Description

Hair trimming device with removably mountable components for cutting off bifurcated ends and styling hair

Technical Field

The invention relates to an improved hair trimming device, in particular to a device which can perform preset equal trimming on the tail ends of individual hair shafts far away from hair follicles so as to trim the branched hair ends caused by frequent combing and can keep the original hair shafts which are immediately longer when trimming the hair shafts with preset lengths. The device also has a detachable blade structure for the user to adjust the length of the cut hair and optionally for hair drying purposes.

Background

The trend is changing and the hair of a person is growing and needs to be cut, so people in the united states and around the world often visit hairdressers and barbers. Hair stylists and hairdressers are trained to cut hair with electric and hand-held implements such as scissors and electric clippers, according to the requirements of the guests. Sometimes one wishes to cut a new hair style, but most of the time they are satisfied with their hair style and only need to cut a specified amount of hair from the ends. However, either a trained stylist or an amateur must cut the hair for the person who is to cut the hair, the split ends must be cut to make the hair look good. Brushing hair causes the ends to branch continuously, making the hair appear unhealthy and sometimes stylish.

Current methods of cutting split ends, whether a professionally trained stylist or amateur, are time consuming, must pull the hair by hand or by a comb or both, and then carefully cut individual ends a distance away from the skull follicle, which can result in rough marks, uneven cuts, or other undesirable results in the hair of the person being cut.

For men and women whose hair lengths are to or below the shoulders, split ends are a particularly annoying problem. Because of the different lengths of hair strands from the ears to the shoulders or below, it is particularly time consuming to cut a relatively small but equal amount of the hair ends without accidentally cutting off the immediately adjacent long strands. This procedure is more difficult when the length of the hairstyle is graded, and only a short length of the hair ends need to be trimmed to retain the graded hairstyle. Professional hairstylists can trim the split ends of the long hair of guests for a few hours. Basically, a person with long hair cannot trim the split ends behind his head by himself, but the trimming with the mirror and the scissors is dangerous, and the long hair bundle originally next to the split ends of the short hair bundle can be damaged by cutting off a part of the long hair bundle by a short hand. A variety of hair cutting devices have been developed over the years for use by amateurs and professional hairstylers, which attempt to allow amateurs to cut professional hair styling, or to provide professional hairstylers with another tool to improve their ability in the industry.

While many devices address the problem of cutting and styling, few devices address the split ends of the end of hair and cut only a small preset length of unhealthy ends. Moreover, even if the ends of longer hair do not split, the hair does not grow at the same rate, and the ends of the aged hair shaft are generally cut off to beautify the hairstyle, avoiding the appearance of loose and unattractive ends of the hair shaft. To cut off damaged or unappealing hair shaft ends without damaging or significantly altering the hairstyle, only a small section of the hair shaft ends is cut without affecting the original long and healthy looking hair shaft. The hundreds of hairs on the head can be a very tedious and nearly impossible task.

U.S. patent No. 5,519,939 (Smith) discloses a rotatable hair brush, comb and blade combination that cuts a wide range of hair when in use. However, the user needs to make many adjustments when using the device, and the device cuts long lengths of hair primarily according to the circumference of the rotatable brush. The device may not be configured to cut only a small, relatively equal amount of hair from the ends to cut split ends and unhealthy or unappealing ends. Furthermore, as the brush is rotated by hand between the hairs, the user is constantly exposed to risks including the possibility of having their hair entangled in the brush or the device being pulled sideways between the hairs and accidentally cutting off large bunches of virgin hair. These razor blades generally pull the hair up to cut it, rather than cutting it in a cutting action, which can cause significant discomfort to the person being cut.

Us patent No. 3,115,143 (Queen) discloses a hair trimming guide where the user can cut the hair from the neck line to the temple, with the hair tapering off and down. However, this device requires the user to hold the guide in one hand and the electric shears in the other, which arrangement is such that the user cannot cut his or her hair and requires the hairdresser or other person to use the device for cutting his or her hair with a long period of concentration, and it is essentially impossible for the user to cut his or her hair behind with this invention. Moreover, the method disclosed in the referenced patent is directed only to thinning hair, and not just cutting off split hair. In addition, it is not possible with this device to cut off a relatively equal amount of individual hairs without touching the immediately adjacent long hair strands without a great deal of effort and time.

