Description

Technical Field

[0001] This utility model relates to a sports training device, and more particularly to a damping rope device for fitness. Background Technology

[0002] Currently, to achieve better fitness or rehabilitation results, users typically use fitness equipment. There are various types of fitness equipment, among which rope-assisted reciprocating exercise equipment is widely used in various scenarios such as indoor spaces, residential areas, and parks. For example, swimming trainers simulate underwater swimming movements to assist in the swimming training process.

[0003] Typical damping rope pullers usually have a rope winding wheel and a friction wheel coaxially connected. The rope pulling exercise equipment is equipped with a friction element that abuts against the friction wheel. The rope winding wheel is wound with a rope. The rope winding wheel is connected to a reset mechanism. When the rope is pulled outward by force, the rope winding wheel drives the friction wheel to rotate through the rotating shaft connected to it. The friction between the friction wheel and the friction element provides rotational damping force. When the pulled rope is released, the reset mechanism drives the rope winding wheel to rotate back to reset, so as to rewind the pulled rope.

[0004] However, during the reset process, when the rope-winding wheel is driven to rotate and reset by the reset mechanism, the rope-winding wheel will also drive the friction wheel to rotate through the shaft connected to it. That is, during the rope winding process, the friction wheel and friction components also provide resistance, making the recovery process relatively stuck, which can easily lead to problems with unsmooth rope winding and affect the continuity of exercise. Utility Model Content

That is, during the rope winding process, the friction wheel and friction components also provide resistance, making the recovery process relatively stuck and easily causing problems with unsmooth rope winding, and affecting the continuity of exercise. This utility model provides a damping rope puller for fitness.

[0007] A further preferred embodiment of this invention is that the clutch component is a one-way bearing.

[0008] A further preferred embodiment of this utility model is as follows: the reset mechanism includes an elastic rope. When the rope is pulled out from the pulley, the elastic rope is stretched and wound around the pulley as it rotates. When the pulled rope is released, the elastic rope retracts elastically to make the pulley rotate and retract the pulled rope.

[0009] A further preferred technical solution of this utility model is as follows: the reset mechanism includes a recovery wheel for winding the elastic rope and a guide wheel for guiding the elastic rope. The recovery wheel and the rope wheel are coaxial and fixed together. One end of the elastic rope is connected to the recovery wheel, and the other end of the elastic rope is connected to the support frame. The elastic rope is wound around the guide wheel. The guide wheel assembly tensions the elastic rope and changes the direction of the elastic rope.

[0010] A further preferred embodiment of this utility model is as follows: the support frame is provided with a swing frame that swings around a vertical axis, the swing frame is provided with a guide pulley, and the force-bearing end of the pull rope passes around the guide pulley.

[0011] A further preferred embodiment of this utility model is that a handle is connected to the end of the force-bearing end of the pull rope.

[0012] A further preferred embodiment of this utility model is as follows: the support frame is provided with two mounting seats, and each mounting seat is equipped with a support bearing, with the rotating shaft passing through the inner ring of the support bearing.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0027] Figures 1-6 As shown, a damping rope puller for fitness includes a support frame 1, on which a rotating shaft 13 is rotatably mounted. A rope pulley 3 is fitted onto the rotating shaft 13, and a pull rope 4 is wound around the rope pulley 3. The rope pulley 3 is connected to a reset mechanism 11, which drives the rope pulley 3 to rotate and reset. A damping mechanism 10 is connected to the rotating shaft 13, which provides rotational resistance to the rotating shaft 13. The rope pulley 3 and the rotating shaft 13 are connected by a clutch for one-way transmission. This patented structure can be applied to rowing training equipment, swimming training equipment, and other exercise equipment.

[0028] When the pull rope 4 is pulled out of the pulley 3 by an external force, the pulley 3 is driven to rotate in the forward direction by the pulled rope 4. At the same time, the pulley 3 drives the rotating shaft 13 to rotate together through the clutch. When the rotating shaft 13 rotates, the damping mechanism 10 provides rotational resistance to the rotating shaft 13. The rotational resistance is transmitted to the pulley 3 through the clutch. When the pull rope 4 is released, the reset mechanism 11 drives the pulley 3 to rotate in the reverse direction. The pulley 3 retracts the pulled rope 4. At this time, the clutch disconnects the transmission between the pulley 3 and the rotating shaft 13. The rotating shaft 13 does not rotate with the pulley 3, and the damping mechanism 10 does not provide rotational resistance to the rotation of the pulley 3.

[0029] The clutch between the rope pulley 3 and the shaft 13 ensures that the damping mechanism 10 does not provide rotational resistance to the rotation of the rope pulley 3 when the rope 4 is released, thus making the rope winding smoother and providing a more fluid exercise experience.

