With reference to FIGURES 7 to 9, a method of operating the present brush embodiment for enhanced detangling of hair comprises turning on the brush so that the bristles vibrate 120 in the desired elliptical plane parallel to the bristle pad plane 82 (Figure 6). The brush is then aligned 122 in a position relative to the user's hair so that the extending direction of the hair is generally aligned with axial direction D-D of the brush head, i.e., where the ellipse major axis is perpendicular to the hair direction. Brushing of the hair along the extending direction of the hair will thus provide a detangling effect that is more efficient in the hair detangling with less user effort to pull out the tangles and with minimum fatigue to the user's hand. The presently disclosed embodiments are directed to vibratory devices wherein gyratory movements are translated into pulses, typically for massage or cleaning, but in this case, for enhanced detangling of curled or unbrushed hair wherein brushing and detangling can occur with less effort and with less damage to the hair.

Another aspect of the elastic isolator 40 is that it is configured to translate the circular vibratory movement of the eccentric weight 22 into an elliptical movement in a plane generally parallel to the bristle pad. More particularly, it can be seen that the isolator 40 is not supported along the direction of the axis CC (Figure 1), but is supported along a line perpendicular to the axial direction and a second stiffness perpendicular to the handle axial direction, the first stiffness being less than the second stiffness. The effect of such mounting assembly is that the vibratory movement of the motor and weight will be greater in a direction along the lines C-C than along the line D-D. (See Figures 1 and 8) If a user's hair (see Figure 7) is mostly aligned with line D-D (see Figures 1 and 8), then the vibratory movement of the bristles 10 will be to effectively vibrate in a manner having a greater extent perpendicular to the hair's extending direction than along, i.e. parallel, to said direction. This tends to untangle twisted or knotted hair by the bristles separating the hairs by slightly pulling them apart, and even more slightly pushing and pulling the hair in its extending direction for better detangling the hair with less effort and less damage to the hair in the detangling process. A related benefit is that friction between the bristles and the hair, in particular the static friction, is reduced.

ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNORS:TAGGART, JEFFREY SILVER;KALMAN, JEFFREY M.;NOTTINGHAM, JOHN RICHARD;AND OTHERS;REEL/FRAME:021263/0929;SIGNING DATES FROM 20080320 TO 20080505 An aspect of the subject embodiment includes the translating of the motor and weight circulatory vibratory motion into a curvilinear pattern, such as an elliptical movement, of the bristle pad in a particular plane of movement. An isolator elastomeric member 40 is affixed to the motor 20 and also affixed to the bristle pad assembly 10, 12, 14 so that the vibratory motion induced by the motor can be translated to the bristles 10. The motor 20 is received within a cavity 42 of the bristle pad head portion sized to allow receipt of the motor 20 and the rotational movement of the offset weight 22 that causes the desired vibratory movement. The vibrations created by the off center weight are transmitted to the brush head 14 due to the motor and weight assembly being connected to the brush head by hard, stiff connections. The isolators 40 allow this motion to exist by letting the head move mostly independently from the handle by close receipt of the isolator ring lobes 50 within mating lobe cutouts 52 and the clamping of the lobes within the cutout 52 by sandwiching the lobes between the brush head 14 and upper motor cap 56. The top wall 14 and cutouts 52 are affixed hard plastic pieces ultimately supporting the bristles 10. The particular configuration of the isolator 40 is such that the lobes are closely received within the cutouts 52 and a webbing 60 includes a slot 62 for close mating reception of cap cutout 64 of fastening cap 56. In addition, the end portions of the elastomeric lobes 50 and webbing 60 are also received within handle portion cutouts 70 so that the isolator 40 effectively isolates the vibratory movement of the head portion away from the handle portion A. As can be seen with reference to FIGURES 5 and 6, the head portion assembly thus can float within the handle portion A because the vibrating actuator and motor assembly including cap 56 is spaced from the interior wall 80 of the handle portion. Except for that portion of the elastomeric ring received within the handle cutouts 70, the ring is affixed within the cutouts 70 when the upper handle half 78 is fastened on to the lower handle half 76. Other items shown within FIGURES 4 and 5 include a battery compartment 90 (although the device could also be a corded), electrical wire passage ways for the motor 92, an on-off switch 94 and a switch pad 96. A decorative cover 98 within the handle 78 covers the motor cap 56. Empirical evidence has determined that highly effective detangling can occur with the vibrating bristles operating in a frequency range between 20 - 100 Hz and more preferably between 30 - 65 Hz, with the most efficient detangling of the hair, in terms of the user effort required to pull the brush through hair, being either one of 42 Hz or 65 Hz. A61H— PHYSICAL THERAPY APPARATUS, e.g. DEVICES FOR LOCATING OR STIMULATING REFLEX POINTS IN THE BODY; ARTIFICIAL RESPIRATION; MASSAGE; BATHING DEVICES FOR SPECIAL THERAPEUTIC OR HYGIENIC PURPOSES OR SPECIFIC PARTS OF THE BODY Yet another problem with most prior vibrating hair brush devices is the communication of the vibrations through the handle to the hand of the user. The hand can function as a substantial dampening force on the vibratory movement, thereby reducing its effectiveness, and also, over time, the absorption of the vibrations by the hand can become uncomfortable and unpleasant to the user.

In the perspective view of FIGURE 6 the eccentric weight 22 is clearly seen as to how, upon rotation of the motor shaft, an eccentric bias is imposed on the motor 20 and thus also onto the isolator support member 40.

According to aspects illustrated herein, there is provided a vibrating hair brush for enhanced detangling of the user's hair having a bristle pad comprising a plurality of bristles disposed in a brush head. In this description, it should be understood that the term "vibrating" should be understood to include oscillating and the term "brush" should be understood to include embodiments that might alternatively be described as combs. The bristle pad is supported within the brush head by a vibrating motor and isolator assembly disposed for directing a vibratory movement of the motor to a bristle pad movement in a plane generally parallel to a user's scalp. The motor and isolator assembly effectively translate a circular vibratory movement of an offset weight into an elliptical movement of the bristle pad while insulating the vibration caused by the movement of the weight from a handle to the brush. The elliptical movement has a greater axis in a direction perpendicular to an extending direction of a user's hair.
