본 발명은, 자전거에 관한 것으로서 상세하게는 자전거 핸들 부분이 전륜휠 축을 중심으로 전후 회동 가능하도록 구성하되, 사용자가 핸들을 전후로 회동시킬 때 그 운동력이 자전거의 휠축으로 전달되도록 함으로써, 사용자의 상체 근력 강화 운동 제공은 물론, 자전거 전륜축으로 자전거가 전방측으로 전진되도록 하는 전진운동력이 동시에 제공되도록 함으로써, 사용자에게 전신 운동이 가능한 전후 회동 가능한 핸들을 갖는 자전거에 관한 것이다.The present invention relates to a bicycle, and in particular, the bicycle handle portion is configured to be able to rotate back and forth around the front wheel shaft, but when the user rotates the handle back and forth, so that the exercise force is transmitted to the wheel shaft of the bicycle, the user's upper body strength The present invention relates to a bicycle having a front and rear pivotable handle capable of providing a whole body movement to a user by providing a reinforcement exercise, as well as providing a forward movement force that allows the bicycle to move forward to the front side of the bicycle front wheel shaft.

일반적으로, 자전거는 사람이 양측 페달을 밟아 회전시키면서 동력을 발생하여 이송 가능하도록 하기 위한 이송수단인바, 상기 페달에 의해 회전되는 스프로킷은 체인에 의해 후륜측을 회전시켜 자전거가 전진 가능하도록 구성하고 있음은 주지된 바와 같다.In general, a bicycle is a conveying means for allowing a person to generate power while being transported by stepping on both pedals, and the sprocket rotated by the pedal rotates the rear wheel side by a chain so that the bicycle can move forward. Is as well known.

즉, 전륜 및 후륜이 프레임에 의해 회전 가능하도록 고정되는 상태에서, 사용자가 후륜과 체인에 의해 연결되는 페달을 회동시켜 전진 운동력을 얻도록 하고 있는데, 이러한 자전거는 연료를 필요로 하지 않아 공해 유발이 전혀 없고 환경 친화적임은 물론, 근거리 이송수단으로 애용되고 있으며 운동기구로도 활용되고 있다.In other words, while the front and rear wheels are fixed to be rotatable by the frame, the user rotates the pedals connected by the rear wheel and the chain to obtain forward momentum. These bicycles do not require fuel and thus do not cause pollution. It is not used at all and is environmentally friendly, and is used as a short distance transportation means and is also used as an exercise equipment.

그러나, 이러한 통상의 자전거는 사용자의 다리 근력만을 사용하게 되므로, 편중된 운동효과만 기대할 수 밖에 없는 단점이 있으며, 상체 운동이나 팔 운동은 전혀 진행되지 않게 되므로, 전신운동으로서의 효과를 달성하는데는 상당히 미흡한 실정이다.However, since such a normal bicycle uses only the leg muscles of the user, there is a disadvantage that only the biased exercise effect can be expected, and since the upper body exercise or the arm exercise does not proceed at all, the effect as a whole body exercise is quite significant. It is insufficient.

따라서, 이러한 문제점 등을 해결하기 위해 즉, 사용자의 팔운동이나 상체 근력 운동 등을 증가시키기 위한 구성으로서, 대한민국 특허등록 제 579530 호인 "핸들조작에 의해 구동되는 자전거"가 등록 개시되어 있다.Therefore, to solve such a problem, that is, as a configuration for increasing the user's arm movement, upper body strength exercise, etc., Korean Patent Registration No. 579530, "Bicycle driven by the handle operation" has been registered.

위 특허의 경우, 자전거의 핸들을 전륜을 지지하는 프레임측을 따라 밀거나 당겨주도록 함으로써 전륜의 구동이 가능하도록 하여, 다리의 회전 운동과 팔을 이용한 상체운동을 동시에 수행 할 수 있는 자전거를 제공하고 있다.In the case of the above patent, by driving the front wheel by pushing or pulling the handle of the bicycle along the frame side supporting the front wheel, to provide a bicycle that can perform the rotational movement of the leg and the upper body movement using the arm at the same time have.

