Abstract
A trolley-like folding bicycle that mainly includes a bicycle frame, a folding device, a transmission gear, a draw bar, and a draw wheel set is disclosed. With the operation of the folding device, the present invention has a usage state and a folded state. When the present invention is in the folded state, the user can draw the trolley-like folding bicycle by simply turning the folded bicycle body upright such that the draw wheel set contacts the ground and then pulling the draw bar. At this stage, an axis formed with the draw bar is substantially perpendicular to a draw rotation axis formed with small wheels of the draw wheel set. The user can move the trolley-like folding bicycle by simply pulling the draw bar, as easily as drawing a luggage case.
Claims20
A trolley-like folding bicycle, comprising a bicycle frame, a front wheel, a rear wheel, a saddle, a folding device, and a transmission gear assembled along a bicycle body axis, wherein the bicycle frame comprises a control frame, a front half frame, a rear half frame, and a seat post, the control frame being connected to the front half frame and the front wheel, the rear half frame being connected to the seat post and the rear wheel, the transmission gear being connected to the rear half frame and the rear wheel, the folding device connecting the front half frame and the rear half frame and enabling the front half frame and the rear half frame to be folded such that the front wheel and the rear wheel move closer to each other, via the operation of the folding device, the trolley-like folding bicycle having a usage state and a folded state, characterized in that the trolley-like folding bicycle further comprises:
- a draw bar connected to the bicycle frame;
- and
- a draw wheel set comprising a first small wheel, a second small wheel, and a draw frame, the draw frame being connected to the rear half frame, the first small wheel and the second small wheel being connected to the draw frame;
- wherein when the trolley-like folding bicycle is in the folded state for being drawn, the draw bar forms a draw bar axis, the first small wheel and the second small wheel forms a draw rotation axis, and the draw bar axis is substantially perpendicular to the draw rotation axis.
The trolley-like folding bicycle as claimed in claim 14, wherein the draw bar has a quick release clamp, and the quick release clamp is for dismounting the seat post.
