Cutting comb

Abstract

A split end removal comb. This comb includes an outer shell which houses an inner shell of similar shape but smaller dimensions, and a handle, which houses an electromechanical assembly. The inner comb can slide to a lock position inside the upper part of the outer comb, whereby the hair can be stretched away from the scalp and bent into divided strands. In this position, the blades mounted on the teeth of the inner comb, which can be powered by a motor, can be activated through a shaft running through the perpendicular axis of the device thereby trimming the tips of the hair, as it is being combed by the user. During operation, the hair goes through channels created by the multi-planar arrays of a plurality of teeth, ridges, and blades arranged along various angles and distances. This results in a safe and easy trimming of split ends.

(10) FIG. 9 a simplified schematic cross-sectional view of a part of the cutting comb according to the preferred embodiment.

(11) In the following, a cutting comb 100 for trimming the hair tips of a person and thereby cutting potential split ends of the hair according to a preferred embodiment of the present invention will be described in detail based on FIGS. 1 to 8. In FIGS. 1, 4, 5, 6 and 7 a coordinate system 201 has also been drawn in order to enhance the understanding of the structure of the cutting comb 100.

(12) FIG. 1 shows a perspective view of the assembled cutting comb 100.

(13) The cutting comb 100 comprises a first comb body 1 and a second comb body 2, which are configured to be movable relative to each other in a direction parallel to a longitudinal axis 200 of the cutting comb 100.

(14) More specifically, the second comb body 2 is arranged in a movable manner inside the first comb body 1. To this end, the first comb body 1 is formed as a hollow body and comprises an inner space 103 (FIG. 8), in which the second comb body 2 is positioned. Thus, the first comb body 1 and the second comb body 2 can be considered as an outer and an inner comb body, respectively.

(15) As can be seen from FIG. 8, the second comb body 2 is in particular slidably arranged in the first comb body 1 in the direction of the longitudinal axis 200 of the cutting comb 100. It is noted that the longitudinal axis 200 of the cutting comb 100 is parallel to the Y-axis of the coordinate system 201.

(16) For moving the second comb body 2 relative to the first comb body 1, a push handle 23 is provided on the second comb body 2. The user of the cutting comb 100 pushes the push handle 23 in the direction of the Y-axis of the coordinate system 201, i.e. upwards in this case, when holding the cutting comb 100 by a handle 102, thereby causing the second comb body to be moved with respect to the first comb body 1. The exact function of the cutting comb 1 will be explained later in more detail with regard to FIGS. 7 and 8.

(17) Furthermore, the first comb body 1 comprises a plurality of first teeth 10 and the second comb body 2 comprises a plurality of second teeth 20. In particular, the number of first teeth 10 equals the number of second teeth 20.

(18) In the present embodiment, seven first teeth 10 and seven second teeth 20 are provided. Thus, many hairs can be trimmed at the same time, while the cutting comb 100 is still handy for the user. However, the number of the first teeth 10 and the second teeth 20 can vary and also be different from each other.

(19) Due to the hollow shape of the first comb body 1, each of the first teeth 10 is hollow in order to accommodate/enclose a corresponding second tooth 20, as can be seen from FIG. 1.

(20) In addition, the first teeth 10 and the second teeth are arranged at an angle to the longitudinal axis 200 of the cutting comb 100. The first teeth 10 extend from a first base body 17 of the cutting comb 100 and the second teeth 20 from a second base body 27 of the cutting comb 100. Both the first base body 17 and the second base body 27 extend in the direction of the longitudinal axis 200 of the cutting comb 100. It is noted that the first base body 17 and the first teeth 10 correspond to the first comb body 1, while the second base body 27 and the second teeth 20 correspond to the second comb body 2.

(21) More specifically, the first teeth 10 and the second teeth 20 each extend vertically to the longitudinal axis 200 of the cutting comb 100. In other words, a longitudinal axis 202 of the first teeth 10 and a longitudinal axis 203 of the second teeth 20 (shown in FIGS. 1 and 4, respectively) are vertical to the longitudinal axis 200 of the cutting comb 100. The longitudinal axis 202 of the first teeth 10 and the longitudinal axis 203 of the second teeth are parallel to the X-axis of the coordinate system 201. Thus, it is apparent that the first teeth 10 are arranged parallel to each other. The second teeth 20 are also arranged parallel to each other.

