Description

[Technical Field]

[0001] The present invention relates to a foot massage device which is expected to play a major role in maintaining good health. [Background technology]

[0002] Massaging the feet has the effect of promoting blood flow and flushing out waste products. Since blood vessels and lymph nodes are concentrated in the calves and behind the knees, massaging these areas is said to be particularly effective if the muscles in your legs have lost flexibility and feel stiff. A variety of devices are available for such foot massage. There are various types depending on the purpose and method of use, such as massage, health methods, and muscle training. The targets are the soles of the feet, calves, thighs, etc. In particular, the calves are said to be the second heart, and massaging the calves is said to have benefits such as promoting blood circulation, detoxifying the body, improving basal metabolism, improving the autonomic nervous system, and boosting immunity. In order to achieve these effects, various devices and equipment using EMS, heat, electricity, and air pressure have been devised. For example, massages using various devices that use EMS, heat, electricity, and air pressure. Or the massage effect of exercise using assistive devices.

[0003] However, most of these devices target individual parts of the body, such as the soles of the feet, calves, or thighs, and some require a power source (energy source). Although there are devices such as chair massagers that can massage the entire foot, it is not easy for an average household to have such a chair massager because it is expensive and takes up a lot of space.

[0004] Patent Publication No. 2020-174929 Patent No. 7395781 Patent No. 7395781 (P7395781) Summary of the Invention [Problem to be solved by the invention]

[0005] There are various types of massage equipment that massage various parts of the feet, but there are few compact, inexpensive massage machines that can massage the entire foot. Some say that fidgeting is good for your health, especially when it comes to your entire leg. The present invention provides a compact and inexpensive massager that can simultaneously massage the entire foot. [Means for solving the problem]

[0006] The action of dangling the feet can also be considered as a kind of link mechanism, involving the relationship and movement between the toes and ankle joints, the foot and knee joints, and the foot and hip joints. The present invention provides The foot, which is likened to this link mechanism, is a kind of crank consisting of a pedal, a crank, and a crankshaft. By arranging it along the mechanism, it performs a series of movements and effects linked to the movement of the foot, aiming to massage the entire foot. A familiar example is the pedals, cranks, and crankshaft of a bicycle; an equivalent product can be obtained by shortening the crankshaft as much as possible and providing a desired angle between the two cranks. The user places the back of their knee joint on the crank axis of the L-shaped angle of the crank mechanism, uses their own muscles to lift the leg from the knee joint, and when they release the force, the muscles relax, and the force of free fall (kinetic energy) due to the weight of the foot causes the calf to hit the crank mechanism, and a moment with the knee joint as the fulcrum is transmitted to the crank mechanism. The crank mechanism swings like a pendulum, and the moment is transmitted to the other end via the crank, pushing against the thigh. When you lift your leg further, the crank mechanism is released and swings like a pendulum, relieving the strain on your calves and thighs. In this way, the cycle of using and relaxing the muscles to lift the leg, and then massaging the calf, back of the knee joint, and thigh muscles as the leg falls freely; in other words, the repeated cycle of using and relaxing the muscles and massaging them creates a massage effect on the leg muscles. You can expect a kind of acupressure effect on the back of your knee joint, which supports your leg. The angle of the L-shape is 90 degrees, but is not limited to this. The massage machine is usually provided with such crank mechanisms for both the left and right feet. [Effects of the Invention]

[0007] The leg-hanging massage machine of the present invention uses the visa joint as a fulcrum while holding the visa joint with the pad (B) 8. Using the user's own leg muscles Lift it up and release the pressure. The muscles relax Leg weight The force of free fall (kinetic energy) causes the calf to push against pad (A) 7. Pad (A) 7 presses the calf, and at the same time Pad (C) 9 presses the thigh through L-angle 5. The pad (B) 8 is expected to have a kind of acupressure effect on the back of the knee joint supported by the pad. More indirectly,When the calf touches Pad (A) 7, it is expected that the ankle will also move flexibly via the ankle joint. Pad B is for the visor joint, Pad (A) 7 for the calf and ankle, and Pad (C) 9 for the thigh. Massage it. Another way to express this is that swinging your feet is massaging the entire foot. The user can do this at will with both legs simultaneously or alternately, and can adjust the strength as well. Because it uses the weight of the feet, no driving source (energy source) is required, and the load on the body is small. It can be used while sitting on the floor or on a chair. The definition of massage is broad and includes rubbing, kneading, pressing, tapping, etc., but the present invention is different from relaxation and is a relatively active kneading technique that has a major aspect of promoting blood circulation and metabolism. However, since it does not involve a full-body movement, but rather involves lifting using the user's own leg muscles, relaxing the muscles by relaxing them, and using the free-fall force (kinetic energy) of the leg's own weight to massage, it puts less strain on the body and uses less physical strength, so it can be expected to be used habitually by a wide range of age groups, including the elderly. As described above, the present invention provides an inexpensive, compact, and excellent massage machine and massage method that can be widely used in ordinary homes, and has potential as a wide range of health equipment, including applications such as sports massage. Furthermore, massage equipment is considered to be a controlled medical device from a safety perspective. However, apart from medical applications, the present invention does not require a specific energy source such as a power source, so there is little risk of breakdowns, unexpected malfunctions, or handling problems caused by the energy source. This high level of safety can be said to be one of the advantages of the present invention. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] The present invention is an L-angle crank 1 and supporting it base It consists of: L-angle crank 1 has a bearing (A) 6 in the center. The base is an L-shaped L-angle crank Engage with 1 crankshaft 12 is held horizontally at a certain height. L-angle crank 1 consists of an L-angle 5, pad A 7, pad B 8, pad (C) 9, and bearing (A) 6. Pads (A) 7, pads (B) 8, and pads (C) 9 are arranged on the L-shaped angle 5 at the portions that come into contact with the feet, and a bearing (A) 6 is provided. Alternatively, the pad A7, the pad B8, and the pad (C)9 may be molded integrally with the L-angle 5. Place both feet on the L-angle 5, and align them using pad (B) 8 behind the knee joint, pad (A) 7 on the calf, and pad (C) 9 on the thigh as a guide. By doing this, the L-angle movement is similar to the movement of the knee joint. crank 1 swings. Generally, it is desirable that the materials of the L-angle crank 1 be lightweight materials such as resin and wood, but there are no restrictions. Ball bearings are generally assumed, but plain bearings are also sufficient. The basic structure consists of the following three components: 1. L-angle crank 1 and base (A) 2. 2. L-angle crank 1 and base (B) 3. 3. L-angle crank 1 and base (C) 4.

