Abstract

The present invention provides a folding bike that can be miniaturized and lightened so that it can be easily stored and carried.

Description

Folding Bike {FOLDING TYPE BICYCLE}

Conventional bicycles have a variety of types, which are cumbersome to enumerate in detail, so when viewed by type, there are general driving, racing, cargo, and so on. As well as satisfying and still developing for the purpose of improving performance, the emergence of new products without the extraordinary performance or function will be difficult. However, what I want to point out here is not a performance or a function, but a problem of handling (HANDLING). All conventional bicycles are designed with the performance and function first, so that the performance for each use is achieved, but the storage state is used except for the use time. There is a problem with this storage condition. In other words, it is not possible to carry it functionally, so it is necessary to store it anywhere. Even if there is a dedicated storage place, it is obvious that the problem becomes serious in proportion to the demand, such as frequent theft accidents or the handling of obstacles in narrow residential areas. will be. In addition, the existing folding bicycles are easy to handle to some extent, but the weight or volume is excessive compared to the limited use (driving only), so there is no difference from the above problem.

Therefore, the bicycle having a specific use such as racing or cargo is difficult to improve the functional handling method, but all bicycles can be used for general driving, so the present invention is treated as a replacement for driving in this respect. ) To maximize the convenience and to maximize the range of use and performance to match this.

In order to realize this, the present invention prioritizes the convenience of handling over performance or function beyond the conventional common sense, and minimizes the wheels (20cm in diameter) and minimizes the accompanying parts, so as to have the same speed as the existing bicycle. With the CHAIN GEAR, the rotation ratio of the pedals and the wheels is matched, and the handle and saddle are adjustable to be applied to all the physiques, and the folding is made so that it is very easy to store or carry. This will be described in detail with reference to the accompanying drawings.

In folding after using the present invention the same speed and ride comfort as the existing bicycle, loosen the tightening bolt 18 of the upper center of the handle, pull out the handle SETTER 19, and lower the left and right handle 192, then head 12 Loosen the tightening bolt (11) of the handle, lay the handle SLEEVE (13) on the side of the fuselage, and the pedal (20) lifts up the TRIGGER (209) installed on the pedal holder (204) and the locker (208) releases the pedal. Fold each pedal 180 ° and saddle (1) first loosen the BRACE tightening bolts (4), then lower the BRACE (5), push the rear wheels in between the BRACEs, and loosen the tightening bolts of the saddle (3). Twist 90 ° and lay forward to complete the folding.

The object of the present invention is to give priority to the convenience of handling, the structure is small and light (about 4kg ±), and when folded, the volume of 20W × 30H × 70L (cm) is smaller than the travel trunk, so it is indispensable to carry or store. The convenience and proficiency of the CURVE radius is much smaller than that of conventional bicycles, which is an advantage over the narrow area, and above all, the unusual appearance that attracts adolescents' curiosity in terms of demand. It has a taste and commonality.

Claims (1)

In folding the present invention, by unwinding the tightening bolt 18 of the upper center of the handle to fold the handle 192 vertically, the handle prop 13 is loosened and then attached to the body by releasing the tightening bolt 11 and the pedal 20 protrudes Folding the saddle (1) is separated from the pedestal (5) to lie down in front of the folding bicycle is characterized in that the rear wheel is folded to fit the folded state.
