Description

Technical Field

[0001] This invention relates to the field of sports training equipment technology, specifically to rowing training equipment. Background Technology

[0002] Rowing is a highly challenging water sport that demands a high level of teamwork from its athletes. Currently, rowing training methods generally fall into two categories: one is static training using rowing machines and free-swinging; the other is on-site training in lakes, rivers, and other bodies of water. Coaches observe each athlete's performance and the overall team coordination in both methods, providing guidance to team members to improve team synergy and performance.

[0003] However, both methods have their own problems: the first method cannot simulate the actual rowing scenario for athletes. For example, there is a difference between the force exerted by athletes in the air swing and the force exerted in the actual rowing process. This makes it difficult for coaches to intuitively judge the problems that athletes may have in the actual rowing process based solely on their movements during static training. The second method can intuitively reflect the problems that athletes have in the actual rowing process, but because athletes move in the water during training, coaches cannot provide close guidance on the technical movements of each athlete, and thus cannot effectively improve the athletes' performance. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a rowing training device that can simulate the actual rowing scenario for athletes, allowing coaches to clearly observe the athletes' technical movements in a real rowing environment, thereby facilitating effective coaching.

[0005] A rowing training apparatus according to a first aspect of the present invention includes: support; The hull is configured to float on the water, the hull is used for athletes to ride on, and has a length direction; A movable component is slidably connected to the support in a vertical direction; the hull is connected to the movable component so that the hull can float vertically and swing about the first axis in the water; the first axis is parallel to the length direction of the hull.

[0006] The rowing training device according to embodiments of the present invention has at least the following beneficial effects: Because the support frame is fixed in position, the boat hull, connected to it via movable components, cannot move horizontally across the water. This allows coaches to closely observe the athletes' movements while seated in the boat, enabling them to analyze these movements and provide appropriate guidance. The movable components slide vertically to the support frame, allowing the boat hull to move vertically relative to the support. The boat's buoyancy allows it to float on the water's surface, adapting to changes in water level during the dry and wet seasons. It also simulates the bobbing and sinking conditions of a rowing boat during practice sessions.

[0007] The hull of this invention, through its connection with movable components, can rotate relative to the support about an axis parallel to its own length. This further simulates the rolling motion that may occur during actual rowing. When training in this hull, athletes need to apply the leveling techniques required in actual rowing scenarios to maintain balance. Athletes can thus produce performances closer to those of actual rowing, reducing the difference between training and real rowing habits, improving adaptability to actual rowing, and allowing coaches to observe athletes' more realistic rowing performance and provide more appropriate suggestions for real rowing scenarios.

[0008] During group training, multiple athletes can sit sequentially along the length of the boat. When training together on the boat of this invention, multiple athletes can more closely mimic actual rowing movements, improving teamwork and reducing the likelihood of accidents such as paddle separation or misalignment during competition. Athletes can also provide each other with practical rowing suggestions based on their movements while using the device. Coaches can also observe the athletes' collective performance, which more closely resembles actual rowing, and offer more realistic suggestions, thus improving the overall teamwork of the rowing team.

[0025] In the description of this invention, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] Please refer to Figures 1 to 10 As shown, the present invention proposes a rowing training device for training in water 10, including a support 100, a hull 200 and a movable component 300.

[0027] The hull 200 of the present invention is configured to float on water 10 and is used for athletes to ride on. When the hull 200 of the present invention is placed in water 10, it can simulate an environment in which the hull 200 floats and sinks for the athletes riding on it.

[0028] Please refer to Figure 1 As shown, the movable component 300 of the present invention is slidably connected to the support 100 in the vertical direction, and the movable component 300 can slide relative to the support 100 in the vertical direction when subjected to force. The hull 200 is connected to the movable component 300 so that the hull 200 can float in the water 10 in the vertical direction and swing about a first axis; the first axis is parallel to the length direction of the hull 200.

[0029] With the above scheme, the position of the support 100 is fixed. After the boat 200 is connected to the support 100 via the movable component 300, it cannot move horizontally along the water surface. This allows the coach to observe the movements of the athletes riding in the boat 200 up close, and thus analyze the athletes' movements and provide corresponding guidance. The movable component 300 is slidably connected to the support 100 in the vertical direction, allowing the boat 200 to move vertically relative to the support 100. The boat 200 can float on the water surface under the buoyancy of the water area 10, adapting to the changes in water level during the dry and wet seasons. It can also simulate the sinking and floating conditions of the boat 200 in actual rowing when athletes are practicing in the boat 200.

