The present invention relates generally to a motorized handheld braiding assembly and method using the same and, more particularly, relates to a braiding assembly that selectively retains a lock of hair in three adjacent, spaced-apart hair retention heads, and carries the hair retention heads on a plurality of discs that are electrically powered to rotate 360°, whereby the hair retention heads translate along a sequential figure-8 pattern for unique hair braiding arrangements.
The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
Typically, hair braiding is a method of styling hair that involves interlacing multiple strands of hair. This can create an ornamental effect for the hair, and also serves to make a fashion statement. Hairstylists often use their hands and fingers to separate and weave hair into various braided fashions. However, hands and fingers can become cumbersome when braiding hair into complex designs and dividing the hair into multiple strands. It is also difficult for non-professional hairstylists to self-braid their hair using their hands for long periods without experiencing fatigue and pain in their joints. Mechanical devices have been developed to braid the hair in the past. However, these do not always secure the hair tightly in the braiding pathway. The braiding pathway is often a simple 360° rotation that does not address more complex hair braiding requirements and supports all hair textures. It has, therefore, become desirable to develop a device or instrument for accomplishing the braiding or weaving of hair by professional hairdressers and the uninitiated. It has also become desirable to develop a method for braiding hair which is easy to teach and to use.
Therefore, a need exists to overcome the problems with the prior art as discussed above.
The invention provides a motorized handheld braiding assembly and method of braiding hair that selectively retains a lock of hair in three adjacent, spaced-apart hair retention heads.

As referenced in
A hair retaining clip on each hair retention head is height adjusted by raising and lowering to fasten and release the lock of hair. The discs are defined by three equally spaced slots 116 that are radially disposed on an outer perimeter surface. The rotational motion of the discs carries each hair retention head in a revolution while fitted in the slot of the first disc, and then slidably passes each hair retention head on to a slot in the second disc where the rotation continues in the opposite direction.
For example,
A perspective front view of the assembly is illustrated in

As
In some embodiments, a body shell cover 122 couples to upper perimeter edge 134 of the shell members 118, 120. The body shell cover 122 is disposed perpendicular to the side edges of the shell members 118, 120. The body shell cover 122 defines the upper end 302 of the handheld body 102. As illustrated in
An electrical motor 106 resides in the handheld body 102. The electrical motor 106 is electrically couplable to a power source 144 through a switch 108. The electrical motor may be AC and/or DC and may be of a direct drive, linear, servo, and/or stepper motor configuration and functionality. The electrical motor 106 may also utilize one or more linkages, cams, or cam paths to facilitate in guiding a plurality of plurality of hair retention heads 104a-c in figure-8 desired braiding path, as discussed below. In some embodiments, the power source 144 may include, without limitation, a battery, a rechargeable battery, an electrical outlet, a rechargeable dock, and an A/C-D/C converter. However, any source of energy that rotates the discs 110, 112 may be used.
Looking ahead to
The electrical motor 106 is also operably coupled to a plurality of discs 110, 112. In one non-limiting embodiment, two adjacent, equally sized discs 110, 112 are used. The electrical motor 106 is configured to cause rotation of the discs 110, 112 in opposite directions, and at a full revolution of 360°.
As discussed above, each disc is configured to rotate 360° on a disc axis 114 while fitted in the disc apertures 124, 126 of the body shell cover 122. Each disc is defined by three equally spaced slots 116 that radially disposed on an outer perimeter surface thereon.
Looking back at
Continuing, the hair retention head 104a-c has a head shaft 200 fitted within one of the three equally spaced slots 116 that form in the discs 110, 112. The discs are rotated by the electrical motor 106 while carrying the hair retention heads in the slots. The discs carry the hair retention heads 104a-c in a revolution, passing each hair retention head through slots at the perimeter surface of the discs. This allows the hair retention heads to ride both discs, and revolve in a sequential figure-8 braiding pattern; thereby braiding the hair.
As discussed above, the electrical motor 106 utilizes one or more linkages, cams, or cam paths to facilitate in guiding the hair retention heads 104a-c in the figure-8 braiding pattern 500, as discussed below. In one preferred embodiment, the plurality of plurality of hair retention heads 104a-c include three heads operably coupled to the electrical motor. Though in other embodiments, more or less than three hair retention heads may be used.
