Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a bath towel hanger with strong suction discs, particularly to one quickly installable, not harming a wall surface, having multi-use. 
     A known conventional bath towel hanger  10 , shown in FIG. 1, includes a base  11  and screws  12  and a hang rod  20  as main components. The base  11  has a plurality of holes  111  in a front sidewall to receive screws  12  therein to engage screw sleeves  121  fixed in a wall W. The base  11  further has insert holes  112  in a sloped upper sidewall to receive hang rods  20  to enable a user to hang a bath towel or common towels on the hang rods  20 . 
     However, the conventional bath towel hanger  10  is secured on the wall W by first boring holes W 1  to fix the screw sleeves  121  therein for screws  12  to engage the screw sleeves  121 . So installation of the conventional bath towel hanger  10  is rather complicated and inconvenient, needing a drill to bore the holes W 1  in the wall W to fix the screw sleeves  121  for the screws  12 . Consequently the wall W is harmed and if the bath towel hanger is to be relocated, the holes W 1  remain and affect the appearance of the wall W. 
     SUMMARY OF THE INVENTION 
     The objective of the invention is to offer a bath towel hanger base with a strong suction disc that uses the suction disc to suck on the surface of a wall to quickly install the bath towel hanger and not harm the wall surface at the same time. 
     The features of the invention include a base, a suction disc, and a handling rod as main components. The base has an inner hollow space, a round opening in a rear side, a through shaft slot of a rectangular shape respectively in an upper and a bottom side aligned, and a plurality of insert holes in the upper side orderly arranged for hanging rods to insert therein. The suction disc has a sucking surface in a rear side, an annular limit wall in an intermediate portion to fit with an annular edge of the opening of the base, and a pull member on a front surface extending in the hollow space of the base. The pull member has a lateral shaft slot aligned to the shaft slots of the base and vertically crossing with the same shaft slots. The handling rod has a vertical portion passing through the shaft slots of the base and the shaft slot of the pull member and secured with a fix cap fixed on a top end of the vertical portion. The suction disc is combined with the base. The vertical portion of the handling rod has an eccentric portion located at the shaft slot of the pull member and a lateral portion extending from the lower end thereof that is located outside the bottom side of the base. The lateral portion can be swayed around to rotate vertical portion to pull the suction disc outward to suck strongly on a wall or move back to loosen from the wall.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A bath towel hanger base with a strong suction disc  40  in the present invention, as shown in FIGS. 2,  3  and  4 , includes a base  50 , a suction disc  60 , and a handling rod  70  as main components. 
     The base  50  is made integral of plastic, having an inner hollow space  51 , a round opening  52  formed in a rear side defining the hollow space  51 , a through shaft slot  53 ,  54  respectively formed in a nearly center section of an upper and a bottom side, and a plurality of insert holes  55  formed spaced apart equidistantly in a front edge of an upper side and surrounding the through shaft slot  53 . Further, the base  50  has a press connector member  56  formed to extend down from the bottom side, where the press connector member  56  has a rear flat side  561  aligned to a circumferential edge  521  of the round opening  52 ; a notch  562  formed between the rear flat side  561  and the circumferential edge  521 ; and an engage groove  563  formed in a front side. 
     The suction disc  60  is made of an elastic material, having a sucking surface  61  in a rear side, a limit annular wall  62  formed in an intermediate portion to fit with the annular edge  521  of the round opening  52  and also received in the notch  562  of the rear flat side  561 . Further, a pull member  63  is formed on a middle section of a front surface of the suction disc  60  extending in the hollow space  51  of the base  50 , consisting of an inner bottom plate  631  and two parallel, vertical, pull plates  632  on the bottom plate  631 . The inner bottom plate  631  is buried in the suction disc  60  during forming process, as shown in FIG.  4 . The two parallel pull plates  632  extend forward from the suction disc  60 , having a lateral shaft slot  633  aligned to the two shaft slots  53 ,  54  of the base  50 . 
     The handling rod  70  is L-shaped, having a straight vertical portion  71  passing through the through shaft slots  53 ,  54  of the base  50  and also through the two lateral shaft slots  633  of the pull member  63  and a fix cap  72  fixed on an end to limit the position, securing the suction disc  60  with the base  50 . The vertical portion  71  has a little eccentric push section  711  in the portion passing through the two lateral shaft slots  633 . Further, a lateral portion  73  bent in a right angle from the vertical portion  71  located a little below the base  50 , and also has a fix cap  72  fixed on an end. It is possible to sway the lateral portion  73  around. 
     Next, how to use and handle the invention is to be described. When the bath towel hanger base  40  is secured on a bathroom wall W, referring to FIG. 4, manually hold and move the lateral portion  73  of the handling rod  70  toward the rear flat side  561  under the base  50  to let a part of the lateral portion  73  engage in the engage groove  563  and be secured in that position, as shown in FIG.  7 . Meanwhile the lateral portion  73  also rotates the vertical portion  71 , which has the eccentric section  711  between the two shaft slots  633  pushing the slot wall, and the eccentric push section  711  bias rotates to pull the pull member  63  to move toward the hollow space  51 . This movement may force the circumferential edge  521  of the opening  52  push against the suction disc  60 , and the pull member  63  pulls the middle section of the suction disc  60  toward the hollow space  51  of the base  50  so that the sucking surface  61  and the wall surface W may form a vacuum hollow sucking space S to effectively and strongly suck the bath towel hanger base  40  against the wall W. After the sucking surface  61  is secured, the rear flat side  561  of the press connector member  56  also pushes the outer side of the annular wall  62  of the suction disc  60 , forming pressure to secure the suction disc  60  more stably on the wall W. 
     If the bath towel hanger base  40  is to be used for hanging towels, as shown in FIG. 6, proper towel hanging rods  90  are selected, each having one end bent vertically down to form an insert portion  91 , which can be inserted in one of the insert holes  55  of the base  50 . Then the towel-hanging rod  90  extends lateral from the base  50  for the towel  80  to hang thereon. If the base  50  is to be used for hanging a bath curtain, a shown in FIG. 7, the bath towel hanger base  40  is secured on a wall W near where a shower head is, and then a plurality of towel hanging rods  90   a  are combined with the base  40  with their bent down insert portions  91   a  inserted in the holes  55  and their outer ends provided respectively with a hook hole  92   a  to engage one of plural eye holes  1101  provided on an upper edge of the bath curtain  110 . When the insert portions  91   a  are inserted in the holes  55 , the towel hanging rod  90   a  slope upward to let the bath curtain hang down to surround a bathing space. Further, the insert portions  91   a  are pivotally inserted in the holes  55  so that the hanging rods  90   a  can sway its position to fold the bath curtain near to a wall W in case of no need or extend out for use. 
     The invention can be quickly installed or collapsed without harming a wall surface, very handy to apply, and in addition, various shapes and sizes of hanging rods may be used for different uses, making use of the strong suction disc movably sucking on a wall to secure the bath towel hanger base on the wall. 
     While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
