BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to hair styling devices and, more particularly, to a hair styling device for assisting a user to separate clumps of hair for creating braids.
2. Prior Art
Hair braiding is one of the oldest forms of enhancing a person's physical appearance. More than simply pulling the hair back to reveal the attractive features of the face; braiding adds a decorative pattern that adds to the individual's natural beauty. Usually, hair is manually braided by a person other than the one who wants to obtain the hair style of dreadlocks. This braiding work takes extremely long time and costs too much. Also, the quality of such manually-braided hair style depends on the worker's skill totally, so that it may not be uniform. Several persons, especially among the African American population, prefer having a plurality of smaller braids that effectively cover the entirety of their head.
Some persons actually grow their hair to a sufficient length to have a professional hair stylist braid the strands into such smaller braids across their entire head. This is a rather time consuming process since the person must first grow their hair to a sufficient length, and subsequently spends a lot time having their hair braided. Due to this, it has become common practice to purchase pre-braided wigs or strands of hair that can be worn over or attached to existing strands of hair, respectively.
Today, there are a number of known braiding machines. One prior art example shows a hand-operated hair braiding machine wherein three passages through which hair is drawn are alternately rotated to braid the hair. Each of the passages is disposed in an elliptical gear. The combination of a pinion gear member with its axle disposed in a slot, and a toggling pawl, combine to effect the braiding motion of the elliptical gears. Unfortunately, such a braiding machine is limited to forming one braid at a time, thus still requiring a significant amount of time to form enough braids for covering the entirety of one's scalp.
Accordingly, a need remains for a hairstyling device in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing a device that is convenient and easy to use, provides considerable time-, cost- and space-savings, is durable in design, and is versatile in it uses. Such a device automatically measures and separates bunches of synthetic hair for individual braids in various styles. With the hairstyling device, hairdressers are more efficient and can thus conveniently earn more money. Such a device also allows a stylist to use the entirety of a package of synthetic hair, which conveniently prevents unnecessary wastage, saving the salon owner considerable supply costs.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide a hairstyling device. These and other objects, features, and advantages of the invention are provided by a hairstyling device for assisting a user to separate clumps of hair for creating braids.
The hairstyling device includes a pair of telescopically adjustable legs seated on a support surface. Each of the telescopically adjustable legs includes a linear female portion and an inverted T-shaped male portion that has a vertically registered top region slidable into the female portion. Such a male portion further has a horizontally registered bottom region directly coupled to the top region that directly engages a support surface.
A casing is directly coupled to the legs and is supported at an elevated height. Such a casing has a linear exit slot extending along a longitudinal length thereof. A stabilizing clamp is pivotally connected to an exterior of the casing. Such a stabilizing clamp extends along an entire longitudinal length of the casing and is provided with a fastening clip oppositely seated from a pivot axis thereof. The stabilizing clamp and the slot have corresponding longitudinal lengths extending parallel to each other.
A plurality of spindles are seated within the casing. Such spindles may be directly coupled to the second guide track. The spindles preferably include first, second, third and fourth spindle rows registered parallel to each other and disposed within the casing. Each of the spindle rows has a unique distance defined between adjacent spindles thereof such that each of the spindle rows effectively separate unique sized clumps of hair as the user rotates the rotary knob.
A mechanism is included for selectively raising a selected group of the spindles vertically upward and out from the casing. The spindle raising mechanism preferably includes a lever confronting an outer side of the casing that is rotatable between vertical and horizontal positions. A first drive gear is housed within the casing and is directly connected to the lever. Such a drive gear has a toothed outer periphery. A first linear guide track has a corrugated longitudinal surface directly engaged with the first drive gear. Such a first guide track contiguously lays along an interior wall of the casing and is oriented parallel to a vertical plane wherein the first guide track is vertically displaced between raised and lowered positions when the first drive gear is rotated during operating conditions.
A mechanism is included for horizontally registering the selected group of spindles with the exit slot such that remaining ones of the spindles are effectively prohibited from exiting through the exit slot, thereby automatically adjusting a thickness of the hair clumps that are separated by the selected spindles. The spindle registering mechanism may include a platform that is directly mated to the first guide track. A second linear guide track is registered orthogonal to the first linear track and is housed within the casing. A second drive gear is directly inter-locked with the second guide track. Such a second drive gear has a shaft directly connected thereto that terminates to an exterior of the casing. A rotary knob is directly connected to the shaft such that the second drive gear can effectively be linearly displaced along a horizontal path of the second guide track, thereby horizontally aligning the selected spindles beneath the slot. The first and second drive gears are preferably independently and simultaneously operable. Such first and second drive gears have corresponding fulcrum axes registered parallel to each other.
