Description

Rotating Hair Brush {ROTATING HAIR BRUSH}

The present invention relates to a hair brush, and more particularly to a rotating hair brush.

Brushes are well known as hair styling instruments. Typically, brushing is useful for improving human appearance and hair. Brushing spreads the oil on the surface of the hair along the hair, giving the hair a viscous and glossy appearance.

One type of brush that is particularly useful for styling hair is a circular brush. Typically, a circular brush includes a handle and a cylindrical extension having radially extending hairs on the handle. Hair designers typically use a circular brush with a hair dryer to make human hair styles. The hair designer places a circular brush under the head of the hair dryer and rotates the brush with fingers or wrists. Typically, a hair designer can rotate the brush about one and a half times, then pull the brush through the hair, or roll the brush half a turn again. Experienced hair designers can use curling brush technology to straighten curly hair or to straighten straight hair.

Practically it's hard to use a circular brush all over your head. To use everything, you need to put the brush at various angles. It is very difficult for a person to use a circular brush to make his or her hair style effective. Of course, hair designers have the advantage of being able to move the brush around the person who wants to make a hairstyle and put the brush in the right place. However, hair designers who spend hours spending time using circular brushes every day are prone to illnesses such as carpal tunnel syndrome with repeated movements.

Motorized roundbrushes have been developed, as shown by way of example in US Pat. No. 6,098,635 (Marino) and US Pat. No. 6,158,073 (Inventor Giovanni). The power circular brush is a user or a hair designer can place the brush in the proper position, and then brush using the power brush. However, one of the problems with power circular brushes is that the hair is entangled. These hairs tend to be entangled by being wrapped around in a brush. The hair may be wound around the brush, causing the brush head to be wound up to contact the hair surface, causing pain to the person and making it difficult to untangled hair from the brush.

In short, the present invention provides a rotating hair brush. The brush according to the invention comprises a handle. The brush body is mounted to the handle to rotate. The brush body includes a cylindrical portion having an axis, and a plurality of rows of hairs extending radially along the axis. The hair extends to a first radius about the axis. An enhancer is mounted to the first portion. The enhancer includes a lobe that extends along at least one axis. The lobe extends to a second radius about the axis. The second radius is greater than the first radius. As the brush body rotates, the hair is engaged with the user's hair, and the enhancer causes the user's hair to fall from the hair.

Hereinafter, with reference to the drawings, a brush according to the present invention will be generally described with reference to reference numeral 11 in FIG. The brush 11 includes a handle 13 and a brush body 15. The handle 13 comprises an electric motor, ie a gearbox (optional) indicated by the dotted line at 17. As shown in FIG. 1, the motor 17 is externally powered by the cord 19 or internally supplied to a battery (not shown).

The motor 17 is preferably employed at two bidirectional rotational speeds. The selector switch 21 is provided to select the brush body 15 to rotate in either a clockwise or counterclockwise direction. Toggle switch 23 is provided to allow the user to adjust the speed of rotation fast or slow. The output of the motor 17 is generally connected to the shaft and the coupling, indicated by the dashed line at 25. In the illustrated embodiment, the coupling of the shaft 25 is a hexagonal female coupling, although those skilled in the art may use other couplings.

The brush body 15 is mounted to the handle 13 to be detachable and rotated. The brush body 15 comprises a cylindrical core 27 with hairs 29 extending radially and extending along an axis in a plurality of rows. The core 27 has a predetermined radius from the rotation shaft 47. Core 27 may be made of plastic, metal or other suitable material. As shown in FIG. 2, the rows of hair 29 are arranged substantially uniformly around the circumference of the substantially cylindrical core 27. The hair 29 may be made of raw raw materials such as boar's hair, artificial materials such as plastic, or a combination of the two, all of which are natural to those skilled in the art. In the illustrated embodiment, the hairs 29 are all substantially the same length. However, the length of the hair can be varied with rows in order to provide various brushing effects.

The brush 11 preferably includes an enhancer 31 that is detachable from the core 27. As shown in FIG. 1, the enhancer 31 extends along the axial length of the core 27, which is substantially covered with hair 29. Enhancer 31 may be made of plastic, metal, or other suitable material. The metal enhancer 31 and core 27 have the advantage of maintaining heat from other heating devices of the hair dryer. In the embodiment shown in FIGS. 1 and 2, the enhancer 31 generally has a circular cross section and is mounted eccentrically with respect to the axis of rotation 47 of the core 27. As described in the detailed description below, the enhancer 31 may have an elliptical, polygonal, or other cross section.

