BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a mascara brush for women to care for the eyelashes. In particular, the users select long brushes or short brushes in accordance with the length of their eyelids to use mascara brushes. The present invention relates to a mascara brush with controllable brush length of which the brush can be easily lengthened and shortened by simply turning the grip, which can be achieved by a simply structure using simple turn of a screw and linked operations. 
         [0003]    2. Description of the Related Art 
         [0004]    In general, mascara brushes are tools for women to make up the eyelashes. 
         [0005]    They are tools for make-up to make the eyelashes darker in order to stress the eyelashes to be smooth and clear such that the outlines of the eyes are emphasized. Various types of mascara brushes are required because the length and density of the eyelashes are different and the eyelids where the eyelashes are formed are also different in accordance with the users. 
         [0006]    That is, the users should use mascara brushes fitting to the length of their eyelids with the eyelashes. The users have to further apply the mascara several times, if they using short mascara brushes for make-up, and in this case, the eyelashes are likely not to be uniformly made up due to the repetitive applying. The amount of mascara is different over the eyelashes, such that it is difficult to improve the aesthetic feeling. Once the mascara is applied, it is difficult to clean and apply it again. It is preferable to prevent water from contacting the mascara because it spreads throughout the face. 
         [0007]    Therefore, it was difficult for the mascara brush makers to manufacture mascara brushes in various shapes and structures for consumer&#39;s various features, and manufacturing those various mascara brushes increases the manufacturing cost and makes mass production difficult. 
         [0008]    In order to overcome this problem in the related art, mascara brushes with controllable brush length have been developed, but users have many inconveniences due to problems in design.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0033]    Hereinafter, the configuration and the operation of the present invention are described in detail with reference to  FIGS. 1 to 11 . 
         [0034]    The present invention, as shown in  FIGS. 1 to 6 , includes: an uppermost rolling grip  10  having a vertical linking hole  11 - 1  therein and a rotation guide groove  18  formed on, the inner circumference of a rotation space  19  in the end; a middle support grip  20  having a rotary protrusion  70  and a guide protrusion  71  fitted in the rotation space and the guide groove  18  at one end, an integrated linking guide pipe  22  extending from a linking control portion A at the center therein, and a screw  21  at the other side of the rotary protrusion  70 ; and an end cover pipe  30  having a counter-screw  31  that corresponds to the screw  21  and has a mounting space  33  therein. Further, it includes an operation pole  12  passing through the rolling grip  10 , the linking hole  11 - 1  of the support grip  20 , and the linking guide pipe  22 , and a brush  50  fitted on the end fitting portion  15  of the operation pole  12 . Therefore, when they are combined and the rolling grip  10  is turned, the operation pole  12  vertically moves and the elastic brush  50  fitted on the outer circumference is lengthened and shortened. 
         [0035]    First, the present invention is composed of two types of embodiments. Both achieve the same objects in the same operation. Both are configured to lengthen and shorten the operation pole  12  by turning the grip, such that the brush  50  at the end correspondingly moves with the length increasing and decreasing. However, the structural shapes are different. Accordingly, the first embodiment of the present invention shown in  FIGS. 1 to 6  is described first, and then the second embodiment shown in  FIGS. 7 to 11  is described. 
         [0036]    The mascara brush of the first embodiment is, as shown in the figures, composed of the rolling grip  10 , the support grip  20 , the cover pipe  30 , the operation pole  12 , and the brush  50 . The uppermost portion is the rolling grip  10  in the figures, the support grip  20  is connected to the lower end of the rolling grip, and the linking guide pipe  22  integrally protrudes from the lower end of the support grip  20 . Further, the operation pole  12  and the brush  50  pass down through the linking guide pipe  22  and the cover pipe  30  is fitted to close the cover pipe  30 , the operation pole  12 , and the brush  50 , every time it needs. Obviously, mascara is filled in the cover pipe  30 , such that the brush  50  fully absorbs the mascara when the brush is positioned in the cover pipe  30 , and the brush  50  is pulled to make up the eyelashes. 
