Description
Patent Application of Sivashanthan Sivapalan and Subodh Bharati For TITLE: METHOD AND APPARATUS FOR SELF-THREADING
FIELD OF THE INVENTION
This invention is related to epilation devices, specifically to such devices used for the removal of hair.
BACKGROUND OF THE INVENTION
Hair removal can be done by a variety of techniques and methods. One such method, called threading, originates from the ancient practice of the removal of hair by the use of pre-twisted thread [hereinafter "thread" includes thin wire, thin filament or any thread/wire like material] and manipulating it at four points.
The pre-twisted section of the thread is placed near the surface of the skin and is manipulated in such a way that hair is grasped and pulled from the follicle.
However this method requires a certain amount of skill. Furthermore, it is time consuming, manually intensive and difficult to do by ones-self with precision.
Thus threading usually requires the need for a second person trained in the art.
Recent attempts at self-threading apparatuses have been made however they suffer from being unwieldy and compromise precision.
SUMMARY OF THE INVENTION
The present inventors have recognized that one reason for the limitations of self-threading apparatuses in the prior art extends from the conventional threading requirement of four manipulation points.
Through our research, we have discovered a method for threading that replaces two of the four conventional manipulation points with a mechanism that twists and untwists thread using rotational motion in opposite directions.
Using this method we have invented a threading apparatus that uses a minimum of three manipulations points instead of four. This allows it to be smaller, more precise and less unwieldy than existing self-threading apparatuses. It minimizes the amount of manual labour and skills required in such a way that a person not skilled in the art can easily use this apparatuses to thread with precision.
If desired, the rotational mechanism [hereinafter "rotational mechanism" is defined as a mechanism that conveys rotational motion] of this threading apparatus may comprise an electric motor to enhance ease and precision.
In particular embodiments of this invention, a guide may be added to help select hair to be removed and further enhance precision. Other embodiments of this invention may include a magnifying glass and/or light to improve visibility and thus enhance precision. If desired, a cleaning brush to help remove dislodged hair left on the thread may also be included on particular embodiments of this invention.
Please note that each of these options provides particular advantages and can be implemented independently of the others.
These and other features as well as advantages of the invention over the prior art will become apparent from a consideration of the ensuing description and drawings.

DETAILED DESCRIPTION OF THE INVENTION
Hair removal by the conventional practice of threading uses a pre-twisted thread that is placed near the surface of the skin. Using four points of manipulation, the thread is then moved in such a way that hair is grasped and pulled from the follicle.
FIG. 1A and FIG. 1B illustrate this conventional method of threading.
Existing self-treading devices have recently been developed that follow this conventional method of four points of thread manipulation to achieve hair removal.
However, these devices suffer from being unwieldy and do not provide the same precision as hand threading by a second person.
The present inventors realized that a new method for threading that did not require the use of four manipulation points would result in numerous benefits including a device that was less cumbersome and easier to use without compromising precision.
Through our research, we have discovered, as depicted in FIG. 2A and FIG. 2B, that threading can also be achieved by replacing two of the four manipulation points with a rotational mechanism that twists and untwists thread using bidirectional rotation. Using this method we have invented a threading apparatus that requires only a minimum of three manipulation points instead of four.
FIG. 3A and FIG. 3B are diagrams of a self-threading apparatus [hereinafter referred to as "threader'] embodying the principles of the present invention. The threader comprises of a body 100. A rotational mechanism 300 comprising an electric motor 308 is substantially housed within body 100 and its trigger 103 is attached outside.
Two arms 201, 202 extend out from body 100 and are slightly bent downwards at the tips to minimize obstruction while in use. As depicted in FIG. 3C, arms 201, 202 can be rotated back into body arm enclosures 101, 102 when not in use. A
thread 304 is fastened at connection point 303 [hereinafter "connection point" is defined as a structural element to fasten thread] on rotational mechanism 303 while its endpoints are fastened to connection points 301, 302 located on arms 201, 202.
