  The present invention has been invented in view of the above-described conventional problems, and can selectively enhance the exercise effect aiming at a specific part of the body, and is safe and optimal for long-term exercise. It is an object of the present invention to provide a dynamic exercise device.

In order to solve the above-described problems, the present invention provides a seat 2 on which a user is seated, an exercise device main body 1A including the seat 2, and a seat swing that swings the seat 2 to apply an exercise load to the user. An oscillating exercise device including the device 3, wherein the handle 30 that supports the user's body at the front F and the rear B of the seat 2 is controlled in the vertical movement with respect to the seat 2. The mounting structure is free to rotate within a constant angle range, and a spring 32 is provided for applying a spring force for returning the handle 30 to a fixed direction.

By adopting such a configuration, when the balance training is performed while sitting on the swinging seat 2, the handle 30 provided in front of and behind the seat 2 and whose vertical movement is restricted with respect to the seat 2 is provided. By grasping, the user can exercise safely even when sitting backward or sideways other than forward. Moreover, by sitting backwards or sideways, exercise load different from the case of facing forwards is given, especially in the case of sideways, there is a way to support the body with both arms without supporting the body with the thigh. In particular, a stretching effect for intensively training specific parts of the body such as arms, chests, and shoulders can be obtained. As a result, the exercise effect can be selectively enhanced aiming at specific parts of the body. In addition, since various exercise effects can be obtained by riding differently from the conventional forward direction, it is optimal to continue exercising for a long time without getting tired.

  Further, the handle 30 has a rotation-free mounting structure within a fixed angle range, so that when the handle 30 is supported by holding the handle 30, the handle 30 is fixed so as not to rotate. Since 30 rotates, it becomes difficult to balance, and as a result, a movement effect becomes large. That is, when the handle 30 has instability with respect to the user, it is possible to obtain a flexibility effect that particularly increases the movable range of the shoulder joint, the arm joint, and the wrist joint.

  In addition, since the spring 30 for applying the spring force for returning the direction of the handle 30 to the fixed direction is provided on the handle 30 that is free to rotate within the above-mentioned fixed range of angles, the grip 30 is easy to be gripped and easy to use when seated. In addition to the structure, the user can train the muscles of the hand, arm, and shoulder by gripping the handle 30 and rotating it with its own force in a direction opposite to the spring force. In particular, when performing balance exercise, the handle 30 can be turned to work the muscle against the force of the spring 32 and muscle training can be performed, which is optimal for muscle strengthening exercise.

  In addition, the rear B handle 30b is preferably disposed in the center of the rear B of the seat 2. In this case, for example, the user can sit on the seat 2 sideways and support the body with both arms. This will give you more benefits in hand, arm and shoulder movements.

  Further, the rear B handle 30b is preferably disposed on the left and right sides B of the seat 2. In this case, for example, the rear B left and right handles 30 are held with both arms while sitting forward on the seat 2. It can take a posture of grasping and supporting the body, and further effects can be obtained for the exercise of the shoulder, chest, abdomen, and thigh.

  Further, the front F handle 30f is preferably arranged on the front F left and right sides of the seat 2, and in this case, for example, the front F left and right handles 30f are held with both arms in a state of being seated rearward on the seat 2. It can take a posture of grasping and supporting the body, and further effects can be obtained for the exercise of the shoulder, chest, abdomen, and thigh.

The swing type exercise device according to the present invention includes grips for supporting the user's body in front and rear of the seat, so that the user can exercise safely even when sitting backward or sideways other than forward. In addition, by sitting backwards or sideways, an exercise load different from the forward direction is applied, and further, the range of angles is constant in a state where the vertical movement with respect to the seat is restricted. With a spring force to return the direction of the rotation-free handle to a certain direction, it is easy to grip the handle when seated, and the structure is easy to use. It is difficult to balance and enhance the exercise effect, and you can work the muscles by turning the handle against the spring force. Result, it is possible to increase the selective exercise effect aimed at specific body part, an optimum for continued long exercise.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 1, a swing type exercise device 1 according to the present invention is provided in a seat 2 on which a user sits in a shape imitating a horse's back and a saddle, and is provided in the seat 2, and the seat 2 is arranged in at least one direction.