         [0037]    The operation is described in detail. In the mascara brush  100  of the first embodiment, the rolling grip  10  at the uppermost end is combined with the support grip  20 . The rotary protrusion  70  at the upper end of the support grip  20  is fitted in the guide groove  18  formed at the lower end of the rolling grip  10 , in which the guide protrusion  71  formed by increasing the diameter on the outer circumference of the rotary protrusion  70  is fitted in the guide groove  18  formed on the inner circumference of the guide groove  18 . Therefore, as a user holds and turns the rolling grip  10 , the guide protrusion  71  of the rotary protrusion  70  smoothly moves and turns along the guide groove  18 . 
         [0038]    In this operation, the upper end of the operation pole  12  is fitted in the linking hole  11 - 1  inside the rolling grip  10 . Accordingly, the operation pole  12  is turned in the same way. The brush  50  is connected to the other end, that is, the lowermost end of the operation pole  12 . Since one end of the brush  50  is fitted on the fitting portion  15  of the operation pole  12 , it can move in the same direction as the operation pole  12 . As a result, as the rolling grip  10  is turned, the operation pole  12  fitted therein is turned, such that the operation pole vertically moves with the turning due to the operation of the linking control portion A formed on the outer circumference at a side of the operation pole  12  and in the support grip  20 . The linking control portion A is configured to convert rotation into vertical movement, using screw operation. 
         [0039]    Therefore, in the mascara brush  100  of the present invention, as the rolling grip  10  at the uppermost end is turned, the operation pole  12  therein is vertically moved down and the brush  50  at the end of the operation pole is lengthened. The operation pole moves up/down along the linking guide pipe  22 , because it is accommodated in the linking guide pipe  22  of the support grip  20 . 
         [0040]    In detail, lengthening and shortening the brush  50  are described with reference to  FIG. 4 . 
         [0041]    As the rolling grip  10  at the uppermost end is turned, with the operation pole  12  and the brush  50  at the initial position (shortened position), the operation pole  12  fitted in rolling grip  10  is turned in the same way and the linking control portion A is operated by the turn. That is, the turn is converted into vertical motion. The operation moves the operation pole  12  down in the (enlarged) figure such that the operation pole  12  is vertically pushed. Obviously, the brush  50  having one end connected to the end of the linking guide pipe  22  is lengthened by the tensile force of the fitting portion of the operation pole  12  at the other end, such that brush  50  is lengthened, as shown in the (enlarged) figure. 
         [0042]    That is, in order to make up the eyelashes with the brush  50  lengthened, the user lengthens the brush  50  as shown in the (enlarged) figure, or uses the brush  50  shortened, in order to make up with a short brush. 
         [0043]    Detailed configuration and operation of the linking control portion A for implementing the operation is described. 
         [0044]    The linking control portion A of the present invention includes the linking screw portion  13  formed by forming a plurality of threads on a portion of the outer circumference of the operation pole  12  and a corresponding guider  23  formed on the inner circumference of the support grip  20 , corresponding to the linking screw portion  13 . Accordingly, as the rolling grip  10  is turned and the operation pole  12  therein is turned, the linking screw portion  13  of the operation pole  12  moves up/down on the corresponding guider  23  formed of the screw corresponding to the linking screw portion  13 , such that the brush  50  connected to the fitting portion  15  at the end of the operation pole is lengthened or shortened. 
         [0045]    The linking control portion A of the present invention is formed in very simple shape. The linking screw portion  13  is formed at a portion of the outer circumference of the operation pole  12 , as shown in the figures. Further, the corresponding guider  23  is formed in the support grip  20 . The linking screw portion  13  is formed in a protrusion shape, such as a bolt, and the corresponding guider  23  is formed in a screw groove corresponding to the linking screw portion  13 . The linking screw portion  13  vertically moves up/down while turning on the groove of the corresponding guide  23 . The vertical motion is implemented by very simple structural fitting. 
         [0046]    In this configuration, the fitting structure of the operation pole  12  and the rolling grip  10  is very important. The linking hole  11 - 1  of the rolling grip  10  is formed in a polygonal shape and a corresponding polygonal guider  11  is formed at the end of the operation pole  12  that is inserted, such that the operation pole  12  can vertically move up/down but cannot turn. 
