Description

Folding handlebars for mountain bikes {A handle for mountain bike}

The present invention relates to a collapsible bicycle auxiliary handle, and more particularly, it is mounted on a handle tip required for steering of a bicycle to improve the mounting structure of the auxiliary handle to provide driving stability and prevent body damage of the occupant during overturning. To achieve handling and performance improvement.

In general, a bicycle is a lightweight two-wheeled vehicle that is driven by the driver's power and transmits the driving force (force) by transmitting mechanical energy such as pedals, crank mechanisms and chains to the rear wheels.

The overall configuration is a front poke (12) for fixing the front wheel (11) in front of the body frame 10 of the roughly rhombic shape as shown in Figure 1, the handle 13 and the handle necessary for the change of direction The handle stem 14 which connects the 13 and the front fork 12 is mounted,

The rear of the frame 10 is provided with a rear poke (16) for fixing the rear wheel (15) and a saddle 17 for the passenger's ride using the saddle post (18).

In addition, the chain gear 19 generating a driving force in the center of the frame 10 is provided with a crank shaft 20 and a pedal 21, and the driven chain gear 22 and the chain 23 fixed to the rear wheel 15. Is connected using).

Since the bicycle was first manufactured in the early 19th century, it has been one of the most important transportation vehicles to date, and has established itself as the basis for sports and industrial development.

Recent developments have led to changes in the transmission ratio depending on the driving conditions, to the state capable of appropriately responding to various driving conditions.

These bicycles are classified into general bicycles and special bicycles according to their purpose of use. Among them, general bicycles are single-use two-wheeled bicycles used for transportation, sports, and leisure.

Sports car, a sports and leisure bicycle with gear shift gear, Minicycle for short-distance low-speed driving used as a means of transportation in daily life, Light car for short, medium-range, low-speed driving used for daily transportation and leisure,

It is divided into utility vehicles for low speed driving used for daily transportation and transportation, and children's cars used by children of primary school and children for daily play.

Also, special bicycles are bicycles made for unusual purposes such as racing or stunts.

Road bikes, which are mainly used for road racing, track racers that are used only within bicycle stadiums, are thicker, lighter in weight, and have harder bodywork than regular bicycles for running on unpaved or mountain roads. (Mountain Bike; MTB).

Mountain bike among the bicycles classified as above was not recognized for its value since it was first introduced to Korea in 1984, but spread to the general public after the 1988 Seoul Olympics.

In recent years, most bicycles have been released in the form of mountain bikes, and are widely used not only for the specific races, but also for the general public with various clubs and especially students.

The characteristics of such a mountain bike has been described above and one of the most prominent features is the use of a straight handle,

The straight handle is used for faster and more accurate transmission of force on irregular dirt roads or mountainous terrain.

The straight handle plays a very important role among the elements constituting the mountain bike,

Material, weight, angle, length, etc. are designed to be suitable for the physical condition of the occupant to improve the performance and the driving power, as well as satisfy the light weight and vibration absorption.

This mountain bike handle guides the passenger's running direction in a streamlined form when driving straight, thereby minimizing air resistance and improving driving performance.

In order to serve as a hill climbing support point on a hilly slope, such as hills, auxiliary handles 24 are provided at both edges of the handle 13 as shown in FIG.

The auxiliary handle 24 is a tube having a diameter of the same or similar to that of the handle 13 and includes a clamping portion 25 for fastening with the handle 13 and a grip portion 26 on which a passenger's hand is seated.

The clamping part 25 is fastened with a bolt or the like after being fastened with the front end of the handle 13, and the gripping part 26 improves the gripping feeling through the bent part 27 given a predetermined angle.

The auxiliary handle 24 configured as described above is greatly emphasized in performing its role when driving straight or hill climbing driving requiring high-speed driving.

However, in addition to the limited driving conditions as described above, the use of the auxiliary handle 24 is extremely limited, which means that the use of the auxiliary handle 24 is unnecessary because only the handle 13 is mounted in normal driving.

Due to this, since the auxiliary steering wheel 24 inconveniences the occupant during normal driving, the driving stability is lowered, and thus, the supplementary steering wheel 24 needs to be supplemented with a function that can be mounted only when the auxiliary steering wheel 24 is required, such as high-speed driving or hill climbing.

However, since the auxiliary handle 24 uses the handle 13 and the bolt, it is impossible to remove and install it according to the needs of the occupant while driving, and even in the case of normal driving, a separate disassembly tool is required. It was used while accepting inconvenience while the auxiliary handle was mounted.

Therefore, the present invention was devised to solve the above-mentioned problems. By changing the fastening structure of the auxiliary handle and the handle to a variable type by a screw, it can be folded only when the occupant needs to perform the function of the auxiliary handle. Its purpose is to increase convenience.
