Vibration comb

The present invention relates to a vibrating comb having improved carding performance.

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 the user can tangled when the comb is traversed across the hair. The hair is effectively geographically smooth. 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.

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. The combs thus move 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 It is comfortable for the user during operation.

Accordingly, in a first aspect of the present invention, there is provided a vibration comb for enhancing hair combing, comprising a head having a base and a comb carrying pad, the pad comprising a motor and a A shock moving actuator is generated in the pad, the pad being pivotally attached to the base such that the pad pivots about a pivot axis that is generally transverse to the general longitudinal direction of the comb axis.

The rocking motion performed by the mat in the comb according to the present invention provides sufficient forward and backward movement in the combs, which can be combed during use without being oriented and away from the user's scalp. Apparently moving. Therefore, the comb is effective and comfortable during use.

The generally longitudinal axis of the comb is perpendicular to the combing direction during use and will generally follow the axis of the long axis of the comb.

The so-called transverse system means that the pivot axis is perpendicular to the generally longitudinal axis of the comb and lies in the same plane.

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 is perpendicular to the comb The pad rotates in the general plane direction. 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 the rock power is represented by the following formula: 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 a window predetermined by a set of experimental results representing the optimum carding 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.

Additionally, the isolator must have a minimum stiffness such that the head is not too loose due to its own weight when the comb is held upright, and the comb head does not move too much to create a scary appearance or Problems with interference with the handle housing.

Furthermore, the eccentric weight should not be placed too far from the isolator, otherwise the comb would increase to an excessively high device.

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 distance from the motor drive shaft (rotation axis) to the center of the cylinder is from 5 to 9 mm, more preferably from 6 to 8 mm, and especially about 7 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 base is attached to the carding carrier by an isolator. Preferably, the isolator is configured to transform one of the actuators into a circular or elliptical comb pad for vibrating movement, and more preferably an elliptical movement. Preferably, the separator is constructed of an elastomeric material such as a styrene butadiene block copolymer or a polyoxyxene elastomer.

Preferably, the isolator comprises a plate. Preferably, the panel includes a central portion secured to the base and a flexible end positioned at an opposite side of the central portion along a generally longitudinal axis of the comb, the ends being secured to the pad. Preferably, the central portion comprises from 20 to 50%, more preferably from 25 to 35%, of the overall width of the separator. This provides for the shaking of the hair from the vibration of the motor to be fully shaken to the hair without causing scalp injury.

Preferably, the pivot axis is centered in the central portion of the isolator.

Preferably, the comb includes a power supply in the handle. The power supply is connected to the motor by wires. Preferably, wires are routed from the handle to the base and from the sides into the mat and at opposite sides of the pivot axis to prevent the wires from vibrating during use of the comb Damaged.

Preferably, the comb comprises a handle extending from the head portion in the axial direction of a handle. More preferably, the tie is in a plane substantially parallel to the comb pad.

Preferably, the comb pad vibration movement is an elliptical movement having a longer elliptical axis in the axial direction of the handle.

Preferably, the isolator 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.

More preferably, the isolator is clamped to the location above and below the isolator at the connectors.

Preferably, the combs extend from the comb pad in a direction generally perpendicular to the comb pad to cause the comb movement to move corresponding to the comb pad.

Preferably, the vibrational movement is in the frequency range of 20-100 Hz, and more preferably from 30 to 65 Hz. In a comb according to the invention, this frequency range provides optimum grooming without causing user discomfort.

In a second aspect, the present invention provides a method of combing hair, which A hair comb comprising a first aspect in accordance with the present invention is included to comb the hair.

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 that extend perpendicularly from a bottom wall 12 of the head portion in a manner that engages and extends 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. Shaped 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. As the name implies, 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 an actuator that includes a biasing or counterweight 22 for one of the motor shafts 24 such that when the motor rotates the shaft The biasing 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 elastic member isolator 40 is attached to the motor 20 and is also attached to the comb pad assembly 10, 12, 14 such that vibratory motion induced by the motor can be transferred to the combs 10. The motor 20 is housed in a cavity 42 of the head portion of the comb pad, the size of the cavity The rotational movement of the biasing weight 22 that is designed to accommodate the motor 20 and cause 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 B. The isolator 40 allows this movement to be present by moving the head largely independent of the handle by closely accommodating the isolator loop elastic tabs 50 in the mating tab recess 52. This is achieved by sandwiching the ears between the comb head B 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 specially configured such that the ears are tightly received in the indentations 52, and a connector 60 includes a recess 62 for receiving the cover recess 64 of the fastening cover 56. In addition, the end portions of the loop elastic tabs 50 and the connector 60 are also received in the handle portion notches 70, so 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 (although the apparatus can also be wired), a wire passage for the motor 92, a power switch 94, and a switch pad 96. A decorative cover 98 in the handle 78 covers the motor cover 56.

Although in the illustrated embodiment, the isolator 40 is an elastic material, Alternative forms may also 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 eccentrically biased 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 is oriented along a line perpendicular to the axial direction (line DD of Fig. 1). support. 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 straight line DD (refer to FIGS. 1 and 8), the vibrating movement of the combs 10 can be parallel to the direction perpendicular to the extension of the hair. There is a greater degree of vibration in this direction to effectively vibrate. 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 Figure 6, another aspect of the present embodiment is that the vibratory movement of the head portion B is performed in a curved plane substantially perpendicular to a user's scalp to avoid vibrating the combs to In the scalp, it has been found that the shaking of the comb into the scalp causes a feeling of discomfort to the user. In the picture In the perspective view of Figure 6, it can be clearly seen how the eccentrically biased weight 22 exerts an eccentric bias on the motor 20 as the motor shaft rotates, and thus the eccentricity is applied to the isolator 40. Pressure. However, since the rotation of the offset 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 shell (the bottom wall 12, the top wall 14). Thus, the elliptical movement of the combs 10 formed 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 20-200 Hz and more preferably between 30-65 Hz, and are used by the user to pull the comb through the hair. From the point of view of the strength required, the frequency at which the hair can be most effectively combed is 42 Hz or 62 Hz. Thus, 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 set to a curve in a plane Operating in a direction that is positioned substantially parallel to a user's scalp or longer hair (Fig. 7), i.e., the extended plane of the user's hair as the hair extends from a user's scalp . The comb comprising the combs operating in an elliptical pattern having a first longer axis of movement and a parallel to the direction in a direction perpendicular to a direction in which the user hangs or extends The second shorter axis of movement of the hair in the direction in which it hangs or extends.

Referring now to Figures 7 through 9, an embodiment of the comb is used to enhance hair. The carding method includes rotating the comb such that the combs vibrate 120 in a desired elliptical plane parallel to the comb pad plane 82 (Fig. 6). 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.

Figure 10 shows an isolator (40) attached to the comb bearing pad (in the top wall 14) when it is secured inside the comb head such that movement of the isolator (40) causes The carding carrier is moved (in the top wall 14). The motor (not shown) in the pad causes vibration of the isolator, since the isolator is fixed along the connector (60), which causes the ends (B) to move effectively (arrow B") Shake well (arrow C) to smooth out the hair without damaging the scalp. Straightening the hair is achieved by movement in the D direction, while scalp discomfort is caused by movement in the E direction.

Figure 11 shows a preferred isolator of the present invention. The isolator has a central portion A and a flexible end portion B. These end parts are tied at the point Attached to the pad (not shown) at (123) and the central portion is attached to the base at point (124). The central portion is thus fixed without shaking, and the flexible ends can be shaken when the motor is vibrating.

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.
