[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] like Figures 1 to 4 As shown in the illustration, a rowing machine 100 according to an embodiment of this application includes: a frame 10, a pedal mechanism 20, a seat mechanism 30, and a handle mechanism 40. Furthermore, the rowing machine 100 also includes a resistance source 60. The resistance source 60 is connected to both the pedal mechanism 20 and the handle mechanism 40 to output resistance to them, satisfying the exerciser's purpose of working their arms and legs.

[0047] The frame 10 has a track 11 at its front end; a pedal mechanism 20 is movably mounted on the track 11; a seat cushion mechanism 30 is connected to the rear end of the frame 10; and a handle mechanism 40 is connected to the frame 10.

[0048] The resistance source 60 is arranged at the front end of the frame 10, and the moving path of the pedal mechanism 20 at least partially passes through the resistance source. In this way, the moving path of the pedal mechanism 20 fully utilizes the length space occupied by the resistance source 60, thereby facilitating the reduction of the overall length of the rowing machine 100.

[0049] In summary, the implementation of the technical scheme of the embodiment has the following beneficial effects: the rowing machine 100 of the above scheme is used in the case of training of a trainer, when in use, the trainer sits on the seat cushion mechanism 30, the feet are stepped on the pedal mechanism 20, and the hands are firmly held on the pulling handle mechanism 40. At the same time, the hands are pulled backward and recovered forward, and the feet are pedaled or retracted, so that the pedal mechanism 20 can move forward and backward on the frame 10, thereby realizing rowing training. Compared with the existing rowing machine 100, the pedal mechanism 20 is designed to move forward and backward on the track 11 of the frame 10, which can fully utilize the space at the front end of the frame 10 for leg pedaling, and the seat cushion mechanism 30 remains relatively static with the frame 10, thereby greatly reducing the overall length of the rowing machine 100, reducing the space requirement for use, and having a wider application range.

[0050] Please continue to refer to Figure 6 In some embodiments, the track 11 is provided with a track groove 111, the pedal mechanism 20 includes a pedal shaft 21, a roller 22, and a pedal assembly 23, the pedal assembly 23 is installed at both ends of the pedal shaft 21, and the roller 22 is installed at the middle of the pedal shaft 21 and is rollably arranged in the track groove 111. During training, the trainer pedals the pedal assembly 23 with the feet, the pedaling force is transmitted to the pedal shaft 21, and then the roller 22 is driven to roll in the track groove 111, thereby realizing smooth movement of the pedal mechanism 20 on the track 11. In this process, the pedal assembly 23 can perform strength training on the feet of the trainer under the power provided by the resistance source 60.

[0051] Please continue to refer to Figure 7 and Figure 8 In the above embodiment, the pedal assembly 23 includes a foot pedal 231, a rotating shaft 232, and a pedal pin 233, the foot pedal 231 is rotatably sleeved on the outside of the rotating shaft 232, the rotating shaft 232 is provided with a containing hole 232a, the pedal pin 233 is slidably inserted into the containing hole 232a, and a clamping column 233a formed at the end of the pedal pin 233 can extend out of the containing hole 232a or retract into the containing hole 232a. The end of the pedal shaft 21 is provided with a limiting hole 211, and the clamping column 233a formed at the end of the pedal pin 233 can be inserted into the limiting hole 211, so that the pedal assembly 23 is fixed with the pedal shaft 21.

[0052] The foot pedal 231 can rotate clockwise and counterclockwise in a vertical plane parallel to the length direction side of the frame 10 to achieve angle adjustment, so as to meet different leg lengths and leg posture changes in pedaling actions. The pedal pin 233 extends from the containing hole 232a and makes the clamping column 233a inserted into the limiting hole 211, so as to connect and fix the foot pedal 231 with the pedal shaft 21. Thus, the pedal assembly 23 is driven to move synchronously by the pedal shaft 21 and the roller 22 along the track 11 to realize training of both feet of the trainer.

[0053] In other embodiments, a limiting assembly can also be added between the rotating shaft 232 and the foot pedal 231, so that the foot pedal 231 can be fixed at a certain angle according to the needs of the trainer. Specifically, the limiting assembly can be installed on the foot pedal 231 or the rotating shaft 232.

[0054] On the basis of the above embodiments, the pedal assembly 23 further comprises a handle 234 and an elastic member 235. The hole wall of the containing hole 232a is formed with a step 2321a, the elastic member 235 abuts between the step 2321a and the pedal pin 233, the pedal pin 233 extends out of the rotating shaft 232 at an end away from the clamping column 233a and is connected with the handle 234, and the handle 234 is limited and abuts with the foot pedal 231. The elastic member 235 provides elastic force for the pedal pin 233 to move towards the pedal shaft 21, so as to press the pedal pin 233 towards the pedal shaft 21 and ensure that the clamping column 233a is stably inserted into the limiting hole 211 and is not easy to be loosened. For example, the elastic member 235 can be but is not limited to a spring.

