도 1은 본 발명에 따른 정역구동 헬스 자전거의 전체적인 작동구조를 보인 단면도이다.1 is a cross-sectional view showing the overall operating structure of the forward and backward driving fitness bike according to the present invention.

본 발명에 따른 정역구동 헬스 자전거는 도 1에서 보는 바와 같이 하지부(110), 상지부(150) 및 부하(190)를 포함한다. 이때, 하지부(110)와 상지부(150)에는 하지부(110)와 상지부(150)를 구동시키는 통상의 크랭크와 페달(도시되지 않음)이 구비된다.The forward and backward driving fitness bike according to the present invention includes a lower leg 110, an upper limb 150 and a load 190 as shown in FIG. 1. At this time, the lower limb 110 and the upper limb 150 are provided with a normal crank and a pedal (not shown) for driving the lower limb 110 and the upper limb 150.

도 2는 하지부의 내부구조를 보인 단면도이다.2 is a cross-sectional view showing the internal structure of the lower portion.

하지부(110)는 도 2에서 보는 바와 같이 1차축(111), 2차축(121), 3차축(131)으로 구성된다.As shown in FIG. 2, the lower portion 110 includes a primary shaft 111, a secondary shaft 121, and a tertiary shaft 131.

1차축(111)은 다리운동용 페달(도시되지 않음)에 결합되는 것으로, 발로 구르는 구동축에 해당된다. 이러한 1차축(111)의 양측에는 1차축(111)을 지지하는 하우징(112a,112b) 및 베어링이 장착된다.The primary axle 111 is coupled to the pedal (not shown) for the leg exercise, and corresponds to the driving shaft rolled with the foot. Both sides of the primary shaft 111 are mounted with housings 112a and 112b and bearings supporting the primary shaft 111.

그리고 일측 하우징(112a)의 내측에 인접한 1차축(111)에는 부하(190)로 밸트(Normal Velt, NV)연결되는 출력밸트풀리(113)가 결합된다. 이때, 출력밸트풀리(113)는 일방향클러치베어링(CB)이 내장되어 1차축(111)이 정회전할때에 구속되어 부하(190)로 연결되고, 1차축(111)이 역회전할때에는 구속되지 않게 된다.In addition, an output belt pulley 113 coupled to a belt (Normal Velt, NV) is coupled to the primary shaft 111 adjacent to the inner side of the one housing 112a. At this time, the output belt pulley 113 has a one-way clutch bearing (CB) built in and is constrained when the primary shaft 111 rotates forward, and is connected to the load 190, and is not constrained when the primary shaft 111 reverses rotation. do.

At this time, the primary shaft transfer belt pulley 117 is extended longer and coupled with the output belt pulley 113. That is, the other side of the output belt pulley 113 is further extended is formed integrally with the extension portion 114 is coupled to the other side of the primary shaft transfer belt pulley 117, the primary shaft transfer belt pulley 117 and the extension portion ( Between the 114 one-way clutch bearing (CB) is built. Therefore, the output belt pulley 113 is constrained when the primary shaft transfer belt pulley 117 is rotated forward, and the output belt pulley 113 is not constrained when the primary shaft transfer belt pulley 117 is reversely rotated.

여기에서, 1차축전달밸트풀리(117)에는 상지부(150)의 구동력을 입력받는 외부입력풀리(180)가 형성된다.Here, an external input pulley 180 that receives the driving force of the upper limb 150 is formed in the primary shaft transfer belt pulley 117.

다음으로 2차축(121)은 1차축(111)의 하측에 배치되고, 3차축(131)은 다시 2차축(121)의 하측에 배치된다. 이러한 2차축(121) 및 3차축(131)은 하나의 하우징(122)으로 지지되며, 하우징(122)과 각 축(121,131)의 사이에는 베어링이 내장된다. 그리고 2차축(121) 및 3차축(131)에는 1차축역전밸트풀리(116)의 하측방향으로 2차축역전전달밸트풀리(123) 및 3차축풀리(133)가 장착된다. 이때, 2차축역전전달밸트풀리(123)는 1차축전달밸트풀리(117)의 하측까지 더 연장된다.Next, the secondary shaft 121 is disposed below the primary shaft 111, and the tertiary shaft 131 is disposed below the secondary shaft 121 again. The secondary shaft 121 and the tertiary shaft 131 are supported by one housing 122, and a bearing is embedded between the housing 122 and each of the shafts 121 and 131. In addition, the secondary axle 121 and the third axle 131 are equipped with a secondary axle reverse transfer belt pulley 123 and a third axle pulley 133 in a downward direction of the primary axle reverse belt pulley 116. At this time, the secondary shaft reverse transmission belt pulley 123 is further extended to the lower side of the primary shaft transmission belt pulley 117.

