Alloy bicycle for standing tread and sitting pedaling

Abstract

Standing and pedaling seated pedaling alloy bicycle, including front wheel, rear wheel with ratchet, hand brake handle, main frame, adjustable seat, driving sprocket and transmission chain, as an improvement: the drive shaft is also fixed on both sides of the cross pedal Barrel assembly, the car owner frame is fixed with a stop and rest device, which is composed of a pair of left pedal brackets and right pedal brackets arranged symmetrically in mirror images, the right pedal bracket has a right rest pedal, and the left pedal bracket has a left rest pedal ; The double-pedal left connecting rod and the double-pedal right connecting rod on the cross pedal assembly are vertically spaced, and the two ends of the double-pedal right connecting rod are respectively provided with a first right pedal cylinder and a second right pedal cylinder, The two ends of the double-pedal left connecting rod are respectively provided with the first left pedal cylinder and the second left pedal cylinder; the cross pedal cylinder assembly and the stop and rest device are arranged on the main frame of the car, so that the rider can alternate his feet in an efficient position Rotation, give full play to the whole body strength of the human body, and achieve labor-saving and fast results.

Description

technical field [0001] The invention relates to the field of bicycles, and the international patent classification is B62M, in particular to an alloy bicycle for standing, pedaling and sitting. Background technique [0002] Existing ordinary bicycles mostly rely on the alternating pedals of both legs to realize sports, and the alternating pedaling of left and right feet also causes transient force imbalance, and both hands can only grasp the direction and brake and assist the body to balance. The driving devices of bicycles in daily life are all of the rotary pedal type. The mechanism of alternately pedaling with both feet is like a crank linkage mechanism, which produces two dead points, the upper and lower, so it cannot perform work continuously, and there are disadvantages such as low efficiency. When the positional relationship between the pedal lever and the central axis of the sprocket is perpendicular to the ground, neither the left and right feet can generate driving...

AI Technical Summary

Problems solved by technology

In order to allow both hands to give strength to both feet, some people use the hand-cranking mechanism of the disabled on bicycles, such as the Hand-foot compound bicycle with double ratchet of US Patent No. 9,056,653 B2. The hand-cranking mechanism It brings left and right instability, and still fails to solve the inherent disadvantages of the upper and lower dead points of the roundabout pedal bicycle.