[0030] During rowing, a rowing boat may roll around an axis parallel to its length due to insufficient skill from the athlete. The hull 200 of this invention, connected to the movable component 300, can rotate relative to the support 100 around an axis parallel to its length, further simulating the rolling motion that may occur during actual rowing. When training in the hull 200, athletes need to apply the leveling techniques required in actual rowing scenarios to maintain balance. This allows athletes to receive training closer to that of actual rowing, reducing the difference in movements between training and actual rowing, improving adaptability to actual rowing, and enabling coaches to observe athletes' performance more closely and provide more relevant advice for real-world rowing situations.

[0031] During group training, multiple athletes can sit sequentially along the length of the hull 200. When multiple athletes train together on the hull 200 of this invention, they can more closely mimic actual rowing performance, improving teamwork and reducing the likelihood of accidents such as paddle separation or misalignment during competition. Athletes can also provide each other with practical rowing suggestions based on their movements while training with the device. Coaches can also observe the athletes' collective performance, which more closely resembles actual rowing, and offer more realistic suggestions, thus improving the overall teamwork of the rowing team.

[0032] refer to Figure 1 , Figure 2 As shown, in some embodiments, the movable component 300 includes a first connector 310 and a second connector 320, and the support 100 includes a first column 110 and a second column 120 spaced apart. The first connector 310 is slidably connected to the first column 110 in the vertical direction, and the second connector 320 is slidably connected to the second column 120 in the vertical direction. The first connector 310 and the second connector 320 are respectively rotatably connected to the two ends of the hull 200 in the length direction around a first axis. With the above scheme, since the two connectors are slidably connected to the first column 110 and the second column 120 in the vertical direction, the hull 200 connected to the first connector 310 and the second connector 320 can also slide in the vertical direction, thereby enabling it to float vertically in the water area 10. Since the two ends of the hull 200 in the length direction are respectively rotatably connected to the first connector 310 and the second connector 320, and both the first connector 310 and the second connector 320 are rotatably connected to the hull 200 around the first axis, the hull 200 can swing around the first axis.

[0033] As a preferred option, please refer to Figure 1As shown, in some embodiments, the first column 110 has a first groove 111, and the second column 120 has a second groove 121. Both the first groove 111 and the second groove 121 extend vertically. At least a portion of the first connector 310 is slidably connected to the first groove 111 in the vertical direction, and at least a portion of the second connector 320 is slidably connected to the second groove 121 in the vertical direction. Through this scheme, the first connector 310 can slide vertically by slidingly connecting to the first groove 111, and the second connector 320 can slide vertically by slidingly connecting to the second groove 121, thereby allowing the hull 200 to slide vertically. It should be noted that workers can also directly lift the hull 200 upwards, causing the connectors to slide upwards out of the grooves of the support 100, thus separating the hull 200 from the support 100. Maintenance personnel can move the vessel 200 meters to land to carry out maintenance and repair work, avoiding interference from the water area 10 during the testing process, which helps to improve testing efficiency.

[0034] In some embodiments, the first connector 310 includes a first pulley that is engaged in a first groove 111, and the second connector 320 includes a second pulley that is engaged in a second groove 121. The pulley slides up and down within the slide rail as the water level of the water area 10 rises and falls, adapting to changes in water level during the dry and wet seasons.

[0035] As a preferred option, please refer to Figure 3 , Figure 4 As shown, where Figure 3 The diagram shows a side view of the hull 200 in some embodiments. In some embodiments, both the first column 110 and the second column 120 extend vertically. The first connector 310 has a first through hole 311, and the second connector 320 has a second through hole 321, both extending vertically. The first column 110 passes through the first through hole 311, allowing the first connector 310 to slide vertically connected to the first column 110. The second column 120 passes through the second through hole 321, allowing the second connector 320 to slide vertically connected to the second column 120. Through this design, the two connectors are fitted onto different columns via through holes, enabling the hull 200 to slide vertically.

[0036] On the other hand, the connection between the connector and the column effectively reduces the possibility of debris such as aquatic plants, algae, and silt entering the through-hole in the water area 10 and causing malfunction. It should be noted that workers can also directly lift the hull 200 upwards, causing the connector to slide out of the through-hole in the bracket 100, thus separating the hull 200 from the bracket 100. After training, the user can disassemble the hull 200 and store it properly. Maintenance personnel can move the hull 200 to land for maintenance and repair work, avoiding interference from the water area 10 during the testing process and improving testing efficiency.

