It is explanatory drawing.

  In each of the drawings, the exercise device according to the present embodiment includes a seat portion 10 in which a user is seated in a sitting posture with the front facing forward, elbow support portions 11 formed on both lateral sides of the seat portion 10, A drive unit 50 that swings the seat unit 10, the elbow support unit 11 is rotatable about the lateral end of the seat unit, and the inner side surface of the elbow support unit 11 is rotated by rotating the elbow support unit 11. In the closed state in which is substantially parallel to the seating surface, it can be seated in a riding posture with its front facing backward with respect to the outer surface of the elbow receiving portion 11. Moreover, the exercise device according to the present embodiment has a configuration in which the seat portion 10 bends and functions as a backrest, and a grip portion 30 that a user grips is formed on the upper portion of the backrest portion.

An air cell is disposed at the bottom of the inner side surface of the elbow support 11, and the user can be stably held by expansion due to supply of air from an air pump and a compressor (not shown).
Metal brackets 18 (not shown) are provided at two locations on the front side and the rear side of the inner bottom portion of the elbow support 11, and are attached to an opening / closing shaft of the seat body 13. Thereby, the elbow receiving part 11 is rotatable with respect to the seat part 10. The longitudinal length of the elbow receiving portion 11 is half of the lateral length of the seat portion 10, and when the elbow receiving portion 11 is turned to the closed state, the seat portion 10 and the elbow receiving portion 11 have an integrated shape. (See FIG. 2). Moreover, when the cushion material is arrange | positioned continuously in the center part of the outer side surface of the elbow receiving part 11, and the center part of the bottom part, and the user sits straddling back on the outer side surface of the elbow receiving part, The cushion material disposed on the elbow support 11 softly supports the user's buttocks and inner thighs, absorbs shock even during driving, and the user does not feel pain at the wearing part (FIG. 6). reference). An operation panel for a riding posture is formed on the upper portion of the backrest portion of the seat portion 10.

  When the user sits in the sitting position with the elbow receiving portion 11 in the open state and when the user sits in the riding posture with the elbow receiving portion 11 in the closed state, the seat portion 10 swings by the driving portion 50 in each posture. Since the muscles used and the state of the muscles used are different, the muscles to be strengthened are greatly affected, and even the same rocking can be experienced differently by the same user. In addition, when used by multiple users of different age groups, it can be used in a seated posture, which is a comfortable posture if it is an elderly user, and in a horse riding posture if it is a user of a middle age group. It is possible to perform exercises that match each user.

  The seat portion 10 is composed of a seat body 13 formed by molding a metal material or fiber-reinforced plastic into a predetermined shape, and a cushion material and a cover 16 are pasted on the upper surface of the seat body 13. The rear portion of the seat body 13 has a function as a backrest that bends and supports the user's back in the seated state. By doing so, a user can sit down with the elbow support part 11 stably. In addition, the cushion material on the upper surface of the seat body 13 has a shape in which the front center part is raised, and supports the user's inner knees and inner thighs while seated, contributing to stable seating. ing.

One end of a footrest frame (step frame) 80 is joined to the front surface of the exterior 51 of the drive unit 50, and a step 81 for footrest is attached to the other end of the footrest frame 80. A stable posture can be obtained by placing a foot on this step 81 and sitting in a sitting posture. A step 82 having a circular cross section is attached to the side surface of the exterior 51. Steps 81 and 82 are formed with step grooves so as not to slip when the user puts his / her foot on. In particular, in the present exercise apparatus in which the seat portion 10 swings, it is desirable to form a deep step groove so that the foot does not slip. In addition, step 81 and step 82 may be hung from the seat part 10 besides attaching to an exterior.
A base 14 is disposed on the bottom surface of the seat portion 10. The drive unit 50 transmits the movement to the base 14 through various mechanisms, and the entire seat 10 moves as the base 14 moves.

