Pull rope type exercise equipment for fitness

Abstract

The pull rope type exercise equipment comprises a support main body, a rotating shaft is rotatably installed on the support main body, the rotating shaft is sleeved with two rope wheels, a pull rope is wound around the rope wheels, the two rope wheels are both connected with reset mechanisms, the reset mechanisms are used for driving the rope wheels to rotate and reset, and the rotating shaft is connected with a damping mechanism. The damping mechanism is used for providing rotating resistance for the rotating shaft and can adjust the rotating resistance, the rope wheel and the rotating shaft are in one-way transmission connection through the clutch piece, and when the pull rope is pulled out of the rope wheel, the rope wheel can drive the rotating shaft to rotate together through the clutch piece. When the reset mechanism drives the rope wheel to rotate and take up the pulled-out pull rope, the clutch piece breaks transmission between the rope wheel and the rotating shaft, the damping mechanism does not provide rotation resistance for rotation of the rope wheel when the pull rope is released through the clutch piece arranged between the rope wheel and the rotating shaft, and therefore rope take-up is smoother; and the two rope wheels can be arranged on the same rotating shaft and share one damping mechanism, so that the cost is reduced.

Swimming is a sport that requires very professional training and consumes a lot of physical energy. Especially for beginners, if they go swimming without professional training and mastering swimming skills, personal safety accidents may occur. Therefore, an auxiliary training equipment that can simulate underwater swimming movements before going into the water is very important for beginners.

[0004] However, in the process of the reset mechanism driving the rope winding wheel to rotate and reset, the rope winding wheel will also drive the friction wheel to rotate through the rotating shaft connected to it, so that the friction wheel and the friction member also provide rotational resistance during the rope collection process, which may easily cause the problem of unsmooth rope collection. In addition, this structure requires the rope winding wheels on both sides to be separately set on two rotating shafts for rotation, and each of them needs to be separately configured with a set of friction wheels and friction members, which increases the cost.

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0038] Figure 1-Figure 17 As shown, the rope-pulling exercise equipment for fitness comprises a bracket body 1, on which a rotating shaft 21 is rotatably mounted, two rope pulleys 19 are sleeved on the rotating shaft 21, and a pull rope 8 is wound around the rope pulleys 19. Both rope pulleys 19 are connected to a reset mechanism 17, which is used to drive the rope pulleys 19 to rotate and reset, and the rotating shaft 21 is connected to a damping mechanism 18, which is used to provide rotation resistance to the rotating shaft 21 and can adjust the size of the rotation resistance, and the rope pulley 19 is connected to the rotating shaft 21 through a one-way transmission connection via a clutch.

[0039] When the pull rope 8 is pulled out from the rope pulley 19 by external force, the rope pulley 19 is driven by the pulled out pull rope 8 to rotate in the forward direction, and at the same time, the rope pulley 19 drives the rotating shaft 21 to rotate together through the clutch. When the rotating shaft 21 rotates, the damping mechanism 18 provides rotational resistance to the rotation of the rotating shaft 21 and the rope pulley 19; when the pull rope 8 is released, the reset mechanism 17 drives the rope pulley 19 to rotate in the opposite direction, and the rope pulley 19 retracts the pulled out pull rope 8. At this time, the clutch disconnects the transmission between the rope pulley 19 and the rotating shaft 21, the rotating shaft 21 does not rotate with the rope pulley 19, and the damping mechanism 18 does not provide rotational resistance to the rotation of the rope pulley 19.

[0040] By setting a clutch between the rope wheel 19 and the rotating shaft 21, the damping mechanism 18 does not provide rotational resistance to the rotation of the rope wheel 19 when the pull rope 8 is released, thereby making the rope collection smoother and allowing two rope wheels 19 to be set on the same rotating shaft 21 to share a damping mechanism 18, thereby reducing costs.

[0041] Figure 1 , Fig.17 As shown, the working principle is: the exerciser holds the force-bearing ends of the two pull ropes 8 with both hands respectively, pulls the pull ropes 8 outward with one hand, and loosens the pull ropes 8 with the other hand. When the pull ropes 8 are pulled out, the damping mechanism 18 provides rotational resistance to the rotating shaft 21, and the rotating shaft 21 transmits the rotational resistance to the pulley 19, so that the movement of the pull ropes 8 is resisted to achieve strength training. The loosened pull ropes 8 are retracted by the reverse rotation of the pulley 19. The two hands perform strength training by continuously and alternately pulling the pull ropes 8 on both sides, so as to simulate various types of sports for training, including simulated training using resistance methods such as simulated swimming training and rowing training.

