Description

  The present invention relates to a stretch chair suitable mainly for stretching and shaping up the stomach.

  In recent years, interest in health and beauty has increased. In particular, there is a strong interest in shaping the waist in beauty, and there are many demands for taking the side meat and getting the ideal proportions. For this reason, a number of devices have been proposed for effectively improving the shape of the stomach.

For example, there are devices that stretch the side of the stomach by forcibly rotating the upper body or assisting the rotation, and devices that stretch the side of the stomach by supporting the exercise of stretching the stomach.

In addition to that, there is a growing interest in training deep muscles to increase basal metabolism and improve blood circulation. Deep muscles are difficult to train with general movements. One way to train deep muscles is to balance the body, such as balance balls and shoes with round bottoms.

  Thus, in order to train the side of the stomach comprehensively, stretching of the side of the stomach is required, stretching in the vertical direction, and exercise of deep muscles near the side of the stomach. However, the conventional exercise assisting devices must be performed with different devices, which is cumbersome, time consuming and expensive. For this reason, there has been a demand for an instrument that simultaneously performs the above-described exercises in order to eliminate these inconveniences.

Further, as an invention for stretching the armpit, a stretch chair (see Patent Document 1) that stretches the waist, flank, and shoulders at the same time has been proposed and is a known technique.

However, in the stretch chair of Patent Document 1, by performing a stretching exercise of twisting the waist, the movement is transmitted from the seat to the armrest, and the armpit and shoulder can also be indirectly stretched. Stretching and shaping up with emphasis, has not yet solved the problem,

  In addition, a chair (see Patent Document 2) is proposed in which the upper body is rotated horizontally while holding a handle arranged on the backrest, and a seat seated with a gear or the like is rotated in the reverse direction (see Patent Document 2). It has become.

However, the stretch chair of Patent Document 2 is a chair that assists in the twist exercise, which is one of the stretch exercises on the side of the abdomen, and only the superficial muscles are trained, and the deep muscles are muscles that can be trained by balancing. The problem of stretching and shaping the side of the stomach has not been solved.

In order to solve these problems, the present inventor focuses on a method of performing stretching and balance exercise at the same time, and proposes a “flank stretch chair”.

Patent Application Publication 2011-36454 Utility model registration No.3051291

In view of the above problems, the present invention provides a backrest that freely rotates while supporting the user's back, a handle portion installed above both ends on the rear side of the seating portion, and a clockwise direction in a front view or a rear view. Alternatively, it is intended to provide a side abdominal stretch chair that effectively trains the abdomen by a seating portion that can freely rotate in a counterclockwise direction.

The side abdominal stretch chair according to the present invention is a chair for intensively stretching the side of the abdomen, a base portion supported by a fixed leg portion, a seating portion in which the left and right of the seat surface rotate up and down, and a user A back support part that freely rotates while supporting the back of the seat, and the back support part is installed on the rear side of the seating part, and the handle parts at both ends protrude in the left-right direction, respectively. It is disposed, has a flat or substantially flat back support surface, is pivotally supported by the base part, and takes a back support part movable means that can be rotated clockwise or counterclockwise in an upward view or a downward view, Furthermore, the seating part is installed on the upper part of the base part, and is pivotally supported on the base part by a support part provided on the bottom surface, and can freely rotate in the clockwise direction or the counterclockwise direction in a front view or a rear view. Use a means to move the seat.

Further, the present invention provides a means in which the backrest portion is pivotally supported on the base portion at a position that is offset within a range of 20 mm to 150 mm rearward (more desirably 50 mm to 100 mm) from the center position of the backrest surface. take.

Moreover, this invention takes the means by which the said flank stretch chair arrange | positions either an elastic member, a damper, or these combination between the said base part and the said seat part.

Further, in the present invention, the flank stretch chair is configured such that two disks are rotatably arranged on the bottom surface of the noble base part, and at least one protrusion is arranged on each of the disks. The interlocking plate portion adopts a means in which the rotation amount is regulated by the protrusion.

According to the side abdominal stretch chair according to the present invention, by the movement of the muscles of the abdomen to keep the seating part horizontal, the horizontal rotation stretch by the upper body along the rotation of the backrest, the vertical and horizontal directions of the side of the stomach Stretching is possible in a short time, improving the user's stretching efficiency, and with the back muscles stretched, the posture improves, and the left and right muscle strength balance and body shape left and right balance Demonstrate the excellent effect of getting better.