         [0047]    The upper end (end) of the operation pole  12  fitted in the linking hole  11 - 1  formed in the rolling grip  10  has a corresponding shape. That is, although the upper guider  11  of the operation pole  12  is shown in a rectangular shape in  FIGS. 2 and 6 , a triangular or octagonal shape may be possible, other than the rectangular shape. The operation pole  12  of the present invention has the polygonal shape without a circular guider  11 , because it has to keep turning in the same was as the turn of the rolling grip  10 . Obviously, the inner circumference of the linking hole  11 - 1  may be formed in a corresponding shape such that the operation pole can be turned by the turn of the rolling grip  10 . 
         [0048]    It is important to keep the inner circumference of the linking hole and the guider  11  of the operation pole  12  completely fastened, because the operation pole  12  has to vertically move up/down. The guider  11  should be able to turn while vertically moving up/down on the inner circumference of the linking hole  11 - 1 . 
         [0049]    A structural method for lengthening and shortening the brush  50  by using the turn is described. That is, in the present invention, one end of the brush  50  is fitted on the end fitting portion  15  of the operation pole  12  and the other end is fastened to a rotary tip K rotatably connected to the end of the linking guide pipe  22 , such that the brush  50  can only be lengthened and shortened by the turn of the operation pole  12 . 
         [0050]    The fitting portion  15  that is a groove depressed inward if formed at the end of the operation pole  12 , as shown in the figures. One end of the brush  50  is fitted on the fitting portion  15 . Therefore, as the operation pole  12  vertically moves up/down, the fitting portion  15  holds and moves the brush  50  in the same direction. In this configuration, the other end of the brush  50  is connected to the end of the linking guide pipe  22  by the rotary tip K. Therefore, the end fitting portion  15  of the operation pole  12  pulls down one end of the brush  50  and the other end is connected to the end of the linking guide pipe  22 , and as a result, the brush  50  is lengthened. Obviously, the turn of the rolling grip  10  decreases the length of the brush  10 . 
         [0051]    The rotary tip K is important in this operation. The rotary tip K holds one end of the brush  50  to keep it at the position, but can turns, such that the turning motion of the operation pole  12  is absorbed and not twisted. Whether the operation pole  12  is turned left or right, the rotary tip K prevents the brush  50  from being twisted by absorbing the turning motion, such as a bearing. 
         [0052]    Alternatively, it is possible to twist the hairs of the brush  50  in the present invention. That is, in the present invention, one end of the brush  50  is fitted on the end fitting portion  15  of the operation pole  12  and the other end is fastened to a rotary tip K firmly connected to the end of the linking guide pipe  22 , such that the brush  50  can be lengthened and shortened, with the body twisted, by the turn of the operation pole  12 . 
         [0053]    Although the operation way of the rotary tip K is the same as the rotary tip K described above, according to this embodiment, as shown in  FIG. 6 , vertical motion and turning are prevented by firmly fastening the brush  50  to the linking guide pipe  22  with a fixing tip P. Since one end of the brush  50  is fitted and fixed to the end fitting portion  15  of the operation pole  12  and the other end is fastened to the end of the linking guide pipe  22  by the fixing tip P, as the operation pole  12  is turned and moved down, the length increases and the body twists. 
         [0054]    As the body of the brush  50  twists, the hairs of the brush  50  do not keep protruding uniformly and twist each other while non-uniformly protruding, such that it is possible to make up the eyelashes in various shapes. 
         [0055]    It is preferable to use an elastic material having restoring force, such as rubber, silicon, or synthetic resin, for the brush  50 , in order to easily lengthen, shorten, turn, and twist the brush  50 , as described above. The brush has elasticity to be easily lengthened when the operation pole  12  holding one end of the brush  50  pulls the brush  50 . Further, the brush  50  can be shortened and restored in the same way, when the operation pole  12  moves up to decrease the length. For this configuration, an elastic material is required for the brush  50 . 
         [0056]    Accordingly, rubber, silicon, or synthetic resin, which has elasticity, makes it easy to make up the eyelashes, and can absorb an appropriate amount of mascara is used. 
         [0057]    Further, in the present invention, as shown in  FIG. 5 , a scale  62  is marked on the outer circumference of the rolling grip  10  and a reference bar  61  is formed on the outer circumference of the support grip  20 . Therefore, it is possible to check the amount of increase and decrease in length of the brush  50 . As the rolling grip  10  is turned, the brush  50  is lengthened or shortened. It is possible to see the increase or decrease by the scale and the reference bar. 
