Abstract
A shaving razor comprises a finger grip consisting of a body having contoured sides, a top surface and a base. A razor head is affixed to the top surface. The finger grip sides are concave in shape to conform to and accommodate the shape of the user's fingers. When the finger grip is held between the user's fingers and the razor head is placed against the skin, the user's fingers are capable of contacting the skin adjacent to the razor head to provide sensory feed back to the user. The razor head is adapted to contain one or more blades, or pairs of blades, extending in a single direction for unidirectional shaving; or alternatively, the head may contain more than one blade, or pairs of blades, extending in opposite directions for bi-directional shaving. In different embodiments, the finger grip razor may be fitted with non-replaceable blades and is disposable or the razor grip may be fitted with replaceable blades and is reusable. In different embodiments, the head and/or the blades on the head are pivotally mounted with respect to the finger grip. In another embodiment, a razor head is affixed at each end of the finger grip. The design of the razor grip permits safe unidirectional shaving using a conventional pull shaving stroke, and safe bi-directional shaving using both pull and push cut strokes. A shaving substance may be stored within the finger grip to be selectively dispensed directly to the razor head and onto the user's skin during shaving. In another embodiment, a bar of shaving substance is affixed to the base of the finger grip.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a method for shaving hair and to apparatus consisting of unidirectional and bi-directional razors useful to practice that method. In particular, the present invention relates to a method for shaving body parts in which a finger grip razor is contoured to be held between the user's fingers in such a manner that the user's fingers are capable of continuous or selective contact with the user's skin during the shaving strokes; and to apparatus comprising a finger grip razor contoured to conform to the shape of the user's fingers so that the method of the present invention can be practiced.
2. Information Disclosure Statement
Razors capable of shaving hair off of parts of the body are well-known. Typically, a razor consists of an elongated handle designed to be held in the hand between the thumb and forefinger of the user, and having a razor head with one or more transversely extending blades affixed at one end of the handle. The prior art includes razors in which pairs of blades extend in one direction to permit shaving only in one direction, and also includes razors in which pairs of blades extend in opposite directions whereby the user may move the razor head in one direction for contacting one pair of blades against the use's skin for cutting hair and then, without lifting the razor head from the skin, move the handle in the opposite direction so that the other pair of blades cuts hair during the reverse movement of the razor. The prior art also includes finger-mounted razors in which blade-holding razor heads are mounted on rings which slide over the user's fingers.
A preliminary patentability search produced the following patents, which may be relevant to the present invention: Lishawa, U.S. Pat. No. 1,201,317, issued Oct. 17, 1916; Brown, U.S. Pat.

No. 6,112,421, issued Sep. 5, 2000.
However, none of the known prior art razors teach the use of a shaving method and apparatus utilizing a finger grip razor that is sized and contoured to snugly and comfortable fit between fingers of the user's hand so as to permit the user's fingers to contact the shaved surface, thereby allowing safe bi-directional shaving using reciprocating pull and push cut strokes without having to lift the razor from the user's skin and without having to worry about orienting the finger grip and/or razor head at a critical or safe angle with respect to the user's skin surface.
The known prior art devices do not teach either the method or apparatus or the present invention and do not provide the benefits of utility, safety, control, efficiency and economy that are inherent in the method and apparatus of the different embodiments of the finger grip razor of the present invention. Neither the finger-mounted nor conventional elongated handle razors of the prior art provide the safety or control that is obtainable with the finger razor of the present invention, particularly when shaving parts of the body that are difficult to reach and/or not visible.
None of the known prior references, either singly or in combination, disclose or suggest the present invention.
It is therefore desirable to provide a method of shaving wherein a finger grip razor is contoured to fit between the user's fingers and permits the user's fingers to contact the surface being shaved for the safe and efficient shaving of both visible and out-of-sight body parts, and contoured parts, and a razor apparatus capable of performing that method.