(22) The longitudinal axis 202 of the first teeth 10 and the longitudinal axis of the second teeth 20 are parallel to each other, so that also the first teeth 10 and the second teeth 20 are arranged parallel to each other.

(23) Furthermore, it can be derived from FIGS. 2 and 3 that the first comb body 1 is formed by two parts that are joined together. FIG. 2 shows a first part 13 of the first comb body 10 and FIG. 3 a second part 14 of the first comb body 10.

(24) More particularly, the first part 13 and the second part 14 are identical to each other and symmetrical with respect to a plane comprising the longitudinal axis 200 of the cutting comb 100 and the longitudinal axis 202 of the first teeth 10 (a plane parallel to the XY-plane).

(25) Due to this construction of the first comb body 1, each of the first teeth 10 is formed by a first part 10a and a second part 10b, as depicted in FIGS. 2 and 3, respectively.

(26) The first teeth 10 are arranged such that a distance between two neighbouring first teeth 10 in the direction of the longitudinal axis 200 of the cutting comb 100 is the same for all the first teeth 10. The same applies to the second teeth 20.

(27) In order to facilitate the trimming of the hair tips, the cutting comb 100 comprises a plurality of first hair-dividing elements 11, which are provided in an immovably fixed manner on first teeth 10 of the first comb body 1. The hair-dividing elements 11 are preferably integrated with the corresponding first teeth 10. All first hair-dividing elements 11 are identical to each other in the present embodiment. However, differently shaped and/or sized first hair-dividing elements 11 can be provided.

(28) Referring to FIGS. 2 and 3, it can be seen that in particular all first teeth 10 except one (i.e. six first teeth 10 in this embodiment) each comprise a plurality of first hair-dividing elements 11. The first tooth 10 of the first comb body 1 that does not have any first hair-dividing elements 11 is the one closest to the handle 102 of the cutting comb 100.

(29) More specifically, each of the first part 10a and the second part 10b of each of the first teeth 10 of the first comb body 1 comprises a plurality of first hair-dividing elements 11 on its corresponding inner side. This means that the first hair-dividing elements 11 are directed to/face the second teeth 20 of the second comb body 2.

(30) In other words, each of the first teeth 10 of the first comb body 1 comprises first hair-dividing elements 11 which are arranged on both of its inner sides with respect to a plane comprising the longitudinal axis 200 of the cutting comb 100 and the longitudinal axis 202 of the first teeth 10 (a plane parallel to the XY-plane).

(31) As depicted in FIG. 3, the first hair-dividing elements 11 of the first part 10b are equally distanced from each other in the direction of the longitudinal axis of the first teeth 10.

(32) Between neighbouring first hair-dividing elements 11 first channels 12 are formed. Due to the equal distance between all neighbouring first hair-dividing elements 11 as well as their identical construction, the first channels 12 are also identical to each other.

(33) Advantageously, the first hair-dividing elements 11 are formed as first projections. The first projections are more specifically formed as ribs or ridges. Each of the first projections extends vertically from the corresponding first tooth 10.

(34) The first hair-dividing elements 11 preferably extend over a whole thickness of the corresponding second part 10b of the first tooth 10. The thickness is measured in a direction parallel to the longitudinal axis 200 of the cutting comb 100. Furthermore, the first hair-dividing elements 12 extend over a whole length of the corresponding second part 10b of the corresponding first tooth 10.

(35) Moreover, the first hair-dividing elements 11 each comprise at least one curved portion. This construction contributes to a better guiding of the hair.

(36) In the present embodiment, two curved portions 15 are preferably provided at a first end and at a second end of the corresponding hair-dividing element 11 (FIG. 3). The middle part connecting the first end and the second end is preferably straight.

(37) Advantageously, the first hair-dividing elements 11 of the first part 10a are arranged and formed in the same manner as the first hair-dividing elements 11 on the second part 10b.

(38) Referring now to FIG. 4, a perspective view of the second comb body 2 is shown.

(39) Similar to the first comb body 1, the second comb 2 comprises a plurality of second hair-dividing elements 21, which are provided in an immovably fixed manner on second teeth 20 of the second comb body 2. The second hair-dividing elements 21 are preferably integrated with the corresponding second teeth 20. All second hair-dividing elements 21 are identical to each other in the present embodiment. However, differently shaped and/or sized second hair-dividing elements 21 can be provided.