도 3은 도 2의 측면도로 하지부 더블밸트 걸림을 보인 요부 도면이다.Figure 3 is a side view of the main part showing a double belt hook in the side view of FIG.

하지부(110)에는 두개의 밸트가 체결되는데,The lower part 110 is fastened to two belts,

첫 번째 밸트는 더블밸트(Double Velt, DV)로 도 3에서 보는 바와 같이 1차축역전밸트풀리(116)와 2차축역전전달밸트풀리(123)와 3차축풀리(133)가 연결된다. 이때, 1차축역전밸트풀리(116)와 3차축풀리(133)는 더블밸트(DV)에 내접되게 체결되고, 2차축역전전달밸트풀리(123)는 더블밸트(DV)에 외접되게 체결된다.The first belt is a double belt (Double Velt, DV) as shown in Figure 3 is connected to the primary axis reversing belt pulley 116, the secondary axis reversing transmission belt pulley 123 and the third axle pulley 133. At this time, the primary shaft reversing belt pulley 116 and the tertiary shaft pulley 133 are fastened internally to the double belt DV, and the secondary shaft reversing belt pulley 123 is fastened externally to the double belt DV.

도 4는 상지부의 내부구조를 보인 단면도이다.Figure 4 is a cross-sectional view showing the internal structure of the upper limbs.

상지부(150)는 도 4에서 보는 바와 같이 1차축(151) 및 2차축(161)으로 구성된다.The upper limb 150 is composed of a primary shaft 151 and a secondary shaft 161 as shown in FIG.

1차축(151)은 팔운동용 페달(도시되지 않음)에 결합되는 것으로, 팔로 구르는 구동축에 해당된다. 이러한 1차축(151)의 양측에는 1차축(151)을 지지하는 하우징(152a,152b) 및 베어링이 장착된다.The primary shaft 151 is coupled to the arm exercise pedal (not shown), and corresponds to the driving shaft rolled by the arm. Both sides of the primary shaft 151 are mounted with housings 152a and 152b supporting the primary shaft 151 and bearings.

그리고 1차축(151)에는 1차축밸트풀리(153)와 1차축기어(156)가 결합된다. 이때, 1차축밸트풀리(153)에는 일방향클러치베어링(CB)이 내장된다. 따라서 1차축(151)이 정회전시에는 일방향클러치베어링(CB)에 의해 구속되어 1차축밸트풀리(153)가 정회전되고, 1차축(151)이 역회전시에는 구속되지 않는다. 또한, 1차축밸트풀리(153)에는 하지부(110)에 형성되는 외부입력풀리(180)의 상부측까지 더 연장되는 상지밸트출력풀리(154)가 형성되고, 상지밸트출력풀리(154)와 외부입력풀리(180)는 일반밸트(NV)로 체결되어 부하(190)와 연결된다.In addition, the primary shaft belt pulley 153 and the primary shaft gear 156 are coupled to the primary shaft 151. At this time, the one-way clutch bearing (CB) is built in the primary shaft belt pulley (153). Therefore, when the primary shaft 151 is rotated forward, the primary shaft belt pulley 153 is forwardly restrained by the one-way clutch bearing CB, and the primary shaft 151 is not restrained when the reverse rotation. In addition, the upper shaft belt pulley 153 is formed with an upper belt output pulley 154 further extending to the upper side of the external input pulley 180 formed in the lower portion 110, the upper belt output pulley 154 and The external input pulley 180 is connected to the load 190 is fastened by a general belt (NV).

따라서, 1차축(151)이 정회전하면, 1차축밸트풀리(153)가 구속되면서 1차축밸트풀리(153) 및 상지밸트출력풀리(154)가 정회전되고, 이에 따라 하지부(110)의 외부입력풀리(180) 및 출력밸트풀리(113)가 정회전되면서 부하(190)를 구동시킨다.Therefore, when the primary shaft 151 rotates forward, the primary shaft belt pulley 153 is constrained and the primary shaft belt pulley 153 and the upper belt output pulley 154 rotate forward, and thus, the lower portion of the lower portion 110. The external input pulley 180 and the output belt pulley 113 are rotated forward to drive the load 190.

또는, 1차축(151)이 역회전하면, 1차축기어(156)가 역회전되면서 2차축기어(166) 및 2차축(161)을 정회전시키고, 2차축(161)에 2차축밸트풀리(163)가 구속되면서 다시 1차축밸트풀리(153)를 정회전시키면서 1차축(151)의 정회전시와 동일하게 작동된다.Alternatively, when the primary shaft 151 reversely rotates, the primary shaft gear 156 reversely rotates to rotate the secondary shaft gear 166 and the secondary shaft 161 forward, and the secondary shaft belt pulley (2) on the secondary shaft 161. While the 163 is restrained and rotates the primary shaft belt pulley 153 forward again, the same operation as the forward rotation of the primary axle 151 is performed.