그러나, 위 특허의 자전거에 의한 구성은 사용자가 자전거의 안장에 앉은 상태에서, 핸들을 푸싱하듯이 하방으로 밀은 후, 재차 상방으로 들어올리는 동작을 반복 수행하여야 되는데 현재 사용되는 자전거의 구조에 있어서 핸들과 안장간의 거리가 상당히 이격되는 경우가 많아, 사용자가 자전거의 안장에 앉은 상태에서 핸들을 하방으로 미는 동작 및 상방으로 들어올리는 동작이 용이하지 않게 되는 문제점이 있다.However, in the bicycle configuration of the above patent, the user must sit down on the saddle of the bicycle, push the handle downwards as if pushing the handle, and then repeatedly lift upwards. In many cases, the distance between the handle and the saddle is considerably spaced apart, and the user may not easily move the handle downward and lift upwards while sitting on the saddle of the bicycle.

한편, 이와는 달리 공개특허공보 특 2003-39955 호의 경우, 핸들을 뽑아서 프레임 측면으로 구비되는 파이프측으로 삽입 고정한 후, 노 젓듯이 앞뒤로 당겼다 물리는 작용을 반복 수행하도록 하고, 이와 연동되는 연결바(연간)가 좌우 왕복 운동에 의해 크랭크를 회전운동으로 전환케하여, 이와 연동되는 체인을 통하여 후륜을 회전하도록 하므로써, 자전거의 전체적 전진 운동력을 얻을 수 있도록 하였다.On the other hand, in the case of Patent Publication No. 2003-39955, the handle is pulled out and inserted into the side of the pipe provided to the frame side, and then pulled back and forth like a rowing to repeatedly perform the snapping action, the connecting bar (yearly) By converting the crank to the rotary motion by the left and right reciprocating motion to rotate the rear wheel through the chain associated with it, the overall forward movement of the bicycle can be obtained.

그러나, 상기한 특허공개 특 2003-39955 호는 핸들을 착탈한 후 핸들 프레임측으로 구비되는 파이프에 삽입하도록 하고 있어, 핸들 중심이 사용자의 측면부로 옮겨지게 되는바 즉, 안장과 핸들간 중심이 어긋나게 되어 핸들을 노젓듯이 작동하게 되면 사용자의 상체가 뒤틀린 상태에서 운동을 하게 되므로 사용자의 허리에 심한 통증을 유발시킬 수 있으며, 안정적 자세에 의한 운동 효과를 기대하기 어렵게 되는 문제점이 있다.However, the above-mentioned Patent Publication No. 2003-39955 allows the handle to be inserted into a pipe provided to the handle frame side after detaching the handle, so that the handle center is moved to the side surface of the user, that is, the center between the saddle and the handle is shifted. When operating the handle like a rowing, the user's upper body is in a twisted state to exercise, causing severe pain in the user's waist, there is a problem that it is difficult to expect the exercise effect by a stable posture.

따라서 본 발명은 상기한 문제점을 해결하기 위해 안출한 것으로서, 자전거를 이용하여 근거리 이동시, 사용자의 하체 근력 강화 운동은 물론이거니와 상체의 근력 운동 효과를 제공하도록 하는데 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, the purpose of providing a muscle exercise effect of the upper body as well as the lower body strength strengthening exercise of the user when moving a short distance using the bicycle.

따라서, 상기한 목적을 달성하기 위한 본 발명은, Therefore, the present invention for achieving the above object,

통상의 자전거(100) 구조에 있어서,In the normal bicycle 100 structure,

A handle frame 150 having a plate 140 and fixedly connected to an outer circumferential surface of the planetary gear part 120 and covering the front wheel 110 in a “∩” shape, and connected upwardly from a center of the handle frame 150. It is characterized by the configuration consisting of the handle 151.

