one or more cage arcuate members 108 such that the guard bars 128 extend between one or more openings 110 so as to limit the size of objects that may pass through the opening(s) 110 into the interior chamber of the cage 102. The guard bars 128 may extend between the edges 116 of adjacent arcuate members 108. Alternatively, the guard bars 128 may overlay the exterior surface 130 of one or more arcuate members 108. In one non-limiting example, the guard bars 128 may be rings that are placed about the cage 102 and engage the outer surfaces 130 of one or more arcuate members 108. The guard bars 128 may be integral with one or more arcuate members 108. Alternatively, one or more guard bars 128 may be coupled to one or more arcuate members via any suitable means, including, but not limited to, mechanical fasteners, welding, adhesive, bonding, etc.
In operation, the cage 102 is placed against skin so that at least a portion of hair protruding from the skin may enter into the cage 102 via the openings 110. The blades 106 are rotated within the cage 102 by rotation of the shaft 104. As the blades 106 rotate, the blades 106 cut the hair that has extended into the cage via the opening(s) 110. Advantageously, a cage 102 comprising arcuately shaped members 108 permits a user to trim hair from a variety of different angles and similarly configured blades 106 may further assist the efficiency such a shaped cage 102 may provide. Other geometrically shaped cages and/or blades may also provide similar advantages and efficiency.
While the present disclosure has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this disclosure is not limited to the disclosed embodiments, but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
