Title: Bicycle wire supporting frame

Description:
FIELD OF THE INVENTION 
     The present invention relates to bicycles, and in particular to a bicycle wire supporting frame, wherein the prior art bicycle bowl structure is improved so that the wires can be tightly engaged to a ring cover without falling out or inclination. 
     BACKGROUND OF THE INVENTION 
     Bicycles have become popular exercise devices in daily life. More and more people drive bicycles as exercise and in life. However the prior art designs of bicycles have complicated structures. In the design, the head portion of the bicycle is very important for the stability of the bicycle. 
     In the prior art design, the upper cover and wires are not firmly secured so that the wires easily fall out or tilt from the upper cover. Thereby the drive will feel uneasy and thus the interest in outdoor exercise is reduced. In one prior art, a C ring is used. An extension sheet is extended from the C ring and a wire ring is installed at one end of the extension sheet. The transversal position of the extension sheet is formed with a long through hole and a receiving hole at a middle portion thereof. The through hole is communicated to the receiving hole. The long through hole is divided into two sections at a middle section thereof. One is a small through hole with female threads and another one is a larger through hole. The extension sheet has a tighten block which can be placed in the larger through hole. The tighten block has a via hole and a front end thereof has a very small half cambered projection. A stud passes through the via hole. The head of the stud presses the tightening block to move forwards so that a recess of the tightening block has a middle portion which is placed at a tube wall of a stand tube so as to be fixed to the stand tube. 
     However in this prior art although the tightening block is used, but the wire supporting frame is still positioned from a lateral side. The function of the frame is different from a head bowl like structure. The frame will interfere the bowl like structure. For a long time, the bowl like structure will inclines. As a whole, the prior art structure is not practical and is necessary to be improved. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a bicycle wire supporting frame, wherein the prior art bicycle bowl structure is improved so that the wires can be tightly engaged to a ring cover without falling out or inclination. 
     To achieve above objects, the present invention provides a bicycle wire supporting frame, comprises an ring cover capable of being assembled to a head rod of a bicycle; the ring cover having an axial through hole for receiving the head rod; an extension portion extended from one end of the ring cover; a wire hole penetrating through the extension portion along an axial direction. An upper opening of the through hole is connected to an inclined ring for receiving a receiving lower edge of the C ring so that the head rod is tightly engaged to the through hole of the ring cover. An inner side of the through hole is formed with an inclined surface so as to receive the inclined surface of the tapered ring so that the head rod is tightly engaged to the through hole of the ring cover. A slit penetrates through the extension portion so that the wire hole is communicated to exterior through the slit so that wires of the bicycle can pass through the slit to enter into the wire hole. 
     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE INVENTION 
     In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. 
     With reference to  FIGS. 1 to 5 , the bicycle wire supporting frame of the present invention is illustrated. The present invention has the following elements. 
     An integral formed ring cover  10  is assembled to a head rod  21  of a bicycle. The ring cover  10  has the function the upper cover of a bicycle front bowl structure. A C ring  30  or a tapered ring  40  can be used to tighten the head rod  21  and the ring cover  10 . The ring cover  10  has an axial through hole  14  for receiving the head rod  21 . The C ring  30  or the tapered ring  40  serves to lock the ring cover  10  to the head rod  21 . Thus wires can be retained firmly without movement due to collision. 
     An extension portion  11  extends from one end of the ring cover  10 . A wire hole  12  penetrates through the extension portion  11  along an axial direction. A slit  13  penetrates through the extension portion  11  so that the wire hole  12  is communicated to exterior through the slit  13 . The extension portion  11  is used as a wire supporting frame so that wires of the bicycle can pass through the slit  13  to enter into the wire hole  12 . 
     Referring to  FIGS. 1 to 3 , the application of the present invention is illustrated. An upper opening of the through hole  14  is connected to an inclined ring  15  for receiving a receiving lower edge  31  of the C ring  30  so that the head rod  21  is tightly engaged to the through hole  14  of the ring cover  10 . 
     Referring to  FIGS. 4 and 5 , another application of the present invention is illustrated. The inner side of the through hole  14  is formed with an inclined surface  15  so as to receive the inclined surface  41  of the tapered ring  40  so that the head rod  21  is tightly engaged to the through hole  14  of the ring cover  10 . 
     However in the present invention, both the inclined inner surface and the inclined ring can be installed to the ring cover  10  of the present invention. 
     The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