U.S. patent No. 5,213,116 (Stein) discloses a hair grooming device that uses a rotatable blade mounted on a comb guide. However, this device is designed only to trim a sea and not a bifurcated tip, and since it requires two hands to operate, it is difficult for the user to apply the device behind the head without a third party to help guide the device. Again, achieving a relatively equal amount of wasted time from end trimming requires a high degree of sensitivity.

Us patent No. 5,884,402 (talawira Talavera) discloses a unique device which can achieve the difficult task of cutting only the hair ends, which can be used by trained hair stylists or amateurs. The hair trimming device can also be used by one person under certain limitations. The drive motor of the scissors blade rotates in a single direction, so the device must be operated with the right hand, and hair can only enter from one end. The limited hair guides on the surface of the device, while functional, do not necessarily allow hair to pass straight through the device on rollers, and the blades need to cooperate with a good cutting action to cut the ends effectively.

Accordingly, there remains a need in the hair styling industry for improved hair trimming devices, particularly for cutting off bifurcated ends and trimming a predetermined length of hair from the ends.

Disclosure of Invention

The device is a hair care implement having interchangeable components that provide a user with a settable clipper to cut a relatively equal amount of small strands of hair that branch off, are unsightly, or unhealthy. The device may incorporate various components to vary the length of hair to be cut, or to act as a drying device, or to cut some portion of hair using a cutter if desired. The act of cutting off the split ends only cuts off the ends of the hair and does not cut off the next longer length of hair before the device reaches the ends.

The present invention incorporates several improvements to enhance and improve its operation, including removable or replaceable interchangeable components that allow for varying lengths of hair cut, allow for manual hair trimming, or drying while straightening hair. When sold or supplied in kit form, the user may interchange the improvements provided by the various components to achieve the desired result. In use of the device, as hair passes through the central structure of the engagement locator, the distal ends of the hair shafts will flip into the position of the scissor blades, and the longer hair shafts will remain in the central portion of the locator until they reach the distal end position, creating a novel serpentine motion of the hair within the device, said improvement in combination with the aforementioned method of use enhancing the capabilities of the device.

Through the improved member, the user presses the retainer actuating lever toward the handle to raise the engagement retainer to the operative position to secure the hair shaft to the bevel pressure member. The angle of the bevel pressure member determines the length of the remaining hair bundle before the ends are flipped into the blades of the scissor assembly. The pressure member provides several different angles to cut different lengths of hair. The bevel pressure member slides inside and outside the scissor head using two dovetails on the side of the locator cavity. The bevel angle adjustment member is provided with two mating dovetail grooves, allowing the device to be used with a plurality of different angle members. With this novel combination, the user can determine the precise amount of hair cut from the shaft using the cut length adjustment mechanism as the hair traverses the serpentine path of the device.

The present invention provides a unique hair cutting assembly and drive system that is turned to switch the device switch and motor drive blade orientation so that the clipper can be held in either hand and hair can be moved through a hair serpentine from left to right or from right to left. The removable scissor assembly in the scissor head is provided with an internal drive gear that connects rotatable scissor blades secured to either end of the blade frame by nylon bushings. The drive motor in the scissors body is provided with a gear system including a fixed gear extending outwardly to engage the internal gear of the scissors assembly. Shear plates on either side of the frame allow the blades to rotate in both directions and effectively cut hair. The shear plate has a locating edge and two locating blocks to secure it in the precise position of the blade frame with its cutting edge turned downwardly to engage the cutting edge of the shear blade. The shear plate is mounted to the blade frame by three self-tapping screws through the flexible ring to provide resiliency to the shear plate and to maintain uniform pressure against the blade edge surface.

The hair engagement locator that is turned into the cavity of the scissor head locator is provided with a side structure of the traditional brush head. Each edge has a plurality of spines along an outer edge and a series of ridges on a flat surface to ensure that hair is retained in the plurality of spines of the removable spine member connected to the scissor head. The removable spine member may be supplied in a kit form including a different number and length of spine members and manufactured from different resilient plastic compositions.

The hair is rotated therein and turned upwardly into the hair retainer central structure of the scissor blade, providing a smooth curved surface and a plurality of teeth that hold the hair shaft to pass straight through the hair serpentine. Without the aid of removable pawl members, the hair is guided solely by the pawl members and teeth in the hair positioner, allowing the hair to pass directly over the surface of the scissor head, which also trims the hair.

