A second attachment hole 21 to which the second support shaft 9 is attached is formed in the lower portion of the second attachment portion 18 so as to penetrate in the left-right direction.
[Drive mechanism]
The drive mechanism 52 shown in FIG. 2 to FIG. 5 has a single drive motor 23 arranged so that one rotary shaft 54 that outputs a rotational force faces forward. , Provided on the support substrate 24 on the left side of the pedestal 16. The drive mechanism 52 has a branching mechanism 55 that immediately separates the rotation of the rotary shaft 54 into two, and one rotational force branched by the branching mechanism 55 drives the up-and-down motion mechanism 50, and the other branched rotation. The force drives the left-right motion mechanism 51.

Specifically, the branch mechanism 55 includes a worm gear 56 provided at the tip of the rotation shaft 54 of the drive motor, and a pair of gears 57 that are screwed to the worm gear 56 and disposed above and below the rotation shaft 54 of the drive motor. , 58 (upper gear, lower gear).
The upper gear 57 is connected to one end of a first drive shaft 53 disposed so as to face in the left-right direction. One end of a second drive shaft 59 arranged to face the left and right direction is connected to the lower gear 58. At the other end of the second drive shaft 59, a drive gear 37 for transmitting a rotational force to the left-right motion mechanism 51 is provided. Therefore, the second drive shaft 59 is positioned below the first drive shaft 53. Since the upper gear 57 and the lower gear 58 have the same number of teeth and are arranged so as to sandwich the worm gear 56 from above and below, when the drive motor 23 is operated, the first drive shaft 53 (the first support shaft 8). ) And the second drive shaft 59 rotate at the same rotational speed in opposite directions.

Thus, even if the output of the drive motor 23 is increased by arranging a pair of gears from above and below so as to press the worm gear 56 of the rotating shaft 54, the upper gear 57 and the worm gear 56 or the lower gear 58 and the worm gear are increased. 56 is prevented from jumping out of teeth, and a reliable rotational force can be transmitted.
When the first drive shaft 53 is rotated by the drive motor 23 to cause the first support shaft 8 to perform an eccentric circular motion, the first mounting portion 17 performs a crank motion, and the pedestal portion 16, that is, the front portion of the seat 2 moves. Reciprocate up and down with respect to the first support shaft 8.
[Left-right motion mechanism]
The left and right motion mechanism 51 shown in FIGS. 6 and 7 includes a swing member 28 that reciprocates the seat 2 straight back and forth, a slide support shaft 29 that slidably supports the swing member 28 in the left and right directions, and a swing shaft. A cylindrical guide member 30 that slides the moving member 28 along the axial direction of the slide support shaft 29 is provided.

The swing member 28 has a main body 28a attached to the slide support shaft 29 and a protrusion 28b protruding upward from the main body 28a. The main body 28a has a rectangular plate shape or box shape in plan view. An insertion hole 28c through which the slide support shaft 29 is inserted is formed in the main body portion 28a so as to penetrate in the left-right direction. The insertion holes 28c are formed at two positions on the front and rear of the main body portion 28a.
The protrusions 28b are paired left and right, and the protrusions 28b are spaced apart by a predetermined distance in the left-right direction.

On the other hand, a connecting shaft 32 is provided on the inner side of the pedestal 16 so as to enter between the pair of protrusions 28b. The connecting shaft 32 faces a direction (front-rear direction) orthogonal to the slide support shaft 29, and both end portions thereof are fixed to the front-rear wall portions of the pedestal portion 16. In this way, when the connecting shaft 32 enters between the pair of projecting portions 28 b, the pedestal portion 16 (seat 2) is interlocked with the swing of the swing member 28. By doing so, the swinging member 28 of the seat 2 can be easily attached and detached.
The rocking member 28 is supported by a slide support shaft 29 in two spaced apart in the front-rear direction. Each slide support shaft 29 is provided in parallel with the first support shaft 8 and the second support shaft 9, and is inserted through the insertion hole 28 c of the swing member 28. Both ends of the slide support shaft 29 are supported by support brackets 31 provided on the upper surface of each support member 25.

A guide pin 34 that fits into the guide member 30 is provided on the lower surface of the main body 28a so as to protrude downward. A spiral and endless cam groove 35 into which the guide pin 34 is fitted is formed on the outer peripheral surface of the guide member 30.
The guide member 30 is pivotally supported by pivot shafts 36 provided integrally at both ends thereof. The pivot shaft 36 is concentric with the guide member 30 and parallel to the first pivot shaft 8. Both ends of the pivot shaft 36 are rotatably supported by the left and right support members 25. Yes.
As shown in FIG. 5, a drive gear 37 is provided on the other side of the second drive shaft 59 provided in the drive mechanism 52, and this drive gear is provided at the end of the pivot shaft 36 of the guide member 30. A driven gear 38 that meshes with 37 is provided. The number of teeth of the drive gear 37 and the driven gear 38 is, for example, 21 for the drive gear 37, 56 for the driven gear 38, 22 for the drive gear 37, or 56 for the driven gear 38.

When the second drive shaft 59 is rotated by the drive motor 23 of the drive mechanism 52, this rotation is transmitted from the drive gear 37 to the driven gear 38, so that the pivot shaft 36 of the guide member 30 rotates about its axis. It has become. The guide member 30 also rotates around the pivot shaft 36, so that the distal end portion of the guide pin 34 fitted in the cam groove 35 slides along the cam groove 35 as the guide member 30 rotates. It has become.
When the guide member 30 rotates, the guide pin 34 fitted in the cam groove 35 reciprocates left and right while sliding along the cam groove 35. In the seating type exercise apparatus 1, the swinging member 28 swings left and right by the reciprocating motion of the guide pin 34 in the left-right direction, and accordingly, the connecting shaft 32 attached to the swinging member 28 swings left and right. Thus, the seat 2 is moved back and forth in a straight line.

  At this time, since the ratio of the number of teeth of the drive gear 37 and the driven gear 38 is 21:56 or 22:56, the motion cycle of the left-right motion mechanism 51 is greater than twice the motion cycle of the vertical motion mechanism 50. It ’s about 8/3, and it ’s possible to eliminate monotonous repetitive movements such as “the front part goes up when moving to the right” and “the front part goes up when moving to the left”. The user can feel a sense of realism. Furthermore, since the motion cycle of the left and right motion mechanism 51 is not an integral multiple of the motion cycle of the vertical motion mechanism 50, the position in the left and right direction where the front part is the highest is moved little by little. It is possible to exclude the seat from swinging up and down at the position.

As described above, in the seating type exercise apparatus 1 according to the present invention, the vertical movement mechanism 50 and the left and right movement mechanism 51 are simultaneously operated by the drive mechanism 52, so that the seat 2 on which the user is seated is the vertical movement. The user can perform an effective balance exercise that has never been achieved by performing an exercise in which left and right exercises are mixed.
The present invention is not limited to the above embodiment.
The ratio of the number of teeth of the drive gear 37 and the driven gear 38 is not limited to 21:56, that is, 3: 8, and may be 1: 4 or 1: 8, for example.
