Description

Technical Field

[0001] This utility model relates to the field of pedal machine technology, and more specifically, to a novel stepper. Background Technology

[0002] A stepper is a common indoor fitness device that simulates walking or climbing stairs, providing users with a low-impact aerobic exercise.

[0003] Existing stepper machines typically only exercise the lower body and legs. For upper body muscle training, they usually only add a rope to achieve a basic stretching effect. This lack of intensity is insufficient for users seeking comprehensive fitness, failing to achieve the effect of exercising the entire body. As a result, the stepper machine has limited functionality, affecting the motivation and sustainability of exercise. In view of this, we propose a new type of stepper machine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a new type of stepper to solve the technical problem that current users who pursue comprehensive fitness lack exercise intensity and cannot achieve the effect of exercising the whole body, resulting in the stepper having a single function and affecting the enthusiasm and sustainability of exercise.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a novel stepper, comprising a stepper body, wherein a tensioning mechanism is installed on both the left and right sides of the stepper body;

[0006] The tensioning mechanism includes a base plate connected to the main body of the pedal machine. A vertical cylinder is fixedly installed on the top of the base plate. A movable plate is movably installed inside the vertical cylinder. Limiting grooves are opened on the left and right inner walls of the vertical cylinder. Limiting members that engage with the limiting grooves are fixed on both sides of the movable plate. A spring is fixedly installed on the top of the movable plate. A cylinder cover that fits against the upper end of the spring is installed on the top of the vertical cylinder. Two connecting blocks are symmetrically arranged at the center of the top of the movable plate. Pull ropes that penetrate the cylinder cover are installed on the outer sides of the two connecting blocks.

[0007] This invention increases the upper body stretching structure by setting a stretching mechanism on both sides of the pedal machine body. The cooperation between the movable plate and the spring inside the vertical cylinder can form an upward resistance. The connection with the pull rope makes it convenient for exercisers to perform stretching exercises, thereby increasing the intensity of upper body exercises and meeting the needs of full-body exercisers. This structural combination can improve the functionality of the machine, enhance the exercise effect during stepping, and increase the challenge for exercisers.

[0008] Preferably, the limiting member includes two fixing plates, with a large ball bearing rotatably mounted between the two fixing plates and fitting against the surface of the limiting groove, and small ball bearings rotatably mounted on the opposite sides of the two fixing plates and fitting against the surfaces of the limiting groove on both sides.

[0009] Preferably, the upper ends of the two pull ropes are connected to handles, and the outer wall of the handles is made of rubber.

[0010] Preferably, a plurality of limiting rings are fixedly provided on the wall of the pull rope, and a gravity block is clamped between two adjacent limiting rings.

[0011] Preferably, the gravity block includes a weight portion, one end of which is integrally formed with two elastic clamping portions, and a clamping cavity is formed between the two clamping portions and the weight portion.

[0012] Preferably, a slot is provided on the side wall where the base plate connects to the pedal body, and a pin is inserted between the pedal body and the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model increases the upper body stretching structure by setting a stretching mechanism on both sides of the pedal machine body. The cooperation between the movable plate and the spring inside the vertical cylinder can form an upward resistance. The connection with the pull rope makes it convenient for exercisers to stretch, thereby increasing the intensity of upper body exercise and meeting the needs of full-body exercisers. This structure improves the functionality of the machine, enhances the exercise effect during stepping, and increases the challenge for exercisers.

[0015] 2. This utility model also reduces the resistance of the movable plate moving up and down in the vertical cylinder by using the cooperation of the limiting component and the limiting groove, thereby reducing the noise generated by friction. The large ball bearings set between the fixed plates and the small ball bearings set on both sides can achieve a rolling effect when moving, which can further reduce friction, reduce the impact of noise on exercisers, and enhance the overall structural cooperation effect.

[0022] like Figures 1 to 5 As shown, this utility model relates to a novel stepper, which includes a stepper body 1 and a stretching mechanism 2 installed on both the left and right sides of the stepper body 1; when the foot steps on the stepper body 1 and pulls the stretching mechanism 2, the effect of full-body exercise can be achieved.

