The front support members 42 and 42 and the rear support members 43 and 43 are held in parallel with each other at a predetermined interval in the front-rear direction.

  The front horizontal shaft 37 is integrally formed with a front rotating member 40 having a thicker bar than the front horizontal shaft 37 and having a circular cross section in an eccentric state in the axial center of the front horizontal shaft 37. Is attached. One end portion (left end in FIG. 10) of the front horizontal shaft 37 is connected to a speed reduction portion 32 of the drive mechanism 21 described later, and the front portion is rotated as the front horizontal shaft 37 rotates when the drive mechanism 21 is operated. The rotating member 40 rotates eccentrically around the front horizontal shaft 37.

A rear rotating member 41, which is thicker than the rear horizontal shaft 38 and has a circular cross section, is integrally attached to the rear horizontal shaft 38 in an eccentric state at the axial center of the rear horizontal shaft 38. Yes.
In the case of this embodiment, as shown in FIG. 11, the eccentric direction of the front rotating member 40 with respect to the front horizontal shaft 37 and the eccentric direction of the rear rotating member 41 with respect to the rear horizontal shaft 38 are substantially opposite directions. ing.

On the other hand, as shown in FIG. 12, the pair of left and right front connection members 44, 44 have a bearing portion 50 on the lower end side, and the pair of left and right rear connection members 45, 45 have a bearing portion 51 on the lower end side. have.
Each bearing portion 50 of the front connecting member 44 is formed with a holding hole 50a capable of rotatably holding the front rotating member 40. The front rotating member 40 is inserted into the holding hole 50a in a state where it can slide and rotate. Similarly, each bearing portion 51 of the rear connecting member 45 is formed with a holding hole 51a capable of rotatably holding the rear rotating member 41. The rear rotating member 41 is inserted into the holding hole 51a so as to be slidably rotatable. A state in which the front connecting member 44 and the rear connecting member 45 are attached to the front rotating member 40 and the rear rotating member 41 is shown in FIG.

The upper end side of the pair of left and right front connection members 44 and 44 and the upper end side of the pair of left and right rear connection members 45 and 45 are connected to the box frame 54.
The box frame 54 includes a pair of left and right frame constituent members 52 having an inverted U shape in a side view, and a tie rod 53 that connects the two frame constituent members 52. As shown in FIGS. 5, 7, and 8, the left and right frame components 52 are provided with front mounting ribs 55 that are bent inwardly on the front side so as to be attached to the left and right front mountings. A lower holding member 57 on the front side is attached so as to connect the ribs 55, 55. Each of the left and right frame components 52 is provided with rear mounting ribs 56 that are bent in an inwardly opposing manner on the rear side, and the lower parts on the rear side are connected so as to connect the left and right rear mounting ribs 56, 56. A holding member 57 is attached.

The upper end sides of the pair of left and right front connection members 44, 44 are connected to the front part of the frame component 52, and the upper ends of the pair of left and right rear connection members 45, 45 are connected to the front part of the frame component 52. ing.
Since the front-rear motion mechanism 22 has the above-described configuration, when the front horizontal shaft 37 rotates and the front rotation member 40 starts to rotate eccentrically by the operation of the drive mechanism 21, the front rotation is performed. As the member 40 rotates eccentrically, the front connecting member 44 also starts to move back and forth and up and down. Since the rear connecting member 45 is integrated with the front connecting member 44 by the box frame 54, when the front connecting member 44 moves forward and rearward, it moves back and forth so as to follow them. (The rear rotating member 41 reciprocally rotates so as to move back and forth below the rear horizontal shaft 37).
These movements are taken out as movements of the box frame 54 and become a back-and-forth three-dimensional movement by the front-rear movement mechanism 22.

[Left-right motion mechanism]
As shown in FIGS. 5 to 9 and 13, the left-right motion mechanism 23 is composed of a pair of front and rear four-bar links 60.

  Each four-bar link 60 is arranged on the left and right, and the lower base shafts 61 and 61 whose axis is directed in the front-rear direction, the lower holding member 57 to which the lower base shafts 61 and 61 are attached, and the left and right are arranged on the front and rear. The upper base shafts 62, 62 facing the direction, the support frame 27 to which the upper base shafts 62, 62 are attached, and the left and right swing arms 65, 66 connecting the upper base shafts 62, 62 and the lower base shaft 61 are formed. Yes.

As shown in FIG. 13, the support frame 27 is formed in a cross beam shape by two vertical bars 25, 25 and two horizontal bars 26, 26 connecting the vertical bars 25, 25. An upper holding member 63 is bridged between the longitudinal rails 25, 25 on the front and rear sides of the support frame, and the seat 3 is attached to the upper surfaces of the longitudinal rails 25, 25 and the lateral rails 26, 26. It has become.
The connection status of each member is as follows.

