먼저, 본 고안에 따른 헬스자전거(100)의 지지프레임(110)과 손잡이(120)와 계기판(130)과 안장(140)과 페달(150)은 종래기술과 기능상 동일하므로 자세한 설명은 생략하고, 다만 손잡이(120)와 안장(140)의 사이에 정/역구동장치(1)가 장착된 것에 차이점이 포함됨을 첨언한다.First, since the support frame 110 and the handle 120 and the instrument panel 130 and the saddle 140 and the pedal 150 of the fitness bicycle 100 according to the present invention is the same in functionality as the prior art, a detailed description thereof will be omitted. However, the difference between the handle 120 and the saddle 140 is included that the forward / reverse drive device 1 is mounted.
물론, 정/역구동장치(1)는 도 2에서와 같은 헬스자전거의 형상 및 구조에 한정하지는 않고 다양한 형태의 헬스자전거에 적용할 수 있다.Of course, the forward / reverse drive device 1 is not limited to the shape and structure of the health bike as shown in Figure 2 can be applied to a variety of health bikes.
그리고, 회전원판(10)은, 회전기구에 내장되어 덮개를 통해 밀폐되는 원반형상의 회전부재로서, 그 중심부에 회전축(20)을 장착하기 위한 중심축공(11)이 돌출되게 형성되면서, 이 중심축공(11)의 측부에 제1.2피동드럼(40.50)을 각각 장착하기 위한 설치공이 돌출되게 형성된다.The rotating disc 10 is a disc-shaped rotating member which is embedded in a rotating mechanism and sealed through a cover, and the central shaft hole 11 for mounting the rotating shaft 20 protrudes from the central portion thereof. On the side of (11), mounting holes for mounting the 1.2 driven drums 40.50 respectively are formed to protrude.
그리고, 회전축(20)은, 회전원판(10)의 중심축공(11)에 베어링(23)을 통해 설치되어 회전하는 부재로서, 그 회전경로상에 장착된 제1클러치베어링(21)을 통해 일방향으로만 회전원판(10)을 회전시킨다.The rotation shaft 20 is a member installed in the central shaft hole 11 of the rotation disc 10 through the bearing 23 to rotate, and is rotated in one direction through the first clutch bearing 21 mounted on the rotation path. Only rotate the rotating disc 10.
물론, 회전축(20)의 양단부에 페달(150)을 설치하여 정/역구동장치(1)의 정회전 또는 역회전과정에서 이용함은 당연하다.Of course, the pedal 150 is provided at both ends of the rotating shaft 20 to be used in the forward or reverse rotation process of the forward / reverse drive device 1.
그리고, 구동드럼(30)은, 회전축(20)의 상부측에 베어링(34)을 통해 장착되는 원통부재로서, 그 둘레면에 이후에 설명하게 되는 장력조절부재(60)가 감겨지는 권취면(33)이 오목하게 형성되면서, 그 회전경로상에 장착된 제2클러치베어링(31)을 통해 일방향으로만 회전원판(10)을 회전시킨다.In addition, the driving drum 30 is a cylindrical member mounted on the upper side of the rotating shaft 20 through the bearing 34, and the winding surface (W) on which the tension adjusting member 60 to be described later is wound on the circumferential surface thereof ( While the 33 is concave, the rotation disc 10 is rotated in only one direction through the second clutch bearing 31 mounted on the rotation path.
물론, 회전축(20)의 제1클러치베어링(21)과 구동드럼(30)의 제2클러치베어링 (31)은 서로 반대방향으로 작동됨은 당연하다.Of course, the first clutch bearing 21 of the rotating shaft 20 and the second clutch bearing 31 of the driving drum 30 are naturally operated in opposite directions.
그리고, 제1피동드럼(40)은, 회전원판(10)의 설치공에 베어링(44)을 통해 장착되는 원통부재로서, 그 둘레면 상부측에 이후에 설명하게 되는 장력조절부재(60)가 감겨지는 권취면(43)이 형성되면서, 그 둘레면 하부측에 중심축공(11)의 외벽을 따라 면접촉되는 제1접촉면(42)이 형성되어 있다.In addition, the first driven drum 40 is a cylindrical member mounted to the installation hole of the rotating disc 10 through the bearing 44, and the tension adjusting member 60 described later on the upper side of the circumferential surface is provided. While the winding surface 43 to be wound is formed, the first contact surface 42 which is in surface contact along the outer wall of the central shaft hole 11 is formed at the lower side of the peripheral surface thereof.
또한, 제1피동드럼(40)은 그 회전경로상에 장착된 제3클러치베어링(41)을 통해 일방향으로만 작동한다.In addition, the first driven drum 40 operates only in one direction through the third clutch bearing 41 mounted on the rotation path thereof.
그리고, 제2피동드럼(50)은, 제1피동드럼(40)과 대응하는 것으로서, 그 둘레면에 장력조절부재(60)가 감겨지는 권취면(53)과 중심축공(11)의 외벽을 따라 면접촉되는 제2접촉면(52)이 각각 형성되어 있다.The second driven drum 50 corresponds to the first driven drum 40, and the outer wall of the winding surface 53 and the central shaft hole 11 in which the tension adjusting member 60 is wound on the circumferential surface thereof. Accordingly, second contact surfaces 52 which are in surface contact with each other are formed.
