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 there is an effect of easy manufacturing and troubleshooting.

1 and 2, there is shown a training device 100 according to one embodiment of the invention. Referring to FIG. 1, the training apparatus 100 includes a seat 190, a case 110, and a driver 180. The seat 190 is a component seated by a user and is connected to the case 100. The case 100 has a rectangular parallelepiped shape in which an upper surface thereof is opened.

The driving unit 180 reciprocates the seat 190 with respect to the first direction (hereinafter, referred to as "front and rear direction"), and moves the case 110 into the second direction (hereinafter, "left and right direction") with the front and rear direction as the rotation axis direction. Reciprocating rocking motion ". Hereinafter, the front-rear direction, the left-right direction and the third direction (hereinafter referred to as "up-down direction") are perpendicular to each other. The driving unit 180 includes a driving source 183, a first motion conversion mechanism 130, and a second motion conversion mechanism 140. The driving source 183 provides a rotational force, and includes a third rotating member 187 and a motor 184. The motor 184 and the third rotating member 187 are directly connected, and the motor 184 rotates the third rotating member 187. Two driving sources may be installed in the first motion converting mechanism 130 and the second motion converting mechanism 140 to provide rotational force, respectively, but only one driving source may be installed to reduce manufacturing costs. In this embodiment, one drive source 183 is disposed.

The 1st motion conversion mechanism 130 converts the rotational motion of the drive source 183, and linearly reciprocates the seat 190 with respect to the front-back direction. The first motion conversion mechanism 130 includes a first rotation member 120 and the first support member 160. The first rotating member 120 is connected coaxially with the third rotating member 187 and receives a rotational force from the third rotating member 187 to rotate the front and rear direction in the direction of the rotation axis. The first rotating member 120 and the third rotating member 187 may be separately manufactured and then combined, but may have an integral structure with each other. The first rotating member 120 includes a main body portion 121 having a cylindrical shape in the center portion thereof, and a guide portion 122 formed in an inclined direction along an outer circumferential surface of the main body portion. The support shaft 121a of the first rotating member is inserted into the bearing (not shown) in the frame 10 and the bearing 110a in the case 110 to rotate.

One end of the first support member 160 is fixed to the seat 190 to support the seat 120. The other end of the first support member 160 is guided and moved by the guide part 122. The other end 160a of the first supporting member has a ball bearing structure in order to reduce friction with the first rotating member 120.

The guide part 122 has a groove shape. Therefore, the other end 160a of the first support member 160 is inserted into the guide part 122 and moves. However, the present invention is not limited thereto, and the guide part 122 may have various structures. That is, referring to FIG. 3, the guide part 122 ′ may be formed to protrude on the main body part 121 to guide the first support member 160.

1, 2, and 4, the guide part 122 may have a closed curve shape. In particular, the projection shape 122a in the A direction of the guide part 122 may have a structure substantially close to an ellipse shape. The depth of the guide part 122 may be set in various ways. Referring to FIG. 5, the depth of the guide part 122 may be formed to have the same depth along the guide part. However, the depth of the guide portion 122 may be formed to change. That is, the depth at a specific position of the guide portion 122 may be different from the depth at another position of the guide portion 122. Referring to FIG. 6, the guide part 122 may include a first groove part that increases in depth along a length direction of the guide part 122, and extends from one end of the first groove part to the other end of the first groove part. A second groove portion that decreases in depth along the 122 may be provided. The seat 190 moves in the vertical direction by the first groove part and the second groove part. When the first support member 160 moves along the first groove, the seat 190 moves downward. When the first support member 160 moves along the second groove, the seat 190 moves upward. The first support member 160 passes through the first groove portion and the second groove portion and reaches the start position of the first groove portion again, and the height of the seat 190 is restored to the original height again.

1, 2 and 7, the second motion conversion mechanism 140 converts the rotational motion of the drive source 183, and the case 110 is reciprocated in the left and right directions with the front and rear direction as the rotation axis direction. Let's do it. The second motion converting mechanism 140 includes a second rotating member 132 and a connecting member 162. The second rotating member 132 receives the rotational force from the third rotating member 187 and rotates. The second rotating member 132 rotates in the left and right direction as the rotation axis direction. The rotating shaft 132a of the second rotating member is supported by the bearing 132b provided in the frame 11. The rotation ratio of the third rotating member 187 and the second rotating member 132 is 1: 2. That is, when the third rotating member 187 rotates once, the second rotating member 132 performs two rotations. Therefore, when the third rotating member 187 rotates once, the first rotating member 120 rotates once and the second rotating member 132 rotates twice. The rotation ratio of the third rotation member 187 and the second rotation member 132 may be variously selected, but when the rotation ratio is 1: 2, the seat 190 may move while drawing a "8-character" trajectory.

