Description

FIELD OF THE INVENTION

The present invention relates to hair styling scissors to aid hair stylists in cutting and styling hair in a more efficient manner and a removable and tapered razor. The present invention also relates to a tapered razor assembly.

BACKGROUND OF THE INVENTION

For many hair stylists, success comes not only from the quality of the work, but also from the speed at which they provide their service. The more customers a stylist or hairdresser can service in a given day, the more revenue they can earn. However, the introduction of new technology has caused hair styles to become more complex, requiring stylists to become familiar with new technologies to accommodate any requested style. This creates a problem. For a stylist to be successful, he or she must learn how to use these tools in the most efficient way possible.

One tool that has become more and more popular over the years is the feather razor. A feather razor is used to give hair more volume. It does so by layering the hair and taking away unwanted weight in the hair so that it does not lay flat to the head. Almost every hair stylist has a feather razor and uses it regularly. Depending on the style of haircut requested, the hair stylist may have to switch between his or her scissors and the feather razor countless times throughout the cut. Switching back and forth, while trying to maintain efficiency, can cause injuries to the stylist and the customer, and add unnecessary time to the service, necessarily reducing the potential revenue a stylist can earn during a single work-day.

In U.S. Pat. No. 4,805,305 a combination razor and scissor device is disclosed. A first jaw of pair of scissors comprises a recess for securing a razor. This combination device eliminates the need for a stylist to have a separate razor and pair of scissors. A problem with this particular device, however, is that the razor cartridge is inserted proximate the sharp point of the blades, risking injury. Another problem with this prior art device is that a stylist can only use the razor of the device with the scissors in an open position, which further increases the risk of injury.

Hair trimming razors are known in the art. These razors have finger rings on the rear or other portions of the handle as disclosed in U.S. Pat. No. 6,092,288. A problem with this particular device, however, is that the razor cartridge is inserted proximate the sharp point of the blades, risking injury.

U.S. Published Patent Application No. 2007/0209214 discloses a combination hair tool that comprises a scissor and a razor. The combination hair tool comprises two scissor blade portions operatively arranged to be pivotably connected, wherein one of the scissor blade portions includes a fixedly secured razorblade holder including a blade holder slot, a handle portion, and a finger ring. The combination tool razor blade scissor portion accepts a slidably secured razor blade from the opposite end of the finger ring towards the pivoting connection. A problem with this particular device, however, is that the razor cartridge is inserted proximate the sharp point of the blades, risking injury.

Another issue pertains to a removable razor disposed within a slot within a scissor's blade member. Traditional feather razors have a substantially rectangular arrangement, such that the traditional feather razor creates a distance between the side opposite of the scissor's blade and the sharp edge of the razor—creating a potential snag point that could introduce unnecessary injury and/or risk, while potentially slowing down a hairstylist during a haircut.

Thus, there is a long felt need for a pair of scissors with a removable feather razor that allows a hair stylist to cut hair with scissors and style hair with a feather razor in a single tool, safely securing the razor, while allowing a stylist to adjust a rotatably secured finger loop.

There is also a long-felt need for a pair of scissors with a removable feather razor held in a cartridge, which cartridge is installable into the scissor blade from the finger ring part of the scissors.

There is an additional long felt need for a pair of scissors with a removable feather razor where the removable razor is tapered, such that the tip of the removable feather razor seamless transitions into the opposite side of a scissor's blade.

Further, there is yet another long felt need for a pair of scissors with a tapered removable feather razor that is arranged to be inserted into a slot disposed on the opposite side of the scissor's blade, where the slot is closed proximate to the tip of the scissor's blade and the slot is open proximate to the handle of the scissor.

Even further there is a long felt need for a razor blade assembly having a tapered razor blade secured adjacently to at least one guard member having a respective tapered configuration.

SUMMARY OF THE INVENTION

The present invention broadly comprises a scissors with removable feather razor, comprising a static blade member having a blade portion, said blade portion having a tip at a first end and a handle portion at a second end, wherein said blade portion has a cutting edge and a back edge and said handle portion has a static neck portion and a static finger ring extending therefrom, said static blade member also having an aperture to accommodate a tension screw, said aperture located between said first end and said second end, and closer to said first end than said second end, said blade portion having a slot therein, said slot closed proximate said tip portion, said slot arranged parallel to said cutting edge of said static blade member, said slot arranged to extend leftwardly and rightwardly of said aperture; a dynamic blade member having a blade portion, said blade portion having a tip at a first end and a handle portion at a second end, wherein said blade portion has a cutting edge and a back edge and said handle portion has a dynamic neck portion and a dynamic finger ring extending therefrom, said dynamic blade member also having an aperture to accommodate said tension screw, said aperture located between said first end and said second end, and closer to said first end than said second end; and, a tension screw operatively arranged to pass through both said static blade aperture and said dynamic blade aperture to hold said static blade member and said dynamic blade member in close proximity to one another and form a pivot point about which both said static blade member and said dynamic blade member are operatively arranged to pivot relative to one another.

