Description

Technical fields:

[0001] This invention relates to the field of fitness equipment technology, and in particular to a portable single-leg reverse ejection multi-level adjustable electronic stretching device. Background technology:

[0002] An ancient saying goes, "For every inch the tendons lengthen, ten years can be added to one's life." Chinese folklore has long linked tendons to health and lifespan. Prolonged inactivity easily leads to tendon shortening, which is a root cause of various diseases. The principle lies in the fact that the twelve tendon meridians run the same way as the twelve regular meridians; therefore, where tendons are shortened, the meridians are also blocked, resulting in pain. During stretching, pain in the ankles, knees, and hips indicates tendon shortening in these areas, suggesting corresponding meridian blockage. Stretching makes tendons more flexible, thus "aligning bones and softening tendons allows for the free flow of qi and blood," eliminating or alleviating pain, numbness, and swelling in the waist, knees, limbs, and throughout the body. In traditional folk therapies, stretching the ankle tendons is believed to prevent stiffness, strengthen bones and muscles, and improve blood circulation. The most common way to stretch the ankle tendons is to stretch the toes to the heel at an angle to the horizontal. Chinese patents with publication numbers CN2730422Y and CN213912156U disclose a stretching device. Its disadvantages are: first, it is bulky and inconvenient to carry and use anytime and anywhere; second, both devices involve standing on an inclined pedal with both feet simultaneously, keeping the feet in contact with the pedal and moving synchronously, and the feet and pedal are relatively stationary, which is actually a static stretching method. This method has poor stretching effect, slow blood circulation, and cannot achieve the ideal stretching effect.

[0003] In summary, the aforementioned problems with existing tendon tensioners have become a pressing technical challenge that needs to be addressed within the industry. Summary of the Invention:

[0004] To overcome the shortcomings of existing technologies, this invention provides a portable single-leg reverse ejection multi-level adjustable electronic stretching device, which solves the problems of large size and inconvenience of carrying traditional stretching devices, as well as the problems of poor stretching effect and slow blood circulation.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] Portable single-leg reverse ejection multi-level adjustable electronic stretching device, including:

[0007] A base on which two parallel pins are mounted;

[0008] The upper adjustment pedal is located above the base to support the forefoot. The upper adjustment pedal has a gear adjustment hole at the position corresponding to the pin shaft. The gear adjustment hole cooperates with the pin shaft to adjust the height of the upper adjustment pedal.

[0009] The lower adjustment pedal is located below the base and is connected to the base via an elastic rod assembly. The lower adjustment pedal and the base can rotate freely 360 degrees. The lower adjustment pedal has an elongated hole that cooperates with the elastic rod assembly to adjust the relative length of the lower adjustment pedal to support the heel.

[0010] The upper adjustment pedal is fastened to the top of the base in the shape of a cover. The gear adjustment holes are located on both sides of the upper adjustment pedal. The two ends of each pin are respectively inserted into the corresponding gear adjustment hole. The gear adjustment hole is provided with several adjustment grooves of different heights that cooperate with the pins.

[0011] An electronic timer is installed inside the upper adjustment pedal.

[0012] The upper adjustment pedal is covered with an outer protective sleeve, which is made of soft plastic material.

[0013] The top corner of the upper adjustment pedal has an inclined surface along its length.

[0014] The base is provided with a set screw for tightening and fixing the pin below it.

[0015] The base has a groove along its width that matches the width of the lower adjustment pedal.

[0016] The elastic pull rod assembly includes a screw rod that passes through the inner hole of the base from bottom to top. The screw head at the bottom of the screw rod is located in the elongated hole of the lower adjusting pedal. A nut is threaded to the top of the screw rod, and a spring is provided on the outside of the screw rod between the nut and the base.

[0017] The upper surface of the lower adjustment pedal is provided with anti-slip texture, and one end of the lower adjustment pedal is provided with a stop.

[0018] The base, upper adjustment pedal, and lower adjustment pedal are all made of plastic.

[0019] The present invention adopts the above-described solution and has the following advantages:

[0020] This invention features a clever structural design, small size, and light weight, making it convenient to carry and use anytime, anywhere. It utilizes physical methods for reverse stretching, allowing users to reasonably control the stretching intensity and lead time. It can be used anytime, anywhere. The reverse force uses the body's weight and the legs to provide a natural stretch to the calves and tendons, quickly stimulating blood circulation in the feet and calves. It does not damage the nervous system, muscles, or tendons; instead, it allows the tendons and muscles to quickly get exercise and blood circulation during the stretching process, thus achieving the purpose of stretching.

[0026] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] like Figure 1-4 As shown, the portable single-leg reverse ejection multi-level adjustable electronic stretching device includes:

[0028] Base 1, on which two parallel pins 2 are mounted;

[0029] The upper adjustment pedal 3 is located above the base 1 to support the forefoot. The upper adjustment pedal 3 is provided with a gear adjustment hole 4 at the position corresponding to the pin 2. The gear adjustment hole 4 cooperates with the pin 2 to adjust the height of the upper adjustment pedal 3.

[0030] The lower adjustment pedal 5 is located below the base 1 and is connected to the base 1 via an elastic pull rod assembly. The lower adjustment pedal 5 and the base 1 can rotate freely 360 degrees. The lower adjustment pedal 5 has an elongated hole 6 that cooperates with the elastic pull rod assembly to adjust the relative length of the lower adjustment pedal 5 to support the heel.

