Abstract

The present invention relates to a bicycle and, more particularly, to a bicycle with a fixed handle which enables a user to exercise the whole body and train the physical strength by riding the bicycle. A front wheel hub is combined with a crankshaft, and the inner race (face) of a ball bearing is inserted into the left and right sides of the crankshaft which is combined with the hub. The ball bearing is inserted into a front groove of a chain stay and is covered with a cap in order to fix the outer race (face) thereof so that the front wheel and the crankshaft rotate separately. A pair of cranks combined with a pedal is combined with both sides of the crankshaft. The back wheel hub and a sprocket are combined with a back wheel shaft, and the back wheel shaft is fixed in a back groove of the chain stay with a nut in order to rotate the back wheel and the sprocket. A crank gear and the sprocket are connected with a chain to rotate. Brakes are attached to the front and back wheels. A saddle is combined with a seat tube and a brake lever is attached to the handle. Through the present invention, when riding the bicycle, a rider seats on the saddle, grasps the handle, and works the pedal. The rider can control the riding direction by moving the upper body left or right. The rider also can regulate the riding speed with the brake lever attached to the handle. Therefore, the bicycle is developed to enable exercise of the whole body.

Description

자전거 {BICYCLE}Bike {BICYCLE}

본 발명은 자전거에 관한 것으로서, 좀 더 상세하게는 손잡이(핸들)가 고정되어 있어 자전거 페달을 밟으면서 몸 상체를 좌우측으로 이동하여 방향을 조정하고, 손잡이에 부착된 브레이크 레버로 자전거의 속도를 조절하며, 운동장이나 지정된 장소에서 손잡이에서 손을 놓고 페달을 밟아 외발(한바퀴)자전거처럼 전신운동을 할 수 있도록 크랭크축에 앞바퀴와 크랭크가 결합된 자전거에 관한 것이다.The present invention relates to a bicycle, and in more detail, the handle (fixed) is fixed, while moving the upper body to the left and right while pressing the bicycle pedal to adjust the direction, the brake lever attached to the handle to adjust the speed of the bicycle It is related to a bicycle in which a front wheel and a crank are combined with a crankshaft so that the whole body can be exercised like a unicycle by releasing a hand from a handle and stepping on a pedal in a playground or a designated place.

자전거는 외발자전거, 두발자전거, 세발자전거 등의 여러 종류의 자전거가 있으며, 프레임을 다양한 모양으로 변형하여 아름답고 안전성 있는 자전거가 많이 판매되고 있다. 일반적으로 자전거는 앞바퀴와, 뒷바퀴 사이 중간에 크랭크와 페달이 결합된 두 바퀴 자전거를 많이 이용하고 있으며, 핸들과 안장이 상부에 형성되어 있어 안장에 앉아 핸들로 방향을 조정하면서 발로 페달을 밟으면 크랭크 기어가 체인으로 스프라켓을 회전되게 하여 뒷바퀴가 회전하고 자전거가 앞으로 주행하도록 하고 있다.There are many types of bicycles such as unicycles, bicycles and tricycles, and many beautiful and safe bicycles are sold by transforming the frame into various shapes. In general, a bicycle uses two-wheeled bicycles in which a crank and a pedal are combined in the middle between the front wheel and the rear wheel. The handle and the saddle are formed at the upper part, so when the user presses the pedal with the foot while adjusting the direction with the handle, the crank gear The sprockets are rotated by the chain, allowing the rear wheel to rotate and the bicycle to drive forward.

최근에는 건강을 위해서 자전거로 운동하는 사람들이 많이 증가하고 있으나, 자전거는 발로 페달을 밟아야 함으로 많은 힘이 필요하고 위험하여 부상사고가 많이 발생되고 사망사고도 늘어나고 있다. 이러한 사고를 줄이고 즐겁게 운동할 수 있도록 운동장이나 지정된 장소에서 운동할 수 있는 외발 자전거에 대하여 많은 사람들이 관심을 가지고 있으며, 외발자전거를 타는 사람들이 늘어나고 있다.In recent years, the number of people exercising on bicycles for health has increased, but since bicycles need to be pedaled with their feet, they require a lot of power and are dangerous, resulting in many accidents and deaths. Many people are interested in unicycles that can exercise on a playground or a designated place to reduce these accidents and have fun.

