[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a foldable rowing machine to meet the needs of users.

[0004] To achieve the above objectives, this utility model provides a foldable rowing machine comprising a first base adapted for mounting a resistance device and a second base adapted for slidably supporting the seat.

[0005] The first base includes two parallel first longitudinal rods, each first longitudinal rod having a first distal end and a first proximal end, with a first support plate fitted between the two first proximal ends. The second base includes two parallel second longitudinal rods, each second longitudinal rod having a second distal end and a second proximal end, with a second support plate fitted between the two second proximal ends. The first support plate and the second support plate are rotatably connected by a hinge device.

[0006] The second base includes a flattened state and a folded state. In the flattened state, the angle between the first base and the second base is 180°. The second base can be flipped upward at least 90° from the flattened state to form a folded state.

[0007] Preferably, in the folded state, the second base can be flipped upwards by 100°-130° from the flat state to form a folded state. This design helps to shift the center of gravity of the rowing machine forward and downward, making the center of gravity more concentrated and helping to improve the overall stability.

[0008] Preferably, in the unfolded state, the first support plate and the second support plate are arranged parallel to or overlapped, and the first support plate and the second support plate are adapted to be fixed relative to each other by a locking knob.

[0009] Specifically, the first support plate and the second support plate each have an internal threaded hole. The locking knob includes a knob part and an external thread that adapts to the threaded hole. In the unfolded state, the first threaded hole and the second threaded hole are aligned. The locking knob achieves relative fixation between the first support plate and the second support plate by engaging the internal threaded hole with its external thread.

[0010] By setting up the first support plate and the second support plate: firstly, it provides an installation structure for the hinge device, thereby enabling the rotational engagement of the first base and the second base, and also helps to conceal the hinge device; secondly, the locking knob enables the first base and the second base to be locked in the flat state, reducing unnecessary shaking during exercise; and thirdly, it strengthens the connection strength between the first vertical bar and the second vertical bar, thereby enhancing the structural strength of the first base and the second base.

[0011] Preferably, the first longitudinal bar includes a first inner side facing each other, and the second longitudinal bar includes a second inner side facing each other. The first support plate is fixedly mounted to the first inner side on both sides by a first wing plate, and the second support plate is fixedly mounted to the second inner side on both sides by a second wing plate. The hinge devices do not extend beyond the upper surface of the first longitudinal bar and the upper surface of the second longitudinal bar.

[0012] Preferably, the first proximal end has a guide arc surface, a first stop surface and a second stop surface, and the second proximal end has a guide arc portion and a first mating surface.

[0013] In the flattened state, the first stop surface abuts against the first mating surface to restrict the second base from further flipping downwards, and the guide arc surface and the first stop surface are adapted to support the second proximal end; during the upward flipping of the second base, the guide arc surface and the guide arc portion roll together, thereby allowing the second base to roll smoothly along a predetermined curved path during folding, which reduces friction and resistance during folding, making the folding action smoother, and at the same time, rolling can disperse contact stress and reduce local wear; in the folded state, the second stop surface is adapted to abut against the upper surface of the second longitudinal bar to indicate that the folding is in place, and the guide arc surface and the second stop surface are adapted to support the second proximal end.

[0014] Preferably, the machine also includes a first leg suitable for supporting the first distal end, a second leg suitable for supporting the first proximal end, and a third leg suitable for supporting the second distal end. In the flattened state, the first leg, the second leg, and the third leg together support the rowing machine. In the folded state, the first leg and the second leg together support the rowing machine.

[0015] Preferably, the second stop surface is adapted to abut against the second longitudinal rod to limit the rotation range of the second base, wherein: the second stop surface is a cross-section perpendicular to the first longitudinal rod, one end of the second stop surface is tangent to the guide arc surface, and the upper surface of the second longitudinal rod is adapted to abut against the intersection of the second stop surface and the upper surface of the first longitudinal rod; or, the second stop surface is an inclined surface or a curved surface, and the upper surface of the second longitudinal rod is adapted to abut only against the second stop surface.

[0016] Preferably, the guide arc portion is semi-cylindrical, and the first mating surface intersects with the guide arc portion and is arranged radially along the guide arc portion.