[0030] Preferably, the clutch is a one-way bearing 17, which is a conventional structure, such as a one-way bearing of the brand muh and model CSK.

[0031] Figure 2 As shown, the support frame 1 is provided with two first mounting seats 12. The two first mounting seats 12 are fixedly mounted on the support frame 1 by bolts. Each of the two first mounting seats 12 is provided with a bearing hole 19. A support bearing 20 is installed in the bearing hole 19. The rotating shaft 13 passes through the inner ring of the support bearing 20 installed on the two first mounting seats 12. The support bearing 20 supports the rotating shaft 13, so that the rotating shaft 13 is rotatably connected to the support frame 1.

[0032] Figure 3 , Figure 6 As shown, the damping mechanism 10 includes a friction wheel 18 fixedly connected to the rotating shaft 13 and a friction element disposed on the support frame 1 that contacts the friction wheel 18, and uses the friction force generated by the friction between the friction element and the friction wheel 18 as the rotational resistance.

[0033] The rotational resistance of the damping mechanism 10 is adjustable. Preferably, the damping mechanism 10 includes an adjustment assembly that cooperates with the friction wheel 18. The adjustment assembly includes a left clamp body, a right clamp body, an adjustment screw 34, and an adjustment nut 32. The left and right clamp bodies are pivotally connected by a pivot 26. The right clamp body has a first clamping end 24 and a first adjusting end 36. The portion of the right clamp body from the rotation point to the first clamping end 24 serves as a first clamping arm 25, and the portion from the rotation point to the first adjusting end 36 serves as a first adjusting arm 29. The left clamp body has a second clamping end and a second adjusting end 31. The portion of the left clamp body from the rotation point to the second clamping end serves as a second clamping arm 39. The portion leading to the second adjustment end 31 serves as the second adjustment arm 30. The first clamping end 24 is opposite to the second clamping end, and both have friction elements on their inner sides that rub against the friction wheel 18. The friction elements on the first clamping end 24 and the friction elements on the second clamping end form a clamping opening 23 for the friction wheel 18 to be inserted. The first adjustment end 36 is opposite to the second adjustment end 31. An adjustment screw 34 is connected to the first adjustment end 36. The second adjustment end 31 has a through hole through which the adjustment screw 34 passes. The adjustment screw 34 passes through the through hole and is threadedly connected to the adjustment nut 32. The width of the clamping opening 23 can be changed by rotating the adjustment nut 32 along the adjustment screw 34.

[0034] The friction element on the clamping end presses against the end face of the friction wheel 18. When the rotating shaft 13 drives the friction wheel 18 to rotate, the friction force between the friction element and the rotating friction wheel 18 provides rotational resistance to the rotating shaft 13. By turning the adjusting nut 32 along the adjusting screw 34 to change the width of the clamp 23, the pressure of the friction element pressing on the friction wheel 18 will change, thereby changing the friction force between the friction wheel 18 and the friction element, so as to adjust the rotational resistance. By adjusting the magnitude of the rotational resistance applied to the rotating shaft 13, the needs of different exercisers for strength training can be met, making it more applicable. Exercisers can choose the magnitude of resistance according to their own physical fitness to make the training more efficient.

[0035] Preferably, the left and right clamps are staggered, and the staggered positions are pivotally connected together via pivot 26. When adjusting by rotating the adjusting nut 32 along the adjusting screw 34, the adjusting nut 32 is screwed toward the end of the adjusting screw 34 connected to the first adjusting end 36. The adjusting nut 32 presses against the outside of the second adjusting end 31 of the left clamp and pushes the second adjusting end 31 toward the first adjusting end 36. During the process of the first adjusting end 36 and the second adjusting end 31 approaching each other, the left and right clamps rotate around the pivot 26, causing the first clamping end 24 to approach the second clamping end, thereby reducing the width of the clamping jaw 23, increasing the pressure of the friction element on the friction wheel 18, and thus increasing the rotational resistance experienced by the rotating shaft 13 when it rotates.

[0036] A return spring is provided between the left and right clamping bodies. The return spring acts on the left and right clamping bodies, causing the first clamping end 24 and the second clamping end to tend to open to both sides. When the adjusting nut 32 is screwed out towards the end of the adjusting screw 34 away from the first adjusting end 36, the return spring drives the left and right clamping bodies to rotate and return to their original position around the pivot 26. This causes the first clamping end 24 and the second clamping end to open to both sides, and the first adjusting end 36 and the second adjusting end 31 also open to both sides. This ensures that the outer side of the second adjusting end 31 is always tightly pressed against the adjusting nut 32. Through the return spring acting on the left and right clamping bodies, the left and right clamping bodies are always subjected to an opening force, thus maintaining the first clamping end 24 and the second clamping end at the adjusted width, making the rotational resistance on the rotating shaft 13 more stable. The return spring can be a torsion spring.