         [0058]    It is possible to accurately measure and adjust the length of the brush  50  by fitting the scale on the rolling grip  10  to the corresponding reference bar  61  of the support grip  20 . Therefore, it is possible to more accurately estimate the length of the brush  50  in this way. 
         [0059]    According to the scope of the first embodiment of the present invention, a rubber pad  40  is provided on the outer circumference of the rolling grip  10  to prevent sliding. As shown in  FIGS. 1 to 6 , the user holds the support grip  20  of the grip with the left or right hand and turns the rolling grip  10  with the fingers of the other hand. In this operation, the user can easily turn it by holding the rubber pad  40  on the outer circumference of the rolling grip  10 . 
         [0060]    Next, the second embodiment of the present invention is described. The second embodiment achieves substantially the same objects and effects as the first embodiment. The configuration is slightly different and the operational way is different. That is, the rolling grip  10  is formed at the uppermost end and the user holds the support grip  20  under the rolling grip and turns the rolling grip  10  with the fingers of the other hand in the first embodiment described above, but in the second embodiment, the operation pole  12  is lengthened and shortened by turning the rolling grip  10  while holding the support grip  20  at the uppermost end. Accordingly, the second embodiment is described in consideration of this difference. 
         [0061]    A mascara brush according to the second embodiment, as shown in  FIGS. 7 to 11 , includes: an uppermost support grip  10  having a vertical linking hole  11 - 1  therein, a rotation guide groove  18  formed on the inner circumference of a rotation space  19  in the end, and a linking control portion A extending and protruding down from the linking hole  11 - 1 ; a middle support grip  20  having a rotary protrusion  70  fitted in the rotation space  19  and the guide groove  18 , and a guide protrusion  71  formed on the outer circumference, at one end, an integrated linking guide pipe  22  extending and communicating with an operation space  27  at the center therein, and a screw portion  21  at the other side of the rotary protrusion  70 ; and an end cover pipe  30  having a counter-screw  31  that corresponds to the screw  21  and has a mounting space  33  therein. Further, it includes an operation pole  12  passing through the support grip  10 , the linking hole  11 - 1  of the rolling grip  20 , and the linking guide pipe  22  and including the linking control portion A, and a brush  50  fitted on the end fitting portion  15  of the operation pole  12 . Therefore, when the rolling grip  20  is turned, the operation pole  12  vertically moves and the elastic brush  50  fitted on the outer circumference is lengthened and shortened. 
         [0062]    The mascara brush of the first embodiment is, as shown in the figures, composed of the supporting grip  10 , the rolling grip  20 , the cover pipe  30 , the operation pole  12 , and the brush  50 . The uppermost portion is the support grip  10  in the figures, the rolling grip  20  is connected to the lower end of the rolling grip, and the linking guide pipe  22  integrally protrudes from the lower end of the rolling grip  20 . Further, the operation pole  12  and the brush  50  pass down through the linking guide pipe  22  and the cover pipe  30  is fitted to close the cover pipe  30 , the operation pole  12 , and the brush  50 , every time it needs. Obviously, mascara is filled in the cover pipe  30 , such that the brush  50  fully absorbs the mascara when the brush is positioned in the cover pipe  30 , and the brush  50  is pulled to make up the eyelashes. 
         [0063]    The operation is described in detail. In the mascara brush  100  of the second embodiment, the support grip  10  at the uppermost end is combined with the rolling grip  20 . The rotary protrusion  70  at the upper end of the rolling grip  20  is fitted in the guide groove  18  formed at the lower end of the support grip  10 , in which the guide protrusion  71  formed by increasing the diameter on the outer circumference of the rotary protrusion  70  is fitted in the guide groove  18  formed on the inner circumference of the guide groove  18 . Therefore, as a user holds and turns the rolling grip  20 , the guide protrusion  71  of the rotary protrusion  70  smoothly moves and turns along the guide groove  18 . 