[0042] Preferably, the clutch member is a one-way bearing 27. The one-way bearing 27 is an existing conventional structure, such as a one-way bearing of brand muh and model CSK.

[0043] Figure 4-Figure 7 As shown, two first mounting seats 22 are provided on the bracket body 1, and the two first mounting seats 22 are fixedly installed on the bracket body 1 by bolts. Bearing holes 29 are provided on the two first mounting seats 22, and support bearings 30 are installed in the bearing holes 29. The rotating shaft 21 passes through the inner rings of the support bearings 30 installed on the two first mounting seats 22, and the support bearings 30 support the rotating shaft 21 so that the rotating shaft 21 can be rotatably connected to the bracket body 1.

[0044] Figure 8-Figure 15As shown, the damping mechanism 18 includes a friction wheel 23 fixed on the rotating shaft 21 and an adjustment assembly 24 matched with the friction wheel 23, the adjustment assembly 24 includes a left caliper body 46, a right caliper body 43, an adjustment screw 40 and an adjustment nut 15, the left caliper body 46 and the right caliper body 43 are pivotally connected by a pivot 35, the right caliper body 43 has a first clamping end 31 and a first adjustment end 56, the portion of the right caliper body 43 from the rotation point to the first clamping end 31 serves as a first clamping arm 38, and the portion from the rotation point to the first adjustment end 56 serves as a first adjustment arm 36, the left caliper body 46 has a second clamping end 44 and a second adjustment end 57, and the portion of the left caliper body 46 from the rotation point to the second clamping end 44 serves as a second clamping arm 38. 9. The portion from the rotation point to the second adjustment end 57 serves as the second adjustment arm 37. The first clamping end 31 is opposite to the second clamping end 44, and the inner sides of both are provided with a contact portion for contacting and rubbing with the friction wheel 23. A clamping opening 34 for inserting the friction wheel 23 is formed between the contact portion on the first clamping end 31 and the contact portion on the second clamping end 44. The first adjustment end 56 is opposite to the second adjustment end 57. The adjusting screw 40 is connected to the first adjustment end 56. The second adjustment end 57 is provided with a through hole 45 for the adjusting screw 40 to pass through. The adjusting screw 40 passes through the through hole 45 and is threadedly connected to the adjusting nut 15. The width of the clamping opening 34 can be changed by rotating the adjusting nut 15 along the adjusting screw 40.

[0045] Figure 7 As shown, the contact portion arranged on the clamping end contacts and presses on the end face of the friction wheel 23. When the rotating shaft 21 drives the friction wheel 23 to rotate, the friction force between the contact portion and the rotating friction wheel 23 serves as the rotation resistance provided to the rotating shaft 21. When the width of the clamp 34 is changed by rotating the adjusting nut 15 along the adjusting screw 40, the pressure of the contact portion contacting and pressing on the friction wheel 23 will change, thereby changing the friction force between the friction wheel 23 and the contact portion to achieve the effect of adjusting the rotation resistance. By adjusting the size of the rotation resistance applied to the rotating shaft 21, the needs of different exercisers for strength training can be met, making it more applicable. Exercisers can choose the size of the resistance according to their own physical fitness to make the exercise more efficient.

[0046] Preferably, the left caliper body 46 and the right caliper body 43 are arranged alternately, and the staggered positions are pivotally connected together by a pivot 35. When the adjusting nut 15 is rotated and adjusted along the adjusting screw 40, the adjusting nut 15 is rotated toward the end of the adjusting screw 40 connected to the first adjusting end 56, and the adjusting nut 15 is pressed on the outer side of the second adjusting end 57 of the left caliper body 46, and pushes the second adjusting end 57 to approach the first adjusting end 56. In the process of the first adjusting end 56 and the second adjusting end 57 approaching, the left caliper body 46 and the right caliper body 43 rotate around the pivot 35, so that the first clamping end 31 is close to the second clamping end 44, thereby reducing the width of the clamping opening 34, so as to increase the pressure of the contact part on the friction wheel 23, thereby increasing the rotational resistance encountered by the rotating shaft 21 when it rotates.

