The side-return mechanism 13 includes a hollow housing 131 provided on the bearing side of the transmission wheel 122, and a set A scroll spring 132 in the hollow casing 131. The center end of the scroll spring 131 is a shaft 4 connected to the transmission wheel 122. The M256216 bearing 'is connected at the end to the hollow casing 131. The resistance wheel 121 is a magnetic control wheel, which has the specific effect of generating resistance to resist rotation by the attraction of magnetic force. When the grip 116 is pulled, one end of the pull rope 125 can be pulled out from the coiled state. And drive the transmission wheel 122 and the resistance wheel 121 to rotate, so that the scroll spring 132 is rolled up by the bearing of the transmission wheel 122 that is rotated, and when the user relaxes the grip 116, the transmission wheel 122 can pass the The accumulated elastic force of the scroll spring 132 reverses the original state to the original state, and allows the drawstring 125 that was stretched in the previous action to be rolled back. “So” By using the above-mentioned constituent members and repeated operations, it is possible to use Lu The person has a rowing-like movement effect. However, the volute spring 132 in the return force mechanism 13 is a vortex-shaped steel element whose elastic range is the entire fully retracted and scaled-up size when unrolled, but the steel material is harder and less stretched. Characteristics, so when the user pulls out the grip 116 momentarily, it is very easy to cause the scroll spring 132 to break, or when the grip 116 is to be pulled out to release, it is also very easy because of the scroll spring The instantaneous elastic force of 132 is too large, and the recovery speed is too fast, so that the grip 116 is quickly pulled back to the original state, and it collides with the book 11 of the bracket body, causing damage. [New content] Therefore, the purpose of the new model is to provide a rowing exercise machine that can relax the speed and return to its original state, and is quite cost-effective and not easily damaged. Therefore, the new rowing exercise machine includes a long rod, a mounting seat, a seat, a driving mechanism, and a return force mechanism M256216 that cooperates with the driving mechanism.

The returning force mechanism includes a fixing element provided on the long rod, and a flexible rope having one end fixed to the fixing element and the other end extending and fixed to the transmission wheel. [Embodiment] 15. The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings. Referring to Figures 3, 4, and 5 ', the first preferred embodiment of the novel rowing exercise machine includes-a long rod 2,-a front support swing 3,-a rear field plate 4, a mounting seat 5,-a chair 6, —The driving mechanism 7, a returning force mechanism 8 matched with the driving mechanism 7, and two foot pedals 9. The long rod 2 includes opposite-front end portions 21 and-rear end portions 22. The front pedestal pole 3 is a -cross bar, and is fixedly connected to an end surface of the front end ^ of the long pole 2. The rear support plate 4 is a plate body extending obliquely upward, and is fixed to the rear end portion 22 of the long rod 2. The long 椁 2 θ / reverse 2 延伸 extends obliquely upward from the front end portion 21 toward the rear end portion 20 M256216 22. The mounting base 5 is erected on the long pole 2 near the front support pole 3, and includes a first branch 5 10 15 wood 51 extending upward from one side of the long pole 2 and a The first bracket 51 is correspondingly disposed on the other side of the long rod 2, a first bracket 52, a connecting frame 53 connected to the top P of the first and second brackets 51, 52, and a detachable first bracket 51. A grip bar 54 is provided on the top of the connecting frame 53. ^ The first and second brackets 51 and 52 respectively have a front side 54 away from the seat 6, a rear side 55 opposite to the front side 54, and two each have a perforation and protrude from the front and rear. The elder brothers on the sides 54, 55. The seat 6 is slidably disposed on the long pole 2 and is located between the mounting seat 5 and the rear crotch portion 22. The footboards 9 are respectively pivoted to the left and right sides of the long rod 2, and are located between the seat 6 and the mounting seat 5. The driving mechanism 7 includes a resistance wheel 71, a transmission wheel 72, a guide wheel 73, a transmission belt 74, and a drawstring 75. The resistance wheel 71 is a magnetron wheel, which is pivotally connected between the pivoting members% of the front side 54 of the first and second brackets 52 and 52, and has the specific effect of generating resistance to resist rotation by magnetic attraction. . Refer to FIG. 6 for reference. The transmission wheel 72 is pivotally connected between the coupling members% 55 on the rear side 55 of the first and second brackets 5 and 52. The first and second brackets are arranged at intervals from each other and are annularly concave-first Wheel groove 721,-second wheel groove 722 ', and-third wheel groove 723. The driving belt 74 is held in the first wheel groove ⑶. One end of the drawstring 75 is wound around the second wheel groove 722, and the other end is extended around the guide wheel M provided on the connecting frame 53 and then 20 M256216 is fixed to the grip 54 . 5 10 15 and relying on FIG. 7 'the returning force mechanism 8 includes-provided on the long rod 2,' with a fixing element 81 on the side 55 behind 4 brackets 51, 52, and a side element 2 arranged side by side with the fixing element 81 on the long rod 2 The first pulley on the first and second ends is fixed on the fixing element 81 and the other end is fixed to the fixed element 81 and the other end is arranged on the δHai Changbao 2 and #near the brackets Μ, the ^ th wheel of the front side 54. After bypassing the wheel 83, the first pulley 82 is bypassed and the flexible rope M is fixed to the second wheel groove 723 of the transmission wheel M. In this embodiment, the fixing 2 81 is a metal bundle tube, and one end of the flexible rope 84 is clamped. With reference to FIG. 8 ', the operating mechanism of the rowing exercise machine is as follows. When the user holds the grip 54 and applies a pulling force F, the pulling rope 75 wound around the driving wheel ^ will extend in the direction of the pulling force F of the user. And cause the transmission wheel ^ to be driven. At this time, the transmission wheel 72 will use the transmission belt 74 to link the resistance wheel 71 to rotate in the same direction, so that resistance is applied during the rotation, and at the same time in the same direction The flexible rope 84 is wound, and the strength at the time of recovery of the eight-stretched M is accumulated by one end of the winding, and because the pull rope μ has a fairly good = extension property, and bypasses the first pulley 82 and the second The pulley has a sufficiently extended length after the magic, so it will not break due to sudden pull, and it has a gentler recovery effect than the metal elastic element. With reference to FIG. 9, when the user has pulled the pull rope to a proper length and wants to release the grip lever 54, the flexible rope 84 will make the transmission wheel with its own recovery elasticity in the rolled state. 72 makes reverse rotation, and simultaneously pulls the pull rope 75 in the opposite direction. At this time, since the flexible rope 84 bypasses the first 20 M256216 and the second pulley 82, 83, the overall length increases, so the reply The force also produces a cushioning effect, so that the grip lever 54 and the mounting seat $ can be prevented from colliding quickly, reducing the chance of damage. To sum up, the new rowing exercise machine uses the extensional characteristics of the flexible rope 84 to be supplemented by the buffer structure formed by the first and second pulleys 82 and 83, so that the return force of the return mechanism 8 is comparable. Ease, it is not easy to break when stretched, so it is quite durable. The dish can achieve the main purpose of this new type of rowing. Fitness machine. However, the above are only the preferred embodiments of the new model. When not in this way, the scope of the implementation of the new model is limited, that is, the simple equivalent changes made according to the scope of the patent application of the new model and the content of the new specification. Modifications should still fall within the scope of this new patent.
