Abstract
The utility model relates to a crank for bicycles. The axial cord of the utility model is changed into a curve from a straight line to enable the distance between the two pedals of a bicycle to increase by 40 mm to 140 mm. The riding angles of both legs are changed to be consistent with the angles of body dynamics all the more. So the bicycle is more labor-saving and comfortable to ride, and the edges of trousers are not easy to dirty and damage. The maintenance of a chain box is convenient.
Description
The utility model belongs to a kind of attachments of a bicycle, specifically a kind of bicycle crank.
Present bicycle crank all is the vertical bar shape, no matter the connection mode of axis and crank how, the distance in the crank outside, both sides is 140 millimeters.Human body is by bike the time, and the mechanics angle of two leg the bests is suitable abduction outward turnings, and lower limb muscles can play one's part to the full like this, indefatigability.Bicycle two cranks can not satisfy this requirement at present, and the very easily stained trousers of axis angle, the little inconvenient maintenance in chain cover space, right side.
The purpose of this utility model provides a kind of crank of bevelled laterally, increases the distance between two crank ends, promptly increases the distance of two pedals.Thereby improve the leg muscle stressing conditions, and make it to be difficult for stained trousers angle, easy to maintenance.
This is practical to be to realize like this, to have bicycle crank length now and increase the 20-50 millimeter, crooked laterally or inclination with it, it is the crank axis non-linear shape, crank and axis, pedal connection mode are constant, two mounting holes distance on two parallel planes is the 20-70 millimeter, and distance is the 180-280 millimeter between two pedals thereby make.Pedal and half breadth still are 200 millimeters.
The utility model has been compared following advantage with existing bicycle crank, meets body mechanics's angle, and it is laborsaving to ride, and is difficult for stained trousers angle, is convenient to maintenance.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model front view.
Fig. 2 is the utility model left view.
Embodiment: existing bicycle crank shape of cross section is constant, and just length increases 20-50 millimeter, press shaping die on mould then.
Claims (2)
1, a kind of bicycle crank is characterized in that crank axis is a non-rectilinear, and two mounting holes of crank are not in one plane.
2, by the described bicycle crank of claim 1, it is characterized in that mounting hole is on two parallel planes, distance is the 20-70 millimeter between the two.
