Description

Bicycle shoulder rest {SHOULDER SUPPORTER FOR BICYCLE}

The present invention relates to a bicycle shoulder support, and more particularly, to a bicycle shoulder support for holding a bicycle comfortably when riding a bicycle.

A bicycle refers to a two-wheeled vehicle that rotates its wheels by human force, and the driving principle of transmitting foot force to the rear wheel through a pedal, a crank mechanism, and a chain is a basic form of a bicycle. Bicycles that have been made more efficient by changing the gear ratio according to the speed and condition of the bicycle are becoming common.

The bike has a steering wheel, a rear wheel driven, a crank mechanism that converts the force of the rider's foot into a rotational force, transmitted to the rear wheel by a chain that is bitten by a large sprocket, and a manual brake that operates independently of the front and rear wheels. The frame that forms the body of the bike is a rhombus (or diamond) shape and is made of chromoly, titanium, aluminum, or carbon. The frame is the most important factor that determines the performance of the bicycle. It consists of a head tube, top tube, down tube, seat stay, chain stay, and shape. And length, shape and thickness depend on the frame geometry of each car body. In recent years, professional bicycles are also made of lightweight, high-carbon frames.

In Europe, where bicycle culture is traditionally developed, the world-wide bicycle races are held every year, and bicycles are used at a high level. France, Italy, and Germany have a high level of quality of bicycles, which are widely used for transportation, leisure, and sports. Japan is the most developed in Asia, and is often used for commuting and commuting in the city. Japan also has Shimano, which accounts for 60% of the global bicycle transmission market. In developing countries, it is mainly used for real life such as transportation. In developed countries, there are bicycle paths for safe driving of bicycles, but the culture of using bicycles on general roads has matured. In Korea, bicycle paths have been established in Seoul and other metropolitan cities, and mainly use bicycles for weekend leisure activities.

Bicycles provide a lot of exercise to users, and unlike cars do not generate smoke, so the government is trying to spread a lot of bicycles. However, when a user rides a bicycle for a long time, the posture is disturbed or the upper body is shaken.

In addition, depending on the type of bicycle, the user leans or stands the upper body, in particular in the case of a cycle bicycle it is difficult to get a correct posture.