A hook 26 for hanging a user's foot from both sides of the seat 2 is suspended and attached, and a bridle 31 is attached to the front F center of the seat 2.

  6 to 9 show an example of the seat swinging device 3. 6, 7, and 9, a state in which the seat swing device 3 swings is indicated by a virtual line. A pedestal 4 to which the seat 2 is attached is supported by a movable frame 6 so as to be able to swing back and forth via a pair of connecting links 5 that are paired on the left and right sides, and the movable frame 6 is supported by a base 8 so as to be able to swing left and right. In addition, a drive unit 13 is accommodated between the base 4 and the movable mount 6. The connecting link 5 includes a front link 5a and a rear link 5b. The upper end portion of the front link 5a is pivotally attached to the upper shaft pin 2a provided at the front end portion of the base 4, and the lower end portion of the front link 5a is pivoted to the lower shaft pin 7a provided at the front end portion of the side plate 16 of the movable frame 6. It is worn. The upper end portion of the rear link 5b is pivotally attached to the upper shaft pin 2b provided at the rear end portion of the base 4, and the lower end portion of the rear link 5b is the lower shaft pin provided at the rear end portion of the side plate 16 of the movable frame 6. It is pivotally attached to 7b. The front and rear lower shaft pins 7a and 7b constitute a left and right shaft 7 that supports the connecting link 5 so as to be rotatable about the axis in the left and right direction y, whereby the pedestal 4 is moved around the left and right shaft 7 as shown in FIG. Can be reciprocally rotated in the front-rear direction indicated by the arrow θy.

  As shown in FIGS. 7 and 9, shaft support plates 24 are erected on both ends of the base 8 in the front-rear direction x, and the shaft support plates 24 are disposed on both ends of the movable mount 6 in the front-rear direction x. Are connected to the shaft support plate 24 so as to be rotatable by the front and rear shafts 9. The front and rear shafts 9 are arranged at two positions in the front and rear of the center portion of the base 8 to support the movable mount 6 so as to be rotatable around the front and rear shafts 9. Reciprocating rotation is possible in the left-right direction indicated by θx.

  On the other hand, the drive unit 13 uses the rotational force of the single motor 10 and the output rotary shaft 12 of the motor 10 to reciprocate linearly in the front-rear direction x of the pedestal 4, to rotate reciprocally about the left-right axis 7, and to rotate about the front-rear axis 9. Two drive units 13a and 13b that can convert the reciprocating movement and drive the seat 2 by combining these three operations are provided. The motor 10 of this example is placed vertically on the movable gantry 6, and the protruding direction of the output rotating shaft 12 is upward.

  The first drive unit 13a is for reciprocating linear movement in the front-rear direction x and rotational reciprocation about the left and right axis 7, and the second drive unit 13b is for reciprocating rotation about the front-rear axis 9. As shown in FIGS. 7 and 8, the first driving unit 13 a includes a first shaft 17 connected to the output rotation shaft 12 via the motor gear 11 and the first gear 14, and one end of the first shaft 17. An eccentric crank 19 connected eccentrically and an arm link 20 having one end connected to the eccentric crank 19 and the other end attached to a shaft pin 5c provided on the front link 5a. Both end portions of the first shaft 17 are rotatably supported on the movable frame 6 side, and the eccentric crank 19 performs an eccentric circular motion with respect to the first shaft 17, whereby the front link is connected via the arm link 20. 5a reciprocates in the front-rear direction x, so that the pedestal 4 connected to the connecting link 5, that is, the seat 2, can swing in the direction indicated by the arrow θy in FIGS.