[0037] The support frame 1 is provided with a mounting hole for mounting the pivot 26. The pivot 26 includes a shaft and a support column located in the middle of the shaft. The diameter of the support column is larger than the diameter of the shaft. Both the upper and lower ends of the shaft are provided with external threads. The shaft part located below the support column passes through the mounting hole and the lower end face of the support column abuts against the support frame 1. The lower end of the shaft passing through the mounting hole is threadedly connected to the lower mounting nut 28. The left and right clamps are rotated on the shaft part above the support column. The upper end of the shaft is threadedly connected to the upper mounting nut 27 to limit the left and right clamps.

[0038] The adjusting screw 34 is connected to the first adjusting end 36 via the mounting bolt 37 and the first mounting nut 38. One end of the adjusting screw 34 is fixed with a flat connecting plate 35. The connecting plate 35 has a first connecting hole for the mounting bolt 37 to pass through. The first adjusting end 36 has a second connecting hole for the mounting bolt 37 to pass through. The mounting bolt 37 passes through the first connecting hole and the second connecting hole and is threadedly connected to the first mounting nut 38. The rod part of the mounting bolt 37 includes a smooth rod and a threaded rod. The connecting plate 35 and the first adjusting end 36 are fitted onto the smooth rod.

[0039] A gap is provided between the through hole and the adjusting screw 34 through which it passes, allowing the adjusting screw 34 to move within it. This ensures that when the adjusting nut 32 is screwed in or out along the adjusting screw 34 to rotate the left and right clamps, the adjusting screw 34 will not get stuck against the inner wall of the through hole, preventing the left and right clamps from rotating relative to each other.

[0040] The adjusting nut 32 has at least one raised rotating protrusion 33 on its side wall for manual rotation. Preferably, the adjusting nut 32 is cylindrical in shape, and two rotating protrusions 33 are arranged in a ring on the outer wall of the adjusting nut 32 to facilitate manual rotation of the adjusting nut 32 without the need for external tools.

[0041] A second mounting base 21 is fixed on the inner side of both the first clamping end 24 and the second clamping end. A friction plate 22 is fixed on the second mounting base 21. The friction plate 22 is a friction component that contacts and rubs with the friction wheel 18. The friction plate 22 is arc-shaped and is used to contact the outer edge of one end face of the friction wheel 18. The arc shape of the friction plate 22 increases the contact area between the friction wheel 18 and the friction plate 22.

[0042] The friction plate 22 can be detachably mounted on the second mounting base 21 for easy replacement and maintenance later.

[0043] Figures 1-4 As shown, the reset mechanism 11 includes an elastic rope 15. When the pull rope 4 is pulled out from the pulley 3, the elastic rope 15 is stretched and forms a winding as the pulley 3 rotates. When the pulled rope 4 is released, the elastic rope 15 elastically retracts to make the pulley 3 rotate and retract the pulled rope 4.

[0044] Preferably, the reset mechanism 11 further includes a recovery wheel 2 for winding the elastic rope 15 and a guide wheel for guiding the elastic rope 15. The recovery wheel 2 and the rope wheel 3 are coaxial and fixed together. One end of the elastic rope 15 is connected to the recovery wheel 2, and the other end of the elastic rope 15 is connected to the support frame 1. The elastic rope 15 is wound around the guide wheel. The guide wheel tensions the elastic rope 15 and changes the direction of the elastic rope 15. When the pull rope 4 is pulled out from the rope wheel 3, the elastic rope 15 is stretched and wound around the recovery wheel 2 as the recovery wheel 2 rotates. When the pulled rope 4 is released, the elastic rope 15 elastically retracts to drive the recovery wheel 2 and the rope wheel 3 to rotate. The rope wheel 3 retracts the pulled rope 4.

[0045] Since the elasticity of the elastic rope 15 mainly relies on the flexibility and extensibility of the material, the elastic force of the elastic rope 15 acts on the return wheel 2, driving the return wheel 2 to rotate more smoothly and gently. This makes it less likely for the rope wheel 3 to cause strain to the exerciser when retracting the rope 4, resulting in better comfort. Furthermore, the elastic rope 15 will not break due to fatigue, making it safer to use. If it loosens after prolonged use, it is also easier to replace and maintain later. The length and thickness of the elastic rope 15 determine the length to which it can be stretched. The way the elastic rope 15 is stretched and wrapped around the return wheel 2 serves as a reset structure, allowing the rope wheel 3 and the return wheel 2 to rotate more times. This allows the maximum length of the rope 4 to be set longer, thus meeting the needs of simulated swimming and rowing training.