[0017] Preferably, the first support plate is arranged perpendicular to the first longitudinal bar, or the first support plate is arranged parallel to the first stop surface.

[0018] Preferably, the first base defines a storage area adjacent to the first proximal end, and in the folded state, the seat is adapted to slide down to the second proximal end under the action of gravity, with at least a portion of the seat extending into the storage area.

[0019] This design lowers the center of gravity of the second base when folded, which helps maintain stability, and also makes the structure more compact, reducing space occupation.

[0020] Preferably, the seat includes a seat body and a sliding seat. The sliding seat includes a top plate adapted to support the seat body and two side plates adapted to slide with the second longitudinal bar. In the folded state, the width of the seat body and the sliding seat is less than the distance between the two first longitudinal bars, so that the seat extends into the storage area in the folded state.

[0021] Preferably, the side plate is fitted with a first pulley on its outer side, and the upper surface of the second longitudinal rod is provided with a first slide rail suitable for the first pulley to slide back and forth. In the folded state, the first pulley is adapted to abut against the upper surface of the first longitudinal rod, increasing the support area and improving the stability in the folded state; and / or, the side plate is fitted with a second pulley on its inner side, and the second inner side is provided with a second slide rail suitable for the second pulley to slide back and forth. The two ends of the second slide rail are also provided with stop seats, and the stop seats have stop arc surfaces suitable for fitting the second pulley.

[0022] The beneficial effects of this utility model are:

[0023] (1) The first base and the second base are folded by the hinge of the first support plate and the second support plate, thereby realizing the compact storage of the rowing machine, reducing space occupation, and making it convenient for home users to store. The second base is flipped upward at least 90° to help lower and move the center of gravity forward, which helps to maintain the stability of the folded state.

[0024] (2) A first support plate and a second support plate, along with a locking knob, were designed to achieve a stable connection and flexible adjustment between the bases, reducing unnecessary shaking during exercise.

[0025] (3) The rolling cooperation between the guide arc surface and the guide arc part makes the folding action smoother, and the support point in the folding state is increased by the support cooperation between the second stop surface and the second longitudinal rod, which improves the stability of the rowing machine in the folding state.

[0026] (4) The design of the sliding seat and the storage area optimize the compactness and stability in the folded state, while improving the user's convenience.

[0027] (5) The design of the first pulley and the second pulley increases the support area and improves the stability in the folded state. At the same time, the cooperation between the pulley and the slide rail provides a smooth sliding experience. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0036] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] like Figure 1-5As shown, a foldable rowing machine includes a first base 100 adapted to mount a resistance device 500 and a second base 200 adapted to slidably support a seat 400. The first base 100 includes two parallel first longitudinal bars 110, each with a first distal end 112 and a first proximal end 113. The second base 200 includes two parallel second longitudinal bars 210, each with a second distal end 212 and a second proximal end 213. The first distal end 112 is supported by a first support leg 120, the first proximal end 113 is supported by a second support leg 130, the second proximal end 213 is supported by the first proximal end 113, and the second distal end 212 is supported by a third support leg 220. A first support plate 140 is fitted between the two first proximal ends 113, and a second support plate 230 is fitted between the two second proximal ends 213. The first support plate 140 and the second support plate 230 are rotatably connected by a hinge device 300. The second base 200 includes a flattened state and a folded state. The second base 200 can be flipped upwards by 130° from the flattened state to form a folded state.

[0038] In this embodiment, the first longitudinal rod 110 includes a first inner side surface 111 facing each other, and the second longitudinal rod 210 includes a second inner side surface 211 facing each other. The first support plate 140 is fixedly mounted to the first inner side surface 111 on both sides via first wing plates 141, and the second support plate 230 is fixedly mounted to the second inner side surface 211 on both sides via second wing plates 232. The hinge devices 300 do not extend beyond the upper surfaces of the first longitudinal rod 110 and the second longitudinal rod 210. Specifically, the first support plate 140 and the second support plate 230 each have an internal threaded hole. The locking knob 231 includes a knob portion and an external thread that adapts to the threaded hole. In the unfolded state, the first threaded hole and the second threaded hole are aligned, and the locking knob 231 achieves relative fixation between the first support plate 140 and the second support plate 230 through the engagement of its external thread with the internal threaded hole. By setting the first support plate 140 and the second support plate 230: firstly, it provides an installation structure for the hinge device 300, thereby enabling the rotational engagement of the first base 100 and the second base 200, and also facilitates the concealment of the hinge device 300; secondly, the locking knob enables the first base 100 and the second base 200 to be locked in the flattened state, reducing unnecessary shaking during exercise; and thirdly, it strengthens the connection strength between the first vertical rod 110 and the second vertical rod 210, thereby enhancing the structural strength of the first base 100 and the second base 200.