The present invention also generally includes a tapered razor assembly. The tapered razor assembly includes a tapered razor assembly arranged to be removably inserted into a slot disposed on a static blade member of a scissors. The tapered razor assembly includes a razor blade having a base extending from a back end to a tip end, the razor blade having a pair of side surfaces extending from the base, the pair of side surfaces arranged to terminate at a cutting edge, the cutting edge tapering from the base end to the tip end, a guard member fixedly secured to one of the pair of the surfaces, the guard having a guard end, a base, and a tip, and a cover member fixedly secured to one of the pair of side surfaces, the cover having a base and a tip, wherein the guard member and the cover member sandwich the razor blade.

The tapered razor assembly of the present invention also generally comprises a guard and an outer cover arranged to fixedly sandwich the tapered razor therebetween, the guard comprises a guard end and a base end, the guard end having a substantially sinusoidal outer edge configuration, where both the guard and the cover have a tapered configuration.

A general object of the invention is to provide an adjustable and removeable blade and scissor device that allows a stylist to use a feather razor and scissor simultaneously.

A secondary object of the invention is to provide a pair of scissors with a removeable razor blade, which blade is held in a cartridge, and which cartridge is insertable into one of the blades of the scissors from the end of the scissors closest to the finger rings.

A further object of the invention is to provide a combination scissors/feather razor blade assembly wherein the pair of scissors includes a pivot point about which the pair of scissor blades pivot, and wherein a cartridge containing the feather razor overlaps or straddles the pivot point to achieve an optimally balanced pair of scissors.

Another object of the invention is to provide a combination scissors/feather razor blade assembly is to provide for a tapered feather razor within a removable razor cartridge (i.e., tapered razor assembly), where the tapered razor assembly includes a dovetail arranged to abut and rest on a back side of a blade member of the scissors, where the dovetail includes a tip arranged to extend past a tip end of the tapered feather razor.

An even further objection of the invention is to provide a combination scissors/feather razor blade having a tapered feather razor within a removable tapered razor assembly, where the tapered razor assembly includes a dovetail extending therefrom to eliminate a snag point that traditional, substantially rectangular-shaped, feather razors create when inserted into the removable razor cartridge.

These and other objects of the invention will become apparent upon review of the following detailed description of the invention in view of the drawings and appended claims.

As described supra, handle portion 82 is defined by the components that engage fingers 101, 102, and 103 of right hand 100, as shown in FIG. 2. Removable razor cartridge 16 is arranged to be slid into slot 50 from open end 52 in the direction towards closed end 51, engaging slot 50 as illustrated in FIG. 7B. This configuration eliminates the risk of injury related to a razor cartridge being inserted proximate a sharp tip of a blade member.

To use removable razor 16, scissor razor combination 10 is moved to a closed position shown in FIGS. 5 and 6. A user would comb a section or layer of hair and pull removable razor 16 up or down that section or layer to create a textured or feathered look.

Tapered Razor Assembly & Scissor/Tapered-Razor Combination

Adverting now to the scissors with a removable and tapered feather razor of the present invention, scissor/tapered-razor combination 10′. It should be noted that only the differences between scissor/tapered-razor combination 10′ and scissor/razor combination 10 include tapered razor assembly 100 compared to removable razor cartridge 16 and slot 50′ compared to slot 50. Notably, the configuration of tapered razor assembly 100 of scissor/tapered-razor combination 10′ removes snag point SP, created by scissor tip end 16A of removable razor cartridge 16 and back edge 84 of scissor/razor combination 10, as shown in FIG. 2.

The following description should be taken in view of FIGS. 12 through 15, which generally illustrate: a left side view in an open configuration; a right side view in an open configuration; a left front perspective view in an open configuration; a right front perspective view in an open configuration; and, a right front perspective view in a closed configuration, of scissor/tapered-razor combination 10′, respectively. Scissor/tapered-razor combination 10′ notably includes tapered razor assembly 100 which generally includes dovetail 105 extending from two respective sides and tip 106 of dovetail. Dovetail 105 of tapered razor assembly 100 is arranged to rest on back edge 84 of static blade member 11 when tapered razor assembly 100 is disposed within slot 50′ (shown in FIGS. 18A and 18B).