[0047] A return spring is provided between the left caliper body 46 and the right caliper body 43. The return spring acts on the left caliper body 46 and the right caliper body 43 to make the first clamping end 31 and the second clamping end 44 have a movement tendency to open to both sides, so that when the adjustment nut 15 is screwed out toward the end of the adjustment screw 40 away from the first adjustment end 56, the return spring drives the left caliper body 46 and the right caliper body 43 to rotate and reset around the pivot 35, so that the first clamping end 31 and the second clamping end 44 are opened to both sides, and the first adjustment end 56 and the second adjustment end 57 are also opened to both sides, so that the outer side of the second adjustment end 57 is always pressed against the adjustment nut 15, and the return spring acts on the left caliper body 46 and the right caliper body 43, so that the left caliper body 46 and the right caliper body 43 are always subjected to an opening force, so that the first clamping end 31 and the second clamping end 44 can be maintained at the adjusted width, so that the rotation resistance of the rotating shaft 21 is more stable. The return spring can be a torsion spring.

[0048] Fig.14 , Fig.15 As shown, the bracket body 1 is provided with a mounting hole 54 for installing the pivot 35, and the pivot 35 includes a shaft body 53 and a support column 55 arranged in the middle of the shaft body 53. The diameter of the support column 55 is larger than the diameter of the shaft body 53, and the upper and lower ends of the shaft body 53 are provided with external threads. The shaft body portion located below the support column 55 passes through the mounting hole 54 and the lower end surface of the support column 55 rests on the bracket body 1. The lower end of the shaft body 53 passes through the mounting hole 54 and is threadedly connected with the lower mounting nut 52. The left clamp body 46 and the right clamp body 43 are sleeved on the shaft body portion above the support column 55 for rotation, and the upper end of the shaft body 53 is threadedly connected with the upper mounting nut 41 for limiting the left clamp body 46 and the right clamp body 43.

[0049] Fig.12 , Fig.13As shown, the adjusting screw 40 is connected to the first adjusting end 56 through the mounting bolt 47 and the first mounting nut 48. A flat connecting plate 50 is fixedly provided at one end of the adjusting screw 40. The connecting plate 50 is provided with a first connecting hole 51 for the mounting bolt 47 to pass through. The first adjusting end 56 is provided with a second connecting hole 49 for the mounting bolt 47 to pass through. The mounting bolt 47 passes through the first connecting hole 51 and the second connecting hole 49 and is threadedly connected to the first mounting nut 48. The rod body of the mounting bolt 47 includes a smooth rod and a threaded rod. The connecting plate 50 and the first adjusting end 56 are sleeved on the smooth rod.

[0050] A gap is provided between the through hole 45 and the adjusting screw 40 passing therethrough for the adjusting screw 40 to move therein, so that when the adjusting nut 15 is screwed in or out along the adjusting screw 40 to rotate the left caliper body 46 and the right caliper body 43, the adjusting screw 40 will not get stuck with the inner wall of the through hole 45, causing the left caliper body 46 and the right caliper body 43 to be unable to rotate relative to each other.

[0051] At least one raised rotating protrusion 42 is provided on the side wall of the adjusting nut 15 for manual rotation of the adjusting nut 15. Preferably, the adjusting nut 15 is cylindrical in shape, and two rotating protrusions 42 are provided in a ring array on the circumferential outer wall of the adjusting nut 15, so as to facilitate manual rotation of the adjusting nut 15 without the need for external tools.

[0052] Fig.11 As shown, a second mounting seat 32 is fixed on the inner side of the first clamping end 31 and the second clamping end 44, and a friction plate 33 is detachably fixed on the second mounting seat 32. The friction plate 33 serves as a contact portion for contact and friction with the friction wheel 23. The friction plate 33 is arc-shaped and is used to contact the outer edge of one end surface of the friction wheel 23. The arc-shaped arrangement of the friction plate 33 increases the contact area between the friction wheel 23 and the friction plate 33, and the detachable friction plate 33 is easy to replace after wear.

[0053] Preferably, the friction wheel 23 is arranged between the two rope wheels 19 .