(40) In particular, all second teeth 20 except one (i.e. six second teeth 20 in this embodiment) each comprise a plurality of second hair-dividing elements 21. The second tooth 20 of the second comb body 2 without any second hair-dividing elements is the one located the farthest away from the handle 102 of the cutting comb 100.

(41) More specifically, second hair-dividing elements 21 are provided on both sides of each of the second teeth 20. The second hair-dividing elements 21 are directed to/face the first parts 10a and second parts 10b of the first teeth 10 of the first comb body 1 and more specifically the first hair-dividing elements 11. The second hair-dividing elements 21 on the sides of each of the second teeth 20 are preferably arranged symmetrically with respect to a plane comprising the longitudinal axis 200 of the cutting comb 100 and the longitudinal axis 203 of the second teeth 20 (a plane parallel to the XY-plane).

(42) As depicted in FIGS. 4 and 6, the second hair-dividing elements 21 are advantageously equally distanced from each other in the direction of the longitudinal axis of the second teeth 20.

(43) Between neighbouring second hair-dividing teeth 21, second channels 22 are formed. Due to the equal distance between all neighbouring second hair-dividing teeth 21, the second channels 22 are also identical to each other.

(44) Similar to the first hair-dividing elements 11, the second hair-dividing elements 21 are also formed as projections (second projections). The second projections are more specifically formed as ribs or ridges. Each of the second projections extends vertically from the corresponding second tooth 20.

(45) In addition, the second hair-dividing elements 21 extend over a whole length of the corresponding second tooth 20.

(46) Moreover, the second hair-dividing elements 21 each comprise at least one curved portion 16 (FIG. 6). This construction contributes to a better guiding of the hair.

(47) As can be understood from FIGS. 7 and 8, the first hair-dividing elements 11 and the second hair-dividing elements 21 are arranged with an offset to each other in a direction in which the first teeth 10 and the second teeth 20 extend, i.e. in the direction of the longitudinal axis 202 of the first teeth 10 and of the longitudinal axis 203 of the second teeth 20.

(48) Furthermore, the first hair-dividing elements 11 and the second hair-dividing elements 21 are arranged such that they overlap with each other in a direction in which the first hair-dividing elements 11 and the second hair-dividing elements 21 extend (parallel to the Z-axis of the coordinate system 201).

(49) Thus, the first channels 12 and the second channels 22 overlap with each other, so that sub-channels are formed between neighbouring first hair-dividing elements 11 and second hair-dividing elements 12.

(50) To carry out the trimming of the hairs, the cutting comb 100 comprises a plurality of cutting means 3. The cutting means 3 are operated by an electric motor 4, as shown in FIG. 8. The electric motor 4 is positioned in the inner space 103 of the first comb body 1, and more specifically on a receiving portion of the second comb body 2. With regard to the position of the electric motor 4 in the cutting comb 100 as a whole, the electric motor 4 is arranged in the handle 102 of the cutting comb 100.

(51) More specifically, a shaft 6 is provided between the electric motor 4 and the cutting means 3, so that the cutting means 3 are operable by the shaft 6 which are in turn driveable by the electric motor 4.

(52) Each of the cutting means 3 is provided on a second tooth 20 of the second comb body 2.

(53) More specifically, all second teeth 20 except for one second tooth 20 each comprise one cutting means 3. In other words, the cutting comb 100 has one less cutting means 3 than second teeth 20.

(54) In the present embodiment, the tooth out of the second teeth 20, on which no cutting means is provided, is the one being closest to the handle 102 in a direction parallel to the longitudinal axis 200 of the cutting comb 100. This second tooth 20 comprises only a plurality of second hair-dividing elements 21.

(55) On the other hand, the tooth out of the second teeth 20 that is in a position being farthest away from the handle 102 of the cutting comb 100 in a direction parallel to the longitudinal axis 200 of the cutting comb 100 is provided with cutting means 3 but no second hair-dividing elements.

(56) Each cutting means 3 of a second tooth 20 is provided on a side of the second tooth 20 facing a side of a neighbouring second tooth 20. As can be seen from FIGS. 4 and 5, each cutting means 3 extends over the whole length of the corresponding second tooth 20.

(57) Moreover, each cutting means 3 is arranged on the same corresponding side of the corresponding second tooth 20.