As shown in FIG. 2, the enhancer 31 includes a pair of legs 33, 35, which engage with grooves 37, 39 extending along an axis in the core 27, respectively. have. The surface 41 of the enhancer connects between the legs 33 and 35 to cover and surround the rows of hairs 29. The surface 41 of the enhancer is formed to define a lobe 43 extending radially and outwardly.

As shown in FIG. 2, the distal end of the fur 29 lies in a first radius with respect to the axis 47 of the core 27, which is equal to the length of the fur 29 plus the radius of the core 27. Same length. The lobe 43 is located at a second radius point with respect to the axis 47. According to the invention, the second radius defined by the lobe 43 is greater than the first radius defined by the fur 29 and the core 27. The distal ends of the legs 33, 35 are located at a third radius point with respect to the axis 47. The third axis defined by the distal ends of the legs 33 and 35 is smaller than the first axis defined by the fur 29. Thus, the inclined surfaces 49 and 51 are formed between the exposed hair 29 and the lobe 43.

1 and 2, the surface of the enhancer 31 has a plurality of rows of second or fine hairs 45 thereon. The fine hair 45 is substantially shorter than the length of the basic hair 29. The fine hairs 45 may be made of raw or artificial materials in the same way as the basic hairs 29. The fine hair 45 causes the hair to be wound when the brush head 15 rotates, thereby serving to separate the hair from the basic hair 29. The separation prevents the hair from being tangled or rolled up by the base hair 29. In addition, the fine hair 45 meshes the hair with the surface of the enhancer 31 as the brush head 15 rotates, so that the hair does not scatter from the surface while using the hair dryer. However, the fine hairs 45 are so short that they do not get tangled in the hair.

3 and 4 show the core 27 which is not connected to the handle 13 together with the hair (excluded for clarity). The core 27 includes a connector member 51 which can extend in the axial direction and can be engaged with the connector 25 of the handle 13 (FIG. 1). The grooves 37, 39 extend in the axial direction from the outer end 53 of the core 27 to an inner shoulder 55 located at a point away from the inner end 57 of the core 27. The grooves 37, 39 are radially engaged with the inner ends of the legs 33, 35. Accordingly, the enhancer 31 engages the grooves 37 and 39 and the legs 33 and 35 at the end 53, respectively, and slides the enhancer 31 in contact with the shoulder 55 in the axial direction, thereby allowing the core ( 27) detachably mounted.

In addition, in FIG. 2, the hair 29 which is not covered by the enhancer 31 is engaged with the human hair. When the core 27 rotates counterclockwise, the exposed hair 29 meshes with the hair to transmit a brushing contact. As the core 31 rotates, the inclined surface 49 urges the hair to engage the outside of the circle toward the lobe 43. Lobe 43 and the fine hair 45 serves to release the hair from the hair 29. As the core 27 continues to rotate, the enhancer surface 41 moves under the hair to maintain the hair released from the exposed hair 29. As the core 27 continues to rotate, the exposed hair 29 comes back in contact with the hair and transmits a brushing motion.

In a similar manner, when the core 27 rotates clockwise, the exposed hair 29 is engaged with the hair to transmit a brushing contact. As the core 31 rotates, the inclined surface 51 urges the hair toward the lobe 45 by engaging the hair out of the circle. Lobe 43 and the fine hair 45 serves to release the hair from the hair 29. As the core 27 continues to rotate, the enhancer surface 41 moves under the hair to maintain the hair released from the exposed hair 29. As the core 27 continues to rotate, the exposed hair 29 comes back in contact with the hair and transmits a brushing motion.

In this operation, the enhancer 31 and the finer hairs 45 work together with the exposed basic hairs 29 to bond periodically and repeatedly to the hair in substantially the same way as a hair designer using a conventional circular brush. And release. Enhancer 31 and fine hair 45 prevents the brush body 15 from tangling up or curling up the hair, which is a problem with the conventional power circular brush. In addition, it can be seen that the combining, loosening and recombining operations of the brush of the present invention make the styling of the hair more smoothly than the constant rolling up of the conventional brush.

