Abstract:
1. A structure for fastening a steering tube and a handlebar of a bicycle to each other, said structure comprising: a U-shaped frame having two parallel legs which are joined together at one end to form a crown portion and said legs are each provided in proximity of a free end thereof with a through hole dimensioned to allow the passage of said steering tube, said crown portion being provided with an inner wall having a curvature to accommodate a bicycle handlebar, said frame also being provided with a receiving space located between said two legs; a steering tube rest having opposing sides and being provided on one of said opposing sides with a curvature to accommodate said steering tube, and being provided on the other of said opposing sides with a first sloping surface and a second sloping surface symmetrical to said first sloping surface, said steering tube rest being disposed in said receiving space of said frame in such a manner that said curvature of said steering tube rest comes in contact with said steering tube; a handlebar rest having opposing sides and being provided on one of its opposing sides with a curvature to accommodate said handlebar, and being provided on the other of its sides with a first sloping surface and a second sloping surface symmetrical to said first sloping surface, said handlebar rest being disposed in said receiving space of said frame in such a manner that said curvature of said handlebar rest comes in contact with said handlebar; a first press block provided with opposing sides and being provided on one of said opposing sides with a first sloping surface symmetrical to said first sloping surface of said steering tube rest, and being provided on said other of its opposing sides with a second sloping surface symmetrical to said first sloping surface of said handlebar rest, said first press block being further provided with a threaded through hole, whereby said first press block is disposed in said receiving space of said frame in such a manner that said first press block is located between said steering tube rest and said handlebar rest, and that said first sloping surface of said first press block comes in contact with said first sloping surface of said steering tube rest, and that said second sloping surface of said first press block comes in contact with said first sloping surface of said handlebar rest; a second press block provided with opposing sides and having on one of its opposing sides a first sloping surface symmetrical to said second sloping surface of said steering tube rest, and on the other of its sides with a second sloping surface symmetrical to said second sloping surface of said handlebar rest, said second press block being further provided with a stepped through hole, whereby said second press block is disposed in said receiving space of said frame in such a manner that said second press block is located between said steering tube rest and said handlebar rest, and said second press block is separated from said first press block by a distance, and that said stepped through hole of said second press block is aligned with said threaded through hole of said first press block, and that said first sloping surface of said second press block comes in contact with said second sloping surface of said steering tube rest, and that said second sloping surface of said second press block comes in contact with said second sloping surface of said handlebar rest; and a fastening bolt engaging said threaded through hole of said first press block via said stepped through hole of said second press block, whereby said bolt is fastened with said threaded through hole when said first press block and said second press block move toward each other, thereby causing said first press block in said second press block to press against said steering tube rest and said handlebar rest.
