Description

  The present invention relates to an exercise chair, and more particularly, to an exercise chair that enables rotational movement of the waist and back and forth movement of the waist while sitting on the chair.

  In general, modern people are not bound to exercise because they are restricted by work and time and do not have time to exercise. For this reason, there is a desire to avoid chronic fatigue and various diseases due to lack of exercise, but even if exercise time and exercise location are secured, there are many people who are more lazy than exercising eagerly. This is to avoid fatigue due to exercise, and it is difficult to make exercise habits even though it is known that exercise is good for the body.

  Under these circumstances, in recent years, methods have been provided that can be enjoyed and exercised without much difficulty. That is, for example, there is provided a method in which a seat motion of a chair rotates and a waist motion is automatically performed only by sitting on the chair. According to such a method, not only a great effort can be achieved but also an exercise effect can be achieved, and in particular, persons with disabilities can also enjoy exercise easily.

  However, in order to rotate the seat plate of the chair, the rotational power must be transmitted to the seat plate. However, when the rotational power of the motor is transmitted to the seat plate of the chair and rotated, the rotational power of the motor is not transmitted. There is a problem that the vibration noise is transmitted together during transmission and cannot concentrate on the movement. Further, there is a problem that not only the rotation is not performed flexibly, but also a high horsepower motor is required to increase the driving force during low-speed rotation.

  Therefore, the object of the present invention is a novel and improved technique that can prevent vibration and noise caused by rotation and movement of the seat plate, and that the rotation and drive of the seat plate can be sufficiently exerted even with a driving force at a low speed rotation. Is to provide an athletic chair.

  In order to solve the above problems, in the first aspect of the present invention, a permanent magnet (140) is provided concentrically below the rotating plate (120) to which the seat plate (101) is eccentrically coupled. , A rotating chair in which an electromagnet (130) is provided concentrically on an upper portion of a fixed plate (110) coupled to a lower portion of the rotating plate (120), and the seat plate (101) is formed to be rotatable. 100) and a square fixed to the lower part of the moving plate (220) above the electromagnet (250) at the front and rear at a predetermined interval, and the electromagnet (250) is provided at an upper portion of the floor frame (215). A rod (240) and a permanent magnet (230) are provided so that the movable plate (220) can be moved back and forth, and a seat plate (201) coupled to the upper portion of the movable plate (220) can be moved back and forth. Formed back and forth movement A child (200), made of, are provided exercise chair, characterized in that.

  In the invention described above, since the seat plate of the chair is rotated and moved back and forth in a non-contact manner using an electromagnet and a permanent magnet, vibration and noise caused by the rotation and back and forth movement of the seat plate are prevented. Because of its excellent driving force during low-speed rotation, the rotating force and driving force of the seat plate can be fully demonstrated even with a small amount of power. As a result, it is possible to perform a lower back exercise and an aerobic exercise without requiring a great deal of effort while sitting on a chair, and a healthy body can be maintained. In addition, people with disabilities who are disabled can also exercise.

  According to the present invention, a waist exercise and aerobic exercise can be performed without requiring a great amount of labor in a state where the chair is seated on the waist, and a healthy body can be maintained. In addition, people with disabilities who are disabled can also exercise.

  In addition, the chair's seat can be rotated and moved back and forth, so that the user can move and move his / her hips only by sitting on the seat, especially using electromagnets and permanent magnets. The seat plate can be rotated or moved in a non-contact manner. In addition, disabled people with limited mobility can rotate their hips and move back and forth simply by sitting down, so they can prevent the occurrence of illness due to lack of exercise and maintain their health. It becomes like this. In addition, the hips can rotate and move back and forth while the two are facing each other, and the hips can be rotated and moved back and forth separately.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, constituent elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 1, the exercise chair according to the present embodiment includes a rotary chair 100 including a seat plate 101 that performs a rotational motion, and a front and rear moving chair 200 including a seat plate 201 that moves back and forth. The swivel chair 100 and the forward / backward moving chair 200 can be provided so as to face each other, or can be provided and used independently. Further, the swivel chair 100 and the forward / backward moving chair 200 can be coupled or separated by a coupling means such as a screw.

