Description

Technical Field

[0001] This application relates to the field of fitness equipment technology, and in particular to a flexible, foldable rowing machine. Background Technology

[0002] A rowing machine, also known as a rowing machine, rowing machine, rowing device, ergometer, rowing machine, land rowing machine, or indoor rowing machine, is a machine designed for training purposes and used to simulate rowing on water.

[0003] Currently, water resistance rowing machines include a base frame, a water tank, a guide rail, a seat, a foot support surface, a rope, and a rope winding mechanism. The water tank is fixed to the support frame, and a rotating shaft perpendicular to the ground and a rotating paddle connected to the shaft are pivotally connected inside the water tank. The guide rail is set on the base frame and extends towards one side of the base frame. The seat slides on the guide rail. The foot support surface is set on the base frame and located between the water tank and the guide rail. The rope winding mechanism includes a winding disc, which is set on the shaft and can rotate synchronously with it. The rope is wound on the winding disc, and a handle is connected to the outer end of the rope. An elastic reset structure is provided between the winding disc and the base frame to reset the winding disc.

[0004] Rowing machines are effective in strengthening the muscles of the legs, waist, upper limbs, chest, and back. Users sit on the seat, place their feet on the foot pedals, and push off backward while simultaneously pulling the handles behind them. With legs straight and lower back arched, the arms move backward to the sides, simulating rowing. As the seat moves a certain distance, the legs contract, and the seat slides down the rails, repeating this motion for a complete workout. Each stroke involves a full contraction and extension of the upper limbs, lower limbs, waist, abdomen, and back, providing a full-body aerobic exercise. Furthermore, users can select different resistance levels on the control panel to achieve a more personalized workout.

[0005] Regarding the aforementioned technologies, traditional rowing machines mostly use linear slide rails, with the seat sliding and connected to the linear slide rails. However, the materials used to make the slide rails are generally tubular, aluminum, wood, etc., which have the problems of being inconvenient to fold or being too bulky and space-consuming after folding and storage. Therefore, improvements are needed. Utility Model Content

[0006] To facilitate the folding of the slide rails and reduce the space occupied by the rowing machine when storing it, this application provides a rowing machine that can be bent and folded around the body.

[0007] The rowing device that can be bent and folded around the body provided in this application adopts the following technical solution:

[0008] A flexible, foldable rowing machine includes a rowing machine body, a modular track, and a seat. One end of the modular track is rotatably connected to the rowing machine body. The modular track is composed of several track joints, and the joints are connected by bearings or universal joints, allowing adjacent track joints to bend relative to each other. The surface of the modular track has two parallel arc-shaped grooves. The bottom of the seat is rotatably connected to several rollers, which slide within the two arc-shaped grooves.

[0009] By adopting the above technical solution, and using segmented modular metal tracks, the joints of adjacent tracks are connected by bearings or universal joints, ensuring smooth bending and folding between the two track joints. A universal joint is a mechanical transmission component mainly used to connect different shaft systems (two shafts whose axes do not coincide or have relative movement) and to achieve stable power transmission.

[0010] The modular track can be laid flat to function as a normal sliding rail. The track has curved grooves for the rollers on the seat cushion to slide on. The rollers and the curved grooves work together to ensure the seat cushion doesn't easily deviate during sliding. When not in use, the track joints can be folded, bent, and rolled up, greatly saving space and making it suitable for various scenarios, solving the problem of limited space.

[0011] Preferably, it also includes two foot supports, which are symmetrically arranged and located on both sides of the rowing machine body. The foot supports are used to support the user's feet. The rowing machine body is connected to a handle, which is located between the two foot supports and is used for the user's hands to grip.

[0012] By adopting the above technical solution, the exerciser can sit on the cushion, place both feet on the two foot supports, and push backward. At the same time, they can hold the handles with both hands, pull their legs back, straighten their backs, and swing their arms to the sides, simulating rowing. When the cushion moves a certain distance, the legs contract, and the cushion slides down along the modular track. This process is repeated to achieve the exercise effect.

[0013] Preferably, the foot support seat has several protrusions on its support surface, and an anti-slip ring is connected to the foot support seat to prevent the user's feet from leaving the foot support seat.

[0014] By adopting the above technical solution, the protrusion can increase the static friction between the exerciser's feet and the foot support seat, thus playing a role in preventing slippage; at the same time, the anti-slip ring can limit the movement of the feet, allowing the feet to exert force better, so that the exerciser's feet will not slip off the foot support seat during exercise, improving safety and ensuring the exercise effect.

[0015] Preferably, the roller is detachably connected to the seat cushion, and the outer surface of the roller is covered with a rubber sleeve.

[0016] By adopting the above technical solution, the material of the rubber sleeve can be, but is not limited to, natural rubber, silicone rubber, or polyurethane. The surface of the rubber sleeve typically has a textured design, which increases the friction between the rollers and the contact surface (the curved grooves of the track), preventing slippage and ensuring stable movement of the seat. In addition, the elasticity of rubber materials absorbs vibrations, reducing noise when the rollers roll. It also prevents metal rollers from directly contacting the modular track, preventing scratches and protecting the contact surface. The rollers are consumable parts; when a roller is damaged, it can be replaced individually without replacing the entire seat, thus reducing maintenance costs.