Tapered razor assembly 100 is preferably arranged to have tip end 101A and back end 101B. Tapered razor assembly 100 generally includes guard 102, cover 103, and tapered razor 104 secured therebetween. Guard 102 comprises base 102A, guard end 102B, external surface 102C, and internal surface 102D. Cover 103 comprises base 103A, external surface 102B, and internal surface 103C. Tapered razor 104 comprises cutting edge 104A, base 104B, first surface 104C, second surface 104D, tip end 104E, and back end 104F. Guard 102 also includes dovetail 105A extending from external surface 102C. Dovetail 105A includes tip 106A having internal surface 106C. Cover 103 also includes dovetail 105B extending from external surface 103B. Dovetail 105B includes tip 106B having internal surface 106D.

Guard end 102B preferably has a sinusoidal configuration and has a tapered configuration that generally follows the tapered configuration of tapered razor 104, that is, guard end 102B has a back end vertical height (proximate to back end 104F of tapered razor 104) that is greater than a tip end vertical height (proximate to tip 106A of dovetail 105A).

Cover 103 has a tapered configuration that generally follows the tapered configuration of tapered razor 104, that is, cover 103 has a back end vertical height (proximate to back end 104F of tapered razor 104) that is greater than a tip end vertical height (proximate to tip 106B of dovetail 105B).

Tapered razor 104 has a tapered configuration where the vertical height is greater proximate to back end 104F than the vertical height proximate to tip end 104E.

When tapered razor assembly 100 is assembled, internal surface 102D of guard 102 is fixedly secured to surface 104D of tapered razor 104 and internal surface 103C of cover 103 is fixedly secured to surface 104C of tapered razor 104. In a preferred embodiment, guard 102 and cover 103 are melted onto the respective surfaces of tapered razor 104. However, it should be appreciated that alternative securement means may be contemplated, such as fasteners, snap-fit protrusions arranged on cover 103 and guard 102 and respective attachment apertures arranged within tapered razor 104.

When tapered razor assembly 100 is assembled, internal surface 106C of tip 106A of dovetail 105A is arranged to be fixedly secured to internal surface 106D of tip 106B of dovetail 105B—forming dovetail 105 of tapered razor assembly 100. Dovetail 105 is arranged at tip end 101A of tapered razor assembly 100.

The following description should be taken in consideration of FIGS. 20A and 20B. FIG. 20A is a cross-sectional view taken generally along line 20A-20A in FIG. 12 and FIG. 20B is a cross-sectional view taken generally along line 20A-20A in FIG. 12. FIG. 20A specifically illustrates slot 50′ without tapered razor assembly 100 therein and FIG. 20B specifically illustrates slot 50′ with tapered razor assembly 100 therein.

Slot 50′ shares many of the configurations of slot 50 (shown in FIG. 11). Specifically, both slot 50′ and slot 50 have closed ends 51 (shown in FIG. 11) and 51′, respectively. Both slot 50′ and slot 50 have open ends 52 (shown in FIG. 11) and 52′ (shown in FIG. 20). Slot 50′ generally opens into static blade member 11 from back edge 84, specifically opening into chamfer 84a. Chamfer 84a terminates into walls 54 and 55 and slot 50′, where walls 54 and 55 merge into base 53 of slot 50′. It should be noted that chamfer 84a may, or may not, be present in slot 50′.

In a preferred embodiment, angle a1 of slot 50′ is approximately 45°, angle a2 of slot 50′ is approximately 45°, and angle a3 of slot 50′ is approximately 45°. It should be appreciated that the preferred angles of angles a1-a3 are merely exemplary and alternative angles may be acceptable and contemplated.

In a preferred embodiment, radii r1 and r2 are approximately 0.03″. It should be appreciated that the preferred radius of radii r1 and r2 are merely exemplary and alternative radii may be acceptable and contemplated—however, r1 and r2 should be substantially equal.

As shown in FIG. 20B, tapered razor assembly 100 is arranged to be slidably inserted into slot 50′, such that bases 102A, 103A, and 104B all rest on base 53 of slot 50′ and external surfaces 102C (of guard 102) and 103B (of cover 103) contact walls 55 and 54 of slot 50′, respectively. Dovetails 105A and 105B are also arranged to rest on back edge 84 when tapered razor assembly 100 is inserted within slot 50′.

FIG. 21 generally illustrates static blade member 11 having slot 50′ (illustrated in hidden lines). As shown, tapered razor assembly 100 is arranged to be inserted into slot 50′ from open end 52′ until the respective tip ends of tapered razor 104, cover 103, and guard 102 abut closed end 51′ of slot 50′. FIG. 21 also shows tapered razor assembly 100′ (in broken lines) within slot 50′, such that tip 106′ of dovetail 105′ extends past closed end 51′ of slot 50′ and rests on back edge 84—removing snag point SP (shown in FIG. 2), and such that dovetail 105′ rests on back edge 84.

It should be noted that tapered razor 104 may comprise a plurality of grind-types, such as a flat grind, a full hollow grind, a half hollow grind, or other similar grinds known within the art.

It will be appreciated that various aspects of the disclosure above and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