  As shown in FIGS. 2, 3, and 8, the swivel chair 100 according to this embodiment is configured such that the seat plate 101 can be rotated using an electromagnet 130 and a permanent magnet 140 whose polarities periodically change. . A seat plate 101 is fixed to the top of the X bar 102, and the height of the X bar 102 is adjusted by a cylinder 103 that is expanded and contracted by a motor. A fixing plate 110 with an electromagnet 130 is fixed on the X bar 102. A support shaft 121 fixed at the center of the rotating plate 120 is coupled via a bearing 111 formed at the center of the fixed plate 110. A permanent magnet 140 is fixedly disposed below the rotating plate 120, and an eccentric output shaft 122 is provided above the rotating plate 120. The center of the seat plate 101 of the rotary chair 100 is coupled to the eccentric output shaft 122 via a bearing 123.

  In the swivel chair 100 according to this embodiment, an X bar 102 is provided on an upper portion of a floor frame 105, and the X bar 102 is enlarged or reduced by a cylinder 103 that is expanded and contracted by a motor. As a result, the height of the chair 100 is adjusted. Since the structure of the X bar 102 is a known structure, and the process of extending and contracting the X bar 102 with the cylinder 103 is also known, detailed description thereof is omitted.

  The seat plate 101 according to the present embodiment is rotatably coupled to the upper portion of the X bar 102. A fixed plate 110 is fixed to the top of the X bar 102. At this time, a bearing 111 to which the support shaft 121 is rotatably coupled is fixed at the center of the fixed plate 110. The electromagnets 130 are arranged at equal intervals along the periphery of the bearing 111.

  The electromagnet 130 is supplied so as to have a phase difference of 120 ° after being converted into three phases by an inverter by the input of a DC power source.

  A rotating plate 120 is coupled to the upper portion of the fixed plate 110. In the rotating plate 120, a support shaft 121 protruding from the lower center is fitted into the bearing 111 of the fixed plate 110. Permanent magnets 140 are arranged at equal intervals below the rotating plate 120, and an eccentric output shaft 122 is provided above the rotating plate 120. The eccentric output shaft 122 is coupled to the lower portion of the seat plate 101 with a bearing 123.

  Here, as shown in FIG. 4, the electromagnet 130 fixed to the fixed plate 110 may be composed of six pieces, and the permanent magnet 140 fixed to the rotating plate 120 may be composed of eight pieces. It can also consist of 5 or 5. That is, both the electromagnet 130 and the permanent magnet 140 need to satisfy both a condition of equidistant arrangement and a condition that the numbers thereof are different from each other.

  Furthermore, the seat plate 101 according to the present embodiment is returned by the spring 150 when the backrest 107 of the rotary chair 100 is connected to the rear via the spring 150 and the seat plate 101 of the rotary chair 100 performs a rotational motion. You will receive power.

  Further, in this embodiment, the fixed plate 110 and the rotating plate 120 are provided with photocouplers (not shown), respectively, so that the rotation amount and the rotating position of the rotating plate 120 are detected and the initial position of the rotating plate 120 is set. And the rotation speed can be adjusted.

  On the other hand, the forward / backward moving chair 200 that is coupled and installed in front of the swivel chair 100 or can be used alone moves the seat plate 201 back and forth. It is never perceived. A moving plate 220 having a seat plate 201 of the forward / backward moving chair 200 fixed to the upper portion moves like a swing. Permanent magnets 230 and square bars 240 are fixed at a certain distance on the front and rear of the lower part of the moving plate 220, and electromagnets 250 are provided on the front and rear of the floor frame 215, respectively. Therefore, the seat plate 201 is moved like a swing by the magnetic force of the electromagnet 250 and the magnetic force of the permanent magnet 230 and the square bar 240.