[0046] The recovery wheel 2 is also fitted onto the rotating shaft 13. The rope wheel 3 has a first winding groove on its circumference for winding the pull rope 4, and a second winding groove on its circumference for winding the elastic rope 15. Preferably, the recovery wheel 2 and the rope wheel 3 are integrally formed, for example, by machining two annular winding grooves on the outer circumferential wall of a cylinder to form the aforementioned recovery wheel 2 and rope wheel 3. The recovery wheel 2 and rope wheel 3 are supported by two one-way bearings 17 between themselves and the rotating shaft 13.

[0047] The guide wheel includes multiple upper guide wheels 14 and multiple lower guide wheels 16. The upper guide wheels 14 and lower guide wheels 16 are arranged vertically on the support frame 1 and are staggered. The elastic rope 15 is wound vertically and horizontally around the upper guide wheels 14 and lower guide wheels 16. By setting multiple upper guide wheels 14 and lower guide wheels 16, the elastic rope 15 is wound vertically between the upper guide wheels 14 and lower guide wheels 16 to ensure the length of the elastic rope 15, thereby meeting the requirement of the elastic rope 15 being stretched and wound up. The vertical winding method makes the elastic rope 15 more compact and neatly arranged to ensure the smooth stretching and retraction of the elastic rope 15.

[0048] The circumferential surface of the last guide wheel around which the elastic rope 15 passes is opposite to the circumferential surface of the recovery wheel 2, making the recovery wheel 2 rotate more smoothly when winding the elastic rope 15.

[0049] The center lines of the upper guide wheel 14 and the lower guide wheel 16 are parallel to the center lines of the recovery wheel 2 and the rope wheel 3.

[0050] Preferably, there are four upper guide wheels 14, which are coaxially arranged and rotate independently of each other. There are also four lower guide wheels 16, which are coaxially arranged and rotate independently of each other.

[0051] This patent is not limited to the elastic rope 15 being wound around the recovery wheel 2 that is coaxially fixed with the rope wheel 3. It can also be on the extension portion that extends axially from the rope wheel 3, or on the recovery wheel 2 that is connected to the rope wheel 3 in a transmission manner but is not on the same axis. Other methods are also applicable to this patent.

[0052] The fixed end of the pull rope 4 is connected to the pulley 3, and the force-bearing end of the pull rope 4 is connected to a handle 8, which is used to pull the pull rope 4. The handle 8 and the end of the pull rope 4 are connected by a connecting ring 7.

[0053] Figure 5 As shown, the support frame 1 is equipped with a swing frame 9 that swings around a vertical axis. The swing frame 9 can swing left and right. The swing frame 9 is equipped with a guide pulley 5. The force-bearing end of the pull rope 4 wound on the rope wheel 3 passes around the guide pulley 5 on the swing frame 9. When the exerciser holds the handle 8 to pull the pull rope 4, the swing frame 9 swings left and right with the movement of the hand, making the rope release smoother.

[0054] There are two rope wheels 3, both of which are mounted on the rotating shaft 13. There are two sets of reset mechanisms 11, which are respectively connected to the two rope wheels 3. The two sets of reset mechanisms 11 are used to drive the two rope wheels 3 to rotate and reset. The friction wheel 18 is located between the two rope wheels 3. There are two sets of swing frames 9 on the support frame 1. The tension ends of the pull ropes 4 wound on the rope wheels 3 on both sides pass over the guide pulleys 5 on the two swing frames 9 respectively.

[0055] Working principle: The exerciser holds the force-bearing ends of the two pull ropes 4 with both hands. One hand pulls the pull rope 4 outward while the other hand releases it. When the pull rope 4 is pulled out, the damping mechanism 10 provides rotational resistance to the rotating shaft 13, and the rotating shaft 13 transmits the rotational resistance to the rope wheel 3, so that the pull rope 4 is resisted, thus achieving strength training. The released pull rope 4 is pulled back by the reverse rotation of the rope wheel 3. The two hands continuously pull the pull ropes 4 on both sides to carry out strength training, simulating various sports training methods, including simulating the resistance training of swimming and rowing training.

[0056] The swing frame 9 is set on the top of the support frame 1. The bottom of the support frame 1 is provided with two fixed pulleys 6 corresponding to the pull ropes 4 on both sides. The pull ropes 4 pass around the fixed pulleys 6 and then around the guide pulleys 5 on the swing frame 9. The fixed pulleys 6 tension the pull ropes 4 and change the direction of the pull ropes 4.

[0057] The swing frame 9, the rotating shaft 13, and the guide wheel are arranged sequentially from front to back.

The descriptions of the embodiments are only for the purpose of helping to understand this utility model and its core ideas.