[0039] In this embodiment, the first proximal end 113 is formed with a guide arc surface 1131, a first stop surface 1132, and a second stop surface 1133. The first support plate 140 is arranged parallel to the first stop surface 1132. The second stop surface 1133 is a cross-section perpendicular to the first longitudinal rod 110, and one end of the second stop surface 1133 is tangent to the guide arc surface 1131. The second proximal end 213 is formed with a guide arc portion 2131 and a first mating surface 2132. The guide arc portion 2131 is semi-cylindrical, and the first mating surface 2132 intersects with the guide arc portion 2131 and is arranged radially along the guide arc portion 2131.

[0040] In the flattened state, the first stop surface 1132 abuts against the first mating surface 2132 to restrict the second base 200 from further tilting downwards. The included angle between the first base 100 and the second base 200 is 180°. The guide arc surface 1131 and the first stop surface 1132 are adapted to support the second proximal end 213. The first support leg 120, the second support leg 130, and the third support leg 220 jointly support the rowing machine. The first support plate 140 and the second support plate 230 are arranged parallel and coincident, and the first support plate 140 and the second support plate 230 are adapted to be fixed relative to each other by the locking knob 231.

[0041] During the process of flipping the second base 200 from its flattened state upwards, the guide arc surface 1131 and the guide arc portion 2131 roll together, thereby allowing the second base 200 to roll smoothly along a predetermined curved path during the folding process. This reduces friction and resistance during the folding process, making the folding action smoother. At the same time, rolling can disperse contact stress and reduce local wear.

[0042] In the folded state, the second stop surface 1133 is adapted to limit the rotation range of the second base 200, and the upper surface of the second longitudinal rod 210 is adapted to abut against the intersection of the second stop surface 1133 and the upper surface of the first longitudinal rod 110 to indicate that the folding is in place. In some other embodiments, the second stop surface 1133 is an inclined surface or a curved surface, and the upper surface of the second longitudinal rod 210 is adapted to abut only against the second stop surface 1133. The first support leg 120 and the second support leg 130 jointly support the rowing machine. The guide arc surface 1131 and the second stop surface 1133 are adapted to support the second proximal end 213.

[0043] In this embodiment, the first base 100 defines a storage area 150 adjacent to the first proximal end 113. In the folded state, the seat 400 is adapted to slide down to the second proximal end 213 under the influence of gravity, with a portion of the seat 400 extending into the storage area 150. This design, in the folded state, helps to shift the center of gravity of the rowing machine forward and downward, making the center of gravity more concentrated, which is beneficial for maintaining stability, and also makes the structure more compact, reducing space occupation.

[0044] In this embodiment, the seat 400 includes a seat body 410 and a sliding seat 420. The sliding seat 420 includes a top plate 421 adapted to support the seat body 400 and two side plates 422 adapted to slide and engage with the second longitudinal rod 210. In the folded state, the width of the seat body 410 and the sliding seat 420 is less than the distance between the two first longitudinal rods 110, so that the seat 400 can extend into the storage area 150 in the folded state. A first pulley 423 is fitted on the outer side of the side plate 422, and a first slide rail 214 adapted to allow the first pulley 423 to slide back and forth is provided on the upper surface of the second longitudinal rod 210. In the folded state, the first pulley 423 is adapted to abut against the upper surface of the first longitudinal rod 110, increasing the support area and improving the stability in the folded state. The inner side of the side plate 422 is equipped with a second pulley 424, and the second inner side 211 is provided with a second slide rail 215 suitable for the second pulley 424 to slide back and forth. The two ends of the second slide rail 215 are also provided with stop seats 216, and the stop seats 216 have stop arc surfaces suitable for fitting the second pulley 424.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