  As shown in FIGS. 12 to 15, the forward / backward moving chair 200 according to the present embodiment moves the seat plate 201 in the forward / backward direction like a swing. A support base 212 is fixed to the lower center of the seat plate 201, and the support base 212 is erected at the center of the moving plate 220. Connecting bars 221 are coupled to both sides of the moving plate 220 by hinges 222. The upper portion of the connecting bar 221 is coupled to a fixing plate 223 fixed to the cover 213 or the floor frame 215 via a bearing hinge 224.

  The moving plate 220 moves back and forth like a swing while being lifted by the connecting bar 221. The seat plate 201 fixed to the support base 212 at the center of the moving plate 220 also moves back and forth like a swing like the moving plate 220. A spring 225 is fixed to the cover 213 in front of the moving plate 220 to provide a restoring force when the moving plate 220 moves back and forth.

  At the lower part of the moving plate 220, a square bar 240 and a permanent magnet 230 are provided at a predetermined distance from each other at the front and rear, and an electromagnet 250 is provided at the floor frame 215 positioned at the lower part of the moving plate 220. The electromagnet 250 is provided so as to be positioned between the square bar 240 and the permanent magnet 230. Here, when the electromagnet 250 is inclined inward and the moving plate 220 moves back and forth, the distance between the upper portion of the electromagnet 250, the permanent magnet 230, and the square bar 240 is kept constant. Like that.

  The electromagnet 250 is supplied with a PWM current so that the polarity of the electromagnet 250 changes periodically. The permanent magnet 230 is positioned inside the moving plate 220, while the square bar 240 is positioned outside. The permanent magnets 230 are arranged to have the same polarity, and the square bar 240 has a polarity opposite to that of the permanent magnet 230 according to the polarity of the permanent magnet 230.

  Accordingly, when a current is applied to the electromagnet 250 to make it polar, the polarity of the electromagnet 250 and the polarity of the permanent magnet 230 and the square bar 240 are the same or opposite. Therefore, the polarity of the electromagnet 250 is changed to change the permanent magnet 230. The square bar 240 is pushed or pulled, so that the moving plate 220 moves back and forth, and the seat plate 201 also moves back and forth.

  The exercise chair having the above configuration can be used by using the swivel chair 100 and the front / rear moving chair 200 alone or by combining them in a state of facing each other. Each will be described, and the description of the operation process in a state of being coupled to face each other will be omitted.

  First, the operation of the swivel chair 100 will be described.

  The seat plate 101 according to the present embodiment is coupled to an eccentric output shaft 122 protruding from the upper portion of the rotating plate 120 by a bearing 123 and rotates by an eccentric amount of the eccentric output shaft 122 when the rotating plate 120 rotates. When the seat plate 101 rotates, the spring 150 is coupled to the rear on both sides, so that the rotation is performed smoothly.

  Since the support shaft 121 protruding from the lower portion of the rotating plate 120 is fitted to the bearing 111 fixed to the center of the fixed plate 110, the rotating plate 120 rotates around the support shaft 121, and the fixed plate 110 further Fixed to the top of the X bar 102.

  An electromagnet 130 is fixed to the upper part of the fixed plate 110, and a permanent magnet 140 is fixed to the lower part of the rotating plate 120. In the present embodiment, since the polarity of the electromagnet 130 is changed by changing the direction of the current applied to the electromagnet 130, the rotating plate 120 is rotated by the tensile force pressing force between the electromagnet 130 and the permanent magnet 140.

  As described above, when the rotating plate 120 rotates in accordance with the polarities of the electromagnet 130 and the permanent magnet 140 at the upper portion of the fixed plate 110, the seat plate 101 coupled to the eccentric output shaft 122 rotates at the upper portion of the rotating plate 120. At this time, since it is coupled to the backrest 107 of the chair 100 by the spring 150 behind the seat plate 101, the rotational movement is performed smoothly.

