Description

[Technical Field]

[0001] The present invention relates to an exercise machine that has various muscle training, stretching and massage functions and also has practicality. [Background technology]

[0002] As the population ages, the number of patients suffering from lifestyle-related diseases, cerebral infarction, myocardial infarction, dementia, and other conditions is on the rise. Therefore, exercise is what doctors recommend most. At the end of 2023, the Ministry of Health, Labor, and Welfare recommended "muscle training" for the first time to maintain health. However, a survey showed that approximately 70% of people have no exercise habits. Reasons cited included "it's tiring," "I have a bad back," "I have bad knees," "I don't like exercise," "it's a hassle," "I don't have the time," and "I don't have the money."

[0003] A variety of exercise equipment has been sold to solve these problems, including the hugely popular "Wonder Core Series," which uses spring power to assist abdominal exercises, and Mizuno's Squat Thruly α, which uses gas pressure to assist squats.

[0004] Patent Document 1, which is similar to this project, uses a seesaw mechanism as a chair-type exercise device to primarily perform plantar and dorsiflexion of the ankles. However, it is used for push-ups in Figure 18 and for back stretching in Figure 19. However, this structure does not provide a thick cushion that contacts the abdomen, back, and buttocks, making it unsuitable for practical use. The swing mechanism is also different from this project. Patent Document 2 also uses a seesaw exercise to assist with abdominal exercises (sit-ups), but the rocking mechanism is different from that of this project. Also, although the (02) cushion rubber is 20 mm thick, it has the same width and depth as the (01) deck, and when weight is applied, it will likely come into contact with the hard corners of the (01) deck, making it difficult to implement. Furthermore, according to the drawings, the (01) deck is very thin, raising serious concerns about its strength. In any case, it lacks practicality. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7312339 [Patent Document 2] Patent Publication No. 2007-90005 Summary of the Invention [Problem to be solved by the invention]

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the configurations of the embodiments described below, but includes all specific embodiments that achieve the object of the present invention and are within the scope of the claims.

[0011] The exercise equipment according to the embodiment of the present invention allows users to easily perform muscle training, stretching, and massage at the same time at home, and is practical for everyday use. Figure 1 is a perspective view of the main body. From the top, it is composed of a cushion part 1, a base part 2, and a roller part 3.

[0012] Figure 2 shows four views of the main body (top view, perspective view, front view, and side view). Looking at the top view, there are gently curved top curves 4, which are symmetrical and indented at the top and bottom. This is a design element that evokes a slimming effect, and the indentations do not have to be present. The front view shows a gently indented front curve 5 in the center. This is designed to improve the fit and prevent the body from shifting left or right when the main body cushion part 1 comes into contact with a part of the body during exercise.

[0013] Figure 3 shows the layout of each part of the main body in an easy-to-understand, top-to-bottom order. The cushion section 1 is made of two parts: cushion A6, which is made of a medium-resilience elastic material, and cushion B7, which is made of a high-resilience elastic material. Cushion A6, which comes into direct contact with the body, is made of a material that fits snugly without losing its shape, while cushion B7 reduces the resilience of the hard base section 2, allowing for optimal exercise. Since the cushion section 1 is likely to become dirty from sweat and dirt, it is preferable to attach a removable cover that covers the entire body. This is because a removable cover makes washing easier. As the cushion section 1 has a three-dimensional curved surface and recesses, a stretchable material is preferable for the cover fabric. There is a base cover 8 under the cushion B7. It is preferably made of a strong, hard resin. The reinforcing member 10 sandwiched between the base cover 8 and the base A9 is a square pipe, and is preferably made of a lightweight metal. This is to ensure that it is strong enough to withstand an exerciser's weight of around 100 kg. The reinforcing member 10 is shaped to fit snugly into the base cover 8 and the base A9. The base A9 is also preferably made of a strong resin. However, the base part 2 can be made of a different material as long as strength is ensured. The width and depth of the base part 2 are slightly smaller than those of the cushion part 1. This is to prevent the body from hitting the corners of the base part 2 when weight is applied, allowing for optimal exercise. The roller part 3 is located at the bottom center of the base A9. It is cylindrical, with a diameter of about 7 to 12 cm, slightly smaller than the width of the base part. There are multiple wavy depressions along the circumference, but these depressions can be of other shapes. A foam roller for general myofascial release would be fine, but it is preferable to use one that generates electric vibrations, as this provides a massage effect while exercising. The roller cover 11 is located under the roller part 3. It is preferably made of thick fabric with a non-slip inner lining made of resin or rubber. The roller cover 11 is fixed to the bottom of the base A9, and the roller part 3 can be wrapped around it and secured to the base part 2 and roller part 3 by using double-sided tape or similar at the end. Such foam rollers are widely available and can be substituted with any foam roller with a diameter of approximately 7 to 12 cm. If you already own a foam roller, it would be economical and convenient to purchase only the cushion part 1 and base part 2. The method of joining the base part 2 and roller part 3 can also be different.