The scissor head assembly may be an independent attachment or a plurality of scissor head assemblies may be provided in the form of a tool set, each having a plurality of small protruding spines which cooperate with continuous slots which enclose the opposing ends of the scissor body, securing it in place and being detachable with slight axial pressure. The scissor head includes two side projections with a locator cavity therebetween. Each side projection has four holes for connection to a removable spine member, with a locator cavity between the projections, and a top projection with a removable transparent door for trimming the tips within the confines of the inner shell. A locking pin extends outwardly from the scissor body on the scissor assembly adjacent the mating end through an aperture in the scissor head and a mating aperture in the rear end of the transparent door. The locking pin ensures that the door closes when the scissor assembly is connected to the motor, providing a means of securely sealing the device, since the blade operates upon firm depression of the pin. Another safety measure is to provide a grid in the cavity of the retainer so that the hair is only about.375 inches turned up into contact with the blade, and there is not enough room for a finger to be inserted into the blade.

The electric driving motor of the scissors head is arranged in the scissors body, and the pivot mechanism of the hair positioner and the positioner starting rod are also arranged in the scissors body. The diverter switch is located at a convenient location that can be actuated by the thumb while using the other fingers to operate the positioner actuating lever. Two power pins and one ground pin are provided in the handle mating cavity for the handle mating holes when the device is wired using a household power source, or two electrical connections are made as shown in the figures when a battery or a rechargeable sealed electrical handle is used.

Another embodiment of the device is characterized in that the scissor body assembly is provided with two parallel side projections extending from the body assembly opposite the handle. This embodiment features mounting pins behind the side projections opposite the slots, which pins can serve as a mounting for add-on blade assemblies, hair drying assemblies, or when the assemblies are disassembled, if desired, to provide a means to access hair passing through the slots for manually cutting the hair.

It is an object of the present invention to provide a hair trimmer that can cut a more precise length of hair from the ends of a bundle of hair.

It is another object of the present invention to provide a device that can be operated by either hand of the user and that can be turned by a switch to adjust the direction of the electric motor so that hair can be moved through a serpentine path in either direction.

It is another object of the present invention to provide a device that continuously controls hair passing through a serpentine path through the spine of the hair positioner, the spine on the removable spine member, and the teeth on the top of the central structure of the positioner.

It is another object of the present invention to provide a pair of scissors which can be provided with different length adjustment mechanisms to ensure an accurate length of the cutting end of the hair shaft.

An additional object of the present invention is to provide a uniquely designed scissor assembly that utilizes the elastic resistance of its two cutting surfaces to rotate in either direction, cutting hair equally well.

Other objects of the present invention will be shown hereinafter, and the following examples are given for the purpose of disclosing the present invention in detail, and not for limiting the present invention.

Detailed Description

As shown in fig. 1, the hair clipper assembly 10 is shown in an exploded perspective view, with the main components of the clipper assembly 10 including a scissor head assembly 12, a scissor blade assembly 14, a scissor body assembly 16, and a handle 18. The scissor head assembly 12 is provided with a hair removal transparent door 20 which is shown disengaged from a top projection 21 of the inner housing extent 22 carrying the distal end of a hair shaft 23 to be cut through the device, and a locking aperture 24 at its distal end which cooperates with an aperture 26 in the scissor head, aligned with a locking pin 28 of the scissor body 16, so that when the scissor head assembly 12 is engaged with the scissor body 16, the hair removal door 20 cannot be removed, thereby providing a means for preventing a user from contacting the inner housing extent 22 during operation of the device 10.

A plurality of raised ridges 30 are provided along the inner peripheral edge of female end 32 of scissor head assembly 12, with continuous recesses 34 around the inner edge of male mating end 36 of scissor body 16, providing a means for proving engagement of scissor head assembly 12 and scissor body 16, keeping the two coupled together under normal operating conditions. Only a slight axial pressure is required to disengage scissor head 12 from scissor body 16. Upon disassembly, hair door 20 is removably removed from scissor head assembly 12 to clean the extent 22 of the inner housing for storing the cut ends from hair shaft 23.

The flat surface 37 of scissor head assembly 12 is provided with two side projections 38A and 38B that are provided with holes 40 to engage locking blocks 42 of removable ratchet members 44A and 44B. The removable spine members 44A and 44B are supplied in nested form, providing different numbers and lengths of spine members 46, which are manufactured from different resilient plastic compositions. Of course, the ratchet body 46 could be integrally formed with the two side projections 38A and 38B if the removable function is not required, but the presently preferred embodiment employs removable ratchet body members 44A and 44B.