  The drive unit 50 has an exterior 51 and has various components (see FIG. 3). A hollow cylindrical box 52 is provided inside the exterior 51. A rotation motor 53 is disposed on the inner peripheral wall of the box 52 (see FIG. 4). A spur gear 54 is attached to the tip of the rotary shaft of the rotary motor 53. Further, a groove is formed on the circumference of the upper surface of the box body 52, and a steel ball 55 is loosely fitted in the groove. With this steel ball 55, a disk 56 is supported on the circumference of the upper surface of the box 52 in a horizontal rotation. Teeth are formed on the inner circumference of the bottom of the disk 56 to form an internal gear 57. Accordingly, the spur gear 54 at the tip of the rotary motor and the internal gear 57 are engaged with each other, and the rotary shaft of the rotary motor 53 rotates, whereby the disk 56 rotates through the gears 54 and 57. A shaft 58 is vertically disposed in the upper central portion of the disk 56. The bottom end of the shaft 58 is joined to the disk 56. The upper end of the shaft 58 has a function as a pivot shaft, and a pivot bearing is formed at the center of the bottom surface of the base 14. With this pivot, the base 14 can be tilted in all directions with the shaft 58 as the center point. Since the base 14 tilts in all directions, the seat 10 to be joined can similarly tilt in all directions.

  The shaft 58 is provided with arms 59 symmetrically in the upper left and right portions so that the base 14 rotates horizontally in conjunction with the rotation of the shaft 58 without hindering the tilting of the base 14. Although the base 14 can be tilted by applying the pivot as described above, the rotary motion of the shaft 58 cannot be transmitted to the base 14 in this state, so the arm 59 is provided.

  One end of a rod 60 is attached to the left side surface of the base 14. The other end of the rod 60 is connected to a rotating shaft of a lateral tilt motor 61 disposed on a bracket screwed on the left inner surface of the exterior 51. The rotation shaft of the lateral tilting motor 61 is bent twice, and the rotation of the motor is eccentric and transmitted to the rod 60. Then, the rod 60 moves up and down by the rotation of the motor, and the base 14 to which the rod 60 is attached tilts in the lateral direction. In addition, it is preferable to apply a motor with a reduction gear to the lateral tilting motor 61.

  One end of a rod 62 is attached to the back side surface of the base 14. The other end of the rod 62 is connected to a rotation shaft of a longitudinal tilt motor 63 disposed on a bracket screwed on the rear inner surface of the exterior 51. The rotating shaft of the longitudinal tilting motor 63 is bent twice, and the rotation of the motor is eccentric and transmitted to the rod 62. Then, the rod 62 moves up and down by the rotation of the motor, and the base 14 to which the rod 62 is attached moves in the vertical direction. In addition, it is preferable to apply a motor with a reduction gear to the lateral tilting motor 61.

  A support frame 90 serving as a leg is joined to the bottom of the exterior 51. A caster 91 is rotatably disposed at the rear portion of the support frame 90. Therefore, by lifting the front of the support frame 90 and tilting the entire exercise device backward, and applying the own weight of the exercise device to the caster 91, the caster rotates so that the coefficient of friction can be reduced and the exercise device can be easily moved. .

  The grip part 30 has a hollow rod 31 at the top. A grip 32 held by the user is disposed at both ends of the hollow rod 31. This grip 32 is used when the elbow support 11 is closed and seated in a horse riding posture toward the rear (see FIG. 6).

  Next, a use operation when the exercise device according to the present embodiment is used in a sitting posture will be described. When the elbow support 11 is in an open state, the user sits on the seating surface of the seat 10 with his / her feet on the step 81 in a sitting posture (see FIG. 5). The operation panel 12 is provided with a “start / stop” switch and a “speed” switch. While sitting on the seat portion 10, the user holds the left grip bar 20 with the left hand and presses the “start / stop” switch on the operation panel 12 with the right hand. After operating the operation panel 12, the user holds the right grip bar 20 with the right hand. Then, based on the output signal from the “start / stop” switch, the control unit composed of a microcomputer drives the lateral tilting motor 61 and tilts the seat 10 repeatedly in the lateral direction via the rod 60. The control unit stops the driving of the lateral tilting motor 61 by setting the lateral tilting motor 61 to the predetermined initial position. In this way, by returning the position of the rod 60 to the predetermined initial position, it is possible to stop the seat portion 10 without being tilted.