[0037] In some embodiments, the first connector 310 includes a first pulley, which is capable of rolling relative to the inner wall of the first through hole 311 to move vertically, and the second connector 320 includes a second pulley, which is capable of rolling relative to the inner wall of the second through hole 321 to move vertically. The pulleys slide up and down within the through hole according to the rise and fall of the water level in the water area 10, adapting to changes in water level height during the dry and wet seasons.

[0038] For the form in which the hull 200 is connected to the movable component 300, please refer to [reference needed]. Figures 5 to 8 As shown, where Figure 8 The hull 200 is omitted. In some embodiments, the movable component 300 includes a third slider 330, a fourth slider 340, a third connector 350, and a fourth connector (not shown in the figure). The support 100 includes a first column 110 and a second column 120 spaced apart. The third slider 330 is slidably connected to the first column 110 in the vertical direction, and the fourth slider 340 is slidably connected to the second column 120 in the vertical direction. The third connector 350 and the fourth connector respectively support the two ends of the hull 200 in the length direction. The third connector 350 is rotatably connected to the third slider 330 about a first axis, and the fourth connector is rotatably connected to the fourth slider 340 about a first axis. With the above scheme, since the two sliders are slidably connected to the first column 110 and the second column 120 in the vertical direction respectively, the hull 200, whose two ends are connected to the sliders by connectors, can also slide in the vertical direction, thereby enabling it to float vertically in the water area 10. Since the two connecting parts are rotatably connected to the slider, the hull 200 can swing around the first axis.

[0039] It should be noted that the present invention does not limit the rotational connection between the third connector 350 and the third slider 330, or the rotational connection between the fourth connector and the fourth slider. Taking the rotational connection between the third connector 350 and the third slider 330 as an example, in some embodiments, the third slider 330 has an arcuate groove, the third connector 350 has a cylindrical surface, and the third slider 330 has a circular groove, with the cylindrical surface of the third connector 350 slidably connected to the circular groove of the third slider 330. Further, as a preferred embodiment, ball bearings are provided between the cylindrical surface of the third connector 350 and the circular groove of the third slider 330. This solution can further reduce friction during the relative sliding process between the third connector 350 and the third slider 330.

[0040] As a preferred option, please refer to Figures 5 to 8 As shown, in some embodiments, the hull 200 includes a cabin 210, a first end 220, and a second end 230. The cabin 210 is for athletes to ride in, and the first end 220 and the second end 230 are located at opposite ends of the cabin 210 along its length. The first end 220 is detachably connected to a third connector 350, and the second end 230 is detachably connected to a fourth connector. With this design, after training, the user can disassemble the hull 200 separately for storage. When the hull 200 requires maintenance, staff can separate the two ends of the hull 200 along its length from different connectors, thereby moving the hull 200 to land for inspection, avoiding interference from the water area 10 during the maintenance process, and improving the maintenance efficiency of the hull 200.

[0041] On the other hand, when the two ends of the hull 200 are separated from different connectors along its length, the hull 200 can be used directly in actual rowing competitions or activities. When the two ends of the hull 200 are connected to different connectors along its length, the hull 200 can be used for training in the water area 10 without requiring modification. This provides athletes with a riding experience closer to that of an actual rowing boat, and is convenient to use with no modification costs.

[0042] Further, please refer to Figure 6 , Figure 7 , Figure 8As shown, in some embodiments, the third connector 350 has an upwardly opening third mounting groove 351, with at least a portion of the first end 220 received within the third mounting groove 351; the fourth connector has an upwardly opening fourth mounting groove (not shown), with at least a portion of the second end 230 received within the fourth mounting groove; the third mounting groove 351 has opposing first sidewalls 3511 and second sidewalls 3512 in a first direction, both the first sidewalls 3511 and the second sidewalls 3512 abutting against a portion of the first end 220 facing away from the second end 230. On the side, the fourth assembly slot has a third sidewall and a fourth sidewall opposite each other in the first direction. The third sidewall and the fourth sidewall both abut against the side of the second end 230 facing away from the first end 220. The first direction, the length direction of the hull 200 and the vertical direction are perpendicular to each other. The distance between the first sidewall 3511 and the second sidewall 3512 in the first direction gradually decreases from the second end 230 toward the first end 220. The distance between the third sidewall and the fourth sidewall in the first direction gradually decreases from the first end 220 toward the second end 230.

[0043] Since at least a portion of the first end 220 is accommodated within the third assembly groove 351, and at least a portion of the second end 230 is accommodated within the fourth assembly groove, the first sidewall 3511 and the second sidewall 3512 of the third assembly groove 351 can restrict the movement of the first end 220 by abutting against it, and the third and fourth sidewalls of the fourth assembly groove can restrict the movement of the second end 230 by abutting against it. Specifically, regarding the restriction of the movement direction of the ends by the assembly grooves, the distance between the first sidewall 3511 and the second sidewall 3512 in the first direction gradually decreases along the direction from the second end 230 toward the first end 220, and the movement of the first end 220 away from the second end 230 is restricted by the abutting against the first sidewall 3511 and the second sidewall 3512; the distance between the third and fourth sidewalls in the first direction gradually decreases along the direction from the first end 220 toward the second end 230, and the movement of the second end 230 away from the first end 220 is restricted by the abutting against the third and fourth sidewalls. Through the combined action of the first sidewall 3511, the second sidewall 3512, the third sidewall, and the fourth sidewall, the horizontal movement of the hull 200 as a whole is restricted by the third and fourth assembly slots. Furthermore, since both the third and fourth assembly slots open upwards, the user can easily separate the hull 200 from the movable component 300 by simply lifting it upwards, making disassembly more convenient. When assembling the rowing training device of the above embodiment, the user can also directly place the first end 220 of the hull 200 downwards into the third assembly slot 351, and simultaneously place the second end 230 downwards into the fourth assembly slot to complete the installation of the hull 200, making the installation process even more convenient.

[0044] Furthermore, in some embodiments, the movable component 300 further includes a third buffer and a fourth buffer. The third buffer is disposed in the third mounting groove 351 and attached to the first sidewall 3511 and the second sidewall 3512. The first sidewall 3511 and the second sidewall 3512 abut against the side of the first end 220 facing away from the second end 230 via the third buffer. The fourth buffer is disposed in the fourth mounting groove and attached to the third sidewall and the fourth sidewall. The third sidewall and the fourth sidewall abut against the side of the second end 230 facing away from the first end 220 via the fourth buffer. Both the third and fourth buffers are made of rubber. Through this design, the two ends of the hull 200 can be protected by the third and fourth buffers during installation into the mounting groove, reducing the possibility of the hull 200 being damaged by impacts.

[0045] As a preferred embodiment, please refer to Figures 1 to 8 As shown, in some embodiments, the support 100 includes a first column 110, a second column 120, and a base 130. The lower ends of both the first column 110 and the second column 120 are connected to the base 130, which is placed within the water area 10. Through this design, the base 130 fixes the position of the columns, thereby restricting the position of the movable components 300 and the hull 200. Furthermore, since both the first column 110 and the second column 120 are connected to the base 130, the base 130 can fix the relative position between the first column 110 and the second column 120, thus ensuring the parallel relationship between the first column 110 and the second column 120 when the rowing training device is set up in the water area 10, and improving the vertical stability of the hull 200.

[0046] As another preferred embodiment, please refer to Figure 9 , Figure 10 As shown, where Figure 10 (The hull 200 is not shown.) In some embodiments, the support 100 can be fixed to the ground 20 at the boundary of the water area 10. The movable component 300 includes a first arm 370 and a second arm 380. One end of each of the first arm 370 and the second arm 380 is slidably connected to the support 100 in a vertical direction. The other ends of the first arm 370 and the second arm 380 are suspended and rotatably connected to both ends of the hull 200 along its length about a first axis. This solution allows workers to set up the rowing training device on the ground 20, thereby simplifying the installation process and improving installation efficiency. When the water depth of some parts of the water area 10 is too deep, or the riverbed is not conducive to the fixation of the base and construction in the water area 10, the above solution can achieve the fixation of the support 100.

[0047] As a preferred embodiment of the support structure 100, please refer to Figure 9As shown, both the first arm 370 and the second arm 380 are three-pronged support arms. This design can more stably fix the hull 200 and reduce the swaying of the hull 200 along its length.

[0048] The hull 200 of the present invention is configured to float on the water surface 10. Those skilled in the art can achieve the effect of the hull 200 floating on the water surface 10 by using common technical means in the art, based on the actual conditions of the water surface 10 and the materials used for the movable components 300. Exemplarily, in some embodiments, the hull 200 and the movable components 300 can float on the water surface of the water surface 10 due to the buoyancy they receive.

[0049] As a preferred option, please refer to Figure 8 As shown, in some embodiments, the rowing training device further includes a float 400, which is located below and connected to the movable component 300. The float 400 has a density less than that of water. Through this design, the float 400 can use its own buoyancy to propel the movable component 300 and the hull 200 upwards, thereby achieving the effect of the hull 200 floating on the water surface 10.

[0050] Without departing from the inventive concept of this invention, those skilled in the art can choose the rotational connection method between the movable component 300 and the hull 200, thereby enabling the hull 200 to rotate about a first axis. In some embodiments, the movable component 300 includes a bearing, and the hull 200 is connected to other parts of the movable component 300 via the bearing. The bearing is detachable, and the hull 200 can be separated from the movable component 300 by removing the bearing. Further, in some embodiments, a force gauge is provided on the bearing on the front side of the hull 200, and the force gauge is used to record the force curve of the hull 200. The coach can evaluate the athlete's force exertion and coordination through the force curve of the hull 200. In some embodiments, the movable component 300 includes a connector, the connector includes a rotating shaft, the hull 200 is provided with a rotating hole, and the hull 200 and the connector are rotatably connected through a clearance fit between the rotating shaft and the rotating hole.

[0051] Based on the rotational connection between the hull 200 and the movable component 300, in some embodiments, the rowing training device also includes a damper, which is disposed at the rotational connection between the movable component 300 and the hull 200. The inventors have discovered in practice that rowing boats possess a certain degree of self-balancing ability at high speeds and are less prone to capsizing compared to a stationary state. The damper in the above embodiments can assist the hull 200 in returning to its correct position, which is beneficial for further simulating the swaying pattern of the hull 200 in motion and enhancing the athlete's adaptability. On the other hand, the rowing training device equipped with a damper also benefits those who have never rowed before, making it less likely for passengers to lose balance and fall into the water 10 during the experience.

[0052] In some embodiments, the rowing training device further includes an angle limiting member disposed at the rotational connection between the movable component 300 and the hull 200, for limiting the swing angle of the hull 200 relative to the movable component 300. This allows the hull to swing within a set angle range, reducing the probability of passengers falling into the water from the hull 200 due to excessive hull swing amplitude.

[0053] refer to Figures 1 to 10 As shown, in some embodiments, the rowing training device further includes a fixing member 500, and the movable component 300 includes a movable member. The movable member is slidably connected to the support 100 in the vertical direction, and the hull 200 is rotatably connected to the movable member. The fixing member 500 is detachably connected to the movable member and the support 100, so that the movable member can be slidably connected to the support 100 in the vertical direction, or the movable member can be fixed to the support 100. When using the rowing training device of the above embodiments, athletes can first remove the fixing member 500 so that the hull 200 floats directly on the water surface 10, and then use the fixing member 500 to fix the vertical position of the hull 200 relative to the water surface 10. The above solution, through the fixing member 500, can fix the hull 200 and the support 100 relatively in the vertical direction, so that the hull 200 can further simulate the small-amplitude buoyancy of the hull 200 relative to the water surface 10 during rowing. On the other hand, the installation of the fixing element 500, the fixing bracket 100, and the hull 200 also facilitates the experience for those unfamiliar with rowing, making it less likely for passengers to lose their balance and fall into the water 10 during the experience. It should be understood that the movable parts in this embodiment can be the first connecting element 310, the second connecting element 320, the third connecting element 350, or the fourth connecting element mentioned above, or they can be the third slider 330 and the fourth slider. (See reference...) Figure 1 , Figure 2 As shown, the movable parts are the first connecting member 310 and the second connecting member 320. The first connecting member 310 is detachably connected to the first column 110 via the fixing member 500, and the second connecting member 320 is detachably connected to the second column 120 via the fixing member 500. (Reference) Figure 6 , Figure 7 , Figure 8 As shown, the movable parts are the third slider 330 and the fourth slider. The third slider 330 is detachably connected to the first column 110 through the fixing member 500, and the fourth slider is detachably connected to the second column 120 through the fixing member 500.

[0054] This invention does not limit the structural form of the fastener 500; the fastener 500 can be a pin, an expansion block, etc. For example, please refer to... Figure 1 , Figure 2As shown, in some embodiments, the fixing member 500 is a pin. The fixing member 500 is inserted horizontally into the first connector 111 and the first column 110, and abuts against the first connector 111 and the first column 110 in the vertical direction, thereby restricting the relative movement between the first connector 111 and the first column 110 in the vertical direction, and the hull 200 is relatively fixed relative to the support in the vertical direction. Please refer to... Figure 6 , Figure 7 , Figure 8 As shown, in some embodiments, the fixing member 500 is an expansion block. The fixing member 500 expands in the horizontal direction and abuts against the third slider 330 and the first column 110, restricting the relative movement between the third slider 330 and the first column 110 in the vertical direction. The hull 200 is relatively fixed relative to the support 100 in the vertical direction.