BRIEF SUMMARY OF THE INVENTION
The present invention comprises apparatus for and a method of shaving in which a finger grip razor is contoured to fit between and to receive and cradle the user's fingers whereby both the razor head and the user's fingers are capable of contact with the user's skin during the shaving strokes so that the user can determine the closeness of the shave so far obtained and also obtain sensory feedback as to whether or how the contour of the shaved surface is changing and as to whether additional shaving of the area is necessary or desirable. The combination of the between-finger contoured design of the finger grip razor, and the capacity of the fingers to touch the skin, permits extremely close motion and pressure control of the razor, particularly on difficult-to-reach body parts that can not be seen and/or where the body contour changes sharply or frequently. The finger grip razor has two opposed sides that are contoured to have generally concave shapes to fit snugly and comfortably between the generally convex shapes of the user's fingers. A razor head is affixed at the end of the finger grip between the two contoured sides. The razor head may contain a single or multiple blades for unidirectional shaving or a single or multiple pairs of blades extending in opposite directions for bi-directional shaving. The finger grip razor may be disposable or the razor head may contain replaceable blades or cartridges, whereby the finger grip and/or head are made reusable by the feature of changeable blades. The design of the razor is such that when the razor head contacts the user's skin during a shaving stroke, the user's fingers are capable of contacting the skin adjacent the area being shaved, thereby enabling the user to detect and adjust for any changing contour of the body, and to sense whether uncut hair remains and, if so, to determine the proper shaving motion and direction and to apply the necessary amount of pressure to obtain a safe shave having the desired closeness.
It is an object of the present invention to provide a shaving method and apparatus comprising a finger grip razor having opposed generally concave sides that are contoured to fit between the generally convex shapes of the user's fingers and to cradle the user's fingers to provide for an enhanced degree of motion control over the razor and the shaving stroke.
It is another object of the present invention to provide a razor capable of either unidirectional or bi-directional shaving.
It is another object of the present invention to provide a razor that permits simultaneous contact between the user's fingers and the shaved surface during shaving to provide sensory feedback regarding the necessity or desirability of additional shaving strokes.
It is another object of the present invention to provide a razor that is capable of safe and easy manipulation on difficult-to-reach body parts, particularly body parts that are not visible.
It is another object of the present invention to provide a razor that provides enhanced capacity to shave body parts where the contour of the body changes sharply, such as those parts of the face around and under the chin, nose, and jaw.
It is another object of the present invention to provide a razor which may be disposable or may be reusable through the feature of a replaceable head or replaceable blades on the head.
It is another object of the present invention to provide a razor having the feature of pivoting blades.
It is another object of the present invention to provide a razor having a blade or multiple pairs of blades aligned in only one direction, or having a blade or multiple pairs of blades aligned in opposite directions.

DETAILED DESCRIPTION OF THE INVENTION
In describing the embodiments of the invention by reference to the several figures of the drawings, the same reference numerals are used to designate the same elements appearing in the several embodiments of the invention. Also, referring to the drawings, it will be seen that each embodiment of the finger grip razor the present invention is symmetrical about its vertical centerline.
Referring to
FIGS. 1-3
, one embodiment of the present invention comprises a finger grip razor indicated generally by the numeral
10
, having a finger grip body indicated generally by the numeral
20
, and a razor head indicated generally by the numeral
30
(FIG.
4
). The finger grip body
20
has a foot or base
22
, ends
24
, opposing contoured sides or necks
26
and a top surface
28
. The top surface
28
has a slight inward and upward pitch as illustrated to provide a pitch to the blades mounted thereon. Alteratively, the inward and upward pitch to the blades may be provided by the design of the razor head
30
or by the blade cartridges received by the head
30
. The head
30
is mounted on the top surface
28
of finger grip
20
between the two contoured sides
26
and has a first pair of blades
32
facing in one direction and a second pair of blades
34
facing in the opposite direction, whereby the razor is useful for both unidirectional shaving using a pull or draw shaving stroke and for bi-directional shaving using alternating draw and push shaving strokes. In the embodiment illustrated in
FIGS. 1-3
, the razor head
30
and blades
32
and
34
mounted thereon are aligned substantially parallel to the contoured sides
26
of the finger grip
20
. A bar
23
of a substance suitable for shaving such as soap may be affixed to the bottom of the base
22
.
