Abstract
A belt tensioner for use with a bike is provided. The bike includes a frame and a belt. The frame includes a chain stay and a seat stay having a top surface and bottom surface. The belt tensioner includes a tensioner skeleton, a roller and a tension regulator. The tensioner skeleton is pivotally connected to the chain stay or the seat stay. An included angle is formed between the tensioner skeleton and chain stay or the seat stay. The roller is pivotally connected to the tensioner skeleton and in contact with the belt. The tension regulator presses against the belt to adjust tension of the belt. The tension regulator is disposed at an end of the tensioner skeleton, and the end of the tensioner skeleton is positioned distal to the bottom surface.
Claims15
A belt tensioner applied a bike, the bike comprising a frame and a belt, the frame comprising a chain stay and a seat stay, the chain stay and the seat stay respectively having a top surface and a bottom surface, the belt tensioner comprising:
- a tensioner skeleton pivotally connected to the chain stay or the seat stay, wherein an included angle is formed between the tensioner skeleton and the chain stay or the seat stay;
- a roller pivotally connected to the tensioner skeleton and being in contact with the belt;
- and
- a tension regulator for pressing against the belt so as to adjust a tension of the belt, wherein the tension regulator is disposed at an end of the tensioner skeleton, and the end of the tensioner skeleton is positioned distal to the bottom surface, wherein a part of the belt is in contact with the tension regulator, and a vertical height of the contact part of the belt is greater than a height of the top surface of the chain stay.
A bike, comprising a frame and a belt, the frame comprising a chain stay and a seat stay, the chain stay and the seat stay respectively having a top surface, a bottom surface and a connection surface, wherein two opposing ends of the connection surface are connected to the top surface and the bottom surface, respectively, the bike further comprising:
- a belt tensioner disposed at the chain stay or the seat stay and comprising:
- a tensioner skeleton disposed at the connection surface;
- a roller pivotally connected to the tensioner skeleton and being in contact with the belt;
- and
- a tension regulator for pressing against the belt so as to adjust a tension of the belt, wherein the tension regulator is disposed at an end of the tensioner skeleton, and the end of the tensioner skeleton is positioned distal to the bottom surface, wherein a part of the belt is in contact with the tension regulator and a vertical height of the contact part of the belt is greater than a height of the top surface of the chain stay when the tension regulator presses against the belt.