In addition, with conventional health equipment and exercise machines, there is no indication as to how much the twist angle of the waist can be twisted at present when performing twist exercise or stretching. However, according to the flank stretch chair according to the present invention, since the handle portion protrudes from the backrest portion in the horizontal direction, the upper body is further twisted by the angle at which the waist can be twisted by the muscle strength around the waist and the force of the arm. It is possible to visually recognize the stretching angle, strength training effect, left and right muscle attachment methods, uneven ligament stiffness, etc. Demonstrate. Further, since the stretch is assisted by the force of both arms, the user can easily grasp the stretch amount even by the movement of the arm, and a sufficient stretch amount can be ensured for the assist by the arm.

Furthermore, according to the flank stretch chair according to the present invention, since the seating surface is pivotally supported at the center of the bottom, the left and right are freely swung up and down, so that the user can keep the level even in the state of twisting the waist. When trying to keep it, the flank stretches unconsciously, so that the stretch effect and muscular strength can be improved more than consciousness.

  The flank stretch chair according to the present invention is characterized by effectively stretching the side of the abdomen in a short time. Embodiments will be described below with reference to the drawings. In the description, when there is no particular limitation, it will be described as left and right and up and down as viewed from the seated user. The overall shape of the flank stretch chair 100 and the shape of each part shown in the present embodiment are not limited to the embodiments described below, and are within the scope of the technical idea of the present invention, that is, the same action. It can change within the range of the shape and dimension which can exhibit an effect.

  The present invention will be described with reference to FIGS. FIG. 1 shows an overall perspective view of the present invention. FIG. 2 shows the same three-plane view, where (a) is a top view, (b) is a front view, and (c) is a side view.

The present invention has a structure in which two movable parts are added to a normal chair. The backrest unit 1 is used to stabilize the sitting posture by pressing the back of the user when sitting, as in a normal chair. The position of the backrest 1 is preferably a position that holds the vicinity of the hips of the user who is seated. This is because the rotation of the upper body should be assisted at a position close to the stomach in order to make the rotation of the upper body larger at the stomach. A handle support portion (left) 3 and a handle support portion (right) 5 are extended at both ends of the back support portion 1, and the handle support portion (left) 3 and the handle support portion (right) 5 are left and right from the back support portion 1. Are provided so as to extend in the protruding direction. A handle part (left) 2 and a handle part (right) 4 are installed at the tips of the handle support part (left) 3 and the handle support part (right) 5. The handle part (left) 2 and the handle part (right) 4 have recesses 202 and 402 for placing the thumb and recesses 201 and 401 for writing four fingers other than the thumb, so that the user can easily grip the correct way. ing. Moreover, it is desirable to provide the arrangement so as to fit in a shape of gripping the palm up and wrapping from below. The handle part (left) 2 and the handle part (right) 4 have handle stop parts 203 and 403. The back support part 1 serves as a support when the user 15 slides his hand. It can be rotated.

The seating part 9 is a part where the user 15 sits like a normal chair. The seat portion 9 and the base portion 10 that supports the seat portion 9 are separated from each other, and are joined by a shaft portion 11 at a central portion with respect to the left and right of the seat portion. The shaft portion 11 is a shaft for rotating the seat portion 9 while supporting it. It should be a material that has sufficient strength with respect to the weight of the user 15 and can rotate smoothly, and iron, aluminum, brass, etc. are desirable. The seating side bearing portion 12 and the base side bearing portion 13 are portions for rotating the seating portion 9 together with the shaft portion 11. It is desirable that the seating side bearing portion 12 and the base side bearing portion 13 have a structure in which the shaft smoothly rotates by a bearing structure or a seal structure. The shaft portion 11 is rotatably fixed to the base portion 10 by a base side bearing portion 13 and is rotatably fixed to the seating portion 9 by a seating side bearing portion 12. Unlike a normal chair, since it is fixed only at the center with respect to the left and right, if the user 15 sits unconsciously, the seat will tilt to the left or right, and naturally the body also tilts in that direction. Therefore, the user 15 sits while keeping his / her balance by keeping his / her waist in order to keep the seating body horizontal.

  Cushion rubbers 901 corresponding to the base portion 10 are arranged at the four corners on the bottom surface of the seat portion 9 when the seat portion 9 rotates to the maximum extent. The base portion 10 is supported by four fixed leg portions 14. Leg rubber is attached to the bottom of the fixed leg portion 14. The leg may be a fixed leg or a caster as shown. However, if the chair moves during stretching, it will become unstable when the body is rotated, so it is desirable that the caster has a lock.