상기와 같은 종래의 외발 자전거는, 몸 상체를 이용하여 균형을 잡고 페달을 밟아야 하므로 운동 강도가 높고 운동효과가 좋지만, 안장이 고정되어 있지 않아 균형을 잡기가 어렵고, 브레이크가 없어 많은 연습을 해야 탈 수 있으며, 일반인이 외발 자전거를 타기에는 두렵고 넘어져서 상처를 입을 수 있어 부담스러워 하는 문제점이 있었다.In the conventional unicycle as described above, the upper body should be balanced and pedaled, so the exercise intensity is high and the exercise effect is good, but the saddle is not fixed, so it is difficult to balance, and there is no brake, so you need to practice a lot. There is a problem that the general public can be scared to fall and scared to ride a unicycle burdened.

본 발명은 상기와 같은 문제점을 해결하기 위해 개발된 것으로서, 앞바퀴 허브를 크랭크축에 결합하여 앞바퀴와 뒷바퀴가 일렬로 형성되게 하고, 앞바퀴가 결합된 크랭크축과 뒷바퀴 축에 프레임으로 연결하여 시트튜브(32)가 형성되게 하여 안장을 고정할 수 있도록 하였으며, 상부에는 손잡이를 형성하여 균형을 잡는데 도움이 되도록 하고, 손잡이에 브레이크 레버를 부착하여 자전거의 속도를 조절할 수 있도록 하였으며, 체인스테이(19) 전방에는 전방 홈(28)을 형성하고, 전방 홈 좌우측에는 관통된 구멍이 형성되게 하며, 전방 홈(28)에 대응하는 별도의 캡(27)을 준비하여 좌우측의 구멍에 볼트와 너트로 전방 홈(28)과, 캡(27)을 결합하고, 후방에는 후방 홈(29)이 형성되도록 프레임을 구성하였다.The present invention has been developed to solve the above problems, the front wheel hub is coupled to the crankshaft to form a front wheel and rear wheels in a row, the front wheel is coupled to the crankshaft and rear wheel shaft in a frame tube ( 32) to form the saddle to be fixed, the upper part to form a handle to help balance, and the brake lever attached to the handle to adjust the speed of the bicycle, chainstay (19) front The front grooves 28 are formed in the front grooves, and through holes are formed on the left and right sides of the front grooves, and a separate cap 27 corresponding to the front grooves 28 is prepared. 28), the cap 27 is coupled, and the frame is configured such that the rear groove 29 is formed at the rear.

자전거를 이용한 운동은 다른 운동에 비해 부작용이 거의 없고 체력단련은 물론 유산소 운동과 정신 건강에도 대단히 유익하다. 최근에는 주말에 자전거를 이용하여 운동을 하는 사람들도 많지만 교통비를 절약하면서 운동도 하려고 자전거로 출퇴근하는 사람들이 증가하고 있으며, 정부에서도 자전거 타기를 권장하고 자전거 도로를 많이 만들어 편리하고 안전하게 이용하도록 관리하고 있어 자전거 이용자는 계속 증가하고 있다. 본 발명의 자전거는, 운동장 또는 지정된 장소에서 운동을 목적으로 이용하도록 개발되어 기존의 자전거를 타던 사람은 누구나 탈수 있으며 외발자전거보다 안전하고, 몸 상체를 좌우측으로 이동하여 방향을 조정함으로 전신운동이 되어 체력을 증강하는데 효과가 있다.Cycling exercise has fewer side effects than other exercises and is very beneficial for aerobic exercise and mental health as well as fitness training. In recent years, many people use bicycles to exercise on weekends, but there are a growing number of people who commute by bicycle to exercise while saving money on transportation. The government encourages people to ride bicycles and makes a lot of bicycle paths to manage them conveniently and safely. Bicycle users continue to increase. The bicycle of the present invention has been developed to use for the purpose of exercise in the playground or a designated place, anyone who rides the existing bicycle is dehydrated and safer than a unicycle, by moving the upper body to the left and right to adjust the direction becomes a whole body movement It is effective in increasing stamina.