To ensure user safety, the elongated slot 51 of the locator cavity 50 is provided with a grill 47. The grill 47 has a grill opening 53 that provides sufficient space for the end of the hair shaft 23 to pass through for trimming by the cutting blade 72, but insufficient space for a finger to be inserted. This provides a safety measure to reduce the likelihood of the user's fingers being damaged by the scissor blade 72. The grill openings 53 in grill 47 prevent the ends 25 of hair from contacting the scissor elements 72 at an oblique angle by providing individual openings in grill 47 for the ends 25 of hair shafts 23 to align with the scissor elements 72, thereby aligning the ends of hair shafts 23 in contact with the scissor elements 72.

When a user presses on locator actuator lever 109 with a finger to depress scissor body 16, or is spring loaded by the user to depress lever 109, opening and raising hair locator 105, hair engaging locator 105 is rotated by pivot mechanism 106 into locator cavity 50 between the side projections of scissor head assembly 12. However, the presently preferred embodiment is configured so that the user depresses the hair retainer 105 into the retainer cavity 50. Hair retainer 105 includes two cooperating sides 110A and 110B that operatively engage projections 38A and 38B of scissor head assembly 12. The outer edges 112 of the two mating sides 110A and 110B have a plurality of barbs 114 that guide the hair shaft 23 through the hair serpentine 58. In the presently preferred embodiment, when the hair retainer 105 is recessed into the retainer cavity 50, the surface of the hair retainer 105 proximate the slot 51 has a plurality of ridges 55, with spaces between each ridge 55, which align with the grid openings 53 and form a plurality of serpentine bends for hair to pass through the device 10 in use. The engagement of ridges 55 with grid 47 also maintains hair shaft 23 in a generally straight path through the device, thereby avoiding the opportunity for distal end 25 of hair shaft 23 to contact shear blade 72 at an oblique angle.

The opposing surface 107 of hair locator 105 engages the angled hem 56 of face plate 60 at an oblique angle and forces the hair shaft 23 through the hair serpentine 58 thereby tensioning the hair shaft 23. Pressing the hair locator 105 into the locator cavity 50 applies pressure to the hair shaft 23 drawn through the hair serpentine 58 formed by the engagement of the hair locator 105 and the locator cavity 50. The ratchet bodies 46 of the removable ratchet members 44A and 44B rest on the flat surfaces of the ratchet members 44A and 44B and engage the flat surfaces 118 of the engagement detents 105 to assist in forming a designated path between the teeth 124 on the surface of the hair detents 105 and the ratchet bodies 46 for the tensioned hair shaft 23 to pass through to maintain the hair shaft 23 in a straight path through the hair serpentine 58 when passing through the device 10 in use, the straight path reducing the chance that the end of the hair shaft 23 will accidentally tip as it passes through the hair serpentine 58, causing the scissor blade 72 to cut off excess hair.

The tensioned hair shaft 23 will pass over the hair central structure 120 of the hair retainer 105 causing the ends of the hair shaft 23 to be thrown upwardly and tucked through the elongated slots 51, and the pressure on the ends will be briefly released as they exit between the hair retainer 105 and the angled lips 56 causing hair to be cut between the resilient cutting edges 88 and the scissor blade edges 90. The central structure 120 has a smooth curved surface 122, a given radius, and in the presently preferred embodiment a plurality of teeth 124 that help maintain the hair shaft 23 straight through the hair serpentine 58 in a given path and encourage the end of the hair shaft 23 to be cut a given length through the adjacent grill opening 53. The grill openings 53 and the teeth 124 are positioned such that the teeth 124 are inserted straight into the metal portion between the grill openings 53 to further guide the hair shaft 23 through the device 10 via a desired path.