[0017] Preferably, it further includes a fastening bolt, a fastening nut, and a limiting cylinder. The roller is sleeved on the fastening bolt, the limiting cylinder is hollow and is also sleeved on the fastening bolt, a mounting plate is connected to the cushion, one end of the fastening bolt passes through the mounting plate and is screwed to the fastening nut, and the limiting cylinder is located between the mounting plate and the roller.

[0018] By adopting the above technical solution, during installation, the roller and the limiting sleeve are first fitted onto the fastening bolt. Then, one end of the fastening bolt passes through the mounting plate and engages with the fastening nut, relying on the bolt force to secure the bolt. The position of the roller corresponds to the position of the arc-shaped slide groove. When the seat cushion moves, the roller can rotate around the fastening bolt as its axis. During rotation, the roller is restricted by the limiting sleeve, preventing lateral displacement on the fastening bolt and ensuring the relative position of the roller and the arc-shaped slide groove.

[0019] Preferably, one end of the track joint is integrally formed with a protrusion, and the other end is provided with a groove, with the protrusion of the track joint connected to the groove of the adjacent track joint.

[0020] Preferably, it also includes a T-shaped shaft, a positioning cylinder, and a pin. The modular track is detachably connected to the rowing machine body. The bottom of the rowing machine body is symmetrically provided with base plates. A protrusion at one end of the modular track is located between the two base plates. There are two positioning cylinders, which are located on both sides of the protrusion. One end of the T-shaped shaft passes through the base plate, the positioning cylinder, and the protrusion. The pin is inserted into the other end of the T-shaped shaft and is used to prevent the T-shaped shaft from detaching from the base plate.

[0021] By adopting the above technical solution, during installation, the protrusion at one end of the modular track is first placed between the two base plates, and two positioning cylinders are placed on both sides of the protrusion. Next, one end of the T-shaped shaft passes through one base plate, the two positioning cylinders, and the protrusion simultaneously, then exits through the other base plate. Finally, a pin is inserted into the end of the T-shaped shaft to prevent it from detaching from the base plate. The protrusion can rotate around the T-shaped shaft as a pivot point without interfering with the folding and bending of the entire modular track.

[0022] Preferably, it also includes support pads, which are located at the bottom of the rowing machine body and are symmetrically distributed in two. The two support pads are used to make contact with the ground and are made of anti-slip material.

[0023] By adopting the above technical solution, the rowing machine body will also experience a corresponding reaction force during exercise. By adding support pads, the contact area and static friction between the entire rowing machine body and the ground are increased, thereby improving the stability of the rowing machine and ensuring normal exercise for the user.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] (1) By setting up modular tracks, which consist of several track joints, the connection between two adjacent track joints is made by bearings or universal joints, ensuring smooth bending and folding between the two track joints. When the track is not in use, each track joint can be folded, bent and rolled up, which greatly saves space.

[0026] (2) By detachably mounting the rollers on the seat cushion, the rollers are consumable parts. When the rollers are damaged, they can be replaced separately without replacing the entire seat cushion, thus reducing maintenance costs.

[0027] (3) By setting support pads, the support pads can increase the contact area and static friction between the rowing machine body and the ground, play a role in preventing slipping, and improve the stability of the rowing machine. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0038] This application discloses a flexible, foldable rowing device. (See also...) Figures 1 to 3The rowing machine includes a main body 1, a modular track 2, and a seat 3. The main body 1 is placed on the ground, and one end of the modular track 2 is rotatably connected to the main body 1. The modular track 2 consists of several identical track joints 20, which are connected by bearings or universal joints, allowing adjacent track joints 20 to bend relative to each other under stress. One end of each track joint 20 has an integrally formed protrusion 4, and the other end has a groove 5. The protrusion 4 of the track joint 20 is rotatably connected to the groove 5 of the adjacent track joint 20. When the modular track 2 is laid flat on the ground, two parallel arc-shaped grooves 17 are formed on the surface of the modular track 2. Several rollers 6 are rotatably connected to the bottom of the seat 3, and each roller 6 slides within the two arc-shaped grooves 17, allowing the seat 3 to move linearly towards or away from the main body 1.

[0039] Specifically, the rowing machine body 1 is symmetrically equipped with two foot support seats 7, which are used to support the exerciser's feet. A handle 18 is also connected to the rowing machine body 1, located between the two foot support seats 7. The handle 18 is connected to the rope winding mechanism of the rowing machine body 1, allowing the exerciser to grip the handle 18 with both hands. Several protrusions 8 are fixedly connected to the support surface of the foot support seats 7. These protrusions 8 increase the static friction between the exerciser's feet and the foot support seats 7, providing an anti-slip function. Anti-detachment rings 9 are fixedly connected to the foot support seats 7, preventing the exerciser's feet from slipping off the foot support seats 7 and improving exercise safety.

