Abstract

<P>PROBLEM TO BE SOLVED: To provide an instrument for training abdominal muscles, which is operated with less back muscle strength compared with a conventional method with the use of the bearing type seesaw mechanism of the instrument when doing exercises since it is difficult for a person with feeble muscles, especially, an aged person, a woman, or a child, to perform training as the large back muscle strength is required in training the abdominal muscles, etc., and which is lightweight and excellently portable without neither requiring a large floor area nor damaging a floor or a carpet, is inexpensive in price and mailing cost, and is suitable for a mail-order service. <P>SOLUTION: The abdominal part of a user is put on a top board (01) with a cushion material (02) stuck thereon. The user easily sits up with the back muscle strength being extremely smaller than that required in the conventional method even when the user is an oriental person with a longer body through the use of the bearing type seesaw mechanism which includes: a top board beam (10); a hinge axis (06); axis positioning brackets (05), (08); a snap ring or color metallic material (07); a base board beam (11); a base board (03); and a cushion material (04). Thus, even the person with the feeble muscles easily and repetitively trains the abdominal muscles, etc., without requiring much strength and obtains a desired effect. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

It is in the technical field of instruments (health exercise equipment).
The present invention is an instrument that an individual uses to improve the health of the person at home, in a gymnasium, or outdoors. It can also be used for physical training for large numbers of people at schools.

Welfare medical science and physical education are background technologies.
Traditional exercises for abdominal and back muscles were to lay the body on a floor or a slanted bed and to tilt the upper body, but this exercise itself was the weight of the upper body and especially the neck. As a result, it takes a lot of physical strength. If there is no physical strength, nobody can do it, and few people can continue effective exercise for a long time.
Therefore, the desire to solve this problem and make it easy for anyone to repeat for a long time has arisen.
JP, 10-230022, A Training management system in abdominal muscle exercise. JP, 2000-135298, A Training mat. JP, 10-277177, A Two-stage book type portable health device. JP, 2000-024136, A Device which isolates and trains an abdominal muscle. The device of Document 1 is widely used in public GYMs, etc. However, as described above, it is necessary to use abdominal muscles for abdominal exercises. It is a product that cannot be used by the elderly, girls, and children who are particularly weak. The present invention has been improved so that even a weak general person can easily perform abdominal exercises. The usage method may be used on the instrument of Document 1 or may be used alone. Anyone can easily and repeatedly exercise with much less power than conventional ones, and the effect is more than several times.

Although it is a well-known fact that it is necessary to train the abdominal and back muscles in order to make the body healthy, it has been a difficult task especially for those who are weak.
Therefore, by using a simple instrument to raise the upper body, the number of people who train the abdominal muscles and back muscles will increase, so that even weak people can easily do so, a society of healthy people will gradually be created, and the national society will bear I came to think that it was a problem that led to reduction of medical expenses.
This problem is also a social problem that can be widely applied to both men and women of all ages.
In addition, as a usage method, there are a method of using this instrument directly and a method of using it in addition to conventional equipment.

Means to solve the problem

What is a simple instrument that solves the problem? In short, the deck (01) on which the user's body is placed and the base plate (03) that supports the entire body with a device having the function of a small seesaw. The main shaft (05), the bearing structure (06.07), and the soft thick rubber plate that becomes the cushion (02.04) are formed by connecting and supporting the two.

First, a sheet (09) is laid on the floor, and the instrument is placed on the sheet (09), with the long side (A) of the deck (01) facing the leg. Naturally, the short side (B) is in the direction of the back. Next, sit down on the sheet so that the buttocks touch the long end of the instrument.
However, people who are as long as Westerners can place their hips on the long side (B) of the cushion rubber (02) on the deck, but the fulcrum must not be exceeded. In this state, place your body on your back on the instrument.
In this case, the back touches the cushion rubber (02) on the deck, and when it is lowered further, the hips and legs are naturally lifted. In this case, it is necessary to support the neck by hand for safety. The back may be lowered until it reaches the seat (09). If the leg is raised high in the air, it alone will give weight to the abdominal muscles and exercise. The Western method with B / A of 1: 1 gives the inertia when swinging down the legs. In the present invention, A: B is set to a predetermined ratio, and B is set to a predetermined length. Then, the upper part of the upper body can be easily raised without requiring more force than the conventional method because the part B automatically pushes up the back in a see-through manner according to the weight of the lower body.
In this case, (1) the bearing structure causing the seesaw motion, (2) the ratio of A: B indicating the position of the fulcrum, and (3) the dimension of B effective for raising the back are solved. It is to be a specific means to do.

The invention's effect

With the following three types of devices, the abdominal muscles, back muscles, and other muscles can be trained with less force than conventional methods and instruments.
In addition, if performed lightly, it also has the effect of promoting blood circulation, and is effective in promoting health for elderly people who are weak.