[0055] In yet other embodiments, the pedal assembly 23 further comprises a mounting seat 236 and a pedal positioning member 237. The mounting seat 236 is provided with a mounting hole 236a and an avoiding cavity 236b in communication. The avoiding cavity 236b is a semi-closed open chamber. The pedal positioning member 237 is arranged on the pedal shaft 21 and is inserted into the mounting hole 236a, and the avoiding cavity 236b is used for avoiding the end of the pedal shaft 21, so that when the clamping column 233a formed at the end of the pedal pin 233 is separated from the limiting hole 211 at the end of the pedal shaft 21, the pedal assembly 23 can be folded downward relative to the pedal shaft 21 with the pedal positioning member 237 as the rotating center.

[0056] When it is needed to release the fixed connection relationship between the pedal assembly 23 and the pedal shaft 21 and to rotate and fold the pedal assembly 23, the handle 234 is pulled backward to drive the pedal pin 233 to retreat and compress the elastic member 235, so that the clamping column 233a can be pulled out of the limiting hole 211. Then, the foot pedal 231 is pressed downward, so that the foot pedal 231 can be rotated downward to close to the frame 10 with the pedal positioning member 237 as the rotating center, and the folding operation is completed. Thus, the overall width of the rowing machine 100 can be greatly reduced, and the occupied space can be reduced.

[0057] In addition, after the folding is completed, the handle 234 is released, the pedal pin 233 is in contact with the pedal shaft 21 in the circumferential direction under the action of the elastic member 235, so that the foot pedal 231 cannot be easily shaken, and the reliability of the storage is guaranteed.

[0058] Please continue to refer to Figure 5 The track 11 is formed on the upper surface of the frame 10, so as to facilitate the installation and removal of the pedal mechanism 20. However, in order to prevent the pedal mechanism 20 from being skewed and falling off from the frame 10 due to uneven force during use, in some embodiments, the frame 10 further comprises a limiting cover plate 50, which is arranged above the track 11. The limiting cover plate 50 can effectively constrain the upward movement of the pedal mechanism 20 from the track 11, so as to prevent the roller 22 from falling out of the track 11. In addition, the limiting cover plate 50 can also hide the roller 22 and the pedal shaft 21, thereby improving the appearance of the rowing machine 100.

[0059] Optionally, the installation mode of the limiting cover plate 50 can be, but is not limited to, any one of screwing, buckle connection, magnetic attraction connection and the like.

[0060] Please continue to refer to Figure 4 In addition, on the basis of any of the above embodiments, the limiting cover plate 50 is provided with a first guide wheel 51. The frame 10 is further provided with a second guide wheel 52, a third guide wheel 53, a fourth guide wheel 54 and a fifth guide wheel 55 at intervals. The pulling handle mechanism 40 comprises a sixth guide wheel 56, and the resistance source 60 leads out a first pulling rope 61 and a second pulling rope 62. The first pulling rope 61 is connected to the pulling handle mechanism 40 after passing through the second guide wheel 52, the third guide wheel 53 and the first guide wheel 51 in sequence. The second pulling rope 62 is connected to the fixed hole on the pedal shaft 21 after passing through the fourth guide wheel 54, the fifth guide wheel 55 and the sixth guide wheel 56 in sequence.

[0061] Thus, the first pulling rope 61 can provide resistance to the pulling handle mechanism 40 to meet the training needs of the trainer's hands. At the same time, the second pulling rope 62 can provide resistance to the pedal mechanism 20 to meet the training needs of the trainer's legs. It can be understood that the resistance source 60 is used to provide resistance in the opposite direction of the trainer's hands and feet. During the rowing training of the trainer, the first pulling rope 61 and the second pulling rope 62 are constantly moving back and forth. At this time, the first guide wheel 51, the second guide wheel 52, the third guide wheel 53, the fourth guide wheel 54, the fifth guide wheel 55 and the sixth guide wheel 56 play a guiding and limiting role for the first pulling rope 61 and the second pulling rope 62, so as to ensure the smooth movement of the first pulling rope 61 and the second pulling rope 62. In use, the trainer can pull the pulling handle mechanism 40 with both hands, and at the same time, stomp the pedal mechanism 20 with both feet to realize the training of rowing action; or only pull the pulling handle mechanism 40, without stumping the pedal mechanism 20 with both feet, or only stomp the pedal mechanism 20 with both legs, without pulling the pulling handle mechanism 40 with both hands, to independently realize the training of upper limbs or lower limbs. The rowing machine of the present application can provide more diverse training modes for the trainer.

[0062] The resistance source 60 adopts a motor or other power equipment with equivalent technical effects. The resistance source 60 can be one, and the power is equally divided into two paths through a differential mechanism to transmit to the first pull rope 61 and the second pull rope 62. Alternatively, the resistance source 60 can be two, respectively connected with the first pull rope 61 and the second pull rope 62, and independently output the same resistance in two paths.

