Patent Application
20100071215
The present disclosure relates to a trimmer for a shaving razor. More particularly, the present disclosure has applicability to a trimmer for multi-blade shaving razors.
Heretofore, devices commonly used for removing facial hair have consisted of the “old fashioned” straight razor, the safety razor and the electric dry shaver. The safety razor, the most popular shaving implement, is especially adapted for the “clean shaven” look wherein facial hair is entirely removed. The principle of the safety razor is to place a guard between the skin and the cutting edge of a razor blade, so that the guard permits the cutting edge to pass over the surface to be shaved, removing the hair without cutting the skin. The safety razor is not satisfactory for grooming and shaping beards, moustaches and sideburns because the blade holder and guard obscure the cutting edge from the user's view and the configurations of the holder, guard and blade are not adapted for the shaping and trimming of the margins of beards, moustaches and sideburns. In addition, the guard makes it difficult to reach certain portions of the beard that are desired to be cut.
In order to overcome the above mentioned problems, the present disclosure provides a novel trimmer for a shaving razor. The trimmer comprises a blade having a cutting edge. In one embodiment, a plurality of teeth are located on one side of said blade at the cutting edge. On the side of the blade opposite the plurality of teeth are a plurality of ribs located at the cutting edge. In certain embodiments, each of the teeth are aligned with the ribs in a direction perpendicular to the longitudinal axis of the blade. Alternatively, the teeth and ribs are spaced alternating along the cutting edge of the blade. The number of teeth are equal to and alternatively, not equal to the number of ribs. Alternatively, the teeth are set on a platform.
In another embodiment, the blade has through holes, through which the ribs extend and interlock with the teeth. An outer edge of the ribs has a point with a tangent line parallel to the cutting plane of the trimmer that is aligned with the cutting plane of the trimmer. Alternatively, the tangent line is aligned behind or in ahead of the cutting plane of the trimmer.
The configuration of elements in the trimmers of the present disclosure provide safety against nicks and cuts without the necessity of a guard along the entire length of the blade. This prevents cut whiskers or hair from getting caught between the blade and other guard surfaces. The teeth and the ribs both reduce drag from surface friction by reducing the area of contact with skin at the point of use, thereby increasing comfort. Further, the varied spacing and alignment of the teeth and ribs allows for different degrees of comfort and protection.
Additional advantages and other features of the present disclosure will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from the practice of the disclosure. The advantages of the disclosure may be realized and obtained as particularly pointed out in the appended claims.
As will be realized, the present disclosure is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
Reference is made to the attached drawings, wherein elements having the same reference numeral designations represent like elements throughout, and wherein:
