Description

Technical Field

[0001] The present application relates to the technical field of fitness equipment, and more specifically, to an all-in-one climbing and rowing machine. Background Art

[0002] Dangerous sports like outdoor climbing and rowing are increasingly popular among young people. Climbing can boost confidence and ambition, improve balance and enhance physical fitness and strength by utilizing both hands and feet, foster focus, and increase flexibility and coordination. Rowing, on the other hand, strengthens the muscles of the legs, waist, upper limbs, chest, and back. Rowing is a comprehensive exercise that mobilizes over 80% of the body's muscles, providing a comprehensive workout for the entire body, including the back, arms, shoulders, lower back, thighs, waist, and abdomen.

[0003] To this end, climbing and rowing machines have been developed to simulate rock climbing and rowing movements, respectively, to improve physical fitness, endurance, and perseverance while also strengthening the body's overall coordination. Another advantage of indoor climbing and rowing machines is their low impact on joints, making them suitable for elderly people with underlying health conditions, thus benefiting a wide range of people.

[0004] However, the climbing machines and rowing machines on the market are independent devices and are not compatible with climbing and rowing functions, so they cannot perform both climbing and rowing exercises.

[0005] In view of this, it is urgent to optimize the structure of climbing equipment and rowing equipment with single functions to ensure that the requirements of climbing and rowing exercises can be met while the overall space occupied by the equipment is small. Summary of the Invention

[0020] In some embodiments, guide wheels that slide along guide rails are provided on both sides of the inner walls of the rowing cushion.

[0021] In contrast to the single-function sports equipment on the market, this application proposes a climbing and rowing all-in-one machine. This all-in-one machine integrates climbing and rowing functions into one device. When folded upright, it becomes a climbing exercise device, and when unfolded horizontally, it becomes a rowing exercise device. This device simultaneously transforms two dangerous outdoor sports, climbing and rowing, into indoor sports. Users can choose the sport that suits them best, and it is safe, convenient, and highly reliable. Furthermore, the overall size is comparable to that of individual devices, and it does not take up space. Compared to existing technologies, this application has the following technical advantages:

[0022] First, a base mechanism is configured, which provides overall support for the all-in-one machine. In the folded state, the hook of the main frame mechanism only needs to be pressed into the middle hook hole of the base mechanism under gravity, and the elastic force of the elastic connecting rod assembly can automatically lock it to ensure the climbing exercise needs. When the hook needs to be loosened from the base mechanism for flipping and unfolding, it is only necessary to step on the pedal device with the foot and then lift the hook to disengage the hook from the base mechanism. It can meet at least two fitness needs, including climbing fitness in the folded state and rowing fitness in the unfolded state. The hooking and detaching operation is convenient, the applicability is strong, and the cost is low.

[0023] Secondly, the main frame is equipped with left and right foot pedal assemblies, rowing handles, guide rebound device and fan damping wheel, and the rowing rail mechanism is equipped with a rowing cushion, which can simulate the real rowing scene and achieve the effect of rowing fitness.

[0024] Thirdly, the climbing rail mechanism is equipped with a left climbing footrest, a right climbing footrest, a left handle frame and a right handle frame. The left and right climbing footrests and the left and right handle frames are connected by a pulley transmission assembly to realize the same direction or opposite direction movement, thereby meeting the climbing movement function.

[0025] Finally, the rowing rail mechanism and the climbing rail mechanism are distributed up and down, realizing the two-in-one rowing and climbing functions without increasing the overall space volume, achieving the purpose of miniaturization and lightweight of the equipment, saving placement space, supporting applicability in multiple occasions, and saving design costs and usage costs.

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the climbing and rowing machine provided in this application when it is in the unfolded state; Figure 2 This is a structural diagram of the climbing and rowing machine provided in this application when it is in a folded state.

[0042] The present application provides an all-in-one climbing and rowing machine, which mainly includes a base mechanism 1, a main frame mechanism 2, a rowing guide rail mechanism 3 and a climbing guide rail mechanism 4.

[0043] The base mechanism 1 includes a cross frame and two support frames. The support frames are installed on the cross frame. The cross frame is a shell structure with a hollow installation cavity inside. A fixing plate 102 is installed on the inner wall of the middle position of the installation cavity. A spring hanging column 106 is installed in the installation cavity at the first end of the cross frame. The spring hanging column 106 is vertically downwardly arranged perpendicular to the top wall of the cross frame. A pedal fixing plate 101 is installed on the outer wall of the second end of the cross frame. A mounting hole is opened at the second end of the cross frame, and the mounting hole is arranged on the inner side of the pedal fixing plate 101. The pedal device 104 has a pedal and a hinged plate. The pedal is installed on the hinged plate. The upper part of the hinged plate is hinged to the pedal fixing plate 101 through a hinge. The lower part of the hinged plate is arranged in the installation cavity through the installation hole. The hinged plate is provided with a hinged plate guide groove 1041 below the hinge part. The hinged plate guide groove 1041 is a vertically distributed waist-shaped groove. A rotating sleeve is installed in the hinged plate guide groove 1041. The rotating sleeve can slide in the hinged plate guide groove 1041. Under the connection of the connecting piece, the hinge plate is hinged to one end of the elastic connecting rod assembly, and the pedal can be hinged and swung up and down relative to the U-shaped plate 108 under the action of external pedaling force. The hook plate 103 is attached to the outer side of the fixed plate 102. A hook fixing hole and an inverted oblique hole are formed in the middle of the hook plate 103. The hook fixing hole and the inverted oblique hole are interconnected. The inverted oblique hole is vertically distributed and has a slope. The hook fixing hole is located at the bottom of the inverted oblique hole. The hook fixing hole and the inverted oblique hole form an L-shaped structure to facilitate the entry and removal of the hook 16. A slide groove is provided on each side of the hook fixing hole and the inverted oblique hole. Two sliding assemblies are fixedly mounted on the fixed plate 102. The two sliding assemblies are distributed in the two slide grooves. The two slide grooves are preferably waist-shaped grooves and are distributed horizontally. Under the pull of the elastic connecting rod assembly, the hook plate 103 can slide horizontally relative to the fixed plate 102.

[0044] When the mechanism is reset, the hook 16 is pressed downward by gravity into the oblique hole of the hook plate 103 and snapped into the hook fixing hole, automatically resetting under the action of the elastic connecting rod assembly. When the mechanism is released, the hook 16 is lifted by stepping on the pedal device 104, and the hook 16 is successively released from the hook fixing hole and the oblique hole, thereby disengaging the mechanism, which is convenient to operate. The hook 16 and the fixing plate 102 provided on the connecting rod can achieve the fixation and release of the pedal device 104 at a certain stretch length of the return spring, thereby facilitating the deployment and folding of the climbing device or rowing device.

[0045] Please refer to Figures 3 to 5 , Figure 3 for Figure 1 Schematic diagram of the structure of the middle base mechanism; Figure 4 for Figure 3Exploded diagram; Figure 5 for Figure 3 Schematic diagram of the structure when the middle base mechanism is in a loose state.

[0046] In one specific embodiment, the elastic link assembly includes a pedal link 105, a spring, and a spring link 112. One end of the pedal link 105 is threadedly connected to the side of the hook plate 103, and the other end is mounted on a U-shaped plate 108. The pedal link 105 can be hingedly connected to the pedal device 104 via the U-shaped plate 108 and the connector. The spring is mounted on a spring hanging column 106, and the other end of the spring is connected to the spring link 112. The other end of the spring link 112 is threadedly connected to the other side of the hook plate 103. After assembly, the hook plate 103 is installed from one side and extends through the interior of the cross frame. One end of the spring is installed in the spring hanging hole of the spring link 112, and the other end is hooked 16 in the groove in the middle of the spring hanging column 106 on the cross frame. A locking bolt 109 is passed through the washer 110 and the sliding sleeve 111 through the hook plate guide groove 1031 on the hook plate 103 to secure it to the fixed plate 102 of the cross frame. The sliding sleeve 111 can slide freely within the hook plate guide groove 1031 on the hook plate 103. Preferably, the transition between the hook fixing hole and the inverted inclined hole is rounded to facilitate smooth movement of the hook 16. In addition, the two sliding grooves are symmetrically arranged to ensure symmetrical movement of the pedal link 105 and the spring link 112, and to ensure smoother operation of the pedal hook mechanism as a whole.

[0047] When the device is folded, the main frame mechanism 2 drives the hook 16 through the inverted inclined hole and inserts it into the hook fixing hole. When the spring returns, it pulls the connecting rod, thereby driving the hook plate 103 to lock the hook 16, ultimately connecting the device to the pedal hook mechanism. When the device is unfolded, the device body can be separated from the base mechanism 1 and flipped and folded by stepping on the pedal device 104. This is simple and convenient operation, flexible assembly and disassembly, and does not take up space.

[0048] The main frame mechanism 2 includes a main frame 201 , a fan damping wheel 9 , a hook mounting column with a hook 16 , a rowing handle 13 , a guide rebound device, a left foot pedal assembly 23 and a right foot pedal assembly 24 .

[0049] The main frame 201 can be flipped, folded, or unfolded relative to the base mechanism 1 via two left and right rotating shaft sleeve assemblies. Specifically, the left and right adapter sleeves 10 are fixedly connected to the base mechanism 1 using connectors. The outer wall of the main frame 201 is fixedly mounted with a rotating shaft sleeve, which houses the rotating shaft. The ends of the rotating shaft are mounted in bearings in the left and right adapter sleeves 10. When the main frame 201 is folded, it rotates about the axis of the rotating shaft. The main frame 201 is equipped with a fan shaft 8 that can rotate bidirectionally about the axis. The middle portion is equipped with a sprocket. The fan damper pulley 9 is connected to the fan shaft 8 via bearings and a one-way bearing. Under the action of the one-way bearing, the fan damper pulley 9 can only rotate in one direction relative to the fan shaft 8.

[0050] Furthermore, a left footrest assembly 23 and a right footrest assembly 24 are disposed on the left and right sides of the main frame 2. Specifically, the left footrest assembly 23 comprises a left footrest frame and a left footrest. The left footrest frame is a plate-like structure with a keyed sleeve built into its inner wall. The left footrest is secured to the left footrest frame via a connector. Similarly, the right footrest assembly 24 comprises a right footrest frame and a right footrest. The right footrest frame is a plate-like structure with a keyed sleeve built into its inner wall. The right footrest is secured to the right footrest frame via a connector.

[0051] The main frame is equipped with a rowing handle 13. A hook mounting post with a hook 16 is fixedly mounted on the top of the main frame. The rowing handle 13 is fixedly connected by a chain 7 inside the hook mounting post. The other end of the rowing handle 13 passes over a sprocket inside the hook mounting post and connects to a guide and rebound device inside the hook mounting post. A rowing rail mechanism 3 is fixedly mounted on the rear end of the main frame mechanism 2, and a rowing seat 14 is mounted on it. The user sits on the rowing seat 14 and pulls the rowing handle 13 with both hands to simulate the rowing motion.

[0052] The climbing guide rail mechanism 4 is fixedly installed at the bottom of the main frame mechanism 2 and the rowing guide rail mechanism 3. The guide rail of the climbing guide rail mechanism 4 is equipped with an air avoidance groove and a fixing hole. A slide is provided on each side of the guide rail. A rear bracket 17 is installed on the outer wall of the tail end of the guide rail, and a climbing movable handrail is installed on the outer wall of the middle part of the guide rail. A pulley transmission assembly is provided inside the guide rail. The left climbing footrest 18, the right climbing footrest 19, the left handle frame 20 and the right handle frame 21 are fixedly connected to the pulley transmission assembly. Each climbing footrest and handle frame slides in the slide of the main frame, and the climbing footrest and handle frame on the same side can move in the same direction or in opposite directions in the transmission of the pulley transmission assembly.

[0053] Please refer to Figures 6 to 8 , Figure 6 for Figure 1 Exploded view of the footrest mechanism with adjustable angle; Figure 7 for Figure 6 A schematic diagram of the structure when the left and right footrest assemblies are at the same angle; Figure 8 for Figure 6 A schematic diagram of the structure when the left and right footrest assemblies are in another angular position.

[0054] In a preferred embodiment, the angles of the left and right footrest assemblies are adjustable. The main frame 201 also includes a shift lever assembly, a pressure plate 202, an angle adjustment block 203, and an elastic connecting rod insert assembly. The main frame 201 generally has a rectangular shell structure, with an internal mounting cavity and a plurality of mounting holes defined in its sidewalls. A shift lever assembly shaft 204 extends through the middle of the shift lever assembly. The shift lever assembly can rotate relative to the shift lever assembly shaft 204. An open retaining ring 205 is mounted on the shift lever assembly shaft 204 to facilitate positioning of the shift lever assembly. After assembly, the shift lever assembly shaft 204 is mounted to the main frame 201 using a rotating connector 212. The lower part of the gear lever group is rotatably connected to the first end of the elastic link assembly through a connecting piece, and the second end of the elastic link assembly is connected to the elastic link plug plate assembly. The elastic link plug plate assembly can be selectively inserted into the two positioning grooves 2031 of the angle adjustment block 203 or pulled out from the positioning groove 2031 under the pulling of the gear lever group and the guidance of the pressure plate guide groove 2021.

[0055] The angle adjustment block 203 is mounted in the mounting cavity of the main frame 201. It has two positioning slots 2031. The bottom of the angle adjustment block 203 is fixedly connected to the pedal shaft 215, with the ends of the pedal shaft 215 extending through the side walls of the mounting cavity. Furthermore, fixed sleeves 206 are mounted on the side walls of the main frame 201. The rotating sleeves are mounted on the fixed sleeves 206, and the pedal shaft 215 extends through the rotating sleeves, allowing it to rotate within the sleeves. The angle adjustment block 203 is equipped with fixing holes and positioning slots 2031. Connectors are used to attach the angle adjustment block 203 to the pedal shaft 215 through the fixing holes. Sleeves 207 with built-in keyways are mounted on the inner sidewalls of the left and right pedal assemblies 23 and 24. Keys 208 are used to secure the left and right pedal assemblies 23 and 24 to the pedal shaft 215, with the ends secured by connectors.

[0056] In a specific embodiment, the gear lever group includes a ball handle 209 and a gear lever body 210. The ball handle 209 is inserted into the top of the gear lever body 210 through the insertion rod at its bottom. Open retaining rings 205 are installed on both sides of the gear lever body 210. The bottom of the gear lever body 210 is rotatably connected to the elastic connecting rod assembly through a connecting piece. After the gear lever body 210 is positioned by the open retaining ring 205, it is installed on the main frame 201 using the gear lever shaft and the connecting piece.

[0057] The elastic connecting rod and insert plate assembly includes a connecting rod 211, a rotating connector 212, two springs, and an insert plate 213. One end of the connecting rod 211 is pivotally connected to the shift lever body 210 via the rotating connector 212. The other end of the connecting rod 211 is connected to the insert plate 213. The two springs are respectively installed in two spring slots in the insert plate 213. The other ends of the springs abut against the sliding support plate 214 of the main frame. The insert plate 213 is a rectangular plate with a guide groove. The pressure plate 202 is fixed to the inner wall of the main frame's mounting cavity. The top of the pressure plate has a pressure plate guide groove 2021. A locking member passes through the pressure plate guide groove 2021 and slides into the insert plate 213.

[0058] like Figure 7 and Figure 8 When the pedal angle needs to be adjusted, the shift lever assembly is manually pulled backward. The shift lever assembly, through the connecting rod, disengages the inserting plate 213 from one positioning slot 2031 on the angle adjustment block 203. At this time, the elastic connecting rod assembly is in a compressed state. After adjusting the pedal angle, the shift lever assembly is released. At this time, the inserting plate 213 is retracted under the action of the elastic connecting rod assembly and inserted into the other positioning slot 2031 on the angle adjustment block 203 at the required step angle, achieving anti-rotation positioning.