Since the user uses the external oblique muscles and the like to try to balance the body each time the tilting of the seat 10 is performed by the lateral tilting motor 61, the used muscles can be strengthened.
The control unit drives the vertical tilting motor 63 to tilt the seat unit 10 repeatedly in the vertical direction via the rod 62. The control unit stops the drive of the vertical tilt motor 61 by setting the vertical tilt motor 63 so that the position of the rod 62 becomes a predetermined initial position.
Since the user uses the rectus abdominis muscle, latissimus dorsi muscle and the like to try to balance the body with each tilt, the user can reinforce the used muscles by tilting the seat 10 by the vertical tilt motor 63.
When the control unit is driving the lateral tilt motor 61 or the vertical tilt motor 63, the user can also press the operation panel “speed” switch. Thus, the horizontal tilt motor 61 or the vertical tilt motor 63 can be rotated. By adjusting such a speed, a user-desired movement can be provided.

  The controller drives the horizontal tilt motor 61 and / or the vertical tilt motor 63 to rotate the rotary motor 53 in a state where the seat portion 10 is tilted. The spur gear 54 mounted on the rotation shaft of the rotary motor 53 rotates, and the spur gear 54 and the internal gear 57 are engaged with each other, so that the disk 56 rotates. By the rotation of the disk 56, the shaft 58 joined to the disk 56 is also rotated, the base 14 is rotated through the arm 59, and the seat portion 10 is rotated. The controller drives the rotary motor 53 in the forward direction and then in the reverse direction. A well-known linear encoder is disposed on the disk 56 or the shaft 58 so that the control unit can detect how much the shaft has rotated. Based on the detection signal from the linear encoder, the control unit rotates the seat portion 10 by a predetermined angle, reversely rotates the seat portion 10 to return to the initial position, and further rotates the seat portion 10 by a predetermined angle in the opposite direction. Here, the predetermined angle is initially small when the rotary motor 53 is driven, and the control unit can execute control to increase the predetermined angle with time.

The user further rotates the seat 10 horizontally with the seat tilted in the vertical and / or horizontal direction, making it difficult to balance the user and allowing the user to perform more heavy exercise. Can do.
Further, the control unit can control the driving of the lateral tilt motor 61, the vertical tilt motor 63, and the rotary motor 53 in combination, and the user can perform an exercise with higher load.

  Next, a use operation when the exercise device according to the present embodiment is used in the riding posture will be described. The user turns the elbow receiving portion 11 in the open state to the closed state so that the outer side surface of the elbow receiving portion 11 faces upward (see FIG. 2), and the rear side faces the outer side surface of the elbow receiving portion 11. Sit across and facing (see FIG. 6). The operation panel 12 becomes invisible due to the rotation of the elbow support portion 11 and cannot be operated, and the operation panel 21 disposed on the back portion of the seat portion 10 is operated with the right hand. The left hand holds the left grip 32 of the grip 30. The operation panel 21 has the same switch arrangement as the operation panel 12. Similarly to the use in the sitting posture, the operation panel 21 is operated to drive the drive unit 50. Since the driving of the driving unit 50 is the same as that used in the sitting posture, description thereof is omitted. Despite the same driving content as that used in the sitting posture, the user's experience is greatly different. For example, the driving in which the seat portion 10 is tilted forward from the horizontal state when used in the sitting posture facing forward, and the state where the seat 10 is tilted rearward from the horizontal state when used in the riding posture is used. Become. The fact that the sensation is different even in such a simple driving of the seat portion 10 means that the sensation of the user is greatly different in the complicated driving combining the driving of a plurality of motors. Further, the difference in body sensation is based not only on the difference between the front-facing state and the rear-facing state, but also on the difference in posture between the sitting posture and the riding posture. Furthermore, the front view and the rear view are visually different, and there are many influences caused by this difference.

  [Grip Housing Structure] In the present embodiment, the grip 32 can be retracted into the hollow rod 31 and can be stored. In order to obtain a storage structure, the hollow trough 31 can be formed into a thick flat plate shape.

  [Configuration only for sitting in a sitting position] In the present embodiment, an exercise device that can be used while sitting in a sitting position or a riding position has been described. However, the elbow support unit 11 does not rotate as shown in FIG. If it is an exercise device only in this state, the exercise device can be used only in a sitting posture.