The bearing structure that supports the seesaw movement of this instrument mainly supports the weight of the user on the deck and the gravity in the Z direction due to the movement, and ensures positioning in the X and Y directions when performing the seesaw movement. I can do it. However, since the contact area with the shaft is an arc, it is large for the shaft diameter, the load per unit area is small, light movement is possible, and wear is difficult.
In particular, compared to knife edge type seesaw exercise equipment, the equipment itself is not damaged and the floor and rugs are not damaged, so that it can last for a long time.

How to determine the position of the fulcrum on the deck of the instrument is particularly easy for non-powerful people to quietly raise the upper body by simply raising the legs and moving the upper body slightly downward without using the reaction. It has a structure that can do things. The structures in this section and the following section are suitable for orientals who have many body lengths.
The setting value of the fulcrum is A: B between 1: 0.82 and 0.58, where A is the length from the end of the deck leg to the fulcrum and B is the length of the head. And
It should be noted that the value of B can be slightly increased when the couple due to the inertia of the leg is used together.

When the upper body is raised, the length of the part B that hits the back is made in the range of 70mm + 25mm, -15mm.
If this number is too small, the lion's power to push up the back is reduced. Also, if this number is large, the user's power is required by that ratio.

Detailed description of the instrument structure of the present invention

The details of the sectional view from the front of the present invention in FIG. 1 will be described.
(01) is a deck with a soft cushion rubber (02) affixed to the top, and the user's body can be placed on it with a soft touch.
(03) is a base plate, and a thin rubber plate (04) is attached to the bottom to protect the floor. A sheet (09) is placed under the base plate so as not to contaminate the user's clothes. A lower bearing (08) is mounted on the base plate (03) and supports the upper bearing (05) via a shaft (06). The upper bearing (05) is attached to the lower surface of the deck (01). (07) is a snap ring that prevents the shaft (06) from being displaced in the axial direction and coming off the bearing (05,08).
The two upper and lower beam portions (10, 11) are in cylindrical contact with the upper and lower surfaces of the shaft, respectively, and support the weight in the Z direction applied to the bearing from the deck by the entire base plate.

  2a and 2b are side views. a shows a component structure, b shows the ratio of a fulcrum.

  FIG. 3 is an enlarged sectional view of the bearing portion.

  FIG. 4 is a plan view seen from above.

5 to 14 show the posture and usage method of the user, respectively.
5 and 6 show how to use the device for the elderly and the like who are weak in the standard use state.
First, as shown in FIG. 5A, a leg is thrown on a sheet laid on the floor and sits down. At this time, the position where the end of the long side of the device hits the buttocks is taken as a base point. Next, lie down in the direction of the arrow and tilt your body back to the position shown in FIG. Next, when the weight of the lower body is hung on the long side of the device, the long side is lowered to the original position in Fig. 5B, and the short side pushes up the back, so the upper body does not require a great force and the initial posture You can return to Lee. In other words, by using this instrument, it is possible to perform repetitive exercises to train the abdominal muscles and back muscles even for the weak elderly, girls and children.
7 and 8 require considerably more physical strength than the previous item when the device is used for young people. When placing the body on the instrument, place the hips on the top of the deck as shown in Fig. 7D. However, it should be on the long side of the fulcrum and not on the short side. The degree may be selected according to the individual body shape. First, as shown in FIG. 7E, when the body is gently tilted backward, the instrument is also tilted backward and the lower half of the body is lifted as shown in FIG. In this case, if the foot is raised to the position shown in FIG. 8, the weight of the lower body is applied to the abdominal muscles and the like, and the effect of training can be obtained by itself.
When raising the foot, it acts as a couple with a reaction when it is lowered, and the upper body can be raised to the position of E, D. The degree can be determined by the individual according to the body shape. The use of this method requires considerable physical strength, so it can be said that it is a training method for young people.
FIG. 9 and FIG. 10 show how to use this device to promote light blood circulation for a person who lacks exercise.
So-called sitting people who are all day-to-day with their computers, office work and reading books, can't afford to exercise until they go out. So, if you place this instrument on a chair and sit on it deeply, and repeatedly swinging your body back and forth and up and down as shown in the figure, it will result in light abdominal and psoas muscles and blood circulation. Because it can promote and lower blood pressure, it is better to use this device for about 5 minutes in one hour and also to change the mood. This method also works on the middle muscles and is effective in preventing and recovering back pain. In this case, do not use a swivel chair with increased slack because it is dangerous. Use a solid dining chair as much as possible.
11 and 12 show the abdominal muscles and back muscles in a state where the blood circulation can be promoted for an elderly person who fell asleep with this instrument and can be performed while lying down.
FIG. 11 shows the case of abdominal muscle training. It is necessary to be careful not to hurt other parts of the body by placing a waist on the device and putting a cushion on the leg or back.
FIG. 12 shows the case of spine training. Place the equipment under your back and wear a cushion or pillow under your waist or head so that it does not overwhelm other parts of your body.
If you cannot exercise yourself, you can do it with the help of a helper.
However, in this case, the doctor's guidance is required for implementation. Care must be taken especially when it is performed for a long time.
FIG. 13 and FIG. 14 show an application example of the present invention in which the abdominal and spine training functions are applied to a Japanese-style seat chair.
In the seesaw bearing structure, it has the same principle and structure as the instrument shown in FIGS. FIG. 13 shows a state in which the use is started. First, the instrument is placed on the sheet so that the back of the body reaches the backrest. Next, while holding both hands on the handles on both sides and supporting the body so that it does not fall down, as shown in FIG. It is almost horizontal and can be tilted down to about minus 5 degrees. Next, raise your body to the original posture. In this case, you can use legs and hips. Therefore, according to this instrument, the abdominal muscles, back muscles, psoas major muscles, quadriceps muscles, knee ligaments and the like can be trained.
The feature of this device is that the upper body and head are rested to stabilize and prevent danger, but the greatest feature is that training for the less powerful elderly and girls can be done safely and easily. .
In addition, because it is the same height as the seat chair, there is a distance to the ceiling even if it is operated in a Japanese-style room.

