Embodiments of the present invention relate to vibratory devices in which the whirling motion is converted into pulses for improved carding of curled or messy hair, wherein the combing can be performed with less effort and less damage to the hair. Hair and grooming.

Vibration combs are well known in which a vibratory movement is applied to the combs to enhance the combing or combing effect. For example, U.S. Patent No. 3,517,235 (issued to Flowers et al.) discloses a reverse-drive reciprocating combing unit for providing a combing and massaging action whereby a user traverses the hair with the comb. The tangled hair can be effectively geographically smoothed. The disclosed comb is said to provide improved operability in operability by reciprocating a pair of combing units that effectively tangled hair when performing a combing operation Pull open. Unfortunately, this reciprocating action has been found to be unfavorable for a carding operation because it would have the potential to damage the hair due to the shearing action of the reciprocating combing action.

Other vibrating comb embodiments typically include a fancy comb in which all of the combs move together, but also include a vibratory movement having a component for moving toward and away from the user's scalp to apply to the scalp A slap and massage action. U.S. Patent No. 2,465,250 discloses a vibrating comb comprising a horizontally mounted motor. The vibration generated by the motor is converted into pulses in the carding portion of the device. Such The comb is thus moved in a direction toward and away from the scalp during use. Over time, the slap motion of the scalp may cause discomfort to the user and has only limited effectiveness for the actual combing of the hair, which is primarily for a massage application.

Accordingly, there is a need for a vibrating comb that has an improved combing effect on curled or tangled or knotted hair that operates on a selection plane that enhances carding effectiveness in a manner that minimizes damage to the hair and which The user's scalp is comfortable during operation.

Accordingly, a first aspect of the present invention provides a vibration comb for enhancing hair combing, comprising a head portion including a motor assembly for operating a shock actuator and a slave a plurality of combs of the head portion of the head portion, wherein the actuator is configured to cause the combs to vibrate in a direction substantially parallel to a curve parallel to a plane of the comb mat mobile.

A second aspect of the present invention provides a vibration comb for enhancing hair combing, comprising a motor for operating an actuator to move a plurality of combs operatively coupled to the motor such that One of the distal ends of one of the combs is moved in a curved manner in a plane substantially perpendicular to the direction in which the majority of the comb extends.

A third aspect of the present invention provides a vibrating hair comb for enhancing hair combing, comprising a head portion including a shock for causing a vibrational movement in the plane of the actuator And a comb having a plurality of combs, wherein the comb mat is coupled to the actuator The comb pad is vibrated in a curved direction in a plane substantially parallel to one of the actuator planes.

The following is a more detailed description of any of the first to third aspects of the invention.

The carding curve movement enhances the combing of the hair in a manner that allows the user to have greater comfort. By moving the combs in a plane substantially parallel to the comb pad, the user does not feel the discomfort caused by the high frequency vibrations of the comb tips toward and away from the scalp.

Preferably, the vibrational movement is the same for certain portions of the combs. Although the carding is performed by the vibrating combs, not all of the combs require vibration, and some of the combs may be arranged to function in a conventional manner, except for some combs that are combed by vibration.

Preferably, the comb mat includes a single support member for all of the combs to cause the combs to move together. A single support for all of the combs provides enhanced carding as all of the combs will vibrate consistently.

Preferably, the motor includes a drive shaft that rotates in a direction perpendicular to the general plane of the comb pad. Preferably, the shock actuator includes a biasing weight that rotates in a plane substantially parallel to the comb pad. The offset system that rotates in a plane substantially parallel to the comb pad provides optimized vibration to comb the hair without causing user discomfort.

The physics of how to generate this vibration will be explained as follows: For a mass rotation around an axis that does not coincide with its center of mass, the vibration force or rock power is represented by: Fs = m * r * w ² , where 'm 'The mass of the rotation, 'r' is the distance from the center of mass to the axis of rotation, and 'w' is the angular velocity (rotational speed). In the present invention, the angular velocity 'w' is relatively limited to being represented by a group. The window of the experimental results of the best combing frequency.

