Indicating device of a bicycle standing tube

Abstract

An indicating device of a bicycle standing tube comprises a supporting seat having buckling teeth; the supporting seat having an indication portion; the indication portion having indications; a clamping device having engaging teeth engageable to the buckling teeth of the supporting seat; each of two sides of an tooth at a center portion of the engaging teeth having a rib; arrangement of the engaging teeth being corresponding to the indications of the indication portion so that the indications of the indication portion can indicate the orientation of the engaging teeth and the ribs being used as a reference point in adjusting the orientation of the clamping sheet. The supporting seat has an indication portion and the clamping device has an arrow so that the orientation of the cushion can be indicated by the indication portion and the arrow. The user can adjust the orientation accurately by the assistance of the indication portion. Furthermore, ribs are formed on the clamping device for preventing the movement of the teeth of the supporting seat and the clamping device.

1 . An indicating device of a bicycle standing tube comprising: 
 a supporting seat having buckling teeth; the supporting seat having an indication portion; the indication portion having indications;    a clamping device having engaging teeth engageable to the buckling teeth of the supporting seat; each of two sides of an tooth at a center portion of the engaging teeth having a rib; arrangement of the engaging teeth being corresponding to the indications of the indication portion so that the indications of the indication portion can indicate the orientation of the engaging teeth and the ribs being used as a reference point in adjusting the orientation of the clamping sheet.    
   
   
       2 . The indicating device of a bicycle standing tube as claimed in  claim 1 , wherein a middle side of the indication portion has an indication of  0 ; indications of  15  degrees and  30  degrees are indicated at two sides of the indication portion.  
   
   
       3 . The indicating device of a bicycle standing tube as claimed in  claim 1 , wherein one lateral side of the engaging teeth is indicated with an arrow, the arrow points to the indications of the indication portion so as to indicate the orientation of the clamping device.  
   
   
       4 . The indicating device of a bicycle standing tube as claimed in  claim 1 , wherein the spacing of two ribs is at the uppermost teeth of the engaging teeth for receiving the supporting seat; the ribs have the function of stopping for preventing the change of the engaging angle so that the supporting seat is firmly secured to the clamping device.  
   
   
       5 . The indicating device of a bicycle standing tube as claimed in claim  1 , wherein the supporting seat comprises: 
 an upper supporting seat having at least one penetrating portion which is penetrated by a threaded hole; a lower side of the upper supporting seat has the buckling teeth;    a lower supporting seat installed at a top of a standing tube; the lower supporting seat  30  having at least one via hole; each of the via hole and a corresponding one of the threaded hole of the penetrating portions of the upper supporting seat is passed by an adjusting stud; and thus, the upper supporting seat and the lower supporting seat being combined as a supporting device.    
   
   
       6 . The indicating device of a bicycle standing tube as claimed in  claim 1 , wherein the clamping device comprising: 
 an upper clamping sheet;    a lower clamping sheet being combinable to the upper clamping sheet so as to form the clamping device; and in assembly, the clamping device is received within the supporting device.    wherein after combing the upper clamping sheet and lower clamping sheet; two sides of the clamping device are formed with a first clamping portion and a second clamping portion for clamping the supporting rods of a cushion.    
   
   
       7 . The indicating device of a bicycle standing tube as claimed in  claim 5 , wherein the clamping device comprising: 
 an upper clamping sheet;    a lower clamping sheet being combinable to the upper clamping sheet so as to form the clamping device; and in assembly, the clamping device is received within a space formed by the upper supporting seat and the lower supporting seat;    wherein after combing the upper clamping sheet and lower clamping sheet; two sides of the clamping device are formed with a first clamping portion and a second clamping portion for clamping the supporting rods of a cushion.    
   
   
       8 . The indicating device of a bicycle standing tube as claimed in  claim 7 , wherein the buckling teeth is formed at a lower side of the upper supporting seat and the engaging teeth is formed at an upper side of the upper clamping sheet so that the buckling teeth is engaged to the upper clamping sheet.  
   
   
       9 . The indicating device of a bicycle standing tube as claimed in  claim 8 , wherein two sides of the upper clamping sheet are formed with two sheets; each of two sides of each sheet at the two sides of the upper clamping sheet is formed with an ear; and lower side of each ear is formed with a recess which is formed as a first clamping portion; 
 a lower clamping sheet having a downward cambered groove at a center portion thereof; each of two sides of the lower clamping sheet is formed with a sheet which is corresponding to the sheet of the upper clamping sheet; each of two ends of each sheet at two sides of the lower clamping sheet has an ear; an upper side of each ear of the lower clamping sheet is formed as a trench which is as a second clamping portion;    wherein in assembly, the recesses and the trenches are combined as two hollow spaces for receiving the supporting rods.