(58) Furthermore, each cutting means 3 comprises a plurality of cutting blades 30 or knifes. More particularly, the cutting blades 30 or knifes are arranged next to each other to form a row of cutting blades 30 or knifes. It is apparent from FIGS. 5 and 6, that each cutting means 3 comprises two rows of cutting blades 30 or knifes that are symmetrical with respect to a plane comprising the longitudinal axis 200 of the cutting comb 100 and the longitudinal axis 203 of the second teeth 10 (a plane parallel to the XY-plane). Due to this, the cutting comb 1 can be used from both left-handed and right-handed users without any further adjustment.

(59) With reference to FIG. 4, it becomes apparent that an angle 31 between the cutting blades 30 and a plane containing the longitudinal axis 200 of the cutting comb 100 and the longitudinal axis 203 of the second teeth 20 is in the range between zero degrees (exclusively) and ninety degrees (exclusively).

(60) In addition, the cutting means 3 can be configured such that the angle 31 is adjustable within the aforementioned angle range.

(61) According to another advantageous aspect of the present invention, the first teeth 10 and the second teeth 20 are configured to be heatable. To this end, the first teeth 10 and the second teeth 20 can each be provided with a heating element.

(62) The heat being produced by the heating elements is transferred to the hair, thereby shaping and softening the hair. This makes cutting of the hair tips easier.

(63) To further enhance this effect, the cutting 3 means are configured to be heatable in addition to the second teeth 20.

(64) To this end, a heating element can be provided for each cutting means 3 such that the cutting means 3 can be directly heated. By doing so, heat generated by the heating elements can be directly transferred to the hair tips via the cutting means 3.

(65) As a further measurement to enhance the cutting efficiency of the hair tips, the first teeth 10 and the second teeth 20 are made out of a material, preferably a metal, that in combination with the hair does not cause static electricity in the hair. Thus, it can be avoided that the different hairs fly away in different directions, what in turn results in a faster cutting of the hair tips.

(66) Referring back to FIGS. 4 and 6, a top surface 25 of each second tooth 20 facing a cutting means 3 is formed flat.

(67) However, the second teeth 20 facing a cutting means 3 may each be provided with a hair-bending element 26 for bending the hair that is placeable between two neighbouring first teeth 10. The hair-bending elements 26 are shown in FIG. 6 by a broken line. The hair-bending elements 26 are preferably formed as projections projecting from the top surfaces 25 of the second teeth 20.

(68) The hair-bending elements 26 preferably extend over 50%, more preferably over 70%, more preferably over 90%, even more preferably over 100%, of the second tooth, in the direction of the longitudinal axis of the second tooth.

(69) The projections preferably have a cross-section in the form of a triangle. The cross-section is defined in a plane vertical to the longitudinal axis 203 of the second teeth 20.

(70) Each of the projections preferably has a height 204 equal to of a distance 205 between a lowest point of the cutting means 3 that the projection faces and the top surface 25 of the respective second tooth 20 from which the respective projection projects.

(71) In order to improve the directionality and positioning of the hair with respect to the cutting means 3, the cutting comb 100 comprises means 5 being configured to create a pressure in the part of the inner space 103 of the first comb body 1, especially close to where the second teeth 20 are arranged, that is lower than the atmospheric pressure. Due to this, hair is sucked towards the cutting means 3. By doing so, the cutting of the hair is made easier and the efficiency of the cutting comb 100 is improved further.

(72) More specifically, the means 5 for creating the lower pressure than the atmospheric pressure comprises a fan that is preferably arranged on the axis of the electric motor 4. The rotation of the fan is such that it creates conditions of pressure in the inner space 103 of the first comb body 1 being lower than the atmospheric pressure, so that the hairs are sucked towards the cutting means 3.

(73) To this end, the second teeth 20 comprising a cutting means 3 are formed to be hollow. As can be seen from FIG. 6, each of the second teeth 20 comprising a cutting means 3 comprises two openings 24, through which an inner space of each second tooth 20 communicates with the environment (atmosphere). The number of the openings 24 can however vary. The two openings 24 of a respective second tooth 20 are arranged each on one side of the cutting means 3 of the respective second tooth 20.