Through the knowledge gained from the experimental and numerical models, we have determined that the shaking power used to achieve our desired performance imposes additional restrictions on user comfort and packaging. For the comfort of the user, I have found that the shaking power exceeding a certain amount is not appropriate for the user.

Preferably, the rock power at 40 Hz is from 3 to 5 Newtons, and more preferably from 3.5 to 4.5 Newtons, and the best is from 3.9 to 4.1 Newtons. The best rock power system is approximately 4.03 Newtons.

Preferably, the cylinder has a diameter of from 10 to 20 mm, and more preferably from 13 to 18 mm, and most preferably about 16 mm. The final diameter of the cylindrical weight is preferably confined to the upper end such that the cylinder does not exceed the major diameter of the selected electric motor. This allows the heavy body to be placed on the motor by the motor supplier during assembly and can easily fall into the motor housing.

Therefore, the height of the cylinder is determined after the diameter. Preferably, the cylinder has a height of from 3 to 8 mm, and more preferably from 5 to 6 mm, and most preferably about 5.5 mm.

Preferably, the operating angular velocity is from 32 Hz to 47 Hz. These angular velocities can be measured by consumer and experimental tests to deliver the best combing results.

Preferably, the bias weight system is mounted on one of the shafts of the motor assembly to cause an eccentric bias to be applied thereto to produce the vibratory movement.

Preferably, the offset weight and motor assembly are fixed to the comb pad.

Preferably, the comb includes a power supply in the handle. The power supply is connected to the motor by wires. Preferably, the isolator pivots at its central transverse axis and, more preferably, it includes a through hole through which the electric wire can pass to connect to the motor. The pivoting isolator and wire through holes prevent the wires from being damaged by vibration during use of the comb.

Preferably, the comb pad is resiliently supported by an isolator assembly configured to transform one of the actuators into a circular or elliptical shape and more preferably The elliptical comb pad moves in a vibrating manner. Preferably, the separator is constructed of an elastomeric material such as a styrene butadiene block copolymer or a polyoxyxene elastomer.

Preferably, the isolator assembly is configured to inhibit vibratory movement in one of a direction perpendicular to the axial direction of the handle. Preferably, the isolator is fixed and it is more preferably rigidly secured to the motor housing at its proximal and distal ends relative to the handle of the comb.

Preferably, the isolator is secured to the comb head by a connector at its side transverse to the generally longitudinal axis of the comb. Preferably, the connectors are less flexible than the remainder of the isolator. This reduction in elasticity is achieved by an increase in size or by the use of different materials. More preferably, the connectors extend along the sides of the isolator to between 10 and 70% of the total length of the isolator. More preferably, the connectors have an average depth which is 110 to 300% of the average depth of the isolator at the points of attachment to the comb pad.

In another aspect, the invention provides a method of combing hair comprising combing hair in a comb according to the first to third aspects of the invention.

In this specification, it is to be understood that the term "vibration" as used herein includes oscillations and the term "comb" is understood to include embodiments that may be illustrated by combs.

An embodiment of a vibrating comb provides a solution for achieving better hair combing with minimal effort and less damage to the user's hair during carding. Compared to previous systems, the hair can be combed more pleasingly due to less painful combing operations, thus effectively providing the user with a positive experience. During the carding of the comb, the hair is not "teared" or damaged, but is gently combed with a smaller pull because the vibrating comb barber of the present invention provides a lower frequency and gentler combing. Due to operation. The comb itself can solve the problem of entanglement due to the special vibration type movement, thereby avoiding the user having to take the effort to pull the hair substantially to achieve proper grooming. Hand fatigue can also be substantially reduced during use.