Dovetail 48 engages either side of locator cavity 50 to incorporate a hair length adjustment mechanism 52 to adjust the length of hair cut through elongated slot 51 to the end of hair shaft 23 of shear blade 72. The hair-cutting length adjustment mechanism 52 of this embodiment is characterized by its dovetail grooves 54 in two angled lips 56, which allow the mechanism to slide into the dovetail 48 of the locator cavity 50. The different angles formed on the edge 56 vary the pressure applied to the hair shaft 23 passing through the hair serpentine 58 because the contact surface area of the edge 56 engaging the hair locator 105 is proportional to the pressure experienced by the hair shaft 23, and varying the angle of the edge 56 consequently varies the contact surface area and therefore modulates the pressure applied to the hair shaft 23. The longer the contact surface, the more pressure the hair shaft 23 is subjected to, the shorter the ends will be brought into contact with the shear blade 72, and conversely the smaller the contact surface, the longer the strands of hair will be brought into contact with the shear blade 72, since when the pressure is removed, the ends of the hair shaft 23 will be moved earlier out of contact and spring upwards through the elongated slots 51. The panel 60 holds two oblique edges 56 and seals the ends of the retainer cavity 50. A plurality of such panels 60 may be provided for use with the device 10, each of which may be provided with a different angled hem 56 to provide a different contact surface and different points of pressure and pressure release for the hair shaft 23 passing through the hair serpentine 58, thereby adjusting the amount of hair cut at the end of the hair shaft 23 passing therethrough.

Scissor assembly 14 slides into inner housing range 22 of scissor head assembly 12. In some cases, scissor assembly 14 may be fixedly disposed within inner housing area 22. The scissors frame 70 holds the scissors blade 72 between two bushings with an internal drive gear 76 mounted axially outside the frame 70. Two shear plates 78A and 78B are mounted to frame 70 with mounting screws 80 through flexible loops 82. Shear plate retainer edges 84 and two shear plate retainer blocks 86 secure shear plates 84 in a precise position. The elastic shear plate edge 88 and the shear blade edge 90 are responsible for the shearing action, effectively shearing the tail end of the hair shaft 23. Shear plates 78A and 78B are positioned in opposition, and with the unique configuration of shear blade 72, the cutting action is performed regardless of whether the drive motor is rotating in either direction. The use of shear plates 78A and 78B provides an additional means to adjust the length of hair cut through the elongated slot 51, and varying the thickness of shear plates 78A and 78B moves the cutting blade 72 closer to or away from the end of the hair contacting the cutting blade 72, thereby providing a means to adjust the cut length. Thus, the device may be provided with a plurality of differently configured scissor assemblies 14, each having a scissor plate that moves the scissor blade 72 toward and away from the elongated slot 51 for the end of hair in contact with the scissor blade 72.

The scissor body 16 houses a conventional drive motor and gear system that engages and drives the scissor blades 72 through the internal gear 76. The diverter switch 94 provides a means for changing the direction of rotation of the scissor blade 72 to reverse the direction of the dc current supplied to the drive motor, which is located at the top of the assembly for thumb actuation, although other means for changing the direction of the motor may be found by those skilled in the art and are contemplated. Although it is not necessary to change the motor steering, it facilitates the function of the device in the presently preferred embodiment because the user turns the cutting blade 72 in the correct direction, i.e., the direction in which the device 10 is pulled, and the user can operate the device 10 with either hand, which is necessary because the user pulls the device 10 with the left hand and must reverse the direction with the right hand for use, while the cutting blade 72 acts as a pair of rotary scissors, as with manual scissors, the preferred operation being one in which the cutting direction is preferably relative to the direction in which the device 10 is pulled.

Another embodiment provides another method of adjusting the cut length of hair at the end of hair shaft 23 extending through elongated slot 51 by incorporating scissor head assembly 12 and scissor blade assembly 14 as a removable scissor head of scissor body assembly 16. In this embodiment, a plurality of independent scissor heads may be provided, each set with a different distance between the scissor blade 72 and the elongated slot 51, thereby cutting off a specific amount of hair passing through the end of the hair shaft 23 of the elongated slot 51. A plurality of individual scissor heads of different settings are provided in a nested configuration, and the user can change the length of the hair ends cut from hair shaft 23 by simply rotating the individual scissor heads of different settings and mounting the appropriate individual scissor head to scissor body assembly 16.

As shown, handle mating cavity 96 houses an electrical connection 98 that connects to the electric motor of scissor body assembly 16. The power source is a battery 100 in the handle 18 or a conventional ac power source connected to a transformer. In the preferred embodiment of the device, the battery 100 disposed in the handle 18 may be a disposable battery or a sealed rechargeable battery that can be recharged in a conventional manner at the charging station. Handle 18 provides an attachment end that can be inserted into cavity 96 of scissor body assembly 16 and removed with slight axial pressure.

Although handle 18 and body portion 16 of the illustrated device are shown as being integral with each other, the functional advantages of the device may still be realized because removable scissor head 12 and/or removable scissor blade assembly 14 may still easily change the amount of hair cut from the end of tensioned hair shaft 23 that passes through hair serpentine 58.