In yet another embodiment, the hair retention head comprises a hair retaining clip 204 with two opposing arms 206, 208 defining, with the head upper surface 214, a hair receiving aperture 226. The hair retention clip 204 is configured to selectively and longitudinally translate to modulate a diameter of the hair receiving aperture 226 and positionally lock with respect to the head body 202. This allows the hair retention clip to adjust in height, so as to selectively retain, and release the lock of hair.
As shown in
In another embodiment, the head body 202 comprises at least one latch 216 that is coupled thereto. The latch 216 is operably configured to lockedly engage with a portion of at least one of the two opposing arms 206, 208. In this manner, the latch positionally locks the two opposing arms 206, 208 with respect to the head body 202. The at least one latch 216 may be biased in a lockedly engaged position with respect to the portion of at least one of the two opposing arms 206, 208, through use of at least one spring 218.
This height-adjustability is possible because the two opposing arms 206, 208 of the hair retaining clip 204 are defined by multiple catch slots 232a, 232n adapted to couple and decouple to the at least one latch 216 in a snap-fit relationship. The catch slots 232a-n create a snap-fit relationship with the free ends of the arms, so as to enable the hair retaining clip 204 to incrementally height adjust. This allows the hair retaining clip 204 to be set at a desired height relative to the upper surface 214 of the head body 202. In other embodiments, the prong members of the hair retaining clip 204 are effective for coupling to the latch 216.
When employing the use of hair retaining clip 204, one or more compression fasteners are operably configured to facilitate in applying a compression force on the hair retaining clip 204, e.g., using a spring.
As such, in one embodiment, a user may depress compression fastener to enable the user to move the clip longitudinally (and linearly) and, when the user releases the compression fastener, the hair retaining clip 204 will be frictionally retained (thereby retaining the user's hair).
In one non-limiting embodiment, the opposing ends of the U-shaped hair retaining clip comprise one or more prong members. The hair retaining clip 204 may include one or more prong members that enables the hair retaining clip 204 to lock to the upper surface 214 of the head body 202, and prevent the hair retaining clip 204 from being removed longitudinally unless intentionally manipulated and/or deformed by the user. The hair retaining clips 204 may be of interchangeable and different sizes and shapes depending on the hair type desired to be retained.
As shown in
An adjacent, second hair retaining clip on a second hair retention head 104b is at a fully elevated height, so as to release the hair. And an adjacent, third hair retaining clip on a third hair retention head 104a is at a middle height, so as to loosely retain a lock of hair. To adjust the height of the hair retaining clip 204, the user may selectively translate the hair retaining clip 204 along a path (represented with arrows 900a-b) to various locked positions (as shown best in
Consequently, as the hair retention heads 104a-c follow the figure-8 braiding pattern 500, the first hair retention head 104a creates a tight weave or braiding effect. The third hair retention head 104c, having the third hair retaining clip in the middle, loosely retains the hair, forming a loose braid. The second hair retention head 104b does not carry any hair, and thus does not create a braid. Thus, the heights of the hair retention clips can be adjusted to achieve a desired braiding effect. In another example,
In alternative embodiments, elastic hair ties are used to retain the lock of hair, rather than the hair retaining clip 204. In some embodiments, the head body 202 forms a cylindrical base. The cylindrical base is defined by a cylindrical shape and a top concave portion. A plurality of flanges projects from the base. The flanges can be used to receive an elastic hair tie, or other hair retention bands known in the art. Said another way, a user may place a user's hair desired to be braided within a top concave portion before retaining it with an elastic hair tie and flanges. In other embodiments, the flanges facilitate in retaining just a user's hair without elastic hair ties.
Looking back at
In some embodiments, a spring 224 is interposed between the lower wall 220 of the head body 202 and the internal head platform 222. The spring 224 serves to bias the internal head platform 222 toward the upper surface 214. This enables the latch 216 and the catch slots 232a-n to couple and decouple in a snap-fit relationship. This biasing effect also helps retain the components of the hair retention heads 104a-c together.
As those of skill in the art will appreciate, when desired for use, the user will insert his or her hair onto or into the hair retaining clip 204 of the hair retention heads 104a-c for retention. Once retained, the user will electrically couple the electrical motor to the power source, e.g., by completing a circuit. In one embodiment, the switch may manually move the plurality of hair retention heads in the desired pattern, e.g., a figure-8 braiding pattern 500, only while the switch or button is depressed. In other embodiments, the movement of the switch to an activation position will move the plurality of hair retention heads in the desired pattern for a predetermined period of time, e.g., one minute. In said embodiments, a microcontroller may be communicatively and electrically coupled to the electrical motor and may also include pre-programmed and timed settings resident on a memory stored on a PCB board.