Referring now to Figures 1, 2 and 3, as shown, the present embodiment includes a handle portion A and a comb head portion B. In this specification, it is to be understood that the term "comb" is used to encompass embodiments that may be described as "combs". The handle portion is ergonomically configured and can be easily used when held by a user's hand. One of the longitudinal axes of the handle A is generally along the line C-C of FIG. The comb head portion B includes a plurality of combs 10 which are engaged by one And extending from a bottom wall 12 of the head portion perpendicularly through a user's hair. The illustrated embodiment shows a slightly spherical configuration of the bottom wall 12 as one of the embodiments, but may include other bottom wall configurations as an alternative embodiment, such as flat or tubular. The comb stiffness can vary from hard to soft, although it is preferably harder; when attached to the comb, the comb typically has a cantilever stiffness greater than about 100 Newtons per meter.

As will be detailed herein, the head portion B is used to vibrate and the vibratory movements are isolated from the handle portion A such that the vibrations are not transferred to the handle and the user's hand. For the avoidance of doubt, it should be understood that the term "vibration movement" includes an oscillating or reciprocating movement. Thus, the outer casing of the comb head including one of the top walls 14 is spaced from the handle at the region 16 to accommodate the vibratory movement without causing slamming contact to the handle portion A.

Referring now to Figures 4, 5 and 6, the comb includes a motor 20 for operating the actuator 22, which includes a biasing or counterweight for one of the motor shafts 24 such that when the motor rotates the shaft The weight 22 will cause an eccentric bias relative to one of the shafts to cause a vibrational movement of the motor and the heavy body assembly. This movement will generally have a circular momentum in an actuator plane substantially parallel to a plane defined by lines C-C and D-D of FIG. In this specification, it is to be understood that the term "comb" is used to encompass embodiments that may be described as "combs".

One aspect of this embodiment includes transforming the circular vibratory motion of the motor and the heavy body into a curved form motion (such as an elliptical movement) of the comb mat in a particular plane of motion. An isolating elastic member 40 is attached to the horse Up to 20 and also attached to the comb pad assemblies 10, 12, 14 such that the vibratory motion induced by the motor can be transferred to the combs 10. The motor 20 is received in a cavity 42 in one of the head portions of the comb pad, the cavity being sized to permit rotational movement of the motor 20 and the biasing weight 22 that causes the desired vibratory movement. Since the motor and the heavy body assembly are coupled to the comb head by a strong and rigid connection, vibrations generated by the eccentric weight can be transmitted to the comb head 14. The isolator 40 allows this movement to occur by moving the head largely independent of the handle by closely accommodating the isolator ring ears 50 in the mating tab recess 52. This is achieved by sandwiching the ears between the comb head 14 and the upper motor cover 56 to clamp the ears in the gaps 52. The top wall 14 and the notch 52 are attached to a rigid plastic sheet that ultimately supports the combs 10. The isolator 40 is specifically configured such that the ears are tightly received in the indentations 52, and a crotch panel 60 includes a recess 62 for receiving the cover recess 64 of the fastening cover 56. In addition, the end portions of the elastic tabs 50 and the cymbals 60 are also received in the handle portion notches 70 such that the isolator 40 can effectively isolate the vibrating movement of the head portion from the handle portion A. As shown in Figures 5 and 6, the head portion assembly is thus floatable in the handle portion A because the shock actuator and motor assembly including the cover 56 is spaced from the inner wall 80 of the handle portion. In addition to the portions of the resilient loops received in the handle recesses 70, when the upper handle half 78 is secured to the lower handle half 76, the loops are attached to the indentations 70. Other items shown in Figures 4 and 5 include a battery compartment 90 (however the device can also be connected by wires), a wire passage for the motor 92, and a power supply. Off 94 and a switch pad 96. A decorative cover 98 in the handle 78 covers the motor cover 56.

Although the isolator 40 is an elastomeric material in the illustrated embodiment, alternative forms may include any spring structure that produces similar results, such as a metal spring assembly, a plastic gasket, and other resilient members.