[0010] 1. L angle crank The minimum configuration of the leg-hanging massage machine is 1 and base (A) 2.

[0011] 2. L-angle crank 1 and base (B) 3 in is L angle crank 1 teeth It absorbs shocks caused by overloads and operates flexibly. The holding part of the arm 13 is provided with a bearing (B) / Rotation axis In addition to 14, a spring having a function of restoring the load, such as a torsion spring 15, is incorporated, and a stopper 16 that stops at a fixed position is provided, thereby absorbing shocks in the event of an overload and providing flexible support. A torsion spring 15 (torsion spring) is a coil spring that receives a torsional moment around the central axis of the coil. When a moment is applied to the spring, bending stress is generated in the wire, and a reaction force is generated that tries to return this stress to its original position. There are various springs that have the same function as the torsion spring 15, so the torsion spring 15 is not limited to this. This creates arm 13 with an automatic rebound function. It absorbs shock moderately in the event of overload, and you can expect a moderate massage effect.

[0012] 3. L-angle crank The method using 1 and base (C) 4 is L angle crank 1 is supported by an upright stand 17. Furthermore, by incorporating coil spring 18, L angle crank As with the method using 1 and base (B) 3, it provides moderate shock resistance against overload. but absorption And, A moderate massage effect can be expected. The above is intended for general use, but if one is to lie down on a bed, for example, it is desirable that the height be low. Furthermore, if rehabilitation purposes are envisaged while the user is lying down, it will be difficult to raise the legs too high. In such cases, the angle of the L-shape can be set to 180 degrees, i.e. flat, to lower the height of the crank mechanism, and the height of the pads that come into contact with the calf, the back of the knee joint, and the thigh can be adjusted to the desired height, with only the pad located behind the knee joint being higher than the other pads, allowing you to achieve the desired result. [Example]

[0013] Figure 1 shows the L-angle crank The basic form of the foot-hanging massage machine is composed of 1 and base (A) 2. It can be used on the floor, or by placing it on a chair and fixing the plate 10 to the chair with a band, it can be used while sitting on the chair stably. [Example]

[0014] Figure 2 shows an example of a leg-hanging massage machine in which the angle of the L-shape in the example shown in Figure 1 is changed to 180 degrees and made flat, thereby lowering the height of the crank mechanism and making the pad corresponding to the back of the knee joint higher than the other pads. [Example]

[0015] Figure 3 shows: Example 1 crankshaft 12 is a pair of independent L-angles crank Held by 1, crankshaft The other end of the arm 13 supporting the bearing 12 is attached to the bearing (B) / Rotation axis 14 is a leg massager that is held by an L-angle crank It absorbs shocks and operates flexibly in the event of overload on 1. [Example]

[0016] Figure 4 shows: L-angle crank The method using 1 and base (C) 4 is L angle crank 1 is supported by an upright stand 17. By incorporating a spring, it can absorb shocks in the event of overload and operate flexibly. If you lower the stand, you can use it on the floor, or if you raise it, you can use it while sitting on a chair. Even if you sit on a chair, you can just change the height of the Plate 10, so it can remain on the floor. In addition, Examples 1, 2, 3, 4 Generally, it is assumed that the left and right legs are performed simultaneously or alternately, but one L-angle crank It is also possible to use one foot on each of the base and the footrest. In addition, although it is not essential in this embodiment and is therefore omitted, an L-angle crank 1. The comfortable height varies from person to person, so it is desirable to have a height adjustment function. [Industrial Applicability]

[0017] The swinging massage machine of the present invention can massage the entire foot with an inexpensive and compact means, This is a highly safe massager suitable for a wide range of age groups, fields, and applications, including the elderly. [Explanation of symbols]