Experimentation has shown that, because of the inherent compatibility and receptivity between the generally concave shape of the finger grip sides
26
and the generally convex sides of the user's fingers, literally one size of the finger grip invention fits all users. Nevertheless, it will be appreciated that the present invention may be constructed in different sizes. The dimensional proportions of the finger grip
20
should be such that the concave sides
26
will receive in cradle-like fashion the sides of the fingers of the user and, when the razor head
30
is placed against the skin, the leading finger, i.e., the finger in advance of the razor head
30
with respect to the direction of travel of the razor head, will be capable of contacting the skin in advance of the razor head
30
during the shaving stroke. Prototype models having dimensions of approximately one (1″) inch in height (measured from base
22
to top surface
28
), widths of three-fourths (¾″) inch for the base
22
and top surface
28
, and a length of one and three-fourths (1¾″) inches for the base
22
and top surface
28
, have been found to function satisfactorily and to provide all of the useful benefits described herein.
Referring to
FIGS. 7-9
, another embodiment of the present invention is disclosed in which the blades
32
and
34
mounted on the razor head are aligned substantially transversely to the contoured sides
26
of the finger grip
20
. All of the descriptions and disclosures made in connection with the construction and features of the embodiment illustrated in
FIGS. 1-3
apply to the embodiment shown in
FIGS. 7-9
. The only difference between the embodiments disclosed in
FIGS. 1-3
and
FIGS. 7-9
is the alignment or orientation of the blades with respect to the contoured sides
26
of the finger grip
20
and the fingers holding the finger grip razor. The method of using the different embodiments shown in
FIGS. 1-3
and
FIGS. 7-9
is the same.
The preferred technique for shaving with the present invention, as illustrated in
FIGS. 10-11
, is to hold the finger grip
20
between two adjacent fingers, such as the index and middle fingers. However, it will be appreciated by those skilled in the art that the finger grip razors disclosed herein are capable of producing the benefits described when held between any two fingers, such as, for example, the thumb and the middle finger.
The finger grip
20
may be a permanent finger grip provided with a replaceable head
30
, or replaceable blades on the head, or the finger grip
20
and head
30
may comprise an integral, disposable unit. Finger grip
20
may be made of metal, plastic, ceramics, rubber, wood, or any combination of such materials, suitable to withstand the uses, handling and environment to which wet shaving razors are customarily exposed. The contoured sides
26
may be constructed of a softer pliable material for comfort and may have a textured surface to provide a non-slip grip.
The finger grip
20
may be constructed in whole or in part of a pliable material and provided with a hollow interior (
FIG. 6
) to provide a shaving substance storage chamber
50
for storing a supply of lubricating or shaving substance such as shaving cream, lotion, shaving gel or other lubricating substance therein. During use, lubricating substance stored in chamber
50
may be dispensed onto the head and user's skin by the application of a squeezing force on the finger grip sides
26
during use.
It will be appreciated by those skilled in the art of shaving apparatus, that head
30
may have one or more blades oriented for unidirectional shaving, or may have a plurality of pairs of blades oriented in opposite directions to permit bi-directional shaving. The head
30
may be permanently affixed to finger grip
20
or, alternatively, head
30
may be releaseably mounted on top
28
of the finger grip
20
such as by well-known spring loaded clips (not shown) used to releasably mount blade cartridges on conventional razors. When head
30
is integrally affixed to finger grip
20
, the blades
32
and
34
may be releasably mounted thereon such as by spring loaded clips or other well-known techniques to provide a replaceable razor, or the blades
32
and
34
may be non-replaceable to provide a disposable razor. Alternatively, the head
30
itself may comprise blade cartridge units that are either releasable affixed directly to the top
28
of finger grip
20
such as by spring loaded clips or other well-known techniques to provide a replaceable blade feature, or blade cartridge units may be permanently affixed atop finger grip
20
, whereby the razor
10
will be a disposable unit. Also, as discussed below, the head
30
and/or the blade cartridge units may be pivotally mounted on head
30
or immovably affixed to top surface
28
.
It will be appreciated by those skilled in the art that means such as a plurality of paths or water ways may be provided to purge the razor of shaving debris by flushing the razor with water, thereby preventing the clogging of the head with shaved debris. Such water ways may consist of channels or grooves in the top surface
28
, or the razor head
30
or disposable blade cartridges used with head
30
may have such paths constructed therein.