  The lower holding member 57 and the lower end of the left swing arm 65 are rotatably connected via the left lower base shaft 61. The upper end portion of the left swing arm 65 and the upper holding member 63 of the support frame 27 are rotatably connected via the left upper base shaft 62. Further, the lower holding member 57 and the lower end portion of the right swing arm 66 are rotatably connected via the right lower base shaft 61. An upper end portion of the right swinging arm 66 and the upper holding member 63 are rotatably connected to each other through the right upper base shaft 62.

Compared to the distance between the lower base shafts 61 and 61 (left-right spacing) described above, the distance between the upper base shafts 62 and 62 (left-right spacing) is wider, and the left swing arm 65 and the right swing arm 66. Means to maintain a positional relationship (a state of spreading upward) that always spreads upward.
For these reasons, the left swing arm 65 and the right swing arm 66 swing left and right simultaneously on the upper side while using the left and right lower base shafts 61 and 61 as fulcrums. Moreover, when the left swing arm 65 is in an upright state, for example, the right swing arm 66 is inclined to the right so that the upper end of the swing arm 65 is farther away from the left swing arm 65. For example, when 66 is in an upright state, the left swing arm 65 is tilted to the left so that its upper end is farther from the right swing arm 66.

Therefore, the upper holding member 63, that is, the support frame 27, in addition to the repetitive reciprocation in the left-right direction, performs a tilting operation such as a left-down state when moving left and a right-down state when moving right.
As described above, the left-right motion mechanism 23 generates the left-right / up-and-down motion, so that the support frame 27 moves in the same manner, and as a result, the seat 3 performs the left-right / up-down three-dimensional motion.

[Drive mechanism]
On the other hand, the drive mechanism 21 has one electric motor 30 and a transmission mechanism 31. The electric motor 30 is disposed close to one short side 20a of the base body 20, and is vertically disposed with the axis of the rotation drive shaft directed in the front-rear direction. On the other hand, the output shaft of the speed reducing portion 32 protrudes with the axis centered in the left-right direction.
As shown in FIGS. 9 to 11 and 14, the transmission mechanism 31 is connected to a first output unit 70 (longitudinal motion output unit) that transmits the rotational force of the electric motor 30 to the longitudinal motion mechanism 22 and to the left and right motion mechanism 23. It has the 2nd output part 71 (left-right movement output part) which transmits. The second output unit 71 is provided between the pair of four-bar links 60, 60 (a region sandwiched between the front and rear four-bar links 60).

The first output unit 70 includes a worm gear and the like, and has a speed reduction unit 32 to which the rotation of the electric motor 30 is input. The output of the speed reduction unit 32 is transmitted to the front horizontal shaft 37. Yes. That is, the rotation of the electric motor 30 is decelerated by the deceleration unit 32, and the front horizontal axis 37 is rotated by the decelerated rotation, so that the longitudinal movement mechanism 22 moves.
On the other hand, the second output unit 71 is connected between the second speed reduction part 72 connected to the shaft end opposite to the speed reduction part 32 with respect to the front horizontal shaft 37 and the left and right bearing bases 33 and 34. An output shaft 73 that is rotatably held and is rotated by a rotational driving force output from the second speed reduction portion 72 and a cylindrical cam 78 that is provided coaxially at a substantially central portion of the output shaft 73 are provided. Further, the second output unit 71 includes a guide bar 80 installed with the axis centered in the left-right direction above the left and right bearing bases 33 and 34, and a slider 81 slidably held along the guide bar 80. And have. An endless cam groove 82 meandering along the circumferential direction is formed on the outer peripheral surface of the cylindrical cam 78, and a slider 83 that protrudes downward and engages the cam groove 82 is formed on the lower surface of the slider 81. Is provided.

A pair of left and right projections 85, 85 are provided on the upper surface of the slider 81, and a shaft gripping groove 86 is formed between the projections 85, 85. On the other hand, the support frame 27 is provided with a shaft 87 between the upper holding members 63 attached to the front and rear of the support frame 27, and the shaft 87 is fitted into the shaft holding groove 86 without rattling. .
With the configuration of the second output unit 71, the rotation of the electric motor 30 decelerated by the second reduction unit 72 is transmitted to the output shaft 73, and the cylindrical cam 78 rotates in synchronization with the output shaft 73. As the cam 78 rotates, the slider 83 slides in the cam groove 82, and the slider 81 reciprocates in the left-right direction. As the slider 81 reciprocates in the left-right direction, reciprocation in the left-right direction is transmitted to the support frame 27 as well. The reciprocating motion transmitted to the support frame 27 becomes a left-right three-dimensional motion by the left-right motion mechanism 23 described above.

  Note that the reduction ratio of the second reduction portion 72 is set to 1: 2, and the cylindrical cam 78 is rotated once by rotating the front horizontal shaft 37 twice. Therefore, when the front horizontal shaft 37 is rotated twice and the front / rear and vertical movements are performed twice, the slider 81 is reciprocated once and the horizontal movement is performed once.