(First embodiment of the present invention)
An exercise device according to a first embodiment of the present invention will be described with reference to the drawings. 7 is an overall perspective view of the exercise device according to the present embodiment in an open state, FIG. 8 is an overall perspective view of the exercise device according to the present embodiment in a closed state, and FIG. 9 is an open state of the exercise device according to the present embodiment. FIG. 10 is a usage explanatory diagram of the exercise device according to the present embodiment in a closed state.

The seat portion 100 that can be seated in a sitting posture toward the front and seated in a horse riding posture in the lateral direction has a concave shape with a gentle streamline in the front view and the upper portion in a side view. It is a convex shape consisting of a gentle streamline. Because of this shape, when the user is seated in a sitting posture toward the front, the buttocks are stably supported by a seat surface that is curved in an inverted arc shape (see FIG. 9). When seated sideways in a horse riding posture, the buttocks and inner thighs are stably supported by a seating surface curved in an arcuate shape (see FIG. 10).

In addition, one end of the step frame 110 is connected to the front surface of the seat portion 100, a step 111 for placing a foot is connected to the other end of the step frame 110, and one end of the backrest frame 120 is connected to the back surface of the seat portion 100. (For example, a structure in which the bracket of the backrest frame 120 is attached to the shaft in the back direction), and is formed on the other end of the backrest frame 120 from the bottom to the top and in the back direction at the top. A bent backrest 121 is provided. In the case where the backrest 121 is disposed such that the end of the backrest 121 of the backrest frame 120 faces upward, the upper portion of the backrest 121 projects rearward and functions as a backrest. A hollow rod 131 having a circular cross section is joined to the bent portion of the backrest 121. Since it is joined to the bent portion of the backrest 121, the contact surface can be widened and can be joined stably. A circular grip 132 is also provided at both ends of the hollow rod 131 to constitute a grip 130. When the backrest frame 120 is rotated along the back surface of the seat portion 100 and the backrest 121 is positioned downward, the protruding portion of the backrest 121 functions as a step. Therefore, step 110 and step 111 used in the sitting posture can be used for the other step frame and step without providing one step frame and step.
A stable posture can be obtained by placing a foot on the step 111 and sitting in a sitting posture.

  Grip bars 101 serving as grip portions are attached to the upper portions on both sides of the seat portion 100. The grip bar 101 is a grip for the user to hold when the user is seated in a sitting posture facing forward. The grip bar 101 has a depth slightly more than twice that of the back of a human hand so that the grip bar 101 can be gripped even when seated in a riding posture. Thus, since the grip bar 101 is a long bar, it is easy to grip in the riding posture and the sitting posture.

An operation panel is formed immediately below the grip bar 101. By forming the operation panel near the grip bar 101, the grip bar 101 is clamped to the operation panel, and conversely, the operation panel is clamped to the grip bar 101. It is easy to use and can be instantly migrated.
Air cells are arranged on both lateral sides of the seat portion 100, and the user can be stably held by expansion by air supply from an air pump and a compressor (not shown).

  Next, the use operation of the exercise device according to the present embodiment will be described.

In this state, the user sits in a sitting posture and operates the operation panel to drive the drive unit 50 (see FIG. 9). On the other hand, when the user sits sideways in a riding posture, the backrest frame 120 is rotated along the back surface of the seat portion 100 so that the backrest 121 is positioned downward (see FIG. 10). By doing so, the backrest 121 performs the function of a step. In this state, the user sits sideways in a riding posture and operates the operation panel to drive the drive unit 50.

  When the user uses the sitting posture, the sensation is substantially the same as when the user uses the sitting posture in the first embodiment. On the other hand, when a user uses in a riding posture, for example, the movement in the vertical direction until now is experienced by the movement in the horizontal direction to sit down, even if the driving content is the same as the sitting posture You can feel differently.

  [Configuration only for sitting in a sitting position] In the present embodiment, an exercise device that can be used while sitting in a sitting position or a riding position has been described. However, the back frame 120 of FIG. 7 does not rotate. If the exercise device is in a state only, the exercise device can be used only in a sitting posture. Further, the user's back is supported by the back frame 120 and the back 121, but the shape of the seat 100 is changed, and the structure is formed by bending upward at the rear side so as to also serve as the back. You can also.
