Description

M248709

[Technical Field of New Type] This creation is about a telescopic anti-twist structure. [Prior art] or socket pipe fittings in combined bicycles The frame structure of bicycles can be divided into solid and combined types. Fixed type, folding type, telescopic type and fixed tube and rear fork are integrated. Due to its limitations, it is easy to love the outer storage, the packaging is longer, and the fixed-type bicycle is not carried on the bicycle fixed frame, which can affect the frame such as the traveling frame. The advantages are that it is inconvenient in terms of design and the weight of the container. Some vehicles have a stationary frame, but the non-car safety structure is a head tube, front fork, upper tube, and a friend that are welded to each other in a permanent bonding manner. The frame has a strong structural strength and an appearance shape such as a diamond frame is easier to be used. "Consumption" and its disadvantages are the excessive accumulation of packaging materials and the substantial increase in costs such as transportation, especially its light weight (especially electric bicycles), which makes it difficult for consumers to use this general structure of bicycles to ride in the countryside. And fitness functions; although there are currently on the market for users to mount bicycles on the roof of the vehicle, but are more annoying or welded in the operation of setting up the bicycle, which is unacceptable to those who do not accept it and cause the length of the carriage to be stored and moved, which affects The tail of various types of vehicles is cumbersome, and the foldable frame structure is mainly provided at least one in the middle of the frame to make the frame Front and rear cross members for folding hinge fold, which advantage can be shortened by folding the frame length, may be utilized to facilitate collection and cars carry the folding bicycle riding to the outer Bin. The disadvantage is that the strength of the frame structure is not good, and it must be reinforced with the help of a reinforcing structure, otherwise it is easy to produce breaks at the folding hinge.

GA031002.ptd Page 5 M248709 V. Creation Instructions (2) '~' 一 '-At the same time, its appearance is restricted by folding hinges and folding directions, etc. It is not easy to design an appearance that is easy to be accepted and loved by consumers; In addition, In terms of packaging material volume, although a folding bicycle can be shortened after being folded, its overall width is greatly increased. Therefore, it cannot effectively reduce the packaging material volume after being folded. For manufacturers and distributors, whether they are stored or transported, It still has its inconvenience; at the same time, the weight of a folding bicycle is heavier than that of a regular stationary bicycle, and its handling is not as good as a stationary bicycle. Telescopic bicycles are made by cutting a frame tube (especially the upper tube) into two sections, and making the two sections of pipe fittings relatively telescopically telescoping with each other to extend or shorten the length of the frame. It is easy to store and use the luggage compartment of the Erhu car for riding in the countryside. & As for the combined bicycle for which the applicant of this case filed multiple patent applications, the frame structure is mainly divided into a front frame and a rear frame separated from each other, and the front and rear frames are assembled into at least one assembly structure. Complete frame structure; it also has the advantages of good structural strength, unconstrained appearance and design, fast and easy assembly, better transportability by dispersing the weight of the vehicle, truly reducing the amount of outfitting materials, and being able to use the general luggage compartment for riding to the countryside. 0 The technical means of telescopic and combination bicycles are equipped with a structure that is connected to each other. When the bicycle is' generating a radial component force that causes the front of the bicycle to roll, the user must balance the roll component to smoothly ride the bicycle. The two-stage pipe or tube fittings used by the user to step on the pedal due to the axial component force of the user riding on the pedal and the need to practice before they can drive in their body posture; in telescopic and combination The self-generated radial component of force will make each other