[Mode of operation]
Next, an operation mode of the seated exercise apparatus 1 having the above-described configuration will be described.
The user M first sits in such a posture as to straddle the seat 3, places his / her foot on the pedal 10 according to his / her preference, and then turns on the start switch using the operation panel unit 15.
Then, the drive mechanism 21 drives the back-and-forth motion mechanism 22 via the first output part 70 of the transmission mechanism 31 and drives the left-right motion mechanism 23 via the second output part 71 of the transmission mechanism 31.

  In the back-and-forth motion mechanism 22, the back-and-forth reciprocation is performed together with the front connecting member 44 that moves back and forth by the eccentric rotation of the front turning member 40 and the rear turning member 41 provided on the rear horizontal shaft 38. The rear connecting member 45 that only repeats swinging moves simultaneously so that the seat frame 3 connected to the box frame 54 and the box frame 54 via the left-right motion mechanism 23 moves three-dimensionally back and forth and up and down. Become.

In the left-right motion mechanism 23, the left swing arm 65 and the right swing arm 66 swing simultaneously with the left and right lower base shafts 61 as fulcrums, and accordingly, the support frame 27 connecting the upper ends of both arms 65, 66. In addition, the seat 3 fixed on the support frame 27 moves three-dimensionally from side to side and up and down.
In addition, when the front horizontal shaft 37 is rotated twice and the back and forth and up and down movements are performed twice, the slider 81 is reciprocated once and the left and right up and down movements are performed once. It is a complex movement that combines left and right three-dimensional movement. When the movement of the seat 3 is viewed in plan as shown in FIG. 15, the seat 3 reciprocates in the first inclination direction A inclined at an angle θ with respect to the front-rear direction X, and at an angle −θ with respect to the front-rear direction X. The reciprocating motion in the inclined second inclination direction B is repeated alternately.

  In this way, the seat 3 performs a complicated combination of front and rear, left and right, and top and bottom, and the user M sitting on the seat 3 loses his / her seating balance by the swinging motion of the seat 3, and balance is achieved. Trying to move the upper body in particular, this is an effective exercise for diet and recovery from low back fatigue.

[Second Embodiment]
Next, a second embodiment of the seated exercise device according to the present invention will be described.
As shown in FIG. 16, the second embodiment is greatly different from the first embodiment in that the front connecting member 44 that is fitted to the front rotating member 40 by the bearing portion 50 in the front-rear motion mechanism 22. It is slidable in the left-right direction. In addition, the rear connecting member 45 fitted to the rear rotating member 41 with the bearing portion 50 is slidable in the left-right direction.

  Due to this configuration, the longitudinal motion mechanism 22 itself is also slidable in the left-right direction. When the drive mechanism 21 tries to move the left-right motion mechanism 23 in the left-right direction, the longitudinal motion mechanism 22 also slides to the left and right at the same time. Become. Therefore, the left-right movement is larger than that in the first embodiment, and the user M sitting on the seat 3 can perform a sufficient balance exercise.

[Third Embodiment]
Next, a third embodiment of the seated exercise apparatus according to the present invention will be described.
As shown in FIG. 17, the third embodiment is greatly different from the first embodiment in that the front rotating member 40 is a disk body having a diameter larger than that of the front horizontal shaft 37 in the longitudinal movement mechanism 22. In other words, the pair of front rotating members 40 and 40 are held on both the left and right sides of the front horizontal shaft 37 so as to be integrally rotatable in an eccentric state. Similarly, the rear rotation member 41 is a disc body having a diameter larger than that of the rear horizontal shaft 38, and the pair of rear rotation members 41, 41 rotate integrally with both the left and right sides of the rear horizontal shaft 38 in an eccentric state. Held possible. With this configuration, the amount of material such as plastic forming the front rotation member 40 and the rear rotation member 41 can be reduced, and the cost of the entire apparatus 1 can be reduced.

As shown in FIG. 18, the third embodiment is greatly different from the first embodiment in that the support frame 27 is formed by bending a single iron plate into an inverted U shape in a side view. It is. By doing so, the strength of the support frame 27 can be increased. Further, an opening 90 is provided at the center of the support frame 27 in order to reduce the weight.
In addition, as shown in FIG. 19, in the case of this embodiment, the eccentric direction of the front rotating member 40 with respect to the front horizontal shaft 37 and the eccentric direction of the rear rotating member 41 with respect to the rear horizontal shaft 38 are substantially the same. It has become a direction. In this way, when the front rotating member 40 rotates, the rear rotating member 41 reciprocates back and forth above the rear horizontal shaft 37, which is compared to the first embodiment. It is possible to generate intense back and forth movements.

Furthermore, the third embodiment is greatly different from the first embodiment in the overview of the seated exercise apparatus 1.
As shown in FIGS. 20 and 21, the seated exercise apparatus 1 includes an installation table 2 installed on the floor surface F and a seat 3 supported above the installation table 2.