(Social effects due to the widespread use of this device) There is now a remarkable socialization of longevity in Japan, and it is about to exceed the average age of 80. I have heard that the population over 65 years old will already exceed 20%, and will reach 25% in five years.
In this area, the increase in medical and nursing care benefits for the elderly has become a problem.
As a drastic measure, it is good if the elderly are healthy, and if they do not rely on the doctor's medicine as they do in the past, they can nurture themselves and become able to develop a healthy and long-lived society if they work for physical and mental training. It should be able to contribute to the improvement of Japan's economy and social momentum.
Due to its widespread use, this instrument opens the way for inferior elderly people who have not traditionally exercised and their reserve army to easily train themselves with their own power. I think that it is an instrument that can be expected to be effective as an effective means.

(Industrial applicability 2 Economic effects of the widespread use of this device) This device is a personal health promotion device, and also when used as a group in GYM or schools, in terms of occupied area and price. Since the cost can be saved, it is expected that the economic effect will be remarkable if combined.
In addition, since there are times when waste is regarded as a problem in terms of time and money to go to GYM, taking advantage of the features of this device that can be used even in small places, training is easy and economical at home and in parks, etc. The feature of being able to do so is certainly attracting attention, and it is expected that the spread era will be realized sooner and later as a single unit in the family and utilized by the whole family according to their physical condition.
In fact, it is a product that can exhibit features that are superior in function and price compared to imported products.
(Market status of similar patents related to this device)

  About similar patents Currently, there are no domestically found instruments that are mechanically similar to this instrument. There is a device that is slightly similar to the imported product, but it is based on a completely different principle in terms of mechanism. However, it looks similar in appearance, so I will add a commentary so that there is no misunderstanding.

  About Japanese patents on foreign products The product name is “Abu Wedge”. It looks like a USA product. It is a mail-order product that has been advertised on TV early in the morning. However, the manufacturer name is unknown. I searched domestic and foreign patents, but I couldn't find any. So I decided to add a comment here.

Features of mechanical structure. While performing a seesaw movement is similar to our instrument, its mechanism and usage is completely different from the present invention. The main point is the mechanism that makes a seesaw movement with a kind of wedge, as the name suggests, and the usage also uses the couple of inertia that swings and builds the lower body, which is different from the bearing structure of our principle. ing. For this reason, the wedge is easily worn out by the concentrated load, easily damages the floor and the rug, and there is a fear of danger when it is damaged. There is no fear of damage due to damage to our structure, and gravity does not damage the floor or rug because the base plate receives on average.
Appearance shape is also higher and narrower than our equipment. The place where the body is placed is almost in the center, and it can be said that this is a position for Westerners with long legs. As a result of numerous experiments, we have set a reasonable amount of deviation according to the shape of the Oriental with short legs. In addition, we can push up the back automatically and quietly using our own weight, so we have the advantage of not requiring great force. The other one needs a lot of power. However, it is unsuitable for the powerless person, so it can be said that it is not suitable for the elderly.
The harder deck is like a hard object like ABS. Since we are using soft rubber that is gentle on the body, it is hard to get tired because there is no reason to hit the body.
The previous manufacturing method can be applied only to mass production, but our manufacturing method can be appropriately adapted to both small quantity and mass production. This can be started with less initial investment, so the structure of our equipment is a decisive advantage for entrepreneurs.