         [0064]    In this configuration, the operation pole  12  is positioned in the operation space  27  inside the rolling grip  20 . Accordingly, the operation pole  12  is turned in the same way. The brush  50  is connected to the other end, that is, the lowermost end of the operation pole  12 . Since one end of the brush  50  is fitted on the fitting portion  15  of the operation pole  12 , it can move in the same direction as the operation pole  12 . As a result, as the rolling grip  20  is turned, the operation pole  12  fitted therein is turned, such that the operation pole vertically moves with the turning due to the operation of the linking control portion A formed on the outer circumference at a side of the operation pole  12  and in the rolling grip  20 . The linking control portion A is configured to convert rotation into vertical movement, using screw operation. 
         [0065]    Therefore, in the mascara brush  100  of the present invention, as the rolling grip  20  is turned, the operation pole  12  therein is vertically moved down and the brush  50  at the end of the operation pole is lengthened. The operation pole moves up/down along the linking guide pipe  22 , because it is accommodated in the linking guide pipe  22  of the support grip  10  and the rolling grip  20 . 
         [0066]    In detail, lengthening and shortening the brush  50  are described with reference to  FIGS. 7 and 9 . 
         [0067]    As shown in  FIG. 9 , as the rolling grip  20  at the middle portion is turned, with the operation pole  12  and the brush  50  at the initial position (shortened position), the operation pole  12  fitted in rolling grip  20  is turned in the same way and the linking control portion A is operated by the turn. That is, the turn is converted into vertical motion. The operation moves the operation pole  12  down in  FIG. 7  such that the operation pole  12  is vertically pushed. Obviously, the brush  50  having one end connected to the end of the linking guide pipe  22  is lengthened by the tensile force of the fitting portion  15  of the operation pole at the other end, such that brush  50  is lengthened, as shown in  FIG. 9 . 
         [0068]    That is, in order to make up the eyelashes with the brush  50  lengthened, the user lengthens the brush  50  as shown in  FIG. 7 , or uses the brush  50  shortened, as shown in  FIG. 9 , in order to make up with a short brush. 
         [0069]    Detailed configuration and operation of the linking control portion A for implementing the operation is described. 
         [0070]    The linking control portion A of the present invention includes the linking screw portion  13  formed by forming a plurality of threads on a portion of the outer circumference of the operation pole  12  and a corresponding guider  23  formed on the inner circumference and communicating with the linking hole  11 - 1  of the support grip  10 , corresponding to the linking screw portion  13 . Accordingly, as the rolling grip  20  is turned and the operation pole  12  therein is turned, the linking screw  13  of the operation pole  12  moves up/down on the corresponding guider  23  formed of the screw corresponding to the linking screw  13 , such that the brush  50  connected to the fitting portion  15  at the end of the operation pole  12  is lengthened or shortened. 
         [0071]    The linking control portion A of the present invention is formed in very simple shape. The linking screw  13  is formed at a portion of the outer circumference of the operation pole  12 , as shown in the figures. Further, the corresponding guider  23  is formed in the rolling grip  20 . The linking screw portion  13  is formed in a protrusion shape, such as a bolt, and the corresponding guider  23  is formed in a screw groove corresponding to the linking screw portion  13 . The linking screw portion  13  vertically moves up/down while turning on the groove of the corresponding guide  23 . The vertical motion is implemented by very simple structural fitting. 
         [0072]    In this configuration, the fitting structure of the operation pole  12  and the rolling grip  20  is very important. The operation space  27  of the rolling grip  20  is formed in a polygonal shape and a corresponding polygonal guider  17  is formed on the outer circumference of the operation pole  12  that is inserted, such that the operation pole  12  can vertically move up/down but cannot turn. 
         [0073]    A portion of the outer circumference of the operation pole  12  fitted in the operation space formed in the rolling grip  20  has a corresponding shape. That is, although the guider  17  of the operation pole  12  is shown in a rectangular shape in  FIG. 11 , a triangular or octagonal shape may be possible, other than the rectangular shape. The operation pole  12  of the present invention has the polygonal shape without a circular guider  17 , because it has to keep turning in the same was as the turn of the rolling grip  20 . Obviously, it is possible to turn the operation pole  12  with the turn of the rolling grip  20 , by correspondingly forming the inner circumference of the operation space. 
         [0074]    It is important to keep the inner circumference of the operation space  27  and the guider  17  of the operation pole  12  completely fastened, because the operation pole  12  has to vertically move up/down. The guider  147  should be able to turn while vertically moving up/down on the inner circumference of the operation space  27 . 