이하 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은, 첨부한 도면에서 보는 바와 같이 일반적 구성을 갖는 자전거를 개량하여 사용자의 하체 운동은 물론, 상체 운동까지 겸하도록 하여 전신 유산소 운동이 가능한 자전거를 제공하기 위한 것으로서, 자전거(100)의 핸들(151)이 전륜(110)을 중심으로 전후 회동 가능하도록 구성한다.The present invention is to provide a bicycle capable of whole body aerobic exercise by improving the bicycle having a general configuration, as well as the lower body movement of the user, as well as the upper body movement as shown in the accompanying drawings, the handle of the bicycle 100 151 is configured to be able to rotate back and forth around the front wheel (110).

상기 전륜(110)의 축으로 유성기어부(120)가 구비되고, 상기 유성기어부(120) 외측을 커버링하는 원판플레이트(140)를 형성한다.The planetary gear unit 120 is provided as an axis of the front wheel 110, and a disc plate 140 covering the outer side of the planetary gear unit 120 is formed.

상기 유성기어부(120)의 중앙측으로 구성되는 태양기어(121) 중앙으로 일방향으로 운동력을 전달하는 니이들베어링(130)이 축설되고 상기 니이들베어링(130)과 전륜(110)의 축이 연결되도록 한다.The needle bearing 130 for transmitting the kinetic force in one direction to the center of the sun gear 121 composed of the center side of the planetary gear unit 120 is constructed so that the shaft of the needle bearing 130 and the front wheel 110 is connected do.

한편, 상기 태양기어(121)와 치차 결합되도록 그 외주면으로 구비되는 유성기어(122)가 구비되고, 상기 유성기어(122)와 치차 결합되는 세그먼트기어(123)가 구성된다.On the other hand, the planetary gear 122 is provided on the outer peripheral surface so that the gears and the gears are coupled to the sun gear 121, the segment gear 123 is geared to the planetary gear 122 is configured.

상기 세그먼트기어(123) 외주면으로는 핸들프레임(150)이 전륜(110)을 커버하듯이 "∩" 형상을 갖으며 고정되어지고 그 핸들프레임(150) 중앙측으로부터 핸들(151)이 상방향으로 고정되는 구조를 갖는다.As the outer peripheral surface of the segment gear 123, the handle frame 150 is fixed to have a "∩" shape as the front wheel 110 covers, and the handle 151 is upward from the center side of the handle frame 150. It has a fixed structure.

상기한 구성을 갖는 자전거(100)의 구성을 이용하여서 되는 작동관계를 설명하면, 사용자가 자전거(100)에 탑승한 상태에서 페달을 밟아 전진 운동력을 발생시키게 되는데 필요에 따라 전륜(110)을 이용하여 전진 운동력을 발생시킬 수 있다.Referring to the operation relationship by using the configuration of the bicycle 100 having the above configuration, the user generates a forward movement force by stepping on the pedal in the state of riding on the bicycle 100 using the front wheel 110 as necessary To generate forward momentum.

즉, 핸들(151)을 사용자측으로 잡아당기게 되면, 핸들(151)과 연동되는 핸들프레임(150)이 회전되는데 상기 핸들프레임(150)과 유성기어부(120)의 세그먼트기어(123) 외주면이 고정되어 있으므로, 상기 핸들(151)을 사용자측으로 잡아 당기게 되면, 세그먼트기어(123)가 회전되는 상태에 있게 된다.That is, when the handle 151 is pulled toward the user side, the handle frame 150 interlocked with the handle 151 is rotated, and the outer peripheral surface of the segment gear 123 of the handle frame 150 and the planetary gear unit 120 is fixed. Therefore, when the handle 151 is pulled toward the user side, the segment gear 123 is in a state of being rotated.