[0014] Figure 4 is a diagram for explaining in detail the part where the base part 2 and the roller part 3 are joined. 4A at the top is a perspective view from diagonally below. 4B at the bottom is a close-up view from the front. A roller base 12 and a roller stopper 13 are located on both sides of the center of the bottom edge of the base A9. The roller base 12 is a protrusion with a hemispherical depression that fits the diameter of the roller part 3, and is approximately 1 to 3 cm thick and 3 to 5 cm high. This serves to prevent the roller part 3 from shifting back and forth. The roller stopper 13 located on the outside of the roller base 12 serves to prevent the roller unit 3 from shifting left and right due to vibration if it is electrically powered. It is approximately 0.5 to 1.5 cm thick and 2 to 3 cm high. In the case of an electric roller, there is a hemispherical depression in the center of the roller stopper 13, as most electric rollers have power and mode change buttons in the center of both sides, and the depression is left open to press these buttons. When using a commercially available foam roller as a substitute, there are slight differences in diameter, so a hemispherical cushioning material 14 approximately 5 to 10 mm thick is placed along the left and right width of the roller base 12. This cushioning allows for compatibility with rollers of slightly different diameters. A non-slip material is preferable for the cushioning material 14. Furthermore, since commercially available foam rollers come in different widths, a correction roller stopper 15 with a thin, cushioned thickness of approximately 5 mm and the same shape as the roller stopper 13 can be placed inside the roller stopper 13 to adjust the width. By providing multiple correction roller stoppers, different widths can be accommodated. One side of the correction roller stopper 15 is a sticker, which can be attached and fixed to fit commercially available rollers. Other methods for joining the base portion 2 and roller portion 3 and for adjusting the width of the roller stopper 13 are also acceptable.

[0015] Figure 5 is a diagram illustrating the portion where the cushion section 1 and base section 2 are joined. Female hook-and-loop fasteners 16 are located at the four corners of the bottom of cushion B7 of the cushion section 1, and male hook-and-loop fasteners 17 are located on the top surface of the base cover 8 so as to fit the female hook-and-loop fasteners 16. Each is a regular square, arranged at equal intervals vertically and horizontally, which not only makes the cushion section 1 and base section 2 detachable, but also allows the cushion section 1 to be joined by rotating it 90 degrees when viewed from above, and to be used for other exercises, which will be described later.

[0016] Figure 6 is a diagram explaining how the main body swings. A typical seesaw motion is a swing around a rotation axis installed on the base, but the main body is different; when it rotates, it swings with horizontal movement according to the diameter of the roller part 3. The larger the diameter, the greater the movement distance, and the smaller the diameter, the shorter the movement distance. It has a simple structure and does not require a base compared to a typical seesaw structure, so there are fewer parts, which has the advantage of reducing manufacturing costs and manufacturing processes.

[0017] Figure 7 shows a person lying on their back with the device placed near their waist and doing sit-ups. The shift in center of gravity and see-saw effect make this exercise easy to perform even for those who are not good at it. If the roller unit 3 is an electric roller, turning it on allows for muscle training and a waist massage at the same time, which is convenient. The thick cushion unit 1 and the top curve 5 mentioned above firmly envelop the area in contact, allowing for optimal exercise.

[0018] Figure 8 shows two types of leg raises performed. In both cases, the user is lying on their back with the device placed near the waist and the buttocks raised, allowing for easy leg raises. The upper image shows a knee-to-chest exercise, where the user extends the legs, raises them vertically, and then bends the knees while bringing them towards the chest. The lower image shows a leg raise, where the user extends the legs, raises them vertically, then tilts the legs diagonally and returns them to their original positions. Compared to sit-ups, these exercises put less strain on the lower back and can be easily performed even by the elderly. If the electric roller is turned on, muscle training and a lower back massage can be performed simultaneously.

[0019] Figure 9 shows a person lying face down and doing push-ups with the device resting against their abdomen. The abdomen is supported by the cushion 1, which reduces the strain on the arms, making it easy for even those with weak arms to do push-ups. When the electric roller is turned on, it can simultaneously perform muscle training and abdominal massage (intestinal massage).

[0020] Figure 10 shows two different types of stretching. In both cases, the user is lying on their back with the cushion part 1 placed near the waist. In the top image, the user stretches the waist, chest, and shoulders by extending both arms and leaning back in a cheery pose. In the bottom image, the user stretches the hamstrings by extending the legs and bringing them closer to the face. Unlike forward bending stretches performed on flat ground, there is no need to bend the spine, and this can be done easily by using the weight of the feet. As mentioned above, if the electric roller is turned on, this can be done in parallel with a waist massage.

[0021] Figure 11 shows an example of using the cushion part 1 rotated 90 degrees as viewed from above. The upper figure shows a person sitting on the cushion part 1 and tilting left and right to exercise their sides. The lower figure shows a person lying on their back with their calves placed on the cushion part 1 and tilting left and right to twist their waist. In both cases, if the electric roller is turned on, it is possible to simultaneously massage the area in contact with it.

[0022] Figure 12 shows its practicality. Figure 12A shows it being used as a TV pillow, and Figure 12B shows it being used as a smartphone pillow. The moderate inclination allows for comfortable use without straining the neck when watching a screen. Figure 12C shows the cushion part 1 removed, and Figure 12D shows the removed cushion part 1 being used as a lumbar support for a chair or sofa. In this way, it can be used in a variety of practical ways without having to be stored away, even when you are not doing muscle training or stretching. It is also convenient because you can quickly start exercising whenever you feel like it. [Explanation of symbols]