[0063] Please continue to refer to Figures 1 to 5 In still other embodiments, the pull handle mechanism 40 includes a pull handle base 41, a pull handle support 42, and a pull handle assembly 43, the sixth guide pulley 56 is arranged on the pull handle base 41, the pull handle support 42 is rotatably arranged on the pull handle base 41, the pull handle support 42 can be rotated to fold close to the rack 10 or unfolded away from the rack 10, and the pull handle assembly 43 is arranged on the pull handle support 42 and connected with the second pull rope 62. The pull handle base 41 installs and supports the pull handle support 42 and the pull handle assembly 43, in the use state, the pull handle support 42 is unfolded upward and in the vertical posture with the pull handle base 41, so as to support the pull handle assembly 43 to a height position suitable for the operator to operate with both hands. When in the non-use state, the pull handle support 42 is rotated downward relative to the pull handle base 41 until it abuts against the upper surface of the rack 10, so as to complete the folding and reduce the height of the rowing machine 100 and the floor space occupied by the machine.

[0064] Specifically, in the above-mentioned embodiments, the pull handle mechanism 40 further includes a connecting pin 44 and a positioning pin 45, the pull handle base 41 is rotatably connected with the pull handle support 42 through the connecting pin 44, and the positioning pin 45 can be arranged on the pull handle base 41 and the pull handle support 42 to fix the pull handle support 42 with the pull handle base 41, or the positioning pin 45 can be separated from the pull handle base 41 and the pull handle support 42 to enable the pull handle support 42 to rotate and fold relative to the pull handle base 41. Thus, the positioning pin 45 provides the freedom degree required for the pull handle support 42 to rotate relative to the pull handle base 41, so as to flexibly switch between the unfolded and folded states by rotation. The positioning pin 45 can reliably fix the pull handle support 42 with the pull handle base 41 when the pull handle support 42 is unfolded, and further reliably support the action of the pull handle assembly 43.

[0065] It can be understood that the pull handle support 42 and the pull handle base 41 are provided with a pair of connecting holes arranged in position, and the connecting pin 44 is inserted into the two connecting holes for fixation. The pull handle support 42 and the pull handle base 41 are provided with a pair of positioning holes arranged in position, the positioning holes and the connecting holes are vertically spaced, the positioning pin 45 is inserted into the two positioning holes, and the unfolded pull handle support 42 and the pull handle base 41 are fixed, or the positioning pin 45 is extracted from the two positioning holes, and the locking of the pull handle support 42 is released, so that the pull handle support 42 can rotate and fold relative to the pull handle base 41.

[0066] In some embodiments, the handle support 42 is provided with two limiting wheels arranged at intervals at one end away from the handle seat 41, the handle assembly 43 comprises a limiting block 431 and a handle 432 connected together, the second pull rope 62 passes through the gap between the two limiting wheels and is connected with the limiting block 431, and the limiting block 431 abuts against the two limiting wheels. The rotation of the two limiting wheels can guide and limit the extension and contraction movement of the first pull rope 61, and reduce the friction and wear of the first pull rope 61 to improve the service life. The gap between the two limiting wheels is smaller than the size of the limiting block 431, and the limiting block 431 is limited by the limiting wheels to prevent the first pull rope 61 from retracting to the resistance source 60. The handle 432 can be a ring-shaped rod or a single rod structure, which is suitable for being held by a trainer with one hand or both hands.

[0067] Please continue to refer to Figure 1 and Figure 3 In still some embodiments, the seat mechanism 30 comprises a seat longitudinal pipe 31, the frame 10 comprises a frame longitudinal pipe 12 and a fixing member 13, the front end of the seat longitudinal pipe 31 is provided with at least two adjusting holes 311 arranged at intervals along the length direction thereof, the frame longitudinal pipe 12 is provided with a fixing hole, and the seat longitudinal pipe 31 is slidably inserted into the frame longitudinal pipe 12, and the fixing member 13 can be inserted into the fixing hole and any adjusting hole 311. The seat longitudinal pipe 31 is slidably extended and contracted in the frame longitudinal pipe 12, so that the length of the rowing machine 100, i.e. the distance between the seat mechanism 30 and the handle mechanism 40 and the pedal mechanism 20, can be flexibly adjusted to meet the use requirements of trainers with different heights and arm lengths. It can be understood that, after the length is adjusted, the fixing member 13 is inserted into the fixing hole and the currently aligned adjusting hole 311, so that the seat mechanism 30 and the frame 10 can be kept relatively fixed.

[0068] Further, the rear end of the seat longitudinal pipe 31 is also provided with a receiving hole 312, and the fixing member 13 can be inserted into the fixing hole and the receiving hole 312 when the seat longitudinal pipe 31 is completely retracted into the frame longitudinal pipe 12. In the non-use condition, the seat longitudinal pipe 31 is completely retracted into the frame longitudinal pipe 12, so that the overall length of the rowing machine 100 is minimized, and the rowing machine 100 is facilitated to be carried, stored and moved, and the space occupation is reduced.

[0069] Optionally, the fixing member 13 can be any one of a bolt, a knob and the like, which can be selected according to actual requirements.

[0070] Please continue to refer to Figure 1 Still further, in order to facilitate the movement of the seat mechanism 30 when the length of the rowing machine 100 is adjusted or the rowing machine 100 is stored and moved, the seat mechanism 30 further comprises a seat transverse pipe 32 connected with the seat longitudinal pipe 31, and first moving wheels 33 are respectively installed at the two ends of the seat transverse pipe 32.