(74) Further, with reference to FIG. 8, the shaft 6 is designed to be hollow and to comprise a plurality of openings 60, through which the inner space of the shaft 6 communicates with the inner spaces of the hollow second teeth 20. The inner space of the shaft 6 also communicates with the inner space 103 of the first comb body 1.

(75) Thus, the inner spaces of the hollow second teeth 20 communicate with the means 5 for creating a sub-atmospheric pressure in the inner space 103 of the first comb body 1, so that air of the inner spaces of the hollow second teeth 20 can be drawn/sucked into the inner space 103 of the first comb body 1.

(76) The air being drawn through into the inner space 103 of the first comb body 1 by the means 5 for creating a sub-atmospheric pressure in the inner space 103 can exit to the environment through an opening 18 of the first comb body 1 (FIG. 8).

(77) The opening 18 is preferably formed close to the electric motor 4, so that the streaming air can effect a cooling of the electric motor 4.

(78) In the following, the use of the cutting comb 100 will be explained based on FIGS. 7 and 8.

(79) FIG. 7 shows the cutting comb 100 in a first operational state. More concretely, FIG. 7 is a cross-sectional view of the cutting comb 100 in order to enable a better overview of the relative position of its elements to each other in the first operational state. FIG. 8 shows the cutting comb 100 in a second operational state. For a better overview, the first part 13 of the first comb body 1 has been removed in FIG. 8.

(80) In order to use the cutting comb 100, a user holding it by its handle 103 will enter the cutting comb 100 into the hair of person (or its hair). At this stage, the cutting comb 100 must be in the first operational state. In this state, the first teeth 10 and the second teeth 20 are aligned with each other. This means that each first tooth 10 is matched to a second tooth 20. For example, the closest first tooth 10 to the handle 102 is matched to the closest second tooth 20 to the handle 102, and the farthest first tooth 10 from the handle 102 is matched to the farthest second tooth 20 from the handle 102.

(81) In this position, hair will have entered the spaces between neighbouring first teeth 10 and between neighbouring second teeth 20.

(82) After that, the user will push the push handle 23 upwards in the direction of the longitudinal axis 200 of the cutting comb 100 in order to effect a movement of the second comb body 2 relative to the first comb body 1 and thus bring the cutting comb 100 into the second operational state (FIGS. 8 and 9).

(83) In this state, each second tooth 20 will have moved by one first tooth 10. In other words, not all first teeth 10 are matched to a second tooth 20 in this state. More specifically, the first tooth 10 that is closest to the handle 102 is not aligned with a second tooth 20. In this state, the first tooth 10 closest to the handle 102 has an offset from the second tooth 20 closest to the handle 102. This offset equals to the distance between neighbouring first teeth 10 or the distance between neighbouring second teeth 20.

(84) Due to the movement of the second comb body 2 with respect to the first comb body 1, hair 500 that has entered a space between two neighbouring first teeth 10 and two neighbouring second teeth 10, when the cutting comb 100 is in the first operational state, is now lifted by the corresponding second tooth 20 up to the next first tooth 10 in the second operational state. By this, hair 500 gets bent, as can be seen in FIG. 9. It is noted that, for the sake of a better understanding of the cutting operation of the cutting comb 100, a simplified cross-sectional view of only a part of the cutting comb 100 is shown in FIG. 9, in which some elements/features of the cutting comb 100 have been omitted.

(85) At the same time with bending the hair 500 due to the movement of the second comb body 2 relative to the first comb body 1, hair 500 is divided into hair strands due to the second hair-dividing means 21 and the first hair-dividing means 11.

(86) Thus, when the user moves the cutting comb 100 through the hair 500 by combing the hair 500, the hair strands formed by the second hair-dividing means 21 and the first hair-dividing means 11 are moved through the spaces between neighbouring first teeth 10 in a way that their tips 501 are trimmed by the cutting means 3, when the latter are activated. Consequently, any split ends of the hair 500, which occur at the hair tips 501, will be cut off.

(87) For activating the cutting means 3, the electric motor 4 is first activated, e.g. by pressing a button or operating a switch.

(88) The cutting comb 100 as described above has a simple structure and provides for an efficient trimming of the hair of a person.

(89) The depicted and described features and further properties of the invention's embodiments can arbitrarily be isolated and recombined without leaving the gist of the present invention.

(90) In addition to the foregoing description of the present invention, for an additional disclosure explicit reference is taken to graphic representation of FIGS. 1 to 8.