이와같이 세그먼트기어(123)가 회전되면 내주면측으로 치차결합되어 있는 유성기어(122)가 회전하면서 이와 동시에 다수 유성기어(122)와 치차결합된 태양기어(121)를 회전시키게 되는데, 태양기어(121)축 내부로 일방향으로만 회전력을 전달할 수 있는 니이들베어링(130)에 의해 축(111)이 연동 회전되어 전륜(110)을 전진방향으로 회전시켜 자전거(100)의 전진 운동력을 제공하게 되어, 페달에 의해 제공되는 전진운동력과 함께 전륜(110)측으로도 전진 운동력이 제공되어 자전거(100)의 속력을 가속할 수 있게 된다.When the segment gear 123 is rotated as described above, the planetary gear 122 that is geared to the inner circumferential surface side rotates and simultaneously rotates the sun gear 121 that is geared to the plurality of planetary gears 122 and the sun gear 121. The shaft 111 is interlocked by the needle bearing 130 which can transmit the rotational force only in one direction to the inside of the shaft, thereby rotating the front wheel 110 in the forward direction to provide the forward movement force of the bicycle 100, and the pedals. The forward movement force is also provided to the front wheel 110 along with the forward movement force provided by the to accelerate the speed of the bicycle 100.

한편, 지속적인 핸들(151)의 전후 조작을 위해 핸들(151)을 잡아당긴 상태에서 앞방향으로 핸들(151)을 제치게 되는데, 이때에도 동일하게 세그먼트기어(123) 가 반대방향으로 회전되고 그 세그먼트기어(123) 내주면과 치차결합된 유성기어(122)가 상술한 방향과는 반대방향으로 회전되고, 이와 동시에 태양기어(121) 또한 반대 방향으로 회전되어지는데, 상기 태양기어(121) 중앙측으로 축설되는 일방향으로 운동력을 전달하는 니이들 베어링(130)에 의해 상기 태양기어(121)의 회전력이 니이들 베어링(130)에서 공회전되어 전륜(110)과 연결되는 축(111)으로 그 회전력이 전달되지 못하게 되어, 핸들(151)을 앞방향으로 제어없이 회전시킬 수 있게 된다.On the other hand, the handle 151 is pushed forward in a state in which the handle 151 is pulled for the continuous front and rear operation of the handle 151, and the segment gear 123 is rotated in the opposite direction in the same manner, and the segment The planetary gear 122 geared to the inner circumferential surface of the gear 123 is rotated in the opposite direction to the above-described direction, and at the same time, the sun gear 121 is also rotated in the opposite direction. The rotational force of the sun gear 121 is idle by the needle bearing 130 by the needle bearing 130 which transmits the kinetic force in one direction, and the rotational force is not transmitted to the shaft 111 connected to the front wheel 110. As a result, the handle 151 can be rotated forward without control.

이때, 상기 핸들(151)의 과도한 회동이 발생 되면 탑승자의 안전을 해칠수 있게 되므로, 핸들(151)의 과도한 회동을 방지하기 위해 원판플레이트(140)의 외주면측으로 구비되는 스토퍼(141)와 접하게 되면 더 이상의 회동이 방지되므로, 사용자가 안정된 자세를 유지하면서도 전륜(110)측으로 전진 운동력이 지속적으로 제공되도록 함으로써, 자전거(100)의 전체적 속력 향상은 물론 자전거(100)를 이용하여 하체근력 및 상체근력 강화에 따른 운동성 향상과, 전신 운동 효과를 이룰 수 있게 되는 것이다.In this case, when excessive rotation of the handle 151 is generated, the safety of the occupant may be impaired. When the handle 151 comes into contact with the stopper 141 provided on the outer circumferential surface side of the disc plate 140 to prevent excessive rotation of the handle 151. Since no further rotation is prevented, the user maintains a stable posture so that the forward movement force is continuously provided to the front wheel 110, thereby improving the overall speed of the bicycle 100 as well as lower body strength and upper body strength using the bicycle 100. Enhancement of movement and strengthening of the whole body will be able to achieve the effect.

따라서 본 발명에 의하면, 자전거를 탑승한 상태에서 발을 이용하여 페달을 밟아 전진 구동력을 얻음과 동시에, 팔을 이용하여 핸들을 전후로 회동시키며 전륜을 구동할 수 있도록 하여, 상체 및 하체의 운동이 고르게 이루어질 수 있도록 하는 효과를 기대할 수 있다.Therefore, according to the present invention, while using the bicycle to step on the pedal using the foot to obtain the forward driving force, and by using the arm to rotate the front and rear wheels to drive the front wheel, evenly the upper and lower body movement You can expect the effect to be achieved.