In the embodiment of FIGS. 1 and 2, the enhancer 31 is mounted so that it can be released from the core 27. By removing the enhancer 31, the brush 11 can be used as a conventional reinforced circular brush. Different shaped enhancers can be mounted to the core 27 to provide different styling effects. However, the enhancer must be fully coupled to the brush head. Such a brush head generally includes a first portion extending in the axial direction with a first radius from the axis of rotation. A plurality of first or basic hairs having a first length extend outwardly of the circle in the first portion. The enhancer is defined by a second portion extending in the axial direction, connected with the first portion, and having a second radius from the axis of rotation. The second radius is greater than the first radius. Preferably, the second radius is greater than the first radius plus the length of the basic hair. The plurality of second hairs extend outward of the second portion. Preferably, the second hair is fine hair having a length much shorter than the length of the basic hair.

The brush according to the invention has rows for several or many basic hairs and the enhancer occupies a greater or less circumference of length around the brush head. In general, a brush with an enhancer having fewer rows of basic hair and a larger circumferential length adds a body to the hair. A brush with many rows of basic hair and an enhancer with a small circumference length keeps the hair straight.

5 and 6 show a brush head with an optional enhancer 61 according to the invention. The enhancer 61 extends along the axial length of the core 27 substantially covered by the fur 29. In addition, the enhancer 61 may be manufactured using plastic, metal or other suitable material. In the embodiment shown in FIGS. 5 and 6, the enhancer 61 is generally elliptical in cross section.

As best shown in FIG. 6, the enhancer 61 comprises a pair of legs 63, 65, which are coupled to grooves 37, 39 axially hanging in the core 27, respectively. do. The surface 71 of the enhancer connects between the legs 63 and the legs 65 to cover and protect the rows of hairs 29. The surface 71 of the enhancer is formed to define lobes 73 and 75 extending out of the circle.

As described in connection with FIGS. 1 and 2, the distal end of the fur 29 is located at a first radius with respect to the axis 47 of the core 27, the radius being fur at the radius of the core 27. It is the same as adding the length of (29). Lobes 73 and 75 are each located at a second radius with respect to axis 47. According to the invention, the second radius defined by the lobes 73 and 75 is greater than the first radius defined by the fur 29 and the core 27. The distal ends of the legs 63, 65 are located at a third radius with respect to the axis 47. The third axis defined by the distal ends of the legs 63 and 65 is smaller than the first axis defined by the fur 29. Thus, slopes 79 and 81 are formed between the exposed hairs 29 and lobes 73 and 75, respectively.

As shown in Figs. 5 and 6, the enhancer surface 71 comprises a groove 83 that extends in a plurality of axial directions. The groove 83 serves to hold the hairdressing solution applied to the outer surface of the enhancer surface 71. The solution can be used to provide an improved effect on the hair. The enhancer 61 also includes an applicator strip 85 extending in the axial direction. Applicator strip 85 constitutes a foam material for holding the hairdressing solution. As the brush head rotates, the applicator strip 85 provides a solution to the hair.

7 now shows the termination of another optional brush head 91 according to the invention. The brush head 91 includes a cylindrical first portion 93 having a base hair 95 extending out of a circle in a plurality of rows. The distal end of the basic hair 95 extends outward from the rotational axis 97 of the brush head 91 to the first radius. The brush head 91 also includes an enhancer 99, which is defined by the second portion of the polygon. In this embodiment, the enhancer 99 is formed by a plane extending parallel to the axis of rotation 97 of the brush head 91. The lobes 101-107 are located between the planes of the enhancer 99. The lobes 101-107 have a constant radius from the axis 97, which is larger than the radius defined by the distal end of the base hair 95. The plane of the enhancer 99 comprises a second fine hair 109 spreading along an axis in a plurality of rows. The brush head 99 has a structure in which the first portion 93 and the enhancer are unitary. As described with respect to FIGS. 1-6, optionally, the first portion 93 is part of the removable core 99.

As such, the brush of the present invention is intended to provide substantial advantages over conventional brushes. What has been described above is to describe and describe the present invention through presently preferred embodiments. Those skilled in the art will appreciate alternative embodiments of the present invention. Although the disclosed embodiment is a power rotating brush, those skilled in the art will appreciate that the present invention is also applicable to manual, non-rotating circular brushes.