  Further, as shown in FIGS. 8 and 9, the second driving unit 13 b has a second shaft 18 connected via the interlocking gear 22 of the first shaft 17 and the second gear 15, and one end portion of the second driving unit 13 b is second. An eccentric rod 21 that is eccentrically connected to one end portion of the shaft 18 and is rotatably connected to the base 8 is configured. Both ends of the second shaft 18 are rotatably supported on the movable frame 6 side. The eccentric rod 21 is arranged on either the left side or the right side of the base 4 (right side in FIGS. 8 and 9), and the upper end portion 21a of the eccentric rod 21 is connected to one end of the second shaft 18 by the shaft pin 62 shown in FIG. The lower end portion 21 b of the eccentric rod 21 is connected to an L-shaped connecting bracket 27 fixed to the base 8 by a shaft pin 61 so as to be rotatable. Therefore, the rotation of the second shaft 18 causes the upper end portion of the eccentric rod 21 to perform an eccentric circular motion, so that the pedestal 4, that is, the seat 2 rotates and reciprocates around the front-rear axis 9 as indicated by the arrow θx in FIG. 9. It is possible.

  According to the above configuration, when the output rotation shaft 12 protruding in one direction of the motor 10 rotates, the first shaft 17 rotates due to the engagement between the motor gear 11 and the first gear 14 and at the same time, the interlocking gear 22 of the first shaft 17. The second shaft 18 is rotated by meshing with the second gear 15. When the first shaft 17 rotates, an eccentric crank 19 connected to one end portion of the first shaft 17 performs an eccentric circular motion, and the front link 5a via the arm link 20 moves in the front-rear direction x about the left and right shafts 7 on the front side. To turn. Since the rear link 5b cooperates and rotates about the rear left and right axis 7, the base 4, that is, the seat 2, reciprocates and swings in the front-rear direction x. On the other hand, due to the rotation of the second shaft 18, the upper end portion of the eccentric rod 21 performs an eccentric circular motion, and the pedestal 4, that is, the seat 2 rotates and reciprocates around the longitudinal axis 9.

  When the user is seated on the seat 2, the seat 2 moves in the front-rear direction x, the left-right direction y, the up-down direction z, and the θx direction and the θy direction as shown in FIGS. By swinging, it is possible to give the user a feeling close to that of actual riding, and to train the balance function and the exercise function of the body. Further, since a single motor 10 is sufficient, the number of motors 10 is reduced, the control is simplified, and the cost and the size can be reduced. In addition, the output rotation shaft 12 of the motor 10 only needs to protrude in one direction, and when it is protruded in two directions, it can be placed horizontally, but in this example, it can be placed vertically. It is possible to reduce the installation space of the entire seat swinging device 3 including the seat swinging device, and to store the seat swinging device 3 in the seat 2 to faithfully reproduce the intended operation imitating riding. It becomes possible.

  Here, in the present invention, as shown in FIG. 1, the reins 31 at the front F center of the seat 2, the handles 30 f at the front F left and right of the seat 2, and the handles 30 b at the rear B center and rear B left and right of the seat 2, respectively. It is arranged. Each handle 30 (30f, 30b) is formed in a semicircular shape that rises upward from the seating surface of the seat 2. It is thick enough to be grasped by the hand, has a hole that can be easily inserted by the hand, and is made of a material made of plastic or metal that can be firmly grasped.

  Similar to the handle 30, the reins 31 are formed in a semicircular shape, are fixed to the front F center of the swinging seat 2, and also function as a front center handle. The reins 31 of the present example are self-supporting and are held in a standing state that falls to the rear B (user side) from directly above, and are prevented from being displaced forward F than the standing state. ing.

  FIG. 2 shows how to sit on the side and support the body with both arms by gripping the reins 31 of the front F and the handle 30b at the center of the rear B. FIG. 3 shows a riding method in which the user sits rearward and holds the body by gripping the grips 30f arranged on the front F left and right sides of the seat 2 with both hands. Of course, FIGS. 2 and 3 are only examples of usage, and various other usages are possible.