In accordance with the invention, FIG. 4A and FIG. 4B illustrate how this embodiment functions. When triggered, rotational mechanism 300 will begin to rotate in one direction causing thread 304 attached to connection point 301 to start twisting. This twisting however will increase the tension in thread 304. To relieve this tension arms 201, 202 may be made pivotable by placing springs 306 and that yield in proportion to increasing tension in thread 304.
The rotational mechanism 300 will continue to rotate in the same direction until the tension in thread 304 is not sustainable due to apparatus limitations and the end state as depicted in FIG. 4B is reached. The rotational mechanism 300 will then begin to rotate in the opposite direction thereby untwisting thread 304. As thread 304 untwists and the tension in thread 304 decreases the arms 201, 202 will return to their default state as depicted in FIG. 4A. At this point the process may be .repeated as desired.
For further illustration, this can be described mathematically as follows:
Let D be the default state of the apparatus;
Let E be the end state of the apparatus;
Let Ra be the number of rotations of the rotational mechanism 300 in direction a;
Let Rb be the number of rotations of the rotational mechanism 300 in the opposite direction b.
Let x by the number of rotations required to reach E
Then at default state D (thread 304 fully untwisted), Ra=Rb=O.
And at the end state E (thread 304 maximum twisted), Ra=x and Rb=O.
When E is reached rotational mechanism 300 will begin to rotate in the opposite direction thus untwisting the twisted thread 304. The inventors have discovered the ideal rotational scheme to be one in which rotational mechanism 300 rotates an equal number of times x in direction b from the End State E.
Thus Rb=x until default state D (thread 304 fully untwisted) is again reached.
When placed next to the skin the twisting of thread 304 will cause hair to be removed from its follicles while the untwisting of thread 304 will cause the removed hair to be dislodged from thread 304.
Other Embodiments The inventors are aware that this method for hair removal may be achieved using other embodiments of the present invention.
For example, the inventors realize other rotational schemes may be used in different embodiments. For instance, rotational schemes in other embodiments could achieve hair removal without the necessity to reach E (thread maximum twisted) and/or return to D (thread fully untwisted).
DETAILED DESCRIPTION OF THE INVENTION
Hair removal by the conventional practice of threading uses a pre-twisted thread that is placed near the surface of the skin. Using four points of manipulation, the thread is then moved in such a way that hair is grasped and pulled from the follicle.
FIG. 1A and FIG. 1B illustrate this conventional method of threading.
Existing self-treading devices have recently been developed that follow this conventional method of four points of thread manipulation to achieve hair removal.
However, these devices suffer from being unwieldy and do not provide the same precision as hand threading by a second person.
The present inventors realized that a new method for threading that did not require the use of four manipulation points would result in numerous benefits including a device that was less cumbersome and easier to use without compromising precision.
Through our research, we have discovered, as depicted in FIG. 2A and FIG. 2B, that threading can also be achieved by replacing two of the four manipulation points with a rotational mechanism that twists and untwists thread using bidirectional rotation. Using this method we have invented a threading apparatus that requires only a minimum of three manipulation points instead of four.
FIG. 3A and FIG. 3B are diagrams of a self-threading apparatus [hereinafter referred to as "threader'] embodying the principles of the present invention. The threader comprises of a body 100. A rotational mechanism 300 comprising an electric motor 308 is substantially housed within body 100 and its trigger 103 is attached outside.
Two arms 201, 202 extend out from body 100 and are slightly bent downwards at the tips to minimize obstruction while in use. As depicted in FIG. 3C, arms 201, 202 can be rotated back into body arm enclosures 101, 102 when not in use. A
thread 304 is fastened at connection point 303 [hereinafter "connection point" is defined as a structural element to fasten thread] on rotational mechanism 303 while its endpoints are fastened to connection points 301, 302 located on arms 201, 202.
In accordance with the invention, FIG. 4A and FIG. 4B illustrate how this embodiment functions. When triggered, rotational mechanism 300 will begin to rotate in one direction causing thread 304 attached to connection point 301 to start twisting. This twisting however will increase the tension in thread 304. To relieve this tension arms 201, 202 may be made pivotable by placing springs 306 and that yield in proportion to increasing tension in thread 304.
