In the training apparatus according to the present invention, the seat reciprocates and reciprocates by the driving unit. Therefore, not only the overall structure of the training apparatus can be simplified, but also manufacturing and troubleshooting are easy.

1 and 2, a training apparatus 100 according to an embodiment of the present invention is illustrated. Referring to FIG. 1, a training apparatus 100 includes a seat 190, a support member 160, and a driver 180. The seat 190 is a component in which the user is seated. The support member 160 is fixed to the lower surface of the seat 190. However, the structure in which the support member 160 and the seat 190 are coupled is not limited to this. When the support member 160 is fixed so as not to move with respect to the seat in the first direction (hereinafter referred to as " do.

The driving unit 180 moves the seat 190 in the second direction (hereinafter referred to as "forward and backward direction") with one position 161 of the supporting member as the rotational center, while reciprocating the seat 190 in the left- . Hereinafter, the lateral direction, the front-rear direction, and the third direction (hereinafter referred to as "vertical direction") are perpendicular to each other. The driving unit 180 includes a driving source 183, a first motion converting mechanism 130, and a second motion converting mechanism 140. The driving source 183 provides rotational force, and includes a rotation unit 170 and a motor (not shown). The motor (not shown) is directly or indirectly connected to the rotation unit 170 to rotate the rotation unit 170. Further, two driving sources may be provided to provide the rotational motion to the first motion converting mechanism 130 and the second motion converting mechanism 140, respectively, but only one driving source may be installed to reduce the manufacturing cost. In this embodiment, one drive source 183 is disposed.

The first motion converting mechanism 130 converts the rotational motion of the driving source 183 to linearly reciprocate the supporting member 160 in the left-right direction. The first motion converting mechanism 130 includes a first connecting member 131, a second connecting member 132, and a third connecting member 133. One end of the first linking member 131 is rotatably connected at a position eccentric to the center of rotation of the rotation unit 170 in a revolute joint structure. The first linking member 131 moves by the rotation of the rotation unit 170. [

Referring to FIGS. 1 and 2, the second linking member 132 is coupled to the support member 160 so as to reciprocate linearly with respect to the left-right direction. The supporting member 160 is formed with a penetrating portion 160a. A bearing 165 is disposed on the penetrating portion 160a and a first screw thread 165a is formed on an inner circumferential surface of the bearing. A second screw thread 132a screwed to the first screw thread 165a is formed on an outer circumferential surface of a portion included in a region where the support member 160 moves in the second connection member 132. [ Therefore, when the second linking member 132 rotates, the support member 160 linearly reciprocates in the left-right direction.

Referring to FIG. 1, one end of the third connecting member 133 is connected to the first connecting member 131 so as to be rotatable relative to the first connecting member 131, and the other end is fixed to the second connecting member 132. The third linking member 133 and the first linking member 131 are connected in a level route joint structure. When the rotation part 170 rotates, the first connection member 131 moves and the third connection member 133 moves and the second connection member 132 rotates by the movement of the third connection member 133 do.

3 is a schematic view showing the rotation mechanism of the second linking member 132 by the rotation of the rotation unit 170. FIG. 3, the coupling position 162 of the rotation part 170 and the first connection member 131 from the rotation center C1 of the rotation part 170 has an angle?. When the rotation part 170 rotates in the counterclockwise direction, the angle? Gradually increases so that the third linking member 133 is positioned at the coupling position 163 of the second linking member 132 and the third linking member 133, And rotates counterclockwise. Since the third linking member 133 is fixed to the second linking member 132, the second linking member 132 is also rotated counterclockwise by the counterclockwise rotation of the third linking member 133, do. That is, the rotary part 170, the first linking member 131, and the third linking member 132 form the first thread link structure, and the second link member 132 is rotated by the first thread link structure, And reciprocates linearly in the lateral direction.