The rotating structure of the backrest 1 will be described along FIGS. 2 (a) and 2 (c). A back support rotation unit 6 is fixed to the back surface of the back support unit 1, and the back support rotation unit 6 is rotatably fixed to the back support support unit 7 by a back support rotation unit stop 601. The back support portion 7 is fixed to the base portion 10 via the back support joint portion 8. The back support part 1, the handle support part (left) 3, the handle support part (right) 5, the handle part (left) 2, the handle part (right) 4, and the back support rotating part 6 are centered on the back support rotating part stopping part 601. Rotate as one. The distance L from the center of the back support rotating portion stopping portion 601 that is the center of rotation to the surface of the back support portion 1 is 2 to 15 cm (more preferably 5 to 10 cm). This is because a certain amount of movement of the backrest 1 is necessary to assist the rotation of the upper body of the user 15. Further, it is desirable that the vertical position of the backrest 1 is slightly above the position of the user's 15 hipbone. This is to assist stretching at a position closest to the side of the stomach. In addition, it is more effective if the backrest unit 1 is provided with a twist angle display unit 22 as shown in FIG. 7 and has a display function that serves as an index of the twist angle of the waist.

Next, the movable part of the present invention will be described with reference to FIG. FIG. 3A is a diagram for explaining the rotation of the seating portion 9, and FIG. 3B is a diagram for explaining the rotation of the backrest portion 1.

  The seating part 9 is installed on the upper part of the base part 10, and is pivoted to the base part 10 by a support part comprising a shaft part 11, a seating side bearing part 12, and a base side bearing part 13 provided on the bottom surface of the seating part 9. It is supported so as to be freely rotatable in a clockwise direction or a counterclockwise direction in a front view or a rear view. Therefore, the user 15 must use the muscles of the body to keep the seating surface horizontal when sitting. The maximum angle A of the inclination of the seating portion 9 is preferably about 10 to 20 degrees. If the angle is less than 10 degrees, the seating part 9 may come into contact with the base part 10 while the user 15 is balancing, and training for balancing may not be sufficiently performed. On the other hand, if the angle is greater than 20 degrees, the user 15 may slide off the seating surface before attempting to balance.

The back support portion 1 is flat or substantially flat, and the back support rotation portion 6, the back support support portion 7, and the back support joint portion 8 are offset from the center position of the back support portion 1 within the range of 50 mm to 100 mm rearward. And is pivotally supported by the base 10 and can be rotated clockwise or counterclockwise when viewed upward or downward.

Since the backrest 1 is used to assist the rotation of the upper body, it is desirable that the shape of the back be closer. Therefore, it is desirable that the shape is flat or slightly rounded. However, if the back rest 1 matches the shape of the back completely, the back rest 1 and the back will not fit when the back shape changes slightly during stretching. It is better to have a little gap between them.

Moreover, it is desirable to offset within the range of 50 mm-100 mm back from the center position of the backrest part 1, More preferably, it supports on the base part 10 in the position offset to 50 mm-100 mm.
This is because placing the rotation shaft at a position within such a range makes it easier to follow the movement of the upper body accompanying the rotation of the upper body of the user 15.

The maximum angle B of the backrest 1 is preferably about 30 to 45 degrees. If it is less than 30 degrees, the effect of stretching is small, and if it is 45 degrees or more, the amount of stretching performed by an individual is large, and there is a possibility that the body will be damaged by returning from stretching.

Next, the present invention and the movement of the user 15 will be described with reference to FIGS. FIG. 4 is a side view when the user 15 is seated on the chair of the present invention, and FIG. 5 is a diagram showing a process of stretching.

First, the user 15 is seated, the user's arm 1501 is lowered, and the user's 15 hand part 1502 has the handle part (left) 2 and the handle part (right) 4 facing down with the palm up. Hold as if wrapping. At that time, the sides are tightened, the shoulders are lowered backwards and the chest is stretched, and the scapulas approach each other. By this posture, the side is pulled upward. In this state, the user 15 also performs an operation of balancing using the waist portion so that the seating portion 9 is horizontal. By this operation, the deep muscles are actively used by tensioning the muscles of the lower back. From the standpoint of balancing, it may be possible to use only one central support point for the seating part 9, but doing so would require a great deal of effort, and it would not be possible to move the upper body. End up. Therefore, the structure is such that the balance operation can be performed by simply returning the inclination to the left and right, and the deep muscles near the stomach can be trained while reducing the difficulty of the balance operation.