  The electromagnet 130 according to the present embodiment is supplied with a phase difference of 120 ° by converting a DC power source into a three-phase current with an inverter. Can be rotated flexibly. The permanent magnet 140 is configured so that the polarities of magnets adjacent to each other are opposite.

  As described above, in the exercise chair in which the electromagnet 130 and the permanent magnet 140 according to the present embodiment are arranged, a process in which the rotating plate 20 rotates counterclockwise will be described with reference to FIGS.

  At this time, when the electromagnet 130 and the permanent magnet 140 are placed as shown in FIG. 5 and a current is applied to the electromagnet 130 to have the polarity as shown in FIG. The electromagnet 131 generates a pressing force, the electromagnet 132 pulls the permanent magnet 142 while pushing the permanent magnet 143, the electromagnet 133 pulls the permanent magnet 143 while pushing the permanent magnet 144, and the electromagnet 134 pushes the permanent magnet 145. , The electromagnet 135 pulls the permanent magnet 146 while pushing the permanent magnet 147, the electromagnet 136 pulls the permanent magnet 147 while pushing the permanent magnet 148, and the electromagnet 130 and the permanent magnet 140 mutually push and pull. Since the force acts, the rotating plate 120 starts to rotate counterclockwise.

  When rotating in the counterclockwise direction, the polarity of the electromagnet 130 is applied differently, so that the polarity of the electromagnet 130 is reversed as shown in FIGS. In this case, the pressing force and the pulling force of the electromagnet 130 and the permanent magnet 140 are changed, but the permanent magnet 140 is pulled or pushed from the electromagnet 130 as a whole. The fixed rotating plate 120 rotates counterclockwise.

  Further, the polarity of the current applied to the electromagnet 130 is applied with a phase difference of 120 °, and the number of the permanent magnets 140 and the electromagnets 130 are different, so that the rotating plate 120 is rotated. At this time, the speed of the rotating plate 120 increases as the period of changing the polarity of the current is increased.

  On the other hand, the rotating plate 120 according to the present embodiment stops immediately when the supply of current is interrupted, and the magnetic force of the permanent magnet 140 acts on the metal fixed plate 110 to stop, so that the rotating plate 120 stops. The rotation direction of the rotating plate 120 is determined by how the polarity of the current is applied. That is, when the polarity of the current is applied to the electromagnet 130 as shown in FIGS. 5 to 7, the rotating plate 120 rotates counterclockwise, but when it is applied as shown in FIGS. Rotate in the direction.

  Therefore, the rotation direction of the rotating plate 120 is determined by changing the polarity of the current applied to the electromagnet 130. When the polarity applied to the electromagnet 130 changes with the rotating plate 120 stopped, the rotating plate 120 rotates in the opposite direction. On the other hand, when the polarity of the current changes with the rotating plate 120 rotating in one direction, The rotating plate 120 continues to rotate. Therefore, when the rotation starts from a state where the rotating plate 120 is stopped, if the polarity of the current is changed, the rotation speed in the rotation direction is determined by the speed of the polarity. On the other hand, when the rotating plate 120 is stopped from the rotating state, if the polarity of the current is changed, the rotating direction of the rotating plate 120 is reversed.

  A photocoupler (not shown) or the like is provided on one side of the rotating plate 120 and the fixed plate 110 according to the present embodiment, and the rotational position and rotational speed of the rotating plate 120 can be detected.

  The rotation plate 120 is rotated by a support shaft 121 fitted to a bearing 111 fixed to the fixed plate 110, and the eccentric output shaft 122 is rotated by the rotation of the rotation plate 120. Since the eccentric rotating shaft 122 is coupled to the seat plate 101 by the bearing 123, the seat plate 101 rotates while drawing a small concentric circle as the rotating plate 120 rotates.

