Abstract

A bike folding structure has an annular tooth device which is repeatedly used between an upper tube and a seat tube and between a lower tube and a seat tube, or between an upper tube and a seat tube above a five-way tube and between a lower tube and a seat tube below a five-way tube. The annular tooth device is retained when a plurality of teeth thereof are engaged with each other. The annular tooth device uses a locking unit to push a movable toothed ring toward and make it engage with a stationary toothed ring, such that the locking unit is secured at the seat tube tightly without loosening. When folded, the locking unit secured at the seat tube is released, making the movable toothed ring leave the stationary toothed ring to thereby separate the same. During separation, the movable toothed ring fitted into the seat tube is rotated to drive the rotation direction of tube members fixed thereon, such that a front triangle of the bike frame is folded to the rear triangle.

Description

201038435 VI. Description of the invention: [Technical field to which the invention pertains] This is a technical field of a wide variety of bicycles, especially in terms of technology. • A bicycle folding structure is provided. [Prior Art] According to the trend of leisure and holiday time, more and more a straight #self-small as a means of travel and sports, but because of the self-sufficiency:: the scope is still physical and mobility restrictions 'so can not For a long distance of rapid movement 'so 'If you want to go to the land first, then take a bicycle to travel to the land, then generally use the train, MRT, ★ ★ car to first transport the bicycle from the land to the land However, Xi: From the second exchange = too large 'so that is the use of folding bicycles developed to see the custom folding bicycles' it is not difficult to find that it is designed for single-dry frame and smaller bicycles, However, the small car, although folded, does not take up space. It is a small bicycle, so it is less comfortable, and the related folding and fixing structure is complicated and inconvenient. In the lead--the problem of the knowledge structure, how to develop the innovative structure of imagining practicality, the real consumer is looking forward to it, / Λ ', the target industry must strive to develop the goal and direction of breakthrough. With the establishment of this invention, the inventor has been engaged in the manufacture and development of related products for many years, and it is indeed practical, and the invention has been designed and carefully evaluated.彳彳古后' 3 201038435 [Summary of the Invention] Technical problem to be solved: The bicycle used in practice is too large, so it is developed to use the folding bicycle. However, it is not difficult to find the folding bicycle. It is designed for single-bar frames and smaller bicycles. However, small bicycles do not take up space after folding, but because they are small bicycles, they are less comfortable to ride and the related folding and fixing structure is complicated. It is also inconvenient to operate. Technical features for solving the problem: providing - by means of the folding structure of the self-propelled vehicle, mainly the gear ring device is repeatedly used in the self-vehicle, the early configuration, the teeth of the toothed ring device are engaged with each other, the tooth The ring-shaped mourning ehai locks the early element to push the movable tooth ring toward the fixed tooth ring, so that the eight, 〇〇< parent mouth is fixed at the time of the bite, the locking unit is fixed to the seat tube to make the bite When the pinch is not loose ^ ^ '贶, it will be fixed to the seat of the Guanghai lock, and the movable tooth ring will be separated from the fixed tooth circle. When it is separated, the sleeve is rotated. The movable tooth ring on the tube is rotated by the % of the movable toothed round, and the direction of rotation of the pipe member fixed thereto is driven, and a rim of the car can be folded into a rear triangle. Compared with the efficacy of the prior art. Too chrome a - The present invention is directed to the frame having at least the upper and lower tubes of the vehicle, so that it can be applied to a larger bicycle, and the main gear ring device is repeated. Use the upper s and the seat tube and the lower tube or the upper tube and a 201038435 to make the bite not loose. When folded, the 兮 & &&; ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ Rotating the movable tooth on the seat tube „, the rotation of the moving tooth ring drives the direction of rotation of the pipe member fixed thereto, and folds the front triangle of the frame to a rear triangle. Completing the folding of the bicycle, so it is quite simple and quick in structure and operation, and the folding or unfolding is firm and secure, and there is no need to consider the specific clamping position.