[0031] The upper adjusting pedal 3 is fastened to the top of the base 1 in a buckle-like shape. The gear adjustment holes 4 are located on both sides of the upper adjusting pedal 3. The two ends of each pin 2 are respectively inserted into the corresponding gear adjustment hole 4. The gear adjustment hole 4 is provided with several adjustment grooves 7 of different heights that cooperate with the pins 2. The adjustment grooves 7 can be set to three positions: upper, middle, and lower. By moving the upper adjusting pedal 3 up and down and left and right, the pins 2 can be engaged in the adjustment grooves 7 of different heights, thereby adjusting the height of the upper adjusting pedal 3 on the base and achieving different degrees of tension.

[0032] An electronic timer 8 is installed inside the upper adjustment pedal 3. The time can be set and it serves as a timer. When the stretching reaches the predetermined time, an audible reminder will be given.

[0033] The upper adjustment pedal 3 is covered with an outer protective sleeve 9, which can protect the upper adjustment pedal 3 and the electronic timer 8. The outer protective sleeve 9 is made of soft plastic material.

[0034] The upper adjustable pedal 3 has an inclined surface 10 at the top corner along the length direction. The inclined surface 10 cooperates with the forefoot to improve comfort.

[0035] The base 1 has a set screw 11 located below the pin 2 for tightening and fixing the pin 2. The set screw 11 is threadedly connected to a threaded hole in the base 1. By tightening the set screw 11, the pin 2 can be tightened and fixed. Loosening the set screw 11 allows the pin 2 to be removed, thereby allowing the upper adjusting pedal 3 to be removed for cleaning. A countersunk hole is made at the bottom of the base 1 at the position of the nut at the bottom of the set screw 11, so that the nut is located in the countersunk hole to keep the bottom of the base 1 flush.

[0036] The base 1 has a slot 12 at its bottom along the width direction that matches the width of the lower adjustment pedal 5.

[0037] The elastic pull rod assembly includes a screw 13 that passes through the inner through hole of the base 1 from bottom to top. The screw head 14 at the bottom of the screw 13 is located in the elongated hole 6 of the lower adjusting pedal 5. A groove can be provided at the bottom of the elongated hole 6 to keep the screw head 14 in the groove and keep the bottom of the lower adjusting pedal 5 flush. A nut 15 is threaded to the top of the screw 13. A spring 16 is provided on the outside of the screw 13 between the nut 15 and the base 1. When the lower adjusting pedal 5 is moved downward, the spring 16 is compressed, and the lower adjusting pedal 5 and the base 1 can rotate freely 360 degrees. When the lower adjusting pedal 5 is rotated to be perpendicular to the base 1, the spring 16 returns to its original position and drives the lower adjusting pedal 5 to move upward, so that the lower adjusting pedal 5 is just locked into the slot 12 at the bottom of the base 1 to keep the bottom of the base 1 flush. At this time, the position of the screw head 14 at the bottom of the screw 13 in the elongated hole 6 can be adjusted so that the relative length of the lower adjusting pedal 5 and the base 1 matches the size of the foot.

[0038] The upper surface of the lower adjustment pedal 5 is provided with anti-slip texture 17 to prevent slipping. One end of the lower adjustment pedal 5 is provided with a stop 18 to block the heel.

[0039] The base 1, upper adjustment pedal 3, and lower adjustment pedal 5 are all made of plastic, making them lightweight and easy to carry.

[0040] Working principle:

[0041] In use, first move the upper adjusting pedal 3 so that the pin 2 is engaged in the adjusting groove 7 at the appropriate height, thus completing the height adjustment; then move the lower adjusting pedal 5 downwards, rotating it to a position perpendicular to the base 1. The spring 16 returns to its original position, causing the lower adjusting pedal 5 to move upwards, so that it fits perfectly into the groove 12 at the bottom of the base 1, keeping the bottom of the base 1 level. Adjust the relative length between the lower adjusting pedal 5 and the base 1 according to the size of your foot. Once the adjustment is complete, you can then begin stretching. When stretching, first prepare by placing the ball of one foot on the upper adjusting pedal 3 and the heel on the lower adjusting pedal 5, which is blocked by the stop 18. Keep the corresponding lower leg and thigh straight. Step forward with the other foot a suitable distance and place it on the ground for support. You can hold onto other objects for balance. Move the heel on the lower adjusting pedal 5 up and down like a spring, achieving the stretching purpose. After stretching one leg, you can switch to the other leg. This invention utilizes a physical method for reverse stretching, allowing for reasonable control of the stretching intensity and lead time. It can be performed anytime, anywhere. The reverse force uses the body's weight and legs to provide a natural stretch to the calves and tendons, quickly stimulating blood flow in the feet and calves, acting like a compressor to improve blood circulation in the extremities. This process does not damage the nervous system, muscles, or tendons; instead, it promotes rapid movement and blood circulation, achieving the desired stretching effect. The heel, positioned on the lower adjustable pedal, moves up and down like a spring, further stimulating blood flow to the extremities, providing a compression effect. Regular practice improves blood supply and synovial membrane function in the knees. When stretching barefoot, the upper adjustable pedal can be adjusted to its lowest position. When wearing shoes, the height of the upper adjustable pedal can be adjusted freely for personal comfort. When you start stretching, try not to do too many repetitions. Proceed gradually and adjust the number of repetitions according to your own condition. You can start with 50 repetitions for each leg as a set, and then gradually increase the number of repetitions based on the effect of the stretching, until your knee joints feel warm.

[0042] The above specific embodiments should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, any alternative improvements or modifications made to the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0043] Any aspects of this invention not described in detail are well-known to those skilled in the art.
