1. Field of the Invention
This invention pertains to disposable razors, and more particularly to disposable razors designed to safely cut whiskers or hairs on the skin when moving the razor head back and forth over the skin in opposite direction.
2. Description of the Related Art
Disposable razors are very popular because they are relatively inexpensive and provide a reasonably close shave. Typically, disposable razors include two to five parallel blades mounted longitudinally inside the razor head. All of the blades are diagonally aligned in the same direction so that the blade's cutting edges and cuts whiskers or hairs when the razor head is pulled over the skin.
The razor head is perpendicularly aligned on the distal end of a rigid handle. On some razors, the razor head is able to rotate 20 to 30 degrees over the end of the handle allowing it to swivel and closely conform to the skin.
One drawback with using disposable razors is that the razor head must be lifted and re-positioned on the skin at the end of each stroke. If the razor head is lifted and not re-positioned properly on the skin, the blades may cut the skin. Re-positioning the razor head properly on the skin to prevent cuts is especially problematic for men when shaving around the chin and jaw and for woman when shaving their legs.
It is well known that facial whiskers and leg hair grows at different angles and that moving the razor head back and forth in different directions over the skin provides a closer shave than does moving the razor in one direction. Unfortunately, in order to move typical razors back and forth over the skin, the razor head must be lifted and re-positioned on the skin, thus increasing the opportunities for cuts.
What is needed is a disposable razor that enables the razor head to be moved back and forth over the skin for a closer shave that does not require the head to be lifted and re-positioned on the skin.
The above objects are met by the disposable razor disclosed herein that includes a razor head with two sets of inward, opposite slanted blades mounted transversely therein. The cutting edges of the blades extend through an opening formed on the front surface of the razor head. The razor head is pivotally mounted on the distal end of a handle which allows the razor head to swivel over the skin while maintaining contact with the skin as the handle is rotated above or below the razor head. By merely rotating the handle over the razor head, the razor can be used in a back and forth motions over the skin forcing a close shave. In the preferred embodiment, the front surface of the razor head and the longitudinal axis of the handle are approximately 20 degrees apart. In one embodiment, the handle is able to rotate approximately 20 to 140 degrees over the back surface of the razor head. In another embodiment, the handle is fixed on the razor head. Each set of blades includes 2 to 4 individual blades. The blades in each set are spaced apart approximately 1/64 of inch and are diagonally aligned approximately 45 degrees from the razor head's front surface. The two sets of blades are equally aligned on opposite sides of the head's center longitudinal axis. Stop surfaces are provided between the head and the handle so that the blades are properly positioned for cutting when the handle is rotated to a full downward or upward position.
An optional flexible swipe blade is attached to the upper back edge of the razor head that allows the user to wipe away excess shaving cream or gel from the skin.
Referring to the accompanying
Disposed between the razor head 15 and the handle 42 is a joint 30 that allows the handle 42 to rotate between a downward diagonal position shown in
In the first embodiment, the two sets of blades 20, 22 and 24, 26 are equally aligned on opposite sides of the head's 15 center longitudinal axis 16. Stop surfaces 62, 64 are provided between the head 15 and the bushing 50 so that the blades 20, 22 and 24, 26 are properly positioned when pulling the handle 42 in opposite directions over the skin 90.
An optional flexible swipe blade 70 is attached to the upper back edge of the razor head 15 that allows the user to wipe away excess shaving cream or gel.
As shown in
In both embodiments, each set of blades includes 2 to 4 individual blades. The blades in each set are spaced apart approximately 1/64 of inch and are diagonally aligned approximately 45 degrees from the razor head's front surface
In compliance with the statute, the invention described herein has been described in language more or less specific as to structural features. It should be understood however, that the invention is not limited to the specific features shown, since the means and construction shown, is comprised only of the preferred embodiments for putting the invention into effect. The invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted in accordance with the doctrine of equivalents.