Another aspect of the resilient isolator 40 is that it is configured to transform the circular vibratory movement of the eccentric weight 22 into an elliptical movement in a plane generally parallel to the comb mat. More specifically, as shown, the isolator 40 is unsupported in the direction of the axis CC (Fig. 1), but along a line perpendicular to the axial direction (line D-D of Fig. 1). Supported on the top. The elastomer thus has a first hardness in the axial direction of the handle and a second hardness in the axial direction perpendicular to the handle, the first hardness being less than the second hardness. The effect of this mounting assembly is that the vibrational movement of the motor and the heavy body will be greater along the line D-D in the direction along the line C-C (refer to Figures 1 and 8). If a user's hair (refer to FIG. 7) is mostly aligned with the line D-D (refer to FIGS. 1 and 8), the vibrational movement of the hairs 10 can be compared with the direction perpendicular to the extension of the hair. It is effectively vibrated in a manner that is relatively parallel to this direction. This tends to smooth out the tangled or knotted hair by slightly pulling the hair apart, and even straightening the hair along its extension direction, even during the carding process. The hair is better combed with less effort and less damage to the hair. A related advantage is that the friction (especially static friction) between the combs and the hair can be reduced.

Referring now to FIG. 6, another aspect of the embodiment is that the head portion B is The vibrating movement is performed in a curved plane substantially perpendicular to a user's scalp to avoid vibrating the combs into the scalp, and it has been found that the combing of the combs into the scalp may cause discomfort to the user. feel. In the perspective view of Fig. 6, it can be clearly seen how the eccentric weight 22 exerts an eccentric bias on the motor 20 as the motor shaft rotates, and thus the spacer support member 40 is applied. Eccentric bias. However, since the rotation of the weight 22 is only in the plane of the actuator defined by the line of engagement 82 between the head portion B and the lower half shells 12, 14, the combs are formed. The elliptical movement of the tenth is in a plane substantially parallel to the plane of the actuator.

Another aspect of this embodiment is that the vibratory motion system operates in a frequency range that is substantially lower than most of the prior art vibrating combs. It has been experimentally confirmed that the vibrating combs can be highly efficient combing in a frequency range of 20-100 Hz and more preferably between 30-65 Hz, and are used by the user to pull the comb through From the point of view of the strength required for the hair, the frequency at which the hair is most effectively combed is 42 Hz or 62 Hz. Accordingly, an improved method for combing hair comprises combing the hair with a comb having a vibrating comb that operates in a frequency range of 20 to 100 Hz and is disposed in one of a plane Operating in the direction of the curve, the plane being positioned substantially parallel to a user's scalp or longer hair (Fig. 7), i.e., the extension of the user's hair as the hair extends from a user's scalp flat. The comb includes the combs operating in an elliptical pattern having a first movement in a direction perpendicular to a direction in which a user's hair hangs or extends A longer axis and a second shorter axis parallel to the movement of the user's hair in a direction in which it hangs or extends.

Referring now to Figures 7-9, a method of operating the comb embodiment to enhance hair combing comprises activating the comb such that the combs vibrate in a desired elliptical plane parallel to the comb pad plane 82 (Figure 6). 120. The comb is then aligned 122 to a position relative to the user's hair such that the direction of extension of the hair is substantially aligned with the axial direction DD of the comb head, that is, the elliptical main axis is perpendicular to The direction of the hair. Carding the hair along the direction of extension of the hair will thus provide a carding effect that allows the user to comb more efficiently with less effort to open the knot and minimize the fatigue of the user's hand. hair.

For the hair that is not normally hanging, such as the one shown in Figure 7, that is, the very curly hair that extends extremely outward from the user's scalp, the same principle can be applied, except that the user combs the hair line along the hair. One of the lengths is pulled or fiddled to cause the hair to extend from the scalp outwardly instead of hanging down from the scalp. The invention is particularly suitable for use on the hair as well as longer hair (i.e., over the length of the chin) as well as dry or damaged hair.

Embodiments of the present invention have been described above with reference to combing human hair, but the comb can also be used to comb other items, such as the hair of an animal or pet, or even a tangled strand of other materials other than hair.

The illustrative embodiments have been described above with reference to the preferred embodiments. Obviously, other modifications and changes can be made after reading and understanding the above detailed description.