  At this time, since the back plate 107 and the spring 150 are coupled to the back of the seat plate 101, the concentric circle can be easily rotated. When the spring 150 is not provided, the eccentric rotation of the seat plate 101 causes the seat plate 101 to rotate. Rotational vibration occurs.

  Thus, in the present embodiment, the seat plate 101 is rotated by the mutual pressing force and tensile force of the electromagnet 130 and the permanent magnet 140, so that no vibration noise is generated and a large force can be produced even at low power. Therefore, it is effectively used to exercise while sitting on the chair 100.

  Next, the operation of the forward / backward moving chair 200 will be described with reference to FIGS.

  In the state where the permanent magnet 230 according to the present embodiment is N-pole, and thus the square bar 240 is S-pole, current is supplied to the electromagnet 250 as shown in FIG. When the polarities of the electromagnets 250 are reversed, the permanent magnets 230 and the square bars 240 have a mutual tensile force pressing force according to the polarities of the electromagnets 250. Accordingly, the moving plate 220 moves forward as shown in FIG. 17, and when the direction of the current flowing through the electromagnet 250 is changed in this state, the electromagnet 250 has the opposite polarity and is opposite to that shown in FIG. A tensile force is generated, and the moving plate 220 moves rearward as shown in FIG. When this process is repeated, the moving plate 220 moves like a swing in the front-rear direction, and the seat plate 201 also moves back and forth.

  At this time, the spring 225 expands and contracts due to the movement of the moving plate 220 and assists the restoring force of the moving plate 220.

  As described above, when the permanent magnet 230 is arranged so that the side facing the square bar 240 is an N pole, the square bar 240 becomes magnetic by the permanent magnet 230, and the side facing the permanent magnet 230 is the S pole. It becomes. In this state, when the electromagnet 250 fixed to the upper part of the floor frame 215 between the square bar 240 and the permanent magnet 230 supplies current such that the front is the S pole and the rear is the N pole, The electromagnet 250, the permanent magnet 230, and the square bar 240 have a pressing force against each other. However, since the electromagnet 250 is fixed to the floor frame 215, the permanent magnet 230 is pushed or pulled. At the same time, the square bar 240 and the permanent magnet 230 have different polarities, and a tensile force and a pressing force are applied to each other. Therefore, the square bar 240 and the permanent magnet 230 are pushed by the fixed electromagnet 250. The moving plate 220 moves forward as shown in FIG.

  In this state, if the direction of the current flowing through the electromagnet 250 is reversed, the front electromagnet 250 has the NN pole, and the rear electromagnet 250 has the S polarity. Therefore, the square bar 240 and the electromagnet 50 have a pressing force and a tensile force. Furthermore, since the permanent magnet 230 and the electromagnet 250 also have a tensile force or a pressing force, the moving plate 220 moves rearward as shown in FIG.

  Furthermore, if the polarity of the electromagnet 250 is changed again after the moving plate 220 moves as shown in FIG. 19, the moving plate 220 moves again in the opposite direction. Eventually, when the direction of the current applied to the electromagnet 250 is periodically changed, the moving plate 220 moves in the front-rear direction, so that the seat plate 201 fixed to the moving plate 220 also moves in the front-rear direction so that the swing moves. To move on.

  At this time, the moving plate 220 is coupled to the connecting bar 221 by the hinge 222, and the other side of the connecting bar 221 is coupled to the fixed plate 223 by the bearing hinge 224. As a result, the moving plate 220 is lifted by the connecting bar 221 so as to move back and forth like a swing, and the permanent magnet 230 and the square bar 240 do not pass the upper part of the electromagnet 250 when moving. So that the moving plate 220 can move back and forth.

  Therefore, when sitting on the back-and-forth moving chair 200, it is possible to perform the forward and backward movement and the aerobic movement according to the cycle of changing the polarity of the electromagnet 250 without separately applying force, so that the exercise effect is easily achieved. be able to.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