1, the second motion converting mechanism 140 converts the rotational motion of the rotating part 170 to rotate the seat 190 in the forward and backward directions with the one position 161 of the supporting member 160 as the rotational center As shown in Fig. The second motion converting mechanism (140) includes the auxiliary rotating portion (150) and the fourth connecting member (134). The auxiliary rotation unit 150 is rotated by the rotation unit 170. The auxiliary rotation unit 150 and the rotation unit 170 have different revolutions per unit time. The ratios of the rotation speeds of the auxiliary rotation unit 150 and the rotation unit 170 can be variously set, but in this embodiment, the ratio of the rotation numbers is set to 2: 1 so that the seat moves while drawing the "eight character" trajectory .

Although not shown, the auxiliary rotation unit 150 is gear-engaged with the rotation unit 170, so that the auxiliary rotation unit 150 rotates by the rotation of the rotation unit 170. However, the present invention is not limited to this, and the auxiliary rotation unit 150 and the rotation unit 170 may be coupled by a belt, a chain, or the like. 4, the auxiliary rotation unit 150 is supported by the auxiliary rotation shaft 151 on the frame 10, and the auxiliary rotation unit 150 is slidable on the auxiliary rotation axis 151 in the lateral direction. However, the coupling structure of the auxiliary rotation unit 150 and the fourth connection member 134 is not limited to the above. 5, the fourth linking member 234 has a bent portion 234a substantially parallel to the second linking member 132 and the bent portion 234a is inserted into the through hole 250a of the auxiliary rotating portion 250 As shown in FIG. The bent portion 234 slides in the through hole 250a of the auxiliary rotation portion 250 when the fourth linking member 234 moves in the left and right direction in the left and right reciprocating motion of the seat 190. [ At this time, the auxiliary rotation unit 250 is supported by the auxiliary rotation shaft 251 and is fixed so as not to move in the left-right direction.

1 and 3, one end of the fourth linking member 134 is rotatably connected to a position eccentric from the rotation center of the auxiliary rotation unit 150, and the other end is fixed to the support member 160 . However, the fourth connecting member 134 may be fixed to the seat 190 instead of the supporting member 160. The fourth linking member 134 is level-routed jointly with the auxiliary rotation unit 150.

6 to 9 are schematic views showing the rotation mechanism of the seat 190 by the rotation of the auxiliary rotation unit 150. As shown in FIG. 6, when the engagement position 151 of the fourth connection member 134 and the auxiliary rotation unit 150 is in the first position P1, the seat 190 remains flat. When the auxiliary rotation part 150 is rotated clockwise by the rotation of the rotation part 170 in the counterclockwise direction, the fourth connection member 134 pulls the support member 160 backward, 161 in the clockwise direction. 7, when the engagement position is in the second position P2, the seat 190 is tilted backward. Thereafter, when the auxiliary rotation part 150 further rotates, the fourth connection member 134 pushes the support member 160 forward, so that the seat 190 rotates counterclockwise . Referring to Fig. 8, when the engaging position is at the third position P3, the seat 190 returns to a flattened state. When the auxiliary rotation unit 150 further rotates so that the engagement position is at the fourth position P4, the fourth engagement member 134 pushes the support member 160 forward, and as shown in FIG. 9, 190 are inclined forward. Thereafter, when the engaging position returns to the first position Pl, the seat 190 becomes flat again. Therefore, when the auxiliary rotation unit 150 performs one rotation, the seat 190 performs the oscillating motion once in the forward and backward directions. In this embodiment, since the auxiliary rotation part 150 makes two rotations when the rotation part 170 makes one rotation, the seat 190 rotates once while the seat 190 reciprocates once in the left- Two oscillations are performed in the forward and backward directions. As described above, the auxiliary rotary part 150, the third connecting member 133, and the supporting member 160 form the second thread link structure, and the rotational movement is converted into the reciprocating motion of the seat by the second thread link structure .

Figs. 10 to 16 show operational diagrams showing the coupling relationship of the components with time and the movement process of the seat 190 when the rotation unit 170 rotates once. Referring to FIGS. 10 to 16, when the rotation unit 170 rotates counterclockwise once, the auxiliary rotation unit 150 rotates clockwise two times. At this time, the seat 190 performs a linear reciprocating motion once in the left and right directions and reciprocating motion twice in the forward and backward directions. For details of the linear reciprocating motion and the reciprocating oscillating motion, see the above description.