[0023] The stretching mechanism 2 includes a base plate 3 connected to the pedal body 1. A vertical cylinder 4 is fixedly mounted on the top of the base plate 3. A movable plate 5 is movably installed inside the vertical cylinder 4. Limiting grooves 401 are opened on the left and right inner walls of the vertical cylinder 4. Limiting members 6 that engage with the limiting grooves 401 are fixed on both the left and right sides of the movable plate 5. A spring 7 is fixedly mounted on the top of the movable plate 5. A cylinder cover 402 that fits against the upper end of the spring 7 is installed on the top of the vertical cylinder 4. Two connecting blocks 501 are symmetrically arranged at the center of the top of the movable plate 5. Pull ropes 8 that penetrate the cylinder cover 402 are installed on the outer sides of the two connecting blocks 501. The position of the vertical cylinder 4 can be fixed by connecting the base plate 3 to the pedal body 1. The movable plate 5 inside the vertical cylinder 4 can move up and down with the cooperation of the spring 7 and the pull ropes 8. The movement causes the spring 7 to contract and generate resistance to achieve the stretching exercise effect. The cooperation between the limiting members 6 on both sides of the movable plate 5 and the limiting grooves 401 can reduce the resistance of the up and down movement, reduce the noise generated by friction, and improve the use effect.

[0024] In an embodiment of this utility model, the limiting member 6 includes two fixing plates 601. A large ball bearing 602 that fits against the groove surface of the limiting groove 401 is rotatably installed between the two fixing plates 601. Small balls bearing 603 that fit against the groove surfaces on both sides of the limiting groove 401 are rotatably provided on the opposite sides of the two fixing plates 601. The design of the large ball bearing 602 and the small ball bearing 603 allows them to rotate due to friction during up and down movement, thereby reducing the noise caused by continuous friction, reducing wear between structures, and enhancing durability.

[0025] In an embodiment of this utility model, the upper ends of the two pull ropes 8 are connected to handles 801, and the outer wall of the handles 801 is made of rubber. The handles 801 are designed to be easy to grip, and the rubber material can achieve the effect of sweat absorption and anti-slip.

[0026] In an embodiment of this utility model, a plurality of limiting rings 802 are fixedly provided on the rope wall of the pull rope 8, and a gravity block 9 is clamped between two adjacent limiting rings 802; the gravity block 9 structure designed between the limiting rings 802 can increase the weight of the pull rope 8, thereby improving the intensity of the stretching exercise, and the clamping installation can facilitate the replacement of gravity blocks 9 of different weights.

[0027] In an embodiment of this utility model, the gravity block 9 includes a weight portion 901. One end of the weight portion 901 is integrally formed with two elastic clamping portions 902. A clamping cavity 903 is formed between the two clamping portions 902 and the weight portion 901. By squeezing the opening between the two clamping portions 902, the diameter of the pull rope 8 can be enlarged, making it easier for the pull rope 8 to enter the clamping cavity 903, thereby achieving the effect of fixing the position.

[0028] In an embodiment of this utility model, a slot 301 is provided on the side wall at the connection between the base plate 3 and the pedal body 1, and a pin 10 is inserted between the pedal body 1 and the slot 301; the plug-in connection method is convenient for assembly and can also be disassembled and used separately, making it flexible in combination.

[0029] Working Principle: This embodiment provides a novel stepper. In use, the user first stands on top of the stepper body 1, then picks up the handles 801 on both sides. Next, the user moves their legs by pushing the stepper body 1, while simultaneously pulling the pull rope 8 to move the movable plate 5 upwards inside the vertical cylinder 4. This compresses the spring 7 between the movable plate 5 and the cylinder cover 402, providing upward resistance. When the user lowers their arms after the movable plate 5 has moved to its final position, the movable plate 5 returns to its original position under the force of the spring 7. Repeating this process achieves an upper body workout. As the plate 5 moves repeatedly, the friction can be reduced by the cooperation of the limiting part 6 and the limiting groove 401. The rolling effect of the large ball bearing 602 and the small ball bearing 603 can reduce the noise generated by the movement and reduce the impact of noise on the mood of the exerciser. In this way, the upper body can be stretched while pedaling. When it is necessary to increase the intensity of the upper body exercise, the weight block 9 can be locked between the two limiting rings 802 to increase the upward pull and further increase the exercise intensity, meeting the needs of people who exercise the whole body. This can enhance the overall structure's effectiveness.

[0030] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
