Abstract

A seat supporting assembly of a bicycle, comprises a seat tube having a shape as a wing of a plane; a seat rod received in a hollow shape of the seat tube; the seat rod having a shape as a plane wing corresponding to that of the seat tube; the seat rod having a first inclined surface and a through hole; a tightening assembly having a tightening unit and a stud; the tightening unit having a second inclined surface, an outer periphery and a stud hole; the second inclined surface having a shape corresponding to that of the first inclined surface; the outer periphery of the tightening unit being matched to an inner wall of the hollow space of the seat rod; the stud hole is corresponding to the through hole of the seat rod. The seat tube has the effect of reduction of the rotation of the seat rod.

Claims

1. A seat supporting assembly of a bicycle, comprising:

a seat rod having a non-round shape;

the seat rod having a first inclined surface;

a tightening assembly having a tightening unit;

the tightening unit having a second inclined surface corresponding to the seat rod;

wherein the non-round seat rod has the effect of reducing rotation; and

the tightening unit is slideable along the first inclined surface so that the tightening unit can be locked.

2. The seat supporting assembly of a bicycle as claimed in claim 1, further comprising:

an adjusting unit;

wherein an upper surface of the seat rod has a concave portion and a lower side of the adjusting unit has a convex portion by the engagement of the concave portion and the convex portion, the inclination of the adjusting unit is adjustable.

3. The seat supporting assembly of a bicycle as claimed in claim 1, wherein the tightening unit is made of plastic or rubber.

4. The seat supporting assembly of a bicycle as claimed in claim 1, wherein a surface of the tightening unit is a coarse surface by using sanding, forming particles or patterns.

5. The seat supporting assembly of a bicycle as claimed in claim 1, wherein the seat rod has a shape like a wing of a plane.

6. The seat supporting assembly of a bicycle as claimed in claim 1, wherein the tightening unit has a stud and an embedding unit;

the embedding unit is embedded into the tightening unit; and

the stud serves to lock the seat rod and the tightening unit so that the tightening unit slides along the first inclined surface of the seat rod to a position for locking the seat rod to the tightening unit.

8. The seat supporting assembly of a bicycle as claimed in claim 1, further comprising:

an adjusting unit;

wherein an upper surface of the seat rod has a concave portion and a lower side of the adjusting unit has a convex portion by the engagement of the concave portion and the convex portion, the inclination of the adjusting unit is adjustable.

7. A seat supporting assembly of a bicycle, comprising:

a seat tube having a shape as a wing of a plane.

a seat rod received in a hollow shape of the seat tube;

the seat rod having a shape as a wing of a plane corresponding to that of the seat tube;

the seat rod having a first inclined surface and a through hole;

a tightening assembly having a tightening unit and a stud;

the tightening unit having a second inclined surface, an outer periphery and a stud hole;

the second inclined surface having a shape corresponding to that of the first inclined surface;

the outer periphery of the tightening unit being matched to an inner wall of the hollow space of the seat rod;

the stud hole is corresponding to the through hole of the seat rod;

wherein the seat tube has the effect of reduction of the rotation of the seat rod;

the outer periphery of the tightening unit causes that the tightening unit is adhered to an inner surface of the hollow shape of the seat rod;

when screwing the stud, the tightening unit will slide along the first inclined surface so that the tightening unit will tightly resists against the seat rod.

9. The seat supporting assembly of a bicycle as claimed in claim 7, wherein a surface of the tightening unit is a coarse surface by using sanding, forming particles or patterns.

10. The seat supporting assembly of a bicycle as claimed in claim 7, wherein the tightening unit is made of plastic or rubber.