  Thus, when performing balance training by sitting on the swinging seat 2, the user can hold the handle 30 and the reins 31 provided at the front and rear of the seat 2, so that the user can sit back or sideways other than forward. You will be able to exercise safely.

  Moreover, by sitting backwards or sideways, an exercise load different from the forward direction is applied, and especially when the sideways, the body and the chest are supported by supporting the body with the reins 31 and the handle 30. , Effective in shoulder movement. In this way, the stretch effect for intensively training a specific part of the body is obtained by the way of riding that supports the body with both arms without supporting the body with the thigh, and as a result, selective aiming at the specific part of the body You will be able to enhance the exercise effect. In addition, since various exercise effects can be obtained by riding differently from the forward direction, tiredness is not born and it is optimal for continuing exercise for a long time. If you become more accustomed, for example, you can hold the grip 30 or the reins 31 with one hand, make the other hand free, and perform a balance exercise by turning the arm greatly.

  Each handle 30 (30f, 30b) is not limited to the case where the handle 30 is fixed to the front and rear of the seat 2, but the handle 30 may have a mounting structure that is free to rotate with respect to the seat 2 within a fixed angle range. FIG. 4 shows an example. In FIG. 4, the shaft portion 33 protruding from the center of the lower end of the handle 30 is rotatably inserted into the bearing portion 34 assembled by a pair of half-cracked bearing brackets 34 a and 34 b, and laterally from the shaft portion 33. With the protruding stopper 35 being slidably inserted into a lateral hole 36 formed in the bearing fittings 34a and 34b, the bearing portion 34 is fixed to the exercise device body 1A side. In this state, the shaft portion 33 is rotatable in the bearing portion 34, and the vertical movement of the shaft portion 33 is restricted by the upper and lower walls 36 a and 36 b of the lateral hole 36. The rotation angle θ of the shaft portion 33 is regulated by the left and right walls 36c and 36d of the lateral hole 36 in which the stopper 35 is inserted.

  Thus, by attaching the handle 30 to the seat 2 in a rotation-free manner within a certain angle θ range, the handle 30 is fixed so as not to rotate when the handle 30 is held and the body is supported. Since the handle 30 rotates, it becomes difficult to achieve a balance, and as a result, the exercise effect increases. That is, the handle 30 can be unstable to the user, and the effect of training the body can be further enhanced, and in particular, the flexibility effect of increasing the movable range of the shoulder joint, arm joint, and wrist joint can be obtained. Can do.

  FIG. 5 shows an example in which a spring 32 that applies a spring force for returning the direction of the handle 30 to a fixed direction is provided on the handle 30 that is free to rotate within the range of the angle θ. Other configurations are the same as those in FIG. 4, and corresponding portions are denoted by the same reference numerals. In this example, a structure is shown in which the handle 30 has a constant angle rotation free structure and returns to the center by the force of the spring 32. Specifically, a coil spring 32 is attached to a shaft portion 33 provided with a stopper 35 for regulating the rotation angle θ of the handle 30. One end side 32a of the coil spring 32 is inserted into a hole portion (not shown) provided in the shaft portion 33, and the other end side 32b of the coil spring 32 is inserted into a hole portion 37 provided at the center upper portion of the bearing fittings 34a, 34b. The spring force is applied so that the stopper 35 returns to the center direction of the lateral hole 36. Thus, even when the handle 30 has a constant angle rotation free structure, the handle 30 returns to the center direction of the lateral hole 36 by a spring force, so that the handle 30 is gripped when seated, unlike the case where the coil spring 32 is not provided. Easy to use and easy to use. In addition, the user can train the muscles of the hand, arm and shoulder by gripping the handle 30 and rotating it with his / her own force in a direction opposite to the spring force. In particular, when performing balance exercise, the handle 30 can be turned and the muscles can be exercised against the force of the coil spring 32, so that muscle strength training can be performed.