Referring to
FIG. 4
, an exploded view of the finger grip razor of the present invention illustrates a latching means useful to removably connect the razor head
30
to the razor finger grip
20
in either a pivoting or non-pivoting relationship. A latching means for attaching head
30
to finger grip
20
is a mechanism indicated generally by the reference
40
consisting of a longitudinal, cylindrical groove
42
in finger grip top surface
28
that extends the full length of razor finger grip
20
and a cylindrical shaped tongue
44
that extends along the full length of the bottom of razor head
30
. The groove
42
is designed and sized to receive and retain the tongue
44
in a sliding relationship. The mechanism
40
provides both a latching means for affixing razor head
30
to razor finger grip
20
and a means for allowing razor head
30
and the blades thereon to pivot with respect to finger grip
20
. By constructing the groove
42
and cylindrical tongue
44
so that no gap appears at the interface of the bottom surface
31
of head
30
and the top surface
28
of finger grip
20
, the head
30
will not pivot with respect to finger grip
20
. By modifying the dimensions of the groove
42
with respect to the dimensions of the cylindrical tongue
44
, a gap may be made to occur at the interface of the bottom surface
31
of head
30
and the top surface
28
of finger grip
20
, whereby the head
30
will pivot with respect to finger grip
20
. The latching mechanism
40
makes the head
30
and blades thereon removable and replaceable with respect to the finger grip
20
. It will be apparent to those skilled in the art that other means for permitting head
30
and/or the blades thereon to pivot with respect to finger grip
20
are within the scope of the present invention.
In the embodiment shown in
FIG. 5
, the finger grip
20
has a razor head
30
with blades
32
and
34
mounted at both ends thereof to provide a razor having a shaving capacity at either end. It will be appreciated that all of the features previously disclosed with respect to the other embodiments such as replaceable blades, unidirectional and bi-directional blades, pivoting and non-pivoting blades are all applicable to the dual ended razor shown in FIG.
5
. This dual ended razor will be seen to provide a particular benefit of economy when featured in a disposable razor because of the double shaving capacity provided by the additional blades. While the dual ended razor shown in
FIG. 5
has the head
30
and blades thereon aligned substantially parallel to the contoured sides of finger grip
20
, it will be recognized that it will be possible to make a dual ended finger grip razor in which the head
30
and blades thereon are aligned substantially perpendicular or transversely to the contoured sides
26
of finger grip
20
.
It will be appreciated by those skilled in the art that all of the embodiments of the present invention may be provided with a clip-on protective safety cover for the razor head
30
to protect against cuts when the razor is not in use.
In the embodiment shown in
FIG. 6
, the finger grip
20
is hollow and contains a chamber, indicated by the dotted line
50
, to provide for the storage of a lubricating shaving substance such as shaving cream or shaving gel therein. A removable plug
52
in the base
22
of finger grip
20
permits the shaving substance storage chamber
50
to be filled with a shaving substance and allows the dispensing of that shaving substance as needed for shaving. A plurality of holes
29
in the top surface
28
of finger grip
20
(
FIGS. 4 and 6
) may be provided to allow the selective dispensing of the shaving substance directly into the razor head
30
and onto the skin during shaving.
In use, the finger grip
20
will be held between two fingers, such as the forefinger and the middle finger, and the razor head
30
may be positioned on either the palm side of the fingers as shown in
FIG. 10
or the backhand side of the fingers as shown in FIG.
11
. The head
30
will then be placed against the skin and the edge of the finger on the leading side of the finger grip
20
will touch the skin in advance of the head
30
. The user will then move the head
30
along the skin using a pull stroke, or the user may move the head
30
along the skin using alternating pull strokes and push strokes without removing the head from its shaving position against the user's skin. During the shaving strokes, the contact between the user's leading finger and skin permits the user to control the razor with respect to the pressure being applied to determine the closeness of the shave, and to manipulate the razor at places where the contour of the surface being shaved changes shape and contour sharply or frequently to provide for a safe shave. During the shaving strokes, the user may selectively apply shaving substance directly to the skin by squeezing the finger grip
20
to dispense the shaving substance contained therein. If the embodiment having the shaving bar affixed to the base
22
is being used, the user will moisten the skin and rub the bar against to skin to apply the shaving substance as needed.
Although the present invention has been disclosed and illustrated with respect to specific embodiments and a preferred use for such embodiments, it is not to be so limited since modifications and changes can be made therein which are within the full intended scope of the invention.