[0059] The two positioning slots 2031 on the angle adjustment block 203 are preferably, but not limited to, waist-shaped slots. For example, they can also be square slots or adjustment slots with different gears.

[0060] When the ball handle 209 is pulled backward, the middle part of the gear lever body 210 rotates around the gear lever group shaft 204, and the bottom of the gear lever body 210 drives the connecting rod to pull the insert plate 213 out of the positioning groove 2031 of the angle adjustment block 203. At this time, the spring is in a compressed state. After releasing the ball handle 209, the spring returns to push the insert plate 213 into the positioning groove 2031 to stop the angle adjustment block 203 from rotating, so as to fix the angles of the left foot pedal assembly 23 and the right foot pedal assembly 24.

[0061] like Figure 9 and Figure 10 As shown; Figure 9 for Figure 1 Structural diagram of the middle climbing rail mechanism; Figure 10 for Figure 9 Exploded diagram.

[0062] Specifically, the pulley drive assembly includes two synchronous belts 401, four guide pulley frames 402, four pressure blocks 403, an upper synchronous pulley shaft 404, a lower synchronous pulley shaft 405, four square-seated ball bearings 406, two connecting cables 407, and connectors. The pressure blocks 403 and connectors securely connect the ends of the synchronous belts 401 to the two guide pulley frames 402. The assembled guide pulley frames 402 are then slid into the left and right guideways of the guide rails. The upper synchronous pulley shaft 404 is threaded through the upper synchronous belt 401 and secured to the guide rails using two square-seated ball bearings 406 and connectors. Once installed, the upper synchronous pulley shaft 404 can rotate about its axis. Similarly, the two ends of the synchronous belt 401 are connected to the two lower guide wheel frames 402 using a pressure block 403 and a connector. The assembled guide wheel frames 402 are then slid into the left and right guide rails. The lower synchronous wheel shaft 405 is passed through the lower synchronous belt 401 and secured to the guide rail using two square-socket ball bearings 406 and connectors. After installation, the lower synchronous wheel shaft 405 can rotate about its axis. The connecting cable 407 is equipped with connecting terminals at both ends, each with a circular hole. The connecting terminals are passed through the powder sleeve 412 and the circular holes on the connecting cable 407 to connect the guide wheel frames 402. If climbing requires the hand and foot to move in the same direction on one side, the two connecting cables 407 are arranged in parallel, connecting the two guide wheel frames 402 on the same side. If climbing requires the hand and foot to move in opposite directions on one side, the two connecting cables 407 are staggered in space, connecting the guide wheel frames 402 on opposite sides. The flywheel seat 410 and the flywheel 409 are fixedly connected by a connector. The assembled flywheel seat 410 and the flywheel 409 are fixed to the lower synchronous wheel shaft 405 by a tension sleeve 411. The lower synchronous wheel shaft 405 and the flywheel 409 rotate synchronously during movement, and the flywheel 409 can generate rotational inertia damping during movement. The pedals are fixed to the rotating shaft of the pedal frame 408 by a connector, so that the pedals can rotate relative to the pedal frame 408. The two pedal frames 408 are respectively fixed to the guide wheel frames 402 on both sides of the lower portion by connectors. The left handle frame 20 is fixed to the upper left guide wheel frame 402 by a connector, and the right handle frame 21 is fixed to the upper right guide wheel frame 402 by a connector.

[0063] After installation, Figure 10 As shown, the climbing guide rail mechanism 4 allows a user to stand on the left and right climbing footrests, respectively, with both hands grasping the handles on the left handle frame 20 and the right handle frame 21, and move their feet up and down in a staggered manner. If the connecting cable 407 connects the upper and lower guide wheel frames 402 on the same side, the hand and foot on one side move in the same direction; if the connecting cable 407 connects the upper and lower guide wheel frames 402 on different sides, the hand and foot on one side move in opposite directions. Different modes of climbing movements can be achieved by different connection methods of the connecting cable 407. The up and down staggered movement of the feet can drive the flywheel 409 to rotate, and the rotation of the flywheel 409 can generate inertial damping.