The rotational mechanism 300 will continue to rotate in the same direction until the tension in thread 304 is not sustainable due to apparatus limitations and the end state as depicted in FIG. 4B is reached. The rotational mechanism 300 will then begin to rotate in the opposite direction thereby untwisting thread 304. As thread 304 untwists and the tension in thread 304 decreases the arms 201, 202 will return to their default state as depicted in FIG. 4A. At this point the process may be .repeated as desired.
For further illustration, this can be described mathematically as follows:
Let D be the default state of the apparatus;
Let E be the end state of the apparatus;
Let Ra be the number of rotations of the rotational mechanism 300 in direction a;
Let Rb be the number of rotations of the rotational mechanism 300 in the opposite direction b.
Let x by the number of rotations required to reach E
Then at default state D (thread 304 fully untwisted), Ra=Rb=O.
And at the end state E (thread 304 maximum twisted), Ra=x and Rb=O.
When E is reached rotational mechanism 300 will begin to rotate in the opposite direction thus untwisting the twisted thread 304. The inventors have discovered the ideal rotational scheme to be one in which rotational mechanism 300 rotates an equal number of times x in direction b from the End State E.
Thus Rb=x until default state D (thread 304 fully untwisted) is again reached.
When placed next to the skin the twisting of thread 304 will cause hair to be removed from its follicles while the untwisting of thread 304 will cause the removed hair to be dislodged from thread 304.
Other Embodiments The inventors are aware that this method for hair removal may be achieved using other embodiments of the present invention.
For example, the inventors realize other rotational schemes may be used in different embodiments. For instance, rotational schemes in other embodiments could achieve hair removal without the necessity to reach E (thread maximum twisted) and/or return to D (thread fully untwisted).
The inventors also appreciate that there may be other ways to relieve the tension buildup in thread 304 as the rotational mechanism 300 rotates. One method would be to make connection point 305 elastic (hereinafter "elastic" is defined as ability of on a object or material to return to its original shape after it has been stretched, for example a spring) that lengthens and shortens in proportion to the increasing tension in thread 304. The connection points 302, 303 could also be elastic so that they yield in proportion to the increasing tension in thread 304.
Alternatively, arms 201 and 202 could be made of a resilient material that yields to some degree as tension increases.
The inventors appreciate that in some embodiments arms 201, 202 may slide into position or may fold together in different ways. Alternative the arms 201, 202 may be in a fixed position.
Other embodiments of the present invention, as depicted in FIG. 5A, may have no arms. However, it is also possible that particular embodiments of the present invention may comprise a plurality of arms, as depicted in FIG. 5B. In the alternative, FIG. SC depicts an embodiment consisting of only one arm.
The inventors also appreciate that in other embodiments of the invention, rotational mechanism 300 need not be fully enclosed within body 100. It may be partially enclosed within body 100 or totally outside. Similarly, trigger mechanism 102 need not be attached to the outside of body 100. Other embodiments may have trigger mechanism 102 attached to other parts of the apparatus such as arms 201, 202 while some embodiments may have it totally separate from the apparatus altogether.
The inventors appreciate that in other embodiments, rotational mechanism 304 of the present invention may be manual and/or mechanically powered. Furthermore, rotational mechanism 304 in some embodiments may be powered by other sources.
The inventors are aware that particular embodiments of the present invention may use multiple threads. As the preferred embodiment of the present invention use a single thread, hereinafter, "Plurality of threads" is defined as multiple threads or two loose ends of a single length of thread."
As depicted in FIG. 6, in particular embodiments of this invention, a guide 400 may be added to help select hair to be removed and further enhance precision.
Other embodiments of this invention, also depicted in FIG. 6, may include a magnifying glass 402 and/or light 401 to improve visibility and thus enhance precision.
If desired, a cleaning brush to help remove dislodged hair left on the thread may also be included on particular embodiments of this invention.
Please note that each of these options provides particular advantages and may be implemented independently of the others.
The fore going merely illustrates the principles of the invention. It is thus appreciated that others skilled in the art will be able to devise numerous other arrangements that while not shown and/or described herein, embody the principles of the invention and thus are within its spirit and scope.