Fig. 5 illustrates another embodiment of the device that adds the function of removing and replacing scissor assembly 14 by mounting a scissor assembly 126 with a motor that engages scissor head assembly 12, scissor blade assembly 14, and battery 100, all mounted within a separate scissor assembly 126. An electrical connection on the fork 132 may provide an electrical connection to the switch 94, and the same electrical connection 138 may also be connected to a battery charger of the scissor assemblies 126, or to the battery 100 of the handle 130. This embodiment still provides the advantages of detachable scissor assembly 14 and the ability to adjust the distance of scissor blades 72 to change the length of the ends cut from hair shaft 23, with the additional advantage of detachable scissor assemblies 126 and the ability to change scissors as needed. This embodiment features a single body 128 having a handle 130 at one end, a pair of tines 132 defining a shear slot 134 between the tines 132. In use, scissor assemblies 126 engage the back of tines 132 and the front of the opposite tine will engage hair locator 105. The hair shaft 23 thus follows the same serpentine curve in front of the fork 132 and springs upwardly into the scissor slots 134 for the attached scissor assemblies 126 to scissor off, or in some cases, the scissor assemblies 126 may be moved away to scissor-cut the end of the hair shaft 23 that passes through the scissor slots 134.

Fig. 6 and 7 show another preferred embodiment of the device 11. This embodiment operates on the same principle as the previous embodiment, but also engages the locator cavity 50 with the engagement locator 105 to form a hair serpentine 58 for the hair shaft 23 to pass through. The end of the hair shaft 23 passing therethrough will be briefly sprung and cut off in the manner described above.

The device 11 of this embodiment features a handle 18 having a front face 19 and a rear face 17. The first side projection 38a and the second side projection 38b are connected to the handle 18. A locator cavity 50 is formed between the first and second side projections 38a and 38b so that the two together contact the handle 18. An elongated slot 51 is disposed at the bottom of the locator cavity 50 and passes behind 39 the first and second side projections 38a and 38 b.

The scissor assembly 14 is mounted to the scissor head assembly 12 which is connected to the scissor body assembly 16, all within a scissor assembly 15, forming the scissor assembly 15, mounted to the rear 39 of the first and second side projections 38a and 38b by mounting pins 108 which engage mounting openings 110 in the front of the scissor assembly 15. The mounting pins 108 also provide a means to transmit electricity to the motor of the scissor assembly 15 as an electrical connection to a mounting opening 110 connected to a drive motor disposed within the scissor assembly 15.

This secondary embodiment of apparatus 11 provides a quick action to easily mount and dismount the entire scissor assembly 15 and scissor assembly 14. Thus, a plurality of differently configured scissor assembly assemblies 15 may be provided for the device 11, which may be mounted with the mounting pin 108. Each of the scissor assembly assemblies 15 is configured to cut hair of different designated lengths from the end of the hair shaft 23, and a user can easily adjust the amount of hair cut by simply switching the scissor assembly assemblies 15 of different configurations. The power supply through the mounting pin 108 may be provided in the manner previously described from a battery stored in the handle 18 or from alternating current supplied from an electrical cord connected to the mounting pin 108.

This alternative embodiment of the device 11 may also provide the additional function of using a hair serpentine 58 that causes the ends 25 to spring up and through the elongated slots 51. First, when the scissor assembly 15 is removed, the tip 25 is visible as it rises into the elongated slot 51, so that a very careful tip 25 can be cut off with a cutting knife (not shown). Second, the hair drying assembly 112 may be provided in a removable assembly kit, and the hair drying assembly 112 may be used with a conventional hair drying assembly, including a source of heat and a fan, for brushing hair with the device 11, and drying and straightening the hair shaft 23 by the user. Power can be delivered to the fan motor through the mounting opening 110 and the mounting pin 108 attached thereto in the same manner as the scissor assembly 15. Thus, using the hair serpentine 58 and the specified number of tips 25 raised into the elongated slot 51, different removable assemblies of the kit can be used to cut more or less hair from the tip 25, dry the hair, or use the cutter by hand.

This description details the essential features of the invention in a specific embodiment, and the above description contains similar adaptations or variations or alternatives. In addition, the invention may be applied by those skilled in the art without departing from the spirit of the invention and without exceeding the scope of the claims. Accordingly, all such modifications, variations and alternatives are intended to be included within the scope of the invention as defined in the following claims.