또한, 제2피동드럼(50)은 그 회전경로상에 장착된 제4클러치베어링(51)을 통해 일방향으로만 회전한다.In addition, the second driven drum 50 rotates only in one direction through the fourth clutch bearing 51 mounted on the rotation path thereof.
물론, 제1피동드럼(40)의 제3클러치베어링(41)과 제2피동드럼(50)의 제4클러치베어링(51)은 서로 동일한 방향으로 작동한다.Of course, the third clutch bearing 41 of the first driven drum 40 and the fourth clutch bearing 51 of the second driven drum 50 operate in the same direction.
그리고, 장력조절부재(60)는, 드럼(30.40.50)의 권취면(33.43.53)에 감겨지는 것으로서, 제1.2피동드럼(40.50)의 사이에 장착된 텐션베어링(61)을 통해 장력이 조절되며, 벨트 또는 체인 중 어느 하나로 성형함이 바람직하다.The tension adjusting member 60 is wound around the winding surface 33.43.53 of the drum 30.40.50, and the tension is adjusted through the tension bearing 61 mounted between the 1.2 driven drums 40.50. It is preferably controlled and molded into either a belt or a chain.
이하, 본 고안에 따른 작용을 설명하면 다음과 같다,Hereinafter, the operation according to the present invention is as follows,
먼저, 정/역구동장치(1)의 회전축(20)에 장착된 페달(150)을 정방향으로 회전시키면, 회전축(20)의 회전경로에 구비된 제1클러치베어링(21)에 의해 정방향으로 회전원판(10)을 회전시키게 된다.First, when the pedal 150 mounted on the rotation shaft 20 of the forward / reverse drive device 1 is rotated in the forward direction, the pedal 150 rotates in the forward direction by the first clutch bearing 21 provided in the rotation path of the rotation shaft 20. The disk 10 is rotated.
이때, 구동드럼(30)은 제2클러치베어링(31)에 의해 공회전을 반복하는 상태이므로, 구동드럼(30)에 장력조절부재(60)를 매개로하여 연결되어 있던 제1피동드럼(40)과 제2피동드럼(50)이 공회전한다.At this time, since the driving drum 30 is in a state of repeating idling by the second clutch bearing 31, the first driven drum 40 connected to the driving drum 30 via the tension adjusting member 60. And the second driven drum 50 idles.
한편, 회전축(20)의 페달(150)을 역방향으로 회전시키면, 제1클러치베어링 (21)에 의해 회전축(20)의 공회전하며, 구동드럼(30)의 회전경로상에 구비된 제2클러치베어링(31)에 의해 회전원판(10)이 역회전한다.On the other hand, when the pedal 150 of the rotating shaft 20 is rotated in the reverse direction, the first clutch bearing 21 is idling the rotating shaft 20, the second clutch bearing provided on the rotation path of the drive drum (30) The rotation disc 10 reversely rotates by 31.
즉, 구동드럼(30)에 장력조절부재(60)를 매개로 연결된 제1피동드럼(40)과 제2피동드럼(50)이 회전하므로써, 제1.2피동드럼(40.50)의 제1.2접촉면(42.52)에 면접촉되어있던 회전원판(10)이 회전하는 것이다.That is, as the first driven drum 40 and the second driven drum 50 connected to the driving drum 30 via the tension adjusting member 60 rotate, the 1.2 contact surfaces 42.52 of the 1.2 driven drum 40.50 are rotated. Rotating disk 10 was in contact with the surface is rotated.
따라서, 정/역구동장치(1)에서 제1.2.3.4클러치베어링(21.31.41.51)의 상호작용에 의해 회전원판(10)이 정회전 또는 역회전함은 물론, 회전축(20)과 드럼(30. 40.50)이 회전상태 또는 공회전상태를 유지하는 것이다.Therefore, in the forward / reverse drive device 1, the rotating disc 10 rotates forward or reverse by the interaction of the 1.2.3.4 clutch bearings 21.31.41.51, as well as the rotating shaft 20 and the drum 30. 40.50) to maintain the rotation or idling state.
이상에서 설명한 바와 같이 본 고안에 따른 헬스자전거용 회전기구의 정/역구동 장치에 의하면, 정/역구동장치에 내장된 제1.2.3.4클러치베어링의 상호작용에 의해 회전원판이 정회전 또는 역회전하므로써, 헬스자전거용 회전기구의 정회전 및 역회전과정에서 얻을 수 있는 운동효율이 극대화되어 장단지나 종아리 근육 등의 균형적인 발달이 가능해질 뿐만 아니라 정/역회전과정에서 운동에 대한 흠미감이 유발되어 운동효율이 증대되는 효과가 있는 것이다.As described above, according to the forward / reverse drive device of the rotation mechanism for a fitness bicycle according to the present invention, the rotation disc is rotated forward or reverse by interaction of the clutch bearing 1.2.3.4 embedded in the forward / reverse drive device. By maximizing the exercise efficiency that can be obtained in the forward and reverse rotation processes of the fitness bicycle rotating mechanism, not only the balanced development of the short and calf muscles is possible, but also the flaw of movement in the forward / reverse rotation process is caused. It has the effect of increasing the exercise efficiency.