The user actuates operation of the discs in a rotational revolution of 360°, with each disc rotating in an opposite direction. The discs carry the hair retention heads 104a-c, passing the hair retention heads 104a-c to each other when the slots for each respective disc align. This allows the hair retention heads 104a-c to follow the figure-8 braiding pattern 500. When the user is finished braiding his or her hair, the user will electrically uncouple the electrical motor from the power source and remove the one or more clips (thereby allowing the user's hair to be effectively and safely removed).
The hair is selectively retained and carried in three adjacent, spaced-apart hair retention heads. The hair retention heads are operable to securely fasten, and release the lock of hair through one-handed operation. The hair retention heads are carried along a figure-8 pathway that creates a unique braiding pattern for the hair. The hair retention heads are carried on two rotating discs that rotate up to 360° in opposite directions.
Further, a hair retaining clip on each hair retention head is height adjusted by raising and lowering to fasten and release the lock of hair. The discs are defined by three equally spaced slots 116 that are radially disposed on an outer perimeter surface. The rotational motion of the discs carries each hair retention head in a revolution while fitted in the slot of the first disc, and then slidably passes each hair retention head on to a slot in the second disc where the rotation continues in the opposite direction.
The method 1300 may further comprise a Step 1304 of raising the height of a hair retaining clip in the hair retention heads, the hair retaining clip defined by a U-shape and a pair of free ends that axially engage the upper end of the handheld body. The U-shaped configuration of the hair retaining clip allows the user to easily lift the clip with a finger. In one possible embodiment, the hair retaining clip is biased towards the lower position, and therefore must be forcibly raised.
A Step 1306 includes lowering the height of the inserting a lock of hair into at least one of the hair retaining clips. The lock of hair, or hair-like strand, is inserted into a hair receiving aperture that forms in the hair retaining clip. After inserting the hair, the hair retaining clips are onto the hair. In some embodiments, a Step 1308 comprises lowering the height of the hair retaining clip, so as to clamp down on the lock of hair. A Step 1310 includes fastening, with a compressed fastener or a latch, the hair retaining clip to the upper end of the handheld body. The body of the hair retaining heads an interior latch that couples and decouples from the free ends of the hair retaining clip. However, in other embodiments, a compressed fastener may be used to fasten the hair retaining clip onto the hair. This fastening step is important so that the hair remains in place while being braided, weaved, or otherwise manipulated.
In some embodiments, a Step 1312 may include actuating a power switch on the handheld body, the power switch being operatively connected to an electric motor. The power switch is on the side of the handheld body within reach of a thumb or finger. A speed switch may also be available to regulate the speed of the rotation of discs; and thereby braiding speed by the hair retention heads. This may include a low, medium, high speed level selection.
A Step 1314 comprises rotating the discs in opposite direction, such that the slots in the disc periodically align during 360-degree rotation/revolution of the discs. The discs rotate in opposite directions, so as to achieve the figure-8 pattern. The method 1300 may further comprise a Step 1316 of carrying the hair retention heads along the rotatable path on one of the discs. The base of the hair retention heads coupled to the slots that form in the discs. A Step 1318 includes passing the hair retention heads between discs when the slots in the disc align during rotation. The momentum from the rotation allows the hair retention heads to be displaced between discs when the slots of the discs align.
Another Step 1320 includes rotating the hair retention heads about the first disc, and then sliding the hair retention heads to the second disc, whereby the hair retention heads follow a figure-8 braiding pattern. The method 1300 may also include a Step 1322 of braiding the hair in accordance to the figure-8 translation by the hair retention heads. The figure-8 braiding pattern 500 offers the user a unique and more complex braiding possibility for the hair. This is more than a simple twisting or rotating braiding motion can offer. This is also more effective than using the hands to raid the hair. A final Step 1324 includes raising the height of the hair retaining clip to remove the braided hair. The hair can be re-braided as many times as needed to achieve the desired fashion.
Although a specific order of executing process steps has been disclosed, the order of executing the steps may be changed relative to the order shown in certain embodiments. Also, two or more steps may be executed concurrently or with partial concurrence in some embodiments. Certain steps may also be omitted for the sake of brevity.