In addition, the second rotating member 132 and the third rotating member 187 are gear-coupled. That is, the second rotating member 132 and the third rotating member 187 are coupled in a bevel gear coupling structure. However, the present invention is not limited thereto, and the second rotating member 132 and the third rotating member 187 may have a chain and belt coupling structure.

The second rotating member 132 includes an auxiliary rotating shaft 133. The auxiliary rotation shaft 133 is disposed at a position eccentrically away from the rotation shaft 132a of the second rotation member. In addition, the support shaft 111 is fixed to the case 110. One end of the connecting member 162 is connected to the auxiliary rotary shaft 133 in a spherical joint structure so as to be relatively rotatable, and the other end is connected in a spherical joint structure to be relatively rotatable to the support shaft 111. . Therefore, when the second rotating member 132 moves the connecting member 162 while rotating, the connecting member 162 causes the case 110 to move back and forth in the left and right direction with the rotation center as the center of rotation. By the reciprocating rocking motion of the case 190, the seat 190 makes a reciprocating rocking motion.

8 to 11, the mechanism of the reciprocating rocking motion of the case 190 will be described in detail.

When the position of the auxiliary rotation shaft 133 is in the first rotation position P1, the case 110 maintains a horizontal state. In FIG. 9, the position state of the case 110 is illustrated when the position of the auxiliary rotation shaft 133 is in the first rotation position P1. However, the auxiliary rotary shaft 133 rotates in the counterclockwise direction in association with the rotation of the second rotary member 132, so that the position of the auxiliary rotary shaft 133 is changed to the second rotary position P2, the first rotary member The connecting member 162 pulls the support shaft 111 upward with the rotary shaft 121a as the rotary shaft, and the case 110 is inclined in the left direction. In FIG. 10, the position state of the case 110 is illustrated when the position of the auxiliary rotation shaft 133 is in the second rotation position P2.

However, as the position of the auxiliary rotary shaft 133 moves to the third position P3, the case 110 returns to the horizontal state. Referring to FIG. 9, the position of the case 110 is shown. Thereafter, while the position of the auxiliary rotation shaft 133 moves to the fourth position P4, the connection member 162 pulls the support shaft 111 downward, and the case 110 is inclined in the right direction. In FIG. 11, the position state of the case 110 is shown when the position of the auxiliary rotation shaft 133 is in the fourth rotation position P4.

When the position of the auxiliary rotating shaft 133 is moved back to the first position P1, the case 110 is restored to the initial horizontal position (see FIG. 9). Therefore, when the second rotating member 132 makes one rotation, the case 110 performs the reciprocating rocking motion one time left and right with the front and rear direction as the rotation direction.

From the above, when the third rotating member 187 performs one rotation, the first rotating member 120 makes one rotation while reciprocating the seat once in the front-rear direction. In addition, since the second rotating member 132 makes two rotations by one rotation of the third rotating member 187, the case 110 may have two positions while the seat 190 performs one reciprocating motion in the front and rear directions. Perform reciprocating rocking motion in the direction of rotation. In particular, since the seat 190 is connected to the case 110, the seat 190 also performs two reciprocating swing motions substantially in the left and right directions. The reciprocating motion in the front-rear direction and the reciprocating rocking motion in the lateral direction of the left-right direction cause the seat 190 to move with the trajectory of the "8-character" shape as a whole. However, the movement trajectory of the seat 190 may be changed by adjusting the eccentric distance d between the auxiliary rotating shaft 133 and the rotating shaft 132a of the second rotating member (see FIG. 8). If the auxiliary rotary shaft 133 and the rotary shaft 132a of the second rotary member are concentric, the movement trajectory of the seat has a "C-shaped" shape.

Referring to FIG. 2, the driving unit 190 further includes a second support member 170. The second support member 170 supports the seat 190 with respect to the case 110. One end of the second support member 170 is connected to the seat 190 with the left and right directions in a rotational axis direction, and the other end is connected to the case 110 with the left and right directions in a rotational axis direction. It is. That is, the second support member 170 is connected to the seat 190 and the case 110 in a revolute joint structure.

While the seat 190 linearly reciprocates in the front-rear direction, the second support member 170 reciprocates the seat 190 in the front-rear direction. At this time, the seat 190 oscillates in the front-rear direction with the rotation center at the position S where the end of the first support member 160 and the first rotation member 120 contact.
