The flywheel 61 is a one-way wheel that is rotatably disposed in the accommodating space 215 of the main seat 21 and has an axis 611. The drive plate 62 is coupled to a second drive plate 53 of one of the transmission units 5. The driving belt 63 has an annular shape and is sleeved on the axial center 611 of the flywheel 61 and the outer periphery of the driving plate 62. The resistance adjusting mechanism 64 is provided to the main seat 21 corresponding to the flywheel 61 for adjusting the resistance when the flywheel 61 rotates. It is worth mentioning that the flywheel 61 can also be replaced with other equivalent items, such as a fan wheel, and the resistance unit 6 can be additionally connected to a power generating device (not shown) to transmit through the flywheel 61. Move to generate electricity. The foregoing power generating device is well known and will not be described herein.

The recovery units 7 are respectively connected to the transmission units 5 and respectively provide a restoring force to the rowing units 4. Each of the return units 7 includes a two-phase spaced fixed pulley 71 and a tension rope 72. The fixed pulleys 71 are rotatably disposed on one side of the front frame 211 of the main seat 21. One end of the tension cord 72 is fixed to the main seat 21, and is wound around the fixed pulley 71, and the other end is connected to the take-up reel 532 of the second transmission disc 53.

When the user pulls the paddle 42 to drive the guiding rod 41 to move along its own axis L1, the first strip 52 is pulled, thereby driving the first driving disc 51 to rotate, and simultaneously passing the second strip. The belt 54 pulls the second drive plate 53, which will begin to wind the tension rope 72 and drive the drive plate 62 to rotate to drive the flywheel 61 to rotate. When the user relaxes the paddle 42 , the tension cord 72 provides a restoring force to the second drive plate 53 and passes through the second strip 54 , the first drive plate 51 and the first strip in succession. 52, the restoring force is guided to the guiding rod 41, causing the paddle rod 42 to return to the original position and placed forward (see FIG. 4).

The structure of each element of the present embodiment and the relationship between them have been described above, and the actual operation will be further described below.

Referring to Figures 4, 5 and 6, a user (not shown) sits on the seat 3 and holds the grip area 423 of the paddles 42 with both hands. In the initial state, the grip area 423 of the paddles 42 is positioned above the front frame 211 and placed forward. When the paddles 42 are pulled backwards, due to the arrangement direction of the guiding rods 41 and the pivoting angle thereof with the paddles 42, the grip area 423 of the paddles 42 gradually tilts toward Move inside, so that the user can simulate the way of applying force when actually paddling. When the user pulls the paddles 42 backwards until they are unable to pull, they reach the position shown by the solid lines in FIGS. 5 and 6.

When the user pulls the paddles 42 , the transmission unit 5 transmits the resistance generated by the resistance unit 6 to the paddles 42 , so that the paddles can be simulated when the boat is rubbed by the water body during rowing. resistance.

Referring to Figures 4 and 7, when the user wants to return the position of the paddles 42, the hand grips 423 can be turned outward (as shown in Figure 7) and moved forward until the paddles are moved. The grip area 423 of 42 is placed forward (as shown in FIG. 4). This simulates the reset motion during actual paddle. At this time, since the tension ropes 72 additionally provide a restoring force, the user can return to the home position more quickly, and then the operation of pulling the paddles 42 is re-executed. In this way, the user can effectively exercise the muscle force by repeatedly performing the operation of pulling and resetting.

Through the above description, the advantages of this new model can be summarized as follows:

1. The extending direction of the guiding rods 41 defines the swinging manner of the paddles 42. When the user pulls the paddles 42, the user moves in an obliquely inward and upward direction, and the manner of swinging is close to the actual one. The paddle action is used to effectively use the muscle strength of the chest and back to improve the muscle strength training effect.

2. The guiding rods 41 effectively limit the trajectory of the movement of the paddles 42. Therefore, when the operator pulls the paddles 42, the paddles 42 move along a fixed trajectory, so that the force dispersion can be avoided. Improve the training effect of muscle strength.

3. The links 222 allow the paddles 42 to be yawed thereon, thereby allowing the paddles 42 to be respectively rotated about the axis L1 of the guide bars 41, thereby allowing the paddles 42 to be rotated. It can simulate the action of resetting when paddle.

4. The radius of the take-up spool 511 of the first drive disc 51 is smaller than the take-up reel 512. Therefore, if the moment of pulling the take-up spool 511 is equal to the moment of pulling the take-up reel 512, it is necessary to apply Greater power. In this arrangement, the resistance unit only needs to provide a slight resistance, and the operator needs to apply a force exceeding the resistance to push the paddles 42. Thus, the load range can be expanded to meet the needs of the high-intensity exerciser.

In summary, the arrangement of the guide rods 41 limits the manner in which the paddles 42 are swung, thereby simulating the actual paddle action, thereby improving the muscle strength training effect. Therefore, it is indeed possible to achieve the purpose of the present invention.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