         [0075]    A structural method for lengthening and shortening the brush  50  by using the turn is described. That is, in the present invention, one end of the brush  50  is fitted on the end fitting portion  15  of the operation pole  12  and the other end is fastened to a rotary tip K rotatably connected to the end of the linking guide pipe  22 , such that the brush  50  can only be lengthened and shortened by the turn of the operation pole  12 . 
         [0076]    The fitting portion  15  that is a groove depressed inward if formed at the end of the operation pole  12 , as shown in the figures. One end of the brush  50  is fitted on the fitting portion  15 . Therefore, as the operation pole  12  vertically moves up/down, the fitting portion  15  holds and moves the brush  50  in the same direction. In this configuration, the other end of the brush  50  is connected to the end of the linking guide pipe  22  by the rotary tip K. Therefore, the end fitting portion  15  of the operation pole  12  pulls down one end of the brush  50  and the other end is connected to the end of the linking guide pipe  22 , and as a result, the brush  50  is lengthened. Obviously, the turn of the rolling grip  20  decreases the length of the brush  50 . 
         [0077]    The rotary tip K is important in this operation. The rotary tip K holds one end of the brush  50  to keep it at the position, but can turns, such that the turning motion of the operation pole  12  is absorbed and not twisted. Whether the operation pole  12  is turned left or right, the rotary tip K prevents the brush  50  from being twisted by absorbing the turning motion, such as a bearing. 
         [0078]    Alternatively, it is possible to twist the hairs of the brush  50  in the present invention. That is, in the present invention, one end of the brush  50  is fitted on the end fitting portion  15  of the operation pole  12  and the other end is fastened to a rotary tip K firmly connected to the end of the linking guide pipe  22 , such that the brush  50  can be lengthened and shortened, with the body twisted, by the turn of the operation pole  12 . 
         [0079]    Although the operation way of the rotary tip K is the same as the rotary tip K described above, according to this embodiment, as shown in  FIG. 11 , vertical motion and turning are prevented by firmly fastening the brush  50  to the linking guide pipe  22  with a fixing tip P. Since one end of the brush  50  is fitted and fixed to the end fitting portion  15  of the operation pole  12  and the other end is fastened to the end of the linking guide pipe  22  by the fixing tip P, as the operation pole is turned and moved down, the length increases and the body twists. 
         [0080]    As the body of the brush  50  twists, the hairs of the brush  50  do not keep protruding uniformly and twist each other while non-uniformly protruding, such that it is possible to make up the eyelashes in various shapes. 
         [0081]    It is preferable to use an elastic material having restoring force, such as rubber, silicon, or synthetic resin, for the brush  50 , in order to easily lengthen, shorten, turn, and twist the brush  50 , as described above. The brush has elasticity to be easily lengthened when the operation pole  12  holding one end of the brush  50  pulls the brush  50 . Further, the brush  50  can be shortened and restored in the same way, when the operation pole  12  moves up to decrease the length. For this configuration, an elastic material is required for the brush  50 . 
         [0082]    Accordingly, rubber, silicon, or synthetic resin, which has elasticity, makes it easy to make up the eyelashes, and can absorb an appropriate amount of mascara is used. 
         [0083]    Further, in the present invention, as shown in  FIG. 10 , a scale  62  is marked on the outer circumference of the rolling grip  20  and a reference bar  61  is formed on the outer circumference of the support grip  10 . Therefore, it is possible to check the amount of increase and decrease in length of the brush  50 . As the rolling grip  20  is turned, the brush  50  is lengthened or shortened. It is possible to see the increase or decrease by the scale and the reference bar. 
         [0084]    It is possible to adjust the length of the brush  50  by fitting the scale  62  on the rolling grip  20  to the corresponding reference bar  61  of the support grip  10 . Therefore, it is possible to more accurately estimate the length of the brush  50  in this way. 
         [0085]    According to the scope of the second embodiment of the present invention, a rubber pad  40  is provided on the outer circumference of the rolling grip  20  to prevent sliding. As shown in  FIGS. 7 to 11 , the user holds the support grip  10  at the end of the grip with the left or right hand and turns the rolling grip  20  at the middle portion with the fingers of the other hand. In this operation, the user can easily turn it by holding the rubber pad  40  on the outer circumference of the rolling grip  20 .