[0040] The exerciser can sit on the cushion 3, place both feet on the two foot support seats 7, and push off backward. At the same time, they can hold onto the handles 18 and pull their legs back, straightening their backs and arching their backs, while swinging their arms to the sides and back, simulating rowing. When the cushion 3 moves a certain distance, the legs contract, and the cushion 3 slides down along the modular track 2. This process is repeated to achieve the desired exercise effect.

[0041] In this embodiment, a rubber sleeve (not shown in the figure) is also fitted onto the outer surface of the roller 6. The rubber sleeve contacts the modular track 2 instead of the roller 6. The material of the rubber sleeve can be, but is not limited to, natural rubber, silicone rubber, or polyurethane. The surface of the rubber sleeve usually has a textured design, which can increase the friction between the roller 6 and the contact surface (the arc-shaped groove 17 of the track), prevent slippage, and ensure stable movement of the seat cushion 3. At the same time, it also prevents the metal roller 6 from directly contacting the modular track 2, preventing scratches and protecting the contact surface.

[0042] In addition, the roller 6 can be detachably connected to the seat cushion 3 through the cooperation of the fastening bolt 10 and the fastening nut 11. The roller 6 is a consumable part. When the roller 6 is damaged, it can be replaced separately without replacing the entire seat cushion 3, thus reducing maintenance costs. The roller 6 is sleeved on the fastening bolt 10, and a limit sleeve 12 is also sleeved on the fastening bolt 10. The limit sleeve 12 is cylindrical and coaxial with the roller 6. A mounting plate 13 is fixedly connected to the seat cushion 3. One end of the fastening bolt 10 passes through the mounting plate 13 and is screwed together with the fastening bolt 10. After the fastening bolt 10 is fixed on the mounting plate 13, the limit sleeve 12 is located between the mounting plate 13 and the roller 6.

[0043] During installation, first, the roller 6 and the limiting sleeve 12 are fitted onto the fastening bolt 10. Then, one end of the fastening bolt 10 is passed through the mounting plate 13 and engaged with the fastening nut 11, relying on the screw force to fix the fastening bolt 10. The position of the roller 6 corresponds to the position of the arc-shaped slide groove 17. When the seat cushion 3 moves, the roller 6 can rotate around the fastening bolt 10 as the axis of rotation. When the roller 6 rotates, it is restricted by the limiting sleeve 12 and will not shift laterally on the fastening bolt 10, ensuring the relative position of the roller 6 and the arc-shaped slide groove 17.

[0044] In some embodiments, the modular track 2 is detachably connected to the rowing machine body 1. The bottom of the rowing machine body 1 is symmetrically provided with base plates 14, with a gap between the two base plates 14. A protrusion 4 at one end of the modular track 2 is located between the two base plates 14. The base plates 14 are respectively connected to a T-shaped shaft 15, a positioning cylinder 16, and a pin (not shown in the figure). Two positioning cylinders 16 are provided, located on either side of the protrusion 4. The T-shaped shaft 15 has a T-shaped cross-section. One end of the T-shaped shaft 15 passes through the base plate 14, the positioning cylinder 16, and the protrusion 4 simultaneously. The pin is inserted into the other end of the T-shaped shaft 15 (a corresponding hole is pre-drilled at the end of the T-shaped shaft 15) and is used to prevent the T-shaped shaft 15 from detaching from the two base plates 14.

[0045] During installation, first place the protrusion 4 at one end of the modular track 2 between the two base plates 14, and simultaneously place the two positioning cylinders 16 on both sides of the protrusion 4. Next, pass one end of the T-shaped shaft 15 through one base plate 14, the two positioning cylinders 16, and the protrusion 4, then exit through the other base plate 14. Finally, insert the pin into the end of the T-shaped shaft 15, preventing it from detaching from the base plate 14 under static friction. The protrusion 4 can rotate around the T-shaped shaft 15 as a pivot point without interfering with the folding and bending of the entire modular track 2.

[0046] In addition, combined Figure 4The rowing machine body 1 is also fixedly equipped with two support pads 19 at its bottom. These two support pads 19 are symmetrically distributed and are used to make contact with the ground. They are made of non-slip material, such as patterned steel plate. During exercise, the rowing machine body 1 will also experience corresponding reaction forces. The support pads 19 increase the contact area and static friction between the entire rowing machine body 1 and the ground, thereby improving the stability of the rowing machine and ensuring normal exercise for the user.

[0047] The implementation principle of the flexible, foldable rowing device according to this application embodiment is as follows: A segmented modular metal track is used, with adjacent track joints 20 connected by bearings or universal joints to ensure smooth bending and folding between the two track joints 20. The modular track 2 can be laid flat as a normal slide rail. Arc-shaped grooves 17 are provided on the track for the rollers 6 on the seat cushion 3 to slide. The rollers 6 and the arc-shaped grooves 17 cooperate to ensure that the seat cushion 3 does not easily deviate during sliding. When the track is not in use, the track joints 20 can be folded, bent, and rolled up, greatly saving space and suitable for various scenarios, solving the problem of space limitations.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