The user 15 twists his / her waist as shown in FIG. Then, the back pad 1 also follows to some extent, but a gap like A is formed between the back and the back pad 1.
Then, the user 15 operates the handle part (left) 2 and the handle part (right) 4 to rotate the back support part 1 in a direction in close contact with the back, and further in the direction to rotate the upper body. Rotate 1 to assist in stretching the upper body.

Generally, there is no index for the rotational movement of the upper body to stretch the stomach, so it is difficult to stretch with a certain amount. On the other hand, in the present invention, since the stretch is assisted by the force of both arms, the user 15 can easily grasp the stretch amount by the movement of the arm, and a sufficient stretch amount can be ensured for the assist by the arm.

Another embodiment will be described with reference to FIG. Parts similar to those in the first embodiment are omitted. FIG. 6A is an example in which the inclination of the seating portion 9 is reduced by the spring 20, and FIG. 6B is an example in which the seat portion 9 is restrained by the speed damper 21 at which the seating portion 9 is inclined.

The spring 20 is fixed to the seating portion 9 and the base portion 10. One may be arranged on the left and right sides, or one in each of the four corners. The spring 20 generates a repulsive force when the seat portion 9 is tilted, and works so that the seat portion 9 returns to the horizontal. When the user 15 sits on the seat 9 and performs a balance operation so that the seat 9 does not tilt to the right or left, the user 15 is used by an unfamiliar person such as a beginner or a person who does not have high exercise ability In some cases, it is difficult to balance, and even the exercise of rotating the upper body after balancing is not achieved. Therefore, the spring 20 is used as an auxiliary function for balancing. The strength of the spring may be changed at the level of the user 15. If it is very difficult to balance, the spring 20 is strengthened. The seating part 9 can be kept horizontal with a little muscular strength. A person who does not know the knack for balancing may learn the knack for keeping the balance using the weak spring 20 and then remove the spring 20.

Further, a damper 21 may be used instead of the spring 20. This is because the use of the damper slows down the rotation speed of the seating section, making it easy for beginners to balance. Thus, since the movement of the instrument can be changed according to the level of the user, the present invention can be used widely from beginners to skilled workers.

  Another embodiment will be described with reference to FIG. FIG. 7A is a bottom view of the present invention. FIG. 7B is a side view of the present invention. Parts similar to those in the first embodiment are omitted.

In the present invention, since the rotation of the upper body is controlled by the force of the arm, it is easy to grasp the rotation amount. However, there is a case where it is desired to make a detailed training plan by controlling the rotation amount more quantitatively. For example, the upper body rotation amount is 30 degrees for the first week and 35 degrees for the next week. This embodiment is characterized in that the amount of rotation of the upper body is quantified.

The back support unit 1 is connected to the rotation shaft 701 through the back support rotation unit 6, and is integrated with the rotation interlocking unit 16 at the bottom of the base unit 10. By rotating the backrest unit 1, the rotation rotates the rotation interlocking unit 16 via the rotation shaft 701. The rotation restricting portion (right) 17 and the rotation restricting portion (left) 18 are disks for restricting the amount of rotation of the rotation interlocking portion 16, and both the rotation restricting portion (right) 17 and the rotation restricting portion (left) 18 are the rotation interlocking portion 16. Restriction bosses 1701 and 1801 are provided for restricting the above. The rotation restricting portion (right) 17 and the rotation restricting portion (left) 18 are in contact with each other at a substantially central portion of the base portion 10 and transmit one rotation without sliding to the other. Although not shown, a dial 19 is fixed to the rotation restricting portion (left) 18. The dial 19 is a dial for the user to set the amount of rotation restriction. By rotating a portion protruding from the side surface of the base portion 10 by hand, the rotation restriction portion (right) 17 and the rotation restriction portion (left). 18 rotates, the positions of the restricting bosses 1701 and 1801 change, and the amount of restriction of rotation of the rotation interlocking portion 16 can be changed.

  The armpit stretcher chair according to the present invention is provided with the above-described back rest and seating portion, so that the armpit stretch can be performed more effectively, comprehensively and simply than before, and the industry relating to health promotion and beauty. We understand that the above applicability is great.
