Description

lVlZ ^ lJlU V. Creation Instructions (1) [Technical Field to which the New Type belongs] This new type is related to a telescopic bicycle rider using a sliding member to translate the main support of the bicycle plus: improvement, especially, a front fork frame and a rear fork The relative distance of the frame, and Uz lever, to change the way of the bicycle [previous technology] W into a telescopic function. In the early days, Liaotayu was a means of transportation, and it was usually a necessary worker that was used every day. The time and technology of travelling or earning a living have reached a fairly mature level; and = car development fitness, leisure Walking, instead of every 2 heart tools, exercise. In addition, for some populations, for the intensive relocation of the country, it needs to have a storage function to respond to the time = life • V Μ Seeing almost all bicycles that can be stored It is foldable and foldable :: Although the volume of the car can be reduced considerably, it is not easy for children to use '... the fold joint is less than J hand to injure σ, and the fold joint is often damaged and damaged in the long term, which often causes Inconvenient and easy to relax ^ The telescopic bicycle (as shown in Figures 1 and 2) includes a form of sliding with a single circular crossbar of a main support frame. Although this design also achieves the telescopic function, it is a single Supported round crossbars, so sliding is likely to cause twisting. In addition, there is also a single-shaped crossbar sliding form of the main support frame. Although this design does not cause torsion, its fixing method is Pick By using-a pin hole and the bolt fixed,

Creation Instructions (2) = The style is more troublesome and if the bolt is lost, the bicycle loses its storage function [New Content], the new purpose of the collection is to propose a kind of retractable bicycle to communicate with Ii ί: ϊ ί 所 ί :: The part of the main frame of the car is used to support the two fixed seats, which are located on the front side: the front bar of the crossbar is fixed before and after the bicycle, and the front fork of the bicycle; A first perforation is provided for installing three perforations. The second perforation of the side wall and the top of the sliding member is set to move forward. The second perforation of the side wall allows the sliding member to be erected and slide on. 'And the third perforation on the top of the sliding part is to be erected after sliding; m contains ^ a fixing piece and a fixing rod, in the foregoing: two is provided with a second fixing hole on the fixing piece to install the connection Another object is to improve the problem that the conventional folding bicycles are too storage, and the folding joints are easy to pinch and damage. = Another new type-the purpose is to improve the problem of the inconvenience of the conventional telescopic pedal structure. Telescopic machine [Embodiment] As clear as the detailed description and technology of this new model ... Now with the diagrams, please refer to the "3 and 4 and -5" diagram, the telescopic mechanism 丄

V. Creation instructions (4) «Month refer to" 5, 6 — 1 and 6-2 ", when the bicycle is retracted with the telescopic mechanism 1, first release the fixing rod 1 g 1 to release the first Position, at this time, the fixed piece 150 drops downward, and is no longer in close contact with the cross bar 丄 〇 and the sliding member 13, so the cross bar 10 can be slid on the sliding member} 3, The relative position between the frame 12 and the rear fork frame 14 is reduced to the second position, and then the fixing rod 1 51 is pushed down. Since the fixing rod 1 5 1 is a cam handle, the cam mechanism is used to make The fixing piece 丄 $ 〇 is again tightly engaged to fix the position. Please refer to “Figures 7 and 8”. The new telescopic mechanism 丄 can also be modified to design the sliding member 13 on the sliding rail 20, and the coaxial parts on the top and two sides of the sliding member 1 3 are as shown in the figure. Two embodiments) Or, four bearings are provided on the coaxial sides of the two sides of the sliding member 13 (such as the third embodiment), and the sliding handle 20 is arranged on the upper and lower two sides of the sliding member 13 or The left and right sides change the relative positions between the front fork frame 12 and the rear fork frame 14 in the same manner as described above.