[0054] Figure 5 , Figure 8 , Fig.16 As shown, the reset mechanism 17 includes an elastic rope 26, a recovery wheel 28 for winding the elastic rope 26, and a guide wheel for guiding the elastic rope 26. The recovery wheel 28 is coaxial with the rope wheel 19 and the two are fixed. One end of the elastic rope 26 is connected to the recovery wheel 28, and the other end of the elastic rope 26 is connected to the bracket body 1. The elastic rope 26 is wound around the guide wheel. The guide wheel tensions the elastic rope 26 and changes the direction of the elastic rope 26. When the pull rope 8 is pulled out from the rope wheel 19, the elastic rope 26 is stretched and wound around the recovery wheel 28 as the recovery wheel 28 rotates. When the pulled pull rope 8 is released, the elastic rope 26 elastically retracts to drive the recovery wheel 28 and the rope wheel 19 to rotate, and the rope wheel 19 retracts the pulled pull rope 8.

[0055] Since the elasticity of the elastic rope 26 mainly depends on the flexibility and ductility of the material, the elastic force of the elastic rope 26 acts on the recovery wheel 28 to drive the recovery wheel 28 to rotate more softly and smoothly, so that the rope wheel 19 is not likely to cause strain to the exerciser when retracting the pull rope 8, and the comfort is better. In addition, the elastic rope 26 will not break due to fatigue, and it is safer to use. If it becomes loose after long-term use, it is also easier to replace and maintain it later. The length and thickness of the elastic rope 26 determine the length to which the elastic rope 26 can be stretched. The elastic rope 26 is stretched and then wrapped around the recovery wheel 28 as a reset structure, so that the rope wheel 19 and the recovery wheel 28 can rotate more times, so that the maximum length of the pull rope 8 can be set longer, thereby meeting the needs of simulated swimming training and rowing training.

[0056] The recovery wheel 28 is also sleeved on the rotating shaft 21. Preferably, the recovery wheel 28 and the rope pulley 19 are integrally formed. For example, two annular rope winding grooves are processed on the circumferential outer wall of the cylinder to form the above-mentioned recovery wheel 28 and rope pulley 19. The recovery wheel 28 and the rope pulley 19 are supported by two one-way bearings 27 between the rotating shaft 21.

[0057] Fig.16 As shown, the guide wheels include a plurality of upper guide wheels 4 and a plurality of lower guide wheels 25, and the upper guide wheels 4 and the lower guide wheels 25 are arranged on the bracket body 1 in an upper and lower distribution manner, and the upper guide wheels 4 and the lower guide wheels 25 are staggered, and the elastic rope 26 is staggered around the upper guide wheels 4 and the lower guide wheels 25. By arranging a plurality of upper guide wheels 4 and the lower guide wheels 25, the elastic rope 26 is wound up and down between the upper guide wheels 4 and the lower guide wheels 25 to ensure the length of the elastic rope 26, thereby meeting the demand for the elastic rope 26 to be stretched and wound up, and the upper and lower winding method makes the elastic rope 26 more compact and neatly arranged to ensure smooth stretching and retraction of the elastic rope 26.

[0058] The circumferential wheel surface of the last guide wheel around which the elastic rope 26 passes is opposite to the circumferential wheel surface of the recovery wheel 28 , so that the recovery wheel 28 can rotate and reel in the elastic rope 26 more smoothly.

[0059] The axis center lines of the upper guide wheel 4 and the lower guide wheel 25 are parallel to the axis center lines of the recovery wheel 28 and the rope wheel 19.

[0060] Preferably, there are four upper guide wheels 4, which are coaxially arranged and rotate independently of each other, and there are four lower guide wheels 25, which are coaxially arranged and rotate independently of each other.

[0061] The fixed end of the pull rope 8 is connected to the rope wheel 19, and the force-bearing end of the pull rope 8 is connected with a handle 10, through which the pull rope 8 is pulled. The handle 10 is connected to the end of the pull rope 8 by a connecting ring 9.

[0062] Figure 5 As shown, the bracket body 1 is provided with two swing frames 7 that swing around a vertical axis. The swing frames 7 can swing left and right. The swing frames 7 are provided with guide pulleys 11. The force-bearing ends of the pull rope 8 wound on the rope wheels 19 on both sides respectively pass around the guide pulleys 11 on the two swing frames 7. When the exerciser holds the handles 10 with both hands to pull the pull ropes 8 on both sides, the swing frames 7 swing left and right with the movement of the hands, making the rope output smoother.
